[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a machine vision-based intelligent hoisting tool for prefabricated buildings includes: a base pole 20, which is a tube with a concave cross-section; a vision module 21 is fixedly connected to the top center of the base pole 20; the vision module 21 consists of a sensor and a controller; a circular groove is opened through the bottom of the base pole 20; a probe 22 is fixedly connected in the groove; the top of the probe 22 is fixedly connected to the bottom of the vision module 21; the probe 22 and the vision module 21 are the same type of device used in the prior art (publication number: CN215828194U); the base pole 20 is hoisted by a crane during use, which is the prior art and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a self-balancing structure is installed on the wall of the base rod 20 for automatic balance adjustment. The self-balancing structure includes a rope drum 30, a transition shaft 31, and a timing frame 34. The rope drum 30 is symmetrically rotatably connected to the top of the base rod 20, the transition shaft 31 is symmetrically rotatably connected to the openings on both sides of the base rod 20, and the timing frame 34 is symmetrically arranged below the base rod 20. The wall of the rope drum 30 is wound with a suspension rope.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, both the rope drum 30 and the transition shaft 31 are drum-shaped. Both the rope drum 30 and the transition shaft 31 are fixedly connected at both ends to cylindrical parts inserted into the openings of the base rod 20. The rope on the wall of the rope drum 30 can contact the arc surface of the transition shaft 31. A motor for driving the rotation of the rope drum 30 is symmetrically installed on the wall of the base rod 20. The synchronous frame 34 is an inverted Y-shaped block, with an arc-shaped groove at the bottom. The symmetrical synchronous frames 34 have downward-facing synchronous openings. The self-balancing structure also includes a base frame 32 and a rotating block 33. The base frame 32 is symmetrically fixedly connected to the bottom of the base rod 20, and the rotating block 33 is rotatably connected to the bottom of each base frame 32. The base frame 32 has a downward-facing U-shaped opening. The base rod 20 has a curved bottom frame 32. The rotating block 33 is rotatably connected to the opening of the base frame 32. The top of each synchronous frame 34 can be fixedly connected to the bottom of the corresponding rotating block 33. The front and rear walls of each rotating block 33 are equipped with round blocks for insertion into the inner wall of the opening of the base frame 32. The two sides of the base rod 20 are also symmetrically provided with fine-tuning structures, which include: side frame 40, screw 41, moving block 42 and guide rope ring 43. The side frame 40 is symmetrically fixedly connected to the two openings of the base rod 20. The screw 41 is rotatably connected to the wall of each side frame 40. The moving block 42 is slidably connected to the wall of each side frame 40. The guide rope ring 43 is fixedly connected to the side wall of each moving block 42.

[0030] In practical use, the device is first hoisted above the building slab to be lifted using a crane. Then, the hoisting ropes on each side of the rope drum 30 are unwound by a motor. During unwinding, the ropes pass through the cavity of the rope guide ring 43. The symmetrical hoisting ropes on both sides are then fixed to the wall surface of the building slab to be lifted. The ropes are then wound up until the top of the building slab contacts the bottom opening of the symmetrical synchronous frame 34. The circular block on the wall of the rotating block 33 and the vision module 21 are connected by a circuit. The vision module 21 observes the rotation angle of the circular block on the wall of the bottom frame 32 in real time. When the building slab is moved, an imbalance occurs, at which point the synchronous frame 34... 4 will rotate synchronously with the building slab tilting around the circular block as the center. When the vision module 21 detects the rotation angle of the circular block, it will control the motor on the corresponding side wall to control the rope drum 30 to unwind or rewind the hoisting rope. Then, when preparing to lower the building slab, if the lowering position is not at the required position, the screw 41 can be controlled to rotate by the servo motor installed on the outer wall of the side frame 40 to drive the screw 41 to rotate. When the screw 41 rotates, the moving block 42 will move along the cavity of the side frame 40. As the moving block 42 drives the rope guide ring 43 to move in the required direction, the rope guide ring 43 will drive the hoisting rope in its cavity to move.

[0031] In summary, by setting up a self-balancing structure and using the vision module 21 to monitor the rotation angle of the circular blocks on the wall of the rotating block 33, the position of the hoisting rope is automatically unwound and rewound according to the tilt angle of the building slab, thereby achieving immediate and automatic correction of the unbalanced building slab, greatly reducing the safety hazards when unbalanced.

[0032] like Figure 5 As shown, the side frame 40 is a semi-enclosed frame. The top opening of the side frame 40 can be fixedly connected to the side wall of the base rod 20. The screw 41 rotates in the opening of the side frame 40. The wall of the screw 41 is threaded. The screw 41 can pass through the wall of the moving block 42 and be threadedly connected to the moving block 42. The side wall of the moving block 42 can slide against the cavity of the side frame 40. The rope ring 43 is located directly below the transition shaft 31 on each side. The rope ring 43 is circular. The suspension rope can pass through the cavity of the rope ring 43.

[0033] In practical use, the rotation of the screw 41 is controlled by a servo motor installed on the outer wall of the side frame 40 to drive the screw 41 to rotate. When the screw 41 rotates, the moving block 42 moves along the cavity of the side frame 40. As the moving block 42 drives the guide rope ring 43 to move in the desired direction, the guide rope ring 43 will drive the suspension rope in its cavity to move. At this time, the building slab will move in the desired direction synchronously.

[0034] In summary, by setting up a fine-tuning structure and utilizing the adjustable guide rope ring 43, the landing point of the building slab can be adjusted without controlling the crane, thus facilitating the placement of the building slab by the device.

[0035] Working principle: First, the device is hoisted above the building slab to be lifted by a crane. Then, the hoisting ropes on each side of the rope drum 30 are unwound by a motor. During unwinding, the ropes pass through the guide rope ring 43. The symmetrical hoisting ropes on both sides are then fixed to the wall of the building slab to be lifted. Next, the ropes are wound up until the top of the building slab contacts the bottom opening of the symmetrical synchronous frame 34. The circular block on the wall of the rotating block 33 and the vision module 21 are connected by wiring. The vision module 21 observes the rotation angle of the circular block on the wall of the bottom frame 32 in real time. When the building slab is moved, an imbalance occurs. At this time, the synchronous frame 34 rotates synchronously around the circular block as the building slab tilts. When the sensing module 21 detects the rotation angle of the circular block, it controls the motor on the corresponding side wall to control the rope drum 30 to unwind or rewind the hoisting rope. Then, when preparing to lower the building slab, if the lowering position has not reached the required position, the servo motor installed on the outer wall of the side frame 40 can be used to control the rotation of the screw 41. When the screw 41 rotates, the moving block 42 will move along the cavity of the side frame 40. As the moving block 42 drives the rope guide ring 43 to move in the required direction, the rope guide ring 43 will drive the hoisting rope in its cavity to move. At this time, the building slab will move in the required direction synchronously. After reaching the required position, the hoisting rope can be unwound and the building slab can be unloaded for assembly.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
