Description

Technical Field

[0001] The present invention belongs to the technical field of wellhead hoisting, and particularly relates to an intelligent hoisting device for a simulated well wellhead. Background Art

[0002] In the fields of resource extraction such as oil, natural gas, and minerals, the wellhead hoisting device is one of the core equipment, which is used to complete operations such as hoisting, lowering, and positioning of downhole equipment, tools, or objects. With the increase in the depth of resource extraction and the complexity of the operating environment, the performance requirements for wellhead hoisting devices are also getting higher and higher. Traditional wellhead hoisting devices have many limitations in practical applications. For example, the support range is limited, the traction force distribution is uneven, and the adaptability is poor. It is difficult to meet the high efficiency and safety requirements of modern mining operations;

[0003] A single support structure is difficult to provide sufficient support range and stability, resulting in easy shaking or tilting during the hoisting process, increasing safety hazards. Traditional devices usually adopt the design of a single traction motor and traction rope, resulting in the concentration of the traction force at a certain point, which is easy to cause equipment overload or damage, and at the same time reduces the hoisting efficiency. The adjustment range of the guiding component of the traditional device is limited and cannot effectively adapt to wellheads of different diameters, resulting in a large deviation in the position of the traction rope during the hoisting process, affecting the operation accuracy and safety. For this reason, we designed an intelligent hoisting device for a simulated well wellhead to provide another technical solution for the above technical problems. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1-8 , an intelligent hoisting device for the wellhead of a simulated well, including a circular base 1, a simulated pipe well 2 is fixed inside the circular base 1, a plurality of first rectangular bases 4 are evenly arranged on the outer side of the top of the circular base 1, a vertical column 3 is fixed on the top of the first rectangular base 4, a second rectangular base 5 is arranged at one end of the first rectangular base 4, and a first driven roller 8 is arranged on the top of the vertical column 3;

[0031] A moving mechanism for moving the second rectangular base 5 is arranged at the bottom of the outer side of the vertical column 3, and a support mechanism for guiding the traction rope is also arranged at the top of the outer side of the vertical column 3;

[0032] A circular fixing ring 15 is also arranged on the top of the circular base 1, the vertical column 3 passes through the inside of the circular fixing ring 15 and is fixedly connected to the circular fixing ring 15. Through the arrangement of the circular fixing ring 15, it is possible to fix a plurality of vertical columns 3, so as to facilitate the stability between the plurality of vertical columns 3;

[0033] The moving mechanism includes a vertical hydraulic cylinder 11. The vertical hydraulic cylinder 11 is fixed to the top of the first rectangular base 4. The output end of the vertical hydraulic cylinder 11 is fixed with a vertical lifting plate 12. The vertical lifting plate 12 penetrates through the inside of the vertical column 3 and is slidably connected to the vertical column 3. One end of the vertical lifting plate 12 is rotatably connected to an inclined rotating plate 13. The bottom of the inclined rotating plate 13 is rotatably connected to the second rectangular base 5 through a pin shaft. A guiding component is also arranged between the first rectangular base 4 and the second rectangular base 5;

[0034] A circular through-hole is formed inside the vertical lifting plate 12. The vertical column 3 is located inside the circular through-hole and is slidably connected to the vertical lifting plate 12 through the circular through-hole. Thus, the vertical lifting plate 12 can vertically slide on the outside of the vertical column 3. The setting of the vertical column 3 can guide the vertical lifting track of the vertical lifting plate 12;

[0035] The guiding component includes a longitudinal optical rod 19. The longitudinal optical rod 19 is fixed inside both the first rectangular base 4 and the second rectangular base 5. Both ends on the outside of the longitudinal optical rod 19 are slidably connected with longitudinal sliding blocks 20. A rectangular rotating rod 21 is rotatably connected between two longitudinally sliding blocks 20 arranged diagonally through a pin shaft;

