Description

Bolt disassembling wrench

Technical Field

The utility model relates to the technical field of wrenches, in particular to a bolt disassembling wrench.

Background

In the fields of dangerous chemicals such as oil refining and chemical industry, lighting fixtures with higher explosion-proof level are used. The explosion-proof lamp cap of the high and dismantled and assembled lamp shade of explosion-proof grade that adopts at present is annular buckle design, and the outside reuse stainless steel jackscrew spacing buckle satisfies the assembly requirement. However, after the screw cap is used for a long time, the exposed part of the stainless steel jackscrew has an obvious oxide layer, under the long-term influence of the external use environment, the stainless steel jackscrew and the aluminum side wall of the lamp cap are corroded by bimetal to adhere, the stainless steel jackscrew is difficult to screw out by a common screw driver, the nut groove of the jackscrew can be damaged when the disassembly force is too large, and the screw is more difficult to take out after the edges and corners in the groove are rounded and flattened.

There are three general ways to solve the problem: firstly, spraying a screw loosening agent outside before disassembling, and then attempting to disassemble after a period of time, wherein the mode is time-consuming and poor in effect, and spraying a flammable screw loosening agent in an explosion-proof area, so that the risk coefficient is large; secondly, the round nuts with exposed outer sides are directly screwed by a pair of locking pliers or other clamping tools, because the jackscrew nuts are small and round, the jackscrew nuts are easy to slip in the force application process, and the exposed jackscrew parts can be broken when the force is too large, so that the operability is poor; thirdly, the new explosion-proof lamp cap is destructively dismantled or directly replaced, so that the explosion-proof performance of the explosion-proof lamp cap can be reduced or the purchase cost is relatively high.
