The secondary frame 10, the main frame 9, and the secondary frame 10 are connected to the top of the storage plate 3 by fixing components. Rope fixing components are set at the four corners of the storage plate 3, and ropes 25 are wound around the four rope fixing components. The upper end of the rope 25 is suspended from the bottom end of the hook 7. By the winding and unwinding operation of the winch 5, the rope 25 is driven to drive the storage plate 3 and the material on it to rise and fall vertically. This design structure is stable. The support frame 2 and the top seat 4 provide reliable support for the winch 5. The base 1 ensures the stability of the overall equipment. The combined structure of the main and secondary frames can adjust the bearing area of ​​the storage plate 3 as needed. The rope fixing design facilitates the fixing and adjustment of the material lifting rope.

[0030] Reference Figure 3-6 The tenon 15 fixed at one end of the main frame 9 is inserted into the mortise 16 opened at one end of the secondary frame 10 to achieve splicing. A groove 1 is opened on one side of the main frame 9, and a groove 2 is opened on the corresponding side of the secondary frame 10. The stabilizing buckle 11 is inserted into the groove 1 and groove 2 and locked by the pin 12 of the limiting holes at both ends. This connection method allows the main frame 9 and the secondary frame 10 to be quickly assembled and disassembled. The front end of the main frame 9 is designed with an insertable pin 2 13, and is fixed with a protrusion 2 17 and an interface 18. Its rear end is fixed with a protrusion 14 and an interface 2 19. The design of these protrusions and interfaces allows multiple main frames 9 to be connected and locked by interlocking the protrusions and interfaces and by using the pin 2 13, so as to realize the extension of the frame to adapt to materials of different sizes and meet the transportation needs of different materials.

[0031] Reference Figure 7 The connection between the shelf 3 and the main frame 9 and the sub-frame 10 below is achieved by the shelf fixing bracket 20 sleeved on the outer wall of the sub-frame 10. The top of the shelf fixing bracket 20 passes through the reserved holes at the four corners of the shelf 3 and is fastened by the bolts 21 inserted into the fixing holes at the top. This design allows the shelf 3 to be firmly installed on the frame, and the fastening method of the bolts 21 facilitates the installation, disassembly or replacement of the shelf 3.

[0032] Reference Figure 8 and Figure 9The rope-fixing housing 8, which is fixedly connected to the four corners of the shelf 3, has a component groove inside. A threaded post 22 is fixedly connected to the middle of the component groove. A limit groove is opened at the end of the threaded post 22 away from the rope-fixing housing 8. A nut 23 is sleeved on the outer wall of the limit groove. A slot 24 is opened at the bottom end of the rope-fixing housing 8 near the nut 23. In use, the rope 25 is wound around the threaded post 22, one end passes through the slot 24, and the rope 25 is fixed by tightening the nut 23. The other end extends out from the threaded post 22 and is wound around the end of the rope 25 fixed by the nut 23. This design is simple and reliable, ensuring that the rope 25 is wound securely.

[0033] Working principle: Based on the size and shape of the material to be supported, the main frame 9 and the secondary frame 10 are assembled using a mortise and tenon structure. Specifically, the tenon 15 at one end of the main frame 9 is inserted into the mortise 16 at one end of the secondary frame 10. A stabilizing buckle 11 is inserted into the corresponding groove 1 on one side of the main frame 9 and the corresponding groove 2 on the secondary frame 10. The two ends of the stabilizing buckle 11 are locked with a pin 12 to ensure a secure connection. If a larger support platform is required, multiple main frames 9 can be interlocked with each other via the front protrusion 17 and interface 18 and the rear protrusion 14 and interface 19, secured with pin 2. 13. Lock the frame in place to extend its reach. Place the shelf 3 on top of the main frame 9 and the secondary frame 10. Fit the shelf fixing bracket 20 onto the outer wall of the secondary frame 10, with its top end passing through the pre-drilled holes at the four corners of the shelf 3. Insert the bolt 21 into the fixing hole at the top of the shelf fixing bracket 20 and tighten it to securely fix the shelf 3 to the frame. Wrap the four ropes 25 around the threaded posts 22 in the rope fixing assembly at the four corners of the shelf 3. One end of the rope 25 passes through the slot 24 at the bottom of the rope fixing housing 8, wraps around the threaded post 22, and then wraps the other end around the already fixed... Tighten nut 23 on the rope segment to securely fix the wound rope 25 to the threaded post 22 using its clamping force. Gather the upper ends of the four ropes 25 and suspend them on the hook 7 at the bottom of the winch 5. Place the construction materials to be transported vertically on the installed platform 3. Start the winch 5 installed on the top seat 4. The winch 5 performs a winding operation, winding the internal steel cable, thereby lifting the hook 7 upward. The hook 7 pulls the four ropes 25 upward. The ropes 25 pass through the fixed point at their lower ends on the rope fixing housing 8, pulling the platform 3 and the materials on it upward. Support frame 2 and The top seat 4 provides a solid support foundation for the winch 5, the stabilizer 6 enhances the connection rigidity between the left and right support frames 2 to prevent swaying, and the base 1 ensures the stability of the entire equipment on the ground. When the material needs to be lowered, the winch 5 is operated to unwind, the winch 5 releases its internal steel cable, and the hook 7 slowly descends under the action of gravity. The hook 7 relaxes the tension on the rope 25, and under the action of the weight of the material and the placement plate 3 itself, the placement plate 3 descends vertically. When the placement plate 3 descends to a suitable height, the winch 5 is stopped, and the material on the placement plate 3 is safely unloaded.
