Two-in-one limiter test platform and test method for determining speed and force

Abstract

The utility model relates to a two in one safety governor test-bed and the test method for velocity measurement and force measurement; wherein the pedestals of the measuring part are respectively connected with a tachometric device and a force measuring device. The tachometric device comprises a safety governor wheel carrier positioned on the table-board, two tensions and an adjusting wheel positioned under the table-board; two guide rails are connected between the underside of the table-board and the bottom surface of the bench; a driving motor is glidingly connected between the two guide rails, wherein the driving motor shaft is connected with the driving wheels and the driving wheels are connected with the safety governor wheels via an O-shaped driving strap; one end of the table-board is connected with a flexible continued arm and the ends of the flexible continued arm are connected with a detecting wheel carrier and a detecting wheel, while the detecting wheel is connected with an encoder and is contacted with the edge of the safety governor wheels. The force measuring device comprises a rope cable pulley equipped with a ratcheting locking wrench at the lateral face of the bench; a force sensor is in alignment with the tangential direction of the safety governor wheels; one end of the steel wire is connected with the rope cable pulley and the other and is vacant after bypassing the concave-groove of the safety governor wheel. The utility model has the advantages of simple operation and high detection efficiency, and is used for the test of the elevator security components.

Description

(1) Technical field [0001] The invention relates to a detection device and a detection method for elevator components, in particular to a detection device and a detection method for an elevator speed governor. (2) Background technology [0002] The elevator speed limiter is a device that limits the running speed of the elevator. It is combined with the safety gear as the most important safety protection device for the elevator, also known as overspeed protection and broken rope protection. If the speed limiter fails, the safety gear is useless, and the elevator loses the most reliable safety guarantee, and the car will rush to the top or pier the bottom, which will inevitably cause serious casualties. GB7588-2003 "Safety Code for Manufacture and Installation of Elevators" clearly stipulates the action speed value and pull force value of the speed limiter in detail. Therefore, the detection of the speed limiter action speed and pull force is a very important links. The exis...
