Description

The utility model relates to railway transport, in particular, to universal universal gondola cars with hatches in the floor of the body and relates to the design of the beam diameter at the places of their interfacing with the manhole covers and joints with the body walls. The proposed utility model can be used in serial production of universal gondola cars with hatches in the floor of the body of all sizes and with their overhaul.

In the CIS and Baltic countries, four-axle all-metal open wagons [1] with hatches in the body floor have become widespread and widely known in the art. The structure of the famous open wagon frame includes four interhatch (intermediate) transverse beams, each welded from vertical sheets and horizontal shelves - lower and upper. The upper horizontal shelf is made in the form

flat plate and is the overlapping (sealing) element of the manhole covers that are adjacent to these plates from the bottom. The latter are sufficient, in accordance with the interstate standard [2], to seal manhole covers for new cars, but, during operation, under the influence of the rest of the load pressed on the edges of the covers and under the shelves, the latter are deformed, and the seals of the manhole covers are broken. At the same time, not only seals are violated, but there is also the possibility of “scoring” and damage to the shelves of the overlapping plates as a result of unloading of universal open wagons with a grab. This is a significant operational drawback, since it is quite difficult to reduce the damaged gaps between the hatch covers and frame elements and repair damaged upper belts of the hatch cross beams under operating conditions. Also known are the intermediate (hatch) transverse beams [3] of the I-section, also welded from vertical sheets and two horizontal belts, the upper belt of which is made with a central convex corrugation or with a welded, semicircular section reinforcing element. The upper belt is connected to the walls of the body with the help of scarves and stamped compensating pads. However, the reinforcement of the upper belt does not eliminate the above operational disadvantage of the known design of girder beams [1], but only increases the complexity of its manufacture. In addition, in the horizontal sections of the upper zones, the remains of bulk cargo are delayed, which must be removed manually.

The objective of the proposed utility model of the frame is to improve the design of the hatch (intermediate) transverse beams, aimed at increasing operational reliability, better dumping of goods and improving the manufacturability of manufacturing universal gondola cars. The technical result is significant

reduction of damage to the transverse hatch beams and a decrease in cargo residues in the body when using gondola cars as universal ones, as well as a decrease in the complexity of manufacturing beams due to structural changes in the elements protruding into the body.

To achieve the task, in the proposed inter-hatch cross beam, including vertical walls welded with lower belts and upper belt, the last of which seals manhole covers, and containing compensating pads for connection with body walls, the upper belt of the beam is made in the form of gable shelves, designed for interacting with the surfaces of manhole covers along the generatrix lines of the lower edges of the shelves and dumping of cargo. At the same time, on the vertical walls of the beam, under the gable shelves, local reinforcing elements are installed, and compensating overlays in the cross section repeat the shape of the gable bent shelves, moreover, one end of the overlays is made with a double bevel to improve welding to the belt. The local reinforcing elements of the gable shelves are made of an L-shaped section and additionally connect each inclined shelf of the upper zones with vertical walls.

Brief Description of the Drawings

Implementation of a utility model (device and principle of operation)

The hatch cross beam according to the proposed utility model consists of two vertical walls 1, FIGS. 1, 2, 3, covering the spinal beam “B” of the gondola car, inserts 2, which serve as a continuation of the vertical walls 1 in the middle part, and welded with vertical walls of the two lower belts 3 and the upper zone 4. The lower zones 3 are located on both sides of the spinal beam. The upper belt 4, being part of the load-bearing transverse beam, seals manhole covers (not shown in the drawings) with its shelves “B” by interacting with them along the generatrix lines of the lower edges “G”. The upper belt 4 is made in the form of gable curved shelves to ensure interaction with the surfaces of the lids not along the plane, but along the generatrix lines of the lower edges “G”. The latter eliminates the possibility of “pressing” the cargo residues in the sealed areas during operation, provides loosening of the cargo residues with the sharp edge “G” and the fit of the covers to the sealing upper belt 4 of the beam. To increase operational reliability on the vertical walls 1, under the gable bent shelves "B", local reinforcing elements 5 are made, made of an L-shaped section, which additionally connect the shelves "B" of the upper belt 4 with the vertical walls 1 and provide the belt with stability in operation when unloading with a grab. On the vertical walls 1 are also installed curved brackets 6 and 7, right and left versions, to hold the manhole covers in an open inclined position, made by hot stamping. The upper belt 4 is connected to the side walls of the body by compensating pads 8, which are also gable, as well as the belt 4. The compensating pads 8 are welded to the latter along the “D” bevels.

The applicant company has developed working drawings of the frame and body of a promising universal gondola car model 12-9791

(with an axle load of 25 tons) using the proposed inter-hatch cross beam. Prototype gondola cars of this model will be manufactured and presented for testing in May 2008. At the same time, design and technological documentation is being developed for using the proposed utility model in the production of serial universal gondola cars of model 12-9790.
