Description

Technical Field

[0001] This invention relates to the field of emergency rescue transportation technology, and in particular to an emergency vehicle-mounted mobile modular platform. Background Technology

[0002] To achieve rapid transportation of wheeled and tracked vehicles, it is usually necessary to rely on platforms as intermediate carriers to realize the loading, unloading and transfer of wheeled and tracked vehicles between ground and rail vehicles.

[0003] However, during wartime, railways may be destroyed by bombing, preventing railway vehicles from reaching the platforms and making it impossible to unload wheeled vehicles from flatcars. In addition, when carrying out emergency rescue or transporting disaster relief vehicles, it is also necessary to improve the flexibility and timeliness of vehicle loading and unloading. Therefore, in the prior art, such as the Chinese invention patent application document with publication number CN11 5557272A, a mobile railway loading and unloading platform car is disclosed. This device uses a movable folding platform to load and unload vehicles that need to be transported, without relying on traditional fixed platforms. It can complete the loading and unloading of vehicles at any location, thereby facilitating rapid rescue.

[0004] However, in the aforementioned motorized railway loading and unloading platform car, the folding platform is set on the flatcar body via a loading and unloading platform, and is driven by a ball screw assembly to move along the width of the loading platform. Therefore, the range of motion of the folding platform is extremely limited, and it can only be unfolded on one side of the platform car. Wheeled vehicles need to move to a position close to the rails and the railway flatcar before transferring via the folding ramp and the main platform. The boarding position and boarding method are fixed and monotonous, making it inconvenient to use. Moreover, in the unfolded form of the loading and unloading platform car, the width of the folding ramp and the main platform is affected by the width of the railway flatcar, resulting in a limited width of the unfolded platform. It is not easy for vehicles to pass through the platform smoothly and safely for transfer, and a high level of driving skill is required from the vehicle driver.

[0005] Therefore, it is necessary to provide an emergency vehicle-mounted mobile modular platform that is convenient, quick, and safe to use. Summary of the Invention

[0006] This invention provides an emergency vehicle-mounted mobile modular platform, which features the advantages of being able to set up a temporary platform anywhere, with unrestricted setup location, diverse relocation methods, convenient and safe use, and reduced operational requirements for the driver. The specific technical solution is as follows:

[0007] An emergency vehicle-mounted mobile modular platform includes:

[0008] A transport vehicle, the transport vehicle including a transport frame and a driving device disposed below the transport frame;

[0009] A platform assembly, wherein at least two platform assemblies are provided and stacked on the transport frame, and the top of the platform assembly is retractable to adjust its length;

[0010] A robotic arm, mounted on the transport frame, is used to move the platform assembly between the transport frame and the ground;

[0011] The platform components that are transferred to the ground can be detachably connected to form a transfer platform. In the transfer platform, at least two platform components are respectively set horizontally and inclined at the top to allow wheeled vehicles and transport cars to be transferred between railway flatcars and the ground.

[0012] Furthermore, in order to form a transfer platform by splicing platform components, the platform component includes a base platform, a top platform disposed directly above the base platform unit, and a support component disposed between the base platform and the top platform. The support component is used to adjust the distance between the base platform and the top platform and the tilt angle of the top platform relative to the base platform. The top surface of the top platform in a horizontal state forms the bearing surface, and the top surface of the top platform in an inclined state forms the slope.

[0013] Furthermore, to facilitate adjustment of the height and tilt angle of the top platform, the support assembly includes a fixed telescopic unit and a sliding telescopic unit that both extend and retract in the vertical direction. A fixed seat is fixed on the top platform and hinged to the top of the fixed telescopic unit, and a sliding seat is also slidably mounted on the top platform and hinged to the top of the sliding telescopic unit.

[0014] Furthermore, to facilitate the movement of the platform components on the ground and make it easier to connect the platform components by adjusting their positions, the base platform is provided with rolling elements and moving units that drive the rolling elements to move between rolling positions and fixed positions. The rolling elements at the rolling positions are used to support the base platform to lift it off the ground, so as to facilitate the displacement adjustment of the platform components. The rolling elements at the fixed positions are located above the bottom surface of the base platform.

[0015] Furthermore, in order to make the length of the top platform adjustable so that when the top platform is horizontal, the bearing area can be increased, and the top platform can be easily attached to the railway flatcar for easy transfer, while when the top platform is tilted, the slope of the slope can be reduced to facilitate vehicle passage, the top platform includes support plates that are sequentially attached and slidably connected along the first direction, and a pushing unit is provided between two adjacent support plates to drive the relative displacement between them.

