Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, and in particular to a welding and fitting tool for long-distance pipelines. Background Technology

[0002] Pipe welding refers to a method of connecting pipes using welding technology. Pipe welding typically includes various welding methods such as manual electric arc welding, submerged arc welding, argon arc welding, and gas welding. Different pipe materials and pipe thicknesses require different welding methods.

[0003] In the prior art, such as the Chinese patent publication number CN220993346U, a welding and alignment tool for long-distance pipelines is disclosed. This tool includes a fixed frame, with a fixed plate fixedly connected to the top of the fixed frame. A transmission mechanism is installed inside the fixed plate, comprising a motor, a threaded rod, a threaded sleeve, a support plate, a fixing clamp, and an anti-slip pad. One side of the motor is fixedly connected to the inner wall of the fixed plate, and the output end of the motor is fixedly connected to the threaded rod. The welding and alignment tool for long-distance pipelines provided by this utility model solves the problem that existing tools only support and lift the pipelines, requiring the two pipelines to be pulled to opposite sides to be in a suitable welding position. This pulling process is time-consuming, labor-intensive, inefficient, and impractical.

[0004] In actual production and use, this type of long-distance pipeline welding alignment tool only supports and lifts the pipelines. It also requires pulling the two pipelines to the opposite side. Before welding the two pipelines, they need to be aligned to ensure that they can be welded together properly. This type of long-distance pipeline welding alignment tool does not have an alignment fixing device, which may cause the two pipelines to loosen after alignment, reducing welding efficiency and resulting in poor performance of this device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a welding and fitting tool for long-distance pipelines, which has a good fixing effect when welding and fitting pipeline joints.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a welding and mating tool for long-distance pipelines, comprising a semi-circular pipe clamp, a rotating shaft provided on the outside of the semi-circular pipe clamp, a first base plate fixedly connected to the outside of the semi-circular pipe clamp, a housing fixedly connected to the outside of the first base plate, a hydraulic press fixedly connected inside the housing, a limit hole opened inside the base plate, a first locking arc plate provided on the outside of the first base plate, the output end of the hydraulic press passing through the limit hole and fixedly connected to the first locking arc plate, a first jaw opened inside the semi-circular pipe clamp, a second jaw opened inside the semi-circular pipe clamp, a round shaft rotatably connected inside the first jaw, a locking pin fixedly connected to the outside of the round shaft, a rotating handle provided on the outside of the semi-circular pipe clamp, a second base plate fixedly connected to the outside of the semi-circular pipe clamp, a second locking arc plate fixedly connected to the upper surface of the second base plate, and a second semi-circular pipe clamp rotatably connected to the outside of the rotating shaft.

[0007] By adopting the above technical solution, after the worker opens and places the two pipes inside the semi-circular pipe clamp and the second semi-circular pipe clamp, the two pipes are placed on the upper surface of the second locking arc plate. The semi-circular pipe clamp and the second semi-circular pipe clamp are closed by rotating the shaft. The clamping pin is moved by the round shaft and locked inside the second jaw. Then, the two pipes are slowly joined together by hand. After the joint is completed, the hydraulic press is started. The hydraulic press starts working, and the output end of the hydraulic press drives the first locking arc plate to move downward, so that the first locking arc plate contacts the joint of the two pipes after the joint. Pressure is generated on the two pipes at the same time. With the combined action of the second locking arc plate, the two pipes are locked and fixed, ensuring that the two pipes will not move significantly during the subsequent welding process, thereby improving the efficiency of pipe joint welding. The above operation achieves a good fixing effect when welding pipes.

[0008] A further feature of this invention is that a cylindrical level is fixedly connected to the outside of the first base plate, and the number of cylindrical levels is two.

[0009] By adopting the above technical solution, two cylindrical levels are used to ensure that the semicircular pipe clamp and the second semicircular pipe clamp remain horizontal to the ground when they are closed together. This also ensures that the two pipe joints are horizontal when they pass through the semicircular pipe clamp and the second semicircular pipe clamp, which facilitates the alignment of the two pipe joints.

