Abstract
Description
Technical Field
[0001] This utility model relates to the field of power pole technology, specifically an assembled power pole with a built-in alignment structure. Background Technology
[0002] Currently, the segmented connection of assembled power poles mainly uses flange bolt fixing. This method has a fundamental shortcoming: before tightening the bolts, there is a lack of physical positioning constraints between the upper and lower pole segments, leading to two key problems:
[0003] Free-floating state: Before the bolts are inserted, the pole segments are only suspended by the crane to maintain their relative position. Affected by wind and boom sway, the pole body is prone to radial slippage and angular deflection, which is not conducive to stable assembly.
[0004] Forced correction of losses: Workers need to forcibly drag the pole section at high altitude to align the flange bolt holes. This process generates residual assembly stress, which can easily lead to plastic deformation of the bolts. In addition, when the flange holes are misaligned, some bolts cannot be evenly stressed, resulting in local overload of preload, which affects the service life of the flange. Furthermore, bolts tightened in a non-precise alignment state will generate periodic shear force under wind vibration load, resulting in low stability after the power pole is assembled.
[0005] To address these issues, we provide an assembled power pole with a built-in alignment structure. Utility Model Content
[0006] The purpose of this invention is to provide an assembled power pole with a built-in alignment structure to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An assembled power pole with a built-in alignment structure includes multiple vertically distributed pole bodies assembled together, with a first flange and a second flange fixed at the top and bottom of each pole body, respectively.
[0009] The rod body is provided with an alignment structure, and adjacent rod bodies are aligned and engaged through the alignment structure. The alignment structure includes:
[0010] A conical recessed groove located in the central area of the first flange and opened at the top of the rod;
[0011] A positioning cone that is fixed to the bottom of the rod and nested coaxially with the conical recessed groove;
[0012] A spring locking structure is provided between the conical recess and the positioning cone to prevent the positioning cone from axially loosening after the conical recess and the positioning cone are coaxially nested.
[0013] As described above, an assembled power pole with a built-in alignment structure has the first flange and the second flange of the same specification, so that the first flange on one pole body and the second flange on the adjacent pole body can be locked together by bolts.
[0014] As described above, an assembled power pole with a built-in alignment structure is provided: the inner contour dimension of the conical recess is adapted to the outer contour dimension of the positioning cone, and the positioning cone is embedded and snapped into the conical recess, with the axis of both on the same straight line.
[0015] An assembled power pole with a built-in alignment structure as described above: The spring locking structure includes an annular groove on a positioning cone and a limiting slot on the inner wall of a conical recess. A wedge block is movably engaged inside the limiting slot. A telescopic rod is connected between the wedge block and the inner wall of the limiting slot. A spring is provided inside the limiting slot and sleeved on the outer circumference of the telescopic rod. When the positioning cone and the conical recess are nested and engaged, one end of the wedge block is driven by the spring force of the spring to move and engage inside the annular groove.
[0016] An assembled power pole with a built-in alignment structure as described above: the number of the limiting slots is set to multiple, and the multiple limiting slots are arranged at equal circumferential intervals on the inner wall of the conical recessed groove.
[0017] As described above, an assembled power pole with a built-in alignment structure has a wedge block with one end facing the positioning cone as an inclined surface. The inclination angle of the inclined surface matches the outer diameter profile of the positioning cone, which facilitates the smooth insertion of the positioning cone into the conical recessed groove and compresses the wedge block.
[0018] An assembled power pole with a built-in alignment structure as described above: the bottom end of the bottom section of the power pole integrally extends to form a grounding weld foot, which is used to fix and weld the bottom end of the entire power pole to the foundation.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing an alignment structure on the rod body, the alignment structure includes a conical recessed groove and a positioning cone. When assembling and installing adjacent rod bodies, the positioning cone is first coaxially embedded into the conical recessed groove to achieve quick blind insertion and alignment between the conical recessed groove and the positioning cone, so that the adjacent rod bodies can be quickly positioned coaxially. A spring locking structure is provided between the conical recessed groove and the positioning cone. After the conical recessed groove and the positioning cone are aligned and locked, the positioning cone is automatically axially locked so that the positioning cone will not axially loosen from the conical recessed groove.
