Description
Technical field
This practicality relates to the compartment, is specially lightweight self-unloading and semitrailer box body.
Background technology
At present from the industry basic side, Urbanization in China, infrastructure construction are to the newly increased requirement of special-use vehicle and upgrade demand very greatly, and growth space is wide.Especially the development of the improvement of road conditions and transportation for road transport has been created good condition, also provides the broad space to the lightweight dumping car simultaneously.
The quickening that the domestic trade industry is flourish, also impel dumping car to change to weight-saving from the overload type in past, old structure of past is to the change of new construction, dumping car is because center of gravity is too high, in transportation or unloading process, often occur because of heavy high unstable phenomenon, roll-over accident occurs especially easily, causes damage.Still come with some shortcomings and have much room for improvement in other side.Joy comes never more than once but sorrows never come singly, and dumping car has run into again new problem.So a lot of special-purpose depots are to falling deadweight and falling on the center of gravity and make an effort.
Improve constantly with powerful in the status in the world, the socialist construction of motherland is fast-developing.Part as special vehicle is developing equally.In the urban modernization that day by day accelerates and the process of small towns urbanization, both effectively promoted economic fast development, spurred dearly again the development that auto-industry comprise the logistics transportation automobile.China is to the huge demand of the long-term maintenance of the basic goods and materials such as iron and steel, coal, nuclear power, water conservancy, traffic facilities, civil construction, skyscraper, and these goods and materials considerable parts are transported by vehicle and brought good chance.
Old structure:
1. at present existing self-unloading and semitrailer carriage is overweight, center of gravity is higher, energy consumption large, have the problem of potential safety hazard.
2. parallel welding fabrication after railway carriage or compartment underframe longitudinal member and bottom cross beam align, structural strength is lower.
3. traditional crossbeam is bending C type structure, is convenient to processing and fabricating, and mean forced distributes, and does not very generally have technology content.
4. to be that whole plate adds cross beam and upright post simple in structure for header board, bearing capacity a little less than.
5. self-unloading and semi-trailer body sheet material great majority are general steel plate, high strength steel plate.
6. side plate is combined the junction with base plate, and normal limit bear building-up is combined into two side plates folder base arrangements.
New construction:
1, now self-unloading and semitrailer carriage change material and reduce weight, and underframe longitudinal member drops on vertical parallel contact on the chassis cross-member, and underframe longitudinal member is enclosed within the subframe outside and lowers the center of gravity.
2, the rear welding fabrication of grafting behind the two-sided flange of railway carriage or compartment bottom girder and bottom cross beam increases structural strength in the longeron of floor beam insertion single face flange.
3, the cabin floor crossbeam is two-sided on bending C type architecture basics inwardly turns over little limit and gains in strength, welding fabrication after bottom girder and bottom cross beam are pegged graft, and the both sides skirt member adopts the U-shaped beam of pipe reducer, and structure is more reasonable.
4, the whole plate of front board structure becomes corrugated structure, reduces stand column and beam quantity, and change structure strengthens intensity.
5, self-unloading and semi-trailer body sheet material are high strength steel plate, reduce curb mass and can use aluminium alloy plate.
6, new construction is that base plate extends to the side plate place, increases brace panel reinforcement junction intensity, knows overall weight and descends, and change structure is gained in strength.
The utility model content
The technical matters that this practicality solves is to provide lightweight self-unloading and semitrailer box body, to solve the shortcoming in the above-mentioned background technology.
The technical matters that this practicality solves realizes by the following technical solutions:
This practicality relates to the improvement of self-unloading and semitrailer carriage structure, improved compartment part particularly, comprise carriage chassis, side bar, column and U-girder, be arranged at the rear welding fabrication of compartment bottom girder and bottom cross beam grafting, increase structural strength in the longeron of insertion single face flange behind the two-sided flange of described floor beam, described floor beam and compartment subframe longitudinal beam are hinged, the decrease height of gravitational center, the upper articulation that is included in the compartment font lower shroud oil cylinder, the compartment is hinged on the vehicle frame and the hinged rear side plate of compartment afterbody by the hinged seat of its bottom, cabin floor and both sides side plate that the bottom surface is evenly equipped with crossbeam are welded into the compartment envelope that cross-sectional plane is U-shaped, adopt (high-strength plate) surface in the envelope and be welded to each other to be integrated, superimposed trailer adopts (aluminium alloy plate) change material can effectively reduce deadweight and gains in strength and resistance to corrosion.
Lightweight self-unloading and semitrailer box body, being arranged in the longeron that inserts the single face flange behind the two-sided in-flanges of crossbeam of base plate in compartment increases structural strength, welding fabrication after bottom girder and bottom cross beam are pegged graft,
In this practicality, the crossbeam of base plate and compartment subframe longitudinal beam are crossed over hinged, the decrease height of gravitational center, be included in the articulated oil cylinder of upper interior portion bending of compartment font lower shroud, the compartment is hinged on the vehicle frame and the hinged rear side plate of compartment afterbody by the hinged seat of its bottom, cabin floor and both sides side plate that the bottom surface is evenly equipped with crossbeam are welded into the compartment envelope that cross-sectional plane is U-shaped, and envelope inside face and being welded to each other is integrated.
