Description

Technical Field

[0001] This utility model belongs to the field of pipeline test tube technology, and in particular relates to a pull-out device for underground pipeline repair. Background Technology

[0002] Pipeline repair refers to the use of various techniques to restore damaged or leaking pipelines to their normal function. The repair includes two techniques: external anti-corrosion layer repair and internal repair. When repairing severely damaged pipelines, it is sometimes necessary to wrap a new pipeline on the outside and then weld the new pipeline in place.

[0003] Chinese Patent Publication No. CN 216201593 U discloses a pull-up device for underground pipeline repair, including clamping plates, internally threaded pipes, and a locking structure. The clamping plates are symmetrically arranged on both sides of the pipeline to be repaired, and one side of each clamping plate has an arc-shaped groove. Screws are symmetrically threaded through the upper and lower sides of each clamping plate, and internally threaded pipes are threaded onto the screws. Handles are integrally formed and symmetrically arranged on the side of one end of each internally threaded pipe. The internally threaded pipes are locked in position by the locking structure. Through the clamping plates, screws, internally threaded pipes, and locking structure, the pull-up structure can be locked and fixed during pull-up work, thereby improving the stability of the pull-up operation and ensuring... To ensure the stability of pipeline repair work and facilitate its operation and use, thereby improving the quality of pipeline repair work, the clamping plate of the aforementioned device has a planar structure. During the clamping process, only the local area where the pipe and the clamping plate are in contact is subjected to pressure, which affects the clamping effect. Moreover, this clamping method requires a specific relative position between the pipes, that is, one side of the pipe must be able to be inserted into the other side of the pipe to achieve clamping. If the diameters of the two pipes do not match or the materials do not allow for insertion, then this clamping device cannot be used, thus limiting its applicability. Therefore, it is necessary to propose a pull-back device for underground pipeline repair to solve the above problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a pull-up device for underground pipeline repair that is highly applicable, easy to operate, and has a relatively simple structure.

[0005] To solve the above-mentioned technical problems, this utility model provides an underground pipeline repair tie rod device, comprising: a base one and a base two, wherein a limit post is fixed on the base one and inserted into the base two, a limit bolt is inserted on the base two, a fixing seat is fixed on the top of the base one and the base two, and a fixing ring is hinged to both sides of the fixing seat, a protective block is provided on the top of the fixing seat, a fixing bolt is threaded to the top of the fixing ring, an adjusting rod is threaded to the side of the fixing ring, and a clamping block is fixed on the adjusting rod inside the fixing ring, and the pipeline is clamped and fixed by the clamping block.

[0006] As a further embodiment of this utility model, the two sets of limiting posts are fixed on the left side of the base to form a U-shaped structure.

[0007] As a further embodiment of this utility model, each set of limiting posts is evenly provided with four sets of limiting grooves that cooperate with the limiting bolts. The limiting posts complete the connection between the base one and the base two by being inserted into the limiting grooves inside the base two.

[0008] As a further embodiment of this utility model, the left side of the second base is provided with two sets of slots for matching limiting posts, and the two sets of limiting bolts are respectively set on both sides of the second base. The design of the limiting posts and limiting bolts allows the distance between the first base and the second base to be adjusted.

[0009] As a further embodiment of this utility model, the two sets of fixing seats are respectively fixed on the top of base one and base two, and each set of fixing seats has two opposing fixing rings hinged on both sides. The fixing rings can be opened to both sides to facilitate the installation and removal of the device and the pipe.

[0010] As a further embodiment of this utility model, each of the fixed rings is threaded with an adjusting rod at the middle position, and each adjusting rod is provided with a clamping block. The clamping block clamps the pipe by adjusting the adjusting rods on both sides of the fixed ring.

[0011] As a further embodiment of this utility model, both the protective block and the clamping block are arc-shaped structures made of non-slip and wear-resistant rubber material. The arc-shaped design of the protective block and the clamping block can better fit the pipe, and the rubber material can reduce wear when clamping the pipe.

[0012] Compared with related technologies, the underground pipeline repair tie rod device provided by this utility model has the following beneficial effects:

[0013] 1. This utility model provides limiting posts and limiting bolts on base one and base two. By inserting the limiting post on base one into the position of base two, the distance between the two sets of fixing rings is adjusted. The two sets of fixing rings clamp the two sides of the pipe respectively, which can more evenly distribute the force on the pipe. By reasonably adjusting the distance, the pipe can be subjected to more even force during the pull process, reducing the risk of pipe deformation or damage caused by unreasonable clamping position, thereby enhancing the stability and reliability of the entire pipeline system.

