[0038] Combine the following Figures 1 to 12The invention describes a double-drive winch device for retracting and releasing the mooring line of an aerostat.

[0039] The present invention provides a dual-drive hoisting device for retracting and releasing aerostat mooring cables, comprising: a frame 100 , a drive module 200 and a hoisting module 300 , wherein the drive module 200 and the hoisting module 300 are both arranged on the frame 100 .

[0040] The driving module 200 includes a shell 210, a first driving motor 220, a second driving motor 230, a first clutch 240, a second clutch 250, a first rotating shaft 260 and a second rotating shaft 270. The output shaft of the first driving motor 220, the first clutch 240 and the first rotating shaft 260 are connected in sequence, the output shaft of the second driving motor 230, the second clutch 250 and the second rotating shaft 270 are connected in sequence, the first rotating shaft 260 and the second rotating shaft 270 are both rotatably connected to the shell 210, the first rotating shaft 260 and the second rotating shaft 270 are transmission-connected to drive the first rotating shaft 260 to rotate through the second driving motor 230, and the first rotating shaft 260 is transmission-connected to the winch module 300.

[0041] The dual-drive hoisting device for retracting and releasing the mooring line of an aerostat provided by the present invention is provided with a drive module 200. When both the first drive motor 220 and the second drive motor 230 in the drive module 200 are not faulty or the second drive motor 230 fails, the first drive motor 220 can be used to drive the first rotating shaft 260 to rotate and drive the hoisting module 300 to rotate via the first clutch 240 to realize the retracting and releasing of the mooring line. When the first drive motor 220 fails, the second drive motor 230 can be used to drive the second rotating shaft 270 to rotate via the second clutch 250. Since the second rotating shaft 270 is transmission-connected to the first rotating shaft 260, the rotation of the second rotating shaft 270 can drive the rotation of the first rotating shaft 260, thereby further driving the rotation of the hoisting module 300, so that the hoisting module 300 can normally retract and release the mooring line, ensure that the release of the aerostat is successfully completed, and improve the reliability of the release of the aerostat.

[0042] Specifically, the rack 100 in this embodiment is a rectangular frame structure, and the rack 100 is used to provide installation space and support for the drive module 200 and the hoisting module 300. The drive module 200, the hoisting module 300 and other components (such as the tension length measurement module 400, the rope guide module 500, the power supply module 600 and the electric control module 700 described below). The shape of the rack 100 is not limited to the rectangular frame structure, and the rack 100 can also be set to other structures according to actual needs.

[0043] The driving module 200 is used to drive the winch module 300 to work so as to realize the retraction and release of the rope. The driving module 200 includes a housing 210, a first driving motor 220, a second driving motor 230, a first clutch 240, a second clutch 250, a first rotating shaft 260 and a second rotating shaft 270. Among them, the first driving motor 220 is a main motor, and the second driving motor 230 is a backup motor. The first driving motor 220 can establish a transmission connection or a disengagement connection with the first rotating shaft 260 through the first clutch 240, and the second driving motor 230 can establish a transmission connection or a disengagement connection with the second rotating shaft 270 through the second clutch 250. The first rotating shaft 260 and the second rotating shaft 270 are in transmission connection, so that the first rotating shaft 260 and the second rotating shaft 270 can be mutually transmitted, so that any one of the first driving motor 220 or the second driving motor 230 drives the first rotating shaft 260 to rotate. The first clutch 240 and the second clutch 250 both use electromagnetic clutches, which have fast response speed and simple control.

[0044] The hoisting module 300 is used to store or release the lanyard, and the first rotating shaft 260 is connected to the hoisting module 300 in a transmission manner, so that the hoisting module 300 is driven to operate by the rotation of the first rotating shaft 260. The hoisting module 300 can be in the form of a drum or a winch. The drum 321 and the winch are both cylindrical devices, which can tighten and loosen the lanyard by rotating.

[0045] It should be noted that the first rotating shaft 260 and the hoisting module 300 can be directly connected or connected through a transmission mechanism / device. For example, when the first drive motor 220 and the second drive motor 230 are direct drive motors, the first rotating shaft 260 and the hoisting module 300 can be connected through a transmission mechanism / device to limit the operating speed of the hoisting module 300 within a preset range. When the first drive motor 220 and the second drive motor 230 are both reduction motors, the first rotating shaft 260 and the hoisting module 300 can be directly connected.

