Description

Technical Field

[0001] The present invention relates to the technical field of winches, and particularly to a geological survey steel strand servo winch. Background Art

[0002] Steel strands for geological exploration are important materials widely used in the field of geological exploration, usually composed of multiple high-strength steel wires stranded together. In geological drilling, the steel strand is used to connect the drill pipe and the hoisting system of the drilling rig, lower the drill pipe and the drill bit into the borehole, and bear the weight of the drill tool and various forces during drilling. A servo winch is a device for winding and unwinding and controlling the steel strand, and is used to control the lowering and hoisting of the drill pipe and the drill bit connected by the steel strand.

[0003] When the existing geological survey steel strand servo winch is in use, the steel strand is prone to accumulate on one side of the drum or be too dense locally, affecting the neatness of winding. At the same time, a large amount of sand and soil adheres to the surface of the steel strand, resulting in a significant reduction in the tightness of winding. Moreover, the wound steel strand is prone to rebound and become scattered, which is not conducive to unwinding for the next use. In addition, the traditional method of disassembling the drum requires the use of multiple tools and can only be completed through complex operating steps, increasing the labor input and operating difficulty.
