Description

Technical Field

[0001] This utility model relates to the technical field of power line tower connection structure, specifically a power line tower connection structure. Background Technology

[0002] The collector tower connection structure disclosed in CN220621309U includes an inner liner, a limiting component, a connecting component, and a fixing component. The inner liner is fitted at the connection of the collector tower, the limiting component is fitted on the outer wall of the inner liner, and the connecting component is fitted on the outer wall of the limiting component. The limiting component is fixedly connected to the connecting component through the fixing component. The limiting component is fixed by screws, and two adjacent connecting components are fixed by screws. Two limiting components and two connecting components are provided along the axial direction of the connection of the collector tower, and they are mirror-distributed along the connection surface.

[0003] By optimizing the structure and using simple fixing methods such as screw connections between components, it saves time and improves installation efficiency, solving the problems of excessive parts, complex structure, time-consuming installation and disassembly, and low work efficiency in existing technologies.

[0004] The technical solution in this prior art document is easy to assemble and disassemble, but the defects are also more obvious. For example, the inner lining is made of rubber, which is susceptible to ultraviolet rays and extreme temperatures when exposed to the outdoor environment for a long time. This may cause the rubber to harden, crack, or lose elasticity, thereby reducing the shockproof and anti-slip performance and affecting the connection stability. The fit between the fixing block and the insertion slot depends on the precise manufacturing tolerance. If there is a gap or vibration environment, the fixing block may gradually loosen, causing displacement between the limiting component and the connecting component, resulting in the connection separation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a connection structure for power line towers. It solves the problem that rubber linings are susceptible to damage from ultraviolet radiation and extreme temperatures when exposed to outdoor environments for extended periods, which can lead to hardening, cracking, or decreased elasticity, thereby reducing shock absorption and anti-slip performance and affecting connection stability. Furthermore, the fit between the fixing block and the insertion slot relies on precise manufacturing tolerances. If gaps or vibrations exist, the fixing block may gradually loosen, causing displacement between the limiting component and the connecting component, resulting in connection separation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power line tower connection structure, including a left frame and a right frame, with the right frame disposed on the side of the left frame, mounting holes symmetrically opened on the sides of the left and right frames and bolts threaded inside the mounting holes, mounting plates sleeved on the surfaces of the left and right frames, connecting holes opened between the mounting plates and the sides of the left and right frames and limiting components threaded inside the connecting holes, and contact components fixedly connected to the sides of the left and right frames;

[0007] The contact assembly includes a soft package fixedly connected to the sides of the left and right frames. The soft package has a cavity inside, and a small spring is fixedly connected to the inner wall of the cavity. A push plate is fixedly connected to the side of the small spring.

[0008] The limiting component includes a locking rod threaded into the connecting hole. One end of the locking rod has a sleeve hole symmetrically formed. A spring is sleeved inside the sleeve hole, and a locking bead is fixedly connected to the side of the spring.

[0009] In one specific embodiment, the inner wall of the connecting hole is provided with a locking hole that fits into the locking bead, and the locking bead is inserted into the locking hole under the elastic force of the spring.

[0010] In one specific embodiment, the soft package is fixed to the sides of the left and right frames by adhesive or welding, and the end face of the push plate contacts the inner sidewall of the mounting plate.

[0011] In one specific embodiment, the soft package is made of a flexible elastic material, and the small springs inside the cavity are distributed in a linear array along the length of the soft package.

[0012] In a specific embodiment, the mounting holes of the left frame and the right frame are symmetrically distributed on both sides of the connecting surface, and the connecting holes of the mounting plate are coaxially arranged with the mounting holes.

[0013] In one specific embodiment, the length of the threaded section of the clamping rod matches the depth of the connecting hole, and the diameter of the clamping bead is smaller than the diameter of the sleeve hole but larger than the diameter of the clamping hole.

