Description

Technical Field

[0001] This utility model belongs to the field of crossarm technology, and in particular relates to a crossarm suspension point structure for power transmission tower conductors. Background Technology

[0002] The crossarm of a power transmission tower is a horizontally extending support structure at the top of the tower. It is mainly responsible for the installation and fixing of conductors, lightning protection wires, and insulator strings to ensure that the line maintains stability and a safe distance during operation.

[0003] Currently, when installing cables, crossarms are mostly clamped and pressed in a fixed position. However, cables in high-altitude areas are easily affected by wind, which can cause the installation structure to loosen and affect the normal use of the cables.

[0004] To address the aforementioned issues, this application proposes a crossarm suspension point structure for power transmission tower conductors. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for the crossarm suspension point of a power transmission tower conductor, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a crossarm suspension point structure for power transmission tower conductors, including a crossarm;

[0008] A fixed base is installed above the crossarm, with extension frames fixedly installed at both ends. The adjacent extension frames form a drooping section in the middle of the cable. The fixed base is provided with a limiting clamp inside to further clamp the cable.

[0009] The buffer section is located on the left and right sides of the front and rear ends of the limit clamp, with one end rotatably mounted on the inside of the fixed base.

[0010] Furthermore, the extension frame is equipped with a pressing part via an outer bearing, and the pressing structure at its end is located inside the extension frame.

[0011] Furthermore, the lower end of the limiting clamp is fixedly equipped with a rotating shaft that is rotatably connected to the crossarm.

[0012] Furthermore, the other end of the buffer section is provided with a locking part, located above the two side plates of the limiting clamp.

[0013] Furthermore, a fixing frame is provided below the locking part, and its bottom horizontal plate is located below the two side plates of the limiting clamp, which are combined with the horizontal plate of the locking part to form a clamp.

[0014] Furthermore, a downwardly extending support rod is installed on the outer side of the locking part, which is inserted into the stepped shaft on the outer side of the fixing frame.

[0015] Furthermore, a ring sleeve is fixedly installed at the end of the buffer section and rotatably connected to the stepped shaft.

[0016] This utility model has the following beneficial effects:

[0017] This utility model, by adding a fixing base and combining it with the double-sided clamping method of the extension brackets at both ends, forms a double-area fixation. Thus, when the cable is affected by wind and swayes, the cable in the inner area of ​​the fixing base forms an isolation, so as to prevent the swaying from directly affecting the other section of the cable, making the cable installation more stable.

[0018] This utility model utilizes a built-in buffer section. When the cable in the middle section sways, the internal force is transmitted to both ends and enters the interior of the fixed seat, causing the limiting clamp to swing. At this time, the buffer section buffers and counteracts the force of the cable's swaying, preventing it from being transmitted further, thereby ensuring the stability of the cable when used on the crossarm.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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. 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.

[0029] 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.

[0030] Please see Figure 1-4 As shown, this utility model is a crossarm suspension point structure for a power transmission tower conductor, including a crossarm 1;

[0031] The fixing seat 21 is installed above the crossarm 1, and extension brackets 22 are fixedly installed at both ends. The cable between the adjacent extension brackets 22 sags to a certain extent because the two ends are fixed. Therefore, the tensile force at the two ends is relatively low compared to the cable at the two ends. The fixing seat 21 is provided with a limiting clamp 23 to further clamp the cable. Even if the fixing at the two ends becomes loose, the missing fixing force can be compensated by this structure.

[0032] The buffer section 24 is located on the left and right sides of the front and rear ends of the limiting clamp 23. One end is rotatably installed on the inside of the fixed base 21. When the cable swings, its force is transmitted to the middle drooping section, thereby buffering and offsetting it in this area, preventing it from continuing to be transmitted, and avoiding mutual influence between different sections of the cable.

[0033] The extension frame 22 is equipped with a compression part 221 through the outer shaft seat. The compression structure at the end of the compression part is located inside the extension frame 22, thereby forming a tight fixation on both sides of the cable, forming a single-area dual-point fixation method.

[0034] The lower end of the limiting clamp 23 is fixedly installed with a rotating shaft 231 that is rotatably connected to the crossarm 1. When the swaying force of the cable is transmitted to the middle drooping section, the swaying of the rotating shaft 231 is used to generate lateral swaying, thereby buffering and offsetting the swaying force in conjunction with the buffer part 24.

[0035] The other end of the buffer part 24 is provided with a locking part 25, which is located above the two side plates of the limiting clamp 23. A fixing frame 251 is provided below the locking part 25. Its bottom horizontal plate is located below the two side plates of the limiting clamp 23 and is combined with the horizontal plate of the locking part 25 to form a clamp. An upwardly extending support rod is fixedly installed on the inner side of the fixing frame 241, which slides through the two side plates and connects to the inside of the locking part 25.

[0036] The locking part 25 has a downwardly extending support rod installed on its outer side, which is inserted into the stepped shaft 252 on the outer side of the fixing frame 251. The end of the buffer part 24 is fixedly installed with a ring 241, which is rotatably connected to the stepped shaft 252. The vertical plate extending downward on the outer side of the locking part 25 presses against the upper end face of the ring 241 to form a clamping fixation. Finally, the locking part 25 is connected and fixed to the vertical plate of the fixing frame 251 by bolts.

[0037] It is understood that this utility model can form a segmented fixing effect on the cable and create an isolation zone in the middle section. This can not only compensate for the loose fixing force at both ends, but also buffer and cancel the swaying force of the cable in this area, thereby avoiding mutual interference between different cable segments.

[0038] A specific application of the operation process of this embodiment is as follows: In use, the cable is first threaded through the inside of the two extension frames 22, and then the upper and lower parts of the limiting clamp 23 are merged to form a clamp. Then, the locking part 25 is merged to the top of the fixing frame 251, so that the support rod extending downward from the outside of the locking part 25 is inserted into the inside of the stepped shaft 252. Thus, the ring 241 is rotated and installed between the locking part 25 and the fixing frame 251, and the upper and lower parts of the limiting clamp 23 are locked in place. Furthermore, when the cable sways due to wind, its force is transmitted along the cable to the part inside the fixing seat 21. At this time, the limiting clamp 23 is swayed by the rotational connection between the rotating shaft 231 and the crossarm 1. Combined with the buffering effect of the buffer part 24, the swaying force is canceled out, so that it cannot continue to be transmitted. This can reduce the impact of wind on the cable and prevent the swaying force transmission range from being too large, which would affect the stability of the cable installation structure.
