Description
Technical field
The present invention relates to technical field of power systems, more particularly to a kind of Universal screw compression type ground wire operating lever.
Background technology
According to country and power industry associate power safety code regulation, when staff works on power equipment,
Possible power transmission must install three-phase shortcircuit ground wire to all directions of job site, and this is protection staff in job site
The reliable and secure measure sent a telegram here suddenly is prevented, while the residual charge of equipment breaking part, can also be drained because of ground connection.Existing skill
Art is that a conductor grip compressed with screw is fixed on insulating bar, and rotating insulated action bars drives screw to compress wire
（Remove the rotating insulated action bars of opposite direction）, in conductor grip connection annealed copper wire be fixed on earth clip earth point be grounded it is traditional thread binding
If.
But it is due to that power equipment is connected with wire and there is various ways in which, such as level connection joint, vertical connection, original ground wire
Conductor grip be fixation can not adjustment angle, on wire connected horizontally install ground wire when be easier, and will with ground
Face has larger angle just to seem especially difficult in particular perpendicular to when installing ground wire on the wire on ground, often will be by ascending a height
Instrument, such as stool, ladder even hoistable platform, while adding high-rise working risk again, could so complete ground wire
Installation.
The implementation of prior art is typically that conductor grip is fixed as 90 degree, and changing Impact direction using gear drive drives
Screw compresses wire, solves the problem of installing ground wire on wire perpendicular to the ground.
Because conductor grip is fixed on 90 degree, the installing of wired earth line perpendicular to the ground, other angle wires are only solved
Installing it is still highly difficult, and use meshed transmission gear, this must just use the higher metal material of hardness to make, and typically lead
Wire clamp uses aluminium alloy, gentlier, not only increases the weight of conductor grip, makes to hold operation high and adds difficulty, and increases
Manufacture and purchase cost.
The content of the invention
In view of the deficienciess of the prior art, it is a primary object of the present invention to provide a kind of conductor grip in the horizontal direction
360 degree, about 120 degree of vertical direction angle-adjustable and can reduce parking space and reduce the Universal screw pressure of cost
Compact form ground wire operating lever.
To achieve the above object, the invention provides following technical scheme：A kind of Universal screw compression type ground wire operation
In bar, including wire clip assembly, adjustment component, operation rod and the driving handle component being sequentially connected, the conductor grip
It is provided with the chuck that the screw being connected with universal joint and spiral compression bolt are connected with steel wire drive flexible axle, the adjustment component bag
Support tube is included, for permanent universal joint and steel wire drive flexible axle, the inserted sleeve for connecting insulating bar is additionally provided with
And spacing non-magnetic shim, the operation rod is including insulating bar and is arranged on inside insulating bar and soft with steel wire drive
Axle and the insulating driving rod of driving handle chuck connection, the screw-type that the driving handle component is provided for attended operation bar connect
Joint.
