Problems solved by technology

It can be seen from the above-mentioned setting method that in the prior art, the donkey head is biased to one side of the beam.
[0004] And the current correction of the alignment problem between the steel wire rope and the polished rod is only to use a centralizer, and the effect of the centralizer is relatively poor

Abstract

The invention belongs to the technical field of petroleum field operation devices, and provides a beam-pumping unit device which is provided with a base, a supporting column, a driving motor and a reduction gearbox are fixed to the base, the driving motor is connected with the reduction gearbox through a belt, an output shaft of the reduction gearbox is connected with a crank, a balance block is arranged on the crank, and a connecting rod is hinged to the crank. The connecting rod is hinged with one end of the walking beam, the walking beam is rotatably supported on the support frame, the other end of the walking beam is fixedly provided with a horse head, the lower part of the horse head is connected with a beam hanger through a steel wire rope, the pumping unit is provided with a brake device, and the pumping unit is provided with a detachable steel wire rope guide assembly. The device has the following beneficial effects that the steel wire rope and the polished rod can be located on the same vertical line, the steel wire rope is supported by the multiple rolling wheels and protected, and long-term use cannot be affected due to direction change of the steel wire rope.

Description

technical field [0001] The invention belongs to the technical field of oil field operation devices, and in particular relates to a beam pumping unit device. Background technique [0002] The beam pumping unit is the type of pumping unit with the largest number and the widest distribution in the oil field. The donkey head of the oil machine is made of welded steel plates, and is matched with the forearm of the traveling beam through the donkey head pin. [0003] There are three connection modes of the donkey head and the traveling beam in the prior art: a rotating shaft type donkey head side rotation mechanism, a disassembled donkey head side rotation mechanism, and a donkey head side rotation mechanism with three pin shafts. It can be seen from the above arrangement that in the prior art, the donkey head is deflected to one side of the beam. [0004] Moreover, the alignment problem between the wire rope and the polished rod is currently corrected only by using a centralize...
