[summary of the invention]
In view of this, for overcoming the deficiencies in the prior art, the present invention provides a kind of adjustable messenger unfolding jib, can either realize the overhead connection of the first messenger of crossing frame, can realize installing quickly and easily again.
For achieving the above object, the technical scheme of the present invention is as follows:
An adjustable messenger unfolding jib, comprises more piece rigidity arm joint, and each joint described rigidity arm joint is connected in turn by bolt head and the tail; More piece glass reinforced plastic arm saves, and adjacent two joints described glass reinforced plastic arm joint is connected by Connection Block; Wherein, adjacent described rigidity arm joint is connected by described Connection Block with described glass reinforced plastic arm joint.
Further, each joint described rigidity arm joint is the square-section that four main chords are welded with horizontal web member, oblique web member; Wherein each joint described rigidity arm joint is followed successively by from rear end forward end: the first variable cross-section arm joint, uniform cross section arm joint, band pulley uniform cross section arm joint and the 2nd variable cross-section arm joint.
Further, described first variable cross-section arm saves one end and is welded with even ear connecting plate; Described band pulley uniform cross section arm joint is welded with the pulley of arm joint lifting mechanism.
Further, each joint described glass reinforced plastic arm joint is the circular glass steel composition that four joint cross section diameters diminish successively from rear end forward end.
Further, described Connection Block is the pasting board of two the chain joint chairs matched, and the upper end of pasting board described in each is welded with two ear plates; The lower end of described pasting board is respectively welded with recessed and boss can cooperatively interacting.
On the other hand, the present invention also provides a kind of upright post of spanning frame, and described upright post of spanning frame is provided with adjustable messenger unfolding jib.
The invention has the beneficial effects as follows, it is compared to traditional crossing frame scheme, reduce workload, add working range, and just just can be realized the adjustment aerial at height of jib on ground by jib lifting mechanism and traversing mechanism, facilitate the working strength and the potential safety hazard that reduce operator with first messenger in aerial the docking of height; When jib is transferred, glass reinforced plastic arm joint can bend, and facilitates installation and the maintenance of jib, and provides convenient to the installation of first messenger.
