Description

TECHNICAL FIELD

[0001] The utility model relates to an auxiliary device suitable for process pipeline installation belongs to process pipeline installation technical field. BACKGROUND

[0002] Process pipelines are pipeline systems used to transport various fluids (such as gases, liquids, or slurries) in industrial systems. They are designed and constructed to meet specific production process requirements. These pipelines are generally made of various materials, such as metals or other materials capable of withstanding high temperatures, high pressures, and corrosion, to ensure stable operation under various working conditions.

[0003] During the installation of process pipelines, cranes are usually used to hoist the pipelines to the designated position, and the two sections of the pipeline are connected together through bolt connection or welding. During hoisting, manual assistance is required to butt joint the interfaces of the two sections of the pipeline. Due to the heavy weight of the process pipeline, manual assistance for moving the process pipeline is difficult and often inefficient.

[0004] Although some installation auxiliary tools have been designed in the prior art to fix the hoisted pipeline, as the installation height increases, the amplitude of the pipeline shaking with the auxiliary device increases, making it difficult to control the installation precision of the pipeline, resulting in long butt joint time, low installation precision, risk of pipeline falling during installation, and high failure rate of the auxiliary device. Therefore, it is necessary to provide an auxiliary device suitable for process pipeline installation to solve the above technical problems. SUMMARY

[0005] The utility model aims at overcoming the deficiencies in the prior art and providing an auxiliary device suitable for process pipeline installation. The hoisting mechanism is used to transfer the pipeline to be installed at high altitude. After hoisting in place, the first clamping part and the second clamping part are used to quickly and accurately calibrate the interfaces of the pipeline to be installed and the installed pipeline, solving the problems of high risk of pipeline transfer at high altitude and low efficiency of interface installation in the prior art.

[0006] To solve the above technical problems, the utility model is realized by using the following technical scheme:

[0007] An auxiliary device suitable for process pipeline installation includes a hoisting mechanism for hoisting a pipeline to be installed, a frame connected to the hoisting mechanism, and a first clamping part and a second clamping part arranged on the frame. The first clamping part and the second clamping part are respectively used to clamp the installed pipeline side and the pipeline to be installed side at the butt joint.

[0008] The hoisting mechanism is connected with the hoisting machine, and the to-be-installed pipeline is placed in the second clamping part. During construction, the hoisting mechanism and the hoisting machine are connected to drive the to-be-installed pipeline to be hoisted in the air until the to-be-installed pipeline is close to the installed pipeline. As the to-be-installed pipeline rises, its center of gravity also rises, which reduces the stability of the hoisted pipeline and causes the pipeline to shake to a certain extent. The second clamping part limits the to-be-installed pipeline to reduce the shaking amplitude of the pipeline.

[0009] Optionally, the hoisting mechanism comprises a hoisting frame and a plurality of flexible fixing parts arranged along the length direction of the hoisting frame. One end of each flexible fixing part is connected with the hoisting frame, and the other end is tied into a ring shape for sleeving the to-be-installed pipeline.

[0010] In the above scheme, the flexible fixing part is made of high-strength alloy steel or other high-strength materials. One end is connected to the hoisting frame, and the other end is tied into a ring shape. The ring shape after tying is used to sleeve the to-be-installed pipeline. The flexible characteristics of the flexible fixing part can be applied to the hoisting of pipelines of various shapes. The plurality of lifting rings are used to connect the frame or the hoisting machine through steel wire ropes or steel chains to realize the overall hoisting function of the auxiliary device and the to-be-installed pipeline.

[0011] Optionally, a support table is further arranged on the frame, a connecting part is arranged between the first clamping part and the second clamping part, the first clamping part and the second clamping part form a whole through the connecting part, and the first clamping part and the second clamping part are slidably arranged on the support table.

[0012] During construction, the lifting lugs of the frame are flexibly connected with the lifting rings on the hoisting frame through steel wire ropes or chains, so that the first clamping part, the second clamping part and the support table can slide relative to each other with the swinging of the hoisting frame and the to-be-installed pipeline. The lateral impact force during hoisting can be absorbed and buffered, the swinging amplitude of the to-be-installed pipeline is reduced, the hoisting frame and the to-be-installed pipeline are protected from damage, and the failure rate of the auxiliary device is reduced.

