Abstract

The invention discloses an air cylinder braking type sand reel brake device. The brake device comprises two brake belts which are arranged in parallel, multiple brake pads are arranged on the inner side of each brake belt, one end of each brake belt is a fixed end, the other end of each brake belt is a movable end, two movable ends are connected through a brake belt shaft, and the two ends of thebrake belt shaft are connected with two driving devices. The device has the beneficial effects that the air cylinder braking manner is adopted, the brake is flexible and rapid in braking, and labor intensity of a worker is greatly reduced. A brake handle is arranged, manual emergency brake braking is carried out, and the device is higher in safety. Manual cost on the site work can be reduced, welldrilling cost is saved, risks of leakage and environment pollution are reduced, the device is more energy-saving and environment-friendly, and the device is simple in mounting and manufacturing process and low in economic cost.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling and production equipment, and in particular relates to a brake device of a cylinder brake type sand dredging winch. Background technique [0002] In oil drilling operations, the sand fishing winch is an important part of the drilling rig. The sand fishing wire rope wound on the drum of the sand fishing winch is reversed through the sand fishing pulley on the crown block, and the realization includes downhole testing, oil testing and auxiliary lifting, etc. Sand fishing. The sand fishing winch is generally driven by an AC variable frequency motor, which drives the sand fishing drum after being decelerated by the cycloidal gearbox and the chain box. The main brake of the sand fishing winch is motor energy consumption braking, and the auxiliary brake is belt brake. The belt brake device generally transmits the braking torque through the linkage mechanism, mainly through the brake handle a...
