The depressed center flat wagon is characterized in that: the cross section of the middle section of the folding angle concave underframe has a convex structure, the middle section is provided with a bulge along a longitudinal axis, and two sides of the bulge are provided with concave bearing surfaces. The cross section of the middle section of the folding angle concave underframe has the convex structure, so that the height of the bearing surfaces is reduced, the space of the lower part can be fully utilized, and the size range of a piece to be carried is expanded.
Description
Technical field
The present invention provides a kind of depressed center flat car, belongs to rolling stock equipment technology field.
Background technology
Has only D in the depressed center flat car of China
5AType and D
11The type depressed center flat car can lean on weight-lifting equipment lifting goods, can satisfy the needs of equipment from the roller loading and unloading again, and other type depressed center flat car then can not be realized loading and unloading from roller; At present, be applicable to that the main vehicle of railway truck that special equipment transports is D
11The type depressed center flat car, its commercial operation speed is 120km/h, load-carrying 40t, can not satisfy overlength, overweight, transfinite, weight is greater than the special equipment of 40t, or because of overlength, overweightly need to decompose the special equipment railway transportation demand of loading transportation.
Summary of the invention
The technical issues that need to address of the present invention are through to the depressed center flat car structural development, solve weight greater than 40t, the railway transportation problem of not decomposing special equipment, can reduce the railway over-limited boundary of special equipment grade simultaneously.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: comprise that vertical bending, stage casing are lower than the fold angle type spill underframe at two ends, fold angle type spill underframe end is provided with air brake equipment, hand brake device and coupler draft gear, and the upper surface two ends are provided with the end plate that can open and close; Install the bottom changes K6 type bogie truck; The section in the stage casing of said fold angle type spill underframe is the convex shape structure, and longitudinally axis is provided with convexity, and the both sides of said convexity are recessed carrying surface.
Further improvement of the present invention is:
The convexity and the both sides carrying surface in said fold angle type spill underframe stage casing are the box beam structure.
The surface of stating the both sides carrying surface is provided with nonskid coating.
The surface arrangement of said both sides carrying surface is used for fixing the only mooring groove of catch.
Said fold angle type spill underframe adopts all steel welded structure.
Said air brake equipment comprises two whole spinning sealed type brake cylinders and brake slack adjuster, and two brake cylinders are controlled, a shared auxiliary reservoir, quickened to alleviate reservoir and pressure reducing reservoir by same air diverter valve.
Because the technological advance that has adopted technique scheme, the present invention to obtain is:
The section in fold angle type spill underframe of the present invention stage casing is the convex shape structure, and the middle part is protruding, and the both sides carrying surface is recessed, has reduced the carrying surface height, can make full use of lower space, increases the range of sizes of acknowledgement of consignment part.
The box beam structure of convexity and both sides carrying surface can alleviate deadweight, improves car body rigidity.
Can meet consumers' demand: can satisfy the transportation of existing special equipment; Adapt to simple and direct, quick, the general purpose hauling requirement of special equipment; Reduce equipment and loaded the boundary's grade that transfinites, improved safety, realized the equipment that partly the transfinites transportation of not disintegrating simultaneously; When transporting special equipment in the past, solution, improved rail transportation efficiency to the interference of railway normal transport.
Can satisfy transportation request: the bicycle load-carrying is by D
11, D
5A40t, 50t bring up to 70t, improved 70%～50%, it is lighter to conduct oneself with dignity, and under length of station line unmodified condition, has improved the transport capacity of train, has practiced thrift the locomotive traction consumption of power, has enlarged goods and has fitted fortune property.
Adopting changes K6 type bogie truck, has improved car operation speed, can weave into fast freight train, and the accelerating vehicle turnover has improved operation efficiency.The novel depressed center flat car of development has distinguished economic benefit and social benefit.
Description of drawings
Fig. 1 is a kind of structural representation of depressed center flat car;
Fig. 2 be among the figure one fold angle type spill underframe partly cut open front view;
Fig. 3 be among the figure one fold angle type spill underframe partly cut open birds-eye view;
Wherein: 1, hand brake device, 2 fold angle type spill underframe, 4, air brake equipment, 5, end catch, 6, bogie truck 7, end plate, 8, coupler draft gear, 2-1, end carriage, 2-2, sleeper beam, 2-3, draw beam, 2-4, casing, 2-5, floor, 2-6, lower cover.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is explained further details:
Shown in Figure 1, the present invention includes that fold angle type spill underframe 2, its two ends upper surface fixed charge method end plate 7, one ends are provided with hand brake device 1, coupler draft gear 8 is installed at two ends.
Fig. 2, shown in Figure 3, fold angle type spill underframe 2 adopts all steel welded structure, is welded by end carriage 2-1, sleeper beam 2-2, draw beam 2-3, casing 2-4, floor 2-5, lower cover 2-6; Wherein casing 2-4 is formed by vertical web, transversal web and dividing plate assembly welding, and casing 2-4 becomes whole fish belly body structure with floor 2-5, lower cover 2-6 assembly welding.
Fold angle type spill underframe 2 middle parts of car body are protruding, and the both sides carrying surface is recessed, the high male-type non-skid coating of the both sides wheel place of going brushing; Four mooring grooves of vertically arranging are arranged on the floor, be used for fixing only catch 5.
It is protruding that body construction is designed to the middle part, and the both sides carrying surface is recessed, can make full use of lower space; Car body middle part and both sides carrying surface are the box beam structure; The pillow outer beams adopts two web structure, and whole fold angle type spill chassis design is the whole box beam structure that vertical web is taken out fish belly, has reduced the carrying surface height; Alleviate deadweight, improved car body rigidity.
Utilize the car body end space to design air brake equipment 4.
Said air brake equipment 4 comprises two whole spinning sealed type brake cylinders and brake slack adjuster; Two brake cylinders are controlled by same air diverter valve; Reservoir, pressure reducing reservoir are alleviated in a shared auxiliary reservoir, acceleration, and adjustment device of empty weight/heavy weight, railway freight-car derailment automatic brake arrangement are installed simultaneously.
This car carrying surface is apart from the minimum 485mm of rail level, and carrying surface is longer, can reach 9790mm, can shipping height reaches the wheeled equipment that 4m, length are not more than 16m.
