[0014] During the frame processing stage, the vertical beam is processed by a machine tool, and two first pin holes are formed on one side of the end of the vertical beam along the first direction, which are spaced apart along the second direction; wherein, the second direction is perpendicular to the first direction and is located in the same horizontal plane;

[0015] During the beam machining stage, the beam is machined by a machine tool to form a second pin hole that passes through the beam laterally.

[0016] During the skid assembly stage, the end of the crossbeam is inserted into the gap of the first pin hole so that the first pin hole and the second pin hole align one-to-one.

[0017] In one embodiment, the hydraulic cylinder guide channel is open at its top end along the height direction to form a guide hole, and the processing method includes:

[0018] During the frame manufacturing stage, the vertical beams are machined using a machine tool so that the guide holes of each vertical beam are located in the same horizontal plane after the skid is assembled.

[0019] In one embodiment, the sheet frame includes two vertical beams spaced apart along a second direction, the pry bar includes four horizontal beams, a horizontal beam is disposed between the top ends of the two vertical beams spaced apart along the first direction, and a horizontal beam is disposed between the bottom ends of the two vertical beams spaced apart along the first direction; wherein, the second direction is perpendicular to the first direction and lies in the same horizontal plane.

[0020] In one embodiment, the hydraulic cylinder guide channel is open at its top end along the height direction to form a guide hole, and the processing method includes:

[0021] During the frame processing stage, the vertical beams are processed by a machine tool so that the guide holes of each vertical beam of the sheet frame are spaced apart along the second direction, and the guide holes of two vertical beams spaced apart along the first direction are spaced apart along the first direction.

[0022] In one embodiment, the hydraulic cylinder guide channel is open at its top end along the height direction to form a guide hole, and the processing method includes:

[0023] During the frame processing stage, the end face of the vertical beam away from the guide hole is machined by a machine tool so that the end face of the vertical beam away from the guide hole is perpendicular to the axis of the vertical beam.

[0024] A second aspect of this application provides a pry bar for use in the processing method of any of the above-described pry bars.

This allows for independent processing of the plate-like frames, reducing the size of machined structural components, thereby reducing processing difficulty, facilitating manufacturing, and ultimately improving economic efficiency.

[0043] One embodiment of this application provides a method for manufacturing a skid 10. Please refer to [link / reference]. Figure 4 and Figure 12 The pry bar 10 includes a crossbeam 11 and two plate frames 12 spaced apart along a first direction. Each plate frame 12 includes a vertical beam 121 extending along the height direction. The manufacturing method includes the following steps:

[0044] Step S1: In the frame processing stage, the vertical beam 121 is processed by a machine tool to form an axially extending cylinder guide channel 121a in the vertical beam 121.

[0045] Step S2: During the skid assembly stage, the crossbeam 11 is welded to the vertical beam 121 for assembly with the plate frame 12.

[0046] Another embodiment of this application provides a skid 10, please refer to... Figure 4 The pry bar 10 is used in the processing method of the pry bar 10 described in any embodiment of this application. The pry bar 10 includes a crossbeam 11 and two plate frames 12 spaced apart along a first direction. The plate frames 12 include vertical beams 121 extending along the height direction. The crossbeam 11 is located at the interval of the plate frames 12, and the opposite ends of the crossbeam 11 are respectively connected to the two vertical beams 121. The vertical beam 121 has a hydraulic cylinder guide channel 121a extending along the axial direction.

[0047] Another embodiment of this application provides a tower; please refer to [link / reference]. Figures 1 to 3 The tower includes multiple telescopic cylinders 20 and multiple skids 10 as described in any embodiment of this application. Each skid 10 is arranged along the height direction. Along the height direction, adjacent skids 10 are vertically connected by telescopic cylinders 20. The telescopic cylinder 20 includes a support cylinder and a support cylinder rod. Between adjacent skids 10, one of the support cylinder and the support cylinder rod is located in the cylinder guide channel 121a of the bottom skid 10, and the other of the support cylinder and the support cylinder rod is mounted on the vertical beam 121 of the top skid 10.

[0048] Specifically, the tower in this application embodiment can be any type of tower. For ease of description, this application embodiment is described using a tower used in conjunction with a pipe string as an example.

[0049] The tower includes multiple skids 10 and multiple telescopic cylinders 20, with each skid 10 sequentially and movably connected along the height direction. Adjacent skids 10 are connected by at least one telescopic cylinder 20. Through the telescopic action of the telescopic cylinder 20, the top skid 10 relative to the bottom skid 10 can be raised or lowered.

