UA74950C2 - Body of the railroad open freight car with a solid bottom - Google Patents

Abstract

Invention relates to the railroad car construction. The body of railroad open freight car with solid bottom contains a frame, which includes a center girder, coupling and cross beams connected by angle type lower link with side walls consisting of upright posts. The latter are rigidly connected with the cross beams on the bottom by trapezoid cover plate with openings for drain of water from said posts, and from above - by junction box having trapezoidal form in the plan. Cross beams are of channel type and at junction with the lateral posts areclosed with vertical plates in the box-frame structure. Between the cross beams, in parallel to central girder are rigidly fastened the angle type power profiles with formation of lattice type power bottom. Invention allows to decrease the metal content of the carriers of body with increase of strength of its bottom.

Description

Description of the invention

The invention relates to railway transport, in particular, semi-car constructions with a dead floor. 2 Well-known bodies of half-cars with a dead floor, resting on a frame, containing spinal, pivot and transverse beams, rigidly connected with side straps, to which the side walls are locked, supported by vertical racks of the box or channel type. These include a half-car with a hollow body for the transportation of bulk cargo, model 12-197 developed by Uralvagonzavod | see the prospectus of the "Izdeliya rolling stock" plant, published in the Russian Federation in the city of Nizhny Tagil, Sverdlovsk Region, East Highway, 28), as well as information about 70 cars can be obtained at pEr://Lymlu.cm2.gy/. The car is designed for the transportation of bulk non-aggressive cargo that does not require protection from atmospheric precipitation, bulk non-dust-like bulk cargo with unloading on a wagon dumper, with a temperature not higher than 1002С, operated on roads with a gauge of 1520 mm, at low temperatures - 6026.

Among the disadvantages of the analogue, it is worth mentioning that the car has a large weight due to the use of the box-type t5 side skin of the frame, as well as the large thicknesses of the bottom and sidewalls.

The well-known "Semi-wagon body with a dead floor", the design of which is protected by copyright Mo 196079,

IPC В 61 О 17/04, Mo application 947632/27-11, published in the Mo 11 bulletin dated 06.1967. The body of a semi-wagon with a dead floor, resting on a frame that includes pivots and transverse beams, connected by a lower strap with side walls consisting of racks with overlays and sheathing, while the lower strapping is made of trough-shaped profile material and is rigidly connected to the pivot and transverse beams of the frame, as well as rack overlays using box elements.

Among the disadvantages of the analogue is the fact that the volume of the body decreases, and the presence of box elements on the bottom reduces the corrosion resistance of the body.

The prototype of the invention is the "Railway Car Body", the design of which is protected by the copyright certificate No. 29 Mo1239008, 861017/00, Mo application 3667113/27-11, published in the Mo 23 bulletin dated 06/23/86, Go)

The body of a railway car with a dead floor, protected by the author's certificate Mo 1239008, rests on a frame that includes spinal, pivot and transverse beams, connected by a bottom strap of the angle type to the side and end walls, consisting of vertical struts that protrude behind sheathing to the height of the transverse beams and interconnected below by a connecting box, which has a trapezoidal shape in plan, with upper and lower shelves, while, in order to increase strength, the upper shelf is located obliquely up to IV) side wall and rigidly attached by its edge to the last one. The side walls of the body are equipped with a lower corner strap and vertical box struts, which are rigidly connected to the box transverse beams of the F frame, placed between the pivot beams. For their connection, trapezoidal linings are used, "And they are equipped with holes for water drainage from the vertical box-shaped racks of the side walls. The flow of water 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 main shortcomings of the prototype. They should also include the excess weight of the body, which arose due to the increase in the thickness of the bottom, because the design of the body does not ensure the perception of loads of torsional vibrations.

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

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 backbone beam of the frame and the lower corner straps of the side walls, and secondly, the transverse beams of the frame are made of channel type, to to which longitudinal beams of the angular 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 transformed into a box structure, available for painting after welding. -1 15 The technical result achieved by the invention is that with the introduction of additional elements of stiffness 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, the use of transverse beams of the channel-type frame increases the durability of its operation, because it provides the possibility of its maintenance, that is, painting of places subject to corrosion. 1 20 The essence of the invention is explained by the drawings, where: o in fig. 1 shows the body of a semi-wagon, general view; in fig. 2 - section A-A in fig. 1; in fig. C - the same, top view; in fig. 4 - the same, side view; in fig. 5 - cross section of the bottom of the body;

GF) in fig. 6 - section B-B in fig. 5; 7 in fig. 7 - joint of bottom sheets (plan).

The body of a railway semi-car with a dead floor contains side walls 1 (Fig. 1) with struts 2 and lower ties 3. Wall 1 is connected to transverse beams 4 (Fig. 2) by means of connecting boxes 60 consisting of side walls 5 and upper shelf b. At the bottom, the racks 2 are connected to the transverse beams 4 with overlays 7. The side walls 5 of the connecting box are divergent (Fig. C; 4), and the upper shelf 6 is located obliquely and connects the upper part of the vertical shelf of the lower strapping 3, which is in the embedment zone with the upper sheet of transverse beam 4. This design increases the embedment depth of rack 2 without changing the dimensions of the frame and side walls 1. Increasing the embedment depth of rack 2 increases the strength of the connection of the side walls 1 of the bo body with the wagon frame. The open end of the rack 2 is fastened to the transverse beam 4 with a pad 7 equipped with holes for draining water.

The bottom of the body is equipped with a spinal beam 8 (Fig. 5), pivot and transverse 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 with racks 2 rigidly fixed power profiles of the angular type 9, which form the power bottom of the lattice type. Transverse beams 4 are made of channel type, and in the places of connection with side racks 2 under boxes 5 and 6, closed with plates 10, in a box structure (Fig. 6), available for painting the inner surface after welding, which prevents 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. In the locations of the box brackets 7/0..5 16, they are made with an overhang on the trapezoidal base 12.

According to this technical solution, design and technological documentation was developed at OJSC "KBBZ" and a test sample was produced, which is undergoing testing.
