Description

The utility model relates to security systems designed to ensure the safety of personnel during the repair or maintenance of industrial equipment.

Every year, thousands of accidents occur during the repair and maintenance of industrial equipment, most of which are the result of a lack of proper control of disconnecting equipment from power sources. To prevent unauthorized supply of liquids, gases, electricity, the method of blocking and informing (LOTO) is used.

The blocking and informing procedure is a set of measures that allow the company to eliminate potentially dangerous situations associated with unauthorized supply of liquids, gases, electricity, which can lead to injury or more serious consequences. The procedure includes turning off the power supply to industrial machines or equipment, protective blocking of energy sources by specialized equipment, and posting warning tags or signs.

The LOTO procedure strictly regulates the use of blocking and locking equipment, warning signs and tags, and also distributes the duties and responsibilities of all employees, one way or another connected with the use of the LOTO system.

As a rule, systems of protective blocking and informing (LOTO) consist of several main elements:

- Blocking device (blocker) - designed to securely fix the energy source in a certain position;

- Tag - contains information about the type of work, start and end time of work, responsible person, etc.;

- Padlock - serves to lock the blocker or directly to the energy source (if there is a built-in lock).

The following can be used as auxiliary elements of the safety blocking and informing system:

- Multiple overlay (hasp) - used in case of work by several employees at the same time and allows each employee to block the equipment with a personal lock;

- Group box - designed to store the keys of padlocks of blockers, which performs the functions of a group blocking control device;

- Locking (lock, tag) station - designed to streamline the storage of locking tools.

The proposed utility model relates to auxiliary elements, namely to group blocking control devices that allow you to regulate and control the use of keys stored in the device from locks of blockers in accordance with a given regulation (instruction) for carrying out repair and / or technical work and, in particular, blocking equipment .

Currently, group boxes are used as a group blocking control device (https://niko.pro/katalog/gruppovaya-blokirovka/zamkovye-mnozhiteli/zamkovye-mnozhiteli_275.html; https://aotb.ru/catalog/gruppovaya-blokirovka /gruppovye-boxy/), including group boxes LATCH TIGHT™ 503, portable group boxes 5600, 5601, 5602, etc. (https://www.virteks.ru/catalog/subgroup/66).

The closest analogue of the proposed utility model is a group box for storing lock keys LATCH TIGHT™ 498А (https://www.virteks.ru/catalog/item/822).

The group box LATCH TIGHT™ 498A, like the above-mentioned currently known similar group boxes, is a portable box with a lid (container) equipped with a handle for carrying the box. Holes are made on the top and side walls of the box lid along their perimeter. On the side walls of the box, also along the perimeter, holes are made that are aligned with the holes on the side wall of the lid when the box is closed. All holes are made with the possibility of passage of the padlock chock through three aligned holes on the top and side walls of the lid and the side wall of the box.

The keys to the blocker locks are placed inside the group box.

Hanging locks, hanging through the specified holes ensure the blocking of the lid on the box.

The procedure for blocking and informing the LOTO system is carried out as follows.

The duty officer, according to the work plan, prepares a workplace for the repair team: blocks the disconnected switching devices: installs the blocker on the blocking point, hangs a padlock on the blocker and places the key to the blocking lock in the group box. A similar sequence of actions is performed with all given blocking points.

In this case, each key from the blocking lock is marked with a corresponding number made on the head of the key.

The permitter installs a lock on the group box and allows the foreman to perform the work. The work manager, accompanied by a duty officer, checks the completeness of the preparatory measures and the readiness of the workplace. After making sure that the equipment is turned off and locked correctly, the work performers put their locks on the group box and start work.

After the work is completed, the work supervisor reports to the duty officer on the completion of work and removes his security lock.

The admitting person makes sure that the work is completed, the workplace is cleaned and all participants in the work have left the work behavior area. Next, the admitting person removes his protective lock from the group box. The keys to the blocking locks become available for unlocking with the subsequent transfer of equipment to work or reserve.

The well-known group box LATCH TIGHT™ 498A, like other well-known boxes made in the form of a portable box, has rather large dimensions, which makes it inconvenient to work with it, and, in addition, requires the arrangement of a special place for its storage.

