Abstract
The utility model discloses an improved portable grounding wire. A clamping head has a structure as follows: an upper clamping plate, a lower clamping plate and a right vertical plate form a clamping head opening; a movable clamping plate is arranged in the clamping head opening; and the clamping head opening is fixed on an insulating rod. An L-shaped support arm is fixed on the insulating rod, a movable adjusting arm is hinged on the L-shaped support rod; and inward concave arc surfaces are respectively and correspondingly arranged at the top surface of the movable clamping plate and the bottom surface of the upper clamping plate. Due to the inward concave arc surfaces between the upper clamping plate and the movable clamping plate, an oval opening is formed to thereby firmly clamp a wire nose of a round wire or a panel row. The improved portable grounding wire disclosed by the utility model has the advantages of good clamping function and wider application range.
Description
Technical field
The utility model relates to portable earth connection, and particularly 10KV portable field hanging earthing conductor is used earth connection.
Background technology
The on-the-spot hanging earthing conductor of operation power operating personnel finds that existing portable earth connection chuck is difficult for clamping to the round wire nose, thereby forms potential safety hazard.The chuck opening of existing portable earth connection is less than normal, causes the inconvenience in the use.
The utility model content
The purpose of the utility model provides a kind of portable earth connection of modified model with reliable clamping action.
This novel purpose is achieved in that the portable earth connection of a kind of modified model, and comprise chuck: form the chuck opening by train wheel bridge, lower plate and right riser, moving clamping plate are arranged in this chuck opening, and this chuck opening is fixed on the insulating bar; Be fixed with L shaped support arm on the insulating bar, be hinged with movable regulating arm on the L shaped support arm, the corresponding respectively indent arcwall face that is provided with on said moving clamping plate end face and the train wheel bridge bottom surface.
The spacing of above-mentioned train wheel bridge bottom surface and lower plate end face is 80mm.
The depth of the chuck opening that above-mentioned train wheel bridge, lower plate and right riser surrounded is 95mm.
Compared with prior art, the utility model beneficial effect is:
1, clamping action is better: owing to the indent arcwall face between train wheel bridge and the moving clamping plate forms ellipse or circular folder mouth, therefore, can securely the round wire nose or the dull and stereotyped busbar of ground wire be clamped, thereby improve the reliability of ground connection, guarantee job safety.
2, increase the chuck opening size, adaptive surface is wider: as, the aperture pitch between the upper and lower clamping plate increases 47mm on the original basis.And for example, the opening that upper and lower clamping plate and right riser surrounded (about for opening) depth increases 38mm on the original basis.
The utility model is particularly useful as the portable earth connection of 10KV.
Description of drawings
Fig. 1 is the structure chart of existing portable earth connection.
Fig. 2 is the structure chart of this portable earth connection.
Embodiment
Fig. 2 illustrates, and this new type chuck structure is: form the chuck opening by train wheel bridge 1, lower plate 3 and right riser 4, moving clamping plate 2 are arranged in this chuck opening, and this chuck opening is fixed on the insulating bar 7; Be fixed with L shaped support arm 5 on the insulating bar 7, be hinged with movable regulating arm 6 on the L shaped support arm 5, the corresponding respectively indent arcwall face (move clamping plate and be fixed on the telescopic mast, spring is arranged on the telescopic mast) that is provided with on moving clamping plate 2 end faces and train wheel bridge 1 bottom surface.The spacing of train wheel bridge 1 bottom surface and lower plate 3 end faces is 80mm (increasing 47mm on the original basis).The depth of the chuck opening that train wheel bridge 1, lower plate 3 and right riser 4 are surrounded is 95mm (increasing 38mm on the original basis).Among Fig. 2, on the right riser (or claim in frame) two of Φ 6mm earth studs are arranged.
