DETAILED DESCRIPTION
[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art without creative work based on the embodiments in the present application are within the scope of protection of the present application.
[0040] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0041] In the description of the present application, it should be noted that, if the terms “upper”, “lower”, “inner”, “outer” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the utility model product is usually placed, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.
[0042] In addition, if the terms “first”, “second” and the like appear, they are only used for differentiation description, and cannot be understood as indicating or implying relative importance.
[0043] It should be noted that, in the case of no conflict, the features in the embodiments of the present application can be combined with each other.
[0044] In the related art, the load bearing capacity of a single aircraft is limited, which makes it difficult to transport a single large weight cargo by using a single aircraft. If multiple aircrafts are used to jointly bear the cargo, the coordinated control between the aircrafts is difficult. When an aircraft produces uncoordinated action, such as lowering the flight height relative to other aircrafts, the weight borne by other aircrafts will increase significantly. For example, when the crew turns, the cargo will swing outward due to the centrifugal force, and the force borne by the aircraft close to the inner side will increase. Moreover, when the cargo swings due to external force, the uniformity of the force borne between the aircrafts will also be seriously affected. Therefore, the control of the multiple aircrafts in the prior art for jointly transporting the cargo is difficult, and the stability is poor.
[0045] Therefore, an embodiment of the present application provides a hanging device, which is matched with the lifting rope between the aircrafts by setting at least two groups of pulley assemblies, so that the hanging device can adaptively adjust the position relative to the lifting rope, thereby balancing the force borne by each aircraft, reducing the mutual influence between the aircrafts, reducing the control difficulty of the multiple aircrafts for jointly transporting the cargo, and improving the stability of the flight transportation system. In addition, an embodiment of the present application also provides a flight transportation system comprising the above hanging device.
[0046] Figure 1 FIG. 1 is a schematic view of a flight transportation system according to an embodiment of the present application. As shown in FIG. 1, the flight transportation system provided by the embodiment of the present application comprises at least two aircrafts 200, a lifting rope 300 and a hanging device 100, and each aircraft 200 is connected by the lifting rope 300 to form a closed loop. Figure 1 The hanging device 100 comprises a hanging body 110, a pulley mounting member connected to the hanging body 110, and at least two groups of pulley assemblies 120 mounted on the pulley mounting member. The pulley mounting member is used to mount the pulley assemblies, and each group of pulley assemblies 120 is used to connect two aircrafts 200 by the lifting rope 300. In other words, the lifting rope 300 between two adjacent aircrafts 200 is matched with the pulley assemblies 120 on the hanging device 100. The hanging body 110 of the hanging device 100 is used to connect the cargo, and the aircraft 200 can lift the cargo by the hanging device 100 and transport it.
[0047] Optionally, the number of pulley assemblies 120 on the hanging device 100 matches the number of aircrafts 200, and the lifting rope 300 between every two adjacent aircrafts 200 is connected to the hanging device 100 by one pulley assembly 120. In this way, the force borne by each aircraft 200 can be balanced, and the stability of the flight transportation system can be improved. Figure 1In the shown embodiment, the flight transportation system includes four aircrafts 200 in total, and four groups of pulley assemblies 120 are arranged on the suspension device 100. In other embodiments, the number of pulley assemblies 120 and the number of aircrafts 200 can be increased or decreased as needed; in alternative embodiments, the number of aircrafts 200 can also be less than the number of pulley assemblies 120, so that some pulley assemblies 120 are idle or the suspension rope 300 between two adjacent aircrafts 200 passes through more than two pulley assemblies 120. For example, Figure 1 In the shown embodiment, the number of aircrafts 200 can be two, which are symmetrically distributed around the suspension device 100.
[0048] It can be understood that when an aircraft 200 in the flight transportation system performs an uncoordinated flight action, such as sudden lifting or sudden lowering, the suspension rope 300 between the aircraft 200 and the adjacent aircraft 200 will naturally slip relative to the pulley assembly 120, so that the force between the aircraft 200 and the adjacent aircraft 200 tends to be balanced, avoiding the situation that one of the aircrafts 200 exceeds its own load. At the same time, through the suspension device 100 provided by the embodiments of the present application, the mutual influence between each aircraft 200 in the flight transportation system can be reduced, the difficulty of coordinated control of the aircraft 200 is reduced, and the stability of the flight transportation system is improved.
