Abstract
The utility model discloses a cable clamp for fire welding during hot-line work. The cable clamp is characterized by comprising a fixed tip (1), wherein the fixed tip (1) consists of a fixed hook (1-1) and a fixed tip seat (1-2); the upper part of the fixed tip seat (1-2) is movably connected with a thread end pressure plate (3) through a fixed bolt (2); the lower part of the fixed tip seat (1-2) is in thread connection with a fastening screw rod (6); one end of the fastening screw rod (6) is connected with a fastening tip (5); and the other end of the fastening screw rod (6) is connected with a fastening bolt (4). The cable clamp is simple in structure, safe and reliable, is suitable for electrified fire welding of different types of distribution overhead lines, ensures that connecting leading wires of the overhead line are in an overhanging chain shape and droop naturally and has an attractive appearance; the fastening bolt (4) can be operated by either an ordinary spanner wrench or a socket wrench, or an insulating bar with tip, so that the electrified working efficiency is improved, and the safety of electrified work is ensured.
Description
Technical field:
The utility model relates to a kind of wire clamp, relates in particular to a kind ofly to be used for that the distribution overhead transmission line is a kind of to be used for the wire clamp that live line working is started to exchange fire.
Background technology:
The live line working of distribution overhead transmission line can not only avoid the user to have a power failure, and the activity duration is more flexible, along with social economy's improving constantly to the power supply reliability requirement, distribution line live working project and scope enlarge year by year, but in distribution overhead transmission line live line working work, the operating personnel is when charged installation branch line, originally be used to have a power failure the wiring wire clamp of operation when fixing branch line termination, not only inapplicable insulating bar live line working mode, and owing to have a power failure different with two kinds of operating types of live line working, former wiring wire clamp is in direct live line working process, fluctuation of service often comes off, and after former wiring wire clamp installs, also need to adjust branch line tip bend shape, increased the insecurity of live line working.Take place in order to change analogue, be badly in need of a kind of direct live line working usefulness of starting to exchange fire that both had been suitable for of development, be fit to the wire clamp of the charged effect of insulating bar again, to improve distribution live line working scope and efficient, guarantee equipment installment quality, guarantee the fail safe of distribution overhead transmission line live line working.
The utility model content:
The purpose of this utility model is that the deficiency that overcomes above-mentioned prior art provides a kind of simple in structure, safe and reliable, adjusting is flexible, installation is firm, applied widely, improve live line working efficient, guarantees the wire clamp that live line working is started to exchange fire that is used for of live line working fail safe.
The purpose of this utility model can reach by following measure: a kind ofly be used for the wire clamp that live line working is started to exchange fire, it is characterized in that it comprises fixedly termination, fixedly the termination is connected and composed by stay hook and stiff end headstock, the top of stiff end headstock flexibly connects the end of a thread pressing plate by set bolt, the lower thread of stiff end headstock connects fastening screw, one end of fastening screw connects fastening termination, and the other end connects fastening bolt.
The utility model can produce following good effect compared with the prior art: the utility model can be realized the insulating bar operation with belt end, the box spanner operation that also available use is common,
And the branch line lead ends does not need to adjust curved shape again, only needs by the end of a thread pressing plate and stiff end
The hook bolt connection is fixed, and it is sagging naturally to make it to realize that overhead transmission line connects the chain that goes between to become to dangle, and reduces the live line working time, improves live line working efficient, guarantees the live line working fail safe, the convenient and installation quality that assurance equipment is installed.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind ofly be used for the wire clamp (referring to Fig. 1) that live line working is started to exchange fire, make by copper material, it comprises fixedly termination 1, fixedly termination 1 is connected and composed by stay hook 1-1 and stiff end headstock 1-2, the top of stiff end headstock 1-2 flexibly connects the end of a thread pressing plate 3 by set bolt 2, the lower thread of stiff end headstock 1-2 connects fastening screw 6, and an end of fastening screw 6 connects fastening termination 5, and the other end connects fastening bolt 4.
During use, lead ends is pressed abd fixed between the end of a thread pressing plate 3 and the stiff end headstock 1-2 by set bolt 2, by insulating bar or employing direct operation method, the fixing stay hook 1-1 of termination 1 is hooked on the built on stilts alive circuit, and drive fastening screws 6 by rotation fastening bolt 4 fastening termination 5 and stay hook 1-1 are fixed on the built on stilts alive circuit, realize starting to exchange fire, overhead transmission line is connected go between to become to dangle chain sagging naturally, appearance looks elegant improves operating efficiency and fail safe.Both available common adjustable wrench of fastening bolt 4 or box spanner operation also can be used the insulating bar operation of belt end.
