Multi-rope tension balance adjusting device and adjusting method

Abstract

The invention discloses a multi-rope tension balance adjusting device and adjusting method, and belongs to the technical field of multi-rope lifting. The device comprises a plurality of tension balance units, wherein each tension balance unit comprises a hydraulic cylinder, a speed increasing module, a roller and a lifting steel wire rope; the hydraulic cylinder is used for transmitting torque, the speed increasing module is used for speed increasing transmission, one transmission end of the speed increasing module is in transmission connection with the hydraulic cylinder, the roller is in transmission connection with the other transmission end of the speed increasing module, and the lifting steel wire rope is wound on the roller; and the hydraulic cylinders of the tension balance units communicate with one another through communicating pipelines. According to the device, the mechanism that the communicating hydraulic cylinders can automatically balance the hydraulic pressure is utilized, the torque change in the hydraulic pressure balancing process is converted into the rotation of the rollers, then tension balance adjustment such as loosening or tensioning is carried out on the wound lifting steel wire ropes, large-range automatic adjustment can be realized in a limited equipment space, and the effectiveness and timeliness of tension balance adjustment can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of multi-rope lifting, and more specifically relates to a multi-rope tension balance adjustment device and an adjustment method. Background technique [0002] In the hoisting of high-speed elevators in ultra-deep shafts and super-high buildings, there are single-rope hoisting systems and multi-rope hoisting systems. The single-rope hoisting system is suitable for occasions with small loads, and the multi-rope hoisting system is suitable for heavy loads. . [0003] The current multi-rope lifting system has the phenomenon of unbalanced tension between multiple steel wire ropes, which is likely to cause damage such as broken ropes and shortened life of the steel wire ropes, seriously affecting the comfort and safety of riding. Therefore, the tension balance between multiple steel wire ropes It is very important for the experience, safety and efficiency of elevator passengers and mine hoisting. [0004] After ...

[0004] After retrieval, Chinese Patent Publication No.: CN 1178189 A; Publication Date: April 8, 1998; discloses a steel wire rope tension automatic balancing method and a suspension device, which adopts a buckle pull-out type formed by a middle plate, a side plate and an oil cylinder. The method is equipped with a suspension device to realize this method. The oil cylinder is set in the gap of the middle plate, the oil cylinder barrel is connected to the side plate by the pressure plate, and the middle plate pulls the oil cylinder plunger to compress the oil cylinder. The adjustment stroke is only 600~800mm. When the difference in rope length is too large, it is very difficult to manually adjust the rope. It is necessary to lock and fix the first rope at an appropriate position with a rope clamp or a special tool rope clamp, and then use an electric hoist or a hoist. The chain will be changed to hang the container on one side to lift the steel wire rope manually, and the torsion of the steel wire rope will cause the traditional tension balance device to twist the pull plate, increase the resistance, and make the adjustment invalid.
