Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and more particularly to a large-scale pipeline butt joint tool and a use method thereof. Background Art

[0002] Pipeline construction usually involves splicing multiple shorter pipes into a longer pipe to meet personalized needs. Conventional metal pipes are often connected by welding or flanges, and the docking installation process is relatively simple. However, due to the large diameter and heavy weight of large-diameter PCCP pipes, the socket docking operation is very difficult. At present, there is no special towing tool for the sealed docking of pipeline sections. The traditional method is to use a hand winch to dock. Generally, the two sections of the pipe are tied with a rope, and then the pulling force of the hand winch is used to complete the pipeline docking. This process is cumbersome, time-consuming, labor-intensive, and inefficient. At the same time, due to the uneven force on the socket, it is easy to cause the socket to be damaged, and it is very easy to pull off during docking, resulting in pipeline leakage.

[0044] The working principle and technical effects of the above technical solution are as follows:

After the docking cylinder is started, the support platform 2 3 is driven to approach or move away from the support platform 2. When the pipeline needs to be docked, the support platform 2 3 is pulled on the stand 5 to move in the direction of the support platform 2, so that the pipelines to be docked clamped in the two automatic centering and clamping devices 1 are docked. The docking accuracy is high, and the need for manual operation is reduced, which reduces the labor intensity. The entire automation process greatly improves the docking efficiency and shortens the construction time.

[0046] The automatic centering and clamping device 1 includes: a pipe rack structure 100, the pipe rack structure 100 is rotatably connected to the horizontal installation openings of two supporting frames 200, and the two supporting frames 200 are fixed to the support platform 1 2 or the support platform 2 3; the centering and clamping drive 300 installed on the pipe rack structure 100 is connected to a plurality of centering and clamping rollers 400 uniformly and slidably arranged on the side wall of the pipe rack structure 100, so as to drive the plurality of centering and clamping rollers 400 to synchronously move toward the axis of the pipe rack structure 100 to fix the pipe to be docked that passes through the pipe rack structure 100, or to synchronously move in a direction away from the axis of the pipe rack structure 100 to release the fixation of the pipe to be docked that passes through the pipe rack structure 100.

[0047] The pipe rack structure 100 in the automatic centering and clamping device 1 is rotatably connected with the horizontal installation openings of the two supporting frames 200. The positions of the multiple centering and clamping rollers 400 can be adjusted by rotating the pipe rack structure 100, thereby adjusting the positions of the multiple centering and clamping rollers 400 for tightening and fixing the pipes to be connected. The number of centering and clamping rollers 400 is not less than three, thereby ensuring the tightening and fixing effect. When centering and clamping is required, the centering and clamping drive 300 is controlled to start. The centering and clamping drive 300 can control the multiple centering and clamping rollers 400 to synchronously move toward the axis of the pipe rack structure 100 to fix the pipes to be connected that are inserted into the pipe rack structure 100, or to synchronously move in a direction away from the axis of the pipe rack structure 100 to release the fixation of the pipes to be connected that are inserted into the pipe rack structure 100. The advantages of the above technical solution are:

[0048] First, high-precision centering adjustment: by rotating the pipe rack structure 100, the positions of the multiple centering clamping rollers 400 can be flexibly adjusted to ensure that the centering clamping rollers 400 can accurately tighten and fix the butted pipes; the number of centering clamping rollers 400 is not less than three, and the tightening force can be evenly applied in multiple directions, effectively ensuring the centering accuracy and fixing effect, and avoiding pipe displacement or misalignment;

[0049] Second, flexible adjustment function: by rotating the pipe rack structure 100, the position of the centering clamping roller 400 can be quickly adjusted to adapt to the pipes to be connected of different sizes, shapes or materials, thereby improving the versatility and flexibility of the equipment; the centering clamping drive 300 can realize the synchronous movement of multiple centering clamping rollers 400, which can not only fix the pipe, but also quickly release the fixation, and the operation is simple and efficient; the synchronous movement design makes the process of fixing and releasing the pipe faster, reduces the operation time, and improves the work efficiency; multiple centering clamping rollers 400 work synchronously, which can evenly fix the pipe and avoid deformation or damage of the pipe caused by single-point fixation.

