Abstract
10kV breaker energy storage spring dismounting pincers, comprise that pressure head passes through the jaw of the hinged formation of axle core, jaw bottom is provided with fixed handle and the flexible handle of controlling its folding, between fixed handle and flexible handle, establishes back-moving spring, fixed handle bottom is provided with bolt, and bolt is rotary with nut through flexible handle.10kV breaker energy storage spring dismounting of the present utility model pincers are by lever principle, by the disassemble and assemble work of energy accumulation spring become efficiently, simple, safe safe.
Description
Technical field
The utility model relates to a kind of energy accumulation spring dismounting pincers, a kind of breaker energy storage spring folding dress specific purpose tool of using in especially applicable 10kV breaker mechanism service work.
Background technology
In the service work of 10kV breaker mechanism, energy accumulation spring disassemble and assemble work is being thorny, a dangerous but indispensable processing step, and careless slightly its spring that can cause collapses, and from individual damage equipment, workmen's personal safety is caused to serious harm.At present, on market, without its specific purpose tool, sell, producer is not equipped with its specific purpose tool yet.When the existing conventional tool of upkeep operation librarian use (as screwdriver, nipper pliers etc.) is carried out its operation, labour intensity is large, success rate is low, and very easily damages energy accumulation spring.
Application number is that the energy accumulation spring that the patent of CN200620031076.1 discloses a kind of vacuum circuit-breaker press-fits pincers, hinged by two arc motion arms with U-lag plug, this press-fits pincers and is mainly used in vacuum circuit-breaker, be energy accumulation spring axially on afterburning, draw energy accumulation spring to Len req, this kind of afterburning mode can cause energy accumulation spring to damage by undue force.
Utility model content
The purpose of this utility model is while carrying out its operation for conventional tool in prior art, labour intensity is large, success rate is low, and very easily damage the problems such as energy accumulation spring, the 10kV breaker energy storage spring dismounting that a kind of disassemble and assemble work becomes efficiently, simple, safety is safe pincers are provided.
To achieve these goals, the technical solution adopted in the utility model is: 10kV breaker energy storage spring dismounting pincers, comprise that pressure head passes through the jaw of the hinged formation of axle core, jaw bottom is provided with fixed handle and the flexible handle of controlling its folding, between fixed handle and flexible handle, establish back-moving spring, fixed handle bottom is provided with bolt, and bolt is rotary with nut through flexible handle.
The inner both sides of described pressure head are provided with pressure tooth.
Described pressure tooth is provided with diaphragm.
Compared with prior art, 10kV breaker energy storage spring dismounting of the present utility model pincers are by lever principle, by the disassemble and assemble work of energy accumulation spring become efficiently, simple, safe safe.Precession by nut makes pressure head produce radial pressure, thereby the powerful elastic potential energy of energy accumulation spring is overcome, and utilizes tightening bolt to exert pressure and can keep the constant pressure of pressure head, presses tooth can reduce lifting surface area and increases pressure.The utility model material mainly adopts medium carbon steel to make, and intensity is large, corrosion-resistant, physical life is long, efficient, safe, convenient.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
As shown in Figure 1,10kV breaker energy storage spring dismounting pincers, comprise that pressure head 1 is by the jaw of axle core 2 hinged formation, jaw bottom is provided with fixed handle 3 and the flexible handle 4 of controlling its folding, between fixed handle 3 and flexible handle 4, establish back-moving spring 5, fixed handle 3 bottoms are provided with bolt 6, and bolt 6 is rotary with nut 7 through flexible handle 4.The inner both sides of pressure head 1 are provided with presses tooth 8, reduces contact area and increases pressure.Press tooth 8 to be provided with diaphragm, can reduce the scratch to energy accumulation spring.
The utility model passes through lever principle, the pressure of fixed handle 3 is passed to pressure head 1, pressure head 1 pressure, by pressing tooth 8 to be pressed into spring radially, makes it extend axially certain length, to meet dismounting process requirement, when workmen's grip does not reach relevant pressure, can utilize nut 7 to exert pressure to bolt 6, and handle is fixed, to keep constant pressure, after energy accumulation spring disassemble and assemble work completes, tightening nut is unclamped tightly.This tool operation is simple and convenient, safe and efficient.Main material adopts medium carbon steel, high-strength aluminum alloy etc., and intensity is large, corrosion-resistant, physical life is long, efficient, safe, convenient.
