Description

Technical Field

[0001] The utility model relates to the field of rail transit trains, and particularly relates to a stop valve device for rail trains. Background Art

[0002] To facilitate passengers getting on and off the train, a pedal device is provided at the train entrance door for passengers to pass through. The flip pedal is a relatively common type among them, which is linked with the door system: when the door opens, the flip pedal flips out synchronously; when the door closes, the flip pedal retracts synchronously.

[0003] Affected by the line conditions and platform information, there are individual platforms where the flip pedal does not need to be linked with the door. At this time, it is necessary to design a new structure specifically to make the flip pedal out of service to meet the usage requirements. Summary of the Utility Model

[0004] Purpose of the utility model: Aiming at the deficiencies and defects of the prior art, the utility model provides a stop valve device for rail trains. By operating a customized stop valve, the flip pedal can be linked with the door system or taken out of service, with small occupied space and simple operation, meeting the usage requirements.

[0005] Technical solution: A stop valve device for rail trains of the utility model includes a first air pipe and a second air pipe. A customized stop valve is arranged between the first air pipe and the second air pipe, and the customized stop valve is connected with a limit frame and a micro switch.

[0006] Among them, the first air pipe and the second air pipe are installed on a bracket assembly.

[0007] Among them, the first air pipe and the second air pipe are communicated with an external pedal cylinder.

[0008] Among them, the pedal cylinder is connected with the flip pedal.

[0009] Among them, the flip pedal is linked with the rail transit train door.

[0010] Among them, the customized stop valve is provided with a cam handle.

[0011] Among them, the bracket assembly is installed on the rail transit train door.

[0012] Advantageous effects: Compared with the prior art, the utility model has the following remarkable advantages: By operating the customized stop valve, the flip pedal can be linked with the door system or taken out of service, with small occupied space and simple operation, meeting the usage requirements. Description of the Drawings

[0013] Figure 1 It is a schematic structural diagram of the utility model;

[0014] Figure 2 Structural schematic diagram of the trigger state of the present utility model;

[0015] In the figure, 1 is a limit frame; 2 is the first air pipe; 3 is a customized stop valve; 4 is a microswitch; 5 is a bracket assembly; 6 is the second air pipe. Specific embodiments

[0016] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The stop valve device for a rail train of the present utility model includes the first air pipe 2 and the second air pipe 6. A customized stop valve 3 is provided between the first air pipe 2 and the second air pipe 6. The customized stop valve 3 is connected to the limit frame 1 and the microswitch 4. Among them, the first air pipe 2 and the second air pipe 6 are installed on the bracket assembly 5. The first air pipe 2 and the second air pipe 6 are connected to an external pedal cylinder. The pedal cylinder is connected to a flip pedal. The flip pedal is linked to the rail transit train door. The customized stop valve 3 is provided with a cam handle. The bracket assembly 5 is installed on the rail transit train door.

[0018] During use, under normal circumstances, the air paths of the first air pipe 2 and the second air pipe 6 are connected, and the pedal cylinder supplies air to drive the pedal surface to turn out. The flip pedal is linked to the door system: when the door is opened, the flip pedal turns out synchronously, and passengers get off through the flip pedal; after the passengers get on the train, the door closes and the flip pedal retracts synchronously. At this time, the handle of the customized stop valve 3 faces upward, and the microswitch 4 is in a fully released state and will not jump under vibrations or other conditions.

[0019] When at an individual platform, the flip pedal does not need to be linked to the door, it is necessary to manually operate the customized stop valve 3 counterclockwise. The air paths of the first air pipe 2 and the second air pipe 6 are cut off, the pedal air source is cut off, the pedal cylinder has no air, and the flip pedal is taken out of service. The cam handle of the stop valve 3 triggers the microswitch 4 to provide a signal to the door controller. The door system then responds separately to the centralized control door opening and closing signals for door opening and closing actions, and no faults will be reported.

[0020] At the same time, the stop valve device has the advantages of small occupied space (100mm×84mm×50mm) and flexible operation.
