Description

Technical Field

[0001] This invention relates to the field of emergency rescue transportation technology, and in particular to a modular platform with a support frame. 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] In the prior art, such as the Chinese invention patent application document with publication number CN115557272A, 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 cars, the folding platform is mounted 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 folding platform's range of motion is extremely limited, only able to unfold on one side adjacent to the platform car. Wheeled vehicles need to move closer to the rails and the railway flatcar before transferring via the folding ramp and main platform. The boarding position and method are fixed and monotonous, making it inconvenient to use. Furthermore, in this loading and unloading platform car, the width of the folding ramp and main platform in the unfolded form is affected by the width of the railway flatcar, resulting in a limited platform width. This makes it difficult for vehicles to smoothly and safely pass through the platform for transfer, requiring a high level of driving skill from the vehicle driver. Additionally, tracked vehicles and rescue vehicles are heavy, placing certain demands on the platform's load-bearing capacity.

[0005] Therefore, it is necessary to provide a modular platform that is convenient, quick, safe, and has a high load-bearing capacity. Summary of the Invention

[0006] This invention provides a modular platform with a load-bearing frame, which features the advantages of being able to set up temporary platforms anywhere, having unrestricted construction location, offering diverse relocation methods, being convenient to use, and having high load-bearing capacity. The specific technical solution is as follows:

[0007] A modular platform with a support frame includes platform components, multiple platform components can be spliced ​​together to form a temporary platform; the platform components include a base platform and a top platform disposed directly above the base platform, the distance between the base platform and the top platform and the tilt angle of the top platform relative to the base platform are adjustable, the top surface of the top platform in a horizontal state forms the support surface of the temporary platform, the top surface of the top platform in an inclined state forms the slope of the temporary platform, and a support frame is disposed below the slope formed by the top platform; the support frame includes a support seat and a support plate hinged together, the support plate can rotate relative to the support seat to adjust the tilt angle of the support plate, thereby supporting the top platform at different angles.

The adjusting groove is provided with multiple adjusting protrusions, and the adjustable leg can be engaged with different adjusting protrusions to adjust the tilt angle of the support plate.

[0009] Furthermore, the end of the adjustable leg that engages with the adjustable protrusion is provided with an arc-shaped engaging guide to facilitate the sliding of the adjustable leg into the groove formed by two adjacent adjustable protrusions.

[0010] Furthermore, the support base and the storage locking base are slidably connected. When the support plate is in contact with the support base, the storage locking base can lock the support plate so that the support frame is in the storage state.

[0011] Furthermore, at least two locking pins are fixedly installed on the side of the storage locking seat connected to the support seat. The support seat is provided with locking holes that match the shape of the locking pins. A locking spring is fixedly installed in the locking hole. The locking spring is fixedly connected to the end of the locking pin. The locking spring can provide a pulling force to the storage locking seat to move closer to the support seat, so that the storage locking seat can lock the support plate in the storage state.

[0012] Furthermore, locking plates are provided on both sides of the support plate, and the support plate and the locking plates can be fastened to the storage locking seat to lock the support plate.

[0013] Furthermore, the bearing seat includes two bearing base plates, which are hinged to both sides of the bearing support plate.

[0014] Furthermore, the side of the load-bearing base plate away from the load-bearing support plate is provided with anti-slip protrusions, which can improve the stability of the load-bearing frame.

[0015] Furthermore, the anti-slip protrusions have an inverted trapezoidal structure and are made of rubber.

[0016] Furthermore, a buffer unit is provided on the side of the support plate that contacts the top platform, which can provide cushioning for the top platform.

[0017] This invention features an ingenious structural design and a high degree of automation. It can be assembled and deployed anywhere to create temporary platforms, allowing transport vehicles and wheeled vehicles to move to the ground or railway flatcars via transfer platforms, thus facilitating rapid rescue operations. In addition, the addition of a support frame greatly increases the load-bearing capacity of the temporary platform, meeting the needs of more vehicles. Furthermore, the adjustable-angle support frame can adapt to platforms with different slopes. Moreover, the inclusion of a storage locking seat allows the support plate to be locked, keeping the support frame in a retracted state for convenient transportation and storage.

[0044] To better understand the purpose, function, and specific design of this invention, the modular platform with a support frame of this invention will be described in further detail below with reference to the accompanying drawings.

[0045] like Figures 1-24 As shown, the modular platform used in this invention includes platform components, and multiple platform components can be spliced ​​together to form a temporary platform. The platform component includes a base platform 3, a top platform 4 disposed directly above the base platform 3, and a support component 5 disposed between the base platform 3 and the top platform 4. The support component 5 can adjust the distance between the base platform 3 and the top platform 4 and the tilt angle of the top platform 4 relative to the base platform 3. The top surface of the top platform 3 in a horizontal state forms the bearing surface of the temporary platform, and the top surface of the top platform 3 in an inclined state forms the slope of the temporary platform.

[0046] like Figures 18-21 As shown, the platform components 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.

[0047] In this invention, the transport vehicle 1 is preferably a heavy-duty truck. The transport vehicle 1 includes a transport frame and a driving device located below the transport frame. The transport vehicle 1 can travel at high speed on the ground via the driving device to move to the target location and use the platform components to build a 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 for stacking. Then, the transport vehicle 1 moves along the railway flatcar 7 along the rail 71 to the target location and unloads the platform components to build the transfer platform.

[0048] 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 18-21 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.

[0049] Of course, such as Figure 3 As 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 and the ground through the robotic arm 2 to form a transfer platform for wheeled vehicles and the transport vehicle 1 to pass through.

[0050] 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:

[0051] Firstly, by using the support component 5 to bring the base platform 3 and the top platform 4 closer together, the height distance between the base 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 rack of the transport vehicle 1, thus 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.

[0052] 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.

[0053] 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. This improves loading and unloading efficiency while ensuring the safe handling and transfer of platform components.

[0054] Furthermore, the support component 5 can also tilt the top platform 4 downwards, forming a shape such as Figure 6 He Ru Figure 7 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 14 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 18-21 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.

[0055] 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.

[0056] Specifically, such as Figure 12 and Figure 13 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.

[0057] 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.

[0058] 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.

[0059] Specifically, such as Figure 12 and Figure 13As shown, the bottom surface of the base platform 3 is provided with a notch, the rolling element 31 is a caster 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 or the transport frame.

[0060] 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, its length can be increased to facilitate vehicle passage, while when stacked on a transport rack, its 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. 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.

[0061] Specifically, such as Figure 8-9 As 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 protrusion 441 is fixed below one end of the sandwich support plate 44. The sandwich protrusion 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 protrusion 441.

[0062] 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.

[0063] When platform components need to be stacked on the transport rack, 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 thus the size of the platform components, facilitating 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 16 and Figure 17 As shown, it is attached to 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.

[0064] 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.

[0065] Specifically, such as Figure 10 , Figure 15 as well as Figure 17 As 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.

[0066] 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 14 and Figure 15 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 16-17 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 18-21 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.

[0067] like Figure 22-24 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.
