Description

Technical Field

[0001] This invention relates to the field of aviation ground support equipment, specifically to an all-attitude intelligent disassembly and assembly platform vehicle. Background Technology

[0002] Currently, in the assembly, maintenance and support of aero-engines, traditional engine installation equipment is mostly an integral structure. It is adjusted up and down through its core lifting mechanism (commonly a mechanical and electric lifting scissor lift structure). When connected to the engine, it can bear the entire weight of the engine. Therefore, traditional engine installation equipment requires a large volume and weight. However, due to the precision structure of aero-engines and the high installation accuracy requirements, the bulky traditional equipment cannot perform multi-attitude adjustments to the engine, making it difficult to meet the high efficiency and precision requirements of modern aviation maintenance and support. Summary of the Invention

[0003] The purpose of this invention is to provide an all-position intelligent disassembly and assembly platform vehicle that can perform multi-dimensional and posture adjustments on the engine, thereby improving the accuracy of engine adjustment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is a full-posture intelligent disassembly and assembly platform vehicle, including a vehicle body, a support area on the vehicle body, and a parking rack in the support area, which can support the engine. The vehicle body includes a bottom platform and an upper platform. The bottom platform is connected to a traveling mechanism. There are two upper platforms, which can be connected to a parking rack so that the parking rack is located between the two upper platforms. The bottom platform can enable the upper platforms to move longitudinally and can adjust the engine to a pitch position. The upper platform includes an adapter plate, a top tray, and a drive module, with the adapter plate connected to the lower platform; The top tray is located above the adapter plate; the drive module is mounted on the adapter plate and its output end is connected to the top tray, which can apply driving force to the top tray; the drive module can make the top tray move in multiple directions on the horizontal plane; after the bottom platform and the upper platform work together, the engine can be adjusted in six degrees of freedom.

[0005] The aforementioned bottom platform includes a chassis and a housing. There are two chassis, which are symmetrically arranged. Each chassis is connected to the upper platform on the corresponding side. The housing is located between the two chassis and is used to connect the two chassis. The chassis and the housing are slidably connected, allowing adjustment of the distance between the two chassis.

[0006] Furthermore, the chassis includes a bottom positioning plate and a lifting mechanism. The bottom positioning plate is connected to the traveling mechanism. The lifting mechanism is mounted on the bottom positioning plate and docks with the upper platform, enabling the upper platform to move longitudinally.

[0007] Furthermore, the lifting mechanism includes a herringbone lifting frame and a servo electric cylinder. There are two sets of herringbone lifting frames, both of which are connected to the bottom positioning plate. The servo electric cylinder is mounted on the bottom positioning plate and has two output ends, each of which is connected to the herringbone lifting frame on the corresponding side. When the servo electric cylinder is working, it can move the top tray longitudinally through the herringbone lifting frame.

[0008] Furthermore, the two output ends of the servo electric cylinder can work independently, enabling the corresponding A-frame lifting frame to operate. When the two A-frame lifting frames have a height difference, the top tray is tilted.

[0009] Furthermore, there are four drive modules arranged in a rectangular pattern. When the two drive modules located diagonally apply a driving force to the upper platform in the same direction, the upper platform is translated.

[0010] Furthermore, when the four drive modules work simultaneously and apply driving force to the four sides of the parking rack in sequence, the parking rack can be rotated.

[0011] Furthermore, the drive module includes a drive output component, a support plate, and a short lead screw. The drive output component is mounted on the bottom platform; the support plate is connected to the bottom platform and the upper platform; the short lead screw is connected to the drive output component, enabling the support plate to move.

[0012] Furthermore, the drive module also includes a transition plate, a cross roller bearing, a guide slider, and a guide rail. The transition plate is positioned above the support plate; the cross roller bearing is located between the transition plate and the support plate and is mated with both, allowing the transition plate to rotate relative to the support plate; the guide slider is mounted on the transition plate; the guide rail is mated with the upper platform and cooperates with the guide slider; the guide slider can move along the length of the guide rail.

[0013] Furthermore, the parking rack includes an external rack and an internal rack. The external rack can be connected to the upper platform; the internal rack is used to carry the engine and can be separated from the external rack.

