Beam-pumping unit support arm structure and application method thereof

Abstract

The invention discloses a beam-pumping unit support arm structure and an application method thereof. A support arm is included and arranged at the upper portion of a base. The support arm comprises afirst side frame, a second side frame and a transverse plate, the first side frame is fixed to one side of the bottom of the transverse plate, and the upper portion of the second side frame is rotationally arranged on the other side of the bottom of the transverse plate through a rotation rod. The second side frame comprises a first frame and a second frame, and the first frame is arranged at thebottom of the second frame. A baffle at the bottom of a fixing rod makes contact with the bottom of a limiting roller, the baffle cannot move upwards at the bottom of a penetrating hole, accordingly,the fixing rod and support arm cannot disengage from the upper portion of the base, and stability performance is good. Mounting and dismounting of the support arm from the upper portion of the base are convenient and fast. A drive motor rotates so that the position of the limiting roller can be adjusted, the beam-pumping unit support arm structure can adapt to fixing rods different in size, and connection between the fixing rod and an installing ring can be convenient. The support arm can be cyclically dismounted and mounted to be used many times, and the resource utilization rate is increased. Maintenance and replacement are simple in later support arm usage.

Description

technical field [0001] The invention relates to a support arm structure of a pumping unit, in particular to a support arm structure of a beam pumping unit and a using method thereof, belonging to the application field of the pumping unit. Background technique [0002] The beam pumping unit is a commonly used oil pumping machine in the process of oil extraction. The pumping machine includes a support arm structure to support the upper weight, so that the upper load-bearing beam can rotate normally, and then the oil inside the oil well to extract. [0003] But the existing beam pumping unit support arm structure still has certain deficiencies in use. The existing beam pumping unit support arm structure is simple in structure, and the bottom is often directly fixed to the ground during installation, and it is not easy to disassemble after fixing, and cannot be adjusted according to the actual working environment. After installation, it is difficult to move, and it cannot be d...
