Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning the air duct of a rail vehicle, in particular to an air duct assembly of a rail vehicle that can be cleaned from inside the vehicle. BACKGROUND

[0002] Currently, the commonly used materials for the air duct of a rail vehicle are aluminum alloy air ducts and polyurethane foam board air ducts. The aluminum alloy air ducts have thermal insulation cotton attached to the inside, which is difficult to clean due to dust accumulation. The polyurethane foam board air ducts are divided into artboard and foam board with aluminum foil on the surface. The artboard has a frosted surface and dust accumulation. Although the foam board with aluminum foil has a smooth surface and is not prone to dust accumulation, there are orifice plates inside the air duct to adjust the uniformity of air flow and edge dead angles, which will inevitably accumulate dust over time.

[0003] Due to the gauge of the rail vehicle and other factors, the space occupied by the air duct is small, and the structure is relatively flat, making it difficult to clean the dust from inside the vehicle. Typically, the maintenance method is to disassemble and clean, which is time-consuming and labor-intensive. Specifically, as shown in Figs. Figure 7 、 Figure 8 Each section of the air duct has an inspection opening at the bottom, and the inspection opening cover plate is made of aluminum plate structure and is fastened to the air duct structure by bolts. The aluminum cover plate is connected to the vehicle center side by a hinge. When cleaning, the bolts need to be removed, the aluminum cover plate is opened, and the hinge is hung on the air duct.

[0004] The existing technology has the following disadvantages: The air duct inspection opening cover plate of the existing technology is made of aluminum plate structure, which is heavy and requires high overall strength of the air duct. Reinforcing plates need to be added to support the air duct, which further increases the weight. The increase in weight is not conducive to lightweight design, and there is a risk of the middle of the air duct sinking down, which affects the installation of the interior trim.

[0005] The air duct inspection opening of the existing technology is opened at the bottom of the air duct and installed by bolts. Each section of the air duct is provided with an inspection opening, making the cleaning scheme more complex. The air duct inspection opening is opened at the bottom, which does not require disassembly of the air duct for cleaning, but the entire interior trim needs to be removed, and the 7 bolts of each section of the inspection opening need to be removed. The inspection openings are densely arranged, and the number of bolts is large, making the maintenance scheme relatively complex. SUMMARY

[0006] According to the above technical problems, a rail vehicle air duct that can be cleaned from inside the vehicle is provided, which reduces the time and labor cost of disassembling the air duct and facilitates maintenance.

[0007] The technical means adopted by the present application are as follows:

[0008] The rail vehicle air duct assembly can be cleaned from the vehicle interior, comprising a supply air port assembly arranged at a supply air port, the supply air port assembly comprising a Z-shaped baffle arranged at the supply air port, the Z-shaped baffle comprising a hinge, a rotating plate and an aluminum angle, one end of the aluminum angle being connected to one side of the air duct interior, the other end of the aluminum angle being provided with a through hole, one end of the rotating plate being connected to the other side of the air duct interior through the hinge, the other end of the rotating plate being provided with a through hole, and the rotating plate and the aluminum angle in the working state being connected through a mounting bolt installed in the through holes of the rotating plate and the aluminum angle.

[0009] Further, a wind port baffle is arranged at the wind port of the supply air port, one end of the rotating plate near the aluminum angle is provided with a folded edge portion, the folded edge portion is provided with a through hole, one end of the wind port baffle is mounted on the air duct, the other end of the wind port baffle is provided with a through hole, and the rotating plate and the wind port baffle in the working state are connected through a mounting bolt installed in the through holes of the folded edge portion and the wind port baffle.

[0010] Further, a grating plate is arranged at the wind port of the supply air port.

[0011] Further, the rail vehicle air duct assembly further comprises a return air port assembly arranged at a return air port, a maintenance opening is arranged at the side of the air duct at the return air port, the return air port assembly comprises a frame, a cover plate, a hinge and a buckle, the frame is connected to the air duct, the hinge is mounted on the aluminum frame and the cover plate on both sides, the cover plate is provided with a buckle, and the other end of the buckle is mounted on the air duct.

[0012] Further, the material of the cover plate is consistent with the material of the air duct, comprising a light foamed material, the back plate is an aluminum plate, and the frame is an aluminum frame.

[0013] Further, the frame is bonded with sealing rebound cotton.

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1. The present application only arranges a maintenance opening at the return air port, thereby reducing the number of maintenance openings and the number of connecting joints, and improving the overall safety.

[0016] 2. Since the foamed plate material is used instead of the aluminum cover plate, the weight of the air duct is reduced as a whole, which is beneficial to lightweight design.

[0017] 3. Before cleaning the air duct, only the supply air grating and the return air grating on the middle top interior need to be removed, thereby improving the space utilization rate and reducing the labor cost of maintenance.

[0018] 4. The design scheme of the movable Z-shaped baffle at the supply air port reduces the number of mounting bolts and improves the maintenance efficiency.

