A screw type oil pumping unit balance block adjustment device

Abstract

The invention discloses a balance block adjusting device of a lead screw type pumping unit. The screw type oil pumping unit balance block adjustment device includes four parts: a fixed unit, a moving unit, a clamping unit and a labor-saving wrench; the fixed unit includes a fixed seat, a bump, two first ribs and a positioning bolt; the fixed seat The upper end is used to pass through the lead screw, and the lower end is used to pass through the light rod; the moving unit includes the light rod, the lead screw, the driving gear, two driven gears, the driving gear shaft, the front protective cover and the rear protective cover, the main and driven The gear and gear shaft are located in the cavity formed by the rear and front protective covers; the wrench head of the labor-saving wrench is square, which matches the square hole on the drive gear shaft; the clamping unit includes a front splint, a rear splint and fastening bolts. The invention is applicable to balance weights of different sizes, and after installation, the position of the balance weight on the crank can be adjusted bidirectionally. The invention has a compact structure, is easy to assemble and disassemble, has precise position adjustment of the balance weight, good stability, and safe and labor-saving operation.

Description

Technical field: [0001] The invention relates to a screw-type oil pumping unit balance block adjustment device applied in the field of oil pumping unit adjustment and balance in the petroleum industry. Background technique: [0002] The load balance of the upstroke and downstroke of the pumping unit is crucial to the efficient operation of the pumping unit. If the pumping unit is operated in an unbalanced state for a long time, the working state of the crank pin will be continuously deteriorated, and it is easy to cause damage to the motor, crank connecting rod mechanism and reducer. The consequences of shortened life, broken sucker rods and wasted energy. At present, the commonly used method of adjusting the balance weight of pumping units is to move the crowbar, which requires multiple people to operate together. During the operation, the movement position of the balance weight cannot be accurately controlled. The movement is slow, the cycle is long, and the labor intensi...
