Description

Technical Field

[0001] The utility model relates to a device used in the field of rail transportation doors to ensure that a train can run when a door is in an open state. Background Art

[0002] Rail transit vehicles (non-driverless trains) are equipped with a driver's cab and driver's cab doors on both sides to meet the daily needs of staff entering and exiting the train driver's cab.

[0003] Usually, after the vehicle arrives at the station, the train driver can walk out of the driver's door and observe the safety of the passengers on the platform when the vehicle is stationary. When the vehicle leaves, the driver needs to return to the driver's cab and close the door before the vehicle can leave. At this time, the driver can only judge the safety status of the passengers on the platform by observing the reflector outside the driver's cab or the external monitoring of the train.

[0004] Disadvantages and shortcomings:

[0005] 1. In some special situations, there are blind spots when observing from inside the driver's cab through the reflector and external monitoring, and potential safety risks on the platform cannot be discovered in time. If the train is in motion, the driver's cab door can remain open, allowing the train driver to better observe the safety conditions when leaving / entering the platform.

[0006] 2. Compared with the locked state, the load-bearing capacity of the driver's cab doors in the existing market is relatively weak when the doors are open. They cannot withstand large loads, including those at the entrance of a tunnel, the air pressure generated by the intersection of trains on the opposite side, and the vibration generated on the track. Therefore, it is impossible to open the doors and drive under special circumstances. Utility Model Content

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a device that satisfies the needs of train operation when the doors are open.

[0008] A technical solution to achieve the above object is: a device for meeting the requirements of train operation when the door is open, comprising a door, an electromagnet attraction device and a door leaf limit support assembly;

[0009] The electromagnetic attraction device is installed on the top of the door leaf and includes an armature, an armature track and an electromagnet. The armature is set on the armature track and connected to the door leaf. It can slide along the armature track when the door leaf is opened and closed. An electromagnet is set at the end of the armature track. When the door leaf is opened to the maximum position, the armature and the electromagnet are attached and attracted;

[0010] The door leaf limit support assembly includes a door structure and a door frame structure. The door structure is fixed to one side of the door leaf, and the door frame structure is fixed to the vehicle body. When the door leaf is opened to the maximum position, the door structure and the door frame structure are connected to each other to limit and support the door leaf.

[0011] Furthermore, the door structure includes a door leaf supporting roller and a roller support, the roller support is fixed to the door leaf by a fastener, and the door leaf supporting roller is connected to the roller support by a connecting piece; the door frame structure includes a roller retaining support fixed to the vehicle body, and an inward-locking roller slide is provided on the roller retaining support; when the door leaf is opened, the door leaf supporting roller is clipped into the roller slide.

[0012] Furthermore, a friction-increasing pad layer is laid on the inner wall of the roller slideway.

[0013] Furthermore, the friction-increasing pad layer is made of rubber.

[0014] Furthermore, the armature is a circular ring structure sleeved on the armature track, and the electromagnet is a cylindrical structure with the same radius as the armature.

[0015] Furthermore, the electromagnet is electrically connected to the opening and closing system of the door leaf.

[0016] The advantages of the present invention are:

[0017] Under certain operating conditions, the train driver's cab door can be left open while the train is moving. This allows the driver to fully monitor the safety of passengers on the platform. Furthermore, the door can withstand the vibrations and pressure loads generated by the train's movement, ensuring reliable door opening during travel. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 This is a schematic diagram of a device for meeting train operation requirements when the door is open in the utility model. DETAILED DESCRIPTION

[0020] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:

[0021] See also Figures 1 to 2 The utility model provides a device that meets the requirements of train operation when the door is open.

[0022] The vehicle door includes an electromagnet attraction device and a door leaf limit support assembly.

[0023] The electromagnetic attraction device is mounted on the top of the door leaf and consists of an armature 1, an armature track 2, and an electromagnet 3. The armature 1 is mounted on the armature track and connected to the door leaf, sliding along the armature track 2 when the door leaf opens and closes. An electromagnet 3 is located at the end of the armature track. When the door leaf is fully opened, the armature 1 and electromagnet 3 come into contact and attract each other.

[0024] Specifically, the armature 1 is a circular ring structure sleeved on the armature track 2 , and the electromagnet 3 is a cylindrical structure having the same radius as that of the armature 1 .

[0025] Specifically, the electromagnet 3 is electrically connected to the opening and closing system of the door leaf, receives the opening and closing signal of the door leaf, is activated when opening, and is deactivated when closing.

[0026] The door leaf limiting support assembly includes a door structure and a door frame structure.

[0027] Specifically, the door structure includes a door leaf support roller 4 and a roller support 5. The roller support 5 is secured to the door leaf via fasteners, and the door leaf support roller 4 is connected to the roller support via connectors. The door frame structure includes a roller retaining support 6 secured to the vehicle body. An inwardly locking roller track is provided on the roller retaining support 6. When the door leaf is opened, the door leaf support roller 4 engages the roller track.

[0028] Furthermore, a friction-increasing pad layer is laid on the inner wall of the roller slideway.

[0029] Preferably, the friction-increasing pad layer is made of rubber.

[0030] The utility model is a device that meets the requirements of train operation when the car door is in the open state. With the addition of the device of the utility model, when the car door is fully opened, the door leaf can withstand the three-directional loads formed under the train operation condition in the fully opened state, namely the horizontal, longitudinal and vertical directions.

[0031] When in use, the driver can use the system to execute the door opening command normally. After the door is fully opened:

[0032] 1. In the electromagnet attraction device, after the armature contacts and fits with the electromagnet, the electromagnet is activated, so that the door leaf remains stably in the open position, forming a lateral support.

[0033] 2. The door leaf support rollers are embedded in the roller retaining device to form support in the longitudinal and front-to-back directions, so that the door leaf can withstand the positive and negative pressure, vibration and other working conditions that may occur during train operation when the door is fully opened.

[0034] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
