Problems solved by technology

The hoisting sheave and hoisting rope used for workover of this structure of the well workover rig are far away from the center of the well, and the tubing is bent during the workover, and the traction force is not enough during the workover, so it is difficult to realize the workover. Well; only the high-speed end of the power transmission part is equipped with electric brakes, so when braking, each transmission part bears a huge impact, reducing the service life and performance of the equipment

Abstract

The invention refers to a kind of oil pumping and well repairing machine, it includes electric control cabinet, main frame, bracket platform, electric motor, electric brake, shaft coupling, speed reducer, oil pumping smooth pole, rope suspending device, pumping rod rope, weight box, weight rope hanging device, weight rope, protecting rope, protecting rope clamp, driving unit. One end of the protecting rope is connected to the weight rope hanging device, and the other end is fixed on the driving unit. The driving unit and braked wheel positioned on an end of the driving unit form the driving brake. Fixed pulleys are provided on the bracket platform. An end of workover rope is fixed on the driving unit, the opposite end of the rope is rounded the fixed pulleys and travelling pulleys, then is fixed on the bracket platform. The lower end of the travelling pulleys is attached to an elevator. A braking handles positioned on the bottom of main frame is used for controlling the braked wheel. It is reliable and convenient.
