Description
Technical field
The present invention relates to a kind of railway truck, specifically, relate in particular to the carriage body construction of railway truck.
Background technology
Traditional goods train carriage structure such as Fig. 5, Fig. 6 and shown in Figure 7, by component set-ups such as floor 1, framed side wallboard 2, end wall panel 3, end carriage 6, corner post 7, corner post plate 8, curb girder 9, crossbeam 10, central sill 11 and lateral columns 12, wherein the two ends on floor 1 are welded on respectively on the two butt beams 6, the dual-side on floor 1 is welded on respectively on two curb girders 9, in the both sides of curb girder 9 framed side wallboard 2 is set, the two ends of framed side wallboard 2 are welded on the cooresponding corner post 7 by corner post plate 8, the base of framed side wallboard 2 and curb girder 9 welding.Lateral surface at framed side wallboard 2 is provided with many lateral columns 12, the bottom of lateral column 12 and curb girder 9 riveted joint and assembly weldings.1 two ends are provided with end wall panel 3 on the floor, and weld mutually with end carriage 6 on the base of this end wall panel 3, the dual-side of end wall panel 3 and 7 welding of cooresponding corner post.1 bottom also is provided with crossbeam 10 and central sill 11 on the floor, works to strengthen the compartment bottom strength.The deficiency that above structure exists is:
1, because corner post adopts die mould angle steel or clod wash rectangle hollow shaped steel usually, perhaps adopt channel-section steel and corner post plate assembly welding to form, in process of production, Fabrication procedure is more, has increased manufacturing complexity and cost of product; In addition, the compartment total weight is bigger, influences load-carrying and improves, and can increase locomotive energy consumption, is unfavorable for energy savings.
2, use the shaped steel curb girder, can increase the compartment manufacturing cost, also increased the weight in compartment, make locomotive in operational process, increase energy consumption.Carry out assembly welding again after lateral column and the curb girder riveted joint, operation is many, also can increase the tooling cost of compartment in manufacturing process.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of and makes simply, can effectively reduce total weight and cost and improve the acerous pillar of the railway truck compartment of load-carrying.
Technical scheme of the present invention is as follows: a kind of railway truck is acerous pillar compartment, comprise the floor, be positioned at the framed side wallboard and the end wall panel that is positioned at the two ends, floor of both sides, floor, its key is: the base of described framed side wallboard bends inwards, the corresponding sides overlap joint assembly welding on this bending part and floor, the two ends on described floor are bending upwards, form upper overturning, this upper overturning overlaps mutually with the bottom of corresponding end wallboard, and it is fixing by welding, described end wall panel is up big and down small trapezoidal variable section shape, the dual-side distortion bending of end wall panel forms the right angle flange, the corresponding end overlap joint assembly welding of this flange and framed side wallboard.
The present invention has cancelled corner post, corner post plate and curb girder on the basis of conventional confguration, between framed side wallboard and the end wall panel, between end wall panel and the floor and between floor and the framed side wallboard all by flange overlap joint assembly welding, like this under the prerequisite that guarantees compartment bulk strength and rigidity, reduced part, reduce Fabrication procedure, reduced manufacturing cost; Simultaneously, reduce the compartment total weight, improved load-carrying, reduced locomotive energy consumption, helped energy savings.
Position in the close end, two ends of above-mentioned framed side wallboard is welded with the side cross band that three of upper, middle and lower are parallel to each other, all be welded with the end cross band that three of upper, middle and lower are parallel to each other on the described end wall panel, the two ends of described end cross band be positioned at cooresponding two the side cross bands of sustained height and directly link to each other, and fixing by welding.End cross band and cooresponding side cross band are formed framed structure, have improved the compartment bulk strength.
Be welded with central sill and crossbeam in the bottom on above-mentioned floor, central sill distributes along the length direction on floor, and crossbeam distributes along the Width on floor, and crossbeam is vertical mutually with central sill.Crossbeam and central sill work to strengthen the compartment bottom strength, to improve the load-carrying capacity in compartment.
In order further to improve the intensity of bottom, compartment, be provided with longitudinal beam in the both sides of above-mentioned central sill, weld the bottom surface on described longitudinal beam and floor, and parallel with central sill.
Lateral surface at above-mentioned framed side wallboard is provided with lateral column, and this lateral column is corresponding with crossbeam, and the welding of the end of the medial surface of lateral column bottom and crossbeam.Lateral column and cooresponding crossbeam are formed framed structure, also can play the effect that improves the compartment bulk strength.
Above-mentioned lateral column is equicohesive variable section structure, and the cross section of lateral column is a rectangle, is the boundary with the bottom, reduces gradually to upper section from critical, also reduces gradually to lower section from critical.Above structure has realized the equal strength optimal design of framed side wallboard, has further improved the intensity in compartment.
Beneficial effect: the present invention compares with conventional art, and is simple in structure, and processing and manufacturing is easy, and operation is few, low cost of manufacture, and whole total weight is light, has improved load-carrying, helps reducing locomotive energy consumption, energy savings.
