Abstract

The invention relates to a test device of an elevator car ascending overspeed protection device, which mainly solves the problem that the unified test device suitable for all the car ascending overspeed protection devices does not exist at present. The test device comprises an elevator control cabinet and an ascending overspeed protection device. The ascending overspeed protection device comprises a speed limiter and a band-type brake and further comprises a rope clamper, a car safety tong and a counterpoise safety tong, wherein the band-type brake is connected with the control cabinet, the rope clamper or the car safety tong or the counterpoise safety tong is connected to the speed limiter, a switch is arranged on the band-type brake, the speed limiter and the rope clamper or the car safety tong or the counterpoise safety tong respectively, the test device is connected between the control cabinet and the ascending overspeed protection device, the band-type brake is connected to the test device, and the switches on the band-type brake, the speed limiter and the rope clamper or the car safety tong or the counterpoise safety tong are connected to the test device respectively. The test device is suitable for testing the drag-driven elevator car ascending overspeed protection devices of all the manufacturers, and is safe and reliable in test operation and simple in test procedures.

Description

Technical field [0001] The present invention involves the field of elevator technology, especially a test device that is suitable for all cars that drive the elevator. Background technique [0002] In some accidents, the leading elevator cars may occur at speeding up.Under such accidents, in order to ensure the safety of the elevator, the traction drive the upward speed protection device of the car is installed inside the elevator.The clipper on the suspension rope or compensation rope), or the speed limiter plus the two -way safety pliers acting on the car, or the speed limiter plus the function of the heavy piping of the heavy topComposition on the lock on the traction wheel. [0003] According to the "Elevator Manufacturing and Installation Safety Specifications", the upward speed protection device needs to be tested. HoweverVarious tools and different test methods verify the upward speed protection device of the car, so that there are some shortcomings: [0004] 1. The test p...
