Description
Technical field
The present invention relates to ultra-high-tension power transmission line repair and maintenance technical field, especially relate to a kind of machine for lifting earth wire of ultrahigh-tension power transmission line.
Background technology
In recent years, because climate change is to damage to crops caused by thunder, windburn that ultra-high-tension power transmission line caused, and situation such as incident outside destroy causes all generations again and again of high-voltage power line conductive ground wire damage accident in the urban development construction.Because overhead ground wire is positioned at the superiors of whole ultra-high-tension power transmission line, thereby repair and during the optical cable reparation overhauls, often need pitch and promote ground wire in lead wire and earth wire; In addition, ground wire also can be done the aerial slideway of other conducting wire mendings.Therefore, ground wire pitches, enhancing rate increases thereupon.But, in line maintenance, pitch significantly and the mode that promotes ground wire rests on the traditional handicraft always.
Mainly there is following problem in traditional handicraft: 1, in the ultra-high-tension power transmission line maintenance, influence that ground wire pitches and to promote uncertainty a lot, its ground wire pitches and the distance that promotes is the scope of repairing according to the lead needs and content and fixed, but, existing instrument range of lift of the same type has only about 300mm, can not satisfy the line maintenance job requirement; 2, line maintenance operating environment complexity uses the short instrument of existing range of lift to promote, complicated operation and all need secondary operation mostly, and cost of overhaul height not only, and also labour intensity is big; 3, because in the design of stringing shaft tower, all be subjected to pressure and Horizontal Tension vertically downward on the cross-arm of fixing cord, and pitch and promote in the ground line process in traditional handicraft, most of tool bearing forces situation all can not satisfy above-mentioned vertical stressed requirement in the shaft tower design; 4, along with shaft tower double loop and multiloop employing, cross-arm constantly extends thereupon, and manpower is shouldered and lifted and can't launch; 5, poor stability, existing instrument of the same type is repaiied in the lifting process at lead, mostly be that nature hangs, thereby in its use, very easily skid off the cross-arm head, and not, do not take the corresponding backup protection measure that prevents wire dropping simultaneously now at the corresponding backup protection measure that skids off behind the cross-arm head yet; 6, because the hand of not hesitating of instrument, thereby manpower increases, and expense strengthens and safety can't guarantee that simultaneously, the controllability to institute's tool using in line maintenance is not strong; 7, operational method is lack of standardization, and nonstandard operating type directly has influence on the popularization of standardized work.In a word, the existing tool stroke that promotes ground wire is shorter, and can not solve long distance and dynamic ground wire pitch and promote in the problem that exists.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency of the prior art, a kind of machine for lifting earth wire of ultrahigh-tension power transmission line is provided, it is simple in structure and use easy and simple to handle, reduced labour intensity, can effectively solve long distance and dynamic ground wire pitch and promote in existing problem.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of machine for lifting earth wire of ultrahigh-tension power transmission line, it is characterized in that: comprise base on the cross-arm head that is installed in stringing tower bar top, be installed in the external support frame on the base and be installed in the external support frame and coaster that can in the vertical direction freely rotate, described coaster is a discoid roller and along the circumferential direction is provided with the groove that moves for the single rope of insulation on it that described base is provided with securing member.
Described external support frame and coaster are connected and fixed to screw rod by the level of passing the two, and screw rod passes from the center of coaster, between screw rod and coaster bearing are installed.