[0014] Compared with the prior art, the beneficial effects of the present invention are that, through the composition structure of the upper platform and the cooperation of the lifting mechanism, the engine can be adjusted in height. At the same time, by controlling the lifting mechanism and the drive module, the engine can be adjusted in attitude such as pitch and rotation, enabling the engine to form a variety of attitudes, which greatly improves the controllability of the engine attitude.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] See Figures 1 to 2 As shown, an all-position intelligent disassembly and assembly platform vehicle includes a vehicle body, a walking mechanism installed on the vehicle body, and a support area provided on the vehicle body, which can place the engine in the support area and then connect the engine to the vehicle body. Alternatively, a parking rack can be provided in the support area, which is detachably connected to the vehicle body, and the engine can be placed on the parking rack, which can limit the engine.

[0019] In this technical solution, the vehicle body consists of a bottom platform 1 and an upper platform 2. The bottom platform 1 is connected to the traveling mechanism, and the upper platform 2 can be connected to the parking rack to enable the parking rack to move up and down, thereby changing the position of the engine.

[0020] There are two upper platforms 2, each slidably connected to the lower platform 1. The lower platform 1 consists of an adjusting slider, a housing 4, and two chassis 3, which are symmetrically arranged. The adjusting slider is mounted on the chassis 3, and a guide rail 5 is provided on the housing 4. The adjusting slider cooperates with the guide rail 5. A screw drive assembly is provided inside the housing 4, and the adjusting slider (not shown in the figure) is connected to the screw drive assembly. The screw drive assembly controls the adjusting slider to move along the guide rail 5, thereby moving the chassis 3 and increasing or decreasing the distance between the two chassis 3, thus adjusting the size of the support area. The traveling mechanism adopts a steering wheel form, which can rotate 90°. When it is necessary to reduce the distance between the two chassis 3, the steering wheel rotates 90 degrees, moving the steering wheel inward. When the two traveling chassis contact each other, the steering wheel stops moving. Depending on the engine specifications, the distance between the two chassis 3 can be adjusted, and the distance between the two upper platforms 2 is also adjusted. Then, the corresponding parking rack is installed on the vehicle body, forming a complete assembly. After the engine is supported and limited by the parking rack, the engine can be moved along with the vehicle body when it moves.

[0021] See Figures 3 to 5 As shown, the chassis 3 includes a bottom positioning plate 6 and a lifting mechanism. The lifting mechanism is mounted on the bottom positioning plate 6, and the output end of the lifting mechanism is connected to the upper platform 2, which can make the upper platform 2 move longitudinally through the lifting mechanism. In this technical solution, the upper platform 2 includes a transfer plate 8 and a top tray 9. The transfer plate 8 is connected to the lifting mechanism, and the top tray 9 is located above the transfer plate 8 and the two are movably connected. The top tray 9 is used to connect with the parking rack. The parking rack is located in the support area and can dock with the top tray 9 on the upper platform 2. Therefore, when it is necessary to disassemble the aircraft engine, the position of the vehicle body is first adjusted so that the parking rack is located in the support area. Then, the parking rack is connected to the top tray 9 on the upper platform 2. Then, by continuing to move the vehicle body, the parking rack is moved to directly below the aircraft engine. Then, through the operation of the lifting mechanism, the parking rack is gradually moved closer to the aircraft engine until the parking rack and the aircraft engine cooperate to form a support. After the aircraft engine is supported by the parking rack, the engine can be removed from the aircraft, and the separation of the engine from the aircraft can be achieved.

[0022] There are two operating methods for separating the aircraft from the engine; The first operating method: After the aircraft engine is connected to the parking rack, the lifting mechanism is used to move the top tray 9 downwards. At this time, the engine moves downwards accordingly. When the engine is moved to the lower position, the engine will not come into contact with the aircraft when the vehicle body is moved in any direction. At this time, the engine can be moved away by moving the vehicle body.

[0023] The second operating method: After the aircraft engine is connected to the parking rack, the vehicle body is moved directly. However, it should be noted that the vehicle body must be moved in the specified direction. During the movement, the engine should be kept away from the aircraft. After the engine is completely separated from the aircraft, the parking rack and engine are moved downward by controlling the lifting mechanism.

[0024] In both of the above operating methods, after the parking rack contacts the ground, the top tray 9 is moved downwards to separate it from the parking rack. The parking rack is equipped with casters. When the parking rack carrying the engine is on the ground, it can be pulled or pushed to transfer the engine.