[0049] Alternatively, at least one aircraft 200 is provided with a traction pulley 210, and the aircraft 200 provided with the traction pulley 210 cooperates with the suspension rope 300 through the traction pulley 210. It should be understood that the part of the suspension rope 300 connected to the aircraft 200 through the traction pulley 210 can not have a rope head, but is directly wound on the traction pulley 210, so that the aircraft 200 and the suspension rope 300 are not fixed. When the suspension rope 300 connected to the aircraft 200 provided with the traction pulley 210 is unevenly stressed, the traction pulley 210 will roll relative to the suspension rope 300, adjusting the force point of the traction pulley 210 on the suspension rope 300, which can further reduce the influence of the uncoordinated action of the adjacent aircraft 200 on the aircraft 200.
[0050] Alternatively, the suspension rope 300 is one and has two ends, both ends of the suspension rope 300 are connected to the same aircraft 200, and the remaining aircrafts 200 are provided with traction pulleys 210 and cooperate with the suspension rope 300 through the traction pulleys 210. In other words, one end of the suspension rope 300 is connected to the initial aircraft 200, then alternately passes through the pulley assembly 120 and the other aircraft 200 with the traction pulley 210 along the extension direction of the suspension rope 300, and finally, the other end of the suspension rope 300 returns to the initial aircraft 200 and is fixedly connected thereto. In Figure 1 In the shown embodiment, the traction pulley 210 is arranged on the bottom surface of the aircraft 200. Figure 1The upper and middle aircraft 200 are fixedly connected with the two rope heads of the suspension rope 300, and the other three aircraft 200 are connected with the suspension rope 300 through the traction pulley 210.
[0051] Figure 2 It is a schematic diagram of the flight transportation system in another embodiment of the present application. As shown in the figure, the suspension rope 300 is in a ring shape, and each aircraft 200 is provided with a traction pulley 210, and each aircraft 200 is connected with the suspension rope 300 through the traction pulley 210. Figure 2 In the embodiment, each aircraft 200 can freely adjust the position acting on the suspension rope 300, so that the force acting on each aircraft 200 can be more balanced. Figure 2
[0052] It is a schematic diagram of the traction pulley 210 and the suspension rope 300 in an embodiment of the present application. As shown in the figure, the traction pulley 210 comprises a seat body 211, a traction member 213 and a roller 212, the roller 212 is rotatably connected to the seat body 211, and the traction member 213 is rotatably connected to the seat body 211, the traction member 213 is connected with the aircraft 200, and the roller 212 is connected with the suspension rope 300. Figure 3 As shown in the figure, the outer periphery of the roller 212 has a groove for embedding the suspension rope 300, so as to prevent the suspension rope 300 from being separated from the outer periphery of the roller 212. The seat body 211 is a U-shaped member, and a part of the roller 212 is embedded in the seat body 211 and rotatably connected with the seat body 211. The traction member 213 comprises a lifting ring 2131 and a rotation shaft 2132, the lifting ring 2131 is arranged on the rotation shaft 2132, and the rotation shaft 2132 is rotatably connected with the seat body 211. The lifting ring 2131 can be connected with the aircraft 200 through a rope or other connecting member, and by allowing the lifting ring 2131 to rotate relative to the seat body 211, the roller 212 can be prevented from being affected by the attitude of the aircraft 200, so that the roller 212 can keep tangent to the suspension rope 300, thereby reducing the wear of the suspension rope 300 and the risk of the suspension rope 300 being separated from the roller 212, and also making the rolling of the roller 212 more smooth. Figure 3 Figure 3 It should be understood that in other alternative embodiments, all the aircraft 200 can not be provided with the traction pulley 210, and each aircraft 200 is connected with two adjacent aircraft 200 through two ropes.
