Abstract
The invention discloses an assembling and disassembling tool for a switching-on spring of a vacuum circuit breaker. The assembling and disassembling tool comprises a horizontal rod; a U-shaped fork is arranged at the front end of the horizontal rod; an operation rod is hinged to the horizontal rod and provided with a supporting block. A groove is formed in the operation rod in the axial direction, and the lower end of the supporting block is arranged in the groove and fastened by a bolt. A first insulation sleeve is arranged at the rear end of the horizontal rod, a second insulation sleeve is arranged at the rear end of the operation rod, and a third insulation sleeve is arranged outside the supporting rod. The problem that in the coil replacement process, an outer switching-on spring is difficult to assemble and disassemble is avoided, and working efficiency is improved. By applying the lever mechanics principle and combining with a handcart framework structure, single-person operation can be achieved, and working efficiency is improved by many times. The safety factor is high, and the accidents of spring collapsing and spring sliding can be completely prevented.
Description
Technical field
The invention belongs to electric power tool field, particularly relate 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 object of the invention is to the shortcoming overcoming above-mentioned prior art, provide 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 object of the invention is to be 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.
Advantage of the present invention is:
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 invention.
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.
