Description

Technical Field

[0001] This invention relates to the field of mechanical devices and transportation technology, and more specifically, to a modular self-moving device for aviation container pallets. Background Technology

[0002] Currently, the main containers used in air cargo transport are air-freight pallets. Air-freight pallets can stack and assemble bulk materials for transport as complete units, and can be used for material transfer via hoisting, forklifting, and sliding rail loading / unloading. However, using air-freight pallets for material transfer is highly dependent on transfer equipment (such as forklifts, cranes, and sliding rails), requiring significant pre-transfer preparation. In wartime, if cranes and forklifts are unavailable, air-freight pallets cannot be unloaded from the cargo hold and cannot function properly. Furthermore, air-freight pallets are generally only suitable for transport aircraft with sliding rails in the cargo hold; they cannot be used on Y-9 and civilian aircraft without side rails. Therefore, current air-freight pallet transport suffers from problems such as poor immediacy, mobility, and adaptability. Summary of the Invention

[0003] The purpose of this invention is to address the technical problems existing in the prior art by providing a modular self-moving device for air cargo pallets. This device is simple and reliable to install and disassemble, enabling short-distance transfer of air cargo pallets and improving the immediacy, mobility, and adaptability of air cargo pallet transportation.

[0004] To address the problems mentioned above, the technical solution adopted by this invention is as follows:

[0012] Furthermore, the flipping pressure plate includes a main body portion with a vertical axis and a bent portion, with the bent portion extending outward from the middle of the side of the main body portion; the flipping boss is provided with a mounting groove and is installed in conjunction with the bent portion of the flipped pressure plate, and the flipping boss and the bent portion are connected by a pin.

[0013] Furthermore, the fastening module employs a non-detachable fastener, comprising a connecting part and an operating part. The connecting part includes a threaded segment and a smooth shaft segment arranged sequentially along the axial direction, with the end of the smooth shaft segment connected to the operating part. The threaded segment of the connecting part is threadedly engaged with a flip boss, and the smooth shaft segment of the connecting part is connected and engaged with a flip pressure plate.

[0015] Furthermore, the traction module includes a wire rope, a closed turnbuckle, and a D-type shackle; one end of the wire rope is connected to the hanging ring, and the other end is connected to one end of the closed turnbuckle; the other end of the closed turnbuckle is connected to the D-type shackle.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) The present invention adopts a mobile base and a locking mechanism and is fastened through the gap of the serrated edge of the aviation container pallet. The connection operation is simple, conforms to ergonomics, and is easy to use. The quick-connect module, the traction module, and the walking module together drive the self-moving device and the aviation container pallet to move as a whole, realizing the short-distance transfer capability of the aviation container pallet, breaking the limitations of the use of the aviation container pallet, improving the mobility of operation deployment, and also improving the immediacy, mobility and adaptability of aviation container pallet transportation.

[0018] (2) In this invention, the movable base is composed of a first base plate and a first connecting block. The two can reliably connect through the limiting protrusion and the recess. The inclined surface on the limiting protrusion also cooperates with the serrated edge of the aviation container pallet to ensure the reliability of the positioning. The first connecting block is provided with a guide groove and is movably connected to the locking unit of the locking module. The pressure plate of the locking module clamps the serrated edge of the aviation container pallet. The structure and function are reliable, and the reliability of the connection is further guaranteed.

[0019] (3) In this invention, the locking unit adopts a first locking block and a second locking block arranged in opposite directions. The locking base plates of the two are stacked in the guide groove of the moving base. The locking base plates are respectively provided with mounting bosses and locking protrusions. The locking base plates of the two are moved by pressure head and spring. The locking protrusions are connected to the sawtooth inner cavity, which is reliable and easy to implement.

[0020] (4) In this invention, the movable base can also be a quarter-circular base, with flipping bosses formed on the outer edges of the mutually perpendicular side plates. The flipping bosses on both sides are movably connected to a set of locking modules. Each set of locking modules is movably connected to the flipping bosses through a flipping pressure plate and a pin. That is, by setting two sets of flipping pressure plates, the sawtooth frame at the diagonal position of the aviation container pallet can be matched and reliably connected. The structure is simple and easy to implement.

[0021] (5) In this invention, the flipping pressure plate adopts a main body and a bent part with a vertical axis. The bent part is hinged to the flipping boss. After the main body is flipped into place, it cooperates with the disc base to clamp the serrated edge of the aviation container pallet. The structure is simple and the connection is reliable. The fastening module adopts a non-detachable fastener and is equipped with a threaded section and a smooth shaft section. The inner diameter of the smooth shaft section is smaller than that of the threaded section. In this way, the non-detachable fastener will not come off the flipping pressure plate after it is screwed out of the threaded hole of the disc base. The connection and fixation can be achieved manually without the use of additional tools.

