[0001] The utility model relates to the technical field of steel plate transportation, in particular to a steel plate seat frame and a railway transport vehicle. Background Art

[0002] When transporting steel plates by railway, due to their relatively stable shape, the steel plates are usually directly stacked in railway transport vehicles. However, the steel plates are heavy and thus have a large inertia. During the starting and stopping processes, the steel plates are likely to move relative to the transport vehicle under the action of inertia, exerting a large pressure on the inner wall of the transport vehicle. Especially at the corners of the steel plates, the inner wall of the transport vehicle is easily pushed out of pits, causing damage to the transport vehicle. Content of the Utility Model

[0003] The purpose of the utility model is to provide a steel plate seat frame, which can avoid damage to the transport vehicle caused by steel plates during transportation and has the characteristic of being convenient for storage. In addition, a railway transport vehicle including the above steel plate seat frame is provided.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] In a first aspect, the utility model provides a steel plate seat frame, including a seat frame body, a first upright post and a second upright post. The seat frame body is used for carrying steel plates. The extending directions of the first upright post and the second upright post in the use state are both configured to be parallel to the thickness direction of the steel plate:

[0006] The first upright post is slidably matched with the seat frame body along a first direction and is rotationally matched with the seat frame body around the first direction. The first upright post is used for defining the position of the steel plate along the first direction. A limiting structure for limiting or releasing the position of the first upright post relative to the seat frame body is provided between the first upright post and the seat frame body;

[0007] The second upright post is detachably connected to the seat frame body and is used for defining the position of the steel plate along a second direction.

[0008] Further, the seat frame body includes a fixed shaft, the axis of the fixed shaft extends along the first direction, and the first upright post is slidably matched with the fixed shaft along the axis of the fixed shaft and is rotationally matched with the fixed shaft around the axis of the fixed shaft.

[0012] Further, the plug pin includes a pin and a first connecting chain. One end of the first connecting chain is connected to the first upright post, and the other end is connected to the pin. The pin is configured to be allowed to be inserted into any one of the insertion holes.

[0013] Further, a guiding block is arranged in the first upright post, and the guiding block is in sliding fit with the pin along the extending direction of the first upright post.

[0014] Further, the second upright post is inserted into the seat frame body along its own extending direction, and a second connecting chain is connected between the bottom end of the second upright post and the seat frame body.

[0015] Further, a limiting groove is arranged on the seat frame body, and a protrusion that is in sliding fit with the limiting groove along the extending direction of the second upright post is arranged on the second upright post.

[0016] Further, a limiting plate is further included. Both ends of the limiting plate are connected to the seat frame body and form a receiving space for receiving the removed second upright post between the limiting plate and the seat frame body.

[0037] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0038] An embodiment of the first aspect of the present utility model provides a steel plate seat frame, as Figure 1 and Figure 2 shown, including a seat frame body 1, a first column 2, and a second column 3. The seat frame body 1 is used to carry the steel plate, and the extending directions of the first column 2 and the second column 3 in the use state are both configured to be parallel to the thickness direction of the steel plate:

[0039] The first column 2 is slidably engaged with the seat frame body 1 along a first direction and rotatably engaged with the seat frame body 1 around the first direction. The first column 2 is used to limit the position of the steel plate along the first direction, and a limiting structure 4 for limiting or releasing the limitation of the position of the first column 2 relative to the seat frame body 1 is provided between the first column 2 and the seat frame body 1;

[0040] The second column 3 is detachably connected to the seat frame body 1, and the second column 3 is used to limit the position of the steel plate along a second direction.

[0041] When the above steel plate seat frame is in use, as Figure 1 shown, the first column 2 can slide relative to the seat frame body 1 along the first direction. After sliding to a suitable position, as Figure 2 shown, the position of the first column 2 relative to the seat frame body 1 can be limited by the limiting structure 4. The first column 2 can limit the position of the steel plate along the first direction. At the same time, the second column 3 can limit the position of the steel plate along the second direction. Since the extending directions of the first column 2 and the second column 3 in the use state are both configured to be parallel to the thickness direction of the steel plate, and the second direction, the first direction, and the extending direction of the first column 2 are perpendicular to each other pairwise, the first column 2 and the second column 3 can limit the position of the steel plate in its own extending direction.

[0042] In the above embodiment, since the first column 2 can slide relative to the seat frame body 1 along the first direction, the steel plate seat frame can adapt to steel plates of different sizes, can limit steel plates of different sizes, and has a wider application range.

[0043] In an alternative embodiment, the first direction may be the width direction of the steel plate, and the second direction may be the length direction of the steel plate. That is to say, the first upright column 2 can limit the position of the steel plate along the width direction of the steel plate, and the second upright column 3 can limit the position of the steel plate along the length direction of the steel plate. Thus, during the starting and stopping processes, the steel plate is prevented from directly hitting the inner wall of the transport vehicle under the action of inertia, protecting the transport vehicle.

