Description

Technical Field

[0001] This invention relates to a device for quickly securing a large unmanned helicopter into a vehicle-mounted container, and particularly to a device for securing two large unmanned helicopters arranged in parallel with their tails interlaced inside a vehicle-mounted container, belonging to the field of vehicle-mounted container technology. Background Technology

[0002] Large unmanned helicopters are equipped with a main rotor on top and a tail rotor at the rear. They have a long fuselage and a shape very similar to manned helicopters, featuring large payload capacity and long mission duration. Currently, large unmanned helicopters are increasingly widely used, such as for establishing aerial communication nodes and aerial relay stations, or for performing long-range air transport, long-range air support, and long-range air strike missions. The payload varies depending on the mission. To meet the need for rapid relocation of large unmanned helicopters, a device is required that can transport two large unmanned helicopters (with their main rotors removed) tail-to-tail into a vehicle-mounted container and quickly secure them inside. After rapid relocation to the designated work area, the two large unmanned helicopters can then be quickly unloaded and put into operation. Summary of the Invention

[0003] The purpose of this invention is to provide a compact vehicle-mounted large unmanned helicopter quick-fixing device. Using this device, two large unmanned helicopters can be quickly fixed in the vehicle-mounted container, or two large unmanned helicopters can be quickly transferred from the vehicle-mounted container to the ground for use.

[0004] This invention is achieved through the following technical solution:

[0005] A rapid securing device for a vehicle-mounted large unmanned helicopter includes a limiting rope securing mechanism, a limiting pressure plate, a paired transfer trolley, a movable sliding plate, a clamping and locking mechanism, and two sets of staggered slide rail assemblies. The limiting rope securing mechanism is respectively located between the top wall of the cabin and the cabin floor. The sunken slide rail assemblies are embedded in the cabin floor of the vehicle-mounted container, including two sets of inner slide rails staggered on the cabin floor and two sets of outer slide rails staggered on the inner plate of an electrically folding hydraulic tailboard. The inner slide rail sets include two parallel inner slide rails, and the outer slide rail sets include two parallel outer slide rails. The inner plate is adjacent to the rear of the cabin floor. The inner and outer slide rails have the same structure and equal track gauge, and the track gauge of each set of inner and outer slide rails matches the landing skid spacing of the large unmanned helicopter. The adjacent ends of the inner and outer slide rails are connected. The movable sliding plate is embedded and supported in the outer slide rails. The landing skids of the large unmanned helicopter are supported on a movable sliding plate. The upturned ends of the sliding rods of the landing skids abut against the two ends of the movable sliding plate. The movable sliding plate carries the large unmanned helicopter along two outer rails and slides into the inner rail until it reaches one end of the inner rail. The end of the inner rail is close to the inner wall of the cabin adjacent to the front of the vehicle. A limiting plate is placed horizontally on the landing skids. The two ends of the limiting plate are pressed and locked to the landing skids of the large unmanned helicopter on the cabin floor by a pressing and locking mechanism, and locked by the pressing and locking mechanism, thereby fixing the two large unmanned helicopters arranged in parallel with their tails staggered in the vehicle-mounted cabin. One end of the transfer trolley is connected to the sliding rods on both sides of the landing skids of the large unmanned helicopter. At the same time, the transfer trolleys on both sides of the landing skids are pushed to push the unmanned helicopter from the ground onto the movable sliding plate on the upper side of the two outer rails of the inner plate of the unfolded and lowered electric folding hydraulic tail plate.

[0006] The technical solution of the present invention can also be further implemented through the following technical solutions:

[0007] Furthermore, the limiting pull rope fixing mechanism includes two sets of upper pull rings, two sets of lower pull rings, two sets of upper limit pull ropes, and two sets of lower limit pull ropes. Each set of upper pull rings includes four upper pull rings, and each set of lower pull rings includes four lower pull rings. The upper pull rings, arranged in a rectangle, are fixed to the front of one side and the rear of the other side of the cabin top wall, respectively, and correspond to the positions on both sides of the top rotor of the two large unmanned helicopters that are staggered end to end. Each set of upper limit pull ropes and each set of lower limit pull ropes includes two corresponding upper limit pull ropes and two lower limit pull ropes. The two upper limit pull ropes are tied at both ends to the upper pull rings at opposite corners of the cabin top wall, and the middle parts of the two upper limit pull ropes are crossed and tightly wound around the top rotor of the large unmanned helicopter. The two lower limit pull ropes are tied at both ends to the lower pull rings at opposite corners of the cabin floor, and the middle parts of the two lower limit pull ropes are crossed and pressed against the landing skids of the large unmanned helicopter.

