Description

Technical Field

[0001] A gas pipeline hoisting and construction device is used for gas pipeline hoisting and construction, belonging to the field of gas pipeline construction technology. Background Technology

[0002] The specific steps for gas pipeline hoisting construction in existing technology are as follows: The crane is driven to the designated hoisting position. The supervisor directs the crane operator to move the hook to the center of the top of the pipeline to be hoisted, adjusts the centering, and stops operating the crane. After the crane is in position, the rigging is attached to both ends of the pipeline or two pairs of arc-shaped clamps are used to hold the pipeline. A trial lift is performed by lifting 100mm. The crane operator should fasten the guy ropes. The crane operator holds the guy ropes, and then the supervisor directs the crane operator to slowly raise the hook. After the pipeline is 0.2m above the ground, the lifting is stopped, and the site supervisor begins to check for any abnormalities in the wire rope, U-ring, and guy rope connections. After the inspection is completed, the signal is relayed back to the supervisor, who then directs the crane operator to continue raising the hook and slowly rotate the boom to lift the pipeline off the ground. The crane operator slowly rotated the boom to lift the pipeline to a position 0.5m above the installation location and stopped the crane. The lifting team stabilized the wind ropes, and the commander directed the crane to slowly lower the pipeline to the installation location to complete the gas pipeline installation.

[0003] In existing technologies, when using arc-shaped clamps to hold pipes, considering that different diameter pipes are usually needed to be clamped and lifted during construction, the installation position or arc size of the arc-shaped clamps must meet the above requirements. However, even when the ability to clamp pipes of different diameters is achieved, existing gas pipeline lifting and construction devices have the following technical problems: When using curved clamps to hold pipes, it is difficult to control the clamping distance, which can easily lead to problems such as insecure clamping or excessive clamping, resulting in damage to the pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a gas pipeline hoisting and construction device to solve the problem that when using arc-shaped clamps to hold pipelines, it is not easy to control the clamping distance, which can easily lead to insecure clamping or excessive clamping, resulting in damage to the pipeline.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A gas pipeline hoisting and construction device includes an installation plate with hanging holes, a clamping structure on the installation plate for clamping the pipeline, the clamping structure including a bidirectional threaded structure and two arc-shaped clamping parts on the bidirectional threaded structure, and a limiting structure on the installation plate for limiting and reminding the two arc-shaped clamping parts to move.

[0006] Furthermore, the bidirectional threaded structure includes two mounting blocks A disposed opposite to each other on the bottom surface of the mounting plate, a bidirectional threaded rod A rotatably disposed on the mounting blocks A, and a rotary motor disposed on the mounting blocks A and connected to one end of the bidirectional threaded rod A; The arc-shaped clamping component includes a vertical rod threaded onto a bidirectional threaded rod A and subject to rotational limitation by a mounting plate, multiple horizontal rods mounted on the vertical rod, and an arc-shaped clamping plate mounted on the horizontal rods.

[0007] Furthermore, the limiting structure includes a T-shaped limiting slide groove on the mounting plate, mounting blocks B at both ends of the T-shaped limiting slide groove, a bidirectional threaded rod B rotatably mounted on the mounting block B, two I-shaped sliders slidably mounted in the T-shaped limiting slide groove and threadedly engaged with the bidirectional threaded rod B, and a limiting rod movably mounted on the I-shaped sliders to provide a limiting reminder for the vertical rod.

[0008] Furthermore, an mounting block C is disposed opposite to the I-shaped slider, a rotating shaft is fixedly disposed on the mounting block C, a limiting rod is rotatably disposed on the rotating shaft, and a torsion spring sleeved on the rotating shaft is disposed between the limiting rod and the mounting block C.

[0009] Furthermore, the limiting rod is equipped with a flexible sensor that receives a feedback signal from the vertical rod pressing on it.

[0010] Furthermore, the mounting plate is also provided with a scale plate, a groove is provided on the scale plate, and a scale pointing block is provided on the I-shaped slider to cooperate with the sliding groove.

