Problems solved by technology

In the five fatigue testing machine models given in "GB / T 12347-1996", the tension of the traction rope on both sides of the bending pulley is the same, and the traction rope hardly slips on the bending pulley. This fatigue test has not considered The wear of the traction rope and the traction sheave, it is not appropriate to use the test results of this testing machine to judge the life of the elevator traction rope

Abstract

The invention discloses an elevator hoisting rope life span testing machine, which comprises a hoisting motor, a hoisting wheel connected with the hoisting motor, an unbalance load loading motor, a loading pulley connected with the unbalance load loading motor, a guide pulley arranged under the hoisting motor and the unbalance load loading motor, a hoisting rope tension pulley, a hoisting rope tension device suspended under the tension pulley, the hoisting rope around the hoisting wheel, the tension pulley, the loading pulley and the guide pulley, a limit mechanism arranged along a direction in which the hoisting rope moves relative to the hoisting wheel or the loading pulley, and a machine frame which is connected with the hoisting motor, the unbalance load loading motor and the shaft ofthe guide pulley. The machine can simulate the actual operation states of the hoisting rope and the hoisting wheel when the hoisting rope is engaged or disengaged with the elevator hoisting wheel anddetect the wear of the hoisting rope and the hoisting rope wheel.

Description

technical field [0001] The present invention relates to an elevator test equipment, in particular to a testing machine for simulating the actual running state of the traction rope and the traction sheave when the traction elevator traction rope engages in and out of the traction sheave, and carries out the life test of the traction rope . Background technique [0002] During the operation of the traction elevator, due to the different tension of the traction rope on both sides of the traction sheave, the traction rope will creep and slightly slip on the traction sheave. An important reason for the wear of the traction sheave. After the elevator runs for a period of time, the traction rope and the rope grooves on the traction sheave that are in contact with the traction rope will be worn to varying degrees. As the degree of wear increases, the diameter of the traction rope becomes smaller, and the traction capacity of the traction system itself changes, which will cause vib...
