[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0055] In the face of natural disasters, it is common for initial rescue vehicles (such as ambulances, search and rescue vehicles, and supply transport vehicles) to be unable to reach the rescue site in time, for helicopters to be unable to land at the nearest ground, and for trains to be unable to stop at stations. When faced with these situations, problems are usually solved by manpower, such as walking to the rescue site, carrying rescue supplies to the rescue site, transferring injured people from distant locations to rescue vehicles or helicopters, and unloading supplies from trains. All of these lead to a significant waste of rescue time and personnel, and seriously restrict rescue efficiency.

[0056] like Figure 1As shown, the present invention provides a multi-functional application platform 10 and an emergency rescue auxiliary vehicle. The emergency rescue auxiliary vehicle includes a vehicle body 20 and a multi-functional application platform 10. The vehicle body 20 has a load-bearing surface, and the multi-functional application platform 10 can be stored on the load-bearing surface. During emergency rescue, the emergency rescue auxiliary vehicle can be driven to the emergency rescue area. When faced with situations such as roads or bridges being damaged and impassable, helicopters being unable to land, or trains not stopping at stations, the multi-functional application platform 10 can be unloaded from the vehicle body 20 and assembled into a functional platform that meets the needs of the above-mentioned different situations.

[0057] like Figures 1-4 , Figure 9As shown, in some embodiments, the multifunctional application platform 10 includes at least two first platform plates 11 and a mobile lifting frame 12. Each first platform plate 11 includes a first plate body 111, a first connecting mechanism 112, and a first supporting mechanism 113. The first connecting mechanism 112 is disposed on at least one side of the first plate body 111 and can be detachably connected to the other first plate body 111. The first supporting mechanism 113 is at least partially telescopic and its upper end is connected to the first plate body 111 and used to support the first platform plate 11. The mobile lifting frame 12 includes a frame main body. The invention comprises a frame body 121, at least two first lifting mechanisms 122, multiple second lifting mechanisms 123, and multiple casters 124. Each first lifting mechanism 122 is mounted on the frame body 121 and has at least two bearing ends for supporting one end of a first platform plate 11. The at least two bearing ends have a first state located inside the frame body 121 and arranged sequentially from top to bottom, and a second state moved to the outside of the frame body 121. The multiple second lifting mechanisms 123 are all vertically connected to the frame body 121 at their upper ends and connected to the multiple casters 124 at their lower ends. The invention connects multiple first platform plates 111 sequentially into a whole through a first connecting mechanism 112, thereby splicing them into a platform for vehicles to pass through, goods to be unloaded, and helicopters to dock. In different application scenarios, multiple first platform plates 11 can be used as needed, and a retractable first support mechanism 113 is used to meet the support requirements of different ground heights, ensuring that the spliced ​​platform can meet the needs of the above-mentioned different situations. Meanwhile, the mobile lifting frame 12 of the present invention realizes the loading of the first platform plate 11 on the vehicle body 20 and the splicing during application through the cooperation of the frame body 121, the first lifting mechanism 122, the second lifting mechanism 123 and the moving wheels 124, which avoids the use of additional hoisting equipment and simplifies the operation. Specifically, in the first state, at least two bearing ends of the first lifting mechanism 122 can sequentially bear at least two first plate bodies 111 from top to bottom, enabling multiple first plate bodies 111 to be sequentially carried in the frame body 121 from top to bottom. The movable lifting frame 12 and the first platform plate 11 are placed on the bearing surface of the vehicle body 20. When needed, the second lifting mechanism 123 of the movable lifting frame 12 can be lowered so that the movable wheels 124 support the ground, thereby unloading the first platform plate 11 from the vehicle body 20 and moving it to the application position. During the transition from the first state to the second state, its bearing ends can sequentially lower multiple first platform plates 11 to different positions to facilitate the splicing of the first platform plates 11. During the transition from the second state to the first state, multiple first platform plates 11 can be sequentially loaded into the frame body 121, and the frame body 121 carrying the first platform plates 11 can be loaded onto the bearing surface of the vehicle body 20 through the movable wheels 124 and the second lifting mechanism 123.