[0008] Furthermore, the transfer trolley includes a frame, a push rod, an axle, and a hook assembly, as well as two inflatable rubber wheels arranged side by side. The frame is a rectangular frame structure welded from rectangular steel pipes. The axle passes through the middle of the frame and is perpendicularly fixed to the middle of the frame. Both ends of the axle are hinged to the inflatable rubber wheels. A side bar on one side of the frame extends outward, and one end of a cross pin is perpendicularly fixedly welded to the side bar on one side of the frame. One end of the push rod passes through the center of one end of the frame and is perpendicularly fixed to the cross bar in the middle of the frame. The upper end of the hook assembly is sleeved on the push rod. On the end facing the inflatable rubber wheel, the upper sides of the hook and ring assembly are limited by limiting sleeves; when transporting the large unmanned helicopter, the lower end of the hook and ring assembly hooks the middle of the corresponding sliding bar of the large unmanned helicopter's landing skid; the cross pin is hinged to the upper end of a pair of lower ear plates, and the lower ends of the pair of lower ear plates are fixed to the middle of the corresponding sliding bar of the large unmanned helicopter's landing skid, thereby connecting the transport trolley to both sides of the large unmanned helicopter's landing skid as a whole, and the two inflatable rubber wheels support the corresponding sliding bar.

[0009] Furthermore, the hook and ring assembly includes a collar and a hook at the lower end of the collar. The collar is sleeved on the end of the push rod facing the inflatable rubber wheel. The upper end of the hook is hinged to the lower side of the collar. The lower end of the hook hooks respectively hooks the middle of the sliding bar corresponding to the landing skid of the large unmanned helicopter.

[0010] Furthermore, the inner and outer slide rails, which have the same structure, include their respective corresponding grooved slide rail bodies, multiple horizontal guide wheel assemblies, and multiple vertical support wheel assemblies. The length of the grooved slide rail body of the outer slide rail is shorter than that of the inner slide rail body. The length of the grooved slide rail body of the outer slide rail matches the length of the inner plate of the electric folding hydraulic tail plate. Multiple spaced-apart relief holes are evenly distributed on the bottom of the groove of the grooved slide rail body. The bottom of the horizontal support of the multiple spaced-apart horizontal guide wheel assemblies is fixed on the inner side of the groove edge of the grooved slide rail body, and the wheel surfaces of the horizontal guide wheels are opposite each other. The two sides of the movable slide plate are adjacent to the corresponding horizontal guide wheels. The bottom of the vertical support wheel assemblies is fixed at intervals on both sides of the groove bottom of the grooved slide rail body. The flanges on both sides of the movable slide plate are supported on the vertical wheels of the vertical support wheel assemblies.

[0011] Furthermore, the movable slide plate includes a grooved slide plate, a rubber plate, two limiting pins, and two rubber wedge blocks. One end of each limiting pin is opposite to the grooved slide plate, and the other end is fixed to the center of the end of the movable slide plate. The rubber plate is embedded and fixed in the middle of the grooved slide plate, and the inclined surfaces of the rubber wedge blocks are fixed to the two ends of the grooved slide plate respectively. The sliding rod of the landing skid is supported on the rubber plate, and the upturned ends of the sliding rod of the landing skid abut against the inclined surfaces of the rubber wedge blocks, so that the landing skid is positioned on the movable slide plate. When the movable slide plate carries the large unmanned helicopter to the end of the inner slide rail, the limiting pin at the center of one end of the movable slide plate is embedded in the limiting hole at the corresponding end of the inner slide rail, so that the movable slide plate is axially limited in the cabin. When the movable slide plate carries the large unmanned helicopter from inside and outside the cabin to the inner plate of the electric folding hydraulic tail plate, the limiting pin at the center of the other end of the movable slide plate is embedded in the limiting seat on the outer plate of the electric folding hydraulic tail plate, so that the movable slide plate is axially limited on the electric folding hydraulic tail plate.

