SU30612A1 - Device for simultaneous catching of the upward and downward conveyor chains at the break - Google Patents

Description

The invention relates to devices that are used for simultaneous capture, with an upward and downward conveyor chain broken, and equipped for this purpose with a movable rod in the guide bar extending across the course of one branch of the chain when the other is broken.

In the proposed adaptation, the movements of the chain catching rod are connected by a ratchet wheel rotated by a conveyor chain, the teeth of which are pressed onto the end of the rod by a spring.

In FIG. Figures 1 and 2 depict a view of the device in two projections. X Fixture is mounted on beams 4 and 8 attached to box girders A of the conveyor. On the shaft 2, located in the bearings 3 attached to the beam 4, the gear wheel 7 is fixed, integral with the ratchet wheel 7. The wheel / with the teeth entering the guides of the conveyor belt receives rotation from the chain moving in the direction of the arrow, links In which the teeth are engaged

wheels 7. The rod 6 moving in the guides 5, clamping its end with the action of the spring 7 to the teeth of the ratchet wheel, does not prevent the rotation of the latter when the conveyor is working. When the chain is broken, its links shift the “position shown by the dotted line in FIG. 1, the next tooth of the wheel 7, which, nb exit from the guides B, prevents the chain branch from falling down. Simultaneously with the movement of the wheel / ratchet wheel 7, resting against the end of the rod 6, it moves the latter, as a result of which its opposite end enters the guides B of the second side of the conveyor and retards the fall in another branch of the chain. When the normal operation of the conveyor is restored, the rod 6 moves to its initial position under the action of the spring 7 attached to its other end.

The subject matter of the invention.

Claims (2)

1. A device for simultaneous catching of the ascending and descending chains of the conveyor at the break using a movable in guide rods extending across the course of one branch at the break of the other, characterized in that for the purpose of moving at the break of the chain of the rod 6 the end of the last spring 7 presses against the teeth of the ratchet wheel / driven in rotation from the conveyor chain. 2. In the device according to claim 1, use the spring 7 to return the rod b to its original position.
