The invention provides a through channel side guard plate structure, which belongs to the technical field of railway vehicles, and comprises two mounting seats, guard plate leaves and a guide extension frame, and is characterized in that the two mounting seats are oppositely arranged at an interval and are respectively and fixedly connected with a vehicle body; the at least three guard plate leaves are all located between the two mounting seats and are sequentially arranged in a lap joint mode; the two guard plate leaves located on the two sides are hinged to the two mounting seats respectively. The guide extension frame is arranged on one side of each guard plate leaf, fixedly connected with each guard plate leaf and used for guiding each guard plate leaf to evenly slide in the advancingdirection of a vehicle. According to the through channel side guard plate structure, under the action of the guide extension frame, each guard plate leaf evenly slides relatively, and the situation that due to the fact that an individual guard plate leaf tilts by a large margin, the guard plate leaves fall off easily is avoided. Potential safety hazards generated when a vehicle passes through a curved road section are eliminated.
Description
technical field [0001] The invention belongs to the technical field of rail vehicles, and more specifically relates to a side guard plate structure of a through tunnel. Background technique [0002] The through passage is a flexible and movable part of the rail vehicle, which can adapt to the relative movement between two adjacent carriages and provide a safe and comfortable passage for passengers. The side guard plate of the tunnel is the part with the largest visible range for passengers in the tunnel, and it is also the most critical part for the tunnel to buffer the relative movement between the two carriages. The quality of the side guard structure directly affects the appearance quality of the tunnel products and Use safety features. When a rail vehicle passes through a curved road section, the side guards are prone to warping due to different displacements, posing a safety hazard of pinching passengers. Contents of the invention [0003] The purpose of the present...
