DETAILED DESCRIPTION
[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part 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 drawings here 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 present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0041] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0042] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.
[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may 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 use a single aircraft to transport a single large weight cargo. If multiple aircraft are used to carry cargo together, the coordinated control between the aircraft is difficult. When an aircraft produces an uncoordinated action, such as lowering the flight altitude relative to other aircraft, the weight borne by other aircraft will increase significantly; for example, when the crew turns, the cargo will swing outward due to the centrifugal force, and the force on the aircraft close to the inside will increase. In addition, when the cargo swings due to external force, the uniformity of force between aircraft will also be seriously affected. Therefore, the control of multiple aircraft in the prior art to coordinate the transportation of cargo is difficult and has poor stability.
[0045] To this end, the embodiment of the present application provides a hanging device, which cooperates with the hanging ropes between the aircraft by setting at least two sets of pulley assemblies, so that the hanging device can adaptively adjust its position relative to the hanging ropes, thereby balancing the forces on each aircraft, reducing the mutual influence between the aircraft, reducing the control difficulty of multiple aircrafts coordinating to transport goods, and improving the stability of the flight transportation system. In addition, the embodiment of the present application also provides a flight transportation system, including the above-mentioned hanging device.
[0046] Figure 1 Schematic diagram of a flight transportation system in one embodiment of the present application. Figure 1 As shown, the flight transportation system provided by the embodiment of the present application includes at least two aircraft 200, a sling 300 and a sling device 100, and each aircraft 200 is connected by the sling 300 to form a closed loop. The sling device 100 includes a sling body 110, a pulley mounting member connected to the sling body 110, and at least two groups of pulley assemblies 120 mounted on the pulley mounting member. The pulley mounting member is used to install the pulley assembly, and each group of pulley assemblies 120 is used to connect two aircraft 200 through the sling 300. In other words, the sling 300 between two adjacent aircraft 200 cooperates with the pulley assembly 120 on the sling device 100. The sling body 110 of the sling device 100 is used to connect cargo, and the aircraft 200 can sling the cargo through the sling device 100 and transport it.
[0047] Optionally, the number of pulley assemblies 120 on the hanging device 100 matches the number of aircraft 200, and the hanging rope 300 between every two adjacent aircraft 200 is connected to the hanging device 100 via a pulley assembly 120. Figure 1In the embodiment shown, the flight transportation system includes a total of four aircraft 200, and a total of four pulley assemblies 120 are provided on the suspension device 100. In other embodiments, the number of pulley assemblies 120 and the number of aircraft 200 can be increased or decreased as needed; in an optional embodiment, the number of aircraft 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 aircraft 200 passes through more than two pulley assemblies 120. For example, Figure 1 In the embodiment, the number of the aircraft 200 can be two, which can be symmetrically distributed around the hanging device 100.
[0048] It can be understood that when an aircraft 200 in the flight transportation system has an uncoordinated flight action, such as a sudden rise or fall, the suspension rope 300 between it and the adjacent aircraft 200 will naturally slide 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 where the force of one of the aircraft 200 exceeds its own load. At the same time, the suspension device 100 provided by the embodiment of the present application can reduce the mutual influence between the various aircraft 200 in the flight transportation system, reduce the difficulty of coordinated control of the aircraft 200, and improve the stability of the flight transportation system.
[0049] Optionally, at least one aircraft 200 is provided with a traction sheave 210, and the aircraft 200 provided with the traction sheave 210 cooperates with the suspension rope 300 through the traction sheave 210. It should be understood that the portion of the suspension rope 300 connected to the aircraft 200 through the traction sheave 210 may not have a rope head, but is directly wound around the traction sheave 210, so 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 sheave 210 is subjected to uneven force, the traction sheave 210 will roll relative to the suspension rope 300, and adjusting the force point of the traction sheave 210 on the suspension rope 300 can further reduce the influence of the uncoordinated actions of the adjacent aircraft 200 on the aircraft 200.