[0050] The cylinder guide channel 121a of the skid 10 is used to install the telescopic cylinder 20. This greatly improves the installation stability of the telescopic cylinder 20 on the skid 10 and facilitates the transfer of load from the top skid 10 to the vertical beam 121 of the bottom skid 10.

[0051] Between adjacent skids 10, the hydraulic cylinder guide channel 121a of the skid 10 with the support cylinder located on the bottom side can be used, and the support cylinder rod is installed on the vertical beam 121 of the skid 10 located on the top side, that is, the telescopic hydraulic cylinder 20 is installed in an upright manner.

[0052] Depending on the actual situation, the support cylinder rod can also be located in the cylinder guide channel 121a of the bottom skid 10, and the support cylinder barrel can be installed on the vertical beam 121 of the top skid 10, that is, the telescopic cylinder 20 is installed in an inverted manner. This can further improve the connection stability between the telescopic cylinder 20 and the top skid 10, making it easier for the top skid 10 to transfer the load to the telescopic cylinder 20, and then to the vertical beam 121 of the bottom skid 10.

[0053] The skid 10 is a frame structure, which includes a crossbeam 11 and two plate frames 12.

[0054] Among them, the plate frame 12 is a plate structure. The crossbeam 11 of the skid 10 and the plate frame 12 are processed independently, which can greatly reduce the size of the workpiece to be processed by the machine tool, thus making it easier to process.

[0055] When the tower is in the installation state, the vertical beam 121 of the plate frame 12 extends along the height direction, the two plate frames 12 are spaced apart along the first direction, and the two plate frames 12 are connected by the cross beam 11.

[0056] It should be noted that the cylinder guide channel 121a of the vertical beam 121 extends along the axial direction of the vertical beam 121. In fact, when the tower is in the installation state, the axial direction of the vertical beam 121 is the height direction, so the cylinder guide channel 121a also extends along the height direction.

[0057] The frame processing stage is the stage of machining the plate frame 12 on a machine tool, and the skid assembly stage is the structure of assembling the crossbeam 11 and the plate frame 12. It can be understood that the frame processing stage is located before the skid assembly stage.

[0058] During the manufacturing process, before welding and assembling the plate frame 12 and the crossbeam 11, the vertical beam 121 of the plate frame 12 is machined separately using a machine tool. This facilitates the machining of the plate frame 12, thereby forming the hydraulic cylinder guide channel 121a. This avoids the problem of needing a larger machine tool to machine the skid 10, which would be inconvenient if the vertical beam 121 is machined after welding and assembling the plate frame 12 and the crossbeam 11.

[0059] The processing method of the skid 10 in this embodiment involves machining the vertical beam 121 using a machine tool during the frame processing stage to form an axially extending hydraulic cylinder guide channel 121a within the vertical beam 121. During the skid assembly stage, the horizontal beam 11 is welded to the vertical beam 121 for assembly with the sheet frame 12. Therefore, machining the vertical beam 121 before welding the horizontal beam 11 to the vertical beam 121 avoids the increased processing difficulty that would occur if the entire skid 10 frame were too large during overall manufacturing after assembly. This allows for independent processing of the sheet frame 12, reducing the size of machined structural components, thereby lowering processing difficulty, facilitating manufacturing, and ultimately improving economic efficiency.

[0060] In addition, by machining the vertical beam 121 with a machine tool to form the cylinder guide channel 121a, the accuracy of the cylinder guide channel 121a extending along the axial direction of the vertical beam 121 can be greatly improved, and the cylinder guide channel 121a can have high dimensional accuracy and positional accuracy.

[0061] In one embodiment, prior to the skid assembly stage, the processing method further includes a crossbeam processing stage, and the processing method further includes the following steps:

[0062] During the frame processing stage, the vertical beam 121 is processed by a machine tool to form a first pin hole 121b on one side of the end of the vertical beam 121 along the first direction.

[0063] During the beam machining stage, the beam 11 is machined by a machine tool to form second pin holes 11a at opposite ends of the beam 11.

[0064] During the skid assembly stage, the first pin hole 121b and the second pin hole 11a are aligned one by one, and the pins are passed through the first pin hole 121b and the second pin hole 11a so that the guide channels 121a of each cylinder extend along the height direction.

