Technical field
The utility model relates to a kind of wire support device, particularly a kind of for the wire support device of support belt electric lead when insulator on 10kV charged for replacement bar.
Background technology
Live line working belongs to work high above the ground, need to step on bar or carry out operation by aerial lift device with insulated arm.In the time of shaft tower top insulator generation defect, need the charged insulator that renews.Because power cable is being supported in insulator top, after cable need to being removed, could change, and cable is with high-tension electricity, can not be pulled down rear being directly placed on cross-arm, otherwise can there is ground fault, cable need to be lifted, more finish changing after insulator, then power cable is fixed on new insulator.Replacing insulator under electrified has generally been coordinated by many people now, by stepping on bar or taking aerial lift device with insulated arm, after several operating personnels prop up the cable that loses support, changes insulator by an other staff, after replacing insulator completes, then cable is fixed.When the cable arrangements more complicated on wire pole tower or the working space rate of exchange are when narrow, cannot realize many people's operations, give and change insulator and bring very large inconvenience.
utility model content
According to above the deficiencies in the prior art, the purpose of this utility model is: a kind of wire support device is provided, in the time changing insulator, charged wire can be propped up, convenient operation, uses flexibly, reduces operating personnel's quantity and task difficulty, increases work efficiency.
Wire support device described in the utility model, comprise plate shape base, two insulating support rods and rotation axis, one anchor ear is arranged on base, two insulating support rods are separately positioned on base two ends, its middle part is connected by bearing pin with base, and a roller is installed in insulating support rod upper end, and its lower end is threaded with rotation axis, rotation axis is provided with transmission case, and one handle is connected with transmission case.
Can be by the cross-arm of the fixing online bar of base by anchor ear, fixation is reliable, makes base play good supporting role, insulating support rod upper end contacts with wire by roller, can reduce the frictional force in moving process by roller, convenient mobile, avoid damaging wire simultaneously.Insulating support rod can rotate around middle hinging pin shaft, by the rotation of rotation axis, make the lower end of insulating support rod inwardly shrink or outwards open, thereby drive insulating support rod upper end to swing, reach the object that regulates insulating support rod height, by being rotatably connected on the handle on transmission case, realize the rotation of rotation axis, easy to operate.
In described transmission case, be provided with the first helical gear being arranged on rotation axis, the second helical gear and the bearing assembly that engage with the first helical gear, the second helical gear is arranged on arm pivot post end, turning handle, drives the first helical gear to rotate by the second helical gear, thereby drives rotation axis to rotate.
The first described helical gear is mutually vertical with the second helical gear center of rotation, realizes break-in, facilitates the rotating operation of handle.
The first described helical gear and the second helical gear are helical gears, and engagement property is good, and stable drive, noise are little, and registration is large, has reduced the load of every pair of gear, has improved the bearing capacity of gear.
Described rotation axis two ends thread rotary orientation is contrary, makes the insulating support rod of both sides inwardly shrink simultaneously or outwards open, and realizes the consistency regulating.
Described base is provided with bar-shaped trough and a through hole, anchor ear one end is arranged on through hole by nut, and the other end is fixed on bar-shaped trough by nut, the width of the adjustable anchor ear of bar-shaped trough, by selecting the anchor ear of different size, can meet the installation requirement of different cross-arms.
When 10kV replacing insulator under electrified, first operating personnel is fixed on cross-arm top by the utility model by anchor ear, and make roller in cable below, then drive rotation axis to rotate by swinging handle, insulating support rod is slowly shunk, until wire support is arrived to correct position, then just can carry out dismounting to insulator.
Compared with prior art, the beneficial effect the utlity model has is:
The Placement Problems of power cable when the utility model can effectively solve the built on stilts replacing insulator under electrified of 10kV, the quality of guarantee live line working, reduces operating personnel's quantity and task difficulty, increases work efficiency; The roller of insulating supporting boom end can effectively reduce the frictional force in insulating support rod operating process and between power cable, compared with less wear; By handle is set, make in operating process more laborsaving.
