[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0028] In order to solve the problem of complicated assembly and disassembly of the rail fixing structure 2 in the prior art, the utility model provides a rail fixing structure 2 and a moving device.

[0029] like Figures 1 to 3 As shown, the rail fixing structure 2 includes a top plate 21, a base, a rod structure and a movable clamping plate 27. The top plate 21 is used to be detachably connected to the electrical platform 3; the base is detachably connected to the top plate 21, and the base includes at least a first plate body 22 and a second plate body 23 that are arranged opposite to each other and connected to each other. The first plate body 22 and the second plate body 23 are both arranged perpendicular to the top plate 21, and the distance from the side of the second plate body 23 away from the top plate 21 to the top plate 21 is smaller than the distance from the side of the first plate body 22 away from the top plate 21 to the top plate 21; the rod structure vertically penetrates the first plate body 22 and the second plate body 23; the movable clamping plate 27 is movably arranged on the rod structure along the extension direction of the rod structure and the movable clamping plate 27 is located on the side of the second plate body 23 away from the first plate body 22, and at least the part of the movable clamping plate 27 away from the top plate 21 is spaced apart from the first plate body 22 to form a clamping space.

[0030] By providing the top plate 21, the rail fixing structure 2 can be connected to the electrical platform 3 through the top plate 21, thereby facilitating the rail fixing structure 2 to secure the electrical platform 3 to a designated position on the guide rail 1 and ensuring the reliability of the rail fixing structure 2. The first plate 22 and the second plate 23 are both arranged perpendicular to and connected to the top plate 21. The distance from the side of the second plate 23 away from the top plate 21 to the top plate 21 is less than the distance from the side of the first plate 22 away from the top plate 21 to the top plate 21. This arrangement creates a height difference between the side of the second plate 23 away from the top plate 21 and the side of the first plate 22 away from the top plate 21, thereby leaving a certain amount of space to accommodate the guide rail 1. By setting a rod structure that vertically passes through the first plate body 22 and the second plate body 23, the movable clamping plate 27 can be movably set on the rod structure and is located on the side of the second plate body 23 away from the first plate body 22. At least the part of the movable clamping plate 27 away from the top plate 21 is spaced apart from the part of the first plate body 22 that is higher than the second plate body 23 to form a clamping space. By adjusting the position of the movable clamping plate 27 on the rod structure, the size of the clamping space can be adjusted, thereby realizing the switching of the rail fixing structure 2 between the clamping state and the open state, reducing the operation difficulty, simplifying the operation process, and improving the disassembly and assembly efficiency.

[0031] Furthermore, the rail-fixing structure 2 of the present application effectively secures the electrical platform 3 to the guide rail 1, preventing displacement during operation. This prevents the electrical platform 3 from moving due to vibrations from the operating equipment, improving its stability and safety. The structure is suitable for use in industrial automated production lines, logistics delivery systems, robotic workstations, and other scenarios. Through precise clamping and fixing, the structure can adapt to various complex operating conditions, ensuring that the electrical platform 3 remains stable even during high-speed movement or under heavy loads, thereby improving production efficiency and reducing failure rates.

[0032] like Figure 2 and Figure 3 As shown, a raised portion 221 is provided on the surface of the first plate 22 facing the second plate 23. The raised portion 221 is located in the area of ​​the first plate 22 away from the top plate 21, and is spaced apart from the end of the second plate 23 away from the top plate 21. In other words, the raised portion 221 is located on the portion of the first plate 22 that is higher than the second plate 23, and is exposed when viewed from the side of the second plate 23. By spacing the raised portion 221 from the end of the second plate 23 away from the top plate 21, a certain space is reserved between the raised portion 221 and the second plate 23 for accommodating the guide rail 1. The provision of the raised portion 221 helps improve the practicality and safety of the rail fixing structure 2. Specifically, the protrusion 221 is located in the lower area of ​​the first plate 22, so that when the guide rail 1 is clamped and fixed, sufficient space can be left between the protrusion 221 and the lower end of the second plate 23 to match the width of the guide rail 1, thereby achieving a more precise and stable clamping effect.

