For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be an internal connection between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0032] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts.

[0033] Next, the technical solutions of the present application will be further described in conjunction with specific embodiments and the accompanying drawings.
[0034] Please refer to Figure 1, an embodiment of the present application provides a rail fixing device 1, including a fixing member 11, a moving member 12, and a limiting member 13. The bottom of the fixing member 11 is used for detachably connecting to the rail flatbed truck. The moving member 12 is movably connected to the fixing member 11 and can switch between a first position and a second position, where the first position and the second position are arranged in the vertical direction (as shown by the Z direction in Figure 1 ), and when the moving member 12 is in the second position, it is above the moving member 12 when it is in the first position. The limiting member 13 is connected to the fixing member 11 and is used to limit the moving member 12 to be in the first position or the second position.
[0035] In this embodiment, when the rail flatbed truck needs to load and transport rail materials, the fixing member 11 can be first installed on the rail flatbed truck. After the fixing member 11 is installed, the position of the moving member 12 can be adjusted according to the quantity and stacking height of the rail materials. Exemplarily, when the height of the loaded and transported rail materials is relatively low, the moving member 12 can be switched to the first position, and the limiting member 13 is connected to the fixing member 11 and the moving member 12 to fix the moving member 12 in the first position, and at the same time, the height formed by the moving member 12 and the fixing member 11 is relatively small to match the relatively low stacked rail materials; when the height of the loaded and transported rail materials is relatively high, the moving member 12 can be switched to the second position, and the limiting member 13 is connected to the fixing member 11 and the moving member 12 to fix the moving member 12 in the second position, and at the same time, the height formed by the moving member 12 and the fixing member 11 is relatively high to match the relatively high stacked rail materials.
[0036] It should be noted that when installing the rail fixing device 1 on the rail flatbed truck, multiple rail fixing devices 1 can be installed to play a role in clamping the rail materials in the horizontal direction.
[0037] In addition, according to the quantity and stacking width of the rail materials, the position where the fixing member 11 is installed on the rail flatbed truck can be readjusted, that is, the position where the rail fixing device 1 is installed on the rail flatbed truck is readjusted.
[0038] In this embodiment, by providing the rail fixing device 1 on the rail flatbed truck, the rail materials can be fixed. In addition, according to the stacking height of the rail materials, the moving member 12 can be adjusted to be in the first position or the second position to match the stacking height of the rail materials. According to the stacking width of the rail materials, the installation position of the fixing member 11 can be readjusted to achieve the adjustment of the installation position of the rail fixing device 1.
[0039] Please refer to Figure 2 , in some embodiments, a suction cup 14 capable of adsorbing to the rail flatbed truck is provided at the bottom of the fixing member 11.
[0040] Among them, the suction cup 14 can be an electromagnetic suction cup 14 or a vacuum suction cup 14, etc., which is not limited herein.
[0041] By arranging a suction cup 14 at the bottom of the fixing member 11 to adsorb on the rail flatbed vehicle, the connection stability between the rail fixing device 1 and the rail flatbed vehicle is enhanced. At the same time, the suction cup 14 enables the fixing member 11 to quickly adsorb or disengage from the rail flatbed vehicle without using fasteners, thereby improving the installation and disassembly efficiency of the rail fixing device 1. In addition, since the connection between the suction cup 14 and the rail flatbed vehicle is achieved through adsorption force, the wear caused by friction due to the use of fasteners is reduced, and the service life of the rail fixing device 1 and the rail flatbed vehicle is prolonged.
[0042] In some other embodiments, the fixing member 11 can also be connected to the rail flatbed vehicle through fasteners.
[0043] In some embodiments, the number of the suction cups 14 is multiple, and the multiple suction cups 14 are evenly distributed at the bottom of the fixing member 11.
[0044] The even distribution of the multiple suction cups 14 can ensure more adsorption points between the fixing member 11 and the rail flatbed vehicle, thereby providing a greater adsorption force and avoiding the deviation or detachment of the rail fixing device 1 due to a smaller adsorption force.
[0045] In some other embodiments, the number of the suction cups 14 can also be one.
[0046] In some embodiments, the moving member 12 can move between a first position and a second position in the vertical direction.
[0047] The moving member 12 moves in the vertical direction, which only requires one-dimensional control, simplifies the operation process, and reduces the operation complexity. At the same time, the moving member 12 can be accurately positioned between the first position and the second position when moving in the vertical direction, so that the moving member 12 is not easily deviated during the movement.
[0048] In some other embodiments, the moving member 12 can rotate between the first position and the second position.
[0049] In some embodiments, the fixing member 11 is provided with a receiving cavity (not shown in the figure), the depth direction of the receiving cavity is parallel to the vertical direction, a part of the moving member 12 is located in the receiving cavity, and the other part protrudes from the receiving cavity, and the moving member 12 can move in the receiving cavity.
[0050] By placing a part of the moving member 12 in the receiving cavity, the inner wall of the receiving cavity surrounded by the fixing member 11 can restrict the moving member 12 in the horizontal direction, so that the moving member 12 can only move along the depth direction of the receiving cavity, that is, the moving member 12 can only move in the vertical direction.