[0050] The centering clamping drive 300 includes: a clamping drive cylinder 301 installed on the outer wall of the pipe rack structure 100, the cylinder shaft of the clamping drive cylinder 301 is connected to a drive ring 302 slidably arranged outside the pipe rack structure 100, the drive ring 302 is connected to a plurality of drive slides 303 slidably arranged in the side grooves of the pipe rack structure 100, and a drive arm 304 is provided at one end of each drive slide 303 that penetrates into the pipe rack structure 100, and the plurality of drive arms 304 are connected to a plurality of centering clamping rollers 400. After the clamping drive cylinder 301 is started, the drive ring 302 can be controlled to slide on the outer surface of the pipe rack structure 100. When the drive ring 302 slides, it drives the multiple drive slides 303 to slide in the multiple side grooves of the pipe rack structure 100, thereby driving one end of the multiple drive arm rods 304 to move in the horizontal direction, and the other end of the multiple drive arm rods 304 drives the multiple centering clamping rollers 400 to move synchronously toward the axis of the pipe rack structure 100, or synchronously move in the direction away from the axis of the pipe rack structure 100; the drive ring 302 is connected to the pipe rack structure 100 through the multiple drive slides 303 to ensure that the multiple drive slides 303 can slide synchronously, thereby driving the multiple drive arm rods 304 to move synchronously; the multiple drive arm rods 304 are connected to the multiple centering clamping rollers 400 to ensure that the centering clamping rollers 400 can move synchronously toward the pipe rack structure 100 The frame structure 100 moves in the axial direction or away from the axial direction to achieve synchronous clamping or releasing of the pipeline; the synchronous movement design ensures that multiple centering clamping rollers 400 can evenly apply clamping force, avoids the pipeline from being offset or deformed due to uneven force, and improves the accuracy and stability of centering clamping; the driving ring 302 slides on the outside of the pipe rack structure 100, and the driving slide 303 slides in the side groove of the pipe rack structure 100. The overall structure is compact and occupies a small space; the driving arm 304 is connected to the driving ring 302 through the driving slide 303, and is connected to the centering clamping roller 400 by a rotation method, which reduces the complexity of the mechanical structure and improves space utilization; the flexible sliding and horizontal movement design enables the equipment to adapt to pipelines of different diameters and shapes, thereby improving the versatility and adjustability of the equipment.

[0051] The centering clamping roller 400 includes: a transmission connecting member 401 movably connected to the driving arm 304, the transmission connecting member 401 is connected to the arc-shaped clamping frame 402, and the two guide arm rods 403 fixed on the arc-shaped clamping frame 402 are both slidably arranged in the arm rod sliding hole of the pipe rack structure 100; the two ends of the arc-shaped clamping frame 402 are respectively connected to a contact roller 404 for contacting and matching with the outer wall of the pipe to be docked; the transmission connecting member 401 is connected to the mobile push rod assembly 500 slidably arranged on the side wall of the pipe rack structure 100 When the centering and clamping drive 300 controls the resistance roller 404 to resist the outer wall of the pipe to be connected, the transmission connecting piece 401 drives and controls the movable push rod assembly 500 to move in the direction away from the outer wall of the pipe to be connected; when the centering and clamping drive 300 controls the resistance roller 404 to separate from the outer wall of the pipe to be connected, the transmission connecting piece 401 can drive and control the movable push rod assembly 500 to pre-press and fit on the outer wall of the pipe to be connected, and then control the arc-shaped clamping frame 402 to drive the resistance roller 404 to separate from the pipe to be connected.

