Winch rolling spiral rope arranging method

Abstract

The invention discloses a winch rolling spiral rope arranging method which includes: (a) first, a chain wheel (1) is driven by a chain to drive a bi-directional threaded rod (4) to rotate; (b) then, the bi-directional threaded rod (4) drives a sliding block nut (8) matched with the bi-directional threaded rod (4) through threads to move; (c) the sliding block nut (8) drives a rope arranging support (5) on the sliding block nut (8) to move to generate linear movement for arranging ropes; (d) after the sliding block nut (8) moves to a limit position, the direction of motion of the sliding block nut (8) is changed; and (e) the sliding block nut (8) moves toward the reverse direction to drive the rope arranging support (5) connected with the sliding block nut (8), so that a reciprocating rope arranging process is completed. Even arrangement of steel wire ropes can be achieved, and the winch rolling spiral rope arranging method has the advantages of uniform-acceleration reversing and uniform working, prevents the steel wire ropes from being messy in order arrangement and pressing each other, and avoids rope disorder and the phenomena of severe deformation, torsion, bending and knotting of the steel wire ropes.

Description

technical field

[0001] The invention relates to a winch rolling spiral rope laying method. Background technique

[0002] Although various types of winches have various structures, their essence generally consists of the following parts:

[0003] (1) Drum, drum shaft assembly, which is the core working part of the winch. The drum should have sufficient rope capacity to ensure that the rope is in good condition to prolong the life of the wire rope;

[0004] (2) The drawworks has a sensitive and reliable main brake mechanism and a good auxiliary brake, so that it can accurately adjust the drilling pressure, evenly feed the drilling tools, freely control the drilling speed and save the heaviest drill string during the drilling process. load brake;

[0005] (3) Cat head and cat head shaft assembly, used to meet the needs of making and breaking buckles with tongs and other auxiliary lifting. Some cathead shafts are also equipped with sand fishing drums for extracting core barr...
