Description

Technical Field

[0001] The present application relates to the field of electric power technology, and more specifically, to an electric power maintenance tool. Background Art

[0002] When inspecting high-voltage electrical equipment in the power system, it is necessary to shut down the power, test the electricity, and hang the ground wire. The known high-voltage tester structure is composed of a test element and an insulating rod that are fixedly connected. In actual work, since the installation position of the semi-high-rise equipment (such as transformers, structural brackets) of each substation is too high from the ground, and the high-voltage testers used in lines of different voltage levels have different specifications, the outer diameter of the insulating rod of the high-voltage tester is also different. For high-voltage testers of different specifications, different multi-stage telescopic rods are required, which is cumbersome to use.

[0003] The document with the prior art announcement number CN216816755U provides a telescopic device for high-voltage testers to perform high-altitude electrical testing. In the related technology of the device, the diameter of the second slot is adjusted by using a reducing assembly, so that the diameter of the second slot can be adapted to the outer diameter of the insulating rod of high-voltage testers of different specifications. Through this structure, it is convenient for operators to fix high-voltage testers of different specifications through the reducing assembly to perform electrical testing of lines of different voltage levels.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device clamps and fixes high-voltage testers of different specifications by adjusting multiple adjustment knobs, which is not only cumbersome to operate, but also has a poor fixing effect of the high-voltage tester.

[0005] In view of this, we propose an electric power maintenance tool. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides an electric power maintenance tool.

[0007] The power maintenance tool provided in this application adopts the following technical solution:

[0008] An electric power maintenance tool, comprising:

[0009] A plug-in frame equipped with an insulating telescopic rod;

[0010] The elastic pressing piece is hingedly installed in the plug-in frame;

[0011] A transmission gear is fixedly connected to one end of the elastic pressing piece;

[0012] A card rod frame is slidably connected in the plug-in frame;

[0013] The tooth plate is fixedly connected to one side of the clamping rod frame and meshes with the transmission gear for transmission;

[0014] The fastening screw is threadedly connected to one side of the frame and can be tightly pressed and limited with the tooth plate.

[0015] By adopting the above technical solution, the high-voltage tester is inserted into the insertion frame and is in rolling friction contact with the elastic pressing part, so that the elastic pressing part is limited and flipped, and at the same time, the clamping rod frame of the meshing transmission is driven to limit and move, so that the inserted high-voltage tester is tightly pressed and limited, and the position of the clamping rod frame is limited under the rotation of the fastening screw, thereby ensuring the stability and convenience of the installation of the high-voltage tester.

[0017] By adopting the above technical scheme, the insertion hole of the water drop-shaped structure can be used to tightly abut and limit the inserted high-voltage tester, thereby ensuring the firmness of the installation of the high-voltage tester. At the same time, with the coordinated operation of the test rod and the warning LED lamp beads, it can be determined whether the installed high-voltage tester has leakage during use, thereby improving the safety of power maintenance.

[0019] By adopting the above technical scheme, the inserted high-voltage tester is clamped and limited by the movement of the clamping rod frame. At the same time, the displaced clamping rod frame drives the hingedly installed extrusion rod to flip under the abutment limit of the tilting rod, so that the flipped tilting rod pushes the slidingly connected abutment angle plate to move, further abutting and limiting the inserted high-voltage tester, thereby ensuring the firmness of the installation of the high-voltage tester.

[0020] As an optional solution of the technical solution of the present application document, the elastic pressing part includes a roller, and a sliding sleeve A and a sliding sleeve B are hingedly installed on the outside of the roller. The sliding sleeve A and the sliding sleeve B are arranged in a symmetrical structure, and the sliding sleeve A and the sliding sleeve B are elastically connected with a pressure rod through a spring part. The pressure rod is hingedly installed on the insertion frame, and one of the pressure rods is connected and fixed to the transmission gear.

[0021] By adopting the above technical solution, the inserted high-voltage electroscope is utilized to have rolling friction contact with the roller, so that the roller drives the externally rotatably installed sliding sleeve A and sliding sleeve B to be limited and elastically contracted outside the pressure rod, thereby realizing the abutment between the roller and the high-voltage electroscope and driving the meshing transmission action of the transmission gear and the toothed plate.

[0022] As an optional solution of the technical solution of the present application document, the rod frame is arranged in a cone-shaped tower structure, a rubber layer is pasted on the inner wall of the rod frame, and a plurality of balls for reducing friction resistance are embedded on the outside of the rod frame.

[0023] By adopting the above technical solution and utilizing the clamping rod frame provided with a cone-shaped tower structure, the clamping rod frame can be made more secure when it is abutted against the high-voltage electroscope.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application utilizes a high-voltage electroscope to be inserted into an insertion frame and to have rolling friction contact with an elastic pressing part, so that the elastic pressing part performs a limit flipping action while driving the limit movement of the engaging transmission clamping rod frame, thereby tightly pressing and limiting the inserted high-voltage electroscope, and limiting the position of the clamping rod frame under the rotation of the fastening screw, thereby ensuring the stability and convenience of the installation of the high-voltage electroscope.