[0044] When the steel plate seat frame is in a non-use state, the limitation of the position of the first upright column 2 relative to the seat frame body 1 can be released through the limiting structure 4, and the first upright column 2 can be rotated around the first direction so that the first upright column 2 is laid down and fits closely with the seat frame body 1. At the same time, the connection between the second upright column 3 and the seat frame body 1 is cancelled and the second upright column 3 fits closely with the seat frame body 1 as a whole, making the steel plate seat frame have a smaller height dimension and facilitating the storage of the steel plate seat frame.

[0045] In an alternative embodiment, a plurality of first upright columns 2 may be configured, and a plurality of second upright columns 3 may be configured. As Figure 1 shown, two first upright columns 2 are configured, and two second upright columns 3 are configured. The two first upright columns 2 are arranged oppositely along the first direction, and the two first upright columns 2 respectively abut against both sides of the steel plate along the first direction. The two second upright columns 3 are arranged oppositely along the first direction, and the two second upright columns 3 jointly abut against one side of the steel plate along the second direction. When in use, two steel plate seat frames can be arranged oppositely along the second direction for combined use, and the two second upright columns 3 of another steel plate seat frame jointly abut against the other side of the steel plate along the second direction.

[0046] In an alternative embodiment, as Figure 2 and Figure 3 shown, the seat frame body 1 includes a fixed shaft 11, and the axis of the fixed shaft 11 extends along the first direction. The bottom end of the first upright column 2 is slidably engaged with the fixed shaft 11 along the axis of the fixed shaft 11 and is rotatably engaged with the fixed shaft 11 around the axis of the fixed shaft 11.

[0047] When it is necessary to adjust the position of the first upright column 2 along the first direction, the user can make the first upright column 2 slide relative to the fixed shaft 11. When it is necessary to lay down the first upright column 2, the user can make the first upright column 2 rotate relative to the fixed shaft 11. The operation is convenient and simple.

[0048] Specifically, both ends of the fixed shaft 11 can be fixedly connected to the seat frame body 1 by means of welding, clamping, screw connection, etc.

[0049] When two first upright columns 2 are configured, two fixed shafts 11 can also be correspondingly configured, and the two first upright columns 2 are slidably and rotatably engaged with the two fixed shafts 11 one by one.

[0050] In an alternative embodiment, to make the structure of the steel plate seat frame more compact and to avoid interference between the first upright post 2 and the seat frame body 1 in the use state, as Figure 4 shown, one end of the first upright post 2 close to the fixed shaft 11 has an avoidance opening 22, and the limiting top plate 13 in the seat frame body 1 extends into the avoidance opening 22. A limiting structure 4 may be provided between the limiting top plate 13 and the first upright post 2.

[0051] In an alternative embodiment, as Figure 4 shown, the seat frame body 1 is connected with a stacking limiting member 8. A limiting channel 81 is defined around the bottom of the stacking limiting member 8, and the top of the stacking limiting member 8 is configured to extend into the limiting channel 81 of the upper seat frame body 1.

[0052] Wherein, the limiting channel 81 may be, but is not limited to, a rectangular parallelepiped channel. The top of the stacking limiting member 8 is wedge-shaped and can penetrate into the limiting channel 81 from the bottom end of the upper seat frame body 1, so as to define the horizontal positional relationship between two adjacent steel plate seat frames up and down and ensure the stability of the stacking structure of the steel plate seat frames in the unused state.

[0053] In an alternative embodiment, as Figures 5 to 7 shown, the limiting structure 4 includes a plug pin 41 and a plurality of plug holes 42. The plurality of plug holes 42 are spaced apart along a first direction on the seat frame body 1, and the depth directions of the respective plug holes 42 are all parallel to the extending direction of the first upright post 2 in the use state; the plug pin 41 is connected to the first upright post 2, and the plug pin 41 is configured to be allowed to be inserted into any one of the plug holes 42.

[0054] During use, as Figure 7 shown, when it is necessary to limit the position of the first upright post 2 relative to the seat frame body 1, the plug pin 41 can be inserted into a suitable plug hole 42. Since the depth directions of the respective plug holes 42 are all parallel to the extending direction of the first upright post 2 in the use state, the plug holes 42 can not only limit the sliding of the first upright post 2 relative to the seat frame body 1 along the first direction, but also limit the rotation of the first upright post 2 around the first direction, thereby locking the position of the first upright post 2 relative to the seat frame body 1.

[0055] When it is necessary to release the restriction on the first upright post 2, the plug pin 41 in the plug hole 42 can be pulled out manually, and the operation is simple and convenient.

