For making the purpose of this utility model, technical scheme and advantage clearly understand, also with reference to accompanying drawing, the utility model is further described below in conjunction with specific embodiment.
Each embodiment of the present utility model proposes a kind of frame structure and patrols and examines electric aerodyne (can be called driving for short), can more conveniently patrol and examine and upkeep operation ultra-high-tension power transmission line safely.
According to the embodiment of one side of the present utility model, provide a kind of frame structure, for the electric aerodyne of patrolling and examining of patrolling and examining along high-voltage power line conductive line is installed to wire, comprising:
Be in the matrix below wire;
Two upper arms, each upper arm is installed to described matrix with lower end and extends up to the top of wire with upper end, upper arm described at least one is the movable upper arm being hingedly installed to described matrix with its lower end, make described two upper arms relative to each other can rotate and be in closed configuration or open configuration, under described closed configuration, the roller of patrolling and examining electric aerodyne described in the mutual locking of described two upper arms maintenance makes is in place on two parallel wires respectively by the upper end of described upper arm;
Hang connector, it is pivotally mounted to described matrix and to downward-extension.
Like this, when driving is placed on wire (such as two parallel wires) by needs, (namely two upper arms open, the lower end that they are installed to matrix remains unchanged, and their free upper end is separated from each other, form the angular range region of opening), make two corresponding wires be in the region between two upper arms; Then, (namely two upper arms close up, their angle reduces, between the lower part of preferably two upper arms, angle can be decreased to zero, that is, the lower part of two upper arms is parallel to each other) wire is enclosed in the inner space surrounded between two upper arms, and mutually lock to be held in place by locking mechanism, in this case, the roller installation in position on these two wires respectively of two walking mechanisms of the free upper end of these two upper arms is arranged on respectively.By this design, easily driving can be placed on wire or from wire and pull down; By locking mechanism, two upper arms being in closed configuration are locked mutually, guarantee to run on wire in the inner space that roller surrounds all the time between two upper arms, thus make driving stable and reliable operation.Thus, can more conveniently safely ultra-high-tension power transmission line be patrolled and examined and upkeep operation.
Should be understood that when two described walking mechanisms are run respectively on two parallel wires, described " two parallel wire ", both can be two substantially contour wires, also can be two wires with difference in height.
