Description

Technical Field

[0001] This invention belongs to the field of transportation technology, and more specifically, relates to a loading and unloading platform for railway transportation equipment. This invention also relates to a mobile equipment loading and unloading device. Background Technology

[0002] Transportation refers to the logistics activity of safely and timely transporting objects of a certain shape, mass, and volume from one location to another using specific equipment and tools. It involves the spatial displacement of goods within different geographical areas to change their spatial location. This displacement creates spatial benefits for goods, realizes their use value, and meets diverse societal needs. Transportation is one of the central links in logistics and one of the most important functions of modern logistics activities.

[0003] The carriers used in transportation generally include vehicles, ships, aircraft, pipelines, and conveyor belts. Among them, train transportation, as one of the main carriers, plays an indispensable role in the total freight volume.

[0004] Existing railway transportation typically uses freight cars to load goods, which are then transported to freight stations or railway stations by trains traveling on the tracks. However, during the transfer of goods to stations or freight stations, end platforms need to be pre-built at the stations to facilitate the transfer of goods from the cars to the platforms. However, the number of freight yards with end platforms in China is relatively limited, and the distance between the receiving location and the freight yard still requires the use of other modes of transportation, which cannot meet the need for on-demand loading of goods. Summary of the Invention

[0005] The purpose of this invention is to provide a loading and unloading platform for railway transportation equipment, which aims to solve the problem that goods cannot be loaded on trains in a timely manner when there is no end platform.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a loading and unloading platform for railway transportation equipment, comprising: A support platform is movably disposed on the upper surface of the train body along a first horizontal direction, which is perpendicular to the length direction of the train body. Two sets of transition components are respectively disposed on both sides of the support platform along the length direction of the vehicle body. The transition components are movably connected to the support platform and have a first state of being folded and stored in the support platform, and a second state of being unfolded and erected on the ground. A translation component is disposed between the support platform and the vehicle body, and is used to move the support platform along a first horizontal direction. The support platform has an overlapping state where it is stacked on top of the vehicle body, and also has an unfolded state where it is offset from the vehicle body; and A first support component is disposed on one side of the support platform along a first horizontal direction; one end of the first support component is rotatably connected to the support platform, and the other end is used to abut against the ground to form support for the support platform.

The central axis of the pivot is parallel to the first horizontal direction. There are multiple driving components, each corresponding to one of the supporting components. The driving components are installed between the support platform and the supporting components and drive the supporting components to rotate.

[0010] In one possible implementation, the support member includes: The first connecting rod has one end rotatably connected to the support platform, and the other end has an external thread. A connecting sleeve has an internal thread on its inner wall, and the internal thread at one end of the connecting sleeve mates with the external thread of the first connecting rod; and The second connecting rod has a support plate connected to one end and an external thread at the other end. The internal thread at the other end of the connecting sleeve engages with the external thread of the second connecting rod, and the external threads of the first connecting rod and the second connecting rod rotate in opposite directions.

[0011] In one possible implementation, the transition component includes: The first slab is hinged to the support platform on one side; The second ferrule is hinged to the other side of the first ferrule. Two sets of second support components are respectively disposed on both sides of the first ferrule along the first horizontal direction, and the second support components are located on the first ferrule near the part connected to the second ferrule, for supporting the unfolded first ferrule. When the transition component is in the second state, the side of the second transition plate opposite to the first transition plate overlaps the ground.

[0012] In one possible implementation, folding mechanisms are provided between the first ferrule and the support platform, and between the first ferrule and the second ferrule, the folding mechanisms comprising: A first connecting pin is disposed between the first ferrule and the support platform, or between the first ferrule and the second ferrule, and the axis of the first connecting pin is parallel to the first horizontal direction.

Detailed Implementation

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present 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 of the present invention and are not intended to limit the present invention.

[0022] Please refer to the following: Figures 1 to 4 The railway transport equipment loading and unloading platform provided by the present invention will now be described. The railway transport equipment loading and unloading platform includes: a support platform 1, two sets of transition components 2 disposed on both sides of the support platform 1, a translation component 3, and a first support component 4. The support platform 1 is movably disposed on the upper surface of the train body 5 along a first horizontal direction, perpendicular to the length direction of the train body 5. The two sets of transition components 2 are respectively disposed on both sides of the support platform 1 along the length direction of the train body 5. The translation component 3 is disposed between the support platform 1 and the train body 5, and drives the support platform 1 to move along the first horizontal direction. The support platform 1 has an overlapping state stacked on top of the train body 5, and also an unfolded state offset from the train body 5. The first support component 4 is disposed on one side of the support platform 1 along the first horizontal direction. One end of the first support component 4 is rotatably connected to the support platform 1, and the other end is used to abut against the ground to form support for the support platform 1.