[0052] When the driving arm 304 drives the arc-shaped clamping frame 402 to move toward the outer wall of the pipe through the transmission connection 401, the abutting roller 404 on the arc-shaped clamping frame 402 abuts against the outer wall of the pipe to be docked, and the abutting roller 404 and the arc-shaped clamping frame 402 can be fixedly connected to ensure the stability of the clamping and prevent the pipe from rotating; the transmission connection 401 is connected to the moving push rod assembly 500 slidably arranged on the side wall of the pipe rack structure 100; when the centering clamping drive 300 controls the abutting roller 404 When the contact roller 404 contacts the outer wall of the pipe to be connected, the transmission connector 401 drives and controls the movable push rod assembly 500 to move away from the outer wall of the pipe to be connected, so as to prevent the movable push rod assembly 500 from contacting the pipe and causing interference; and when the centering and clamping drive 300 controls the contact roller 404 to separate from the outer wall of the pipe to be connected, before the contact roller 404 separates from the outer wall of the pipe, the transmission connector 401 can first drive and control the movable push rod assembly 500 to pre-press and fit against the outer wall of the pipe to be connected, so as to prevent the movable push rod assembly 500 from contacting the pipe and causing interference. The obtained pipeline is supported and fixed by multiple mobile push rod assemblies 500, and then the arc-shaped clamping frame 402 is controlled to drive the resistance roller 404 to separate from the pipeline to be docked, so as to prevent the lack of effective support of the docked pipeline and cause damage to the docking point. The arrangement of this structure allows the present invention to be used without relying on the bracket for supporting the pipeline to be docked. The present invention can be used for docking pipelines and can also be used for supporting pipelines. After docking, when multiple mobile push rod assemblies 500 are in resistance and fit on the side wall of the pipeline, the contact position between the automatic centering clamping device 1 and the pipeline can be changed by moving the automatic centering clamping device 1, so as to facilitate the control of the present invention to move as a whole to the pipeline to be docked later, without the need for overall disassembly, to achieve continuous docking of the pipelines. When the automatic centering clamping device 1 moves to the two pipelines to be docked later, a pipeline bracket can be installed at the already docked pipeline, so as to support the already docked pipeline without affecting the movement of the present invention as a whole on the pipeline, thereby improving the docking efficiency.

[0053] In the present invention, the arc-shaped clamping frame 402 contacts the outer wall of the pipe to be docked through the resistance roller 404, providing a strong clamping force to prevent the pipe from rotating or deviating during the docking process; before the centering clamping drive 300 controls the resistance roller 404 to separate from the outer wall of the pipe, the mobile push rod assembly 500 can be pre-pressed and fitted on the outer wall of the pipe to provide additional support force to ensure that the pipe will not be damaged due to lack of support after docking; through the dual mechanism of clamping and support, the stability and reliability of pipe docking can be effectively guaranteed, and problems caused by insufficient support during the docking process can be avoided; in addition, the present invention has an independent docking function without support dependence. Through the supporting effect of the mobile push rod assembly 500, the present invention can complete the docking of pipes without relying on traditional pipe supports, which reduces the demand for additional equipment during the docking process, simplifies the construction process, and does not need to install the support before docking, which reduces the time for equipment installation and disassembly, reduces the construction cost, and improves the construction efficiency; after completing a docking, the automatic centering clamping device 1 can change the contact position with the pipe through the cooperation of the mobile push rod assembly 500, and move the whole to the rear At the pipes that need to be connected, there is no need to disassemble the equipment, and then a pipe support can be installed on the connected pipes to support the connected pipes without affecting the movement of the equipment; continuous pipe connection is realized, the time of equipment movement and disassembly is reduced, and the connection efficiency and construction flexibility are significantly improved; the transmission connector 401 is not only responsible for driving the arc clamping frame 402 and the resistance roller 404, but also connected with the mobile push rod assembly 500 to achieve dynamic adjustment at different stages; for example, when clamping, the transmission connector 401 controls the mobile push rod assembly 500 to stay away from the outer wall of the pipe to avoid interference; when releasing, the transmission connector 401 pre-controls the mobile push rod assembly 500 to press the pipe to provide support; through precise dynamic adjustment, it is ensured that every link in the pipe connection process can be carried out efficiently and stably, reducing operational errors and human intervention; the number of mobile push rod assemblies 500 is adjustable, which can adapt to pipes of different lengths and diameters and provide uniform support force; the equipment can flexibly respond to pipe connection requirements under different working conditions and is suitable for various complex environments, such as large-diameter pipes, long-distance pipes and pipes of special shapes.

