Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to an anti-tilting and balancing auxiliary device for floor slab hoisting. Background Technology

[0002] In building construction, the hoisting of floor slabs is a common and crucial process, typically requiring the use of cranes, wire ropes, and hooks to lift precast floor slabs from the ground to a designated location for installation. However, in actual hoisting operations, due to the large size and uneven center of gravity of the floor slabs, and the difficulty in achieving perfect symmetry in the lifting points, the floor slabs are prone to tilting or swaying during crane lifting. This tilting not only leads to instability in the air, increasing the difficulty of operation for construction workers, but also may cause the floor slab to collide with other structural components, posing significant safety hazards.

[0003] To address the issue of floor slab tilting during hoisting, some existing technologies employ methods such as installing balance bars on the hoisting ropes or adjusting the position of the hoisting points to improve the stress state of the floor slab. However, these solutions are mostly passive balancing structures, unable to adjust the rope length in real time according to the actual hoisting conditions, and still struggle to maintain dynamic balance when the floor slab is subjected to wind force, off-center loading, or changes in the crane's lifting angle. Furthermore, some balancing devices have complex structures, and the adjustment process relies on manual operation, resulting in drawbacks such as slow response, low adjustment accuracy, and inconvenient control. Consequently, the stability and safety of floor slab hoisting still need improvement. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a floor slab hoisting anti-tilting balance auxiliary device, which can automatically adjust and maintain balance in real time during the floor slab hoisting process, so as to solve the problem of floor slab tilting and improve the safety and reliability of hoisting operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A floor slab hoisting anti-tilting balance auxiliary device includes a horizontal balance plate, a first main hoisting rope and a second main hoisting rope, the lower end of the first main hoisting rope being fixedly connected to the left end of the balance plate; A balance adjustment component is fixed on the upper surface of the balance plate near the right end. The lower end of the second main hoisting rope is fixedly connected to the balance adjustment component, which controls the winding and unwinding of the second main hoisting rope. Several secondary suspension ropes, evenly arranged front to back, are fixed on the lower surface of the balance plate near both the left and right ends. The lower ends of the secondary suspension ropes are fixed with hooks that hang in the holes in the floor slab.

[0006] Furthermore, the balance adjustment assembly includes a fixed base fixed to the balance plate, a rope winding mechanism for winding and coiling the second main hoisting rope fixed on the fixed base, and a drive mechanism for driving the rope winding mechanism to perform the winding operation fixed on the fixed base.

[0007] Furthermore, the rope winding mechanism includes two support plates fixed on the fixed base, and a winding roller is rotatably installed between the two support plates. One end of the central shaft of the winding roller passes through the support plate and is fixed with a worm gear, and an annular rope winding groove is opened on the outer side of the winding roller.

[0008] Furthermore, the drive mechanism includes a first fixed plate and a second fixed plate fixed on the left and right sides of the fixed base. A worm gear meshing with a worm wheel is rotatably installed between the first fixed plate and the second fixed plate. A motor that drives the worm gear to rotate is fixed on the right side of the second fixed plate.

[0009] Furthermore, several mounting plates are fixed on both the left and right sides of the fixing base, and fixing holes are also provided on the upper surface of the fixing base.

[0010] Furthermore, the hook includes a vertical rod and a horizontal rod, the lower end of the vertical rod is fixedly connected to one end of the horizontal rod, and the angle between the vertical rod and the horizontal rod is an acute angle.

[0011] Furthermore, a lifting ring that is fixed to the first main lifting rope is fixed on the upper surface of the balance plate near the left end, and several fixing rings arranged in a front-to-back pattern are fixed on the lower side of the balance plate near the left and right ends.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This anti-tilting balancing auxiliary device for floor slab hoisting, by setting a first main hoisting rope, a second main hoisting rope, and multiple auxiliary hoisting ropes on a balancing plate, forms a multi-point support system for the hoisting structure under stress, effectively solving the tilting problem caused by uneven stress in existing floor slab hoisting. Through the lateral arrangement of the balancing plate, the load at the hoisting points can be distributed during the hoisting process, ensuring uniform stress on the floor slab during lifting, raising, and positioning phases. This significantly improves the stability and safety of the hoisting, and reduces the impact of floor slab tilt on construction accuracy and efficiency.