[0025] In this example, see Figure 3 and Figure 4As shown, the lifting mechanism includes a herringbone lifting frame 7 and a servo electric cylinder 15. The servo electric cylinder 15 has two output ends and is mounted on the bottom positioning plate 6. There are two sets of herringbone lifting frames 7. The servo electric cylinder 15 is located between the two sets of herringbone lifting frames 7, and both sets of herringbone lifting frames 7 are connected to the servo electric cylinder 15. The servo electric cylinder 15 can control the operation of the two sets of herringbone lifting frames 7. The servo electric cylinder 15 and the herringbone lifting frames 7 are both located below the adapter plate 8. The top output ends of the two sets of herringbone lifting frames 7 are slidably connected to the adapter plate 8. The adapter plate 8 is movably connected to the top tray 9. When the adapter plate 8 moves vertically, it can drive the top tray 9 to move vertically, thereby adjusting the horizontal height of the top tray 9.

[0026] The A-frame lifting frame 7 includes a short connecting frame and a long connecting frame. The lower end of the short connecting frame is hinged to the bottom positioning plate 6, the upper end of the short connecting frame is hinged to the long connecting frame, and the upper end of the long connecting frame is hinged to the adapter plate 8. The lower end of the long connecting frame is slidably connected to the bottom positioning plate 6. At the same time, the lower end of the long connecting frame is also connected to the output end of the servo electric cylinder 15. When the servo electric cylinder 15 starts to work, its output end will move horizontally, which can make the long connecting frame flip and the short connecting frame flip around the lower end, thereby changing the horizontal height of the upper end of the long connecting frame, and thus adjusting the horizontal height of the adapter plate 8 to realize the lifting and lowering of the top tray 9.

[0027] The short connecting frame includes two short connecting rods 10, which are parallel to each other. The lower end of each short connecting rod 10 is hinged to the bottom positioning plate 6, and the upper ends of the two short connecting rods 10 are connected to the long connecting frame through the horizontal shaft 11. The long connecting frame includes a sliding plate 12 and two long connecting rods 13. The lower end of each long connecting rod 13 is connected to the bottom positioning plate 6 via a rail. The sliding plate 12 is hinged to the upper end of the two long connecting rods 13. The sliding plate 12 is slidably connected to the lower surface of the adapter plate 8. A bottom push shaft 14 is connected between the lower ends of the two long connecting rods 13. The bottom push shaft 14 is hinged to the output end of the servo electric cylinder 15. When the long connecting frame is flipped, the sliding plate 12 and the adapter plate 8 can move relative to each other on the horizontal plane. Once the A-frame lifting frames 7 on each chassis 3 are operational, the parking rack can begin to move vertically, thereby adjusting the position of the engine.

[0028] In this technical solution, see reference Figure 5 As shown, a drive module is installed on the upper platform 2. The drive module is located between the adapter plate 8 and the top tray 9 and can control the movement of the top tray 9 through the drive module.

[0029] See Figures 7 to 8As shown, there are four drive modules. Two drive modules are located on the front side of the adapter plate 8, namely the front first drive module 16 and the front second drive module 17. The other two drive modules are located on the rear side of the adapter plate 8, namely the rear first drive module 18 and the rear second drive module 19. The four drive modules are arranged in a rectangular configuration. The front first drive module 16 and the rear second drive module 19 are located at opposite corners of the rectangle, and a line connecting them forms the diagonal of the rectangle. The front second drive module 17 and the rear first drive module 18 are located at the other two opposite corners of the rectangle, and a line connecting them also forms the diagonal of the rectangle. The front first drive module 16 and the rear first drive module 18 form a first drive group, which is installed on the adapter plate 8 of one of the upper platforms 2. The front second drive module 17 and the rear second drive module 19 form a second drive group, which is installed on the adapter plate 8 of the other upper platform 2.

[0030] The top tray 9 can be moved in the X or Y direction by the operation of the drive module. Since the top tray 9 is connected to the parking rack, the position of the parking rack can be finely adjusted.

