Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with specific embodiments.

[0047] The steel wire rope double twister in the reliability test method of the steel wire rope double twister of the present invention includes a wire take-up assembly, an outer overtwisting assembly, a wire collection assembly, a single wire pay-off assembly, a core wire pay-off assembly and an electric control cabinet . The test and verification items of the wire rope double-twisting machine mainly include no-load test and loading test. The loading test includes temperature rise test, vibration detection and noise measurement. The specific test steps are as follows:

[0048] 1) Detection tools and equipment preparation before the test

[0049] Instruments include infrared thermometers, noise detectors and vibration testers;

[0050] 2) Equipment inspection before the test

[0051] Check the equipment before the test to ensure that the assembly of each compon...

Abstract

The invention discloses a reliability test method for a steel wire rope double-twisting machine. An equipment no-load test prototype starts to run step by step from an initial working speed of 25 to 35 percent of the maximum rated speed, the speed of each step is increased to 8 to 12 percent of the initial working speed, and the lubrication condition of a bearing seat in a take-up assembly is observed; the equipment loading test is carried out step by step in sequence according to 25-35% of the initial working rotating speed of the maximum rated rotating speed, the increasing speed of each step is 8-12% of the initial working rotating speed, whether the twisted strand is qualified or not is detected, and if the twisted strand is qualified, temperature rise measurement, vibration detectionand noise measurement are carried out. The reliability test method for the steel wire rope double-twisting machine can achieve rapid verification after equipment assembly is completed, and does not need to go to a client side or an outfield for a test, and the method is short in period, low in cost and capable of finding problems in time and effectively checking the reliability of the equipment.

Description

technical field [0001] The invention belongs to the technical field of double-twisting machine test technology, and in particular relates to a method for testing the reliability of a steel wire rope double-twisting machine. Background technique [0002] Wire rope double twisting machine is a ply production equipment suitable for ropes or strands of elevator wire ropes, hanging basket wire ropes, and steel wire ropes for belts. The ability of equipment to perform specified functions without failure within a certain period of time and under certain conditions directly determines the reliability of the equipment. The wire rope double twisting machine is composed of mechanical parts and electric control system, with complex structure and mutual interaction. At present, most of the reliability assessment of equipment is carried out on the customer side or in the field. The test period is long, the test cost is high, and the problem is discovered late, which directly affects cust...