[0013] Optionally, the first clamping part and the second clamping part are identical in structure and comprise a guide rail, a driving part arranged on the guide rail, and a clamping plate that moves relative to or away from the guide rail under the action of the driving part. The first clamping part and the second clamping part are synchronously driven.

[0014] In the above scheme, both ends of the guide rail are respectively provided with sliding seats, and the sliding seats are connected with the clamping plates. The driving part comprises a double-headed screw rod arranged in the guide rail and a motor connected with the double-headed screw rod. The motor is connected to the end of the guide rail. The two sliding seats close to the installed pipeline are first sliding seats, and the two sliding seats close to the to-be-installed pipeline are second sliding seats.

[0015] The first clamping part and the second clamping part are respectively connected with the support table through the first guide rail and the second guide rail, and the first guide rail and the second guide rail are arranged in parallel; during the high-altitude transfer of the to-be-installed pipeline, the center of gravity of the to-be-installed pipeline changes, so that the to-be-installed pipeline shakes to a certain extent and transmits an impact force to the second guide rail, and the sliding connection between the second guide rail and the support table can absorb the swing impact force transmitted by the to-be-installed pipeline, so as to reduce the transverse impact force of the to-be-installed pipeline on the clamping part.

[0016] After hoisting in place, the first sliding seat is close to the installed pipeline, the motor is started and power is output to the double-headed screw rod, so that the two first sliding seats move along the double-headed screw rod and the first guide rail towards the installed pipeline, and the first clamping part and the second clamping part clamp the installed pipeline and the to-be-installed pipeline respectively. When the pipelines are connected at high altitude, if the to-be-installed pipeline is offset, the frame is slightly adjusted in the transverse direction by the hoisting machine, so that the first guide rail and the second guide rail slide relative to the support table respectively, the corresponding positions of the first clamping part and the second clamping part are adaptively fine-tuned, the axial center lines of the to-be-installed pipeline and the installed pipeline are consistent, the precision of the pipeline connection is improved, the adjustment period of the pipeline assembly is shortened, and the pipeline installation efficiency is improved and the labor intensity is reduced.

[0017] Optionally, the first clamping part comprises a guide rail, a driving part arranged on the guide rail, and a clamping plate which moves relative to or away from the driving part on the guide rail under the action of the driving part.

[0018] The second clamping part comprises a guide rail and a clamping plate which moves relative to or away from the guide rail.

[0019] The above scheme can simplify the second clamping part, and the synchronous sliding between the first clamping part and the second clamping part can be realized through the connecting part without increasing the driving part.

[0020] Optionally, the connecting part comprises a connecting seat connected between the guide rail of the first clamping part and the guide rail of the second clamping part, and a synchronous rod between the clamping plate of the first clamping part and the clamping plate of the second clamping part.

[0021] The displacement of the first guide rail and the second guide rail is synchronized through the connecting seat, and the displacement of the clamping plates of the first clamping part and the second clamping part is synchronized through the synchronous rod, so that the first clamping part and the second clamping part can be adaptively adjusted to keep the axial relative synchronization during hoisting.

[0022] Optionally, a plurality of balls are arranged on the surface of the clamping plate of the first clamping part facing the installed pipeline.

[0023] The above scheme can avoid the movement of the installed pipeline with the clamping plate of the first clamping part and reduce the friction between the clamping plate and the installed pipeline. During clamping and adjustment, the axial friction force applied by the clamping plate to the installed pipeline is reduced and offset by the ball, the axial movement of the installed pipeline is avoided, the connection performance of the installed pipeline and other pipelines is affected, and the friction in other directions is reduced to avoid damage to the surface of the pipeline.

[0024] Optionally, the clamping plates of the first clamping part and the second clamping part are arc-shaped, used for being attached to the curved surface of the pipeline, and better clamping effect is achieved.

[0025] Optionally, the first reset device and the second reset device are symmetrically arranged on both sides of the connecting seat, one end of the reset device is connected to the connecting seat, and the other end of the reset device is connected to the support table.

[0026] In the above scheme, the reset device is arranged on both sides of the connecting seat through a plurality of guide columns movably inserted into the connecting seat; the first reset device and the second reset device are reset springs sleeved on the guide columns; mounting seats are arranged at both ends of each guide column, and all the mounting seats are mounted on the support table; one end of the reset spring is connected to the connecting seat, and the other end of the reset spring is connected to the mounting seat, used for providing the connecting seat with reset elastic force.

