Description

Technical Field

[0001] This invention relates to the field of rail vehicle manufacturing technology, and in particular to an installation method between a vertical cover plate and a side wall plate, as well as between a vertical cover plate and an end wall. Background Technology

[0002] With the continuous development of rail transit, people have put forward higher requirements for the comfort and aesthetics of rail vehicles. As an important interior component of the vehicle, how to ensure the correctness and aesthetics of the installation of the vertical cover panel to meet the requirements of the owner is the focus of the process work.

[0003] In the interior installation of rail vehicles, uniform gaps between the vertical cover panels and the side wall panels are required. The specific installation structure involves installing the vertical cover panels first, followed by the side wall panels, with the left and right sides of the side wall panels secured to the vertical cover panels via fasteners. However, due to tolerances in the car body window openings, window installation, and the materials used in the side wall panels, uneven gaps between the side wall panels and the left and right vertical cover panels after installation occur. If the vertical cover panels are installed strictly according to the basic dimensions in the installation drawings, the uneven gaps require repeated disassembly and reassembly of the vertical cover panels for adjustment, which is time-consuming, labor-intensive, and results in low assembly efficiency.

[0004] The existing technology uses a modular structure that integrates the side wall frame, side wall panel and vertical cover panel together. This ensures that the gap between the side wall panel and the vertical cover panel is uniform during installation. However, since the position of the car door is fixed, if the position of the car window opening deviates significantly from the design position, there may be insufficient installation space between the car window and the car door, making it impossible to install the assembled modular structure.

[0005] Therefore, how to overcome the defects of large rework and construction difficulties caused by the need to disassemble and assemble the vertical cover during the installation of the side wall panels, and how to ensure that the vertical cover and the side wall panels have sufficient installation space for smooth installation, are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to address the defects and deficiencies in the prior art by providing an installation method for the vertical cover panel and the side wall panel, as well as the vertical cover panel and the end wall. This method overcomes the drawbacks of the large amount of rework and construction difficulties caused by the need to disassemble and assemble the vertical cover panel during the side wall panel installation process, and ensures that the vertical cover panel and the side wall panel have sufficient installation space for smooth installation.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] This invention provides a method for installing a vertical cover panel and a side wall panel, comprising the following:

[0009] S1. The upright cover is pre-installed at the position of the basic design size, and the pre-installed upright cover can move left and right along the length of the vehicle.

[0010] Among them, the vertical cover plates are spaced apart along the length of the vehicle, and the distance between the vertical cover plates located on both sides of the side wall plate when they are in the basic design size position along the length of the vehicle is L1, and the length of the side wall plate is L2, where L1≥L2.

[0011] S2. Install side wall panels in the area between adjacent vertical panels in the window area;

[0012] S3. Based on the actual distances between the side wall panel and the left vertical cover panel, and between the side wall panel and the right vertical cover panel, adjust the position of one of the vertical cover panels within the installation tolerance range to reduce the difference between the distance L4 between the left vertical cover panel and the side wall panel and the distance L5 between the right vertical cover panel and the side wall panel. After the adjustment is completed, fix the position of the vertical cover panel completely.

[0013] Preferably, in S3, starting from the basic design dimensions of the upright cover plate, the upright cover plate on both sides of the side wall plate with the larger distance from the side wall plate is moved closer to the side wall plate to reduce the distance between the upright cover plate and the side wall plate.

[0014] Preferably, the moving distance of the upright cover plate in S3 is not greater than the maximum installation tolerance of the upright cover plate, and the maximum installation tolerance of each upright cover plate is equal.

[0015] Preferably, in S3, when the difference between L4 and L5 is greater than or equal to the maximum allowable tolerance when installing the upright cover plate, the moving distance of the upright cover plate is the maximum allowable tolerance when installing the upright cover plate;

[0016] When the difference between L4 and L5 is less than the maximum allowable tolerance when installing the upright cover, the moving distance of the upright cover is the difference between L4 and L5.

[0017] Preferably, the upright cover plate is connected to the vehicle frame by bolts and nuts, and the bolt mounting holes on the vehicle frame and / or the bolt mounting holes on the upright cover plate are oblong holes, wherein the line connecting the two centers of one of the oblong holes is parallel to the direction of movement of the upright cover plate.

