Digital rope arrangement device for oil winch sand reel

Abstract

The invention discloses a digital rope arrangement device for an oil winch sand reel. The digital rope arrangement device for the oil winch sand reel comprises a mechanical system and a control system; the mechanical system is composed of a left support, a right support, a transverse guide rail, a lead screw, longitudinal guide rails and a pulley; the transverse guide rail is arranged between thetop end of the left support and the top end of the right support, and the outer wall of the transverse guide rail is sleeved with a transverse guide rail sliding block; the lead screw is arranged between the bottom end of the left support and the bottom end of the right support, and a lead screw sliding block is screwed to the outer wall of the lead screw; and a speed reducing box is arranged at one end of the lead screw, and the output end of the speed reducing box is rotatably connected with the input end of the lead screw. The digital rope arrangement device for the oil winch sand reel hasthe functions of fault correcting, position setting, speed ratio adjusting, winding direction rotating and rope winding counting; the control system is installed on a brake crank of the sand reel, andtherefore the oilfield anti-explosion requirement is met; and the mechanical system is installed in the mode of being flush with a top plate of a winch rack, disassembling is not needed in the carrying and moving process, and the transformation requirement of an existing sand reel for an oilfield is met.

Description

technical field [0001] The invention relates to the field of vehicle-mounted drilling and repairing equipment in oil fields, in particular to a digitalized rope arranging device for a sand fishing drum of an oil winch. Background technique [0002] The drawworks sand fishing drum for vehicle-mounted drilling and repairing machines in oil fields is equipment for sand fishing, testing, oil testing, auxiliary lifting, handling drill stuck accidents, extracting core barrels and salvaging fallen objects. The positive and negative rotation of the drum and the release of the wire rope can achieve the purpose of lifting and lowering the suspended heavy objects to meet the requirements of the depth, weight and speed of the downhole. With the development of the oil drilling industry, the safety, utilization and operation of the equipment The efficiency is getting higher and higher, and the reliability of the equipment is required to be higher. The body of the sand fishing drum is a sm...
