The main shaft 39 is connected with the motor shaft through a coupler 46, the motor 45 is positioned in the door leaf on one side of the main shaft, the main shaft is also provided with a capstan wheel 40, and the other end of the traction rope 5 which bypasses the guide wheel 4 and the plurality of traction guide wheels 41 is fixed on the capstan wheel. The motor drives the driving bottom wheel 48 and the winch wheel 40 to rotate in the same direction through the main shaft, and the driving bottom wheel 48 drives the bottom wheel set 23 to drive the door leaf to move on the bottom rail 25, so that the door leaf is opened and closed.
The length of the traction rope wound on the winch wheel is the same as the moving length of the door leaf.
The working principle of the invention is as follows: when the door leaf is in a closed state, each jacking wheel 13 is jacked on the middle part of the upper end surface of the inner side of the sealing rail bar 16 by the pressure of the jacking spring 10, so that the sealing rail bar is pressed and sealed in a gap between the bottom surface of the door leaf and the ground by each jacking wheel from top to bottom, and the gap between the bottom surface of the door leaf and the ground is sealed; at the moment, the traction rope on the winch wheel is completely released under the driving of the motor and the main shaft (clockwise rotation), and the end of the traction rope is fixed on the winch wheel. In the door leaf opening process, the winch wheel is driven to rotate reversely (anticlockwise rotation) by the motor and the main shaft, the traction rope is wound on the winch wheel reversely, and the driving bottom wheel 48 drives the bottom wheel group to drive the door leaf to move reversely on the bottom rail 25 along with the anticlockwise rotation of the motor shaft and the main shaft, so that the door leaf is opened. In the opening process of the door leaf, each jacking wheel 13 gradually loses jacking pressure on the sealing rail from front to back along with the backward movement of the door leaf, the upper end of the sealing rail losing the jacking pressure moves upwards or moves to the inner upper end of the door leaf along the groove of the sliding guide column by virtue of the pulling lug 9 and the pulling rope wound by the capstan wheel through pulling force, and after the door leaf is opened, the inner front side edge of the door leaf moves to the rear end of the sealing rail on the bottom wheel set and the bottom rail 25. On the contrary, each top pressure wheel 13 gradually presses the middle part of the inner upper end of the sealing rail bar from the rear slope to the front along with the closing forward movement of the door leaf, and the traction ropes wound on the winch wheel are gradually and completely discharged under the driving of the motor and the main shaft (clockwise rotation).
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