[0014] Compared with the prior art, the present invention provides a power line tower connection structure, which has the following advantages:

[0015] In the technical solution disclosed in this utility model, by setting a contact component to replace the rubber liner, the push plate adaptively adjusts the contact pressure through the rebound force of the small spring when it is pressed, avoiding the decline in shockproof and anti-slip performance due to material aging; the limiting component optimizes the defect of easy loosening of the fixing block, and the locking rod forms a double locking of thread fastening and snap-fit, so that it remains locked in a vibrating environment, effectively preventing displacement between the left and right frames and the mounting plate due to tolerance gaps or external forces, and ensuring the stability of the connection structure under dynamic loads.

[0016] The left and right frames are pre-tightened and fixed by bolts in the mounting holes using the contact and limiting components provided in this invention. Then, the mounting plate is fitted onto the outer surfaces of the left and right frames, ensuring that the connecting holes of the mounting plate are coaxially aligned with the mounting holes of the left and right frames. Contact components are fixed to the sides of the left and right frames. The soft package is fixed to the side of the frame by adhesive or welding. A small spring inside its cavity elastically abuts against the inner wall of the mounting plate via a push plate. When the mounting plate is compressed, the push plate adaptively adjusts the contact pressure due to the elastic force of the small spring. The soft, flexible material isolates the internal spring structure from external environmental corrosion, preventing buffer failure caused by material aging. Then, the locking rod of the limiting component is screwed into the connecting hole. The spring in the sleeve hole at the end of the locking rod pushes the locking bead outward. The locking bead is embedded in the locking hole on the inner side wall of the connecting hole to form a locking engagement. The length of the threaded section of the locking rod matches the depth of the connecting hole to ensure both thread fastening and locking engagement to prevent loosening. The design of the locking bead diameter being larger than the locking hole diameter ensures that it remains locked even under vibration, ultimately achieving a stable connection between the left frame, right frame and mounting plate.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4As an embodiment of this utility model, a power line tower connection structure includes a left frame 1 and a right frame 2, characterized in that: the right frame 2 is provided on the side of the left frame 1; the sides of the left frame 1 and the right frame 2 are symmetrically provided with mounting holes and bolts are threaded inside the mounting holes; mounting plates 3 are sleeved on the surfaces of the left frame 1 and the right frame 2; the mounting plates 3 and the sides of the left frame 1 and the right frame 2 are provided with connection holes and limiting components 4 are threaded inside the connection holes; and contact components 5 are fixedly connected to the sides of the left frame 1 and the right frame 2.

[0025] The specific problems addressed in this embodiment are: the inner lining, made of rubber, is susceptible to damage from ultraviolet radiation and extreme temperatures when exposed to outdoor environments for extended periods, potentially leading to hardening, cracking, or decreased elasticity, thus reducing shock absorption and anti-slip performance and affecting connection stability; the fit between the fixing block and the insertion slot relies on precise manufacturing tolerances, and gaps or vibrations can cause the fixing block to gradually loosen, leading to displacement between the limiting component and the connecting component, resulting in connection separation. This invention replaces the rubber inner lining with a contact component 5. When the push plate 53 is compressed, the rebound force of the small spring 52 adaptively adjusts the contact pressure, preventing a decrease in shock absorption and anti-slip performance due to material aging; the limiting component 4 optimizes the fixing block's tendency to loosen, and the locking rod 41 forms a dual locking mechanism of threaded fastening and snap-fit, ensuring it remains locked even under vibration, effectively preventing displacement between the left frame 1 and right frame 2 and the mounting plate 3 due to tolerance gaps or external forces, ensuring the stability of the connection structure under dynamic loads.