[0012] Furthermore, the limiting pressure plate is a groove-shaped welded part, with an upper plate and a lower plate welded to the upper and lower sides of both ends of the limiting pressure plate, respectively. The thickness of the ends of the limiting pressure plate is less than the thickness of the middle of the limiting pressure plate. The pressing and locking mechanism is fixed on the inner end of the upper plate, including a T-shaped lever, a limiting flange, a spring pin seat, and a spring pin. The limiting flange is fixed on the middle part of the stepped shaft of the T-shaped lever. When the limiting pressure plate presses against the lifting and lowering skid, the lower end screw of the stepped shaft passes vertically through the inner end of the upper plate, the lower plate, and the movable sliding plate in sequence and is screwed into the cabin floor of the vehicle-mounted container until the lower side of the limiting flange abuts against the inner end of the upper plate, and the lower plate presses against the sliding rod of the lifting and lowering skid.

[0013] Furthermore, the spring pin seats are respectively fixed to the inner end of the upper plate, and the middle part of the spring pin is horizontally fixed in the spring pin seat; when the limiting pressure plate presses the lifting and lowering skid, one end of the spring pin extends into the limiting notch evenly distributed around the circumference of the limiting flange to lock the T-shaped lever.

[0014] This invention employs a structure where a pair of transfer trolleys are fixed to the lower sides of the landing skids of a large unmanned helicopter, allowing two large unmanned helicopters, arranged end-to-end, to be pushed sequentially from the ground onto the movable sliding plate of the electric folding hydraulic tailgate's outer rail. They are then pushed into the outer rail inside the vehicle-mounted cabin. A limiting pressure plate locking mechanism secures the two large unmanned helicopters within the cabin, and a limiting rope fixing mechanism further secures them. This invention fixes two large unmanned helicopters, arranged end-to-end, in a standard 40-foot-long vehicle-mounted cabin, significantly improving the cabin's space utilization. Using this invention makes the relocation of large unmanned helicopters convenient and quick, greatly improving their mobility. It is easy to operate, reliable, durable, and inexpensive, and has wide applications in the field of large unmanned helicopter vehicle-mounted applications.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] In the description of this invention, terms such as “center,” “upper,” “lower,” “left,” “right,” “inner,” and “outer” that indicate orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and do not indicate or imply that the device referred to must have a specific orientation.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment includes a limiting pull rope fixing mechanism 1, a limiting pressure plate 2, and a pair of transfer trolleys 3, a moving slide plate 4, a pressing and locking mechanism 5, and two sets of slide rail assemblies 6 arranged in an alternating manner. The sunken slide rail assemblies 6 are respectively embedded and installed on the cabin floor 71 of the vehicle-mounted cabin 7, including two sets of inner slide rail assemblies 61 arranged in an alternating manner on the cabin floor 71, and two sets of outer slide rail assemblies 62 arranged in an alternating manner on the inner plate 81 of the electric folding hydraulic tail plate 8. The inner slide rail assembly 61 includes two parallel inner slide rails 611, and the outer slide rail assembly 62 includes two parallel outer slide rails 621. The inner panel 81 is adjacent to the rear of the cabin floor 71. The inner slide rail 611 and the outer slide rail 621 have the same structure and equal track gauge. The track gauge of each set of inner slide rail 611 and the track gauge of each set of outer slide rail 621 are respectively matched with the spacing of the landing skids 91 of the large unmanned helicopter 9. The adjacent ports of the inner slide rail 611 and the outer slide rail 621 are connected.

