Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] A cylinder braking type dredging winch braking device, see figure 1 , including two brake bands 18, brake band shafts 11, two push rod spring brake cylinders 22, one end of each brake band 18 is a fixed end, and the other end is a movable end;

[0026] Each fixed end includes a fixed lug 17, a tie rod head 12, a short tie rod 8, and a balance plate 9 connected in turn. The tie rod head 12 and the short tie rod 8 are connected by a pin shaft 13, and the balance plates 9 of the two brake bands 18 are respectively passed by a pin shaft. Connect one end of the long pull rod 10, the long pull rod 10 includes the pull rod and the lug plugs at both ends, the pull rod and the lug plugs at both ends are connected by threads, and the long pull rod 10 is vertically vertical to the two brake bands 18 by rotating the pull rod, thereby adjusting Fo...

Abstract

The invention discloses a brake device for a cylinder-braked sand dredging winch, which comprises two brake bands arranged in parallel, a number of brake pads are installed on the inner side of each brake band, one end of each brake band is a fixed end, and the other end is a The movable end; the two movable ends are connected by a brake band shaft, and two driving devices are connected to the two ends of the brake band shaft. Beneficial effects of the present invention: adopting the cylinder braking type, the braking is flexible and fast, which greatly reduces the labor intensity of workers; equipped with a brake handle for manual emergency braking, the equipment is more secure; it can reduce on-site work The cost of manpower is reduced, thereby saving drilling cost; the risk of leakage and environmental pollution is reduced, and it is more energy-saving and environmentally friendly; the installation and manufacturing process of the invention is simple and the economic cost is low.

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...