[0031] Specifically, the front first drive module 16 and the rear second drive module 19, which are located diagonally, can apply force to the upper platform 2 in the same direction (X direction). Both the front second drive module 17 and the rear first drive module 18 are provided with X-direction guide sliders 20, and X-direction guide rails are connected through the X-direction guide sliders 20. The X-direction guide rails extend along the X direction and are connected to the lower surface of the top tray 9. After the top tray 9 is subjected to a force along the X direction, the top tray 9 can move in the X direction.

[0032] Y-direction guide sliders 21 are provided on both the front first drive module 16 and the rear second drive module 19. The Y-direction guide sliders 21 are connected to Y-direction guide rails, which extend along the Y direction and are also connected to the top tray 9. The front second drive module 17 and the rear first drive module 18 can apply force to the top tray 9 along the Y direction. After the top tray 9 is connected to the parking rack, the position of the parking rack can be adjusted. By controlling the above four drive modules, it can also be used to rotate the parking rack, with a rotation angle between +5° and -5°.

[0033] When the vehicle body needs to rotate counterclockwise, the four drive modules are activated. At this time, the force output directions of the front first drive module 16 and the rear second drive module 19 are opposite. Specifically, the front first drive module 16 moves one of the top trays 9 forward, while the rear second drive module 19 moves the other top tray 9 backward. Similarly, the force output directions of the front second drive module 17 and the rear first drive module 18 are also opposite. Specifically, the front second drive module 17 and the rear first drive module 18 move the two top trays 9 away from each other, ultimately achieving the counterclockwise rotation of the parking rack.

[0034] When the vehicle body needs to rotate clockwise, all four drive modules are activated. At this time, the force output directions of the front first drive module 16 and the rear second drive module 19 are opposite. For example, the front first drive module 16 moves one of the upper platforms 2 to the rear, while the rear second drive module 19 moves the other upper platform 2 forward. After the front second drive module 17 and the rear first drive module 18 output their forces, they move the two upper platforms 2 toward each other, thus achieving the clockwise rotation of the parking frame.

[0035] In this technical solution, see reference Figure 6 As shown, the drive module includes a lower guide rail 22 and a motor 23. The output end of the motor 23 is connected to a reducer 24. The motor 23 and the reducer 24 form a drive output assembly. The lower guide rail 22 is mounted on the chassis 3. A support plate 25 is connected to the lower guide rail 22. A traction seat 26 is connected to the support plate 25. The traction seat 26 is connected to the output end of the reducer 24 through a short lead screw 27. When the motor 23 starts working, it can move the support plate 25 along the length of the lower guide rail 22. In this example, a transition plate 28 is provided above the support plate 25. The transition plate 28 is connected to the support plate 25 through a cross roller bearing 29, allowing the transition plate 28 to rotate relative to the support plate 25. The transition plate 28 is connected to the guide slider, which cooperates with the corresponding guide rail. It should be noted that the length extension direction of the guide rail is perpendicular to the length direction of the lead screw. Both the guide rail and the short lead screw 27 extend on the horizontal plane. Two support positioning seats are installed on the chassis 3. The traction seat 26 is located between the two support positioning seats. The short lead screw 27 passes through both the traction seat 26 and the two support positioning seats.

[0036] This technical solution enables the parking rack to perform lifting, pitching, horizontal rotation, and rolling (with one side of the top tray 9 being higher than the other side of the top tray 9), allowing the parking rack to adopt various postures, thereby facilitating the installation and removal of aircraft engines.

[0037] See Figure 9As shown, in this technical solution, the parking rack and the top tray 9 are detachably connected. For example, a lateral flat slot is provided on the parking rack, and a laterally protruding support is provided on the top tray 9. The support can enter the lateral flat slot. Specifically, the distance between the two chassis 3 needs to be adjusted first, and then the bottom platform 1 is moved toward the parking rack. When the parking rack is in the support area, the two chassis 3 are brought closer to each other. This process can drive the two upper platforms 2 to approach the parking rack, and finally the end of the support on the top tray 9 is located in the lateral flat slot.

