Description

Technical Field

[0001] This invention relates to the field of railway transportation technology, specifically to a side-mounted mechanized railway platform and its erection method. Background Technology

[0002] Railway platform equipment is mainly used for loading and unloading support in railway transportation. It facilitates the rapid erection of temporary platforms to ensure the loading, unloading, and transportation of equipment such as vehicles, artillery, and tanks. Current technologies for platform deployment primarily involve two methods: manual assembly and mechanized erection. While manual assembly can meet the requirements of side-mounted platform setups, it significantly impacts operational speed, assembly quality, and safety, especially in scenarios where alternating loading and unloading is required on both sides of the platform, where the assembly time is even longer. Mechanized erection, while capable of supporting the side-mounted loading and unloading of flatcars, cannot meet the demands of existing three-fold platform structures, such as platform height, operation under electrified railway line power outage conditions, and ensuring that railway transportation does not exceed limits.

[0003] To address the aforementioned issues, most current mechanized platforms employ either a straight-top or angled-top erection system. This involves attaching one end of the platform to the front (or rear) of the flatcar and the other end to the ground, creating a loading and unloading passageway. However, unlike other methods, this type of mechanized platform, when used for side-mounted installations, requires the platform height to be flush with the flatcar; otherwise, it cannot accommodate vehicles boarding and alighting. Furthermore, altering the platform height inevitably increases the length of the end platform to avoid excessively steep gradients. However, this increased length makes it impossible to complete the erection and dismantling operations on electrified railway lines without power interruption when the platform is tilted, thus compromising convenience. Summary of the Invention

[0004] To address the problems in the existing technology, this invention provides a side-mounted mechanized railway platform and its erection method. The technical solution adopted by this invention to solve its technical problems is as follows: a side-mounted mechanized railway platform and its erection method, comprising a main load-bearing end platform frame and a hydraulic hoisting mechanism. Both ends of the main load-bearing end platform frame are provided with auxiliary end platform frames and extended ground-contact platform frames. A platform support leg assembly is rotatably mounted at the bottom of the main load-bearing end platform frame, and a luffing cylinder assembly is provided between the platform support leg assembly and the main load-bearing end platform frame. The secondary end platform frame and the extended ground contact platform frame are rotatably connected. Both the secondary end platform frame and the extended ground contact platform frame serve as the high end of the extended ground contact platform frame and are rotatably connected to the secondary end platform frame by installing parallel axial connecting seats. A second longitudinal deployment mechanism is provided at the connection between the secondary end platform frame and the extended ground contact platform frame. A third longitudinal deployment mechanism is provided at the connection between the secondary end platform frame and the main bearing end platform frame. The outer shells of the second and third longitudinal deployment mechanisms are rotatably connected to the secondary end platform frame. A triangular limiting lug is rotatably connected to the output end of the second longitudinal deployment mechanism. The other end of the triangular limiting lug is rotatably connected to the extended ground contact platform frame. A connecting end transmission lug is rotatably connected to the output end of the third longitudinal deployment mechanism. A first longitudinal deployment mechanism is provided at one end of the main bearing end platform frame. The outer shell of the first longitudinal deployment mechanism is rotatably connected to the main bearing end platform frame. The output end of the first longitudinal deployment mechanism is rotatably connected to the connecting end transmission lug. The outer shell of the first longitudinal deployment mechanism is rotatably connected to the main bearing end platform frame.

[0005] Preferably, a stroke controller is provided on the outside of the main bearing end platform frame. The first longitudinal unfolding mechanism, the luffing cylinder assembly, the second longitudinal unfolding mechanism, and the third longitudinal unfolding mechanism constitute a drive assembly for platform extension. The drive assembly is signal-connected to the stroke controller, and the stroke controller sets the active stroke when the main bearing end platform frame, the auxiliary end platform frame, and the extended ground contact platform frame are unfolded or folded.

[0006] Preferably, the connecting end transmission lug is located between the main bearing end platform frame and the auxiliary end platform frame, and both the main bearing end platform frame and the auxiliary end platform frame are rotatably connected to the connecting end transmission lug.

[0007] Preferably, an axial transmission seat is provided at the bottom of the main load-bearing end platform frame, one end of the platform support leg assembly is rotatably connected to the axial transmission seat, the output end of the luffing cylinder assembly is rotatably connected to the platform support leg assembly, and a support angle connecting pin is also provided between the main load-bearing end platform frame and the platform support leg assembly. The support angle connecting pin is used to limit the deployment path of the platform support leg assembly.