[0016] Furthermore, in order to ensure the structural compactness of the top platform when it is stored and to ensure that the top platform has a certain length when it is unfolded, the support plate is provided in three parts, all of which are hollow structures, and the three support plates are sequentially sealed and connected.

[0017] Furthermore, to facilitate the splicing and connection between platform components and to ensure that the top platforms of two adjacent platform components can share the load after splicing, thereby guaranteeing structural strength, load-bearing capacity of the bridge platform, and extending service life, the top platform is equipped with a movable and rotatable mating sleeve at its upper limit. The moving direction of the mating sleeve is perpendicular to the rotating direction, and the rotation axis extends along a direction perpendicular to the first direction and parallel to the bearing surface of the top platform. A bolt is threaded through the inner side of the mating sleeve, and a nut is threaded onto the bolt.

[0018] Furthermore, in order to realize the transfer operation of the platform components between the transport frame of the transport vehicle and the ground or rails, the robotic arm includes a rotating component, a vertical arm, a horizontal arm, a lifting component, a lifting arm and a gripping component connected in sequence. The rotating component drives the vertical arm to rotate around its own axis, the horizontal arm can extend and retract along its own length to adjust its own length, and the lifting component drives the lifting arm to move in the vertical direction.

[0019] Furthermore, to facilitate quick and easy grabbing of the platform component, the grabbing component includes an electromagnet, which magnetically attracts the top of the platform component when energized.

[0020] Furthermore, in order to limit the range of motion of the platform components on the transport frame and prevent the platform components from detaching from the transport frame during the movement of the transport vehicle, a limiting component is also provided on the transport frame. The limiting component is used to cooperate with the lifting arm to surround the platform components stacked on the transport frame.

[0021] This invention features an ingenious structural design and a high degree of automation. A transport vehicle carries the platform components, which are then moved to the ground or railway tracks by a robotic arm. This allows for easy assembly anywhere to form a transfer platform, enabling transport vehicles and wheeled vehicles to move onto railway flatcars. The platform's location is unrestricted, allowing for flexible assembly and diverse methods of moving wheeled vehicles onto railway flatcars. Furthermore, the platform's length is unlimited, accommodating vehicles of varying lengths and facilitating faster and more convenient use, thus promoting rapid rescue operations.

[0022] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0056] To better understand the purpose, function, and specific design of this invention, the emergency vehicle-mounted mobile modular platform of this invention will be described in further detail below with reference to the accompanying drawings.

[0057] like Figures 1-22 As shown, the emergency vehicle-mounted mobile modular platform of the present invention includes:

[0058] The transport vehicle 1 includes a transport frame 11 and a driving device 12 disposed below the transport frame 11;

[0059] Platform components, at least two of which are stacked on transport rack 11, the top of the platform components being extendable to adjust their length;

[0060] Robotic arm 2, which is mounted on transport frame 11, is used to move and transfer platform components between transport frame 11 and the ground.

[0061] like Figures 23-26 As shown, the platform components transferred to the ground can be detachably connected to form a transfer platform. In the transfer platform, at least two platform components are respectively set horizontally and inclined at the top to allow wheeled vehicles and transport cars 1 to be transferred between railway flatcars 7 and the ground.

[0062] In this invention, the transport vehicle 1 is preferably a heavy truck. The transport vehicle 1 can travel at high speed on the ground via the driving device 12 to move to the target location and use the platform components to build the transfer platform. Alternatively, the transport vehicle 1 can travel to the railway flatcar 7 via the transfer platform built by the platform components and stop there. Then, the transport vehicle 1 uses the robotic arm 2 to transport each platform component one by one to its own transport frame 11 for stacking. Then, the transport vehicle 1 moves along the railway flatcar 7 along the rail 71 to the target location and then unloads the platform components to build the transfer platform.

[0063] Specifically, upon reaching the target location, the robotic arm 2 on the transport vehicle 1 can transfer the stacked platform components to the ground, and then assemble the platform components to form a structure as shown in the image. Figures 23-26 The transfer station shown can be used to move transport vehicles 1 and wheeled vehicles between the ground and railway flatcars 7 when the transfer station is built on the ground.