[0046] See also Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, a first gear 280 is disposed on the first rotating shaft 260 , and a second gear 290 is disposed on the second rotating shaft 270 , and the first gear 280 is meshed with the second gear 290 .

[0047] By setting a first gear 280 on the first rotating shaft 260 and a second gear 290 on the second rotating shaft 270, the first rotating shaft 260 and the second rotating shaft 270 are configured as a transmission connection, and transmission can be achieved by utilizing the meshing of the first gear 280 and the second gear 290. The structure is simple, the transmission accuracy is high, and the stability is strong.

[0048] It should be noted that the number of teeth of the first gear 280 and the second gear 290 can be set according to actual needs. For example, the number of teeth of the first gear 280 is greater than the number of teeth of the second gear 290, the number of teeth of the first gear 280 is equal to the number of teeth of the second gear 290, or the number of teeth of the first gear 280 is less than the number of teeth of the second gear 290.

[0049] In some embodiments, the first rotating shaft 260 and the second rotating shaft 270 may be configured to be in transmission connection through other transmission mechanisms, such as chain transmission or belt transmission.

[0050] According to some embodiments of the present invention, the first clutch 240 is a normally closed clutch, and the second clutch 250 is a normally open clutch.

[0051] Since the first drive motor 220 is the main motor and the second drive motor 230 is the backup motor, by setting the first clutch 240 to a normally closed clutch and the second clutch 250 to a normally open clutch, automatic switching between the main motor and the backup motor can be achieved, thereby improving the reliability and safety of the winch device.

[0052] Specifically, under normal working conditions, the first clutch 240 remains closed, the first drive motor 220 is connected to the first rotating shaft 260 and provides power to the hoisting module 300; meanwhile, the second clutch 250 remains disconnected, and the second drive motor 230 does not participate in the work. If the first drive motor 220 fails or needs to be shut down, the first clutch 240 can be disconnected and the second clutch 250 can be activated, so that the second drive motor 230 is connected to the first rotating shaft 260 through the second rotating shaft 270, takes over the power output, and ensures the uninterrupted operation of the hoisting device.

[0053] See also Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the winch module 300 includes a first mounting seat 310, a drum assembly 320 and a cable assembly 330; the drum assembly 320 includes a drum 321, and the drum 321 is rotatably disposed on the first mounting seat 310. The cable assembly 330 includes a bidirectional lead screw 331, a slide 332 and a cable wheel 333. The bidirectional lead screw 331 and the drum 321 are parallel to each other and are arranged at intervals. The bidirectional lead screw 331 is rotatably disposed on the first mounting seat 310. The bidirectional lead screw 331 is transmission-connected to the drum 321 to drive the bidirectional lead screw 331 to rotate through the drum 321. The slide 332 is disposed on the bidirectional lead screw 331 and can reciprocate along the length direction of the bidirectional lead screw 331. The cable wheel 333 is rotatably disposed on the slide 332.

[0054] By setting the winch module 300 in a form in which the drum assembly 320 and the cable arrangement assembly 330 cooperate, a more accurate and efficient arrangement of the cables can be achieved. The bidirectional lead screw 331 is arranged in parallel with the drum 321 to ensure stable power transmission. At the same time, the bidirectional lead screw 331 is connected to the drum 321 in a transmission manner, so that the slide 332 can reciprocate along the length direction of the bidirectional lead screw 331, thereby improving the flexibility and adaptability of the cable arrangement. The rotation setting of the cable arrangement wheel 333 makes the arrangement of the cables more uniform and smooth, reducing the risk of wear and failure.

[0055] Specifically, in this embodiment, the drum 321 and the bidirectional lead screw 331 are both horizontally mounted on the first mounting seat 310, and the stroke of the bidirectional lead screw 331 is consistent with the cable drum length of the drum 321. A drum shaft 334 is provided at one end of the drum 321, and the drum shaft 334 rotates synchronously with the drum 321 and is connected to the bidirectional lead screw 331 through a belt transmission mechanism. Of course, in some embodiments, the drum shaft 334 can also be connected to the bidirectional lead screw 331 through a gear transmission or a chain transmission.

