Non-explosion-proof elevator brake shoe gap monitoring system

The utility model relates to a non-explosion-proof elevator brake shoe gap monitoring system which comprises a control cabinet, a roller, a brake disc, a brake block, an induction iron sheet, a brakeleg, a brake shoe gap sensor, a brake disc deflection sensor, an elevator motor, a high-speed shaft, magnetic steel, a speed measuring sensor, a speed reducer and a low-speed shaft. The brake discs are arranged at the two ends of the roller. The brake block is arranged on the brake disc; the induction iron sheet is arranged on the brake block; the brake leg is connected with the brake block; the brake shoe gap sensor is arranged on the brake leg; the brake disc deflection sensor is arranged on the brake leg; the magnetic steel is arranged on the high-speed shaft; the speed reducer is connectedwith the high-speed shaft; and the low-speed shaft is fixedly connected with the brake disc. The brake shoe gap monitoring device can be used for monitoring the brake shoe gap of the non-explosion-proof elevator, and is simpl
