Abstract
The utility model provides a wirerope tensioning probing apparatus and a door extractor system. The wirerope tensioning probing apparition comprises a base, an active cover, a shaft, an elastic element and a microswitch element. Leaning element of the active cover is pushed by the tensioned wirerope. When the elastic element applies elastic force to the active cover in a direction adjacent to the base, the active cover is pushed to the position far from the base by the tensioned wirerope winding to have restoration elastic force. When the wirerope is released, the restoration elastic force rotates the active cover to a regulated position to trigger the microswitch element to be connected or cut off so as to detect whether the wirerope is in the tensioned state. The door extractor system having the wirerope tensioning probing apparatus can detect abnormalities of the door during a short time rapidly and drive the motor to adjust correspondingly. Therefore, it is small force needed to rebound the door rapidly when the door descends.