[0027] The first clamping part and the second clamping part clamp the installed pipeline and the to-be-installed pipeline respectively, if the axis of the to-be-installed pipeline deviates, the frame and the support table are moved transversely by the hoisting machine, the first clamping part remains stationary with the installed pipeline, so that the mounting seat moves relative to the connecting seat along with the support table, thereby extruding the reset spring on the guide column to generate elastic force, after the installed pipeline and the to-be-installed pipeline are connected, the clamping part is separated from the installed pipeline and the to-be-installed pipeline, so that the clamping plate and the connecting seat are not limited by the installed pipeline, the elastic force stored in the reset spring is released to the connecting seat, so that the two guide rails are reset to the original position of the support table.

[0028] Advantages: Compared with the prior art, the utility model has the following advantages:

[0029] 1. The to-be-installed pipeline is moved in the air by the lifting mechanism, and the interfaces of the to-be-installed pipeline and the installed pipeline are quickly and accurately calibrated by the first clamping part and the second clamping part after being lifted into position, so that the risk of pipeline high-altitude transfer is better reduced and the installation efficiency of the interfaces between the pipelines is improved compared with the auxiliary device in the prior art.

[0030] 2. During construction, the sliding connection between the first and second clamping parts and the support platform enables the clamping parts to adaptively adjust the docking position between the pipe to be installed and the already installed pipe, shortening the adjustment cycle of pipe assembly and reducing labor intensity.

[0031] 3. The reset device transmits elastic force to the support platform through the connecting seat, so that the first clamping part and the second clamping part can be quickly reset to the original position of the support platform, in preparation for the next pipe connection. At the same time, during the movement of the pipe to be installed, the reset spring further absorbs and buffers the lateral impact force during the hoisting process, so that the swing amplitude of the pipe to be installed is smaller, avoiding the risk of falling and reducing the failure rate of the auxiliary device.

[0032] 4. This device can automatically complete most of the alignment and clamping work. Workers only need to perform simple operations and supervision, which greatly reduces the physical labor of workers and reduces the safety risks in the operation process.

[0033] 5. The motor-driven double-ended screw and slide assembly automatically adjust the position of the first clamping plate, ensuring uniform clamping force and docking accuracy, thereby improving the overall installation accuracy and connection reliability.

[0034] 6. The ball bearing design embedded in the inner wall of the first clamping plate reduces the axial friction between the first clamping plate and the installed pipe, thereby reducing the impact on the performance of the installed pipe and the risk of damage to the pipe surface.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0040] The embodiment provides an auxiliary device suitable for process pipeline installation, which comprises a lifting mechanism Figure 1 The lifting mechanism is connected with a frame 1, and the frame 1 is provided with oppositely distributed first clamping parts and second clamping parts; the first clamping parts and the second clamping parts are respectively used for clamping the installed pipeline side and the to-be-installed pipeline side at the butt joint.

[0042] During construction, the to-be-installed pipeline can be lifted by the connection of the lifting mechanism and the lifting machine until the to-be-installed pipeline is close to the installed pipeline and the auxiliary device is pulled to move horizontally, along with the lifting of the to-be-installed pipeline, the center of gravity of the to-be-installed pipeline is also lifted, so that the stability of the to-be-installed pipeline is reduced, and the to-be-installed pipeline shakes in a certain amplitude; the second clamping parts limit the to-be-installed pipeline, so that the shaking amplitude of the to-be-installed pipeline is reduced.

[0043] Optionally, as shown in Figure 1 The two flexible fixing parts 18 are arranged along the axial direction of the lifting frame 2, one end of each flexible fixing part 18 is connected to the lifting frame 2, and the other end is tied into a ring shape and used for sleeving the to-be-installed pipeline.

[0044] The flexible fixing part 18 can be made of high-strength alloy steel or other high-strength materials, one end of the flexible fixing part 18 is connected to the lifting frame 2, and the other end is tied into a ring shape, and the ring shape after being tied is used for sleeving the to-be-installed pipeline; by virtue of the flexible characteristics of the flexible fixing part 18, the flexible fixing part 18 can be applied to the hoisting of pipelines with various shapes. The plurality of lifting rings are used for being connected to the frame 1 or the lifting machine through steel wires or steel chains, so as to realize the overall hoisting function of the auxiliary device and the to-be-installed pipeline.

