Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline installation and construction, and more specifically, to a large-scale pipeline welding adjustment device. Background Art
[0002] During pipeline installation and construction, the butt welding of two pipes is a common task. To ensure the two pipe ends are flush, an adjustment device is typically used to adjust the relative position of the two pipes, enabling rapid butt welding. Traditionally, workers fabricate custom lugs and latches, attaching them to one end of the pipe and adjusting the position by tapping the triangular latch. However, when dealing with very large pipes, the number of butt welds required is enormous. This not only requires time and effort, but also poses safety risks and is unreliable.
[0003] After searching the prior art, the existing patent numbers are: CN214558516U and CN211966517U. The disclosed pipe welding docking devices facilitate the docking between pipe interfaces, are relatively simple to dock, and are convenient for workers to weld. They can replace the manual hammering method in the prior art to achieve the adjustment of large pipe welding. However, the pipe welding docking devices in the above-mentioned patents still have certain restrictions on the diameter of the pipe. For example, a set of tooling can only be used for the docking adjustment of pipes of one diameter, which has limitations in use. In addition, since there are certain requirements for the width of the weld seam of pipe welding, when two pipes are roughly docked, the distance between the end faces of the two pipes cannot be well guaranteed. The pipe welding docking devices in the above-mentioned patents can only adjust the radial position alignment and cannot accurately adjust the weld seam width of the weld seam, which is still relatively inconvenient to use.
[0004] Therefore, it is urgent to design a novel large-scale pipeline welding adjustment device to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a large-scale pipeline welding adjustment device for the above-mentioned deficiencies in the prior art, which can be applied to the adjustment of pipelines with different diameters and can adjust the weld width at the same time, making it more convenient to use.
[0006] The technical solution of the utility model is as follows: a large-scale pipeline welding adjustment device includes multiple adjustment components, each of the adjustment components includes a fixed plate, an adjustment plate and a stainless steel tie, the stainless steel tie is movably inserted into the fixed plates corresponding to the multiple adjustment components, the stainless steel tie is provided with a plurality of evenly arranged tooth grooves along its length direction, one end of the stainless steel tie is provided with a locking mechanism for locking the other end of the stainless steel tie; one end of the adjustment plate is threadedly connected to a counter-thrust bolt, one end of the fixed plate is provided with at least one guide rod, the guide rod is slidably inserted into the other end of the adjustment plate, and an adjustment mechanism for adjusting the relative distance between the fixed plate and the adjustment plate is also provided between the fixed plate and the adjustment plate.
[0007] As a further improvement, the locking mechanism includes a locking shell and a screw. The locking shell is a hollow shell. The locking shell is fixed to one end of the stainless steel cable tie. The screw is located in the locking shell. Both ends of the screw are rotatably connected to the locking shell through a rotating shaft. One of the rotating shafts passes through the locking shell, and the screw is meshed with the tooth groove to form a worm gear transmission mechanism.
[0008] Furthermore, one of the rotating shafts passes through the locking shell and is fixedly connected to a hexagonal socket head.
[0009] Furthermore, the adjustment mechanism includes a screw rod, and support plates are provided on the fixed plate and the adjustment plate. The screw rod is threadedly connected to the corresponding support plate on the fixed plate, and one end of the screw rod movably passes through the corresponding support plate on the adjustment plate and is fixedly connected to the limiting plate.
[0010] Furthermore, the other end of the screw rod passes through the corresponding support plate on the fixed plate and is fixedly connected to the turntable.
[0011] Furthermore, a pressure plate is installed at the end of the counter-thrust bolt through a bearing.
[0012] Furthermore, the bottom of the pressing plate is provided with anti-slip grooves.
[0013] Beneficial effects
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1. The large-scale pipeline welding adjustment device of the present invention has multiple adjustment components that are fastened by adjustable stainless steel cable ties. In actual use, the two butt-jointed pipes are first hoisted with lifting equipment to adjust the rough gap, and then the stainless steel cable tie with multiple adjustment components is wrapped around one of the butt-jointed pipes. The other end of the stainless steel cable tie is passed through the locking mechanism, and the locking mechanism is adjusted to gradually tighten the stainless steel cable tie so that the multiple adjustment components are fixed on the butt-jointed pipe. Then, the counter-jacking bolt is rotated to counter-jack the other butt-jointed pipe radially until the ends of the two butt-jointed pipes are flush. Since the stainless steel cable tie is an adjustable structure, the adjustment device can be suitable for butt-jointed adjustment of pipes with different diameters.