[0029] like Figure 6 As shown, the inner slide rail 611 and outer slide rail 621, which have the same structure, include their respective corresponding grooved slide rail bodies 6111, multiple horizontal guide wheel assemblies 6112, and multiple vertical support wheel assemblies 6113. The length of the grooved slide rail body 6111 of the outer slide rail 621 is shorter than that of the inner slide rail body 6111. The length of the grooved slide rail body 6111 of the outer slide rail 621 matches the length of the inner plate 81 of the electric folding hydraulic tail plate 8. Multiple spaced relief holes 613 are evenly distributed on the bottom of the groove of the grooved slide rail body 6111. The bottom of the horizontal supports 6113 of the multiple spaced horizontal guide wheel assemblies 6112 are respectively fixed on the inner side of the groove edge 6114 of the grooved slide rail body 6111, and the wheel surfaces of the horizontal guide wheels 6115 face each other. The two sides of the movable slide plate 4 are adjacent to the corresponding horizontal guide wheels 6115. The bottom of the vertical support wheel assembly 6113 is fixed at intervals on both sides of the groove bottom of the grooved slide rail body 6111, and the flanges 411 on both sides of the movable slide plate 4 are supported on the vertical wheels 6116 of the vertical support wheel assembly 6113. This structure not only significantly reduces the moving resistance of the movable slide plate 4 carrying the large unmanned helicopter 9 on the inner slide rail 611 and outer slide rail 621, but also provides precise guidance for the movement of the movable slide plate 4.

[0030] like Figure 6As shown, the movable slide plate 4 includes a grooved slide plate 41, a rubber plate 42, two limiting pins 43, and two rubber wedge blocks 44. One end of each limiting pin 43 is opposite to the grooved slide plate 41, and the other end of each limiting pin 43 is fixed to the center of the end of the movable slide plate 41. The rubber plate 42 is embedded and fixed in the middle of the grooved slide plate 41, and the inclined surfaces of the rubber wedge blocks 44 are fixed to the two ends of the grooved slide plate 41 respectively. The sliding rod 911 of the landing skid 91 of the large unmanned helicopter 9 is supported on the rubber plate 42, and the upturned ends of the sliding rod 911 of the landing skid 91 abut against the inclined surfaces of the rubber wedge blocks 44, so that the landing skid 91 is positioned on the movable slide plate 4. The friction between the rubber plate 42 and the rubber wedge blocks 44 and the sliding rod 911 of the landing skid 91 can prevent relative displacement between the large unmanned helicopter 9 and the movable slide plate 4 when it moves.

[0031] like Figure 1 and Figure 10 As shown, when the mobile slide plate 4, carrying the large unmanned helicopter 9, moves to the end of the inner slide rail 611, the limiting pin 43 at the center of one end of the mobile slide plate 4 is respectively inserted into the limiting hole 6117 at the corresponding end of the inner slide rail 61, so that the mobile slide plate 4 is axially limited in the cabin. Figure 1 , Figure 5 and Figure 10 As shown, when the mobile skateboard 4 carries the large unmanned helicopter 9 from inside and outside the cabin to the inner plate 81 of the electric folding hydraulic tail plate 8, the limiting pin 43 at the center of the other end of the mobile skateboard 4 is respectively embedded in the limiting seat 83 on the outer plate 82 of the electric folding hydraulic tail plate 8, so that the mobile skateboard 4 is axially limited on the electric folding hydraulic tail plate 8, which facilitates the removal of the large unmanned helicopter 9 after the electric folding hydraulic tail plate 8 descends and lands, thus preparing for the take-off of the large unmanned helicopter 9.

