Description

Technical Field

[0001] This invention relates to the field of prefabricated wall panel drilling technology, specifically to a prefabricated wall panel drilling device for building decoration. Background Technology

[0002] In the actual construction and decoration of precast concrete wall panels, drilling is required to facilitate subsequent pipe installation and other operations. Precast wall panels are usually made of reinforced concrete and have internal rebar. After precasting, the panels are usually not finished, which places higher demands on the drilling quality. Currently, precast wall panel drilling equipment usually uses a core drill for direct drilling, which is widely used due to its high efficiency. However, direct drilling can easily cause edge breakage when the drill bit breaks through the concrete. It is not convenient to adapt to different concrete wall panel thicknesses, prompting workers to drill from both sides. It is also not convenient to assist workers in quickly locating and avoiding the rebar installation position. Direct drilling can also wear down the rebar and affect the structural strength of the precast concrete wall panel.

[0016] This invention uses a horizontal correction component in conjunction with a laser-assisted component to facilitate vertical drilling by workers, improve drilling accuracy, and provide guidance to ensure the verticality of the hole. At the same time, the use of a laser-assisted component in conjunction with a horizontal bubble allows workers to use laser assistance to stagger the rebar positions before drilling, which can further avoid drilling damage to the rebar and affecting the structural strength of the precast concrete wall panel. It also ensures smooth drilling and avoids obstruction by the rebar during drilling, which would require re-drilling and affect the quality of the process.

[0017] The indicator light allows the drill bit to provide visual feedback during the actual drilling process, indicating when the hole is nearing completion and prompting the user to switch to the next drilling side. This avoids edge chipping issues that can occur with direct drilling. The structure provides direct feedback and also utilizes the drill bit for positioning and pilot hole placement, ensuring the stability of the drill bit. Furthermore, the structure allows for accurate and direct feedback by drilling through a precast concrete wall panel into a test column. It also offers better adaptability, easily accommodating precast concrete wall panels of varying thicknesses, and is simple and flexible to use.

[0018] The combination of a handheld punch and a water spray unit allows for automatic water spraying to remove dust and cool the area during punching operations, reducing dust pollution. Furthermore, the structure employs a synchronous opening and closing mechanism between a solenoid valve and a drive motor, effectively preventing accidental forgetting to turn it on and ensuring timely dust removal.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 9 As shown:

[0031] This invention provides a technical solution: a precast wall panel drilling device for building decoration, comprising a drilling handheld component 1, a horizontal correction component 2 mounted on the drilling handheld component 1, and a laser auxiliary component 3 mounted on the horizontal correction component 2; the laser auxiliary component 3 is used to stagger the rebar installation; a drilling component 4 is mounted on the drilling handheld component 1; a prompting component 5 is mounted on the drilling component 4; the prompting component 5 is used to prompt double-sided drilling; a water spray component 6 is mounted on the drilling handheld component 1; the water spray component 6 is used for synchronous drilling and water spraying; the drilling handheld component 1 includes: a housing 101 and a control switch 102, the control switch 102 is fixedly mounted on the housing 101; a handle is provided on the side of the housing 101.

[0032] The drilling handheld device 1 further includes: a drive motor 103, which is fixedly installed inside the housing 101, and the output shaft of the drive motor 103 passes through the housing 101; a self-locking drill chuck is provided on the output shaft of the drive motor 103; the water spraying device 6 includes: a water spraying pipe 601, which is fixedly installed on the mounting plate 201; a nozzle is provided at the front end of the water spraying pipe 601; the water spraying pipe 601 is connected to a water source; the water source can be a water pump or a water storage tank; the nozzle at the end of the water spraying pipe 601 is aligned with the core drill 401; the water spraying device 6 also includes: a solenoid valve 602, which is fixed on the water spraying pipe 601. The device is equipped with a solenoid valve 602; the control switch 102 is electrically connected to the drive motor 103 and the solenoid valve 602. The drilling handpiece 1, together with the water spraying component 6, can automatically spray water to remove dust and cool down during drilling operations, reducing dust pollution. At the same time, this structure adopts a synchronous opening and closing method of the solenoid valve 602 and the drive motor 103, which can effectively avoid manual forgetting to turn it on, resulting in untimely dust removal and dust dispersion. The structure is simple to control and can be turned on automatically. When drilling is required, the manual pressing of the control switch 102 will start the drive motor 103 and open the solenoid valve 602.

[0033] The horizontal alignment component 2 includes a mounting plate 201 and a leveling bubble 202. The mounting plate 201 is fixedly mounted on the housing 101. The leveling bubble 202 is fixedly mounted on the mounting plate 201. The mounting plate 201 has hexagonal holes. The laser auxiliary component 3 includes a sliding column 301, a wall-mounted plate 302, and a laser lamp 303. The laser lamp 303 is a straight-line laser, and the sliding column 301 is a hexagonal column. The sliding column 301 is slidably inserted into the hexagonal holes on the mounting plate 201. Inside; a wall-mounted plate 302 is fixedly installed on the sliding column 301, and the wall-mounted plate 302 has an arc-shaped structure; a spring is sleeved on the sliding column 301, and the spring sleeved on the sliding column 301 is connected between the sliding column 301 and the wall-mounted plate 302; three laser lights 303 are fixedly installed on the wall-mounted plate 302, and the three laser lights 303 are distributed at a 90-degree angle; the wall-mounted plate 302 is used to adhere to the surface of the precast wall panel, and the use of a horizontal correction component 2 in conjunction with a laser auxiliary component 3 facilitates the work of personnel. The vertical drilling mechanism improves drilling accuracy and serves as a guide, ensuring the verticality of the hole. Simultaneously, the use of laser-assisted components 3 in conjunction with the horizontal water bubble 202 allows workers to avoid damaging the reinforcing bars during drilling, thus preventing damage to the precast concrete wall panel and ensuring smooth drilling. This avoids the need for re-drilling due to obstruction by the reinforcing bars, which would affect the quality of the process. The simple structure allows for quick positioning. When drilling is required, the wall panel 302 is first attached to the wall surface, and the horizontal water bubble 202 is kept level for initial horizontal correction. Then, three laser lights 303 are activated. The laser lights 303 are aligned with the cylindrical drill 401, ensuring the laser beams are positioned between the horizontal and vertical reinforcing bars of the precast concrete wall panel. This avoids the horizontal and vertical reinforcing bars, ensuring accurate drilling positions.

