Description
Technical field
The utility model relates to a kind of strain insulator four insulator string string charged for replacement devices.
Background technology
Strain insulator four insulator string strings are exactly that four insulator string strings constitute a square, bear the insulation gold utensil syndeton form of a phase live wire: when wherein a string damage, when needing to change, difficulty is very big, the charged for replacement equipment that does not also have at present special-purpose replacing strain insulator four insulator string strings, general using is set up the conventional equipment of strain insulator four insulator string strings insulator string is changed in construction, there is following shortcoming in this equipment replacement insulator:
1, must the power failure operation.When utilizing spanning equipment in the background technology to change insulator, workmen and equipment can not the contact electrification leads, therefore, must the power failure operation, power consumer is stopped power supply, can cause unnecessary economic loss.
Even 2 charged for replacement also will be sling going up the whole string of insulator string, translation goes out original position, just can fall earthward and change, and this kind mode needs many with the workmen, and labour intensity is big, and the engineering time is long.
The utility model content
The equipment that the utility model has solved the replacing strain insulator four insulator string strings in the background technology must have a power failure operation, labour intensity is big and the engineering time is long technical problem.
Technical solution of the present utility model is: the utility model is a kind of strain insulator four insulator string string charged for replacement devices, its special character is: this device comprises anchoring knife-edge jig 2 and preceding anchoring turnover panel card 4, anchoring knife-edge jig 2 is provided with prong 8, preceding anchoring turnover panel card 4 comprises jig body 5 and turnover panel 6, turnover panel 6 two ends connect with jig body 5 activities respectively, and anchoring knife-edge jig 2 is connected with preceding anchoring turnover panel card 4 with insulated tension pole 3 by wire grip 1.
Above-mentioned turnover panel 6 one ends hang rotating shaft with jig body 5 by insulator string and are connected, and the other end connects for movable with jig body 5.
Above-mentioned turnover panel 6 is that clamping or bolt are connected with the movable connecting mode of 5 of jig body.
Said apparatus also is provided with bottle supporting frame 9, and bottle supporting frame 9 is arranged on insulated tension pole 3 belows.
Be provided with bracing frame 10 in the above-mentioned bottle supporting frame 9.
Above-mentioned bottle supporting frame 9 two ends are provided with bottle supporting frame hanger 11.
The utlity model has following advantage:
But 1 live line working.The utility model is in whole replacing process, and the workmen works under equipotential condition, and simultaneously, complete equipment is to adopt high-strength insulating material to make, and therefore, the utility model can be realized live line working, does not need power consumer is stopped power supply.
2, labour intensity is low, and the engineering time is short.The utility model is multiple functional, can realize that the whole string of insulator is changed or grouping is changed, and only needs two to three people to finish on the whole replacing process king-rod, and labour intensity is low, and the engineering time is short.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises anchoring knife-edge jig 2 and preceding anchoring turnover panel card 4, anchoring knife-edge jig 2 is provided with prong 8, preceding anchoring turnover panel card 4 comprises jig body 5 and turnover panel 6, turnover panel 6 two ends connect with jig body 5 activities respectively, anchoring knife-edge jig 2 is connected with preceding anchoring turnover panel card 4 with insulated tension pole 3 by wire grip 1, turnover panel 6 one ends hang rotating shaft with jig body 5 by insulator string and are connected, the other end connects for movable with jig body 5, turnover panel 6 and the movable connecting mode of 5 of jig body are that clamping or bolt are connected insulated tension pole 3 belows and are provided with bottle supporting frame 9, be provided with bracing frame 10 in the bottle supporting frame 9, can reduce bottle supporting frame 9 stressed backs and reduce sagging radian amount, guarantee that insulator string can take off string under minimum amount of contraction, bottle supporting frame 9 two ends are provided with bottle supporting frame hanger 11, bottle supporting frame hanger 11 is to utilize the hole in L shaped vertical yoke plate 7 and the square yoke plate 12 of F type to make fulcrum, hang the special-purpose framework of bottle supporting frame, it can hang the bottle supporting frame, also can adjust the height of bottle supporting frame, make it suitable installation.
During the utility model work, during a string on changing strain insulator four insulator string strings in two insulator strings, prong on the anchoring knife-edge jig 2 of the present utility model 8 is inserted solid in the hole of the L shaped vertical yoke plate 7 that hangs four insulator string strings, then on the insulator hanging scroll 13 of turnover panel 6 by preceding anchoring turnover panel card 4 with the square yoke plate 12 of preceding anchoring turnover panel card 4 hitch F types, after fixing, wire grip 1 connects insulated tension pole 3 and anchoring knife-edge jig 2, preceding anchoring turnover panel card 4 links to each other, so just constituted the stressed system of bypass of insulator string, the receipts of last insulator string pine and take off string, because bottle supporting frame 9 length very long (basic identical) with the porcelain vase string, sagging crooked radian distance and the weight in stressed back is directly proportional, grow up to quadratic relationship with string, therefore, increasing bracing frame 10 in the middle of the bottle supporting frame 9 is that insulator string is made fulcrum under utilizing, and bottle supporting frame 9 stressed length are reduced half.After last insulator string was thrown off, bottle supporting frame 9 was sagging under the effect of insulator string weight, can be supported on down on the insulator string, and bottle supporting frame 9 is level substantially like this, and it is convenient to take off string.
During a string under changing strain insulator four insulator string strings in two insulator strings, this moment, anchoring knife-edge jig 2 and preceding anchoring turnover panel card 4 were installed downwards, and bottle supporting frame 9 is contained in the top of wire grip 1 and insulated tension pole 3, and lifting ropes have been installed in bottle supporting frame 9 centres.Bottle supporting frame 9 is suspended on the insulator string, and pull is fastening, the weight of insulator string string is born by last insulator string string, like this, bottle supporting frame 9 is not crooked substantially sagging, utilizes the operational method that replaces with the insulator string string then, will descend insulator string to be changed.
