Abstract

The invention provides a device and a method for testing the service life of an elevator speed governor, wherein the device comprises a roller, a movable platform, a power system, a programmable logic controller and a detecting device; the programmable logic controller is connected with the power system and the detecting device; the roller is used for driving a tested elevator speed governor to rotate by a driving rope during rotation; the movable platform is used for moving the roller horizontally; the power system is used for providing power for the roller to rotate and the power for the movable platform to move horizontally; the programmable logic controller is used for controlling the operating condition of the power system and the detecting device; the detecting device is used for detecting the frequency of the running period of the tested elevator speed governor. The device for testing the service life of the elevator speed governor can be used for efficiently acquiring test data by the detecting device when having an elevator speed governor service life test.

Description

technical field [0001] The invention relates to the technical field of elevator safety testing, in particular to an elevator overspeed governor life testing device and an elevator overspeed governor life testing method. Background technique [0002] The speed limiter is an indispensable safety device in the elevator system. Its working principle is to send a signal in time to cut off the power supply circuit and make the traction machine produce a braking effect when the elevator is running at overspeed, running out of control or the suspension device is broken. If the elevator still cannot be braked, the safety gear installed at the bottom of the car will quickly stop the elevator car on the guide rail and keep it in a static state, thereby avoiding casualties and equipment damage accidents. It is very important whether the elevator speed limiter can send out signals in a stable and timely manner, so the elevator speed limiter must carry out corresponding life tests at the ...
