Description

Technical Field

[0001] This utility model relates to the field of long-distance pipeline technology, and in particular to a pipeline alignment device for a pipeline underground water-line conveying device. Background Technology

[0002] In pipeline laying construction, pipe butt welding is a crucial preliminary step to ensure welding quality. Currently, external pipe butt clamps are commonly used. As a specialized tool, their main function is to clamp, align, and fix the two pipe ends to be welded, ensuring that the butt joint meets the process requirements for concentricity, misalignment, and butt gap. These traditional butt clamps typically employ a clamp-type structure, with two semi-circular rings connected at one end by a hinge, and the other end locked with bolts or quick-locking clips, forming a clamshell-like opening and closing structure. Power sources include manual, pneumatic, or hydraulic. During installation, it must be placed close to the weld joint and fixed on both sides. While this equipment plays a role in improving the accuracy of pipe assembly, its inherent structural characteristics result in significant limitations in construction efficiency, ease of operation, and welding adaptability.

[0003] In the prior art, Chinese patent document CN119196400A discloses a pipeline laying assembly line and construction method in plain areas. The conveying device sequentially connects a pipeline frame, a welding platform, a flaw detection platform, a jointing platform, a trench support, and a traction device. The pipeline is stored on the pipeline frame and transported to the welding platform for welding connection. Welding quality is inspected on the flaw detection platform, and anti-corrosion treatment is performed on the jointing platform. Finally, the pipeline is lowered into the trench via the trench support and connected to the bottom of an excavator via the traction device, which then pulls the pipeline for laying. This application solves the problems of excessive road width occupation and long construction period associated with traditional pipeline laying. This application can save construction space, improve construction efficiency, and reduce construction costs. However, the clamp structure must be installed tightly against the weld seam, severely obstructing the welder's view and requiring multiple adjustments to the welding torch angle during welding, resulting in poor practicality. Therefore, this utility model discloses a pipeline alignment device for a pipeline laying assembly line conveying device to solve the problems of existing alignment devices obstructing the weld seam and low disassembly and assembly efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a pipe alignment device for a pipeline underground conveying device, so as to solve the problems of existing alignment devices blocking weld seams and low disassembly and assembly efficiency.

[0005] To achieve the above objectives, this utility model provides a pipe alignment device for a pipeline underground conveying system, comprising: two bracket units disposed opposite to each other on both sides of the weld joint, and a column for supporting the bracket units; each bracket unit includes an arc-shaped bracket for supporting the pipe body, and the arc-shaped bracket is provided with at least three adjustable positioning components, the ends of the positioning components pointing towards the center of the arc-shaped bracket, for fine adjustment and clamping of the pipe body from different directions.

[0006] Preferably, the positioning component includes three positioning posts, namely a bottom positioning post and two side positioning posts; the bottom positioning post is vertically disposed at the bottom center of the arc-shaped bracket, and the two side positioning posts are symmetrically disposed on the upper sides of the arc-shaped bracket.

[0007] Preferably, the positioning component is a threaded adjustment structure, including a connector with internal threads. The connector is fixed on the arc-shaped bracket and is threadedly engaged with the bottom positioning post and the side positioning post, respectively. Rotating the positioning post allows its end to move linearly in the direction pointing towards the center of the circle.

[0008] Preferably, the bottom positioning post and the side positioning post are provided with positioning heads at the ends away from the tube body. The positioning heads are made of metal material, and the positioning post is provided with a clamping pad at the end near the tube body. The clamping pad is made of flexible material.

[0009] Preferably, the arc-shaped bracket is fixedly connected to the top of the column via a connecting part, and the height of the column is adjustable.

[0010] Preferably, the column is a rotatable internally threaded telescopic rod.

