[0019] like Figures 1-4 The present invention relates to a drilling device for construction engineering, comprising a drilling bench drill 1, a drilling arm 2 slidably connected to the drilling bench drill 1, a drilling rod 3 attached to the lower end of the drilling arm 2, a plate 4 to be drilled being placed on the base of the drilling bench drill 1, and the plate 4 to be drilled being positioned below the drilling rod 3. The drilling bench drill 1 can be made using existing technology. The present invention includes a limiting mechanism 5, which includes a fixed rod 501, a sliding sleeve 502, a ball bearing 503, a pressure plate 504, and a first spring 505. The upper end of the fixed rod 501 is fixedly connected to the drilling arm 2, and the fixed rod 501 is positioned to the side of the drilling rod 3. A top hole is provided on the top surface of the sliding sleeve 502. The lower end of the fixing rod 501 is slidably connected to the top hole of the sliding sleeve 502. A bottom hole is provided on the bottom surface of the sliding sleeve 502. A ball 503 is slidably and rollingly connected to the bottom hole of the sliding sleeve 502. The outer diameter of the ball 503 is larger than the inner diameter of the lower end of the bottom hole of the sliding sleeve 502. The lower part of the ball 503 extends out of the bottom hole of the sliding sleeve 502. A pressure plate 504 is slidably connected to the bottom hole of the sliding sleeve 502. The pressure plate 504 is located above the ball 503. The lower end of the first spring 505 is fixedly connected to the top surface of the pressure plate 504. The upper end of the first spring 505 is fixedly connected to the top wall of the bottom hole of the sliding sleeve 502.

[0020] The drilling arm 2 moves downward, driving the drilling rod 3 to move downward as well. The fixed rod 501 follows the drilling arm 2 downward. The ball 503 inside the sliding sleeve 502 is in contact with the plate 4 to be drilled. When the ball 503 contacts the plate 4, there is a small gap between the drilling rod 3 and the plate 4. Since the ball 503 can roll, the plate 4 can move to adjust the drilling position when the ball 503 contacts it. However, since the ball 503 is pressed against the plate 4 by the first spring 505, the movement of the plate 4 is restricted in a relatively free state, thus achieving precise determination of the drilling position of the plate 4. After the position of the plate 4 is adjusted to the correct position, the drilling arm 2 continues to move downward so that the drilling rod 3 contacts the plate 4 and completes the drilling. During the drilling process, the top surface of the bottom hole of the sliding sleeve 502 will compress the first spring 505.

[0021] The limiting mechanism 5 includes a movable plate 506, a pressing rod 507, a friction plate 508, and a second spring 510. The movable plate 506 is fixed to the lower end of the fixed rod 501 and is slidably connected to the top hole of the sliding sleeve 502. The upper end of the pressing rod 507 is fixedly connected to the bottom surface of the movable plate 506 and is located to the side of the ball 503. The sliding sleeve 502 has a hole for sliding connection, and the lower end of the pressing rod 507 extends out of the bottom surface of the sliding sleeve 502. The friction plate 508 is fixedly connected to the lower end of the pressing rod 507. The second spring 510 is sleeved on the outside of the pressing rod 507. The upper end of the second spring 510 is fixedly connected to the bottom surface of the movable plate 506, and the lower end of the second spring 510 is fixedly connected to the sliding sleeve 502. On the bottom surface of the top hole; the limiting mechanism 5 includes a limiting ring 509, which is fixedly connected to the upper end of the top hole of the sliding sleeve 502. The inner diameter of the limiting ring 509 is less than the outer diameter of the moving plate 506, and the inner diameter of the limiting ring 509 is greater than the outer diameter of the fixed rod 501. The fixed rod 501 passes through the limiting ring 509. Multiple extrusion rods 507 are provided on the bottom surface of the moving plate 506. The multiple extrusion rods 507 are evenly distributed around the axis of the moving plate 506. The sliding sleeve 502 has holes inside for multiple sliding sleeves 502 to slide and connect. The lower end of each extrusion rod 507 extends out of the bottom surface of the sliding sleeve 502. A friction plate 508 is fixedly connected to the lower end of each extrusion rod 507. A second spring 510 is sleeved on each extrusion rod 507. The friction plate 508 is made of rubber.

[0022] When the ball 503 contacts the plate 4 to be drilled, the drilling arm 2 continues to move downward so that the drilling rod 3 contacts the plate 4 to complete the drilling. At this time, the extrusion rod 507 moves downward and compresses the second spring 510. The extrusion rod 507 moves downward so that the lower end of the extrusion rod 507 extends out of the bottom surface of the sliding sleeve 502 and the friction plate 508 abuts against the plate 4 to be drilled, thereby fixing the plate 4 to be drilled and achieving stable drilling of the plate 4 to be drilled.

[0023] The limiting ring 509 is designed to prevent the moving plate 506 from coming out of the top hole of the sliding sleeve 502.

[0024] The two limiting mechanisms 5 are set to achieve stable fixation of the plate 4 to be perforated.

[0025] This utility model includes a dust collection mechanism 6, which includes a dust collection box 601, a support tube 602, and a protective cover 603. The dust collection box 601 is fixedly connected to the outer wall of the sliding sleeve 502. One end of the support tube 602 is fixedly connected to the side wall of the dust collection box 601. The protective cover 603 is fixedly connected to the end of the support tube 602 facing away from the dust collection box 601. The dust collection box 601 has a hollow interior. The protective cover 603 is located on the side of the drill rod 3 and has a semi-circular arc shape. The inner wall of the protective cover 603 faces the drill rod. 3. The inner wall of the protective cover 603 is provided with multiple air inlets. The support tube 602 is fixedly connected to the outer wall of the protective cover 603. The internal cavity of the dust collection box 601, the support tube 602 and the internal cavity of the protective cover 603 are connected. The side wall of the dust collection box 601 is connected to a dust collection device through a pipe. A filter screen is connected between the dust collection box 601 and the pipe connected to the dust collection device. There are two dust collection mechanisms 6. The dust collection boxes 601 of the two dust collection mechanisms 6 are fixedly connected to the outer walls of the two sliding sleeves 502 respectively. The two dust collection mechanisms 6 are symmetrical about the drill rod 3 at 180°.

[0026] The protective cover 603 surrounds both sides of the drill rod 3. The dust collection device provides suction to draw the debris generated during drilling into the cavity of the dust collection box 601 through the protective cover 603 and the support tube 602, thereby achieving centralized collection of debris. At the same time, the protective cover 603 can also serve as a protective measure to prevent debris from splashing and polluting the environment or causing injury to personnel.

[0027] A chip removal hole can be provided on the bottom surface of the dust collection box 601, and a cover plate can be provided to cover the chip removal hole to facilitate the removal of debris from the cavity of the dust collection box 601.
