[0027] As shown in Figure 1 , Figure 2 , a hoisting system for a reinforcement cage of a engineering pile, comprising a hanging frame 1, a pair of fixed pulleys 2, a pair of slings 3, a pair of suspenders 4 and a lifting rope 5.

[0028] As shown in Figure 1 , the hanging frame 1 is horizontally arranged and used for connecting a main hook of a crane, the pair of fixed pulleys 2 are arranged at two ends of the hanging frame 1, and the pair of slings 3 are wound around each fixed pulley 2 respectively. The pair of suspenders 4 are horizontally arranged between the ends of the pair of slings 3, cross the reinforcement cage and support the annular main reinforcement of the reinforcement cage.

[0029] As shown in Figure 1 , Figure 3 , the suspender 4 is provided with a pair of positioning rods 41, the positioning rod 41 is provided with a semicircular bottom buckle 42, the bottom buckle 42 is rotatably connected with a semicircular top buckle 43, the bottom buckle 42 and the top buckle 43 are buckled with each other and clamped with the annular main reinforcement of the reinforcement cage. The top buckle 43 is provided with a hook 44, and the bottom buckle 42 is provided with a clamping hole 45 for the hook 44 to pass through.

[0030] As shown in Figure 1 , Figure 2 , the lifting rope 5 is used for connecting a secondary hook of the crane, and the two ends of the lifting rope 5 are respectively provided with a locking hook 51 for hooking the reinforcement cage.

[0031] When the reinforcement cage needs to be hoisted, the pair of suspenders 4 cross the first end and the middle position of the reinforcement cage, and the annular main reinforcement on the reinforcement cage is embedded in the bottom buckle 42 on the positioning rod 41, then the top buckle 43 is controlled to flip and the hook 44 is embedded in the clamping hole 45, the locking of the bottom buckle 42 and the top buckle 43 is realized, and the fixing of the suspender 4 and the reinforcement cage is completed.

[0032] Then the sling 3 is connected to the two ends of the suspender 4, and the locking hook 51 on the lifting rope 5 is hooked on the two sides of the tail end position of the reinforcement cage. Then the main hook and the secondary hook of the crane are synchronously matched to hoist the reinforcement cage, and the main hook and the secondary hook are matched to slowly stand up the reinforcement cage, and finally the reinforcement cage is placed in the pile hole to complete the hoisting and placing of the reinforcement cage.

[0033] Therefore, by setting the positioning rods 41 on the hoisting rods 4, and adopting the mutual buckling of the bottom buckles 42 and the top buckles 43, the hoop fixing of the ring-shaped main reinforcement of the reinforcement cage is realized, so that the positioning of the hoisting rods 4 is realized, the transverse slipping between the hoisting rods 4 and the reinforcement cage is avoided, and the stability of the reinforcement cage during hoisting is increased.

[0034] As shown in Figure 3 , the positioning rods 41 are horizontally and slidingly connected to the hoisting rods 4, and the hoisting rods 4 are provided with a driving mechanism 6 for controlling the relative sliding of the positioning rods 41.

[0036] When the reinforcement cages with different diameters need to be hoisted, the hand wheel 62 can be controlled to drive the bidirectional screw rod 61 to rotate, the relative sliding of the pair of positioning rods 41 is controlled by the bidirectional screw rod 61, the adjustment of the spacing between the positioning rods 41 is realized, and the reinforcement cages with different diameters are adapted. At the same time, the pair of positioning rods 41 are always in a symmetrical state, the balanced hoisting of the reinforcement cage is ensured, and the stable hoisting of the reinforcement cage is completed.

[0039] Before hoisting the reinforcement cage, the positioning reinforcement 71 is horizontally placed on the adjacent vertical reinforcement, and the clamping jaws 73 clamp the vertical reinforcement, so that the preliminary fixing of the positioning reinforcement is realized, and finally the positioning reinforcement 71 is fixed to the vertical reinforcement by using the steel wire, and the fixing of the positioning device 7 is completed.

[0040] When the reinforcement cage is lowered into the pile hole, the roller 72 can make the reinforcement cage smoothly and stably slide into the pile hole, so that the stable hoisting construction of the reinforcement cage is realized. And since the roller 72 is a cement block, it can be integrated after pouring, thereby increasing the structural strength and stability of the engineering pile.
