Description

Technical Field

[0001] This invention relates to the field of rail transportation technology, and in particular to a multi-layer automatic roller beam device and its long rail transport vehicle group. Background Technology

[0002] Existing multi-layer automatic roller beam devices and their long rail transport assemblies use roller beams fixed to the transport assemblies to reduce frictional resistance during rail loading and unloading. In multi-layer rail transport, the roller beams play a primary load-bearing role, and the rails are fixed together using the same device for the entire layer. The fixing force of the rails mainly relies on the frictional force generated by the pressure of the upper layer. Most existing solutions use rollers as the main load-bearing device, which significantly impacts roller lifespan. Rollers are mostly straight cylinders, and some rollers have vertical flanges at both ends, with no upper limit on the rails, making them prone to lateral slippage or collapse. In current devices, the roller beam is fixed by the pressure of the upper pressure plate, which poses a significant risk of lateral rail slippage. After the rails are fixed in the existing solution, the pressure between the rails and the roller beam is difficult to adjust according to road conditions, making it easy for the rails to collide with the roller beam. The roller beam assembly is driven by gears, with the central column essentially suspended in the air. When the transported rails move up and down, both the gears and the central column are at risk of failure.

[0003] Therefore, how to improve the working efficiency and safety of transport rails is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-layer automatic roller beam device that can improve the efficiency and safety of transporting steel rails. Another purpose of this invention is to provide a long rail transport vehicle assembly including the above-mentioned multi-layer automatic roller beam device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0009] The second column is arranged along the first direction and located on both sides of the first column in the second direction. The end of the roller frame is away from the first column, and its end is mounted on the second column.

[0010] The third column is arranged along the first direction and is located on one side of the first column along the third direction;

[0011] A drive column is provided along the first direction and located on the side of the first column opposite to the third direction. The drive column is provided with a drive assembly for providing the power required for the rotation of the roller beam assembly.

[0012] A locking assembly is provided on the second column and the third column for engaging with the roller frame;

[0013] The first direction, the second direction, and the third direction are perpendicular to each other.

[0014] Preferably, a plurality of rollers are arranged inside the roller frame along the length of the roller frame, and the axes of the rollers are all located on the same straight line. The rollers are fixed inside the roller frame by pressure strips.

[0015] Preferably, the roller comprises:

[0016] The roller shaft has cuboid structures at both ends to prevent the roller from rotating within the roller frame;

[0018] Preferably, the roller frame is connected to the first column via a hinge.

[0019] Preferably, the roller frame is provided with a limiting component for restricting the movement of the rail. The limiting component includes: a rotating mechanism, a transmission rod, a gear, and a limiting plate. The rotating mechanism is located at the end of the roller frame away from the first column. The transmission rod is arranged along the length direction of the roller frame and connected to the rotating mechanism. The gear is located on the transmission rod. The limiting plate is provided with a rack that cooperates with the gear. The limiting plate is located between the roller frame and the transmission rod and can cooperate with the gear to move along the first direction.

[0020] Preferably, a bending plate is provided between the third column and the first column, and the bending plate is provided at the ends of the third column and the first column along the first direction. The bending plate is also provided between the driving column and the first column, and the bending plate is provided at the ends of the driving column and the first column along the first direction.

[0021] Preferably, the driving component includes:

[0022] The first mounting base is fixedly installed on the drive column;

[0023] The second mounting base is fixedly installed on the roller frame;

[0024] The drive mechanism, connected between the first mounting base and the second mounting base via a pin, is used to provide power for the rotation of the roller frame.

[0025] Preferably, the connection points between the drive mechanism and the first mounting base, and between the drive mechanism and the second mounting base, are provided with flat washers and bushings.

[0026] Preferably, the locking assembly includes a pushing mechanism and a locking tongue. The pushing mechanism is located inside the second column and the third column, and its movable end moves along the first direction. The locking tongue is located at the movable end of the pushing mechanism and can be used to lock the roller frame to prevent it from rotating.

[0027] The present invention also provides a long rail transport vehicle group, including any of the above-mentioned multi-layer automatic roller beam device.