[0026] The contact component 5 includes a soft package 51 fixedly connected to the sides of the left frame 1 and the right frame 2. The soft package 51 has a cavity inside, and a small spring 52 is fixedly connected to the inner wall of the cavity. A push plate 53 is fixedly connected to the side of the small spring 52. The limiting component 4 includes a locking rod 41 threadedly connected to the inside of the connecting hole. A sleeve hole is symmetrically opened at one end of the locking rod 41. A spring 42 is sleeved inside the sleeve hole, and a locking bead 43 is fixedly connected to the side of the spring 42. In this specific embodiment, a locking hole that fits with the locking bead 43 is opened on the inner wall of the connecting hole. The locking bead 43 is embedded in the locking hole under the elastic force of the spring 42. The soft package 51 is fixed to the sides of the left frame 1 and the right frame 2 by adhesive or welding. The end face of the push plate 53 contacts the inner wall of the mounting plate 3. The left frame 1 and right frame 2 are pre-tightened and fixed using bolts in the mounting holes. Then, the mounting plate 3 is fitted onto the outer surfaces of the left frame 1 and right frame 2, ensuring the connecting holes of the mounting plate 3 are coaxially aligned with the mounting holes of the left frame 1 and right frame 2. Contact components 5 are fixed to the sides of the left frame 1 and right frame 2. The soft package 51 is fixed to the side of the frame by adhesive or welding. A small spring 52 inside its cavity elastically abuts against the inner wall of the mounting plate 3 via a push plate 53. When the mounting plate 3 is compressed, the push plate 53 adaptively adjusts the contact pressure under the elastic force of the small spring 52. The soft package 51's flexibility and elasticity... The material isolates the internal spring structure from external environmental corrosion, preventing buffer failure caused by material aging. Then, the locking rod 41 of the limiting component 4 is screwed into the connecting hole. The spring 42 in the sleeve hole at the end of the locking rod 41 pushes the locking bead 43 outward. The locking bead 43 is embedded in the locking hole on the inner side wall of the connecting hole to form a locking engagement. The length of the threaded section of the locking rod 41 matches the depth of the connecting hole to ensure both thread fastening and locking engagement to prevent loosening. The design of the locking bead 43 having a diameter larger than the locking hole diameter ensures that it remains locked even under vibration. Finally, a stable connection between the left frame 1, the right frame 2 and the mounting plate 3 is achieved.

[0027] In this specific embodiment, the mounting holes of the left frame 1 and the right frame 2 are symmetrically distributed on both sides of the connecting surface, and the connecting holes of the mounting plate 3 are coaxially arranged with the mounting holes.

[0028] By symmetrically distributing the mounting holes of the left frame 1 and the right frame 2 on both sides of the connecting surface and setting the connecting holes of the mounting plate 3 to be coaxial with the mounting holes, the sleeve direction of the mounting plate 3 during assembly coincides with the axis of the mounting holes of the left frame 1 and the right frame 2. This ensures that the bolts and the locking rods 41 of the limiting component 4 are precisely aligned, avoiding installation misalignment or local stress concentration caused by hole offset. At the same time, the symmetrically distributed mounting holes allow the force on the left frame 1 and the right frame 2 to be evenly transmitted to the mounting plate 3. Combined with the elastic support of the push plate 53 of the contact component 5 for the small spring 52, the impact of installation error on structural stability is further reduced, thereby extending the service life of the connection structure under dynamic load.

[0029] Working principle: The mounting plate 3 is pre-tightened and fixed to the outer surfaces of the left and right frames 1 and 2 via symmetrically distributed mounting holes and bolts. When the mounting plate 3 is fitted onto the outer surfaces of the left and right frames 1 and 2, its connecting holes are coaxially aligned with the mounting holes to ensure precise alignment of the locking rod 41 and bolts of the limiting component 4. The soft package 51 of the contact component 5 pushes the push plate 53 into elastic contact with the inner wall of the mounting plate 3 via a linear array of small springs 52 within the cavity. Under external load, the push plate 53 adaptively adjusts the contact pressure due to the elastic force of the small springs 52. The flexible elastic material isolates the spring structure from the direct erosion of the external environment, avoiding buffer failure caused by material aging; after the locking rod 41 of the limiting component 4 is screwed into the connecting hole, the spring 42 in its sleeve hole pushes the locking bead 43 into the locking hole on the inner side wall of the connecting hole. The diameter of the locking bead 43 is larger than that of the locking hole to form an interference fit. Combined with the thread length of the locking rod 41 and the depth of the connecting hole, the thread fastening and locking are matched to achieve a double locking, ensuring the stable connection of the left frame 1, the right frame 2 and the mounting plate 3 under vibration or temperature difference deformation.