[0064] Of course, such as Figure 5As shown, if the transport vehicle 1 is loaded with a platform component and is traveling on the ground, the transport vehicle 1 can also transfer the platform component between the transport frame 11 and the ground through the robotic arm 2 to form a transfer platform for wheeled vehicles and the transport vehicle 1 to pass through.

[0065] To facilitate the handling and transfer of platform components, the robotic arm 2 includes a rotating assembly 21, a vertical arm 22, a horizontal arm 26, a lifting assembly 23, a lifting arm 24, and a gripping assembly 25 connected in sequence. The rotating assembly 21 drives the vertical arm 22 to rotate around its own axis, the horizontal arm 26 can extend and retract along its own length to adjust its own length, and the lifting assembly 23 drives the lifting arm 24 to move in the vertical direction.

[0066] Specifically, such as Figures 4-8 As shown, the rotating assembly 21 includes a rotating motor 211, which is fixed above the transport frame 11 by a support frame and is positioned downwards. The output end of the rotating motor 211 is fixedly connected to the coaxial center line of the driving sprocket 212. The driving sprocket 212 is driven by a driven sprocket 214 via a chain 213. The driven sprocket 214 is fixed to the bottom of the vertical arm 22 by the coaxial center line. A bearing 14 is provided between the driven sprocket 214 and the transport frame 11. The outer ring of the bearing 14 is fixedly connected to the transport frame 11, and the inner ring is connected to the driven sprocket 214.

[0067] With the above structure, the rotary motor 211 starts and drives the drive sprocket 212 to rotate. The drive sprocket 212 drives the driven sprocket 214 to rotate stably under the support of the bearing 14 through the chain 213. This can drive the vertical arm 22, the horizontal arm 26 and the lifting arm 24 to rotate around the axis of the driven sprocket 214, and adjust the horizontal position of the gripping assembly 25.

[0068] The horizontal arm 26 includes a first rotating arm 261 and a second rotating arm 262 extending in the same horizontal direction. The first rotating arm 261 is fixed to the top of the vertical arm 22. The first rotating arm 261 and the second rotating arm 262 are slidably connected to each other and both are hollow structures. Specifically, the outer circumferential edge of the second rotating arm 262 is sealed to the inner circumferential wall of the first rotating arm 261. A telescopic cylinder 263 is provided in the cavity formed by the first rotating arm 261 and the second rotating arm 262. The cylinder of the telescopic cylinder 263 is fixed to the inner wall of the first rotating arm 261, and the piston rod is fixedly connected to the inner wall of the second rotating arm 262.

[0069] Thus, the first rotating arm 261 and the second rotating arm 262 can surround and protect the telescopic cylinder 263. When the piston rod of the telescopic cylinder 263 moves in extension and retraction, it can drive the second rotating arm 262 to move along its own length direction, thereby realizing the extension and retraction of the horizontal arm 26. Adjusting the length of the horizontal arm 26 can adjust the distance between the lifting arm 24, the gripping component 25 and their rotation axis, that is, the axis of the vertical arm 22.

[0070] The lifting assembly 23 is located at the end of the second rotating arm 262 away from the first rotating arm 261. Specifically, the end of the second rotating arm 262 away from the first rotating arm 261 is provided with a lifting through hole 2621. The lifting assembly 23 includes a lifting motor 231 fixed on the inner wall of the lifting through hole 2621. The lifting motor 231 is a dual-axis output motor, and its two output ends are fixedly connected to a gear 232 along the coaxial center line. The gear 232 meshes with a rack 233, and the rack 233 extends along the vertical direction and is integrally formed on the lifting arm 24.

[0071] After the lifting motor 231 is started, it drives the gear 232 to rotate, which in turn acts on the rack 233, causing the lifting arm 24, which is integrally connected to the rack 233, to move up and down, adjusting the height position of the gripping component 25.

[0072] To ensure smooth vertical movement of the lifting arm 24, both sides of the lifting arm 24 are sealed to the inner walls of the lifting through-hole 2621. The side of the lifting arm 24 facing away from the rack 233 is sealed to the inner wall of the lifting through-hole 2621 away from the lifting motor 231. A guide block 234 with a T-shaped cross-section is integrally formed on the inner wall of the lifting through-hole 2621 away from the lifting motor 231. A strip-shaped through-hole 241 extending along the length of the lifting arm 24 is provided, with a gap between the strip-shaped through-hole 241 and both ends of the lifting arm 24, and it slides in contact with the guide block 234. Through the sliding contact between the guide block 234 and the strip-shaped through-hole 241, and the sealed contact between the lifting arm 24 and the inner walls of the lifting through-hole 2621 on three sides, it is ensured that after the lifting motor 231 is started, the lifting arm 24 drives the gripping assembly 25 to move smoothly vertically.

