Gearbox suspension type locking disc connection small module drilling winch

Abstract

The invention discloses a gearbox suspension type locking disc connection small module drilling winch, and relates to the field of oil field drilling and repairing machine operation equipment. A winchis driven by an alternating-current variable frequency motor, a gearbox transmits power, a main brake is a hydraulic disc brake, an auxiliary brake is a main motor energy consumption brake, a brake disc is installed on the left side of a single roller shaft, and the right side is connected with the gearbox through an idle sleeve suspension type locking disc locking structure. The winch is composed of the roller shaft, a machine frame, a disc brake, a shock absorber, a locking disc, the gearbox, a drill feeding device, a coupler, an angle box, a motor, a lubricating system, an alternating-current variable-frequency control system and the like, the alternating-current variable-frequency motor drives the angle box, a winch shaft is driven by the gearbox, and a roller is driven to achieve ascending and descending of a traveling block. An all-digital vector control voltage source type alternating-current variable-frequency speed regulation device is adopted, a V / f characteristic curve frequency control mode and a magnetic field orientation vector control mode are achieved, and the drill feeding device is connected with a gearbox clutch and is an independent driving system.

Description

technical field [0001] The invention relates to the technical field of oil field drilling and repairing equipment, in particular to a small module drilling drawworks with a gear box suspension type locking disc connected. Background technique [0002] The drawworks equipped with oilfield drilling and repairing machines are responsible for tripping, running casing, making up and breaking out, controlling the drilling pressure during the drilling process of the drill bit, dealing with stuck drills, workover, extracting core barrels and salvaging objects, and automatically feeding Drilling and other operation equipment, with the localization of oil drilling and production equipment in China, many types of winches have been developed. According to the driving mode, the winches include mechanical drive, DC drive, and AC drive. According to the number of winch shafts, there are single-axis winches and multi-axis winches. , according to the gear position, there are single-gear winc...

Problems solved by technology

[0003] In the prior art, the wheeled drilling rig uses a vehicle-mounted engine as power, drives a transfer case through a hydraulic torque converter and a transmission shaft, and the transfer case drives an angular gearbox, and the angular gearbox drives the winch sprocket through a chain transmission, and the pneumatic tire clutch Clutch roller shaft, winch is belt or disc brake, pneumatic push disc auxiliary brake, winch is single shaft or equipped with sand fishing drum shaft, the overall technology is more traditional, simple in function, complex in transmission route, takes up a lot of space on the frame, and has troubles There are many points, and maintenance is inconvenient. With the development of petroleum equipment technology, AC frequency conversion drive is the mainstream of petroleum equipment development. AC frequency conversion control technology has been developed maturely, with excellent speed regulation, strong overload capacity and anti-interference ability, and easy operation. , save time and labor, simple installation, easy maintenance and maintenance, the system is convenient for the integration of machine, electricity, liquid, gas, instrument, digital and communication, meets the requirements of safe operation, the structure and configuration are simpler, and generally reach the international advanced level, traditional technology Configuration cannot meet the development of intelligent technology
