Utility model content
Technical problem to be solved in the utility model is to provide a kind of earth connection, the angle between duck-beak type shock wire clamp and telescopic insulation rod can be changed as required, handled easily person stands on shaft tower and hangs ground wire binding clip, improve and earth connection efficiency is installed, have the advantages that structure is simple, easy and simple to handle and guarantee is safe.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of earth connection, comprises telescopic insulation rod, duck-beak type clashes into wire clamp, ground connection annealed copper wire and ground clamp; Described ground connection annealed copper wire is through the endoporus of telescopic insulation rod, and its left end and duck-beak type clash into wire clamp and be connected, and right-hand member is connected with ground clamp, and described duck-beak type clashes into wire clamp by hinged between connector and the left end of telescopic insulation rod, and is provided with retaining mechanism; The left part of described ground connection annealed copper wire is stretched out a bending section from telescopic insulation rod left end endoporus and is clashed into wire clamp with duck-beak type and be connected.Described connector is U-shaped left side brace and U-shaped right side brace; The openend of described U-shaped left side brace clashes into wire clamp by bolt and duck-beak type and is fixedly connected with, the end face of U-shaped left side brace is connected with the end face of U-shaped right side brace, the openend of described U-shaped right side brace is bolt and nut thereof by hinged between bolt and telescopic insulation rod left end, described retaining mechanism.
Preferably, the end face of described U-shaped left side brace and the end face of U-shaped right side brace are riveted by bolt.
Preferably, the end face of described U-shaped left side brace and the end face of U-shaped right side brace pass through rivet.
The utility model is further improved and is: described telescopic insulation rod is provided with reflective vitta and spaced apart.
The beneficial effect that technique scheme produces is:
One, the utility model is by the angle between adjustment U-shaped right side brace and telescopic insulation rod, the hanging ground-wire tie point of different angles can be adapted to, especially handled easily person stands on tower bar and carries out hanging ground-wire operation to the vertical lead wire of overhead, eliminate the risk that when operating personnel hangs earth connection, health significantly tilts, can safety be ensured, avoid personal injury, raise labour efficiency.
Two, this earth connection, by the length of adjustment insulating telescopic bar, can meet the requirement of different distance when hanging earth connection, make easy and simple to handle.
Three, telescopic insulation rod is provided with reflecting at night vitta, facilitates when insufficient light or night-time observation ground wire installment state.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of angle adjustment between U-shaped right side brace and telescopic insulation rod;
Fig. 3 is the schematic perspective view that the end face of U-shaped left side brace is connected with the end face of U-shaped right side brace.
As shown in the figure: 1 duck-beak type clashes into wire clamp, brace, 4 telescopic insulation rod, 5 reflective vittas, 6 ground connection annealed copper wires, 7 bolts, 8 bending sections, 9 ground clamps on the right side of brace, 3U type on the left of 2U type.