[0073] To facilitate rapid gripping and release of platform components, the robotic arm 2 of this invention includes a gripping component 25 comprising an electromagnet. When energized, the electromagnet magnetically attracts the top of the platform component. The gripping component 25 is a horizontal plate-like structure. When gripping the platform component, the position of the gripping component 25 is adjusted via the rotating component 21, the telescopic cylinder 263, and the lifting component 23, moving it to a position directly above the top of the platform component. Then, the electromagnet in the gripping component 25 is energized, generating magnetism and attracting the platform component below, thus completing the gripping operation. After the platform component is adjusted to the target position, the electromagnet is de-energized, causing it to lose its magnetism and no longer attract the platform component. Under the gravity of the platform component, the gripping component 25 and the platform component can then quickly separate.

[0074] Preferred, such as Figure 4-6As shown, in another embodiment, the gripping component 25 includes a gripper 8, which can grip the platform component to move it to a target position. The gripper 8 includes a gripper mounting base 81, with a clamping plate 82 movably disposed on each side of the gripper mounting base 81. The two clamping plates 82 are connected to a gripper driving component, which can drive the two clamping plates 82 to move relative to the gripper mounting base 81 to realize the gripping function of the gripper 8.

[0075] Specifically, the gripper drive assembly includes a gripper cylinder 83, the output shaft of which is connected to a gripper connecting rod, which is connected to a clamping plate 82. The extension and retraction of the output shaft of the gripper cylinder 83 can drive the gripper connecting rod to move, thereby driving the clamping plate 82 to move. In this embodiment, a hinge block 84 is fixedly provided at the end of the output shaft of the gripper cylinder 83. The gripper connecting rod includes two first connecting rods 85 and two second connecting rods 86. The two sides of the hinge block 84 are respectively hinged to the ends of the two first connecting rods 85. The ends of the two first connecting rods 85 away from the hinge block 84 are respectively hinged to one of the second connecting rods 86. The ends of the two second connecting rods 86 away from the first connecting rods 85 are connected to the clamping plate 82. Two guide blocks 87 are fixedly provided on the gripper mounting base 81. The guide blocks 87 are slidably connected to the second connecting rods 86. The guide blocks 87 can restrict the movement direction of the second connecting rods 86. The gripper cylinder 83 drives the second connecting rods 86 to move through the first connecting rods 85 to realize the gripping of the clamping plate 82.

[0076] It is worth noting that, in order to save space occupied by the gripper 8 and to improve the stability and reliability of the gripper 8 when gripping the platform components, the guide block 87 in this embodiment is located at the middle position on both sides of the top of the gripper mounting base 81, the hinge block 84 is located on the side close to the lifting arm 24, and the cylinder body of the gripper cylinder 83 is located on the side away from the lifting arm 24, so that when the output shaft of the gripper cylinder 83 retracts, the distance between the two clamping plates 82 increases; when the output shaft of the gripper cylinder 83 extends, the distance between the two clamping plates 82 shortens to grip the items.

[0077] To improve the reliability of the clamping plate 82 during operation, the clamping plate 82 is L-shaped, allowing it to engage with the platform assembly when clamping it. To increase the fault tolerance of the clamping plate 82 when clamping the platform assembly, a guide section with a rounded surface is provided on the horizontal end of the L-shaped clamping plate 82 to facilitate engagement with the platform assembly.

[0078] To prevent the platform components from falling off the side of the transport frame 11 during transport by the transport vehicle 1, a limiting component 13 is also provided on the transport frame 11. The limiting component 13 cooperates with the lifting arm 24 to surround the platform components stacked on the transport frame 11. It should be noted that in this invention, when the platform components are stacked on the transport frame 11, the overall shape is rectangular. Therefore, by using the limiting component 13 and the lifting arm 24 to surround the platform components from all sides, the horizontal movement space of the platform components is restricted to directly above the transport frame 11. Figure 1 As shown, this prevents the platform components from falling off the transport frame 11, thereby ensuring the safe transport of the platform components.