[0018] Preferably, when installing the side wall panel in S2, first adjust the window of the side wall panel to be aligned with the left and right sides of the vehicle window, and then fix the side wall panel.

[0019] Preferably, after the side wall panel is installed in S2, the relative position between the cover plate and the side wall panel is fixed by the connector.

[0020] Preferably, the connector is a hook and loop fastener.

[0021] Preferably, a door is provided on the side of the upright cover away from the side wall panel. The distance between the upright covers on the left and right sides of the door is H. The distance between the left upright cover and the longitudinal axis of the door is H1, and the distance between the right upright cover and the longitudinal axis of the door is H2. H1 = H2 = H / 2. This position is the basic design dimension position of the upright cover.

[0022] The present invention also provides a method for installing a rail vehicle's vertical cover plate and an end wall, comprising the following:

[0023] a. First, install the end wall at the designed dimensions;

[0024] b. Then install the vertical cover plate, and ensure that the vertical cover plate is installed in close contact with the end wall.

[0025] The present invention achieves the following technical effects compared to the prior art:

[0026] This invention achieves the goal of adjusting the position of the upright cover plate without disassembling it, thereby reducing the difference in distance between the side wall plate and the upright cover plates on both sides. This overcomes the drawbacks of large rework and difficult construction caused by the need to disassemble and assemble the upright cover plate during side wall plate installation, simplifies the side wall plate installation steps, and improves installation efficiency. Furthermore, it ensures that both the upright cover plate and the side wall plate have sufficient installation space for smooth installation. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4 As shown, the present invention provides an installation method between a vertical cover panel and a side wall panel, comprising the following:

[0036] S1. The upright cover plate 1 is pre-installed at the position of the basic design size, and the pre-installed upright cover plate 1 can move left and right along the length of the vehicle.

[0037] The upright cover 1 is spaced apart along the length of the vehicle. The distance between the upright cover 1 on both sides of the side wall panel 2 when they are in the basic design size position is L1, and the length of the side wall panel 2 is L2, where L1≥L2, so that the area between the two upright cover 1 can meet the installation requirements of the side wall panel 2 and avoid the problem that the side wall panel 2 cannot be installed due to insufficient space.

[0038] The pre-installed upright cover 1 can move left and right along the length of the vehicle, allowing the distance between the side wall panel 2 and the upright cover 1 to be adjusted without disassembling the upright cover 1. Compared with the existing technology that requires disassembling the upright cover 1 first and then adjusting the distance between the upright cover 1 and the side wall panel 2, this reduces the number of operation steps, improves the operation efficiency, and avoids damage to parts during disassembly, reducing unnecessary losses. In addition, when in the basic design size position, the distance L1 between the two upright cover panels 1 is greater than the length L2 of the side wall panel 2, which also ensures that the side wall panel 2 has enough installation space for its smooth installation.

[0039] S2. Install side wall panels 2 in the area between adjacent vertical cover panels 1 (i.e., vertical cover panels 1 on the left and right sides of window 8) in the window area;

[0040] S3. Based on the actual distances between the side wall panel 2 and the left vertical cover panel 1, and between the side wall panel 2 and the right vertical cover panel 1, adjust the position of one of the vertical cover panels 1 within the installation tolerance range to reduce the difference between the distance L4 between the left vertical cover panel 1 and the side wall panel 2 and the distance L5 between the right vertical cover panel 1 and the side wall panel 2. After the adjustment is completed, fix the position of the vertical cover panel 1 completely.

