Description

The invention relates to railway transport, in particular to wagons and containers for transporting bulk cargo with side unloading.

Known freight cars for transporting bulk goods (SU 854788 and SU 1094782) with containers located on both sides of the longitudinal axis of the car, pivotally connected to each other in the upper part and fixed by hinges to the racks with the possibility of turning the drive with or without a vertical plane to open hatches.

The disadvantage of these designs is the increased metal consumption due to the inner walls of the tanks and the reduced useful volume of the bins. In addition, the effort aimed at turning the containers to open and returning them to their original position is reduced due to the fact that when opening the load pressure is distributed in the hopper to the connected front and rear walls and only partially helps to open, and when closing an empty hopper the presence of the rear wall shifts the common center of gravity of the hopper to the suspension point, reducing the shoulder closing moment.

Also known is a freight car for transportation of bulk cargo (SU 1773764), comprising a body mounted on a frame, formed by two containers located on both sides of the longitudinal axis, pivotally mounted to the uprights with the possibility of rotation in the vertical plane in opposite directions. The containers are made with opening bottoms mounted for movement along roller bearings fixed to the transverse beams of the frame. The junction zones of the tanks at the ends and in the lower part are blocked by a flexible element.

A disadvantage of the known design is that the flexible element has low reliability, is difficult to perform, the flexible element is subject to deformation during loading and creates additional resistance when opening. In addition, the known design is provided only for covered wagons.

The purpose of the invention is to simplify the design, the exclusion of unreliable flexible element and the expansion of functionality.

The problem is solved in that in a freight wagon or container for transporting bulk cargo containing a body mounted on a frame, formed by two semi-bunkers located symmetrically relative to the longitudinal axis, which are pivotally mounted in the upper part of the racks. Moreover, the half-bunkers have the ability to rotate in a vertical plane in opposite directions and are made with opening bottoms mounted to move on roller bearings, which are mounted on the transverse beams of the frame. In the lower part, the half-bins are pivotally connected by a hinge ridge, and at the ends in the joint zone of the half-bins, the end sheets of the half-bins overlap one another and are compacted relative to each other. There is also a seal between the end of the ridge and the end sheet of the half-bin.

Features and advantages of the invention will become more apparent from the description of preferred embodiments of the invention, given solely as an example, with reference to the accompanying drawings, where:

The wagon (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6) consists of a supporting frame 1 supported by two bogies 2. The frame consists of transverse beams 3 on which the rollers 4 are mounted End racks 5 are installed at the ends of the frame, on which longitudinal half bunkers 7 with lower longitudinal beams 8 are suspended using axes 6. The half bunkers are interconnected by an articulated ridge 9, which is hinged on the longitudinal beams 8 of half bins 7 along the entire length of the beams. The half-bins 7 in the upper part form a slotted loading hatch with a cover 10. In the lower part, the half-bins are interfaced with the hatch covers 11. The hatches 11 are hinged to the longitudinal beams 8, rigidly connected to the end walls of the half-bins, and are supported on rollers 4. The cross beams 3 are fixed to spinal beam 12 of the frame 1. The end sheets 13 and 14 of the half-bunkers go behind each other and are compacted together. The end sheet 13 contacts through the seal with the end face of the hinge ridge 9.

The open car (Fig. 7, Fig. 8 and Fig. 9) is made without a roof and a loading hatch 10.

In the container (Fig. 10, Fig. 11, Fig. 12 and Fig. 13) the half-bins 7 are located inside the frame of the container 15, and the rollers 4 are fixed on the frame of the container 15. Racks 5 are also rigidly fixed to the frame of the container.

In the carriage (Fig. 14, Fig. 15 and Fig. 16), the end sheets of the half-bins 13 'and 14' do not go one behind the other below the axles 6, but are connected through a seal to the sheet 16, which is rigidly fixed to the end posts 5, and it contacts through the seal with the end face of the hinge ridge 9.

The device operates as follows.

When unlocking the half-bunkers 7 of the loaded wagon under the action of the load pressure on the walls and the bottom, the half-bins rotate around the axis 6, while the bottom 11 rolls on the rollers 4, opening the container for unloading. In the upper part, the loading gap decreases. The hinge ridge 9 rotates and its angle of inclination approaches the angle of inclination of the lower manhole covers 11. The sealing elements of the ridge 9 are in contact with the sheet 13, providing a seal, and the seal between the end sheets 13 and 14 provides a seal at the ends of the car. In the open position, the semi-bins are held by locking.

In the empty state when unlocking the half bins 7 due to the fact that the center of gravity of the half bins in the empty state is shifted relative to the axis of the suspension 6, a moment is formed and the half bins rotate to their original transport position, in which the half bins are blocked for subsequent loading.

This design of the car allows you to unload and bring the car to the transport position without an additional drive, make better use of the volume, do not fill up the undercarriage when unloading, transport caking and difficult to unload goods due to the large angle of the bottom during unloading and a wide opening along the entire length of the car. Moreover, the design of the carriage is simple and does not have complex shapes. Only due to the full use of volume, in comparison with traditional designs for similar cargoes, with the same internal volume, the proposed car is 30-35% shorter and, accordingly, less metal-intensive. Such data were obtained during the design and manufacture of the car, corresponding to the copyright certificate SU 1094792, and in the proposed design, these and other indicators will be further improved.

For containers with standard dimensions, this design will allow more full use of load capacity.

There is a simple synchronization design for simultaneously opening both hatches and a locking device.

Specialists in this field will easily find that various configurations and modifications are applicable to the above example implementation of the invention without deviating from its essence formulated in the proposed claims and defined by them.
