Abstract
The invention relates to a special coal open cart, wherein it comprises: a bottom support, side walls, and end walls; the bottom support comprises: sleeper beam, beam, longitudinal beam, side beam and drawing beam; the side walls and end walls are mounted at two sides and two ends of bottom support, to form open cart. The invention is characterized in that: the center of bottom support is a concave. And the invention has the advantages that: 1, it can increase the capacity, reduce the weight center, and the concave can integrate the side wall and drawing beam into one frame, to utilize the support ability of each part, to obtain same rigidity and minimum stress gradient; 2, it uses high-strength sheet and bended steel, to reduce the weight without reducing rigidity.
Description
(1) technical field:
Special open car for carrying coal belongs to the railway transportation instrument, is a kind of railway truck open-top car specifically.
(2) background technology:
Existing railway truck open-top car, especially special open car for carrying coal, ubiquitous problem are that integral structure is undesirable, and own wt is big, and center of gravity is higher, and the load-carrying capacity that can not make full use of each position reaches ideal carrying effect.
(3) summary of the invention:
The problem to be solved in the present invention provides a kind of integral structure more reasonable at above-mentioned shortcoming exactly, can effectively reduce deadweight and height of gravitational center, increases vehicle body volume, and the load-carrying capacity that makes full use of each position reaches the special open car for carrying coal of the most desirable delivery effect.Its technical scheme is as follows:
It comprises underframe, side wall and headwall, and its gordian technique is that underframe comprises sleeper beam, crossbeam, longitudinal beam, curb girder and draw beam.Side wall and headwall are installed in the both sides and the two ends of underframe respectively, constitute open-top car.The central part of underframe is the concave bottom to lower recess.

(5) specific embodiment:
Embodiment one:
Referring to Fig. 1～Fig. 5, the present invention includes underframe 7, side wall 2 and headwall 1, its gordian technique is that underframe 7 comprises sleeper beam 15, crossbeam 5, longitudinal beam 8, curb girder 6 and draw beam 4, side wall 2 and headwall 1 are installed in the both sides and the two ends of underframe 7 respectively, constitute open-top car.The central part of underframe 7 is the concave bottoms 3 that are the bathtub shape to lower recess.Side wall 2 is that lateral column 11 and pillow post 10 are installed on framed side wallboard 9, constitute the slab and girder side wall of built-in lateral column, pillow post, lateral column 11 vertically is installed in the inwall of framed side wallboard 9, pillow post 10 is installed on the inwall with sleeper beam 15 cooresponding both sides wallboards, the edge, upper end of framed side wallboard 9 is top chords 16, diagonal brace 17 is installed between the both sides wallboard 9, and framed side wallboard 9 adopts the steel plate die mould to form (see figure 4).Bathtub shape concave bottom 3 is linked to be an integral body with side wall 2 and draw beam 4, and promptly built-in lateral column 11, pillow post 10 form integral body with body transom 5, longitudinal beam 5, curb girder 6, draw beam 4 and do not have the stress frame structure of central sill.Framed side wallboard is a 4mm steel plate die mould, and lateral column is the clod wash channel-section steel, and the pillow post is a variable section equal strength structure, and top chord 16 adopts clod wash wedge angle rectangle square steel.Headwall 1 is to be horizontally installed with top end rail 12 and cross band 13 on end plate 14, constitutes the plate column type structure headwall of no newel post.Top end rail 12 adopts clod wash rectangle square tube to make, and cross band 13 adopts the thick steel plate of 4mm to be pressed into the channel-section beam, and makes variable section, and end plate 14 is the 4mm plate iron.The material of carrying structure of the present invention adopts high-strength weather resisting steel Q45ONQR1 more.
Embodiment two:
Present embodiment comprises underframe 7, side wall 2 and headwall 1, and its gordian technique is that underframe 7 comprises sleeper beam 15, crossbeam 5, longitudinal beam 8, curb girder 6 and draw beam 4, and side wall 2 and headwall 1 are installed in the both sides and the two ends of underframe 7 respectively, constitutes open-top car.The central part of underframe 7 is the bathtub shape concave bottoms 3 to lower recess.
Embodiment three:
Present embodiment comprises underframe 7, side wall 2 and headwall 1, and its gordian technique is that underframe 7 comprises sleeper beam 15, crossbeam 5, longitudinal beam 8, curb girder 6 and draw beam 4, and side wall 2 and headwall 1 are installed in the both sides and the two ends of underframe 7 respectively, constitutes open-top car.The central part of underframe 7 is the bathtub shape concave bottoms 3 to lower recess; Side wall 2 is that lateral column 11 and pillow post 10 are installed on framed side wallboard 9, and lateral column 11 vertically is installed in the inwall of framed side wallboard 9, and pillow post 10 is installed on the inwall with sleeper beam 15 cooresponding both sides wallboards.
The present invention's dress has improved curve negotiation ability with the secondary framework radial steering of the applicant's development, has improved the riding quality of vehicle.Structure of the present invention is applicable to the railway truck open-top car, but is specially adapted to the railway special open car for carrying coal.
Compared with prior art the present invention has following beneficial effect:
1, chassis design is the stress frame shelf structure of no central sill, and is singly with underframe central authorities bottom design Bathtub shape concave bottom structure can increase vehicle body volume on the one hand, and the height that lowers the center of gravity reduces deadweight, bathtub The shape concave bottom is linked to be an integral body with side wall and draw beam, the lateral column of built-in side wall, pillow column and underframe sleeper beam, Crossbeam, longitudinal beam, curb girder, draw beam form whole stress frame shelf structure, takes full advantage of each position Bearing capacity makes this car body become monocoque structure, and has identical or close rigidity and minimum Stress gradient reaches optimal delivery effect.