[0058] like Figure 1 , Figure 9As shown, in some preferred embodiments, the frame body 121 is rectangular, and at least two first lifting mechanisms 122 are respectively installed on opposite sides of the frame body 121. The frame body 121 approximately matches the load-bearing surface of the vehicle body 20 to improve the utilization rate of the load-bearing surface on the chassis of the vehicle body 20. Specifically, the frame body 121 can be configured with a length approximately the same as the load-bearing surface, while its width is slightly larger than the load-bearing surface so that the second lifting mechanism 123 can drive the moving wheels 124 to support the ground. In some more preferred embodiments, four first lifting mechanisms 122 can be configured, and they are symmetrically installed in pairs on both sides of the frame body 121 relative to the width of the vehicle body 20.

[0059] like Figures 9-10 As shown, in some embodiments, the first lifting mechanism 122 can be configured to have the aforementioned first and second states and satisfy the loading and unloading of the first platform plate 11, and can be any device in the prior art capable of achieving the above functions; in other embodiments, the first lifting mechanism 122 includes a chain 122a vertically rotatably mounted on the frame body 121, a driving member 122b for driving the chain 122a to rotate, and at least two bearing hooks 122c sequentially arranged along the length direction of the chain 122a, each bearing hook One end of hook 122c is connected to chain 122a, and the other end extends away from chain 122a to form a bearing end. It can drive chain 122a to rotate forward via drive member 122b, causing the bearing hook 122c to move downwards until it flips to the outside of frame body 121, or drive chain 122a to rotate in the opposite direction, causing the bearing hook 122c to flip to the inside of frame body 121 and continue moving upwards. The bearing end of the bearing hook 122c can cooperate to load and unload the first platform plate 11 within frame body 121. It is easy to understand that drive member 122b can use existing conventional drive methods, such as a hydraulic motor, to drive chain 122a to rotate. Chain 122a can be rotatably mounted on frame body 121 by engaging with two gears on frame body 121.

[0060] In some embodiments, the first support mechanism 113 can be adopted in any manner existing in the art, as long as it can support the first plate body 111 at different heights, such as a hydraulic telescopic support frame or a jack-type telescopic support frame; Figures 6-7As shown, in some preferred embodiments, the first support mechanism 113 includes a fixed cylinder 113a, a plurality of telescopic joints 113b, and a support base 113c. The fixed cylinder 113a is detachably embedded in the first plate body 111. The plurality of telescopic joints 113b are all cylindrical and are slidably sleeved from the outside to the inside. The outer wall of the outermost telescopic joint 113b is threadedly engaged with the inner wall of the fixed cylinder 113a, and the top of the outermost telescopic joint 113b has a groove for driving the telescopic joint 113b to rotate relative to the fixed cylinder 113a. The drive unit b1 has its lower end of the inner telescopic joint 113b connected to the support base 113c. The side wall of the telescopic joint 113b has multiple telescopic grooves arranged sequentially along its circumference. The outer wall of the telescopic joint 113b has multiple protrusions b2. Each protrusion b2 on the telescopic joint 113b extends into the telescopic groove of its adjacent telescopic joint 113b. Each telescopic groove includes a guide groove b3 arranged along the axis of the telescopic joint 113b and a support groove b4 that communicates with the bottom of the guide groove b3 and is recessed upward. In practical applications, multiple telescopic joints 113b can extend by sliding the protrusion b2 along the telescopic groove into the support groove b4, and retract by sliding the protrusion b2 along the telescopic groove to the top of the guide groove b3. The extension height of the multiple telescopic joints 113b is adjusted by the number of telescopic joints 113b in the extended and retracted states. When the multiple telescopic joints 113b have extended to approximately the required height, the drive unit b1 can be rotated to drive the outermost telescopic joint 113b to rotate relative to the fixed cylinder 113a, thereby driving all telescopic joints 113b to move downwards until the support base 113c supports the ground, thus meeting the adjustment needs for different heights. It is easy to understand that the drive unit b1 can be a drive groove or a drive protrusion, in which case it can be driven by a wrench to rotate, or it can be other drive methods, such as a handwheel, in which case it can be driven by a handwheel. Figure 8 As shown, in some preferred embodiments, the first support mechanism 113 further includes a thrust bearing 113d and at least one handle 113e, wherein at least one handle 113e is arranged sequentially along the circumference of the fixed cylinder 113a and one end is vertically connected to the fixed cylinder 113a. The handle 113e can drive the fixed cylinder 113a to rotate so as to extend or retract the outermost telescopic joint 113b, which helps to realize the rapid extension and retraction of the first support mechanism 113.

