The frame 1 is a main frame structure for carrying and moving glass, and is provided with a plurality of universal wheels 14 at the bottom to provide the function of walking of the device during glass carrying and position adjustment during glass installation. The lifting mechanism 5 can drive the glass to actively lift. Specifically, the lifting mechanism 5 is installed with the lifting frame 2, the cross section of the lifting frame 2 is in U-shaped structure, and the lower side of the middle is provided with the rotating hole 21. The suction cup frame 3 is installed in the rotating hole 21, the suction cup frame 3 is located in the U-shaped structure of the lifting frame 2 as a whole, and there is a gap between the two sides of the suction cup frame 3 and the lifting frame 2. A plurality of vacuum suction cups 32 are symmetrically arranged on the suction cup frame 3, and the auxiliary bottom plate 33 assists in supporting the glass to make the glass installation more stable and safe.Figure 6 As shown, in order to make the glass smoothly into the window frame, the auxiliary bottom plate 33 only holds a part of the bottom of the glass.

[0027] Referring to Figure 5 , the lifting mechanism 5 includes a lead screw 51 rotatably connected at both ends to the center surface of the frame 1, the top of the lead screw 51 is fixedly connected to a large bevel gear 53, the large bevel gear 53 is meshed with a small bevel gear 54, and the small bevel gear 54 is provided with a second handle 56; the lead screw 51 is provided with a lead screw nut 52, the lead screw nut 52 is arranged in the middle of the lifting rod 4, and the two ends of the lifting rod 4 are respectively connected to the two ends of the lifting chain 6, the lifting chain 6 is connected to the lifting frame 2, and the small bevel gear 54 is driven through the second handle 56; the lead screw 51 drives the lifting rod 4 to move up and down through the lead screw nut 52 provided thereon, the lifting of the lifting rod 4 drives the lifting chain 6 to move, and the lifting chain 6 drives the lifting frame 2 and the suction cup frame 3 to move up and down synchronously. The small bevel gear 54 and the second handle 56 are connected through a rotating shaft, the rotating shaft is arranged in a bearing seat 55, and the bearing seat 55 is fixedly connected to the frame 1 through bolts. The lead screw nut 52 is fixedly connected to the lifting rod 4, and the lead screw 51 cooperates with the lead screw nut 52. The second handle 56 drives the small bevel gear 54, the large bevel gear 53, and the lead screw 51 to rotate in sequence, and the lead screw 51 drives the lifting rod 4 to move up and down through the lead screw nut 52. When the lifting rod 4 rises, the lifting frame 2 and the suction cup frame 3 are driven to rise synchronously through the lifting chain 6; when the lifting rod 4 descends, the lifting frame 2 and the suction cup frame 3 descend synchronously under the action of gravity. The lifting mechanism 5 can also not use a lead screw and a bevel gear, but use other transmission modes, such as a manual pump + hydraulic cylinder manual mode. If it is further desired to reduce the intensity of human operation, the lifting mechanism 5 can also use a driving mode composed of a motor, an electric cylinder, an air cylinder, a hydraulic cylinder, etc.

[0028] Further, the suction cup frame 3 is connected to a drive sprocket 31 through a suction cup frame rotating shaft at both sides, the suction cup frame 3 is adjusted in angle through the drive sprocket 31, the drive sprocket 31 is connected to the manual sprocket 25 through the adjusting chain 7 to rotate, and the manual sprocket 25 is driven through the first handle 26. This embodiment is used for the installation of vertical glass in most cases, and sometimes the angle of the glass needs to be adjusted to deflect to make it smoothly into the window frame, so the suction cup frame 3 is designed to be reversibly rotated in the lifting frame 2 to realize small amplitude deflection left and right, so as to meet the needs of rotation adjustment in the vertical plane in the glass installation process. Specifically, referring to Figure 2 , Figure 4, the suction cup frame 3 is symmetrically provided with a suction cup frame rotating shaft (not shown in the figure) on one side close to the lifting frame 2, the suction cup frame rotating shaft can be rotated left and right by a small amplitude through a driving sprocket 31 connected by rotation, the driving force of the driving sprocket 31 is transmitted in turn through the first handle 26, the manual sprocket 25 and the adjusting chain 7, the driving manual sprocket 25 and the driving sprocket 31 are rotated by operating the first handle 26, and the driving sprocket 31 is engaged with the lifting chain 6, which can ensure the stability of the driving sprocket 31 during rotation. Among them, the index circle of the manual sprocket 25 is set to be much smaller than the index circle of the driving sprocket 31, the purpose is to realize the adjustment angle is fine tuning and labor saving. During the lifting process of the lifting frame 2, the driving sprocket 31 is equivalent to the driving pulley principle, so it is a labor-saving mechanism. For example, the total weight of glass + lifting frame 2 + suction cup frame 3 + lifting rod 4 is 1 ton, the actual lifting force of the lifting mechanism 5 only needs 0.5 ton, that is, the lifting operation can be realized. If you want to further reduce the intensity of manual operation, the deflection adjustment of the suction cup frame 3 can also use the driving mode composed of motors, hydraulic motors and other structures.