[0020] Therefore, this utility model enables the coaxial positioning and preliminary pre-tightening and locking of adjacent rods by means of an alignment structure before bolting between adjacent rods using the first flange and the second flange. This reduces radial slippage and angular deflection between adjacent rods during the assembly and installation of the rods using the first flange and the second flange, facilitates the alignment of the bolt holes of the first flange and the second flange, makes the connection between the first flange and the second flange more secure, and makes the rods more stable after assembly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Please see Figures 1-6 As an embodiment of this utility model, an assembled power pole with a built-in alignment structure includes multiple vertically distributed pole bodies 1 assembled together, with a first flange 2 and a second flange 3 fixed at the top and bottom of each pole body 1 respectively.
[0030] An alignment structure is provided on rod 1, and adjacent rods 1 are aligned and engaged through the alignment structure. The alignment structure includes:
[0031] A conical recessed groove 4 located in the central region of the first flange 2 and opened at the top of the rod 1;
[0032] A positioning cone 5, which is fixed to the bottom of the rod 1 and coaxially nested with the conical recess 4;
[0033] A spring locking structure is provided between the conical recess 4 and the positioning cone 5 to prevent the positioning cone 5 from axially loosening after the conical recess 4 and the positioning cone 5 are coaxially nested.
[0034] In this embodiment, during use, an alignment structure is provided on the rod 1. The alignment structure includes a conical recessed groove 4 and a positioning cone 5. When assembling and installing adjacent rods 1, the positioning cone 5 is first coaxially embedded into the conical recessed groove 4 to achieve quick blind insertion and alignment between the conical recessed groove 4 and the positioning cone 5, so that the adjacent rods 1 can be quickly positioned coaxially. A spring locking structure is provided between the conical recessed groove 4 and the positioning cone 5. After the conical recessed groove 4 and the positioning cone 5 are aligned and locked, the positioning cone 5 is automatically axially locked so that the positioning cone 5 will not be axially loosened from the conical recessed groove 4. Finally, the adjacent rods 1 are bolted together by the first flange 2 and the second flange 3 to achieve assembly and installation between the adjacent rods 1.
[0035] As a further embodiment of this utility model, the first flange 2 and the second flange 3 adopt the same specification, so that the first flange 2 on one rod 1 and the second flange 3 on the adjacent rod 1 can be locked together by bolts.
[0036] In this embodiment, the first flange 2 on a rod 1 and the second flange 3 on an adjacent rod 1 are aligned with their corresponding bolt holes and then joined together. The first flange 2 and the second flange 3 are bolted together by bolts in the bolt holes.
[0037] As a further embodiment of this utility model, the inner contour dimensions of the conical recess 4 are adapted to the outer contour dimensions of the positioning cone 5, and the positioning cone 5 is embedded and snapped into the conical recess 4, and the axis lines of the two are on the same straight line.
[0038] In this embodiment, the inner contour dimensions of the conical recess 4 are adapted to the outer contour dimensions of the positioning cone 5, which facilitates the automatic fit of the positioning cone 5 with the inner wall of the conical recess 4 after it is inserted into the second flange 3, thereby automatically correcting its position. After the positioning cone 5 is embedded and snapped into the conical recess 4, the axis lines of the two are aligned on the same straight line, achieving coaxial positioning. The bottom diameter of the positioning cone 5 is small, and the top diameter of the conical recess 4 is large, which facilitates the quick blind insertion of the positioning cone 5 into the conical recess 4.
