Description

Double-deck closed-type semitrailer

Technical field

The utility model relates to a kind of superimposed trailer, is specifically related to a kind of superimposed trailer with double layer carriage structure.

Background technology

Domestic existing closed-type semitrailer all is to install envelope additional on the flat bed trailer basis, and under 4 meters limit for height standards, the envelope internal height only has about 2.5 meters, during the article such as some are frangible when transporting, not to be stowed under heavy cargo, the space of waste is larger, causes cargo capacity to reduce, and traffic cost strengthens.

Summary of the invention

The utility model provides a kind of double-deck closed-type semitrailer that can improve envelope inner space and space availability ratio for the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is:

Double-deck closed-type semitrailer, comprise Vehicle body skeleton, described Vehicle body skeleton mainly consists of by chassis assembly with chassis assembly column connected vertically, the below middle front part of Vehicle body skeleton is provided with supporting leg, the below postmedian of Vehicle body skeleton is provided with wheel, rear at Vehicle body skeleton is provided with door, and chassis assembly is comprised of bottom frame and two layers of frame, and two layers of chord position are in bottom frame top; The bottom frame is connected and composed with the bottom crossbeam vertical with the bottom longeron by the bottom longeron, and the bottom longeron is respectively equipped with protruding I upwards and the II that raises up above supporting leg and wheel, connect with " recessed " template at protruding II place, on the bottom frame base plate is housed; Two layers of frame forms by two layers of crossbeam with two layers of longeron of two layers of beam vertical, on two layers of frame dividing plate is housed.

Above-mentioned closed-type semitrailer, the place is provided with the goods lifting table at the envelope inside door.

Above-mentioned closed-type semitrailer, described elevating platform structure is: be respectively equipped with track in envelope inside door both sides, the track upper end connects fixed pulley, track side surfaces is provided with main hydraulic cylinder, the main hydraulic cylinder upper end connects movable pulley, and fixed pulley is connected chain with movable pulley and connects, and the lifting arm upper end connects the chain lower end and connects supporting plate, lifting arm is controlled in orbit up-and-down movement by main hydraulic cylinder, and supporting plate also connects respectively auxiliary hydraulic actuating cylinder I, auxiliary hydraulic actuating cylinder II and mechanical brake.

The beneficial effects of the utility model are: 1) adopt Vehicle body skeleton design of the present utility model, cancelled traditional large-scale girder steel, cabin floor is declined to a great extent, center of gravity is reduced, and it is safer steady to travel, and has increased the interior height, increased envelope volume about 25%, the design of " two-layer " takes full advantage of inner height space, compartment, makes the cargo space layout more reasonable, has improved the space availability ratio of superimposed trailer.2) install lifting table additional, do not needed manpower can easily realize having improved safety of operation by cargo handing, reduced the breakage rate, be particularly useful for inflammable, explosive, frangible and other items loading and unloading; The loading and unloading of use lifting table do not need other equipment, not limited by place and personnel, cooperate hand barrow one people can finish cargo handing, and effectively saving resource is increased work efficiency, and well brings into play the economic efficacy of superimposed trailer.
