Background technology
In transmission line power failure maintenance activity process, for preventing unexpected incoming call in not clear situation, the life security that threatens operating personnel, need to hang earth connection conventionally.Power transmission lines overhauling, first carries earth connection by staff and steps on bar, then by hanging mutually; Though now circuit is in power down mode, in order to prevent unexpected generation, safeguard work personnel's personal safety, avoids coming to harm, and when hanging earth connection, human body should avoid touching earth connection.
In prior art, earth connection lacks reliable special isolation device, and in site operation process, earth connection is stepped on bar by workmen and carried, and when by phase hanging wire, human body is difficult to avoid touching earth connection, has great potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of earth connection with protection rope, to overcome defect of the prior art, effectively guarantees that staff, when circuit interruption maintenance is stepped on bar hanging earthing conductor, avoids Body contact earth connection.
The technical solution of the utility model is: comprise earth connection, ground connection pricker; Also comprise ground wire fixture block, be linked with, hook, bolt and three standard trolleies;
Ground wire fixture block middle part longitudinally has threading via hole, and ground wire fixture block sidepiece laterally has positioning screw hole, and positioning screw hole and threading via hole vertical connection, be equipped with bolt in positioning screw hole;
Ground wire fixture block sidepiece is also provided with suspension ring; Be linked with one end and connect suspension ring, the other end is connected with hook;
Standard trolley is comprised of wire-hanging hook and insulating bar, and wire-hanging hook is fixedly mounted on insulating bar upper end; The upper end of three-phase ground line is connected with the wire-hanging hook of each standard trolley respectively, and the through hole through ground wire fixture block is converged in three earth connection stage casings, and by bolt locking positioning, the lower end of earth connection is connected with ground connection pricker.
Further, the arc opening of described wire-hanging hook coupler body inner side is hingedly connected with wire clamp arm by bearing pin, and wire clamp arm is equipped with back-moving spring.
The utility model has the advantages that: simple in structure, easy for installation, the insulating bar of standard trolley adopts high-strength insulating material to make, while using the construction of the utility model hanging wire, staff first utilizes hook and is linked with hangings such as earth connection, standard trolleies on the cross-arm of shaft tower, away from human body after stepping on bar, hold respectively again and hold insulating bar by phase hanging wire, effectively avoid staff in operating process, to touch earth connection, eliminated hidden danger, guaranteed personal safety.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model ground wire fixture block and earth connection.
Embodiment
In figure: 1, ground wire fixture block, 2, suspension ring, 3, be linked with, 4, hook, 5, earth connection, 6, insulating bar, 7, ground connection pricker, 8, wire-hanging hook, 9, wire clamp arm, 10, bolt.
Embodiment
From Fig. 1～Fig. 2, the utility model comprises earth connection 5, ground connection pricker 7; Also comprise ground wire fixture block 1, be linked with 3, hook 4, bolt 10 and three standard trolleies;
Ground wire fixture block 1 middle part longitudinally has threading via hole, and ground wire fixture block 1 sidepiece laterally has positioning screw hole, and positioning screw hole and threading via hole vertical connection, be equipped with bolt 10 in positioning screw hole;
Ground wire fixture block 1 sidepiece is also provided with suspension ring 2; Be linked with 3 one end and connect suspension ring 2, the other end is connected with hook 4;
Standard trolley is comprised of wire-hanging hook 8 and insulating bar 6, and wire-hanging hook 8 is fixedly mounted on insulating bar 6 upper ends; Arc opening one side of wire-hanging hook 8 coupler bodies is equipped with bearing pin, and wire clamp arm 9 is assemblied on bearing pin, and wire clamp arm 9 is positioned at coupler body arc opening inner side and inwardly swings; Wire clamp arm 9 is equipped with back-moving spring, makes wire clamp arm lean coupler body in closure state under non operating state;
Article three, the upper end of (being three-phase) earth connection is connected with the wire-hanging hook 8 of each standard trolley end by bolt respectively, article three, earth connection stage casing is passed by the through hole of ground wire fixture block 1 after converging, and by bolt 10 locking positionings, the lower end of earth connection 5 and ground connection pricker 7 are welded to connect.
While carrying out power transmission lines overhauling, workmen steps on after bar, first hook 4 is hung on the cross-arm of shaft tower, utilize link up with, be linked with, ground wire fixture block etc. is suspended in earth connection 5, standard trolley on cross-arm girder steel, and human body and earth connection 5 are kept a safe distance; Then by the earth connection that is connected, its mode of operation is: the insulating bar 6 of hand-held standard trolley, with wire-hanging hook 8, hook transmission pressure and the insulating bar 6 of pulling back, and the wire clamp arm 9 in wire-hanging hook 8 openings swings and opens to the inside, under the effect of back-moving spring, compresses wire; Oppositely promote insulating bar 6, wire is skidded off in coupler body and wire clamp arm 9, take off standard trolley.In connecting the process of each phase conductor, because earth connection hanging is on cross-arm, away from staff's health, has avoided staff to touch unintentionally the accidents such as earth connection, circuit be charged and damaged.
