Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology, specifically a rapid pipeline alignment and assembly device. Background Technology

[0002] In pipeline construction, butt welding of two or more pipes is a fundamental procedure. The core requirements for pipe assembly are ensuring concentricity (alignment) of the pipe ends and a reasonable butt gap, which directly determines the welding quality and the long-term operational safety of the pipeline system.

[0003] Currently, pipeline alignment on construction sites is mainly done manually. Operators typically use simple tools such as crowbars, hand hoists, and jacks, along with visual inspection and steel rulers, to repeatedly adjust the pipeline position. This traditional method has significant drawbacks: First, it is extremely inefficient, with the adjustment process being time-consuming and labor-intensive, especially in the construction of large-diameter or heavy pipelines, often requiring multiple people working together for extended periods. Second, alignment accuracy is difficult to guarantee, heavily influenced by the operator's experience and skill level, easily leading to excessive misalignment of pipe ends and welding defects. Third, existing pipeline alignment fixtures or equipment are either complex in structure, bulky, and expensive, or only suitable for a single pipe diameter and inconvenient to move, unable to adapt to the complex and ever-changing environment of construction sites. Therefore, there is an urgent need for a rapid pipeline alignment and assembly device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a device for rapid alignment and assembly of pipelines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rapid pipe alignment and assembly device includes a base plate, the bottom of which is provided with several sets of casters, two sets of which are symmetrically arranged. The device also includes:

[0007] The connecting mechanism has two ends connected to the two sets of base plates respectively, and is used to connect the two sets of base plates together;

[0008] The positioning mechanism is connected to the base plate and abuts against the ground, and is used to position the base plate.

[0009] Cylinder 1, one end of which is rotatably connected to the base plate;

[0010] The connecting plate is rotatably connected to the base plate and also rotatably connected to the other end of the cylinder.

[0011] A rotating roller is rotatably connected to a connecting plate, and the rotating roller is provided in several groups;

[0012] The jacking mechanism, connected to the base plate and abutting against one end of the pipe, is used to push the pipe to connect with another set of pipes.

[0013] As a further aspect of the present invention: the connecting mechanism includes:

[0014] The lever connects to the base plate;

[0015] A slot is formed on the base plate, and the slot engages with the locking rod.

[0016] The fixing component is connected to the two sets of base plates at both ends.

[0017] As a further aspect of the present invention: the fixing component includes:

[0018] A rotating plate is connected to a set of the base plates;

[0019] The sliding sleeve connects to the rotating plate;

[0020] A spring, one end of which is connected to a rotating plate;

[0021] The folding rod is slidably connected to the sliding sleeve and to the other end of the spring;

[0022] The sleeve connects to another set of base plates and engages with the folding rod.

[0023] As a further aspect of the present invention: the positioning mechanism includes:

[0024] Threaded sleeve, connected to the base plate;

[0025] The threaded rod is threadedly connected to the threaded sleeve.

[0026] The abutment plate connects to the bottom end of the threaded rod and abuts against the ground.

[0027] As a further aspect of the present invention: the pushing mechanism includes:

[0028] Fixed groove plate, connected to the base plate;

[0029] The sliding block is slidably connected to the fixed groove plate;

[0030] Cylinder 2, one end is connected to the sliding block, and the other end is connected to the fixed groove plate;

[0031] The push plate is rotatably connected to the sliding block;

[0032] The magnetic assembly is connected to the sliding block at one end and to the push plate at the other end.

[0033] As a further aspect of the present invention: the magnetic attraction component includes:

[0034] Magnet one is connected to the push plate;

[0035] Magnet 2 is connected to the sliding block and is magnetically attracted to Magnet 1.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] This invention achieves precise alignment of pipes in both vertical and horizontal directions, significantly improving assembly accuracy. It employs two symmetrically arranged base plates, each with an independently mounted rotating connecting plate driven by a cylinder and multiple sets of rotating rollers. By independently controlling the extension and retraction of the piston rods of the cylinders on both sides, the connecting plate can be precisely driven to rotate around its hinge point, thereby continuously and steplessly adjusting the support height of the rotating rollers. This design allows for fine vertical adjustment of the pipes placed on the rotating rollers, ensuring that the centerlines of the two pipes are at the same horizontal level, avoiding the low accuracy and repeated trial-and-error problems associated with traditional methods that rely on visual inspection and shims.

[0038] The jacking mechanism is rationally designed to achieve stable and controllable axial assembly of the pipeline without interfering with pipeline loading and unloading. Each base plate is equipped with a jacking mechanism consisting of a fixed groove plate, a sliding block, a second cylinder, a rotatable push plate, and a magnetic assembly. When assembly is required, simply flip the push plate upwards to a vertical position; magnet one and magnet two automatically engage and lock, keeping the push plate stable and upright. At this time, cylinder two drives the sliding block and push plate to move towards the pipeline end, pushing the pipeline to slide axially along the rotating roller. Due to the low friction characteristics of the rotating roller, the pipeline moves smoothly with minimal resistance. Furthermore, by controlling the stroke of cylinder two, the pipe joint gap can be precisely adjusted to meet different welding process requirements. When assembly is complete or the device needs to be removed, the magnetic force can be easily overcome to flip the push plate flat, completely detaching it from the pipeline end face, avoiding interference with pipeline hoisting or device removal.

