The present invention is mainly aimed at the fact that it is difficult and time-consuming to hang the clamp of the ground wire end of the existing insulated overhead ground wire, and the diameter of the ground wire is small. If it flows into the ground in time, it may cause harm to the maintenance personnel. It is difficult to provide a hanging method that can ensure a tight connection with the insulated overhead ground wire. Set up time, reduce the physical strength of the operators, and ensure the installation of firm and reliable insulated overhead ground wire ground wire wire end clamps

Embodiment 1
[0023] Such as figure 1 , 2 . As shown in 3, a chuck for the wire end of an insulated overhead ground wire grounding wire includes an insulating operating rod 1, one end of the insulating operating rod 1 is connected with a quick-insert fitting 2, and the end of the quick-insulating fitting 2 far away from the insulating operating rod 1 is locked. A quick plug 3 is connected, and the inner wall of the quick-insert fittings 2 is provided with a card slot 12, and the outer wall of the quick plug 3 is provided with a spring ball 13 matched with the card slot 12, and the spring ball 13 is an existing snap-in structure , used with the card slot 12 on the inner wall of the quick-insert hardware 2, when the quick-plug 3 is inserted into the quick-insert hardware 2, the spring ball 13 will snap into the card slot 12, thereby realizing the connection between the two, for the quick-plug 3 and The quick-plug fitting 2 acts on the opposite force to separate the two. The cross-section of ...

The invention relates to the field of electric power operation and maintenance auxiliary equipment, in particular to an insulated overhead ground wire ground wire lead end chuck. The insulated overhead ground wire ground wire lead end chuck comprises an insulating operating rod, one end of the insulating operating rod is connected with a quick-plug fitting, one end of the quick-plug fitting far away from the insulating operating rod is clamped with a quick plug, one end of the quick plug far away from the quick-plug fitting is provided with a lifting screw, and the lifting screw is in threaded connection with a lifting nut. The lifting nut is connected with a connecting plate through a lifting rod, the connecting plate is provided with a wire clamping bolt used for fixing the annealed copper wire, one end, far away from the quick plug, of the lifting screw is provided with a wire clamping head which is integrally conical, and the connecting plate is provided with a clamping opening which is matched with the wire clamping head and used for clamping the insulated overhead ground wire. According to the invention, tight connection with the insulated overhead ground wire can be ensured, and the insulated operating rod can be easily separated from the hanging fitting after hanging is completed, so that the hanging time is shortened.
Description
technical field [0001] The invention relates to the field of electric power operation and maintenance auxiliary equipment, in particular to an insulating overhead ground wire ground wire lead end chuck. Background technique [0002] With the rapid development of power transmission and transformation in my country, the construction process is becoming more and more standardized, scientific and technical, and the equipment used is also becoming more and more advanced. With the continuous development of electric power technology and the continuous improvement of social demand for power supply safety and stability, safe operation is becoming more and more important to various electric power enterprises. [0003] Insulated overhead ground wires sometimes have defects such as damage and loose strands. Because they are not connected to the earth, when they are overhauled, they need to be hung with ground wires to prevent damage to maintenance personnel by induced electricity. [0...