[0010] A further feature of this invention is that both the semicircular pipe clamp and the second semicircular pipe clamp are fixedly connected to handles on their exteriors, and the number of handles is two.

[0011] By adopting the above technical solution, the worker holds the handle and uses the action of the rotating shaft to quickly close and open the semi-circular pipe clamp and the second semi-circular pipe clamp.

[0012] A further feature of this invention is that the interior of the semicircular pipe clamp and the second semicircular pipe clamp is provided with threaded cutting edges, and the spacing between each pair of threaded cutting edges is equal.

[0013] By adopting the above technical solution, the threaded blade increases the friction generated by the contact between the two pipes and the inner walls of the semi-circular pipe clamp and the second semi-circular pipe clamp, thus preventing the two pipes from slipping.

[0014] A further feature of this invention is that a bolt base is fixedly connected to the upper surface of the locking post, and a bolt is fixedly connected to the upper surface of the bolt base.

[0015] By adopting the above technical solution, the worker holds the bolt and uses the action of the round shaft to make the clamp quickly lock into the inside of the second jaw, thereby making the semi-circular pipe clamp and the second semi-circular pipe clamp quickly close together.

[0016] A further feature of this invention is that the inside of the rotating handle has a threaded hole, and a stud is fixedly connected to the outside of the locking pin, with the stud penetrating into the inside of the threaded hole.

[0017] By adopting the above technical solution, after the locking pin is locked inside the second jaw, the worker rotates the handle to make the handle move downward. Through the threaded connection between the stud and the threaded hole, the handle moves downward and presses tightly against the outside of the second jaw, thereby locking the locking pin to the outside of the second jaw.

[0018] A further feature of this invention is that the bottom of both the semicircular pipe clamp and the second semicircular pipe clamp are fixedly connected to telescopic support columns, and the number of telescopic support columns is four.

[0019] By adopting the above technical solution, the four telescopic pillars provide support for the semi-circular pipe clamp and the second semi-circular pipe clamp.

[0020] A further feature of this invention is that the telescopic support column has a threaded adjustment hole inside, and a locking stud is provided on the outside of the telescopic support column, with the locking stud extending through the threaded adjustment hole.

[0021] By adopting the above technical solution, after the worker adjusts the height of the telescopic support by hand, he then rotates the locking stud by hand to make the locking stud contact with the inner wall of the telescopic support and lock the inner wall of the telescopic support, preventing the telescopic support from rising and falling arbitrarily after being subjected to force.

[0022] A further feature of this invention is that the base of the telescopic support is provided with wheels, and the number of wheels is four.

[0023] By adopting the above technical solution, the four wheels increase the flexibility of this device.

[0024] A further feature of this invention is that both the semicircular pipe clamp and the second semicircular pipe clamp are fixedly connected to a bracket, and the bracket is fixedly connected to an arc-shaped support clamp.

[0025] By adopting the above technical solution, after the two pipes are aligned, the two arc-shaped support clamps support both ends of the two pipes, increasing the stability of the alignment.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a semi-circular pipe clamp, a rotating shaft, a first base plate, a machine housing, a hydraulic press, a limiting hole, a first locking arc plate, a second base plate, a first jaw, a second jaw, a round shaft, a locking pin, a rotating handle, a second locking arc plate, and a second semi-circular pipe clamp, allows the worker to open and place two pipes inside the semi-circular pipe clamp and the second semi-circular pipe clamp, so that the two pipes are respectively placed on the upper surface of the second locking arc plate. The rotating shaft closes the semi-circular pipe clamp and the second semi-circular pipe clamp, and the round shaft moves the locking pin to lock it inside the second jaw. Then, the two pipes are slowly connected by hand. The butt joint is then constructed. After the butt joint is completed, the hydraulic press is started. The hydraulic press output drives the first locking arc plate downwards, bringing it into contact with the joint of the two butt jointed pipes. Pressure is applied to both pipes simultaneously. With the combined action of the second locking arc plate, the two butt jointed pipes are locked and fixed, ensuring that the two pipes will not move significantly during the subsequent welding process. This improves the efficiency of pipe butt joint welding and achieves a good fixing effect when butt jointing pipes.

