Description

TECHNICAL FIELD

[0001] The present application relates to a hoisting device, in particular to a self-adaptive wind load anti-shaking heavy component hoisting device, belonging to the technical field of hoisting machinery. BACKGROUND

[0002] The heavy component hoisting device is the core equipment in the fields of modern construction engineering, wind power construction, bridge construction, etc., and is mainly used for vertical lifting and horizontal transfer of large-weight and large-volume components such as steel components, wind power blades, and bridge main beams. The hoisting stability thereof is directly related to the construction efficiency, component safety, and personnel protection. In outdoor hoisting operations, wind load is a key environmental factor affecting the stability of the components. Wind of different intensities can easily cause the hoisted components to produce horizontal shaking, swinging, and other deviation phenomena. Especially for heavy components, slight shaking can cause precise positioning difficulties, component collision damage, and other problems. Therefore, the industry has developed various hoisting anti-shaking devices. For example, the Chinese Utility Model Patent with the publication number CN222007086U discloses an anti-shaking device for a hoisting device, and specifically discloses that the anti-shaking device includes two mounting plates, a clamping assembly arranged between the two mounting plates, and an anti-shaking mechanism arranged between the two mounting plates. The clamping assembly includes a first clamping plate, a second clamping plate, two clamping blocks arranged on one side of the second clamping plate, two clamping grooves arranged on one side of the first clamping plate, and a plurality of mounting holes arranged on the coinciding sides of the first clamping plate and the second clamping plate. However, in such devices, the hoisted part is mainly limited by rigid structures. When hoisting large-weight heavy components, the components themselves have a large gravity, and are easily disturbed by wind load to produce instantaneous shaking or load fluctuation in outdoor operations. The rigid structure needs to continuously bear the combined forces of gravity and wind load, and the stress concentration parts are easily accumulated with fatigue damage in a high load state for a long time. In long-term use or extreme working conditions, the rigid structure may face the risk of bending and breaking. SUMMARY

[0003] The present application aims to provide a self-adaptive wind load anti-shaking heavy component hoisting device. Through active and passive methods, the present application can self-adaptively offset the shaking of the hoisted components, and improve the hoisting safety and stability.

[0008] The aforementioned adaptive wind load anti-sway heavy component hoisting equipment includes a cable lifting mechanism comprising multiple second cable reels mounted on a mounting frame, multiple first fixed pulleys symmetrically arranged on both sides of the mounting frame, and multiple second fixed pulleys symmetrically arranged on both sides of the upper end of the clamping mechanism; the second cable reels are provided with lifting cables, which are connected to the mounting frame after passing through the first and second fixed pulleys on the same side; the mounting frame is provided with multiple fourth reducers, and the input end of the fourth reducers is provided with a fifth motor; the output end of the fourth reducers is fixedly connected to the rotating shaft of the second cable reels.

[0009] The aforementioned adaptive wind load anti-sway heavy component hoisting equipment has a support beam at the upper end of the upright frame, and multiple ropes are provided between the support beam and the cross frame.

[0010] The aforementioned adaptive wind load anti-sway heavy component hoisting equipment includes a clamping mechanism that is connected to the lifting end of the cable lifting mechanism, and a clamping arm is slidably connected to the side of the clamping frame; a hydraulic cylinder is provided inside the clamping frame, and the telescopic end of the hydraulic cylinder is connected to the clamping arm.

[0012] In the aforementioned adaptive wind load anti-sway heavy component hoisting equipment, a connecting block is provided between the moving block and the mounting frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the overall position of the support frame can be adjusted by the first moving mechanism to quickly locate the initial hoisting area; then, the horizontal position of the clamping mechanism is adjusted by the second moving mechanism to ensure precise alignment with the heavy component, improving the positioning efficiency in the early stage of hoisting; during the movement of the mounting frame by the second moving mechanism, the follow-up mechanism makes the first cable reel move synchronously with the mounting frame; the cable lifting mechanism can smoothly lower the clamping mechanism above the component, and the clamping mechanism clamps the component. When the component sways due to wind load and its own movement during hoisting and transportation, the movement of the second moving mechanism can quickly offset the sway along the horizontal frame direction, maintaining stability in that direction; for the sway in the vertical horizontal frame direction, when the sway is small, the passive adjustment mechanism can directly buffer and offset it, reducing the impact on the equipment; when the sway is large, the first cable reel on the corresponding side is driven by the second motor to retract or release the adjustment cable, pulling the component back to the preset position, effectively offsetting the sway, and comprehensively improving the stability and safety of the hoisting process of heavy components.