[0061] In some embodiments, the first connecting mechanism 112 can be implemented using existing conventional methods to achieve a detachable connection between the two first plate bodies 111. For example... Figures 2-3 As shown, in some preferred embodiments, the first connecting mechanism 112 may employ a permanent magnet, which can be connected to another permanent magnet on a first plate body 111 via a permanent magnet on the first plate body 111 to achieve a detachable connection; such as Figures 5-6As shown, in some other preferred embodiments, the first connecting mechanism 112 includes a magnetic chuck 112a, a guide hook 112b, and an automatic retractable cable box. The magnetic chuck 112a is embedded in a mounting groove on one side of the first plate body 111 and partially protrudes from the mounting groove. The magnetic chuck 112a has a magnetic hook a11 for adjusting the magnetic direction of the magnetic force of the magnetic chuck 112a. The guide hook 112b is vertically arranged and located at the end of the magnetic chuck 112a away from the mounting groove. The automatic retractable cable box is installed on the first plate body 111 and its driving end is connected to the magnetic hook a11. The other side of the first plate body 111 has a connecting groove that cooperates with the magnetic chuck 112a and the guide hook 112b. The above method helps to improve the convenience and stability of splicing the first plate body 111. That is, when splicing, the first plate body 111 can be horizontally placed, and the second plate body 111 can be moved to one side above it, with the guide hook 112b and the magnetic chuck 112a facing the connecting groove. The first plate body 111 is then lowered, and under the guidance of the guide hook 112b, both the guide hook 112b and the magnetic chuck 112a are inserted into the connecting groove 112d. In order to facilitate the insertion of the guide hook 112b into the connecting groove 112d, the guide hook 112b can be set below the magnetic chuck 112a. However, when the automatic retractable cable box is activated, it pulls the guide hook 112b to adjust the magnetic direction of the magnetic chuck 112a, so that the magnetic chuck 112a is attracted to the first plate body 111. In some other preferred embodiments, a slot can be provided below the magnetic chuck 112a to facilitate its engagement with the track. Therefore, when the magnetic chuck 112a is attached to the first plate body 111, it can also be attached to the track, which helps improve its stability when installed as a train platform. Furthermore, the connecting slot 112d can be shaped like a "7". This connecting slot 112d can consist of a first slot that runs vertically through the first plate body 111 and a second slot located on the side wall of the first plate body 111 and communicating with the first slot. This facilitates the connection by allowing the magnetic chuck 112a to overlap in the second slot while the guide hook 112b can be inserted into the first slot, preventing the magnetic chuck 112a from detaching from the second slot and further improving the stability and reliability of the connection. It is worth noting that the automatic retractable cable box in the first connecting mechanism 112 is not a necessary component; the magnetic hook a11 can also be manually adjusted to adjust the magnetic direction of the magnetic chuck 112a.

[0062] like Figure 12As shown, in some preferred embodiments, in order to improve the loading efficiency of the first plate body 111, the movable lifting frame 12 further includes a guide mechanism 125. The guide mechanism 125 includes a fixed frame 125a, a guide rail 125b, a guide block 125c, a screw 125d, and a drive body 125e. The fixed frame 125a is detachably installed on the frame body 121. The guide rail 125b is horizontally arranged and one end is fixedly connected to the fixed frame 125a. The guide block 125c is slidably sleeved on the guide rail 125b. One end of the screw 125d is rotatably connected to the fixed frame 125a, and the other end is threadedly engaged with the guide block 125c. The drive body 125e is connected to the screw 125d relative to one end of the fixed frame 125a. When unloading the first plate body 111, the drive body 125e can drive the screw 125d to rotate, thereby causing the guide block 125c to retract, so as not to affect the unloading of the first plate body 111. When loading the first plate body 111, the drive body 125e can drive the screw 125d to rotate, thereby causing the guide block 125c to move to protrude from the guide rail 125b. Therefore, when loading the first plate body 111, when the first plate body 111 to be loaded abuts against the guide block 125c, the first lifting mechanism 122 can be activated for loading. As a preferred embodiment, the guide block 125c has a guide surface layer c11 with multiple rollers embedded in it. The guide surface c11 can at least partially protrude to the inside of the frame body 121. It can protrude from the guide rail and then from the inside of the frame body 121 to guide the first plate body 111 to be loaded. The guide surface c11 with rollers can reduce the friction on the first plate body 111.