[0028] 2. This utility model, through the arrangement of a cylindrical level, handle, threaded blade, bolt base, bolt, threaded hole, stud, telescopic support, threaded adjustment hole, locking stud, wheel, bracket, and arc-shaped support clamp, ensures that the two cylindrical levels remain level with the ground when the semi-circular pipe clamp and the second semi-circular pipe clamp are closed together. This also ensures that the two pipe joints are level when passing through the semi-circular and second semi-circular pipe clamps, facilitating pipe alignment. The worker holds the handle, and the rotating shaft allows the semi-circular and second semi-circular pipe clamps to quickly close and open. The threaded blade increases the friction between the two pipes and the inner walls of the semi-circular and second semi-circular pipe clamps, preventing slippage. The worker holds the bolt, and the rotating shaft allows the locking pin to quickly engage inside the second jaw, thus... The first and second semi-circular pipe clamps are quickly brought together. After the locking pin is engaged inside the second jaw, the worker rotates the handle downwards. Through the threaded connection between the stud and the threaded hole, the downward movement of the handle tightly presses against the outside of the second jaw, thus locking the locking pin to the outside of the second jaw. Four telescopic supports provide support for the first and second semi-circular pipe clamps. The worker adjusts the height of the telescopic supports by hand and then rotates the locking stud to lock the inner wall of the telescopic support, preventing it from rising or falling arbitrarily under force. The four wheels increase the flexibility of the device. After the two pipes are aligned, the two arc-shaped support clamps support both ends of the two pipes, increasing the stability of the alignment. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Reference Figure 1-4A welding and fitting tool for long-distance pipelines includes a semi-circular pipe clamp 1, a rotating shaft 2 externally mounted on the semi-circular pipe clamp 1, a first base plate 3 fixedly connected to the outside of the semi-circular pipe clamp 1, a housing 4 fixedly connected to the outside of the first base plate 3, a hydraulic press 5 fixedly connected inside the housing 4, a limit hole 6 inside the base plate 3, a first locking arc plate 7 externally mounted on the first base plate 3, the output end of the hydraulic press 5 penetrating into the limit hole 6 and fixedly connected to the first locking arc plate 7, a first jaw 9 and a second jaw 10 internally mounted on the semi-circular pipe clamp 1, a round shaft 11 rotatably connected inside the first jaw 9, a locking pin 12 fixedly connected to the outside of the round shaft 11, a rotating handle 13 externally mounted on the semi-circular pipe clamp 1, a second base plate 8 fixedly connected to the outside of the semi-circular pipe clamp 1, a second locking arc plate 14 fixedly connected to the upper surface of the second base plate 8, and a second semi-circular pipe clamp 15 rotatably connected to the outside of the rotating shaft 2. After the worker opens and places the two pipes inside the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15, the two pipes are positioned on the upper surface of the second locking arc plate 14. The semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15 are closed by the rotating shaft 2. The clamping pin 12 moves via the round shaft 11 and locks itself inside the second jaw 10. Then, the worker slowly aligns the two pipes at their joints by hand. After alignment, the hydraulic press 5 is started. The output end of the hydraulic press 5 drives the first locking arc plate 7 downwards, bringing it into contact with the joint of the two aligned pipes. Pressure is applied to both pipes simultaneously. Combined with the action of the second locking arc plate 14, the two aligned pipes are locked and fixed, ensuring that they will not move significantly during the subsequent welding process. This improves the efficiency of pipe alignment welding and achieves excellent fixing effect during pipe welding. Two cylindrical levels 28 are fixedly connected to the outside of the first base plate 3. These levels ensure that the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15 remain horizontal to the ground when they are closed together, and also ensure that the two pipe joints are horizontal when they pass through the inside of the clamps, facilitating pipe alignment. Two handles 16 are fixedly connected to the outside of each of the semi-circular pipe clamps 1 and 15. Workers hold the handles 16, and the pivot 2 allows the clamps to quickly close and open. Threaded blades 17 are provided inside each of the clamps, with equal spacing between each pair. These blades increase the friction between the pipes and the inner walls of the clamps, preventing slippage. A bolt base 18 is fixedly connected to the upper surface of the locking post 12, and a bolt 19 is fixedly connected to the upper surface of the bolt base 18.The worker holds the lever 19, and through the action of the round shaft 11, the locking pin 12 quickly engages inside the second jaw 10, thus quickly closing the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15 together. The rotating handle 13 has a threaded hole 20 inside, and a stud 21 is fixedly connected to the outside of the locking pin 12, penetrating into the threaded hole 20. After the locking pin 12 is engaged inside the second jaw 10, the worker rotates the rotating handle 13, causing it to move downwards. Through the threaded connection between the stud 21 and the threaded hole 20, the downward movement of the rotating handle 13 tightly presses against the outside of the second jaw 10, thus locking the locking pin 12 to the outside of the second jaw 10. Four telescopic supports 22 are fixedly connected to the bottom of both the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15, providing support for them. The telescopic support 22 has a threaded adjustment hole 23 inside, and a locking stud 24 is installed on the outside of the telescopic support 22, extending into the threaded adjustment hole 23. After the worker manually adjusts the height of the telescopic support 22, they then manually rotate the locking stud 24 to make it contact the inner wall of the telescopic support 22, locking the inner wall and preventing the telescopic support 22 from arbitrarily raising or lowering under force. Four wheels 25 are installed at the bottom of the telescopic support 22, increasing the flexibility of the device. Brackets 26 are fixedly connected to the outside of both the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15. Arc-shaped support clamps 27 are fixedly connected to the outside of the brackets 26. After the two pipes are aligned, the two arc-shaped support clamps 27 support both ends of the two pipes, increasing the stability of the alignment.

