Description

Technical Field

[0001] This utility model relates to an oil production equipment, or more precisely, a pumping unit wellhead elevation device. Background Technology

[0002] During the production process, for some pumping unit wellheads that have been in operation for a long time, it is necessary to replace the wellhead packing and replace the load cell battery section where the well height is too high.

[0003] Production practice has shown that the high operating height of pumping unit wellheads restricts operation, leading to situations where the height is insufficient for replacing wellhead packing load cell batteries in some wells, requiring the use of ladders or stools. In special cases, uneven ground can cause instability for personnel, necessitating multiple people to provide support, resulting in wasted manpower. Therefore, high wellheads generally require multiple people to replace wellhead packing or load cell batteries. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A pumping unit wellhead elevation device is characterized in that the pumping unit wellhead elevation device includes a main support, the tail of the main support is provided with a rectangular mesh frame, the mesh frame is provided with a steel mesh, the head of the main support is provided with a semi-cylindrical fixing clip, the fixing clip is provided with a rotatable semi-cylindrical movable clip, and the fixing clip is provided with a locking wrench.

[0006] In a preferred embodiment of the present invention, the main support includes a long strip-shaped main crossbeam and a long strip-shaped hollow main sleeve. The main crossbeam is telescopically disposed inside the main sleeve. The side wall of the main crossbeam is provided with a plurality of first positioning holes, and the side wall of the main sleeve is provided with a plurality of second positioning holes. The first positioning holes and the second positioning holes are fixedly connected by fastening bolts.

[0007] In a preferred embodiment of this utility model, the space frame is welded to the main support.

[0008] In a preferred embodiment of this utility model, the inner walls of the fixed clip and the movable clip are provided with anti-slip rubber sheets.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a pumping unit wellhead elevation device. The pumping unit wellhead elevation device is lightweight, easy to transport, and easy to process and manufacture. Compared with using A-frame ladders or benches, it does not require any manpower to hold it up, nor does it need to consider the flatness of the well site ground. It greatly reduces the number of maintenance personnel required and reduces the safety risks during the replacement of wellhead rubber or load cell batteries. Attached Figure Description

Detailed Implementation

[0012] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0013] like Figures 1 to 3As shown, the pumping unit wellhead elevation device includes a main support 10. The tail of the main support 10 is provided with a rectangular mesh frame 20, on which a steel mesh 30 is provided. The head of the main support 10 is provided with a semi-cylindrical fixing clip 40, on which a rotatable semi-cylindrical movable clip 50 is provided. The fixing clip 40 is provided with a locking wrench 60.

[0014] It should be noted that the space frame 20 is welded to the main support 10. In addition, the inner walls of the fixed clamp 40 and the movable clamp 50 are provided with anti-slip rubber sheets (not shown in the figure).

[0015] The working method of the wellhead elevation device of the pumping unit is explained below.

[0016] Connect the fixed clamp 40 and the movable clamp 50 to the oil pipe short connector, place anti-slip rubber pads on them, and tighten the locking wrench 60. In this way, the entire standing device is fixed to the oil pipe short connector.

[0017] Workers can now stand directly on the steel mesh 30 to replace the wellhead packing or the load cell battery. After the work is completed, unlock the locking wrench 60 and restore the equipment.

[0018] The pumping unit wellhead elevation device is lightweight, easy to transport, and easy to process and manufacture. Compared with using A-frame ladders or benches, it does not require any manpower to hold it up, nor does it need to consider the flatness of the well site. This greatly reduces the number of maintenance personnel required and reduces the safety risks during the replacement of wellhead rubber or load cell batteries.

[0019] like Figures 4 to 6 The image shows another embodiment of the pumping unit wellhead elevation device of this utility model.

[0020] The main support 10 includes a long strip-shaped main crossbeam 11 and a long strip-shaped hollow main sleeve 12. The main crossbeam 11 is telescopically disposed inside the main sleeve 12. The side wall of the main crossbeam 11 is provided with a plurality of first positioning holes 111, and the side wall of the main sleeve 12 is provided with a plurality of second positioning holes 122. The first positioning holes 111 and the second positioning holes 122 are fixedly connected by fastening bolts 13.
