[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a hoisting tool for vertical precast concrete slabs in prefabricated buildings, including a beam frame 2. A lifting ring 1 is provided at the top of the beam frame 2. Openings are provided at both ends of the beam frame 2, and a sliding groove is provided at the bottom of the beam frame 2. A connecting frame 8 is inserted into the sliding groove. This connecting frame 8 can slide laterally, thereby adjusting the positions of the two sets of clamping sleeves 4 and clamping telescopic rods 7, thus facilitating adjustment by workers when imbalance occurs during hoisting. The top of the connecting frame 8 has a "T"-shaped structure, and second fixing bolts 9 are inserted into the openings at both ends of the beam frame 2. One end of the second fixing bolt 9 passes through the beam frame 2 and is fixedly connected to the connecting frame 8; this structure can fix the position of the connecting frame 8 through the second fixing bolt 9; the connecting frame 8 is slidably connected to the bottom of the beam frame 2, and the clamping sleeve 4 at one end of the connecting frame 8 is fixedly connected to the connecting frame 8, while the clamping sleeve 4 at the other end of the connecting frame 8 is rotatably connected to the connecting frame 8; this structure can achieve clamping of the precast concrete slab 5 to be hoisted through two sets of clamping sleeves 4 and clamping telescopic rods 7, ensuring the stability of the precast concrete slab 5 during hoisting; a level is set on one side of the beam frame 2. Bubble 3, connecting frame 8 is symmetrically distributed about the bisector of beam frame 2. One end of connecting frame 8 is rotatably connected to clamping sleeve 4. The bottom of clamping sleeve 4 has a groove, and clamping telescopic rod 7 is inserted into the groove. The outer wall of clamping telescopic rod 7 has a through hole. The outer wall of clamping sleeve 4 is connected to a first fixing bolt 6. One end of the first fixing bolt 6 passes through clamping sleeve 4 and is inserted into clamping telescopic rod 7. Clamping sleeve 4, first fixing bolt 6 and clamping telescopic rod 7 are all symmetrically distributed about the bisector of connecting frame 8. This structure is achieved by the first fixing bolt 6. The device ensures the stability of the connection between the clamping sleeve 4 and the clamping telescopic rod 7. The length of the clamping telescopic rod 7 can be adjusted by sliding to accommodate the hoisting of precast concrete slabs 5 at different heights. The lower end of the clamping sleeve 4 is telescopically connected to the clamping telescopic rod 7, which clamps the precast concrete slab 5 to be hoisted on its inner side. The device uses a spirit level 3 to easily check the balance during hoisting, thereby improving the safety of hoisting. After clamping the precast concrete slab 5 to be hoisted, the lower end of the clamping telescopic rod 7 is sealed with a first fixing bolt 6.

[0022] Working principle: When using this prefabricated building vertical precast concrete slab hoisting tool, first connect the lifting ring 1 to the crane hook, then rotate and open the clamping sleeves 4 at both ends of the beam frame 2. Then place the precast concrete slab 5 to be hoisted on the inner wall of the clamping sleeve 4 and the clamping telescopic rod 7 at the front end of the beam frame 2. Next, rotate the clamping sleeve 4 at the rear end so that the clamping sleeve 4 and the clamping telescopic rod 7 clamp the precast concrete slab 5 to be hoisted. Then use the first fixing bolt 6 to connect and fix the bottom of the two clamping telescopic rods 7. Then the precast concrete slab 5 to be hoisted is lifted off the ground. At this time, check the levelness of the hoisting through the bubble level 3. If it is not balanced, remove the second fixing bolt 9 and move the position of the precast concrete slab 5 to be hoisted through the sliding connecting frame 8 until the two sides of the precast concrete slab 5 are balanced. Then use the second fixing bolt 9 to fix the connecting frame 8.
