Problems solved by technology

This kind of power source must convert fuel into power through the engine, and then the output shaft drives the gearbox to drive the winch drum, and its efficiency is relatively low
After the oil pipe or oil rod is raised or lowered, in order to ensure the next work and the work of the hydraulic tongs, the engine cannot stop running, and the stop of the winch drum must be separated from the engine power, so that a clutch must be used between the engine and the winch drum to work When the clutch is frequently disengaged, the operation is cumbersome and the structure is complicated
Due to the structure of the workover rig using the engine as the power source, the brake can only brake the winch drum, resulting in large braking torque, fast wear and high maintenance costs.
Based on the above reasons, the fuel-powered engine-driven workover rig has the disadvantages of complex structure, bulky size, high cost, high operating cost and high maintenance cost.

Abstract

The stepless speed regulating well repairing apparatus consists of operating room, console, hydraulic mechanism, pedestal, hydraulic tongs, crown block, frame, roller, speed variator, motor, brake, control cabinet, traveling pulley and rotary hook connected together. The present invention has the advantages of simple operation and low power consumption.

Description

1. Technical field [0001] The invention belongs to general workover equipment for oilfields, in particular to a stepless speed regulation workover device. 2. Background technology [0002] At present, during workover in oilfields, diesel, gasoline, and gas engines are usually used as the power source of workover machines to achieve the purpose of lifting or lowering oil well strings and downhole tools. This power source must convert fuel into power through the engine, and then the output shaft drives the gearbox to drive the winch drum, and its efficiency is relatively low. After the oil pipe or oil rod is raised or lowered, in order to ensure the next work and the work of the hydraulic tongs, the engine cannot stop running, and the stop of the winch drum must be separated from the engine power, so that a clutch must be used between the engine and the winch drum to work When the clutch is frequently disengaged, the operation is cumbersome and the structure is complicated. ...
