Problems solved by technology
[0003] However, there is a problem in the prior art that different interior components on the roof of the compartment need to be hoisted with different functional components. Connection; components such as wire slots, side roofs, and light strips need to be fixedly connected to the corresponding segmented aluminum profile suspension arms, and then each segmented aluminum profile suspension arm is connected to the corresponding vehicle via the same long aluminum profile suspension arm. Body C-shaped groove fixed connection
In this way, not only are there many interfaces, complicated installation methods, difficult to adjust the installation size, and low installation efficiency, but also increase the weight of the carriage, which is not conducive to energy saving and emission reduction

Embodiment
[0031] Such as Figure 1 to Figure 2 As shown, the method for hoisting the inner parts of the roof of the intercity EMU car in this embodiment includes the following steps:
[0032] The first step is to adopt the multifunctional built-in hanging arm profile 1:
[0033] The profile is a long profile, and the section of the profile has a hypotenuse 1-1 whose upper side is fixedly connected with the outer compartment body. The middle part extends downwards to the second hem 1-22 close to the first hem 1-21, and the ends of the first and second hems 1-21 and 1-22 away from the hypotenuse 1-1 are used for hanging The hanging light belt is fixedly connected to the first C-shaped groove 1-31 of the side roof; the hypotenuse 1-1 extends downward near the high end and extends downwards to the third hem 1-23 away from the second hem 1-22, the hypotenuse 1 -1 The connection between the middle part and the second folded edge 1-22 extends downward to the fourth folded edge 1-24 away from...

The invention relates to an intercity motor train unit car top built-in part hoisting and mounting method. The method includes: adopting a multifunctional built-in suspending arm profile; hoisting and mounting the profile on a car body; fixedly connecting a wire groove with the profile; fixedly connecting an air-conditioning air duct and a car top plate with the profile; and fixedly connecting a side top plate and a lamp strip with the profile; then the hoisting and mounting is completed. By the intercity motor train unit car top built-in part hoisting and mounting method, simultaneous mounting of various car top built-in parts can be realized, integration level is high, improvement of mounting efficiency is facilitated, and car weight is lowered.
Description
technical field [0001] The invention relates to a method for hoisting interior components of the car roof of intercity EMUs, which is suitable for highly integrated installation of the interior components of the roof of intercity EMUs. Background technique [0002] According to the applicant's understanding, the interior of the existing intercity EMU compartment is usually provided with a C-shaped groove on the car body, and a connector is used to fix the interior parts and the C-shaped groove together, such as the application number 2012206530474 authorized announcement number CN202923646U in China The utility model patent uses a T-shaped slider to cooperate with a C-shaped groove, and fixes functional components on the T-shaped slider, and then connects the functional components to the interior components. [0003] However, there is a problem in the prior art that different interior components on the roof of the compartment need to be hoisted with different functional comp...