[0053] It is a schematic diagram of the suspension device 100 in an embodiment of the present application (one connecting member 113 is omitted);
[0054] It is a schematic diagram of the cooperation between the suspension device 100 and the suspension rope 300 in an embodiment of the present application; Figure 4 It is a schematic diagram of the suspension device 100 in an embodiment of the present application (one connecting member 113 is omitted); Figure 5 It is a schematic diagram of the cooperation between the suspension device 100 and the suspension rope 300 in an embodiment of the present application; Figure 6 It is a schematic diagram of the suspension device 100 in an embodiment of the present application (one connecting member 113 is omitted); Figure 5Enlarged view of a portion VI. Optionally, the suspension device 100 includes at least three sets of pulley assemblies 120, which are arranged circumferentially around the suspension body 110. In this embodiment, the suspension device 100 is described as having four sets of pulley assemblies 120. Figures 4 to 6 As shown, in this embodiment, each pulley assembly 120 includes at least two load-bearing pulleys 121 and at least one corner pulley 122. The corner pulley 122 is used to cooperate with the suspension rope 300 between the two load-bearing pulleys 121 to change the extension direction of the suspension rope 300. The load-bearing pulleys 121 receive the upward traction force from the suspension rope 300, so that the suspended body 110 can be lifted in the vertical direction. In this embodiment, each pulley assembly 120 includes two load-bearing pulleys 121 and one corner pulley 122. Since the two load-bearing pulleys 121 are subjected to the upward traction force of two different aircraft 200, the axes of the two load-bearing pulleys 121 in the same pulley assembly 120 are at an angle to accommodate the traction direction of the different aircraft 200. The function of the corner pulley 122 is to guide the suspension rope 300 between the two load-bearing pulleys 121 to rotate, so that the suspension rope 300 can remain tangent to or close to tangent to the two different load-bearing pulleys 121, reducing the wear of the suspension rope 300 and improving the smoothness of the load-bearing pulleys 121 rolling along the suspension rope 300. In other embodiments, the number of load-bearing pulleys 121 and corner pulleys 122 in the pulley assembly 120 can be increased as needed. For example, two or more load-bearing pulleys 121 can be arranged on each side of the corner pulley 122, and the number of corner pulleys 122 can also be two or more.
[0055] Optionally, the suspension body 110 is generally a regular polygon, with chamfered corners. The number of pulley assemblies 120 matches the number of sides of the regular polygon. Corner pulleys 122 of the pulley assemblies 120 are respectively located at the corners of the suspension body 110, and load-bearing pulleys 121 of the pulley assemblies 120 are distributed along the sides of the suspension body 110. The extension direction of the suspension rope 300 is changed after passing the corner pulleys 122. Specifically... Figures 4-6 In this embodiment, optionally, the suspension body 110 is generally square, and the pulley assembly 120 consists of four sets. The corner pulleys 122 of the four sets of pulley assemblies 120 are respectively arranged at the four corners of the suspension body 110, and the load-bearing pulleys 121 of the four sets of pulley assemblies 120 are distributed along the four sides of the suspension body 110. After passing the corner pulleys 122, the extension direction of the suspension rope 300 changes by 90°. Optionally, the load-bearing pulleys 121 are arranged close to the corners, so that each set of pulley assemblies 120 is concentrated at the four corners. However, this application is not limited to this. Alternatively, the load-bearing pulleys 121 of the four sets of pulley assemblies 120 can be distributed along the four sides of the square, and not close to the corners, as long as the force balance can be achieved.
