Abstract

The invention relates to a braking performance detector of a brake of an elevator traction system, comprising a detecting box, an installing bracket and a data collecting processor, wherein a pressure sensor is arranged in the detecting box; the detecting box is fixedly installed on a pull rod of a detected brake by the installing bracket; the pressure sensor abuts against a top rod of the brake by a contact rod which extends out of the detecting box; and the pressure sensor is connected with the data collecting processor by a traction line. The braking performance detector avoids non-economycaused by permanently installing the sensor and the like in the brake in on-line detection, also ensures the use reliability of the brake of an elevator and has reasonable structure, high detection precision, convenient use, high reliability and wide practicability.

Description

technical field [0001] The invention relates to a braking performance detection device of an elevator traction system, and is especially suitable for detecting the braking force of an elevator block brake. Background technique [0002] With the development of the economy, elevators have become an indispensable means of transportation in daily life, so the safety and reliability of elevators has attracted much attention. The elevator braking system is an essential part to ensure the safe operation of the elevator. If the braking torque is insufficient, it will cause "sliding" ladders or even "flying" ladders and other elevators to fall, rush to the top or shear accidents. Most of the operation control and safety protection of the elevator finally depends on the action of the braking system to stop the elevator. Moreover, the braking force of the brake directly affects the ride comfort and leveling accuracy of the elevator. However, at present, the detection of the braking ...
