Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 In an embodiment of the utility model, a steel structure drilling device includes:

[0030] A workbench 1, wherein four corners of the workbench 1 are fixed with pillars for standing on the ground;

[0031] A gantry 10, both ends of which are fixed on the workbench 1, and the gantry 10 is made of steel;

[0032] The mobile frame 4 and the gantry 10 are provided with a lifting assembly for moving the mobile frame 4 up and down;

[0033] The multi-head drilling rig 14 is a prior art, and its specific structure and working principle are not described in detail here. The multi-head drilling rig 14 adopts a multi-drill design, and can drill multiple positioning and mounting holes on the plate surface of the plate-shaped steel structure at one time. The multi-head drilling rig 14 is installed on the mobile frame 4 as a whole. The table surface of the workbench 1 is provided with a through opening 11, and the through opening 11 is located directly below the multi-head drilling rig 14. When the multi-head drilling rig 14 drills, it can directly drill through the plate-shaped steel structure. The setting of the through opening 11 is to prevent the drilling rig from drilling through the workbench 1;

[0034] A discharge box 6 is located at the rear side of the gantry 10, and the discharge box 6 is fixed to the workbench 1. A discharge port 22 is provided at the front side of the bottom of the discharge box 6. A push plate 9 is slidably inserted at the rear side of the bottom of the discharge box 6. A connecting frame 8 is fixed to the rear side of the push plate 9. A connecting rod 7 is installed between the connecting frame 8 and the moving frame 4 for common rotation.

[0035] Wherein, a notch 15 is provided on the front side of the workbench 1;

[0036] In the present invention, the plate-shaped steel structures are stacked and placed inside the discharge box 6. Figure 1 This is the initial state of the entire device. When drilling, the mobile frame 4 moves upward through the lifting assembly, and the mobile frame 4 uses the connecting rod 7 and the connecting frame 8 to make the push-out plate 9 push the plate-shaped steel structure at the bottom position of the discharge box 6 out of the bottom discharge port 22. When the mobile frame 4 moves to the top, the plate-shaped steel structure is pushed to the bottom of the mobile frame 4, and the mobile frame 4 moves downward through the lifting assembly, and the push-out plate 9 is reset. The multi-head drill 14 on the mobile frame 4 drills holes in the plate-shaped steel structure. When the push-out plate 9 is completely reset, the plate-shaped steel structure inside the discharge box 6 falls again. After drilling is completed, continue to repeat the above steps and push in a new plate-shaped steel structure. The new plate-shaped steel structure pushes the plate-shaped steel structure after drilling to the recess 15. Since the plate-shaped steel structure after drilling is unbalanced due to the imbalance of the center of gravity, it falls from the recess 15.

[0037] Specifically, the lifting assembly includes a guide structure, which includes a guide rod 3. Slide grooves 2 are provided on the outer sides of both ends of the gantry 10, and two groups of guide rods 3 are vertically arranged and respectively fixed in the two slide grooves 2. The moving frame 4 is slidably sleeved on each group of guide rods 3.

[0038] In the present invention, the guide structure is provided to enable the moving frame 4 to move linearly up and down only in the gantry 10 .

[0039] Specifically, the lifting assembly further includes a screw lift 5, one end of the screw of the screw lift 5 is mounted on the moving frame 4, and the housing of the screw lift 5 is mounted on the top of the gantry 10;

[0040] In the present utility model, the screw lift 5 is a prior art, and its specific structure and working principle are not described in detail here.

[0041] Specifically, extrusion blocks 13 are provided at the bottom positions of both ends of the gantry of the gantry 10, and multiple reset structures are provided between the extrusion blocks 13 and the gantry 10. Inclined blocks 12 are fixed at both ends of the mobile frame 4, and the top of the extrusion block 13 is provided with an inclined surface consistent with the inclination of the inclined block 12. The reset structure includes a slide bar 16, a limit plate 20 and a reset spring 19. One end of the slide bar 16 is fixed to the gantry 10, and the other end of the slide bar 16 is fixed to the limit plate 20. Multiple countersunk holes 21 are provided on the outer side of the extrusion block 13, and the slide bar 16 is slidably inserted in the small hole of the countersunk hole 21. The reset spring 19 is located in the large hole of the countersunk hole 21, and the reset spring 19 is sleeved on the slide bar 16.

[0042] In the utility model, during the downward movement of the mobile frame 4, the inclined block 12 on the mobile frame 4 contacts the extrusion block 13, and the two inclined blocks 12 on the mobile frame 4 push the two extrusion blocks 13, and the extrusion blocks 13 approach each other until the extrusion blocks 13 contact the plate-shaped steel structure, thereby fixing the plate-shaped steel structure.

[0043] Specifically, the bottoms of both ends of the extrusion block 13 are provided with square notches, a right-angle block 17 is arranged inside the square notch, and the right-angle end of the right-angle block 17 is rotatably installed in the square notch, and an ejection spring 18 is fixed to one end of the right-angle block 17 and the inner wall of one side of the square notch;

[0044] In the present invention, during the contact between the extrusion block 13 and the plate-shaped steel structure, one end of the right-angle block 17 is pushed into the square notch by the plate-shaped steel structure, and the other ends of the four right-angle blocks 17 are respectively in contact with the four corners of the plate-shaped steel structure, thereby achieving centering and fixing of the plate-shaped steel structure.

[0045] Working principle: The plate-shaped steel structure is stacked and placed inside the discharge box 6. Figure 1This is the initial state of the entire device. When drilling, the mobile frame 4 moves upward through the lifting assembly. The mobile frame 4 uses the connecting rod 7 and the connecting frame 8 to make the push plate 9 push the plate-shaped steel structure at the bottom position of the discharge box 6 out of the bottom discharge port 22. When the mobile frame 4 moves to the top, the plate-shaped steel structure is pushed to the bottom of the mobile frame 4. The mobile frame 4 moves downward through the lifting assembly, and the push plate 9 is reset. The multi-head drill 14 on the mobile frame 4 drills holes in the plate-shaped steel structure. During the downward movement of the mobile frame 4, the inclined block 12 on the mobile frame 4 contacts the extrusion block 13, and the two inclined blocks 12 on the mobile frame 4 push the two extrusion blocks 13, and the extrusion block 1 3 are close to each other until the extrusion block 13 contacts the plate-shaped steel structure, thereby fixing the plate-shaped steel structure. During the contact process between the extrusion block 13 and the plate-shaped steel structure, one end of the right-angle block 17 is pushed into the square notch by the plate-shaped steel structure, and the other ends of the four right-angle blocks 17 contact the four corners of the plate-shaped steel structure respectively, thereby realizing the centering and fixing of the plate-shaped steel structure. When the push-out plate 9 is completely reset, the plate-shaped steel structure inside the discharge box 6 falls down again. After the drilling is completed, the above steps are repeated to push in a new plate-shaped steel structure. The new plate-shaped steel structure pushes the plate-shaped steel structure after the drilling is completed to the notch 15. Since the plate-shaped steel structure after the drilling is completed has an unbalanced center of gravity, it falls from the notch 15.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
