The invention discloses a low-temperature vibration test device for a steel wire rope of a winding hoist, which includes a No. 1 reel and a No. 2 reel, a wire rope vibration mechanism, a linear sliding mechanism and a device arranged around the No. 1 reel for simulating the external environment temperature The low temperature and constant temperature device; the No. 1 reel and the No. 2 reel are arranged in parallel and are at different heights. One end of the steel wire rope to be tested is firmly connected with the first rope clamp at the No. 1 reel, and the other end is bypassed. The wire rope vibrating mechanism winds to the No. 2 reel and is firmly connected with the second rope clamp at the No. 2 reel; the wire rope vibrating mechanism is used to apply in-plane and outer lateral vibrations to the moving steel wire rope to be tested and Compound vibration. The low-temperature vibration test device for the steel wire rope of the winding hoist of the present invention can simulate the movement and wear of the wire rope of the winding hoist under different ambient temperatures and vibration forms based on the realization of the longitudinal vibration and composite vibration of the steel wire rope in the plane and outside at different ambient temperatures Behavior.
Description
Technical field [0001] The present invention relates to a steel rope winding cryogenic vibration test apparatus. Background technique [0002] Currently, a large mine hoist use more multi rope frictional multilayer wound type and way to transport goods and people uphole and downhole. Due to restrictions by the rope stress fluctuations, multi-rope friction hoist theoretical limit to enhance the depth of 1700 m, are no longer applicable deeper exploitation of coal resources, so South Africa, Canada and other countries began to use multi-layer winding hoist mining deeper mineral resources, to enhance the maximum depth of more than 3000 m, up to four layer winding layers. However, in our country, the provisions of Article 418, "Coal Mine Safety Regulations (2016 Edition)": "wound on reels of various layers of wire rope lifting device must meet the following requirements: Shaft in lifting or lifting personnel and staff no more than one layer of material, designed for the lifting of no...
