More importantly, the semitrailer can also play a certain promoting role in the organization form of logistics in China.

The existing van-type semitrailer in China is additionally provided with a van body on the basis of a flat-bed semitrailer, the height inside the van body is only about 2.5 m under the height limit standard of 4 m, when some objects which are fragile and fearful to pressure and the like are transported, the wasted space is large, the cargo carrying capacity is reduced, and the transportation cost is increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a large capacity semitrailer, its semitrailer with current dull and stereotyped bottom plate compares, has bigger loading capacity.

The utility model discloses a following technical scheme realizes:

the utility model provides a large capacity semitrailer, includes the chassis assembly, installs the wheel assembly under the chassis assembly, installs the carriage assembly on the chassis assembly, the chassis assembly includes a spandrel girder and symmetry and installs the keel frame in the spandrel girder both sides, the spandrel girder is including pulling section, wheel erection section and pulling section and wheel erection section between the interlude, the interlude height is less than and pulls section and wheel erection section, is higher than ground height.

Further: the keel frames on two sides of the bearing beam are V-shaped.

Further: the middle of the carriage assembly is provided with a layer of partition board, and the partition board is distributed to the tail of the carriage from the head of the carriage.

Further: the section of the clapboard is A-shaped.

Further: and a vertical carriage frame is arranged in the middle of the carriage assembly.

Further: the carriage frames are telescopic, and each carriage frame is provided with a telescopic cylinder which is vertically telescopic.

Compared with the prior art, the utility model have following advantage:

firstly, the utility model discloses a reduce semitrailer interlude ground clearance, increased the actual loading space in carriage, more goods can be transported in single pass, reduced the cost of transportation.

The V-shaped keel frame enables goods in the carriage to slightly incline inwards, and the risk of goods falling outwards in the process of stacking the goods is reduced.

Thirdly, the clapboard is designed into an A shape, so that the bearing capacity is increased.

Fourthly, the telescopic cylinder on the carriage frame can jack up the upper plate in the middle section of the carriage. When the goods are loaded, the upwards rolled tarpaulin still can shield a part of area of the side face of the carriage, so that the goods are influenced to enter and exit, the upper plate is jacked, and the goods with higher height can be conveniently loaded.

In the figure: 1. a chassis assembly; 1.1, a bearing beam; 1.11, a trailing section, 1.12 and a middle section; 1.3, a wheel mounting section; 1.2, keel frame; 2. a wheel assembly; 3. a carriage project; 4. a partition plate; 5. a carriage frame; 6. a telescoping cylinder.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The utility model provides a large capacity semitrailer, includes chassis assembly 1, installs wheel assembly 2 under chassis assembly 1, installs carriage assembly 3 on chassis assembly 1, chassis assembly 1 includes a spandrel girder 1.1 and symmetry and installs keel frame 1.2 in spandrel girder 1.1 both sides, spandrel girder 1.1 is including dragging interlude 1.11, wheel installation section 1.13 and dragging interlude 1.12 between section 1.11 and the wheel installation section 1.13, interlude 1.12 highly is less than and drags section 1.11 and wheel installation section 1.13, is higher than ground level.
