Cable machine main rope river-passing balance safety device

Abstract

The invention provides a cable machine main rope river-passing balance safety device comprising a secondary tower side electric winch, a rear fixed pulley group and a front movable pulley group, wherein the secondary tower side electric winch passes through a pulley group which is formed by the rear fixed pulley group and the front movable pulley group by a drawing steel wire rope; the front movable pulley group is mounted on a temporary bearing cableway through a temporary bearing yard; the front movable pulley group is provided with a rope head connecting part; and the front movable pulley group is connected with a counter weight below the bearing cableway through a suspending frame. According to the cable machine main rope river-passing balance safety device disclosed by the invention, the suspending frame and the counter weight of the front movable pulley group are arranged, so that the gravity center of the front movable pulley group is reduced, and the front movable pulley group can be not unstable in a moving process due to the high gravity center when uneven speed control or weather influences of a last main rope river-passing phase exist or assemblies including system machines, electric parts, the temporary bearing yard and the like have faults; and therefore, the safety of operating personnel, a main rope and pulley assemblies is ensured.

Description

technical field [0001] The invention relates to the field of installation and construction of the main cable of a cable machine, in particular to a river crossing balance safety device for a main cable of a cable machine used in the final installation stage of a large cable machine main cable crossing a river. Background technique [0002] During the installation process of the cable machine, the installation of the main cable is the most critical step. The completion of the main cable crossing the river is an important stage and a key step in the installation process of the cable machine, because in this process, many difficulties need to be overcome, such as the main cable Cable transportation, installation of the main cable drum, galvanizing at the cable head, control of the main cable slipping, hoisting of the tension pulley block and tensioning of the main cable, etc., need to continuously optimize the main cable crossing the river during the installation process of the ...

AI Technical Summary

Problems solved by technology

Since the main cable is supported by the temporary bearing cableway and the temporary bearing, it is still in a state of no force, that is, no tension, and there is no other auxiliary balance means available when the front moving pulley block moves with the main cable to drive the temporary bearing, so During the moving process, the front moving pulley block is very likely to overturn due to the high center of gravity and instability, causing damage to personnel and equipment such as pulley assemblies