[0008] Preferably, the main bearing end platform frame, the secondary end platform frame, and the extended ground contact platform frame are all fixedly connected to one side with a horizontally widened platform plate, and the gap between the main bearing end platform frame, the secondary end platform frame, and the extended ground contact platform frame after being unfolded is less than 30cm and greater than 10cm.

[0009] Preferably, a hydraulic hoisting mechanism is detachably connected to one end of the main bearing end platform frame. The hydraulic hoisting mechanism is installed on a loading and transport vehicle and is used to lift the main bearing end platform frame, the secondary end platform frame, and the extended ground contact platform frame to the lateral railway pavement.

[0010] Preferably, one end of the extended ground contact platform is rotatably connected to a bidirectional rotating shaft seat, and the other end of the bidirectional rotating shaft seat is rotatably connected to the triangular limiting lug.

[0011] Preferably, a middle support platform is provided at the bottom of the horizontally widened station slab, a telescopic crossbeam is provided between the middle support platform and the horizontally widened station slab, and a lateral reinforcing column is screwed between the station leg assembly and the horizontally widened station slab.

[0012] Preferably, a method for erecting a side-mounted mechanized railway platform includes the following steps: Step S1: The main load-bearing end platform frame is hoisted to the railway pavement by the hydraulic hoisting mechanism. Then, the stroke controller controls the output end of the luffing cylinder assembly to extend and push the top part of the platform support leg assembly, so that the platform support leg assembly rotates along the shaft connection of the axial transmission seat until the platform support leg assembly is in a vertical state and is flush with the loading surface of the loading and transport vehicle. Then, proceed to the next erection step. Step S2: The stroke controller controls the output end of the first longitudinal deployment mechanism to retract, so that the connecting end transmission lug is pulled by the first longitudinal deployment mechanism to drive the auxiliary end platform frame and the extended ground contact platform frame to rotate into a vertical state, and then proceed to the next erection step. Step S3: The stroke controller controls the output end of the third longitudinal unfolding mechanism to retract, changing the rotation angle of the auxiliary end platform frame, so that the overall erection surface of the auxiliary end platform frame tilts upward, leaving a pre-reserved flipping distance between the extended ground contact platform frame and the loading surface when the extended ground contact platform frame touches the ground. After the tilting adjustment of the auxiliary end platform frame is completed, the flipping path of the extended ground contact platform frame is no longer restricted, and then the next erection step can be carried out. Step S4: The stroke controller controls the output end of the second longitudinal unfolding mechanism to extend, so that the extended ground contact platform frame is rotated to the same tilt angle as the auxiliary platform frame through the bidirectional rotation limit of the triangular limit bracket and the parallel axial connecting seat, so that the main bearing end platform frame, the auxiliary end platform frame and the extended ground contact platform frame are fully unfolded, and then the next erection step can be carried out. Step S5: The stroke controller controls the output end of the third longitudinal unfolding mechanism to retract, causing the secondary end platform frame and the extended ground contact platform frame to move towards the loading surface of the loading vehicle. When the grounding end of the extended ground contact platform frame rotates to the lowest point, the side of the secondary end platform frame near the main bearing end platform frame is supported by the connecting end transmission lug. The hydraulic hoisting mechanism lowers the main bearing end platform frame to the railway pavement, so that the extended ground contact platform frame and the platform support leg assembly touch the ground and are supported. A mechanical platform is formed by the transversely widened platform plate set between the main bearing end platform frame, the secondary end platform frame, and the extended ground contact platform frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: a multi-directional folding platform is formed by progressively unfolding the main bearing end platform frame, the secondary end platform frame, and the extended ground contact platform frame. During the erection process, the output end of the third longitudinal unfolding mechanism is controlled by the stroke controller to retract and change the rotation angle of the secondary end platform frame, so that the overall erection surface of the secondary end platform frame tilts upward. A rotation gap is reserved between the extended ground contact platform frame and the loading surface when the extended ground contact platform frame is grounded, so that after the secondary end platform frame completes the tilt adjustment, the rotation path of the extended ground contact platform frame will not be restricted. This erection method will not cause movement interference to the track during laying, ensuring that the erection and dismantling operations can be completed under the condition of no power outage on the electrified railway line, and solving the problem of exceeding the railway transport limit of the platform.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 10 As shown, the side-mounted mechanized railway platform of the present invention includes a main load-bearing end platform frame 1 and a hydraulic hoisting mechanism 6. Both ends of the main load-bearing end platform frame 1 are provided with a secondary end platform frame 2 and an extended ground contact platform frame 3. A platform support leg assembly 4 is rotatably provided at the bottom of the main load-bearing end platform frame 1. A luffing cylinder assembly 41 is provided between the platform support leg assembly 4 and the main load-bearing end platform frame 1.

