Abstract
An aluminum alloy door pillar for a subway car comprises a first hollow pillar body used for constituting a main door pillar body as well as a second hollow pillar body connected with a car wall plate, wherein the second hollow pillar body and the first hollow pillar body are arranged side by side and share one common side plate, one end plate of the second hollow pillar body and one end plate of the first hollow pillar body are coplanar, the other end plate of the second hollow pillar body is located in the middle of one side plate of the first hollow pillar body, a right-angle part is defined by the end plate and the side plate, the width of the other end plate of the second hollow pillar body is matched with the thickness of the car wall plate, and a connecting bulge strip is arranged on the outer edge. According to the aluminum alloy door pillar for the subway car, the main body part adopts the hollow pillar bodies, and the cross sections are larger, so that not only can the car strength be guaranteed, but also the aluminum material can be saved, and the cost and the weight of the door pillar can be reduced; and the right-angle part and the connecting bulge strip of the profile are directly utilized, so that positioning for the wall plate and the door pillar before welding is realized, and the mounting is more convenient and faster.
Description
Technical field
The utility model relates to subway carriage, more particularly, relates to a kind of subway carriage aluminium alloy door column.
Background technology
Aluminium alloy extrusions has the plurality of advantages such as intensity is high, lightweight, good corrosion resistance, therefore in the structure design of subway carriage, has adopted a large amount of aluminium alloy extrusions.The cylindrical shell compartment surrounding with a plurality of elongated aluminium section bars is most typical aluminum alloy carriage body construction, but the compartment large-area section bar of side door incision is cut off, formed compartment compared with thin spot.In order to meet the requirement of strength in compartment, side wall outer panel (longitudinally strength beam) is widely used in this field, to improve the intensity of this thin spot.
Fig. 1 shows a kind of structure of subway carriage side wall outer panel, and Fig. 2 shows itself and being connected of cab wall.As shown in Figure 1, 2, the inserted sheet 13 that this subway carriage side wall outer panel 12 is connected with cab wall 15 in a side setting, arranges auxiliary swash plate 11 at another side.During installation, first utilize auxiliary swash plate 11 in the end of side wall outer panel 12, to weld some reinforcement gussets 14, utilize 13 pairs of side wall outer panels 12 of reinforcement gusset 14 and inserted sheet to be connected location with cab wall 15, and then be welded and fixed.
Above-mentioned side wall outer panel with wallboard welding before the location of first pegging graft, make to be easy to welding and also can guarantee welding quality.But still there is following technical matters: when mounted, need to weld some reinforcement gussets 14 with auxiliary positioning, trouble is installed.In addition, its base portion is a solid slab, and in order to meet the requirement of strength in compartment, the thickness of plate will be done greatlyr, thereby makes the cost of side wall outer panel higher, and weight is larger.
Utility model content
The purpose of this utility model is to provide a kind of subway carriage aluminium alloy door column, the above-mentioned technical matters existing to solve existing subway carriage side wall outer panel.
The technical solution adopted in the utility model is:
A subway carriage aluminium alloy door column, it comprises:
For forming the first hollow cylinder of side wall outer panel main body; And
For the second hollow cylinder being connected with cab wall, the second hollow cylinder and the first hollow cylinder are arranged side by side and have a public side plate, end plate of the second hollow cylinder and an end plate of the first hollow cylinder are coplanar, middle part and this side plate that another end plate of the second hollow cylinder is positioned at a side plate of the first hollow cylinder surround a right angle portion, and the width of described another end plate of the second hollow cylinder is suitable with the thickness of cab wall and arrange and be connected ridge in outer place.
During installation, first the end of cab wall is docked with described another end plate of the second hollow cylinder, particularly, make on the one hand the end of cab wall peg graft with the described ridge that is connected, make on the other hand the above-mentioned right angle portion laminating butt of right angle portion that cab wall sidepiece and end surround and side wall outer panel, thereby can realize quickly and easily the accurate location before cab wall welds with side wall outer panel.
In above-mentioned subway carriage aluminium alloy door column, preferably, in described the first hollow cylinder, between two end plates, the first reinforcement gusset is set.
In above-mentioned subway carriage aluminium alloy door column, preferably, in described the second hollow cylinder, between two end plates, the second reinforcement gusset is set.
Due to the base portion employing hollow cylinder of side wall outer panel, cross section is larger, not only can guarantee cabin strength, and can save aluminium, thereby can reduce costs and alleviate the weight of side wall outer panel.Meanwhile, due to the right angle portion that directly utilizes section bar itself be connected ridge and realize the location before wallboard and side wall outer panel welding, make easier for installation quick.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing a kind of subway carriage side wall outer panel;
Fig. 2 is the connection structure schematic diagram of itself and cab wall;
Fig. 3 is the structural representation of an embodiment subway carriage aluminium alloy door column;
The connection structure schematic diagram of Tu4Wei Tu3 subway carriage aluminium alloy door's column and cab wall.
The specific embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
Fig. 3 shows the structure of an embodiment subway carriage aluminium alloy door column.As shown in Figure 3, this subway carriage aluminium alloy door column comprises the first hollow cylinder 21 and the second hollow cylinder 22.The first hollow cylinder 21 is for forming the main body of side wall outer panel.The second hollow cylinder 22 is for being connected with cab wall 24.
The second hollow cylinder 22 and the first hollow cylinder 21 are arranged side by side, the public side plate that the side plate 222 of the second hollow cylinder 22 and the side plate of the first hollow cylinder 21 212 are the two.End plate 221 of the second hollow cylinder 22 and an end plate 211 of the first hollow cylinder 21 are coplanar, another end plate 223 of the second hollow cylinder 22 be positioned at the first hollow cylinder 21 a side plate 212 middle part and this side plate 212 surrounds the width of described another end plate 223 of a right angle portion 23, the second hollow cylinders 22 and the thickness of cab wall 24 is suitable and arrange and be connected ridge 224 in outer place.
Fig. 4 shows the connection structure of above-mentioned subway carriage aluminium alloy door's column and cab wall 24.With reference to Fig. 3 and Fig. 4, during installation, first the end of cab wall 24 is docked with another end plate 223 of the second hollow cylinder 22, particularly, the end that makes on the one hand cab wall 24 be connected ridge 224 grafting, make on the other hand the above-mentioned right angle portion 23 laminating butts of right angle portion that cab wall 24 sidepieces and end surround and side wall outer panel, thereby can realize quickly and easily the accurate location before cab wall 24 and side wall outer panel welding.
