[0002] Steel structures are structures made of steel materials and are widely used building materials. During the processing of steel structures, cutting equipment is needed to cut the steel structures into the required shapes and sizes. Cutting equipment is a very important piece of equipment in the steel structure processing process. As disclosed in announcement number CN212599416U, a steel structure cutting device relates to the field of steel structure technology. This steel structure cutting device includes a worktable. Two vertical plates are fixedly connected to the upper surface of the worktable. The upper ends of the two vertical plates are fixedly connected by a horizontal plate. A movable plate is positioned between the two vertical plates below the horizontal plate. The upper surface of the movable plate is fixedly connected to the bottom surface of the horizontal plate by a hydraulic cylinder. A cutting mechanism is fixedly connected to the right side of the movable plate. A threaded rod is positioned on the left side of the front vertical plate, with its bottom end rotatably inserted into the upper surface of the worktable. This steel structure cutting device, by incorporating a threaded rod, internal and external double gears, a driven gear, a friction wheel, and a ratchet, achieves the effect of moving the steel structure during the rotation of the friction wheel. This solves the problem of low cutting efficiency in current cutting devices, which require movement after each section is cut. However, existing technologies have the problem that most cutting devices directly cut the steel structure, making it inconvenient to adjust the cutting depth and move and transport the steel structure. For example, the comparative patents listed above have this problem. To address this issue, we propose an adjustable cutting depth steel structure cutting device. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-6 .
[0016] To address the problems in existing technologies where most cutting devices directly cut the steel structure, making it inconvenient to adjust the cutting depth and move and transport the steel structure, this solution provides an adjustable cutting depth steel structure cutting device. The device includes a cutting table 1 and a cutting machine 5 positioned above the cutting table 1. The cutting machine 5 is mounted on the front end of a movable block 4, and the movable block 4 slides vertically between itself and a fixed frame 2 fixed to the rear end of the cutting table 1 and in a vertical position. Simultaneously, the movable block 4 drives the cutting machine 5 to move and lift above the cutting table 1. like Figure 1 , Figure 2 and Figure 3 As shown, firstly, according to the required cutting depth of the steel structure, the electric telescopic rod 3 installed on the upper end of the fixed frame 2 is activated. The output end of the electric telescopic rod 3 is fixedly connected to the movable block 4. The electric telescopic rod 3 pushes the movable block 4 to slide up and down in the fixed frame 2. The cutting machine 5 is installed at the front end of the movable block 4. The movable block 4 drives the cutting machine 5 to rise and fall above the cutting table 1, which facilitates the adjustment of the height of the cutting machine 5. At the same time, the rear end of the movable block 4 is fixedly connected to the pointer block 6. The movable block 4 drives the pointer block 6 to form an up and down sliding structure with the fixed frame 2, which improves the stability of the movable block 4 during movement. At the same time, the pointer block 6 points to the scale 7 at the rear end of the fixed frame 2 to observe the height of the cutting machine 5 and adjust the cutting machine 5 to the corresponding height. After height adjustment, the steel structure to be cut is placed on the upper end of the conveyor plate 8, with one side of the steel structure attached to the left side of the auxiliary plate 10. The conveyor plate 8 moves back and forth on the upper end of the cutting table 1, and a limiting mechanism for fixing the steel structure is provided on the upper end of the conveyor plate 8. The limiting mechanism consists of clamping side plates 11 symmetrically arranged on the front and rear sides of the upper end of the fixing frame 2, a connecting bolt 15 for adjustment, and a fixing clamping plate 16 rotatably connected to the lower end of the connecting bolt 15 for pressing the steel structure. Figure 4 , Figure 5 and Figure 6 As shown, by rotating the fixed sleeve 14 threaded to the outer surface of the fixed rod 13, the fixed sleeve 14 and the movable rod 12 are fitted together, thereby pushing the movable rod 12 to slide back and forth between the fixed rod 13. At the same time, the movable rod 12 slides with the auxiliary plate 10, causing the movable rod 12 to push the clamping side plate 11 to move closer to the steel structure. The clamping side plate 11 clamps and positions the side of the steel structure, which is convenient for stable clamping of steel structures of different sizes. Then, by rotating the connecting bolt 15 threaded to the upper end of the clamping side plate 11, the lower end of the connecting bolt 15 is rotatably connected to the fixed clamping plate 16. The connecting bolt 15 drives the fixed clamping plate 16 to move downward to press and position the steel structure, thereby stably clamping the steel structure and improving the stability of the steel structure during the cutting process. After clamping, the feeding plate 8 is slowly moved to the left. The feeding plate 8 slides between itself and the linear guide rail 9, which drives the steel structure to move and feed. When the steel structure comes into contact with the blade in front of the cutting machine 5, cutting is achieved. Since the cutting machine 5 has been adjusted to the appropriate height, the cutting depth of the steel structure can be controlled. Moreover, the upper end of the feeding plate 8 is flush with the upper end of the support roller 17, which is rotatably connected to the left end of the cutting table 1. The cut steel structure comes into contact with the support roller 17, which drives the support roller 17 to rotate on the left end of the cutting table 1, improving the stability of the steel structure during movement.
