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 method for testing the reliability of a steel wire rope double-twisting machine. The equipment is no-load test-the test prototype starts to operate step by step from the initial working speed of 25% to 35% of the maximum rated speed, and the speed of each stage is gradually increased to the initial working speed. 8-12% of the rotational speed, observe the lubrication condition of the bearing seat in the wire take-up assembly; equipment loading test - run step by step at the initial working speed of 25-35% of the maximum rated speed, and the speed of each stage increases gradually to the initial working speed 8 to 12% of the twisted strands, check whether the twisted strands are qualified, and if the twisted strands are qualified, perform temperature rise measurement, vibration detection, and noise measurement. The reliability test method of the steel wire rope double-twisting machine of the present invention can quickly verify after the equipment is assembled, without going to the client or field test, with short period, low cost, timely discovery of problems, and effective assessment of 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...