[0029] Referring to Figure 2 , as preferred, the driving sprocket 31 is a double-row sprocket structure, which includes a front sprocket 311 and a rear sprocket 312 fixedly connected and synchronously rotated, the front sprocket 311 is engaged with the lifting chain 6, and the rear sprocket 312 is engaged with the adjusting chain 7. The driving sprocket 31 can adopt a double-row sprocket structure or a single-row sprocket combined with an independent angle adjusting sprocket. In order to facilitate installation and adjustment, a double-row sprocket structure is adopted in the embodiment. Specifically, the driving sprocket 31 is divided into a front sprocket 311 and a rear sprocket 312, the front sprocket 311 and the rear sprocket 312 are fixedly connected and synchronously rotated, the front sprocket 311 can rotate with the lifting chain 6, and the rear sprocket 312 rotates with the adjusting chain 7. After the glass height is lifted to the position, the two driving sprockets 31 (the two driving sprockets 31 are rotatably connected with the suction cup frame 3, and the distance between the two driving sprockets 31 is always unchanged) are driven to rotate by the manual sprocket 25 through the chain 7. That is, the driving sprocket 31 and the lifting chain 6 will move relatively at this time, but the lifting chain 6 is stationary at this time, so the driving sprocket 31 will drive the suction cup frame 3 to rotate around the center rotating hole 21.

[0030] Further, the top and bottom of the rack 1 are symmetrically provided with a fixed sprocket 11, the lifting chain 6 is arranged on the fixed sprocket 11, and the index circle of the fixed sprocket 11 is equal to the index circle of the front sprocket 311, and the index circle of the rear sprocket 312 is much larger than the index circle of the manual sprocket 25, so that the lifting chain 6 can always keep “zero relative sliding, zero pitch difference” with the driving sprocket 31 during lifting, which can not only synchronize the lifting motion to the suction cup frame 3, but also not damage the angle adjusting accuracy.

[0031] Further, the manual sprocket 25 is connected with the first handle 26 through the sprocket shaft 24, the sprocket shaft 24 is installed on the lifting frame 2 through the sliding block 23, the sliding block 23 is symmetrically provided with the sliding groove 231 on both sides, the lifting frame 2 is provided with the notch 22 at the installation position of the sliding block 23, and the notch 22 is provided with the sliding rail 221 matched with the sliding groove 231 on both sides.

Referring to Figure 2 、 Figure 4 , in order to adjust the tension of the adjusting chain 7, the T-shaped head screw 27 is arranged on the top of the sliding block 23. The T-shaped head screw 27 and the pressing plate 28 are fastened by the locking nut 29. The adjusting chain 7 sequentially passes through the manual sprocket 25 and the rear sprocket 312 to form a closed loop. The T-shaped head screw 27 is adjusted to adjust the sliding block 23 to slide up and down, so that the adjusting chain 7 is properly tensioned.

[0033] Further, the front guide mechanism 12 is arranged between the rack 1 and the lifting frame 2, and the rear guide mechanism 13 is arranged between the rack 1 and the lifting rod 4. Referring to Figure 1 、 Figure 7 , in order to provide the lifting function of the lifting frame 2 and the lifting rod 4, the front guide mechanism 12 is arranged on the glass dismounting side of the rack 1, and the rear guide mechanism 13 is arranged on the personnel operation side, so that the stability and smoothness of the lifting process of the lifting frame 2 and the lifting rod 4 are increased.

[0034] As a preferred, the front guide mechanism 12 and the rear guide mechanism 13 can be linear guides, rollers or guide rods.

[0035] Further, the rack 1 is further provided with the counterweight 15 away from the lifting frame 2. In order to prevent accidents caused by tipping of the trolley during operation, the counterweight 15 is installed on the side of the rack 1 away from the lifting frame 2, and the counterweight 15 can be made of lead or concrete and other materials that can be used as counterweights.

[0036] When installing glass, the operator walks into the frame 1 to the glass storage position, adjusts the vacuum chuck 32 to the appropriate height by operating the second handle 56, so that the auxiliary bottom plate 33 can support the glass, drives the vacuum chuck 32 to suck the glass by operating the pneumatic equipment, walks to the glass installation position, and adjusts the glass to the required installation position by operating the second handle 56 and the first handle 26 for installation. When disassembling the glass, the operation process is opposite to that of installing the glass. During the installation and disassembly of the glass, the operator is always located inside the frame 1, and the frame 1 forms a protection in front of and on both sides of the operator, which can prevent the glass from sliding and tilting accidentally to injure the operator, thereby effectively ensuring the safety of the operation.
