Abstract

The invention discloses a power verification device of an elevator without a machine room. The power verification device of the elevator without the machine room comprises a test circuit module. The test circuit module is connected between a band type brake power source of a band type brake control circuit of the elevator and a set of brake coils and used for enabling the set of brake coils to beswitched off after the preset time when the set of brake coils and the band type brake power source are switched on in order to artificially simulate the braking force insufficiency of the elevator. Thus, braking force verification of the elevator without the machine room can be conveniently carried out.

Description

technical field [0001] The invention relates to a braking force verification device for a machine room-less elevator. Background technique [0002] Article 8.3 of the Chinese regulations "Elevator Supervision Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" (TSGT7001-2009, Amendment No. 2) stipulates the inspection content and requirements for the accidental movement protection device of the car. Article (2) - If the elevator uses a brake with internal redundancy as a braking component, when the brake is lifted (or released) and fails, or the braking force is insufficient, the car door and landing door should be closed and the elevator’s brakes should be prevented. Normal start. [0003] For machine-room elevators that use internally redundant brakes as braking components, when verifying "insufficient braking force" on site, it can be verified directly in the machine room by operating the mechanical brake release device of the traction machine...
