For example: abnormal entering conditions (explosion, prying, unidentified invasion and the like) can be discriminated through the acceleration sensor and the angular displacement sensor, and a field image can be timely transmitted back to the monitoring center through the optical fiber network through the camera; an alarm signal (twinkling light and/or sounding) can be initiated through the alarm, so that the effect of deterring abnormal entry is achieved; the running states of the large door leaf 3 and the small door leaf 4 can be clearly seen through the indicating lamps, and escape can be guided in case of disaster; through temperature sensor, sensor to hazardous gas, the sensor of response cigarette sense, can leak natural gas and the conflagration condition carries out quick discernment warning, in time eliminates the disaster situation hidden danger that can, ensures the safety of engineering inside personnel and equipment. According to the invention, various sensors with auxiliary functions, cameras and alarms are arranged, so that the requirements of disaster prevention and invasion prevention monitoring at the hoisting opening can be met, and the functions of intelligent environment monitoring, automatic security alarm, escape guidance and the like at the hoisting opening are realized.

As shown in fig. 1 to 20, the working process of the present invention is explained in detail as follows:

and a PLC controller is operated on the man-machine interaction platform, and when the door leaf is opened, the audible and visual alarm is opened to prompt surrounding personnel to pay attention. The PLC sends a signal, and controls the first motor 21 to drive the gate lock 2 to complete the opening action after speed reduction to release the gate lock head 25; then the second motor 51 is controlled to drive the small door lock 5 to complete the rotation action after the speed is reduced, so as to release the small door lock head 55, and the lock is converted from the closed state to the open state; the lock displacement sensor returns a lock in-place signal, and the unlocking indicating lamp is lightened. The PLC controls the plug rod of the first electric push rod 71 to lift out, and the jacking large door leaf 3 turns around the connecting shaft 64 of the hinge leaf 6 to open the large door leaf 3; then the plug rod of the second electric push rod 72 is controlled to lift out, and the small jacking door leaf 4 turns around the connecting shaft 64 of the hinge leaf 6 to open the small jacking door leaf 4; the door leaf displacement sensor returns a door leaf in-place signal, the door opening indicating lamp is turned on, and the audible and visual alarm is turned off. The control flow for closing the door leaf is opposite to the control flow for opening the door leaf.

Briefly, the motion control sequence of the present invention is as follows:

when the device is started: the gate lock 2 → the small gate lock 5 → the first electric push rod 71 at the large door leaf 3 → the second electric push rod 72 at the small door leaf 4;

when closing: the second electric push rod 72 at the small door leaf 4 → the first electric push rod 71 at the large door leaf 3 → the small door latch 5 → the large door latch 2.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Thus, the embodiments disclosed above are illustrative and not exclusive in all respects. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
