Fixed pulley 250, is correspondingly arranged multiple movable pulley 310 in each fixed pulley 250, bottom lifting rope 300 one end is connected between layer and puts down
Face frame body 200, what the other end was spaced successively is connected between layer plane support body through movable pulley 310, fixed pulley 250 and end
200, and suspension centre is located in the same horizontal plane.
Concrete, intermediate layer plane support body 200 is the support body of rectangle, in other embodiments, puts down to alleviate intermediate layer
The weight of face frame body 200, intermediate layer plane support body 200 can be tower structure, or I-shaped structure, intermediate layer plane support body
Outside 200 relative to both sides at least one fixed pulley 250 is installed, can need to install 2-4 according to design in other embodiments
Fixed pulley 250, simultaneously corresponding in the lower section of fixed pulley 250 is provided with multiple movable pulley 310, in the present embodiment, movable pulley 310
More than the quantity of fixed pulley 250 one of quantity, as it is shown in figure 1, bottom lifting rope 300 is through after a movable pulley 310, corresponding
Through a fixed pulley 250, being then passed through a movable pulley 310, by that analogy, last end is connected between layer plane support body 200,
Being provided with suspension centre on movable pulley 310, this suspension centre can be the similar lifting device such as suspension hook, suspension ring.
In the present embodiment, during lifting plate object, when the suspension centre on movable pulley 310 mounts plate object respectively, plate object
Relative both sides the most corresponding connect the movable pulley 310 below the corresponding photograph album of intermediate layer plane support body 200.Make movable pulley
310 and fixed pulley 250 autobalance load, plate object can remain parallel state during this truss is walked.Especially
It is when hoisting prefabricated floorboard, and Prefabricated construction panel can be lifted into presetting position, be directly connected to Prefabricated construction panel with
Lou Ti, it is not necessary to readjust the position of Prefabricated construction panel.
In the present embodiment, four edges of intermediate layer plane support body 200 are respectively equipped with a top suspension centre 240, top
One end of portion's lifting rope is connected to top suspension centre 240, and the other end of four top lifting ropes connects same top suspension hook 110, permissible
Understanding, the length of four top lifting ropes is identical, when by lifting machine pull-up top suspension hook 110, and intermediate layer plane support body
200 symmetric shapes centered by it, intermediate layer plane rack can keep the state of level.
In the present embodiment, intermediate layer plane support body 200 includes two intermediate layer crossbeams 210 and and two intermediate layer longerons
220, intermediate layer crossbeam 210 and intermediate layer longeron 220 head and the tail connect the tower structure forming rectangle, and fixed pulley 250 is arranged on
Intermediate layer crossbeam 210.It addition, installation intermediate layer internal stay corresponding between two intermediate layer crossbeams 210 in intermediate layer crossbeam 210
Beam 230, intermediate layer internal stay beam 230 plays the effect strengthening intermediate layer plane support body 200 rigidity, and makes intermediate layer plane support body
200 structures are more stable.
As shown in Figure 4, intermediate layer crossbeam 210 has the horizontal guide groove offered along intermediate layer crossbeam 210 bearing of trend
211;Fixed pulley 250 has connection assembly, connects assembly and embeds horizontal guide groove 211, and fixed pulley 250 can be driven along laterally leading
Groove 211 slides.In the present embodiment, the horizontal guide groove 211 that intermediate layer crossbeam 210 is offered embeds and connects assembly, connect assembly
Fixed pulley 250 can be driven to slide in horizontal guide groove 211.Before using this truss, the position of adjustable fixed pulley 250.The most every
Three fixed pulleys 250 are installed on individual intermediate layer crossbeam 210, can be according to the center of plate object, by two fixed pulley 250 correspondences
Walking is to the other end near intermediate layer crossbeam 210, and a remaining fixed pulley 250 walking is near intermediate layer crossbeam 210
The other end.Corresponding movable pulley 310 is positioned at the lower section of adjacent two fixed pulleys 250, and the position adjusting fixed pulley 250 can correspondence
The position adjusting movable pulley 310, can the position of suspension centre.When making this truss lifting plate object, plate object is when the state of lifting
More stable.
As it is shown in figure 5, intermediate layer longeron 220 has the longitudinal guide groove offered along intermediate layer longeron 220 bearing of trend
221, and longitudinal guide groove 221 connects with horizontal guide groove 211, connects assembly and fixed pulley 250 walking can be driven to longitudinal direction guide groove 221.
