Description

The proposed utility model relates to railway transport, namely, to the designs of gondola cars with a deaf body.

There are known designs of gondola cars with a dead body of model 12-1592, gondola cars for copper ore model 12-4024, cars for bulk metallurgical goods (model 22-4008) [1], gondola cars for inert bulk cargoes of model 12-295 [2], gondola cars for inert bulk non-dusty bulk cargoes of model 12-2104 [3], open wagons with a dead body of models 12-9833, 12-9833-01, 12-9869 [4] for transportation of goods that do not require protection against atmospheric precipitation, bulk, non-dusty , bulk and tare-piece, the body design of the gondola according to the patent [8].

The listed models of open wagons include chassis (trolleys) typical for freight cars, braking equipment, an automatic coupler and a welded-structure body consisting of two side walls, two end walls and a frame with flooring. The frame includes a longitudinal spinal beam, transverse beams (end, pivot, intermediate), additional longitudinal beams supporting the flooring. The end beams of the frame are welded or stamped with an L-shaped cross section. The pivot and intermediate beams are welded box or T-section and include one or two vertical sheets and two belts: the upper and lower. The upper belts of the pivot and intermediate beams are flat of sheets or strips, or of a special profile used in the design of the frame of universal gondola cars with hatches. The upper belts of all transverse beams intersect the spinal beam and form lap joints with the upper shelves of the spinal beam profiles. The sheets of the floor with longitudinal edges are connected with the upper shelves of the profiles of the spinal beam and the lower side trim, and transverse with the upper belts of the transverse beams. Compounds are also lapped. The gondola car body according to the patent [8] has convex end walls and a zigzag design of the upper belts of the transverse beams. The listed wagons are intended mainly for unloading on tippers and the cargo in them is placed in the volume formed by the side and end walls and the floor installed on the upper plane of the frame.

These designs of gondola cars have the following disadvantages:

- in gondola cars with flooring on the upper plane of the frame, the carriage is not used to accommodate cargo, as a result of which the car body has an increased length along the frame to obtain the necessary loading volume, which leads to an increase in the mass of the car (tare) and the length of the train;

- with an increase in the mass of the car, due to the restriction on the permissible load from the axis of the wheel pair on the rail track, the possibilities of increasing the carrying capacity of the car are limited;

- in existing constructions of gondola cars, the indicator “allowable load per linear meter of the track” is significantly underutilized;

- the body design of the gondola car according to the patent [8] allows to increase the loading volume of the car only partially.

Also known are the designs of covered hopper cars of model 19-752 for transporting grain, hopper cars of model 19-758 [5] for transporting cement, hopper cars of models 19-9835, 19-9835-01, 19-9870 [6], intended for transportation of granular, coarse-grained and crystalline non-caking mineral fertilizers, hopper gondola cars of models 20-471 and hopper dispensers [9].

The listed car models include chassis (trolleys) typical for freight cars, braking equipment, an automatic coupler and a body formed by flat vertical side walls, inclined end walls and a frame into which bunkers with unloading hatches with covered lids are welded. Unloading of such cars is carried out gravitationally: with the open covers of the unloading hatches, the cargo slides along the inclined planes of the end walls and the walls of the bunkers to the unloading hatches.

Known designs of hopper cars cannot be used for transportation of goods with unloading on tipper cars.

Also known is the design of the car according to the patent [7]. The main disadvantage of this design is that the design developments proposed in it are oriented to the body frame, which does not have a through beam across the entire length of the spinal beam. The use of such structures in freight cars is limited, since cars without through spinal beams cannot absorb and transmit large longitudinal loads and, therefore, impose restrictions on the possibility of increasing the mass of the train.

The purpose of the proposed utility model is to reduce the length of a gondola car along the frame and along the clutch axles of automatic couplings while maintaining or increasing the loading volume of the body without increasing the mass of the car by using bunkers welded into the body frame and lowered below its level in the body structure.

