Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for live-line work, and in particular to an insulated lifting rod for live-line work. Background Technology

[0002] Live-line work refers to a method of maintenance and testing on high-voltage electrical equipment without interrupting power supply. Electrical equipment requires frequent testing, inspection, and maintenance during long-term operation. Live-line work is an effective measure to avoid power outages during maintenance and ensure normal power supply. The content of live-line work can be divided into several aspects such as live-line testing, live-line inspection, and live-line maintenance. The objects of live-line work include electrical equipment in power plants and substations, overhead transmission lines, distribution lines, and distribution equipment.

[0003] Currently, when performing live-line disconnection or connection, workers need to temporarily set up a lead wire to ensure the normal operation of the power grid. Support tools are needed to fix the temporary lead wire during this work. Therefore, an insulated hanging rod for live-line work has been invented to fix the temporary lead wire, thereby freeing up workers and increasing their maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an insulated boom for live-line work.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An insulated boom for live-line working includes: a boom body, a clamp, and a hook; the clamp is disposed at the bottom of the boom body, and the hook is disposed at the top of the boom body; the clamp includes a rotating column, the center of which is provided with a slot, a rotating block is disposed in the slot, a locking block is disposed on the side of the rotating block near the slot, a fixed locking block is fixedly engaged with the locking block, and one end of the fixed locking block is rotatably connected to the rotating locking block; the hook includes a U-shaped hook, and two clamping blocks are disposed in the U-shaped hook.

[0007] In one embodiment, a first rotating shaft is provided on the right side of the fixed card block, and the first rotating shaft is rotatably connected to the right side of the rotating card block located in the fixed card block.

[0008] In one embodiment, the front shapes of both the rotating block and the fixed block are curved, and the front shape of the rotating block and the fixed block is elliptical when they are engaged together.

[0009] In one embodiment, a rotating rod is provided at the end of the fixing block away from the first rotating shaft, and a threaded hole is provided in the center of the rotating rod, in which a locking bolt is threadedly connected.

[0010] In one embodiment, the rod and the U-shaped hook are connected together by a rotating rod, and the front shape of the U-shaped hook is a "U" shape rotated 180°.

[0011] In one embodiment, the hook body of the U-shaped hook is hollow, and a second pivot is provided in the hook body at both ends near the rod body. The second pivot is rotatably sleeved with one end of the clamping block.

[0012] In one embodiment, spring hinges are provided in the hook bodies on both the left and right sides of the center of the U-shaped hook, and the side of the spring hinge away from the U-shaped hook is connected to the clamping block.

[0013] In one embodiment, the two clamping blocks are arranged in a mirror image at the center of the U-shaped hook groove, and the top of the clamping blocks is rotatably connected to the side of the U-shaped hook near it.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] This utility model discloses an insulated boom for live-line work. Through a hook located at the top of the boom, and the design of the hook's shape, along with the internal spring hinge and clamping block, the hook can be hooked onto the main lead line requiring maintenance. Simultaneously, a clamp located at the bottom of the boom, along with the positional relationship and connection method between the rotating block, rotating clamping block, rotating shaft, and fixed clamping block, allows the clamp to hold a temporary lead line. Therefore, this insulated boom for live-line work can be hung on the main line while simultaneously holding the temporary lead line, achieving the purpose of temporarily fixing the lead line during live-line disconnection and connection.

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0021] like Figure 1-2 As shown, an insulated boom for live-line working includes: a boom body 1, a clamp 2, and a hook 3; the clamp 2 is located at the bottom of the boom body 1, and the hook 3 is located at the top of the boom body 1; the clamp 2 includes a rotating column 24, with a slot in the center of the rotating column 24, in which a rotating block 25 is disposed, and a locking block 26 is disposed on the side of the rotating block 25 near the slot, with a fixing locking block 23 fixedly engaged on the locking block 26, and a rotating locking block 21 rotatably connected to one end of the fixing locking block 23; the hook 3 includes a U-shaped hook 31, with two clamping blocks 32 disposed in the U-shaped hook 31. It should be noted that both the clamp 2 and the hook 3 are made of insulating plastic, and the size of the clamp 2 and the hook 3 are adapted to the diameter of the electric wire.

[0022] like Figure 1-2 As shown in one embodiment, a first rotating shaft 22 is provided on the right side of the fixed clamping block 23. The first rotating shaft 22 is rotatably sleeved with the right side of the rotating clamping block 21 located in the fixed clamping block 23. The front shapes of both the rotating clamping block 21 and the fixed clamping block 23 are curved, and the front shape of the rotating clamping block 21 and the fixed clamping block 23 is elliptical when they are engaged together. A rotating rod is provided at the end of the fixed clamping block 23 away from the first rotating shaft 22. A threaded hole is opened in the center of the rotating rod, and a locking bolt 27 is threadedly connected in the threaded hole. It should be noted that the rotating clamping block 21 has a threaded hole corresponding to the locking bolt 27 at the end away from the first rotating shaft 22. This design allows the caliper 2 to clamp the temporary lead wire, and the rotating block 25 rotates longitudinally in the groove of the rotating column 24, while the rotating column 24 can rotate laterally. Therefore, the caliper 2 can clamp the temporary lead wire more flexibly.

[0023] like Figure 1-2As shown in one embodiment, the rod 1 and the U-shaped hook 31 are connected together by a rotating rod. The front shape of the U-shaped hook 31 is a "U" shape rotated 180°. The hook body of the U-shaped hook 31 is hollow, and a second rotating shaft 34 is provided in the hook body at both ends near the rod 1. The second rotating shaft 34 is rotatably sleeved with one end of the clamping block 32. Spring hinges 33 are provided in the hook bodies on both the left and right sides of the center of the U-shaped hook 31. The side of the spring hinge 33 away from the U-shaped hook 31 is connected to the clamping block 32. The two clamping blocks 32 are mirror images of each other in the center of the groove of the U-shaped hook 31, and the top of the clamping block 32 is rotatably connected to the side of the U-shaped hook 31 near it. It should be noted that this design allows the U-shaped hook 31 to hook onto the wire that needs repair, and at the same time, it allows the two clamping blocks 32 to automatically move towards the wire due to the spring hinges 33, clamping the wire and preventing it from easily falling off.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
