Problems solved by technology

[0003] However, in the prior art, when the brake test is performed on the elevator, it is necessary to provide power for the brake electromagnet, and the control switch needs to be connected in series in the power supply circuit of the brake electromagnet, which requires changing the electrical structure of the elevator and reconnecting line
The operation is more complicated and the test efficiency is lower
At the same time, there may be misoperation of the positive and negative poles of the brake electromagnet being reversed during manual wiring, which will burn the brake electromagnet and cause more serious accidents, resulting in certain risks during the test
[0004] There are at least the following problems in the prior art: the existing brake test method is relatively complicated to operate, the test efficiency is low, and there are certain risks in the test process

Abstract

The invention provides an elevator single-arm brake-sticking testing device and method. The elevator single-arm brake-sticking testing device comprises a testing box, an interface module and a switchmodule. The testing box is used for mounting of electrical parts required by brake-sticking testing; the interface module is arranged on the outer surface of the side wall of the testing box and comprises a plug-pull-type interface matched with plugins of an elevator control cabinet, and the plug-pull-type interface is electrically connected with the corresponding electrical parts; the switch module comprises a shift switch and an emergency stop switch; the shift switch is arranged on the outer surface of the side wall of the testing box and used for energizing or de-energizing of a brake-sticking electromagnet, and a button of the emergency stop switch is arranged on the outer surface of the side wall of the testing box. By utilizing the elevator single-arm brake-sticking testing device and method, testing operation can be simplified, the testing efficiency is improved, and the testing risk is reduced.

Description

technical field [0001] The present application relates to the technical field of elevators, in particular to an elevator single-arm brake testing device and method. Background technique [0002] In the case of a sudden power failure of the elevator, the elevator brake can brake the moving elevator car to stop, so as to ensure the safety of the passengers. However, when the elevator locks, there may be accidents such as elevator slipping, rushing to the top, and squatting at the bottom. Therefore, it is necessary to perform a brake test on the elevator to determine whether the brake behavior of the elevator is abnormal. [0003] However, in the prior art, when the brake test is performed on the elevator, it is necessary to provide power for the brake electromagnet, and the control switch needs to be connected in series in the power supply circuit of the brake electromagnet, which requires changing the electrical structure of the elevator and reconnecting line. The operat...
