Description

Technical Field

[0001] This invention relates to the field of aircraft hoisting and transportation technology, specifically to an aircraft unhooking device and its usage method. Background Technology

[0002] In recent years, rotorcraft (hereinafter referred to as "aircraft") have been increasingly used in material transportation, solving the problem that traditional transportation methods are temporarily inconvenient to implement. However, the connection and detachment of materials from aircraft is very inconvenient, and this process usually involves the following methods:

[0003] Method 1: The aircraft flies to and lands next to the goods to be hoisted. The aircraft's propellers are stopped, and ground personnel connect one end of the hoisting rope to the goods and the other end to the hook below the aircraft. The aircraft then takes off, hoisting the goods to the destination. Upon arrival, the aircraft descends to allow the goods to land, then lands next to the goods. The propellers are stopped, and ground personnel remove the hoisting rope from the hook below the aircraft, completing one transport trip. Alternatively, upon arrival, the aircraft can be remotely controlled to release the hook, detaching the hoisting rope from the aircraft and allowing the goods to fall to the ground. Alternatively, a configuration can be used where the hook automatically disengages upon landing.

[0004] Method 1 has the following problems: In order to avoid injury from the aircraft propeller, the aircraft needs to land next to the supplies and stop the propeller rotation. This landing and stopping action consumes time, which has a significant impact on efficiency, especially when multiple round trips are required. If the aircraft does not land and directly unhooks, the supplies will fall to the ground, which is not suitable for transporting easily damaged supplies. The method of equipping the hook with automatic unhooking after the heavy object lands is much better than the previous method, but it still requires releasing a long hoisting rope, and this device can only unhook, not automatically hook up.

[0005] Method 2: A remote-controlled sling is installed beneath the aircraft. After the aircraft flies to and hovers at a certain height directly above the goods to be transported, the remote-controlled sling releases the sling end to the goods. To prevent the aircraft from accidentally falling and injuring personnel below, the aircraft flies a certain distance away from the goods and then hovers (keeping the sling end at the goods during this time). At this point, ground personnel connect the sling end to the goods. The aircraft then flies back to directly above the goods, simultaneously winding up the sling to the appropriate length and lifting the goods to the destination. Upon reaching the destination, the aircraft hovers at an appropriate height, the remote-controlled sling releases the sling, and the goods descend until they land. The aircraft flies a certain distance away from the goods and then hovers. At this point, ground personnel disconnect the sling end from the goods, and the aircraft winds up the sling, completing one transport mission.

[0006] Method 2 has the following problems: the aircraft moves away from and flies back directly above the materials to be transported, which reduces the efficiency of the operation. There is also a risk that the hoisting rope may be too slack and blown up, entangled in the propeller blades, causing the aircraft to fall. In addition, when the ground support personnel operate the hoisting rope to connect or disconnect from the materials, pulling on the hoisting rope has a significant impact on the hovering aircraft, which may cause the aircraft to fall due to abnormal force.

[0007] Therefore, in order to solve the above problems, it is necessary to develop an aircraft unhooking device with high operational efficiency and safety reliability. Summary of the Invention

[0008] The technical problem solved by this invention is to address the shortcomings of existing technologies by proposing an aircraft unhooking device and its usage method. Through the adjustment mechanism and unhooking mechanism between the suspending frame assembly, the suspending rope, and the suspending tool, the invention solves the problems of low operation efficiency and safety reliability of traditional hoisting methods.

[0009] This invention is achieved through the following technical solution:

[0010] An aircraft unhooking device includes a sling, a sling assembly, and a lifting device;

[0011] One end of the lifting device is connected to the aircraft. The lifting frame assembly includes a lifting fork and multiple outriggers. The middle of the lifting fork is provided with a hook release mechanism that matches the other end of the lifting device. The outer peripheral sidewall of the lifting fork is connected to multiple outriggers through an adjustment mechanism, which allows the outriggers to be freely extended or retracted.

[0012] The two ends of the hoisting rope are respectively connected to the goods to be transported and the end of the outrigger.

[0013] In this solution, one end of the lifting rope is connected to the goods to be transported, and the other end is connected to the outrigger of the lifting frame assembly. The hook-and-unhook mechanism on the lifting frame assembly can freely engage with the lifting device during transport or freely disengage during unloading. Furthermore, the outer periphery of the lifting fork of the lifting frame assembly is connected to the outrigger through an adjustment mechanism, allowing the outrigger to freely extend when not lifting and freely retract during lifting. This achieves the goal of connecting and disengaging the aircraft lifting device from the transported goods without the need for ground personnel, thus solving the problems of low efficiency and safety reliability of traditional methods.

