Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door control, and more specifically, to a rail vehicle door. Background Art
[0002] Railcars are the main means of transportation for railway equipment maintenance, overhaul, infrastructure and other construction departments to perform tasks. As a type of railcar, overhead contact network operation vehicles are mainly used for overhead contact network inspection and maintenance operations. Their doors are usually installed on the metal railings on both sides of the railcar as door frames. Usually, protective panels are set on the lower side of the metal railings for protection and reinforcement to prevent items on the car from falling onto the track and causing safety hazards. When the installation position of the railcar door conflicts with the height of the protective panel, it is necessary to destroy part of the protective panel at the door frame or modify the hinge installation position of the railcar door for installation to ensure that the bottom height of the installed railcar door matches the floor of the railcar to avoid excessive gaps at the bottom of the railcar door, which may cause items to fall onto the track and cause safety hazards. Therefore, a railcar door suitable for different protective panel heights is needed, which can be installed without destroying the original protective panel or modifying the hinge of the railcar door.
[0003] The utility model patent with patent application number CN221032038U discloses an electric control door for a rail vehicle, including a railing, a door hinged on one side of the railing, a door buckle, an electromagnetic lock, an LED display, and an electric control mechanism connected to the other side of the railing. The utility model manages the opening or closing authority of the door through the electric control mechanism, and synchronously displays the current state of the door through the LED display, eliminating the safety hazard of drivers and passengers getting on and off the rail vehicle when there is a car on the adjacent line, strengthening the safety protection of the rail vehicle access control, and improving safety and facilitating management and control. However, this device cannot be adapted and installed with different protective panel heights. Utility Model Content

[0029] The blocking piece 4 is arranged at different heights on the lower side of the door body 2 through a fixing member to block the gap between the door body 2 and the floor of the rail vehicle.
[0030] In practical applications, two oppositely arranged railings 1 form a door opening for installing a railcar door in space. An installation part 6 is fixed on one side railing 1, and a door locking fitting 7 cooperating with a door lock 3 is provided on the other side railing 1; the baffle 4 is fixed to the side surface of the door body 2. After the door body 2 is installed, the baffle 4 is adjusted to a suitable position and fixed to the side surface of the door body 2, so that the bottom height of the railcar door matches the floor of the railcar.
[0031] Working principle: After the door body 2 is installed, the baffle 4 is adjusted to a suitable position and fixed to the side surface of the door body 2, so that the bottom height of the railcar door matches the floor of the railcar.
[0032] By providing the baffle 4 to block and adjust the gap below the door, it is avoided that the items inside the door fall outside the vehicle. Without damaging the original protective apron 11 and other devices, it is applicable to the installation of railcar doors with different heights of the protective apron 11, improving the adaptability of the railcar door and avoiding damaging the protective apron 11, thus reducing the installation difficulty of the railcar door.
[0033] Embodiment 2
[0034] This Embodiment 2, as a preferred embodiment of the present utility model, the specific structure is as Figure 3 shown, and the following improvements are disclosed on the basis of Embodiment 1: The fixing member is configured as a bolt;
[0035] The baffle 4 is provided with a plurality of longitudinally extending strip-shaped holes 41;
[0036] At the position corresponding to the strip-shaped holes 41 on the door body 2, there are screw holes 24 cooperating with the bolts.
[0037] In practical applications, three longitudinally extending strip-shaped holes 41 are uniformly arranged on the baffle 4, and screw holes 24 are provided at the positions corresponding to the strip-shaped holes 41 on the door body 2. After the door body 2 is installed, the baffle 4 is adjusted to an appropriate height to block the gap between the door body 2 and the floor of the railcar, and the position of the baffle 4 is fixed by using a bolt as the fixing member.
