Abstract

FIELD: railway transport.

SUBSTANCE: proposed body of rail gondola car with blind floor rests on frame including center sill, bolsters and cross beams connected by angle type lower binding with side walls consisting of vertical uprights projecting from skin by height of cross beams and coupled at bottom with cross beams by cover with holes to drain water from vertical uprights. Side wall is connected with cross beams by connecting boxes with diverging side walls and upper flange arranged with tilting upwards to side wall and rigidly connected by its edge to side wall. According to invention, channel cross beams of frame are closed in places of connection with side uprights by vertical plates to form box structure accessible for painting of inner surface after welding. Angle-type load bearing sections are rigidly secured between cross beams connecting them parallel to center sill and forming load-bearing bottom of lattice type.

EFFECT: increased rigidity and strength at reduction of weight by decreasing thickness of sheets.

Description

The invention relates to railway transport, in particular to the construction of open wagons with a deaf floor.

The body of open wagons with a deaf floor, based on a frame, which includes spinal, pivot and transverse beams, rigidly connected with side harnesses, on which side walls are closed, reinforced by vertical struts of the box or channel type are known. These include a dead-body gondola for transportation of bulk cargoes of model 12-197 developed by the Uralvagonzavod (see the prospectus of the Product of Rolling Stock Factory of the Russian Federation, published in Nizhny Tagil, Sverdlovsk Region, Vostochnoye Shosse, 28), (http: / /www.uvz.ru/). The wagon is designed for transportation of bulk non-aggressive cargoes that do not require protection from precipitation, bulk non-dusty bulk cargo with unloading on a tipper car, with a temperature of not higher than 100 ° C, operated on 1520 mm gauge roads, at low temperatures - 60 ° C.

The disadvantages of the analogue include the fact that the car is heavier due to the use of the side sheathing of the box-type frame, as well as the large thickness of the sheet metal of the bottom and sidewalls.

The famous "Gondola car with a deaf floor", the design of which is protected by copyright certificate No. 196079, IPC B 61 D 17/04, application No. 947632 / 27-11, published in bulletin No. 11 of 06.1967, Gondola car body with a deaf floor, based on the frame, including the pivot and cross beams, is connected by the lower harness to the side walls consisting of struts with overlays and sheathing, while the lower harness is made of trough-shaped profile material and is rigidly connected to the pivot and transverse beams of the frame, as well as the struts of the racks using short batey elements.

The disadvantages of the analogue include the fact that the volume of the body is reduced, and the presence of box-shaped elements on the bottom reduces the corrosion resistance of the body.

The prototype of the invention is the “Railroad car body", the design of which is protected by copyright certificate No. 1239008, B 61 D17 / 00, application No. 3667113 / 27-11, published in bulletin No. 23 of 06.23.86.

The body of a railroad car with a deaf floor, protected by copyright certificate No. 1239008, is supported by a frame including spinal, pivot and transverse beams connected by a lower corner-type trim with side and end walls consisting of vertical struts that protrude beyond the skin to the height of the transverse beams and connected between each other with a lower junction box, having a trapezoidal plan, with upper and lower shelves, while in order to increase strength, the upper shelf is sloped upward to the side wall fixedly attached end to the last. The side walls of the body are equipped with a lower corner harness and vertical box-shaped struts, which are rigidly connected to the box-shaped transverse beams of the frame located between the pivot beams. To connect them, trapezoidal linings are used, equipped with holes for draining water from the vertical box-shaped racks of the sidewalls. Water flow from the box-shaped transverse beams of the frame is difficult, as a result of which they are exposed to corrosion, which should be attributed to the disadvantages of the prototype. They should also include overweight on the body by increasing the thickness of the bottom, because body structure does not provide perception of torsional vibration loads.

The aim of the invention is, firstly, to increase the strength of the body without increasing its weight, and secondly, to eliminate the influence of corrosion of the power beams of the frame on its destruction during operation.

This goal is achieved by the fact that, firstly, the bottom of the car body is reinforced with longitudinal beams of the corner type, placed in pairs between the spinal beam of the frame and the lower corner strapping of the side walls, and secondly, the transverse beams of the frame are made of the channel type, to which the longitudinal beams of the corner type are fixed . At the junctions of the transverse beams of the frame with the vertical struts of the sidewalls, the transverse beams of the channel type are converted into a box section, which is available for painting after welding.

The technical result achieved by the invention is that with the introduction of additional elements of rigidity and strength of the bottom of the car body, it is possible to reduce its weight by reducing the thickness of the sheets.

In addition, by performing the cross beams of the channel type frame, the durability of the operation of the body increases, because the possibility of its maintenance is provided, i.e. coloring of places subject to corrosion.

The invention is illustrated by drawings, where:

Fig.7 is a joint of sheets of the bottom (plan).

The body of a railway open wagon with a deaf floor includes side walls 1 (Fig. 1) with struts 2 and lower harnesses 3. Wall 1 is connected to the transverse beams 4 (Fig. 2) via junction boxes consisting of side walls 5 and the upper shelf 6 The bottom of the rack 2 is connected to the transverse beams 4 by the plates 7. The side walls 5 of the junction box are made diverging (Fig. 3; 4), and the upper shelf 6 is inclined and connects the upper part of the vertical shelf of the lower trim 3, located in the embedment zone, with the upper sheet transversely beam 4. This construction increases the depth of embedment rack 2 without changing the dimensions of the frame and side walls 1. Increasing the depth increases the sealing pillar 2 bond strength the side walls of the body 1 with the frame of the car. The open end face of the rack 2 is fastened to the transverse beam 4 by a cover 7 equipped with holes for draining the water.

The bottom of the body is equipped with a spinal beam 8 (Fig. 5), pivot and cross beams 4 connected to the side struts 2. Between the transverse beams 4, connecting them parallel to the spinal beam 8, in pairs, at equal distances between it and the side struts 2 are rigidly fixed power profiles of angular type 9, forming a power lattice type bottom. Cross beams 4 are made of channel type, and at the junction with side posts 2 under junction boxes consisting of side walls 5 and upper shelf 6, they are covered with plates 10, in a box-shaped structure (Fig. 6), which is available for painting the inner surface after welding, which protects it from corrosion. The bottom of the body is made of split sheets 11 (Fig. 7), the joint of which is placed above the transverse beam 4. At the locations of the junction boxes, consisting of side walls 5 and the upper shelf 6, they overlap on the trapezoidal base 12.

The protected body structure was developed at OJSC KVSZ and a prototype was made on it, which is being tested for strength. Car index 12-7019.