[0014] As a further technical solution of the aircraft unhooking device, the sling includes a first sling and a second sling, the end of each outrigger is connected to the second sling via a shackle, and the free end of the second sling is connected to the first sling via a rotary connector.

[0015] In this solution, since the materials will rotate after being lifted, in order to prevent the accumulated torque of the first lifting rope from being transmitted upwards and causing multiple second lifting ropes to become tangled, resulting in the outriggers being unable to deploy properly and thus causing unloading failure, the free ends of the second lifting ropes are all connected to the first lifting ropes through a rotary connector. The rotary connectors are used to counteract the accumulated torque of the first lifting ropes.

[0016] As a further technical solution of the aircraft unhooking device, the adjustment mechanism includes a return spring, the outer peripheral sidewall of the fork is provided with a plurality of small connecting lugs, the outer peripheral sidewall of the outrigger is provided with a hanging plate corresponding to the small connecting lugs, and the two ends of the return spring are respectively connected to the small connecting lugs and the hanging plate, providing elastic force for the outrigger to extend or retract.

[0017] In this design, multiple small connecting lugs are evenly welded to the outer periphery of the lifting fork, and hanging plates corresponding to the small connecting lugs are welded to the outer periphery of the outriggers. The two ends of the return spring are connected to the small connecting lugs and the hanging plates respectively, providing elastic force for the outriggers to extend or retract. When the outriggers retract, the storage space can be reduced or the cargo to be transported can be kept on a vertical line with the center of gravity of the aircraft.

[0018] As a further technical solution of the aircraft unhooking device, the adjustment mechanism also includes a double fork, with a large connecting lug at the top of the outrigger, the double fork being connected to the lower surface of the fork, and a groove matching the large connecting lug being provided in the middle of the double fork, and the top of the outrigger being able to rotate freely in the groove.

[0019] In this design, the top of the outrigger is movably connected to the lifting fork via a double fork, making the deployment or retraction of the outrigger more stable and reliable compared to a hinged connection.

[0020] As a further technical solution for the aircraft unhooking device, a stop block is connected to the side wall of the double-forked groove.

[0021] In this design, a stop block is positioned on the side wall of the double-fork groove, i.e., in the direction of the outrigger's rotation, to limit the outrigger's unfolding angle. When needed, the position of the stop block on the side wall of the groove can be adjusted to regulate the maximum unfolding angle of the outrigger.

[0022] As a further technical solution for the aircraft unhooking device, the side wall of the double-forked groove is provided with a through first limiting hole, and the large connecting lug is provided with a second limiting hole that matches the first limiting hole.

[0023] In this solution, after the aircraft unhooking device is used, in order to prevent the outriggers from swaying randomly, limiting pins are inserted into the first and second limiting holes to fix the outriggers in the vertical direction and reduce the storage space required for the entire device.

[0024] As a further technical solution for the aircraft unhooking device, the outer peripheral sidewall of the outrigger is provided with a storage hole corresponding to the second limiting hole.

[0025] In this design, to prevent the limit pin from being lost, the outer peripheral sidewall of the outrigger is provided with a storage hole corresponding to the second limit hole. When the aircraft unhooking device is in use, the removed limit pin can be inserted into the storage hole.

[0026] As a further technical solution of the aircraft unhooking device, the unhooking mechanism includes a connector, the middle of which is provided with an outer ring and an inner ring that match the lifting device, and the side wall of the connector is provided with a flared opening that communicates with the outer ring and the inner ring.

[0027] In this design, the connector has an outer ring and an inner ring that match the lifting device in the middle. That is, the connector has a stepped hole in the middle. The lifting device obtains support through the stepped hole. The side wall of the connector has a flared opening that communicates with the outer ring and the inner ring. The flared opening has an outward spreading section and a contracting section facing the middle of the connector, so that the lifting device can easily enter the connector through the flared opening.

[0028] As a further technical solution for the aircraft unhooking device, the horn opening is provided with an outwardly extending guide rod.

[0029] In this design, the guide rod extends outward along the flared end of the spreader section. The guide rod is used to further position the spreader and improve the connection efficiency between the spreader and the connector.

[0030] A method for detaching an aircraft from its hook, comprising the following steps, using any one of the above-described technical solutions:

[0031] S1. Preparation: First, bundle or pack the goods to be transported, then place the sling assembly in a suitable position, and connect the bundled or packed goods to the outriggers of the sling assembly via sling ropes. Finally, notify the pilot to connect the sling rope end to the aircraft attachment point.