[0023] Compared to existing technologies, the railway transport equipment loading and unloading platform of this invention, through the provision of a support platform 1, facilitates the carrying of the equipment to be transported. The provision of a translation component 3 allows the support platform 1 to move along a first horizontal direction. The equipment can complete loading and unloading on the support platform 1 using the support platform 1 extending out of the car body 5 and the transition component 2. Simultaneously, the provision of a first support component 4 provides support for the support platform 1 in its extended state, thereby mitigating the problem of the support platform 1 being easily damaged by the weight of large equipment over extended periods.

[0024] Specifically, the support platform 1 is welded from a frame structure composed of steel plates and structural steel to give the support platform 1 sufficient structural strength. The upper surface of the support platform 1 is made of patterned plate to give the upper surface of the support platform 1 sufficient frictional resistance.

[0025] Optionally, the transition component 2 can be configured as a driven transition plate that is hinged to the support platform 1. When the transition plate is needed, it can be manually lowered so that one end of the transition plate contacts the ground.

[0026] In some embodiments, please refer to Figure 4 and Figure 5 The translation component 3 includes a guide mechanism 31 and a drive mechanism 32. The guide mechanism 31 includes a guide wheel bracket 315, a first limiting wheel 311, a second limiting wheel 312, and a third limiting wheel 313 rotatably connected to the guide wheel bracket 315, and a guide rail 314. The guide rail 314 is fixed to the vehicle body 5. There are two sets of first limiting wheels 311. The two sets of first limiting wheels 311 roll in contact with the two sides of the guide rail 314 in the horizontal direction, and the second limiting wheels 312 and the third limiting wheels 313 roll in contact with the two sides of the guide rail 314 in the vertical direction.

[0027] The drive mechanism 32 is located between the support platform 1 and the vehicle body 5, and the drive mechanism 32 is used to drive the support platform 1 to move.

[0028] In this way, by using the drive mechanism 32 to drive the platform 1 and the guide mechanism 31 to guide the platform 1, the platform 1 can move on the car body 5 in the first horizontal direction. The second limiting wheel 312 and the third limiting wheel 313 can prevent the platform 1 from tipping over on the car body 5 due to the change in the center of gravity of the platform 1, so that the loading and unloading platform for railway transportation equipment in this embodiment is stable and reliable.

[0029] In this embodiment, the first limiting wheel 311 is used to move the support platform 1 along the first horizontal direction, and the second limiting wheel 312 and the third limiting wheel 313 are used to limit the movement of the support platform 1 in the vertical direction.

[0030] Optionally, the drive mechanism 32 can be configured as a drive motor, which is connected to each of the second limit wheels 312 via a sprocket, so that the platform 1 can always be driven by the drive motor during the movement of the vehicle body 5.

[0031] Specifically, the second limit wheel 312 is also provided in two sets. The two sets of second limit wheels 312, the two sets of first limit wheels 311 and the third limit wheel 313 are a set of limit wheels corresponding to the guide rail 314.

[0032] In some embodiments, please refer to Figures 1 to 4 The drive mechanism 32 includes a first telescopic cylinder 321, the cylinder body of which is located on the support platform 1, and the piston rod is connected to the vehicle body 5. This configuration is simple and reliable, making the movement of the support platform 1 on the vehicle body 5 more maneuverable.

[0033] Specifically, the first telescopic cylinder 321 is a hydraulic cylinder. The piston rod of the hydraulic cylinder is rotatably connected to the vehicle body 5, and the cylinder body is mounted on the support platform 1 in a hinged or fixed manner.

[0034] In some embodiments, please refer to Figure 6 The first support assembly 4 includes support members 41 and driving members 42. There are multiple support members 41 and driving members 42, with each support member 41 spaced apart on the same side of the support platform 1 along its length. One end of each support member 41 is rotatably connected to the support platform 1 via a pivot, and the other end supports the ground. The central axis of the pivot is parallel to the first horizontal direction. Each driving member 42 corresponds to one support member 41, is installed between the support platform 1 and the support member 41, and drives the support member 41 to rotate.

[0035] In the overlapped state, the support member 41 is retracted and located inside the support platform 1. In the unfolded state, the support member 41 is controlled by the drive member 42 to be perpendicular to the platform surface of the support platform 1, thereby the support member 41 forms a support for the support platform 1.