[0028] Compared to the aforementioned background technology, the present invention provides a multi-layer automatic roller beam device, comprising: a first column, arranged along a first direction; at least one set of roller beam assemblies, each roller beam assembly including a roller frame and a roller, the roller frame being rotatably connected to the first column and having its rotation axis aligned with the first direction, the roller being disposed within the roller frame and having its axis of rotation aligned with the length extension direction of the roller frame, the at least one set of roller beam assemblies being sequentially arranged on the first column along the first direction; a second column, arranged along the first direction and located on both sides of the first column in a second direction, the roller frame having an end facing away from the first column, and its end being mounted on the second column; a third column, arranged along the first direction and located on one side of the first column along a third direction; a drive column, arranged along the first direction and located on the side of the first column facing away from the third direction, the drive column being provided with a drive assembly for providing the power required for the rotation of the roller beam assembly; and a locking assembly disposed on the second column and the third column for engaging with the roller frame; the first direction, the second direction, and the third direction are perpendicular to each other.

[0029] Specifically, the first column is fixedly installed along a first direction, and at least one set of roller beam assemblies is installed on the first column. The roller beam assemblies can rotate around the first column, and the rotation direction is perpendicular to the first direction. The roller frame in the roller beam assembly is provided with a roller, and the axis of the roller is consistent with the length direction of the roller frame. Second columns are provided on both sides of the first column along a second direction, and a third column is provided on one side of the first column along a third direction. The second and third columns are for supporting the roller beam assemblies. The drive column is located on the side of the first column away from the third direction. The drive column is provided with a drive assembly, and the drive assembly is connected to the roller beam assembly to provide power for the rotation of the roller beam assembly. In addition, locking assemblies for locking the roller beam assemblies are also provided on the second and third columns.

[0030] In other words, when installing rails, the bottommost roller beam assembly is installed first. The upper roller beam assembly is rotated from the second column to the third column and locked. The rails are then hoisted to the roller beam assembly using hoisting equipment, and a winch is used to drag the rails while the rollers rotate. This reduces friction during rail movement and increases transport efficiency. After one layer is completed, the uppermost roller beam assembly fixed to the third column is rotated to the second column using a drive assembly and locked using a locking assembly. The rail hoisting process is then repeated. When removing rails, the process is reversed. The rails are first removed from the topmost roller beam assembly. The roller beam assembly with the removed rails is then unlocked from the locking assembly at the second column, rotated to the third column using a drive assembly, and locked. Finally, the rails on the top roller beam assembly are removed.

[0031] In this way, the roller beams are arranged in multiple layers, which can increase transportation efficiency. Each layer of the roller beams can be opened and locked individually. The multi-layer automatic roller beams are automatically controlled, reducing the inconvenience of manual operation and lowering the safety risks of manual operation. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this invention.

[0051] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, the Y direction as the second direction, and the Z direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0052] To achieve the above objectives, the present invention provides the following technical solution:

[0053] Please see Figures 1 to 6 This embodiment provides a multi-layer automatic roller beam device, including: a first column 100, at least one set of roller beam assemblies 200, a second column 400, a third column 500, a drive column 600, and a locking assembly 700; the first column 100 is arranged along a first direction; at least one set of roller beam assemblies 200, each roller beam assembly 200 including a roller frame 210 and a roller 220, the roller frame 210 being rotatably connected to the first column 100, and its rotation axis direction being consistent with the first direction, the roller 220 being disposed within the roller frame 210, and the axis direction of the roller 220 being the length extension direction of the roller frame 210, and at least one set of roller beam assemblies 200 being sequentially arranged on the first column 100 along the first direction; the second... A column 400 is arranged along the first direction and located on both sides of the first column 100 in the second direction. The end of the roller frame 210 is away from the first column 100, and its end is mounted on the second column 400. A third column 500 is arranged along the first direction and located on one side of the first column 100 along the third direction. A drive column 600 is arranged along the first direction and located on the side of the first column 100 away from the third direction. A drive assembly 610 is provided on the drive column 600 to provide the power required for the rotation of the roller beam assembly 200. A locking assembly 700 is provided on the second column 400 and the third column 500 and is used to engage with the roller frame 210. The first direction, the second direction and the third direction are perpendicular to each other.

