Abstract
The invention relates to a large-volume coal hopper car in a type with outwards projected end walls. The large-volume coal hopper car is characterized by comprising a vehicle body, wherein the vehicle body comprises two end walls in symmetrical and inwards inclined arrangement, the upper section of each end wall is formed by a plate structure through twice bending and folding, a groove with the trapezoidal cross section is formed, the lower section of each end wall is formed by a plate structure through five times of bending and folding, a rectangular outer convex groove positioned in the middle part of the lower section is formed, and the rectangular outer convex groove extends to a position between one wheel pair arranged at one side near the end wall. The large-volume coal hopper car has the advantages that the space volume between the wheel pairs can be sufficiently utilized, the car body volume can be increased on the premise of not influencing the coal unloading, in addition, the end walls have higher rigidity, and the stress deformation cannot easily occur. The large-volume coal hopper car can be widely used for the large-volume coal hopper car used for railway wagons.
Description
Technical field
The present invention relates to a kind of railway transport vehicle, particularly the large volume coal hopper car of a kind of headwall raised type.
Background technology
The existing Railway Coal hopper car of China, primarily of compositions (as shown in Figure 6, Figure 7) such as car body 6, bogie truck 7, coupler and draft gears 8.The headwall 9 of car body 6 is clinoplane 10, because coal unloads under need leaning on deadweight, so the angle that headwall 9 tilts will exceed coal angle of repose.Interfere 11 with wheel for avoiding the clinoplane 10 of end wall of car body, clinoplane 10 can only protrude wheel to 11 outside (as shown in Figure 7), and the angle of inclination of clinoplane 10 will exceed coal angle of repose, to such an extent as to the volume at car body two ends is caused to there is larger waste; In addition, the easy stress deformation in overall headwall inclined-plane in this case.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of can utilize wheel between spatial volume, increase vehicle body volume, improve the large volume coal hopper car of headwall raised type of headwall rigidity.
For achieving the above object, the present invention takes following technical scheme: the large volume coal hopper car of a kind of headwall raised type, it is characterized in that: it comprises a car body, described car body comprise two symmetries slope inwardly arrange headwall, the epimere held described in each is formed through twice bending by a plate structure, and forming a cross section is trapezoidal cell body; The hypomere of described headwall is formed through five bendings by a plate structure, forms one and is positioned at rectangular convex groove in the middle part of hypomere, described rectangular convex groove stretch into a wheel near described headwall side between.
Described in two, end underframe is provided with a rectangular indentation near the middle part of the side of described headwall, be fastenedly connected inside described headwall hypomere and described end underframe and described rectangular convex slot in described rectangular indentation.
On the door-plate of the flygate mechanism side relative to described headwall of headwall described in two, be provided with a rectangular preiection, the bottom of described side door plate and described headwall hypomere is fastenedly connected and described rectangular preiection is positioned at described rectangular convex groove.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, the present invention is made up of epimere and hypomere due to headwall, and epimere is formed through twice bending by a plate structure, to form a trapezoidal cell body; Hypomere is formed through five bendings by a plate structure, rectangular convex groove in the middle part of hypomere is positioned to form one, rectangular convex groove extend near headwall side wheel between, therefore, it is possible to make full use of wheel between spatial volume, increase vehicle body volume not affecting under the prerequisite of unloading under coal.2, the epimere of headwall of the present invention and hypomere form by plate structure bending, and for existing integral planar formula headwall, headwall form of the present invention has higher rigidity, is not easy stress deformation.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention includes a car body 1, the bottom of car body 1 is provided with multiple door-opening mechanism 2, and the two ends of car body 1 connect an end underframe 3 respectively, and the bottom of each end underframe 3 is provided with two wheels to 4.Car body 1 comprise two symmetries slope inwardly arrange headwall 5, each headwall 5 comprises variform epimere 51 and hypomere 52 (as shown in Figure 2), and the epimere 51 of headwall 5 is formed through twice bending by a plate structure, to form a trapezoidal cell body; The hypomere 52 of headwall 5 is formed through five bendings by a plate structure, is positioned at rectangular convex groove 521 in the middle part of hypomere 52 to form one, and rectangular convex groove 521 stretches into a wheel near headwall 5 side to (as shown in Figure 3) between 4.Compared with headwall of the prior art, headwall 5 of the present invention obviously can increase vehicle body volume.
In above-described embodiment, as shown in Figure 4, both ends underframe 3 is provided with a rectangular indentation 31 near the middle part of the side of headwall 5, is fastenedly connected and rectangular convex groove 521 is positioned at rectangular indentation 31 inside headwall 5 hypomere 52 and end underframe 3.
In above-described embodiment, as shown in Figure 5, on the door-plate of flygate mechanism 2 side relative to headwall 5 of two headwalls 5, be provided with a rectangular preiection 21, the bottom of this side door plate and headwall 5 hypomere 52 is fastenedly connected and rectangular preiection 21 is positioned at rectangular convex groove 521.
The various embodiments described above are only for illustration of the present invention, and wherein the structure, connection mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
