Description

Technical Field

[0001] The invention relates to the technical field of building hoisting equipment, in particular to an integrated equipment for hoisting and leveling assembled floor slabs. Background Art

[0002] In the construction of prefabricated buildings, the hoisting and leveling of prefabricated floor slabs are key links that affect the quality, progress and safety of construction. Traditional floor slab hoisting mainly relies on tower cranes or truck cranes with manual auxiliary adjustment, which has the following technical bottlenecks:

[0003] Low leveling accuracy: The floor slab is prone to tilt during the hoisting process due to center of gravity shift or wind influence. Manual leveling relies on experience and it is difficult to ensure installation accuracy, which may lead to difficulties in subsequent structural docking and even affect the overall quality of the building; cumbersome operation: Traditional hoisting equipment requires multiple people to work together, such as manually adjusting the length of the wire rope or using a crowbar to fine-tune the position of the floor slab, which is inefficient and poses a safety hazard.

[0004] Lack of adaptability: Floor slabs of different specifications (such as different thicknesses and reserved hole positions) require replacement of special hoists or adjustment of the hoisting plan, resulting in poor construction flexibility and increased equipment configuration costs; Stability issues: Floor slabs are prone to shaking during the hoisting process, and traditional clamps may cause the floor slabs to slip due to uneven force, especially in high-rise buildings where the risk is higher under the influence of wind loads.

[0005] At present, there are some automated lifting equipment on the market, but there are still problems such as slow leveling response speed, complex structure or high cost. For example, some equipment uses sensors to detect tilt and adjust it through motors, but lacks mechanical linkage design, resulting in leveling lag; other equipment can adapt to different floors, but the clamping mechanism is complex and the maintenance cost is high. Therefore, there is an urgent need for a lifting and leveling integrated equipment with a reasonable structure, precise leveling and strong adaptability to meet the needs of efficient and safe construction of modern prefabricated buildings.

A reinforcing column 41 is fixedly connected to the top of the mounting shell 6, and a lifting ring 7 is fixedly connected to the top of the reinforcing column 41.

[0029] The leveling assembly includes a biaxial winding motor 12 fixedly arranged at both ends of the mounting rod 5. The output shaft end of the biaxial winding motor 12 is fixedly connected to a winding wheel 9. A leveling rope 10 is wound around the winding wheel 9, and one end of the leveling rope 10 is fixedly connected to the hoisting plate 20.

[0030] The balance detection assembly includes a piston column 15 slidably and penetratingly arranged on a balance rod 16. A buffer member 17 is sleeved on the piston column 15 below the balance rod 16. A balance block 33 is fixedly connected to the bottom of the piston column 15, and a trapezoidal trigger block 35 is fixedly connected to the side wall of the piston column 15 above the balance rod 16.

[0031] A control power supply 14 is fixedly connected to the balance rod 16 on one side of the piston column 15. A push switch 34 is arranged on one side of the control power supply 14, and the push switch 34 is used to adjust the switch of the control power supply 14. The push switch 34 is correspondingly arranged with the trapezoidal trigger block 35. The electric energy output end of the control power supply 14 is connected to a conducting wire 13, and one end of the conducting wire 13 is connected to the biaxial winding motor 12 on the other side of the mounting rod 5.

[0032] The pressing assembly includes a buffer cylinder 27 fixedly arranged at the bottom of the mounting plate 18. A pressing column 28 is slidably arranged at the bottom end of the buffer cylinder 27. A telescopic member 29 is sleeved on the pressing column 28, and a pressing block 26 is fixedly connected to the bottom of the pressing column 28.

[0033] The clamping assembly includes movable grooves 36 opened on both sides of the hoisting plate 20. Movable blocks 21 are slidably arranged in the movable grooves 36. The movable blocks 21 are hinged to a transmission rod 19. A bearing rod 22 is fixedly connected to the bottom of the movable block 21, and a mounting ring 24 is fixedly connected to the bottom of the bearing rod 22.

[0034] An adjusting block 23 is slidably arranged in the mounting ring 24. An adjusting rod 31 is threadedly and penetratingly arranged on the adjusting block 23. The end of the adjusting rod 31 is rotatably connected to a clamping block 30. A clamping column 25 is fixedly connected to the clamping block 30 away from the adjusting rod 31. A rotating handle 32 is fixedly connected to the end of the adjusting rod 31 away from the clamping block 30.

[0035] During the implementation of the present invention, when hoisting operations are required, the clamping columns 25 on both sides of the bottom of the hoisting plate 20 are moved to both sides of the floor slab. Then, the operator moves the position of the adjusting block 23 according to the positions of the reserved holes on both sides of the floor slab, so that the clamping columns 25 correspond to the reserved holes. In this way, the device can be applied to floor slabs with reserved holes in different positions, making it more flexible to use. After the clamping columns 25 correspond to the reserved holes of the floor slab, the operator uses the hydraulic telescopic column 38 to drive the hoisting plate 20 to move downward. Under the action of the transmission rod 19, it can move through the movable block 21, and then drive the clamping columns 25 at the bottom of the bearing rod 22 to move to clamp and fix the floor slab. At the same time, under the action of the telescopic member 29, the pressing column 28 can drive the pressing block 26 to press and fix the floor slab, improving the hoisting stability. When hoisting the floor slab, if the precast floor slab material is uneven, it will rotate to one side, and at the same time drive the hoisting plate 20 and the mounting plate 18 to rotate. When the mounting plate 18 rotates, it will contact the balance block 33 and then drive the piston column 15 to move upward. The trapezoidal trigger block 35 at one end of the piston column 15 moves upward and contacts the pressing switch 34 to turn on the pressing switch 34, controlling the power supply 14 to drive the double-shaft winding motor 12 on the other side to start through the wire 13. The double-shaft winding motor 12 drives the hoisting plate 20 to rotate through the leveling rope 10 to achieve leveling. When the mounting plate 18 rotates, it will separate from the balance block 33. At this time, the trapezoidal trigger block 35 will separate from the pressing switch 34, and the double-shaft winding motor 12 stops winding. Generally speaking, this device can achieve automatic leveling, with higher hoisting stability and higher hoisting flexibility. It can hoist floor slabs with different reserved hole positions and has a larger scope of use.