[0034] In Example 2, based on Example 1, the drilling component 4 includes: a barrel drill 401 and a positioning rod 402. The barrel drill 401 is clamped and installed on the self-locking drill chuck of the drive motor 103, and the barrel drill 401 has two through slots; the positioning rod 402 is threadedly connected to the barrel drill 401, and the positioning rod 402 has a wire hole and a battery; the positioning rod 402 and the barrel drill 401 are concentric; the barrel drill 401 is used to drill holes in precast wall panels; the drilling component 4 also includes: a drill bit 403 and an indicator light 404. The drill bit 403 is fixedly installed on the positioning rod 402; the drill bit 403 is used for pilot drilling; the indicator light 404 is fixedly installed on the positioning rod 402. 2. The indicator light 404 is located near two through slots on the barrel drill 401; the drill bit 403 protrudes from the front end of the barrel drill 401; the indicator element 5 includes: a detection post 501, which is slidably inserted into the positioning rod 402; the end of the detection post 501 has an arc-shaped structure; the detection post 501 is located on the front side of the barrel drill 401; a spring is sleeved inside the positioning rod 402, and the spring sleeved inside the positioning rod 402 is connected between the detection post 501 and the positioning rod 402; the detection post 501 protrudes from the positioning rod 402; the indicator element 5 also includes: an indicator switch 502, which is fixedly installed inside the positioning rod 402, and The indicator switch 502 is located below the detection column 501; the indicator switch 502, the battery inside the positioning rod 402, and the indicator light 404 are connected in series; the indicator switch 502 is located inside the spring inside the positioning rod 402; the indicator element 5 can provide a light indication during the actual drilling process of the barrel drill 401, indicating that the hole is close to being drilled through, and prompting the driller to change sides in time to avoid the problem of edge chipping that is easily caused by direct drilling through. This structure provides a direct indication, and the drill bit 403 also serves as a positioning pilot hole to ensure the drilling stability of the barrel drill 401. This structure allows the detection column 501, which can be drilled through the precast concrete wall panel first, to... The detection method provides accurate and direct feedback, while also offering better adaptability, making it suitable for precast concrete wall panels of varying thicknesses. It is simple and flexible to use; workers can simply hand-operate the drill. The compression detection column 501 is positioned in front of the cylinder drill 401. After the drill bit 403 passes through, the compression detection column 501 will first pass through the precast concrete wall panel, while the cylinder drill 401 has not yet penetrated. As the compression detection column 501 passes through the precast concrete wall panel, it is no longer pressed against the inner wall of the borehole. Under the pressure of the spring below the compression detection column 501, it will move upwards and reset, and the indicator light 404 will immediately turn off.

[0035] The working principle of this embodiment is as follows: First, when drilling is required, the wall panel 302 is attached to the wall surface. At this time, the leveling bubble 202 is kept horizontal for leveling. Then, the three laser lights 303 are turned on. Using the light emitted by the laser lights 303, the laser lights 303 are aligned with the cylindrical drill 401. The laser light emitted by the laser lights 303 is positioned at the interval between the horizontal and vertical ribs of the precast concrete wall panel. This avoids the horizontal and vertical ribs of the precast concrete wall panel, ensuring accurate drilling. Indeed, manually pressing the control switch 102 starts the drive motor 103 for drilling, simultaneously opening the solenoid valve 602 to allow water to flow through the water spray pipe 601. Water is then sprayed through the nozzle at the end of the pipe to assist in cooling and dust removal. The operator holds the casing 101 and pushes the drill bit 403 to first contact the wall surface for drilling. Then, the core drill 401 continues drilling while remaining flush with the wall. During this process, the mounting plate 201 slides on the sliding column 301, which guides the vertical movement. The spring on the sliding column 301 is gradually compressed. The wall panel 302 can be manually supported to adhere to the wall surface. As the drill bit 403 drills into the precast concrete wall panel, it moves the detection column 501 along with it. The arc-shaped structure at the end of the detection column 501 prevents jamming. The detection column 501 is squeezed by the inner wall of the drill hole created by the drill bit 403, causing it to retract and compress the spring below. This, in turn, triggers the pressure indicator switch 502 to illuminate the indicator light 404, indicating that the detection column 501 is being squeezed. Positioned in front of the cylinder drill 401, after the drill bit 403 has drilled through, the compression detection column 501 will first pass through the precast concrete wall panel. At this time, the cylinder drill 401 has not yet drilled through. When the compression detection column 501 passes through the precast concrete wall panel, it will no longer be pressed by the inner wall of the borehole. Under the compression of the spring below the compression detection column 501, the compression detection column 501 will move up and reset, no longer pressing the indicator switch 502. At this time, the indicator light 404 will go out directly to indicate that it is necessary to change the drilling side in time to ensure that the edge of the hole is smooth.
