6. A lifting device (1) for climbing door in building industry according to claim 3, wherein the number of racks (5) is two, the racks are symmetrically distributed on the aluminum alloy bracket guide rails (4) at two sides of the door leaf, the gears (105) are also provided with two groups, and the gears are connected to two ends of the transmission rod (104) and are respectively meshed with the two racks (5).
7. A lifting device (1) for climbing doors in the construction industry as claimed in claim 3, characterized in that the transmission rod (104) is passed through and connected at one end to an RV retarder (102) fixedly connected to the door panel assembly (2) and at the other end to a bearing housing (106) fixedly connected to the door panel assembly (2).
8. Lifting device (1) for climbing doors in the construction industry according to claim 1, characterized in that a plurality of door plate assemblies (2) are hinged in pairs, and rollers are arranged on both sides of each door plate assembly (2) so that the door plate assemblies (2) move in the aluminum alloy bracket guide rail (4) through the rollers.
9. A method of lifting a lifting device (1) for a climbing door in the construction industry according to any one of claims 1 to 8, characterized in that it comprises the steps of:
step (A): when the climbing door needs to be opened, the driving motor (101) is started to rotate positively, and rotary power is transmitted to the gear (105) through the RV reducer (102) and the coaxial transmission assembly (104), so that the gear (105) ascends along the rack (5);
step (B): in the ascending process of the gear (105), a door plate component (2) at the lowest part of the bottom ascends along the aluminum alloy bracket guide rail (4) through rollers at two sides;
step (C): when the climbing door hovers at the middle position, the driving motor (101) stops rotating, and the self-locking function of the RV reducer (102) can lock the rotation of the gear (105), so that the hovering of the climbing door is realized;
step (D): when the climbing door needs to be closed, the driving motor (101) is started to rotate reversely, and the rotation power is transmitted to the gear (105) through the RV reducer (102) and the coaxial transmission assembly (104), so that the gear (105) descends along the rack (5);
step (E): in the descending process of the gear (105), the door plate component (2) at the lowest part of the bottom descends along the aluminum alloy bracket guide rail (4) through rollers at two sides.
