Technical Field

[0001] This utility model relates to the field of concrete pipe connection technology, and in particular to an axis adjustment device for concrete pipe connection. Background Technology

[0002] Concrete pipes come in various specifications and types, including socket joint pipes, tongue and groove joint pipes, and flat joint pipes. Flat joint pipes, with a flat end, require sealing materials and fasteners to connect the two pipes during subsequent connection. They offer advantages such as simple construction and low cost, making them suitable for applications with less stringent connection requirements, such as temporary drainage pipes. However, aligning the axis of flat joint pipes is relatively difficult. Current methods typically involve crane lifting and manual adjustment, with lifting ropes wrapped around the pipe. During subsequent connection, the ropes can become trapped under the pipe, making removal difficult. Furthermore, manual alignment is labor-intensive and inefficient.

[0003] Therefore, we propose an axis adjustment device for concrete pipe connections to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Reference Figure 1 - Figure 7 The axial adjustment device for connecting concrete pipes includes a crossbeam 1. Several semi-circular frames 2 are equidistantly arranged and fixed on the crossbeam 1. Arc-shaped rods 3 are fitted on both sides of each semi-circular frame 2. Each semi-circular frame 2 has a fixing mechanism that matches the arc-shaped rods 3. A docking positioning mechanism is also fitted to the side of each semi-circular frame 2. The crossbeam 1 and the corresponding semi-circular frames 2 and arc-shaped rods 3 are used to fit onto the concrete pipe body 18.

[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, two or more semi-circular frames 2 can be set on the crossbeam 1.

[0028] For the above example, those skilled in the art should know that when implementing the above technical solution, the dimensions of the crossbeam 1 and the corresponding semi-circular frame 2 and arc rod 3 can be set in various ways to match the concrete pipe body 18 of various dimensions.

[0029] As a technical optimization of this utility model, two collars 4 are symmetrically installed on the top of the crossbeam 1, and the collars 4 can be connected to ropes.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, the collar 4, i.e. the existing heart-shaped collar, can be connected to the rope or hooked to the hook, and the rope can be connected to the existing crane's sling.

[0031] As a technical optimization of this utility model, the outer ring of the semi-circular frame 2 is fixedly connected to the bottom of the crossbeam 1. Slide grooves 5 are provided on both sides of the semi-circular frame 2. Two arc-shaped rods 3 are respectively engaged and slidably matched with the two slide grooves 5. The thickness of the arc-shaped rods 3 is the same as the thickness of the semi-circular frame 2, and a handle 17 is fixed to one end of each arc-shaped rod 3. The handle 17 allows the arc-shaped rod 3 to slide within the slide grooves 5, thus adjusting its position on the semi-circular frame 2. Because the thickness of the arc-shaped rod 3 is the same as the thickness of the semi-circular frame 2, when the semi-circular frame 2 and the arc-shaped rods 3 are installed on the concrete pipe body 18, the inner sides of both the semi-circular frame 2 and the arc-shaped rods 3 can fit snugly against the outer wall of the concrete pipe body 18.

[0032] As a technical optimization of this utility model, the fixing mechanism includes a bolt, which includes a screw 6. One end of the screw 6 is coaxially fixed with a smooth rod 7. The outer diameter of the smooth rod 7 is smaller than the outer diameter of the screw 6. Two insertion hole mechanisms are provided on both sides of the semi-annular frame 2. Each pair of insertion hole mechanisms corresponds to the two ends of the arc-shaped rod 3. The insertion hole mechanism includes a threaded hole 8 provided on one side of the semi-annular frame 2 and a through hole 9 provided on the other side. The threaded hole 8 and the through hole 9 are coaxially corresponding.

[0033] As a technical optimization of this utility model, the screw 6 can be threaded and matched with the threaded hole 8, the smooth rod 7 can be inserted and matched with the through hole 9, and both ends of the arc-shaped rod 3 are provided with transverse circular holes 10 that are matched with the smooth rod 7. After the arc-shaped rod 3 is moved and adjusted, it is necessary to ensure that the circular holes 10 are aligned and matched with the through holes 9. At this time, the smooth rod 7 can be inserted into one end, the smooth rod 7 passes through the circular hole 10 and can be inserted into the corresponding through hole 9, and then the screw 6 is screwed into the threaded hole 8 to lock it, thus achieving a stable fixing effect on the arc-shaped rod 3. The circular holes 10 at both ends of the arc-shaped rod 3 allow for adjustment and positioning fixation in two positions.