[0022] (6) In this invention, the quick-connect module drives the telescopic rod to press the compression spring through the operating rod, and after installation, the telescopic rod is locked in place with the inner cavity of the serrated frame of the aviation container pallet. The traction module is connected to the hanging ring of the quick-connect module through the wire rope, and a closed turnbuckle is set to adjust the length of the wire rope. The overall connection and installation are reliable, and the reliability of the traction and movement of the aviation container pallet is also guaranteed. Attached Figure Description

[0039] See Figure 1 As shown, the present invention provides a modular self-moving device for aviation container pallets, including a quick-connect module 11, a traction module 12, a mobile base 200, a walking module 100 disposed on the mobile base 200, and a locking mechanism 400. The locking mechanism 400 is movably disposed on the outer edge of the mobile base 200 and locks the aviation container pallet 1000 with the mobile base 200. The quick-connect module 11 is also connected to the aviation container pallet 1000. The traction module 12 is connected to the quick-connect module 11 and, together with the walking module 100, drives the self-moving device and the aviation container pallet 1000 to move as a whole.

[0040] The locking mechanism 400 includes a locking module and a fastening module. The locking module is movably disposed on the outer edge of the movable base 200 and cooperates with the aviation container pallet 1000. After the cooperation is in place, the fastening module locks the movable base 200 and the aviation container pallet 1000 together.

[0041] In one embodiment of the present invention, see further reading. Figure 2 and Figure 3 As shown, the movable base 200 includes a first substrate 201 and a first connecting block 202. The first connecting block 202 is disposed on the outer edge of the top surface of the first substrate 201, and a walking module 100 is disposed on the bottom surface of the first substrate 201. A limiting protrusion 24 extends axially from the outer edge of the first substrate 201, and a recess is formed on the mating surface of the first connecting block 202 and the first substrate 201. The recess is positioned and engaged with the limiting protrusion 24. The first connecting block 202 is connected and engaged with the locking mechanism 400.

[0042] Specifically, for ease of installation and space saving, the first base plate 201 adopts an isosceles trapezoidal structure. A caster mounting interface 21 is provided in the center of the bottom surface of the first base plate 201, and the walking module 100 is mounted thereon. Weight-reducing holes 22 are also provided on the first base plate 201 and on both sides of the walking module 100 to reduce the overall weight of the self-moving device. The number of the first connecting block 202 and the locking mechanism 400 can be selected according to actual needs.

[0043] Furthermore, the first connecting block 202 is provided with a guide groove 23 in the horizontal direction; the locking module includes a locking unit 4 and a pressure plate 3. The locking unit 4 is movably disposed within the guide groove 23, and the pressure plate 3 is disposed on the surface of the first connecting block 202 and connected to the locking unit 4 via a fastening module. The fastening module is detachably disposed on the pressure plate 3 and sequentially connects the first connecting block 202 and the locking unit 4.

[0044] Specifically, the first connecting block 202 is provided with a pressure plate interface 25 and a fastener 5 to connect the pressure plate 3 and the locking unit 4.

[0045] For further details, please refer to [link / reference]. Figure 4 and Figure 5 As shown, the locking unit 4 includes a first locking block 41, a second locking block 42, a pressure head 43, and a spring 44. Both the first locking block 41 and the second locking block 42 include a locking base plate 401. The side of the locking base plate 401 extends to form a mounting boss 402 and a locking protrusion 403. The locking base plates 401 of the first locking block 41 and the second locking block 42 are stacked in the guide groove 23. The mounting bosses 402 of the two blocks are respectively provided with the shaft portion of the pressure head 43. A spring 44 is provided on the shaft portion of the two pressure heads 43 and between the opposing mounting bosses 402. The heads of the two pressure heads 43 are pressing portions.

[0046] Furthermore, the locking protrusions 403 of the first locking block 41 and the second locking block 42 are arranged opposite to each other in the direction away from the axis. The locking protrusions 403 are inclined on the side of the locking base plate 401, that is, inclined from one end face to the other end face, which facilitates the connection with the serrated inner cavity of the aviation container pallet 1000 and improves the connection reliability between the locking mechanism 400 and the aviation container pallet 1000.

