Abstract
The utility model discloses a ground wire apparatus, which is used as a tool for maintaining a power transmission line. The ground wire apparatus comprises a grounding needle, ground wires and a wire hanging rod. The upper part of the grounding needle is provided with a horizontal wiring board. The wiring board, a wire hanging hook of the wire hanging rod, and jointing clamps on the two ends of the ground wires are all provided with two corresponding bolt holes. The jointing clamps are connected with the wire hanging hook and the wiring board respectively through two bolts. The jointing clamps, the wiring board and the wire hanging hook will not be loosened. The ground wire apparatus is thus connected in a firm and reliable way. Excellent grounding can be guaranteed. Potential safety hazards are further prevented.
Description
Technical field
The utility model relates to a kind of utensil using while overhauling transmission line, a kind of by the device of wire ground connection specifically.
Background technology
When transmission line keeps in repair, need to be by transmission line ground connection after the power-off of operating a switch.During ground connection, be generally that a steel or copper grounding pin are driven underground, with the standard trolley that a upper end band hanging wire hooks, hang on power transmission line, grounding pin and hanging wire are connected with the flexible conductor (being called earth connection) of copper or aluminium between hooking.Grounding pin, hanging wire arrange the terminal block in a strap bolt hole on hooking, the two ends of earth connection are fixedly connected with binding clip, and general of the connection that earth connection and grounding pin, hanging wire hook hooks fixing with a bolt by binding clip and grounding pin, hanging wire.But in use,, earth connection and grounding pin junction often can be become flexible, and cause bad connection, so just cause potential safety hazard.When finding loosening problem, staff just twists several buttons, bolt is tightened, but also can produce after a while loosening at present.
Utility model content
The utility model technical issues that need to address are to provide a kind of be connected firmly, ground wire grounding device that can guarantee good earth.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of grounding wire device, comprise grounding pin, earth connection and standard trolley, one horizontal terminal block is set on the top of grounding pin, two bolts hole are set on terminal block, the hanging wire of standard trolley also arranges two bolts hole on hooking, two bolts hole are respectively set on the binding clip at earth connection two ends, and all in correspondence with each other, what binding clip hooked with the hanging wire of terminal block on grounding pin, standard trolley is connected all with two bolts connections for the position of these bolts hole and size.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is: the hanging wire that the utility model connects the binding clip of earth connections and the terminal block on grounding pin, standard trolley by two bolts hooks, binding clip can not be rotated around bolt, binding clip and terminal block, hanging wire hook with regard to not producing loosening, thereby make earthing device firm and reliable connection, can guarantee good earth.Reduced because the fixing earth connection of single double-screw bolt becomes flexible, to staff, made troubles, stopped hidden danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, grounding pin, 2, terminal block, 3, bolt, 4, earth connection, 5, insulating bar, 6, binding clip, 7, hanging wire hooks.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
, comprising grounding pin 1, earth connection 4 and standard trolley, standard trolley comprises that a hanging wire of being made by conductor material hooks 7 and one insulating bar, is provided with the card wire clamp of two tongues in the hook that hanging wire hooks.One terminal block 2 is set on the top of grounding pin 1, and terminal block 2 transverse weld are on grounding pin.Two bolts hole are set on terminal block 2, the hanging wire of standard trolley hooks on 7 two bolts hole is also set, two bolts hole are respectively set on the binding clip 6 at earth connection 4 two ends, the position of these bolts hole and size are all in correspondence with each other, binding clip 6 and the hanging wire of terminal block 2 on grounding pin 1, standard trolley hook 7 be connected all and connect with two bolts, the binding clip 6 at earth connection 4 two ends can exchange be arranged on grounding pin 1 or hanging wire hook 7 on.