[0054] Specifically, the first column 100 is fixedly installed along a first direction. At least one set of roller beam assemblies 200 is installed on the first column 100. Multiple sets of roller beam assemblies 200 are sequentially installed upwards from the first column 100, without interfering with each other. Simultaneously, each roller beam assembly 200 can rotate around the first column 100 in a direction perpendicular to the first direction. A roller 220 is installed inside the roller frame 210 of the roller beam assembly 200. The axis of the roller 220 is in the direction of the length extension of the roller frame 210. The roller 220 can rotate inside the roller frame 210 perpendicular to its axis. Second columns 400 are installed on both sides of the first column 100 along a second direction, and a third column 500 is installed on one side of the first column 100 along a third direction. The second columns 400 and the third column 500... All of these are designed to cooperate with the first column 100 to support the roller beam assembly 200. The second column 400 and the third column 500 are provided with notches for the roller frame 210 to pass through. This is to prevent the roller beam assembly 200 from interfering with the second column 400 and the third column 500 when rotating. The drive column 600 is located on the side of the first column 100 away from the third direction. The drive column 600 is provided with a drive assembly 610, which is rotatably connected to the roller beam assembly 200. The drive assembly 610 is mainly used to provide power for the rotation of the roller beam assembly 200. In addition, the second column 400 and the third column 500 are also provided with locking assemblies 700, which are used to lock the roller beam assembly 200 when it rotates to the second column 400 or the third column 500.

[0055] It should be noted that in this embodiment, the number of roller beam layers can be adjusted by increasing the height of the first column 100, the second column 400, the third column 500, and the drive column 600 according to actual needs. The heights of the first column 100, the second column 400, and the third column 500 are the same. In addition, to prevent excessive water accumulation inside the roller frame 210, drainage holes for drainage are provided on the front and rear sides of the roller frame 210. Furthermore, except for the first layer of roller beams, rubber shock-absorbing pads are added to the lower end of each layer of roller beam assembly, which can adjust the gap between multiple layers of roller beams and reduce vibration and noise during loading, unloading, and transportation of rails.

[0056] In other words, when it is necessary to load rails, the rails should first be loaded into the bottommost roller beam assembly 200. When loading the bottommost roller beam assembly 200, the upper roller beam assembly 200, which is fixed to the second column 400 by the locking assembly 700, is first unlocked. Then, the upper roller beam assembly 200 is rotated from the second column 400 to the third column 500 and fixed to the third column 500 by the locking assembly 700. The rails are then hoisted to the roller beam assembly 200 to be loaded using hoisting equipment, and the position of the rails is adjusted. The rails are placed on the roller 220 along the rolling direction of the roller 220, and the rails are pulled by an external winch. The rails are then moved by the rolling of the roller 220. This reduces the friction during the movement of the rails and increases the transportation efficiency. The rails are then moved to the roller beam assembly 200, which mainly bears the weight of the rails, thus completing the loading of one layer of rails.

[0057] After one layer is completed, the upper-layer roller beam assembly 200 fixed to the third column 500 is unlocked, and it is rotated to the first column 100 by the drive assembly 610 and fixed by the locking assembly 700. Then the rail hoisting steps are repeated. When it is necessary to remove the rails, the steps are reversed. First, the rails need to be removed from the uppermost roller beam assembly 200. Then, the roller beam assembly 200 with the rails removed is unlocked from the locking assembly 700 at the second column 400, rotated to the third column 500 by the drive assembly 610 and locked. Then the rails on the roller beam assembly 200 are removed until all rails are unloaded.

[0058] In this way, the roller beams are arranged in multiple layers, which can increase transportation efficiency. Each layer of the roller beams can be opened and locked individually. The multi-layer automatic roller beams are automatically controlled, reducing the inconvenience of manual operation and lowering the safety risks of manual operation.

[0059] Preferably, a plurality of rollers 220 are provided inside the roller frame 210 along the length extension direction of the roller frame 210, and the axes of the rollers 220 are all located on the same straight line. The rollers 220 are fixed inside the roller frame 210 by pressure strips 230.

[0060] Specifically, please refer to Figure 1 In this embodiment, a plurality of rollers 220 are provided inside the roller frame 210 along the length extension direction of the roller frame 210. These rollers 220 can all rotate freely. All rollers 220 are installed at the same height inside the roller frame 210. In addition, in this embodiment, pressure strips 230 are preferably used to fix the rollers 220.

[0061] Understandably, by setting multiple rollers 220 inside the roller frame 210, multiple rails can be transported simultaneously, which can greatly improve the transport efficiency of the rails and improve the utilization of the internal space of the roller frame 210.