[0045] Optionally, as shown in Figure 2The frame 1 comprises a support table 3 and a plurality of lifting lugs, the support table 3 is installed at the bottom of the frame 1 and connected with the first clamping part and the second clamping part, the connecting part is installed between the first clamping part and the second clamping part, the first clamping part and the second clamping part form a whole through the connecting part and are slidingly arranged on the support table; a plurality of lifting lugs are installed on the frame 1, used for being fixed with the flexible connecting piece and connected with the lifting frame 2 through the flexible connecting piece; during construction, the lifting lugs of the frame 1 are flexibly connected with the lifting rings on the lifting frame 2 through steel wires or chains, so that the first clamping part, the second clamping part and the support table 3 can relatively slide with the swinging of the lifting frame 2 and the pipeline to be installed, the transverse impact force in the hoisting process can be absorbed and buffered, the swinging amplitude of the pipeline to be installed is reduced, the lifting frame 2 and the pipeline to be installed are protected from being damaged, and the failure rate of the auxiliary device is reduced.

[0046] Optionally, the connecting part comprises a connecting seat 13 connected between the guide rails of the first clamping part and the second clamping part and a synchronous rod 17 between the clamping plates of the first clamping part and the second clamping part.

[0047] Optionally, the first clamping part comprises a guide rail, a driving part arranged on the guide rail and a clamping plate relatively or oppositely moving on the guide rail under the action of the driving part; the second clamping part comprises a guide rail and a clamping plate relatively or oppositely moving on the guide rail. The guide rails of the first clamping part and the second clamping part comprise a first guide rail 4 and a second guide rail 10; a sliding groove adapted to the first guide rail 4 and the second guide rail 10 is formed on the support table 3, and the bottom of the first guide rail 4 and the second guide rail 10 is provided with a sliding block, and the first guide rail 4 and the second guide rail 10 are slidingly installed on the support table 3 through the sliding block.

[0048] The two ends of the first guide rail 4 and the second guide rail 10 are respectively provided with sliding seats, including two first sliding seats 5 and two second sliding seats 11; the two first sliding seats 5 are respectively clamped at the two ends of the first guide rail 4; the two second sliding seats 11 are respectively clamped at the two ends of the second guide rail 10; a clamping plate is connected to each sliding seat; the first guide rail 4 and the second guide rail 10 are parallel to each other; the driving part comprises a double-headed screw 7 installed in the first guide rail and a motor 6 connected with the double-headed screw 7, and the motor 6 is connected to the end of the first guide rail 4. The first guide rail 4 and the second guide rail 10 realize displacement synchronization through the connecting seat 13, and the clamping plates of the first clamping part and the second clamping part realize displacement synchronization through the synchronous rod 17, so that the first clamping part and the second clamping part can be adaptively adjusted to keep the axial relative synchronization during the hoisting process.

[0049] During the high-altitude transport of the pipeline to be installed, the change in its center of gravity causes a certain degree of swaying, transmitting impact force to the second guide rail 10. The sliding connection between the second guide rail 10 and the support platform 3 absorbs the swaying impact force transmitted by the pipeline, thereby reducing the lateral impact force of the pipeline on the clamping part. After hoisting into place, the first sliding block 5 approaches the installed pipeline, the motor 6 is started and outputs power to the double-ended screw 7, so that the two first sliding blocks 5 move along the double-ended screw 7 and the first guide rail 4 toward the installed pipeline, so that the first clamping part and the second clamping part clamp the installed pipeline and the pipeline to be installed respectively. When connecting pipelines at high altitude, if the pipeline to be installed is offset, the crane drives the frame 1 to make a slight lateral adjustment, so that the first guide rail 4 and the second guide rail 10 slide relative to the support platform 3, and adaptively fine-tune the corresponding positions of the first clamping part and the second clamping part, so that the axis of the pipeline to be installed is aligned with that of the installed pipeline, improving the accuracy of pipeline connection, shortening the adjustment cycle of pipeline assembly, improving pipeline installation efficiency and reducing labor intensity.

[0050] Optionally, the clamping plate includes two first clamping plates 8 and two second clamping plates 12; the two first clamping plates 8 are respectively connected to two first sliding blocks 5, and the two second clamping plates 12 are respectively connected to two second sliding blocks 11; the two second clamping plates 12 are close to the flexible fixing part 18 and are used to clamp the pipe to be installed; a synchronizing rod 17 is connected between the first clamping plates 8 and the second clamping plates 12 to make the second clamping plates 12 move synchronously with the first clamping plates 8. The pipes to be connected usually have the same diameter. When the first clamping plate 8 clamps the installed pipe, the second clamping plate 12 also clamps the pipe to be installed.

