Abstract

FIELD: railway transport.

SUBSTANCE: proposed blind-bottom open-top car running parts, frame with body. Cantilever parts of center sill 17 are made up to level of bolsters 3 to which automatic couplers 5 transmit load. Tops of first pair of V-shaped struts 18 start in places of connection of cantilever parts of center sill 17 with lower binding of end face walls, and bases of struts are arranged in places of connection of bolsters with binding of frame. Tops of second pair of V-shaped struts 19 are arranged at reverse side of bolsters and they rest of central parts of central sills, and their bases rest on places of connection of cross beams with frame binding, thus protecting bolsters from loads which cause side bending. Lower thickened sheets of sides play the part of frame binding closed and end faces by lower binding of end face wall.

EFFECT: increased capacity of body and reduced weight of body.

Description

The invention relates to railway transport, and in particular to freight cars intended for the transport of bulk non-aggressive cargo that does not require protection from atmospheric precipitation, the cargo should be lumpy, non-dusty, and unloading should be carried out by turning the car on a tipper.

Known deep-sea gondola, the body of which is protected by the USSR copyright certificate No. 196079, IPC B 61 D 17/04, application No. 947632 / 27-11, bulletin No. 11 of 30.06.67. A similar gondola car includes a frame equipped with a spinal and two pivot beams with seats for biaxial carts. The side frame trim is made of trough-shaped core material. It is rigidly connected to the sidewalls and the transverse frame set.

The disadvantages of the analogue include the fact that its body structure is heavier due to the presence of a spinal beam and box-shaped elements connecting the vertical struts to the frame.

As a prototype of the invention, a railway gondola car, protected by RF patent No. 2137637, B 61 D 17/04, application No. 98108947/28 of 04/13/98, bulletin No. 26 of 09/20/99, was adopted.

The invention protects the body of a gondola car equipped with a rounded bottom.

The prototype contains running gears - biaxial bogies, a frame with pivot, cross beams, cantilever parts of the spinal beam with automatic coupled devices in them, a body mounted on the frame, including side and end walls, the frames of which are rigidly connected to the frame trim, have side and corner racks and a box-shaped upper strapping rigidly connected to the side angular racks, made in the form of pairwise arranged plates, have the form of intermediate trapezoids, the vertical sides of which are interconnected by elem stiffeners, and the inclined sides in the lower part are equipped with ledges with the transition of the latter into protruding elements congruent to the rounded part of the body. A spinal beam is fixed along the axis of the frame, to which pivot and transverse beams are attached.

The presence of a spinal beam complicates the design of the gondola car frame, and the inclination of the sidewalls reduces the volume of the body, which, along with the complexity of manufacturing parts, can be attributed to the disadvantages of the prototype.

The purpose of the invention is, firstly, to increase the volume of the body, secondly, to reduce its weight, and thirdly, to simplify the design of parts for building the body.

This goal is achieved, firstly, by making the body rectangular, without rounded corner joints of the bottom with the sidewalls, secondly, by eliminating the spinal beam in the area between the pivot beams, thirdly, the details of the sidewalls are made in the form of rectangular sheets of different thicknesses, with thicker along the sides at the junction with the bottom, to the level of the transverse set of the frame.

The essence of the invention lies in the fact that the cantilever parts of the spinal beam are supported by two V-shaped struts, in which the vertices of the first pair originate at the junction of the cantilever parts of the spinal beams with the lower trim of the end walls, the base at the junctions of the pivot beams with the side trim of the frame, and the tops of the second pair of V-shaped struts located on the back of the pivot beams rest on the central parts of the pivot beams, the bases on the junction of the transverse beams with the frame trim, protecting ornevye beams from bending loads on the side. The frame design contains only the cantilever parts of the spinal beam, made up to the level of the pivot beams, with automatic couplers placed in them that transfer the load to the pivot beams.

The lower thickened sheets of the sidewalls perform the function of strapping the frame, closed at the ends of the lower strapping of the end wall, made of a thickened sheet connected to the pivot beams by inclined braces from the axis of attachment of the end part of the spinal beams, to the strapping of the frame at the junction with the pivot beams. In order to turn on the upper box of the body for the perception of longitudinal loads by the gondola car from the outside of the side walls of the body, from the pivot beams to the first vertical struts of the side walls at the places of their connection with the box body strapping, four inclined struts are attached to shape the semi-trusses to the side of the body.

The technical result of the invention lies in the fact that the volume of the gondola car body increases while reducing its weight and simplifying the design of its parts and assemblies.

Improving the technical characteristics of the car, in turn, has a positive effect on reducing the cost of the product.

The invention is illustrated by drawings, where:

figure 1 shows a General view of a deep-sea gondola car

(side projection);

figure 2 is an end view;

figure 3 is a view of the underbody;

figure 4 is a cross section of a body.

The deep-sea gondola contains a running gear 1 (Fig. 1) articulated with a frame 2 equipped with pivot beams 3, transverse beams 4 and an automatic coupler 5. A body 6, sidewalls 7, which are equipped with vertical struts 8, sheet 9, box top, are mounted on frame 2 strapping 10 and inclined racks 11, forming a half-farm of the sidewalls 7 of the body 6, based on pivot beams 3 for the perception of longitudinal loads. The end part of the deep-wagon gondola car is equipped with an end sheet 12 (Fig. 2), a lower strapping of the end wall 13 and a set of stiffeners 14 and 15. The frame 2 contains a bottom 16 (Fig. 3) and cantilever parts of the spinal beam 17, made up to the level of the pivot beams 3 , with automatic couplers 5 placed therein, transferring the load to the pivot beams. To reduce the loads bending the pivot beam 3, the cantilever parts of the spinal beam are supported by two V-shaped struts 18 and 19, at which the vertices of the first pair originate at the junctions of the cantilever parts of the spinal beam 17 with the lower trim of the end walls 13, and the base in places the connection of the pivot beams 3 with the lower thickened sheets of the sidewalls 20, while the vertices of the second pair of V-shaped struts 19 located on the back side of the pivot beams 3 are based on the central parts of the pivot beams, and the bases on the junction crossbeams 4 with strapping frame, protecting the bolster of the loads on the lateral bending. The lower thickened sheets of the sidewalls 20 (Fig. 4) perform the function of strapping the frame closed at the ends of the lower strapping of the end wall, made of plate steel, mainly of strip, providing T-joints with the bottom 16 and not protruding beyond the plane of the bottom sheet of the pivot beams. The dimensions of the strip are determined by calculation.

Assembly is as follows. The frame is welded, then the sidewalls and end walls of the body are welded to it. Installation of automatic couplers is carried out in the order established by the technological process.

Unloading a gondola car is carried out using a tipper.

The use of the invention provides the creation of a deep-sea gondola car of a simplified design, provides the simplicity of parts and an extended service life.