[0050] Optionally, the sling rope 300 is one and has two ends, both ends of the sling rope 300 are connected to the same aircraft 200, and the remaining aircraft 200 are all provided with traction sheaves 210 and cooperate with the sling rope 300 through the traction sheaves 210. In other words, one end of the sling rope 300 is connected to the initial aircraft 200, and then alternately passes through the pulley assembly 120 and other aircraft 200 with traction sheaves 210 in the extension direction of the sling rope 300, and finally, the other end of the sling rope 300 returns to the initial aircraft 200 and is fixedly connected thereto. Figure 1 In the embodiment shown, the Figure 1The aircraft 200 on the upper middle side is fixedly connected to the two rope ends of the suspension rope 300 , and the other three aircraft 200 are connected to the suspension rope 300 via the traction pulley 210 .
[0051] Figure 2 FIG. 1 is a schematic diagram of a flight transportation system in another embodiment of the present application. Figure 2 As shown, the suspension rope 300 is a ring-shaped closed structure, and each aircraft 200 is provided with a traction pulley 210, and each aircraft 200 cooperates with the suspension rope 300 through the traction pulley 210. Figure 2 In the embodiment, each aircraft 200 can freely adjust the position of the suspension rope 300 so that the force applied to each aircraft 200 can be more balanced.
[0052] Figure 3 FIG. 2 is a schematic diagram of the cooperation between the traction sheave 210 and the suspension rope 300 in the embodiment of the present application. Figure 3 As shown, the traction sheave 210 includes a seat 211, a traction member 213 and a roller 212, the roller 212 is rotatably connected to the seat 211, the traction member 213 is rotatably connected to the seat 211, the traction member 213 is connected to the aircraft 200, and the roller 212 cooperates with the suspension rope 300. Figure 3 As shown, the outer peripheral surface of the roller 212 has a groove for the rope 300 to be embedded, so as to prevent the rope 300 from being separated from the outer periphery of the roller 212. The seat 211 is a U-shaped member, and a part of the roller 212 is embedded in the seat 211 and is rotatably connected to the seat 211. The traction member 213 includes a lifting ring 2131 and a rotation shaft 2132, wherein the lifting ring 2131 is arranged on the rotation shaft 2132, and the rotation shaft 2132 is rotatably connected to the seat 211. The lifting ring 2131 can be connected to the aircraft 200 through a rope or other connecting parts. By making the lifting ring 2131 rotatable relative to the seat 211, the roller 212 can be unaffected by the posture of the aircraft 200, and the roller 212 can remain tangent to the rope 300, thereby reducing the risk of the rope 300 being worn and falling off from the roller 212, and also making the roller 212 roll more smoothly.
[0053] It should be understood that in other optional embodiments, all aircraft 200 may not be provided with traction sheaves 210, so each aircraft 200 is connected to two adjacent aircraft 200 via two ropes.
[0054] Figure 4 This is a schematic diagram of a hanging device 100 in one embodiment of the present application (one of the connecting members 113 is omitted); Figure 5 This is a schematic diagram of the coordination between the hanging device 100 and the hanging rope 300 in one embodiment of the present application; Figure 6 for Figure 5Optionally, the hanging device 100 includes at least three pulley assemblies 120, and the at least three pulley assemblies 120 are arranged around the circumference of the hanging body 110. In this embodiment, the hanging device 100 includes four pulley assemblies 120 as an example. Figures 4 to 6 As shown, in this embodiment, each group of pulley assemblies 120 includes at least two load-bearing pulleys 121 and at least one angle pulley 122. The angle 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 function of the load-bearing pulley 121 is to receive the upward traction force from the suspension rope 300, so that the suspension body 110 can be suspended in the vertical direction. In this embodiment, each group of pulley assemblies 120 includes two load-bearing pulleys 121 and one angle pulley 122. Since the two load-bearing pulleys 121 are subjected to the upward traction force of two different aircrafts 200, the axes of the two load-bearing pulleys 121 in the same group of pulley assemblies 120 are at an angle to adapt to the traction direction of different aircrafts 200. The function of the corner pulley 122 is to guide the turning of the suspension rope 300 between the two load-bearing pulleys 121, so that the suspension rope 300 can remain tangent to or close to the tangent position with two different load-bearing pulleys 121, reduce the wear of the suspension rope 300, and improve the smoothness of the rolling of the load-bearing pulley 121 along the suspension rope 300. In other embodiments, the number of the load-bearing pulleys 121 and the corner pulley 122 in the pulley assembly 120 can be increased as needed, for example, two or more load-bearing pulleys 121 are arranged on both sides of the corner pulley 122, and the number of the corner pulley 122 can also be two or more.