[0011] Furthermore, the scale pointing block is a wedge block, with the thin end of the wedge block located on the side of the scale plate where the scale is set.

[0012] Furthermore, the crossbar is provided with a through hole corresponding to the vertical bar, and the arc-shaped clamp is provided with a threaded rod that passes through the through hole. The threaded rod is provided with a nut that fixes the arc-shaped clamp to the crossbar and the vertical bar.

[0013] Furthermore, a rubber pad is provided on the curved clamping plate on the side that holds the pipe.

[0014] Furthermore, a handle for rotating the bidirectional threaded rod B is provided on either side of the bidirectional threaded rod B.

[0015] Compared with the prior art, the advantages of this utility model are: I. This utility model sets a limiting structure on the mounting plate. When the two arc-shaped clamping parts are used to adjust the distance between the two arc-shaped clamping parts during the hoisting construction of the gas pipeline by setting a limiting structure in the clamping structure, the limiting structure can limit and remind the two arc-shaped clamping parts to approach each other, thereby realizing the control of the clamping distance and effectively avoiding the problem of insecure clamping or excessive clamping, which could damage the pipeline. II. The bidirectional threaded structure in this utility model uses a rotary motor to rotate the bidirectional threaded rod A, which in turn causes the arc-shaped clamping plates in the two arc-shaped clamping parts to move closer or further apart, thereby enabling the rapid clamping or release of the gas pipeline. Third, the limiting structure in this utility model adjusts the rotation of the bidirectional threaded rod B to adjust the two I-shaped sliders on it to slide back and forth on the T-shaped limiting slide groove to move closer or further apart, thereby providing a distance limit reminder for the two arc-shaped clamping parts, which can effectively avoid the problem of inaccurate clamping distance control, which can easily cause the clamping to be insecure or too tight. IV. This utility model has a rotating shaft fixedly installed on the I-shaped slider, and a limiting rod rotatably installed on the rotating shaft. The limiting rod is kept perpendicular to the side of the I-shaped slider by a torsion spring in its initial state. When the two arc-shaped clamping parts approach each other and come into contact with the limiting rod, the torsion spring is stressed and the limiting rod will rotate along the rotating shaft. When the limiting rod starts to rotate or comes into contact with the limiting rod, it not only provides a limit reminder for the two arc-shaped clamping parts to move into place, but also avoids the situation where the limiting rod is fixed on the I-shaped slider and is easily broken by force. V. This utility model is equipped with a flexible sensor on the limiting rod. When the flexible sensor is pressed by the vertical rod, it conducts a feedback signal, which can quickly shut down the rotating motor, so as to more accurately control the two arc-shaped clamps to hold the gas pipeline. VI. This utility model sets a scale plate on the mounting plate and a sliding groove on it, and sets a scale pointing block on the I-shaped slider to cooperate with the sliding groove. This makes it easy to adjust the limiting distance between the two limiting rods in advance according to the pipes of different diameters that need to be clamped, so that the flexible sensor on the limiting rod can provide a precise clamping reminder when the pipe is clamped. VII. The limiting scale pointing block of this utility model is a wedge block. The thin end of the wedge block is located on the side of the scale plate where the scale is set. The purpose is to make it easy to accurately correspond to the scale on the scale plate, so as to achieve precise spacing limit adjustment. 8. In this utility model, the arc-shaped clamping plate is fixed to the horizontal and vertical bars by passing through the through holes on the horizontal and vertical bars with threaded rods and cooperating with nuts, which facilitates replacement when damaged; 9. This utility model has a rubber pad on the arc-shaped clamping plate to facilitate clamping and protecting the pipe; 10. The present invention provides a handle on the bidirectional threaded rod B to facilitate rotational adjustment of the bidirectional threaded rod B. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Example 1 To address the problem that existing technologies using curved clamps to hold pipes suffer from difficulty in controlling the clamping distance, leading to either insecure clamping or excessive clamping and damage to the pipe. For example... Figure 1-8 As shown, a gas pipeline hoisting and installation device is provided, including an installation plate 2 with hanging holes 1, a clamping structure 3 on the installation plate 2 for clamping the pipeline, the clamping structure 3 including a bidirectional threaded structure 4 and two arc-shaped clamping parts 5 disposed on the bidirectional threaded structure 4, and a limiting structure 6 on the installation plate 2 for limiting the two arc-shaped clamping parts 5. When clamping a pipeline, at least the following are included: Figure 1The two structures shown.

