The invention discloses a steel wire rope tension automatic regulating device, which is arranged on at least one end of steel wire ropes, and comprises a rope end wedge sleeve and a hydraulic cylinder, wherein the rope end wedge sleeve is connected with the steel wire ropes; the hydraulic cylinder comprises a cylinder and at least two oil cylinders; the number of the oil cylinders is matched withthat of the steel wire ropes; a pull rod passes through the oil cylinders to connect each oil cylinder with a steel wire rope; a communication hole is formed between each two oil cylinders; and the plurality of oil cylinders are communicated. According to the elevator and the steel wire rope tension automatic regulating device thereof, which are disclosed by the invention, the automatic regulating and balancing of the tensions of the steel wire ropes can be realized without changing the conventional elevator steel wire ropes so as to slow down the wear of the steel wire ropes; in addition, when one oil cylinder is broken or leaks oil, other oil cylinders are not affected, and the steel wire ropes connected with other oil cylinders can continuously regulate the balance without affecting the riding comfort of the elevator and the service lives of the rope wheels and steel wire ropes are prolonged.
Description
technical field [0001] The invention relates to an automatic tension adjustment device, in particular to an elevator and an automatic tension adjustment device for steel wire ropes thereof. Background technique [0002] In the prior art, an elevator has multiple wire ropes, and each wire rope is independent of each other; due to the processing error of each sheave groove and the unevenness of the diameter of each wire rope, the tension of each wire rope changes when the elevator is running. , will cause aggravated wear of the sheave and wire rope, reducing the service life of the sheave and wire rope. Contents of the invention [0003] The object of the present invention is to provide an elevator and its steel wire rope tension automatic adjustment device, which can overcome the deficiencies of the prior art, ensure that the elevator can automatically adjust the tension between each steel wire rope during operation, and reduce the wear speed of the steel wire rope and the ...
