Description

The utility model relates to railway transport, mainly to universal universal gondola cars with hatches in the floor of the body and relates to the structural design of the frame, in particular its pivot beams that connect to the frame and the body and interact with the manhole covers. The proposed utility model can be used by car-building enterprises in the production of universal hatch gondola cars.

In the CIS countries, Georgia and in the East Baltic countries, pivot beams of the hatch gondola car frame [1], consisting of two pairs of vertical walls, as well as the lower and upper shelves that overlap the vertical walls and the spinal beam of the frame, are widespread and widely known from the prior art. . At the same time, the lower shelf is made tapering from a friday place, on the vertical walls and the upper shelf there are compensation pads for welding joints with bearing elements of the gondola car. The lateral edges of the upper shelf are designed to interact with closed manhole covers, i.e. to seal the gaps between the covers and frame elements. Known pivot beams [1] include plate top shelves made with a medium convex corrugation, which is reinforced from below (inside the beam) by a longitudinal welded insert and serves as a transverse base for placing long loads, as well as bulges on the hatch cross beams of the frame.

Also known is the pivot beam of the hatch gondola car frame [2], which contains a flat plate top shelf of the same purpose, which is reinforced from above with a welded stamped or bent element and has shaped stamped compensation lining for welding joints with bearing elements of the gondola car - lower strapping of the side walls of the body.

The disadvantages of the known design of the pivot beam of the frame [1] is the increased material consumption in the manufacture and welded reinforcement of the upper plate shelf, as well as the need for heavy press equipment for stamping corrugations. The well-known pivot beam of the gondola car frame [2] also has increased material consumption and labor costs for performing welding work to strengthen the pivot beam with upper welded elements and a set of shaped stamped compensation pads (two per connection). At the same time, the known pivot beams [1 and 2] also have a drawback in operation - under the flat lateral edges of the upper shelf, when closing the manhole covers, the remains of wet bulk cargo accumulate and compress, which leads to rapid corrosion, deformation and damage to the edges of the manhole covers and upper shelves of pivot beams. Bulk cargo remains after unloading and on flat sections of the upper shelves of pivot beams.

The objective of the proposed utility model is the structural and technological improvement of the pivot beams of the frame in order to reduce the cost of their manufacture in serial production of open wagons, without using heavy press equipment for the manufacture of parts, with an improvement in the functional purpose of the structure in operation.

The technical result of the proposed utility model is the reduction of material and labor costs in the serial production of pivot beams of the gondola car frame, ensuring the manufacture of parts of these assembly units on universal equipment and increasing operational reliability.

To achieve a technical result, in the pivot beam of the hatch wagon frame, which includes two pairs of vertical walls, the lower and upper shelves that overlap the vertical walls and the spinal beam of the frame, while the lower shelf is made tapering from the pyatnik place, and on the vertical walls and the upper Compensation plates for welding joints with supporting elements of the gondola car are installed on the shelf, and the lateral edges of the upper shelf are designed to interact with closed manhole covers, the upper shelf is double hydrochloric, folded-over along the axis of symmetry of the items, and the vertical walls raised in height to contact with the gable top shelf and formed with rectangular cutouts for welding connections with elements gondola car body. At the same time, the compensation pads installed on the upper gable flange repeat the cross-section of the shape of the latter and are double beveled at the end to improve the welding connection with the upper gable flange, and the lateral edges of this flange interact with the working surfaces of the closed manhole covers along the generatrix lines of the lower edges . The upper gable flange can be made of two parts of equal length, which are joined together on a permanent lining, welded from below and repeating the shape of the upper gable flange.

Such a structural and technological implementation of the pivot beam of the hatch wagon frame reduces the cost of the product and improves its operational properties.

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

The pivot beam of the hatch wagon frame, Figs. 1, 2, and 3, is mounted on the spinal beam of the frame (shown by a dashed line in the drawings) and consists of two pairs of vertical walls 1 connected by diaphragms 2, the lower shelf 3 and the upper shelf 4. Recent overlap the vertical walls 1 in pairs and the spinal beam of the frame. The vertical walls 1 are additionally connected to the spinal beam by compensating plates 5, which are a continuation of the vertical walls 1. The lower shelf 3 narrows from the spot Pyatnikovy B, it is equipped with side bearings B, designed to interact with the sidecar of the gondola carriage. The upper shelf 4 is gable, i.e. bent along the axis of symmetry of the part, has sloping edges G and is welded with both pairs of vertical walls 1 and plates 5. The height of the walls 1 is increased to contact with the upper gable flange 4, and rectangular cutouts D are made in the upper parts of the vertical walls, providing welding connections with elements body - lower longitudinal strapping E of the side walls. At the same time, on the upper gable flange 4, connecting compensation slips 6 are installed, which repeat in cross section the shape of the upper gable flange, are adjacent to the last and lower longitudinal strapping E. The lining 6 is made with double bevels Ж at the end, designed to improve welded joints with the upper gable shelf 4. The sloping lateral edges of the latter interact with the working surfaces of the closed manhole covers along the generatrix lines K of the lower edges, which does not create conditions for pressing loose residues cargo. The upper gable flange 4 can be made of two equal parts in length, which are joined together on a permanent lining 7, welded from below and in cross section also repeating the shape of the upper gable flange.

When the gondola car frame is in the normal position, two pivot beams, without lower shelves 3 and connecting compensation plates 5 and 6, are mounted on the spine beam, which is placed on the pre-installed lower shelves 3, and welded to the latter. Then the plates 5 are installed. The plates 6 are installed and welded to the upper gable flange 4 when the frame is connected to the side walls of the body and perform their functions. The installation of the proposed pivot beam in the frame is also possible with the collector frame of the gondola car in an inverted position, i.e. with a different technological scheme for assembling the frame.

In operation, when unloading gondola cars through hatches, bulk cargo does not linger on the sloping surfaces of the gable upper shelves of 4 pivot beams. The accumulated residues of wet bulk cargo, at the edges of the manhole covers, are cut by the lower edges of the gable shelves along the generatrix lines K (Fig. 3), while the cargo remains are not compressed, but are cut by the edges when the manhole covers are completely closed.

The applicant enterprise, as part of the projects of gondola cars of models 12-9933 and 12-9933-01, developed the working drawings of the improved pivot beam proposed as a utility model. Samples of gondola cars of models 12-9933 and 12-9933-01 are made with the proposed pivot beams and undergo strength tests. With 1 sq. In 2013, it is planned to mass-produce them at PJSC Diesel Plant.