[0036] This configuration, using the support member 41 to support the support platform 1, can improve the problem of damage to the support platform 1 caused by long-term exposure to the gravity of large equipment, and can also reduce the load on the translation component 3, thereby increasing the service life of the translation component 3 and the support platform 1.

[0037] Optionally, the drive component 42 can be a telescopic cylinder, which is installed inside the side plate of the support platform 1. Its power output end is rotatably engaged with the outer peripheral surface of the support component 41. In the overlapped state, the telescopic cylinder retracts the support component 41, making it parallel to the length direction of the vehicle body 5. In the extended state, the telescopic cylinder drives the support component 41 perpendicular to the support platform 1, with one end of the support component 41 touching the ground, thus providing support for the support platform 1. Furthermore, the drive component 42, configured as a telescopic cylinder, can form a stable triangular structure together with the support component 41, making the support platform 1 more stable.

[0038] In some embodiments, please refer to Figure 12 The translation component 3 includes a third limiting wheel 313 and a first limiting wheel 311, as well as a first guide rail and a second guide rail respectively mounted on the vehicle body 5 and the first support component 4. The first support component 4 also includes a support beam 43, one end of which is rotatably engaged with the vehicle body 5, and the other end of which is rotatably engaged with the support member 41. The second guide rail is fixedly mounted on the support beam 43. During the movement of the vehicle body 5, the length direction of the support beam 43 is parallel to the length direction of the vehicle body 5. When it is necessary to move the support platform 1, the support beam 43 can be rotated in the horizontal direction so that the support beam 43 is perpendicular to the length direction of the vehicle body 5, thereby causing the support member 41 mounted on the support beam 43 to abut against the ground, forming support for the support beam 43. Furthermore, in this state, the first guide rail and the second guide rail are aligned end to end in a straight line, and the third limiting wheel 313 and the first limiting wheel 311 move sequentially along the first guide rail and the second guide rail, thereby moving to the designated position.

[0039] This configuration not only supports the unfolded platform 1, but also supports the vehicle body 5 through the support beam 43 connected to the vehicle body 5. It also facilitates the movement of the platform 1 along the first horizontal direction using the limit wheels, and the structure is stable and reliable, reducing damage to the translation component 4.

[0040] Optionally, a hydraulic cylinder for driving the support beam 43 to rotate is provided on the vehicle body, and a drive cylinder for driving the support member 41 to rotate is provided on the support beam 43.

[0041] In some embodiments, please refer to Figure 6 The support member 41 includes a first connecting rod 411, a second connecting rod 412, and a connecting sleeve 413. One end of the first connecting rod 411 is rotatably connected to the support platform 1, and the other end has an external thread. The inner wall of the connecting sleeve 413 has an internal thread, and the internal thread at one end of the connecting sleeve 413 mates with the external thread of the first connecting rod 411. One end of the second connecting rod 412 is connected to a support plate, and the other end has an external thread. The internal thread at the other end of the connecting sleeve 413 mates with the external thread of the second connecting rod 412, and the external threads of the first connecting rod 411 and the second connecting rod 412 rotate in opposite directions.

[0042] With this configuration, the distance between the first connecting rod 411 and the second connecting rod 412 can be adjusted by rotating the connecting sleeve 413. The operation is simple and the structure is stable and reliable.

[0043] Specifically, in this embodiment, the position of the first connecting rod 411 near the connecting sleeve 413 is hinged to the driving member 42 mentioned above. A through hole can be opened on the connecting sleeve 413, which is convenient for oiling and lubrication. An operating rod perpendicular to the axis of the connecting sleeve 413 can also be inserted into the through hole. The operating rod drives the connecting sleeve 413 to rotate, thereby adjusting the distance between the first connecting rod 411 and the second connecting rod 412.

[0044] Furthermore, through holes can be opened at both ends of the connecting sleeve 413. At the position where the first connecting rod 411 and the second connecting rod 412 are screwed into the connecting sleeve 413, there is a positioning groove corresponding to the through hole. After the first connecting rod 411 and the second connecting rod 412 are installed, positioning pins can be inserted into the positioning groove and the corresponding through hole to fix the position of the first connecting rod 411 and the second connecting rod 412 in the connecting sleeve 413, making the structure more stable.

[0045] In some embodiments, please refer to Figures 7 to 8 The transition assembly 2 includes a first transition plate 21, a second transition plate 22, and two sets of second support assemblies 23. One side of the first transition plate 21 is hinged to the support platform 1. The second transition plate 22 is hinged to the other side of the first transition plate 21. The two sets of second support assemblies 23 are respectively disposed on both sides of the first transition plate 21 along a first horizontal direction, and the second support assemblies 23 are located on the first transition plate 21 near the connection point with the second transition plate 22, serving to support the unfolded first transition plate 21. When the transition assembly 2 is in its second state, the side of the second transition plate 22 facing away from the first transition plate 21 rests on the ground.