[0056] In the embodiment, the hanging body 110 comprises a fixed body 111, the pulley mounting member comprises a first pulley mounting member 131 rotatably connected to the periphery of the fixed body 111, and the load bearing pulley 121 is arranged on the first pulley mounting member 131. During the flight of the aircraft 200 with the hanging device 100, the height of the aircraft 200 relative to the hanging device 100 can be changed, which can cause the inclination angle of the hanging rope 300 between the aircraft 200 and the pulley assembly 120 relative to the horizontal plane to be variable. For example, when the aircraft 200 is close to directly above the hanging device 100, the inclination angle between the hanging rope 300 between the aircraft 200 and the load bearing pulley 121 and the horizontal plane will be larger, and when the aircraft 200 is away from directly above the hanging device 100 in the horizontal direction, the inclination angle between the hanging rope 300 between the aircraft 200 and the load bearing pulley 121 and the horizontal plane will be smaller. In the embodiment, the first pulley mounting member 131 is arranged to be rotatable relative to the fixed body 111, so that the first pulley mounting member 131 and the load bearing pulley 121 can adaptively adjust the posture according to the current inclination angle of the hanging rope 300, so as to keep the load bearing pulley 121 tangent or close to tangent to the hanging rope 300, thereby ensuring the smoothness of the rolling of the load bearing pulley 121.
[0057] Optionally, the number of the first pulley mounting member 131 is consistent with the number of the pulley assembly 120, and two load bearing pulleys 121 are arranged on each first pulley mounting member 131, and the two load bearing pulleys 121 belong to two adjacent groups of pulley assemblies 120, respectively. Optionally, the axes of the two load bearing pulleys 121 on the same first pulley mounting member 131 are parallel. In the embodiment, the fixed body 111 is substantially square, and the number of the first pulley mounting member 131 is four, which are arranged on the four edges of the fixed body 111, respectively.
[0058] Optionally, the corner pulley 122 and the load-bearing pulley 121 belonging to the same pulley assembly 120 have a common tangent, and the common tangent coincides with the rotation axis of the first pulley mounting member 131. It can be understood that when the suspension rope 300 is tangent to the pulley, the pulley rolls most smoothly relative to the suspension rope 300. However, when the suspension rope 300 deviates from the tangent, wear or even jamming of the suspension rope 300 is likely to occur. In this embodiment, when the suspension rope 300 passes through the pulley assembly 120, it passes through one load-bearing pulley 121, the corner pulley 122, and another load-bearing pulley 121 in sequence. Therefore, in this embodiment, the corner pulley 122 and the load-bearing pulley 121 have a common tangent, allowing the suspension rope 300 to extend along the common tangent when passing through the load-bearing pulley 121 and the corner pulley 122, thus enabling both the corner pulley 122 and the load-bearing pulley 121 to rotate smoothly. Furthermore, the common tangent line coincides with the rotation axis of the first pulley mounting component 131, so that no matter how the first pulley mounting component 131 rotates, the corner pulley 122 and the load-bearing pulley 121 of the same pulley assembly 120 always have a common tangent line, and the position of the common tangent line remains unchanged. As a result, the hoisting rope 300 will never deviate from the common tangent line, and it is not easy to cause wear and jamming of the hoisting rope 300.
[0059] In this embodiment, the pulley mounting component further includes a second pulley mounting component 132, which is fixedly connected to the fixed body 111. Angle pulleys 122 are connected to the second pulley mounting component 132. Specifically, in this embodiment, four second pulley mounting components 132 are fixedly connected to the four corners of the fixed body 111. Optionally, when the hanging device 100 is placed horizontally, the second pulley mounting components 132 are arranged horizontally, the axes of the angle pulleys 122 are perpendicular to the second pulley mounting components 132, and the axes of each angle pulley 122 are parallel to each other.
[0060] Figure 7 This is a schematic diagram of connector 113 in one embodiment of this application; Figure 8 for Figure 4 A magnified view of section VIII in the middle. Combined with... Figures 4 to 8 In this embodiment, a connector 113 is provided on the fixed body 111, and the first pulley mounting member 131 is rotatably connected to the connector 113. The connector 113 is provided with a first abutment surface 1134 and a second abutment surface 1135 at an angle. The first abutment surface 1134 and the second abutment surface 1135 are respectively used to abut against the first pulley mounting member 131 when it rotates to two extreme positions. By providing the first abutment surface 1134 and the second abutment surface 1135 on the connector 113, the rotation angle travel of the first pulley mounting member 131 can be effectively limited.
