Automatic balancing device for tension of steel wire rope of large distance adjusting rope

Abstract

The invention relates to an automatic balancing device for tension of a steel wire rope of a large distance adjusting rope. The device is primarily composed of a plurality of basic mounting modules which are connected through sleeves and mounted in a force transfer rack. Each basic mounting module comprises two roller rope storage devices, two planet carriers arranged in the roller rope storage devices and four bevel gear transmission mechanisms mounted on two sides of the roller rope storage devices; the force transfer rack is primarily composed of a force transfer shaft, a side longitudinalbeam, a middle longitudinal beam, a cross beam, angle iron and a column. Each bevel gear transmission mechanism comprises an engaged bevel gear group, the crossed axis angle of which is 90 degrees. Bevel pinions are mounted on a branch bracket where the planet carriers are circumferentially and uniformly distributed, the tail end of the branch bracket is fixedly connected to the end covers of theroller rope storage devices, the inner sides of the planet carriers are mounted on a force transfer shaft through bearings, and the outer sides of the planet carriers are mounted in planet carrier grooves. According to the device provided by the invention, the length of the steel wire rope can be adjusted by rotating roller bodies to dynamically balance the tension. The device is high in structural reliability, stable in working performance and low in maintenance cost.

Description

technical field [0001] The invention relates to a steel wire rope tension automatic equalization device for large-distance rope adjustment, especially suitable for automatic tension balance of hoisting wire ropes in multi-rope hoisting of coal mine ultra-deep vertical shaft hoisting systems and super-high building high-speed elevators. Background technique [0002] With the increase of coal mining, the vertical shaft is developing in a deeper direction, and the tonnage of the lifting container is also continuously increasing; at the same time, with the increase of building height, the lifting distance of the elevator is increasing. Therefore, higher requirements are put forward for the lifting safety and the rope adjustment distance, and the tension balance of the hoisting wire rope becomes very important. [0003] At present, the steel wire rope tension equalization device mainly used in the market is designed based on the Pascal principle. The balance is achieved by connec...
