[0027] See also Figure 1-6 The present invention provides a technical solution: a lifting device that is convenient for quickly grabbing the glass curtain wall, according to Figure 1 and Figure 2 As shown, a first motor 2 is installed on one side of the top of the fixed platform 1, and the output end of the first motor 2 is connected to the driving wheel 3, the driving wheel 3 is connected to the driven wheel 5 through a transmission belt 4, and a double-cylinder winding mechanism is installed inside the driven wheel 5, a support rod mechanism is symmetrically arranged on one side of the double-cylinder winding mechanism, and a fixed pulley 6 is installed on the top of the support rod mechanism, and the hoisting line 7 in the double-cylinder winding mechanism is connected to the glass curtain wall hoisting frame 8 through the fixed pulley 6.

[0028] In a further embodiment, the glass curtain wall hanging frame 8 includes a frame body, and two sets of hanging connectors are symmetrically arranged on the top of the frame body for connecting with the hanging line 7.

[0029] Specifically, a counterweight 10 is provided on a side of the fixing platform 1 away from the glass curtain wall hanging frame 8 , and a fixing leg 11 is installed on the bottom of the fixing platform 1 .

[0030] In a further embodiment, the counterweight 10 is provided to prevent the interior of the glass curtain wall hoisting frame 8 from being overweight in the later stage, thereby causing the fixing platform to tilt.

[0031] Specifically, the double-drum winding mechanism includes a first rotating rod 12, and the first rotating rod 12 is connected to the inside of the driven wheel 5. A winding drum 13 is symmetrically installed on the outside of the first rotating rod 12, and the position of the winding drum 13 matches the support rod mechanism.

[0032] Specifically, both ends of the first rotating rod 12 rotate inside the support columns 14 symmetrically arranged on the top of the fixed platform 1 , and the hoisting line 7 is wound around the outside of the winding drum 13 .

[0033] Specifically, the support rod mechanism includes a first diagonal support rod 15 and a second diagonal support rod 16.

The fixed pulley 6 is located at the connection between the top ends of the first diagonal support rod 15 and the second diagonal support rod 16. The fixed pulley 6 is vertically positioned away from the front end surface of the fixed platform 1.

[0034] In a further embodiment, the fixed pulley 6 is connected to the top ends of the first diagonal support rod 15 and the second diagonal support rod 16 in a rotational connection.

[0035] During use, when the first motor 2 rotates, it drives the driving wheel 3 to rotate, and under the action of the transmission belt 4, the driven wheel 5 and the first rotating rod 12 rotate synchronously. At this time, the winding drum 13 symmetrically installed on the outside of the first rotating rod 12 winds the lifting line 7, so that the glass curtain wall lifting frame 8 moves under the action of the two lifting lines 7.

[0036] according to Figure 3-6 As shown, a moving platform mechanism is installed inside the glass curtain wall hoisting frame 8, a suction cup grabbing mechanism is provided above the moving platform mechanism, and a protective frame 9 is installed on one side of the suction cup grabbing mechanism.

[0037] Specifically, the moving platform mechanism includes a screw mechanism 17 installed inside the glass curtain wall hanging frame 8, and a moving block 18 is symmetrically provided outside the screw mechanism 17, and the top of the moving block 18 is connected to the bottom of the moving platform 19.

[0039] When the glass curtain wall inside the protective frame 9 deviates from the position of the required installation location, the motor in the screw mechanism 17 is turned on, and the movable platform 19 moves left and right under the action of the screw mechanism 17, thereby changing the position of the glass curtain wall to match the installation location.

[0040] Specifically, the suction cup grasping mechanism includes a height synchronization adjustment device and a suction cup fixing device.

[0041] In a further embodiment, the height synchronization adjustment device includes an installation box 20, and the bottom of the installation box 20 is connected to the top of the moving platform 19, a second rotating rod 21 is installed inside the installation box 20, and one end of the second rotating rod 21 is connected to the output end of the second motor 22 outside the installation box 20, a first bevel gear 23 is symmetrically arranged on the outside of the rotating rod 21, and the first bevel gear 23 is meshed with the second bevel gear 24, the inside of the second bevel gear 24 is connected to the threaded rod 25, and one end of the threaded rod 25 passes through the top of the installation box 20 and is threadedly connected to the inside of the moving column 26, a suction cup fixing device is installed on the top of the moving column 26, and a limit sleeve 27 is provided on the outside of the moving column 26, and the limit sleeve 27 is installed above the installation box 20.

[0042] In a further embodiment, the suction cup fixing device includes an electric telescopic rod 28, and the electric telescopic rod 28 is connected to the top of the movable column 26. A fixed plate 29 is installed at the output end of the electric telescopic rod 28, and several groups of suction cups 30 are arranged on the outside of the fixed plate 29. The suction cups 30 are connected to the vacuum pump 31 inside the fixed plate 29 through a vacuum suction tube.

[0043] In a further embodiment, two sets of suction cup fixing devices are provided to make the glass curtain wall more firmly adsorbed, thereby reducing the risk of the glass curtain wall falling when being grasped.

[0044] When the glass curtain wall needs to be placed inside the protective frame 9, the electric telescopic rod 28 is turned on, so that the output end of the electric telescopic rod 28 drives the fixed plate 29 to move until the suction cup 30 outside the fixed plate 29 is in close contact with the glass curtain wall. At this time, the vacuum pump 31 is turned on, and the vacuum pump 31 extracts the air inside the suction cup 30 through the vacuum pipe, so that the connection between the suction cup 30 and the glass curtain wall is in a vacuum state to make the connection tighter. After the connection is completed, the second motor 22 is turned on to drive the second rotating rod 21 and the first bevel gear 23 to rotate. Under the action of the second bevel gear 24 and the threaded rod 25, the moving column 26 moves up and down inside the limit sleeve 27, so that the suction cup fixing device drives the glass curtain wall to move up and down, so that the bottom of the glass curtain wall is at the same height as the inner bottom of the protective frame 9. At this time, the electric telescopic rod 28 is controlled so that its output end drives the suction cup 30 and the glass curtain wall to move until the glass curtain wall is placed inside the protective frame 9.

The inner side of the protective frame 9 is connected to the buffer plate 32 through a spring, and the inner side of the buffer plate 32 is covered with a side of buffer cotton.

[0046] During use, when the glass curtain wall is placed inside the protective frame 9 under the action of the suction cup grasping mechanism, the protective frame 9 can protect the outer frame of the glass curtain wall to a certain extent. At the same time, when the glass curtain wall vibrates, the buffer cotton can prevent the buffer plate 32 from causing damage to the glass curtain wall, and the spring plays a certain buffering and shock-absorbing role, reducing the chance of the glass curtain wall being bumped and damaged in the protective frame 9.
