Accompanying drawing explanation
Fig. 1 is the structural representation of suspender in one embodiment of the invention;
Fig. 2 is the diagram of circuit of the using method of suspender in another embodiment of the present invention.
The specific embodiment
Core concept of the present invention is; on the main hoisting frame of suspender, slide block is set; with slide block, drive pipe link to move; the suspension centre of suspender can be moved; with this, will adjust suspension centre to the center of gravity line of member to be hung; thereby guarantee member in lifting and process in place steadily, reach protection member Hoisting Security, improve the object of lifting efficiency.
The suspender and the using method thereof that the present invention are proposed below in conjunction with the drawings and specific embodiments are described in further detail.According to the following describes and claims, advantages and features of the invention will be clearer.It should be noted that, accompanying drawing all adopts very the form of simplifying and all uses non-ratio accurately, only in order to convenient, the object of the aid illustration embodiment of the present invention lucidly.
As shown in Figure 1, the suspender 100 of one embodiment of the invention comprises main hoisting frame 1, pipe link 2, a slide block 3, a screw rod 4 and two clamp nuts 5.Wherein, one end of pipe link 2 is connected with slide block 3, slide block 3 is positioned on main hoisting frame 1, and can on main hoisting frame 1, move, by slide block 3, slide and can drive institute's pipe link 2 laterally to slide along main hoisting frame 1, the other end of pipe link 2 is connected with lifting equipment, and screw rod 4 runs through slide block 3 and is fixedly connected with slide block 3,5 two ends that lay respectively at screw rod 4 of two clamp nuts.
After two clamp nuts 5 are unclamped, pull screw rod 4 along main hoisting frame 1, laterally to slide by related slide block 3, drive pipe link 2 to slide along main hoisting frame 1 simultaneously, when the suspension centre being connected with lifting appliance Deng pipe link 2 moves to desired location, can, by clamp nut 5 lockings, avoid slide block 3 and pipe link 2 to move.
Continuation, with reference to figure 1, in order to adapt to more member, can arrange in a plurality of suspension hook 6(figure 2 suspension hooks are only shown on main hoisting frame 1), suspension hook 6 lays respectively at the desired location at the two ends of main hoisting frame 1.Suspension hook 6 is for being connected with member 7 to be hung, and the setting position of suspension hook 6 can arrange according to the size of member 7 to be hung, and for the member of different size, can use the suspension hook 6 of diverse location.
Fig. 2 is the diagram of circuit of using method of the suspender of another embodiment of the present invention.Below in conjunction with Fig. 1 and Fig. 2, describe the using method of suspender 100 in detail.
Specifically, the using method of described suspender comprises:
Step 1 a: member 7 to be hung is provided, indicates the center of gravity line A-A ' of member 7 on member 7;
Specifically, for member 7, can adopt the theoretical center of gravity line that calculates member 7 according to the shape of member 7 to be hung, and on member 7, indicate the center of gravity line A-A ' of member 7.
Step 2: member 7 is connected with suspender 100;
According to the size of member 7, select the suspension hook 6 of relevant position to be connected with member 7.
Step 3: unclamp clamp nut 5, moving slider 3 drives pipe link 2 to move, and the suspension centre of pipe link 2 is positioned on the center of gravity line A-A ' of member 7;
Clamp nut 5 is unclamped, pull screw rod 4 band movable sliders 3 and pipe link 2 to move, make the suspension centre of pipe link 2 follow movement, the suspension centre of so-called pipe link 2 refers to the point of connection that pipe link 2 and lifting are equipped, conventionally suspension centre is positioned on the line of centers of pipe link 2, and the suspension centre of pipe link 2 is positioned on the center of gravity line A-A ' of member 7.
Step 4: locking clamp nut 5, fixedly slide block 3;
The suspension centre of pipe link 2 be positioned at the line of centers A-A ' of member 7 upper after, by clamp nut 5 lockings, avoid slide block 3 and pipe link 2 to slide.
Step 5: utilize lifting equipment that member 7 is hung to bearing surface.
Utilize hanging device to leave member 7 under order bearing surface, because before lifting, the center of gravity line A-A ' that by slide block 3, the suspension centre of pipe link 2 has been moved to member 7 is upper, avoids because of Heave Here not on the center of gravity line of member 7, and produces.
But, because calculate by theory during the center of gravity line A-A ' of the member in above-mentioned steps 7, for fear of theory, calculate and the error that produces.Can member 7 be left under order after bearing surface in step 5, can reaffirm when member is sling whether have centre-of gravity shift, specifically, comprise the following steps:
Step 6: confirm whether there is centre-of gravity shift after member hangs 7;
Step 7: while there is centre-of gravity shift after member 7 is sling, member 7 is returned to described bearing surface, unclamps clamp nut 5, according to the situation of centre-of gravity shift, pull screw rod 4 band movable sliders 3 to move, make the suspension centre of pipe link 2 near the actual center gravity line of member 7;
Step 8: utilize lifting equipment that member 7 is hung to bearing surface again;
Step 9: repeat above-mentioned steps six to step 8, until member 7 while there is not centre-of gravity shift after slinging, utilizes lifting equipment that member 7 is sling to desired location.
In sum, suspender provided by the present invention comprises main hoisting frame, pipe link, a slide block, a screw rod and two clamp nuts, one end of described main hoisting frame pipe link is connected with described slide block, described slide block is positioned on described main hoisting frame, by slide block, slided and driven described pipe link laterally to slide along described main hoisting frame, the other end of described pipe link is connected with lifting equipment; Described screw rod runs through described slide block and is fixedly connected with described slide block, and two described clamp nuts lay respectively at the two ends of described screw rod.In above-mentioned suspender, by screw rod push-and-pull slide block, can will drive pipe link to move, the suspension centre of suspender can be moved, so that after lifting the suspension centre of suspender can the center of gravity line in member on, with guarantee member lifting and in place steadily, thereby realize the object that improves lifting efficiency and assurance construction safety.
Foregoing description is only the description to preferred embodiment of the present invention, the not any restriction to the scope of the invention, and any change, modification that the those of ordinary skill in field of the present invention is done according to above-mentioned disclosure, all belong to the protection domain of claims.
