Description

Technical Field

[0001] This utility model belongs to the field of power engineering technology, and in particular relates to a bracket for replacing insulators. Background Technology

[0002] Insulators are critical components in power systems used to isolate live conductors from supporting structures. They block current conduction through insulating materials while simultaneously withstanding mechanical loads, ensuring the safe operation of high-voltage equipment. Their core value can be likened to "insulating gloves on high-voltage power poles," protecting personnel safety and maintaining power grid stability.

[0003] However, in the actual operating environment of power transmission and distribution systems, traditional insulator installation mostly follows the traditional paradigm of rigid fixing. It usually relies on bolts to achieve a tight and relatively fixed assembly state between the insulator and the cable. However, this seemingly stable fixing mode makes it extremely difficult for workers to replace the insulators later, making it difficult to complete the replacement work quickly and efficiently.

[0004] Therefore, there is a particular need for a bracket for replacing insulators to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional rigid fixed installation of insulators, which, although stable on the surface, leads to difficulties in operation and low efficiency during replacement, the technical problem is to provide a bracket for replacing insulators.

[0006] The technical solution of this utility model is as follows: a bracket for replacing insulators, comprising connecting plates, support rods, a frame, a first extension rod, a rotating block, a bidirectional screw, clamping rods, a second extension rod, a torsion spring, and a rotating frame. Two connecting plates are slidably arranged side by side on the frame. Multiple support rods distributed on the same side are grouped into two groups, each group of support rods being fixed to each connecting plate. Each first extension rod is slidably arranged between every two longitudinally aligned support rods. The bidirectional screw is rotatably arranged on the right side of the frame. One side of each of the two connecting plates is threadedly engaged with the bidirectional screw. The rotating block is fixedly connected to one end of the bidirectional screw. Every two rotating frames arranged side by side are rotatably arranged on each connecting plate. Each torsion spring is sleeved on one end of each rotating frame, and its two ends are fixedly connected to the corresponding connecting plate and the corresponding rotating frame, respectively. Every two clamping rods are fixedly arranged on each rotating frame, and the angle between the two clamping rods is an obtuse angle. Each second extension rod is slidably and rotatably arranged between every two longitudinally aligned clamping rods.

[0007] Furthermore, it also includes insulating rubber, with different quantities and sizes of insulating rubber fitted onto the outside of each support rod, each first extension rod, and each clamp rod.

[0008] Furthermore, it also includes guide rods, which are fixed to the left side of the frame, and the other side of the two connecting plates are slidably connected to the guide rods.

[0009] Furthermore, it also includes hooks, with multiple hooks arranged along a rectangular direction and fixed to the top of the frame.

[0010] Furthermore, it also includes strap openings, with multiple strap openings of the same number as the hooks arranged in two rows and two columns, fixed at the top of the frame.

[0011] Furthermore, it also includes anti-slip blocks, with multiple anti-slip blocks arranged in a rectangular array and fixed to the top of the frame.

[0012] Beneficial effects: By setting up adjustable connecting plates and adjustable support rods, it can flexibly adapt to insulators of different lengths. With the help of the clamping mechanism composed of clamping rods, torsion springs and rotating frames, the insulator only needs to be placed between the two connecting plates. Its own weight will trigger the clamping rods to rotate clockwise around the hinge point of the rotating frame, so that the clamping rods originally at the lower position rotate clockwise to the higher position, thus completing the clamping and fixing of the insulator. No additional tools or complicated operations are required, realizing automated and convenient installation, and facilitating quick replacement and simplifying the process later.