[0034] As a technical optimization of this utility model, a base 11 is fixedly provided on the outer side of the middle part of the arc-shaped rod 3, and a cavity 12 corresponding to the base 11 is provided on the inner side of the arc-shaped rod 3. A pressing threaded rod 13 is provided on the base 11, and a pressing block 14 is coaxially fixed to the pressing threaded rod 13 through the base 11. The pressing block 14 is located inside the cavity 12. When the arc-shaped rod 3 is fitted onto the outer wall of the concrete pipe body 18, the pressing threaded rod 13 can be turned to make the corresponding pressing block 14 abut against the outer wall of the concrete pipe body 18.

[0035] As a technical optimization of this utility model, the docking positioning mechanism includes connecting seats 15. Two connecting seats 15 are symmetrically arranged on both sides of the semi-circular frame 2. Two connecting seats 15 located on the same side are detachably and fixedly connected to an arc-shaped positioning plate 16. The arc-shaped positioning plate 16 can fit against the outer wall of the concrete pipe body 18, and the arc-shaped positioning plate 16 corresponds to the port of the concrete pipe body 18. When docking the concrete pipe bodies 18, when the two concrete pipe bodies 18 are aligned end to end, the arc-shaped positioning plate 16 located at the port can fit against the top of the docking port of the two concrete pipe bodies 18, thereby correcting and aligning the ports of the two concrete pipe bodies 18.

[0036] For the above example, those skilled in the art should know that when implementing the above technical solution, the size specifications of the arc-shaped positioning plate 16 can be set in various ways to match the concrete pipe body 18 of various sizes.

[0037] In this invention, the working principle of the device is as follows:

[0038] First, the device is installed on the concrete pipe body 18, with the concrete pipe body 18 positioned horizontally. The crossbeam 1 is placed on top of the concrete pipe body 18. The inner sides of several semi-circular frames 2 and arc-shaped rods 3 are all fitted against the outer wall of the concrete pipe body 18. Then, the arc-shaped rods 3 are pushed by the handle 17, causing them to slide within the groove 5, thus adjusting their position on the semi-circular frames 2. Finally, the several arc-shaped rods 3 are arranged to surround and surround the concrete pipe body 18. Figure 7As shown. Then, the loop 4 on the crossbeam 1 can be fixedly connected to the rope. The rope is then connected to the existing crane's sling, and the crossbeam 1, along with the concrete pipe body 18, can be lifted by the crane for subsequent docking operations. During the docking operation of the concrete pipe body 18, the hoisted concrete pipe body 18 is aligned end-to-end with the previously set concrete pipe body 18. When the two concrete pipe bodies 18 are docked end-to-end, the arc-shaped positioning plate 16 at the port can fit against the top of the docking port of the two concrete pipe bodies 18. As the hoisting moves downward, the arc-shaped positioning plate 16 can correct and align the ports of the two concrete pipe bodies 18, ultimately achieving axis alignment adjustment and ensuring that the axes of the two concrete pipe bodies 18 are aligned, resulting in high overall work efficiency.

[0039] In the above operation, after the axis alignment adjustment is completed, several arc rods 3 can be reset, and the crossbeam 1 and the overall device on it can be easily hoisted away from the concrete pipe body 18.

[0040] Meanwhile, after the arc rod 3 is moved and adjusted, it is necessary to ensure that the round hole 10 is aligned and matched with the through hole 9. At this time, the smooth rod 7 can be inserted into one end, the smooth rod 7 passes through the round hole 10 and can be inserted into the corresponding through hole 9, and then the screw 6 is screwed into the threaded hole 8 to lock it, thus achieving a stable fixing effect on the arc rod 3. The round holes 10 at both ends of the arc rod 3 allow it to be adjusted and fixed in two positions.

[0041] Furthermore, in the above operation, after several arc-shaped rods 3 are surrounded and set on the concrete pipe body 18, the corresponding extrusion blocks 14 can be made to abut against the outer wall of the concrete pipe body 18 by twisting the corresponding extrusion threaded rods 13, thereby enabling the two symmetrical arc-shaped rods 3 to effectively squeeze and clamp the concrete pipe body 18 between them, effectively ensuring the stability of subsequent hoisting and docking operations.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