[0038] Specifically, the parking rack includes an outer frame, which consists of a bottom frame and limiting arms 31. The bottom frame is a U-shaped frame, and there are four limiting arms 31 symmetrically arranged on the bottom frame. The bottom frame includes two long crossbeams 32 and two short longitudinal beams 33. The two long crossbeams 32 are arranged parallel to each other, and the two short longitudinal beams 33 are located between the two long crossbeams 32. The end of each short longitudinal beam 33 is connected to the corresponding side of the long crossbeam 32. Lateral flat slots are provided on the long crossbeams 32, and longitudinal pin holes are provided on the long crossbeams 32. After the tray on the top tray 9 is inserted into the lateral flat slot, the pin can be inserted into the pin hole, thereby connecting the two top trays 9 through the parking rack. This not only gives the parking rack a certain degree of connection firmness, but also helps to realize the horizontal rotation of the parking rack.

[0039] See Figures 10 to 11 As shown, as an improved embodiment of this technical solution, the above-mentioned parking rack also includes an internal rack, which is detachably connected to the external rack. The internal rack can move vertically and can support the engine. When the engine is disassembled, the internal rack can be moved vertically to achieve vertical movement of the engine. Specifically, as shown in the figure, the built-in frame includes a support plate 30, the bottom of which has casters, and a displacement slider 34 is fixed to the side of the support plate 30. A longitudinal groove is provided on the limiting arm 31 of the external frame, and the displacement slider 34 can be adapted to the longitudinal groove and then move within the longitudinal groove. An adapter seat 35 is provided on the limiting arm 31, which can dock with the displacement slider 34. At the same time, a long strip-shaped opening 36 extending along its length direction is provided on the limiting arm 31, and the adapter seat 35 is located in the long strip-shaped opening 36 and can slide along the length direction of the long strip-shaped opening 36. The adapter 35 is provided with a horizontal through hole, and the displacement slider 34 is provided with a threaded hole. When the threaded hole is aligned with the through hole, the displacement slider 34 can be connected to the adapter 35 by a long screw. A translation arm 37 is provided above the two long crossbeams 32. The two ends of the translation arm 37 are connected to the corresponding adapter seats 35. A guide sleeve 38 is provided in the middle of the translation arm 37. The guide sleeve 38 vertically passes through the translation arm 37. A lead screw nut is provided on the inner wall of the guide sleeve 38. A lead screw body 39 passes through the guide sleeve 38. The lead screw body 39 cooperates with the lead screw nut. When the lead screw body 39 rotates, it can perform longitudinal relative movement with the guide sleeve 38. In order to enable the lead screw body 39 to rotate, a horizontal positioning seat 40 is provided on the long cross beam 32 of the outer frame. The lower end of the lead screw body 39 passes through the horizontal positioning seat 40. The horizontal positioning seat 40 is connected to the long cross beam 32 through the vertical arm. At the same time, a drive unit is provided on the long cross beam 32. The output end of the drive unit is connected to the lower end of the lead screw body 39 through a gear set. When the drive unit is working, it can make the lead screw body 39 rotate. The drive unit includes a reducer and a drive motor 23. The output end of the reducer is connected to a gear set. When the drive motor 23 starts working, it can make the lead screw 39 rotate slowly.

[0040] To enable the internal frame to be separated from the external frame, the short longitudinal beams 33 on the external frame include a first short beam 41 and a second short beam 42. The first short beam 41 and the second short beam 42 are respectively hinged to the corresponding long cross beams 32, so that the first short beam 41 and the second short beam 42 can swing on the horizontal plane. The free end of the first short beam 41 has a slot, and the free end of the second short beam 42 has a head. The head and the slot are fitted by a convex and concave structure. At this time, the two are joined to form the short longitudinal beam 33. When it is necessary to disassemble or connect the internal frame and the external frame, the first short beam 41 and the second short beam 42 are controlled to flip and separate the two. At this time, an unobstructed passage is formed between the two long cross beams 32, and the internal frame can be moved out or in through the unobstructed passage.

[0041] To enable the first short beam 41 and the second short beam 42 to flip, worm gears are provided at their inner ends. At this time, the long cross beam 32 is provided with a flat opening, and the worm gear is located in the flat opening. The center of the worm gear is connected to the long cross beam 32 through a short shaft. At the same time, a worm 43 is provided on the long cross beam 32, and a gear is installed on the worm 43. The worm 43 is arranged parallel to the long cross beam 32 and coupled with the worm gear. When the worm 43 rotates around the central axis, it can cause the worm gear to rotate, thereby causing the first short beam 41 and the second short beam 42 to flip.

