Double-groove female and female type wire rope drum and wire rope coiling method

Abstract

The invention discloses a double-groove mother-in-law steel wire rope reel and a wire rope coiling method. The reel includes a frame seat (2), a reel support seat (3), a reel rotating shaft (4), and a reel disc ( 6), reel main groove (7), groove plate slide (8), reel auxiliary groove (9) and reel isolation plate (10); reel main groove and reel auxiliary groove with reel isolation plate, The reel main groove and the reel auxiliary groove are connected by the reel rotation shaft, the reel disc is connected with the reel main body, the reel disc is set on the frame seat through the reel support seat, and the groove plate sliding opening is set on the reel isolation plate , one end of the steel wire rope (1) is wound on the auxiliary groove of the reel, and the other end passes through the separation plate of the reel through the sliding opening of the groove plate and is wound on the main groove of the reel, so that the first rope end (101) is located on the auxiliary groove of the reel and Exposed, the second rope end (102) is located on the drum main groove and exposed. The invention can solve the technical problems existing in the replacement and maintenance industry of steel wire ropes of large-scale hoisting machinery, shorten the maintenance time, eliminate potential safety hazards and improve operation efficiency.

Description

technical field [0001] The invention relates to a steel wire rope drum of a lifting appliance and a coiling method of the steel wire rope on the drum, in particular to a double-groove female-type steel wire rope drum and a steel wire rope coiling method. Background technique [0002] In major industrial and mining enterprises, ports and wharves, wire rope is an indispensable and common component of large-scale hoisting machinery, and it is also one of the three major safety devices. In the industry, the daily maintenance and service life of steel wire ropes also have strict technical specifications and standards: First, the cumulative number of broken wires in any pitch of the steel wire rope used online exceeds 10%, that is, the number of broken wires reaches 22 wires (total wire rope When the number of wires is 216 wires), it must be replaced or repaired according to the actual situation of its broken wires; second, the diameter of the wire rope is worn out by more than 7%...

AI Technical Summary

Problems solved by technology

This process is relatively strict on the surrounding environment, state requirements and time control; and these process steps can only be implemented at the production site according to the current situation, which will be affected by many factors such as mineral powder, rainwater, time and how to fix the wire rope. The impact of the safety factor and service life are reduced

[0006] Therefore, many maintenance safety hazards and defects such as long maintenance time, low work efficiency, and low safety factor caused by the drum steel wire rope coiling method of the prior art