[0033] Furthermore, the design of the raised portion 221 prevents the rail-fixing structure 2 from detaching upward from the guide rail 1 during the clamping process. When equipment operating on the electrical platform 3 generates strong vibrations, the raised portion 221 effectively abuts the side of the guide rail 1, limiting the vertical movement of the rail-fixing structure 2. This prevents vibration-induced loosening or failure of the rail-fixing structure 2, ensuring the stability and safety of the electrical platform 3 and the electrical equipment thereon, and reducing the risk of equipment damage and potential safety hazards.

[0034] In practical applications, the shape, size, and number of the protrusions 221 can be flexibly adjusted based on the specific specifications of the guide rail 1 and the load conditions of the electrical platform 3 to achieve optimal clamping. For example, the projection of the side of the protrusion 221 facing away from the first plate 22 can be semicircular, square, or trapezoidal, etc., to increase the contact area with the side of the guide rail 1 and improve friction. The thickness and height of the protrusions 221 should match the width of the guide rail 1 to ensure that excessive stress is not generated during clamping, thereby avoiding damage to the guide rail 1.

[0035] To sum up, this application not only significantly enhances the fixing ability and anti-slip ability of the rail fixing structure 2 by setting a protrusion 221 on the first plate 22, but also provides a safer and more reliable environment for the placement of electrical equipment, effectively improving the operating efficiency and operation safety of mining machinery and equipment.

[0036] like Figure 2 and Figure 3 As shown, the holder further includes a third plate 24, which is positioned between the second plate 23 and the movable clamping plate 27. The third plate 24 is fixedly connected to a surface of the second plate 23 that is away from the first plate 22. The projection of the third plate 24 on the first plate 22 is spaced apart from the raised portion 221. Specifically, the first plate 22, the second plate 23, and the third plate 24 are fixedly connected in sequence to form a single unit.

[0037] Specifically, the side surface of the second plate 23 facing the first plate 22 is a flat surface, configured to fit tightly against the plane of the first plate 22. The side surface of the second plate 23 away from the first plate 22 is a stepped surface, comprising a first surface 231, a transition surface 232, and a second surface 233, which are sequentially connected at an angle in a direction away from the top plate 21. The first surface 231 is positioned away from the first plate 22 relative to the second surface 233. In other words, the first surface 231 is higher than the second surface 233, and the first surface 231 and the second surface 233 are parallel, and both the first surface 231 and the second surface 233 are perpendicular to the transition surface 232. The third plate 24 is connected to the second surface 233 and is parallel to the second surface 233. The side surface of the third plate 24 away from the top plate 21 is flush with the side surface of the second plate 23 away from the top plate 21, and the distance from the side surface of the third plate 24 away from the first plate 22 to the first plate 22 is greater than the distance from the side surface of the protrusion 221 away from the first plate 22 to the first plate 22. This can avoid the protrusion 221 and increase the space for clamping the guide rail 1. In addition, the side surface of the third plate 24 away from the first plate 22 is flat and flush with the first surface 231, or higher than the first surface 231, or lower than the first surface 231. Figure 3 In the illustrated embodiment, a surface of the third plate 24 that is away from the first plate 22 is disposed lower than the first surface 231 .

[0038] In summary, the addition of the third plate 24 further enhances the stability of the rail-fixing structure 2 while providing additional support when clamping the guide rail 1. This makes it suitable for scenarios where the guide rail 1 bears heavy loads or the electrical platform 3 needs to move at high speeds on the guide rail 1. By adding the third plate 24, the rail-fixing structure 2 can withstand higher mechanical stresses, ensuring a secure connection between the guide rail 1 and the electrical platform 3 even when the electrical platform 3 moves at high speeds or carries heavy objects. This reduces equipment failures and production interruptions caused by unstable connections, and improves the reliability and safety of continuous operation.

