ELECTROMECHANICAL BRAKING SYSTEM OF HOISTING PLANT Russian patent published in 2017 - IPC B66D5/02 F16D65/56 

FIELD: electricity.

SUBSTANCE: electromechanical braking system of hoisting plant comprises an engine control system, a switched reluctance motor (1), a brake drum (7), two spring-loaded brake pads (4) on the connecting rod (8), sensors (9, 10), a comparison unit (13), current sensors (18), a pulse width converter (16), a valve switch (15), a correction device (17). Rotation of console and its interaction area with the drum (7) by an angle of 18 degrees, a deceleration sensor (10), a force sensor (9), a screw pair (2), comparators (11, 12) are additionally introduced to the system. A braking effort control unit (14) is connected to the first input of the valve switch (15), which output is connected with the switched reluctance motor (1), the first output of the switched reluctance motor (1) by means of the screw pair (2) is connected with lever of the brake module, the output of the brake drum (7) is connected with the deceleration sensor (10), the force sensor (9), generated deceleration and force signals are transmitted to the inputs of the comparators (11, 12), their outputs are connected to the input of the comparison unit (13), DC voltage from the valve switch (15) powers the switched reluctance motor (1), the second output of the switched reluctance motor (1) is connected to the inputs of the current sensors (18), which outputs are connected to the inputs of the valve switch (15) by sequentially connected correction device (17) and pulse width converter (16).

EFFECT: reduced energy consumption, increased positional accuracy, increased efficiency of operation.