[0042] In this embodiment, the adapter 35 is provided with a transmission arm 44, which is provided with an upper toothed section 45 and a lower toothed section 46. Both the upper toothed section 45 and the lower toothed section 46 are composed of toothed convexity. The lower toothed section 46 can mesh with the gear on the worm 43. When the adapter 35 moves downward, the lower toothed section 46 can engage with the gear. Then, as the adapter 35 continues to move downward, the worm 43 can rotate, thereby enabling the first short beam 41 and the second short beam 42 to flip during the downward movement of the adapter 35.

[0043] In this embodiment, the external frame is also provided with two sets of fastening components. The two sets of fastening components are arranged vertically. After the first short beam 41 and the second short beam 42 are separated, the structural stability of the external frame can be maintained by the two sets of fastening components. Specifically, each set of tensioning components includes two co-positioned tension arms, which are located at the same horizontal height. Each co-positioned tension arm includes two arc-shaped tension arms 47, and each arc-shaped tension arm 47 is hinged to the corresponding side limiting arm 31, so that the arc-shaped tension arm 47 can be longitudinally rotated around the hinge point. An outwardly extending arm 48 is provided on the limiting arm 31. A gear disk is shafted on the outward arm 48, and an arc-shaped pull arm 47 is fixed on the gear disk. This gear disk can mesh with the upper tooth section 45 of the transmission arm 44. When the transmission arm 44 moves downward, the gear disk rotates first, which drives the arc-shaped pull arm 47 to flip. One of the arc-shaped pull arms 47 has a concave structure at its free end, while the other arc-shaped pull arm 47 has a convex structure at its free end. When the two arc-shaped pull arms 47 are flipped to their free ends and engage with each other, the convex structure on one arc-shaped pull arm 47 is located in the concave structure on the other arc-shaped pull arm 47.

[0044] See Figure 10 As shown, a low-position cylindrical limiting block and a high-position cylindrical limiting block are provided on the limiting arm 31. The arc-shaped pull arm 47 is located between the low-position cylindrical limiting block and the high-position cylindrical limiting block. When the two arc-shaped pull arms 47 are flipped to their free ends and cooperate with each other, the cylindrical limiting block supports the pull arm. At this time, the arc-shaped pull arm 47 is located above the cylindrical limiting block, and the cylindrical limiting block restricts the arc-shaped pull arm 47 from continuing to flip downward.

[0045] Since there are two sets of fastening components, the two long crossbeams 32 can form a stable structure through the cooperation of the limiting arm 31 and the fastening components. Thus, when it is necessary to separate the inner frame from the outer frame (at this time, the inner frame and the engine it carries are located above the long crossbeams 32), the transmission arm 44 moves downward. First, through the cooperation of the upper tooth section 45 and the gear disk, the arc-shaped tie arm 47 is flipped downward to finally form a tie arm in the same position. Then, as the inner frame moves downward, the first short beam 41 and the second short beam 42 on the longitudinal short beam are separated. Then, the inner frame continues to move downward, so that the inner frame can contact the ground. After the inner frame is separated from the outer frame, the outer frame or the inner frame can be removed.

[0046] In this way, no other lifting equipment is needed when the engine is moved around, and the external frame is not allowed to affect the engine maintenance work (because the external frame is equipped with limit arms 31, which are located on both sides of the engine when the engine is removed from the aircraft).

[0047] Finally, this technical solution includes an intelligent control module, which is connected to the control system via signals. It should be noted that this technical solution does not improve upon the intelligent control module and control system; rather, it utilizes existing intelligent control modules and control systems. For example, the intelligent control module includes: The motor 23 control module controls the servo motor 23 via the CANopen protocol; The six-degree-of-freedom platform kinematics module can realize the forward and inverse kinematics solutions of parallel mechanisms; The dual-platform collaborative control module enables coordinated attitude adjustment of the two engines on the two upper platforms.

[0048] The control system is a dual six-degree-of-freedom platform engine attitude adjustment system, which includes features such as importing custom modules, kinematic models, and a main controller for the engine positioning system.

[0049] Finally, it should be noted that the main improvement in this technical solution is to modify the cabin structure. The power supply and distribution module, heat dissipation module, fire protection module, and intelligent monitoring module all adopt existing technical solutions and products. However, considering the special characteristics of the cabin structure in this solution, their combined application can improve the safety of the container.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