[0062] In this embodiment, the roller 220 is fixed by the pressure strip 230. Of course, other fixing methods can also be selected according to the actual situation.

[0063] Preferably, the roller 220 includes: a roller shaft 221 and a cylindrical body 222; the roller shaft 221 has cuboid structures at both ends to prevent the roller 220 from rotating inside the roller frame 210; the cylindrical body 222 has a circular cylindrical structure, which is sleeved on the roller shaft 221, and the two ends of the cylindrical body 222 are connected to the roller shaft 221 through flanged bushings 223 and thrust washers 224.

[0064] Specifically, such as Figure 3 As shown, the roller 220 includes a roller shaft 221 and a cylindrical body 222. The cylindrical body 222 is sleeved on the roller shaft 221 and can rotate around the roller shaft 221. In this embodiment, the end of the roller shaft 221 is preferably set to a cuboid shape. Moreover, after the cylindrical body 222 and the roller shaft 221 are assembled, flanged bushings 223 and thrust washers 224 are provided at both ends. The flanged bushings 223 are located between the cylindrical body 222 and the roller shaft 221, and the thrust washers 224 are located at both ends of the cylindrical body 222. The flanged bushings 223 and the thrust washers 224 are both connected to the cylindrical body 222 and the roller shaft 221 by self-tapping screws.

[0065] Understandably, the mutual rotation between the flange bushing 223 and the roller shaft 221 can reduce the frictional resistance of the rail when it moves; the two ends of the roller shaft 221 are cuboid in shape, which can effectively prevent the roller shaft 221 from rotating when it is installed in the roller frame 210; the two ends of the roller 220 are sealed by the thrust washer 224 and screws to prevent foreign objects such as sand and stones from entering the roller 220, thereby extending the service life of the roller 220.

[0066] Preferably, the roller frame 210 is connected to the first column 100 via a hinge 211.

[0067] Specifically, in this embodiment, the roller beam is connected to the first column 100 by an asymmetric hinge 211; one side of the hinge 211 is welded to the roller frame 210, and the other side is fixed to the first column 100 by bolts, which can prevent the roller frame 210 and the limiting component 240 from interfering with the first column 100 when the roller beam rotates.

[0068] Of course, in this embodiment, the roller frame 210 is preferably connected to the first column 100 via a hinge 211, but other connection methods can be selected according to the actual situation, as long as the requirements are met.

[0069] Preferably, the roller frame 210 is provided with a limiting component 240 for restricting the movement of the rail. The limiting component 240 includes: a rotating mechanism 241, a transmission rod 242, a gear 243, and a limiting plate 244. The rotating mechanism 241 is located at the end of the roller frame 210 away from the first column 100. The transmission rod 242 is arranged along the length direction of the roller frame 210 and is connected to the rotating mechanism 241. The gear 243 is located on the transmission rod 242. The limiting plate 244 is provided with a rack that cooperates with the gear 243. The limiting plate 244 is located between the roller frame 210 and the transmission rod 242 and can cooperate with the gear 243 to move in a first direction.

[0070] Specifically, such as Figure 4 As shown, the power source of the limiting component 240 is a rotating mechanism 241. The rotating mechanism 241 is located on the end of the roller frame 210 away from the first column 100. Its output shaft faces the length direction of the roller frame 210 and is connected to the transmission rod 242. A gear 243 is provided on the transmission rod 242 at a position corresponding to the roller 220. The gear 243 can rotate with the transmission rod 242. The limiting plate 244 is specifically a square plate structure, and a rack is provided at the upper end of the limiting plate 244. The rack can mesh with the gear 243. The rotation of the rotating mechanism 241 drives the limiting plate 244 to move up and down. The transmission rod 242 is connected to the gear 243 and the rotating mechanism 241 by a key. In addition, the rotating mechanism 241 is not specifically limited in this embodiment. It can be a motor or other rotating device, as long as it meets the requirements.

[0071] Understandably, after loading the rails, the limiting plate 244 is lowered to lock the rails and prevent them from sliding arbitrarily or colliding with each other. When unloading the rails, the limiting plate 244 is raised to allow the roller beam assembly to rotate.

[0072] Preferably, a bending plate 300 is provided between the third column 500 and the first column 100, and the bending plate 300 is provided at the ends of the third column 500 and the first column 100 along the first direction. A bending plate 300 is also provided between the driving column 600 and the first column 100, and the bending plate 300 is provided at the ends of the driving column 600 and the first column 100 along the first direction.

