Abstract
The invention relates to a railway vehicle sand-proof pedal, which comprises a box-type box body consisting of a coaming and a closing plate, wherein the coaming is internally welded with a pedal, the upper edge of the coaming is fixed with a frame, an L-shaped connecting iron welded with the coaming is arranged below the frame, and the connecting iron is welded and fixed with an iron floor; the enclosing plate close to one side of the end beam is welded and fixed with the end beam, and the enclosing plate far away from one side of the end beam is welded and fixed with the edge beam; the side door structure is characterized in that a turnover plate is connected to the upper portion of the enclosing plate through a hinge, a doorsill is welded at the front end of the turnover plate, an L-shaped groove is formed in the inner side of the doorsill, and two groove walls of the L-shaped groove are suitable for respectively abutting against sealing rubber strips at the lower opening of a side door of a vehicle. The section form of the doorsill is optimized, the contact mode with the side door is improved, and a better sealing effect is achieved; the coaming and the pedal are of an integrated box type structure, the side profile of the coaming is consistent with that of the vehicle body structure, and the rigidity of the coaming is obviously improved.
Description
Technical field
The present invention relates to rail vehicle pedal structure, belong to body construction design field.
Background technology
Pedal set up by passenger train is to meet the requirement of passenger getting on/off under different platform height, considers that aesthetic considerations, pedal structure to be made are coordinated with car load simultaneously.Because pedal is positioned at below vehicle side door, there is poorly sealed problem in pedal threshold and side door.So, in the country that some dusts storm are bigger, it is desirable to pedal has the function that sand-proof invades.Additionally, general pedal is U-shape structure, there is the problem of insufficient rigidity in this structure, and longitudinally vibration is acutely.
Summary of the invention
The technical problem to be solved is, overcomes the disadvantages mentioned above of prior art, it is provided that a kind of rolling stock sand-proof pedal, possesses preferable sand-proof sealing property and higher rigidity, it is to avoid longitudinally vibration.
In order to solve above technical problem, the rolling stock sand-proof pedal that the present invention provides, including the box box body being made up of coaming plate and shrouding, it is welded with pedal in described coaming plate, described coaming plate top edge is fixed with frame, having the L-type with coaming plate welding below described frame and be connected ferrum, described connection ferrum is fixed with ferrum floor welded；Coaming plate near end carriage side is welded and fixed with end carriage, and the coaming plate away from end carriage side is fixed with side bar welding；Having turnover panel, the front end of described reprint to be welded with threshold by gemel connection above described coaming plate, the inner side of described threshold has L-type groove, and two cell walls of described L-type groove are adapted to prop up the sealing joint strip of vehicle side door end opening.
In order to solve the problems referred to above, the present invention also further characterized in that
1, the weld of described coaming plate and end carriage, coaming plate and the weld of side bar, be respectively welded baffle plate.
2, described coaming plate is by twice bending and molding of one piece of corrosion resistant plate.
3, described pedal is Seem Lablab Album stricture of vagina steel plate, and pedal offers some preventing and treating deposition rainwater and the slotted hole of sandy soil.
In order to solve the problems referred to above, the present invention also further characterized in that
The present invention optimizes the form of fracture of threshold, improves the way of contact with side door, reaches preferable sealing effectiveness；Coaming plate uses integral type box-structure with pedal, and coaming plate side profile is consistent with body construction, and its rigidity significantly improves；Meanwhile, in order to realize, pedal is anti-skidding, prevent from depositing rainwater, sand etc., employing Seem Lablab Album stricture of vagina steel plate, and increases slotted hole.Whole pedal mainly uses welding manner to connect, simple in construction, and outward appearance is beautiful, and manufacturability is preferable.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the axonometric chart of rolling stock sand-proof pedal of the present invention.
Fig. 2 is pedal threshold sectional view of the present invention.
Fig. 3 is the scheme of installation (removing cover plate) of rolling stock sand-proof pedal of the present invention.
In figure, label is schematically as follows:
1-coaming plate, 2-shrouding, 3-pedal, 4-frame, 5-connects ferrum, 6-ferrum floor, 7-end carriage, 8-side bar, 9-turnover panel, 10-threshold, 11-side door, 12-sealing joint strip, 13-baffle plate.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment rolling stock sand-proof pedal, including the box box body being made up of coaming plate 1 and shrouding 2, in coaming plate 1, it is welded with pedal 3, pedal 3 is Seem Lablab Album stricture of vagina steel plate, and pedal 3 offers some preventing and treating deposition rainwater and the slotted hole of sandy soil；Coaming plate 1 top edge is fixed with frame 4, has the L-type with coaming plate 1 welding and is connected ferrum 5, connect ferrum 5 and be welded and fixed with ferrum floor 6 below frame 4；Coaming plate 1 near end carriage 7 side is welded and fixed with end carriage 7, and the coaming plate 1 away from end carriage 7 side is welded and fixed with side bar 8；Having turnover panel 9 by gemel connection above coaming plate 1, the front end of reprint is welded with threshold 10, and the inner side of threshold 10 has L-type groove, and two cell walls of L-type groove are adapted to prop up the sealing joint strip 12 of vehicle side door 11 end opening.As it is shown in figure 1, the weld of coaming plate 1 and end carriage 7, coaming plate 1 and the weld of side bar 8, be respectively welded baffle plate 13.
In this example, coaming plate uses material to be steel plate 3-06Cr19Ni10, and pedal material is Seem Lablab Album stricture of vagina steel plate 4-06Cr19Ni10, and threshold material is steel plate 2-06Cr19Ni10.The material of whole pedal is rustless steel, and periphery is fixed by the way of welding with underframe.
Tests prove that, this pedal has preferable sealing characteristics and higher rigidity, produces a desired effect.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