[0036] The two rectangular rotating rods 21 are cross-designed, and the intersection of the two rectangular rotating rods 21 is rotatably connected through a pin shaft. Through the setting of the pin shaft, the two rectangular rotating rods 21 can rotate around the pin shaft as the center. Through the rotation of the two rectangular rotating rods 21, the second rectangular base 5 can move at one end of the first rectangular base 4;

[0037] A longitudinal through-hole is formed inside the longitudinal sliding block 20. The longitudinal optical rod 19 is located inside the longitudinal through-hole and is slidably connected to the longitudinal sliding block 20 through the longitudinal through-hole. Through the setting of the longitudinal through-hole, the longitudinal sliding block 20 can longitudinally slide on the outside of the longitudinal optical rod 19. Through the movement of the two longitudinal sliding blocks 20, the distance between the first rectangular base 4 and the second rectangular base 5 can be adjusted. Thus, the operation of the vertical hydraulic cylinder 11 can drive the second rectangular base 5 to move;

[0038] Here, after multiple first rectangular bases 4 are erected on the top of the circular base 1, the operation of the vertical hydraulic cylinder 11 enables the vertical lifting plate 12 to slide vertically. The sliding of the vertical lifting plate 12 causes the second rectangular base 5 to move away from one end of the first rectangular base 4 through the inclined rotating plate 13. During this process, the two longitudinal sliding blocks 20 can slide outside the longitudinal optical rod 19, so that the two rectangular rotating rods 21 can rotate around the pin shaft at the intersection of the rectangular rotating rods 21, enabling the second rectangular base 5 to move at one end of the first rectangular base 4, thereby enabling the support position of the second rectangular base 5 to be adjusted. The movement of the second rectangular base 5 can improve the support stability of the device;

[0039] The support mechanism includes a first rotating seat 22 and a second rotating seat 23. The top of the first rotating seat 22 is rotatably connected to an inclined hydraulic cylinder 24 through a pin shaft. The output end of the inclined hydraulic cylinder 24 is rotatably connected to an inclined support column 14 through a pin shaft. The top of the inclined support column 14 is rotatably connected to the second rotating seat 23 through a pin shaft. The bottom of the inclined support column 14 is rotatably connected to a second driven roller 9 through a pin shaft. A limiting mechanism for restricting the movement of the first rotating seat 22 and the second rotating seat 23 is also provided outside the vertical column 3;

[0040] A traction motor 6 is bolted to the top of the second rectangular base 5. The output end of the traction motor 6 is fixed with a traction roller 7. A traction head 10 is arranged inside the simulated pipe well 2. A traction rope is arranged outside the traction roller 7. The traction rope bypasses the outside of the first driven roller 8 and the second driven roller 9, and the traction rope is fixedly connected to the traction head 10. Through the operation of the traction motor 6, the traction roller 7 can rotate. The rotation of the traction roller 7 enables the traction head 10 to vertically lift inside the simulated pipe well 2 through the arrangement of the traction rope;

[0041] Here, the operation of the inclined hydraulic cylinder 24 enables the inclined support column 14 to rotate around the connection point between the second rotating seat 23 and the inclined support column 14, so that the second driven roller 9 can rotate at an angle around the connection point between the second rotating seat 23 and the inclined support column 14, enabling the second driven roller 9 to rotate to the top of the simulated pipe well 2 to adapt to simulated pipe wells 2 with different diameters and improve the applicability of the device;

[0042] The limiting mechanism includes two sleeve components. Sleeve components are fixed to one end of the second rotating seat 23 and the first rotating seat 22 and are located outside the vertical column 3. The sleeve component is composed of two symmetrically designed arc-shaped connecting pipes 25. A vertical rectangular plate 16 is arranged on one side of the vertical column 3. Longitudinal I-beams 17 are fixed to the top and bottom of the vertical rectangular plate 16. A longitudinal rigid spring 18 is arranged between the vertical column 3 and the vertical rectangular plate 16;

