The invention has the beneficial effects as follows: adopt the gear transferring power that reliability is high, by the rotating forward of rocking handle, reversion controls the lifting of the pole-mounted circuit breaker lifted by crane, when needing static, by lockable mechanism, rocking handle is exerted a force towards casing direction, projection is pushed in groove, rocking handle no longer rotates, realize staticly implementing operation, when needing lifting, pull out rocking handle, the postive stop baffle that rocking handle is arranged can limit the distance of rocking handle pull-out, driven gear and driving gear is avoided to depart from, projection now on rocking handle departs from the groove of casing, the lifting of pole-mounted circuit breaker can be implemented again by manual operation rocking handle, adopt the steel strand wire of good toughness lifting working strength high.In a word, structure of the present invention is simple, volume is little, low to the requirement of infrastructure periphery environment for use and infrastructure, can the more convenient lifting operation carrying out pole-mounted circuit breaker more flexibly, install additional or change whole in the engineering of pole-mounted circuit breaker, not only reduce the expense of construction crane used and manpower, and compared with crane operation, flexibility is high, easy for installation, suitable environment is extensive.
On the basis of technique scheme, the present invention can also do following improvement.
Further, also comprise the support be horizontally set in the middle part of electric pole, one end of described support is provided with two anchor ears be oppositely arranged, and the other end is provided with the spacing ring passed for described steel strand wire.
The beneficial effect of above-mentioned further scheme is adopted to be, to swing back and forth the installation of inconvenient pole-mounted circuit breaker for avoiding the free end of the steel strand wire after through pulley, or in lifting process, avoid steel strand wire to depart from too much therefore increase support carrying out spacing to steel strand wire, ensure that steel strand wire are movable within the specific limits when being elevated.
Further, the free end of described steel strand wire is provided with suspension hook.
The beneficial effect of above-mentioned further scheme is adopted to be conveniently directly be connected with pole-mounted circuit breaker.
Further, described spacing ring is oval.
The beneficial effect of above-mentioned further scheme is adopted to be facilitate steel strand wire to penetrate in spacing ring, support overall width can also be ensured, good looking appearance.
