Basic functions
Display function This device can accurately display the current position of the switch.
Remote control function The remote control can remotely control the turnout from the longest distance.
Manual function: When the switch control button is pressed, the switch will change lanes.
Alarm function: When the switch fails, the switch display will emit warning lights.
Three working environment requirements
Ambient temperature ℃~+℃
b The average relative humidity of the air is not greater than (+℃
Atmospheric pressure~
The ambient noise is not Larger than
There are explosive mixtures, but there are no corrosive gases that damage the insulation layer.
Four structures
The explosion-proof cavity is welded by steel plates. The explosion-proof enclosure should comply with the regulations in B.
Fasteners should have measures to prevent automatic loosening and comply with regulations B and B.
Metal parts should be treated against rust and corrosion.
The shell should be equipped with internal and external grounding bolts and comply with The provisions of B.
The cable entry device should comply with the provisions of B and B.
The electrical clearance and creepage distance should comply with the provisions of B.
Five working principles
Driver remote control Function
When the locomotive enters the switch area, the locomotive driver can determine the current status of the switch according to the instructions on the display. If he needs to switch the switch, he can press the remote control button in the locomotive cab, and the switch will be on the switch device. Switch to the required direction under the control of the vehicle.
Brief description of the principle
When the locomotive enters the switch area, if the switch needs to be switched, the driver can press the button on the remote control, and the remote control will emit a coded After receiving the signal, the main control box processes it and outputs a control level signal to the solenoid valve. The solenoid valve controls the extension or retraction of the execution cylinder to achieve the purpose of controlling the closing or disconnection of the switch rail. At the same time, the display shows the current status of the switch.
Installation and debugging
Equipped with remote control This device is equipped with a compact fixed remote control, which can be placed in the locomotive cab where the driver can easily operate it.
Installation of the main control box The main control box is a flameproof and intrinsically safe design. It can be hung on the tunnel wall in a place where it will not be hit when in use. The installation should be firm, and the wiring should be neat, standard and easy to operate.
Installation of the display The display is intrinsically safe in design. When in use, it can be hung above the intersection of the alley and in a place where it is easy to observe without being hit. The installation should be firm.
The actuator (including the magnetic closure) should be installed firmly Fix the four anchor screws of the actuator so that it cannot move relative to the rails during operation. Ensure that the screws on the connections and terminals are tightened and not loose. The intake and exhaust pipes connected to the main control box must be kept clear and cannot be squeezed. Adjust the installation position of the proximity switch to be correct.
Debugging Connect all parts of the switch device according to the instructions, and turn on the power. One of the switch status indicator arrows on the display lights up and a number lights up at the same time. At this time, the actuator is connected. Air source, and then press the button on the remote control corresponding to the number displayed on the monitor. The switch device should be able to work normally and accurately realize the closing and separation of the switch point rail and the fixed rail.
