Body, one end of flexible mandril pass through spring pocket and are connect with sensor mounting plate by helicitic texture, and the other end of flexible mandril exists
Through-hole under the action of compressed spring across rail stock rail side is contacted with rail tongue side, the mandril that stretches, sensor peace
Loading board, spring pressure be female, close to switch can in mounting shell body Elastic Sliding, between rail tongue and rail stock rail
Angle becomes smaller, and the mandril that stretches drives close switch, inductor of the sensor mounting plate in adjustment screw close by compression, works as sense
When Ying Tiyu reaches setting position close to switch, the signal that the close-fitting state between rail switch is met the requirements is issued.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
The gap between tongue tip and stock rail can be directly detected, is not influenced by the adjustment of switch machine indication rod notch gap,
Corresponding relationship is accurate, and above-mentioned position is easily installed detector without other rail facility equipment, is conducive to design an apparatus anti-
Shield, safety device, sensor do not have long and complex connection system, and detection relationship is direct, simple, stable, by environment temperature shadow
Ring small, of simple structure and strong practicability.
Preferably, the further technical solution of the present invention is:
