[0039] The lifting mechanism 3 is arranged on the front side of the connecting table 2. Specifically, the lifting mechanism 3 comprises a moving block 31, a moving groove 32 is vertically formed on the front side of the connecting table 2, the moving block 31 is slidingly assembled in the moving groove 32, the inner walls on both sides of the moving groove 32 are rotatably assembled with a second lead screw 33, the moving block 31 is threadedly connected with the second lead screw 33, an assembling mechanism 4 is installed on the front side of the moving block 31, and a first motor 34 is fixedly installed on the top of the connecting table 2. The output shaft of the first motor 34 is in transmission connection with the second lead screw 33.

[0040] In use, the staff can control the output shaft of the first motor 34 to rotate forward or reverse through the controller 15. After the four first suction cups 53 and the four second suction cups 56 are adsorbed to the glass, when it is necessary to install at a certain height, the staff can directly drive the second lead screw 33 to rotate through the first motor 34, the second lead screw 33 drives the moving block 31 to move up and down, and then the position of the glass is adjusted up and down until the installation position is aligned for installation. In this way, the staff does not need to lift the glass curtain wall, the labor intensity of the staff is reduced, and the applicability is strong.

[0041] The assembling mechanism 4 is arranged on the front side of the lifting mechanism 3. Specifically, the assembling mechanism 4 comprises an installation table 501, the installation table 501 is fixedly installed on the front side of the moving block 31, three assembling grooves 502 are symmetrically formed on the front side of the installation table 501, two matching blocks 503 are slidingly assembled in each of the three assembling grooves 502, two installation mechanisms 5 are respectively fixedly connected with the front ends of the upper and lower three matching blocks 503, a bidirectional threaded rod 504 is rotatably assembled in the central assembling groove 502, the two matching blocks 503 in the central assembling groove 502 are threadedly connected with the right-handed threaded segment and the left-handed threaded segment of the bidirectional threaded rod 504, and a second motor 505 is fixedly installed on the top of the installation table 501. The output shaft of the second motor 505 is in transmission connection with the bidirectional threaded rod 504.

[0042] In the initial state, according to the size of the glass curtain wall to be installed, the distance between the two installation mechanisms 5 is adjusted, so that the distance between the upper two first suction cups 53 and the second suction cup 56 can be increased or decreased compared with the distance between the lower two first suction cups 53 and the second suction cup 56, which is suitable for adsorbing glass curtain walls of different sizes. The four first suction cups 53 and the four second suction cups 56 can be adjusted in position to adsorb the glass curtain wall in a reasonable position, so that the center of gravity of the glass curtain wall is stable during installation, and the adsorption effect is better. When adjusting, the controller 15 controls the output shaft of the second motor 505 to drive the bidirectional threaded rod 504 to rotate. Since the two matching blocks 503 at the center are threadedly connected with the forward threaded section and the reverse threaded section of the bidirectional threaded rod 504, the forward and reverse rotation of the bidirectional threaded rod 504 can drive the two matching blocks 503 at the center to move closer to each other and farther away from each other, thereby achieving the purpose of adjusting the distance. It is simple and convenient to operate.

[0043] The installation mechanism 5 is provided with two installation mechanisms 5, which are arranged in an up-down distribution on the front side of the assembly mechanism 4. The installation mechanism 5 is arranged in a left-right distribution on the side away from the assembly mechanism 4. The specific installation mechanism 5 includes an installation block 521, and the rear side of the installation block 521 is fixedly connected with the front ends of the three matching blocks 503.

The two installation blocks 521 are fixedly installed with a protection box 525 on the side away from each other. The two protection boxes 525 are fixedly installed with a third motor 526 on the side away from each other. The output shafts of the two third motors 526 are respectively in transmission connection with the two transmission sprockets 524.

