[0015] Furthermore, a method for hoisting an assembled hollow sandwich panel hoisting device comprises the following steps:

[0016] Step 1: Assemble the clamping frame according to the clamping length of the hollow sandwich plate, connect the front and rear ends of the two clamping frames, and use the connecting steel plate to fix and limit the connection between the two adjacent clamping frames.

[0017] Step 2: After the side of the hollow sandwich panel is clamped by the clamping part, the adjusting rod is controlled to rotate inside the movable groove by controlling the output shaft of the motor, and the adjusting rod is used to rotate inside the two adjusting blocks. Since the two adjusting blocks are provided with internal threaded holes with opposite rotation directions, when the adjusting rod rotates clockwise, the two adjusting blocks move forward and backward along the inside of the movable groove, and the front and rear side positions of the two adjusting blocks at the top of the clamping part are adjusted, so as to adjust the hoisting center of gravity of the hollow sandwich panel;

[0018] Step three, when hoisting and clamping the hollow sandwich panel, a plurality of hydraulic clamps inside the clamping frame are used to clamp and fix a plurality of shear keys inside the hollow sandwich panel, and the upper electric rotating frame located above one side of the hydraulic clamp and the lower electric rotating frame below the clamping frame are used to clamp and position the upper and lower sides of the hollow sandwich panel respectively, and at the same time, the micro-electric cylinder driving ends in the two movable clamps on the hydraulic clamp are used to control the upper and lower support frames to contact the upper and lower sides of the inner wall of the hollow sandwich panel respectively, and at the same time, the electric rotating shaft is used to drive the limit plate to flip inside the hollow sandwich panel, and one side of the shear key inside the hollow sandwich panel is limited by the two limit plates;

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] 1. The hoisting equipment in the present invention successfully realizes the stable hoisting, flexible adjustment and safe positioning of the assembled hollow sandwich panels through the design of the structure composed of the control frame, the rotating frame, the sling, the adjustment component, the clamping component and the hydraulic clamp, and significantly improves the construction efficiency and safety. The control of the lifting center of gravity of the hollow sandwich panels can be achieved through the adjustment component and the hoisting center of gravity adjustment design, and the sandwich panels can be smoothly passed and guided even in narrow space areas to ensure that they are level with the ground after adjustment, which greatly improves the stability during the hoisting process; the hollow sandwich panels can be effectively clamped and positioned on both sides through the clamping component, and can be flexibly adjusted and quickly assembled according to the change of the clamping length, ensuring the protection of the internal and external structures of the hollow sandwich panels during the clamping and fixing process, especially in the hoisting of hollow sandwich panels of different specifications and sizes. The modular design greatly improves the flexibility of the equipment.

[0022] 2. The invention solves the problem of accurate positioning and fixing of internal detail structures such as shear keys by introducing hydraulic clamps. Through the combination of mechanics and electrical, the clamping and fixing of components inside the hollow sandwich plate is completed efficiently and stably, effectively avoiding damage to the surface quality of the components and ensuring the safety and quality of the construction.

[0023] 3. In the present invention, the clamping components arranged on the left and right sides are used to clamp and position the two sides of the hollow sandwich panel, and the adjusting components inside the control frame are used to adjust and control the lifting center of gravity of the hollow sandwich panel to ensure the stability of the hollow sandwich panel during the lifting process. In addition, when lifting the hollow sandwich panel in a narrow space, the left and right sides of the hollow sandwich panel are tilted by the adjusting components, thereby ensuring that the hollow sandwich panel can be smoothly lifted from the narrow space. After passing through the narrow space, the lifting center of gravity of the hollow sandwich panel is adjusted by the adjusting components to make the hollow sandwich panel and the ground in a horizontal state, thereby greatly improving the lifting stability of the hollow sandwich panel. When installing the hollow sandwich panel, the control frame is controlled to rotate horizontally by the rotating frame, thereby improving the installation flexibility of the hollow sandwich panel.

[0024] 4. After the clamping part is used to clamp the side of the hollow sandwich panel, the present invention controls the adjusting rod to rotate inside the movable groove by controlling the output shaft of the motor, and uses the adjusting rod to rotate inside the two adjusting blocks. Since the two adjusting blocks are provided with internal threaded holes with opposite rotation directions, when the adjusting rod rotates clockwise, the two adjusting blocks are displaced forward and backward along the inside of the movable groove. By adjusting the front and rear side positions of the two adjusting blocks at the top of the clamping part, the lifting center of gravity of the hollow sandwich panel is adjusted to ensure the stability of the center of gravity of the hollow sandwich panel during the lifting process, thereby greatly improving the lifting stability of the hollow sandwich panel. In addition, by adopting a plurality of clamping frames to assemble the clamping part, the clamping structure of the hollow sandwich panel is easy to transport, and at the same time, suitable clamping parts can be quickly assembled according to hollow sandwich panels of different specifications and sizes, thereby improving the use flexibility of the hollow sandwich panel lifting structure.