[0055] Optionally, the hanging body 110 is generally a regular polygon, the corners of the regular polygon are chamfered, the number of pulley assemblies 120 matches the number of sides of the regular polygon, the corner pulleys 122 of the pulley assemblies 120 are respectively arranged at the corners of the hanging body 110, the load-bearing pulleys 121 of the pulley assemblies 120 are distributed along the sides of the hanging body 110, and the extension direction of the hanging rope 300 is changed after passing through the corner pulleys 122. Figure 4-Figure 6 In the embodiment, optionally, the hanging body 110 is substantially square, the pulley assembly 120 is four groups, the corner pulleys 122 of the four pulley assemblies 120 are respectively arranged at the four corners of the hanging body 110, the load-bearing pulleys 121 of the four pulley assemblies 120 are distributed along the four sides of the hanging body 110, and the extension direction of the hanging rope 300 changes by 90° after passing through the corner pulleys 122. Optionally, the load-bearing pulleys 121 are arranged close to the corners, so that each group of pulley assemblies 120 is concentratedly arranged at the four corners, but the present application is not limited thereto, and it is also possible that the load-bearing pulleys 121 of the four pulley assemblies 120 are distributed along the four sides of the square, and it is also possible not to be close to the corners, as long as the force balance can be achieved.
[0056] In this embodiment, the hanging body 110 includes a fixed body 111, the pulley mounting member includes 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 mounted thereon, the height of the aircraft 200 relative to the hanging device 100 can be changed, which will 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 the top of 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 increase, and when the aircraft 200 moves away from the top of 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 decrease. In the present embodiment, the first pulley mounting member 131 is rotatable relative to the fixed body 111, so that the first pulley mounting member 131 and the load-bearing pulley 121 can adaptively adjust their postures according to the current inclination angle of the suspension rope 300, thereby keeping the load-bearing pulley 121 tangent or nearly tangent to the suspension rope 300, thereby ensuring the smoothness of the rolling of the load-bearing pulley 121.
[0057] Optionally, the number of the first pulley mounting members 131 is consistent with the number of the pulley assemblies 120, and each first pulley mounting member 131 is provided with two load-bearing pulleys 121, and the two load-bearing pulleys 121 belong to two adjacent groups of pulley assemblies 120. Optionally, the axes of the two load-bearing pulleys 121 on the same first pulley mounting member 131 are parallel. In this embodiment, the fixed body 111 is roughly square, and the number of the first pulley mounting members 131 is four, which are respectively provided on the four sides of the fixed body 111.
[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, and when the suspension rope 300 deviates from the tangent, the suspension rope 300 is prone to wear or even stuck. In this embodiment, when the suspension rope 300 passes through the pulley assembly 120, it passes through a 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, so that the suspension rope 300 can extend along the common tangent when passing through the load-bearing pulley 121 and the corner pulley 122, so that the corner pulley 122 and the load-bearing pulley 121 can rotate smoothly. Furthermore, the common tangent coincides with the axis of rotation of the first pulley mounting member 131, so that no matter how the first pulley mounting member 131 rotates, the angle pulley 122 and the load-bearing pulley 121 of the same pulley assembly 120 always have a common tangent, and the position of the common tangent remains unchanged, so that the suspension rope 300 will never deviate from the common tangent, and it is not easy to cause wear and jamming of the suspension rope 300.
[0059] In this embodiment, the pulley mounting member further includes a second pulley mounting member 132, the second pulley mounting member 132 is fixedly connected to the fixed body 111, and the corner pulley 122 is connected to the second pulley mounting member 132. Specifically in this embodiment, four second pulley mounting members 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 member 132 is arranged in a horizontal direction, the axis of the corner pulley 122 is perpendicular to the second pulley mounting member 132, and the axes of the corner pulleys 122 are parallel to each other.
[0060] Figure 7 This is a schematic diagram of a connecting member 113 in one embodiment of the present application; Figure 8 for Figure 4 The enlarged view of the part VIII in the figure. Figures 4 to 8 In this embodiment, a connecting member 113 is provided on the fixed body 111, and the first pulley mounting member 131 is rotatably connected to the connecting member 113. The connecting member 113 is provided with a first abutting surface 1134 and a second abutting surface 1135 at an angle, and the first abutting surface 1134 and the second abutting surface 1135 are respectively used to abut the first pulley mounting member 131 when the first pulley mounting member 131 rotates to two extreme positions. By providing the first abutting surface 1134 and the second abutting surface 1135 on the connecting member 113, the rotation angle travel of the first pulley mounting member 131 can be effectively limited.
