Description

Throwable ground clamp

technical field

The utility model relates to a ground wire clip, in particular to a throw-and-hang type ground wire clip.

Background technique

The installation of grounding wire is an important technical measure to ensure the safety of electricity and the safety of operators. At present, when installing the throwing grounding wire, the staff stands on the cross arm of the tower, and places the grounding wire clamp vertically downwards above the wire, so that the grounding wire clamp clamps the wire, so that the wire is grounded. Personnel climbed up the tower to remove the clamp. However, when the angle of the pole tower is large, the tension resistance angle is large, and the distance between the pick-up line and the pole tower is far away, the distance between the operator's operation and control is not enough, and the grounding wire clamp cannot be vertically corresponding to the wire, making the installation of the grounding wire clamp difficult, and often requires the staff to climb on the porcelain bottle Series grounding is time-consuming and labor-intensive, and it is dangerous for staff to stand on a high place and throw it, which is likely to cause safety accidents.

The second clip fits.

The utility model has the advantages that: in the utility model, by setting the torsion spring between the two insulating ropes at both ends of the clip and the clip, the staff can fix one insulating rope and hold the other on one side of the wire. An insulating rope, throw the grounding wire over the other side of the wire, and then tighten the other insulating rope to fix the two clips on the wire, avoid vertical installation, and prevent the grounding wire from being damaged due to the large angle of the tower and the large tension rotation angle. The clip is not easy to install and other problems occur. The utility model also has the advantages of simple and compact structure, low manufacturing cost and easy use.

Detailed ways

The throwing-type grounding clip, as shown in Figure 1, includes a first clip 1 and a second clip 2, and arc-shaped bayonets 3 are provided on the opposite surfaces of the first clip 1 and the second clip 2, The two mounts 3 correspond to each other. The first clip 1 and the second clip 2 can clamp the wire by closing the bayonet 3 . A fixed shaft 4 is arranged between the first clip 1 and the second clip 2, and a pair of connecting plates 5 are installed on the first clip 1 and the second clip 2, and both pairs of connecting plates 5 are hinged with the fixed shaft 4, A torsion spring 6 is arranged between a pair of connecting plates 5 inside, and the torsion spring 6 is installed on the fixed shaft 4, and the torsion spring 6 always pushes the first clip 1 and the second clip 2 outward. Both the first clamp piece 1 and the second clamp piece 2 rear ends are equipped with connecting ropes 7, the first fixed piece 8 is connected between the two connecting ropes 7, the first fixed piece 8 is connected with the first insulating rope 9, and the first clamping piece 1, the connecting piece 10 and the second fixing piece 13 are installed, the first clamping piece 1 is provided with the first connecting bolt 11, the first clamping piece 1 is connected with the connecting piece 10 and the second fixing piece 13 through the first connecting bolt 11, connected The ground wire 12 is connected to the piece 10 , and the second insulating rope 14 is connected to the second fixing piece 13 . This structure allows the staff to fix one insulating rope, hold another insulating rope on one side of the conductor, throw the grounding wire 12 over the other side of the conductor, and then pull the other insulating rope to tighten the two clips. Fix it on the wire, avoid vertical installation, and prevent problems such as the difficulty of installing the grounding clamp due to the large angle of the tower and the large rotation angle of the tension.

When installing the grounding wire, first fix the first insulating rope 9 on the ground, then the staff climbs up the pole tower, holds the second insulating rope 14 on one side of the wire, throws the grounding wire 12 over the other side of the wire, and quickly tightens the second The insulating rope 14 makes the first clamping piece 1 and the second clamping piece 2 open, and the wire is stuck at the bayonet 2, and continues to tighten the second insulating rope 14, so that the first clamping piece 1 and the second clamping piece 2 can overcome the torsion. The thrust of the spring 6 closes the first clip 1 and the second clip 2, and the closed bayonet 3 clamps the wire, so that the grounding wire 12 is hung on the wire. When dismounting, the second insulating rope 14 is fixed on the ground, the first insulating rope 9 is tightened, the first clip 1 and the second clip 2 are opened, and the wire is separated from the bayonet 2, so that the grounding wire 12 is separated from the wire. At this time, the first clamping piece 1 and the second clamping piece 2 are closed and reset under the elastic force of the torsion spring 6 .

In order to prevent the first connecting bolt 11 from being tightly connected to the first clip 1 , the connecting piece 10 and the grounding wire 12 are rotated around the first connecting bolt 11 , so that the grounding wire 12 is detached from the wire. The connecting piece 10 is further provided with a second connecting bolt 15 , and the connecting piece 10 is connected with the first clamping piece 1 through the second connecting bolt 15 . This structure enables two connection points between the connecting piece 10 and the first clamping piece 1 , preventing the connecting piece 10 and the ground wire 12 from rotating around the first connecting bolt 11 .

In order to avoid excessive tension of the insulating rope, the openings of the first clip 1 and the second clip 2 are too large, and the torsion spring 6 is compressed and deformed due to excessive force, thereby reducing the service life of the torsion spring 6 . The connecting shaft 17 is installed in the middle part of the first clip 1, and the stop plate 18 is hinged on the connecting shaft 17. The middle part of the second clip 2 is provided with a connecting groove 16, and the free end of the limiting plate 18 stretches out from the connecting groove 16, and the limit One side of the free end of the plate 18 defines an arc-shaped locking groove 19 , and the locking groove 19 cooperates with the second clip 2 . This structure limits the opening range of the first clamping piece 1 and the second clamping piece 2, so as to avoid the shortened service life of the torsion spring 6 caused by compression deformation caused by excessive force.

The technical solution of the utility model is not limited within the scope of the embodiments described in the utility model. The technical contents not described in detail in the utility model are all known technologies.
