Description

21 tons of heavy big volume gas of axle unload the powdered goods tank car

The utility model relates to a kind of tank car that delivers powdered goods, refers to that particularly a kind of axletree unloads the powdered goods tank car by the big volume gas that national standard is designed to 21 tons of weights.

At present, 21 of place in operation tons of heavy gas of axle unload the powdered goods tank car on the China railways line, and its carrying capacity is all less than 60 tons, and maximum only reaches 59 tons, on average is about about 55 tons.Trace it to its cause and mainly contain 2 points: the one, the fluid bed design in the tank car is very unreasonable, and structure mostly is the long oblique slot type of single chamber, the center of gravity height, the tank body space that poor stability, fluid bed itself are occupied is bigger, thereby causes the internal dimensions of the loading space of tank car to descend; The 2nd, tank car itself adopts the Q235-A structural section to make usually, and its tank skin is thicker, and deadweight strengthens, and makes its load carrying ability descend relatively.

The purpose of this utility model is exactly to provide a kind of under the heavy prerequisite of 21 tons of axletrees of standard, and the big volume gas that can increase substantially its load carrying ability unloads the powdered goods tank car.

For realizing this purpose, the designed heavy big volume gas of 21 tons of axles of the utility model unloads the powdered goods tank car, has a horizontally-arranged tank body, and tank body combines as a whole by pillow pulling device and little underframe, and car load drops on the bogie truck.Be provided with on the top of tank body that charging door is formed and outer ladder, be provided with in the bottom of tank body that wind ash pipeline is formed, underframe associate member and wind braking composition.Fluid bed is arranged on the inner bottom part of tank body, and its bracing frame by the gasification board that is arranged in tank base central authorities, the sideslip ramp that is installed in the gasification board both sides, the little landslide plate that is installed in the gasification board end and supporting gasification board and landslide plate is formed.Gasification board is made of two end gasification boards and two middle part gasification boards again, and two end gasification boards are provided with two middle part gasification board relative tilts respectively, and its angle position is respectively to making two ash-collecting cone hoppers on the tank body.The fluid bed bottom is separated into two bins by median septum, promptly end gasification board and middle part gasification board and the plate that comes down accordingly thereof constitute a bin, each bin is provided with a blast pipe, and the level inclination α=8-18 of each piece gasification board °, the level inclination β=38-50 of sideslip ramp °.

The level inclination of above-mentioned each piece gasification board is preferably α=15 °, and the level inclination of sideslip ramp is preferably β=45 °, and the width of gasification board is used for the tank body that diameter is 2400-3100 between 500-1200mm.Gasification board can adopt syntheticfibres vinylon to make, and tank body can adopt novel weathering resistant steel 09CuPTiXt to make.

Advantage of the present utility model is that its fluid bed adopts the big oblique slot type design in two Room, each bin can work independently or collaborative work, the level inclination combined value of its gasification board and sideslip ramp combines the requirement of carrying capacity, make the car load center of gravity low, good stability, improve the stowage of tank body effectively, and then increased carrying capacity.By adopting new weathering steel material that the wall thickness of this tank body is reduced, reach the effect that increases load-carrying simultaneously thereby reduce to conduct oneself with dignity.Under the heavy situation of 21 tons of axletrees of standard, carrying capacity of the present utility model can reach 61 tons, loads the 2-7 ton than other similar vehicle of using on the present railway more.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

The heavy big volume gas of 21 tons of axles shown in the figure unloads the powdered goods tank car, adopts no central sill tank body monocoque structure, and its horizontally-arranged tank body 2 combines as a whole by pillow pulling device 10 and handle frame 1, and car load drops on the new commentaries on classics 8A type bogie truck 9.Be provided with charging door on the top of tank body 2 and form 3 and outer ladder 4, be provided with in the bottom of tank body 2 that wind ash pipeline forms 5, underframe associate member 6 and wind braking composition 8.Inner bottom part at tank body 2 is provided with fluid bed 7, and this fluid bed 7 is made up of the gasification board that is arranged on tank body 2 bottom center, the sideslip ramp 12 that is installed in the gasification board both sides, the little landslide plate 13 that is installed in the gasification board end and their bracing frame 14.This gasification board is made up of two end gasification board 11a, 11d and two middle part gasification board 11b, 11c.Two end gasification board 11a, 11d are provided with two middle part gasification board 11b, 11c relative tilts respectively, and its angle position is respectively to making two ash-collecting cone hoppers 15 on the tank body 2.Fluid bed 7 bottoms are separated into two bins by median septum 16, and promptly end gasification board and middle part gasification board and the plate that comes down accordingly thereof constitute a bin, and each bin is only established a blast pipe (not shown).The level inclination α of gasification board 11a-d gets 15 °, the level inclination β of sideslip ramp 12 gets 45 °, this mainly is that (the static angle of repose of cement powders is 40-45 ° to the fluidization property of having considered cement powders, dynamically angle of repose is about 6 °), requirement in conjunction with the tank car bearing capacity, reduce the space that fluid bed 7 is occupied to greatest extent in tank body 2, thereby enlarge the internal dimensions of the loading space of tank body 2, increase its carrying capacity.Tank body 2 adopts novel weathering resistant steel 09CuPTiXt to make, and can reduce the thickness of tank skin like this, increases load carrying ability further by alleviating to conduct oneself with dignity to reach.Gasification board 11a-d then adopts syntheticfibres vinylon to make, by bolt 17, foundary weight bar 18, and rubber weather strip 19 be pressed on the bracing frame 14.The gasification board extensibility of this syntheticfibres is little, the intensity height, wear-resistant, only the power tension by both direction is just passable during installation, does not need the support of traditional breaker plate, thereby has both simplified the structure, manpower and materials have been saved, the defective of not having the sort of easy material folding of plain sail gasification board again, its permeability is good, carries effect to obtain bigger improvement.In addition, as can be seen, the thin bilge construction of gasification board 11a-d both sides is a landslide surface from Fig. 6, Fig. 7, and cement powders can natural downslide at this face, has eliminated and has deposited grey dead angle, has reduced remnant ash rate.The diameter of tank body 2 is 3000mm in the present embodiment, and the width of gasification board 11a-d is 700mm, and its cement carrying capacity is 61 tons.

Structure of the present utility model is equally applicable to the heavy tank car of 25 tons of axletrees of standard, can reach more than 75 tons in its carrying capacity under this situation.
