Abstract
The utility model discloses a backup protection device for a power transmission line. When a hand lever hoist falls due to force majeure factors, the backup protection device can pull a lead at the moment the strain section lead drops, thereby ensuring the safety of the strain section lead and the pole tower. The backup protection device comprises a wedge-shaped wire clamp, a locking device and a steel wire rope, wherein the wedge-shaped wire clamp comprises a wedge-shaped outer shell and a wedge-shaped sliding block which is arranged in the wedge-shaped outer shell, a rectangular sliding groove is arranged in the wedge-shaped sliding block, a fixed projection on the wedge-shaped outer shell is arranged in the rectangular sliding groove and limits the wedge-shaped sliding block through a spring; the locking device is formed by a wedge-shaped clamping device and a wedge-shaped clamping head; and one end of the steel wire rope is fixed at the head part of the wedge-shaped clamping head, and the other end of the steel wire rope is threaded in a cavity of the wedge-shaped outer shell and passes through the cavity of the wedge-shaped outer shell after bypassing the end surface of the wedge-shaped sliding block, and then penetrates the wedge-shaped clamping device.
Description
Technical field
The utility model relates to the protection safety device of operation on transmission line, maintenance in a kind of electric power system, relates in particular to a kind of transmission line backup protection equipment.
Background technology
At transmission line, carrying out insulator adjusts while climbing; generally use backup protection rope as second protection security tool; its effect be when tangle that the lever hoist of wire comes off or stripped thread after hold wire and drop from shaft tower to prevent wire, thereby guarantee the safety of this strain section wire and shaft tower.But adjust and climb in insulator work in reality; backup protection rope is the steel wire cable of regular length; its length tends to than the long 0.8-1.2 rice of insulator structure height left and right; when this comes off with regard to the lever hoist that irresistible factor is caused; the wire 1 meter of left and right of dropping to I haven't seen you for ages just can be backlogged protection rope and holds; the disconnected thigh of steel reinforced aluminium conductor aluminium lamination that likely can cause the distortion of overhead line structures cross-arm, backup protection rope, even operating personnel is injured.
Utility model content
For the deficiencies in the prior art; technical problem to be solved in the utility model is to provide a kind of transmission line backup protection equipment; when the lever hoist of irresistible factor initiation comes off; at drop moment this backup protection equipment of strain section wire, can hold described wire, guarantee the safety of this strain section wire and shaft tower.
The utility model adopts the basic conception of technical scheme to be: a kind of transmission line backup protection equipment, comprise wedge clamp, locking device and steel wire rope thereof, described wedge clamp comprises wedge-shaped enclosure and is placed in the wedge block of this wedge-shaped enclosure, the built-in rectangle chute of this wedge block, the fixed projection in described wedge-shaped enclosure is placed in rectangle chute and by spring, described wedge block is played to position-limiting action; Described locking device is comprised of Wedge gripping and the templin chuck being placed in one; One of described steel wire rope be fixed on templin chuck head, the other end of this steel wire rope penetrates after wedge-shaped enclosure cavity is walked around wedge block end face and passes from this wedge-shaped enclosure cavity, and passes from Wedge gripping.
Preferably, described wedge block end face is semi-circular recesses, and this groove is provided with ball, so that described steel cable sliding.
The beneficial effects of the utility model are, during use, the other end of steel wire rope is fixed on after passing from Wedge gripping on strain section wire, wedge-shaped enclosure head is connected to overhead line structures cross-arm by steel wire rope, when the lever hoist of irresistible factor initiation comes off, wedge block against the force of the spring down sliding, in wedge-shaped enclosure cavity, steel wire rope is clamped, simultaneously, Wedge gripping and the templin chuck being placed in one will also be clamped through steel wire rope wherein, like this, whole steel wire rope can not move thereby cannot elongate, in strain section wire moment of dropping, can hold described wire, guarantee the safety of this strain section wire and shaft tower, also guaranteed operating personnel's safety simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of wedge clamp, and Fig. 2 is the structural representation of locking device, and Fig. 3 is the scheme of installation of transmission line backup protection equipment.
In figure: 1-wedge-shaped enclosure; 2-wedge block; 3-rectangle chute; 4-fixed projection; 5-spring; 6-Wedge gripping; 7-templin chuck; 8-cross arm of tower; 9-wire; 10-steel wire rope I; 11-steel wire rope II.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, wedge clamp comprises wedge-shaped enclosure 1 and is placed in the wedge block 2 of this wedge-shaped enclosure cavity, the built-in rectangle chute 3 of wedge block 2, fixed projection 4 in wedge-shaped enclosure 1 is placed in rectangle chute 3 and by spring 52 position-limiting actions of wedge block, under external force, wedge block 2 can overcome spring 5 resistance down slidings and make the gap smaller of wedge block 2 and wedge-shaped enclosure cavity, can clamp through steel wire rope II11; Locking device is comprised of Wedge gripping 6 and the templin chuck 7 being placed in one, and under external force, Wedge gripping 6 and templin chuck 7 couplings become tight, make to be jammed through the steel wire rope II11 of Wedge gripping 6; One of steel wire rope II11 be fixed on templin chuck 7 head, its other end penetrates after wedge-shaped enclosure cavity is walked around wedge block end face and passes from this wedge-shaped enclosure cavity, and passes from Wedge gripping 6.
During use, the other end of steel wire rope II11 is fixed on strain section wire 9 after passing from Wedge gripping 6, wedge-shaped enclosure 1 head is connected to cross arm of tower 8 by steel wire rope I10, when the lever hoist of irresistible factor initiation comes off, wedge block 2 overcomes spring 5 resistance down slidings, in wedge-shaped enclosure cavity, steel wire rope II11 is clamped, simultaneously, Wedge gripping 6 and the templin chuck 7 being placed in one will also be clamped through steel wire rope II11 wherein, like this, whole steel wire rope II11 can not move thereby cannot elongate, in strain section wire 9 moment of dropping, can hold this section lead 9, guarantee the safety of wire 9 and shaft tower, also guaranteed operating personnel's safety simultaneously.
Wedge block end face is semi-circular recesses, and this groove is provided with ball, so that steel wire rope II11 slides to adjust its length with adaptive insulator structure height.