[0079] More specifically, the limiting component 13 includes a first limiting cylinder 131 extending along the length direction of the transport frame 11. The cylinder barrel of the first limiting cylinder 131 is horizontally fixed above the transport frame 11. The piston rod is fixedly connected to a translation column 132. A second limiting cylinder 133 extending along the width direction of the transport frame 11 is provided on both sides of the translation column 132. The cylinder barrel of the second limiting cylinder 133 is fixed on the translation column 132. The piston rod is fixedly connected to a side shift frame 134 extending along the vertical direction. A roller 1321 that fits against the transport frame 11 is provided at the bottom of the translation column 132.

[0080] After the robotic arm 2 moves each platform component from the ground to the transport frame 11 and stacks them, the position of the lifting arm 24 is adjusted so that it moves to the rear of the transport vehicle 1. Then, the two second limit cylinders 133 drive the two side-shifting frames 134 to move in opposite directions, increasing the distance between the two side-shifting frames 134. Then, the first limit cylinder 131 drives the translation column 132 to approach the lifting arm 24 with the support of the roller 1321 until it comes into contact with the stacked platform components. Then, the two second limit cylinders 133 drive the two side-shifting frames 134 to move relative to each other, reducing the distance between the two side-shifting frames 134 until the two side-shifting frames 134 come into contact with the two sides of the platform components. In this way, the translation column 132, the lifting arm 24, and the two side-shifting frames 134 can surround the platform components from the four side walls of the platform components, limiting the horizontal movement space of the platform components and preventing the platform components from falling off the transport frame 11 during transportation.

[0081] Furthermore, the cooperation between the limiting component 13 and the lifting arm 24 ensures that the platform components are neatly stacked on the transport rack 11. Therefore, when the robotic arm 2 grabs the platform components and places them on the transport rack 11, it does not need to deliberately keep the grabbing component 25 above the center of the top of the platform components. This increases the fault tolerance rate of grabbing and releasing the platform components, making the handling and transfer of the platform components more convenient and faster. This is more conducive to the rapid construction of temporary transfer stations, facilitating the passage of wheeled vehicles and enabling rapid emergency rescue.

[0082] To construct a temporary transfer platform for the convenient passage of wheeled vehicles and transport vehicles 1, the platform assembly includes a base platform 3, a top platform 4 positioned directly above the base platform 3, and a support assembly 5 positioned between the base platform 3 and the top platform 4. The support assembly 5 is used to adjust the distance between the base platform 3 and the top platform 4, as well as the tilt angle of the top platform 4 relative to the base platform 3. The top surface of the horizontally positioned top platform 4 forms a bearing surface (e.g., ...). Figure 9 and Figure 10 As shown), the top surface of the inclined platform 4 forms a slope (as shown). Figure 11 and Figure 12 (As shown).

[0083] It should be noted that in this invention, the support component 5 is used to adjust the distance between the base platform 3 and the top platform 4, and can be applied to multiple scenarios, as described below:

[0084] Firstly, by using the support component 5 to bring the bottom platform 3 and the top platform 4 closer together, the height distance between the bottom platform 3 and the top platform 4 is reduced, thereby reducing the height of the platform components. This makes it easier to stack more platform components on the transport frame 11 of the transport vehicle 1, increasing transport efficiency. Furthermore, by increasing the number of platform components, it is beneficial to increase the length and width of the temporary transfer platform formed by splicing the platform components, thereby ensuring the safe passage of wheeled vehicles and transport vehicles 1 through the transfer platform and reducing the requirements for the driver's driving skills.

[0085] Secondly, when the base platform 3 is on the ground, the height of the top platform 4 can be adjusted by the support component 5, thereby adjusting the height of the temporary transfer platform so that the transfer platform can be used for railway flatcars 7 of different heights, thus expanding the scope of use.

[0086] Thirdly, during the transfer of platform components via robotic arm 2, when robotic arm 2 is in a suspended state, the height of the base platform 3 can be adjusted via support component 5, such as... Figure 3 As shown, this allows the base platform 3 to contact the ground, reducing the lifting stroke of the lifting arm 24. It eliminates the need to lower the lifting arm 24 to its lowest position. During the descent of the lifting arm 24, the base platform 3 can be lowered simultaneously via the support assembly 5 until it contacts the ground, rail 71, or transport frame 11. This improves loading and unloading efficiency while ensuring the safe handling and transfer of platform components.

