An adjusting member 139 is disposed on the connecting plate 138. The adjusting member 139 abuts against the crossbeam 142 and can play a role in supporting the crossbeam 142. The crossbeam 142 can rotate relative to the fixing rod 133. When the angle of the crossbeam 142 is not conducive to carrying the sucker rod or the tubing, the rotation angle of the crossbeam 142 can be adjusted by the adjusting member 139.

[0063] In practical applications, the adjusting member 139 can be an adjusting bolt. A threaded inner hole is provided on the connecting plate 138. The adjusting bolt is threadedly connected to the threaded inner hole. The adjusting bolt passes through the threaded inner hole from bottom to top and abuts against the crossbeam 142 above the connecting plate 138. Rotating the adjusting bolt can adjust the rotation angle of the crossbeam 142. An arc is provided at the top end of the adjusting bolt, and the arc matches the crossbeam 142.

[0064] In a specific embodiment, the workover process flow can be divided into the following steps:

[0065] First, build a tubing bridge or a sucker rod bridge at the workover construction site and build a tubing slideway.

[0066] Second, place the hydraulic lifting tubing pillow in the middle position between the tubing slideway and the wellhead. The tubing slideway and the hydraulic lifting tubing pillow are in a vertical state; connect the hydraulic source of the workover rig to the hydraulic controller on the hydraulic lifting tubing pillow with a high-pressure flexible pipeline.

[0067] Subsequently, when lowering the tubing or sucker rod into the well, operate the hydraulic controller on the hydraulic lifting tubing pillow to lower the moving crossbeam to the lowest point. The on-site operator then pushes the tubing or sucker rod above the moving crossbeam. Next, operate the hydraulic controller to lift multiple tubing or sucker rods to a height suitable for the wellhead personnel to operate. When pulling the tubing or sucker rod out of the well, operate the hydraulic controller to raise the moving crossbeam to a height suitable for the wellhead operator. As the tubing or sucker rod is pulled out, it will be arranged one by one on the rising moving crossbeam. When the moving crossbeam is full of tubing or sucker rods, operate the hydraulic controller to lower the moving crossbeam to the lowest point. The on-site operator then pushes the tubing or sucker rod away from the moving crossbeam, and then raises the moving crossbeam to a height suitable for the wellhead operator to continue the operation of pulling out the tubing or sucker rod.

[0068] Finally, after the workover is completed, operate the hydraulic controller to lower the moving crossbeam to the lowest point, hoist it to the next workover site, and continue to use it according to the above steps.

Certain features described in multiple embodiments within this specification can also be combined and implemented in a single embodiment. On the other hand, the various features described in a single embodiment can also be separately implemented in multiple embodiments or implemented in any suitable sub-combination. Additionally, although features may operate in certain combinations as described above and were even initially claimed as such, one or more features from the claimed combination can in some cases be removed from the combination, and the claimed combination can be directed to a sub-combination or a variation of the sub-combination.

[0071] Similarly, although the operations are depicted in a specific order in the drawings, this should not be construed as requiring these operations to be performed in the specific order shown or sequentially, or requiring all of the illustrated operations to be performed to achieve the desired result. In some cases, multitasking and parallel processing may be advantageous. Moreover, the separation of the various system modules and components in the above embodiments should not be construed as requiring such separation in all embodiments, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.

[0072] Accordingly, specific embodiments of the subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the acts recited in the claims can be performed in a different order and still achieve the desired result. In addition, the processes depicted in the figures are not necessarily in the particular order or sequential order shown to achieve the desired result. In some implementations, multitasking and parallel processing may be advantageous.

[0073] It should be noted that, in this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0074] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features claimed herein.
