Description
Technical field
The utility model belongs to overhead transmission line maintenance field, and in particular to the aerial ground wire lifter of one kind.
Background technology
Make somebody a mere figurehead ground wire and be also known as lightning conducter, the electric current for thunder and lightning to be produced introduces the earth, to prevent thunder and lightning generation
Electric current destroys transmission facility.In much time using, due to for clamping aerial ground wire and being suspended in aerial ground wire
The wire clamp in high-altitude can gradually relax, so in the case of not using good wire clamp locking measures, aerial ground wire can be with
Wire clamp misplaces.When aerial ground wire misplaces with wire clamp, the supporting point of aerial ground wire can change, and aerial ground wire can also
With wire clamp phase mutual friction.If things go on like this, the internal structure that aerial ground wire can be made more fragile is damaged, or even can make to make somebody a mere figurehead
Ground wire disconnects.Therefore, it is necessary to aerial ground wire is overhauled.
At present, it is in all parts of the country all to carry out replacement inspection using various indigenous methods because without handy service kit
Repair, due to being hotline maintenance, the requirement for instrument is very stringent, once the reason for instrument occur occurs accident, will cause serious
Consequence.

Fig. 2 is this lifter side structure cut-away illustration；
Wherein, housing 1, stay hook 11, opening 12, helical gear 2, shaft 3, rocking bar 31, open slot 32, J-type bar 4, locking
Piece 5.
Embodiment
Elaborate below in conjunction with specific embodiment to the utility model.
As shown in Figure 1 and Figure 2, the present embodiment includes housing 1, and the top of housing 1 is equipped with stay hook 11, and stay hook 11 is used for
This lifter is hooked and is fixed on power grid tower head.
Both sides in housing 1 are equipped with helical gear 2, and the top of helical gear 2 is equipped with shaft 3, the side wall at 3 both ends of shaft be equipped with
The diagonal pitch that helical gear 2 engages, shaft 3 are crossed-axes gear drive with helical gear 2, and helical gear 2 is driven by groove when shaft 3 rotates
Rotate.For the ease of rotating shaft 3, rocking bar 31 is equipped with the both ends of shaft 3, the convenient shaft 3 of shaking of rocking bar 31 rotates, the rocking bar
31 can with the hands shake at the same time, rotating Vortex, and operation is very easy and laborsaving.
J-type bar 4 is further included, J-type bar 4 is used to hook aerial ground wire, and J-type bar 4 runs through housing 1 vertically, and J-type bar 4 erects
Straight portion is equipped with the diagonal pitch engaged with helical gear 2, and J-type bar 4 is parallel drive with helical gear 2, and helical gear 2 can drive J when rotating
Type bar 4 moves up and down.
It should be noted that when the diagonal pitch set by the side wall at 3 both ends of shaft is in the same direction, two skew backs of the drive of shaft 3
Gear 2 rotates in same direction, therefore the J-type bar 4 of both sides must be respectively arranged on to the homonymy of both sides helical gear 2, so just can guarantee that both sides
The J-type bars 4 of both sides when rotating in same direction of helical gear 2 can be ibid with；Likewise, when the helical teeth set by the side wall at 3 both ends of shaft
When line is anti-phase, the 2 anti-phase rotation of both sides helical gear of the drive of shaft 3, therefore the J-type bar 4 of both sides must be respectively arranged on two skew backs
The offside of gear 2, the J-type bar 4 of both sides can be ibid with when so just can guarantee that the 2 anti-phase rotation of helical gear of both sides.
Preferably, the locking device of shaft 3 is further included, for locking shaft 3, prevents it from arbitrarily rotating.It is further excellent
Change, the locking device includes the lock sheet 5 of L-type, and one end of lock sheet 5 is hinged on before housing 1, is set before housing 1
There is an opening 12,3 side wall of shaft is equipped with open slot 32, and the axis of the other end of lock sheet 5 around hinged place is rotated and can inserted by opening 12
Into open slot 32.When needing to lock shaft 3, lock sheet 5 only need to be rotated to insertion opening groove 32, it is easy to use.
Preferably, housing 1, rocking bar 31 and J-type bar 4 are isolation material, and for security consideration, isolation material can be avoided effectively
The generation of electric shock accidents.
Preferably, the width of helical gear 2 is not less than the sum of the diameter of shaft 3 and the width of J-type bar 4, and this set can have
Effect ensures forced area during transmission, improves the security performance and service life of this lifter.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
