Description
Technical field
The utility model relates to a kind of electric power facility maintenance tool, particularly spring mechanism of circuit breaker special tool for examination and repair.
Background technology
When circuit breaker carries out breaking-closing operating, when defective the needs spring mechanism of circuit breaker is disassembled and overhauled of breaker open operation time found in test.Two problems now appear, the one, first will be by spring-compressed during the dismounting spring mechanism, the elastic force of spring is very large, and the bayonet lock connecting rod is in the spring flat gasket centre position, if use a jack to make the jack can not effective output in centre position because interposition is equipped with the bayonet lock connecting rod, and use being synchronized with the movement that two jack exert oneself simultaneously to be difficult for holding; The second, because mechanism's ground clearance is larger, need to below jack, pad very high supporter, there is the unsettled phenomenon of support.Based on the problems referred to above, the specific purpose tool that needs a kind of applicable site examining and repairing of design to use, to reach the purpose conveniently breaker spring disassembled.
The utility model content
The utility model provides a kind of highly versatile, spring mechanism of circuit breaker special tool for examination and repair easy to use for solving the defect of above-mentioned prior art.
Problem described in the utility model solves by the following technical programs:
A kind of spring mechanism of circuit breaker special tool for examination and repair, special feature is: it comprises base, guide rod, stay pipe, jacking cup and jack, described base, guide rod, stay pipe and jacking cup are connected from the bottom to top successively, form removable supporting structure.
Above-mentioned spring mechanism of circuit breaker special tool for examination and repair, described base bottom is provided with base plate, fixing jack mount pad on base plate, jack mount pad both sides are respectively equipped with the jack clamping knob, and jack is positioned at the jack mount pad; Also be provided with guide pipe on base, guide pipe is positioned at jack mount pad top, and the base plate both sides are provided with support bar, and the support bar two ends are affixed base plate and guide pipe respectively.
Above-mentioned spring mechanism of circuit breaker special tool for examination and repair, described guide rod bottom is inserted in guide pipe, and guide rod top and stay pipe are pegged graft, and the guide rod bottom contacts the top at jack.
Above-mentioned spring mechanism of circuit breaker special tool for examination and repair, be axially arranged with row's supporting pipe hole along it on described stay pipe, each supporting pipe hole radially connects stay pipe, uniform radial guiding rod through-hole on described guide rod, and clamping screw is fixed guide rod and stay pipe through supporting pipe hole and guide rod through hole.
Above-mentioned spring mechanism of circuit breaker special tool for examination and repair, peg graft in the top of described jacking cup and stay pipe, and by radially the clamping screw through said two devices is fastening.
When the utility model overhauls for the solution spring mechanism of circuit breaker, spring is dismantled problem and has designed a kind of specific purpose tool.Described specific purpose tool comprises base, support bar and guide pipe and jacking cup, each part mentioned above can be dismantled as individual components, be easy to carry and take care of, take up room little, can be assembled into one efficiently during use, wherein, the base supporting & stablizing is reliable, stretching out highly of stay pipe can be regulated, and the jacking cup can, according to the replacing spring of circuit breaker of different size, be used so can be applicable to the overhaul of line breaker of differing heights, different size.When the utility model overhauls for spring mechanism of circuit breaker, can greatly increase work efficiency, alleviate maintainer's labour intensity, and improve the fail safe of service work.
