Fixation is bolted in connection sheet and the second cable connection piece.
As shown in fig. 6, the shaft 1-5 is elongated cylindrical body.
As shown in fig. 7, offering the second through-hole 2-4, the second gib head 2-1 and second on the second coupler body 2-2
Coupler body 2-2 is rotatablely connected in the first logical hole 1-4 by the second through-hole 2-4 using shaft 1-5 as axis.On the clump weight 2-3
Offer the second connector 2-5, the second connector 2-5 shape be it is poroid, i.e. the second connector 2-5 be bundle hole, institute
The end for stating the second rope passes through bundle hole and links together with clump weight 2-3 binding.
As shown in figure 8, the shape of the latch hook is the mentioned ridge-shaped of M shape.
Operation instruction:
As shown in figure 9, operator stands in the tower bar above transfer wire 3 when overhauling to transmission line of electricity.Behaviour
Make personnel and hold the first rope and the second rope, the second rope is made to be in relaxation state.At this point, the gravity in clump weight 2-3 is made
Under, the lower section that latch hook rotates naturally and clump weight 2-3 is made to be located at ground connection hook, the second gib head 2-1 is located at the first logical hole 1-4
Interior, the first gib head 1-1 and the first coupler body 1-2 are in open state, and the first gib head 1-1 and the first coupler body 1-2 are caught on transmission and led
Line 3.
As shown in Figure 10, after the first gib head 1-1 and the first coupler body 1-2 catch on transfer wire 3, the first rope is above mentioned, is made
It must be grounded to hook and tightly catch on transfer wire 3.Then, above mention the second rope, under the traction of the second rope, clump weight 2-3 to
Upper rotation, the second gib head 2-1 are rotated down and are overlapped on transfer wire 3, and the second gib head 2-1 and the second coupler body 2-2 will be transmitted
Conducting wire 3 is locked in the ground connection hook that the first gib head 1-1 and the first coupler body 1-2 is formed.
After first rope and the second rope are bundled in tower bar and complete ground connection work, it can further start check man
Make.
As shown in figure 11, existing grounding technical solution, operator using be grounded pincers clamping transfer wire 3 when,
Earth cable is caught by ground connection pincers to the top for transferring to transfer wire 3, by the self gravity of ground connection pincers, suddenly downwards with hand
Release ground connection pincers, transfer wire 3 stir the bull stick 4 of ground connection pincers, and the jaw for being grounded pincers clamps transfer wire 3.
Technical problem of the existing technology is:
First, it operates more complicated, it is time-consuming and laborious, it is O&M low efficiency, at high cost.The discovery of practical operation scene, behaviour
It is frequently necessary to repeatedly discharge ground connection pincers downwards suddenly as personnel, the jaw that ground connection can just clamped clamps transfer wire 3.Cause this to ask
The reason of topic is that the eave tile of bull stick 4 is connected in the groove of jaw, there is clamping frictional force between eave tile and groove, works as transmission
When the impact force of conducting wire 3 and bull stick 4 is not enough to overcome the clamping frictional force, bull stick 4 not can rotate, and the jaw for being grounded pincers cannot press from both sides
Firmly transfer wire 3.
Second, it is easy to damage transfer wire 3, reduces 3 safety in utilization of transfer wire, reduces the use of transfer wire 3
Service life.
The technical program compared with prior art, operates convenient and simple, time saving and energy saving, and O&M is high-efficient, at low cost.
The discovery of practical operation on-site verification, operator only need once-through operation that can catch on transfer wire 3.
Since there is no shock, transfer wire 3 will not be damaged, 3 safety in utilization of transfer wire is improved, extends transmission
3 service life of conducting wire.
It is grounded hook and latch hook and 3 locking of transfer wire cooperates, it is safe to use.High altitude operation is frequently encountered air-flow
Even if the influence ground connection hook and latch hook of operation vibration are trembleed or are shaken on transfer wire 3, will not be with transfer wire
3 break off relations.However in the prior art, although ground connection pincers can clamp transfer wire 3, if ground connection pincers and transfer wire 3 one
It rises and trembling occurs or shakes, there are the security risks of unhook.
