Testing device for elevator rope sheave

Abstract

The invention discloses a testing device for an elevator rope sheave, and the device comprises a testing support, the upper part of the testing support is provided with a to-be-tested elevator rope sheave through an elevator rope sheave shaft, and the elevator rope sheave is provided with a plurality of rope grooves; the plurality of test ropes are used for carrying out static pressure test on the elevator rope wheel, and the test ropes bypass the rope grooves corresponding to the elevator rope wheel and are in contact with the rope grooves corresponding to the elevator rope wheel; the loading force monitoring device is connected with one end of each test rope; and the loading force applying device is connected with the other ends of all the test ropes. Static pressure tests of elevator rope sheaves of various specifications can be carried out, the elevator rope sheaves can be flexibly carried to various environments to be tested, and the defects that in the prior art, use is inconvenient, and the pressure load of a steel wire rope on the rope sheaves in a real scene cannot be simulated are overcome.

Description

technical field [0001] The invention relates to the field of elevator sheave testing, in particular to a testing device for elevator sheaves. Background technique [0002] Traction-type elevators are usually provided with multiple return sheaves or guide sheaves (collectively referred to as elevator sheaves in this article). Originally, these elevator sheaves are mostly made of metal. In order to save costs, save energy and reduce emissions, and use new materials to replace traditional materials, the materials of these elevator sheaves are increasingly replaced by nylon. [0003] In order to verify whether the performance of the nylon or non-nylon elevator sheave meets the requirements for use, a series of tests should be carried out, especially a thorough test of its mechanical properties. The typical test methods are static pressure test, and adding Compression resistance, impact, drawing, aging and other tests under various environmental factors such as high and low temp...
