Steel wire rope protection device and rotary drilling rig

Abstract

The invention discloses a steel wire rope protection device and a rotary drilling rig. The steel wire rope protection device comprises a support mechanism and a rotary mechanism, wherein the rotary mechanism comprises a supporting portion and a rotary portion. The supporting portion is installed on the support mechanism. The rotary portion is rotatably installed on the supporting portion and provided with a rope through hole for a steel wire rope to penetrate through, and a brush is arranged on the inner wall of the rope through hole. When the steel wire rope protection device is used, the steel wire rope penetrates through the rope through hole of the rotary portion and is in contact with the brush in the rotary portion. The steel wire rope performs axial motion, the rotary portion performs peripheral rotation, the steel wire rope and the brush produce relative motions, the brush brushes off silt and other foreign matter on the surface of the steel wire rope to achieve the steel wire rope surface cleaning effect, a protection role is played on the steel wire rope, and the service life of the steel wire rope is prolonged.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a wire rope protection device and a rotary drilling rig. Background technique [0002] Steel wire rope is a flexible rope twisted with multiple or multiple thin steel wires, which plays the role of lifting, pulling, tensioning and bearing in material handling machinery. Steel wire rope has the advantages of high strength, light weight, stable operation, and is not easy to break suddenly. It is widely used in construction machinery such as rotary drilling rigs, cranes, and tower cranes. [0003] Steel wire ropes mostly play the role of lifting in construction machinery, such as the main winch wire rope of rotary drilling rig. As a lifting component, the steel wire rope needs to frequently go in and out of mud and sand during work, and also needs to shuttle between multiple fixed pulleys. In order to increase the service life of the steel wire rope, it is necessary to apply l...

AI Technical Summary

Problems solved by technology

Although applying lubricating oil can reduce the wear of the wire rope, the viscosity of the lubricating oil will increase the adhesion of the wire rope to small particles such as mud, sand, and gravel.

When the wire rope with the above-mentioned foreign matter is in contact with the pulley and the reel, the wire rope will be squeezed by the foreign matter, which will damage the surface of the wire rope and shorten the service life of the wire rope
