Abstract

The invention discloses a disassembling tool for a disconnecting link clamping spring. The disassembling tool comprises a horizontal bracket, a lead screw nut pair, a thrust bearing assembly and a linear bearing assembly; the horizontal bracket comprises a bottom plate and two support clamping grooves fixed in the bottom plate and used for supporting a disconnecting link; the lead screw nut pair comprises a nut fixed on the bottom plate and a lead screw matched with the nut; the thrust bearing assembly is arranged on the end part of the lead screw and used for pushing one end of a disconnecting link ejector rod; and the linear bearing assembly is used for being arranged on the ejector rod in a sleeving manner and jacking between the spring and the support clamping grooves. By adopting thetool to disassemble the disconnecting link, stability and reliability are achieved, low labor intensity of an operator is realized, and falling over of the operator can be avoided effectively.

Description

technical field [0001] The invention belongs to the field of maintenance tools for electric equipment, and in particular relates to a tool for dismantling a clamping spring of a knife switch. Background technique [0002] At present, the GW16 type (single-column single-arm vertical telescopic type) knife switch (hereinafter referred to as the 16-type knife switch) is widely used to isolate the overhauled equipment from the live bus or switch the unloaded bus. However, after the equipment has been in operation for a long time, the clamping spring in the knife switch is corroded and aged. This will cause the clamping force of the knife switch to weaken, the contact resistance to increase, and the equipment to overheat or even burn out; at this time, the knife switch needs to be disassembled and overhauled, and the clamping spring needs to be maintained or replaced. After the clamping spring is compressed, it is fixed on the push rod by the limit pin. Therefore, regardless of...
