Detailed Description
The invention is explained in further detail below with reference to the figures and the embodiments.
As shown in fig. 1-6, a lifting scaffold connecting device, including connecting cylinder 1, sleeve groove 2, fore-set groove 3, thread groove 4, fan-shaped groove 5, kicking block 6, scarf 7, preloading device 8, the utility model discloses by upper and lower, preceding, back, left and right six looks isostructure's connecting cylinder 1 integrated into one piece, it has sleeve groove 2 and fore-set groove 3 to open respectively in the connecting cylinder 1, sleeve groove 2 pegs graft with the support cylinder of scaffold, it has thread groove 4 to open in the 3 bottoms of fore-set groove, 1 outer wall of connecting cylinder is opened there are two and the communicating fan-shaped groove 5 of thread groove 4, fan-shaped contained angle of fan-shaped groove 5 is 90, four kicking blocks 6 of equal angle are installed to the circumference between sleeve groove 2 and the fore-set groove 3, opening of kicking block 6 has scarf 7, 1 central connection of connecting cylinder has preloading device 8.
The top block 6 moves in the radial direction of the connecting cylinder 1.
The pre-tightening device 8 comprises a screw rod 9, a cone frustum 10 and a rotating handle 11, the screw rod 9 is in threaded connection with the thread groove 4, the cone frustum 10 is integrally formed at the outer end of the screw rod 9, the outer wall of the cone frustum 10 is in sliding connection along the oblique cutting surface 7 of the top block 6, the outer wall of the screw rod 9 is vertically fixed with two rotating handles 11, and the rotating handles 11 rotate in the range of the sector groove 5.