[0051] The first clamping plate 8 moves relative to the installed pipe via the first sliding block 5 until it clamps both sides of the installed pipe. During the movement of the two first clamping plates 8, the two second clamping plates 12 move relative to each other via the synchronizing rod 17, so that the two second clamping plates 12 clamp the pipe to be installed.

[0052] Optionally, the two first clamping plates 8 are used to clamp the installed pipe. A plurality of ball bearings 9 are provided on the opposing surfaces of the two first clamping plates 8 to prevent the installed pipe from moving with the first clamping plates 8 and to reduce the friction between the first clamping plates 8 and the installed pipe. During clamping and adjustment, the ball bearings 9 reduce and counteract the axial friction force applied by the first clamping plates 8 to the installed pipe, preventing axial movement of the installed pipe and affecting its connection performance with other pipes. Simultaneously, they reduce friction in other directions to avoid damage to the pipe surface.

[0053] Optionally, both the first clamping plate 8 and the second clamping plate 12 are arc-shaped to fit against the curved surface of the pipe, thus achieving a better clamping effect.

[0054] Optionally, a first reset device and a second reset device are symmetrically distributed on both sides of the connecting seat 13. One end of the reset device is connected to the connecting seat 13. The reset devices are arranged on both sides of the connecting seat 13 through multiple guide posts 15 that are movably inserted into the connecting seat. The first reset device and the second reset device are both reset springs 16 fitted on the guide posts 15. Each guide post 15 has a mounting seat 14 at both ends. All mounting seats 14 are mounted on the support platform 3. One end of the reset spring 16 is connected to the connecting seat 13 and the other end is connected to the mounting seat 14 to provide reset spring force for the connecting seat 13.

[0055] The number of guide posts 15 is not limited. In this embodiment, two guide posts 15 are used. The two guide posts 15 are movably inserted into the connecting seat 13. Two return springs 16 are fitted on each guide post 15 and are symmetrically arranged on both sides of the connecting seat 13. Two mounting seats 14 are connected to both ends of each guide post 15. All mounting seats 14 are fixedly installed on the support platform 3.

[0056] Each return spring 16 has one end connected to the connecting seat 13 and the other end connected to the mounting seat 14, providing a return force to the connecting seat 13. When the first clamping part and the second clamping part clamp the installed pipe and the pipe to be installed, respectively, if the axis of the pipe to be installed deviates, the frame 1 and the support platform 3 are moved laterally by the hoist. The first clamping part, the connecting seat 13, and the second clamping part remain stationary with the installed pipe. Thus, the mounting seat 14 moves relative to the connecting seat 13 with the support platform 3, thereby squeezing the return spring 16 on the guide column 15. After the installed pipe and the pipe to be installed are connected, the clamping part disengages from both the installed pipe and the pipe to be installed, so that the first clamping plate 8 is no longer restricted by the installed pipe. The spring force stored in the return spring 16 is released to the connecting seat 13, causing the two guide rails to return to the original position of the support platform 3. In addition, during the movement of the pipe to be installed, the return spring 16 further absorbs and buffers the lateral impact force during the hoisting process, making the swing amplitude of the pipe to be installed smaller.

[0057] Working principle:

[0058] During construction, the lifting frame 2 is first lifted by a crane, and then the pipe to be installed is fixed in two flexible fixing parts 18, with one end of the pipe extending between the two second clamping plates 12. Then, the auxiliary device is lifted by the crane, and the lifting frame 2 is moved so that the two first clamping plates 8 are moved to both sides of the installed pipe. Then, the motor 6 is started. When the motor 6 rotates, it drives the double-headed screw 7 to rotate, thereby driving the two first sliding blocks 5 to move closer to each other, so that the two first clamping plates 8 move closer to each other, thus clamping the two first clamping plates 8 on both sides of the installed pipe. At the same time, when the first clamping plates 8 move, the second clamping plates 12 move synchronously through the synchronizing rod 17, so that the two second clamping plates 12 clamp the two sides of the pipe to be installed, thus clamping both pipes.

