Drilling winch capable of achieving automatic rope arrangement

Abstract

The invention discloses a drilling drawworks for automatically arranging ropes, comprising: a drawworks frame, a motor, a gearbox, a drum system, a brake system and a rope arranging device. Wherein, the drum system includes a roller and a turntable, the roller is connected to the frame, and two turntables are respectively located on both sides of the roller; the brake system is located on the turntable of the roller system; the rope arrangement includes a bracket, The pulley and the speed limiter are provided with a track on the support, the pulley is buckled in the track and can slide freely on the track, and the speed limiter is located on the support. The beneficial effects of the invention are: when the drawworks starts drilling, the wire rope passes through the pulley to connect with the drill pipe, and the speed governor guides the pulley to move on the guide rail of the bracket, so that the wire rope falls on different positions on the roller. The invention can realize the automatic rope arrangement function of the winch machine, which is convenient to control, prevents the phenomenon of disordered ropes when starting and feeding the drill, and can arrange the steel wire ropes closely and orderly on the rollers without wasting the rope arrangement space, so that the roller system can reach a larger rope capacity.

Description

technical field [0001] The invention belongs to the field of oil drilling equipment, and in particular relates to a drilling drawworks for automatically arranging ropes. Background technique [0002] The drawworks is the lifting equipment in the drilling machinery. It mainly has the functions of lifting and lowering the drilling tools, running the casing and controlling the drilling pressure. It is the core component of the drilling rig. At present, drilling winches include single-shaft winches, double-shaft winches, three-shaft winches and multi-shaft winches, etc. However, the existing drilling winches generally do not have a rope arrangement system, and rope disorder often occurs when the drum lifts and lowers the wire rope during actual use. , leading to problems such as wire rope sorting disorder, mutual extrusion deformation, etc., seriously affecting the service life of the drilling winch. Contents of the invention [0003] In order to solve the problems in the pri...