[0061] Optionally, the connector 113 includes a first connecting portion 1131 and two second connecting portions 1132. The two second connecting portions 1132 are respectively connected to both ends of the first connecting portion 1131 to make the connector 113 U-shaped. The first connecting portion 1131 is connected to the fixed body 111, and the two second connecting portions 1132 are connected to the first pulley mounting member 131. Each second connecting portion 1132 has a first abutting surface 1134 and a second abutting surface 1135. Figure 7 As shown, the connector 113 is a one-piece molded plate, which is bent to form a first connecting part 1131 and two second connecting parts 1132; a first abutting surface 1134 and a second abutting surface 1135 are formed on the side of the second connecting part 1132. It can be understood that the included angle between the first abutting surface 1134 and the second abutting surface 1135 (…) Figure 7 The larger the angle (as shown in angle A), the smaller the rotation angle range of the first pulley mounting member 131, meaning a smaller rotation adjustment range for the first pulley mounting member 131; the smaller the angle between the first abutment surface 1134 and the second abutment surface 1135, the larger the rotation angle range of the first pulley mounting member 131. However, if the angle between the first abutment surface 1134 and the second abutment surface 1135 is too small, it will affect the structural strength of the connector 113. Therefore, considering both the adjustment range and the structural strength of the connector 113, the angle between the first abutment surface 1134 and the second abutment surface 1135 can optionally be between 60° and 120°. Specifically, assuming the hanging device 100 is placed horizontally and the first pulley mounting member 131 is rotated to the vertical direction, and the rotation angle of the first pulley mounting member 131 is considered to be 0°, then when the angle between the first abutment surface 1134 and the second abutment surface 1135 is 60°, the rotation angle range of the first pulley mounting member 131 is -60° to 60°; when the angle between the first abutment surface 1134 and the second abutment surface 1135 is 90°, the rotation angle range of the first pulley mounting member 131 is -45° to 45°; and when the angle between the first abutment surface 1134 and the second abutment surface 1135 is 120°, the rotation angle range of the first pulley mounting member 131 is -30° to 30°. Preferably, when the angle between the first abutment surface 1134 and the second abutment surface 1135 is 90°, the rotation angle range of the first pulley mounting member 131 is -45° to 45°.
[0062] Figure 9 and Figure 10 This is a schematic diagram of the first pulley mounting member 131 rotating to two extreme positions in one embodiment of this application. Figure 9 In the middle, the first pulley mounting part 131 is in the extreme position of being extended outwards. Figure 10 In the middle, the first pulley mounting component 131 is in its inwardly retracted limit position. The position of the first pulley mounting component 131 reflects the positional change of the aircraft 200 relative to the fixed body 111. Assuming at the same altitude, Figure 9 The position of the first pulley mounting component 131 indicates that the aircraft 200 is relatively far from the suspension device 100 in the horizontal direction; Figure 10 The position of the first pulley mount 131 reflects the horizontal distance between the aircraft 200 and the sling device 100. Since different aircraft 200s may have different positions relative to the sling device 100, multiple first pulley mounts 131 may also maintain different attitudes. In addition, changes in the altitude of the aircraft 200 and cargo swaying will also affect the angle between the first pulley mount 131 and the fixed body 111.
[0063] Please continue to refer to Figure 7 and Figure 8 In this embodiment, each first pulley mounting member 131 has two shafts 1311 spaced apart. The two second connecting portions 1132 of the connector 113 each have a shaft hole 1133. The two shafts 1311 are pivotally connected to their respective second connecting portions 1132 through the two shaft holes 1133. The first connecting portion 1131 has a mounting hole 1136, so the connector 113 can be fixedly connected to the fixing body 111 by bolts and the mounting hole 1136. In other embodiments, the connector 113 can also be welded to the fixing body 111 or integrally formed.