[0047] Specifically, the first locking block 41 and the second locking block 42 have a complementary structure, meaning their locking base plates 401 can be stacked and can move towards each other to engage with the guide groove 23 of the first connecting block 202. This allows the two locking blocks to enter the movable base 200 without interfering with each other, facilitating installation and ensuring reliability. The locking protrusions 403 of both the first locking block 41 and the second locking block 42 have the same shape as the serrated inner cavity of the aviation container pallet 1000, allowing for clearance fit. The inclined surface on the limiting protrusion 24 has the same inclination angle as the inclined surface of the serrated edge on the aviation container pallet 1000. That is, the serrated edge on the aviation container pallet 1000 is located on the inclined surface of the limiting protrusion 24 and is clamped by the pressure plate 3, ensuring uniform force on the pressure plate 3 and reliable connection.

[0048] Furthermore, the walking module 100 adopts omnidirectional casters with directional locks, which facilitates the movement of the self-moving device and thus facilitates the movement of the aviation container pallet 1000.

[0049] Specifically, the universal casters of the walking module 100 are installed under the panel of the external aviation container pallet 1000, so that the panel bears the force and the strength requirements of the self-moving device are reduced.

[0050] In this embodiment, the pressing part of the two pressing heads 43 is pressed, and the spring 44 is compressed by the action of the mounting boss 402, so that the locking base plates 401 of the first locking block 41 and the second locking block 42 move towards each other and overlap in the guide groove 23. The self-moving device is installed into the gap of the serrated edge of the aviation container pallet 1000. The pressing part of the two pressing heads 43 is released, and the locking base plates 401 of the first locking block 41 and the second locking block 42 move in opposite directions, so that the locking protrusions 403 of the first locking block 41 and the second locking block 42 cooperate with the inner cavity of the serrated edge of the aviation container pallet 1000. At this time, the pressure plate 3 and the inclined surface of the limiting protrusion 24 clamp the serrated edge. Then, the pressure plate 3 and the moving base 200 are fastened by the fastener 5, thus completing the positioning connection between the self-moving device and the aviation container pallet 1000.

[0051] In this embodiment, the number of first connecting blocks 202 and locking mechanisms 400 on the first base plate 201 can be set as needed. That is, two or more sets of first connecting blocks 202 and corresponding locking mechanisms 400 can be set. In each set of locking mechanisms 400, the pressure plate 3 of the locking unit 4 clamps the aviation container pallet, which can ensure the reliability of the connection between the self-moving device and the aviation container pallet. At the same time, the number of mobile bases 200 and walking modules 100 installed can be determined according to the actual load, thereby completing the installation of a specified number of modular self-moving devices.

[0052] In another embodiment of the present invention, see [reference needed]. Figure 6 As shown, the movable base 200 includes a quarter-circular base 6 and a flipping boss 61. A walking module 100 is provided on the end face of the disc base 6. The outer edges of the mutually perpendicular side plates of the disc base 6 extend to form flipping bosses 61. The flipping bosses 61 on both sides are movably connected to a set of locking modules. Each set of locking modules includes a flipping pressure plate 7 and a pin 8. The flipping pressure plate 7 is movably connected to the flipping boss 61 through the pin 8. After the flipping pressure plate 7 is flipped into place, it is fastened by a fastening module.

[0053] For further details, please refer to [link / reference]. Figure 6As shown, the flipping pressure plate 7 has an overall L-shaped structure, including a main body 701 with a vertical axis and a bent portion 702. The bent portion 702 extends outward from the middle of the side of the main body 701. The bent portion 702 is hinged to the flipping boss 61 of the disc base 6. The flipping boss 62 is provided with a mounting groove and is installed in conjunction with the bent portion 702 of the flipping pressure plate 7. The flipping boss 62 and the bent portion 702 are connected by a pin 8.

[0054] Specifically, the main body 701 is provided with a fastening threaded hole 72 for installing a non-detachable fastener 9. The bent part 702 is provided with a pin hole 71 for installing a pin 8 and hinged to the flipping boss 61 of the disc base 6. After the flipping pressure plate 7 is flipped into place, the flipping boss 62 is also provided with a threaded hole, and a fastening module is provided between it and the fastening threaded hole 72 on the main body 701. The flipping pressure plate 7 is located on the edge of the disc base 6.

[0055] In this embodiment, the disc base 6 is also provided with weight reduction holes to reduce weight. The position of the fastening interface on the disc base 6 matches the gap between the serrated edges of the four corners of the aviation container pallet 1000. After installation by the fastening module, the highest position is lower than the bearing surface of the aviation container pallet 1000.

