SU10200A1 - Electromagnetic device for braking the trolley out of the way - Google Patents

Description

The present invention relates: to: electromagnetic: devices for braking a trolley out of the way, in which the magnetic flux is closed through the rim of the wheel and can be applied in various areas, for example, on slopes in a mining yard, on capital and intermediate brooders, and to stop the car when the rope breaks. The said device consists of: an iron core coil, to which, when replenished, two iron rods with pole tips (cheeks) installed at a certain angle. At the time of braking, one of these cheeks, arranged movable, is pressed against the wheel rim and produces braking ;.

In FIG. 1 schematically depicts the proposed device; FIG. 2 - the same top view; FIG. 3 same / in perspective view; FIG. 4 - the proposed device installed on the way.

To perform braking in this way, the core 1 of the electromagnetic coil 4 with two grasping rails and the wheel rim rods 2 equipped with pole tips 3, one of which is arranged moving along the rail on the plane b rod.

At the moment the wheels pass between tips 3 - 3, when the wheel falls into the sphere of a magnetic field, the moving pole and end-member 3 is attracted to the rim of the wheel, and this is done by braking. When the current is switched off, tip 3 is pulled back by means of special springs 3 and the brake is released to receive other cars.

The braking forces of the wheel consist of: braking on its surface, braking on the wheel rim, and finally braking by rubbing the surfaces of the tips 3–3 as they pass.

By installing a step brake consisting of several magnets, smoother and more reliable braking can be achieved.

The action of the proposed brake is automatic, namely: when a trolley approaches, the latter by means of pressing on a rail contact or the like. Switches on current.

it is turned off by a special time delay relay. The braking or decelerating time can be adjusted, depending on the operating conditions.

Pre) patent pending.

1. Electromagnetic device for braking a trolley from a path in which magnetic flux is closed through a wheel rim, characterized by the fact that core 1 of electromagnetic coil 4 with two rails and wheel rim fitted with pole pieces is placed in the direction transverse to the path. 3, of which one is movable along the guides and is provided with springs 5, which serve to release the rim of the ring from frictional engagement with it when the current exciting the coil 4 is switched off.

2. With the device described in clause 1, pr (name of rail contact or the like, which serves for automatic connection of the brake solenoid coil 4 to the current circuit.