[0043] The longitudinal I-beam 17 passes through the interior of the vertical column 3 and is slidably connected with the vertical column 3. A limiting groove adapted to the longitudinal I-beam 17 is provided inside the arc-shaped connecting tube 25. The arc-shaped connecting tube 25 and the longitudinal I-beam 17 are matched through the limiting groove clearance. Through the setting of the limiting groove, the longitudinal I-beam 17 can move out of the arc-shaped connecting tube 25, and then the longitudinal I-beam 17 can release the restriction on the arc-shaped connecting tube 25, so that the two arc-shaped connecting tubes 25 can be disassembled outside the vertical column 3, so as to guide the disassembly of the mechanism;

[0044] Here, when the support mechanism needs to be disassembled, the vertical rectangular plate 16 is pulled in the direction away from the vertical column 3. The pulling of the vertical rectangular plate 16 enables the longitudinal I-beam 17 to slide inside the vertical column 3, so that the longitudinal rigid spring 18 is deformed under force, and then the longitudinal I-beam 17 can move out of the two arc-shaped connecting tubes 25, so that the longitudinal I-beam 17 can release the restriction on the two arc-shaped connecting tubes 25, so that the two arc-shaped connecting tubes 25 can be disassembled, and then the support mechanism can be disassembled.

[0045] Working principle: After a plurality of first rectangular bases 4 are erected on the top of the circular base 1, the operation of the vertical hydraulic cylinder 11 enables the vertical lifting plate 12 to slide vertically, and the sliding of the vertical lifting plate 12 enables the second rectangular base 5 to move away from one end of the first rectangular base 4 through the oblique rotating plate 13. In this process, the two longitudinal sliding blocks 20 can slide on the outside of the longitudinal light rod 19, so that the two rectangular rotating rods 21 can rotate with the pin shaft at the intersection of the rectangular rotating rods 21 as the center of the circle, so that the second rectangular base 5 can move at one end of the first rectangular base 4, so that the support of the second rectangular base 5 The position can be adjusted, and the stability of the support of the device can be improved by moving the second rectangular base 5. By setting multiple first rectangular bases 4 and movable second rectangular bases 5, the support range of the device is expanded, the shaking or tilting that may occur during the hoisting process is reduced, and the potential safety hazards are reduced. A traction motor 6 is set on the multiple movable second rectangular bases 5, and a first driven roller 8 is set on the top of the vertical column 3, so that the traction rope can evenly distribute the traction force, avoiding the limitations of the traditional single traction motor 6 and traction rope, effectively sharing the load during the hoisting process, and significantly improving the lifting capacity of the device, which is suitable for hoisting heavier objects in the well;

[0046] The operation of the diagonal hydraulic cylinder 24 enables the diagonal support column 14 to rotate around the connection between the second rotating seat 23 and the diagonal support column 14, and further enables the second driven roller 9 to rotate at an angle around the connection between the second rotating seat 23 and the diagonal support column 14, so that the second driven roller 9 can rotate to the top of the simulated pipe shaft 2 to adapt to simulated pipe shafts 2 of different diameters, enhancing the versatility of the device, meeting the hoisting requirements in various simulated pipe shaft 2 environments, reducing the frequency of equipment replacement or adjustment, and improving work efficiency;

[0047] When the support mechanism needs to be disassembled, the vertical rectangular plate 16 is pulled in a direction away from the vertical column 3. The pulling of the vertical rectangular plate 16 enables the longitudinal I-beam 17 to slide inside the vertical column 3, causing the longitudinal rigid spring 18 to deform under force. Further, the longitudinal I-beam 17 can move out of the inside of the two arc-shaped connecting pipes 25, and then the longitudinal I-beam 17 can release the restriction on the two arc-shaped connecting pipes 25, enabling the two arc-shaped connecting pipes 25 to be disassembled, and further enabling the support mechanism to be disassembled;

[0048] The control of the traction motor 6 can achieve precise adjustment of the hoisting process, avoiding errors and risks in traditional manual operations. The collaborative work of multiple traction motors 6 further improves the safety and reliability of the hoisting process.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