[0014] 2. In this invention, when the clamping frame shakes, the passive adjustment mechanism can cause the spring to adapt to the shaking of the component by rotating the first rod relative to the mounting plate, rotating the second rod relative to the clamping frame, and sliding the guide rod along the first rod. The spring can quickly generate a reverse restoring force with its own elasticity, and can passively reduce the shaking without additional power. This can not only buffer the impact of shaking on the clamping frame and the heavy component being lifted, preventing the component from shifting or colliding due to shaking, but also reduce the load of shaking on other parts of the equipment, maintain the relative stability of the component during the lifting process, and further ensure the safety and stability of the lifting of heavy components.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: An adaptive wind load anti-sway heavy component hoisting equipment, configured as follows Figures 1-8 As shown, the system includes a vertical frame 1, which is welded from Q355B steel plate and is used to support the horizontal frame 3 and various hoisting components, providing stable vertical support for the entire equipment and ensuring that the structure does not deform during hoisting. A first moving mechanism 2 is located below the vertical frame 1 to drive the overall movement of the vertical frame 1, enabling flexible transfer of the equipment within the work site and rapid positioning of the initial hoisting area. A horizontal frame 3 is located above the vertical frame 1, made of the same material as the vertical frame 1, and is used to install a second moving mechanism 4 and a first guide rail 10, providing a support carrier for the horizontal movement of the hoisting components. A support beam 23 is located at the upper end of the vertical frame 1, made of H-beam steel, to enhance the connection stability between the horizontal frame 3 and the vertical frame 1, distribute the hoisting load borne by the horizontal frame 3, and prevent the ends of the horizontal frame 3 from sagging. Multiple ropes 24, made of high-strength steel wire rope, are provided between the support beam 23 and the horizontal frame 3 to assist in pulling and fixing the horizontal frame 3, further improving the wind load resistance and structural rigidity of the horizontal frame 3, and preventing the horizontal frame 3 from swaying during hoisting. The crossbeam 3 is equipped with a second moving mechanism 4, which drives the mounting frame 5 to move horizontally and adjusts the horizontal position of the clamping mechanism 25 to ensure precise alignment with the heavy component. The moving end of the second moving mechanism 4 is equipped with a mounting frame 5, which is made of Q355B steel plates and is used to install the cable lifting mechanism 6 and the passive adjustment mechanism 21, providing an installation reference for the hoisting execution components. The mounting frame 5 is equipped with the cable lifting mechanism 6, which drives the clamping frame 7 to move vertically, smoothly lowering the clamping frame 7 above the component or raising it to a preset height. Figure 4 As shown, the lifting end of the cable lifting mechanism 6 is equipped with a clamping mechanism 25. The clamping mechanism includes a clamping frame 7 connected to the lifting end of the cable lifting mechanism 6. The clamping frame 7 is welded from Q355B steel plate and is used to install the clamping arm 8, hydraulic cylinder 9, and sensor 20 to support and fix heavy components. The clamping arm 8 is slidably connected to the side of the clamping frame 7. The clamping arm 8 is forged from 45# steel and is used to clamp heavy components. It fixes the components by friction with the surface of the components to prevent them from falling off during hoisting. The clamping frame 7 is equipped with a hydraulic cylinder 9. The hydraulic cylinder 9 is a high-pressure hydraulic cylinder used to provide clamping power and drive the clamping arm 8 to slide along the side of the clamping frame 7 to realize the contraction and clamping or expansion and release actions. Its telescopic end is connected to the clamping arm 8. The extension and contraction of the telescopic end is controlled by the pressure change of the hydraulic oil, thereby driving the clamping arm 8 to move. Figure 2As shown, a follower mechanism 26 is symmetrically arranged below the crossbeam 3. The follower mechanism 26 includes a first guide rail 10 arranged below the crossbeam 3. The first guide rail 10 is a linear guide rail, used to guide the moving block 11 and ensure that the moving block 11 slides smoothly along a fixed direction. The moving block 11 is slidably connected to the first guide rail 10. The moving block 11 is made of Q355B steel plate and is used to install the first motor 14, connecting rod 15 and first cable reel 16. It moves synchronously with the mounting frame 5 to provide installation support for adjusting the cable 17. The moving block 11 has a slot 12, and multiple first rollers 13 are rotatably connected in the slot 12. The first rollers 13 are bearing rollers, used to reduce the frictional resistance between the moving block 11 and the first guide rail 10, so that the moving block 11 can move smoothly along the first guide rail 10. The first rollers 13 abut against the first guide rail 10, and rolling friction