[0065] Specifically, both the frame processing stage and the crossbeam processing stage are located before the skid assembly stage, but the order between the frame processing stage and the crossbeam processing stage is not limited. That is, the frame processing stage can be located before the crossbeam processing stage, or the crossbeam processing stage can be located before the frame processing stage, or the frame processing stage and the crossbeam processing stage can be carried out simultaneously.

[0066] The beam machining stage involves machining the beam 11 using machine tools. Before assembling the skid 10, the beam 11 and the plate frame 12 are separate, independent components. Machining the beam 11 and the plate frame 12 separately improves machining convenience.

[0067] During the frame machining stage, on the one hand, the vertical beam 121 needs to be machined using a machine tool to form the hydraulic cylinder guide channel 121a. On the other hand, the vertical beam 121 also needs to be machined using a machine tool to form the first pin hole 121b.

[0068] It should be noted that the order in which the first pin hole 121b is machined and the hydraulic cylinder guide channel 121a is not limited. The first pin hole 121b can be machined first, followed by the hydraulic cylinder guide channel 121a. Alternatively, the hydraulic cylinder guide channel 121a can be machined first, followed by the first pin hole 121b.

[0069] The first pin hole 121b is located on one side of the end of the vertical beam 121 along the first direction. In fact, when the tower is in the installed state, the first pin hole 121b is located on the side of the vertical beams 121 of the two-piece frame 12 that are close to each other. Simultaneously, by machining the second pin hole 11a at the end of the crossbeam 11, a pin can be inserted through the aligned first pin hole 121b and the second pin hole 11a during the skid assembly stage. On one hand, this allows the crossbeam 11 to be connected to the plate frame 12, facilitating welding the crossbeam 11 to the vertical beam 121. On the other hand, by using the first pin hole 121b, the second pin hole 11a, and the pin to engage, the positions of the crossbeam 11 and the vertical beam 121 can be fixed. That is, when the first pin hole 121b and the second pin hole 11a are aligned and connected, the crossbeam 11 can be positioned in a set position to facilitate welding the crossbeam 11 to the vertical beam 121. Meanwhile, since the pry bar 10 includes two plate frames 12, after the two ends of the crossbeam 11 are respectively connected to the vertical beams 121 of the two plate frames 12 through pins, the positions of the two plate frames 12 can be positioned, thereby ensuring that the hydraulic cylinder guide channels 121a of the two plate frames 12 can extend along the height direction, which can greatly improve the machining accuracy of the pry bar 10 and reduce the machining error of the pry bar 10.

[0070] During the skid assembly stage, the second pin holes 11a at both ends of the crossbeam 11 are aligned one by one with the first pin holes 121b of the vertical beam 121 of a plate frame 12, thereby enabling the positioning of the two plate frames 12.

[0071] In fact, during the skid assembly stage, the first pin hole 121b and the second pin hole 11a should be aligned one by one and the pins should be installed before the crossbeam 11 is welded to the vertical beam 121.

[0072] In one embodiment, please refer to Figure 5 , Figures 8 to 11The end of the vertical beam 121 has a first pin hole 121b on one side along the first direction, and the opposite ends of the horizontal beam 11 have second pin holes 11a. The horizontal beam 11 and the vertical beam 121 are connected by pins passing through the first pin hole 121b and the second pin hole 11a.

[0073] In one embodiment, the processing method includes the following steps:

[0074] During the frame processing stage, the vertical beam 121 is processed by a machine tool. Two first pin holes 121b are formed at one side of the end of the vertical beam 121 along the first direction. The second direction is perpendicular to the first direction and is located in the same horizontal plane.

[0075] During the beam machining stage, the beam 11 is machined by a machine tool to form a second pin hole 11a that runs transversely through the beam 11.

[0076] During the skid assembly stage, the end of the crossbeam 11 is inserted into the gap of the first pin hole 121b so that the first pin hole 121b and the second pin hole 11a are aligned one by one.

[0077] Specifically, by machining two spaced first pin holes 121b, the second pin hole 11a of the crossbeam 11 can be installed at the space between the first pin holes 121b, thereby facilitating the connection between the second pin hole 11a and the first pin hole 121b, and thus improving the installation stability of the crossbeam 11 and the vertical beam 121.