[0056] See also Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the winch module 300 also includes a worm gear reducer 340 , the first rotating shaft 260 is drivingly connected to the input end of the worm gear reducer 340 , and the output end of the worm gear reducer 340 is drivingly connected to the drum 321 .

[0057] By arranging a worm gear reducer 340 between the first rotating shaft 260 and the drum 321, the transmission speed can be effectively reduced and the output torque can be increased, providing a greater driving force to drive the drum 321. The structural characteristics of the worm gear can achieve the switching of the output direction of the driving force, thereby improving the integration and compactness of the hoisting device. In addition, the design of the worm gear reducer 340 also has a self-locking function, which can prevent the hoisting device from rotating in the opposite direction when it is stopped, further improving stability and safety.

[0058] See also Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the dual-drive winch device for the retraction and deployment of the airship mooring also includes a tension length measuring module 400, the tension length measuring module 400 includes a second mounting seat 410, an axle pin type weighing sensor 420, a tension measuring wheel 430, a length measuring wheel 440 and a length measuring encoder 450, the second mounting seat 410 is arranged on the frame 100, the axle pin type weighing sensor 420 is rotatably arranged on the second mounting seat 410, the tension measuring wheel 430 is sleeved on the axle pin type weighing sensor 420, the length measuring wheel 440 is rotatably arranged on the second mounting seat 410, and the outer edge of the length measuring wheel 440 is engaged with the outer edge of the tension measuring wheel 430.

[0059] By providing the tension length measurement module 400, the tension of the mooring line wound on the drum 321 and the length of the mooring line can be measured and displayed, thereby realizing effective monitoring and control of the mooring line state of the aerostat. By meshing the tension measurement wheel 430 and the length measuring wheel 440, the tension and length of the mooring line can be synchronously measured, thereby realizing more accurate mooring line state monitoring.

[0060] Specifically, the principle of tension measurement is to install the pin-type weighing sensor 420 inside the tension measuring wheel 430, and use it as the supporting shaft of the tension measuring wheel 430. The lanyard passes through the tension measuring wheel 430. When the lanyard is stressed, the pin-type weighing sensor 420 will be deformed, and the actual tension on the lanyard is calculated by the wrap angle formed by the lanyard passing through the tension measuring wheel 430. The principle of length measurement is to install the length measuring wheel 440 on the top of the tension measuring wheel 430. The outer side of the rim of the length measuring wheel 440 is usually made of rubber material, which meshes with the outer edge of the tension measuring wheel 430. When the lanyard passes through the tension measuring wheel 430, the lanyard will drive the tension measuring wheel 430 to rotate, and the length measuring wheel 440 will rotate under the drive of the tension measuring wheel 430. The length measuring wheel 440 is installed on the length measuring encoder 450, and the rotation of the length measuring wheel 440 completes the rotation of the length measuring encoder 450, and the length measurement is completed.

[0061] See also Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, a rocker arm 460 is provided on the second mounting seat 410, and the length measuring wheel 440 is rotatably provided on the rocker arm 460. A tension spring 470 is provided between the rocker arm 460 and the second mounting seat 410 to press the length measuring wheel 440 against the tension measuring wheel 430.

[0062] By arranging the rocker arm 460 on the second mounting seat 410 and rotatably arranging the length measuring wheel 440 on the rocker arm 460, the tension spring 470 between the rocker arm 460 and the second mounting seat 410 can pull the rocker arm 460 downward and press the length measuring wheel 440 against the tension measuring wheel 430, thereby preventing a gap or slippage between the length measuring wheel 440 and the tension measuring wheel 430, thereby ensuring that the two are always closely meshed, avoiding measurement errors caused by poor contact, and ensuring that the length measuring wheel 440 always accurately records the length of the lanyard during the entire retraction and release process. In addition, the elastic effect of the tension spring 470 enables the length measuring wheel 440 to adjust the pressure in real time according to the changes in the tension measuring wheel 430, providing a stable contact force, enhancing the measurement accuracy and reliability of the system, while reducing mechanical wear and extending the service life of the equipment.

[0063] Specifically, see Figure 7As shown, a mounting shaft 480 is provided on the second mounting seat 410, one end of the rocker arm 460 is rotatably provided on the mounting shaft 480, and the length measuring wheel 440 is rotatably provided on the other end of the rocker arm 460. One end of the tension spring 470 is connected to the inner wall of the second mounting seat 410, and the other end is connected to the side wall of the rocker arm 460 to pull the rocker arm 460 downward and drive the length measuring wheel 440 downward.

