As shown in fig. 8, the latch hook is in the shape of an M-shaped ridge.
Description of use:
as shown in fig. 9, when the transmission line is overhauled, an operator stands on the tower above the transmission line 3. The operator holds the first rope and the second rope with the second rope in a relaxed state. At this time, under the gravity action of the balancing weight 2-3, the latch hook naturally rotates and enables the balancing weight 2-3 to be located below the grounding hook, the second hook head 2-1 is located in the first through hole 1-4, the first hook head 1-1 and the first hook body 1-2 are in an open state, and the first hook head 1-1 and the first hook body 1-2 hook the transmission wire 3.
After the first hook head 1-1 and the first hook body 1-2 hook the transmission wire 3, the first rope is lifted up so that the ground hook hooks the transmission wire 3 tightly, as shown in fig. 10. Then, the second rope is lifted up, the balancing weight 2-3 rotates upwards under the traction of the second rope, the second hook head 2-1 rotates downwards and is lapped on the transmission wire 3, and the transmission wire 3 is locked in the grounding hook formed by the first hook head 1-1 and the first hook body 1-2 by the second hook head 2-1 and the second hook body 2-2.
After the first rope and the second rope are bound on the tower pole and the grounding work is completed, the maintenance work can be further started.
As shown in fig. 11, in the conventional grounding treatment technical scheme, when an operator uses a grounding clamp to clamp a transmission wire 3, the operator uses the grounding clamp to clamp the grounding cable, and then downwards drops the grounding clamp above the transmission wire 3, and by means of self gravity of the grounding clamp, the grounding clamp is released downwards in a jerk manner, the transmission wire 3 dials a rotating rod 4 of the grounding clamp, and the jaw of the grounding clamp clamps the transmission wire 3.
The technical problems existing in the prior art are as follows:
firstly, the operation is relatively complex, time and labor are wasted, the operation and maintenance efficiency is low, and the cost is high. In practice, it has been found that the operator often needs to release the ground clamp down several times in order to cause the jaws of the ground clamp to grip the transmission line 3. The reason for this problem is that the hook of the rotating rod 4 is clamped in the groove of the jaw, clamping friction exists between the hook and the groove, and when the impact force of the transmission wire 3 and the rotating rod 4 is insufficient to overcome the clamping friction, the rotating rod 4 cannot rotate, and the jaw of the grounding clamp cannot clamp the transmission wire 3.
Secondly, the transmission wire 3 is easy to damage, so that the use safety of the transmission wire 3 is reduced, and the service life of the transmission wire 3 is prolonged.
Compared with the prior art, the technical scheme is convenient and simple to operate, time-saving and labor-saving, high in operation and maintenance efficiency and low in cost. The actual operation site verification shows that the operator can hook the transmission wire 3 only by one operation.
Because no impact exists, the transmission wire 3 is not damaged, the use safety of the transmission wire 3 is improved, and the service life of the transmission wire 3 is prolonged.
The grounding hook and the locking hook are in locking fit with the transmission wire 3, so that the use safety is high. The high-altitude operation can often meet the influence of air current or operation vibration, even if the grounding hook and the locking hook shake or shake on the transmission wire 3, the grounding hook and the locking hook can not be unhooked with the transmission wire 3. However, in the prior art, although the grounding clamp can clamp the transmission wire 3, if the grounding clamp and the transmission wire 3 shake or shake together, there is a safety hazard of unhooking.
