Abstract
The utility model discloses a vacuum circuit breaker combined floodgate spring assembly and disassembly tools, including the horizon bar, the front end of horizon bar is equipped with U type fork, and articulated on the horizon bar have the action bars, is equipped with the supporting shoe on the action bars. Be equipped with the recess along the axial on the action bars, the lower extreme setting of supporting shoe is set up in the recess and through the bolt. The back tip of horizon bar is equipped with the first insulation cover, the back tip of action bars is equipped with the insulating cover of second, the outside of supporting shoe is equipped with the insulating cover of third. The problem of change the coil in -process, its outside combined floodgate spring dismouting is difficult is solved, improve work efficiency. Application leverage learns the principle, combines handcart frame construction, can realize one -man operation, and work efficiency improves several times. Factor of safety is very high, can prevent to collapse spring, sliding spring accident's emergence completely.
Description
Technical field
The utility model belongs to electric power tool field, particularly relates to a kind of vacuum circuit breaker switching-in spring dismantling device.
Background technology
Current VS1 vacuum circuit breaker occupation rate of market reaches more than 90%, but along with its extensive use in electrical network, its closing coil burnout phenomenon also gets more and more, and because coil is at switching-in spring rear portion, more emat coil first must remove spring, and switching-in spring has very large elastic force, the problem of dismounting spring difficulty just shows especially out, need in working to pull down spring from spring upper end before, retaining element easily drops in handcart pallet, secondary is caused to overhaul, and do not have good method spring pliers can only be clamped disengaging hook, very easily collapse spring, cause equipment and personnel's injury.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of structure simple, the high and safe a kind of vacuum circuit breaker switching-in spring dismantling device easy to use of can increasing work efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vacuum circuit breaker switching-in spring dismantling device, comprise horizon bar, the front end of horizon bar is provided with U-shaped fork, and horizon bar is hinged with action bars, and action bars is provided with back-up block.
Described action bars is provided with groove vertically, and the lower end of described back-up block to be arranged in groove and to pass through bolt tightening.
The rearward end of described horizon bar is provided with the first insulation sleeve, and the rearward end of described action bars is provided with the second insulation sleeve, and the outside of described back-up block is provided with the 3rd insulation sleeve.
The utility model has the advantages that:
1, solve more in emat coil process, the problem of its outside switching-in spring dismounting difficulty, increases work efficiency.
2, use lever mechanics principle, in conjunction with cart frame structure, can realize one man operation, operating efficiency improves several times, and the take-down time was reduced to 5 minutes by 50 minutes.
3, safety coefficient is very high, can prevent the generation of collapsing spring, sliding spring contingency completely.Be applicable to 10 kilovolts of VS1 vacuum circuit breakers.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is U-shaped fork structural representation in Fig. 1.
Detailed description of the invention
Embodiment: vacuum circuit breaker switching-in spring dismantling device as shown in the figure, comprises horizon bar 5, the front end of horizon bar 5 is provided with U-shaped fork 1, and horizon bar 5 is hinged with action bars 2, and action bars 2 is provided with back-up block 3.
Described action bars 2 is provided with groove 9 vertically, and the lower end of described back-up block 3 to be arranged in groove 9 and to be tightened up by bolt 7.
The rearward end of described horizon bar 5 is provided with the first insulation sleeve 6, and the rearward end of described action bars 2 is provided with the second insulation sleeve 4, and the outside of described back-up block 3 is provided with the 3rd insulation sleeve 8.
Operating instruction: hand switch makes spring open certain gap, U-shaped fork 1 is inserted lower spring end, back-up block 3 when vertically being placed by action bars 2 on action bars 2 withstands edge under handcart upper frame, now horizon bar 5 is lifted slightly certain angle to make no longer to serve as a contrast strength between lower spring end hook and handcart pivot pin, now lay down jump ring and extract pivot pin out, lower spring end and handcart break off relations, and slowly reduce horizon bar strength, spring is recovered, releases energy.Now just spring can be removed, vacate space for maintenance, maintainer is changed the closing coil at spring rear portion.