[0063] like Figure 1 , Figures 13-15As shown, in some preferred embodiments, the multi-functional application platform 10 further includes an auxiliary bridge 13 and a second platform plate 14. The auxiliary bridge 13 is wedge-shaped and has an inclined auxiliary surface 13a. The second platform plate 14 includes a second plate body 141, a second connecting mechanism 142, and a third connecting mechanism 143. The second connecting mechanism 142 is disposed on both sides of the second plate body 141 and is used for detachable connection with the higher side of the auxiliary bridge 13 relative to the auxiliary surface 13a. The third connecting mechanism 143 is disposed on both sides of the second platform plate 14 and is used for detachable connection with the first plate body 111. The auxiliary bridge 13 with the auxiliary surface 13a facilitates the movement of materials or vehicles onto the second platform plate 14 and the first platform plate 11, while the second platform plate 14 facilitates the transition connection between the auxiliary bridge 13 and the first platform plate 11, improving the ease of connection. In some preferred embodiments, the second connecting mechanism 142 includes a second double ear 142a that engages with a first single ear 131 on the auxiliary bridge 13, a second single ear 142b that engages with the first double ear 132 on the auxiliary bridge 13, a first pin 142c that engages with insertion holes passing through the first single ear 131 and the second double ear 142a, a second pin 142d that engages with insertion holes passing through the second single ear 142b and the first double ear 132, and a hydraulic pusher 142e. The hydraulic pusher 142e is embedded in one side of the second plate body 141 and at least partially protrudes from the second plate body 141 and extends into the guide fixing hole 13b on the auxiliary bridge 13. It is readily understood that the loading and unloading requirements of the second platform plate 14 can be met by increasing the number of carrying hooks 122c on the first lifting mechanism 122. Since the loading and unloading method of the second platform plate 14 on the mobile lifting frame 12 is roughly the same as that of the first platform plate 11, it will not be described in detail here. The first pin 142c and the second pin 142d can be either hydraulic pins or ordinary pins. The first pin 142c and the second pin 142d can be located on the second plate body 141 or on the auxiliary bridge 13; this invention does not limit their placement. Furthermore, to improve the stability of the connection between the hydraulic jacking component 142e and the auxiliary bridge 13, a locking hole can be formed at the front end of the hydraulic jacking component 142e. When the front end of the hydraulic jacking component 142e is inserted into the guide fixing hole 13b, the hydraulic pin inside the auxiliary bridge 13 can be inserted into the locking hole to lock and fix the hydraulic jacking component 142e within the guide fixing hole 13b. It is worth noting that the third connecting mechanism 143 can adopt a structure that cooperates with the first connecting mechanism 112. For example, when the first connecting mechanism 112 is a permanent magnet, the third connecting mechanism 143 can also be a permanent magnet. When the first connecting mechanism 112 adopts a magnetic chuck 112a, a guide hook 112b and an automatic retractable cable box, the third connecting mechanism 143 can also adopt the same method to cooperate with it.In addition, the second platform plate 14 also includes multiple second support mechanisms. Each second support mechanism is at least partially retractable and its upper end is connected to the second plate body 141 to support the second platform plate 14. The second support mechanisms are largely the same as the first support mechanism 113, and will not be described in detail here. It is understood that the second connecting mechanism 142 and the third connecting mechanism 143 may also be respectively disposed on opposite sides of the second plate body 141.

