Description

Disassembly switch static contact special tool

technical field

The utility model belongs to dismantling tools, in particular to a special tool for dismantling the bolts on the static contacts of the isolating switch.

Background technique

On the static contact of the disconnector, multiple components are connected by bolts, especially the contact fingers of the static contact. When replacement or maintenance is required, the bolts need to be disassembled or tightened. Since the bolts or fingers of the static contacts of the isolating switch are generally installed in a narrow space, it is inconvenient to disassemble them with a wrench.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide a special tool for removing the static contact of the isolating switch, which can conveniently and labor-savingly install and disassemble the bolts or contact fingers on the static contact of the isolating switch. ``

In order to achieve the above object, the utility model adopts the following technical solutions:

A special tool for removing the static contact of a disconnector, comprising a handle and a dismounting head, the handle and the dismounting head are set separately, the lower part of the handle is provided with a plug-in end, and the dismounting head includes an upper splicing piece connected as one and a dismounting lower part The middle part of the upper end of the splicing piece is provided with an insertion hole corresponding to the insertion end, and the disassembly piece is provided with an inner hole corresponding to the part to be disassembled on the static contact of the isolating switch.

The above-mentioned special tool for removing the static contact of the isolating switch, the cross-section of the plug-in end is an equilateral triangle, and a positioning column is also provided at the midpoint of one side of the plug-in end, correspondingly, the plug-in hole is also an equilateral triangle, and the plug-in hole is also an equilateral triangle. A positioning hole corresponding to the positioning column of the plug-in end is provided.

In the special tool for removing the static contact of the isolating switch, the section of the plug-in end is a hypotenuse triangle or a long strip, and the shape of the plug-in hole corresponds to that of the plug-in end.

In the special tool for removing the static contact of the isolating switch, the inner hole is an inner screw hole.

In the special tool for removing the static contact of the isolating switch, the shape of the inner hole corresponds to the contact finger of the static contact.

By adopting the above technical scheme, the utility model has the following advantages: since the dismounting head is provided with an inner hole corresponding to the part to be dismantled on the static contact of the isolating switch, it is convenient to insert the dismounting head into the part to be disassembled and twist the handle. Disassemble the bolts or contact fingers on the static contact of the isolating switch with little effort. It is convenient for the maintenance or replacement of the static contact of the isolating switch. On the other hand, the handle and the disassembly head are set separately, which is convenient for carrying and assembly.

Detailed ways

As shown in Figure 1-Figure 4, a special tool for removing the static contact of the disconnector includes a handle 1 and a removal head 2, the handle 1 and the removal head 2 are set separately, and the lower part of the handle 1 is provided with a plug-in terminal 3, The dismounting head 2 includes an upper splicing piece 4 and a lower dismounting piece 5 that are connected as one, and an insertion hole 7 corresponding to the plug-in end is provided at the middle part of the splicing piece upper end, and an isolation joint is provided on the dismounting piece 5. The inner hole 6 corresponding to the part to be disassembled on the static contact of the switch.

As shown in Figure 2, the cross-section of the plug-in end is an equilateral triangle, and a positioning column 8 is also provided at the midpoint of one side of the plug-in end, and correspondingly, the plug-in hole 7 is also an equilateral triangle, and the plug-in hole is also provided with a The positioning hole 9 corresponding to the positioning post of the insertion end.

The section of the plug-in end of the utility model can also be a hypotenuse triangle or a long strip, and the shape of the plug-in hole corresponds to the plug-in end. All can realize the function of the utility model.

The shape of the inner hole 6 of the utility model is made into different shapes according to different needs. When the bolt needs to be disassembled, the inner hole 6 is set as an inner screw hole, which is convenient for dismounting the bolt. When the contact finger needs to be disassembled, the shape of the inner hole 3 is set to a shape corresponding to the contact finger, so as to facilitate disassembly of the contact finger.

Working process: Insert the disassembly head into the bolt or contact finger of the static contact of the isolating switch that needs to be disassembled, then insert the plug end of the handle into the socket hole of the disassembly head, and twist the handle hard, and the isolating switch can be statically disassembled. The bolts or fingers on the contacts are removed, or tightened. Easy to replace or repair.