replaces sliding friction to reduce movement resistance. Figure 3 As shown, the inner side of the moving block 11 is provided with multiple first motors 14. Each first motor 14 is a servo motor, used to provide driving power to drive the first roller 13 to rotate. Its output end is connected to the first roller 13, and the rotation of the motor output shaft drives the first roller 13 to rotate synchronously. A connecting block 22 is provided between the moving block 11 and the mounting frame 5. The connecting block 22 is made of Q355B steel plate and is used to connect the moving block 11 and the mounting frame 5, forming a linkage structure. This ensures that the moving block 11 can follow synchronously when the mounting frame 5 moves, avoiding relative displacement affecting the tension stability of the adjustment cable 17. Figure 4As shown, the outer side of the movable block 11 is provided with multiple connecting rods 15. The connecting rods 15 are made of seamless steel pipe of No. 45 steel and are used to support the first cable reel 16, providing a stable mounting point for the first cable reel 16. The end of the connecting rod 15 is rotatably connected to the first cable reel 16, which is welded from Q355B steel plate and is used to retract and extend the adjustment cable 17. The position of the clamping frame 7 is controlled by adjusting the retraction or extension of the cable 17. The first cable reel 16 is provided with an adjustment cable 17, which is made of high-strength nylon rope and is used to pull the clamping frame 7 to counteract large swaying in the direction perpendicular to the crossbeam 3. Its outer end is connected to the clamping frame 7, and the clamping frame 7 is reset by the change in cable tension. The outer side of the connecting rod 15 is provided with a second motor 18. The second motor 18 is a servo motor, used to provide driving power for the reel, driving the first cable reel 16 to rotate. The output end of the second motor 18 is equipped with a first reducer 19, which is a planetary gear reducer, used to reduce the motor speed and increase the output torque, ensuring that the first cable reel 16 receives sufficient torque to wind and unwind the cable 17. Its output end is connected to the first cable reel 16, and the rotation of the reducer's output shaft drives the first cable reel 16 to rotate synchronously. The clamping frame 7 is equipped with a sensor 20, which can be an angle sensor, used to monitor the deflection angle and swaying state of the clamping frame 7 in real time, providing a signal basis for anti-sway adjustment. By detecting the deflection of the clamping frame 7, the direction and amplitude of the sway are determined, thereby triggering corresponding adjustment actions. A passive adjustment mechanism 21 is provided between the clamping frame 7 and the mounting frame 5, used to buffer and offset small-amplitude swaying, reducing the impact of swaying on components and equipment, achieving passive anti-swaying without additional power. The first moving mechanism 2 can adjust the overall position of the upright 1, quickly locate the initial hoisting area, and improve the site adaptation efficiency in the early stage of the operation; then the second moving mechanism 4 adjusts the horizontal position of the clamping frame 7 to ensure that it is accurately aligned with the heavy component, and improve the positioning efficiency in the early stage of hoisting; during the movement of the mounting frame 5 by the second moving mechanism 4, the first motor 14 drives the first roller 13 to rotate, and the rolling friction between the roller and the guide rail drives the moving block 11 to slide along the first guide rail 10, so that the moving block 11 can move synchronously with the mounting frame 5, ensuring that the adjustment cable 17 is always in a proper tension state; the cable lifting mechanism 6 can smoothly lower the clamping frame 7 to above the component, and in conjunction with the hydraulic cylinder 9 drive the clamping arm 8 to retract, and the anti-slip teeth at the end of the clamping arm 8 enhance the friction with the component, which can firmly clamp the component and prevent the component from falling off during the hoisting process.When sensor 20 detects swaying of a component during lifting and handling due to wind load and its own movement, for swaying along the crossbeam 3, the second moving mechanism 4 drives the mounting frame 5 to move in the opposite direction of the swaying, quickly counteracting the swaying and maintaining stability in that direction. For swaying perpendicular to the crossbeam 3, if the swaying is small, the passive adjustment mechanism 21 can directly buffer and counteract it through its own structural deformation, reducing the impact on the equipment. If the swaying is large, sensor 20 detects that the sway amplitude exceeds a preset threshold and sends a signal to the control system. The corresponding side second motor 18 starts, and after being reduced in speed and torque by the first reducer 19, it drives the first cable reel 16 to rotate, causing it to retract or release the adjustment cable 17. The tension change of the cable pulls the component back to the preset position, effectively counteracting the swaying. Specifically, when the component sways violently to the left, the right-side second motor 18 drives the first cable reel 16 to rotate in the forward