Description

Technical Field

[0001] This utility model relates to the field of pipeline dragging technology, and in particular to a horizontal directional drilling pipeline dragging connection device. Background Technology

[0002] Horizontal directional drilling (HDD) is a trenchless construction technique for laying pipelines underground, particularly suitable for crossing rivers, roads, railways, and other obstacles. During HDD construction, the pipeline pull-back connection device is a key component for completing the pipeline pullback phase. PE pipes are commonly used in HDD. Existing methods for pulling back PE pipes involve fabricating a pull-back head, placing the pipe within it, and heat-fusion bonding it before pulling the pipe. However, since various specifications of PE pipes are often required on-site, the number of pull-back head models needed increases accordingly, leading to high overall processing costs. Furthermore, the pull-back heads are heavy, bulky, and require considerable time for heat fusion installation, making them inconvenient to transport and use, increasing labor costs, reducing work efficiency, and increasing the complexity of construction organization. Therefore, this invention proposes a horizontal directional drilling pipeline pull-back connection device. Utility Model Content

[0003] The purpose of this utility model is to address the problems in the background technology where multiple specifications and models of PE pipes are often required on site, which in turn increases the number of towing head models to be processed, resulting in high overall processing costs. At the same time, the towing heads are heavy, bulky, and require a certain amount of time for installation and heat fusion, making them inconvenient to transport and use, increasing labor costs, reducing work efficiency, and increasing the complexity of construction organization. The present invention proposes a horizontal directional drilling pipe towing connection device.

[0004] The technical solution of this utility model is as follows: A horizontal directional drilling pipe dragging and connecting device, comprising: a dragging assembly, the dragging assembly including a dragging side plate and a pipe body, one end of the dragging side plate being connected to a first clamping plate, the end of the first clamping plate away from the dragging side plate being connected to a connecting folding plate, the end of the connecting folding plate away from the first clamping plate being connected to a connecting end plate, and a cable sleeve being connected to the inner side of the connecting end plate, the cable sleeve being a cylindrical hollow structure; a positioning assembly, the positioning assembly including a positioning side plate and a mounting horizontal plate, one side of the positioning side plate being connected to a clamping inner plate, and the inner side of the mounting horizontal plate having a threaded hole for a second bolt to pass through; and an adjusting assembly, the adjusting assembly including a threaded rod, one end of the threaded rod being connected to a handwheel, the end of the dragging side plate near the positioning side plate being connected to a limit rod, one end of the positioning side plate being connected to a second clamping plate, and the inner side of the second clamping plate being provided with a first bolt.

[0005] Optionally, a limiting side plate is connected to one end of the positioning side plate near the dragging side plate, and threaded holes of the same size that match the second bolt are opened on the inner side of both the mounting cross plate and the dragging side plate.

[0006] Optionally, the positioning side plates are used in pairs as a group, and the positioning side plates are connected to the adjacent ends of the same group of dragging side plates by a limiting rod.

[0007] Optionally, an anti-slip pad layer is provided on the inner side of the clamping inner plate. The anti-slip pad layer is an arc-shaped rubber layer, and the spacing between two adjacent anti-slip pad layers is the same.

[0008] Optionally, the end of the threaded rod away from the handwheel passes through the two positioning side plates and extends to be rotatably connected to the positioning side plates via bearings. The threaded rod is rotatably connected to both the through-passing dragging side plate and the positioning side plate via threads.

[0009] Optionally, the limiting rods are used in pairs as a group, and the limiting rods in the same group are symmetrically arranged on both sides of the threaded rod. Each limiting rod is simultaneously slidably connected to the positioning side plates of the two pieces, and each limiting rod is simultaneously connected to the adjacent end of the dragging side plates of the two pieces.

[0010] Optionally, a second clamping plate is connected to one end of the positioning side plate near the connecting folding plate. The second clamping plate and the inner side of the first clamping plate are provided with threaded holes of the same size that match the first bolt.

[0011] Optionally, the threaded rod is a double-ended threaded rod.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model, through its adjustable towing component, positioning component, and adjustment component, can adapt to various specifications of PE pipes, greatly reducing the processing costs caused by manufacturing different towing heads. Its lightweight structure reduces handling and labor costs, significantly lowering the overall construction cost.

