Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] It is worth noting that the orientation words such as "up" and "down" involved in this article are all determined relative to the perspective of the drawings, and are only for the convenience of description, and cannot be understood as limitations on the technical solution.

[0028] Such as figure 1 As shown, a method for replacing the steel wire rope of a crane, the specific steps are as follows,

[0029] Release the lifting limit of reel 1, so that the rotation of reel 1 is not restricted by the lifting limit;

[0030] Cut the connection between the old wire rope 2 and the device above or below the reel 1, start the reel 1, and continuously release the old wire rope 2 until the last layer of the old wire rope 2 on the reel 1 is left, so that there are more turns left on the reel 1 Number of old wire rope 2, stop drum 1;

[0031] Cutting th...

Abstract

The invention relates to a crown block steel wire rope replacing method. According to the crown block steel wire rope replacing method, an old steel wire rope which is released from a winding drum andclose to the ground is cut off and connected with one end of a new steel wire rope, the fixed end of the other end of the old steel wire rope is loosened at the same time, a traction rope is connected at the fixed end of the old steel wire rope, then the winding drum is started, the old steel wire rope is released, the new steel wire rope is wound on the winding drum, when the joint of the new steel wire rope and the old steel wire rope reaches the fixed end of the winding drum, the connection of the new steel wire rope and the old steel wire rope is cut off, the winding drum is fixedly connected with the new steel wire rope through a winding drum pressing plate at the fixed end, and replacement of the new steel wire rope and the old steel wire rope is completed. According to the crown block steel wire rope replacing method, the labor intensity is lower, the working time is short, and the operation of replacing a new steel wire rope by rotating the winding drum for many times in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of overhead crane maintenance, more specifically, it relates to a method for replacing steel wire ropes of overhead cranes. Background technique [0002] Cranes in the metallurgical industry are heavy-duty special equipment. Among them, the crane lifting mechanism has high safety requirements for steel wire ropes, and the steel wire ropes must be replaced every once in a while. Generally, the crane lifting mechanism needs to be replaced every 6 to 8 months. Wire rope to ensure the quality of the wire rope and avoid accidents caused by the aging of the wire rope. The existing method of replacing the steel wire rope is to connect the rope head of the old steel wire rope with the rope head of the new steel wire rope, start the drum to make the old steel wire rope drive the new steel wire rope to rise to the drum position, and fix the rope head of the new steel wire rope on the side of the drum. At the steel st...