[0087] Furthermore, the support component 5 can also tilt the top platform 4 downwards, forming a shape such as Figure 11 He Ru Figure 12 As shown by the slope, when the inclined platform component of top platform 4 and the horizontal platform component of top platform 4 are spliced ​​together, they can be assembled to form a structure as shown. Figure 19 The temporary transfer platform shown can be placed arbitrarily. It can be used as a top-mounted platform or a side-mounted platform, or it can be sequentially spliced ​​with other temporary transfer platforms to form a structure like... Figures 23-26 The increased size of the transfer platform facilitates the movement of wheeled vehicles and transport vehicles 1 from different locations and in different directions to the railway flatcar 7, or from the railway flatcar 7 to the ground via the transfer platform. This makes loading and unloading vehicles more convenient and faster. Furthermore, the increased size of the transfer platform reduces the driving requirements for vehicle drivers, thereby improving loading and unloading safety.

[0088] To facilitate adjustment of the distance between the top platform 4 and the bottom platform 3, as well as the tilt angle of the top platform 4 relative to the bottom platform 3, the support assembly 5 includes a fixed telescopic unit 51 and a sliding telescopic unit 52, both of which move in a vertical direction. A fixed seat 41 is fixed on the top platform 4 and hinged to the top of the fixed telescopic unit 51. A sliding seat 42 is also slidably mounted on the top platform 4 and hinged to the top of the sliding telescopic unit 52.

[0089] Specifically, such as Figure 17 and Figure 18 As shown, the support assembly 5 includes two fixed telescopic units 51 distributed perpendicular to the direction and a sliding telescopic unit 52 disposed between the two fixed telescopic units 51. The fixed telescopic units 51 and the sliding telescopic unit 52 have similar structures. The fixed telescopic unit 51 includes a fixed cylinder 511 and a fixed telescopic frame 512. The cylinder of the fixed cylinder 511 is fixed above the base platform 3. The piston rod is hinged to one end of the bottom of the fixed telescopic frame 512. The other end of the bottom of the fixed telescopic frame 512 is hinged to the base platform 3. The top end of the fixed telescopic frame 512 is hinged to... There is a fixed base 41, which is fixed to the bottom surface of the top platform 4; the sliding telescopic unit 52 includes a sliding cylinder 521 and a sliding telescopic frame 522. The cylinder of the sliding cylinder 521 is fixed above the bottom platform 3. The piston rod is hinged to one end of the bottom of the sliding telescopic frame 522. The other end of the bottom of the sliding telescopic frame 522 is hinged to the bottom platform 3. The top of the sliding telescopic frame 522 is hinged to a sliding seat 42. The bottom surface of the top platform 4 is provided with a slide rail 451 extending along its own length direction. The slide rail 451 is a T-shaped slide rail 451 that slides and cooperates with the slide seat 42.

[0090] With the above structure, the extension length of the fixed telescopic frame 512 is adjusted by the extension and retraction of the piston rod of the fixed cylinder 511, and the extension and retraction length of the sliding telescopic frame 522 is adjusted by the extension and retraction of the piston rod of the sliding cylinder 521. When the length of the fixed telescopic frame 512 is the same as the length of the sliding telescopic frame 522, the height position of the sliding seat 42 relative to the fixed seat 41 remains unchanged, and the top platform 4 is adjusted to a horizontal state. In this state, the height distance between the top platform 4 and the bottom platform 3 can be adjusted by adjusting the length of the fixed telescopic frame 512 and the length of the sliding telescopic frame 522. When the length of the fixed telescopic frame 512 is different from the length of the sliding telescopic frame 522, the height position of the sliding seat 42 relative to the fixed seat 41 changes, and the sliding seat 42 slides on the slide rail 451. At this time, the top platform 4 is adjusted to an inclined state. The tilt direction and tilt angle of the top platform 4 can be easily adjusted by adjusting the length of the fixed telescopic frame 512 and the length of the sliding telescopic frame 522.

[0091] A further improvement is that the base platform 3 is provided with a rolling element 31 and a moving unit 32 that drives the rolling element 31 to move between the rolling station and the fixed station. The rolling element 31 of the rolling station is used to support the base platform 3 to lift it off the ground so as to facilitate the displacement adjustment of the platform components. The rolling element 31 of the fixed station is located above the bottom surface of the base platform 3.

