Problems solved by technology

[0002] Most of the existing lever pumping units use a reducer to drive the beam to swing. The power of the motor driving the reducer is relatively large, and the weight of the whole machine is also very large. It is difficult to install and disassemble, and consumes a lot of power. At present, some oil cylinders are used to drive the beam. Swing, but the speed of the oil cylinder is slow, which directly leads to the reduction of the working efficiency of the pumping unit

Abstract

The invention provides an innovative energy-saving petroleum elevator and belongs to the technical field of lever-type pumping units. The innovative energy-saving petroleum elevator comprises a cross beam (3), a support (2), a sector part (5) and a steel wire rope (8), wherein the middle of the cross beam (3) is hinged to the upper end of the support (2), a balance weight mechanism is arranged at the rear end of the cross beam (3), the sector part (5) is fixed at the front end of the cross beam (3), the upper end of the steel wire rope (8) is fixedly connected with the sector part (5), an oil extraction rod connecting mechanism is arranged at the lower end of the steel wire rope (8), a lifting air cylinder (4) is arranged under the cross beam (3), the lower end of the lifting air cylinder (4) is hinged to the ground, and the upper end of the lifting air cylinder (4) is hinged to the cross beam (3) between the support (2) and the sector part (5). The lifting air cylinder drives the cross beam to vertically swing, the lifting air cylinder utilizes a balance weight block to drive the cross beam to swing with small force, the energy consumption of the lifting air cylinder is low, action frequency conversion is quick, the lifting air cylinder drives the cross beam to swing relative to a speed reducer, the innovative energy-saving petroleum elevator is simple in structure and convenient to install and dismount, and the whole machine weight is reduced.

Description

technical field [0001] An innovative energy-saving oil hoist belongs to the technical field of lever pumping units. Background technique [0002] Most of the existing lever pumping units use a reducer to drive the beam to swing. The power of the motor driving the reducer is relatively large, and the weight of the whole machine is also very large. It is difficult to install and disassemble, and consumes a lot of power. At present, some oil cylinders are used to drive the beam. Swing, but the speed of the oil cylinder is slow, which directly leads to the reduction of the working efficiency of the pumping unit. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an innovative energy-saving oil hoist with energy saving, light weight and simple structure. [0004] The technical solution adopted by the present invention to solve the technical problem is: the innovative energy...
