Description

Technical Field

[0001] This utility model relates to the field of GIS switchgear disassembly and maintenance, and in particular to a device that facilitates the installation and disassembly of the conductive rod of a combined electrical appliance. Background Technology

[0002] With the rapid development of the power industry, GIS (Gas Insulated Switchgear) circuit breakers are being used more and more widely in power systems. GIS circuit breakers have advantages such as small footprint, high reliability, and convenient maintenance.

[0003] During the installation, inspection, and maintenance of GIS circuit breakers, it is necessary to clamp the conductive rods. Currently, during the disassembly and assembly of the internal conductive rods, manual operation is mostly used to insert and remove them. This is not only inefficient, but also prone to instability due to manual fixing, which can easily cause damage to the outer surface of the conductive rod or the spring contacts, affecting the quality of equipment maintenance and posing potential risks to equipment performance and operational safety. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a device that facilitates the installation and disassembly of conductive rods in combined electrical appliances. This device can flexibly and accurately clamp the conductive rods, improve work efficiency, reduce safety risks, and provide strong support for the installation, inspection, and maintenance of GIS circuit breakers.

[0005] The present invention provides a device for facilitating the installation and disassembly of conductive rods in combined electrical appliances, comprising a clamping assembly and a gripping assembly. The clamping assembly includes a first clamping member and a second clamping member that are relatively open or closed around one end. The first clamping member has a first arc-shaped groove on the side facing the second clamping member, and the second clamping member has a second arc-shaped groove on the side facing the first clamping member. The gripping assembly includes a handle and two handles. The handle and one handle are respectively connected to the two ends of the second clamping member, and the other handle is connected to the end of the first clamping member away from the handle.

[0006] Preferably, the angles of both the first arc-shaped groove and the second arc-shaped groove are less than 180°.

[0007] Preferably, rubber pads are provided on the inner walls of both the first and second arc-shaped grooves.

[0008] Preferably, both the first clamping member and the second clamping member are provided with through holes, and bolts are inserted through the through holes. Nuts are threaded onto the bolts, and the first clamping member and the second clamping member are rotatably connected by the bolts.

[0009] Preferably, the handle is a round tube.

[0010] Preferably, both the first clamping member and the second clamping member have internal threads, and one end of the handle has an external thread. The two handles are threadedly connected to the first clamping member and the second clamping member, respectively.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This invention, after clamping the conductive rod with the first and second clamping members, allows for vertical force application by holding one handle and two levers on both sides, safely and smoothly removing the conductive rod vertically without damaging its outer surface or spring contacts. This device can clamp the conductive rod flexibly and accurately, has a simple structure, is easy to manufacture, and is convenient to operate, improving work efficiency, reducing safety risks, and providing strong support for the installation, inspection, and maintenance of GIS circuit breakers.

[0017] Example 1

[0018] like Figures 1-3 As shown in the figure, this embodiment proposes a device for facilitating the installation and disassembly of the conductive rod of a combined electrical appliance, which includes a clamping component and a gripping component. The user operates the gripping component to drive the clamping component to clamp the conductive rod 7.

[0019] The clamping assembly includes a first clamping member 2 and a second clamping member 3 that rotate open or close relative to one end. The first clamping member 2 has a first arc-shaped groove on the side facing the second clamping member 3, and the second clamping member 3 has a second arc-shaped groove on the side facing the first clamping member 2. The angles of both the first and second arc-shaped grooves are less than 180°, meaning that the distribution range of the arc-shaped groove's cross-section edge is less than 180° with the center of the groove as the center. The two arc-shaped grooves effectively clamp the conductive rod 7 to the inside. To improve the stability when clamping the conductive rod 7, rubber pads 4 are provided on the inner walls of both the first and second arc-shaped grooves. Specifically, the rubber pads 4 can be attached by adhesive. The rubber pads 4 increase friction when clamping the conductive rod 7 and also prevent scratches on the surface of the conductive rod 7, providing good protection.

[0020] like Figure 1 and Figure 2 As shown, the grip assembly includes a handle 1 and two handles 6. The handle 1 and one handle 6 are respectively connected to the two ends of the second clamping member 3, and the other handle 6 is connected to the end of the first clamping member 2 away from the handle 1. The handle 1 is a round tube, or it can also adopt other shapes to meet the user's stable grip requirements.

[0021] In this embodiment, when clamping the conductive rod 7, the first clamping member 2 is turned open using a handle 6, allowing the first clamping member 2 and the second clamping member 3 to close and respectively lock onto both sides of the conductive rod 7. Then, by holding one handle 1 and two handles 6 on both sides, vertical force is applied to safely and smoothly remove the conductive rod 7 vertically without damaging the outer surface of the conductive rod 7 or the spring contact finger. Similarly, when installing the conductive rod 7, this device clamps the conductive rod 7 and performs vertical insertion. This embodiment can flexibly and accurately clamp the conductive rod 7, has a simple structure, is easy to manufacture, is easy to operate, improves work efficiency, reduces safety risks, and provides strong support for the installation, inspection, and maintenance of GIS circuit breakers.

[0022] Example 2

[0023] like Figures 1-3 As shown in this embodiment, a device for facilitating the installation and disassembly of the conductive rod of a combined electrical appliance is proposed. Compared with Embodiment 1, in this embodiment, both the first clamping member 2 and the second clamping member 3 are provided with through holes, through which bolts 5 are inserted. Nuts are threaded onto the bolts 5, and the first clamping member 2 and the second clamping member 3 are rotatably connected by the bolts 5. The rotatable connection between the first clamping member 2 and the second clamping member 3 is achieved through the through bolts 5, and the nuts prevent the bolts 5 from falling off. The bolts 5 are not threaded onto the first clamping member 2 and the second clamping member 3; instead, they pass through the through holes on the first clamping member 2 and the second clamping member 3 to provide a support point for the rotation process.

[0024] Example 3

[0025] like Figures 1-3As shown in the figure, this embodiment proposes a device for facilitating the installation and disassembly of the conductive rod of the combined electrical appliance. Compared with the first embodiment, in this embodiment, the first clamping member 2 and the second clamping member 3 both have internal threads, and one end of the handle 6 has an external thread. The two handles 6 are respectively threaded to the first clamping member 2 and the second clamping member 3, and the two handles 6 can be screwed onto the first clamping member 2 and the second clamping member 3 respectively, making assembly convenient.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
