Description

Technical Field

[0001] This utility model relates to the field of drilling technology in building construction, specifically a new type of multifunctional drilling device for building construction. Background Technology

[0002] Drilling equipment refers to a general term for equipment used to process holes in solid materials. Common drilling equipment includes electric drills and drilling machines. With the further development of processing technology, the efficiency of drilling equipment has also been greatly improved. Drilling equipment is an indispensable tool in the fields of construction, decoration and furniture repair. It can drill holes, tighten screws and punch holes, and can also handle various hard materials, such as the reinforcement of building beams, slabs, columns and walls. When using an electric drill, the feed motion needs to be completed by the pushing force of the human body. Hold the handle, press the appropriate force against the workpiece, and press the switch to drill.

[0003] The existing utility model with authorization announcement number CN220313777U discloses a drilling device for building construction, including a protective shell and a hydraulic mechanism. The hydraulic mechanism is installed on the top of the protective shell, and a drilling assembly is installed at the bottom of the hydraulic mechanism. A connecting block is installed on the side of the protective shell. The connecting block is connected to a rotating mechanism installed on a support frame. The support frame is installed on a support plate, and a support foot is installed at the bottom of the support plate.

[0004] The above technical solution involves installing a cooling assembly at the bottom of the protective casing, with a cooling tank mounted on the assembly. The cooling tank is filled with cooling water, which is pumped through inclined nozzles to cool the drill bit in the borehole, improving drilling efficiency and quality. However, this construction drilling device has a limited functionality; it cannot simultaneously remove debris from the hole, affecting the stability of the workpiece installation. This necessitates manual cleaning of the hole with a brush when installing expansion bolts or other components, increasing labor intensity and reducing the overall effectiveness of the drilling device.

[0005] Therefore, those skilled in the art have provided a novel multifunctional drilling device for building construction to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of multifunctional drilling device for building construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel multifunctional drilling device for building construction includes a dual-axis motor, with a special drill bit fixedly connected to the output end of the dual-axis motor, and a cleaning mechanism provided on the outside of the dual-axis motor.

[0009] The cleaning mechanism includes a motor support plate positioned below a dual-axis motor. Two air inlets and two air outlets are respectively opened on the outer surface of the special drill bit. A first sealed bearing and a second sealed bearing are respectively fitted onto the outer surface of the special drill bit. A bearing protective shell is fixedly connected to the outer surfaces of the first and second sealed bearings. An electric air pump is located on the back of the dual-axis motor. The other output end of the dual-axis motor is fixedly connected to the rotor of the electric air pump. An air inlet valve is fixedly connected to the air inlet end of the electric air pump, and an air outlet valve is fixedly connected to the air outlet end. A ventilation pipe is fixedly connected to the air outlet end of the air outlet valve, with the end of the ventilation pipe away from the air outlet valve penetrating the bearing protective shell and extending into the interior of the bearing protective shell.

[0010] As a further embodiment of this utility model: a bearing fixing block is fixedly connected to the outer surface of the bearing protective shell, and the bottom surface of the bearing fixing block is fixedly connected to the upper surface of the motor support plate.

[0011] As a further improvement of this utility model: a positioning block is fixedly connected to the bottom surface of the dual-axis motor, and the bottom surface of the positioning block is fixedly connected to the upper surface of the motor support plate.

[0012] As a further improvement of this utility model: a stabilizing block is fixedly connected to the bottom surface of the electric air pump, and the bottom surface of the stabilizing block is fixedly connected to the upper surface of the motor support plate.

[0013] As a further improvement of this utility model: four support columns are fixedly connected to the upper surface of the motor support plate, and a protective plate is fixedly connected to the top of the four support columns.

[0014] As a further improvement of this utility model: the upper surface of the protective plate and the bottom surface of the motor support plate are both fixedly connected to the drill handles, and the outer surfaces of the two drill handles are both fixedly connected to the anti-slip sleeves.

[0015] As a further improvement of this utility model: the air intake end of the air intake valve is fixedly connected to an air intake cover, and the outer surface of the air intake cover is provided with a plurality of air intake holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by incorporating a cleaning mechanism, allows the dual-axis motor to drive a special drill bit to drill holes in a building. Simultaneously, the other output of the motor drives the rotor inside an electric air pump, generating suction that draws in outside air through the inlet valve and then into a ventilation duct through the outlet valve. The high-pressure gas inside the ventilation duct then enters the special drill bit through the bearing housing and inlet, and is finally discharged through the outlet. This allows the high-pressure airflow to expel debris from the hole through the gap between the drill bit and the hole when the special drill bit is drilling inside the building. This provides the drilling device with a debris-cleaning function, eliminating the need for manual cleaning, reducing labor intensity, and enhancing the functionality and effectiveness of the drilling device.

[0024] Please see Figure 1-5 A new type of multi-functional drilling device for building construction includes a dual-axis motor 1, a special drill bit 2 fixedly connected to the output end of the dual-axis motor 1, the special drill bit 2 having a hollow internal structure, and a cleaning mechanism 3 provided on the outside of the dual-axis motor 1.