In addition, the keys to the locks of the blockers are stored in the box of the box in an arbitrary order, without being fixed in a certain place, while it is visually impossible to determine which keys are in the closed box. These design features of known boxes make it difficult to find and identify keys in the box.

The present utility model is based on the task of creating a group blocking control device having small dimensions in order to simplify the operation of such a device.

Also, the objective of this utility model is to provide an ordered storage of lock keys with the ability to view the key head, which also simplifies the operation of the device.

The problem is solved by the fact that in the group lock control device, which includes a container for storing the key from the blocker lock, containing a bottom, side walls and a lid, and a means for locking the container with a padlock, according to the proposed utility model, the device contains two plates interconnected hinge with the possibility of their radial displacement relative to each other and alignment of the plates with each other with the formation in the first section of the first and second plates of a container for storing the key from the blocker lock, the bottom of which is made on the first plate, and the cover on the second, while on the second section of each plate there is a flange forming a groove for the longitudinal side edge of the opposite plate, and holes that are aligned when connecting the plates with the possibility of installing a hanging lock in each pair of aligned holes of the plates.

The implementation of the device in the form of two plates, forming a container for the keys of locks of the blockers and a means for locking the container with a padlock, provides a significantly smaller dimensions of the device than the dimensions of the known group boxes. The dimensions of the proposed device are commensurate with the dimensions of the multiplying overlay, which ensures the unification of the used auxiliary elements of the security blocking and information system.

Since the proposed device has dimensions similar to those of a multiplying overlay, one special device/workplace can be used to store such elements, which simplifies the operation of the auxiliary elements of the security interlock and information system.

In addition, such a device can be hung on the wall or stored, for example, in the pocket of the Permissive or in his desk drawer, which eliminates the need for a special place for its storage and simplifies its operation.

It is advisable that the bottom of the container on the first plate be formed by displacement in the first section of the plane of the first plate outward relative to the plane of its second section with the formation of internal protrusions forming three side walls of the container, while on the second plate, in the first section, an additional rim is made, forming the fourth side container wall

This implementation of the container is the most technologically advanced.

It is advisable that the container be made with the possibility of placing four keys in it, while at the bottom of the container two hooks are made with the possibility of placing two keys on each.

The presence in the container of hooks for the keys of locks of the blockers ensures their orderly storage.

It is expedient that on the first and second plates on the lid and the bottom of the container there are holes for viewing the key head.

The presence of such holes - windows allows you to identify the keys stored in the container without opening the container, which simplifies the operation of the device.

In the future, the proposed utility model will be disclosed in more detail on specific examples of its implementation with reference to the drawings, which show:

Fig. 1A-Fig. 1B - general view of the group blocking control device in the working position, from both sides;

Fig. 2 is a general view of the group blocking control device in an open form.

The group blocking control device during repair work of industrial equipment or its maintenance contains two plates: the first plate 1 (Fig. 1A, Fig. 2) and the second plate 2 (Fig. 1B, Fig. 2).

Plates 1 and 2 are connected to each other in the end part by a hinge 3 with the possibility of combining the plates with each other, as shown in Fig. 1A-Fig. 1B (working position of the device) and with the possibility of their radial displacement relative to each other, as shown in Fig. 2.

When plates 1 and 2 are aligned, on their first section 11 and 21 (Fig. 2) a container 4 (Fig. 1A) is formed for storing the key 5 (Fig. 2) from the blocker lock (not shown). In this case, the bottom 41 of the container 4 is made on the first plate 1, and the lid 42 of the container 4 is made on the second plate 2.

On the second section 12 and 22 of each plate 1 and 2, on opposite sides, a flange 13 and 23 is made, which is a bent side edge. Each specified flange 13 and 23 form a groove for the longitudinal lateral straight edge 14 and 24 of the opposite plate 1 and 2, respectively.

These flanges 13 and 23, which include the edges 14 and 24 of the opposite plates, ensure that the plates 1 and 2 are fixed relative to each other.

