Description

[Detailed description of the invention] When controlling each element of engine rotational output and output transmission, zero triggering is a remote control system that allows both elements to be operated in series with each other from a position other than the fixed position of the driving operation. This relates to a control device.

Things that are equipped with an internal combustion engine #Ia etc. as the prime mover and whose eyes and bodies are linked by this output, such as ships and cars,
The mechanism that regulates the rotational output of the engine and transmits the output to the connecting means such as wheels or propellers is provided with a driver's cab or cockpit at the most suitable position for operation, and the operator is placed under normal pressure. It is located at a certain location and indirectly controls the speed regulation or output transmission of the engine and performs all operations.

In the case of general vehicles and aircraft, this type of operation cannot be performed unless the operator is located at a location away from the jammers, etc.; For work vehicles and ships equipped with a delivery force extraction mechanism,
A watchman is stationed at a predetermined position, and the operator performs indirect control from another suitable location away from the operator's cab, via the indirect control device in the operator's cab, or directly from outside the operator's cab. The entire output transmission mechanism can be controlled remotely,
It is widely used for its efficiency. In particular, in work vessels such as fishing vessels that operate in limited water areas, the main engine must continue to operate even during operations other than when the vessel is at sea. In addition to continuing the operation of the main engine, it is necessary to adjust the rotational output at any time as a working yl,
During Ik fishing, it is necessary to sail as the net is let out, or to move backwards and forwards at a slow speed as the net is unloaded, and during these times, most people other than the bridge watch, jk, and personnel are on duty to carry out each work on the bare area. It is necessary for most of the personnel to direct the surroundings of the fishing equipment, and at the same time to operate the ship in close and immediate response to each operation of the operation. A method to do so has been reported. [7] However, according to these methods, it became possible to reduce the rotational output due to the speed control of the main engine and to connect and disconnect the clutch that transmits this rotational output, but the speed control of the main engine and the clutch # There is no related element in both the FR engagement and operation questions, and if the clutch is replaced while the main engine's rotational output is increasing,
The main engine rotates at high speed without a driver, causing a so-called racing-like color, which may have an adverse effect on the main engine itself or other auxiliary equipment directly connected to it, or cause the clutch to undergo excessive reverse rotation when switching from 1st gear to reverse. There are concerns that the rotational torque will be applied and cause wear and tear on the clutch.

The present invention was developed in consideration of the current situation, and is attached to a manual indirect control head installed in a steering cab of a ship's bridge.
The clutch operating lever and the main engine speed regulating lever can be operated in the same way as manual operation, and the clutch operating lever and the main engine speed regulating lever can be operated remotely.
The aim is to establish a remote control system that maintains the relationship between the operations of both levers in the same way as in the case of manual handling, so that it will not have a negative effect on the L aircraft or the clutch, and it will be installed in a location isolated from the bridge. When controlling the clutch operation lever remotely, the main engine speed governor lever suppresses the injection of main engine fuel by its own weight, causing the main engine's rotational output to drop. The front and rear clutches are 9J.
Once you get used to it, clutch switching will always reduce the power of the aP+ injection in the main engine after the NFL, creating the behavior that occurs when the main engine's rotation speed is low. The purpose is to provide a remote control device for the main engine output system that has sufficient functionality.

Hereinafter, one example of implementation of the present invention will be described based on the drawings. Taking a small boat such as a fishing boat as an example, the internal engine output system is the engine 44 installed in the engine room, and the main engine speed governor lever +ll and clutch operating lever LI:ll of the 9111 control head installed in the bridge. is handled by. In other words, the main engine speed governor LSI! The rotational output is controlled by adjusting the fuel injection IT of the engine 4) through the control loop, and the control cable JL (l) is controlled by the clutch operating lever LJ field.
41 is operated to connect/disconnect the clutch or perform ltI reverse movement.

Therefore, in order to remotely control the indirect control head from the vicinity of the fishing equipment isolated from the vessel, an IT-operated remote driver (8) is installed, and a cable with an appropriate level of heat is used to remotely control the indirect control head (1). ), the above remote driver +8
) Connect K. The remote control controller (11) has a small and portable shape, and is equipped with a steering knob (2), an earth speed control knob (3), and a clutch knob (4). A relay distributor (6) is interposed between the remote driver (8) and the remote driver (8).In addition to the wiring from the relay distributor +61 to the remote driver +8), the steering amplifier/6
) and operates the steering knob (2) of the remote control controller (1), an electrical signal is sent from the relay distributor (6) and reaches the solenoid pulp of the hydraulic system on the steering side. , (p1
The rudder angle can be set by the rudder.

