Auxiliary adjustment device for motor of oil pumping unit and operation method of auxiliary adjustment device

Abstract

The invention relates to the technical field of oil field exploitation, and discloses an auxiliary adjustment device for a motor of an oil pumping unit and an operation method of the auxiliary adjustment device. The auxiliary adjustment device comprises an oil pumping unit base, a bracket is fixedly mounted at one end of the top of the oil pumping unit base, a walking beam is hinged to the top ofthe bracket, one end of the walking beam is fixedly connected with a horse head, a connecting rod is hinged to the bottom of the other end of the walking beam, a crank balancing block is hinged to thebottom end of the connecting rod, a supporting block is fixedly mounted in the middle of the top end of the oil pumping unit base, and a reduction gearbox is fixedly mounted at the top of the supporting block. According to the auxiliary adjustment device for the motor of the oil pumping unit and the operation method of the auxiliary adjustment device, through the joint action of a lead screw, a movable block and a second motor, when needing to be replaced, a belt is replaced without a special tool for demounting a first motor, the belt of the oil pumping unit can be replaced only by controlling forward and reverse rotation of the second motor through a PLC, thus a lot of time is saved, and meanwhile, the downtime of the oil pumping unit is shortened.

Description

technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to an auxiliary regulating device and an operation method for a motor of a pumping unit. Background technique [0002] The pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine". The pumping unit is the most important lifting equipment in the rod pumping system. Beamless pumping unit. [0003] When using the pumping unit to exploit the oil field, the belt of the pumping unit is the most vulnerable part. When the belt is damaged, the belt must be disassembled and replaced in time. When replacing the belt, the position of the motor needs to be changed to adjust the tightness of the belt so as to facilitate The belt is disassembled and replaced, and the motor of the existing pumping unit is fixedly installed on the base of the pumping unit through the fastening bolts and the motor base. To change the position of the motor...
