Composite insulator cross arm

Abstract

This utility model discloses a composite insulated crossarm, including a pole with an insulated connector sleeved on the top. Mounting plates are screwed to both sides of the insulated connector. An insulating rod is connected to one side of the mounting plate via a connecting mechanism. An adjustment mechanism is located below one side of the mounting plate, and a positioning mechanism is sleeved on the outside of the adjustment mechanism. The positioning mechanism is connected to the bottom of the insulating rod via the mounting mechanism. Driving mechanisms are symmetrically arranged on both sides of the positioning mechanism, and each driving mechanism contacts one side of the insulating rod. The adjustment mechanism includes a concave plate and an adjustment shaft. Through the cooperation of multiple structures such as the connecting mechanism, adjustment mechanism, positioning mechanism, mounting mechanism, and driving mechanism, the load is distributed: multiple support structures can disperse the conductor tension and wind load borne by the crossarm to more locations on the utility pole, reducing local stress concentration and preventing overloading of the crossarm or main clamp.

Description

Technical Field

[0001] This utility model relates to the field of crossarm auxiliary equipment technology, specifically to a composite insulated crossarm. Background Technology

[0002] Crossarms are an important component of towers. Their function is to install insulators and fittings to support conductors and lightning protection wires and to maintain a certain safe distance between them as required.

[0003] For example, an existing Chinese authorized patent (publication number: CN222184327U) discloses a composite insulating crossarm, including a utility pole and an insulating rod. Both ends of the insulating rod are provided with connecting blocks for connecting to electrical wires, and the insulating rod is provided with a connecting assembly for fixing to the utility pole. The connecting assembly includes an insulating plate and a fixing ring. The fixing ring is provided with a buffer assembly for buffering stress transmitted to the utility pole. The buffer assembly includes an elastic block and an elastic ring, and the fixing ring is provided with a buffer part for buffering stress on the elastic block. The buffer part includes a fixing seat, an extension rod, and a return spring. This invention, through the design of the elastic block, elastic ring, and return spring, can disperse and buffer the stress at the connection point in multiple directions, improving the buffering effect against force, maintaining the stability of the insulating rod and insulating plate, and preventing them from shaking under external impact, which could cause the connected wires to shake and potentially detach, posing a safety hazard.

[0004] The composite insulated crossarms designed as described above have the following disadvantages in actual use: they are mostly fixed to the upper end of the utility pole by U-shaped clamps, which have limited load-bearing capacity. Metal fatigue of the U-shaped clamps may cause deformation or breakage, leading to the crossarm sinking.

[0005] In view of this, a composite insulating crossarm is provided to overcome the above-mentioned defects. Utility Model Content

[0030] In this embodiment, the insulating rod 5 is first installed on the mounting plate 3 by the connecting mechanism 4. Next, the positioning mechanism 7 sleeved on the outside of the adjusting mechanism 7 is adjusted. One side of the positioning mechanism 7 contacts the bottom of the insulating rod 5 and is connected by the mounting mechanism 8. The positioning mechanism 7 supports the insulating rod 5. Then, the components in the driving mechanism 9 are adjusted and fitted to one side of the insulating rod 5. The fitting point is connected by bolts.

[0031] Example 2

[0032] The connecting mechanism 4 includes a connecting plate 10, connecting holes 11, and connecting bolts 12. The connecting plate 10 is disposed on one side of the mounting plate 3. Multiple connecting holes 11 are drilled on one side of the connecting plate 10, the mounting plate 3, and the insulating connector 2. Connecting bolts 12 are threadedly connected between the connecting holes 11. The connecting plate 10, the mounting plate 3, and the insulating rod 5 are attached to each other, and the connecting holes 11 on them are aligned. The connecting bolts 13 are threadedly inserted into the aligned connecting holes 11. The insulating rod 5 is mounted on the mounting plate 3.

[0033] The adjustment mechanism 6 includes a concave plate 13 and an adjustment shaft 14. The concave plate 13 is disposed on one side of the mounting plate 3, and the adjustment shaft 14 is disposed on the inner wall of the concave plate 13.

The positioning rod 15 is sleeved on the outer wall of the adjusting shaft 14, and the positioning plate 16 is fixedly connected to one side of the top surface of the positioning rod 15. The positioning rod 15 sleeved on the adjusting shaft 14 is adjusted with the components on it. The positioning plate 16 on the positioning rod 15 contacts the bottom of the insulating rod 5, and the mounting hole 17 on it is connected. The mounting bolt 18 is inserted into the connected mounting hole 17 through the thread to support the insulating rod 5.

[0035] The mounting mechanism 8 includes mounting holes 17 and mounting bolts 18. The mounting holes 17 are respectively dug at the bottom of the positioning plate 16 and the bottom of the insulating rod 5. The mounting holes 17 are connected by mounting bolts 18 through threads.

[0036] The driving mechanism 9 includes a sleeve 19, a return spring 20, a driving rod 21, a support plate 22, driving holes 23, and driving bolts 24. The sleeve 19 is symmetrically arranged on the front and rear sides of the positioning rod 15. The return spring 20 is provided on the top of the sleeve 19. The driving rod 21 is provided on one side of the return spring 20. The support plate 22 is provided on one side of the driving rod 21. Multiple driving holes 23 are drilled on both the support plate 22 and one side of the insulating rod 5. The driving holes 23 are connected by threads to the driving bolts 24. Pulling the driving rod 21 transmits the pulling force to the return spring 20, causing the return spring 20 to deform and adjust the driving rod 21 and its components. Under the drive of the driving rod 21, the support plate 22 on it fits against one side of the insulating rod 5. The driving holes 23 are aligned at the fit point. The driving bolts 24 are inserted into the aligned driving holes 23 by threads.

[0037] Based on Example 1, the structure and function of the device are further optimized. Bird spikes can be installed on multiple components. Birds like to nest on electrical facilities such as crossarms and insulators. Nesting materials (such as branches and wires) may fall or cause short circuits. Bird spikes can effectively prevent birds from landing, reducing the risk of nesting. Bird droppings can contaminate insulators, reducing their insulation performance, especially in humid environments, which can easily lead to flashover accidents. Bird spikes reduce bird landings, thereby reducing the accumulation of bird droppings. Bird pecking or scratching can damage cables, insulation layers, and other equipment. Bird spikes provide physical isolation, extending the life of the equipment.

[0038] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, firstly, the connecting plate 10, the mounting plate 3 and the insulating rod 5 are attached together, and the connecting holes 11 on them are aligned. The connecting bolt 13 is inserted into the aligned connecting hole 11 through the thread. The insulating rod 5 is mounted on the mounting plate 3. Next, the positioning rod 15 sleeved on the adjusting shaft 14 is adjusted with the components on it. The positioning plate 16 on the positioning rod 15 contacts the bottom of the insulating rod 5, and the mounting hole 17 on it is aligned. The mounting bolt 18 is inserted into the aligned mounting hole 17 through the thread to support the insulating rod 5. Then, the drive rod 21 is pulled, and the drive rod 21 transmits the pulling force to the return spring 20, causing the return spring 20 to deform and adjust the drive rod 21 with the components on it. Under the drive of the drive rod 21, the support plate 22 on it is attached to one side of the insulating rod 5, and the drive hole 23 at the attachment point is aligned. The drive bolt 24 is inserted into the aligned drive hole 23 through the thread.
