[0020] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0021] like Figure 1-9 The marks in the figure are: waterproof board 1, door frame trolley 2, trapezoidal lifting frame mechanism 3, trapezoidal frame body 31, lifting motor 32, cable fixing hook 33, cable 34, first-step double-opening revolving door 4, second-step revolving door 5, third-step revolving door 6, upper bracket 7, and lower bracket 8.

[0022] Example: Figure 1-9 As shown, this embodiment specifically relates to an automatic lifting and hanging trolley for waterproof panels in tunnels, and the automatic lifting and hanging trolley includes a door frame trolley 2, a trapezoidal lifting frame mechanism 3 and three groups of symmetrically arranged revolving doors.

[0023] like Figure 2 , 3As shown, the gantry trolley 2 is in a door-shaped structure, and a wheel frame is arranged at the bottom of the two side columns. The two side columns and the top crossbeam together form a middle channel. The ladder-shaped lifting frame mechanism 3 is fixedly installed on the top of the gantry trolley 2, and should be a detachable fixed structure, such as Figure 2 , 3 As shown, the main body of the trapezoidal lifting frame mechanism 3 is a trapezoidal frame body 31, a lifting motor 32 is installed on one side of the top of the trapezoidal frame body 31, a cable fixing hook 33 is arranged on the other side of the top, and a cable 34 is connected between the cable fixing hook 33 and the lifting motor 32, that is, one end of the cable 34 is connected to the cable fixing hook 33, and the other end is wound and fixed on the rotating shaft of the lifting motor 32, and the rise and fall of the cable 34 is controlled by the forward and reverse rotation of the lifting motor 32. It should be noted that in order to realize the lifting function of the cable 34, two sets of trapezoidal frames 31 are arranged at the longitudinal ends of the gantry trolley 2, so that the two ends of the coil of the waterproof board 1 can be lifted separately.

[0024] like Figure 2 , 3 As shown, three groups of revolving doors are symmetrically arranged on the top of the gantry trolley 2, namely, a first-order double-leaf revolving door 4, a second-order revolving door 5, and a third-order revolving door 6. Among them, the first-order double-leaf revolving door 4 is arranged in the middle area of ​​the top of the gantry trolley 2 and is located directly below the trapezoidal frame 31. The opening of the first-order double-leaf revolving door 4 can form a channel for the cable 34 to lift objects, and can be opened later to spread the waterproof board 1. The second-order revolving door 5 and the third-order revolving door 6 are arranged from the inside to the outside at once, and the second-order revolving door 5 and the third-order revolving door 6 can be opened by rotating to spread the waterproof board 1 outward. It should be noted that the motor and the rotating shaft of each revolving door are arranged on the outside side.

[0025] like Figure 2 , 9 As shown, lateral supports are fixedly arranged on the outer sides of the two side supports of the gantry trolley 2, and the lateral supports include an upper support 7 and a lower support 8. The upper support 7 and the lower support 8 are respectively in the shape of triangular supports, and the gradually unfolded waterproof board 1 can be supported accordingly by the upper support 7 and the lower support 8.

[0026] like Figure 1-9 As shown, the working method for the automatic lifting and hanging trolley for waterproof panels in tunnels in this embodiment includes the following steps:

[0027] (S1) Figure 2 , 3 As shown, the installed waterproof board is automatically lifted and hung up by the trolley and moved to the starting position, the first-stage double-opening revolving door 4 is opened and unfolded, and then the lifting motor 32 is started to reverse and lower the cable 32 to the tunnel ground position.

[0028] (S2) Figure 4 , 5 As shown, the two ends of the waterproof board 1 in the rolled state are placed on the cable 32, and then the lifting motor 32 is turned on and rotated forward to lift the waterproof board 1 to a height close to the ladder frame 31 by pulling the cable 32.

[0029] (S3) Figure 5 , 6 As shown, the one-step double-opening revolving door 4 is controlled to rotate and close, and then the cable 32 is lowered again to allow the waterproof board 1 to fall on the one-step double-opening revolving door 4, and then the trapezoidal lifting frame mechanism 3 and the door frame trolley 2 are disassembled and removed.

[0030] (S4) Figure 7 As shown, the waterproof board 1 is a flexible coiled material, and each waterproof board 1 is preset to have two rolls. The first-step double-opening revolving door 4 is controlled to rotate and open, and the front end support of the first-step double-opening revolving door 4 lifts the middle area of ​​the waterproof board 1 to allow the coils on both sides to slide outward and spread.

[0031] (S5) Figure 8 As shown, when the coils on both sides of the waterproof board 1 slide onto the second-step revolving door 5, the second-step revolving door 5 is continuously controlled to rotate and open and its front end is rotated to the same height as the front end of the same-step double-leaf revolving door 4, and the coils on both sides of the waterproof board 1 continue to slide outward onto the third-step revolving door 6, as shown in FIG. Fig. 9 As shown, the three-step revolving door 6 is continued to be controlled to rotate and open, and its front end is rotated to the same height as the front end of the two-step revolving door 5, and the rolls of materials on both sides of the waterproof board 1 slide downward to the upper side brackets 7 on both sides of the door frame trolley 2, thereby realizing the automatic lifting and hanging of the waterproof board 1.

[0032] The beneficial effects of this embodiment are: the overall automatic lifting of the waterproof sheet roll can be achieved through the trapezoidal lifting frame mechanism, and the outward spreading and hanging of the waterproof sheet roll can be achieved through the three-step rotating doors arranged from the inside to the outside, with a high degree of automation.