[0028] The secondary end platform frame 2 and the extended ground contact platform frame 3 are rotatably connected. Both the secondary end platform frame 2 and the extended ground contact platform frame 3 serve as the high end of the extended ground contact platform frame 3 and are rotatably connected to the secondary end platform frame 2 by installing a parallel axial connecting seat 32.

[0029] A second longitudinal deployment mechanism 21 is provided at the connection between the secondary end platform frame 2 and the extended ground contact platform frame 3. A third longitudinal deployment mechanism 22 is provided at the connection between the secondary end platform frame 2 and the main bearing end platform frame 1. The outer shells of both the second and third longitudinal deployment mechanisms 21 and 22 are rotatably connected to the secondary end platform frame 2. A triangular limiting lug 31 is rotatably connected to the output end of the second longitudinal deployment mechanism 21, and the other end of the triangular limiting lug 31 is rotatably connected to the extended ground contact platform frame 3. A connecting end transmission lug 12 is rotatably connected to the output end of the third longitudinal deployment mechanism 22. A first longitudinal deployment mechanism 11 is provided at one end of the main bearing end platform frame 1. The outer shell of the first longitudinal deployment mechanism 11 is rotatably connected to the main bearing end platform frame 1. The output end of the first longitudinal deployment mechanism 11 is rotatably connected to the connecting end transmission lug 12. The outer shell of the first longitudinal deployment mechanism 11 is rotatably connected to the main bearing end platform frame 1. In this embodiment, two sets of main bearing end platform frame 1, secondary end platform frame 2, and extended ground contact platform frame 3 are provided. A transversely widened platform plate 7 is installed between each two sets of main bearing end platform frame 1, secondary end platform frame 2, and extended ground contact platform frame 3 for widening. The main bearing end platform frame 1, secondary end platform frame 2, and extended ground contact platform frame 3 are gradually unfolded to form a multi-directional folding platform. Furthermore, the gradual unfolding method can be used to complete the erection and dismantling operations on electrified railway lines without power interruption, effectively solving the problem of exceeding the railway transport limit of the platform.

[0030] In one optional embodiment of this example, a stroke controller 5 is provided on the outside of the main bearing end platform frame 1. The first longitudinal unfolding mechanism 11, the luffing cylinder assembly 41, the second longitudinal unfolding mechanism 21, and the third longitudinal unfolding mechanism 22 constitute a drive assembly for platform extension. The drive assembly is signal-connected to the stroke controller 5, and the stroke controller 5 sets the active stroke when the main bearing end platform frame 1, the auxiliary end platform frame 2, and the extended ground contact platform frame 3 are unfolded or folded.

[0031] In one optional embodiment of this example, the stroke controller 5 is used to set the directional extension and retraction distance of the first longitudinal deployment mechanism 11, the luffing cylinder assembly 41, the second longitudinal deployment mechanism 21, and the third longitudinal deployment mechanism 22, so that the main bearing end platform 1, the auxiliary end platform 2, and the extended ground contact platform 3 can move along a fixed trajectory during folding or extending adjustments. In one optional embodiment of this example, the connecting end transmission lug 12 is located between the main bearing end platform frame 1 and the auxiliary end platform frame 2, and both the main bearing end platform frame 1 and the auxiliary end platform frame 2 are rotatably connected to the connecting end transmission lug 12.

[0032] In this embodiment, the connecting end transmission lug 12 is provided to limit the rotation path of the secondary end platform frame 2 during its adjustment, and at the same time, it is used to provide lateral support to the secondary end platform frame 2 when the main bearing end platform frame 1, the secondary end platform frame 2, and the extended ground contact platform frame 3 are erected, so as to maintain the stability of the secondary end platform frame 2 when it is used as a platform to guide passengers off the train.

[0033] In one optional embodiment of this example, an axial transmission seat 43 is provided at the bottom of the main bearing end platform frame 1, one end of the platform leg assembly 4 is rotatably connected to the axial transmission seat 43, the output end of the luffing cylinder assembly 41 is rotatably connected to the platform leg assembly 4, and a support angle connecting pin 42 is also provided between the main bearing end platform frame 1 and the platform leg assembly 4. The support angle connecting pin 42 is used to limit the unfolding path of the platform leg assembly 4.