[0032] like Figure 1 , Figure 8 and Figure 9 As shown, the limiting pressure plate 2 is a groove-shaped welded part. An upper plate 21 and a lower plate 22 are welded to the upper and lower sides of both ends of the limiting pressure plate 2, respectively. The thickness of the ends of the limiting pressure plate 2 is less than the thickness of the middle part. The clamping and locking mechanism 5 is fixed to the inner end of the upper plate 21, including a T-shaped lever 51, a limiting flange 52, a spring pin seat 53, and a spring pin 54. The limiting flange 52 is fixed to the middle of the stepped shaft 511 of the T-shaped lever 51. When the limiting pressure plate 2 clamps the lifting skid 91, the lower end screw 512 of the stepped shaft 511 passes vertically through the inner end of the upper plate 21 and the lower plate 22, respectively, and is screwed into the cabin floor 71 of the vehicle-mounted container 7 until the lower side of the limiting flange 52 abuts against the inner end of the upper plate 21, and the lower plate 22 is clamped onto the sliding rod of the lifting skid 91. The lower screw 512 uses an M20×4 trapezoidal thread, which has the advantages of being wear-resistant, not easily stripped during frequent use, and requiring fewer rotations when unlocking and locking, making it convenient to use.

[0033] Spring pin seats 53 are fixed to the inner end of the upper plate 21, and spring pins 54 are horizontally fixed in the middle of the spring pin seats 53. When the limiting pressure plate 2 presses against the lifting skid 91, one end of the spring pin 54 extends into the circumferentially distributed limiting notches 521 of the limiting flange 52 to lock the T-shaped lever 51, thereby locking the large unmanned helicopter 9 to the cabin floor 71 and ensuring the transportation safety of the large unmanned helicopter 9.

[0034] like Figure 1 and Figure 2 As shown, the limiting pull rope fixing mechanism 1 includes 2 sets of upper pull rings 11, 2 sets of lower pull rings 12, 2 sets of upper limit pull ropes 13 and 2 sets of lower limit pull ropes 14. Each set of upper pull rings 11 includes 4 upper pull rings 11, and each set of lower pull rings 12 includes 4 lower pull rings 12. Each set of upper pull rings 12, arranged in a rectangle, is fixed to the front part of one side and the rear part of the other side of the top wall 72 of the cabin, and corresponds to the positions on both sides of the top rotor 72 of the two large unmanned helicopters 7 that are staggered end to end.

[0035] Each set of upper limit pull ropes 13 and each set of lower limit pull ropes 14 includes two upper limit pull ropes 13 and two lower limit pull ropes 14, respectively. The two upper limit pull ropes 13, which are arranged in a cross configuration, are tied at both ends to upper pull rings 11 at diagonal positions on the top wall of the cabin. The middle parts of the two upper limit pull ropes 11 are crossed and tightly wound around the top rotor frame 92 of the large unmanned helicopter 9. The two lower limit pull ropes 14, which are arranged in a cross configuration, are tied at both ends to lower pull rings 12 at diagonal positions connecting to the cabin floor 71. The middle parts of the two lower limit pull ropes 14 are crossed and pressed against the landing skid 71 of the large unmanned helicopter 7. This invention uses a limit pull rope fixing mechanism 1 to further secure the large unmanned helicopter, improving the reliability of off-road transportation of the large unmanned helicopter 9 carried by the vehicle-mounted container 7.

[0036] like Figure 3 and Figure 4As shown, the transfer trolley 3 includes a frame 31, a push rod 32, an axle 33, and a hook assembly 34, as well as two inflatable rubber wheels 35 arranged side by side. The frame 31 is a rectangular frame structure welded from rectangular steel pipes. The axle 33 passes through the middle of the frame 31 and is welded perpendicularly to the middle of the frame 31. Both ends of the axle 33 are hinged to the inflatable rubber wheels 34. The side rod 311 on the left side of the frame 31 extends outward. The left end of the cross pin 312 is perpendicularly fixedly welded to the side rod 311 on the left side of the frame 31. The right end of the push rod 32 passes through the center of the left end of the frame 31 and is perpendicularly fixedly connected to the middle cross bar 313 of the frame 31. The hook-and-loop assembly 34 includes a collar 341 and a hook 342 at the lower end of the collar 341. The collar 341 is fitted onto the end of the push rod 32 facing the inflatable rubber wheel 35. The collar 341 is limited on both sides by limiting sleeves 343. The upper end of the hook 342 is hinged to the lower side of the collar 341. When transporting the large unmanned helicopter 9, the lower end of the hook 342 hooks onto the middle of the corresponding sliding rod 911 of the landing skid 91 of the large unmanned helicopter 9. The cross pin 312 is hinged to the upper end of a pair of lower ear plates 314. The lower ends of the pair of lower ear plates 314 are fixed to the middle of the corresponding sliding rod 911 of the landing skid 91 of the large unmanned helicopter 9, thereby connecting the transport trolley 3 to both sides of the landing skid 91 of the large unmanned helicopter 9 as a whole. The two inflatable rubber wheels 35 support the corresponding sliding rod 911. This structure is equivalent to installing a pair of inflatable rubber wheels 35 on each side of the landing skid 91 of the large unmanned helicopter 9, making it easy to push the large unmanned helicopter 9 onto the outer plate 82 of the folding hydraulic tailgate 8 and store it inside the vehicle-mounted container 7. Alternatively, the large unmanned helicopter 9 can be pushed onto the ground from the outer plate 82, facilitating its rapid takeoff and mission execution.

