[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Example:

[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a crossarm structure for power poles, comprising:

[0035] Cross arm body 1;

[0036] The shock-absorbing component 2 is placed inside the crossarm body 1. The shock-absorbing component 2 includes a hanging point 21 that is slidably connected to the crossarm body 1. A guide rod 29 is slidably connected to the hanging point 21. The guide rod 29 is fixedly connected inside the crossarm body 1. A damping body 23 is fixedly connected to the hanging point 21. A first rubber pad 22 is fixedly connected to the damping body 23. A first fixing rod 24 is fixedly connected to the first rubber pad 22. A second fixing rod 25 is fixedly connected to the first fixing rod 24. A lower slider 27 is fixedly connected to the second fixing rod 25. A transmission rod 28 is fixedly connected to the lower slider 27. A transmission block 26 is slidably connected to the transmission rod 28. A second rubber pad 31 is fixedly connected to the bottom of the transmission block 26.

[0037] Connecting block 3 is fixedly connected to the bottom of crossarm body 1, and connecting block 3 is slidably connected to the second rubber pad 31.

[0038] In this invention, when the cable vibrates due to wind, galloping, or other factors, causing the hanging point 21 to vibrate accordingly, the hanging point 21 first contacts and presses against the first rubber pad 22. The rubber pad, with its high damping characteristics, absorbs and dissipates some of the stress generated by the vibration, providing initial buffering. The sliding of the first rubber pad 22 further displaces the first fixed rod 24 fixed thereon. The first fixed rod 24 moves synchronously with the second fixed rod 25. Then, the second fixed rod 25 causes the lower slider 27 to move. The lower slider 27 drives the transmission rod 28 fixed thereon to slide within the oblique hole on the transmission block 26. Due to the guiding and limiting effect of the oblique hole, the transmission block 26 is driven by the transmission rod 28 to slide on the crossarm body 1, eventually sliding into the insertion connecting block 3. At this point, the second rubber pad 31 on the connecting block 3 is pushed out by the transmission block 26 and comes into close contact with the power pole. The rubber pad absorbs and buffers the vibration energy again, transmitting and converting the cable vibration step by step. The damping characteristics of the rubber pad repeatedly weaken the vibration impact, effectively protecting the crossarm structure of the power pole and the stable operation of the transmission line.

[0039] Further, as shown in Figures 1 to 5 The first rubber pad 22 is slidably connected to the guide rod 29, and is provided with the first rubber pad 22 (model: HDR-CR-80-20) having excellent elastic and damping properties. When vibration occurs, the hanging point 21 is stressed to drive the first rubber pad 22 to slide along the guide rod 29, and the rubber pad can quickly deform to convert part of the vibration energy into heat energy, effectively buffer the initial impact, improve the damping effect, and ensure the stability of the cross arm structure.

[0040] The first rubber pad 22 is provided with an opening, and the guide rod 29 is slidably connected to the opening in the first rubber pad 22. In use, the guide rod 29 fixed to the cross arm body can be tightly embedded in the opening. On the one hand, the guide rod 29 limits the sliding range of the first rubber pad 22, so that it can only move in a specified direction, avoiding deviation to cause uneven energy loss. On the other hand, the close fit between the two ensures that the rubber pad always remains relatively attached to the inner wall of the cross arm body 1 during vibration, allowing the damping effect to be fully and continuously exerted.

[0041] The transmission block 26 is provided with a inclined hole, and the transmission rod 28 is slidably connected to the inclined hole in the transmission block 26. In use, when the lower sliding block 27 is driven by vibration to drive the transmission rod 28 to slide on the connecting block 3, due to the unique inclination angle and limiting effect of the inclined hole, the transmission rod 28 will exert a oblique component force on the transmission block 26, forcing the transmission block 26 to overcome its own friction and stably slide on the cross arm body 1 in a specific direction, accurately transmitting vibration energy and ensuring smooth operation of subsequent damping links.

[0042] The connecting block 3 is provided with an opening, and the transmission block 26 is slidably connected to the opening in the connecting block 3. By reasonably providing the opening in the connecting block 3, the transmission block 26 can freely and smoothly slide in the space defined by the opening when in use. The size of the opening is matched with the transmission block 26, so that it will not hinder the movement of the transmission block 26 due to being too tight, nor will it cause the transmission block 26 to shake due to being too loose, ensuring that the vibration energy can be efficiently transmitted to the connecting block 3 to trigger subsequent damping actions.

[0043] The cross arm body 1 is provided with an opening on both sides, and the first fixed rod 24 is slidably connected to the openings on both sides of the cross arm body 1. In use, the first fixed rod 24 can flexibly slide in the opening, and the opening provides space for the displacement of the first fixed rod 24, so that it can adjust its position in time following the movement of the front end component, ensuring smooth linkage of the entire damping assembly 2 and accurately transmitting vibration from the cable to the bottom of the cross arm body 1 to complete the damping task.

[0044] The above scheme also has the problem of not proposing the installation position of the guide rod 29 on the cross arm body 1, such as Figure 3As shown, the inner wall bottom of the cross arm body 1 is provided with a groove, and the guide rod 29 is fixedly connected in the groove of the inner wall bottom of the cross arm body 1. By providing the groove in the inner wall bottom of the cross arm body 1, the guide rod 29 can be closely embedded in the groove and fixed during use, so that the guide rod 29 is stably installed and is not easy to be loosened and displaced during vibration. Therefore, the first rubber pad 22 can be flatly and closely attached to the inner wall surface of the cross arm body 1 in the initial state, so that the damping effect can be efficiently exerted at the beginning of vibration, and the damping performance of the entire cross arm structure is optimized.

[0045] As shown in the drawings, Figures 1-5 As shown, when the cable is vibrated and the hanging point 21 is vibrated during use, the hanging point 21 first presses the first rubber pad 22 to release part of the stress. In this process, the first rubber pad 22 slides on the guide rod 29, so that the first fixed rod 24 is driven to displace, the second fixed rod 25 is driven to displace, the lower sliding block 27 drives the transmission rod 28 to slide in the inclined hole of the transmission block 26, the transmission block 26 is driven to slide on the cross arm body 1 and is inserted into the connecting block 3, so that the second rubber pad 31 on the connecting block 3 is pushed out and presses the wire pole, thereby achieving further damping effect.

[0046] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and equivalent embodiments with equivalent changes can be obtained. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the scope of the present application.
