Steel rope oil pumping unit for oil exploitation

Abstract

The invention relates to the technical field of oil pumping units, and discloses a steel rope oil pumping unit for oil exploitation. The steel rope oil pumping unit comprises a supporting seat and a base, wherein a fixing frame is fixedly arranged on the top surface of the supporting seat, a bearing is fixedly arranged in the middle of the fixing frame, the surface of the bearing is movably connected with a cross beam, a horse head is fixedly arranged on the right side surface of the cross beam, and a fixing sleeve is fixedly arranged at the right end of the cross beam. According to the steel rope oil pumping unit for oil exploitation, when the bearing is damaged, the cross beam can collapse downwards, then a switch of a first motor can be touched, then the first motor drives a second gear to rotate, a first threaded rod is driven to rotate through the meshing of the second gear and a first gear, the rotation of the first threaded rod can drive a limiting plate to move upwards to the top end of a first fixing rod, a sliding rod is limited, the sliding rod is prevented from moving downwards, at the moment, the first fixing rod and the sliding rod support the right end of the cross beam, the horse head is prevented from moving downwards and turning over, economic loss is avoided, and the safety of the device is improved.

Description

technical field [0001] The invention relates to the technical field of oil pumping units, in particular to a steel rope pumping unit for petroleum exploitation. Background technique [0002] At present, steel rope pumping units are widely used in mechanical oil production lifting equipment, and its quantity accounts for more than 80% of oil production lifting equipment in oil fields. Composed of , steel rope and rope hanger, the motor provides power for the reducer, drives the crank connecting rod mechanism to run, and the counterweight on the crank also rotates accordingly. [0003] Most of the existing steel rope pumping units are connected by bearings between the beam and the support. After a long period of operation, the top bearing is damaged. The oil machine stops working, and the donkey's head is overturned to the ground and on the one hand it will cause damage and cause economic losses, which reduces the safety performance of the device.

AI Technical Summary

Problems solved by technology

[0003] Most of the existing steel rope pumping units are connected by bearings between the beam and the bracket. After a long period of operation, the top bearing is damaged. The oil machine stops working, and the head of the donkey falls to the ground. On the one hand, it will cause damage and cause economic losses, which reduces the safety performance of the device.
