Description

Technical Field

[0001] The utility model relates to the technical field of railway transportation equipment, and particularly to a roof cover observation window and a locomotive. Background Art

[0002] A roof cover observation window is usually installed on the top of a railway locomotive, which is convenient for staff to observe the external environment. In order to prevent water from entering the roof cover observation window, a rubber seal is usually provided at the connection between the roof cover observation window and the car body for sealing. However, in a high-temperature environment, the rubber seal is prone to aging. Moreover, during the running of the locomotive, the rubber seal is affected by the air negative pressure generated inside and outside the car, resulting in a weakened sealing effect. This easily leads to water leakage at the connection between the roof cover observation window and the car body.

[0003] That is to say, there is a problem of water leakage at the connection between the roof cover observation window and the car body in the prior art. Summary of the Utility Model

[0089] Embodiment Four

[0090] The present utility model also provides an installation and testing method for the bottom of the roof cover observation window. This installation and testing method is used to test and install the roof cover observation window, and the specific steps are as follows:

[0091] First, complete the assembly of the roof cover observation window, specifically including the connection of the bottom connection assembly, the sealed weldment to the vehicle body.

[0092] Secondly, surround the outer periphery of the bottom connection assembly with a fence;

[0093] Then, inject water between the fence and the bottom connection assembly.

[0094] It should be noted that inject enough deep water within the fence, the water exceeds the welding seam, and conduct a leak test. The welded area should not leak water for more than 3 hours after the water test.

[0095] After that, touch up the paint on the welded area. First, clean the surface, then apply putty according to the process, apply primer, and finally apply topcoat. The paint color should be the same as that of the roof.

[0096] Finally, install the glass onto the observation window window frame (within the annular counterbore) by bonding. The flange counterbore of the bonding frame is an internal counterbore method. After the glass is bonded, check whether the glass surface is flush with the window. If not, the installation position of the glass needs to be adjusted.

[0097] It should be noted that the above installation and testing environment is as follows:

[0098] Both welding and bonding are special processes, which have high requirements for their operation processes and working environments. Especially for the bonding process, the working environment requires constant temperature and humidity, preferably around 20°C, relatively clean surroundings, no dust operation. After bonding, the adhesive needs 48 hours to initially cure before the vehicle can move. It is recommended that the construction site be in the depot, and air source, water source, power supply (AC380V), overhead crane, etc. need to be provided. The operation time is 3 days. Due to the large shape of the observation window, the section side needs to specify the area for handling the scrapped observation window to be disassembled by itself.

[0099] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
