Description
Technical field
The utility model type belongs to a kind of VS1-type vacuum circuit breaker mechanism energy-stored spring dismounting utensil, is particularly suitable for electricity
Power equipment VS1-type vacuum circuit breaker is used when maintenance dismounts energy-stored spring.
Background technology
The overall structure of VS1-type vacuum circuit breaker is integration, Miniaturization Design.Breaker mechanism is compact design,
Switching-in spring when the adjustment service work for having closing iron core or mandril and replaces closing coil side before closing coil
The work in face must all remove energy-stored spring.It needs it to stretch when removing energy-stored spring, then could extract spring out and fix
Pivot pin.Since the elastic force of energy-stored spring is very big (700N), prodigious shearing force is generated to spring retaining pin, spring is caused to be fixed
Pivot pin is difficult dismounting.The main method of tradition dismounting is two people's cooperatings, and a people pries open energy-stored spring with steel screw knife to be made
Pin hole centering, another people extract spring retaining pin out.This dismounting is cumbersome and time consuming outer, and there is problems is：(1)
Energy-stored spring is not easy to control in dismounting, can bullet wound staff and equipment；(2) it is easy to be often subject to destruction force effect for energy-stored spring
Deformation, storage capacity, which declines, influences closing power；(3) dismounting technical difficulty is big, and cooperation required precision is high；(4) working strength is dismounted
Greatly, to physical fitness requirement height.
Utility model content
The utility model type technical problem to be solved is to overcome the deficiencies of existing technologies, and provides a kind of quick, province
Power portable beaker energy-stored spring replacer
The utility model type technical problem to be solved is realized using following technical scheme.
A kind of vacuum circuit breaker mechanism energy-stored spring replacer, including stretching shovel seat, afterburner handle, supporting rod, support shaft,
Fixed baffle, fixed baffle are welded on stretching shovel seat rear end, and stretching shovel seat rear end is provided with hole and fixes supporting rod, it is characterised in that：
The stretching shovel seat opens U-shaped shovel mouth, and the width for shoveling mouth is smaller 10mm than the diameter of energy-stored spring, and the edge of a knife height on both sides is different,
Asymmetry can inject in energy-stored spring：The first component, with described first
Part is connected and exerts a force with the matched circular ring part of human body waist, and the arm being arranged in the circular ring part both sides
Component.
One end of the afterburner handle opening is using Flash Butt Welding in stretching shovel seat rear end.
The fixed baffle be welded on stretching shovel seat rear end be provided with hole fix supporting rod, and have block prevent supporting rod to
After hurt sb.'s feelings.
The support shaft uses the steel screw of 8 × 20mm of Φ, convenient for being connected and fixed, rotating, support.
The utility model type is simple in structure, reasonable design, to exist when solving the problems, such as above-mentioned energy-stored spring dismounting, provides
It is a kind of that energy-stored spring is made to stretch the VS1 breaker mechanism energy-stored springs dismounting for being quickly drawn out spring retaining pin in pin hole pair
Device, can be such that energy-stored spring easily stretches, and not damage energy-stored spring intensity, and replacer is easy to assembly, operate with simply, one is complete
At assembly working, effect is good, efficient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model replacer；
Fig. 2 is the structural schematic diagram of the utility model afterburner handle.
Specific implementation mode
In order to which the technical means, creative features, achievable purpose and effectiveness for making the utility model type realize are easy to understand,
With reference to being specifically illustrating, the utility model type is expanded on further.
A kind of vacuum circuit breaker mechanism energy-stored spring replacer as shown in Figure 1 and Figure 2, including stretching shovel seat 1, reinforcing hand
The welding such as handle 2, supporting rod 3, support shaft 5, fixed baffle 6 are composed.Stretching shovel seat 1 is fixed on storage by operating personnel when use
On energy spring, supporting point being chosen by the limited bayonet 4 on supporting rod and is positioned, operation afterburner handle 2 makes energy-stored spring stretch
Fixed pivot pin can be extracted after pin hole centering out.It is fixed by stretching shovel seat 1 and implements to stretch energy-stored spring, in afterburner handle 2
Effect is not only laborsaving when operating down but also can be with one-handed performance, and another hand can extract spring retaining pin, the positioning of supporting rod 3 out
Bayonet 4 plays positioning supporting point and completes supporting role, and fixed baffle 6, which fixes supporting rod 3, prevents the bullet wound operator backward of supporting rod 3
Member, support shaft 5 play the role of steering and support.
It exerts a force in order to facilitate human body, the afterburner handle 2 includes：The first component 21 is connected with the first component 21
And with the matched circular ring part 22 of human body waist, and be arranged in the arm force section of 22 both sides of the circular ring part
Part 23.When need force when, circular ring part 22 is leaned against on belly so that arm force application part 23 leans against both sides, just with
The state position corresponding section that arm normally hangs down, facilitates force.
The basic principles and main features and advantage of the utility model type have been shown and described above.The technology people of the industry
For member it should be appreciated that the utility model type is not restricted to the described embodiments, what is described in the above embodiment and the description is only say
The principle of bright the utility model type, it is desirable that within the scope of protection the utility model type.Range is claimed by institute in the utility model type
Attached claims and its equivalent thereof.
