A kind of general-purpose box car
(1) technical field:
A kind of general-purpose box car belongs to the railway transportation instrument, is a kind of railway truck specifically.
(2) background technology:
The Sudan is owing to domestic political economy reason, the railway transportation slower development, the transport vehicle car is very backward, ubiquitous problem is that integral structure is undesirable, the car body distortion is serious, vehicle is low tenure of use, and the box car of full car being established four pairs of car doors exists own wt big especially, can not actv. satisfies the requirement of its domestic railway transportation.
(3) summary of the invention:
The problem to be solved in the present invention provides a kind of reasonable integral structure at above-mentioned shortcoming exactly, can effectively reduce deadweight, satisfies the general-purpose box car of the domestic railway transportation requirement of the Sudan.Its technical scheme is as follows:
It comprises car body, brake equipment, coupler and draft gear and bogie truck.Its gordian technique is that car body comprises underframe, side wall, headwall and roof, and the roof two ends have ventilator, and side wall constitutes the plate column type side wall by side plate and lateral column, and has car door on side wall, and car door is supported by door pillar.
Compared with prior art the present invention has following beneficial effect:
1, adopts box-shaped and dead front type section structure in a large number, form rational whole stress frame structure, make full use of the load-carrying capacity at each position, and have identical or close rigidity and minimum stress gradient, reach ideal carrying effect, prolong vehicle tenure of use.
2, the present invention reduces the steel structure of car body deadweight under the prerequisite that does not reduce rigidity, makes structure have bigger load-carrying capacity.
3, car door is made up of opposite opened all steel folding door and fold-down door, does not increase the car body deadweight when increasing the car door area, has improved cargo handing speed.

(5) specific embodiment:
Referring to accompanying drawing, the present invention includes car body, brake equipment, coupler and draft gear and bogie truck, its gordian technique is that car body is an all steel welding integral carrying structure, comprises underframe 1, side wall 6, headwall 8 and roof 7.
Underframe 1 comprises central sill 13, curb girder 14, sleeper beam 16, end carriage 10 and cross bearer 12.Central sill 13 is formed by two second font steel assembly weldings, is positioned at the middle part of underframe along the longitudinal direction of underframe; Curb girder 14 is parallel to central sill 13 and is positioned at the both sides of underframe; End carriage 10 is positioned at the two ends of underframe; Cross bearer 12 is to be welded with web 12c between upper cover plate 12b and lower cover 12a, constitutes I shape section beam, and it is installed between two curb girders 14 along the horizontal direction of vehicle frame is parallel; Sleeper beam 16 is near end carriage 10 and be parallel to end carriage, and it is two web 16c of assembly welding between upper cover plate 16b and lower cover 16a, constitutes the two web box girders of variable section; Lay flower of hyacinth dolichos line floor 16 on the underframe.
Side wall 6 constitutes the plate column type side wall by side plate 4 and lateral column 5, and the side plate 4 of side wall 6 constitutes osed top variable section section with lateral column 5 assembly weldings, and lateral column 5 is a hat-shaped structure.
Have car door 2 on side wall 6, car door 2 is made up of opposite opened all steel folding door 21 and fold-down door 22.Door pillar 3 is installed on the curb girder of underframe, and door pillar 3 adopts clod wash hat shape steel 29 and mends plate 28 assembly weldings and constitutes closed sectional structure.
Headwall 8 is made up of end plate 19 and cross band 18, end floor beam 17 on the upper end of headwall 8 is, and the edge that joins with side wall on headwall is provided with corner post 20.
Roof 7 is formed by roof hoard 24, carline 23 and roof cant rail 27 assembly weldings, and the carline 23 of roof 7 constitutes closed sectional structure with roof hoard 24, and carline 23 is a hat-shaped structure.On the roof hoard at roof two ends, have ventilator 9, on ventilator, at interval ventilation luffer boards 25 are installed, ventilation mouth mask 26 is installed on the roof hoard covers ventilator.
