Abstract
The invention relates to an end door structure for a special flat wagon of a concave-bottom double-layer transporting vehicle. The end door composition for the special flat wagon of the concave-bottom double-layer transporting vehicle is characterized by comprising two end doors, which are connected with the internal side of a wagon body door frame in a relatively rotating way, wherein each end door comprises an end door frame and an end door plate; the end door frames are formed by assembling and welding crisscrossed beams; a plurality of first openings are uniformly formed in the end door frames; a plurality of second openings are uniformly formed in the end door plates; and each first opening is connected with each second opening through plug welding. The diameter of each second opening in the end door plates is 10 mm. The end door structure for the special flat wagon of the concave-bottom double-layer transporting vehicle, provided by the invention, has the advantages of good economic efficiency and high working efficiency.
Description
Technical field
The present invention relates to a kind of railway truck end door, the end door particularly about a kind of concave-bottom double-layer carrier special flat car forms.
Background technology
Concave-bottom double-layer transport vehicle is mainly used in transporting the higher automobiles such as light-duty small passenger car, SUV (sport utility vehicle), MPV (MPV multipurpose vehicle), picking-up vehicle, also can transport various miniature, the miniature car of domestic and imported.In the prior art, concave-bottom double-layer transport vehicle is a kind of vehicle that in railway transportation roadlice, Applicable scope is the widest, pattern is up-to-date.This car body composition mainly comprises underframe, two fan side walls, roof and two fan end door compositions, and often fan end door comprises the framed structure become by angle bar assembly welding and the door-plate tiled outside framed structure.For satisfied end door is light, feature flexibly, the wall thickness that door panel design thickness of slab is 2mm, angle bar adopts is 2.5mm.In prior art, be Reducing distortion, the requirement meeting dimensional accuracy, take Huck rivet to be connected between door-plate with end door frame, often fan end door designing rivet is 174.Because the accuracy requirement in the hole on door-plate hole and angle bar is higher, therefore, need when riveting to be equipped with special rivetting gun.Often rivetting gun about 20,000 yuan, about 3 yuan, each rivet, can cause like this holding the manufacturing cost of door high, and riveted joint efficiency is low.
Summary of the invention
For the problems referred to above, the object of this invention is to provide that a kind of production efficiency is high, the end door of the concave-bottom double-layer carrier special flat car of good economy performance composition.
For achieving the above object, the present invention takes following technical scheme: a kind of end door composition of concave-bottom double-layer carrier special flat car, it is characterized in that: it comprises the end door that two are rotatably connected on the inner side of car body doorframe relatively, door is held to comprise one end door frame and one end door-plate described in each, described end door frame is formed by crisscross beam assembly welding, described end door frame has been evenly arranged multiple first perforate, described end door-plate is evenly arranged multiple second perforate, has been connected by plug welding between the first perforate with the second perforate described in each.
Be provided with a locking bar composition away from the position of car body doorframe connection side being positioned to hold described in each on door, locking bar composition described in two is connected by a door lock composition.
All be fastenedly connected multiple pedal composition near the side of car body doorframe being positioned to hold described in each on door frame, be positioned at described in each and hold the described beam of door frame to make by angle bar.
The diameter being positioned at the second perforate described in each on described end door-plate is 10 millimeters.
Hold described in each between door with car body doorframe and be connected by folding.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention arranges two ends door, every one end door comprises one end door frame and one end door-plate, connected by plug welding between end door frame and end door-plate, invention increases the joint efficiency between end door frame and end door-plate, economy is high.2, the present invention has been evenly arranged multiple first perforate on end door frame, end door-plate has been evenly arranged multiple second perforate, first perforate is easily alignd with the second perforate, can ensure to hold the assembly welding precision between Men Yuduan door frame, thus ensure that the precision of end door.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention includes the end door composition proposing a kind of concave-bottom double-layer carrier special flat car, it comprises a car body doorframe 1 end door 2 that be rotatably connected on the inner side of car body doorframe 1 relative to two.Every one end door 2 comprises one end door frame 21 and one end door-plate 22, wherein, end door frame 21 is formed by crisscross beam 23 assembly welding, end door frame 21 has been evenly arranged multiple perforate 24, end door-plate 22 is evenly arranged multiple perforate 25, has been connected (as shown in Figure 3) by plug welding between each perforate 24 with perforate 25.
In above-described embodiment, as shown in Figure 1, be positioned on each end door 2 away from the position of car body doorframe 1 connection side be provided with one locking bar composition 3, two locking bars composition 3 by door lock composition 4 connect, by opening or close door lock composition 4, the opening and closing of two ends door 2 can be realized.
In above-described embodiment, as shown in Figure 2, multiple pedal composition 5 is all fastenedly connected, for climbing in the side being positioned at close car body doorframe 1 on each end door frame 21.The beam 23 being positioned at every one end door frame 21 is made by angle bar.
In above-described embodiment, the diameter being positioned at each perforate 25 on end door-plate 22 is 10 millimeters, can ensure to hold door-plate 22 and the connection precision of holding door frame 21.
In above-described embodiment, every one end door 2 can be connected by folding with between car body doorframe 1.
