Abstract
The present invention relates to a kind of Multifunctional cab apron for railway coach, by the monoblock steel plate bending after cutting or punch forming, comprised successively from outer toward interior: cab apron face, capillary groove, threshold face, threshold riser, described cab apron face is higher than threshold face 45-56mm, the bottom surface of described capillary groove is lower than threshold face 20-30mm, described threshold riser is vertical with threshold face, the bottom land of described capillary groove longitudinally offers drain gutter along it, end and the doorframe column of described threshold face, threshold riser are welded and fixed, and end and the headwall channel-section steel of described capillary groove are welded and fixed.The multi-functional cab apron of the present invention by cab apron and door structure as a whole, and arranges capillary groove, by bending or mould punching global formation, simplifies the structure, decreases weld seam, improve Workshop Production efficiency simultaneously.This multi-functional cab apron has taken into account cab apron and door function, has good drain function, and similar passenger vehicle cab apron face all can reference higher than the structure of door.
Description
Technical field
The present invention relates to Multifunctional cab apron for railway coach, belong to track vehicle body structure design field.
Background technology
Domestic 25G type car end adopts rubber windshield, and headwall cab apron place structure, the above is a plane, and simple shape is formed by checkered steel plate bending.End door adopts folding door, and end door is welded on cab apron, and on door, plane is higher than cab apron face, and cab apron and door are two separate parts, and door bank structure is comparatively complicated, needs mould compressing.Door full weld is crossing plane on face, and greatly and easily produce welding deformation, technological requirement is high for welding job amount, and assembling trouble, production efficiency is low.The seal request of butt welded seam is higher, there is the hidden danger that rainwater corrodes car body into the car.This cab apron structure has certain limitation, is only applicable to the situation of cab apron face lower than door.Along with the continuous developing of market abroad, run in early stage increases gradually, and the requirement of projects cab apron is also different from domestic 25G type bassinet structure, and for the demand of cab apron higher than door, existing cab apron structure can not meet the demands.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of Multifunctional cab apron for railway coach.
In order to solve above technical matters, Multifunctional cab apron for railway coach provided by the invention, it is characterized in that: by the monoblock steel plate bending after cutting or punch forming, comprised successively from outer toward interior: cab apron face, capillary groove, threshold face, threshold riser, described cab apron face is higher than threshold face 45-56mm, the bottom surface of described capillary groove is lower than threshold face 20-30mm, described threshold riser is vertical with threshold face, the bottom land of described capillary groove longitudinally offers drain gutter along it, described threshold face, end and the doorframe column of threshold riser are welded and fixed, end and the headwall channel-section steel of described capillary groove are welded and fixed.
Further, the cell wall of described capillary groove near threshold face is vertical with threshold face, and the cell wall of described capillary groove near cab apron face is inclined-plane, and the angular range of inclined-plane and level is 30 °-45 °.
Further, the lower surface in described cab apron face is welded with strength beam near capillary groove side.
Further, the aperture of described drain gutter is 10mm.
Further, cab apron is the checkered steel plate of thickness 4mm.
The multi-functional cab apron of the present invention solves the structure difficult problem of cab apron face higher than door, realizes good drain function, also solves cab apron and the separate problem of door simultaneously, decreases weld seam, improve work efficiency.
Cab apron and door unite two into one by the present invention, and a face meets the requirement of end every bank, and a face meets rubber windshield cab apron operating needs, and cab apron face, higher than door face, is connected by capillary groove between two planes, and the draining of capillary groove open interior, plays waterproof action.
The multi-functional cab apron of the present invention by cab apron and door structure as a whole, and arranges capillary groove, by bending or mould punching global formation, simplifies the structure, decreases weld seam, improve Workshop Production efficiency simultaneously.This multi-functional cab apron has taken into account cab apron and door function, has good drain function, and similar passenger vehicle cab apron face all can reference higher than the structure of door.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is Multifunctional cab apron for railway coach cutaway view schematic diagram of the present invention.
Fig. 2 is Multifunctional cab apron for railway coach schematic top plan view of the present invention.
Under number in the figure schematic diagram: 1-cab apron face, 2-capillary groove, 3-threshold face, 4-threshold riser, 5-drain gutter, 6-doorframe column, 7-headwall channel-section steel, 8-strength beam.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment Multifunctional cab apron for railway coach, shaping by the monoblock steel plate bending after cutting, comprised successively from outer toward interior: cab apron face 1, capillary groove 2, threshold face 3, threshold riser 4, cab apron face 1 is higher than threshold face 3 about 51mm, the bottom surface of capillary groove 2 is about 25mm lower than threshold face, threshold riser 4 is vertical with threshold face 3, the aperture that the bottom land of capillary groove 2 longitudinally offers drain gutter 5(drain gutter along it is 10mm), end and the doorframe column 6 of threshold face 3, threshold riser 4 are welded and fixed, and end and the headwall channel-section steel 7 of capillary groove 2 are welded and fixed.As shown in Figure 1, the cell wall of capillary groove 2 near threshold face 3 is vertical with threshold face, and the cell wall of capillary groove 2 near cab apron face 1 is inclined-plane, and the angular range of inclined-plane and level is 30-45 °.
In order to ensure intensity and the rigidity in cab apron face, the lower surface in cab apron face 1 is welded with strength beam 8 near capillary groove 2 side.The multi-functional cab apron entirety of the present embodiment adopts the checkered steel plate of thickness 4mm, serves anti-skidding effect.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
