[0003] The current hoisting of exterior wall panels has the following shortcomings: 1. Traditional hoisting methods mostly use magnetic adsorption or suction cup adsorption to hoist the panels, but exterior wall panels are mostly made of non-metallic materials and often have gaps on the outer surface. Since they are high-altitude operations, their magnetic adsorption and suction cup adsorption cannot guarantee the stability of high-altitude operations; 2. Currently, exterior wall panels are mostly hoisted vertically by clamping the top. During the hoisting process of exterior wall panels, due to the downward center of gravity, they are prone to violent shaking at high altitudes, causing the exterior wall panels to be loosely clamped and fixed and fall.

[0022] In step 1, the hook of the crane is hung on the eyebolt, and the crane is driven to rise above the exterior wall panel and slowly lowered so that the bottom surface of the cross-shaped channel steel just falls on the top surface of the exterior wall panel. The motor shaft of the servo motor is controlled to rotate in the forward direction, and the motor shaft of the servo motor drives the driving gear to rotate synchronously. The driving gear is engaged in sequence to drive the four linkage gears, four linkage shafts and four first sprockets to rotate synchronously in the opposite direction.

[0023] Step 2: The four first sprockets are engaged in sequence through the drive chain belts to drive the four second sprockets, the four fixed shafts and the four pairs of fixed gears to rotate synchronously in the forward direction. Each pair of the fixed gears is engaged to drive the corresponding first rack and the second rack to translate toward the middle, thereby synchronously driving the first U-shaped slide bar to slide inward along the first slide hole and the second U-shaped slide bar to slide inward along the second slide hole.

[0024] Step 3: When the two pairs of second plywood are first pressed against the front and rear side walls of the exterior wall panel, the T-shaped slide bar is then driven to slide outward along the positioning slide hole, causing the tension spring to deform. Then, the two pairs of first plywood are pressed against the left and right side walls of the exterior wall panel, and the driving operation of the servo motor is stopped. At this time, the two pairs of first plywood and the two pairs of second plywood are respectively pressed against the outer side walls of the exterior wall panel;

[0025] Step 4: Synchronously control the extension of the telescopic rods of the first telescopic cylinder and the second telescopic cylinder. The telescopic rod of the first telescopic cylinder slowly extends, and under the hinged action of the first U-shaped seat, the first folding plate is slowly driven to swing in a hinged manner through the first connecting rod, so that the inner side of the first folding plate is tightly pressed against the left and right edges of the bottom surface of the exterior wall panel.

[0026] Step 5: The telescopic rod of the second telescopic cylinder is slowly extended. Under the hinged action of the second U-shaped seat, the second folding plate is slowly driven to swing through the second connecting rod, so that the inner side of the second folding plate is pressed against the front and rear edges of the bottom of the exterior wall plate. At this time, the first folding plate and the second folding plate are respectively pressed against the bottom edges of the exterior wall plate;

[0027] Step six: by cooperating with the crane and the sling, the exterior wall panels are moved to a suitable position and slowly lowered. Then, the telescopic rods of the first and second telescopic cylinders are controlled to shorten, and then the motor shaft of the servo motor is controlled to rotate in the opposite direction, thereby releasing the clamping effect on the exterior wall panels in turn.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the present invention, by using a linkage mechanism, two pairs of first clamping plates and two pairs of second clamping plates are respectively pressed against the outer side walls of the exterior wall panels, which can effectively clamp and fix exterior wall panels of different sizes, achieve more precise control of the lifting operation, and improve the working efficiency of the lifting device;

[0030] 2. In the present invention, the first telescopic cylinder drives the inner side of the first folding plate to press against the left and right edges of the bottom surface of the exterior wall panel, while the second telescopic cylinder drives the inner side of the second folding plate to press against the front and rear edges of the bottom surface of the exterior wall panel. This ensures that the bottom of the exterior wall panel is in a tight position during hoisting, improving the safety of the hoisting process and the practicality of the hoist.

[0031] In summary, the present invention solves the problems of weak clamping and poor stability of exterior wall panels, and the overall structural design is compact. By clamping and fixing the exterior wall panels in multiple directions, the stability of the exterior wall panel hoisting is ensured, which not only reduces the construction difficulty but also improves the construction safety.

5. A method for hoisting an exterior wall panel hoist according to claim 4, characterized in that: The following steps are involved: In step 1, the hook of the crane is hung on the eyebolt, and the crane is driven to rise above the exterior wall panel and slowly lowered so that the bottom surface of the cross-shaped channel steel just falls on the top surface of the exterior wall panel. The motor shaft of the servo motor is controlled to rotate in the forward direction, and the motor shaft of the servo motor drives the driving gear to rotate synchronously. The driving gear is engaged in sequence to drive the four linkage gears, four linkage shafts and four first sprockets to rotate synchronously in the opposite direction. Step 2: The four first sprockets are engaged in sequence through the drive chain belts to drive the four second sprockets, the four fixed shafts and the four pairs of fixed gears to rotate synchronously in the forward direction. Each pair of the fixed gears is engaged to drive the corresponding first rack and the second rack to translate toward the middle, thereby synchronously driving the first U-shaped slide bar to slide inward along the first slide hole and the second U-shaped slide bar to slide inward along the second slide hole. Step 3: When the two pairs of second plywood are first pressed against the front and rear side walls of the exterior wall panel, the T-shaped slide bar is then driven to slide outward along the positioning slide hole, causing the tension spring to deform. Then, the two pairs of first plywood are pressed against the left and right side walls of the exterior wall panel, and the driving operation of the servo motor is stopped. At this time, the two pairs of first plywood and the two pairs of second plywood are respectively pressed against the outer side walls of the exterior wall panel; Step 4: Synchronously control the extension of the telescopic rods of the first telescopic cylinder and the second telescopic cylinder. The telescopic rod of the first telescopic cylinder slowly extends, and under the hinged action of the first U-shaped seat, the first folding plate is slowly driven to swing in a hinged manner through the first connecting rod, so that the inner side of the first folding plate is tightly pressed against the left and right edges of the bottom surface of the exterior wall panel. Step 5: The telescopic rod of the second telescopic cylinder is slowly extended. Under the hinged action of the second U-shaped seat, the second folding plate is slowly driven to swing through the second connecting rod, so that the inner side of the second folding plate is pressed against the front and rear edges of the bottom of the exterior wall plate. At this time, the first folding plate and the second folding plate are respectively pressed against the bottom edges of the exterior wall plate; Step six: by cooperating with the crane and the sling, the exterior wall panels are moved to a suitable position and slowly lowered. Then, the telescopic rods of the first and second telescopic cylinders are controlled to shorten, and then the motor shaft of the servo motor is controlled to rotate in the opposite direction, thereby releasing the clamping effect on the exterior wall panels in turn.