[0064] Furthermore, the connector 113 is provided with a connecting hole 1137, which is used to connect to the cargo rope. In this embodiment, the connector 113 not only connects to the first pulley mounting part 131, but also serves to suspend the cargo, which can be suspended below the suspending device 100 by the cargo rope. Figure 11 This is a schematic diagram of the hoisting device 100 connecting to the cargo rope in one embodiment of this application. Figure 11 As shown, specifically, a first cargo rope 410 can be connected to each of the multiple connectors 113. The ends of the four first cargo ropes 410 converge and connect to a second cargo rope 420. The second cargo rope 420 is connected to the cargo, allowing the four first cargo ropes 410 to jointly suspend the cargo, placing the cargo directly below the suspending device 100. Optionally, the end of the first cargo rope 410 can be detachably connected to the connecting hole 1137. Specifically, the end of the first cargo rope 410 can be connected to the connecting hole 1137 via a hook or spring buckle, facilitating loading and unloading. In other embodiments, the connecting hole 1137 for connecting the cargo ropes can also be provided on the fixed body 111.
[0065] In this application embodiment, the aircraft 200 can be an unmanned aircraft 200, such as a multi-rotor drone, a compound-wing drone, or an unmanned helicopter; the aircraft 200 can also be a manned aircraft 200. When multiple manned aircraft 200 use the sling device 100 of this application embodiment to transport goods, the pulling force of each manned aircraft 200 can be made basically uniform, avoiding the situation where the force of one manned aircraft 200 exceeds its own load capacity, and at the same time reducing the difficulty of coordination and control when multiple manned aircraft 200 are transporting together.
[0066] In this embodiment, the shape of the hanging body 110 of the hanging device 100 is not limited to the square shape in the above embodiments, but can also be other regular polygons, such as equilateral triangles, regular pentagons, regular hexagons, etc. Each side is provided with a corresponding load-bearing pulley 121, and each corner is provided with a corresponding corner pulley 122. The number of aircraft 200 is set so that the number of aircraft 200 matches the number of sides. For the case of an even number of sides greater than or equal to four, the number of aircraft 200 matches the number of sides. This can be either the number of aircraft 200 is the same as the number of sides, or the number of aircraft 200 is half the number of sides. The aircraft 200 are evenly arranged along the circumference of the hanging device 100. For example, when the suspension body 110 is roughly hexagonal, six aircraft can be used to connect the load-bearing pulleys 121 on the six sides of the suspension body 110 and the corner pulleys 122 at the six corners respectively; or three aircraft 200 can be used to connect the load-bearing pulleys 121 on the three sides of the suspension body 110 and the corner pulleys at the six corners at intervals.
[0067] In summary, the sling device 100 provided in this application includes a sling body 110, a pulley mounting component connected to the sling body 110, and at least two pulley assemblies 120 mounted on the pulley mounting component. Each pulley assembly 120 is used to connect two aircraft 200 via a sling 300, and the sling body 110 is used to connect cargo. When using the sling device 100 provided in this application, the sling 300 and two or more aircraft 200 can be used to connect the sling device 100. The sling 300 between two aircraft 200 can be connected to the pulley mounting part through the pulley assembly 120, and then connected to the sling body 110. Due to the characteristics of the pulley assembly 120, when the position of one aircraft 200 changes relative to other aircraft 200, the pulley assembly 120 can slide relative to the sling 300, so that the force points on the sling 300 can be adaptively adjusted, which alleviates the phenomenon of uneven force between aircraft 200 caused by uncoordinated movements of aircraft 200, that is, reduces the mutual influence between aircraft 200. The sling device 100 provided in this application embodiment can alleviate the mutual influence between multiple aircraft 200, making the force on the aircraft 200 more balanced, thereby reducing the difficulty of coordination and control when multiple aircraft 200 are transported together; at the same time, the sling device of this application solves the problem of limited cargo weight transported by a single aircraft.
[0068] The flight transport system provided in this application includes at least two aircraft 200, a sling 300, and the aforementioned sling device 100. The aircraft 200 are connected by the sling 300 to form a closed loop. The sling 300 between adjacent aircraft 200 engages with the pulley assembly 120 of the sling device 100. Because the sling 300 connects to the sling device 100 via the pulley assembly 120, it can mitigate the mutual influence between multiple aircraft 200, resulting in a more balanced force distribution on the aircraft 200 and reducing the difficulty of coordinated control during collaborative transport of multiple aircraft 200.