[0039] like Figures 1 to 3 As shown, the rod structure includes a guide rod 28 and an adjusting screw 29. The guide rod 28 and the adjusting screw 29 have different structures. The adjusting screw 29 is located on the side of the guide rod 28 away from the top plate 21, and the line connecting the guide rod 28 and the adjusting screw 29 is arranged perpendicular to the top plate 21. The card holder has a first guide hole 25 and a first fastening hole 26. Specifically, the stacked first plate 22, second plate 23, and third plate 24 are each provided with a first guide hole 25 and a first fastening hole 26, and the three first guide holes 25 correspond to each other and the three first fastening holes 26 correspond to each other. The movable clamping plate 27 has a second guide hole 271 and a second fastening hole 272. After the movable clamping plate 27 is opened and assembled, it plays the role of clamping the guide rail 1. The first guide hole 25 corresponds to the second guide hole 271, and the first fastening hole 26 corresponds to the second fastening hole 272. The guide rod 28 is set through the three first guide holes 25 and the second guide holes 271, and the adjusting screw 29 is set through the three first fastening holes 26 and the second fastening holes 272.

[0040] In the specific embodiment of the present application, the diameter of each of the three first guide holes 25 is 28 mm. The first fastening holes 26 on the first plate 22 are threaded holes with a diameter of 24 mm. The first fastening holes 26 on the second and third plates 23 and 24 are through holes with a diameter of 28 mm. By designing the first fastening holes 26 on the first plate 22 to be smaller in size, the threaded holes can function as screw fastening holes.

[0041] like Figure 3 As shown, the guide rod 28 has a threaded section 281 and a guide section 282. Both ends of the guide rod 28 have a threaded section 281, and the guide section 282 is located between the two threaded sections 281. The threaded sections 281 at both ends of the guide rod 28 are used for assembly and fixation, while the guide section 282 serves as a guide. The diameter of both threaded sections 281 is 20 mm, and the diameter of the guide section 282 is greater than or equal to 27.2 mm and less than or equal to 28 mm. The length of the threaded section 281 on the side of the guide rod 28 closer to the first plate 22 is shorter than the length of the threaded section 281 on the side closer to the movable clamping plate 27. The length of the guide section 282 is greater than the length of the threaded sections 281 on both sides.

[0042] like Figure 3 As shown, the adjusting screw 29 includes a hexagonal structure segment 291, a first thread segment 292, a sliding segment 293, and a second thread segment 294 connected in sequence from the first side to the second side. The diameters of the first thread segment 292 and the second thread segment 294 are different. The surface of the sliding segment 293 is smooth. The hexagonal structure segment 291 is specifically a hexagonal square head. After the adjusting screw 29 is assembled on the base, the hexagonal structure segment 291 is located on the side of the first plate body 22 away from the second plate body 23. The length of the first thread segment 292 is greater than that of the other three segments. Among the hexagonal structure segment 291, the first thread segment 292, the sliding segment 293, and the second thread segment 294, the hexagonal structure segment 291 is the smallest. This arrangement enables the guide rod 28 and the adjusting screw 29 to form a stable connection with the base and the movable clamping plate 27, while also being adaptable to guide rails 1 of different widths, making it suitable for occasions where the specifications of the guide rails 1 vary.

[0043] In the specific embodiment of the present application, the hexagonal structure segment 291 is used to cooperate with a wrench to achieve a screwing action. The first threaded segment 292 has a diameter of 24 mm and is used to cooperate with the first fastening hole 26 of the first plate 22 to achieve a screw fastening effect. The sliding segment 293 has a diameter of 28 mm and cooperates with the second plate 23 and the third plate 24 to provide a guide. The second threaded segment 294 has a diameter of 20 mm and is used to cooperate with the movable clamping plate 27 for subsequent assembly and fixation.

