The understanding of the disclosure of utility model is more thorough and comprehensive.
It should be noted that unless otherwise defined, all technical and scientific terms used in this specification with belong to
The normally understood meaning of those skilled in the art of the utility model is identical.In the used in the description of the utility model
Term be only for the purpose of describing specific embodiments be not intended to limitation the utility model.
With reference to the accompanying drawing, each embodiment of the utility model is described in detail.
Referring to Fig. 1, Fig. 1 is an example structure schematic diagram of the utility model segmental roof truss erection device.At this
In embodiment, including for placing fold-line-shaped room after segmental roof truss beam is demoulded righting and the Lift-on/Lift-off System sling and righting
The adjustable support 10 set a roof beam in place, Lift-on/Lift-off System include the first wirerope 1 for suspending the first fixed pulley 2 in midair, the second wirerope 3
By the first fixed pulley 1 and two rope end is connected respectively to the upper surface of 4 two ends of cross-arm, two ends of cross-arm 4
Lower end surface be separately connected the second fixed pulley 5 and third fixed pulley 6, third wirerope 7 is connected to broken line by the second fixed pulley 5
The left end of shape roof truss beam 9 is winded up, and the 4th wirerope 8 is connected to 9 right end of segmental roof truss beam by third fixed pulley 6 and winds up.
First wirerope 1 connects two parts, and upper end connection provides the crane of pulling force, and lower end connects the first fixed pulley 2；The
Two wirerope 3 are connected to cross-arm 4 by the first fixed pulley 2, and the setting of cross-arm 4 is the tension uniform in order to guarantee crane offer
Distribution, and for guaranteeing balance.
As can be seen that third wirerope 7 is connected to and winds up 91 both ends apart from left end at left end both ends on 91 of winding up
A quarter on chord length position, equally, the 4th wirerope 8 winds up in right end, and to be connected to distance right for the both ends on 92
Hold the position of chord length in a quarter at 92 both ends of winding up.Also, left end is winded up on two link positions and right end on 91
Two link positions on string 92 are symmetric.This structure setting may insure that pulling force effect is winded up 91 and right end to left end
Wind up 92 be it is balanced, can guarantee segmental roof truss beam 9 kept during righting balance.
Be placed on after 9 righting of segmental roof truss beam on adjustable support 10, the setting of adjustable support 10 be in order to