[0041] If the distance L4 between the left-side cover panel 1 and the side wall panel 2 is greater than the distance L5 between the right-side cover panel 1 and the side wall panel 2, one of the following methods can be used to reduce the difference between L4 and L5: Method 1: Move the left-side cover panel 1 to the right to reduce the distance between the left-side cover panel 1 and the side wall panel 2, i.e., decrease L4 to make it closer to L5; Method 2: Move the right-side cover panel 1 to the right to increase the distance between the right-side cover panel 1 and the side wall panel 2, i.e., increase L5 to make it closer to L4. Since Method 2 results in a larger gap between the cover panel 1 and the side wall panel 2, which is unsightly, this application prefers to use Method 1 to adjust the cover panel 1. Similarly, if the distance L4 between the left upright cover plate 1 and the side wall plate 2 is less than the distance L5 between the right upright cover plate 1 and the side wall plate 2, then this application preferably moves the right upright cover plate 1 to the left to reduce the distance between the right upright cover plate 1 and the side wall plate 2. That is, this application preferably adjusts the installation position of the upright cover plate 1 by taking the basic design size position of the upright cover plate 1 as the starting point and moving the one of the upright cover plates 1 located on both sides of the side wall plate 2 with the larger distance to the side wall plate 2 towards the side closer to the side wall plate 2.

[0042] The maximum tolerance for the distance between two adjacent vertical panels 1 in the door area (i.e., the vertical panels 1 located on the left and right sides of the door 9) is set to h. Then the maximum installation tolerance of the left vertical panel 1 is h / 2, and the maximum installation tolerance of the right vertical panel 1 is h / 2. That is, the maximum installation tolerance of each vertical panel 1 is set to h / 2. Since the vertical panel 1 only moves towards the side wall panel 2 and not towards the side of the design basic size position, the installation tolerance of the vertical panel 1 is (0, h / 2), and the tolerance for the distance between two adjacent vertical panels 1 in the door area is (0, h).

[0043] If L4 > L5 and L4 - L5 ≥ h / 2, then move the left side cover plate 1 to the right by h / 2, that is, move the left side cover plate 1 to its limit installation position, thereby reducing the difference between L4 and L5; similarly, if L5 > L4 and L5 - L4 ≥ h / 2, then move the right side cover plate 1 to the left by h / 2, that is, move the right side cover plate 1 to its limit installation position, thereby reducing the difference between L5 and L4.

[0044] If L4 > L5 and L4 - L5 < h / 2, then move the left-side cover plate 1 to the right by the difference between L4 and L5, so that the distance between the left-side cover plate 1 and the side wall plate 2 is equal to the distance between the right-side cover plate 1 and the side wall plate 2 after the movement. Similarly, if L5 > L4 and L5 - L4 < h / 2, then move the right-side cover plate 1 to the left by the difference between L5 and L4, so that the distance between the left-side cover plate 1 and the side wall plate 2 is equal to the distance between the right-side cover plate 1 and the side wall plate 2 after the movement. In practice, the extreme installation positions of the left-side and right-side cover plates 1 can be marked on the floor with a marker to quickly determine the movement method of the cover plates 1.

[0045] The connection between the upright cover plate 1 and the vehicle body frame can be a combination of sliders and fasteners such as screws / clips. During pre-assembly, only the slider is inserted into the groove, without tightening the screws / clips, ensuring the upright cover plate 1 does not detach from the vehicle body frame but can move left and right along the vehicle length. Other connection methods can also be used. In a preferred embodiment, one end of the upright cover plate 1 is connected to the door sealing frame 5 via bolts 3 and clip nuts, and the other end is connected to the vehicle body side wall 6 via bolts 3 and nuts 4. The bolt mounting holes on the door sealing frame 5 and the vehicle body side wall 6, and / or the bolt mounting holes on the upright cover plate 1, are oblong holes. The line connecting the two centers of one of the oblong holes is related to the movement of the upright cover plate 1. The directions are parallel, that is, the line connecting the two centers in one of the oblong holes is parallel to the length direction of the vehicle. When pre-installing the upright cover plate 1, the nut 4 is pre-tightened on the bolt 3, but the nut 4 is not tightened, so that the upright cover plate 1 can move left and right along the length direction of the vehicle. Preferably, the bolt mounting holes of the upright cover plate 1 at the mounting point of the door sealing frame 5 are oblong holes in the left and right directions, the bolt mounting holes on the door sealing frame 5 are oblong holes in the up and down directions, and the bolt mounting holes of the upright cover plate 1 at the mounting point of the side wall 6 of the vehicle body are oblong holes in the up and down directions. The side wall 6 of the vehicle body is provided with a sliding groove, and a slider is provided in the sliding groove. The slider can slide left and right along the sliding groove. The bolt passes through the slider and moves synchronously with the slider, so that the upright cover plate 1 can move up and down and also move left and right.

