Description
Technical field
The utility model relates to the truck of the mass freights such as delivery ore, coal, building materials, refers to particularly a kind of railway corrosion-resistant steel Ore Gondola.
Background technology
Truck is the principal mode vehicle in railway transportation, and quantity is maximum in existing railway truck total amount, and it is mainly born and transports the task that coal, ore, ore deposit are built the mass freights such as goods and materials, timber, steel, also can be used for transporting some heavy duty equipments.Truck can be divided into two classes by unloading mode difference :-class is the open-top car that is applicable to artificial or mechanical handling operation, another kind of be applicable to large industrial enterprise, stand, fixedly marshalling transportation in column between harbour, the open-top car of unloading with tipper.
Along with the future development of railway freight to heavy haul transport, the raising axle is heavy, the load-carrying of increase bicycle has become the general measure that the countries in the world heavy haul transport is effective and unanimously take.For the railway ore open-top car, also thereupon to improving the future development that axle is heavy, increase every linear meter(lin.m.) load-carrying, the weight of its car body is also correspondingly increasing.
At present, the railway ore open-top car mainly by car body, the bogie truck that is used for supporting body form, be arranged on the vertical two ends of car body coupler and draft gear and draw bar device, be arranged on the wind brake equipment of vehicle bottom and form with the hand brake device of car body relevant equipment etc.Car body is made of underframe, headwall and side wall assembly welding again as the main body of lade.Wherein: underframe is mainly formed by central sill, sleeper beam, crossbeam, longitudinal beam and floor assembly welding, headwall is mainly formed by assembly weldings such as end plate, top end rail, cross band and corner posts, side wall is mainly formed by assembly weldings such as top chord, pillow column, lateral column and framed side wallboards, and the three encloses Container Loading space and monocoque structure jointly.Headwall and side wall are mainly used in bearing the lateral pressure of lade and the transverse force that vehicle produces in operational process, the pressure that the side wall of particularly vertically arranging need to bear is larger, therefore side wall must have enough strength and stiffness, to guarantee the truck Operation safety.
In order to address the above problem, the iron and steel material shaped that the scientific research personnel of railway territory generally adopts thickening, widen comes the assembly welding side wall, and consolidates welding effect by setting up the parts such as strengthening rib, brace panel.But there is following defective in design like this: one, consist of side wall various thickenings, widen that the section bar number of components is many, structure is heavy, will inevitably increase the weight of side wall, there is the dimensional parameters of the headwall, underframe etc. of annexation also to need corresponding increase with side wall, and then causes the deadweight of Ore Gondola car load significantly to increase.They are two years old, generally all be provided with underside gate and Zhong Men for handling goods and personnel's turnover on side wall, underside gate and middle door also need to configure corresponding unlatching and latching device, all doorframes, door-plate and associate member thereof all need welding and/or are installed on side wall, cause complex structure, technique various, make inefficiency, labor strength is large, particularly increase itself and the difficulty that is connected of headwall, underframe etc., be unfavorable for improving the manufacturability of whole car body assembling.They are three years old, because the constituent elements quantity of side wall is many, different, the place is easy to occur the moisture erosion problem at face of weld, particularly serious at underside gate and middle door place's oxide etch phenomenon, therefore its service life is relatively short, maintenance and repair is more frequent, thereby has increased manufacturing and the operating cost of railway ore open-top car.
How effectively to reduce the heavy from height of railway ore open-top car under the prerequisite of guaranteeing the operation of vehicle heavy-duty safety, be the difficult problem that the railway scientific research personnel needs to be resolved hurrily always.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of simple and reliable for structure, own wt is light, intensity and toughness good, maintenance intervals is long, the car load packaging technology is good, can effectively improve the railway corrosion-resistant steel Ore Gondola of vehicular transport ability, to satisfy the requirement of the lightweight of the heavy railway ore open-top car of macro-axis, heavy lift.