[0056] Specifically, the above-mentioned plug holes 42 may be formed in the limiting top plate 13.

[0057] In an alternative embodiment, as Figure 7As shown, to prevent the loss of the bolt 41, the bolt 41 includes a pin 411 and a first connecting chain 412. One end of the first connecting chain 412 is connected to the first upright post 2, and the other end is connected to the pin 411. The pin 411 is configured to be inserted into any one of the insertion holes 42.

[0058] The first connecting chain 412 can realize the connection between the pin 411 and the first upright post 2, effectively preventing the loss of the pin 411.

[0059] The first connecting chain 412 can be, but is not limited to, an iron chain.

[0060] The above-mentioned pin 411 can be inserted into the insertion hole 42 under the action of gravity. As Figure 7 shown, the outer diameter of the above-mentioned pin 411 can gradually increase in the direction from left to right, so that when it is inserted into the insertion hole 42, it can be in interference fit with the insertion hole 42.

[0061] In an alternative embodiment, to ensure that the position of the pin 411 relative to the seat frame body 1 is relatively stable during use, a guide block 21 is provided inside the first upright post 2, and the guide block 21 is in sliding fit with the pin 411 along the extending direction of the first upright post 2.

[0062] During operation, the guide block 21 guides the pin 411, and the user can pull the pin 411 left and right as Figure 7 shown. The left and right directions in the above are the actual vertical directions, realizing the locking and unlocking of the position of the first upright post 2. When the pin 411 is inserted into the insertion hole 42, it will not shake under the limit of the guide block 21. Figure 7

[0063] In an alternative embodiment, as Figure 8 and Figure 9 shown, the second upright post 3 is inserted into the seat frame body 1 along its own extending direction, and a second connecting chain 9 is connected between the bottom end of the second upright post 3 and the seat frame body 1.

[0064] In the above embodiment, the second upright post 3 is inserted, which is convenient for the installation of the second upright post 3. The setting of the second connecting chain 9 can prevent the loss of the second upright post 3 after disassembly.

[0065] The second connecting chain 9 can be, but is not limited to, an iron chain.

[0066] Specifically, as Figure 9 shown, one end of the second connecting chain 9 can be connected to the bottom surface of the second upright post 3, and the other end is bent around the side surface of the seat frame body 1 and then connected to the side surface of the seat frame body 1.

[0067] In an alternative embodiment, as Figure 5 and Figure 9 ​As shown, a guiding piece 12 is fixedly connected to the end beam 14 of the seat frame body 1. A limiting groove 121 is recessed in the guiding piece 12, and a protrusion 31 is provided on the second upright post 3 and is in sliding fit with the limiting groove 121 along the extending direction of the second upright post 3.

[0068] When installing the second upright post 3, the protrusion 31 can be aligned with the limiting groove 121, and the protrusion 31 is inserted into the limiting groove 121. Under the action of gravity, the second upright post 3 is inserted into the seat frame body 1.

[0069] The insertion structure between the seat frame body 1 and the second upright post 3 is simple, which is convenient for the disassembly and assembly of the seat frame body 1.

[0070] The top end of the limiting groove 121 can have a horn-shaped guiding groove, and the opening of the guiding groove gradually increases from bottom to top, so as to facilitate the alignment of the protrusion 31 with the limiting groove 121.

[0071] In an alternative embodiment, as Figures 1 to 3 shown, the steel plate seat frame further includes a limiting plate 5. Both ends of the limiting plate 5 are connected to the seat frame body 1 and form a receiving space 6 for receiving the disassembled second upright post 3 between the limiting plate 5 and the seat frame body 1.

[0072] After the second upright post 3 is disassembled, it can be placed in the receiving space 6 between the limiting plate 5 and the seat frame body 1, making the structure of the steel plate seat frame more compact in the non-use state.

[0073] Both ends of the limiting plate 5 can be fixedly connected to the seat frame body 1 by means of welding, clamping, screw connection, etc.

[0074] In an alternative embodiment, as Figures 1 to 3 shown, a lapping member 7 for lapping the top end of the second upright post 3 is connected between the limiting plate 5 and the seat frame body 1.

[0075] After the second upright post 3 is disassembled, the bottom end of the second upright post 3 is connected to the seat frame body 1 through a second connecting chain 9, and the top end of the second upright post 3 can be lapped on the lapping member 7, so as to ensure the stability of the second upright post 3.

[0076] Wherein, the lapping member 7 can be columnar. When there are two second upright posts 3, there are also two lapping members 7.

[0077] In an alternative embodiment, as Figure 1 shown, a lifting ring 32 for lapping on the lapping member 7 can be provided at the top end of the second upright post 3.
