Description
Technical field
The utility model relates to power equipment Work tool, more particularly, relates to a kind of grounding switch bite handling implement.
Background technology
Numerous converting equipments such as voltage levels circuit breaker, current transformer, voltage transformer, transformer, lightning arrester and isolating switch are installed in transformer station, circuit breaker two ends are respectively provided with a grounding switch, lightning arrester, current transformer, voltage transformer one end install one grounding switch, transformer senior middle school low-pressure side is respectively installed a grounding switch, and isolating switch two ends are respectively provided with a grounding switch.When converting equipment interruption maintenance, the corresponding grounding switch that need close imports substation ground network by capacitive apparatus residual charge or converting equipment induced electricity, to prevent that capacitive apparatus residual charge or converting equipment induced electricity from hurting sb.'s feelings.Because grounding switch joint is that metal material is made, throughout the year exposed in air, grounding switch joint is very easy to oxidized and produces oxide-film, and grounding switch joint opening size is diminished.After the work of converting equipment interruption maintenance completes, need to disconnect grounding switch power transmission, due to the oxidized size decreases of grounding switch joint, staff cannot disconnect in terrestrial operation, need to carry out ascend operation by means of high-altitude operation vehicle.For preventing that high-altitude operation vehicle from breaking converting equipment or mistake forward (FWD) electricity interval, the common service speed of high-altitude operation vehicle is slow, upper and lower ascend operation need to expend the plenty of time, cause current grounding switch bite work for the treatment of inefficiency, and ascend operation also exists the danger of falling from high altitude.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, without ascend operation, by two groups of pulley machinery transmissions, realize multi-angle adjusting operation bar head and pull open function to adapt to the grounding switch bite of different setting angles, increase work efficiency, reduce operating risk, the grounding switch bite handling implement guaranteeing personal safety.
The technical solution of the utility model is as follows:
A kind of grounding switch bite handling implement, under insulating bar, half outer surface is hinged with first group of pulley, strutting piece one end is fixedly connected with insulating bar head by nut, action bars head is hinged by the first jointed shaft and strutting piece middle part, second group of pulley central exterior surface is fixedly connected with the strutting piece other end, spring one end is hinged by the second jointed shaft and second group of pulley tail end, the spring other end is fixedly connected with action bars head top tip part, insulating cord one end is successively through second group of pulley, after first group of pulley again bind on the lock ring of second group of pulley head outer surface.
As preferably, under insulating bar, half outer surface fixed cover is equipped with retainer ring, and first group of pulley and retainer ring outer surface are hinged.
As preferably, action bars head is sickle type crotch parts.
The beneficial effects of the utility model are as follows:
This experiment is novel can save manually exerting oneself of half by two groups of pulley machinery transmissions.The utility model is simple in structure, easy to use, without ascend operation, by two groups of pulley machinery transmissions, realize multi-angle adjusting operation bar head and pull open function to adapt to the grounding switch bite of different setting angles, increase work efficiency, reduce operating risk, guarantee personal safety.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model;
In figure: the 1st, insulating bar, the 2nd, retainer ring, 3 is first group of pulley, the 4th, strutting piece, the 5th, nut, the 6th, action bars head, 7 is first jointed shafts, 8 is second group of pulley, the 9th, lock ring, 10 second jointed shafts, the 11st, spring, the 12nd, insulating cord.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of grounding switch bite handling implement as shown in Figure 1,1 time half outer surface of insulating bar is hinged with first group of pulley, and in the present embodiment, 1 time half outer surface fixed cover of insulating bar is equipped with 2, the first groups of pulleys of retainer ring 3 and is hinged with retainer ring 2 outer surfaces.Strutting piece 4 one end are fixedly connected with insulating bar 1 head by nut 5, action bars head 6 is hinged with strutting piece 4 middle parts by the first jointed shaft 7, second group of pulley 8 central exterior surface is fixedly connected with strutting piece 4 other ends, spring 11 one end are hinged by the second jointed shaft 10 and second group of pulley 8 tail end, spring 11 other ends are fixedly connected with action bars head 6 tips, the crown, insulating cord 12 one end successively through after second group of pulley 8, first group of pulley 3 again bind on the lock ring 9 of second group of pulley 8 head outer surface.
This tests novel insulating bar 1, the long rope 12 of insulation is made for insulating material, and other parts are that metal material is made.This tests novel action bars head 6 for sickle type crotch parts.
During use, a staff lifts insulating bar 1 bottom, drop-down insulating cord 12 other ends of another staff, insulating cord 12 one end are by the drop-down second group of pulley 8 of lock ring 9, second group of pulley 8 be take as the mechanics strong point in insulating cord 12 middle parts simultaneously, produce and on double active force, draw spring 11, spring 11 by be pulled through in journey and drive action bars head 6 to turn clockwise around the first jointed shaft 7, until action bars head 6 crotches parts can be hooked grounding switch joint; Then the drop-down insulating bar of staff 1 bottom, partly pulls open grounding switch joint by action bars head 6 crotches.
Above-described embodiment is only for the utility model is described, and not with the restriction of the present utility model of opposing.So long as according to technical spirit of the present utility model, to above-described embodiment change, modification etc. all will drop in the scope of claim of the present utility model.
