Therefore, by setting the thickness t to satisfy 30mm≦t≦50mm, it is possible to save costs while ensuring that the strength requirements of rail vehicles such as straddle-type monorail trains on the floor 1 are met. For example, when the thickness t is less than 30mm, the thickness of the wheel disassembly floor block 5 is relatively thin, which may not meet the strength requirements of rail vehicles such as straddle-type monorail trains on the floor 1, that is, deformation or deformation may occur when multiple passengers stand on it. When the thickness t is greater than 50 mm, the thickness of the wheel dismounting and assembling floor block 5 is relatively thick. At this time, the entire wheel dismounting and assembling floor block 5 is heavy and the cost is high. Further optionally, the thickness t satisfies: t=30mm.

Optionally, the longitudinal maximum width of the wheel access opening 111 is greater than the diameter of the wheel 2. For example, the width of the wheel inspection opening 111 in the longitudinal direction of the floor 1 is greater than the diameter of the wheel 2 and the size of the wheel inspection opening 111 is larger, so that the daily inspection and maintenance of the wheel 2 can be carried out more conveniently.

According to a further embodiment of the present disclosure, referring to FIGS. 1 to 4, the inspection floor board 4 may be installed at the opening 11 through at least one fixing bracket 12. Further, as shown in Figs. 1 to 4, some of the fixed brackets 12 can also support the inspection floor block 4 and the wheel disassembly floor block 5 at the same time. In this way, the number of fixed brackets 12 can be saved, and the floor block can be inspected. The connection between 4 and the wheel disassembly and assembly floor block 5 can be tighter and neater.

Furthermore, in order to reduce noise transmission, a sealing member 124 may also be provided between the inspection floor board 4 and the floor 1.