direction, tightening the adjustment cable 17. The pulling force of the cable pulls the component back to the right to the equilibrium position, and vice versa. Figure 5 and Figure 6As shown, the passive adjustment mechanism 21 includes multiple telescopic rods 60 disposed below the mounting frame 5. The telescopic rods 60 are hydraulic telescopic rods 60, used to adapt to minor vertical displacements of the clamping frame 7 and buffer vertical vibrations. Below the rods is a mounting plate 61, made of Q355B steel, used to mount the first rod body 62, providing a rotational reference for the passive adjustment mechanism 21. The first rod body 62, made of 45# steel, is rotatably connected below the mounting plate 61 and is used to transmit the force of the swaying motion, causing the spring 67 to deform through rotation and sliding. A guide rod 63, also made of 45# steel, is slidably connected below the first rod body 62, used to achieve a sliding connection between the first rod body 62 and the second rod body 64, providing movement space for the deformation of the spring 67. The other end of the guide rod 63 is fixedly connected to the second rod body 64, and the second rod body 64 is made of the same material as the first rod body 62. The first rod 62 is made of the same material and is used to connect the clamping frame 7 and the guide rod 63, transmitting the shaking of the clamping frame 7 to the guide rod 63 and the spring 67. The second rod 64 is rotatably connected to the clamping frame 7 to ensure flexible rotation during shaking. The side of the first rod 62 is provided with a first protruding ring 65, which is integrally formed with the first rod 62 and is used to limit the position of one end of the spring 67, providing a force support point for the spring 67. The outer side of the second rod 64 is provided with a second protruding ring 66, which is integrally formed with the second rod 64 and is used to limit the position of the other end of the spring 67, and to fix the spring 67 in conjunction with the first protruding ring 65. A spring 67 is provided between the second protruding ring 66 and the first protruding ring 65. The spring 67 is a high-strength compression spring, which is used to provide elastic restoring force, buffer shaking and drive reset. The spring 67 surrounds the outer side of the guide rod 63 and the first rod 62 to prevent the spring 67 from shifting. When the clamping frame 7 shakes, the passive adjustment mechanism 21 causes the second rod 64 to rotate relative to the clamping frame 7, while the first rod 62 rotates relative to the mounting plate 61. The guide rod 63 slides along the inside of the first rod 62, causing the spring 67 to undergo compression or tension deformation between the first convex ring 65 and the second convex ring 66. The spring 67, using its own elastic potential energy, quickly generates a restoring force opposite to the direction of shaking, pushing the guide rod 63, the first rod 62, and the second rod 64 to reset, thereby driving the clamping frame 7 back to the equilibrium position, thus passively reducing shaking. Figure 7As shown, the first moving mechanism 2 includes multiple first mounting seats 30 disposed below the upright frame 1. The first mounting seats 30 are welded from Q355B steel plates and are used to mount second mounting seats 31, providing mounting support for the moving wheel assembly. Second mounting seats 31 are symmetrically arranged at the front and rear ends of the first mounting seats 30. The second mounting seats 31 are made of the same material as the first mounting seats 30 and are used to mount second rollers 32, a second reducer 33, and a third motor 34, providing an integrated mounting carrier for the moving components. Second rollers 32 are symmetrically arranged at the front and rear ends of the second mounting seats 31. Solid rubber wheels support the overall weight of the equipment and enable movement, rolling to move the equipment on the ground. A second reducer 33, a worm gear reducer, is located on the side of the second mounting base 31. This reducer reduces the motor speed and increases the output torque, ensuring sufficient driving force for the second roller 32. A third motor 34, a variable frequency motor, is located at the input end of the second reducer 33, providing the power to rotate the second roller 32. The output end of the second reducer 33 is connected to the second roller 32 at the front end of the second mounting base 31. When the third motor 34 starts operating, the rotational power of its output shaft is transmitted to the input end of the second reducer 33. After the internal gear transmission of the second reducer 33 reduces the speed and increases the torque, the power is transmitted from the output end to the second roller 32, causing it to rotate and thus driving the frame 1 and the entire equipment to move along the ground. Figure 4 and Figure 8As shown, the second moving mechanism 4 includes a second guide rail 40 symmetrically arranged inside the crossbeam 3. The second guide rail 40 is a linear guide rail, used to guide the third roller 42 and ensure that the mounting frame 5 moves smoothly along the crossbeam 3. Multiple third mounting seats 41 symmetrically arranged on both sides of the mounting frame 5 are made of Q355B steel plate and used to mount the third roller 42, the third reducer 43, and the fourth motor 44, providing