Embodiment Construction

[0035] According to the present invention, with reference to the attached image 3 , which shows a pumping unit lever system comprising:

[0036] The main support 22 can be equivalent to the attached figure 2 The bracket shown in is mainly used as a fixed hinge support, that is, a mounting bracket for the hinge support;

[0037] The traveling beam 8, the middle part is installed on the top of the main bracket 22 through a hinge, forming a basic lever mechanism;

[0038] The donkey head 9 is arranged at one end of the beam, which is on the side of the sucker rod, connected to the sucker rod through the rope hanger 20, and the sucker rod is installed on the oil outlet tee at the wellhead through the wellhead packing seat;

[0039] It also includes:

[0040] Pull rod 28, the upper end of the pull rod is hinged to the other end of the beam. Of course, the pull rod also has the function of pushing. When the head of the donkey goes down, it needs to be driven by the pull rod. At...

Abstract

The invention discloses a lever system for a pumping unit. The lever system comprises a main support, a walking beam, a horse head, a pull rod hinged at the other end of the walking beam, a first drive device, a detecting device which is arranged on a stand for detecting upward or downward state of the pull rod, a rail formed at the pull rod side of the walking beam, a sliding seat matched with the rail to form a rail pair, a counter weight arranged on the sliding seat, and a second drive device for driving the sliding seat to run according to the pull rod state detected by the detecting device to ensure that the sliding seat is close to a constraint hinge when the pull rod moves upward and the sliding seat is far from the sliding seat when the pull rod moves downward, therefore, the lever system has small energy consumption and smaller output power of a power output part.

Description

technical field [0001] The invention relates to a lever system of an oil pumping unit. Background technique [0002] The widely used pumping unit at present is the beam pumping unit. Its main structure is a lever mechanism, which is called beam system in the industry. One end of the lever is the donkey head connected with the sucker rod, and the other end is the driving end. The pull rod is connected with a crank, and the end of the crank is provided with a relatively heavy counterweight, and the driving force of the lever is realized by using the different characteristics of the direction and magnitude of the force within the range of 360 degrees of the crank. For the pumping unit with this structure, the output power of each cycle of the crank rotation is basically unchanged, and it is always in a state of high power output, or in a state of high energy consumption. High energy consumption is also difficult to solve for this type of pumping unit. question. [0003] For t...