[0013] This device controls the winding and unwinding of the second main hoisting rope through a balance adjustment component mounted on a balance plate, achieving automatic adjustment of the balance during floor slab hoisting. Compared to the traditional method of manually adjusting the rope length, this solution can adjust the rope tension in a timely manner according to the stress on the floor slab, maintaining consistent stress on both ends and preventing the floor slab from tilting due to differences in the height of the hoisting points. This improves the control accuracy and safety factor during the hoisting process.

[0014] The balance adjustment component of this device consists of a rope winding mechanism and a drive mechanism. A motor drives a worm gear and worm wheel to achieve precise rotation of the winding roller, thereby enabling fine-tuning of the length of the second main lifting rope. This structure can correct the floor slab tilt angle in real time during hoisting, solving the problems of slow adjustment and delayed response in traditional hoisting devices, making the hoisting process more efficient and stable.

[0015] The auxiliary lifting ropes and hooks in this device are designed with even distribution at the front and back. The hooks are connected at an acute angle to the vertical and horizontal bars to form a self-locking structure, which automatically tightens against the upper edge of the floor slab opening when under force, preventing the hooks from loosening. This structure ensures reliable fixation of the floor slab during the lifting process, effectively solving the problems of hook slippage and insecure clamping in traditional hoisting, and further improving hoisting safety.

[0016] The device features a balance plate with multiple fixed rings for multi-point connection with the auxiliary lifting ropes. A lifting ring at the left end of the balance plate connects to the first main lifting rope, while a balance adjustment assembly at the right end allows for independent control of the left and right ends. This structural design improves the overall stability of the hoisting system, preventing swaying caused by center of gravity shift during hoisting, thus ensuring the safety and reliability of the floor slab hoisting operation and the stability of construction quality.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a floor slab hoisting anti-tilting balancing auxiliary device includes a horizontal balancing plate 1, a first main hoisting rope 2, and a second main hoisting rope 3. The lower end of the first main hoisting rope 2 is fixedly connected to the left end of the balancing plate 1. This structure is used to provide support and traction to both ends of the floor slab simultaneously during hoisting operations. However, in traditional hoisting operations, the fixed length of the hoisting ropes often leads to uneven stress on the floor slab, causing it to tilt and affecting the hoisting stability. To solve this problem, the balancing plate 1 adopts a high-strength alloy steel plate structure to ensure overall bending stiffness, and the separate installation of the first main hoisting rope 2 and the second main hoisting rope 3 makes the hoisting point position adjustable. The system includes a balance plate 1 with a balance adjustment component 4 fixed on the upper surface near the right end. The lower end of the second main lifting rope 3 is fixedly connected to the balance adjustment component 4. The balance adjustment component 4 controls the winding and unwinding of the second main lifting rope 3, thereby achieving dynamic adjustment of the lifting balance. Several secondary lifting ropes 5 are fixed on the lower surface of the balance plate 1 near both the left and right ends. The lower end of the secondary lifting ropes 5 is fixed with a hook 6 that hangs in the hole in the floor slab. The secondary lifting ropes 5 distributed at multiple points can disperse the force during the lifting process, prevent stress concentration at local lifting points, and thus improve the balance and safety of the floor slab lifting.

[0021] like Figure 2 As shown, the balance adjustment component 4 includes a fixed base 43 fixed on the balance plate 1. A rope winding mechanism 41 for winding and coiling the second main hoisting rope 3 is fixed on the fixed base 43, and a drive mechanism 42 for driving the rope winding mechanism 41 to perform the winding operation is also fixed on the fixed base 43. In traditional hoisting structures, the length of the hoisting rope is adjusted manually, resulting in low adjustment accuracy and slow response, making it impossible to correct the tilt angle of the floor slab in real time. To overcome this defect, the fixed base 43 adopts a high-strength steel structure and automatically winds and unwinds the rope through a mechanical transmission mechanism, so that the balance adjustment component 4 can automatically correct itself according to the posture of the floor slab during the hoisting process, ensuring the overall balance and stability of the hoisting.

[0022] like Figure 3As shown, the rope winding mechanism 41 includes two support plates 414 fixed on the fixed base 43, one at the front and one at the back. A winding roller 411 is rotatably mounted between the two support plates 414. One end of the central shaft of the winding roller 411 passes through the support plate 414 and is fixed with a worm gear 413. An annular rope winding groove 412 is provided on the outer side of the winding roller 411. During the hoisting process, the winding roller 411 achieves precise angular displacement control through the worm gear transmission system, so that the second main hoisting rope 3 can be linearly extended and retracted. The annular design of the rope winding groove 412 can effectively prevent the hoisting rope from knotting, slipping or overlapping during the winding process, thereby ensuring the smoothness and safety of the winding movement. This structure allows small tilt changes during floor hoisting to be quickly corrected, thereby improving hoisting efficiency.

