Device and method for testing wearing life of steel wire rope

Abstract

The invention discloses a device and a method for testing the wearing life of a steel wire rope. The test device comprises a fixed pulley, a steel wire rope and a heavy object, and one end of the steel wire rope is suspendingly provided with the heavy object; the test device also comprises a motor, a winding disk and a test circuit, the winding disk is assembled on the motor, the other end of the steel wire rope passes through the fixed pulley and is fixed on the winding disk, and the test circuit is connected with the motor; the test circuit is used for controlling positive rotation and reverse rotation of the motor under a condition of a preset number of times for testing the wearing life of the steel wire rope, so as to driving the heavy object to rise and fall through the steel wire rope; when the preset number of times for testing the wearing life of the steel wire rope reaches, finishing of the test is reminded through the test circuit. The device and the method can allow testing personnel not to personally pull the steel wire rope to test and also not to always keep recording tensile times, and thereby reducing the fatigue intensity of the testing personnel; and the test device is simple, safe and reliable, and moreover, can improve the testing efficiency and safety.

Description

technical field [0001] The invention relates to life testing of steel wire ropes, in particular to a steel wire rope wear-resistant life testing device and method. Background technique [0002] Today, with the increasing development of science and technology, the reliability and safety of products are also used as the main indicators of product development and design. The quality of products is also inspected from these aspects, especially mobile lifting products are more secure in the process of customer use. Therefore, in the design process, the life test is generally carried out according to the actual use process of the customer, so as to improve the safety performance. [0003] If you need a mobile light tower with a height of 10 meters, it is composed of four 1000W lamps. Its operation process is as follows. First, raise the lifting rod, then raise the lifting rod, light up the lamps, and turn them off after use. Lower the elevating pole, and then fall down and place ...