[0034] In this embodiment, the axial transmission seat 43 is used to set the rotation axis of the platform support leg assembly 4, so that when the platform support leg assembly 4 rotates, it moves stably along the axis of the axial transmission seat 43 to a vertical ground contact state, keeping the main bearing end platform frame 1, the ground contact surface of the platform support leg assembly 4, and the ground at the erection site in a parallel support state. At the same time, after the platform support leg assembly 4 is in a vertical state, the support angle connecting pin 42 rotates in the same direction as the platform support leg assembly 4. The support force applied in the same direction after the output end of the luffing cylinder assembly 41 and the support angle connecting pin 42 press the platform support leg assembly 4 against it maintains the stability of the platform support leg assembly 4.

[0035] In one optional embodiment of this invention, a horizontally widened platform plate 7 is fixedly connected to one side of the main load-bearing platform 1, the secondary platform 2, and the extended ground-contact platform 3. After unfolding, the gap between the main load-bearing platform 1, the secondary platform 2, and the extended ground-contact platform 3 is less than 30cm and greater than 10cm. Please refer to the accompanying drawings in the specification. Figure 10 Two main load-bearing end platform frames 1, two auxiliary end platform frames 2, and two extended ground contact platform frames 3 are set as a group of platform frames. The two groups of platform frames are connected by two horizontally adjacent main load-bearing end platform frames 1, auxiliary end platform frames 2, and extended ground contact platform frames 3 to fix the horizontally widened station plate 7 to form a mechanized platform. In this embodiment, the gap formed between the main bearing end platform 1, the secondary end platform 2 and the extended ground contact platform 3 is used to maintain the movement space between the main bearing end platform 1, the secondary end platform 2 and the extended ground contact platform 3 when rotating, folding or unfolding, to avoid movement interference, and to further reserve space for electrical equipment lines during installation.

[0036] In one optional embodiment of this example, a hydraulic hoisting mechanism 6 is detachably connected to one end of the main bearing end platform 1. The hydraulic hoisting mechanism 6 is installed on a loading and transport vehicle and is used to lift the main bearing end platform 1, the secondary end platform 2, and the extended ground contact platform 3 to the lateral railway pavement.

[0037] In this embodiment, the hydraulic hoisting mechanism 6 is only used to hoist the main bearing end platform 1, the secondary end platform 2 and the extended ground contact platform 3 to the erection position after connecting the hoisting fixture. Its hoisting method is not an improvement of this invention, so its specific hoisting principle will not be described in detail in this embodiment.

[0038] In one optional embodiment of this example, one end of the extended ground contact platform 3 is rotatably connected to a bidirectional rotating shaft seat 33, and the other end of the bidirectional rotating shaft seat 33 is rotatably connected to a triangular limiting support 31.

[0039] The triangular limiting lug 31 serves as a three-axis connection end, connected to the main bearing end platform frame 1, the second longitudinal unfolding mechanism 21, and the bidirectional rotating shaft seat 33 via rotating shafts. This is used to keep the extended ground contact platform frame 3 and the secondary end platform frame 2 rotating and retracting along a fixed arrangement path, ensuring that the secondary end platform frame 2 and the extended ground contact platform frame 3 are rotated to a predetermined angle after erection to complete the construction. At the same time, it serves to support the extended ground contact platform frame 3 and the secondary end platform frame 2 after erection.

[0040] In one optional embodiment of this example, a middle support platform 8 is provided at the bottom of the horizontally widened station plate 7, and a telescopic crossbeam 81 is provided between the middle support platform 8 and the horizontally widened station plate 7. A lateral reinforcing column 71 is screwed between the station leg assembly 4 and the horizontally widened station plate 7.

[0041] In this embodiment, the telescopic beam 81 serves to provide lateral support after the main load-bearing platform frame 1, the secondary platform frame 2, and the extended ground contact platform frame 3 are erected. The lateral reinforcing column 71 provides triangular support between the platform leg assembly 4 and the main load-bearing platform frame 1, thereby increasing the support performance of the main load-bearing platform frame 1, the secondary platform frame 2, the extended ground contact platform frame 3, and the laterally widened platform 7 after erection. This ensures that the guide path of the laterally widened platform 7 set on the main load-bearing platform frame 1, the secondary platform frame 2, and the extended ground contact platform frame 3 remains stable when subjected to a large range of passing pressure. The telescopic beam 81 is bolted to the laterally widened platform 7 and the intermediate support platform 8, and the lateral reinforcing column 71 is bolted to the platform leg assembly 4 and the laterally widened platform 7. Assembly is only started after the erection is completed.