[0037] In this invention, after the worker places two pipes inside the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15, the two pipes are positioned on the upper surface of the second locking arc plate 14. The semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15 are closed by the rotating shaft 2. The clamping pin 12 moves via the round shaft 11 and locks itself inside the second jaw 10. Then, the worker manually and slowly joins the two pipes at their joints. After the joint is completed, the hydraulic press 5 is started. The output end of the hydraulic press 5 drives the first locking arc plate 7 downwards, bringing it into contact with the joint of the two joined pipes. Pressure is applied to both pipes simultaneously. Combined with the action of the second locking arc plate 14, the joined pipes are locked and fixed, ensuring that the two pipes will not move significantly during the subsequent welding process. This improves the efficiency of pipe joint welding and achieves excellent fixing effect during pipe welding. Two cylindrical levels 28 ensure that the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15 remain horizontal to the ground when they are closed together, and that the two pipe joints are also horizontal when they pass through the interior of the two semi-circular pipe clamps 1 and 15, facilitating pipe alignment. The worker holds the handle 16, and through the action of the rotating shaft 2, quickly closes and opens the semi-circular pipe clamp 1 and 15. The threaded blade 17 increases the friction between the two pipes and the inner walls of the semi-circular pipe clamps 1 and 15, preventing slippage. The worker holds the pull bolt 19, and through the action of the round shaft 11, quickly engages the locking pin 12 inside the second jaw 10, thus quickly closing the semi-circular pipe clamp 1 and 15 together. After the locking pin 12 is engaged inside the second jaw 10, the worker... Rotating the handle 13 causes it to move downwards. Through the threaded connection between the stud 21 and the threaded hole 20, the handle 13 moves downwards and presses tightly against the outside of the second jaw 10, thereby locking the locking pin 12 to the outside of the second jaw 10. The four telescopic supports 22 provide support for the semi-circular pipe clamp 1 and the second semi-circular pipe clamp 15. After the worker adjusts the height of the telescopic supports 22 by hand, the locking stud 24 is rotated by hand to make the locking stud 24 contact the inner wall of the telescopic supports 22 and lock the inner wall of the telescopic supports 22, preventing the telescopic supports 22 from rising and falling arbitrarily under force. The four wheels 25 increase the flexibility of this device. After the two pipes are aligned, the two arc-shaped support clamps 27 provide support for both ends of the two pipes, increasing the stability of the alignment.