[0061] Optionally, the connecting member 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 so that the connecting member 113 is U-shaped, the first connecting portion 1131 is connected to the fixed body 111, the two second connecting portions 1132 are connected to the first pulley mounting member 131, and each second connecting portion 1132 has a first abutting surface 1134 and a second abutting surface 1135. Figure 7 As shown, the connecting member 113 is an integrally formed plate body, which is bent to form a first connecting portion 1131 and two second connecting portions 1132; a first abutting surface 1134 and a second abutting surface 1135 are formed on the side of the second connecting portion 1132. It can be understood that the angle ( Figure 7 The larger the angle (shown in the middle angle A), the smaller the rotation angle range of the first pulley mounting member 131, which means the smaller the rotation adjustment range of the first pulley mounting member 131; the smaller the angle between the first abutting surface 1134 and the second abutting surface 1135, the larger the rotation angle range of the first pulley mounting member 131. However, if the angle between the first abutting surface 1134 and the second abutting surface 1135 is too small, it will affect the structural strength of the connecting member 113. Therefore, considering the adjustment range and the structural strength of the connecting member 113, optionally, the angle between the first abutting surface 1134 and the second abutting surface 1135 can be in the range of 60° to 120°. Specifically, assuming that the hanging device 100 is placed horizontally and the first pulley mounting member 131 is rotated to the vertical direction, the rotation angle of the first pulley mounting member 131 is 0°, then when the angle between the first abutting surface 1134 and the second abutting 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 abutting surface 1134 and the second abutting 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 abutting surface 1134 and the second abutting surface 1135 is 120°, the rotation angle range of the first pulley mounting member 131 is -30° to 30°. Preferably, the angle between the first abutting surface 1134 and the second abutting surface 1135 is 90°, and the rotation angle range of the first pulley mounting member 131 is -45° to 45°.
[0062] Fig. 9 and Fig.10 This is a schematic diagram of the first pulley mounting member 131 rotating to two extreme positions in one embodiment of the present application. Fig. 9 In the embodiment, the first pulley mounting member 131 is in the extreme position of being extended outwards. Fig.10 In the figure, the first pulley mounting member 131 is in the extreme position of being retracted inwards, and the position of the first pulley mounting member 131 reflects the position change of the aircraft 200 relative to the fixed body 111. Assuming that at the same height, Fig. 9 The position of the first pulley mounting member 131 reflects that the aircraft 200 is farther away from the hanging device 100 in the horizontal direction; Fig.10 The position of the first pulley mounting member 131 reflects that the aircraft 200 is relatively close to the hanging device 100 in the horizontal direction. Since different aircraft 200 may have different positions relative to the hanging device 100, the first pulley mounting members 131 may also maintain different postures. In addition, the height change of the aircraft 200 and the shaking of the cargo will also affect the angle between the first pulley mounting member 131 and the fixed body 111.
[0063] Please continue to refer to Figure 7 and Figure 8 In this embodiment, two shaft bodies 1311 are arranged at intervals on each first pulley mounting member 131, and an axial hole 1133 is respectively arranged on the two second connecting parts 1132 of the connecting member 113, and the two shaft bodies 1311 are pivotally connected to the corresponding second connecting parts 1132 through the two axial holes 1133. The first connecting part 1131 is provided with a mounting hole 1136, so the connecting member 113 can be fixedly connected to the fixed body 111 through a bolt and the mounting hole 1136. In other embodiments, the connecting member 113 can also be welded or integrally formed with the fixed body 111.