[0054] The transmission connecting member 401 includes: a force transmission slide 405 slidably arranged in the guide sleeve of the arc-shaped clamping frame 402, one end of the force transmission slide 405 is rotatably connected to the driving arm 304, a horizontal card contact shaft 407 is slidably matched in the transmission slide groove 406 of the force transmission slide 405, and the horizontal card contact shaft 407 is fixed to the arc-shaped clamping frame 402 through a connecting block, and a T-block 409 is slidably matched in the side T-shaped slide groove 408 at the other end of the force transmission slide 405, and the T-block 409 is fixed to one end of the support rod 410, and the support rod 410 is inserted into the rectangular horizontal In the hole, the other end of the support rod 410 is fixed with a side seat 412, and a spiral spring 413 fixed between the side seat 412 and the spiral transmission rod 411 is sleeved on the support rod 410; the spiral gear 414 meshing with the spiral transmission rod 411 is fixed to the middle of the wheel axle 415, and the wheel axle 415 is rotated on the inner side of the pipe frame structure 100 through the shaft frame 416; the spiral transmission rod 411 is slidably mounted on two hanging plates 417 on the inner side of the pipe frame structure 100; the two cylindrical gears 418 fixed at both ends of the wheel axle 415 are connected to the movable top rod assembly 500.

[0055] When it is necessary to control the abutment roller 404 to abut against the outer wall of the pipe to be docked, the driving arm 304 drives the force transmission slide 405 to move in the direction away from the driving ring 302, and the force transmission slide 405 slides on the horizontal clamping shaft 407 and slides in the guide sleeve of the arc-shaped clamping frame 402, and keeps moving along the axial direction of the pipe rack structure 100. At this time, the relative position of the abutment roller 404 and the inner wall of the pipe rack structure 100 does not change. With the movement of the force transmission slide 405, the force transmission slide 405 presses the spiral transmission rod 411 to move in the direction away from the driving ring 302, such as Fig.14As shown, the spiral transmission rod 411 meshes with the spiral gear 414 and rotates clockwise, and the spiral gear 414 drives the two cylindrical gears 418 to rotate clockwise through the wheel shaft 415, thereby meshing the transmission to control the movable push rod assembly 500 to slide outward. When the horizontal contact shaft 407 contacts the inner wall of the transmission slide groove 406 close to the end of the driving arm 304, the horizontal height of the bottom of the movable push rod assembly 500 is higher than the horizontal height of the bottom of the friction roller 404. At this time, the friction rollers 404 are pressed against the outer wall of the pipe; when it is necessary to control the friction rollers 404 to separate from the outer wall of the pipe to be connected, before the friction rollers 404 separate from the outer wall of the pipe Before, control the force transmission slide 405 to move in the direction close to the drive ring 302. At this time, the force transmission slide 405 slides on the horizontal card contact shaft 407 through the transmission slide groove 406. The force transmission slide 405 drives the T-block 409 to move in the direction of the drive ring 302 through the side T-shaped slide groove 408. The T-shaped block 409 drives the spiral transmission rod 411 to move in the direction of the drive ring 302 through the cooperation of the support rod 410, the side seat 412 and the spiral spring 413. At this time, the spiral transmission rod 411 engages with the spiral gear 414 to rotate counterclockwise, thereby driving the two cylindrical gears 418 to rotate counterclockwise, and the two cylindrical gears 418 are engaged. The transmission moving push rod assembly 500 moves in the direction of the docking pipe, so that the moving push rod assembly 500 is in contact with the pipe. After the moving push rod assembly 500 contacts the pipe, since the moving push rod assembly 500 cannot continue to move inward, the relative positions of the spiral transmission rod 411 and the spiral gear 414 are fixed, maintaining a stable locking state. As the force transmission slide 405 continues to move, the support rod 410 drives the side seat to compress the spiral spring 413 so that it does not affect the movement of the force transmission slide 405. When the horizontal card contact shaft 407 contacts the inner wall of the transmission slide 406 close to the T-block 409 end, the moving push rod The horizontal height of the bottom of the component 500 is lower than the horizontal height of the bottom of the friction roller 404. At this time, the movable push rod component 500 is pressed against the outer wall of the pipe to be connected, so that the pipe is supported and fixed by multiple movable push rod components 500; as the force transmission slide 405 continues to move, the force transmission slide 405 generates a pulling force on the horizontal clamping contact shaft 407 through the transmission slide groove 406. At this time, the arc-shaped clamping frame 402 can be driven by the horizontal clamping contact shaft 407 to move toward the inner wall of the pipe rack structure 100, and the arc-shaped clamping frame 402 drives the two guide arm rods 403 to slide toward the outside of the pipe rack structure 100, thereby releasing the friction fixation between the friction roller 404 and the outer wall of the pipe.