[0039] The device can be quickly assembled and disassembled, balancing operational rigidity and ease of removal: This invention achieves rapid insertion and positioning of two sets of base plates through a connecting rod and slot, and then achieves one-button locking and unlocking through a fixing assembly consisting of a rotating plate, sliding sleeve, spring, folding rod, and clamping sleeve. The spring constantly applies a preload force to the folding rod towards the clamping sleeve, ensuring reliable locking and preventing accidental loosening during operation. When it is necessary to remove the device, simply pull the folding rod upwards to disengage it from the clamping sleeve, allowing the two sets of base plates to be quickly separated and removed from under the installed (welded) pipe. This design ensures the overall rigidity and stability of the device during assembly operations and solves the problem of traditional integrated tooling being difficult to remove from under long pipes. It is particularly suitable for construction sites with continuous long pipes or limited space, improving the continuity of the construction process. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the embodiments of this invention, please refer to Figures 1 to 4 A rapid alignment and assembly device for pipelines includes a base plate 1, the bottom of which is provided with several sets of moving wheels 2, the base plate 1 having two sets symmetrically arranged, and further includes:

[0047] The connecting mechanism is connected at both ends to the two sets of base plates 1 respectively, and is used to connect the two sets of base plates 1 together;

[0048] The positioning mechanism is connected to the base plate 1 and abuts against the ground, and is used to position the base plate 1.

[0049] Cylinder 13, one end of which is rotatably connected to base plate 1;

[0050] The connecting plate 14 is rotatably connected to the base plate 1 and rotatably connected to the other end of the cylinder 13;

[0051] Rotating roller 15 is rotatably connected to connecting plate 14, and the rotating roller 15 is provided with several sets;

[0052] The jacking mechanism is connected to the base plate 1 and abuts against one end of the pipe, and is used to push the pipe to connect with another set of pipes.

[0053] The two sets of base plates 1 are connected together using a connecting mechanism, and the positioning mechanism positions the base plates 1 to prevent displacement during operation. When the piston rod of cylinder 13 extends or retracts, it drives the connecting plate 14 to rotate around its hinge point with the base plate 1, thereby changing the support height of the rotating roller 15. The pipes to be connected are placed on these rotating rollers 15. By adjusting the cylinders 13 on both sides of the base plates 1, the two pipes can be precisely aligned in the vertical direction (i.e., the center height is consistent). The setting of the rotating roller 15 allows the pipes to move easily along the axial direction, reducing friction. The pushing mechanism pushes the pipes, allowing them to slide smoothly forward on the rotating rollers 15 until they contact the end of the other set of pipes, achieving precise alignment. After the pipe openings are aligned and the gaps are adjusted to be qualified, the pipes are installed and fixed (or welded). After completion, the connecting mechanism is released, the two sets of base plates 1 are separated, and the device can be moved out from under the installed pipes.

[0054] As one embodiment of the present invention, please refer to Figures 1 to 3 The connecting mechanism includes:

[0055] Rod 3 is connected to base plate 1;

[0056] The slot 4 is formed on the base plate 1, and the slot 4 is engaged with the lever 3.

[0057] The fixing component is connected at both ends to the two sets of base plates 1 respectively;

[0058] The fixing component includes:

[0059] Rotating plate 5 is connected to a set of the base plates 1;

[0060] The sliding sleeve 6 is connected to the rotating plate 5;

[0061] Spring 7, one end of which is connected to rotating plate 5;

[0062] The folding rod 8 is slidably connected to the sliding sleeve 6 and to the other end of the spring 7;

[0063] The sleeve 9 is connected to the other set of base plates 1 and is engaged with the folding rod 8.

[0064] When the two sets of base plates 1 are close together, the locking rod 3 can be inserted into the locking slot 4 to achieve initial positioning. Then, the worker pulls the folding rod 8 upward, the spring 7 deforms, and then the folding rod 8 is rotated. The rotating plate 5 rotates synchronously. When the other end of the folding rod 8 rotates to the top of the locking sleeve 9, the folding rod 8 is released. Under the reaction force of the spring 7, the folding rod 8 moves downward and is locked into the locking sleeve 9, thereby firmly connecting the two sets of base plates 1 into a whole.

[0065] As one embodiment of the present invention, please refer to Figure 1 The positioning mechanism includes:

[0066] Threaded sleeve 10 is connected to base plate 1;

[0067] Threaded rod 11 is threadedly connected to threaded sleeve 10;

[0068] The abutment plate 12 is connected to the bottom end of the threaded rod 11 and abuts against the ground.

