Description

one

This invention relates to conveyor engineering.

Devices for braking carriages are known, for example, overhead pushing conveyors as they move along aclone sections of the track, including brake levers, braking carts, tilting inertial levers responsive to the speed of the carriage, and locking mechanisms.

The purpose of the invention is the implementation of braking depending on the speed of the trolley. For this, the brake levers and locking mechanisms of the proposed trolley are interconnected by inertial levers sitting on the same axis with the brake and interlocked with them by means of springs adjustable by the amount of braking force, and one arm of these levers reacts to the speed of the trolley and the other interacts with a locking mechanism, equipped with a protruding lever, interacting with the cart, disabling the locking mechanism through the lever system and returning the inertial lever to its original position.

FIG. 1 shows the described device; in fig. 2 is a section along A-A in FIG. one.

The device contains inertial levers 1 with rollers 2 and a return spring 5, interacting with a locking mechanism, sitting one axis 4 with brake levers 5 and interlocked with the last springs 6. The locking mechanism consists of a protruding lever 7 interacting with the carriage 8, and the retractable lever 9, interacting with the lever system, including valves 10 with loads 11 n locking dogs 12 with pressure rollers / 5.

The carriage 8, moving rapidly along the inclined part of the route, presses the rollers 2, turning the levers 1 at the same time. At the same time, the arms 5, pressing against the levers / by the spring, turn

6 with adjustable pressing force. If the speed of the cart exceeds the permissible, the levers 1, deflecting also with great speed, hit the surfaces B on the gates 10. At the same time, the loads 11 pass through the dead

point and throw the valves through the dogs 12, thereby locking the levers.

Continuing the movement, the cart presses the levers 5, overcoming the resistance of the springs 6. The resulting frictional force from the coherence of the surfaces B of the levers 5 and the lateral surfaces of the casing 8 inhibits the movement of the latter.

Continuing with reduced speed, the cart deflects levers 7. At the same time

levers 9 rotate by pushing the roller

13 dogs 12, deflecting the latter, releasing the closures 10. Under the action of the springs 3, the levers / and 5 return to their original position.

When the trolley is moving at a speed lower than the permissible swinging of the gates does not occur, and the trolley is slowed down only due to its contact with the rollers 2.

Subject invention

A device for braking carts, for example, a suspended pusher conveyor as they move along sloping sections of the route, including brake levers, braking the carriage, swinging inertial levers, which respond to

trolley speed, and locking mechanisms, characterized in that, in order to implement braking depending on the speed of the trolley, brake brakes and locking mechanisms are interconnected by inertial levers sitting on the same axis with the brakes and interlocking with them the magnitude of the brake force springs, with one

the shoulder of these levers reacts to the speed of movement of the trolley, and the other interacts with the locking mechanism, equipped with a protruding lever that interacts with the trolley, turns off the locking mechanism through the lever system and returns the inertial lever to its original position.
