SU682425A1 - Ster conveyor for moving wheel sets of a car along a rail track - Google Patents

Description

one

The invention relates to devices for moving objects on a rail track and can be used, for example, by companies repairing railway rolling stock.

Piston-type pulsate conveyors are known, including a shaft that is movable in guides by means of a reciprocating drive, rotary pushers arranged on the rod for moving the load 1.

The closest solution of the known ones is a step conveyor comprising a rod, rotary pushers, pusher stops, a reciprocating drive, an additional rod and a controlled stop mounted on the route of the conveyor with the possibility of interaction with the additional rod.

The disadvantage of such conveyors is that they cannot be used as wheelset storage units. In the case of harvesting a part of the wheelsets, a path between the wheelsets equipped with a conveyor (for example, a crane) will form gaps that will not be filled when the conveyor is turned on.

The aim of the invention is to enable the accumulation of wheelsets.

This is achieved by the fact that the conveyor has a spring-loaded stop mounted on the rod in front of the pusher, and the additional rod is made of several sliders connected in pairs with the stops of the pushers and hinged links installed with their free ends in the spring-loaded stop with the possibility of reciprocating motion, while the adjacent pairs crawlers and links are set with the ability to interact with each other with their ends.

FIG. 1 shows a conveyor, side view; in fig. 2-5 are consecutive positions of the parts of the conveyor in the process of moving the wheelsets; in fig. 6-8 show the arrangement of the wheel pairs on the accumulation path and the sequence of their movement by the conveyor.

The conveyor is located along the axis of the track in the guides of the box-section shank 1, equipped with a reciprocating drive, for example, in the form of a reversible

winches, and hinged forwarders 2-4, interacting with the axles of movable wheel sets.

The pushers are made rotatable in both directions from the vertical position and fixed on the rod by axles, on which

springs 5 are worn, resting with their lower ends on strips 6, reinforced between the vertical walls of the rod.

On the slats 6 there are supports 7, on which an additional rod is laid, mounted for movement relative to the main rod 1 in the longitudinal direction. The additional rod is made of several paired sliders and hinged links rotatable in a vertical plane, with the adjacent pairs of sliders and hinge links being installed with the ability to interact with each other with their ends.

A hinge link 10 and an anvil 11 interacting with a spring-loaded anvil 12 are attached to a forward along the conveyor slider 8 installed in the guide sleeve 9. The free end of the link 10 is installed in the spring-loaded stop 13, the lower part of which is provided with a window for passage of the link. The upper part of the stop 13 is made in the form of a double-slope slide.

The additional rod also includes sliders 14 and 15, to which the hinge links 16 and 17 are attached. From the bottom, the slide 14 is provided with a stop 18, which interacts with a fixed stop 19, and a slide 15 - a stop 20, which interacts with a fixed stop 21. Rest stops 18 and 19 are displaced in transverse direction in the same direction from the longitudinal axis of the rod, and the stops 20 and 21 - in the opposite direction.

The free end of the link 16 is installed in a spring-loaded stop 22 (similar to the stop 13), and the end of the link 17 is installed in a spring-loaded stop 23. The slider 14 is provided with a stop 24 at the top that interacts with the pusher 2, and the slide 15 fits the stop 25 that interacts with the pusher 3.

All subsequent followers, sliders, articulated links and spring-loaded stops, the number of which corresponds to the number of wheel pairs placed on the conveyor, are similarly arranged.

Works pipeline as follows.

The wheel pairs to be moved are fed to the initial part of the conveyor, after which the drive of the reciprocating movement of the bar 1 turns on. When the bar moves forward in the direction of arrow A, the conveyor pushers, abutting the axles of the wheel pairs, move them by an amount equal to the bar movement. In this case, the stops on the sliders of the additional rod prevent rotation of the pushers by keeping them in a vertical position.

During the return stroke of the boom, the pushers, interacting with the axles of the wheel pairs, turn counterclockwise and pass under the axles without moving the wheel pairs. The path is gradually filled with wheelsets.

When the first wheel pair reaches the end of the conveyor, its movement is stopped, and the remaining wheelsets continue to move, filling the gaps between the wheelsets, if any.

In case there is a gap between the first wheel pair 26 and the second 27 (see Figs. 1 and 6), when the boom moves forward, the spring-loaded stop 13, interacting with its bevel with the axis of the wheel pair 26, lowers (see Fig. 2). This also lowers the end of the link 10, which is mounted horizontally. At the same time, the spring-loaded stop 23, interacting with the axis of the wheelset 27, lowers the end of the link 17. Link 16 does not lower because the spring-loaded stop 22, not meeting the axis of the wheelset in its path, remains in the upper position.

Upon further movement of the rod (see Fig. 3), the stop And engages the stop 12, whereby the slider 8 is mixed back against the rod 1. In this case, the end face of the link 10, abutted against the end face of the slide 14, moves it backward, the withdrawal of the stop 24 from under the pusher 2.

Since the end of the link 16 is raised, it passes over the front end of the slide 15, without moving it. Due to this, the rest of the sliders do not move, and the stop 25 and the stops that follow it remain under the pushers, preventing their rotation. During the subsequent movement of the rod 1 (see Fig. 4), the stop 11, the lowering of the spring-loaded stop 12, passes over it. The pusher 2, having met the axis of the wheel pair 26, turns clockwise and passes under the axis without moving the wheel pair. Other pushers, remaining upright, move the wheel sets by a distance equal to the rod travel. In this case, the pusher 4 moves the pair of wheels 27, filled the gap (see Fig. 5 and 7).

During the reverse stroke of the rod 1 (in the direction of the arrow B), the stop 11, the hook stop 12 moves the first slide to its original position. When the rod reaches the extreme right position, the stop 18, interacting with the stop 19, moves the slider 14 to the left, and the stop 20 - the slider 15. Similarly, all the other sliders of the additional rod move to their original position.

If there are gaps left on the track that are not filled with wheel pairs, they will be filled with the next boom movements. In the case when between the wheel pairs 28 and 29 (see Fig. 7) there are two positions not filled with wheel pairs, as the boom moves forward, the pushers 2-4 turn off and the other pushers remain in the working position. In re-

As a result, in two working strokes of the boom, the wheelsets move to the position shown in FIG. 8, fill in the gaps.

If the conveyor is not used on the dead-end accumulation path of the wheelsets, but on the through-track, the stop 12 is sunk, for example, by means of a power cylinder. As a result, the conveyor conveys the wheelsets beyond the limits of the rod 1.

When this conveyor is moving, the gaps formed as a result of the cleaning of a part of the wheel sets with a crane or due to their irregular arrival on the conveyor are automatically filled.