[0056] The movable push rod assembly 500 includes: two movable rods 501 slidably arranged in the through holes on the side walls of the pipe rack structure 100, the rack teeth on the side faces of the movable rods 501 mesh with the cylindrical gear 418, and the ends of the two movable rods 501 extending into the pipe rack structure 100 are both provided with running wheels 502, and the axes of the running wheels 502 are perpendicular to the axes of the abutting rollers 404, and the ends of the two movable rods 501 extending outside the pipe rack structure 100 are connected through an outer plate 503, and the outer plate 503 and the pipe rack structure 100 are connected through a coil spring 2 504, and under the same compression conditions, the elastic force generated by the coil spring 2 504 is less than that of the coil spring 1 413. When the cylindrical gear 418 rotates, it meshes with the transmission moving rod 501, so that the moving rod 501 slides in the through hole on the side wall of the pipe rack structure 100, so that the two moving rods 501 pass through the running wheels 502 in the pipe rack structure 100 and contact or separate from the docked pipe. When the running wheels 502 abut against the docked pipe, since the axis of the running wheels 502 is perpendicular to the axis of the abutting roller 404, the automatic centering and clamping device 1 can be moved to change its contact position with the pipe, so as to facilitate its movement to the subsequent pipe to be docked.

[0057] The automatic centering and clamping device 1 also includes: a cylinder assembly 600 for driving the pipe rack structure 100 to rotate in the horizontal installation opening, and the cylinder assembly 600 includes: a cylinder body 601 fixed on the load-bearing frame 200, the cylinder body 601 is connected to a movable plate 602 slidably mounted in the cross slideway at the top of the load-bearing frame 200, and a transverse rack installed on the lower surface of the movable plate 602 is meshed and connected with an outer gear ring fixed on the outer wall of the pipe rack structure 100. After the cylinder body 601 is started, it can drive the movable plate 602 to slide in the cross slideway at the top of the load-bearing frame 200, so that the transverse rack on the lower surface of the movable plate 602 meshes with the outer gear ring on the outer wall of the pipe rack structure 100 to rotate, thereby controlling the pipe rack structure 100 to rotate in the horizontal installation opening, and can adjust and control the rotation of the pipeline to meet the bonding or welding requirements after the pipeline is butted.

[0058] The four corners of the stand 5 are respectively connected to a Forma wheel to facilitate the overall movement of the present invention; the rolling wheels of the support platform 2 3 roll in the guide groove on the upper surface of the stand 5 to reduce the friction resistance of the support platform 2 3 during movement and improve the docking stability of the two pipes to be docked.
