Description

Technical Field

[0001] The present invention relates to a pipe hanging device, and in particular to an intelligent mobile pipe hoisting device for oil pipeline laying. Background Art

[0002] When laying an oil pipeline at present, the oil pipeline is usually hoisted by a crane. When the existing crane hoists the oil pipeline, the oil pipeline is fixed by a rope. After the oil pipeline is hoisted, since the rope of the crane is made of a soft material, the oil pipeline is prone to shaking in the air after being hoisted, which will affect the placement accuracy of the oil pipeline. Moreover, when aligning the welding joints of two oil pipelines, it is mostly aligned and calibrated by manual observation, which easily leads to inaccurate alignment of the welding joints of the oil pipeline, resulting in deviation of the oil pipeline welding, so that the welded oil pipeline cannot be used and needs to be disassembled, thus wasting resources.

[0036] The balance mechanism 7 includes an electric push rod 701, a sliding sleeve 702, a lifting frame 703, an arc-shaped block 704, a ninth hydraulic cylinder 705, a third mounting plate 706, an L-shaped plate 707, a laser rangefinder 708, and a control module 709. The electric push rods 701 are installed at the front and rear parts of the first mounting plate 603. The electric push rods 701 on the front and rear sides are located inside the second sliding grooves 610 on the front and rear sides. The telescopic end of the electric push rod 701 is installed with a sliding sleeve 702. The sliding sleeve 702 is arranged in a sliding manner with the second sliding groove 610. A lifting frame 703 is slidably arranged inside the sliding sleeve 702. An arc-shaped block 704 is arranged at the lower part of the lifting frame 703. The outer walls of the sliding sleeves 702 on the front and rear sides are both installed with ninth hydraulic cylinders 705. The telescopic end of the ninth hydraulic cylinder 705 is fixedly connected to the lifting frame 703. The outer walls of the sliding sleeves 702 on the front and rear sides are both installed with third mounting plates 706. The third mounting plate 706 is located below the sliding sleeve 702. Three L-shaped plates 707 are equidistantly arranged at the bottom of the third mounting plate 706. A laser rangefinder 708 is arranged at the lower part of the L-shaped plate 707. The control module 709 is arranged at the top of the lifting frame 703. The control module 709, the third hydraulic cylinder 604, and the fourth hydraulic cylinder 605 are all electrically connected to the control device.

[0037] When welding the oil pipeline 29 is required, the user starts the third hydraulic cylinder 604 to swing the fixed plate 602 to the right or left to a suitable position and then closes it. Subsequently, the fourth hydraulic cylinders 605 on the front and rear sides are started to work, so that the first mounting plate 603 swings forward or backward to a suitable position, and the fourth hydraulic cylinder 605 is closed. The user starts the seventh hydraulic cylinder 627 to move the second ratchet plate 623 upward away from the first ratchet plate 621, and the return spring 624 is compressed accordingly, thus releasing the fixation of the first ratchet plate 621. Subsequently, the user closes the seventh hydraulic cylinder 627. Then, the user starts the telescopic end of the sixth hydraulic cylinder 619 to extend outward, so that the connecting plates 617 on the left and right sides move away from each other. The connecting plates 617 on the left and right sides moving away from each other causes the T-shaped sliding plates 616 on the left and right sides to move away from each other. The T-shaped sliding plates 616 on the left and right sides moving away from each other causes the first clamping blocks 628 on the left and right sides to move away from each other. When the first clamping blocks 628 on the left and right sides move away from each other to a suitable position, the user closes the sixth hydraulic cylinder 619 and starts the eighth hydraulic cylinder 629 to move the second clamping block 630 downward to a suitable position and then closes it. Then, the user starts the electric push rods 701 on the front and rear sides to move the sliding sleeves 702 on the front and rear sides outward to a suitable position and then closes them. At this time, the oil pipeline 29 is located inside the lifting frames 703 on the front and rear sides. Then, the user starts the ninth hydraulic cylinder 705 to move the lifting frames 703 downward. The lifting frames 703 moving downward causes the arc-shaped blocks 704 to move downward to a suitable position. Then, the user starts the electric push rods 701 on the front and rear sides to move the sliding sleeves 702 on the front and rear sides inward, so that the arc-shaped blocks 704 on the front and rear sides move into the oil pipeline 29. Subsequently, the electric push rod 701 is closed, and the ninth hydraulic cylinder 705 is started to move the arc-shaped block 704 upward through the lifting frame 703. The arc-shaped block 704 moving upward causes the oil pipeline 29 to move upward. When the oil pipeline 29 moves upward between the first clamping block 628 and the second clamping block 630, the user closes the ninth hydraulic cylinder 705 and starts the eighth hydraulic cylinder 629 to move the second clamping block 630 upward, so as to fix the oil pipeline 29 through the first clamping block 628 and the second clamping block 630. After the oil pipeline 29 is fixed, the user closes the eighth hydraulic cylinder 629 and starts the seventh hydraulic cylinder 627 to move the second ratchet plate 623 downward to reset and then closes it. The second ratchet plate 623 then cooperates with the first ratchet plate 621, thus fixing the position of the first ratchet plate 621, and then fixing the positions of the first clamping block 628 and the second clamping block 630, thereby preventing the first clamping block 628 and the second clamping block 630 from moving by themselves, which causes inconvenience to the fixation of the oil pipeline 29. When the oil pipeline 29 is fixed, subsequently, the user operates this equipment to move the oil pipeline 29 to the position where welding is required and aligns and docks the oil pipeline 29 with the welding place. At this time, the laser rangefinder 708 works to measure the height distance between the welding place and the oil pipeline 29 and feeds it back to the control equipment through the control module 709. Subsequently, the user, according to the feedback data,The control device is used to start the third hydraulic cylinder 604 and the fourth hydraulic cylinder 605 to finely adjust the angle of the oil pipeline 29 so that the oil pipeline 29 is aligned with the welding joint. Subsequently, the user welds the oil pipeline 29. After the welding of the oil pipeline 29 is completed, the user repeats the above operation to move the first clamping blocks 628 on the front and rear sides away from each other, thus releasing the fixation of the oil pipeline 29.