[0021] Example: A bracket for replacing insulators, such as Figures 1-7As shown, the insulator includes a connecting plate 1, support rods 2, insulating rubber 3, frame 4, first extension rod 5, rotating block 6, bidirectional screw 7, guide rod 8, clamping rod 9, second extension rod 91, torsion spring 10, rotating frame 11, hook 12, binding strap opening 13, and anti-slip block 14. Two connecting plates 1 are arranged side-by-side and slidably mounted on the frame 4. Four support rods 2 distributed on the same side (i.e., front or rear side) form a group, with two groups in total. Each group of support rods 2 is welded to each connecting plate 1. Each first extension rod 5 is slidably mounted between every two longitudinally aligned support rods 2. Through the four first extension rods 5, a sliding connection is formed between the eight support rods 2 on the front and rear sides, enabling the insulator to adapt to various conditions. The length is extended to effectively support insulators of different lengths. A bidirectional screw 7 is rotatably mounted on the right side of the frame 4. The right sides of both connecting plates 1 are threaded into the bidirectional screw 7. A rotating block 6 is welded to the front end of the bidirectional screw 7, facilitating its rotation. A guide rod 8 is welded to the left side of the frame 4. The left sides of both connecting plates 1 are slidably connected to the guide rod 8, ensuring smooth linear movement of the connecting plates 1. Two rotating frames 11 are rotatably mounted on each connecting plate 1, arranged side-by-side. Each torsion spring 10 is sleeved on the outward-facing end of each rotating frame 11, with its two ends fixedly connected to the corresponding connecting plate 1 and the corresponding rotating frame 11. Two clamping rods 9 are welded to each... On the rotating frame 11, the angle between the two clamping rods 9 is obtuse (i.e., one clamping rod 9 is at a higher position and the other clamping rod 9 is at a lower position). Each second extension rod 91 is slidably and rotatably positioned between every two longitudinally aligned clamping rods 9. Through the four second extension rods 91, a sliding connection is formed between the eight clamping rods 9 on the front and rear sides, which can be extended according to the length of the insulator, thereby effectively clamping insulators of different lengths. Each support rod 2, each first extension rod 5, and each clamping rod 9 are fitted with a different number and size of insulating rubber 3. Specifically, each support rod 2 has four insulating rubber 3s on its outside, and each first extension rod 5 has one insulating rubber 3 on its outside. Each clamp 9 has three insulating rubbers 3 on its exterior. Four hooks 12 are arranged along a rectangular direction and welded to the four corners of the top of the frame 4. The hooks 12 increase the contact points between the frame 4 and the cable. Four strap openings 13, the same number as the hooks 12, are arranged in two rows and two columns and welded to the top of the frame 4. The strap openings 13 provide fixing points for the frame 4 to be fixed to the cable. Four anti-slip blocks 14 made of insulating material are arranged in a rectangular array and adhered to the top of the frame 4. The anti-slip blocks 14 provide a better grip and anti-slip effect when holding the frame 4, ensuring that the staff can use the frame 4 more safely and stably.

[0022] When a bracket is needed, the staff first places the frame 4 stably near the cable and uses the hook 12 to hook the frame 4 onto the cable. Then, the prepared high-strength binding strap is passed through the binding strap opening 13, and the binding strap is wrapped around the cable and tightened. The frame 4 is fixed by a suitable binding method to ensure that the connection between the frame 4 and the cable is firm and reliable.

[0023] After the frame 4 is fixed, hold the rotating block 6 and rotate the double-headed screw 7 clockwise. Driven by the double-headed screw 7, the two connecting plates 1 move inward and get closer to each other until the distance between the two connecting plates 1 is sufficient to place the insulator. Then, place the insulator in the space defined by the two connecting plates 1 (i.e., between the two connecting plates 1) so that its bottom makes good contact with the support rod 2. During this process, the bottom of the insulator contacts the clamping rod 9, which was originally at the higher position, and applies downward pressure. With the help of the insulator's own gravity, this pressure causes the clamping rod 9, which was originally at the higher position, to rotate clockwise around its hinge point with the rotating frame 11. As the clamping rod 9 rotates clockwise, the rotating frame 11 connected to it rotates clockwise synchronously, thereby driving the clamping rod 9, which was originally at the lower position, to rotate clockwise to the higher position, and finally contact the edge of the insulator to achieve clamping. At the same time, the torsion spring 10 undergoes elastic deformation due to the external force, converting mechanical energy into elastic potential energy for storage. Thus, the insulator lifting and installation process is successfully completed.

[0024] When it is necessary to replace the insulator, the worker will carefully remove the original insulator from the support rod 2, so that it is no longer in contact with the clamp rod 9. At this time, the torsion spring 10, which was originally in a deformed and energy-storing state due to the compression of the insulator, will begin to return to its original shape. The elastic restoring force generated in this process will cause the rotating frame 11 to drive the clamp rod 9 to reverse the movement until the clamp rod 9 and the rotating frame 11 return to the initial angle position. After the old insulator is removed, the above installation process is repeated to lift the new insulator, and the insulator replacement operation can be completed.
