The object of the invention is by realize with under type:
The present invention includes lifting load-bearing hoop, tensioning governor motion, it is characterized in that: lifting load-bearing hoop by the straight plate of strip and be connected to straight plate two ends be an angle of 90 degrees with straight plate connecting bend is formed, connecting bend has axis hole, and on lifting load-bearing hoop, symmetry is provided with two pieces of lifting otic placodes; Lifting load-bearing hoop is the two pieces be arranged in parallel, between often pair of two pieces lifting load-bearing hoop relative connecting bend, connect a tensioning governor motion with shaft hinge.
Described tensioning governor motion is made up of the first shaft-like adjustment long nut, the first adjusting screw(rod), the second shaft-like adjustment long nut, the second adjusting screw(rod), band spacer pin, first shaft-like adjustment long nut is identical with the second shaft-like adjustment long nut structure, be all that one end is provided with screw socket, the other end is provided with axis hole; First adjusting screw(rod) is identical with the second adjusting screw(rod) structure, are all one end is the end of thread, and the other end is provided with limit pin hole; First adjusting screw(rod) and the first shaft-like adjustment long nut threaded engagement, the second adjusting screw(rod) and the second shaft-like adjustment long nut threaded engagement, the limit pin hole of the first adjusting screw(rod) and the second adjusting screw(rod) overlaps and uses band spacer pin to connect and compose tensioning governor motion.
Described first adjusting screw(rod) is that positive screw thread coordinates with the first shaft-like adjustment long nut, and the second adjusting screw(rod) is that anti-screw thread coordinates with the second shaft-like adjustment long nut.
Advantage of the present invention is: structure is simple, and easy to use, safe and reliable, applicability is strong; Go for the lifting of box-type section steel column and other H type and the prismatic steel column of cross steel column; Achieve lifting complete after automatically-unhooked, avoid the security risk of operating personnel's work high above the ground; In-site installation, convenient disassembly are flexible, improve the operating efficiency that steel column is installed, decrease artificial and mechanical consumption, reduce cost; Use can be cycled to repeat.
