[0033] The working principle of the above embodiment is:

[0034] (1) The frame steel plate 16 to be cut is placed on the cutting table 6. By rotating the movable bolt 15, the movable bolt 15 can be separated from the currently corresponding positioning screw groove on the inner side of the movable rod 8, so that the movable rod 8 loses its limit. By pulling the movable pull handle 9, the right movable screw frame 10, the right movable screw rod 11, the right movable turning handle 12, the right rolling bearing 13 and the right movable clamping block 14 can be driven to move left and right in turn, so that the distance between the two movable clamping blocks 14 can be adjusted. The distance between the two movable clamping blocks 14 can be adjusted according to the length of the frame steel plate 16. After the positions of the two movable clamping blocks 14 are adjusted, the movable bolt 15 can be moved back to the currently corresponding positioning screw groove on the inner side of the movable rod 8 by rotating the movable bolt 15, so that the movable rod 8 and the right movable screw frame 10 can be re-limited, so as to clamp and fix frame steel plates 16 of different lengths.

[0035] (2) After the distance between the two movable clamping blocks 14 is adjusted according to the above principle, the two movable handles 12 can be rotated to drive the two movable screws 11 to rotate respectively. Because the two movable screw frames 10 are respectively threadedly connected to the two movable screws 11, the two rolling bearings 13 and the two movable clamping blocks 14 will be driven to move downward during the rotation of the two movable screws 11. During the downward movement of the two movable clamping blocks 14, they will fit with the frame steel plate 16, so that the frame steel plate 16 can be clamped and fixed, avoiding the frame steel plate 16 from shaking or deflecting during the cutting process, thereby ensuring the cutting effect of the frame steel plate 16.

[0036] (3) The hydraulic oil can be pumped into the inner side of the hydraulic rod 20 through the hydraulic pump 19, so that the hydraulic rod 20 can be driven, and the slitting knife 21 can be driven to move downward through the hydraulic rod 20. During the downward movement of the slitting knife 21, the frame steel plate 16 can be slit, thereby achieving the purpose of slitting the frame steel plate 16.

[0037] (4) When the position of the frame steel plate 16 needs to be adjusted, the threaded rod 2 can be driven to rotate by turning the manual handle 3. Since the threaded rod 2 is threadedly connected to the threaded block 4, the threaded rod 2 will drive the threaded block 4, the movable block 5, the cutting table 6 and the frame steel plate 16 to move left and right in turn during the rotation of the threaded rod 2. The position of the frame steel plate 16 can be adjusted according to the position where the frame steel plate 16 needs to be cut, thereby ensuring the position and effect of the cutting of the frame steel plate 16.

[0038] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of good clamping effect of the slitting device is achieved. The slitting device can be adjusted according to the length of the crane frame. The slitting device can clamp and fix crane frames of different sizes, thereby improving the clamping and fixing effect of the crane frame, ensuring the clamping effect of the crane frame, and improving the use efficiency and effect of the slitting device.
