Description

Technical Field

[0001] This utility model relates to the field of stone technology, and in particular to a stone lifting tool for stone processing. Background Technology

[0002] Stone is a high-end building decoration material widely used in interior and exterior decoration design, curtain wall decoration and public facility construction. Artificial stone is divided into terrazzo and synthetic stone according to the process. Terrazzo is made by pressing cement and concrete and other raw materials, while synthetic stone is made by pressing and polishing crushed natural stone and adding adhesives.

[0003] The existing utility model with authorization announcement number CN221140894U discloses a stone lifting tool for stone processing, including two sets of bases, a main rod installed on the top of each set of bases, a support rod installed inside the main rod, a crossbeam installed at the top of the inner side of the support rod, and a clamping mechanism installed below the crossbeam.

[0004] Although the above-mentioned technical solution achieves stone clamping by activating the telescopic rod, which drives the fixed rod to move back and forth, and by fixing the fixed block to the fixed rod, allowing the fixed block to slide in the groove, causing the connecting blocks to move closer and further away from each other outside the sliding rod, thus moving the clamping plates closer together, and effectively increasing friction with the silicone pad to make the clamping more stable, the above-mentioned technical solution only facilitates stone clamping. During the movement of the lifting device, it is easily affected by road surface factors, causing the lifting device to sway and shake, resulting in the stone falling off the lifting device, which poses a serious threat to the personal safety of workers. Therefore, those skilled in the art provide a stone lifting device for stone processing to solve the problems mentioned in the background art. Utility Model Content

[0026] The upper clamping plate 4 and the lower clamping plate 5 work together to fix and limit the position of the stone body 2, thereby achieving the purpose of fixing and limiting the position, enhancing the stability of the device, and effectively preventing it from swaying or shaking during movement.

[0027] Furthermore, two reinforcing frames 19 are fixedly connected to the outer surface of each set of casters 3. The upper surface of each set of reinforcing frames 19 is fixedly connected to the bottom surface of the movable frame 1. Through the reinforcing frames 19, the casters 3 and the movable frame 1 can be reinforced to prevent them from shifting in position during use.

[0028] Furthermore, a protective seat 6 is fixedly connected to the outer surface of each first hydraulic cylinder 10, and the bottom surface of each protective seat 6 is fixedly connected to the inner wall of the movable frame 1. Through the protective seat 6, the first hydraulic cylinder 10 can be protected, playing a strong protective role and preventing it from being damaged.

[0029] Furthermore, a protective shell 14 is fixedly connected to the outer surface of each second hydraulic cylinder 15. The two protective shells 14 are fixedly connected to the sides of the two sliding blocks 9 that are close to each other. The protective shells 14 can protect the second hydraulic cylinder 15 and effectively prevent it from being disturbed by external factors during use.

[0030] Furthermore, two dust covers 7 are fixedly connected to the outer surface of each group of third hydraulic cylinders 16. The bottom surface of each group of dust covers 7 is fixedly connected to the inner wall of the moving frame 1.

The outer surface of each set of reinforcing bolts 12 is threadedly connected to the inner wall of the sliding block 9. The reinforcing bolts 12 can reinforce the reinforcing plate 11 and the sliding block 9, preventing them from shifting in position during use.

[0034] Working principle: In use, the device is first moved above the stone to be lifted by the casters 3. Then, the extension end of the second hydraulic cylinder 15 is extended, which moves the clamping plate 13 to clamp the stone. The extension end of the third hydraulic cylinder 16 is extended, which moves the lower clamping plate 5 upward. This clamps and fixes the stone with the upper clamping plate 4. The position of the upper clamping plate 4 and the lower clamping plate 5 is restricted by the limiting bolts 8 and the limiting nuts 18 to achieve the purpose of fixing and limiting the clamped stone. By extending the extension ends of the first hydraulic cylinder 10 and the third hydraulic cylinder 16 together, the stone is lifted, thus achieving the purpose of stone lifting. This effectively avoids the problem that the lifting device is easily affected by road conditions during movement, causing the lifting device to sway and shake, resulting in the stone falling off the lifting device and posing a serious threat to the personal safety of workers.
