Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a drilling device for steel structure foundations in construction engineering. Background Technology

[0002] Steel structures are structural systems constructed from steel materials such as structural steel sections and plates through welding and bolting. They possess significant advantages such as high strength, light weight, good overall rigidity, and strong deformation capacity, making them widely used in construction projects such as high-rise buildings, large-span stadiums, industrial plants, and bridge engineering. The steel structure foundation, as a crucial transitional component connecting the upper steel columns and the concrete foundation, directly affects the safety and stability of the entire structure due to its processing quality. Drilling is a critical step in the processing of the steel structure foundation. Multiple sets of anchor bolt holes are typically drilled on the foundation for precise alignment and fixation with anchor bolts pre-embedded in the concrete foundation. The accuracy of these bolt hole diameters, positional deviations, and hole wall quality directly determine the installation accuracy and load-bearing performance of the steel structure foundation. Excessive drilling deviations will lead to difficulties in on-site installation, potentially requiring hole enlargement or reprocessing, severely impacting construction progress and project quality.

[0003] After drilling, existing drilling equipment often leaves a large number of burrs and metal debris on the edge of the hole. Especially when the drill bit penetrates the lower surface of the workpiece, the remaining material is very thin. The axial force of the drill bit is no longer offset, but instead pushes this thin metal downwards, forming a solid, thick, and firmly connected large flange burr. These burrs not only affect the aesthetics of the hole, but may also hinder the smooth insertion of subsequent bolts, or cause the burrs to fall off due to vibration during long-term use, affecting the stability of the preload of the connection pair. Summary of the Invention

[0021] In use, the workpiece to be processed is placed in the positioning groove 62. Then, the third electric slide rail 64 on one side of the placement table 61 is opened. The electric slider inside the third electric slide rail 64 drives the connecting rod 610 to move. The connecting rod 610 drives the pressing roller 65 to move until the pressing roller 65 moves to the fixed point above the workpiece.

A conical grinding head 687 is fixedly connected to the top of the rotating column 686. An annular grinding plate 688 is fixedly connected to the outer side of the rotating column 686 via a bracket.

[0027] The fixed end of the second electric telescopic rod 682 is fixedly connected to one side of the limit frame 611. A grinding disc is installed on the top of the annular grinding plate 688, and the annular grinding plate 688 is sleeved on the outside of the conical grinding head 687.

[0028] The cleaning device 69 includes a filter cartridge 691. A vacuum pump 692 is connected to one side of the filter cartridge 691. Both ends of the filter cartridge 691 are connected to bends 693. The end of the bend 693 away from the filter cartridge 691 is connected to a corrugated pipe 694. The corrugated pipe 694 at one end of the filter cartridge 691 is connected to a first air inlet pipe 695. The corrugated pipe 694 at the other end of the filter cartridge 691 is connected to a second air inlet pipe 696. One end of the first air inlet pipe 695 is connected to an annular air supply pipe 697. Air inlets 698 are evenly connected to the bottom of the annular air supply pipe 697. One end of the second air inlet pipe 696 is connected to an annular dust suction pipe 699. A dust collection pipe 6910 is evenly connected to the outside of the annular dust suction pipe 699. Dust inlets 6911 are evenly opened on the outside of the dust collection pipe 6910.

[0029] The filter cartridge 691 has a material inlet on its outer side and a filter assembly is installed inside the filter cartridge 691. The outer side of the annular air supply pipe 697 is fixedly connected to the top of the annular plate 671 through a bracket, and the outer side of the annular dust suction pipe 699 is fixedly connected to the outer side of the reinforcing plate 684 through a bracket.

[0030] In use, after drilling is completed, the lifting assembly 9 drives the drilling assembly 10 to rise, opening the third electric slide rail 64 on the other side of the placement platform 61 to move the limit frame 611. When the limit frame 611 moves, it drives the push plate 675 to move through the first electric telescopic rod 676. The push plate 675 drives the drive motor 672 to move through the annular plate 671. Turning on the drive motor 672 can drive the rotating rod 673 and the grinding disc 674 to rotate. The rotating grinding disc 674 can remove the rolled edge generated on the upper surface of the workpiece when the drill bit enters the workpiece surface for drilling. It can remove the rolled edge in a timely and accurate manner, making the edge of the hole flat and smooth, avoiding the difficulty of subsequent bolt insertion or manual secondary repair due to the rolled edge residue, and significantly improving the surface quality of the base hole.

[0031] The second electric telescopic rod 682 is activated to move the base plate 681, aligning it coaxially with the grinding disc 674. Then, the third electric telescopic rod 683 is activated, extending and pushing the reinforcing plate 684 to bring the conical grinding head 687 to the workpiece's drilling location. The rotary motor 685 is then activated, driving the rotating column 686 to rotate. The rotating column 686 then rotates the conical grinding head 687 and the annular grinding plate 688 together. The conical grinding head 687 extends into the hole to remove large burrs connected to the base material, while the annular grinding plate 688 grinds the drilling location on the lower surface of the workpiece. This targeted removal of large burrs on the lower surface of the workpiece, combined with the deburring device 67, allows for simultaneous removal of burrs from both the upper and lower end faces of the workpiece after drilling, improving surface smoothness.

[0032] When the grinding disc 674, conical grinding head 687, and annular grinding plate 688 are grinding, the air pump 692 is turned on. The air pump 692 extracts the gas inside the filter cylinder 691 and draws the dust generated by the grinding disc 674, conical grinding head 687, and annular grinding plate 688 during the grinding process into the annular air supply pipe 697 and annular dust suction pipe 699 through the air inlet 698 and dust inlet 6911, respectively. The drawn-in dust is finally discharged into the filter cylinder 691 and filtered, which can absorb the dust generated during grinding in a timely manner and prevent the dust from spreading and affecting the working environment.

[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