[0026] In practice, the bidirectional threaded structure 4 is first rotated to move the two arc-shaped clamping parts in opposite directions to ensure that the gas pipeline is placed between the two arc-shaped clamping structures 3. Then, the bidirectional threaded structure 4 is rotated to move the two arc-shaped clamping parts closer together. When they come into contact with the limiting structure 3, the limiting structure 6 acts as a limiting reminder. At this point, the bidirectional threaded structure needs to be stopped rotating to ensure that the two arc-shaped clamping parts firmly clamp the gas pipeline. Then, the hoisting construction is carried out by cooperating with the hoisting hole using a lifting rope, which can also avoid damaging the gas pipeline. In this embodiment, by setting a limiting structure on the mounting plate, when the two arc-shaped clamping parts are used to adjust the distance between them during hoisting construction, the limiting structure can limit the distance between the two arc-shaped clamping parts, thereby achieving control of the clamping distance and effectively avoiding problems such as insecure clamping or excessive clamping, which could damage the pipeline.

[0027] Example 2 Based on Embodiment 1, the bidirectional threaded structure 4 includes two mounting blocks A7 disposed opposite to each other on the bottom surface of the mounting plate 2, a bidirectional threaded rod A8 rotatably disposed on the mounting block A7, and a rotary motor 9 disposed on the mounting block A7 and connected to one end of the bidirectional threaded rod A8; the arc-shaped clamping member 5 includes a vertical rod 10 threaded on the bidirectional threaded rod A8 and rotated by the mounting plate, multiple horizontal rods 11 disposed on the vertical rod 10, and arc-shaped clamping plates 12 disposed on the horizontal rods 11. The bidirectional threaded structure uses the rotation of the rotary motor to drive the bidirectional threaded rod A8 to rotate, thereby causing the arc-shaped clamping plates in the two arc-shaped clamping members to move closer or further apart, thus realizing the rapid clamping or release of the gas pipeline.

[0028] The limiting structure 6 includes a T-shaped limiting groove 13 on the mounting plate 2, mounting blocks B14 at both ends of the T-shaped limiting groove 13, a bidirectional threaded rod B15 rotatably mounted on the mounting block B14, and two I-shaped sliders 16 slidably mounted in the T-shaped limiting groove 13 and threadedly engaged with the bidirectional threaded rod B15. A limiting rod 17 is movably mounted on the I-shaped sliders 16 to provide a limiting reminder for the vertical rod 10. The limiting structure adjusts the rotation of the bidirectional threaded rod B to move the two I-shaped sliders back and forth on the T-shaped limiting groove, bringing them closer or further apart, thus providing a limiting reminder for the proximity of the two arc-shaped clamping parts. This effectively avoids problems such as inaccurate clamping distance control, which can easily lead to insecure clamping or excessive clamping.

[0029] In practice, the diameter of the gas pipeline is first adjusted by adjusting the bidirectional threaded rod B15 to adjust the two I-shaped sliders 16 on it. Under the restriction of the T-shaped limiting groove 13, the two I-shaped sliders 16 move along the bidirectional threaded rod B15 and slide along the T-shaped limiting groove 13 to adjust their spacing. After the two I-shaped sliders 16 are adjusted to the correct position, the limiting rod on them is in the limit reminder position. The reverse rotation of the rotary motor 9 drives the bidirectional threaded rod A8 to rotate, which drives the two arc-shaped clamps 12 to move in opposite directions to ensure that the gas pipeline is placed between the two arc-shaped clamps 12. After the gas pipeline is placed between the arc-shaped clamps 12, the forward rotation of the rotary motor 9 drives the bidirectional threaded rod A8 to rotate, which drives the two arc-shaped clamps 12 to move closer. When they come into contact with the limiting rod 17, the limiting structure 6 plays the role of limiting reminder.

