Horse-head overturning device of walking-beam type oil pumping unit

Abstract

The invention discloses a horse-head overturning device of a walking-beam type oil pumping unit. The horse-head overturning device comprises an oil-pumping-machine horse head, an oil-pumping-machine walking beam, a motor, a horse-head pin seat and a horse-head pin, wherein the horse head is hinged to the walking beam by a pin shaft; the motor is arranged on the upper surface of the walking beam; the horse-head pin seat is fixed on the side surface of the horse head; the horse-head pin seat is matched with the horse-head pin; an output shaft of the motor is provided with a first gear; the upper end of the pin shaft is connected with a gear shaft of a second gear; the second gear is arranged on the other side surface of the horse head; and the first gear is meshed with the second gear. The horse-head overturning device disclosed by the invention has the beneficial effect that the motor is utilized for driving the horse head to overturn, so that the purpose of reducing the high-altitude operation of personnel is achieved; compared with the prior art, the horse-head overturning device disclosed by the invention has the advantages that the operation is simple, the use is safe, the workload of the personnel is reduced, and the like.

Description

technical field [0001] The invention relates to the field of oil production components, in particular to a donkey head turning device for a beam pumping unit. Background technique [0002] At present, most of the pumping units adopt the beam pumping unit, which has the advantages of simple structure, convenient operation, reliable operation, durability, and strong ability to apply to complex working conditions, but the shortcomings of the beam pumping unit are as follows: Before the construction, it is necessary to manually turn the donkey head to one side of the beam so that it does not hinder the operation of the hook running up and down. Smashing into the pin seat makes the donkey's head hang the load. During the operation of turning the donkey's head, the operator needs to operate at a high altitude, which has a large workload, high labor intensity and high risk factor. Contents of the invention [0003] The object of the present invention is to provide a donkey head ...
