Description

one

FIELD OF THE INVENTION The invention relates to transport, in particular to loading and unloading devices.

Devices are known for unloading and loading wheeled vehicles onto vehicles comprising a fixed bridge pivotally connected to a movable one by means of a lifting mechanism by a bridge.

The purpose of the invention is to improve the mechanization of the processes of loading and unloading machines.

For this, the bridges are mounted on a shunting carriage, and the lifting mechanism of the movable bridge includes a rotatable L-shaped double-arm lever, the lower arm of which is connected to the movable bridge by means of a flexible organ. A counterweight is attached to this body. The upper shoulder is made with a longitudinal groove in which a pusher in the form of a rod is installed.

The pusher can have a spherical support. It is advisable to carry out the shunting carriage movable from the cable drive.

FIG. 1 shows an example of the device for loading and unloading wheeled vehicles onto a railroad car; in fig. 2 — node I in FIG. one.

The device comprises a fixed bridge 1, pivotally connected to a movable bridge 2 connected with a lifting mechanism. The bridges} and 2 are mounted on a shunting trolley 3 with automatic coupling attached to the front

2

4 wagon type. The cart travels along the rails of the cable drive 5.

The lifting mechanism of the movable bridge is located on the side wall of the trolley and includes a 5 rotary L-shaped double-arm lever b, the lower arm of which is connected to the movable bridge by means of a flexible member 7, for example a chain. A counterweight 8 is attached to the chain.

0 On the upper arm of the lever there is a longitudinal groove I in which the end of the pusher 10 is installed in the form of a rod having a spherical support 11 at the free end. The pusher is movable in the horizontal direction

5 and is located in the brackets 12. The double-arm lever is located on an axis 13 fixed to the side wall of the trolley. The device works as follows. When the train is loaded by a locomotive to load the machines, the latter is unhooked, and the operator turns on the drive of the trolley for coupling with the train, pulling it up and installing it at the loading ramp 14, Trolley with a raised movable bridge

5 approaches the head carriage, engages it and, reversing, pulls the train to the ramp. The protruding end of the pusher with a spherical support rests on the ramp, while the pusher moves in brackets.

0 and raises with the help of a two-armed lever and

flexible body counterweight. The movable bridge, freed from the action of the counterweight, is lowered from its own weight onto the floor of the head car. The trolley drive is turned off by a limit switch located at the ramp (not shown in the drawing). Car is loading under its own power. After loading, the maneuver trolley moves the train to the end of the maneuvering track, where the releaser automatically disengages the coupler.