[0046] This configuration, with the first transition plate 21 and the second transition plate 22 hinged together, allows for folding between them. The first transition plate 21 can also be stacked on the support platform 1 via its hinge, and thus, the first transition plate 21 and the second transition plate 22 can be stacked on the support platform 1. This places the transition component 2 in a first state of being folded and stored on the support platform 1. Furthermore, the large equipment on the support platform 1 is positioned between the folded transition components 2 on the left and right sides, preventing the large equipment from moving along the length of the support platform 1.

[0047] It should be noted that the dimensions of the first transition plate 21 and the second transition plate 22 along the first horizontal direction are smaller than the dimensions of the support platform 1, so as to facilitate the normal operation of various structures in the transition assembly 2.

[0048] In some embodiments, please refer to Figures 7 to 9Folding mechanisms 24 are provided between the first transition plate 21 and the support platform 1, and between the first transition plate 21 and the second transition plate 22. The folding mechanism 24 includes a first connecting pin 241, a connecting plate 242, a second telescopic cylinder 243, and a connecting rod 244. The first connecting pin 241 is located between the first transition plate 21 and the support platform 1, or between the first transition plate 21 and the second transition plate 22, and its axis is parallel to a first horizontal direction. The connecting plate 242 has a triangular arrangement of positioning holes 2421, a first driving hole 2422, and a second driving hole 2423 (see reference). Figure 9 The positioning hole 2421 is rotatably engaged with the first connecting pin 241. The cylinder body of the second telescopic cylinder 243 is installed inside the first transition plate 21, and the piston rod of the second telescopic cylinder 243 is rotatably engaged with the first drive hole 2422. One end of the connecting rod 244 is rotatably engaged with the second drive hole 2423, and the other end is rotatably engaged with the support platform 1 or the second transition plate 22.

[0049] In this embodiment, driven by the second telescopic cylinder 243, the connecting plate 242 rotates around the positioning hole 2421, thereby driving the transition component 2 to switch between the first state and the second state via the connecting rod 244.

[0050] This setup eliminates the need for manual operation to unfold and overlap the first and second ramps 21, saving time and effort and improving loading and unloading efficiency.

[0051] It should be noted that in this embodiment, the number of second telescopic cylinders 243 can be set to one or two. Two sets of the first connecting pin 241, connecting plate 242, and connecting rod 244 are provided, respectively located between the first transition plate 21 and the support platform 1, and between the first transition plate 21 and the second transition plate 22. When the number of second telescopic cylinders 243 is set to two, both second telescopic cylinders 243 are mounted on the first transition plate 21, and the power output ends of the two second telescopic cylinders 243 are respectively hinged to the first drive holes 2422 of the two sets of connecting plates 242. The two second telescopic cylinders 243 are simultaneously driven by external force to extend and retract, thereby driving the rotation of the two sets of connecting plates 242 to switch the transition assembly 2 between an overlapped state and an unfolded state.

[0052] Please see Figure 8 In some embodiments, when the number of second telescopic cylinders 243 is set to one, it is hinged to the connecting plates 242 located at both ends of the first cross plate 21 via a bidirectional transmission structure.

[0053] Specifically, the bidirectional transmission structure includes a first transmission shaft 245 and a second transmission shaft 246. The first transmission shaft 245 is rotatably mounted inside the first crossbar 21 with its central axis perpendicular to its length as its rotation center. There are two second transmission shafts 246, each with a first connecting position and a second connecting position located at both ends. The first connecting positions of the two second transmission shafts are hinged to both ends of the first transmission shaft, and the second connecting positions of the two second transmission shafts are hinged to the first drive holes 2422 on the corresponding connecting plates 242. The power output end of the second telescopic cylinder 243 is rotatably engaged with either the first or second connecting position. In practical applications, the number of first transmission shafts 245 and second transmission shafts 246 corresponds to the number of folding mechanisms 24.

[0054] Correspondingly, there are also two first drive shafts 245 and two second drive shafts 246, which are arranged to correspond to the connecting plate 242 in the folding mechanism 24. At the parts where the two first drive shafts 245 are connected to the second drive shafts 246 respectively, two connecting shafts pass through. One of the connecting shafts is hinged to the second telescopic cylinder 243, and the other connecting shaft has a U-shaped clearance groove to prevent the connecting shaft from affecting the movement of the second telescopic cylinder 243.

