Double-groove parent-and-subsidiary type steel cable winding drum and steel cable winding method

Abstract

The invention discloses a double-groove parent-and-subsidiary type steel cable winding drum and a steel cable winding method. The double-groove parent-and-subsidiary type steel cable winding drum comprises a machine frame seat (2), a winding drum supporting seat (3), a winding drum rotating shaft (4), a winding drum disk (6), a winding drum main groove (7), a socket plate sliding opening (8), a winding drum auxiliary groove (9) and a winding drum isolation plate (10), wherein the winding drum main groove and the winding drum auxiliary groove are connected with the winding drum isolation plate;the winding drum main groove and the winding drum auxiliary groove are connected through the winding drum rotating shaft; the winding drum disk is connected with the winding drum main body; the winding drum disk is arranged on the machine frame seat through the winding drum supporting seat; the socket plate sliding opening is formed in the winding drum isolation plate; one end of a steel cable (1) is twined onto the winding drum auxiliary groove, and the other end of the steel cable (1) penetrates through the winding drum isolation plate through the socket plate sliding opening and is twinedonto the winding drum main groove, so that a first cable head (101) is located on the winding drum auxiliary groove, and is exposed, and a second cable head (102) is located on the winding drum main groove, and is exposed. Through the adoption of the double-groove parent-and-subsidiary type steel cable winding drum disclosed by the invention, the technique difficult problems existing in large-scale hoisting machinery replacement overhauling industry can be solved, the overhauling time is shortened, potential safety hazards are eliminated, and operation efficiency is improved.

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