[0092] Specifically, such as Figure 17 and Figure 18 As shown, the bottom surface of the base platform 3 is provided with a notch, the rolling element 31 is a universal wheel, and the movable unit 32 is a movable hydraulic cylinder. Its cylinder is fixed on the base platform 3, and the piston rod passes through the inner bottom wall of the notch and is connected to a crossbar. The rolling element 31 is located below the crossbar. In the rolling position, the rolling element 31 moves to the bottom of the notch through the movable hydraulic cylinder. While the rolling element 31 is in contact with the ground, it supports the base platform 3 upward and lifts it off the ground, thus facilitating the movement of the platform assembly on the ground. In the fixed position, the rolling element 31 is housed in the notch and located above the bottom surface of the base platform 3. At this time, it is convenient to fix the position of the base platform 3 and prevent the platform assembly from shifting horizontally on the ground and the transport frame 11.

[0093] To facilitate adjustment of the length of the top platform 4, so that when the platform assembly is used as part of a transfer platform, the length can be increased to facilitate vehicle passage, while when stacked on the transport rack 11, the length can be reduced to improve structural compactness and facilitate temporary storage, the top platform 4 includes support plates that are sequentially fitted and slidably connected, and a pushing unit 46 is provided between two adjacent support plates to drive relative displacement between them; there are three support plates, all of which are hollow structures, and the three support plates are sequentially sealed and connected.

[0094] Specifically, such as Figures 13-16As shown, the top platform 4 includes three hollow support plates that are sequentially and sealed together. Among the three support plates, two adjacent support plates are slidably connected, and a pushing unit 46 is provided between the two adjacent support plates to drive relative displacement between them. More specifically, the three support plates, from the inside to the outside, are an inner support plate 43, a sandwich support plate 44, and an outer support plate 45. The pushing unit 46 includes a first electric push rod and a second electric push rod. The first electric push rod is fixed below the outer support plate 45. A sandwich convex plate 441 is fixed below one end of the sandwich support plate 44. The sandwich convex plate 441 is fixedly connected to the telescopic rod of the first electric push rod. The second electric push rod is fixed in the inner cavity of the sandwich support plate 44. Its telescopic rod is fixedly connected to a pushing strip 461. The pushing strip 461 is fixedly connected to the inner wall of the sandwich support plate 44 away from the sandwich convex plate 441.

[0095] With the above structure, the first electric push rod can drive the interlayer support plate 44 and the outer support plate 45 to move relative to each other, and the second electric push rod can drive the inner support plate 43 and the interlayer support plate 44 to move relative to each other.

[0096] When platform components need to be stacked on transport rack 11, the first electric push rod moves the mezzanine support plate 44 closer to the outer support plate 45, and the second electric push rod moves the inner support plate 43 closer to the mezzanine support plate 44, thereby reducing the length of the top platform 4 and the size of the platform components for easier storage. When the top platform 4 is used as a ramp for a temporary transfer platform, the first electric push rod moves the mezzanine support plate 44 away from the outer support plate 45, and the second electric push rod moves the inner support plate 43 away from the mezzanine support plate 44. This allows the inner support plate 43 and the mezzanine support plate 44 to be pushed out, significantly increasing the length of the top platform 4 and correspondingly reducing the slope, thus facilitating the safe passage of wheeled vehicles and transport cars 1 through the transfer platform. Furthermore, when the top platform 4 is horizontal and the pushing unit 46 is facing the railway flatcar 7, the pushing unit 46 can extend either the inner support plate 43 or the mezzanine support plate 44. Figure 24 and Figure 25 As shown, it overlaps the top of the railway flatcar 7 on the side above, ensuring that wheeled vehicles and transport vehicles 1 can pass through the transfer platform more safely and be safely transferred between the railway flatcar 7 and the ground.

[0097] A further improvement is that the top platform 4 is connected to a movable and rotatable mating sleeve 6 at the upper limit. The moving direction of the mating sleeve 6 is perpendicular to the rotating direction. A bolt 63 passes through the inner side of the mating sleeve 6, and a nut 64 is threaded onto the bolt 63.

