[0034] More specifically, in the above specific embodiment, the driven base plate 202 is hinged to the fixing holes provided on the left and right longitudinal frames of the main frame 1 through the driven base plate fixing shaft 205 .

[0035] More specifically, in the above-mentioned specific embodiment, a flip-type supporting leg 4 is respectively provided at the lower part of the left and right sides of the main frame 1 near the front end. When the vehicle is in the loading and unloading state, the flip-type supporting leg 4 can be flipped downward and unfolded and supported on the ground. When the vehicle is in the transportation state, the flip-type supporting leg 4 can be flipped upward and attached to the bottom of the main frame 1.

[0036] More specifically, in the above-mentioned specific embodiment, it also includes a plurality of fixed bottom plates 3, and these plurality of fixed bottom plates 3 are spaced apart on the upper part of the main frame 1, and are alternately connected with the plurality of foldable bottom plate assemblies 2 mentioned above to form the platform bottom plate of the steel coil transport flatbed semi-trailer.

[0037] It can be understood that the above is only one embodiment of the steel coil transport flatbed semi-trailer with a foldable bottom plate of the utility model. In the above embodiment, it is only illustrated that the platform bottom plate of the steel coil transport flatbed semi-trailer is composed of four fixed bottom plates 3 and six intermittently arranged foldable bottom plate components 2 (that is, every two foldable bottom plate components 2 form a group, and three groups of foldable bottom plate components 2 are separated by four fixed bottom plates 3). Fig.11 shown.

[0038] In some other embodiments, the platform floor of the steel coil transport flatbed semi-trailer may also be composed of a plurality of foldable floor assemblies 2 arranged in a continuous manner and at least one fixed floor 3, such as Fig.13 or Fig.14 As shown, or other combinations, such as Fig.12 The structure shown is composed of a plurality of intermittently arranged foldable bottom plate assemblies 2 and a plurality of intermittently arranged fixed bottom plates 3.

[0044] The working principle of the steel coil transport flatbed semi-trailer with foldable bottom plate provided by the utility model is as follows:

[0045] When the foldable floor assembly 2 is unfolded, Figure 1 , Figure 3 , Figure 5 As shown, the steel coil transport flatbed semi-trailer with a foldable bottom plate provided by the utility model can be used as an ordinary flatbed semi-trailer and can be used to transport containers and various logistics bulk goods.

[0046] When the foldable bottom plate assembly 2 is folded up, refer to Figure 2 , Figure 4 , Figure 6 As shown, the steel coil transport flatbed semi-trailer with a foldable bottom plate provided by the utility model can be used as a steel coil transport vehicle, and can be used to transport steel coils 5, steel pipes and other round tubular or cylindrical coils or pipes.

[0047] Among them, when the foldable floor assembly 2 needs to be unfolded, the specific operation process is: the active floor 201 can be driven to move by extending the piston rod of the cylinder 203 outward, so that the active floor 201 pulls the driven floor 202 to move toward the direction close to the main frame 1 until the active floor 201 pulls the driven floor 202 to be flush with the top surface of the main frame 1.

[0048] When the foldable floor assembly 2 needs to be folded up, the specific operation process is: the active floor 201 can be driven to move by retracting the piston rod of the cylinder 203 inward, so that the active floor 201 pulls the driven floor 202 to move away from the main frame 1 until the piston rod of the cylinder 203 is fully retracted.

[0049] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the contents of the present utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present utility model.