[0064] like Figure 16 As shown, in some preferred embodiments, the multifunctional application platform 10 further includes a third platform plate 15. The third platform plate 15 includes a third plate body 151, a rotating base plate 152, a rotating component 153, and a plurality of fourth connecting mechanisms 154. The rotating base plate 152 is mounted on the top of the frame body 121. The third plate body 151 is arranged parallel to the rotating base plate 152 and one end rotates to cover the rotating base plate 152. The rotating component 153 is used to drive the third plate body 151 to rotate relative to the rotating base plate 152. At least one of the plurality of fourth connecting mechanisms 154 is disposed at one end of the third plate body 151 and is used to be detachably connected to the first plate body 111. At least one of the plurality of fourth connecting mechanisms 154 is disposed at the other end of the third plate body 151 and is used to be detachably connected to external equipment. In practical applications, since the support height of the first support mechanism 113 may be limited, a third platform plate 15 is provided on the top of the mobile lifting frame 12. This third platform plate 15 utilizes the height of the frame body 121 itself and the extensibility of the second lifting mechanism 123 to achieve a higher load-bearing height, meeting the requirements for higher load-bearing heights. In some preferred embodiments, the mobile lifting frame 12 further includes multiple third lifting mechanisms 126. The lower end of each third lifting mechanism 126 is connected to the frame body 121, and the upper end is detachably hinged to the bottom of the rotating base plate 152. The height and inclination of the third platform plate 151 can be further adjusted through the third lifting mechanism 126 to meet different height requirements. In some preferred embodiments, each third platform plate has a connecting structure at both ends for detachable connection to another third platform plate. This facilitates the sequential connection of the third platform plates on the mobile lifting frames when multiple mobile lifting frames are arranged in sequence, allowing them to be directly spliced ​​to form a platform for vehicle passage.

[0065] In practical applications, to facilitate the movement of the mobile lifting frame 12 and the crossing of obstacles, at least six second lifting mechanisms 123 are provided. Four of the second lifting mechanisms 123 are respectively located at the four corners of the frame body 121, and the other second lifting mechanisms 123 are arranged in pairs on opposite sides of the middle of the frame body 121. That is, the second lifting mechanisms 123 are arranged on opposite sides of the frame body 121 along the length of the vehicle body 20. The two second lifting mechanisms 123 at one end of the mobile lifting frame 12 are in a retracted state, while the other four second lifting mechanisms 123 are in an extended state, so that one end of the mobile lifting frame 12 can pass over the obstacle. Then, the second lifting mechanisms 123 at the four corners extend to support the ground, while the two second lifting mechanisms 123 in the middle retract to pass through the obstacle. Finally, the second lifting mechanism 123 at the other end of the mobile lifting frame 12 retracts to pass through the obstacle. It is worth noting that, under normal circumstances, setting a second lifting mechanism 123 at each of the four corners of the frame body 121 is sufficient to meet its conventional function. However, setting six or more second lifting mechanisms 123 can help improve its ability to cross obstacles. The specific number of these mechanisms can be installed according to actual needs, with six being preferred.

[0066] When used on railway platforms, in order to facilitate the movement of the lifting frame 12 and ensure its full functionality, such as Figure 9 , Figure 11 As shown, the mobile lifting frame 12 also includes a plurality of corresponding fourth lifting mechanisms 127 and a plurality of rail guide wheels 128. The upper end of each fourth lifting mechanism 127 is connected to the frame body 121 and the lower end is connected to the rail guide wheel 128. It can be supported on the rail by the rail guide wheel 128 to facilitate movement and improve support stability. In a specific configuration, the plurality of fourth lifting mechanisms 127 can be arranged between the two second lifting mechanisms 123 in the middle and the two second lifting mechanisms 123 located at one end of the mobile lifting frame 12, so that the mobile lifting frame 12 can cross the railway obstacle and cooperate with the track.

[0067] like Figure 1 As shown, another aspect of the present invention provides an emergency rescue auxiliary vehicle, including a vehicle body 20 and a multi-functional application platform 10 described in any of the above embodiments. The vehicle body 20 has a bearing surface, and the multi-functional application platform 10 can be housed in the bearing surface.