[0016] 2. The large-scale pipeline welding adjustment device of the present invention has a fixed plate and an adjusting plate that are relatively adjustable. During the adjustment process, if the weld distance between the two butt-jointed pipes does not meet the welding requirements, the screw rod can be rotated to drive the adjusting plate to move axially relative to the fixed plate, thereby adjusting the distance between the two butt-jointed pipes to achieve the purpose of adjusting the weld distance. This allows both pipe docking and weld width to be adjusted, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0023] See Figure 1-4The utility model is a large-scale pipeline welding adjustment device, which is characterized in that it includes multiple adjustment components, each adjustment component includes a fixed plate 1, an adjustment plate 2 and a stainless steel tie 3, wherein the stainless steel tie 3 is movably arranged in the fixed plates 1 corresponding to the multiple adjustment components, that is, the fixed plate 1 can slide relative to the stainless steel tie 3, so that the position of each adjustment component can be adjusted so that the multiple adjustment components can be evenly distributed on the periphery of the butt joint 17, and a plurality of evenly arranged tooth grooves 4 are opened on the stainless steel tie 3 along its length direction. A locking mechanism 16 for locking the other end of the stainless steel tie 3 is provided at one end of the stainless steel tie 3, and a counter-top bolt 5 is threadedly connected to one end of the adjustment plate 2 to push the butt joint 17 to move radially. Preferably, the locking mechanism 16 includes a locking shell 7 and a screw 8, wherein the locking shell 7 is a shell with a hollow structure, and the width of the inner cavity of the locking shell 7 is slightly larger than the width of the stainless steel tie 3 to ensure that the stainless steel tie 3 can be inserted into the locking shell 7. The locking shell 7 is fixed to one end of the stainless steel tie 3, and the screw 8 is located in the locking shell 7. Both ends of the screw 8 are rotatably connected to the locking shell 7 through a rotating shaft 9, one of the rotating shafts 9 passes through the locking shell 7, and the screw 8 is meshed with the tooth groove 4 to form a worm gear transmission mechanism. By rotating the screw 8, the stainless steel tie 3 can be tightened or loosened to adjust the diameter of the cavity formed by the stainless steel tie 3, so as to be suitable for welding adjustments of pipelines with different diameters.
[0024] The large-scale pipeline welding adjustment device of the present invention has multiple adjustment components that are fastened by adjustable stainless steel cable ties 3. In actual use, the two butt-jointed pipes 17 are first hoisted with lifting equipment to adjust the rough gap, and then the stainless steel cable tie 3 with multiple adjustment components is wrapped around one of the butt-jointed pipes 17. The other end of the stainless steel cable tie 3 is passed through the locking mechanism 16. The locking mechanism 16 is adjusted to gradually tighten the stainless steel cable tie 3 so that the multiple adjustment components are fixed on the butt-jointed pipe 17. Then, the counter-jacking bolt 5 is rotated to counter-jack the other butt-jointed pipe 17 and move radially until the ends of the two butt-jointed pipes 17 are flush. Since the stainless steel cable tie has an adjustable structure, the adjustment device can be suitable for butt-jointed adjustment of pipes with different diameters.
[0025] Preferably, one of the rotating shafts 9 passes through the locking shell 7 and is fixedly connected to a hexagonal head 10 to facilitate the rotation of the screw 8.
[0026] Preferably, at least one guide rod 6 is provided at one end of the fixed plate 1. The guide rod 6 is slidably inserted into the other end of the adjustment plate 2 to play a guiding role. At the same time, it can also increase the connection strength between the fixed plate 1 and the adjustment plate 2, preventing the adjustment plate 2 from deforming relative to the fixed plate 1 when the reverse-pushing bolt 5 is reversed. An adjustment mechanism for adjusting the relative distance between the fixed plate 1 and the adjustment plate 2 is also provided. Specifically, the adjustment mechanism includes a screw 11, wherein both the fixed plate 1 and the adjustment plate 2 are provided with a support plate 12. The screw 11 is threadedly connected to the corresponding support plate 12 on the fixed plate 1, and one end of the screw 11 movably penetrates the corresponding support plate 12 on the adjustment plate 2 and is fixedly connected to the limit plate 13.
[0027] The large-scale pipeline welding adjustment device of this embodiment has a relatively adjustable structure in which the fixed plate 1 and the adjustment plate 2 are structured. During the adjustment process, if the weld distance between the two butt-jointed pipes 17 does not meet the welding requirements, the screw rod 11 can be rotated to drive the adjustment plate 2 to move axially relative to the fixed plate 1, thereby adjusting the distance between the two butt-jointed pipes 17 to achieve the purpose of adjusting the weld distance. This allows both pipe docking and weld width to be adjusted at the same time, making it more convenient to use.
[0028] Preferably, the other end of the screw rod 11 passes through the corresponding support plate 12 on the fixed plate 1 and is fixedly connected to a turntable 14 to facilitate the rotation of the screw rod 11.
[0029] Preferably, a pressure plate 15 is mounted on the end of the counter-thrust bolt 5 via a bearing. When the counter-thrust bolt 5 is rotated, the pressure plate 15 can remain stationary, so that the pressure plate 15 is axially pressed against the outer wall of the butt joint 17, reducing damage to the butt joint 17. Furthermore, anti-slip grooves are provided on the bottom of the pressure plate 15 to increase the friction between the pressure plate 15 and the butt joint 17, thereby ensuring that the adjustment plate 2 can pull the butt joint 17 to move slightly axially.
[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