[0026] 2. In the present application, the inserted high-voltage tester is clamped and limited by the movement of the clamping rod frame. At the same time, the displaced clamping rod frame drives the hingedly installed extrusion rod to flip under the abutment limit of the tilting rod, so that the flipped tilting rod pushes the slidingly connected abutment angle plate to move, further abutting and limiting the inserted high-voltage tester, thereby ensuring the firmness of the installation of the high-voltage tester.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-4 , a power maintenance tool in the power maintenance tool recorded in the embodiment of the present application includes:

[0034] A plug-in frame 1 is installed with an insulating telescopic rod;

[0035] The elastic pressing piece 2 is hingedly installed in the insertion frame 1;

[0036] The transmission gear 3 is fixedly connected to one end of the elastic pressing part 2;

[0037] The card rod frame 4 is slidably connected in the plug-in frame 1;

[0038] The tooth plate 5 is fixedly connected to one side of the clamping rod frame 4 and meshes with the transmission gear 3 for transmission;

[0039] The fastening screw 6 is threadedly connected to one side of the insertion frame 1 and can be tightly pressed and limited with the tooth plate 5.

[0040] The electric power inspection tool utilizes a high-voltage tester to be inserted into an insertion frame 1 and to make rolling friction contact with an elastic pressing piece 2, so that the elastic pressing piece 2 is limited and flipped, and at the same time, drives a clamping rod frame 4 of a meshing transmission to limit and move, so as to tightly press and limit the inserted high-voltage tester, and limit the position of the clamping rod frame 4 under the rotation of a fastening screw 6, thereby ensuring the stability and convenience of the installation of the high-voltage tester.

[0041] Reference Figure 3 and Figure 1 In the power maintenance tool recorded in the embodiment of the present application, the insertion hole opened in the middle of the plug-in frame 1 is in a water drop-shaped structure, an insulating film is pasted on the inner wall, and a test rod is embedded on the top surface of the plug-in frame 1, and a warning LED lamp bead is electrically connected to the outside of the test rod, and a tilting rod 11 is fixedly connected to one side of the plug-in frame 1, and an extrusion rod 12 is slidably connected to the outside of the tilting rod 11, and an abutment angle plate 13 is slidably connected to one end of the extrusion rod 12, and the abutment angle plate 13 with a rubber layer pasted on the inner wall slides with the plug-in frame 1, and the other end of the extrusion rod 12 is hingedly installed with the card rod frame 4.

[0042] The power inspection tool can tightly abut and limit the inserted high-voltage tester by utilizing the insertion hole of the water drop-shaped structure, thereby ensuring the firmness of the installation of the high-voltage tester. At the same time, under the coordinated operation of the test rod and the warning LED lamp bead, it can be judged whether the installed high-voltage tester has leakage during use, thereby improving the safety of power inspection. While the clamping rod frame 4 moves to limit the inserted high-voltage tester, the displaced clamping rod frame 4 drives the hingedly installed extrusion rod 12 to flip under the abutment limit of the tilting rod 11, so that the flipped tilting rod 11 pushes the slidingly connected abutment angle plate 13 to limit and move, further abutting and limiting the inserted high-voltage tester, thereby ensuring the firmness of the installation of the high-voltage tester.

[0043] Reference Figure 4 and Figure 1 In the power maintenance tool recorded in the embodiment of the present application, the elastic pressing part 2 includes a roller 21, and a sliding sleeve A22 and a sliding sleeve B23 are hingedly installed on the outside of the roller 21. The sliding sleeve A22 and the sliding sleeve B23 are arranged in a symmetrical structure, and the sliding sleeve A22 and the sliding sleeve B23 are elastically connected with a pressure rod 24 through a spring member. The pressure rod 24 is hingedly installed on the insertion frame 1, and one of the pressure rods 24 is connected and fixed to the transmission gear 3.

[0044] The electric power inspection tool utilizes the inserted high-voltage tester to generate rolling friction contact with the roller 21, so that the roller 21 drives the externally rotatably mounted sliding sleeve A22 and the sliding sleeve B23 to be limited outside the pressure rod 24 and elastically contract, thereby realizing the abutment between the roller 21 and the high-voltage tester and driving the meshing transmission action of the transmission gear 3 and the toothed plate 5.

[0045] Reference Figure 2 In the power maintenance tool recorded in the embodiment of the present application, the rod frame 4 is arranged in a cone-shaped structure, a rubber layer is pasted on the inner wall of the rod frame 4, and a plurality of balls for reducing friction resistance are embedded on the outside of the rod frame 4.

[0046] The electric power maintenance tool can make the clamping rod frame 4 more firm when it is attached to the high-voltage electroscope by using the clamping rod frame 4 with a cone-shaped structure.

[0047] Working principle: When installing high-voltage testers of different specifications, first, loosen the fastening screw 6 so that the fastening screw 6 is separated from the abutment limit to the tooth plate 5, and then insert the rod body of the high-voltage tester into the insertion hole of the teardrop-shaped structure of the insertion frame 1. At this time, the high-voltage tester and the roller 21 are in rolling friction contact, so that the roller 21 drives the sliding sleeve A22 and the sliding sleeve B23 installed externally to be limited outside the pressure rod 24 to elastically shrink, and the pressure rod 24 that is flipping drives the transmission gear 3 fixedly connected at one end to mesh with the tooth plate 5 for transmission, thereby pushing the clamping rod frame 4 to limit movement, and the inserted high-voltage tester is tightly pressed and limited;

[0048] While the clamping rod frame 4 moves to limit the inserted high-voltage electroscope, the displaced clamping rod frame 4 drives the hingedly installed extrusion rod 12 to flip under the abutment limit of the tilting rod 11, and the flipped tilting rod 11 pushes the slidingly connected abutment angle plate 13 to limit the movement, further abutting and limiting the inserted high-voltage electroscope;

[0049] Finally, tighten the fastening screw 6 to fix the position of the clamping rod frame 4.
