Abstract
The utility model discloses a conveniently removed ground wire, which comprises a ground wire hook, wherein a baffle and a pull wire are arranged inside the ground wire hook; the pull wire passes through the hook and a pull ring is arranged on the other edge of the hook; and a spring is arranged between the baffle and the inner side of the ground wire hook. In the ground wire, a wire is clamped in the ground wire hook through the spring, and the contact surface of the baffle and the wire is cambered, so that the wire can be clamped well; when the ground wire is removed, the pull ring is pulled by using an insulating rod, the distance between the baffle and the ground wire hook is increased through pulling force of the pull wire and retraction of the spring, the ground hook can be separated from the wire by using small force, personnel do not need to climb on a pole, and the ground wire can be directly removed by using the insulating rod on ground; and thus, labor can be saved, operation can be facilitated, and the ground wire can be removed with less time, within one minute.
Description
Technical field
The utility model relates to a kind of earth connection of just removing.
Background technology
In power line construction, after the line outage, need carry out electrical verification and make safety measure, earth connection promptly is installed, guarantee that circuit and the earth are connected, and ensure workmen's personal safety.After line work finishes, need remove earth connection, put and can send after line insulation is qualified.
Owing to circuit work peace arranges place (dress ground line position) and construction location scarcely in same place, after causing line construction to finish, the workmen need step on bar again and remove ground wire, the one, strengthen workmen's workload, the 2nd, removing ground wire needs 10-15 branch clock time, cause interruption duration to prolong, influence power supply reliability.
The utility model content
The technical problems to be solved in the utility model provides a kind of convenient earth connection of removing.
The technical solution of the utility model is: just remove earth connection, comprise the earth connection hook, be provided with baffle plate and wire drawing in earth connection hook inboard, wire drawing is passed hook and is established draw ring at the another side of hook, is provided with spring between baffle plate and the earth connection hook inboard.
The contact-making surface of described baffle plate and lead is an arc.
Described spring housing is located in the wire drawing.
Described spring is two, evenly is located at around the wire drawing.
The beneficial effects of the utility model are: by spring with wire clamp in earth connection hook, the contact-making surface of baffle plate and lead is an arc, better clamping wire, when removing earth connection, use insulating bar pulling draw ring, by the wire drawing pulling force, the spring withdrawal makes distance increase between baffle plate and ground connection hook, with less power the ground connection hook is separated with lead, personnel need not step on bar, directly can remove earth connection with insulating bar on the ground, not only save manpower, and easy to operate, time spent is less, in 1 minute.
Description of drawings
Fig. 1 is the schematic diagram of embodiment 1;
Fig. 2 is the schematic diagram of embodiment 2.
Embodiment
Just remove earth connection, comprise earth connection hook 1, be provided with baffle plate 5 and wire drawing 2 in earth connection hook inboard, wire drawing 2 is passed the earth connection hook and is established draw ring 3 at the another side of earth connection hook, baffle plate 5 and earth connection are linked up with and are provided with spring 4 between 1 inboard, spring 4 is set in the wire drawing 2, and baffle plate 5 is an arc with the contact-making surface of lead.
Just remove earth connection, comprise earth connection hook 1, be provided with baffle plate 5 and wire drawing 2 in earth connection hook inboard, wire drawing 2 is passed the earth connection hook and is established draw ring 3 at the another side of earth connection hook, baffle plate 5 and earth connection are linked up with and are provided with spring 4 between 1 inboard, spring 4 is two, evenly is located at around the wire drawing 2, and baffle plate 5 is an arc with the contact-making surface of lead.
The utility model increases by a draw ring at the ground connection hook, the centre links to each other with baffle plate by wire drawing, between baffle plate and ground connection hook elastic force apparatus is arranged, when earth connection is installed under the spring force effect, baffle plate and ground connection hook pitch smaller, block lead and play the effect of dead earth line, prevent that simultaneously the ground connection hook from sliding.The use insulating bar holds ground connection hook draw ring when removing ground wire, and by draw ring wire drawing pulling force, the spring withdrawal makes distance increase between baffle plate and ground connection hook, with less power the ground connection hook is separated with lead, reaches and removes the ground wire purpose.
Claims (4)
