Fig. 2 is the mode schematic diagram that the present invention lifts by crane steel reinforcement cage, and steel reinforcement cage is lifted by crane by level;
Fig. 3 is the process schematic that the steel reinforcement cage that the present invention lifts by crane is turned vertical state by level;
Fig. 4 is that the steel reinforcement cage that the present invention lifts by crane changes into vertical view completely.
Detailed description of the invention
Below in conjunction with accompanying drawing, assembly of the invention structures and methods are illustrated.
As shown in Figure 1, a kind of steel reinforcement cage lifting device provided by the invention, including loop wheel machine 1, suspension hook 2 at loop wheel machine 1 is connected below a horizontally disposed shoulder pole girder 3, the two ends, top of described shoulder pole girder 3 are respectively provided with hanger 4, and hanger 4 is connected with crane hook 2 by lanyard 5, and the two ends, bottom of described shoulder pole girder 3 set two fixed pulleys 6, one lifting rope 7 through described two fixed pulleys 6, lifting rope 7 be respectively arranged at two ends with hook 8; Being additionally provided with hoist engine 9 on loop wheel machine 1, the pull rope 10 of hoist engine 9 walks around loop wheel machine arm 11 front end and sagging, and the low end of pull rope 10 is divided into two strands, and each strand steel wire rope connects a hook respectively.
For adapting to the reinforcing bar cage hoisting of different-diameter, the present invention can set multiple same fixed pulley again between two fixed pulleys 6 set by the two ends, bottom of described shoulder pole girder 3. During use, according to steel reinforcement cage diameter, lifting rope walked around by the pulley selecting two distances suitable with steel reinforcement cage diameter.
The present invention adopts said apparatus, and the concrete grammar of lifting steel reinforcement cage is as follows:
As shown in Figure 2, suspension hook at loop wheel machine connects a horizontally disposed shoulder pole girder 32 times, the two ends, bottom of described shoulder pole girder 3 are provided with two fixed pulleys 6, one lifting rope 7 is walked around two fixed pulleys 6, the two ends of lifting rope 7 are along steel reinforcement cage 12 diametric(al) to be lifted, respectively through 2 points on the lifting end of hook mounting steel reinforcement cage 12;
Setting a hoist engine on loop wheel machine, the pull rope 10 of hoist engine walks around that loop wheel machine arm 11 front end is sagging, and the low end of pull rope is divided into two strands, and often one is equipped with hook, and a hook hangs over the steel reinforcement cage 1/3 place at lifting end to length of reinforcing cage; Another hangs over 2/3 place at lifting end to length of reinforcing cage, that is plays 1/3 place of length of reinforcing cage from the other end of steel reinforcement cage;
When steel reinforcement cage 12 lifts by crane, loop wheel machine arm 11 is lifted up, and keeps shoulder pole girder lifting rope 7 stress same with hoist engine pull rope 10, make steel reinforcement cage 12 be lifted and keep level in lifting process;
As shown in Figure 3, Figure 4, after steel reinforcement cage 12 rises certain altitude, hoist engine loosens pull rope 10 gradually, makes the other end height of steel reinforcement cage 12 be gradually reduced; Now lifting rope 7 can slide around fixed pulley 6, make reinforcement cage hoisting end two suspension centre uniform force, steel reinforcement cage unbalance stress is avoided to cause deformation, loop wheel machine makes reinforcement cage hoisting end keep suitably height simultaneously, to keep the steel reinforcement cage other end not to be advisable with earth surface all the time when declining, steel reinforcement cage end is avoided to be caused deformation by ground extruding, until steel reinforcement cage is completely in vertical state, now to slide into two ends length equal for lifting rope 7, reinforcement cage hoisting end two suspension centre stress is consistent, and the steel reinforcement cage of vertical state is hung by loop wheel machine to be installed toward stake holes.
