A steel rope pumping unit for petroleum exploitation

Abstract

The invention relates to the technical field of pumping units, and discloses a steel rope pumping unit for oil exploitation, which includes a support seat and a base, a fixed frame is fixedly installed on the top surface of the support seat, and the middle part of the fixed frame is fixedly installed There is a bearing, the surface of the bearing is movably connected with a beam, the right side of the beam is fixedly equipped with a donkey head, and the right end of the beam is fixedly equipped with a fixed sleeve. The oil extraction uses a steel rope pumping unit. When the bearing is damaged, the beam will collapse downwards, and then it will touch the switch of the motor one, and then the motor one will drive the gear two to rotate, and the threaded rod one will be driven by the meshing of the gear two and the gear one. Rotate, the rotation of threaded rod 1 will drive the limit plate to move upwards to the top of fixed rod 1, limit the sliding rod and prevent the downward movement of the sliding rod. The head of the donkey moves downward and falls over, which avoids economic loss and improves the safety of the device.

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.