As shown in Figure 2, the remote driver 8) is equipped with a main engine speed governor control mechanism that controls the main motor and a clutch control mechanism that controls the first auxiliary motor. 6 Hanging 1] The control mechanism (/: 1. Each has a rotating shaft and is protruded from the casing of the remote driver; 8), and the shaft protrusion of the main engine speed regulating mechanism is connected to the In addition, clutch arms 11'4 are housed in the shaft protruding parts of the clutch system 4 and the clutch system 4, respectively, and the tip of the main engine 1i 1 series arm (9) and the speed control lever 111 are connected to each other. In addition, the tip of the clutch arm Ufi and the clutch operating lever 1 are each connected by a transmission element such as a control group 41m + 101, and each drive of the main engine speed governor control mechanism or the clutch control MA mechanism 4 is connected. By rotation #11 of the shaft based on the motor, the main engine speed regulating arm (9) or clutch arm v2 performs an oscillating motion, and the main engine speed regulating arm (9) or clutch arm of the indirect control head is operated via the control cable 1q. The lever Jl can be raised and lowered in the forward and backward directions.

These drive motors c! To rotate 4-, use a storage battery installed in the ship as a power source (7), and connect the relay distributor ill.
Connect wiring to the terminal board Gtυ of the K IJ motor driver 18). Wire from the terminal plate υ to the main engine speed governor side circuit (2), which includes the drive motor of the main engine speed governor mechanism (a), and the clutch operation side circuit wr@, which includes the drive motor of the clutch control mechanism (to). Format the network.

By doing this, by rotating the main engine speed governor knob (3) of the remote control device (1) connected to the relay distributor (6) with a cable of an appropriate length and located at a distance from the bridge, The electrical signal sent from the relay distribution @III to the main engine speed control side circuit (2) via the terminal board @rotates the drive motor by a predetermined amount in the desired direction, and Speed control #mechanism 4 main 1m speed control arm, 91iC
3i Swinging alligator is caused, and the tip of the arm and the main engine speed control lever Ill! The main engine speed regulating lever on the bridge is connected via the control couple provided between the 11! The engine's fuel injection jet is arbitrarily selected by raising and lowering the -E speed control bar, and the engine's rotational output is smoothly controlled. It is.

In addition, the remote IT, 11 m controller TLL clutch knob Otori 4) can be set to forward (F), reverse (R), and g, which are different from the current situation.
If set to neutral (0) K, the electric gL signal sent from the relay distributor (6) to the circuit 1β on the Kuratuna operating side via the terminal board will rotate the drive motor the required amount in the specified direction. This causes the force of the clutch arm II of the clutch control mechanism that is continuously operated to generate fi1' dispersion movement, and the clutch on the bridge is activated via the control couple provided at the tip of the arm and the clutch operating lever lJ4. It performs the same previous operation as manually operating the operating lever J:1, and not only can the clutch operating lever be operated in forward, reverse, or neutral position to move the boat astern or Vi drifting, but also to operate the clutch half way. It can also be used as a clutch to freely move forward and backward at very low speeds.

However, when maneuvering the ship alongside the husband, only the speed control of the main engine is required.
Alternatively, it is very rare to operate each clutch independently, and especially in bare areas of fishing grounds, the fishing boat must perform various operations to follow the fishing operation.
As a result, there are many operating methods in which the speed control of the main engine and the clutch operation are performed simultaneously using the palm of the hand. In some cases, in the device of the present invention, the remote driver 1
8) A reset circuit is built into the main engine speed control side circuit installed in the main engine speed control side circuit and is also connected to the clutch operation side circuit (2).This reset circuit 4 consists of a bridge and a relay, and is controlled by remote control. When the clutch knob (4) of the controller +1) is operated, an electric signal is received from the clutch sweeping side circuit (b), and this reset circuit controls the main m governor side (b) path (2). It functions to operate the drive motor, and the main engine speed governor side circuit (c) and the main engine speed governor l1I
Regardless of the change in the operation of the main engine, the J organization (to)
Immediately and automatically the main*II continuous arm (9) (naturally the main 8
The m# prefectural lever (■) also has a rotational output of low current w1
Unfortunately, while the synchronized output was at a low position, the clutch knob (4) was operated, and after a while, the main engine speed governor arm +9) returned to its original position of 7ft, turning #L, and the engine (b) Transmission power is reset.

In other words, clutch! Thl! The main engine regulating side and the clutch side can be completely integrated by installing it in the main engine regulating side circuit F13 in connection with the actuating side circuit (2) or by using a serator circuit.
When the clutch is disengaged or engaged, even if the engine speed is rising, the engine speed is automatically lowered to slow speed, and the engine speed is automatically restored to the original speed as soon as the clutch operation is completed.

In the remote control system of this invention, remote control system +1
