Description
Technical field
The present invention relates to power circuitry engineering fields, more particularly, to a kind of block crossing frame of two sides docking.
Background technique
With China's rapid development of economy, national power load increasingly increases, and needs to set up enough power transmission lines
Road meets power demand, and the erection space of transmission line of electricity is limited, and which results in transmission line of electricity scissors crossing phenomenon hair
Raw is more and more frequent, and power cut construction will cause massive losses, and existing crossing construction, which mostly uses, to be lived across.Electric transmission line hot-line
Crossing construction refers in the case where not influencing crossed line charging operation, using set up the realization of insulating protection facility create it is defeated
The stringing of electric line works.Across posture across a kind of form of construction work for being electric transmission line hot-line leap, this mode is to exist first
Crossing frame has been set up in crossed line two sides, then hangs over block device in crossing frame, forms mesh font block, finally will be new
It builds transmission line wire and carries out tension stringing.Across posture cross over compared to it is other live across mode have group cube just, account for
Therefore small, the applied widely advantage of ground area is of great significance to the research of crossing frame.
The patent application text of Publication No. " CN107394678A " discloses a kind of telescopic arm block crossing frame, the leap
Frame realizes the aerial docking of crossing frame by telescopic arm and docking facilities.But since block lever system is installed on telescopic arm,
It is in the state shunk before completing docking, so the object that is spanned below needing in docking carries out power down process.While by
The multiple movements stretched out and docking facilities are docked are carried out in telescopic arm, the activity duration can be extended, and lead to power failure
Time also extends.
Summary of the invention
The present invention is to overcome the problems, such as that power off time when docking of crossing frame described in the above-mentioned prior art is long, provides one
Kind block crossing frame disposably realizes quickly complete block in the case where not having a power failure above crossed line.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of block crossing frame of two sides docking, packet