[0059] If the installed pipe and the pipe to be installed are not coaxially aligned, the first clamping part remains stationary because the first clamping plate 8 is clamped to the installed pipe. At this time, the frame 1 and the support platform 3 can be moved by the hoist, so that the first guide rail 4 and the second guide rail 10 slide relative to the support platform 3 respectively. During this process, the second clamping plate 12 drives the pipe to be installed inside it to automatically and adaptively approach the axis of the installed pipe. The inner wall of the first clamping plate 8 is connected with ball bearings 9. At this time, the installed pipe will not move. Finally, the interfaces of the two pipes are quickly aligned coaxially, the accuracy between the interfaces of the two pipes is finely adjusted, and finally the two pipes can be connected together by bolts or welding.

[0060] After the installed pipe is connected to the pipe to be installed, the clamping part is disengaged from both the installed pipe and the pipe to be installed, so that the first clamping plate 8 is no longer restricted by the installed pipe. The elastic force stored in the return spring 16 is released to the connecting seat 13, so that the two guide rails are reset to the original position of the support platform 3, in preparation for the next pipe connection. Example

[0061] This embodiment provides an auxiliary device suitable for process piping installation, including a hoisting mechanism. A frame 1 is connected to the hoisting mechanism, and a first clamping part and a second clamping part are provided on the frame 1, which are arranged opposite to each other. The first clamping part and the second clamping part are used to clamp the installed pipe side and the pipe side to be installed at the joint, respectively. The hoisting mechanism is equipped with multiple flexible fixing parts, a lifting frame, and multiple lifting rings, and the multiple lifting rings are connected to the lifting frame. The frame is connected to the lifting frame, and the lifting frame is connected to a hoist. The pipe to be installed is placed in the multiple flexible fixing parts and the second clamping part. The first clamping part and the second clamping part clamp the pipe to be installed and the installed pipe, respectively, to align the interfaces of the pipe to be installed and the installed pipe.

[0062] Optionally, the first clamping part is designed the same as in Embodiment 1. The structures of the first clamping part and the second clamping part are identical, both including a guide rail, a drive unit disposed on the guide rail, and clamping plates that move relative to or away from each other on the guide rail under the action of the drive unit. The first clamping part and the second clamping part are driven synchronously. The drive unit is a combination design of a motor and a double-ended screw, or other linear module designs can be used.

[0063] Optionally, the multiple flexible fixing parts are arranged along the axial direction of the lifting frame, and one end of each flexible fixing part is connected to the lifting frame, while the other end is connected to an annular clamp or a pipe sleeve adapted to the pipe to be installed, which is used to fit onto the surface of the pipe to be installed to achieve the purpose of lifting the pipe to be installed.

[0064] Optionally, the clamping plates in the clamping part are not limited to other shapes. When the pipe is of other shapes, the first and second clamping plates can be adapted to be replaced with shapes that match them, such as straight plates and L-shaped plates. Other devices in this embodiment are the same as those in Embodiment 1.

[0065] This invention utilizes a hoisting mechanism to move the pipeline to be installed at high altitudes. After hoisting and positioning, the first and second clamping parts quickly and accurately calibrate the interfaces between the pipeline to be installed and the already installed pipeline. Compared to auxiliary devices in existing technologies, this significantly reduces the risks associated with high-altitude pipeline movement and improves the installation efficiency of pipeline interfaces. During construction, the sliding connection between the first and second clamping parts and the frame allows the clamping parts to adaptively adjust the docking position between the pipeline to be installed and the already installed pipeline, shortening the adjustment cycle during pipeline assembly, improving installation efficiency, and reducing labor intensity. The reset device transmits elastic force to the support platform through the connecting seat, enabling the guide rails of the first and second clamping parts to quickly reset the support platform to its original position, preparing for the next pipeline docking. Simultaneously, the reset spring further absorbs and buffers the lateral impact force during hoisting, minimizing the swaying amplitude of the pipeline to be installed. Using this device, most alignment and clamping work can be completed automatically, requiring only simple operation and supervision from workers, greatly reducing physical labor and safety risks during operation. The motor-driven double-ended screw and slide assembly automatically adjust the position of the first clamping plate, ensuring uniform clamping force and docking accuracy, thereby improving the overall installation accuracy and connection reliability. The ball bearing design embedded in the inner wall of the first clamping plate reduces the axial friction between the first clamping plate and the installed pipe, reducing the impact on the performance of the installed pipe and the risk of damage to the pipe surface.
