Description
Technical field
The utility model belongs to electric power system repair apparatus field, is specifically related to a kind of device of limit phase insulator work operation of charged for replacement ZML type tower.
Background technology
For improving power supply reliability, after thunderbolt, bird pest etc. cause line insulator flashover, all need to change insulator in time, and ZML type tower does not have special, ripe band electric tool, the limit phase insulator work operation of this tower of charged for replacement is all very complicated, need adopt the modes such as equipotential work, difficulty is very large.Therefore, seldom adopt live line working always.After flashover situation appears in the insulator of this tower, generally adopt the mode having a power failure and change, cause circuit reliability to decline and security risk increases.According to live line working, new tool must be manufactured.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and the special cross-arm card of a kind of ZML type tower provided, and what it can make operating personnel's safety completes more changing jobs of ZML type tower limit phase insulator string with the working method of live line working.
The object of utility model is achieved in that
The special cross-arm card of a kind of ZML type tower, it comprises the first-hand handle component of left end and second-hand's handle component of right-hand member, fastener is provided with between two handle assemblies of left and right, first-hand handle component is connected with the first screw component in end, second-hand's handle component is connected with the second screw component in end, first screw component and the second screw component end be connected with the first coupler body and the second coupler body respectively, be provided with the 3rd coupler body at the middle part of fastener.
Described 3rd coupler body has 2, one end of the 3rd coupler body run through fastener and pass above fastener, the other end is coupler body shape.
Described first-hand handle component and second-hand's handle component are connected by screw and fastener and the first screw component, the second screw component.
Described first coupler body and the second coupler body are plate pulling hook, and the first screw component is connected with plate pulling hook by arm-tie joint in end with the second screw component.
The utility model achieves following technique effect:
Adopt said structure, operating personnel can complete more changing jobs of ZML type tower limit phase insulator string with live line working working method safely, efficiently, decrease the number of times of interruption maintenance, avoid the security risk adopting equipotential work, reduce labour intensity and the workload of operating personnel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
The special cross-arm card of a kind of ZML type tower as shown in Figure 1, it is characterized in that: it comprises the first-hand handle component 1 of left end and second-hand's handle component 2 of right-hand member, fastener 4 is provided with between two handle assemblies of left and right, first-hand handle component 1 is connected with the first screw component 3 in end, second-hand's handle component 2 is connected with the second screw component 5 in end, first screw component 3 and the second screw component 5 end be connected with the first coupler body 6 and the second coupler body 7 respectively, be provided with the 3rd coupler body 8 at the middle part of fastener 4.
Described 3rd coupler body 8 has 2, one end of the 3rd coupler body run through fastener 4 and pass above fastener, the other end is coupler body shape.
Described first-hand handle component 1 and second-hand's handle component 2 are connected by screw 9 and fastener 4 and the first screw component, the second screw component.
Described first coupler body 6 and the second coupler body 7 are plate pulling hook, and the first screw component is connected with plate pulling hook by arm-tie joint 10 in end with the second screw component.
When adopting said structure, first upper card is passed to electrician on tower by ground staff, on tower, electrician looks for an appropriate location mounting clip pieces 4 above the insulator string hanging point at cross-arm place, what make that on fastener 4 two the 3rd coupler bodies 8 all can be good withholds cross-arm tower material, and make fastener 4 both sides screw component be positioned at above the plumb line of transmission pressure, tighten dish shape nut 11 after installing and fastener 4 is installed firmly.
Then two cover plate pulling hooks, arm-tie, screw component, handle assembly are passed to electrician on tower after assembling, screw mandrel is installed on fastener 4 two ends by operating personnel on tower, is connected by screw fixing, and such cross-arm card installs.
Adjust the degree of tightening up of screw component again, make plate pulling hook all can hook transmission pressure and then synchronously tighten up two screw mandrels, and while tightening up screw mandrel, check the situation of each parts, continue to tighten up screw mandrel after confirmation is as good as, until the vertical load of insulator string is all transferred on jig, now just can take out insulator spring pin, old insulator is put down by transmitting rope, new insulator is installed, after replacing insulator completes, is completed the dismounting of jig by order contrary to the above.
