Tank car currently used for shipping the concentrated sulfuric acid has 60t grades of load-carrying of G11 type, G11S type and 70t grades of load-carrying
GS70 type tank car, has been all made of center sill structure, including tank body, chassis, walks on stage, steam jacket etc., can satisfy the concentrated sulfuric acid substantially
Transportation demand.
But there are the following problems for this structure:
It circulates 1. existing tank body heating nested structure is unfavorable for steam inside when heating, influences entire heating effect, and
Steam jacket bracket uses angle steel, and the event for tearing tank body occurred.In manufacturing process, heating cage plate is from tank base into tank body
Portion's group pair, at the support angle bar of steam jacket surrounding using grind cut by the way of assembled, complex process is time-consuming, and appearance matter
It is poor to measure.
2. concentrated sulfuric acid tank car is in accident shape with the continuous improvement that technological progress, the whole society require transportation safety
There is also certain hidden danger for security against leakage under state.
3. the tank body wall thickness of existing vehicle is 10mm, it is not able to satisfy the requirement of life cycle management, some vehicles make
Tank body is even replaced with palpus excavation filling mend after 3 or 4 repair in shop phases；
4. can seam is not detected a flaw, occurs the thing that weld corrosion perforation causes dielectric leakage in tank in practical application
Part.
Summary of the invention

Further, when vehicle topples under accident condition in order to prevent, manhole, pumping device are broken by hard hit
The problem of causing medium leakage after damage, the tank car further include safety device, and safety device includes flat along tank body section
Row two groups of safety barriers of setting, the safety barrier includes curved plate, fixed frame and at least one gusset；
Curved plate is fixedly mounted on cylinder, and is matched with the acquaintance of the shape of cylinder, and fixed frame is fixedly mounted on arc
On bottom plate, and it is greater than the height at the top of manhole and pumping device to drum surface to the height of drum surface at the top of fixed frame；
Gusset is arranged in rectangular frame side and is connected with curved plate.Position installation between two groups of safety barriers needs people to be protected
The attachmentes such as hole and pumping device.
In order to further enhance the intensity of fixed frame, fixed frame includes outer rim and the abdomen that is arranged in outer rim
Plate.
It is installed for the ease of the lifting of safety barrier, while mitigating weight, reduce the windage of vehicle during transportation, institute
State offered on web at least one rise unloading resistance hole.
Further, in order to ensure tank body integral strength simultaneously reduce self weight, as far as possible save cost, the front head, after
End socket, cylinder are all made of Q345R production, and the cylinder wall thickness being located between two safety barriers on cylinder is 14mm, cylinder
The wall thickness of rest part is 12mm.
Further, the upper saddle tearing that intense impact situation lower shell is installed in its underpart in order to prevent causes to be situated between in tank
Matter leakage, is connected between the cylinder and upper saddle by connecting plate.
The beneficial effects of the present invention are:
(1) steam jacket supporting structure of the present invention uses drainage measure rational deployment, multiple circumferential support setting ventholes with
And blow vent, it heats and is laid out air inlet, exhaust outlet and discharge outlet in place on cage plate, so that steam circulates in steam jacket
When can be used effectively, improve heating efficiency, save the energy.
(2) corrosion resistance that tank body is improved by the way of rationally increasing cylinder wall thickness, not only solves part tank body not
The problem of being able to satisfy life cycle management requirement, avoid vehicle causes medium leakage in tank to be drawn because partial structurtes corrosion is excessive
The hidden danger seriously endangered is sent out, and cheap, manufacturing process is simple, mature.
(3) every banjo fixing butt jointing of tank body carries out non-destructive testing, and improves the quality of can seam, avoids medium in tank
It is revealed from commissure.
(4) two sides of manhole and pumping device are provided with safety barrier, the junction of tank body and upper saddle is additionally arranged connecting plate,
Plug welding is increased at saddle coupling board, this series of measure improves vehicle medium leakage in anti-tank in the state of accident
Safety.
(5) steam jacket bracket uses channel steel, and stability is more preferable, and the bottom of steam jacket increases backplate, improves steam jacket
Presentation quality after assembling.
