Problems solved by technology

Due to the angle of the pulleys on the tower crane and they are scattered all over the tower crane, it is necessary to climb up and down to work at high altitudes, which poses safety risks, and the procedures are cumbersome, increasing labor intensity

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 with figure 2 A method for replacing steel wire ropes of a hoisting mechanism of a tower crane includes the following steps:

[0020] 1) Lower the hook 7 to the tower crane platform or the ground, and release the lifting wire rope fixing 9 at the end of the boom;

[0021] 2) Start the hoisting mechanism 1 on the tower crane, release the old steel wire rope 8 on the reel 2, and at the same time, fix the end of the old steel wire rope 8 on the first rope winder 10 for rewinding, until the old steel wire rope 8 is nearly completely released;

[0022] 3) stop releasing the old steel wire rope 8, and remove the fixing of the old steel wire rope 8 on the reel 2, and connect this end with the rope head of the new steel wire rope 11 on the second rope winder 12;

[0023] 4) Continue to rewind the old steel wire rope 8, and u...

Abstract

The invention discloses a method for replacing a steel wire rope of a tower crane hoisting mechanism. A lifting hook is lowered to a tower crane platform or the ground, and the fixing of the hoistingsteel wire rope at the end part of a cargo boom is relieved; and the hoisting mechanism on a tower crane is started, an old steel wire rope around a winding drum is unwound, and meanwhile, the old steel wire rope is wound from the other end until the old steel wire rope is almost completely unwound. The hoisting steel wire rope does not need to pass through and wind around pulleys one by one, andthe pulleys are distributed at different places of the tower crane, so that the complicated operation with safety risks is omitted, the workload is reduced, the situation that a person climbs up and down is avoided, and the operation safety is improved.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a method for replacing a steel wire rope of a hoisting mechanism of a tower crane. Background technique [0002] At present, the hoisting mechanism of the tower crane uses a wire rope to drive the hook to do the lifting and lowering movement. After the wire rope is wound out from the drum of the hoisting mechanism, it needs to pass through the pulleys on the structure of the tower crane, the pulleys on the safety device, and the trolley. (Some tower cranes or unloaded trolleys), the pulleys on the hook, etc., are finally fixed at the root of the boom. However, the environment of the construction site is harsh, and if the steel wire rope is not properly maintained or accidentally scratched, it is very easy to break wires and strands. When the wire rope is damaged to affect the safe use of the tower crane, it needs to be replaced. The traditional method...