[0055] Of course, setting the two second telescopic cylinders 243 inside the support platform 1 and the first cross plate 21 respectively is also a feasible real-time method.

[0056] In some embodiments, two adjacent support platforms 1 mounted on the vehicle body 5 move in opposite directions. This arrangement takes into account the structural layout of the support platforms 1. Multiple load-bearing beams are spaced apart along a first horizontal direction inside the support platform 1. The translation component 3 mentioned above is located directly below the load-bearing beams. Correspondingly, the first support component 4 is also positioned corresponding to the load-bearing beams. Thus, due to the obstruction of the first support component 4, the support platform 1 can only move towards the side containing the first support component 4.

[0057] Of course, in this embodiment, the opposite movement directions of adjacent support platforms 1 are taken into account that when the train stops at a station or other destination, due to environmental limitations, all support platforms 1 that move on the same side may not be able to unfold, requiring a repositioning of the train. By moving adjacent support platforms 1 in opposite directions, large equipment can be unloaded using support platforms 1 located on either side of the train.

[0058] Based on the same inventive concept, please refer to Figure 1 , Figure 10 and Figure 11 The present invention also provides a mobile equipment loading and unloading device, which has the above-mentioned railway transport equipment loading and unloading platform and car body 5. A clamping component 6 is provided on the rollers of the car body 5, which is used to clamp the rollers 51 and the rails.

[0059] The mobile equipment loading and unloading device of the present invention, by setting the clamping component 6, ensures that the vehicle body 5 will not be at risk of overturning during the loading and unloading of large equipment.

[0060] Optionally, in this embodiment, please refer to Figure 1 For the structure of the vehicle body 5, its shape is "U"-shaped to lower the overall center of gravity of this embodiment.

[0061] In some embodiments, please refer to Figure 10 and Figure 11 The clamping assembly 6 includes a mounting plate 62 and a locking part 63. The mounting plate 62 has two spaced-apart abutment parts and an adjusting part. The locking part 63 is threaded to the adjusting part and is used to cooperate with the abutment parts to clamp the rollers 51 and rails 7 of the car body 5.

[0062] With this configuration, the abutment part on the mounting plate 62 and the locking part 63 connected to the adjustment part are used to move the locking part 63 by turning it, thereby shortening the gap between the abutment part and the locking part 63, and thus clamping the roller 52 and the rail 7, thereby preventing the car body 5 from overturning during the loading and unloading of large equipment.

[0063] In some embodiments, please refer to Figure 10 and Figure 11 The clamping assembly 6 also includes two limiting blocks 61, which are located on the side of the mounting plate 62 facing the rail 7 and placed at the bottom of the roller 51, for limiting the roller 51 in the front-back direction.

[0064] This configuration prevents the vehicle body 5 from shifting due to the movement of large equipment on the support platform 1 and improves the fixing effect of the clamping assembly 6 on the vehicle body 5.

[0065] Specifically, the limiting block 61 has a first contact surface that can contact the roller 51 and a second contact surface that can contact the rail 7 respectively. The shape of the first contact surface is set according to the shape of the roller 51, and the shape of the second contact surface is set according to the shape of the rail 7.

[0066] In some embodiments, the device includes multiple vehicle bodies 5 connected end-to-end, and multiple loading and unloading platforms corresponding one-to-one with the multiple vehicle bodies 5, forming a vehicle-group-type mobile equipment loading and unloading device. To mitigate the potential damage to the translation component 3 during the loading and unloading of oversized equipment on the loading platform 1, in this equipment loading and unloading device, one vehicle body 5 and its corresponding loading platform 1 are loaded with lighter goods. When loading equipment, the equipment on this loading platform 1 is loaded last. Other vehicle bodies 5 and oversized equipment on the loading platforms 1 first move to their respective loading platforms 1 via this unfolded loading platform 1, or first move to any one of the unfolded loading platforms 1 and then to their respective loading platforms 1. When unloading equipment, the equipment on this loading platform 1 is unloaded first, and large equipment on adjacent loading platforms 1 is unloaded from this loading platform 1. At this time, the loading platform 1 adjacent to the loading platform 1 to be unloaded is under zero load and can be unfolded, allowing the oversized equipment adjacent to this loading platform 1 to be unloaded from this loading platform 1. This reduces the wear and tear on the translation component 3 caused by changes in the center of gravity of the support platform 1.

[0067] Of course, in this embodiment, in order to facilitate the transfer of large equipment between different support platforms 1, small ramps are formed on both sides of the support platform 1 in the width direction (large equipment in the length direction can be transferred through the ramp) to facilitate the transition between the support platform 1 and the vehicle body 5.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
