FIG. 3 is a schematic view of an interior area floor of a cargo floor according to an embodiment of the present disclosure. The interior area floor 2 shown in fig. 3 is the floor on the left side in fig. 1. As shown in fig. 1 and 3, longitudinal stopper devices 6 are provided at both longitudinal ends, i.e., both left and right ends in fig. 3, of the floor 2 in the inner area. The left end and the right end are respectively provided with four longitudinal stop devices 6 which are arranged at intervals. The inner floor 2 is provided with transverse stopping devices 5 at its two transverse ends (i.e., the upper and lower ends in fig. 3), and four transverse stopping devices 5 are provided at intervals at the upper and lower ends, respectively. The middle of the floor 2 of the interior area is also provided with 8 transverse stop devices 5, which are arranged at intervals in the longitudinal direction. In fig. 3, the central 8 transverse stops 5 are arranged in two rows, one above the other.

The inner zone floor 2 in fig. 3 can accommodate two containers of relatively small transverse dimension in the transverse direction. Fig. 4 is a cross-sectional view of the vehicle compartment corresponding to section B-B in fig. 3. As shown in fig. 3 and 4, the lateral stopping devices 5 located at the upper side in fig. 3 and the lateral stopping devices 5 located at the upper middle row are used for laterally stopping the left-hand container in fig. 4 and limiting the lateral movement of the container. The two longitudinal stop means 6 located above the left in fig. 3 and the two longitudinal stop means 6 located above the right serve to longitudinally stop the container on the left in fig. 4, limiting the longitudinal movement of the container.

Similarly, the lower transverse stop 5 in fig. 3 and the lower middle transverse stop 5 serve to stop the right-hand container in fig. 4 laterally, limiting its lateral movement. The two longitudinal stop devices 6 located below the left side in fig. 3 and the two longitudinal stop devices 6 located below the right side in fig. 4 serve to longitudinally stop the container on the right side in fig. 4, limiting the longitudinal movement of the container.

For containers of smaller longitudinal dimensions, the interior region floor 2 shown in fig. 3 can also accommodate at least two containers in the longitudinal direction. Fig. 5 is a cross-sectional view of the vehicle compartment corresponding to section C-C in fig. 3. As shown in fig. 3 and 5, the lateral stop device 5 located on the upper left side in fig. 3 serves to laterally stop the left-hand container in fig. 5, and the lateral stop device 5 located on the upper right side in fig. 3 serves to laterally stop the right-hand container in fig. 5. The interior area floor 2 shown in figure 3 is suitable for a pallet having a base size of 1150mm x 1350 mm.

On the basis of the technical scheme, the inner area floor 2 is also provided with a double-claw stop device 7 which is arranged in the middle of the inner area floor 2 and used for limiting the container 8 to move along the longitudinal direction or the vertical direction after the container 8 moves to the right position.

In addition, a plurality of cylindrical balls 21 are arranged on the inner area floor 2 in a plurality of rows, and the cylindrical balls 21 in each row are arranged at intervals in the longitudinal direction. The longitudinal stop means 6 are in the same alignment as the cylindrical balls 21.

FIG. 6 is a schematic view of another interior area floor in the cargo floor according to an embodiment of the present application. The inner zone floor 2 shown in fig. 6 is the floor on the right in fig. 1. As shown in fig. 1 and 6, the longitudinal stopper devices 6 are provided at both longitudinal ends, i.e., both left and right ends in fig. 6, of the floor 2 in the inner area. The left end and the right end are respectively provided with four longitudinal stop devices 6 which are arranged at intervals. The inner area floor 2 is provided with transverse stopping devices 5 at its two transverse ends (i.e., the upper and lower ends in fig. 6), and six transverse stopping devices 5 are provided at intervals at the upper and lower ends, respectively. A double claw stop 7 is provided in the middle of the inner zone floor 2. The difference from fig. 3 is that in fig. 6 no transverse stop 5 is provided in the middle of the inner floor 2, which allows to accommodate a larger-sized container 8. The interior area floor 2 shown in figure 6 is suitable for use with a container having a base size of 1150mm x 2700 mm.

Fig. 1 is merely an example, and in practical applications, the interior area floor 2 may be provided only at one longitudinal end of the doorway area floor 1, which corresponds to a car door located at an end of a car. Alternatively, the inner area floor 2 may be provided at both longitudinal ends of the doorway area floor 1, corresponding to the middle position of the car door in the vehicle compartment.