[0068] like Figures 17-18As shown, in some preferred embodiments, in order to facilitate the loading and unloading of the multi-functional application platform 10 from the vehicle body 20, the emergency rescue auxiliary vehicle also includes a rotating frame 30. The rotating frame 30 includes a fixed guide rail 31, a sliding base 32, a rotating power mechanism 33, and a rotating bracket 34. There are two fixed guide rails 31, which are laid parallel to each other along the length of the vehicle body 20 on the bearing surface. The two fixed guide rails 31 have grooves 31a on opposite sides. The two ends of the sliding base 32 are respectively installed in the two grooves 31a. The lower end of the rotating power mechanism 33 is connected to the sliding base 32, and the upper end is connected to the rotating bracket 34 that is slidably supported on the upper side of the fixed guide rail 31 and is used to drive the rotating bracket 34 to rotate relative to the fixed guide rail 31. The multi-functional application platform 10 is at least partially housed in the rotating bracket 34. In a specific configuration, the side of the bearing surface closest to the front of the vehicle body 20 is used to install the fixed guide rail 31, while the other side can be used to place the auxiliary bridge 13. When the multi-functional application platform 10 needs to be unloaded from the vehicle body 20, the linear drive mechanism on the vehicle body 20 can drive the multi-functional application platform 10 to move a certain distance along the fixed guide rail 31 towards the rear of the vehicle body 20. Then, the rotary power mechanism 33 drives the rotating bracket 34 to rotate 90°, and the second lifting mechanism 123 of the movable lifting frame 12 can then be extended to support it on the ground. It is easy to understand that the linear drive mechanism can adopt existing conventional methods, such as chains, linear motors, and hydraulic cylinders, and the rotary power mechanism 33 can also adopt existing conventional methods that can drive the rotating bracket 34 to rotate relative to the sliding base 32. In order to improve the stability of the auxiliary bridge 13 fixed on the vehicle body 20, the fixed guide rail 31 has a vertically arranged slot at one end near the rear of the vehicle body 20. The slot cooperates with the first single ear 131 and the second single ear 132 of the auxiliary bridge 13. At the same time, a guide structure for supporting the auxiliary bridge 13 to be lifted or lowered can be provided at the bottom of the auxiliary bridge 13. That is, when the auxiliary bridge 13 is placed on the vehicle body 20, the first single ear 131 and the second single ear 130 can cooperate with the slot on the fixed guide rail 31 respectively and be connected by a pin. When it is necessary to unload or load from the vehicle body 20, the push hydraulic rod 22 on the vehicle body 20 can cooperate with the guide structure on the auxiliary bridge 13 to lift or lower the auxiliary bridge 13.

[0069] In some preferred embodiments, the rotary power mechanism 33 includes a rotary seat and a drive assembly. The lower end of the rotary seat is rotatably connected to the sliding base 32, and the upper end is fixedly connected to the rotary support 34. The outer periphery of the rotary seat is provided with teeth. The drive assembly consists of a gear and a motor or hydraulic motor. The gear meshes with the teeth on the outer periphery of the rotary seat. The motor or hydraulic motor fixed on the sliding base 32 drives the gear to rotate, thereby driving the rotary seat to rotate.

