Winding device capable of improving service life of steel wire rope

Abstract

The invention discloses a winding device capable of improving the service life of a steel wire rope. The winding device comprises a roller (1), the steel wire rope (2) and a pulley (4), wherein the roller (1) is provided with an inner layer rope carrying surface (3) and an outer layer rope carrying surface (5); the radius of the outer layer rope carrying surface (5) is more than that of the inner layer rope carrying surface (3); the steel wire rope (2) is wound on the inner layer rope carrying surface (3) for n layers and can smoothly transit and enter the outer layer rope carrying surface (5); the rope head of the steel wire rope (2) is fixed on the end part of the inner layer rope carrying surface (3); and when the steel wire rope (2) is wound on the roller (1), the rope section at an orifice of the steel wire rope (2) is positioned on the outer layer rope carrying surface (5). The winding device can improve the service life of the steel wire rope and has convenient manufacturing and reliable performance. The winding device can be applicable to the winding work of a rotary drilling machine and can be used in other winding devices.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hoisting device capable of improving the service life of steel wire ropes. Background technique [0002] At present, the hoisting device used on the rotary drilling rig is an ordinary hoisting device, and there is no special hoisting device for the rotary drilling working condition, and the hoisting device of the rotary drilling rig has two characteristics when it works: [0003] 1. When drilling, the winch lowers the drill pipe through the wire rope to drill holes, and then lifts the drill pipe to the outside of the hole to pour soil (slag discharge). Since there is a process of pouring soil every time drilling, when the drill bucket is lifted out The section of steel wire rope wrapped around the upper drum when the mouth is pouring soil (this section is the most frequently used and the most complicated rope section is defined here as: the opening rope section) is the most frequently used ...

AI Technical Summary

Problems solved by technology

[0005] However, ordinary hoisting devices do not optimize the drum design and installation design for these two characteristics, and usually the orifice rope section on the ordinary hoisting device is wound above the second layer (or even the third layer, etc.), so the hole The bite and wear between the ropes of the mouth rope section are relatively severe, so the service life of the steel wire rope is short