[0046] To prevent the position of the upright cover 1 from changing when adjusting the distance between the upright cover 1 and the side wall panel 2, this application preferably installs the side wall panel 2 and then fixes the relative position between the side wall panel 2 and the upright cover 1 using a connector 7. As a preferred embodiment of this application, the connector 7 is a latch. Other structures that prevent the relative position between the side wall panel 2 and the upright cover 1 from changing are also within the scope of protection of this application. After temporarily fixing the positions of the side wall panel 2 and the upright cover 1 using the connector 7, first measure the distance L4 between the left upright cover 1 and the side wall panel 2, and the distance L5 between the right upright cover 1 and the side wall panel 2. Then, open the latch and adjust the position of the upright cover according to the above method. After adjustment, tighten the latch. The distance between the upright cover 1 and the side wall panel 2 can be measured using instruments such as laser rangefinders and ultrasonic radar rangefinders, or using measuring tools such as vernier calipers and rulers. In this application, it is preferred to use a steel ruler to measure the distance between the upright cover 1 and the side wall panel 2.

[0047] When installing the side wall panel 2 in S2, first adjust the window 8 of the side wall panel 2 to be aligned with the left and right sides of the vehicle window, so that the exposed screen printing width on the left and right sides of the vehicle window is consistent, and then fix the side wall panel 2 to reduce the installation deviation of the side wall panel 2.

[0048] The method for determining the basic design dimensions and position of the upright cover plate 1 in S1 is as follows: A door 9 is provided on the side of the upright cover plate 1 away from the side wall plate 2. The distance between the upright cover plates 1 on the left and right sides of the door 9 is H. The distance between the left upright cover plate 1 and the longitudinal axis of the door 9 is H1, and the distance between the right upright cover plate 1 and the longitudinal axis of the door 9 is H2. H1 = H2 = H / 2. This position is used as the basic design dimensions and position of the upright cover plate 1. That is, the left and right upright cover plates 1 are first installed with the longitudinal axis of the door 9 as the reference. Then, the position of a certain upright cover plate 1 is adjusted according to the actual distance between the upright cover plate 1 and the side wall plate 2 to determine the final installation position of the upright cover plate 1. The specific method for determining the basic dimensions and positions of the upright panel 1 is as follows: First, find the upper center point of the car door 9 based on the spacing of the upper door pillars of the car door 9, and find the lower center point of the car door 9 based on the spacing of the lower door pillars of the car door 9. Mark the two center points with a marker. Then, place an upright panel 1 on each of the left and right sides of the car door 9. Adjust the distance between the upper part of the left upright panel 1 and the upper center point of the car door 9 to H / 2, and the distance between the upper part of the right upright panel 1 and the upper center point of the car door 9 to H / 2. Adjust the distance between the lower part of the left upright panel 1 and the lower center point of the car door 9 to H / 2, and the distance between the lower part of the right upright panel 1 and the lower center point of the car door 9 to H / 2. After adjustment, pre-tighten the left and right upright panels 1.

[0049] The present invention also provides an installation method between the upright cover plate 1 and the end wall 10, comprising the following:

[0050] a. First, install end wall 10 in the designed position;

[0051] The design position of end wall 10 is the basic dimension H / 2 of the distance between the vertical cover plate 1 and the center line of the door, plus the width dimension of the vertical cover plate itself (the length dimension of a single vertical cover plate in the vehicle length direction) L. 立罩板 The sum of these values ​​gives the installation tolerance of end wall 10 as (0, h / 2), meaning that end wall 10 can move away from vertical cover plate 1 but cannot move towards vertical cover plate 1, and the maximum movement is h / 2.

[0052] b. Then install the vertical cover plate 1 and make the vertical cover plate 1 fit tightly against the end wall 10 so that the vertical cover plate 1 meets the design size requirements after installation and improves the aesthetics of the interior decoration.

[0053] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