[0051] In some other embodiments, the moving member 12 can be movably connected to the outer surface of the fixing member 11.
[0052] Please refer to Figure 1 and Figure 2 , in some embodiments, the fixing member 11 is provided with a first hole 111 and a second hole 112, the second hole 112 is located above the first hole 111, and the limiting member 13 is detachably disposed in the first hole 111 or the second hole 112 and connected to the moving member 12 to limit the moving member 12 to be in the first position or the second position.
[0053] In this embodiment, when the height of the rail material loaded and transported is relatively low, the moving member 12 can be moved to the first position, and the limiting member 13 is inserted through the first hole 111 and connected to the moving member 12 to fix the moving member 12 at the first position, so that the height formed by the moving member 12 and the fixing member 11 is relatively small to match the relatively low stacked rail material; when the height of the rail material loaded and transported is relatively high, the moving member 12 can be switched to the second position, and the limiting member 13 is inserted through the second hole 112 and connected to the moving member 12 to fix the moving member 12 at the second position, and at the same time, the height formed by the moving member 12 and the fixing member 11 is relatively high to match the relatively high stacked rail material.
[0054] In some other embodiments, the moving member 12 and the fixing member 11 can also be clamped by a buckle.
[0055] In some embodiments, the moving member 12 is provided with a third hole (not shown in the figure) and a fourth hole (not shown in the figure), and the fourth hole is located above the third hole. When the moving member 12 moves to make the third hole coaxial with the first hole 111, the limiting member 13 is inserted through the first hole 111 and the third hole to limit the moving member 12 to be in the first position; when the moving member 12 moves to make the fourth hole coaxial with the second hole 112, the limiting member 13 is inserted through the second hole 112 and the fourth hole to limit the moving member 12 to be in the second position.
[0056] In this embodiment, when the height of the rail material loaded and transported is relatively low, the moving member 12 can be moved to the first position to make the first hole 111 coaxial with the third hole, and the limiting member 13 is inserted through the first hole 111 and the third hole to fix the moving member 12 at the first position, so that the height formed by the moving member 12 and the fixing member 11 is relatively small to match the relatively low stacked rail material; when the height of the rail material loaded and transported is relatively high, the moving member 12 can be moved to the second position to make the second hole 112 coaxial with the fourth hole, and the limiting member 13 is inserted through the second hole 112 and the fourth hole to fix the moving member 12 at the second position, and at the same time, the height formed by the moving member 12 and the fixing member 11 is relatively high to match the relatively high stacked rail material.
[0057] In some other embodiments, the end of the bolt can also abut against the outer surface of the moving member 12 to fix the moving member 12 and the fixing member 11.
[0058] In some embodiments, the limiting member 13 is a bolt, and the first hole 111, the second hole 112, the third hole and the fourth hole are all provided with threads. The limiting member 13 is in threaded fit with the first hole 111 and the third hole, or the limiting member 13 is in threaded fit with the second hole 112 and the fourth hole.
[0059] In this embodiment, when the height of the rail material loaded and transported is relatively low, the moving member 12 can be moved to the first position so that the first hole 111 and the third hole are coaxial, and the bolt is in threaded fit with the first hole 111 and the third hole to fix the moving member 12 at the first position, so that the height formed by the moving member 12 and the fixing member 11 is relatively small to match the relatively low stacked rail material; when the height of the rail material loaded and transported is relatively high, the moving member 12 can be moved to the second position so that the second hole 112 and the fourth hole are coaxial, and the bolt is in threaded fit with the second hole 112 and the fourth hole to fix the moving member 12 at the second position, and at the same time, the height formed by the moving member 12 and the fixing member 11 is relatively high to match the relatively high stacked rail material.
[0060] In some other embodiments, the limiting member 13 can be a smooth rod, and the first hole 111, the second hole 112, the third hole and the fourth hole can also be smooth holes.
[0061] In some embodiments, the extending directions of the first hole 111 and the second hole 112 are both the first direction (such as Figure 1 shown by the X direction in the figure), and the first direction is perpendicular to the vertical direction.
[0062] In some other embodiments, the first direction can be inclined with respect to the vertical direction.
[0063] In some embodiments, the number of the limiting members 13, the first holes 111 and the second holes 112 is two. The two first holes 111 are spaced apart along the second direction (such as Figure 1 shown by the Y direction in the figure), the two second holes 112 are spaced apart along the second direction, and the two limiting members 13 are respectively detachably arranged in the two first holes 111 or the two second holes 112, wherein the second direction is perpendicular to the first direction and perpendicular to the vertical direction.
[0064] By respectively fixing the two limiting members 13 in the two first holes 111 or the two second holes 112, the force on a single limiting member 13 can be effectively reduced, the structural damage caused by excessive force on a single limiting member 13 can be avoided, and better stability and durability can be provided. In addition, the arrangement of the two limiting members 13 can more effectively prevent the moving member 12 from shifting or deflecting.
[0065] In some other embodiments, the number of the limiting members 13, the first holes 111 and the second holes 112 may all be three or more.
