Description

Device for attaching ropes to overhead wires

Technical field

The present invention relates to the technical field of electric power maintenance, and in particular to a device for climbing a pole-shaped body and for hanging a rope on an overhead line.

Background technique

When daily removing foreign objects on high-voltage lines, when the foreign objects are close to the operator, the insulated operating rod can be used to assist in the removal. However, when the foreign object is far away from the operator and cannot be removed using an insulating rod, the operator needs to throw the insulating rope. During operation, the operator first needs to climb the transmission tower and select an appropriate location. The location here should be determined according to the voltage level of the transmission line, 110KV It is 1.5 meters, 220KV is 3 meters, 330KV is 4 meters, and 500KV is 5 meters. Insulator strings are also connected at many locations. Tie a heavy object on one end of the insulating rope, throw the end of the wire with the foreign object hanging, and the underground workers will tie the two ends of the insulating rope. At the same time, the two ends move to the location of the foreign object, tie the "Crescent Fork" tool to the insulating rope, and pull the insulating rope to transfer it to the location of the foreign object. The underground staff continuously pulls the insulating rope, uses the "Crescent Fork" to wrap the foreign object, and finally removes it. Clear it from the wire.

However, because there are anti-vibration hammers installed on the side close to the transmission tower, it is difficult for the rope-throwing staff to send the rope to a position other than the anti-vibration hammer at one time. The rope is often stuck by the anti-vibration hammer, and it is necessary to find a way to remove the rope first. This operation This method prolongs the working time and increases the work intensity of the operator. Moreover, because the working position is high-altitude operation, the human body swings greatly when throwing the insulating rope, which seriously affects the personal safety of the operator. When the distance is short, the rope can be sent to the designated location by connecting multiple insulating rods, but when the distance is far away, the insulating rod connection is very long, and the rope and the weight connected to the rope are installed on the other end of the insulating rod. The operator's arm strength is very high.

The bracket 10 is detachably arranged on the cross arm 100 of the electric tower, and the cross arm 100 of the electric tower is perpendicular to the direction of the overhead wire 200 (it can be vertical in different planes). The telescopic mechanism 20 is placed transversely on the bracket 10 and can rotate on a plane perpendicular to its extension direction. The extension direction of the telescopic mechanism 20 is parallel to the direction of the overhead wire 200.

At this time, the telescopic mechanism 20 is parallel to the overhead wire 200 and a certain distance away from the overhead wire 200; the clamping mechanism 40 is switched to open. state, set the rope 400 in the clamping mechanism 40 and switch the clamping mechanism 40 to the closed state again. At this time, the rope 400 is held by the clamping mechanism 40; then, as shown in Figure 8, the telescopic mechanism 20 is extended. The length is as long as the rocker arm 30 can avoid obstacles after swinging (this application only takes avoiding the anti-vibration hammer 300 as an example); then, as shown in Figure 8, force is applied to rotate the telescopic mechanism 20, thereby causing the rocker arm 30 to rotate. The arm 30 rotates. When the rotation angle of the rocker arm 30 causes the rope 400 clamped by the clamping mechanism 40 to cross the overhead wire 200, the clamping mechanism 40 is controlled to switch to the open state. At this time, the rope 400 falls to hang on the overhead wire. On line 200.

The present invention uses the telescopic function of the telescopic mechanism 20 and the swing function of the rocker arm 30 to avoid obstacles and cross the overhead wire 200 with the rope 400, and the rope 400 is hung on the overhead wire 200 by opening the clamping mechanism 40.