A gondola car with a deaf body is proposed, including chassis (trolleys) typical for freight cars, braking equipment, an automatic coupler and a welded body consisting of side and end walls in the form of frames covered by sheathing sheets, and a frame with a through spinal beam, end, pivot and intermediate transverse beams, characterized in that a hopper of a prismatic or cylindrical cross-sectional shape is welded into the frame on each side of the spinal beam, lowering into the carriage through a window, an image It is defined by intermediate crossbeams, a spinal beam and a lower side trim of the body.

The proposed design of a wagon with a deaf body allows:

- reduce the length of the gondola body along the frame and along the clutch axes of automatic couplings while maintaining the loading volume of the body;

- increase the loading volume of the gondola car body without increasing the body length along the frame and without increasing the mass of the gondola car;

- increase the actual carrying capacity of a gondola car;

- to form railway trains of the same mass from a smaller number of wagons;

- reduce the length of the train in comparison with the composition of the same mass formed from the wagons of existing structures;

- reduce the center of gravity of the body, increase the stability of the car from overturning in the curved sections of the track and the stability in the train from derailment.

To clarify the described object, the figures show the design of a gondola car with a deaf body. Figure 1 shows a view of the body of the gondola car in front (left symmetric part); figure 2 is a view of the body of the gondola car from above; figure 3 is a cross section of the end of the body with a view of the pivot beam. Figure 4 shows a cross section of the middle part of the body with a prismatic shape of the hopper. Figure 5 shows the same section with a cylindrical shape of the hopper. Figure 6 shows a longitudinal section of a frame with views of the end, pivot, first intermediate transverse beam and hopper (version 1). 7 shows a diagram of the separation of the hopper by a partition into compartments, with one hopper on each side of the spine beam in the area between the first intermediate beams (version 2). On Fig shows a longitudinal section of the frame with the number of bins more than one in the area between the first intermediate beams (version 3).

The proposed object is as follows. The gondola car with a deaf body (Figs. 1, 2) includes the chassis 1 typical for freight cars, the coupler 2, the brake 3, and the original welded body 4. The body includes two side walls 5, two end walls 6, and a frame with bins 7.

The frame includes a longitudinal spinal beam 8 (Fig.2, 6), transverse beams: end 9, pivot 10, first intermediate 11, lower side strapping 12 and longitudinal beams 13, supporting flooring 14 in the end parts of the body.

In the end parts of the frame in areas from the end beam 9 (Figs. 2, 6) to the first intermediate beam 11, the floor sheets with transverse edges rest on the upper belts of the transverse beams, and longitudinal - on the upper profile shelf of the spinal beam and reinforcement corner 15 (Fig. 3) .

In the middle part of the frame, in the area between the first intermediate beams 11 (Figs. 2, 6), on either side of the spinal beam, two hoppers 16 of a prismatic (Fig. 4) or cylindrical (Fig. 5) cross-sectional shape are welded into the frame.

The hoppers prismatic cross-sectional shape include two end walls 17 (figure 4), two side walls 18 and the bottom 19 of sheet metal. The walls and the bottom are connected by reinforcing obtuse-angled corners 20. The end walls of the hopper are supported by two inclined beams 21 (Fig. 6), and the side walls and the bottom by transverse belts 22 (Fig. 4), the ends of which are welded to the spine and the lower side trim .

The cylindrical cross-sectional hoppers likewise include two flat end walls 23 (FIG. 5), two side docking sheets 24 and 25, a cylindrical bottom 26 and reinforcing belts 27.

If it is necessary to increase the transverse bending stiffness of the lower side strapping, the bins can be divided into compartments 28

(Fig. 7) by partitions 29 or additional intermediate transverse beams 30 (Fig. 8) may be included in the frame and more than one number of bunkers can be placed on each side of the spinal beam.

Thus, the proposed body design of a gondola car with a deaf floor allows:

- reduce the length of the gondola body along the frame and along the clutch axes of automatic couplings while maintaining the loading volume of the body;

- increase the loading volume of the car without increasing the length of the body along the frame and without increasing the mass of the gondola;

- increase the actual capacity of the car;

- to form railway trains of the same mass from a smaller number of wagons;

- reduce the length of the train in comparison with the composition of the same mass formed from the wagons of existing structures;

- lower the level of the center of gravity of the body and increase the stability of the car from overturning in the curved sections of the track and the stability of the train from derailment.