[0048] Since the engagement between the worm gears 523 and the worm gears 527 has self-locking properties, the four connecting blocks 42 cannot rotate in the initial state, and before the glass curtain wall is adsorbed, the positions of the four second suction cups 56 are adjusted according to the current of the glass curtain wall, so that they can be evenly distributed to match the area of the curtain wall and achieve the effect of gravity balance. When adjusting, the staff controls the controller 15 to control the start of the two third motors 526, and the two third motors 526 can drive one of the transmission sprockets 524 on the upper and lower sides to rotate, and the four transmission sprockets 524 are driven to rotate through the two transmission chains, as shown in Figure 5 As shown in Figure 6 , the two worm gears 523 rotate in the same direction, and the left two worm gears 523 and the right two worm gears 523 are mirror images with the central mounting groove 502 as the center, so the left two worm gears 523 and the right two worm gears 523 rotate in opposite directions, so they can drive one end of the four connecting blocks 42 to adjust the angle to achieve the purpose of changing the distribution position. When not in use, the two third motors 526 are turned off.

[0049] The connecting block 52 is fixedly installed at the front end of the shaft 51, the first suction cup 53 matched with the position of the shaft 51 is fixedly installed on the front side of the connecting block 52, the sliding groove 54 is formed on the front side of the connecting block 52, the sliding block 55 is slidably assembled in the sliding groove 54, the second suction cup 56 is fixedly installed on the front side of the sliding block 55, the first lead screw 57 is rotatably assembled on the inner wall of the sliding groove 54 close to the shaft 51, the end of the first lead screw 57 extends out of the connecting block 52 and is fixedly installed with the turntable 58 on the end face, the holding rod 59 is eccentrically arranged on the side of the turntable 58 away from the lead screw 57, and the sliding block 55 is threadedly connected with the first lead screw 57.

[0050] The vacuum pump 6 is fixedly installed on the left side of the connecting table 2, and the suction end of the vacuum pump 6 is provided with a connecting pipe 61. The plurality of first suction cups 53 and the plurality of second suction cups 56 are fixedly communicated with the connecting pipe 61 through hoses.

[0051] The use method of the device is as follows:

[0052] In use, the bottom plate 12 is moved to the specified position by the four moving wheels 14, and before the glass curtain wall is installed, the rotation angle of the four connecting blocks 52, the distance between the two mounting tables 501, and the distance between the four second suction cups 56 compared to the four first suction cups 53 are adjusted according to the size of the glass curtain wall. When adjusting the rotation angle of the four connecting blocks 52, the two third motors 526 are started, the two third motors 526 drive the two transmission sprockets 524 to rotate, and then the four worm gears 527 are driven to rotate through the two transmission chains, and the four worm gears 523 are driven to rotate, achieving the purpose of adjustment.

[0053] When adjusting the distance between the four second suction cups 56 and the four first suction cups 53, the rotating disc 58 at the specified position is rotated, the rotating disc 58 drives the first screw rod 57 to rotate, the sliding block 55 is driven to move left and right through the threaded connection between the sliding block 55 and the first screw rod 57, and then the position of the second suction cup 56 is adjusted;

[0054] When adjusting the distance between the two mounting tables 501, the output shaft of the second motor 505 is controlled to rotate forward or reversely, and then the bidirectional screw rod 504 is driven to rotate forward or reversely, so that the two mounting tables 501 are driven to move close to each other or away from each other. The above adjustment mode can enable the four first suction cups 53 and the four second suction cups 56 to adsorb glass curtain walls of different sizes, and the four first suction cups 53 and the four second suction cups 56 are reasonably distributed, the center of gravity of the adsorbed glass curtain wall is stable, the reliability is high, and the glass curtain wall is placed on the assembling frame in the prior art or manually operated to stand in front of the four first suction cups 53 and the four second suction cups 56 during adsorption. Then, the four first suction cups 53 and the four second suction cups 56 are pressed to contact the glass curtain wall, the vacuum pump 6 is started to extract the air in the four first suction cups 53 and the four second suction cups 56, so that the four first suction cups 53 and the four second suction cups 56 are in a vacuum state, and the adsorption purpose is achieved. During subsequent installation, the glass curtain wall can be lifted to a specified height by the lifting mechanism 3, and the bottom plate 12 is moved to make the glass curtain wall fit the installation site, so that the staff does not need to manually lift, and the labor intensity of the staff is reduced.