[0098] Specifically, such as Figures 13-15As shown, elongated blind holes 452 are provided on both sides of the inner support plate 43 away from the outer support plate 45, and on both sides of the outer support plate 45 away from the inner support plate 43. The opening of the elongated blind hole 452 is covered by an elongated waist ring 65 that is fixedly connected to its circumferential inner wall and spaced from its inner bottom wall. Both the elongated waist ring 65 and the elongated blind hole 452 extend along the extension and contraction direction of the support plate. The inner side of the elongated waist ring 65 has an integrally formed strip-shaped hole extending along its own length direction. The mating sleeve 6 is fixedly connected to a mating rod 61 that extends perpendicular to its axial direction. The end of the mating rod 61 away from the mating sleeve 6 is integrally connected to a mating protrusion 62. The mating rod 61 passes through the inner side of the strip-shaped hole. The outer diameter of the mating rod 61 is smaller than the width of the strip-shaped hole, and the outer diameter of the mating protrusion 62 is larger than the width of the strip-shaped hole. The mating protrusion 62 is sandwiched between the elongated waist ring 65 and the inner bottom wall of the elongated blind hole 452. In this way, the two docking sleeves 6 are respectively connected to the inner support plate 43 and the outer support plate 45 for positioning. Since the width of the strip hole is between the outer diameter of the docking rod 61 and the inner diameter of the docking protrusion 62, it facilitates the rotation and movement of the docking sleeve 6. The direction of movement is perpendicular to the direction of rotation, and the axis of rotation extends along the direction perpendicular to the extension and contraction direction of the support plate and parallel to the bearing surface of the top platform 4.

[0099] Based on the above factors, adjacent platform components can be spliced ​​at the ends or sides. Specifically, when two platform components are spliced ​​together and both sides of the top platform 4 are flush, such as... Figure 19 and Figure 20 As shown, by adjusting the position and direction of the adjacent mating sleeves 6 so that their center lines coincide, the bolts 63 are passed through and the nuts 64 are screwed in; and when the two platform components are spliced ​​together and the two ends of the top platform 4 are flush, as shown... Figure 21-22 As shown, after adjusting the angle and direction, the mating sleeves 6 at adjacent positions pass through the bolts 63 and are screwed into the nuts 64, thus connecting the two adjacent top platforms 4 and achieving the splicing of two adjacent platform components. Furthermore, since the two top platforms 4 share the load after being connected by the bolts 63 and nuts 64, when used as... Figures 23-26 After the transfer platform is completed, the top platform 4 together bear the pressure from above, which can greatly increase the structural strength and load capacity of the transfer platform, thereby extending the service life of the platform components.

[0100] like Figure 30-32 As shown, in order to improve the load-bearing capacity of the top platform 4 when it is used as a slope, a support frame 9 is provided below the slope of the top platform 4. The support frame 9 can support the embedded support plate 43 and the mezzanine support plate 44 to improve the load-bearing capacity of the embedded support plate 43 and the mezzanine support plate 44.

[0101] Specifically, the support frame 9 includes a support seat 91 and a support plate 92 that are hinged together. The support plate 92 can rotate relative to the support seat 91 to adjust the tilt angle of the support plate 92, thereby providing support for the embedded support plate 43 and the interlayer support plate 44.

[0102] The support plate 92 is provided with an adjustable leg 93 on the side near the support seat 91, and the support seat 91 is provided with an adjusting groove 94 on the side near the support plate 92. The adjusting groove 94 is provided with multiple adjusting protrusions, and the adjusting leg 93 can be engaged with different adjusting protrusions to adjust the tilt angle of the support plate 92.

[0103] Preferably, the support base 91 and the storage locking base 95 are slidably connected. When the support plate 92 is in contact with the support base 91, the storage locking base 95 can lock the support plate 92, so that the support frame 9 is in a stored state, facilitating the transportation and storage of the support frame 9. At least two locking pins 96 are fixedly provided on the side of the storage locking base 95 connected to the support base 91. The support base 91 is provided with locking holes that match the shape of the locking pins 96. A locking spring is fixedly provided in the locking hole. The locking spring is fixedly connected to the end of the locking pin 96. The locking spring can provide a pulling force to the storage locking base 95 to move closer to the support base 91, so that the storage locking base 95 can lock the support plate 92 in the stored state. In addition, when the support plate 92 is in the supported state, the storage locking base 95 can also improve the stability of the support base 91.

[0104] Preferably, the support base 91 includes two support base plates, which are hinged to both sides of the support plate 92. Using two support base plates can reduce the requirements for ground flatness and make the support frame 9 more stable and reliable during use.