[0014] Furthermore, this utility model allows each limiting rod to be slidably connected to two positioning side plates, enabling the positioning side plates to move flexibly around the limiting rods. For PE pipes of different diameters, operators can easily and quickly adapt the pipes by moving the positioning side plates, eliminating the need for complex disassembly and reinstallation. Simply adjusting the position of the positioning side plates on the limiting rods quickly changes the pipe's positioning space to accommodate the new pipe size. This flexible adjustment method greatly improves the adaptability to different pipe specifications during construction, avoiding the cumbersome process of remaking or adjusting the entire connection device due to changes in pipe specifications. This significantly improves construction efficiency and reduces construction time and costs. Attached Figure Description

[0030] Example

[0031] like Figures 1 to 6 As shown, this utility model proposes a horizontal directional drilling pipe dragging connection device, comprising: a dragging assembly 1, which includes a dragging side plate 11 and a pipe body 16. The dragging side plate 11 serves as a basic load-bearing component, with a first clamping plate 12 connected to one end. The end of the first clamping plate 12 away from the dragging side plate 11 is connected to a connecting folding plate 13, which is bent. This design allows the connecting end plate 14 to connect to the external dragging rope at a suitable angle. The end of the connecting folding plate 13 away from the first clamping plate 12 is connected to the connecting end plate 14. A cable sleeve 15 is connected to the inner side of the connecting end plate 14. The cable sleeve 15 is a cylindrical hollow structure, which facilitates the passage of the rope and ensures stable tension of the rope during subsequent dragging of the pipe body 16.

[0032] Furthermore, this embodiment also includes a positioning component 2, comprising a positioning side plate 21 and a mounting horizontal plate 25. One side of the positioning side plate 21 is connected to a clamping inner plate 22. In actual operation, the movement of the positioning side plate 21 will cause the clamping inner plate 22 to move closer to or further away from the inner wall of the pipe body 16. The inner side of the mounting horizontal plate 25 has threaded holes for the second bolt 26 to pass through. After clamping the pipe body 16, the mounting horizontal plate 25 is connected to the dragging side plate 11 via the second bolt 26. During the dragging process of the pipe body 16, it protects both ends of the pipe body 16, preventing damage due to uneven force during dragging.

[0033] Secondly, the horizontal directional drilling pipe dragging connection device also includes an adjustment component 3, including a threaded rod 31, which is a double-ended screw. One end of the threaded rod 31 is connected to a handwheel 32, and the operator controls the rotation of the threaded rod 31 by turning the handwheel 32. The end of the dragging side plate 11 near the positioning side plate 21 is connected to a limit rod 34, and one end of the positioning side plate 21 is connected to a second clamping plate 35. The inner side of the second clamping plate 35 is provided with a first bolt 33. During operation, turning the handwheel 32 drives the threaded rod 31 to rotate. Since the threaded rod 31 is threadedly connected to both the dragging side plate 11 and the positioning side plate 21, it will drive the two positioning side plates 21 to gradually move away from each other, thereby achieving clamping of the inner wall of the pipe body 16.

[0034] like Figures 1 to 3 As shown, a limiting plate 23 is connected to one end of the positioning side plate 21 near the dragging side plate 11. The limiting plate 23 is designed to limit the length of the positioning side plate 21 inserted into the pipe body 16, preventing excessive insertion of the positioning side plate 21 and causing unnecessary damage to the inside of the pipe. Both the mounting horizontal plate 25 and the dragging side plate 11 have threaded holes of the same size that match the second bolt 26 on their inner sides, facilitating the subsequent connection and fixing of the mounting horizontal plate 25 and the dragging side plate 11.

[0035] like Figure 2 and Figure 3 As shown, the positioning side plates 21 are used in pairs. The positioning side plates 21 are connected to the adjacent ends of the same group of dragging side plates 11 by limiting rods 34. Each limiting rod 34 is simultaneously slidably connected to two positioning side plates 21, so that the positioning side plates 21 can move around the limiting rod 34 as an axis, thereby ensuring the stability of the movement of the positioning side plates 21.

