[0054] The installation method of the rail vehicle throughway guard plate structure of this embodiment is as follows:

[0055] S1: installing two upper mounting seats (5) and two lower mounting seats (6) at corresponding interface positions on the end surface of the vehicle body respectively;

[0056] S2: First pull the lock hook (1.5) of the upper connecting seat (1) upward to the top, and then rotate it 90 degrees so that the compression spring stopper (1.4) is buckled into the transverse groove of the upper base body (1.1);

[0057] S3: Lift the guard plate body (2) vertically, and then tilt it back to facilitate viewing of the mounting tube (2.5) of the guard plate body (2). At this time, align the mounting tubes (2.5) on both sides with the shaft ends of the guide blocks (3.3) inserted into the lower connecting seat (3);

[0058] S4: Push the inclined upper part of the guard plate body (2) to the vertical direction. At this time, the mounting shaft (2.7) of the guard plate body (2) is inserted into the waist-shaped hole of the upper base body (1.1). At this time, rotate the lock hook (1.5) 90 degrees so that the lower part of the lock hook (1.5) is inserted into the hole of the mounting shaft (2.7).

[0059] S5: To confirm whether the guard plate is installed in place, you can pull the guard plate body (2) outward to see if it is loose, or you can use your hands to push aside the wrinkles of the skirt (2.2) and reach inside to feel whether the installation shaft (2.7) is inserted in place. At this point, the guard plate structure is installed.

[0060] The method for disassembling the rail vehicle tunnel guard plate structure of this embodiment is as follows:

[0061] S1: Open it by hand: extend the folds of the skirt (2.2) to the inside, pull the lock hook (1.5) of the upper connecting seat (1) upward to the top, and then rotate it 90 degrees to make the compression spring stopper (1.4) buckle into the groove of the upper base body (1.1).

[0062] S2: Pull the upper part of the guard plate body (2) outwards, and then lift the guard plate body (2) upwards as a whole. At this point, the guard plate is removed and can be repaired and maintained (during the repair and maintenance work, the upper and lower mounting seats (5, 6) do not need to be removed).

[0063] The operating principle of the rail vehicle throughway guard plate structure of this embodiment is as follows:

[0064] (1) During stretching, the right and left guard plate profiles (2.3, 2.6) rotate around the rotation axis (4.6) to increase the width of the guard plate;

[0065] (2) During compression, the torsion spring (4.5) causes the right and left guard plate profiles (2.3, 2.6) to rotate. When the right and left guard plate profiles (2.3, 2.6) rotate to a certain position (the hole seat (4.3) touches the base), the compression continues, and the right and left guard plate profiles (2.3, 2.6) stop rotating, while the middle guard plate body (2.1) adapts to the curved motion by deforming outwards;

[0066] (3) When the vehicle body has a height difference between up and down during curved motion, the guard plate body (2) can be adjusted at any time through the tension and compression spring (4.2).

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