[0019] 5. The air return port adopts the buckle design, the stress is less than the bolt connection, and the torque size does not need to be considered during the maintenance, and the buckle is pressed to be convenient for operation. BRIEF DESCRIPTION OF DRAWINGS

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0037] like Figures 1-5 As shown, this invention discloses a rail vehicle air duct assembly that can be cleaned from inside the vehicle. As an optional embodiment 1, it includes an air outlet assembly located at the air outlet. The air outlet assembly includes a Z-shaped baffle located at the air outlet. The Z-shaped baffle includes a hinge 1, a rotating plate 2, and an angle aluminum 3. One end of the angle aluminum is connected to one side of the air duct interior; specifically, the angle aluminum is riveted to the air outlet of the air duct. The other end of the angle aluminum has a through hole. One end of the rotating plate is connected to the other side of the air duct interior via a hinge. The other end of the rotating plate also has a through hole. The rotating plate serves as a baffle between the static pressure chamber and the dynamic pressure chamber of the air duct. The rotating plate and the angle aluminum are connected in the working state by mounting bolts 5 and rivet nuts 4 installed in the through holes of the rotating plate and the angle aluminum. Specifically, the upper end of the rotating plate is fixed to the upper part of the air duct by riveting, and the lower end has an elongated hole at a corresponding position, which is then fitted with mounting bolts to match the rivet nuts.

[0038] On the basis of the above-mentioned embodiment 1, as an optional implementation 2, in order to adjust the wind speed or wind volume uniformity, a wind port baffle 8 is arranged at the wind port of the air supply port, the rotating plate is provided with a folded edge portion at one end close to the aluminum angle, the folded edge portion is provided with a through hole, one end of the wind port baffle is mounted on the air duct, the other end is provided with a through hole, and the rotating plate and the wind port baffle in the working state are connected through the mounting bolt 7 and the rivet nut 6 mounted in the folded edge portion and the wind port baffle through hole. Specifically, one end of the wind port baffle is riveted on the air duct, the other end is provided with a long hole, the rivet nut 6 is matched in position, and the mounting bolt 7 is installed. In order to facilitate installation, the rivet nut 6 at the folded edge portion needs to avoid the mounting bolt 5 on the rotating plate in the vehicle length direction.

[0039] A grille plate 9 is arranged at the wind port of the air supply port. In this embodiment, when cleaning, the grille plate 9 on the middle top interior is removed, and the air supply port assembly can be leaked out. Compared with the prior art, the disassembly mode is optimized, the entire middle top interior does not need to be removed, only the grille on the middle top interior needs to be removed, and the time and labor cost of maintenance is reduced.

[0040] The use method of the air supply port assembly of the above-mentioned embodiment 1 is as follows. When the air duct needs to be cleaned, the grille on the middle top interior is removed first, then the mounting bolt 5 is removed, the rotating plate 2 is lifted up through the flap 1, and the air duct is cleaned by inserting a dust collector or hand through the air supply port of the air duct. The "Z"-type baffle is a segmented structure, and the main air duct is through in the vehicle length direction. Therefore, only one air port of each air duct is selected as a movable "Z"-type baffle.

[0041] The use method of the air supply port assembly of the above-mentioned embodiment 2 is as follows. When the air duct needs to be cleaned, the mounting bolt 7 is removed, and then the mounting bolt 5 is removed. The air duct can be cleaned through the air port.

[0042] The above design does not use the aluminum cover plate structure in the prior art, reduces the risk of sinking due to insufficient air duct strength, and improves safety. The number of bolts is reduced, and the maintenance efficiency is improved.

[0043] The rail vehicle air duct assembly further comprises a return air port assembly arranged at the return air port. Since the sub-air duct at the return air port guides the air to both sides through the air distribution plate, the movable baffle is not used here. An inspection opening is arranged on the side surface of the air duct at the return air port. The return air port assembly comprises a frame 12, a cover plate 14, a return air port flap 10 and a buckle 11. The frame is connected with the air duct. The return air port flap is mounted on the aluminum frame and the cover plate on both sides. The cover plate is provided with a buckle, and the other end of the buckle is mounted on the air duct.

[0044] As shown in Figure 4 The wind port of the return air port is also provided with a grille plate. The grille plate of the return air port is at the bottom, and the buckle is arranged on the side surface.

[0045] The material of the cover plate is consistent with the material of the air duct, including a light foamed material 15, an aluminum plate as the back plate, and an aluminum frame. The overall weight of the air duct is relatively light, realizing the lightweight design of the air duct.

[0046] The frame is bonded with sealing rebound cotton 13 to ensure the sealing property.

[0047] When the air duct needs to be cleaned, the return air grille on the middle top interior is disassembled, the buckle on the access hole is unfastened, the cover plate is lifted up through the folding page, and the dust collector is inserted from the access hole to clean.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
