RU40731U1 - HOPPER WAGON FOR CARRIAGE OF BULK CARGOES - Google Patents

Abstract

The utility model relates to railway transport, namely, to the design of hopper cars designed for the transportation of bulk cargo. The purpose of the utility model is to reduce the effort of moving the slide gate when opening the hopper hatch to unload the hopper car. The essence of the utility model is that each hopper is equipped with a hinged panel that receives a significant part of the pressure from the bulk cargo in the body of the hopper car, which reduces the load on the slide gate, and thereby reduces the force of its movement when opening the hopper hatch for hopper car unloading. The technical result achieved by the utility model is to reduce the efforts of moving the slide gate when opening the hopper hatch for unloading the hopper car by redistributing the load pressure to the rotary panel and the slide gate itself.

Description

The utility model relates to railway transport, namely, to the design of hopper cars designed for the transportation of bulk cargo.

Known indoor hopper car with side discharge with a capacity of 2,600 cu. ft (prospectus PULLMAN INCORPORATED a division Pulman-Standard 200S. MICHIGAN AVE, CHICAGO, ILLINOIS 60604 U.S.A.), comprising a frame with a through spine beam mounted on two-axle bogies and an all-metal covered body rigidly fixed to the frame. Loading is done through loading hatches located on the roof of the car, and unloading through gravity slide devices located in the lower part of the bunkers.

The main disadvantages of the analogue include:

- the presence of a through spinal beam increases the dead weight (mass) of the wagon;

- inside the bunkers there are no supporting platforms for maintenance personnel when performing repair work inside the body;

- great efforts to move the slide gate when opening the hopper hatch for unloading the hopper car.

Known modular hopper car for transportation of bulk cargo (patent for invention No. 2220861 from 01.10.2004, Russian Federation), containing two trolleys mounted on reinforced cantilever parts of a frame equipped with pivot beams. The end walls of the body are supported by vertical power ladders parallel to the fence. At the corners of the intersection of the end wall of the body and the deck (roof) mounted handrails. The inclined sections of the compartments are equipped with triangular walls resting on pivot beams. On the deck loading hatches and mounting hatches are mounted, bolted with rubber seals. Partitions are installed between the compartments, equipped with windows for moving from the compartment to the bulk cargo compartment. The bunkers are equipped with unloading windows that are closed by a slide device. Along the sides of the body on top and at the level of the strapping

The frame belts are secured by a corner type beam. The bunkers are interconnected from the bottom side by transverse beams of the T-type, rigidly connected with the beams and partitions.

The cylindrical (drop-shaped) body shape allows the use of pneumatic discharge. The presence of large windows in the partitions ensures uniform distribution of materials in all compartments, both during loading and unloading of the car. On the pivot beam, a thrust bearing and side rails are fixed. To absorb shock loads, the pivot beam is supported by V-shaped struts and stiffeners connecting it to the hopper. The latter are interconnected by ribs resting on the transverse beams.

The main disadvantages of the analogue include:

- the implementation of the body in the form of a drop-shaped (elliptical) shape reduces the usable volume;

- inside the bunkers there are no supporting platforms for maintenance personnel when performing repair work inside the body;

- great efforts to move the slide gate when opening the hopper hatch for unloading the hopper car.

The prototype of the utility model is a hopper car for transportation of bulk cargo (utility model patent No. 34478 dated December 10, 2003 of the Russian Federation), containing a body equipped with loading hatches on the roof and discharge hatches with slide gates (discharge hatches) on the bottom of the bunkers attached below the power a frame equipped with reinforced cantilever parts with elements of the spinal beam to the level of pivot beams mounted on biaxial carts. The body consists of side walls, end walls, reinforced with ribs and uprights, which at the same time are the access ladder to the roof with loading hatches, power flooring, lightweight disconnecting walls and forming bunkers together with side walls and end walls. In the plane of the separation walls, T-beams of the frame are installed. Access inside the body to the power flooring is provided by a ladder. The cantilever parts of the frame between themselves and the side walls are connected by welding with angular profiles.

Power flooring consists of longitudinal sidewalls connecting pivot beams and a hopper, transverse ribs and rods rigidly mounted on the ribs along the hoppers.

The hopper wagon is loaded through the open loading hatches, and unloading through the gate unloading devices with the open loading hatches into the rail space.

The disadvantages of the prototype include the great efforts of moving the slide gate when opening the hopper hatch for unloading the hopper car.

The purpose of the utility model is to reduce the effort of moving the slide gate when opening the hopper hatch to unload the hopper car.

The essence of the utility model is that each hopper is equipped with a hinged panel that receives a significant part of the pressure from the bulk cargo in the body of the hopper car, which reduces the load on the slide gate, and thereby reduces the force of its movement when opening the hopper hatch for hopper car unloading.

The invention is illustrated by drawings, where:

figure 1 shows a General view of a hopper car for transportation of bulk cargo;

figure 2 is an end view of a hopper car for transportation of bulk cargo;

figure 3 - installation of the panel;

figure 4 - fastening flexible traction control panel according to the angle of rotation.

The hopper wagon 1 (Fig. 1) contains a frame 2, equipped with reinforced parts with elements of the spine beam and pivot beams 3 with backs 4, mounted on biaxial trolleys 5, a body 6, rigidly connected to the frame 2 and sliding gate devices 7 (unloading hatches ) The body 6 consists of side walls 8, end walls 9, reinforced by ribs 10 and uprights 11, which are simultaneously an access ladder to the roof 12 with loading hatches 13, power flooring 14, lightweight separation walls 15 and forming together with side walls 8 and end walls 9 hoppers 16. In the plane of the separation walls, T-beams 17 of the frame 2 are installed. Access to the inside of the body 6 on the power flooring 14 is provided by the ladder 18. The cantilever parts of the frame 2 are connected to each other and the side walls 8 by angular welding and profiles 19.

Between the gate unloading devices 7 and the power flooring 14 in the bins 16 pivotally mounted rotary panels 20.

Power flooring 14 (figure 3) consists of longitudinal sidewalls 21, transverse ribs 22 and rods 23, rigidly mounted on the ribs 22 along the hoppers 16.

The rotary panels 20 are pivotally mounted on the longitudinal sidewalls 21 by means of suspensions 24. The adjustment of the rotary panels 20 according to the angle of rotation a, greater than the angle of repose of the transported bulk cargo, is carried out by a flexible rod 25 through

loading hatch 13 by hinging the ring 26 (Fig. 4) of flexible rod 25 onto the hook 27 rigidly mounted on the stiffener of the roof 12. The hopper car is loaded through the open loading hatches 13, and unloading through the slide devices 7 with the open loading hatches 13 in the rail track.

Thus, the technical result achieved by the utility model is to reduce the efforts of moving the slide gate when opening the hopper hatch to unload the hopper car due to the redistribution of the load pressure on the rotary panel and the slide gate itself.