[0042] To ensure that the installation of this invention does not interfere with the track laying process and that the installation and dismantling operations can be completed on electrified railway lines without power interruption, this embodiment proposes a method for installing a side-mounted mechanized railway platform, comprising the following steps: Step S1: The main bearing end platform frame 1 is hoisted to the railway pavement by the hydraulic hoisting mechanism 6. Then, the stroke controller 5 controls the output end of the luffing cylinder assembly 41 to extend and push the top part of the platform support leg assembly 4, so that the platform support leg assembly 4 rotates along the shaft connection of the axial transmission seat 43 until the platform support leg assembly 4 is in a vertical state and is flush with the loading surface of the loading and transport vehicle. Then, the next erection step is carried out. Step S2: The stroke controller 5 controls the output end of the first longitudinal deployment mechanism 11 to retract, so that the connecting end transmission lug 12 is pulled by the first longitudinal deployment mechanism 11 to drive the auxiliary end platform frame 2 and the extended ground contact platform frame 3 to rotate into a vertical state, and then proceed to the next erection step. Step S3: The stroke controller 5 controls the output end of the third longitudinal unfolding mechanism 22 to retract, changing the rotation angle of the auxiliary end platform 2, so that the overall erection surface of the auxiliary end platform 2 tilts upward, leaving a pre-reserved flipping distance between the extended ground contact platform 3 and the loading surface when the extended ground contact platform 3 touches the ground. After the tilting adjustment of the auxiliary end platform 2 is completed, the flipping path of the extended ground contact platform 3 is no longer restricted, and then the next erection step can be carried out. Step S4: The stroke controller 5 controls the output end of the second longitudinal unfolding mechanism 21 to extend, so that the extended ground contact platform 3 is rotated to the same tilt angle as the auxiliary end platform 2 through the bidirectional rotation limit of the triangular limit support 31 and the parallel axial connecting seat 32, so that the main bearing end platform 1, the auxiliary end platform 2 and the extended ground contact platform 3 are fully unfolded, and then the next erection step can be carried out. Step S5: The stroke controller 5 controls the output end of the third longitudinal unfolding mechanism 22 to retract, causing the secondary end platform frame 2 and the extended ground contact platform frame 3 to move towards the loading surface of the loading vehicle until the grounding end of the extended ground contact platform frame 3 rotates to the lowest point. The side of the secondary end platform frame 2 closest to the main bearing end platform frame 1 is supported by the connecting end transmission lug 12. The hydraulic hoisting mechanism 6 lowers the main bearing end platform frame 1 to the railway pavement, so that the extended ground contact platform frame 3 and the platform support leg assembly 4 touch the ground and are supported. A mechanical platform is formed by the transversely widened platform plate 7 set between the main bearing end platform frame 1, the secondary end platform frame 2, and the extended ground contact platform frame 3.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.

Step S4: The stroke controller (5) controls the output end of the second longitudinal unfolding mechanism (21) to extend, so that the extended ground contact platform (3) is rotated to the same tilt angle as the auxiliary end platform (2) through the bidirectional rotation limit of the triangular limit bracket (31) and the parallel axial connecting seat (32), so that the main bearing end platform (1), the auxiliary end platform (2) and the extended ground contact platform (3) are fully unfolded, and then the next erection step can be carried out. Step S5: The output end of the third longitudinal unfolding mechanism (22) is controlled by the stroke controller (5) to retract, so that the auxiliary end platform frame (2) and the extended ground contact platform frame (3) are displaced toward the loading surface of the loading vehicle until the ground end of the extended ground contact platform frame (3) rotates to the lowest point. The side of the auxiliary end platform frame (2) close to the main bearing end platform frame (1) is supported by the connecting end transmission lug (12). The main bearing end platform frame (1) is lowered to the railway pavement by the hydraulic hoisting mechanism (6), so that the extended ground contact platform frame (3) and the platform support leg assembly (4) touch the ground and are supported. A mechanical platform is formed by the transversely widened station plate (7) set between the main bearing end platform frame (1), the auxiliary end platform frame (2), and the extended ground contact platform frame (3).
