Elevator landing door pendulum impact test rack

Abstract

The invention provides an elevator landing door pendulum impact test rack, which comprises a base, a main support and an upper support. The main support is internally provided with a first connection rod, a second connection rod and a third connection rod from the top down; the base is fixedly arranged at the lower end of the main support; the upper support is fixedly arranged at the upper end of the main support; the front end of the upper support is provided with a pull rod, and the back end thereof is provided with a pulley assembly; the pull rod is connected with a pendulum through a hanging member; a lock bracket device is fixedly arranged between the first connection rod and the second connection rod; the third connection rod is fixedly provided with a lifting device; the pulley assembly is provided with a steel wire rope; and one end of the steel wire rope is fixedly connected with the lifting device, and the other end thereof is connected with the upper end of the lock bracket device. Positioning operation is carried out through the lock bracket device, and power input is realized through the lifting device, thereby reducing labor intensity, improving test efficiency, realizing quantitative and qualitative test and eliminating unknown risk factors and uncertain factors influencing test detection.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a pendulum impact test frame for an elevator landing door. Background technique [0002] With the development of the elevator manufacturing industry, more and more attention has been paid to the safety performance of elevators, especially the safety performance of elevator landing door systems. For this reason, many elevator manufacturers and elevator component manufacturers have carried out the pendulum impact test of the landing door system required in the No. 1 amendment of GB 7588-2003 "Safety Code for Elevator Manufacturing and Installation". In order to prevent passengers from man-made impact or unpredictable impact when waiting for the elevator, causing the landing door to break away from the guide device, causing people to fall into the hoistway and causing safety accidents, it is necessary to carry out specific tests to make the landing door system comply w...

Problems solved by technology

[0003] The traditional test method completes the test by manually pulling the pendulum. During the test, there may be human factors affecting the kinetic energy of the pendulum impact, and there are also some risk factors that may exist during the test.

Because the current test method is relatively simple, difficult to operate, and labor-intensive, a new technical solution is urgently needed to solve the above technical problems