[0069] The operator rotates the threaded rod 11, driving the abutment plate 12 to move downward until it is firmly pressed against the ground, thus stabilizing the device during operation.

[0070] In this embodiment, the lower surface of the abutment plate 12 may be provided with anti-slip teeth or rubber pads to increase friction and prevent the device from shifting during operation; the levelness of the device can be finely adjusted by adjusting the positioning mechanisms on the two base plates 1 respectively.

[0071] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The pushing mechanism includes:

[0072] Fixed groove plate 16 is connected to base plate 1;

[0073] The sliding block 17 is slidably connected to the fixed groove plate 16;

[0074] Cylinder 2 18, one end is connected to sliding block 17, and the other end is connected to fixed groove plate 16;

[0075] Push plate 19 is rotatably connected to sliding block 17;

[0076] The magnetic suction assembly is connected at one end to the sliding block 17 and at the other end to the push plate 19;

[0077] The magnetic attraction component includes:

[0078] Magnet 20 is connected to push plate 19;

[0079] Magnet 21 is connected to slider 17 and magnetically attracted to magnet 20.

[0080] In the initial state, push plate 19 is placed horizontally, and magnet 1 20 and magnet 2 21 are separated;

[0081] To achieve axial movement of the pipes and complete the final assembly, the operator rotates the push plate 19 to a vertical position. At this time, magnet 1 20 and magnet 21 are magnetically attracted together, ensuring that the push plate 19 is in a vertical position. When the pipe needs to be pushed, the piston rod of cylinder 2 18 retracts, pulling the sliding block 17 and the push plate 19 together to move towards the end of the pipe. The end face of the push plate 19 abuts against the end of the pipe, thereby driving the pipe to slide smoothly forward on the rotating roller 15 until it contacts the end of another set of pipes, achieving precise assembly.

[0082] The working principle of this invention is as follows: Insert the locking rod 3 on one set of base plates 1 into the locking groove 4 on the other set of base plates 1 to achieve initial positioning. Then, operate the fixing component: pull the folding rod 8 upward to compress the spring 7 and slide it up along the sliding sleeve 6. Rotate the rotating plate 5 to align the hook end of the folding rod 8 with the sleeve 9. Release the folding rod 8. Under the restoring force of the spring 7, the folding rod 8 automatically locks into the sleeve 9, firmly connecting the two sets of base plates 1 into a rigid whole.

[0083] Then, rotate the threaded rods 11 on the two sets of base plates 1 respectively to drive the abutment plate 12 to move downward until it is firmly against the ground, fix the whole device and level it; use lifting equipment to lift the two pipes to be connected onto the rotating rollers 15 on the two sets of base plates 1 respectively. At this time, the pipes are supported by multiple sets of freely rotating rollers 15, which facilitates subsequent axial movement.

[0084] The cylinders 13 on the two base plates 1 are activated respectively. The piston rods of the cylinders 13 extend and retract, driving the connecting plate 14, which is rotatably connected to it, to rotate up or down around the hinge point on the base plate 1. The connecting plate 14 drives the rotating roller 15 on it to rise and fall, thereby precisely adjusting the center height of the pipe placed on the rotating roller 15. By independently controlling the cylinders 13 on both sides, the center lines of the pipe openings of the two pipes are made to be at the same horizontal height, thus completing the precise vertical alignment.

[0085] Manually flip the push plate 19 of the jacking mechanism from a horizontal position to a vertical position. At this time, the magnet 20 on the push plate 19 and the magnet 21 on the sliding block 17 are attracted by magnetic force, firmly holding the push plate 19 in the vertical working position. Start the cylinder 18. The piston rod of the cylinder 18 retracts (or extends, depending on the installation direction), pulling the sliding block 17 to move towards the end of the pipe in the fixed groove plate 16. After the end face of the push plate 19 abuts against the end of the pipe, it continues to push the pipe to slide smoothly axially along the rotating roller 15 until the pipe ends of the two pipes reach the preset mating gap. By precisely controlling the stroke of the cylinder 18, it can be ensured that the assembly gap meets the welding requirements.

[0086] After the pipe opening is aligned and the gap is adjusted to be within acceptable limits, spot welding is performed for fixation, followed by formal welding. After welding, manually overcome the magnetic force to flip and flatten the push plate 19, allowing it to detach from the pipe end. Then, pull the bending rod 8 upward to disengage it from the clamping sleeve 9, rotate the rotating plate 5 in the opposite direction to release the locking of the fixing component, and pull the clamping rod 3 out of the clamping slot 4. At this point, the two sets of base plates 1 are completely separated, and the device can be moved out from under the welded pipe in either a vertical or horizontal direction, completing the entire operation process.

[0087] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

[0088] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
