Abstract
The utility model relates to an air passage connection structure of a metro vehicle, which comprises a first air passage and a second air passage, wherein flanges which correspond to each other are fixedly arranged on the side walls of the first air passage and the second air passage, the flange on the first air passage and the flange on the second air passage are fixed through a bolt for realizing the connection of the first air passage and the second air passage, and a sealing strip is clamped between the first air passage and the second air passage; and the end surfaces of the flanges are positioned on one side of the air passage connection surface. The air passage connection structure is simple and convenient to mount and operate and can improve the working efficiency; the detachment is fast and convenient during the repair and the maintenance of the vehicle; and the air passage connection structure can solve the difficult problems that the connection and the sealing of the aluminum alloy air passages are not tight and the mounting is inconvenient. The result of the analysis of the strength and the sealing property of the structure further proves that the structure can fully meet the requirements on the mounting strength and the sealing property, thereby being the safe and reliable structure. The structure can be applied in the realistic connection and the mounting of the aluminum alloy air passages of the metro vehicle, and tests and applications also prove that the structure is safe and reliable.
Description
Technical field
The utility model relates to passenger train stopping sliding door system, the connection structure in especially a kind of railcar air channel.
Background technology
The vent window of railcar is installed to adopt mostly and with fastener the vent window section bar is connected to structural mode at present.The use of a large amount of fasteners causes location difficulty, and packaging efficiency is low, is inconvenient to dismantle, and brings difficulty to maintenance maintenance, and work capacity is big, and efficient is low.
Summary of the invention
The purpose of this utility model is: at above the deficiencies in the prior art, propose the connection structure in a kind of railcar air channel.
In order to reach the above object: the connection structure in a kind of railcar air channel that the utility model provides, it comprises first air channel, second air channel, the sidewall that it is characterized in that first air channel and second air channel is fixed with flange in correspondence with each other, pass through bolt between flange on described first air channel and the flange on second air channel, realize being connected of first air channel and second air channel, accompany sealing band between described first air channel and second air channel.
In the utility model, the end face of described flange is positioned at a side of air channel joint face; Described flange riveted and fixed is on the air channel.
Before the air channel connects, flange uses rivet respectively earlier on first, second air channel main body, and sealing band is attached to earlier on second air channel, when mounted simultaneously, first air channel is plugged into place, second air channel, sealing band plays the effect of sealing and adjusting in the centre therebetween, and after grafting was good, each flange place got final product with fastener is fixing, wherein having only three faces for the rectangular aluminium alloy air channel is flanges, the top of air channel do not add bolted owing at the roof face so do not manage orchid, and be easy for installation like this.Operation order is opposite with assembling during dismounting.
The advantage of this kind structure:
Fitting operation is simple and easy, has improved work efficiency;
Dismounting is quick and convenient during the vehicle maintenance maintenance;
Solved a difficult problem poorly sealed in the connection of aluminum alloy air channel and that installation is inconvenient.
By this kind structure is carried out intensity and hermeticity analysis, the result has proved that this structure satisfies the intensity and the sealing requirements of installing fully, is a kind of safe and reliable structure.This structure is applied in the aluminum alloy air channel connection of real railcar, through overtesting and utilization proof, structural safety is reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
The connection structure in the railcar air channel of present embodiment, as shown in Figure 1, comprise first air channel 1, second air channel 2, the sidewall in first air channel 1 and second air channel 2 is fixed with in correspondence with each other flange 3,4 (in this example, the flange riveted and fixed is on the air channel), fixing between flange 3 on described first air channel 1 and the flange 4 on second air channel 2 by bolt 5, realize being connected of first air channel 1 and second air channel 2, accompany sealing band 6 between first air channel 1 and second air channel 2.
For the bonded assembly steadiness, in the present embodiment, the end face of flange 3,4 is positioned at a side of air channel joint face.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of the utility model requirement.