[0073] Understandably, the third column 500 is connected to the first column 100, the drive column 600 and the first column 100 respectively by welding the bent plate 300. This arrangement can enhance the strength and rigidity of the entire fixing device.

[0074] Preferably, the drive assembly 610 includes: a first mounting base 611, a second mounting base 612, and a drive mechanism 613; the first mounting base 611 is fixedly mounted on the drive column 600; the second mounting base 612 is fixedly mounted on the roller frame 210; the drive mechanism 613 is connected between the first mounting base 611 and the second mounting base 612 by a pin, and is used to provide power for the rotation of the roller frame 210.

[0075] Specifically, such as Figure 6 and Figure 7 As shown, the drive assembly 610 is located between the roller frame 210 and the drive column 600, and is used to provide power for the rotation of the roller beam assembly 200. The power source of the drive assembly 610 is the drive mechanism 613. The drive mechanism 613 connects the roller frame 210 and the drive column 600 through the first mounting seat 611 and the second mounting seat 612. The first mounting seat 611 is fixedly mounted on the drive column 600, and the second mounting seat 612 is fixedly mounted on the roller frame 210. The drive mechanism 613 is hinged to the first mounting seat 611 and the second mounting seat 612 respectively. The drive mechanism 613 is connected to the first mounting seat 611 and the second mounting seat 612 through a pin. The drive mechanism 613 can be a hydraulic cylinder or other drive mechanism 613. This article does not make any specific limitation.

[0076] Understandably, this setup allows the roller frame 210 to be pushed and pulled by the drive mechanism 613 to open and lock the roller beam assembly 200, and the roller beam assembly 200 to be opened and closed automatically by the drive assembly 610.

[0077] Preferably, flat gaskets 614 and bushings 615 are provided at the connection points between the drive mechanism 613 and the first mounting base 611, and between the drive mechanism 613 and the second mounting base 612.

[0078] Understandably, this configuration is intended to reduce friction between the drive mechanism 613 and the first mounting base 611 and the second mounting base 612 when the drive mechanism 613 rotates, thereby extending the service life of the drive assembly 610.

[0079] Preferably, the locking assembly 700 includes a pushing mechanism 710 and a locking tongue 720. The pushing mechanism 710 is located inside the second column 400 and the third column 500, and its movable end moves in the first direction. The locking tongue 720 is located at the movable end of the pushing mechanism 710 and can be used to lock the roller frame 210 to prevent it from rotating.

[0080] Specifically, such as Figure 5As shown, in this embodiment, when the roller beam assembly 200 rotates to the second column 400 or the third column 500, it is fixed by the locking assembly 700. The power source of the locking assembly 700 is the pushing mechanism 710. The movable end of the pushing mechanism 710 is provided with a locking tongue 720. The locking tongue 720 can move up and down with the movement of the pushing mechanism 710. The end of the roller frame 210 is provided with a through hole that engages with the locking tongue 720. When the roller frame 210 rotates to the locking assembly 700, the pushing mechanism 710 will push the locking tongue 720 downward, so that the locking tongue 720 is inserted into the locking hole at the end of the roller frame 210. In this embodiment, a multi-layer roller beam assembly 200 is provided. Therefore, multiple sets of locking assemblies 700 are also provided.

[0081] Furthermore, the present invention provides a long rail transport vehicle group, including the multi-layer automatic roller beam device described above.

[0082] In summary, this invention provides a multi-layer automatic roller beam device, comprising: a first column 100, at least one set of roller beam assemblies 200, a second column 400, a third column 500, a drive column 600, and a locking assembly 700; the roller beam assemblies 200 are all mounted on the first column 100, and the roller beam assemblies 200 can rotate automatically under the action of the drive assembly 610 on the drive column 600, and can be fixed by the locking assembly 700 when transporting steel rails, through the cooperation of the multi-layer roller beam assemblies 200 and other components. The roller beam assembly 200 can work together to move, fix, and load / unload the rails. The roller beam assembly 200 is arranged in multiple layers, and each layer can be opened and locked individually, which can improve transportation efficiency. To facilitate the fixing and limiting of the rails during transportation, the roller beam assembly 200 is also equipped with a limiting component 240.
