[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a wind-resistant hoisting device for building construction provided in one embodiment of the present invention includes: The hoisting truss 3 has a sliding mounting seat slidably disposed on it, and a support frame 15 is rotatably mounted on the sliding mounting seat. The support frame 15 is driven by a rotation control component. A lifting assembly is fixedly installed on the sliding mounting base. The lifting assembly includes a lifting cable 10 and a connecting base 1. The connecting base 1 is used to connect a hook. A dual-axis motor 4 is installed on the support frame 15. The output shaft of the dual-axis motor 4 is connected to a reel 5 through a clutch 11. A side support plate is fixedly installed on the support frame 15. The end of the reel 5 away from the dual-axis motor 4 is rotatably connected to the side support plate through a short shaft. Multiple sets of fixed fins 16 are fixedly provided at the end of the reel 5 away from the dual-axis motor 4. The fixed fins 16 are evenly distributed. A set of hollow sleeves is fixedly provided on the side support plate. The hollow sleeves are sleeved around the short shaft. An electromagnet 20 is fixedly installed on the hollow sleeves. A set of magnetic rings 19 are also slidably provided on the hollow sleeves. Movable fins 17 are fixedly installed on the magnetic rings 19. Multiple sets of guide fins 18 are also fixedly provided on the hollow sleeves. The guide fins 18 and the movable fins are spaced apart. A wind-resistant cable 2 is wound on the reel 5. The wind-resistant cable 2 is connected to the connecting base 1. A wind direction monitoring component is fixedly installed on the connecting base 1. The wind direction monitoring component is used to detect real-time wind direction and real-time wind force. During hoisting, wind force is monitored using a wind force monitoring component, and the traction direction of the wind-resistant cable 2 is adjusted based on the monitoring results.

[0018] In this embodiment, during the construction operation, the goods are fixed to the hook by installing the hook on the connecting base 1. At this time, the wind direction monitoring component installed on the connecting base 1 detects the real-time wind direction and wind force of the goods, thereby obtaining wind direction and wind force information. Based on the above information, the support frame 15 is rotated by the rotation control component, so that the pointing direction of the support frame 15 is consistent with the wind direction. At this time, the plane formed by the wind-resistant cable 2 is also consistent with the wind direction. At this time, the wind-resistant cable 2 on the windward side is tensioned, so that the lifting cable 10 tilts towards the windward side. At this time, the goods to be lifted cannot move with the wind direction, thus ensuring the stability of the lifting. In the process of controlling the wind-resistant cable 2, two sets of reels 5 are used to wind and release the two sets of wind-resistant cables 2 respectively. In this embodiment, a set of dual-axis motors 4 can realize the control of the two sets of reels 5. Taking one set of reels 5 as an example, when the reel 5 The end of the winding wheel 5 is provided with fixed fins. The magnetic ring 19 can slide back and forth relative to the hollow sleeve. When it is necessary to control the winding wheel 5, the corresponding output shaft of the dual-axis motor 4 is connected to the winding wheel 5 by controlling the clutch 11. At this time, the dual-axis motor 4 can realize the rotation control of the winding wheel 5. When it is not necessary to control the winding wheel 5, the winding wheel 5 is disconnected by the clutch 11. At this time, if the winding wheel 5 is not locked, the wind-resistant cable 2 will drive the winding wheel 5 to rotate, and the wind-resistant cable 2 will lose tension. At this time, the electromagnet 20 is energized, so that the electromagnet 20 repels the magnetic ring 19. The magnetic ring 19 then drives the movable fin 17 to move along the gap of the guide fin 18 towards the fixed fin 16 until the movable fin 17 and the fixed fin 16 cross each other. At this time, under the obstruction of the guide fin 18, the movable fin 17 and the magnetic ring 19 cannot rotate. Under the restriction of the movable fin 17, the winding wheel 5 also cannot rotate, so as to lock the winding wheel 5.

[0019] like Figure 1 and Figure 7As shown, in a preferred embodiment of the present invention, the wind direction monitoring component includes a wind vane 22 and a rotating base 21. The rotating base 21 is rotatably mounted on the connecting base 1, and the wind vane 22 is fixedly mounted on the rotating base 21. A set of second bevel gears 27 is rotatably mounted on the tail of the wind vane 22. A mounting bracket 23 is also fixedly mounted on the tail of the wind vane 22. A first rotating shaft and a second rotating shaft are rotatably mounted on the mounting bracket 23. The first rotating shaft and the second rotating shaft are coaxially arranged and located on both sides of the second bevel gear 27, respectively. A first bevel gear 26 is fixedly mounted on the first rotating shaft, and a third bevel gear 28 is fixedly mounted on the second rotating shaft. Both the first bevel gear 26 and the third bevel gear 28 mesh with the second bevel gear 27. A first wind-facing plate 24 is fixedly connected to the first rotating shaft, and a second wind-facing plate 25 is fixedly connected to the second rotating shaft. A guide groove 30 is provided on the rotating seat 21. A second sensing plate 31 and a first sensing plate 29 are fixedly connected to the first wind-facing plate 24 and the second wind-facing plate 25, respectively. A set of sliders is fixedly connected to both the second sensing plate 31 and the first sensing plate 29. The two sets of sliders are slidably arranged in the guide groove 30. A return spring is provided between the two sets of sliders. A coil spring is provided on both the first rotating shaft and the second rotating shaft. One end of the coil spring is fixedly connected to the mounting bracket 23.

[0020] In this embodiment, an angle sensor and a Hall element are provided on the rotating base 21. The angle sensor is used to monitor the rotation angle and direction of the wind vane. When the wind picks up, the first windward plate 24 and the second windward plate 25 are equivalent to two sets of deflectors. The two sets of deflectors are symmetrically arranged relative to the wind vane, so the wind vane will point to the windward side. At this time, the wind direction can be determined by the angle sensor and the Hall element. When the wind blows the first windward plate 24 and the second windward plate 25, the first windward plate 24 and the second windward plate 25 will rotate relative to each other. Since the first bevel gear 26 and the third bevel gear 28 are both meshed with the second bevel gear 27, the first windward plate 24 and the second windward plate 25 will rotate synchronously. When rotated, the first windward plate 24 and the second windward plate 25 will push the first sensing plate 29 and the second sensing plate 31 to move relative to each other, thereby changing the distance between them. The first sensing plate 29 and the second sensing plate 31 form a capacitor with a fixed sensing area and a fixed charge. The distance between the two sets of sensing plates can be calculated based on the generated potential. The current wind force level is calculated based on this distance value, and the tension of the wind-resistant cable 2 is determined based on the wind force level. When the wind force decreases, the first windward plate 24 and the second windward plate 25 will rebound under the action of the coil spring. Then the return spring in the guide groove 30 will drive the first sensing plate 29 and the second sensing plate 31 to move away from each other.

The worm 13 is driven by the rotary motor 12 and meshes with the worm gears 14.

[0022] In this embodiment, when the support frame 15 is rotated according to the wind direction, the rotary motor 12 is started, and the rotary motor 12 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 14 to rotate, and the worm wheel 14 directly drives the support frame 15 to rotate.

[0023] like Figure 1 and Figure 6 As shown, in a preferred embodiment of the present invention, an upper roller 6 and a lower roller 8 are rotatably provided on the sliding mounting base, and both the upper roller 6 and the lower roller 8 are rotatably connected to the hoisting truss 3.