[0039] As a further embodiment of this utility model, the spring locking structure includes an annular groove 6 formed on the positioning cone 5 and a limiting groove 8 formed on the inner wall of the conical recess 4. A wedge block 7 is movably engaged inside the limiting groove 8. A telescopic rod 9 is connected between the wedge block 7 and the inner wall of the limiting groove 8. A spring 10 is sleeved on the outer periphery of the telescopic rod 9 inside the limiting groove 8. When the positioning cone 5 and the conical recess 4 are nested and engaged in place, one end of the wedge block 7 is driven by the spring force of the spring 10 to move and engage inside the annular groove 6.
[0040] In this embodiment, the positioning cone 5 moves vertically downward and embeds itself into the conical recess 4. When the positioning cone 5 and the conical recess 4 are nested and engaged, the positioning cone 5 will press the wedge block 7 as it moves downward against the inner wall of the conical recess 4. When the wedge block 7 reaches the same horizontal plane as the annular groove 6, the positioning cone 5 will no longer press the wedge block 7. One end of the wedge block 7 will be driven by the spring force of the spring 10 to move to one side of the positioning cone 5 and be embedded into the annular groove 6 to axially lock the positioning cone 5, so that the positioning cone 5 will not axially loosen, ensuring the stability of the conical recess 4 and the positioning cone 5 after being positioned and engaged.
[0041] As a further embodiment of this utility model, the number of limiting slots 8 is set to multiple, and the multiple limiting slots 8 are arranged at equal circumferential intervals on the inner wall of the conical recessed groove 4.
[0042] In this embodiment, multiple limiting slots 8 are arranged at equal circumferential intervals on the inner wall of the conical recessed groove 4. A wedge block 7 is movably engaged in the limiting slot 8, thereby locking the positioning cone 5 in multiple angular directions through the multiple wedge blocks 7, ensuring the uniformity of the circumferential force on the positioning cone 5 and improving the locking effect on the positioning cone 5.
[0043] As a further embodiment of this utility model, the end face of the wedge block 7 facing the positioning cone 5 is an inclined surface, and the inclination angle of the inclined surface is adapted to the outer diameter profile of the positioning cone 5, so that the positioning cone 5 can be smoothly inserted into the conical recessed groove 4 and compress the wedge block 7.
[0044] In this embodiment, when the positioning cone 5 moves downward in the conical recess 4, it will be in close contact with the inner wall of the conical recess 4, and the outer contour of the positioning cone 5 will be in contact with the inclined surface of the wedge block 7, which facilitates the smooth extrusion and compression of the wedge block 7.
[0045] As a further embodiment of this utility model, the bottom end of the pole section 1 located at the bottom of the power pole is integrally extended to form a grounding weld foot, which is used to fix and weld the bottom end of the entire power pole to the foundation.
[0046] In this embodiment, the bottom end of the lowest section 1 of the power pole extends integrally to form a grounding weld foot, which facilitates the fixing and welding of the entire power pole to the foundation through the lowest section 1.
[0047] In use, the bottom section 1 of the power pole is first fixed to the foundation. Then, multiple sections 1 are hoisted and assembled sequentially with the top of the fixed section 1. The pole 1 has an alignment structure, including a conical groove 4 and a positioning cone 5. When assembling adjacent sections 1, the positioning cone 5 at the bottom of one section 1 is coaxially inserted into the conical groove 4 at the top of the other section 1, achieving quick blind insertion and alignment between the conical groove 4 and the positioning cone 5. This allows for rapid coaxial positioning between adjacent rods 1. A spring locking structure is installed between the conical recess 4 and the positioning cone 5. After the conical recess 4 and the positioning cone 5 are aligned and engaged, the positioning cone 5 is automatically axially locked, preventing it from axially loosening from the conical recess 4. Finally, the adjacent rods 1 are bolted together using the first flange 2 and the second flange 3 to assemble and install them. The above steps are repeated until all rods 1 are vertically assembled and installed.
[0048] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