[0036] like Figures 2 to 5 As shown, an anti-slip pad layer 24 is provided on the inner side of the clamping inner plate 22. The anti-slip pad layer 24 is an arc-shaped rubber layer. The spacing between two adjacent anti-slip pad layers 24 is the same. When the anti-slip pad layer 24 is tightly attached to the inner wall of the pipe body 16, it can achieve double clamping and fixing of the inner wall of the pipe body 16, thereby enhancing the stability and reliability of clamping.

[0037] In addition, the end of the threaded rod 31 away from the handwheel 32 passes through the two positioning side plates 21 and extends to be rotatably connected to the positioning side plates 21 via bearings. The threaded rod 31 is rotatably connected to the through dragging side plate 11 and the positioning side plate 21. This connection method allows for precise control of the movement distance of the positioning side plate 21 when the threaded rod 31 is rotated, thereby adapting to pipes of different diameters.

[0038] Furthermore, the limiting rods 34 are used in pairs, and the limiting rods 34 in the same group are symmetrically arranged on both sides of the threaded rod 31. Each limiting rod 34 is simultaneously slidably connected to the two positioning side plates 21, and each limiting rod 34 is simultaneously connected to the adjacent end of the two dragging side plates 11. The limiting rods 34 not only ensure the smooth movement of the positioning side plates 21, but also enhance the structural stability of the connection between the dragging side plates 11 and the positioning side plates 21.

[0039] In addition, a second clamping plate 35 is connected to one end of the positioning side plate 21 near the connecting folding plate 13. The second clamping plate 35 and the inner side of the first clamping plate 12 are provided with threaded holes of the same size that match the first bolt 33. After clamping the pipe body 16, the first bolt 33 is removed, and the first clamping plates 12 and the second clamping plates 35 on both sides are connected respectively. This step can effectively improve the stability of the connection between the dragging side plate 11 and the positioning side plate 21, thereby ensuring the clamping and fixing effect of the pipe body 16 during dragging.

[0040] The working principle of this embodiment is as follows: When using the horizontal directional drilling pipe dragging connection device, firstly, the wall of the pipe body 16 is placed between the dragging side plate 11 and the positioning side plate 21. Then, the operator holds the handwheel 32 and starts to rotate it. The rotation of the handwheel 32 will drive the threaded rod 31 to rotate synchronously. Since the threaded rod 31 is threadedly connected to both the dragging side plate 11 and the positioning side plate 21, when the threaded rod 31 rotates, it will drive the two positioning side plates 21 to gradually move away from each other.

[0041] As the positioning side plate 21 moves, the clamping inner plate 22 connected to one end of it also moves toward the inner wall of the pipe body 16. When the clamping inner plate 22 and its inner anti-slip pad 24 are tightly fitted with the inner wall of the pipe body 16, double clamping and fixing of the inner wall of the pipe body 16 is achieved. At this time, the dragging side plate 11 and the clamping inner plate 22 also complete the clamping of both ends of the pipe body 16 wall.

[0042] After the same set of positioning side plates 21 and dragging side plates 11 clamp and fix the pipe body 16 wall, take the first bolt 33 and connect the first clamping plate 12 and the second clamping plate 35 on both sides respectively. This step can effectively improve the stability of the connection between the dragging side plate 11 and the positioning side plate 21, thereby ensuring the clamping and fixing effect of the pipe body 16 during the dragging process.

[0043] After both sets of dragging side plates 11 have clamped and fixed the pipe body 16, place the two mounting horizontal plates 25 on the side of the dragging side plates 11 away from the pipe body 16, and then use the second bolts 26 to connect each mounting horizontal plate 25 to the two dragging side plates 11 on one side at the same time. The function of the mounting horizontal plates 25 is to protect both ends of the pipe body 16 during the dragging process.

[0044] Throughout the operation, each limiting rod 34 is simultaneously slidably connected to two positioning side plates 21, allowing the positioning side plates 21 to move around the limiting rod 34 as an axis. The main function of the positioning side plates 21 is to drive the clamping inner plate 22 to move, thereby clamping and fixing the inner wall of the pipe body 16. The limiting side plate 23 is set to limit the length of the positioning side plate 21 inserted into the pipe body 16. The connecting folding plate 13 connects the connecting end plate 14 to the first clamping plate 12, while the cable sleeve 15 is there to facilitate the passage of ropes for subsequent dragging operations of the pipe body 16.

[0045] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