[0044] like Figure 2 and Figure 3 As shown, the rail fixing structure 2 also includes multiple sets of fasteners, and different fasteners are respectively provided at both ends of the rod structure. The fasteners include washers and nuts 41. Specifically, the washers include elastic washers 42 and flat washers 43. Two sets of fasteners are respectively provided at both ends of the guide rod 28. One set of fasteners is located on the side of the first plate 22 away from the second plate 23, and the other set is located on the side of the movable clamp 27 away from the base. Two sets of fasteners are respectively provided at both ends of the adjusting screw 29. One set of fasteners is located on the side of the first plate 22 away from the second plate 23, and the other set is located on the side of the movable clamp 27 away from the base. The position of the movable clamp 27 is flexibly adjusted by the fasteners, and the position of the movable clamp 27 is locked and fixed at the same time. This arrangement can ensure the stability of the rail fixing structure 2. At the same time, the combination of the washers and nuts 41 can effectively prevent the threads from loosening. It is suitable for occasions with large vibrations and harsh environments, such as the installation of mining machinery and offshore wind power equipment. During the installation of mining machinery or offshore wind power equipment, the combination of the gasket and the nut 41 can effectively resist the influence of high vibration and harsh environment, prevent the loosening of the rail fixing structure 2, ensure the safety and stability of the electrical platform 3 during long-term operation, extend the service life of the equipment, and reduce the cost of maintenance and replacement.

[0045] Specifically, the movable clamping plate 27 is spaced apart from the top plate 21, which has multiple connection holes. In the specific embodiment of the present application, the top plate 21 is provided with eight connection holes with a diameter of 18 mm for connecting to the electrical platform 3. The design of multiple connection holes provides more connection options between the electrical platform 3 and the rail fixing structure 2, which is suitable for applications requiring flexible adjustment of the position of the electrical platform 3.

[0046] like Figure 1 As shown, the present application further provides a mobile device, which includes a guide rail 1, an electrical platform 3, and the aforementioned rail fixing structure 2. The electrical platform 3 has rollers 31, and the electrical platform 3 is slidably set on the guide rail 1 via the rollers 31. The rail fixing structure 2 is located between the guide rail 1 and the electrical platform 3 and is detachably connected to the electrical platform 3. The rail fixing structure 2 is used to limit the electrical platform 3 on the guide rail 1. The first plate 22 and the movable clamping plate 27 of the rail fixing structure 2 are used to clamp the guide rail 1, and the rail fixing structure 2 is switched between a clamped state and an open state by the cooperation of fasteners.

[0047] In actual use, the assembled rail fixing structure 2 is installed on the electrical platform 3. A rail fixing structure 2 can be installed on each platform about 1 meter away from the roller 31, and then the assembled electrical platform 3 is installed on the guide rail 1. When the electrical platform 3 moves, the rail fixing device is in the open state (see Figure 2 ), the electrical platform 3 can move smoothly. When the electrical platform 3 stops, use a wrench to tighten the adjusting screw 29, which tightens the movable clamping plate 27 to the side of the guide rail 1 to clamp the guide rail 1, so that the electrical platform 3 is stably fixed.

[0048] The mobile device of the present application can not only quickly fix the electrical platform 3 on the guide rail 1, but also ensure the stability and safety of the electrical platform 3 during operation, and is suitable for various industrial automation scenarios, such as automated warehouses, smart factories, high-speed logistics sorting systems, etc. By adopting the rail fixing structure 2 of the present application, the mobile device can improve the installation efficiency and use safety of the equipment while ensuring the stable operation of the electrical platform 3, reduce maintenance costs, and enhance overall production efficiency and automation level. Its advantages are particularly obvious in high-precision, high-load, and high-speed operating environments, and can significantly improve the performance and reliability of industrial automation systems.