[0011] The beneficial effects of this utility model are: The separate bracket design ensures an unobstructed welding operation space, overcoming the shortcomings of traditional external alignment devices that interfere with welding. Combined with a three-point positioning structure, it precisely controls alignment parameters. A threaded fine-tuning mechanism enables rapid single-person operation, reducing the alignment and disassembly time for large-diameter pipes from 45-60 minutes to 5 minutes, thus reducing personnel requirements. Because the device is fixed in position, it eliminates the need for relocation and disassembly, significantly improving the continuity of assembly line operations. Its adjustable column and positioning components allow one set of equipment to accommodate multiple pipe diameters, reducing equipment procurement costs. The integrated design eliminates hoisting safety risks and protects the pipe's anti-corrosion layer with clamping pads, ultimately shortening the construction cycle and reducing overall costs.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0017] This utility model provides, for example Figures 1 to 3 The pipe fitting device for a pipeline underground pipeline conveying device shown includes: two bracket units 1 arranged opposite to each other on both sides of the weld joint, and a column 2 for supporting the bracket units 1; the bracket unit 1 includes an arc-shaped bracket 4 for supporting the pipe body 3, and the arc-shaped bracket 4 is provided with at least three adjustable positioning components 5, the ends of the positioning components 5 pointing to the center of the arc-shaped bracket 4, for fine adjustment and clamping of the pipe body 3 from different directions; In existing technology, a conveying device is used that sequentially connects a pipeline rack, a welding platform, a flaw detection platform, a jointing platform, a trench support, and a traction device. The pipeline is stored on the pipeline rack and transported to the welding platform for welding connections. Welding quality is inspected on the flaw detection platform, and anti-corrosion treatment is performed on the jointing platform. Finally, the pipeline is lowered into the trench via the trench support and connected to the bottom of an excavator via the traction device, where the excavator pulls the pipeline for laying. This application can improve construction efficiency and reduce construction costs. (See attached document for reference.) Figure 1 As shown, the pipeline conveying device transports the pipe body 3 to the welding platform. Two bracket units 1 are positioned opposite each other on both sides of the weld joint and are fixed to the ground or the assembly line frame by the columns 2 to ensure stability. Fine-tuning is performed by the positioning components 5: the bottom positioning column 6 moves vertically to correct the misalignment of the bottom pipe opening, while the two side positioning columns 7 rotate synchronously to control concentricity. All three are connected to the connector 8 through a threaded structure to achieve linear movement of the end along the center direction, eliminating the hoisting step required by traditional pipe alignment devices, shortening the alignment time of large-diameter pipes, and significantly improving the continuity of the assembly line. After fine-tuning, the clamping pad made of flexible material gently clamps the pipe body 3 to prevent damage to the anti-corrosion layer, and the welding operation begins immediately. Since the bracket unit 1 is located outside the weld joint, the weld area is completely unobstructed, and the welder can operate continuously. The entire process can be completed by a single person, reducing personnel requirements. Furthermore, the adjustable columns 2 can adapt to various pipe diameters, ultimately achieving the comprehensive benefit of shortening the construction cycle.

[0018] Furthermore, in this example, such as Figure 2 , Figure 3 As shown, the positioning component 5 includes three positioning posts: a bottom positioning post 6 and two side positioning posts 7. The bottom positioning post 6 is vertically positioned at the bottom center of the arc-shaped bracket 4, and the two side positioning posts 7 are symmetrically positioned on the upper sides of the arc-shaped bracket 4. The positioning component 5 is a threaded adjustment structure, including a connector 8 with internal threads. The connector 8 is fixed on the arc-shaped bracket 4 and threadedly engages with the bottom positioning post 6 and the side positioning posts 7 respectively. Rotating the positioning head 9 drives the positioning post to move its end in a straight line in the direction pointing to the center of the circle. The bottom positioning post 6 and the side positioning post 7 are provided with positioning heads 9 at the ends away from the tube body 3. The positioning heads 9 are made of metal material, and the end of the positioning post 7 near the tube body 3 is provided with a clamping pad. The clamping pad is made of flexible material. The arc-shaped bracket 4 is fixedly connected to the top of the column 2 through a connecting part 10. The height of the column 2 is adjustable, and the column 2 is a rotatable internally threaded telescopic rod. The operator first places the two bracket units 1 opposite each other on both sides of the weld joint. The height is adjusted by the column 2 to match the supporting surface of the arc-shaped bracket 4 with the outer diameter of the pipe body 3, thus initially stabilizing the pipe body. Then, the fine adjustment stage begins: the bottom positioning column 6 is rotated first, and it advances linearly through the threaded engagement of the connector 8, lifting the bottom of the pipe body 3 to correct the misalignment. At the same time, the two side positioning columns 7 are rotated simultaneously, and the horizontal position of the pipe body 3 is finely adjusted using the symmetrical thread structure to ensure concentricity. Due to the precision of the thread adjustment, the alignment parameters are met in one go, avoiding the time-consuming problem of repeated adjustments in the traditional method, and improving the alignment efficiency. Through the stable connection of the connecting part 10, the entire system remains stable in the production line, supporting the integrated operation of "conveying-aligning-welding", which shortens the construction cycle.

[0019] The alignment device is integrated into the production line, its function focused on the precise vertical positioning and clamping of the positioned tubes. The horizontal movement and distance adjustment of the tubes on the production line are achieved by a separate pulley conveyor system. For example... Figure 1 As shown, pipe body 3 is supported and transported smoothly and continuously forward by a pulley system installed on the assembly line until it reaches the welding station. The alignment device and the conveying system each perform their respective functions and work together: the pulley system is responsible for the "movement" of the pipe, achieving macroscopic control of the weld distance; the alignment device is responsible for the "centering" of the pipe ends, achieving fine-tuning and tightening in all directions. This division of labor and cooperation ensures both alignment accuracy and the efficiency and continuity of the entire pipe laying process.
