[0012] Embodiments will now be described way of example only with reference to the accompanying non-limiting Figures in which: [0013] Figure 1 is a front view of a transport board according to an embodiment; [0014] Figure 2 is a top view of Figure 1; [0015] Figure 3 is a schematic view showing mounting the transport board onto a locking member of a chassis; [0016] Figure 4 is a front view of the chassis of a container-platform rail wagon according to an embodiment before the transport board being mounted thereon; [0017] Figure 5 is a top view of Figure 4; [0018] Figure 6 is a front view of the chassis of the container-platform rail wagon according to the embodiment after the transport board being mounted thereon; [0019] Figure 7 is a top view of Figure 6; and [0020] Figure 8 is a schematic view of the transport boards in storage which are stacked.

DETAILED DESCRIPTION

[0021] Figure 1 is a front view of a transport board according to an embodiment; Figure 2 is a top view of Figure 1; and Figure 3 is a schematic view showing mounting the transport board onto a locking member of a chassis. As shown in Figures 1 to 3, a detachable cargo transport board according to the embodiment includes a board body 1, and multiple annular sleeves 2 are fixedly provided on the board body 1 and are each configured to cooperate with a locking member 10 on each chassis unit of a container rail wagon.

[0022] The detachable cargo transport board may be directly placed on the chassis of the container rail wagon, and in this way, the improved container rail wagon may be used as a platform rail wagon. The movement of the transport board with respect to the chassis may be confined by the cooperation between the annular sleeve and the locking member on the chassis unit. Thus, the detachable cargo transport board has a simple structure and can be mounted quickly, thereby saving modification time and cost.

[0023] The annular sleeve 2 may be a segment of bushing. The bushing has a periphery wall fixedly connected to the board body 1, and an inner hole configured to cooperate with the locking member 10, and a cross section of the bushing has a shape matching that of an outer wall of the locking member 10. As shown in Figure 3, the cross section of the bushing may be rectangular, and the bushing has one side wall surface fixedly connected to the board body 1, and other two side walls, facing each other in a vertical direction, each provided with a hole 21 matching the outer wall of the locking member. The holes 21 cooperate with the locking member 10 to fix the position of the board body 1.

[0024] In order to adapt the transport board to the chassis of the container rail wagon to improve the transport capacity, the board body 1 is configured to have a rectangular shape.

[0025] As shown in Figures 1 to 3, the annular sleeve 2 is a universal container corner fitting which is a standard fitting and can be purchased directly from the market according to the model of the container rail wagon, thus has a great universality and does not need to be produced specially, thereby saving the cost.

[0026] In order to increase the contact area between the transport board and the chassis to further improve the reliability and stability of the cargo transportation, the board body 1 is configured as a flat board as shown in Figure 1.

[0027] As shown in Figures 4 to 8, an embodiment further provides a container-platform dual-purpose rail wagon, which includes a chassis 20 and multiple containers mounted on the chassis. The chassis 20 includes multiple I-shaped chassis units 30 which are connected end to end, and each of the chassis units 30 includes a longitudinal beam 301 and two cross beams 302 respectively fixed on two ends of the longitudinal beam 301. A locking member 10 protruding upwards is fixed on a top surface of each of two ends of each cross beam 302. The container generally is a rectangular box, and four corners of a bottom of the container are each provided with a universal container corner fitting for cooperating with the locking member 10 on the chassis unit 30. The dual-purpose rail wagon further includes multiple detachable cargo transport boards 100 according to any of the embodiments described above, and the annular sleeves of the detachable cargo transport board 100 are correspondingly sleeved on the locking members 10 of the chassis unit.

[0028] The structure of the container rail wagon with all containers being removed from the chassis 20 is shown in Figures 4 and 5, and the structure of the container rail wagon with the detachable cargo transport board 100 being mounted on the chassis is shown in Figures 6 and 7. Referring to Figures 6 and 7, the detachable cargo transport board is generally formed by welding several universal container corner fittings and a high-strength bearing board body together. When it is required to mount the transport board on the container wagon, the transport board is hoisted up, and after aligning the container corner fittings on the transport board respectively with the locking members on the container wagon, the transport board may be placed down onto the container wagon. Then, each of the locking members 10 is rotated to lock the transport board on the container wagon, in this way, the container wagon has the bearing surface of a platform shape, thus may transport cargos such as vehicles, beams .

[0029] Multiple detachable cargo transport boards 100 may be prepared as specific accessories, and by detaching the container from the chassis and mounting and fixing the detachable cargo transport board onto the chassis, an existing container rail wagon may realize the function of the platform rail wagon of transporting cargos such as vehicles, beams; and by removing the specific accessories, the original function of the container wagon may be recovered. Therefore, the switching between a container wagon and a platform wagon may be realized by dissembling and assembling the transport board, thereby obtaining a dual-purpose rail wagon. Thus the idleness rate or transportation with empty container may be reduced, and the utilization efficiency of the wagon is improved. Additionally, as shown in Figure 8, the transport boards may be stacked in multiple layers which may only occupy a small space and be easier to be transported, and may be repeatedly disassembled and reassembled.