[0032] S2. Positioning: Based on the video transmitted back by the aircraft's camera and in conjunction with the instructions of the ground support personnel via walkie-talkie, the pilot first locates the position of the pylon assembly, then assesses the basic conditions around the pylon assembly, and controls the aircraft to descend so that the pylon is hooked to the pylon assembly via the hook-off mechanism;

[0033] S3. Lifting: The pilot controls the aircraft to ascend, and the outriggers of the rigging assembly automatically close under the weight of the materials to be transported through the adjustment mechanism, so that the materials or devices to be transported are kept on a vertical line with the center of gravity of the aircraft. Then the pilot controls the aircraft to lift the materials to the destination.

[0034] S4. Unloading: Upon arrival, ground support personnel direct the descent of the aircraft to land the cargo. After the weight is removed, the outriggers of the rigging assembly automatically deploy through the adjustment mechanism. The pilot controls the aircraft to descend based on the video transmitted from the aircraft's camera, and the rigging is detached from the rigging assembly through the unhooking mechanism. The above steps are repeated to complete the next lifting process.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] This invention provides an aircraft unhooking device. The unhooking mechanism on the jack assembly allows the aircraft to be freely hooked to or unhooked from the lifting equipment during transport or unloading. Furthermore, the outer periphery of the lifting fork of the jack assembly is connected to the outriggers via an adjustment mechanism, allowing the outriggers to be freely extended when not lifting and freely retracted during lifting. This achieves the goal of connecting and detaching the aircraft lifting equipment from the transported goods without the need for ground personnel, while also reducing the requirements for the site and environment needed for connecting and detaching the aircraft lifting equipment from the transported goods.

[0037] This invention provides a method for detaching an aircraft from its hook. By having the adjustment mechanism and detachment mechanism between the jack assembly, the sling, and the lifting device work together, the lifting method improves operational efficiency and safety and reliability compared to existing technologies.

[0055] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0056] Example 1

[0057] This embodiment 1 provides an aircraft unhooking device, such as Figures 1-2As shown, the system includes a sling, a sling assembly 5, and a lifting device 7. One end of the lifting device 7 is connected to the aircraft. The sling assembly 5 includes a fork 51 and three outriggers 52. The fork 51 has a hook-off mechanism in the middle that matches the other end of the lifting device. The outer sidewall of the fork 51 is connected to the three outriggers 52 through an adjustment mechanism. The adjustment mechanism allows the outriggers 52 to be freely extended or retracted. The two ends of the sling are connected to the material to be transported 1 and the ends of the outriggers 52, respectively. Through the adjustment mechanism and hook-off mechanism between the sling assembly 5, the sling, and the lifting device 7, the connection and disconnection between the aircraft lifting device 7 and the transported material can be achieved without the intervention of ground personnel.

[0058] Please refer to Figure 1 and Figure 4 As shown, the above-mentioned suspension rope includes a first suspension rope 2 and three second suspension ropes 4 of equal length. The outrigger 52 includes a support rod 525, a hanging piece 526, and a foot support 527. The end of each support rod 525 is welded with a hanging piece 526 and a foot support 527. The second suspension ropes 4 and the shackles 8 are connected through the hanging pieces 526. The foot support 527 is used to provide stable support for the suspension frame assembly 5. The free ends of all the second suspension ropes 4 are connected to the first suspension rope 2 through a rotary connector 3 to prevent the accumulated torque of the first suspension rope 2 from being transmitted upwards, causing multiple second suspension ropes 4 to become tangled and preventing the outrigger 52 from being properly deployed.

[0059] Please refer to Figures 2-4 As shown, the adjustment mechanism includes a return spring 54 and a double fork 517. Three connecting ribs 520 are evenly distributed on the outer peripheral sidewall of the lifting fork 51. A small connecting lug 519 is welded to the outer sidewall of each connecting rib 520. A double fork 517 is welded below each connecting rib 520. Each double fork 517 is movably connected to a support leg 52. A hanging plate 524 corresponding to the small connecting lug 519 is welded to the outer peripheral sidewall of each support leg 52. The two ends of the return spring 54 are connected to the small connecting lug 519 and the hanging plate 524 respectively, providing elastic force for the extension or retraction of the support leg 52.

[0060] In this embodiment, a large connecting lug 523 is welded to the top of each support rod 525, and a groove matching the large connecting lug 523 is provided in the middle of the double fork 517. The large connecting lug 523 at the top of the support leg 52 can rotate freely in the groove, and the large connecting lug 523 and the double fork 517 are connected by the locking bolt 6 to prevent them from falling off. This method is more stable and reliable than the traditional hinge method.