[0037] The process of sequentially sending two large unmanned helicopters 9 into and locking them in the vehicle-mounted container 7, or sequentially sending them to the ground after unlocking them from the vehicle-mounted container 7, using this invention is as follows:

[0038] When it is necessary to transfer two large unmanned helicopters 9 sequentially from the ground into the cabin, first flip and unfold the electrically folding hydraulic tailgate 8 as follows: Figure 5 As shown, the outer panel 82 is lowered close to the ground. Then, the lower end of the hook 342 of the transfer trolley 3 hooks onto the middle of the corresponding sliding bar 911 of the landing skid 91 of the first large unmanned helicopter 9. The head of the large unmanned helicopter 9 faces the vehicle-mounted container 7. The cross pin 312 of the transfer trolley 3 is connected to the middle of the corresponding sliding bar 911 of the landing skid 91 through a pair of lower ear plates 314, so that the two sides of the landing skid 91 are lifted off the ground by the corresponding inflatable rubber wheels 35. After pressing down the push rod 32, the transfer trolley 3 is pushed to transport the large unmanned helicopter 9 to the inner panel 81 through the outer panel 82. The transfer trolley 3, which is fixed to the middle of the sliding bar 911, is then removed, so that the sliding bars 911 on both sides of the landing skid 91 fall onto the movable sliding plate 4 supported by the corresponding outer slide rail 621.

[0039] Next, the outer panel 81 and inner panel 82 of the electrically folding hydraulic tailgate 8 are moved horizontally upwards, so that the top surfaces of the outer slide rail 621 and the inner slide rail 611 on the cabin floor 71 are flush and the ends are aligned. The large unmanned helicopter 9 is then pushed along the outer slide rail 621 onto the inner slide rail 621 until it is as described above. Figure 10 The limiting pin 43 at the center of one end of the movable slide plate 4 is inserted into the limiting hole 6117 at the end of the corresponding inner slide rail 61, thereby axially limiting the movable slide plate 4 within the cabin. Then, the limiting pressure plate 2 presses down on the middle of the sliding rod 911 of the landing skid 91, and the T-shaped levers 51 on both ends of the limiting pressure plate 2 are rotated in the forward direction, so that the two ends of the limiting pressure plate 2 press against the corresponding sliding rod 911, and the T-shaped levers 51 are locked by releasing the spring pin 54. Finally, the large unmanned helicopter 9 is further locked by two upper limit pull ropes 13 and two lower limit pull ropes 14, thereby fixing the first large unmanned helicopter 9 inside the vehicle-mounted cabin 7.

[0040] The process of securing the second large unmanned helicopter 9 inside the vehicle-mounted container 7 is the same as the process of securing the first large unmanned helicopter 9 inside the vehicle-mounted container 7. The difference is that the tail of the second large unmanned helicopter 9 faces the vehicle-mounted container 7.

[0041] Through the above operations, two large unmanned helicopters, arranged in parallel with their tails staggered, were finally fixed inside the vehicle-mounted container 7.

[0042] The process of transferring two large unmanned helicopters 9 from the vehicle-mounted container 7 to the ground is the reverse of the aforementioned process and will not be repeated here.

[0043] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
