[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0036] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components.

[0037] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.
[0038] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.
[0039] See also Figure 1 , an embodiment of the present application provides a rail flatbed limiting device 1, comprising a base 11, a first adjusting member 12 and a second adjusting member 13. The base 11 is fixedly arranged on the edge of the rail flatbed, the first adjusting member 12 is detachably connected to the base 11, and the side surface of the first adjusting member 12 forms a first limiting surface 121. The second adjusting member 13 is detachably connected to the first adjusting member 12, and the side surface of the second adjusting member 13 forms a second limiting surface 131, and the orientation of the first limiting surface 121 and the orientation of the second limiting surface 131 are both parallel to the horizontal direction. Wherein, the second adjusting member 13 is configured to be able to switch between a first position and a second position, and when the second adjusting member 13 is in the second position, it is located above the second adjusting member 13 when it is in the first position.
[0040] In the embodiment of the present application, a railroad flatbed limiting device 1 may be provided on both sides of the railroad flatbed, thereby limiting the rails placed on the railroad flatbed via the first limiting surface 121 and the second limiting surface 131 on both sides. It is understandable that only one railroad flatbed limiting device 1 may be provided on the same side of the railroad flatbed, or multiple railroad flatbed limiting devices 1 may be provided, which is not limited herein.
[0041] During the installation of the rail trolley limiting device 1 , the base 11 is first installed on the rail trolley, then the first adjusting member 12 is installed on the base 11 , and finally the second adjusting member 13 is installed on the first adjusting member 12 .
[0042] The second adjusting member 13 can be adjusted according to the height of the rails placed on the rail flatbed. For example, the second adjusting member 13 can be switched between a first position and a second position, wherein the height of the second adjusting member 13 when in the second position is higher than the height of the second adjusting member 13 when in the first position. When the height of the rails placed on the rail flatbed is relatively low, the second adjusting member 13 can be in the first position to achieve a position limiting effect; when the height of the rails placed on the rail flatbed is relatively high, the second adjusting member 13 can be switched to the second position to achieve a position limiting effect.
[0043] In the embodiment of the present application, the second adjustment member 13 can be switched between the first position and the second position, so that the second adjustment member 13 can be adaptively adjusted according to the height of the stacked rails on the rail flatbed, thereby increasing the limit height of the rail flatbed limit device 1.
[0044] Please also refer to Figure 1 and Figure 2 In some embodiments, the first adjusting member 12 is provided with a first accommodating cavity 122 , and the lower end of the second adjusting member 13 is accommodated in the first accommodating cavity 122 .
[0045] The depth direction of the first accommodating cavity 122 may be substantially parallel to the vertical direction.
[0046] The lower end of the second adjusting member 13 is accommodated in the first accommodating cavity 122 of the first adjusting member 12, forming a nested connection structure, which helps to increase the overall stability of the rail platform vehicle limiting device 1. In addition, when installing the second adjusting member 13, it is only necessary to align the lower end of the second adjusting member 13 with the first accommodating cavity 122 and insert it, which reduces the difficulty of installing the second adjusting member 13.
[0047] In some other embodiments, the second adjusting member 13 and the first adjusting member 12 may also be arranged to overlap in the horizontal direction.
[0048] Please refer again Figure 1 In some embodiments, the inner wall of the first accommodating cavity 122 formed by the first adjusting member 12 is provided with a first through hole 123 and a second through hole 124, and the first through hole 123 and the second through hole 124 are distributed in the vertical direction. The railroad flatbed vehicle limiting device 1 also includes a fixing member 14 connected to the second adjusting member. The fixing member 14 selectively cooperates with the first through hole 123 or the second through hole 124. When the fixing member 14 cooperates with the first through hole 123, the second adjusting member 13 is in the first position, and when the fixing member 14 cooperates with the second through hole 124, the second adjusting member is in the second position.
[0049] The first through hole 123 and the second through hole 124 communicate with the first accommodating cavity 122 and pass through the first adjusting member 12. The first through hole 123 and the second through hole 124 can be substantially disposed above the first adjusting member 12 to prevent interference between the fixing member 14 and the base 11.
[0050] The second adjusting member 13 may be provided with a mating hole for connecting with the fixing member 14, and the mating hole may selectively face the first through hole 123 or the second through hole 124. For example, when the second adjusting member 13 needs to be switched to the first position, the second adjusting member 13 is adjusted so that the mating hole faces the first through hole 123, and the fixing member 14 is inserted through the first through hole 123 and the mating hole, thereby stably maintaining the second adjusting member 13 in the first position. When the second adjusting member 13 needs to be switched to the second position, the second adjusting member 13 is adjusted so that the mating hole faces the second through hole 124, and the fixing member 14 is inserted through the second through hole 124 and the mating hole, thereby stably maintaining the second adjusting member 13 in the second position.
[0051] The first through hole 123 , the second through hole 124 and the matching hole may all be screw holes, the fixing member 14 may be a bolt, and the fixing member 14 may be threadedly matched with the first through hole 123 , the second through hole 124 and the matching hole.
[0052] In some other embodiments, the second through hole 124 may be located above the first through hole 123 in the vertical direction, and the first through hole 123 and the second through hole 124 may be staggered in the horizontal direction.
[0053] Please continue reading Figure 1 In some embodiments, the inner wall of the first accommodating cavity 122 formed by the first adjusting member 12 is further provided with a third through hole 125, and the third through hole 125 is located above the second through hole 124. The fixing member 14 selectively cooperates with the first through hole 123, the second through hole 124 or the third through hole 125, and when the fixing member 14 cooperates with the third through hole 125, the second adjusting member 13 switches to the third position, and when the second adjusting member 13 is in the third position, it is located above the second adjusting member 13 when it is in the second position.
