Technical Field

[0001] This invention relates to the field of power industry tools technology, and more specifically, to a grounding operation extension tool for the power industry. Background Technology

[0002] Temporary grounding wire connection is a core safety measure for power line outage operations. Currently, most domestic power distribution lines are located in the wild and residential areas, and there are often complex operating environments with crossing lines, parallel live lines, trees, and buildings blocking the way. Conventional grounding operating rods (insulated link rods) often cannot bypass obstacles to accurately reach the target conductor position.

[0003] In addition, the limited space inside the aerial work platform truck bed makes it extremely difficult for two people to work together, and it is very easy to accidentally touch adjacent live lines, which could lead to electric shock. In some obstructed scenarios, it is even impossible to complete the connection, so the power outage area must be expanded and trees must be cut down, which greatly increases the operating cost and the duration of the power outage.

[0020] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings 1-4.

[0021] This application provides a grounding operation extension tool for the power industry, such as... Figure 1 As shown, it includes a support rod 1, a clamping assembly 3, and a gripping assembly 5.

[0022] The main support rod 1 can be a single piece or it can be formed by assembling multiple sections, with the assembled components connected by threads.

[0023] The clamping component 3 is installed on one end of the supporting main rod 1, and the gripping component 5 is installed on the other end of the supporting main rod 1.

[0024] The clamping component 3 is used to clamp and fix the insulating link bar, and the gripping component 5 is for the worker to hold. The gripping component 5 can drive the clamping claw 34 in the clamping component 3 to move.

[0025] In this application, the staff only needs to hold the grip component 5 and operate the grip component 5 to make the clamping component 3 clamp the insulating link, which can increase the moving distance of the insulating link and achieve the purpose of delivering the insulating link to the designated position, thereby reducing the maintenance difficulty of power lines.

[0026] like Figure 2 As shown, specifically, the clamping assembly 3 includes a clamping base 31, four clamping claws 34, and a drive unit 4.

[0027] The clamping seat 31 is fixedly installed on one end of the supporting main rod 1. The clamping seat 31 includes at least an integrally formed base component 32 and a column component 33, and the column component 33 is installed on one end of the supporting main rod 1.

[0028] The four gripping claws 34 are hinged to the base component 32 of the gripping seat 31 at their middle parts and are arranged in a "V" shape. Each of the four gripping claws 34 has a "U"-shaped gripping arc block 35 installed at its end. The four gripping arc blocks 35 cooperate to form a hollow cylindrical structure for gripping and fixing the insulating link. A rubber insulating pad is fixed to the inner side of the gripping arc block 35. The interior of the insulating pad is machined with diamond-shaped anti-slip knurling, which maintains high friction even in humid or oily environments.

[0029] The driving component 4 is used to drive the four gripping claws 34 to move closer or further apart. The driving component 4 includes a driving base 41 and four linkage components 42.

[0030] Additionally, a drive rod 2 is slidably mounted inside the main support rod 1. The end of the drive rod 2 is fixedly connected to the drive base 41, and the gripping assembly 5 can drive the drive rod 2 to move. The drive rod 2 can also be composed of multiple segments, with the multiple components connected by threads.

[0031] The column component 33 has a cavity, and the drive base 41 is slidably connected to the cavity of the column component 33. Corresponding to the four linkage components 42, four clearance holes are provided on the side wall of the cavity. One end of each of the four linkage components 42 passes through the corresponding clearance hole and is rotatably mounted on the drive base 41. The other end of each of the four linkage components 42 is rotatably connected to one end of each of the four clamping claws 34.

[0032] The drive component 4 also includes a reset spring 43, which is located in the cavity of the column component 33 and sleeved on the drive rod 2. One end of the reset spring 43 is fixedly connected to the drive base 41, and the other end of the reset spring 43 is fixedly connected to the side wall of the cavity.

[0033] In this application, the gripping component 5 drives the drive rod 2 to move, the drive rod 2 moves the drive base 41, the drive base 41 moves the four linkage components 42, and the four linkage components 42 move the four clamping claws 34 to clamp the insulating link rod.

[0034] In addition, the return spring 43 is used to reset the multiple gripping claws 34.

[0035] like Figure 3 and Figure 4 As shown, the grip assembly 5 includes a grip handle 51, a grip lock 52, a second linkage 53, a third linkage 54, and a locking member 6.

[0036] The grip handle 51 is fixedly installed on the end of the support rod 1 away from the clamping assembly 3, and the grip lock 52 is rotatably installed on the grip handle 51.

[0037] One end of the second linkage 53 is rotatably connected to the end of the drive rod 2, the other end of the second linkage 53 is rotatably connected to the end of the third linkage 54, and the other end of the third linkage 54 is rotatably connected to the grip lock 52.

[0038] like Figure 4 As shown, the locking member 6 includes a ratchet 61, a pawl 62, a gear 63, and a rack 64; The rack 64 is fixedly connected to the grip lock 52. Both the rack 64 and the ratchet 61 are rotatably connected to the cavity wall of the inner cavity in the grip handle 51, and the rack 64 and the ratchet 61 are coaxial and relatively fixed. The gear 63 meshes with the rack 64.

[0039] The grip 51 is also provided with a movable part 7, and a pawl 62 is installed on the movable part 7. The ratchet 61 and the pawl 62 cooperate.

[0040] The movable component 7 includes a movable bar 71, a lever 72, and a movable spring 73.

[0041] The movable block is slidably mounted on the grip handle 51, and the lever 72 is fixedly connected to the movable bar 71. The grip handle 51 has a through hole for moving the lever 72. One end of the movable spring 73 is fixedly connected to the movable bar 71, and the other end of the movable spring 73 is fixedly connected to the grip handle 51. A locking spring 65 is also fixedly connected to the movable block, and the other end of the locking spring 65 is fixedly connected to the pawl 62.

[0042] In this application, when the worker needs to clamp the insulating link bar, he only needs to press the grip lock 52. At this time, the grip lock 52 drives the rack 64 to move. The rack 64 drives the gear 63 and ratchet 61 to rotate. At this time, the ratchet 61 is restricted from rotating in the opposite direction by the pawl 62. Therefore, the worker only needs to press the grip lock 52 until the four clamping arc blocks 35 are tightly fitted with the insulating link bar, and there is no need to press continuously.

[0043] When it is necessary to release the insulated link, push the lever 72 to move away from the main support rod 1. The lever 72 drives the movable bar 71 and the pawl 62 to move, so that the pawl 62 separates from the ratchet 61. At this time, under the action of the return spring 43, the multiple clamping claws 34 and the clamping arc block 35 are reset, thus achieving the purpose of releasing the insulated link.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

[0045] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