a mounting carrier for the moving drive components. The outer side of the third mounting seat 41 is provided with a third roller 42, which is a bearing-type roller, used to reduce the frictional resistance between the mounting frame 5 and the second guide rail 40, allowing the mounting frame 5 to move smoothly along the second guide rail 40. The lower part of the roller 42 abuts against the second guide rail 40. The inner side of the third mounting seat 41 is provided with a third reducer 43, which is a planetary gear reducer. A wheel reducer is used to reduce the motor speed and increase the output torque to ensure that the third roller 42 receives sufficient driving force. A fourth motor 44, a servo motor, is installed at the input end of the third reducer 43 to provide horizontal movement power and drive the third roller 42 to rotate. The output end of the third reducer 43 is connected to the third roller 42. The fourth motor 44 starts operation, and the rotational power of its output shaft is transmitted to the input end of the third reducer 43. After being reduced in speed and increased in torque by the third reducer 43, the output end drives the third roller 42 to rotate. Friction is generated between the third roller 42 and the second guide rail 40, which drives the third mounting base 41 and mounting bracket 5 to move horizontally along the second guide rail 40. By controlling the forward and reverse rotation and speed of the fourth motor 44, the movement direction and position of the mounting bracket 5 can be precisely adjusted. Figure 4 and Figure 8As shown, the cable lifting mechanism 6 includes multiple second cable reels 50 mounted on the mounting frame 5. The second cable reels 50 are welded from Q355B steel plates and are used to load and unload the lifting cable 53, controlling the lifting of the clamping frame 7. Multiple first fixed pulleys 51, symmetrically arranged on both sides of the mounting frame 5, are cast steel pulleys used to change the force direction of the lifting cable 53, guide its direction, and reduce friction between the cable and the mounting frame 5. Multiple second fixed pulleys 52, symmetrically arranged on both sides of the upper end of the clamping arm 8, are of the same specifications as the first fixed pulleys 51 and are used to assist in changing the direction of the lifting cable 53, ensuring that the cable tension is evenly transmitted to the clamping frame 7 and preventing the clamping frame 7 from tilting. The second cable reels 50 are equipped with the lifting cable 53. High-strength steel wire rope is used to support the weight of the clamping frame 7 and heavy components, and the vertical lifting of the clamping frame 7 is achieved by winding and unwinding. The lifting cable 53 is connected to the mounting frame 5 after passing through the first fixed pulley 51 and the second fixed pulley 52 on the same side. Through the guiding action of the fixed pulleys, the tension direction of the cable is consistent with the lifting direction of the clamping frame 7. The mounting frame 5 is equipped with multiple fourth reducers 54, which are planetary gear reducers, used to reduce the motor speed and increase the output torque to ensure that the second cable reel 50 obtains sufficient torque to wind and unwind the cable. The input end of the fourth reducer 54 is equipped with a fifth motor 55, which is a servo motor, used to provide lifting drive power to drive the second cable reel 50 to rotate. The output end of the fourth reducer 54 is connected to the second cable reel 50. The fifth motor 55 drives the fourth reducer 54 to operate. The high-speed, low-torque power output by the fifth motor 55 is converted into low-speed, high-torque power after being transmitted through the internal gears of the fourth reducer 54. This power is then transmitted to the second cable reel 50, causing it to rotate forward or backward. This causes the lifting cable 53 on the reel to retract or extend. The tension of the cable is used to control the raising or lowering of the clamping frame 7, thus enabling the vertical lifting and lowering of heavy components.

[0019] Working principle: During the hoisting and transportation of components, a combination of active and passive methods is used to reduce swaying caused by wind load and self-sway: when sensor 20 detects swaying along the direction of the crossbeam 3, the fourth motor 44 of the second moving mechanism 4 responds quickly, driving the mounting frame 5 to move in the opposite direction of the swaying, directly counteracting the swaying in that direction; when swaying is detected in the direction perpendicular to the crossbeam 3, if the swaying amplitude is small, the first rod 62 of the passive adjustment mechanism 21 rotates relative to the mounting plate 61, and the second rod 64 rotates relative to the clamping frame 7. The guide rod 63 slides along the first rod 62 and squeezes or stretches the spring 67. The spring 67 generates a reverse restoring force through its own elasticity, buffering and counteracting the swaying; if the swaying amplitude is large, sensor 20 sends a signal to the control system, the second motor 18 on the corresponding side starts, and the power is transmitted to the first cable reel 16 through the first reducer 19. The reel retracts or releases the adjustment cable 17, and the component is pulled back to the equilibrium position by the cable tension.