[0056] For further details, please refer to [link / reference]. Figure 7 As shown, the fastening module uses a non-detachable fastener 9, including a connecting part 91 and an operating part 92. The connecting part 91 includes a threaded section and a smooth shaft section arranged sequentially along the axial direction. The end of the smooth shaft section is connected to the operating part 92. The threaded section of the connecting part 91 is threadedly engaged with the flip boss 62, and the smooth shaft section of the connecting part 91 is connected to the flip pressure plate 7. The inner diameter of the smooth shaft section is smaller than that of the threaded section. The operating part 92 includes two operating supports. One end of the two operating supports is connected to the connecting part 91 and forms a set included angle.

[0057] Specifically, the non-detachable fastener 9 engages with the flip panel 7 and the disc base 6 via the connecting part 91, facilitating the flipping movement and fixation of the flip panel 7. The operating part 92 drives the connecting part 91 to rotate, meaning the non-detachable fastener 9 itself is a manually tightenable structure, eliminating the need for additional tools such as wing bolts and improving the installation speed of the self-moving device. The inner diameter of the optical shaft section of the non-detachable fastener 9 is smaller than that of the threaded section, ensuring that the non-detachable fastener 9 will not detach from the flip pressure plate 7 after being unscrewed from the threaded hole of the disc base 6.

[0058] In this embodiment, the flipping pressure plate 7 is opened, and the fastening interfaces of the two flipping bosses 61 on the disc base 6 are placed in the gap of the serrated edge at the diagonal position of the aviation container pallet 1000. The flipping pressure plate 7 corresponding to the flipping bosses 61 is closed and fastened with a non-detachable fastener 9. That is, the connecting part 91 of the non-detachable fastener 9 passes through the fastening thread hole 72 and the fastening interface in sequence. That is, the flipping pressure plate 7 and the disc base 6 clamp the aviation container pallet 1000, thereby completing the connection between the two. The four corner positions of the aviation container pallet 1000 can be installed in sequence to ensure the reliability of the translation of the aviation container pallet 1000.

[0059] For further details, please refer to [link / reference]. Figure 9 and 10 As shown, the quick-connect module 11 includes a housing 115, a telescopic rod 112, a compression spring 114, an operating rod 113, and a hanging ring 111. The telescopic rod 112 is movably mounted on both opposite ends of the housing 115, and a compression spring 114 is positioned between the opposite ends of the telescopic rod 112. The surface of the housing 115 also has a sliding groove 116 and an operating rod 113, the end of which is connected to the telescopic rod 112. A hanging ring 111 for connecting the traction module 12 is welded to the surface of the housing 115.

[0060] Specifically, the outer shell 115 is a hollow cylinder with a circular guide groove in the hollow part, which facilitates the movement of the telescopic rod 112. The diameter of the telescopic rod 112 is smaller than the inner cavity size of the tray frame, which can play a fixing role. Two sliding grooves 116 are axially arranged on the circumferential surface of the outer shell 115, and operating rods 113 are respectively provided thereon.

[0061] For further details, please refer to [link / reference]. Figure 11 As shown, the traction module 12 includes a wire rope 121, a closed turnbuckle 122, and a D-type shackle 123; one end of the wire rope 121 is connected to the hanging ring 111, and the other end is connected to one end of the closed turnbuckle 122; the other end of the closed turnbuckle 122 is connected to the D-type shackle 123.

[0062] Specifically, each traction module 12 is connected to two quick-connect modules 11, i.e., D-type shackles 123 connect two sets of closed turnbuckles 122 and wire ropes 121. The closed turnbuckles 122 are used to adjust the length of the wire ropes 121 on both sides. The number of closed turnbuckles 122 and wire ropes 121 can also be adjusted according to actual needs.

[0063] In this embodiment, after the aviation container pallet 1000 is locked by the movable base 200 and the locking mechanism 400, when traction is required, the quick-connect module 11 is fixed to the edge of the aviation container pallet 1000. That is, the two operating levers 113 are moved in opposite directions, and the telescopic rod 112 is fully retracted into the outer shell 115. The outer shell 115 is placed into the corresponding serrated groove and the operating levers 113 are released, and the telescopic rod 112 extends into the serrated inner cavity for fixation. After connecting the quick-connect modules 11 on both sides, one end of the wire rope 121 is connected to the hanging ring 111. After the traction modules 12 on both sides are installed, the hook of the external drive device is connected to the D-type shackle 123 to complete the installation of the traction structure. Under the joint action of the walking module 100 and the traction module 12, the aviation container pallet 1000 is moved, realizing the immediacy, mobility and adaptability of aviation container pallet transportation.

[0064] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
