The roller 6 is moved laterally out of the notch 4 by the power unit 9, and then lifted by the power unit 9 until the upper cross-section of the roller 6 is above the conical protrusion 3. This arrangement can lift the workpiece, thereby separating the workpiece from the conical protrusion 3, so that the workpiece can avoid being scratched by contact with the conical protrusion 3 during movement.

[0035] The rollers 6 are divided into two groups, the center line of one group of rollers 6 is parallel to the center line of the fixed rod 7, and the center line of the other group of rollers 6 is perpendicular to the center line of the fixed rod 7. This arrangement can facilitate the movement of the workpiece in different directions. In order to achieve the same purpose, the upper surface of the fixed frame 5 can be inlaid with balls.

[0036] The power unit 9 includes a plug-in block 901 fixedly connected to the fixing rod 7, a plug-in slot 902 with a bottom penetrating therethrough is provided on the surface of the plug-in block 901, a clamping block 903 is inserted inside the plug-in slot 902, and plug-in holes 904 are provided on both sides of the bottom end of the plug-in block 901 at the plug-in slot 902. Through such an arrangement, the plug-in block 901 can be moved laterally, and after reaching the vertical moving position, the clamping block 903 and the plug-in block 901 can be separated during the vertical movement process, thereby realizing vertical movement. A connecting plate 905 is fixedly installed on the outer surface of the clamping block 903, and the connecting plate 905 is slidably connected to the side plate 2 through a limit frame 906. The outer side of the connecting plate 905 is fixedly installed A rack plate 907 is installed, and a power source 908 that drives the rack plate 907 to slide is fixedly installed on the outer side of the side plate 2. The power source 908 includes a motor and a gearbox and a gear meshing with the rack plate 907.

The free end of the telescopic sleeve 909 is two plug-in rods 910, and the plug-in rods 910 are plugged into the inside of the plug-in hole 904. When the plug-in rods 910 are inserted into the inside of the plug-in hole 904, they can drive the plug-in block 901 to move up and down. When the plug-in block 901 moves to the bottom, the plug-in rod 910 continues to move downward, so that the plug-in block 901 and the plug-in rod 910 can be separated.

[0037] The plug-in slot 902 is divided into two sections of plug-in slots of different sizes, and the clamping blocks 903 are arranged into two groups of different sizes. The two groups of clamping blocks 903 of different sizes correspond to the horizontally arranged roller 6 and the vertically arranged roller 6 respectively. The connecting plate 905 is divided into two groups, and the two groups of connecting plates 905 move independently. The two groups of connecting plates 905 are respectively connected to the large clamping block 903 and the small clamping block 903. Through such a setting, the power unit 9 can be used to control the movement of the two groups of rollers 6 separately.

[0038] Threaded columns 911 are provided at both ends of the fixing rod 7, and the outer surface of the threaded column 911 is threadedly connected to a square slider 912, the square slider 912 is slidably connected to the inside of the slide groove 8, and the plug-in block 901 is threadedly connected to the end surface of the threaded column 911. Such a setting can facilitate the installation of the square slider 912 and the plug-in block 901.

[0039] A support seat 10 is provided below the base plate 1, and a through hole 11 is opened in the middle of the base plate 1. The through hole 11 is located below the fixed rod 7 after the lateral movement. A telescopic rod 12 is fixedly installed at the bottom end of the support seat 10, and the free end of the telescopic rod 12 is located inside the through hole 11. The telescopic rod 12 is divided into two groups, and the two groups of telescopic rods 12 move synchronously with the large clamping block 903 and the small clamping block 903 respectively. The fixed rod 7 can be supported by the extension and retraction of the telescopic rod 12, thereby preventing the fixed rod 7 from bending.

[0040] The side panel 2 is plugged into the bottom panel 1 and fixedly connected by bolts. The support seat 10 is plugged into the bottom panel 1 and fixedly connected by bolts. Through such an arrangement, the side panel 2 and the support seat 10 can be disassembled, so that the bottom panel 1 can be easily exposed for cleaning.

[0041] Guide rails 13 are respectively arranged on the vertical sides of the base plate 1, and a sliding table 14 is arranged above the guide rails 13. The sliding table 14 is located above the base plate 1, and a laser cutting device 15 is fixedly installed on the free end of the sliding table 14. By setting a movable laser cutting device 15, the steel structure can be cut. Similarly, the laser cutting device 15 is fixed, and the steel structure is supported by a movable sliding bracket and driven to move the steel structure, which can also achieve the effect of laser cutting of the steel structure. In the scheme where the sliding bracket drives the steel structure to move, the base plate 1 only needs to be fixedly set below the laser cutting device 15.

[0042] The top of the conical protrusion 3 is a square cone, and the bottom is a rectangle. The notch 4 is opened from the bottom of the base plate 1 to the bottom of the square cone. The base plate 1 and the conical protrusion 3 are cast as a whole. After the casting is completed, a notch 4 is opened from the bottom of the base plate 1 to penetrate the base plate 1 and semi-penetrate the conical protrusion 3, so as to facilitate the production of the conical protrusion 3 and the base plate 1.

[0043] When in use, the base plate 1 is set below the steel structure to be cut, and the steel structure is supported by the conical protrusion 3. During the cutting process, slag can fall on the outer surface of the adjacent conical protrusion 3. When the position of the steel structure needs to be adjusted, the power unit 9 pushes the plug-in block 901 to move horizontally, and the fixed frame 5 and the roller 6 are moved out of the notch 4 of the conical protrusion 3. The roller 6 and the fixed frame 5 are lowered and moved upward under the action of the telescopic sleeve 909, so that the upper cut surface of the roller 6 is located above the conical protrusion 3, and the steel structure is supported by the roller 6, so that the steel structure is separated from the conical protrusion 3, which facilitates the sliding of the workpiece and prevents the friction between the steel structure and the conical protrusion 3 from scratching the surface of the workpiece.