Also, on the second section 12, 22 of each plate 1 and 2, holes 15 and 25 are made, which are aligned when the plates are connected, as shown in Fig. 1A - Fig. 1B. When connecting plates 1 and 2, a padlock 6 of the blocker can be installed in each pair of holes 15 and 25.

The number of holes 15 and 25 in the device may be different depending on the industrial enterprise and the regulations for repair work.

The second portions 12 and 22 of the plates with rims 13 and 23 and holes 15 and 25 form means for locking the container with a padlock.

In the preferred embodiment shown in FIG. 1A and Fig. 2, the bottom 41 of the container on the first plate 1 is formed by shifting the plane of the plate 1 in the first section 11 outward relative to the plane of its second section 12 with the formation of internal protrusions forming three side walls 43, 44, 45 of the container 4. At the same time, on the second plate 2, on the first section 21, an additional lip 26 is made, forming the fourth side wall of the container 4. The side edge on the first section of the first plate enters into the additional rim.

In this case, it is possible that all side walls of the container 4 are made on the first plate, or two side walls of the container are formed by two flanges on the second plate.

Also in the preferred embodiment, the container 4 is configured to accommodate four keys. This condition determines the dimensions of container 4 and plates 1 and 2. In particular, the depth of the container, namely, the displacement of the first plate in the first section relative to the plane of the second section, as well as the width of the plates, are made based on the placement of four keys in it,

It is possible to make plates designed for a smaller number of keys.

At the same time, at the bottom 41 of the container, two hooks 7 are made with the possibility of placing two keys 5 on each.

The presence of hooks 7 allows the orderly storage of keys 5.

It is possible to make the container without hooks.

Also, in the preferred embodiment, on the first and second plates 1 and 2 on the lid 42 and the bottom 41 of the container, holes 16 and 27 are made to view the key head so that they can be identified when the device is closed.

However, it is possible to make plates without these holes.

The process of blocking and informing the LOTO system with the proposed device is carried out according to the well-known scheme as follows.

The duty officer, according to the work plan, prepares a workplace for the repair team: blocks the disconnected switching devices: installs the blocker on the blocking point, hangs a padlock on the blocker and the key 5 from the blocking lock is fixed on hook 7 at the bottom 41 of the device. While the plates 1 and 2 are radially offset relative to each other (Fig. 2).

A similar sequence of actions is performed with the following set blocking points. No more than four keys can be placed in one device. If more blocking points use the second device, etc.

When a given number of keys 5 is placed on the first plate 1, plates 1 and 2 are aligned with each other. At the same time, the longitudinal side edge 24 of the second plate 2 is inserted into the edge 13 of the first plate 1, and the edge 14 of the first plate 1 is inserted into the edge 23 of the second plate, and the side edge of the bottom 41 of the container 4 on the first plate 1 is inserted into the additional edge 26 of the second plate 2.

The admitting one installs the lock 6 in the combined pair of holes 15 and 25 and allows the workers to perform the work. The work manager, accompanied by a duty officer, checks the completeness of the preparatory measures and the readiness of the workplace. After making sure that the shutdown and blocking of the equipment is correct, the performers of the work hang their locks on another pair of holes 15 and 25 and start work.

The implementation of the device in the form of two plates, forming a container for the keys of locks of the blockers and a means for locking the container with a padlock, provides a significantly smaller dimensions of the device than the dimensions of the known group boxes. The dimensions of the proposed device are commensurate with the dimensions of the multiplying overlay, which ensures the unification of the used auxiliary elements of the security blocking and information system.

Since the proposed device has dimensions similar to those of a multiplying overlay, one special device/workplace can be used to store such elements, which simplifies the operation of the auxiliary elements of the security interlock and information system.

Such a device can be hung on a wall or stored, for example, in the pocket of the Permit or in his desk drawer, which eliminates the need for a special place for its storage, which simplifies its operation.

After the work is completed, the work supervisor reports to the duty officer on the completion of work and removes his security lock.

The admitting person makes sure that the work is completed, the workplace is cleaned and all participants in the work have left the work behavior area. Next, the admitting person removes his security lock 6 from holes 15, 25. Keys 5 from the blocking locks become available for unlocking with the subsequent transfer of equipment to operation or reserve.
