Description

Circuit obstacle crossing type driving
Technical field
The invention belongs to high-altitude power transmission lines overhauling field of tool, and in particular to a kind of circuit obstacle crossing type driving.
Background technology
Work in the ground wire of transmission line of electricity is because apart from shaft tower, farther out, personnel are difficult to reach the position that need to be overhauled, institute To need to use driving.Driving is a kind of vehicles that work high above the ground personnel take in ground wire, and its effect is by high-altitude Operating personnel is transported to the place for needing to overhaul, and returns after hours.Double bundle conductor being used existing 110KV-220KV more, There are the facilities such as conductor spacer, stockbridge damper, wire clamp and conductor anti-galloping inter-phase spacer in circuit, if necessary to above-mentioned Circuit is overhauled, the defect that there is the following aspects:
(1)Due to there is conductor spacer, stockbridge damper, wire clamp and conductor anti-galloping inter-phase spacer between ground wire Deng facility, so as to cause driving can not be normal through, traditional driving through above-mentioned obstacle in order to carry out operation, it is necessary to one One dismounting climbs over these facilities, causes the activity duration to greatly prolong, and expend the muscle power of operating personnel.
(2)It can also be overhauled using the method for throwing over barrier, but easily occur high-altitude pendant in throwing over barrier Fall, jeopardize personal safety.
(3)When running into Novel spacer, because new-type conductor spacer needs just to can be removably mounted with specific purpose tool, dismounting work can be given It is difficult to recover to bring after difficulty, and the dismounting of conductor anti-galloping inter-phase spacer, to natively cumbersome operation procedure The cumbersome degree of increase.
(4)Traditional unmanned inspection robot, uses unmanned control mostly, and staff can not take and closely see Examine line condition.
At present, although such as CN102941570B also has obstacle crossing function more than conventional circuit barrier-surpassing robot, it can cross over Barrier on wire, but this obstacle detouring structure is more complicated, operating process inconvenience, bearing capacity is inadequate, it is impossible to carry out manned work Industry, and carry and in-convenience in use, it is therefore desirable to design the stronger circuit obstacle crossing type driving of usability, meet line maintenance Need.
The content of the invention
