Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a bottom plate structure which can adapt to double-layer loading and unloading. Background Art

[0002] In order to improve equipment utilization and economy and avoid empty return, vehicles carrying electric bicycles and motorcycles will drop the middle plate to the bottom plate when returning to carry other types of LTL or express goods. However, the commonly used double-decker transport vehicles currently have a flat rear end of the bottom plate to ensure normal wheeled driving when loading and unloading electric vehicles. However, after the middle plate falls, due to the thickness of the middle plate itself, there is a step difference of 60 to 80 mm in height, which greatly affects the loading and unloading of return goods. Utility Model Content

[0003] In view of the defects existing in the prior art, the purpose of the utility model is to provide a bottom plate structure that can adapt to double-layer loading and unloading. Under the premise of ensuring that the electric transport vehicle can be wheeled for loading and unloading, when a single layer is loaded on the return trip, there is a plane transition between the middle plate and the original bottom plate, which does not affect the loading and unloading machinery or the entry and exit of personnel.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a bottom plate structure that can adapt to double-layer loading and unloading, applied to a double-layer transport vehicle, the body of the double-layer transport vehicle includes a bottom plate and a liftable middle plate, the rear end of the bottom plate is provided with a sunken slope structure, and the rear end of the middle plate is provided with an upward slope structure; when single-layer loading is performed, the middle plate falls onto the bottom plate, and the upward slope structure and the sunken slope structure are combined to form a plane, which is convenient for loading and unloading materials; when double-layer loading is performed, the middle plate rises, the upward slope structure is separated from the sunken slope structure, and the material can be wheeled and rolled over the sunken slope structure.

[0005] A further improvement is that the upward slope structure includes a flat plate and a first inclined plate, the flat plate is flush with the top surface of the middle plate, the front end of the inclined plate is flush with the bottom surface of the middle plate, and the rear end of the inclined plate is connected to the flat plate.

[0006] A further improvement is that a reinforcing round steel is provided at the connection between the rear end of the inclined plate and the flat plate.

[0007] Further improvements are: the sunken slope structure includes a rear frame and a second inclined plate; the rear frame is located at the rear end of the bottom plate, and the top surface of the rear frame is flush with the lowered flat plate; the second inclined plate is compatible with the first inclined plate, and the front end of the second inclined plate is flush with the top surface of the bottom plate, and the rear end of the second inclined plate is flush with the top surface of the rear frame.

[0008] A further improvement is that the first inclined plate and the second inclined plate have the same inclination.

[0009] A further improvement is that the rear frame includes a support beam and a vertical plate, the upper end of the vertical plate is bent forward to form a first folded edge connected to the rear end of the second inclined plate, and the lower end of the vertical plate is bent forward to form a second folded edge connected to the support beam.

[0010] A further improvement is that the end of the second folded edge is bent upward to form a flange portion, and the flange portion is fixedly connected to the support beam.

[0011] A further improvement is that: the first folded edge is arranged to be higher at the front and lower at the back.

[0012] A further improvement is that a first reinforcing plate is provided between the first folded edge and the support beam.

[0013] A further improvement is that a second reinforcing plate is provided between the vertical plate and the supporting beam.

[0014] The beneficial effects of the utility model are:

[0015] The utility model makes the rear end of the carriage floor into a sunken slope structure, the sunken depth is consistent with the thickness of the middle plate, and the tail end of the middle plate is also provided with an upward slope structure, the two have the same slope, and after the middle plate falls to the floor, the upper planes of the two are basically flush. When double-layer loading is carried out, the electric vehicle can roll over the slope, and when single-layer loading is carried out, after the middle plate falls to the floor, the upper planes of the two are basically flush, without height difference, and loading and unloading machinery or personnel can enter and exit normally.
