Detailed Description
The utility model provides an end wall of a railway vehicle and the railway vehicle adopting the end wall, and in order to enable a person skilled in the art to better understand the technical scheme of the utility model, the technical scheme of the utility model is further described in detail below with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 1, the headwall of the railway vehicle provided by the present utility model includes a frame 100, a door frame 200, and a door opening a.
The frame 100 includes two vertical beams 101, the two vertical beams 101 are respectively disposed at two sides of a vertical center line of the end wall, and a door opening a is formed between the two vertical beams 101.
The door frame 200 is installed in the door opening a, and the inside of the door frame 200 is used for installing the end door. The door frame 200 comprises two upright posts 201, wherein the two upright posts 201 are positioned between the two upright beams 101, and the two upright posts 201 are respectively arranged at two sides of the vertical central line of the end wall. The two upright posts 201 are respectively and fixedly connected with the upright beams 101 on the same side, and can be welded.
As shown in fig. 2, the pillar 201 and the pillar 101 may be inserted into each other in the vehicle transverse direction through the insertion slot B. Specifically, a slot B may be disposed on a side of the upright 201 away from the vertical center line of the end wall, where a slot opening of the slot B faces the upright beam 101 on the same side, so as to connect the upright beams 101 on the same side, which is shown in the figure. Alternatively, a slot B may be disposed on a side of the vertical beam 101 near the vertical center line of the end wall, where the slot B is configured to face the column 201 on the same side, so as to insert the column 201 on the same side.
Before the vertical columns 201 and the vertical beams 101 are fixedly connected, the width dimension of the end door can be measured in advance, then the vertical columns 201 are transversely slid, so that the vertical beams 101 or the vertical columns 201 transversely slide in the slots B, the transverse distance between the two vertical columns 201 is adjusted, the actual width dimension of the end door is adapted, and the vertical columns 201 and the vertical beams 101 are fixedly connected together after the adjustment is completed.
The end wall can avoid the problem that the end door cannot be assembled between the two upright posts 201 or the gap between the assembled end door and the upright posts 201 is large because the transverse distance between the two upright posts 201 and the actual width dimension of the end door are greatly different, so that the assembling speed and the assembling quality can be improved.
As shown in fig. 1, the frame 100 further includes an upper beam 102 connected between the two upright beams 101, and a door opening a is formed below the upper beam 102. The door frame 200 further includes an upper cross post 202 connected between the two upright posts 201, and the upper cross post 202 is fixedly connected to the upper cross beam 102, specifically, can be welded.
As shown in fig. 4, the upper cross-post 202 and the upper cross-beam 102 may be plugged into each other in the vehicle vertical direction through a slot B. Specifically, a slot B may be disposed on the upper side of the upper beam 202, where a slot of the slot B faces the upper beam 102, so as to connect the upper beam 102. Alternatively, a slot B may be provided on the lower side of the upper beam 102, with the slot B facing the upper beam 202 to insert the upper beam 202.
Before the upper cross beam 202 and the upper cross beam 102 are fixedly connected, the height of the end door can be measured in advance, then the upper cross beam 202 is vertically slid, so that the upper cross beam 102 or the upper cross beam 202 vertically slides in the slot B, the height position of the upper cross beam 202 is adjusted, the actual height of the end door is adapted, and the upper cross beam 202 and the upper cross beam 102 are fixedly connected together after being adjusted in place. In this way, the problem that the end door cannot be assembled below the upper cross beam 202 or the gap between the end door and the upper cross beam 202 is large after the assembly due to the large difference between the height position of the upper cross beam 202 and the actual height dimension of the end door can be avoided, so that the assembly speed and the assembly quality can be further improved.
As shown in fig. 1, the frame 100 further comprises two corner post beams 103 and a top transverse beam 104. Two corner post beams 103 are arranged on two sides of the vertical center line of the end wall, and two ends of the top transverse bent beam 104 are respectively connected with the top ends of the two corner post beams 103. A top transverse beam 104 is located above the upper beam 102. The two upright beams 101 are located between two corner post beams 103. In the application state, the side walls on both sides of the vehicle are respectively connected with two corner post beams 103 of the end wall, and the ceiling of the vehicle is connected with a top transverse bent beam 104
As in fig. 1, the headwall also includes wall panels. The wallboard comprises two side wallboards 300 which are respectively arranged on two sides of the vertical central line of the end wall, the two side wallboards 300 are fixedly connected between the corner column beams 103 and the vertical beams 101 on the same side, and the top is fixedly connected with the top transverse bent beam 104.
The wall panels may also include a top wall panel 400, the top wall panel 400 being fixedly connected between the two upright beams 101 and also fixedly connected between the upper cross beam 102 and the top transverse camber beam 104.
Specifically, as shown in fig. 2-4, a side of the top transverse bent beam 104, the corner post beam 103 and the vertical beam 101, which are connected with the wallboard, may be provided with a wallboard bracket C extending towards the wallboard, and after the assembly, the wallboard bracket C is attached to the surface of the wallboard. When assembled, the wallboard bracket arm C can play a role in supporting the wallboard to pre-position the wallboard, and can also provide a connection foundation for the wallboard.
Specifically, as shown in fig. 4, a ceiling bracket E extending toward the ceiling is provided on the side of the roof side of the vehicle roof to which the roof side cross beam 104 is attached, and the ceiling bracket E is attached to the ceiling surface after assembly. When assembled, the ceiling bracket arm E can play a role of supporting the ceiling to fix the ceiling, and can also provide a connection foundation for the ceiling.
Specifically, as shown in fig. 4, a side wall bracket D extending toward the side wall is disposed on a side of the corner post beam 103 connected to the side wall of the vehicle, and after the assembly, the side wall bracket D is attached to the surface of the side wall. During assembly, the side wall supporting arm D can play a role in supporting the side wall to preset the side wall, and can also provide a connection foundation for the side wall.
Specifically, the wallboard can be made of aluminum honeycomb material, carbon fiber composite material or foam aluminum plate material. The wallboard not only can meet the strength requirement, but also has light weight and good sound insulation effect.
If the wall panel is made of aluminum honeycomb or foamed aluminum, the wall panel and the frame 100 may be welded and fixed. If the wallboard is made of carbon fiber composite, the wallboard and the frame 100 may be riveted.
The railway vehicle provided by the utility model can adopt the end wall on only one side or a plurality of side end walls, and can also adopt the end wall on all side end walls.
The foregoing has outlined rather broadly the principles and embodiments of the present utility model in order that the detailed description of the utility model may be better understood, and in order that the present utility model may be better understood. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the utility model can be made without departing from the principles of the utility model and these modifications and adaptations are intended to be within the scope of the utility model as defined in the following claims.