[0014] 2. This utility model features a condition rod and a clamping block on the fixing ring. The fixing ring can be opened to both sides of the fixing seat, allowing the pipe to be inserted into the fixing ring. The clamping block is adjusted by adjusting the rods on both sides of the fixing ring to hold the pipe in place. The arc-shaped clamping block can better fit the outer surface of the pipe, thus providing a uniform pressure distribution and avoiding localized damage to the pipe. This facilitates quick on-site installation and adjustment. The two sets of fixing rings can fix the pipe from different positions, ensuring a more uniform constraint force on the pipe during the pull-out process. This reduces the shaking and displacement of the pipe caused by single-point fixing. The two sets of fixing rings can be operated independently. If a problem is found with the pull-out device or the pipe during use, the two sets of fixing rings can be inspected and repaired separately without disassembling the entire device, reducing maintenance costs and workload and improving work efficiency.

[0022] Please refer to the following: Figure 1-5A pull-out device for underground pipeline repair includes: a base 1 and a base 2. A limiting post 3 is fixed on the base 1 and inserted into the base 2. A limiting bolt 4 is inserted into the base 2. The distance between two sets of fixing rings 7 is adjusted by positioning the limiting post 3 on the base 1 in the base 2. The two sets of fixing rings 7 clamp the two sides of the pipeline 11, which can more evenly distribute the force applied to the pipeline 11. By reasonably adjusting the distance, the force on the pipeline 11 can be more evenly distributed during the pull-out process, reducing deformation or damage to the pipeline 11 caused by improper clamping positions. Bad risks; the top of the base 1 and the base 2 are fixed with a fixed seat 5, and the fixed seat 5 is hinged with a fixed ring 7 on both sides. The top of the fixed seat 5 is provided with a protective block 6. The top of the fixed ring 7 is threaded with a fixed bolt 10. The side of the fixed ring 7 is threaded with an adjusting rod 8, and a clamping block 9 is fixed on the adjusting rod 8 inside the fixed ring 7. The pipe 11 is clamped and fixed by the clamping block 9. The two sets of fixed rings 7 can fix the pipe 11 from different positions, so that the pipe 11 is subjected to a more uniform constraint force during the pull process, reducing the shaking and displacement of the pipe 11 caused by single-point fixation.

[0023] Two sets of limiting posts 3 are fixed on the left side of base 1 to form a U-shaped structure. Each set of limiting posts 3 is evenly provided with four sets of limiting grooves that cooperate with limiting bolts 4. The left side of base 2 has two sets of slots that cooperate with limiting posts 3, and the two sets of limiting bolts 4 are respectively set on both sides of base 2. When the pipe 11 is pulled, by separating base 1 and base 2 to a suitable position, the limiting posts 3 above base 1 are threaded and fixed by inserting the limiting bolts 4 into base 2, thereby adjusting the distance between base 1 and base 2. The two sets of fixing rings 7 on base 1 and base 2 respectively clamp the two sides of the pipe 11, which can more evenly distribute the force on the pipe 11. By reasonably adjusting the distance, the force on the pipe 11 can be more even during the pulling process, reducing the risk of deformation or damage to the pipe 11 due to unreasonable clamping position.

[0024] Two sets of fixing seats 5 are fixed to the top of base 1 and base 2 respectively. Each set of fixing seats 5 has two opposing fixing rings 7 hinged on both sides. Each fixing ring 7 has an adjusting rod 8 threaded in the middle. Each adjusting rod 8 is equipped with a clamping block 9. The protective block 6 and the clamping block 9 are arc-shaped structures made of non-slip and wear-resistant rubber. When pulling the pipe 11, the two fixing rings 7 on each set of fixing seats 5 are opened to both sides. The fixing rings 7 are installed from the bottom of the pipe 11 and fixed with fixing bolts 10. By rotating the adjusting rods 8 on both sides, the clamping blocks 9 are driven to clamp and fix the pipe 11 in the middle. The two sets of fixing rings 7 can fix the pipe 11 from different positions, so that the pipe 11 is subjected to a more uniform constraint force during the pulling process, reducing the shaking and displacement of the pipe 11 caused by single-point fixing.

[0025] When installing pipes, first fix one set of clamping structures to the pipe, then adjust the position of the other set of clamping structures and fix it, making the installation process more convenient. When it is necessary to disassemble the pull-out device, both sets of clamping structures can be released separately, making the operation more flexible.

[0026] Working principle: Open the two fixing rings 7 on each set of fixing seats 5 to both sides, install the fixing rings 7 from the bottom of the pipe 11 and fix the two fixing rings 7 with fixing bolts 10, separate the base 1 and base 2 and adjust the appropriate distance, and use the limit bolt 4 to insert on the base 2 to thread the limit post 3 above the base 1.

[0027] The adjusting rods 8 on both sides of the rotating fixing ring 7 on the base 1 and the base 2 respectively drive the clamping block 9 to clamp and fix the middle pipe 11.

[0028] After completing the repair of pipe 11, the two fixing rings 7 on the fixing seats 5 on base 1 and base 2 are opened by fixing bolts 10, thereby removing the device from pipe 11.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments, or they can be used directly or indirectly, without departing from the principles and spirit of the present invention. In other related technical fields, the scope of the present invention is defined by the appended claims and their equivalents, and they are similarly included within the patent protection scope of the present invention.
