Abstract

A device for transporting goods on vehicle platforms, comprising a lower frame with arms pivotally attached to it in a transverse vertical plane, on which arms the shoes are hinged for interaction with the side walls of the platform, movable in the longitudinal direction an intermediate element with a pad spring-loaded relative to it for interacting with a curved guide and a lever dilution mechanism, characterized in that, in order to increase reliability, a curvilinear the guide is movably mounted on the frame in the longitudinal direction, and the lever dilution mechanism is made in the form of a hinged parallelogram placed in a horizontal plane with the possibility of interaction of its two opposite hinges with stops that are made on the said curvilinear guide, and the other two with the plungers, which are movably mounted on the frame with the ability to interact with levers.

Description

The invention relates to railway transport, in particular, to devices for h, consolidating cargo in open wagons.

The purpose of the invention is to increase reliability.

FIG. 1 shows a device for the transport of goods, a plan view; in fig. 2 - the same, side view; in fig. 3 is a view along arrow A in FIG. one; in fig. 4 along arrow B in FIG. one; in fig. 5 is a view along arrow B in FIG. 3; FIG. 6 is a cross section of FIG. four.

The device for transportation of goods contains the lower frame 1 (Figs. 1 and 2). The supporting beams 2 have an axle 4 on the curved surface of the lower frame 1 using sleeves 3 and threaded through an aperture 5 of the intermediate element 6, on which the support beam 7.dl is mounted. cargo. A block 8 is inserted into the intermediate element 6. A spring 9 is placed between the intermediate element and the block 8, and in the block 8 there is a slot 10, through which the plug 11 fastening the movable block 8 on the intermediate element is inserted. The block 8 frictionally interacts with the curvilinear guide 12. At the ends of the curved guide 12 there are end stops 13, between which are hinges of the paralogram 14 (Fig. 2), hinged to the toes of 15. The TSP

rests on the lever 16 pivotally mounted on the beam 2 of the lower frame 1 by means of a bolt 17 installed in the beam 2 through an opening 18 with bushes 19. The bolt 17 is fixed by a nut 20 and linch pin 21 "On the lever 16 a shoe 22 is installed with a friction layer 23 (for example, rubber). The pushers 15 have vertical holes 24 for swapping the levers of the parallelogram 14 and horizontal holes 25 for swapping the levers 16. The lever 16 is connected to the turret 22 of the hinge with a bolt 26 (FIG. 5) fixed with a nut 27 and a pin 28. the levers of the parallelogram 14 are fastened to each other and to the pushers 15 (Fig. 6) by a bolt 29, a nut 30 and a cotter pin 31. The device is mounted on the floor 32 of the gondola car between the side walls 33. The movable guide 12 has a curved surface 34 for contact with block 8, and pa its curvature is less than the radius of curvature of the bearing surface 35 of the sleeves 3. Support beams 2 are interconnected by side curvilinear beams 36 connected to frame 1 by transverse beams 37. Support beam 7 for the cargo is equipped with slides 38 "Hinged parallelogram 14 is placed in the horizontal plane, its levers from the rear part are provided with a bevel 39 (figo 3), and the beam 2. is equipped with vertical ledges 40

The device works as follows

Depending on the width of the gondola, one of the outer holes 25 of the lever 16 is aligned with the holes 18 of the beam 2 and secured with bolts 17. Then the levers of the parallelogram 14 are connected to the pushers 15 so that, after installation in the gondola, the pusher 15 is in opposite direction with the levers 16 Then a crane (not shown) lifts the device for the carriage of goods onto frame 1, while the levers 16 rotate under their own weight at an angle 1 (fig. 3) up to the stop 39 into the vertical ledge 40 of the beam 2. Thus rgchag January 16 with the shoes 22 begin to rotate, as the shoes 22 abut the lower part of its

in the gondola floor 32 and under the action of the device for transportation of cargo, the angle If (fig. 3) decreases to zero and the shoes 22 occupy the position shown in fig. 1 and 3, tight to the walls due to the deformation of the friction layer 23 (rubber) and slightly fixed the device for the transport of goods. At the same time, the pushers 15 interact with the large part of the lever 16, which are connected with the mechanism of leverage, i.e. with articulated parallelogram 14.

When the load is mounted on the support beam 7, the cargo transportation device is tightly mounted on the floor 32 of the gondola and fixed relative to the gondola due to the friction between the beams 2 and the floor 32 of the gondola and due to the relatively slight friction between the shoes 22 and the side wall 33 of the gondola. When a load is subjected to a longitudinal inertial force, the load together with the intermediate element 6 begins to shift to the right or left depending on the direction: l of impact (Fig. 2). Since the axis 4 is provided with bushings 3, the force of the rolling force between the bushings 3 and the supporting surfaces 35 for the sleeves 3, less than the frictional friction force between the pad 8 and the movable curved guide 1.2. Due to the friction between the block 8 and the movable curvilinear guide 12, it shifts towards displacement of the load. At the same time, one of the ring stops 13 of the guide 12 presses on the levers of the parallelogram 14, which, trying to position in a straight line, press on the pushers 15, and the levers 16 press against the walls of the gondola car shoe-22, and the pressure on the side walls is greater, the greater the displacement of the intermediate element 6 from the middle position, since the radius of curvature of the surface 34 is smaller than the surface 35. Since the amount of displacement in increases with the force of impact, the pressure force of the shoe 22 on the side walls of the gondola increases, depending on the force of the impact. After removing the inertial load, the system returns to its initial state under the influence of gravitational
