Description

Technical Field

[0001] This utility model belongs to the field of building engineering, specifically a new type of floor slab drilling device. Background Technology

[0002] In building construction projects, during the decoration and renovation or water and electricity installation phases, a large number of water and electrical conduits, fire protection pipes, cable trays, air ducts, and decorative ceiling joists are laid out under the floor slab ceiling. The hangers and brackets that fix and support them are often installed by drilling holes in the concrete structure of the floor slab ceiling and inserting expansion bolts. For vertical drilling of floor slab ceilings, the most common drilling method on construction sites is for workers to stand on A-frame ladders or simple trestles and drill directly with a handheld drill. This drilling method requires workers to keep their heads up and work continuously, which is not only easy to cause fatigue, but also easy to drill crookedly, resulting in low drilling efficiency and the inhalation of a lot of dust. At the same time, workers standing on A-frame ladders or simple trestles pose a risk of falling. Therefore, we have designed a new type of floor slab drilling device. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A novel floor slab drilling device, such as Figure 1 , 2 As shown in Figures 3 and 4, the system includes a base 1. Several support wheels 8 are rotatably mounted on the bottom of the base 1. An electric push rod 2 is fixedly mounted on the base 1. A drilling machine 3 is fixedly mounted on the top of the electric push rod 2. A dust collection box 4 is detachably mounted on the electric push rod 2. The dust collection box 4 is arranged around the drilling machine 3 and contacts and cooperates with the main body of the drilling machine 3. L-shaped rods 6 are slidably mounted on both sides of the dust collection box 4 through rings 5. The outer circumference of the rings 5 ​​is fixedly mounted on the dust collection box 4, and the inner circumference of the rings 5 ​​is slidably fitted on the L-shaped rods 6. The tops of the rings 5 ​​and the L-shaped rods 6 are elastically connected by springs 7. The springs 7 are fitted on the outer circumference of the vertical part of the L-shaped rods 6. One end of the springs 7 abuts against the rings 5, and the other end of the springs 7 abuts against the junction of the horizontal and vertical parts of the L-shaped rods 6. This utility model has a simple structure and ingenious design. By setting an extendable electric push rod 2, operators can operate the drilling while standing on the ground. The dust collection box 4 can collect the dust that falls during drilling, preventing harm to the operator's health. The L-shaped rod 6 can increase the stability of drilling and prevent the drill 3 from shaking and causing the drill to go astray. It meets market demand and is suitable for promotion. When using this utility model, first push the base 1 to move the device to the floor slab where drilling is needed. By controlling the extension of the electric push rod 2, the movable end of the electric push rod 2 drives the drill 3, dust collection box 4 and L-shaped rod 6 to move upward. The top of the L-shaped rod 6 first contacts the floor slab and abuts against it. When the drill 3 is started to drill, the movable end of the electric push rod 2 will drive the drill 3, dust collection box 4 and ring 5 to continue to move upward. The spring 7 is compressed. At this time, the L-shaped rod 6 can prevent the drill 3 from shaking from side to side. The dust generated during drilling falls into the dust collection box 4 below and is collected. After drilling is completed, the dust collection box 4 can be removed for unified dust disposal, making it convenient to use.

[0017] Specifically, as shown in the figure, the L-shaped rod 6 in this embodiment has an L-shaped through-slot 20 inside. The bottom end of the L-shaped rod 6 is fixedly connected to a corrugated pipe 23. The top of the electric push rod 2 is fixedly installed with a vacuum cleaner 21. The suction port of the vacuum cleaner 21 is fixedly connected to the corresponding corrugated pipe 23 through a three-way pipe 22. The dust collection box 4 can collect larger gravel particles generated during work. During drilling, a lot of dust and dirt will also be diffused in the air, which will also be harmful to the health of the workers below. By using the vacuum cleaner 21, the dust and dirt generated during drilling can be sucked into the vacuum cleaner 21 in a timely manner through the L-shaped through-slot 20, the corrugated pipe 23, and the three-way pipe 22, which is convenient for use.

[0018] Specifically, as shown in the figure, in this embodiment, two dust collection boxes 4 are provided and arranged on both sides of the drilling rig 3. A circular groove 30 is provided in the middle of the dust collection box 4. The main body of the drilling rig 3 is placed in the circular groove 30 and fits snugly with the circular groove 30. Two fixing plates 31 are fixedly provided at the top of the electric push rod 2. Dovetail grooves 32 are respectively opened on the fixing plates 31. Dovetail sliders 33 are slidably fitted in the dovetail grooves 32. The dovetail sliders 33 are respectively fixedly installed on the corresponding dust collection boxes 4. Threaded holes 34 are respectively opened on the dovetail grooves 32 and the dovetail sliders 33. The same bolt 35 is threadedly installed on the corresponding threaded holes 34. By removing the bolt 35, the limitation on the dovetail sliders 33 can be released, and the dovetail sliders 33 can slide out from the dovetail grooves 32, thereby removing the dust collection box 4 and facilitating the cleaning of the dust in the dust collection box 4.

[0019] Furthermore, as shown in the figure, a retaining ring 40 is fixedly fitted at the bottom of the L-shaped rod 6 in this embodiment. The retaining ring 40 can prevent the ring 5 from falling off the L-shaped rod 6.

[0020] Furthermore, as shown in the figure, the top end of the L-shaped rod 6 in this embodiment is horizontal and is fixedly equipped with an anti-slip pad 50. The anti-slip pad 50 can increase the friction between the top end of the L-shaped rod 6 and the floor slab, preventing movement during drilling.

[0021] Furthermore, as shown in the figure, the support wheel 8 in this embodiment is a self-locking wheel. Locking the support wheel 8 during use facilitates operation and improves stability.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
