The lower end of the sleeves 3 is fixedly connected to the base plate 4. The lower surface of foot 2 is connected to the base plate 4 via spring shock absorber 5. Square sleeves 6 are fixed on the outer walls of the front and rear sides of the base 1, and lifting rings 7 are fixedly installed on the outer walls of the square sleeves 6. Limiting arms 8 are fixedly provided on the outer walls of the ends of the square sleeves 6, and limiting buttons 9 are movably connected to the inner walls of the limiting arms 8. Toothed plates 10 are movably provided at the ends of the limiting buttons 9.

A positioning mechanism 15 is provided on the outer walls of the baffles 14.

[0026] The support foot 2 and the sleeve 3 form a sliding structure, which allows the support foot 2 to move relative to the sleeve 3 when the device is lowered, and drive the spring shock absorber 5 to deform, thereby buffering the lowered floor slab.

[0027] Both the square sleeve 6 and the base 1 are slidably connected to the right rack 12, and both the square sleeve 6 and the base 1 form a sliding structure with the left rack 13, which makes it easy for the user to move the right rack 12 and the left rack 13 respectively, so that the baffle 14 can fit against the end face of the floor slab.

[0028] The limiting arm 8 and the limiting button 9 are threaded together, and the limiting button 9 and the toothed plate 10 are rotatably set, so that the user can rotate the limiting button 9 to move relative to the limiting arm 8, thereby driving the toothed plate 10 to move.

[0029] A locking rod 11 is fixedly connected to the outer wall of the toothed plate 10 on the side of the limit button 9, and the locking rod 11 and the limit arm 8 are slidably connected, so that when the toothed plate 10 moves, the toothed plate 10 drives the locking rod 11 to slide relative to the limit arm 8, thereby making the toothed plate 10 move stably.

[0030] The rack plate 10 is engaged with the right rack 12 and the left rack 13 respectively, so that the right rack 12 or the left rack 13 is limited by the rack plate 10, thereby ensuring the stability of the baffle 14.

[0031] The positioning mechanism 15 comprises a positioning frame 1501, a knob 1502 and a clamping plate 1503, the positioning frame 1501 is fixedly connected to the outer wall of the baffle 14, the upper end inner wall of the positioning frame 1501 movably installs the knob 1502, and the lower end of the knob 1502 rotatably installs the clamping plate 1503, so as to limit the vertical direction of the floor through the positioning mechanism 15.

[0032] The knob 1502 and the positioning frame 1501 are screw-threaded, so that the user rotates the knob 1502, so that the knob 1502 moves downward relative to the positioning frame 1501, thereby driving the clamping plate 1503 to abut against the floor to limit the floor.

[0033] Working principle: when using the hoisting device for the prefabricated composite floor, first, as shown in Figs. 1-6 the user moves the right rack 12, at this time the right rack 12 slides relative to the base 1 and the square sleeve 6, then the right rack 12 drives the baffle 14 on it to abut against the end face of the floor, then the user rotates the limiting knob 9 on the side of the right rack 12, then the limiting knob 9 moves relative to the limiting arm 8, then the limiting knob 9 drives the rack plate 10 to move, and as the rack plate 10 moves, the rack plate 10 drives the clamping rod 11 to slide relative to the limiting arm 8, then the rack plate 10 moves and engages with the right rack 12, thereby limiting the right rack 12 to ensure the stability of the baffle 14 limiting the floor, and the left rack 13 is operated in the same way, thereby limiting the floor in the transverse direction, then the user rotates the knob 1502, then the knob 1502 moves downward relative to the positioning frame 1501, then the knob 1502 drives the clamping plate 1503 to move downward, then the clamping plate 1503 moves and abuts against the floor, and the remaining positioning mechanisms 15 are operated in the same way, thereby limiting the floor in the longitudinal direction, so that the stability of the device and the composite floor is improved, thereby ensuring the safety of the hoisting of the prefabricated composite floor, then the user connects the lifting ring 7 with the hoisting mechanism through the steel cable, then the user hoists the base 1 through the hoisting mechanism to hoist the floor, and when the device hoists the floor to the required position and lowers the floor, first, the bottom plate 4 contacts the ground, then the base 1 drives the supporting leg 2 to slide downward relative to the sleeve 3, at this time the supporting leg 2 drives the spring shock absorber 5 to deform, thereby buffering the floor, so that the device buffers the floor when lowering the floor, thereby protecting the floor and improving the practicality of the device.