[0030] Example 3 Based on Embodiment 2, an mounting block C18 is disposed opposite to the I-shaped slider 16, and a rotating shaft 19 is fixedly disposed on the mounting block C18. A limiting rod 17 is rotatably disposed on the rotating shaft 19, and a torsion spring 20 sleeved on the rotating shaft 19 is disposed between the limiting rod 17 and the mounting block C18. A rotating shaft is fixedly disposed on the I-shaped slider, and the limiting rod is rotatably disposed on the rotating shaft. The torsion spring keeps the limiting rod perpendicular to the side of the I-shaped slider in its initial state. When the two arc-shaped clamping parts approach each other and their vertical rods contact the limiting rod, the torsion spring is stressed, and the limiting rod will rotate along the rotating shaft. When the limiting rod starts to rotate or contacts the limiting rod, it not only provides a limit reminder for the two arc-shaped clamping parts to move into place, but also avoids the situation where the limiting rod is easily broken due to stress when it is fixed on the I-shaped slider. Conversely, when the limiting rod is not stressed, the torsion spring will drive the limiting rod to reset, which is conducive to the hoisting construction of the next gas pipeline.

[0031] Example 3 Based on Embodiment 2, a flexible sensor 21 (with a transmitter) is provided on the limiting rod 17 to receive a feedback signal when pressed by the vertical rod 10. The restoring force of the torsion spring is greater than the force that enables the flexible sensor to conduct under pressure. By providing a flexible sensor on the limiting rod, a feedback signal is activated when the flexible sensor is pressed by the vertical rod, which can quickly shut down the rotary motor and more precisely control the two arc-shaped clamps to hold the gas pipeline.

[0032] Example 4 Based on embodiment 3, the mounting plate 2 is further provided with a scale plate 22, and a sliding groove 23 is provided on the scale plate 22. The I-shaped slider 16 is provided with a scale pointing block 24 that slides and cooperates with the sliding groove 23. By providing a scale plate and a sliding groove on the mounting plate, and providing a scale pointing block that slides and cooperates with the sliding groove on the I-shaped slider, it is convenient to adjust the limiting distance between the two limiting rods in advance according to the pipes of different diameters to be clamped. This allows the flexible sensor on the limiting rod to provide precise clamping positioning reminders when clamping the pipe.

[0033] Example 5 Based on Embodiment 4, the scale pointing block 24 is a wedge block, with the thin end of the wedge block located on the side of the scale plate 22 where the scale is provided. This is to facilitate precise alignment with the scale on the scale plate, thereby enabling precise spacing limit adjustment. Of course, other structures may be used in practice.

[0034] Example 6 Based on embodiment 5, the crossbar 11 is provided with a through hole 25 corresponding to the vertical bar 10, and the arc-shaped clamping plate 12 is provided with a threaded rod 26 passing through the through hole 25. A nut 27 is provided on the threaded rod 26 to fix the arc-shaped clamping plate 12 to the crossbar 11 and the vertical bar 10. The arc-shaped clamping plate is fixed to the crossbar and the vertical bar by the threaded rod passing through the through hole on the crossbar and the vertical bar and cooperating with the nut, which facilitates replacement if damaged.

[0035] Example 7 Based on Example 6, a rubber pad 28 is provided on the arc-shaped clamping plate 12 on one side of the pipe to facilitate clamping and protecting the pipe.

[0036] Example 8 Based on Embodiment 7, a handle 29 for rotating the bidirectional threaded rod B15 is provided on either side of the bidirectional threaded rod B15 to facilitate rotational adjustment of the bidirectional threaded rod B.