[0064] Furthermore, a connection hole 1137 is provided on the connecting member 113, and the connection hole 1137 is used to connect with a cargo rope for connecting cargo. In this embodiment, the connecting member 113 not only connects the first pulley mounting member 131, but also plays the role of hanging cargo, and the cargo can be hung below the hanging device 100 through the cargo rope. Fig.11 FIG. 1 is a schematic diagram of a hanging device 100 connected to a cargo rope in one embodiment of the present application. Fig.11 As shown, specifically, a first cargo rope 410 can be connected to each of the multiple connectors 113, and the ends of the four first cargo ropes 410 are connected to a second cargo rope 420 after merging, and the second cargo rope 420 is connected to the cargo, so that the four first cargo ropes 410 can hang the cargo together, so that the cargo is directly below the hanging device 100. Optionally, the end of the first cargo rope 410 can be detachably connected to the connection hole 1137, and specifically, the end of the first cargo rope 410 can be connected to the connection hole 1137 by a hook or a spring buckle, so as to facilitate loading and unloading. In other embodiments, the connection hole 1137 for connecting the cargo rope can also be set on the fixed body 111.
[0065] In the embodiment of the present application, the aircraft 200 can be an unmanned aerial vehicle 200, such as a multi-rotor drone, a composite wing drone or an unmanned helicopter; the aircraft 200 can also be a manned aerial vehicle 200. When multiple manned aerial vehicles 200 use the hanging device 100 of the embodiment of the present application to transport goods, it can also be achieved that the pulling force of each manned aerial vehicle 200 is basically uniform, avoiding the situation where the force of one of the manned aerial vehicles 200 exceeds its own load capacity, and at the same time can reduce the difficulty of coordinated control during the coordinated transportation of multiple manned aerial vehicles 200.
[0066] The shape of the hanging body 110 of the hanging device 100 in the embodiment of the present application is not limited to the square in the above embodiment, and can also be other regular polygons, such as regular triangles, regular pentagons, regular hexagons and other shapes. A corresponding load-bearing pulley 121 is set on each side, and a corresponding corner pulley 122 is set on each corner. The number of aircraft 200 is set accordingly so that the number of aircraft 200 matches the number of sides. For the case of an even number of sides with a number of sides greater than or equal to four, the number of aircraft 200 matches the number of sides, which can be the same as the number of sides, or the number of aircraft 200 is half the number of sides, and the aircraft 200 can be evenly arranged along the circumference of the hanging device 100. For example, when the hanging body 110 is roughly in the shape of a regular hexagon, six aircrafts can be used to respectively connect the load-bearing pulleys 121 on the six sides of the hanging body 110 and the corner pulleys 122 at the six corners; or three aircrafts 200 can be used to connect the load-bearing pulleys 121 on the three sides of the hanging body 110 and the corner pulleys 122 at the six corners at intervals.
[0067] In summary, the hanging device 100 provided in the present application includes a hanging body 110, a pulley mounting member connected to the hanging body 110, and at least two pulley assemblies 120 installed on the pulley mounting member, each set of pulley assemblies 120 is used to connect two aircraft 200 through a hanging rope 300, and the hanging body 110 is used to connect cargo. When using the suspension device 100 provided in the present application, the suspension device 100 can be connected by using a suspension rope 300 and more than two aircraft 200. The suspension rope 300 between the two aircraft 200 can be connected to the pulley mounting member through the pulley assembly 120, and then connected to the suspension body 110. Due to the characteristics of the pulley assembly 120, when the position of one aircraft 200 relative to other aircraft 200 changes, the pulley assembly 120 can slide relative to the suspension rope 300, so that the force points on the suspension rope 300 can be adaptively adjusted, thereby alleviating the uneven force phenomenon between the aircraft 200 caused by the uncoordinated movements of the aircraft 200, that is, reducing the mutual influence between the aircraft 200. The hanging device 100 provided in the embodiment of the present application can alleviate the mutual influence between multiple aircraft 200, so that the force applied to the aircraft 200 is more balanced, thereby reducing the difficulty of coordinated control during the collaborative transportation of multiple aircraft 200; at the same time, the use of the hanging device of the present application solves the problem of limited cargo weight transported by a single aircraft.
[0068] The flying transportation system provided by the embodiment of the present application includes at least two aircraft 200, a sling 300 and the above-mentioned hanging device 100, each aircraft 200 is connected by the sling 300 to form a closed loop, and the sling 300 between two adjacent aircraft 200 cooperates with the pulley assembly 120 of the hanging device 100. Since the sling 300 is connected to the hanging device 100 through the pulley assembly 120, the mutual influence between the multiple aircraft 200 can be alleviated, so that the force of the aircraft 200 is more balanced, thereby reducing the coordination and control difficulty of the coordinated transportation of multiple aircraft 200.
