Application method of friction liner capable of detecting steel wire rope tension and alarming

Abstract

According to the use method of the friction liner capable of detecting the tension of the steel wire rope and giving the alarm, friction liners are evenly distributed on a transverse shaft of a roller, the steel wire rope is wound in grooves of the friction liners, at least one sensor is arranged on the lower surfaces of the friction liners, a controller is arranged on one side of the roller, anda wire is arranged between the sensor and the controller; a wire is arranged between the controller and the alarm bell; according to the invention, the elevator can measure and report the current tension and the tension balance state of a plurality of steel wire ropes in real time in a static state and an operation state, can guide the tension adjustment time and numerical values needing to be adjusted, reduces the adjustment auxiliary time, improves the productivity and economic benefits, greatly reduces the unbalanced wear of friction liners, and improves the production efficiency. The maintenance frequency of the rope groove is reduced, the service life of the friction liner is prolonged, the service life of the steel wire rope is prolonged, the hoisting capacity and safety performanceof the hoister are improved, and major production safety accidents are reduced.

Description

technical field [0001] The invention relates to the field of hoist equipment, in particular to a method for using a friction lining capable of detecting the tension of a steel wire rope and providing an alarm. Background technique [0002] The deviation of the groove diameter of the friction liner of the multi-rope friction hoist, the difference in the mechanical properties of the friction liner, the length deviation of the suspension wire rope, and the deviation of the mechanical properties of different wire ropes are the main factors that destroy the tension balance of the wire rope. Unbalanced tension of the wire rope will lead to The wear of the liner is intensified, and the steel wire rope under high tension will soon be broken and broken, which will reduce the service life of the steel wire rope, and even cause major accidents such as tilting of the lifting container and jamming of the tank. [0003] In view of the above reasons, a method for using a friction liner tha...