[0070] For ease of explanation, the following will use the construction of a train platform as an example: Figures 19-21As shown, the emergency rescue auxiliary vehicle is driven to the side of the railway track and stopped. The hydraulic support legs 21 of the car body 20 are extended and supported on the ground to improve the support stability of the car body 20. The sliding base 32 is driven to move a set distance along the slide groove 31a of the fixed guide rail 31 towards the rear of the car body 20. The rotating power mechanism 33 is controlled to drive the rotating bracket 34 to rotate, thereby driving the movable lifting frame 12 carrying the first platform plate 11, the second platform plate 14 and the third platform plate 15 to rotate, so that one end of the movable lifting frame 12 rotates above the rail. The sliding base 32 continues to move until the second platform plate 14 on the movable lifting frame 12 is roughly aligned with the auxiliary bridge 13 located at the rear of the bearing surface. However, the hydraulic rod at the rear of the car body 20 pushes the vehicle. 22. The auxiliary bridge 13 is lifted so that the first single ear 131 and the first double ear 132 on the auxiliary bridge 13 engage with the second double ear 142a and the second single ear 142b of the second connecting mechanism 142, respectively. The first pin 142c and the second pin 142d are inserted, and the hydraulic pusher 142e of the second connecting mechanism 142 is pushed into the guide fixing hole 13b of the auxiliary bridge 13. The hydraulic pin inside the auxiliary bridge 13 is then inserted into the locking fixing hole at the front end of the hydraulic pusher 142e. Next, the second lifting mechanism 123 of the driving mobile lifting frame 12 extends to support the moving wheel 124 on the ground and lifts the frame body 121, the auxiliary bridge 13, and the second platform plate 14 to detach from the vehicle body 20. The vehicle body 20 is then moved forward. However, the second lifting mechanism 123 is activated and retracted until the rail guide wheel 128 is close to the rail. The fourth lifting mechanism 127 is activated until the rail guide wheel 128 is supported against the two rails. The second and fourth lifting mechanisms 123 and 127 are retracted, and the frame body 121 is moved to the specific installation position via the rail guide wheel 128. Then, the first lifting mechanism 122 is activated until the second platform plate 14 is placed on the rail. The magnetic direction of the magnetic chuck 112a on the third connecting mechanism 143 is adjusted and it is made to adhere to the rail. The second lifting mechanism 123 is activated until the moving wheel 124 is supported on the ground, and the rail guide wheel 128 is disengaged from the rail. The frame body 121 is moved to one side of the second platform plate 14, and a first platform plate is lowered. 11. The guide hook 112b of the first platform plate 11 is inserted into the insertion slot of the second platform plate 14. The magnetic direction of the magnetic chuck 112a of the first platform plate 11 is adjusted and it is attracted to the rail and the second platform plate 14. In order to improve the accuracy of the connection between the first platform plate 11 and the second platform plate 14, a limit switch can be set on the frame body 121. Continue to move the frame body 121 and put down all or as many first platform plates 11 in sequence. Put down the first support mechanism 113 and the support mechanism and support them on the ground. At the same time, retract the hydraulic pin in the auxiliary bridge 13 and the hydraulic pusher 142e in the second platform plate 14. The auxiliary bridge 13 rotates relative to the second plate body 141 until it touches the ground.Finally, the mobile frame body 121 to one side of the first platform plate 11 at the end can be raised and lowered by the second lifting mechanism 123 and the third lifting mechanism 126 to adjust the height and tilt of the third platform plate 15, thereby meeting the needs of loading or unloading materials at the end; wherein, for example; Figure 22 As shown, to facilitate the rapid transfer of materials on the multi-functional application platform 10, pulley-type guide rails can be installed on the first platform plate 11, the second platform plate 14, and the third platform plate 15. After the materials are loaded or unloaded, multiple first platform plates 11, second platform plates 14, and auxiliary bridges 13 can be loaded into the frame body 121 and then loaded onto the vehicle body 20 via the mobile lifting frame 12. The loading method is roughly the same as the platform construction method described above, only the operation steps are roughly reversed, and will not be described in detail here.

[0071] When the multi-functional application platform 10 of the present invention is used on roads, bridges, or helipads, the connection method is roughly the same as that of the first platform plate 11 and the second platform plate 14 described above. The multi-functional application platform 10 is supported on the ground and has a cross-section for vehicles to pass through or helicopters to land. It is worth noting that for bridges or road surfaces requiring a larger support height, such as... Figures 23-24 As shown, multiple mobile lifting frames 12 can be arranged sequentially, and the third platform plates 15 on the mobile lifting frames 12 can be connected end to end in sequence. The tilt angle can be adjusted to meet the needs of different scenarios. Furthermore, as... Figure 25 As shown, multiple third platform panels 15 and / or multiple first platform panels 11 can be tilted or horizontally spliced ​​together to form a house that is roughly tent-shaped, or as shown in the diagram. Figure 26 As shown, multiple third platform panels 15 and / or multiple first platform panels 11 can be individually supported to form an independent tent, and canvas can be installed around the perimeter and in the gaps to facilitate its use as a temporary house; alternatively, the first platform panels 11 or the third platform panels 15 can be arranged at an angle and a baffle can be formed by using the first support mechanism 113 or the movable lifting frame 12 on one side to temporarily shield against wind, rain and snow.

[0072] This invention uses a first connecting mechanism and a first supporting mechanism to splice multiple first plate main bodies to form different types of application platforms to meet different application needs such as rescue vehicle passage, railway platform unloading of materials, and helicopter docking. It also uses a mobile lifting frame to realize the loading, unloading and splicing of the first platform plates on the vehicle body, which has low space occupancy and is easy to operate.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. 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. Such 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.
