Description
Technical field
This utility model belongs to petroleum storage and transportation field, relates to petroleum transported and the storage facilities of a kind of Large Oil tank car, especially
It relates to a kind of bearing-type multistage variable cross-section tank service truck oil tank.
Background technology
Full extension, semi-trailer oil truck are mainly used to transport and store the spin-off of oil, such as gasoline, diesel oil, crude oil, lubrication
Oil and coal tar etc., have the advantage that conevying efficiency is high, economize on resources.According to the applicant understood, the most conventional extension, semitrailer-type entirely
Oil truck, its oil tank many employings straight tube structure, owing to the sectional area of straight tube structure is little, center of gravity is high, causes tank body longer, mobility
Poor.It addition, use flat construction before and after tank body, the moisture caused in tank in medium is discharged after cannot concentrating deposition, limits
Oil tank is in the application in high-quality petroleum transported filling field.
Finding through retrieval, the Chinese patent of Patent No. 01209604.0 discloses a kind of reducing tank body liquid gas transport
Semitrailer, including vehicle frame, is arranged on the traction frame assembly of vehicle frame front end, the cylinder being fixedly mounted on vehicle frame, and barrel front end sets
Having conical shell, be provided with shell ring in the front end of conical shell, conical shell cross section is that inequilateral bores column structure, cylinder, taper
Linearly, three is connected integral structure, and sheave is arranged on below path shell ring, and this structure makes for cylinder and shell ring top
Tank body i.e. maintains original container pressure, and the weight being pressed on tractor also increases, and increases the pull strength of tractor, due to
Without improving height of chassis above ground, make the center of gravity that tank body holding is relatively low, also take full advantage of the space on tractor afterbody, increase and load
Capacity, shortens full car length, and volume increases.This semitrailer is oil tank volume (including shell ring, the conical shell) peace that will increase
It is contained in tractor afterbody, the useful load of car load vehicle frame is not affected, but the oil tank volume that this part increases also is limited,
Not can exceed that the useful load of tractor, and bring bigger pressure to tractor afterbody.It addition, in this part patent of conical shell
Function only as the effect connecting shell ring with cylinder.
Utility model content
For the defect overcoming existing prior art to exist, the utility model proposes one and can expand tank volume, again
Adapt to dynamic characteristic in oil truck transportation, the bearing-type multistage variable cross-section tank service truck oil tank of thorough blowdown.