[0054] Likewise, the third through hole 125 communicates with the first accommodating cavity 122 and passes through the first adjusting member 12 .
[0055] The mating hole can selectively be aligned with the first through hole 123, the second through hole 124, or the third through hole 125. For example, when the second adjustment member 13 needs to be switched to the first position, the second adjustment member 13 is adjusted so that the mating hole is aligned with the first through hole 123, and the fixing member 14 is passed through the first through hole 123 and the mating hole, so that the second adjustment member 13 can be stably positioned in the first position; when the second adjustment member 13 needs to be switched to the second position, the second adjustment member 13 is adjusted so that the mating hole is aligned with the second through hole 124, and the fixing member 14 is passed through the second through hole 124 and the mating hole, so that the second adjustment member 13 can be stably positioned in the second position; when the second adjustment member 13 needs to be switched to the third position, the second adjustment member 13 is adjusted so that the mating hole is aligned with the third through hole 125, and the fixing member 14 is passed through the third through hole 125 and the mating hole, so that the second adjustment member 13 can be stably positioned in the third position.
[0056] By providing the third through hole 125 , the second adjusting member 13 can be located in the third position, thereby further increasing the limiting height of the rail flatbed vehicle limiting device 1 .
[0057] Please refer again Figure 1 In some embodiments, a protrusion 15 is provided on the side surface of the upper end of the second adjustment member 13. The protrusion 15 has a third limiting surface 151, and the third limiting surface 151 faces downward.
[0058] The protrusion 15 protrudes horizontally from a side surface of the second adjusting member 13 .
[0059] The first limiting surface 121 and the second limiting surface 131 can limit the rails placed on the rail flatbed vehicle in the horizontal direction, and the third limiting surface 151 can limit the rails placed on the rail flatbed vehicle in the vertical direction, thereby enhancing the limiting effect on the rails placed on the rail flatbed vehicle.
[0060] In some other embodiments, the direction of the third limiting surface 151 may be inclined relative to both the vertical direction and the horizontal direction.
[0061] Please refer again Figure 1 In some embodiments, the base 11 is provided with a second accommodating cavity (not shown in the figure), and the first adjusting member 12 is partially accommodated in the second accommodating cavity.
[0062] The depth direction of the second accommodating cavity may be substantially parallel to the vertical direction.
[0063] The lower end of the first adjusting member 12 is accommodated in the first accommodating cavity 122 of the base 11, forming a nested connection structure, which helps to increase the overall stability of the rail platform vehicle limiting device 1. In addition, when installing the first adjusting member 12, it is only necessary to align the lower end of the first adjusting member 12 with the second accommodating cavity and insert it, which reduces the difficulty of installing the first adjusting member 12.
[0064] In some other embodiments, the first adjusting member 12 and the base 11 may also be arranged to overlap in the horizontal direction.
[0065] Please also refer to Figure 1 and Figure 3 In some embodiments, a fourth through hole 111 is provided on the inner wall of the second accommodating cavity formed by the base 11, and the fourth through hole 111 communicates with the second accommodating cavity. The railroad flatbed vehicle limiting device 1 further includes an elastic member 16, one end of which is connected to the first adjusting member 12, and the other end of which can at least partially extend into the fourth through hole 111 or be accommodated in the second accommodating cavity.
[0066] When installing the first adjusting member 12, the lower end of the first adjusting member 12 is aligned and inserted into the second accommodating cavity, and the end of the elastic member 16 away from the first adjusting member 12 abuts against the inner wall of the second accommodating cavity formed by the base 11. The first adjusting member 12 continues to move downward until the elastic member 16 is facing the fourth through hole 111. Under the action of the elastic force, the elastic member 16 at least partially extends into the fourth through hole 111, thereby limiting the first adjusting member 12 in the vertical direction.
[0067] In some other embodiments, the fourth through hole 111 may also be provided on the first adjusting member 12 , and the elastic member 16 may be connected to the base 11 .
[0068] Please continue reading Figure 1 and Figure 3 In some embodiments, a fourth limiting surface 161 is provided at one end of the elastic member 16 away from the first adjusting member 12 , and the fourth limiting surface 161 is used to abut against the edge of the fourth through hole 111 to limit the elastic member 16 from partially extending into the fourth through hole 111 .
[0069] By providing the fourth limiting surface 161 , the end of the elastic member 16 away from the first adjusting member 12 can be limited to only partially extend into the fourth through hole 111 , which can reduce the difficulty of completely retracting the elastic member 16 into the second accommodating cavity during disassembly.
[0070] In some other embodiments, a protrusion for limiting the elastic member 16 may also be provided on the inner wall of the fourth through hole 111 .
[0071] In some embodiments, the number of the fourth through holes 111 is at least two, and the at least two fourth through holes 111 are arranged in the vertical direction.
[0072] At least two fourth through holes 111 are arranged in the vertical direction and can be further adaptively adjusted according to the height of the rails stacked on the rail flatbed vehicle, which is similar to the adjustment method of the second adjustment member 13 and will not be described here.
[0073] In some other embodiments, the number of the fourth through hole 111 may be only one.
[0074] In some embodiments, the base 11 is welded to the edge of the railcar.
[0075] Welding the base 11 to the edge of the rail flatbed can enhance the connection stability between the base 11 and the rail flatbed, and prevent the rail flatbed limiting device 1 from shaking or even falling off during transportation of the rail flatbed.
[0076] In some other embodiments, the base 11 may also be connected to the rail flatbed vehicle via a connector.
[0077] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