[0078] The second pin hole 11a extends transversely through the crossbeam 11. In fact, the second pin hole 11a also extends along the second direction. Thus, when the crossbeam 11 is engaged with the gap of the first pin hole 121b, the two opposite sides of the second pin hole 11a along the second direction will communicate with the first pin hole 121b, which facilitates the pin to pass through the first pin hole 121b, the second pin hole 11a, and the first pin hole 121b in sequence. This makes the connection between the crossbeam 11 and the vertical beam 121 more stable and allows for better positioning of the vertical beam 121.

[0079] It should be noted that by machining two spaced first pin holes 121b, the parallelism between the two first pin holes 121b can be ensured, thereby ensuring the perpendicularity of the crossbeam 11 axis to the first pin holes 121b.

[0080] In one embodiment, please refer to Figure 6 and Figure 9 The top of the hydraulic cylinder guide channel 121a is open along the height direction to form a guide hole 121c. The machining method includes the following steps:

[0081] During the frame processing stage, the vertical beams 121 are machined by machine tools so that the guide holes 121c of each vertical beam 121 are located in the same horizontal plane after the skid 10 is assembled.

[0082] Specifically, the hydraulic cylinder guide channel 121a is used to install the telescopic hydraulic cylinder 20, which extends and retracts through the guide hole 121c at the top. Thus, during the frame processing stage, by machining the vertical beam 121, it is ensured that each guide hole 121c is in the same horizontal plane, which guarantees the size and parallelism of each guide hole 121c of the same skid 10, making the installation and relative movement between adjacent skids 10 along the height direction of the tower more stable.

[0083] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 7 The sheet frame 12 includes two vertical beams 121 spaced apart along a second direction, and the pry bar 10 includes four horizontal beams 11. A horizontal beam 11 is provided between the top ends of the two vertical beams 121 spaced apart along a first direction, and a horizontal beam 11 is provided between the bottom ends of the two vertical beams 121 spaced apart along the first direction. The second direction is perpendicular to the first direction and lies in the same horizontal plane.

[0084] Specifically, each of the two sheet frames 12 has a vertical beam 121 on opposite sides along the second direction. Among the four vertical beams 121 of the two sheet frames 12, the top ends of the two vertical beams 121 spaced apart along the first direction are connected by a crossbeam 11, and the bottom ends are connected by a crossbeam 11.

[0085] In fact, the two vertical beams 121 of the sheet frame 12 are connected by the frame crossbeams 11, thus forming a rectangular frame structure.

[0086] It is understandable that since the skid 10 includes four vertical beams 121, the skid 10 also has four hydraulic cylinder guide channels 121a. During the frame processing stage, by machining the vertical beams 121 with a machine tool, the accuracy of the relative position of each hydraulic cylinder guide channel 121a and the parallelism between them can be improved.

[0087] In one embodiment, please refer to Figure 8 and Figure 9 The top of the hydraulic cylinder guide channel 121a is open along the height direction to form a guide hole 121c. The machining method includes the following steps:

[0088] During the frame processing stage, the vertical beams 121 are processed by a machine tool so that the guide holes 121c of each vertical beam 121 of the sheet frame 12 are spaced apart along the second direction, and the guide holes 121c of two vertical beams 121 spaced apart along the first direction are spaced apart along the first direction.

[0089] Specifically, during the frame processing stage, when machining the vertical beams 121, by determining the relative positional relationship between the guide holes 121c of each vertical beam 121, the spacing accuracy between the two vertical beams 121 of the plate frame 12 can be guaranteed. At the same time, the spacing accuracy between the vertical beams 121 of the two plate frames 12 can be guaranteed, which can greatly improve the accuracy of the relative position of each hydraulic cylinder guide channel 121a and the parallelism between them, thereby making the installation between adjacent skids 10 of the tower smoother and more stable.

[0090] In one embodiment, the top end of the hydraulic cylinder guide channel 121a is open along the height direction to form a guide hole 121c, and the processing method includes the following steps:

[0091] During the frame processing stage, the end face of the vertical beam 121 away from the guide hole 121c is machined by a machine tool so that the end face of the vertical beam 121 away from the guide hole 121c is perpendicular to the axis of the vertical beam 121.

[0092] Specifically, during the frame processing stage, when machining the vertical beams 121, the bottom end faces of the vertical beams 121 are machined to ensure that the bottom end faces of each vertical beam 121 are horizontal, thus guaranteeing the vertical accuracy of the telescopic cylinder 20 installation.