For the case that the inner area floors 2 are disposed at both longitudinal ends of the doorway area floor 1, the positions and the number of the stopper devices on the inner area floors 2 at both ends may be completely the same or different, and this embodiment is not limited. The stop device can be arranged in the manner shown in fig. 1 with reference to the left interior floor 2, or with reference to the right interior floor 2 of fig. 1.

In addition, the container 8 can also be arranged on the door area floor 1, so that a stop device is also arranged on the door area floor 1 for fixing the container 8. The stop means may comprise lateral stop means 5 provided at both lateral ends of the floor 1 in the doorway area for limiting lateral movement of the container 8 after the container 8 is moved into position. The stop device may also comprise a double-jaw stop device 7, provided in the middle of the floor 1 in the doorway area, for limiting the movement of the container 8 in the longitudinal or vertical direction after the container 8 is moved into position.

The functions of the transverse stopping device 5, the longitudinal stopping device 6 and the double-claw stopping device 7 are used for fixing the container 8 and limiting the movement of the container 8, and the respective structures can be in various forms. For each stop device, the embodiment provides a specific implementation manner:

The double-claw stopper device 7 includes: a double claw stopper base 71, a first stopper 72, a second stopper 73, and an elastic member 74. Wherein, the double-claw stop base 71 is embedded in the section bar, and the double-claw stop base 71 is provided with a third sunken space sunken downwards relative to the floor. The first stopper 72 is rotatably disposed on the double-claw stopper base 71, and the first stopper 72 can rotate downward relative to the double-claw stopper base 71 to be accommodated in the third recessed space or rotate upward to be higher than the floor surface. The second stopper 73 is rotatably disposed on the double-claw stopper base 71, and the second stopper 73 can rotate downward with respect to the double-claw stopper base 71 to be accommodated in the third recessed space or rotate upward above the floor surface. The first stop member 72 and the second stop member 73 are restricted from rotating downward after rotating above the floor surface to achieve a tight engagement therebetween and maintain an upright position. The top of the first stopper 72 and the second stopper 73 respectively overlap the bases of the two side pallets 8 for stopping the longitudinal direction and the vertical direction of the pallets 8.

The elastic member 74 is disposed between the double-claw stopper base 71 and the first stopper 72, or between the double-claw stopper base 71 and the second stopper 73, and is used for driving the first stopper 72 and the second stopper 73 to rotate to be accommodated in the third recess space when the restraining force between the first stopper 72 and the second stopper 73 is eliminated.

The first stopper 72, the second stopper 73 and the elastic member 74 may be constructed and assembled in various manners. When the first stopper 72 and the second stopper 73 are in a free state, they are turned downward to be hidden in the third recessed space by the elastic force of the elastic member 74 so as not to interfere with the movement of the container 8 on the floor. When the container is moved into position, the operator manually pulls the first stop 72 and the second stop 73 to a position where they can be restrained from each other, causing them to jam against each other and remain in that position. When the container is unloaded, the operator manually pulls the first stopper 72 and the second stopper 73 to shift the positions of the first stopper 72 and the second stopper 73 from each other, and the first stopper 72 and the second stopper 73 rotate downward and retract under the elastic force of the elastic member 74 without being restricted from each other.

The length direction of the double-claw stopper base 71 extends in the longitudinal direction, and the first stopper 72 and the second stopper 73 are provided at the middle of the double-claw stopper base 71. Two ends of the double-claw stop base 71 are respectively provided with a cylindrical ball 21, the cylindrical ball 21 is rotatably connected to the side wall of the double-claw stop base 71 through a rotating shaft, and a rolling bearing is arranged between the cylindrical ball 21 and the rotating shaft.

The transverse stop means 5, the longitudinal stop means 6 and the double pawl stop means 7 in the above description are only examples and other means may be used. The layout of the stop devices on the floor is not limited to the manner provided in the present embodiment.

The freight floor provided by the embodiment can meet the transportation requirements of the container on loading, operation and the like, and goods can be loaded in the container in advance to wait for loading, so that the time of loading the vehicles at stations is greatly reduced, the utilization rate of the vehicles is improved, and the goods conveying time is also shortened. In addition, the problems of collision, extrusion and falling of goods in the process of getting on and off the vehicle for many times are avoided, and the breakage rate is reduced.

The embodiment also provides a railway vehicle which comprises the freight floor provided by any one of the contents. The rail vehicle provided by the embodiment has the same technical effects as the freight floor.