[0061] Meanwhile, in order to limit the unfolding angle of the outrigger 52, a stop 516 is connected to the side wall of the groove of the double fork 517. The stop 516 is located in the rotation direction of the outrigger 52. When needed, the position of the stop 516 on the side wall of the groove can be adjusted to adjust the maximum unfolding angle of the outrigger 52.

[0062] In this embodiment, please refer to Figure 2 , Figure 4 as well as Figure 6 As shown, to prevent the outrigger 52 from wobbling freely after the aircraft's unhooking device is used, a first limiting hole 518 is provided through the side wall of the groove in the double fork 517, and a second limiting hole 521 matching the first limiting hole 518 is provided on the large connecting lug 523. By inserting a limiting pin 53 into the first limiting hole 518 and the second limiting hole 521, the outrigger 52 is fixed in the vertical direction, thereby reducing the storage space required for the entire device. Figure 6 As shown; simultaneously, a receiving hole 522 corresponding to the second limiting hole 521 is provided on the outer peripheral side wall of the support rod 525. When the aircraft unhooking device is in use, the removed limiting pin 53 can be inserted into the receiving hole 522, as shown. Figure 2 As shown, this is to prevent the limit pin 53 from being lost.

[0063] Meanwhile, please see Figure 2 and Figure 3 As shown, the aforementioned hook release mechanism includes a connector 511. The connector 511 has an outer ring 512 and an inner ring 513 at its center that match the lifting device 7. Furthermore, the side wall of the connector 511 has a flared opening 514 that communicates with the outer ring 512 and the inner ring 513. See details [link to documentation]. Figure 5 As shown, the lifting device 7 includes a third lifting rope 71, a lifting eye bolt 72, a lower lifting plate 73, and an upper lifting plate 74. The lower lifting plate 73 and the upper lifting plate 74 are matched with the outer ring 512 and the inner ring 513, respectively. One end of the third lifting rope 71 is connected to the aircraft, and the other end is connected to the upper lifting plate 74 through the lifting eye bolt 72. The third lifting rope 71 enters the outer ring 512 and the inner ring 513 through the flared opening 514, ultimately lifting the lifting assembly 5.

[0064] In addition, in this embodiment, the above-mentioned flared opening 514 is provided with an outwardly extending guide rod 515. The guide rod 515 extends outward along the diffusion section of the flared opening 514. The guide rod 515 is used to further position the lifting device 7 and improve the connection efficiency between the lifting device 7 and the connector 511.

[0065] Example 2

[0066] This embodiment 2 provides a method for detaching an aircraft from its hook. This method uses an aircraft detachment device described in embodiment 1 and includes the following steps:

[0067] S1. Preparation: First, bundle or pack the materials to be transported 1, then place the rigging assembly 5 in a suitable position, and connect the bundled or packed materials to be transported 1 to the rigging assembly 5 through the first rigging rope 2 and the second rigging rope 4. Finally, notify the pilot to connect the end of the third rigging rope 71 to the aircraft attachment point.

[0068] S2. Positioning: Based on the video transmitted by the aircraft's camera and in conjunction with the instructions from ground support personnel via walkie-talkie, the pilot first locates the position of the pylon assembly 5, then assesses the basic conditions around the pylon assembly 5, and maneuvers the aircraft to descend, bringing the lifting device 7 close to the guide rod 515. The pilot then maneuvers the aircraft horizontally, guiding the lifting device 7 along the flare opening 514 into the outer ring 512 and inner ring 513 of the pylon assembly 5. Figures 7 to 9 As shown;

[0069] S3. Lifting: The pilot controls the aircraft to ascend, and the outriggers 52 of the pylon assembly 5 automatically close under the weight of the cargo 1 via an adjustment mechanism. Figure 10 As shown, the cargo or device to be transported is kept on a vertical line with the center of gravity of the aircraft, and then the pilot controls the aircraft to hoist the cargo to the destination.

[0070] S4. Unloading: Upon arrival, ground support personnel direct the descent of the aircraft, allowing the cargo 1 to land first. As the first and second lifting ropes 2 and 4 slacken, the outriggers 52 of the sling assembly 5 automatically deploy via the return springs 54 after the weight is removed. The pilot, using video transmitted from the aircraft's camera, controls the aircraft to descend, causing the lifting device 7 to detach from the sling assembly 5 through the horn opening 514. The above steps are repeated to complete the next lifting operation.