[0025] The cleaning mechanism 3 includes a motor support plate 301, which is located below the dual-axis motor 1. A positioning block 5 is fixedly connected to the bottom surface of the dual-axis motor 1. The bottom surface of the positioning block 5 is fixedly connected to the upper surface of the motor support plate 301. The bottom surface of the dual-axis motor 1 is firmly connected to the upper surface of the motor support plate 301 through the positioning block 5, ensuring that the dual-axis motor 1 is accurately positioned and preventing the position of the dual-axis motor 1 from shifting. This can effectively protect the bottom of the dual-axis motor 1 and avoid unnecessary damage.

[0026] The outer surface of the special drill bit 2 has two air inlets 302 and two air outlets 303 respectively. The outer surface of the special drill bit 2 is respectively fitted with a first sealed bearing 305 and a second sealed bearing 306. The outer surfaces of the first sealed bearing 305 and the second sealed bearing 306 are fixedly connected to a bearing protective shell 304. The outer surface of the bearing protective shell 304 is fixedly connected to a bearing fixing block 4. The bottom surface of the bearing fixing block 4 is fixedly connected to the upper surface of the motor support plate 301. The bearing protective shell 304 is stably connected to the motor support plate 301 through the bearing fixing block 4, ensuring that the first sealed bearing 305 and the second sealed bearing 306 will not rotate with the dual-axis motor 1.

[0027] An electric air pump 308 is provided on the back of the dual-shaft motor 1. The other output end of the dual-shaft motor 1 is fixedly connected to the rotor of the electric air pump 308. A stabilizing block 6 is fixedly connected to the bottom surface of the electric air pump 308. The bottom surface of the stabilizing block 6 is fixedly connected to the upper surface of the motor support plate 301. The stabilizing block 6 makes the electric air pump 308 firmly fixed on the motor support plate 301, ensuring the high efficiency of the electric air pump 308.

[0028] An air inlet valve 309 is fixedly connected to the air inlet end of the electric air pump 308, and an air outlet valve 310 is fixedly connected to the air outlet end of the electric air pump 308. Four support columns 7 are fixedly connected to the upper surface of the motor support plate 301, and a protective plate 8 is fixedly connected to the top of the four support columns 7. The motor support plate 301, the four support columns 7, and the protective plate 8 constitute a simple protective shell, which prevents the dual-shaft motor 1 from being directly exposed to the open environment and protects the dual-shaft motor 1.

[0029] The upper surface of the protective plate 8 and the bottom surface of the motor support plate 301 are both fixedly connected to the drill handle 9. The outer surfaces of the two drill handles 9 are fixedly connected to the anti-slip sleeves 10. With the drill handles 9 and the anti-slip sleeves 10, the construction personnel can use the device conveniently, which increases the ease of manual operation of the device.

[0030] The outlet end of the exhaust valve 310 is fixedly connected to a ventilation pipe 307. The end of the ventilation pipe 307 away from the exhaust valve 310 passes through the bearing protective shell 304 and extends into the interior of the bearing protective shell 304. The inlet end of the intake valve 309 is fixedly connected to an intake shroud 11. Several suction holes 12 are opened on the outer surface of the intake shroud 11. The intake shroud 11, together with the suction holes 12, can effectively isolate large external impurities without affecting the smooth intake of the intake valve 309, and prevent external impurities from entering the interior of the intake valve 309 and causing blockage.

[0031] The working principle of this utility model is as follows: In use, first connect the dual-axis motor 1 to an external power source. When drilling into structures such as building walls, simply hold the drill handle 9 with both hands using the anti-slip sleeve 10. Then, use the power provided by the dual-axis motor 1 to drive the special drill bit 2 to rotate, thus drilling into the building. During drilling, the other output end of the dual-axis motor 1 can drive the rotor inside the electric air pump 308 to rotate, causing the electric air pump 308 to generate suction. This draws in outside air through the air inlet valve 309 and air inlet cover 11, and then sends it into the ventilation pipe 307 through the air outlet valve 310. The high-pressure gas inside the ventilation pipe 307 can then enter the interior of the special drill bit 2 through the bearing protective shell 304 and air inlet 302. Combined with the special hollow structure inside the special drill bit 2, the gas ultimately passes through… The vent 303 discharges air outwards, allowing the special drill bit 2 to use high-pressure airflow to expel debris from the hole through the gap between the hole and the special drill bit 2 when drilling inside the building. This enables the construction drilling device to clean debris inside the hole, eliminating the need for manual cleaning by workers, reducing their labor intensity, and increasing the functionality and effectiveness of the construction drilling device. Finally, when the special drill bit 2 rotates, the first sealing bearing 305 and the second sealing bearing 306 work together to ensure that gas can smoothly pass through the bearing protective shell 304 into the air inlet 302 without affecting the smooth rotation of the special drill bit 2. At the same time, due to the sealing effect of the first sealing bearing 305 and the second sealing bearing 306, gas leakage through the gap can also be effectively prevented, ensuring the normal operation of the debris cleaning work inside the hole.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