[0023] like Figure 4 As shown, the drive mechanism 42 includes a first fixed plate 421 and a second fixed plate 423 fixed on the left and right sides of the fixed base 43. A worm 422 meshing with a worm wheel 413 is rotatably mounted between the first fixed plate 421 and the second fixed plate 423. A motor 424 that drives the worm 422 to rotate is fixed on the right side of the second fixed plate 423. In actual construction, the traditional manual rope winding method has problems of adjustment lag and low control precision. However, the drive mechanism 42 can realize the mechanical transmission of the power output by the motor 424, which drives the worm 422 to drive the worm wheel 413 to rotate in a decelerated and high-torque manner. A stable meshing relationship is formed between the worm 422 and the worm wheel 413, which can convert the high-speed rotation of the motor 424 into the low-speed and high-precision rotation of the winding roller 411, so that the second main lifting rope 3 can be gradually wound and unwound. This enables dynamic fine-tuning of the height of the right end during the floor slab hoisting process and prevents the floor slab from tilting to the left or right.

[0024] like Figure 5 As shown, several mounting plates 431 are fixed on both the left and right sides of the fixed base 43, and fixing holes 432 are also provided on the upper surface of the fixed base 43. The mounting plates 431 are used to bolt and fix the balance plate 1 to ensure the vibration resistance stability of the balance adjustment assembly 4 during long-term hoisting. The fixing holes 432 are used to insert fasteners or sensing elements to facilitate monitoring the operating status of the rope winding mechanism 41. This design makes the entire adjustment assembly form a rigid support frame in structure, which improves the overall reliability of the equipment.

[0025] like Figure 6As shown, the hook 6 includes a vertical rod 61 and a horizontal rod 62. The lower end of the vertical rod 61 is fixedly connected to one end of the horizontal rod 62, and the included angle between the vertical rod 61 and the horizontal rod 62 is an acute angle. When hoisting a floor slab, the horizontal rod 62 is inserted into the hole in the floor slab. During hoisting, the auxiliary hoisting rope 5 pulls the vertical rod 61 upward, causing one end of the horizontal rod 62 to tilt upward and press against the top of the hole, thus completing the hooking during the hoisting of the floor slab. Compared with the traditional ring hook, this structure can achieve a self-locking clamping effect. During the hoisting process, it can automatically adjust the angle according to the force, preventing the hook from disengaging or loosening, and improving the safety and reliability of the hoisting operation.

[0026] like Figure 7 As shown, a lifting ring 11, which is fixedly connected to the first main lifting rope 2, is fixed on the upper surface of the balance plate 1 near the left end, and several fixed rings 12 arranged in a front-to-back pattern are fixed on the lower side of the balance plate 1 near the left and right ends. The lifting ring 11 is used to connect the main lifting device of the crane to ensure that the vertical force transmission of the balance plate 1 is uniform when under force. The fixed rings 12 are used to install the auxiliary lifting rope 5 and form a multi-point force distribution, so that the force distribution is more balanced when the floor slab is hoisted. This structure effectively avoids the twisting and rotation phenomena caused by the center of gravity shift in traditional single-point hoisting, thereby ensuring the balance and stability of the floor slab throughout the entire hoisting and installation process.

[0027] The working principle of this utility model is as follows: When hoisting a floor slab, the upper ends of the first main hoisting rope 2 and the second main hoisting rope 3 are fitted onto the hoisting device of the crane. Then, the hooks 6 on several auxiliary hoisting ropes 5 are hung in the holes at both ends of the floor slab. At this time, the crane lifts the first main hoisting rope 2 and the second main hoisting rope 3 upward, so that the balance plate 1 drives the auxiliary hoisting ropes 5 and the hooks 6 to lift the floor slab. When the floor slab tilts to the left or right, the motor 424 drives the worm gear 422 to rotate. The rotating worm gear 422 drives the worm wheel 413 to drive the winding roller 411 to rotate and wind or unwind the second main hoisting rope 3, thereby adjusting the right end of the balance plate 1 to raise and lower, thus completing the adjustment during the hoisting of the floor slab and ensuring the balance of the floor slab hoisting.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