One end of the first torsion spring 16 is fixedly connected to the first rotating shaft 14, and the other end of the first torsion spring 16 is fixedly connected to the rotating plate 13. An arc-shaped plate 17 is installed between two adjacent second fixing blocks 15. The arc-shaped plate 17 is provided with an anti-slip component.

[0040] The anti-slip component includes a third fixing block 18, a fixing rod 19, a rotating sleeve 20, a second torsion spring 21, a rotating roller 22 and a grinding belt 23. Two third fixing blocks 18 are fixedly connected to the upper and lower parts of the inner walls of the arc-shaped plates 17 on the front and rear sides. A fixing rod 19 is rotatably installed between two adjacent third fixing blocks 18. A rotating sleeve 20 is rotatably provided in the middle part of the fixing rod 19. A second torsion spring 21 is sleeved on the outer side of the fixing rod 19. One end of the second torsion spring 21 is fixedly connected to the fixing rod 19, and the other end of the second torsion spring 21 is fixedly connected to the rotating sleeve 20. Rotating rollers 22 are rotatably installed on the upper and lower parts of the arc-shaped plate 17. A grinding belt 23 is wound between two adjacent rotating sleeves 20. The grinding belt 23 bypasses the adjacent rotating rollers 22, and the grinding belt 23 passes through the arc-shaped plate 17.

[0041] When welding the oil pipeline 29, the user moves the equipment with the oil pipeline 29 suspended to the position where welding is required, and adjusts and aligns the height distance between the welding point and the oil pipeline 29. Subsequently, the user starts the servo motors 8 on the front and rear sides to respectively rotate the first bevel gears 9 on the left and right sides outward. The second bevel gears 12 on the left and right sides then rotate inward. Through the rotating blocks 11 on the left and right sides, the rotating plates 13 on the left and right sides rotate inward. The inward rotation of the rotating plates 13 on the left and right sides, through the second fixing blocks 15 on the left and right sides, respectively causes the arc-shaped plates 17 on the left and right sides to swing inward. The inward swing of the arc-shaped plates 17 on the left and right sides causes the abrasive belts 23 on the left and right sides to swing inward. When the abrasive belts 23 on the left and right sides are both in contact with the oil pipeline 29, the abrasive belts 23 on the left and right sides continue to swing inward, so that the rotating sleeves 20 on the upper and lower sides release the abrasive belts 23, and the second torsion springs 21 are tightened accordingly. When the abrasive belts 23 on the left and right sides are in close contact with the oil pipeline 29, the arc-shaped plates 17 on the left and right sides continue to swing inward, so that the arc-shaped plates 17 on the left and right sides swing, and the first torsion springs 16 are tightened accordingly, thus clamping and fixing the oil pipeline 29. Subsequently, the user performs welding work on the oil pipeline 29. After the welding work, the user starts the servo motors 8 on the left and right sides to respectively rotate the first bevel gears 9 on the left and right sides inward, so that the arc-shaped plates 17 on the left and right sides swing outward to reset. When the arc-shaped plates 17 on the left and right sides swing outward to reset, the user turns off the servo motors 8. At this time, under the action of the first torsion springs 16, the arc-shaped plates 17 rotate to reset, and at the same time, under the action of the second torsion springs 21, the abrasive belts 23 are retracted.

[0042] As Figure 11 and Figure 12 shown, it further includes a fourth fixing block 24, a second rotating shaft 25, a swing frame 26, a clamping block 27, and a tenth hydraulic cylinder 28. Two fourth fixing blocks 24 are fixedly connected to the front and rear parts of the bottom surface of the first mounting plate 603. A second rotating shaft 25 is rotatably installed between two adjacent fourth fixing blocks 24 on the left and right. A swing frame 26 is provided in the middle of the second rotating shaft 25. A clamping block 27 is rotatably provided at the lower part of the swing frame 26. An inwardly inclined groove is opened at the bottom of the clamping block 27. Tenth hydraulic cylinders 28 are rotatably provided at the front and rear parts of the bottom surface of the first mounting plate 603. The telescopic ends of the tenth hydraulic cylinders 28 on the front and rear sides are respectively rotatably connected to the tops of the swing frames 26 on the front and rear sides.

[0043] Before welding the oil pipeline 29 is required, the user starts the telescopic ends of the tenth hydraulic cylinders 28 to extend, so that the swing frames 26 swing downward, and the clamping blocks 27 swing downward accordingly. Since an inwardly inclined groove is opened at the bottom of the clamping block 27, the downward swing of the clamping block 27 facilitates the positioning of the oil pipeline 29, thus facilitating the cooperation of the first clamping blocks 628 and the second clamping blocks 630 on the left and right sides to clamp and fix the oil pipeline 29.

[0044] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
