Simulation test device for measuring brake reliability of traction machine

Abstract

The invention discloses a simulation test device for measuring the brake reliability of a traction machine. The simulation test device comprises a bottom plate and two guide wheel sets, wherein a first motor is fixedly mounted in the middle of the top end of the bottom plate; a left brake and a right brake are fixedly arranged on the left side and the right side of a first motor shell respectively; a traction wheel is fixedly arranged on an output shaft of the first motor; each guide wheel set is composed of two guide wheels; and the two guide wheels on one guide wheel set are fixedly mountedat the top end of the bottom plate. According to the simulation test device for measuring the brake reliability of the traction machine, a torque is generated through a gravity difference between a first gravity block and a second gravity block, so that on one hand, working conditions are closer to field use conditions, and on the other hand, power energy of adding the torque by electrification ina laboratory is saved; and the gravity difference between the first gravity block and the second gravity block is changed by adjusting the height of a second guide rail support, so that the working conditions can be closer to the field use conditions.

Description

technical field [0001] The invention relates to a test device, in particular to a simulation test device for measuring the reliability of a traction machine brake. Background technique [0002] The traction machine brake is an important safety component of the elevator, and it is required to conduct no less than 2 million times of action tests to test the performance of the traction machine brake. [0003] At present, the laboratory uses the power energy of energization plus torque. If the torque is measured by energization, the braking torque is relatively large, the current is required to be large, and the test time is long (more than half a year), which requires a lot of power consumption. Torque-generating power equipment also has high requirements, so no torque was added in previous reliability tests, which did not match the actual working conditions. Therefore, we improve this and propose a simulation test device for measuring the reliability of the traction machine b...

[0003] At present, the laboratory uses the power energy of energization and torque. If the torque is measured by energization, the braking torque is relatively large, the current is required to be large, and the test time is long (more than half a year), which requires a lot of power consumption. There are also high requirements for the electric equipment that generates torque, so the previous reliability test did not add torque, which does not match the actual working conditions
