Description
Technical field
The utility model belongs to vertical wires earth terminal technical field, and in particular to one kind is grounded for vertical wires
Head.
Background technique
Traditional ground line is mostly to be directed to horizontal wire design, if in 110kV and above line voltage distribution mutual inductance
Work installing ground line on device and arrester, not only needs to carry ladder, need under normal conditions an other people help could incite somebody to action
This grounding wire mounting is set as function, if it is work of the 500kV route on outgoing line side voltage transformer and arrester, it is also necessary to by
Lift truck.One kind is developed for vertical wires earth terminal, grid switching operation people need to only stand rotates ground wire operating lever on the ground,
Ground wire can be installed successfully without ladder or lift truck.
Solve following problems:
1, traditional earth terminal is designed for horizontal wire, when installing ground line in vertical wires, tradition ground connection
Line is not applicable；
2, when installing is grounded in vertical wires, tradition ground line installing difficulty is time-consuming and laborious, influences equipment power failure inspection
Repair efficiency；
3, when installing ground line in vertical wires, the installing of tradition ground line need to use lift truck or special messenger is needed to assist to increase
Human cost and operational risk.
Summary of the invention
The technical issues of the utility model solves is: one kind be provided and is directed to vertical wires earth terminal, it is above-mentioned existing to solve
There is the problem of technology.
The technical solution that the utility model is taken are as follows: one kind is directed to vertical wires earth terminal, including lap joint, lap joint
The upper jacking block with handstand L-type hook portion and with hook portion cooperation, the long free end of hook portion is vertically fixedly connected on turbine and worm variable-speed motor
On the shell of structure, the output shaft of turbine and worm gear connects lead screw by screw, and lead screw both ends both pass through shell, and one end
It is rotatably connected on jacking block, the worm screw of turbine and worm gear is fixedly connected with operating stick, and worm screw and lead screw are kept
Vertically.
Preferably, it is fluted to correspond to holding position setting for above-mentioned hook portion and jacking block.
The utility model has the beneficial effects that compared with prior art, the utility model is pacified by turbine and worm gear
Mounted in overlap joint head-tail, the steering operation of lap joint is realized, convenient for the vertical overlap joint to vertical route, grid switching operation people only needs to stand
Ground wire operating lever is rotated on the ground, ground wire can be installed successfully without ladder or lift truck, and substitution tradition connects
Ground wire office can only hang the limitation of horizontal wire, not only shorten the overhaul of the equipments time, at the same reduce human cost and
The security risk of grid switching operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.

Limit, the worm screw 9 of turbine and worm gear 4 is fixedly connected with operating stick 10, and worm screw 9 keeps vertical with lead screw 5, the wiring
Head is mainly for the need of work installing ground line on 110kV and above line voltage transformer and arrester.
Turbine and worm gear 4 includes shell 8, worm screw 9 and turbine 7, and 9 both ends of worm screw are rotatably attached by bearing
On shell 8, turbine 7 is rotatably connected on shell 8 by output shaft 12, and turbine 7 and worm screw 9 are meshed, output shaft 12
For hollow structure, screw 6 is placed in output shaft fixed.
Preferably, above-mentioned hook portion 2 and the corresponding holding position setting fluted 11 of jacking block 3.
Jacking block 3 is provided with limited block close to the long free end side of hook portion 2, and limited block is embedded into the setting of the long free end of hook portion 2
In limiting slot, it is convenient for jacking block displacement.
Example above description is only a specific implementation of the present invention, the protection scope of the utility model not office
It is limited to this.Be familiar with the those skilled in the art within the technical scope disclosed by the utility model, can easily find variation or
Alternative, these should be covered within the scope of the utility model.For this purpose, the protection scope of the utility model should be with
Subject to the scope of protection of the claims.