[0064] See also Fig. 9 and Fig.10 As shown, according to some embodiments of the present invention, the dual-drive winch device for retracting and releasing the aerostat tether also includes a tether guide module 500, which includes a third mounting seat 510, a guide wheel 520 and an upper guide wheel 530. The third mounting seat 510 is rotatably disposed on the frame 100, and the guide wheel 520 and the upper guide wheel 530 are both rotatably disposed on the third mounting seat 510, and a space for the tether to pass through is formed between the guide wheel 520 and the upper guide wheel 530.

[0065] By providing the belay guide module 500, the movement path of the belay during the retraction and extension process can be effectively guided and controlled, ensuring that the belay is smoothly retracted and extended in the hoisting device.

[0066] Specifically, the lanyard guide module 500 fixes the guide wheel 520 and the upper guide wheel 530 on the frame 100 through the third mounting seat 510, so that the guide wheel 520 and the upper guide wheel 530 can rotate freely, thereby reducing the risk of entanglement, deviation or damage of the lanyard during the retraction and extension process. The space formed between the guide wheel 520 and the upper guide wheel 530 can limit the lanyard, so that the lanyard is always between the guide wheel 520 and the upper guide wheel 530 during the retraction and extension, preventing the lanyard from falling out.

[0070] See also Fig.12 As shown, according to some embodiments of the present invention, the dual-drive hoisting device for retracting and releasing the aerostat mooring line further includes an electric control module 700 , and the electric control module 700 is disposed on the frame 100 .

[0071] By setting up the electric control module 700, it is possible to communicate with the drive module 200, the winch module 300, the tension length measurement module 400 and the power supply module 600, so as to monitor and adjust the working status of each module in real time, so as to ensure the efficient and stable operation of the entire dual-drive winch device and realize coordination and precise control among the modules.

[0072] Specifically, the electric control module 700 includes an electric control operation panel, a controller, a charger and a communication interface. The controller is respectively connected to the communication interface, the first drive motor 220, the second drive motor 230 and the motor brake, and the charger is used to connect to the battery of the power supply module 600; the communication interface is used to connect to the electric control operation panel, and the electric control operation panel includes control buttons of the first drive motor 220 and the second drive motor 230, which are used to receive user operation instructions.

[0073] It can be seen from the description of the above embodiments that the dual-drive winch device for retracting and releasing the aerostat mooring provided by the present invention has at least the following advantages.

[0074] (1) The dual-drive hoisting device for retracting and releasing the mooring line of an aerostat provided by the present invention is provided with a drive module 200. When both the first drive motor 220 and the second drive motor 230 in the drive module 200 are not faulty or the second drive motor 230 is faulty, the first drive motor 220 can be used to drive the first rotating shaft 260 to rotate via the first clutch 240 and drive the hoisting module 300 to rotate, so as to realize the retracting and releasing of the mooring line. When the first drive motor 220 is faulty, the second drive motor 230 can be used to drive the second rotating shaft 270 to rotate via the second clutch 250. Since the second rotating shaft 270 is connected to the first rotating shaft 260 by transmission, the rotation of the second rotating shaft 270 can drive the rotation of the first rotating shaft 260, thereby further driving the rotation of the hoisting module 300, so that the hoisting module 300 can normally retract and release the mooring line, thereby ensuring that the release of the aerostat is completed smoothly, thereby improving the reliability of the release of the aerostat.

[0075] (2) The dual-drive hoisting device for the retraction and deployment of the aerostat mooring provided by the present invention adopts a compact frame-type hoisting device structure, which is easy to transport and install; the drum 321 device can be designed with a rope capacity according to actual needs, which is suitable for the retraction and deployment of the mooring of an aerostat with a length of more than tens of meters, and has stronger adaptability; it is equipped with a rope arrangement component to ensure that the mooring is arranged neatly to avoid entanglement, and is particularly suitable for the retraction and deployment of the aerostat mooring; the tension length measuring device can measure the tension and retraction length of the mooring in real time, which is convenient for adjusting the rope release length according to the actual tension; independent power supply and electronic control components are provided for the two sets of drive motors, which supports rapid switching, improves the reliability of the device, and ensures stable operation of the system.
