Description

Technical Field

[0001] This application relates to the field of construction surveying instruments, and in particular to a laser positioning and laying-out instrument that can be operated by a single person. Background Technology

[0002] In the field of construction, setting out is a crucial basic procedure. Traditional methods mainly rely on manual stringing, chalk marking, or the use of ordinary laser levels. While these methods are low-cost, they have significant drawbacks: low accuracy, low efficiency, and heavy dependence on multiple people working together.

[0003] With the development of technology, a variety of solutions have emerged in the market: 1. Traditional ink line snapping method: Two people work together to snap ink with a line. The advantage is low cost, but the disadvantages are poor accuracy, low efficiency, and the ink line can easily pollute the environment.

[0004] 2. Ordinary laser level: It can project horizontal or vertical laser lines and has improved accuracy, but it still requires multiple people to adjust the position and angle of the instrument, and cannot achieve complex operation by a single person.

[0005] 3. High-precision instruments such as total stations: They have extremely high accuracy, but are expensive, complex to operate, and require professional technicians to operate, making them difficult to promote in small and medium-sized construction projects. Utility Model Content

[0006] In order to address the problems of low efficiency, reliance on multiple people, and high cost of high-precision equipment in existing wire laying techniques, this application provides a laser positioning wire laying device that can be operated by a single person.

[0007] The laser positioning and laying instrument that can be operated by a single person provided in this application adopts the following technical solution: it includes a fixed base, a fixed support set at the middle position of the lower end face of the fixed base, a horizontal calibration module set at the middle position of the upper end face of the fixed base, a support plate connected to the vertical surface of the fixed base, and a laser emitting module set on the support plate. The laser emitting module includes a protective housing disposed on one side of the support plate, an angle adjustment module disposed between the protective housing and the support plate, and a laser emitting assembly disposed on the protective housing; The horizontal calibration module is used to detect the horizontal state of the fixed base and output a horizontal signal, which is used to drive the protective housing to rotate to adjust the projection angle of the laser emitting assembly.

[0008] By adopting the above technical solution, after the mounting base is installed, the leveling module detects its levelness and transmits the status information to the angle adjustment module via an electrical signal. The angle adjustment module then drives the protective housing to rotate based on the levelness information, adjusting the projection angle of the laser emitting component to ensure the laser is accurately aligned with the target position.

[0009] As a preferred embodiment, the angle adjustment module includes support seats fixedly disposed on both sides of the support plate, a worm gear rotatably connected to the support seats, a worm wheel meshing with the worm gear, a rotating shaft connected to the worm wheel, and a drive motor for driving the worm gear. The other end of the rotating shaft passes through the support plate and is connected to the protective housing, and the rotating shaft is fixedly connected to the protective housing. A sealed bearing is provided at the connection between the rotating shaft and the support plate. The drive motor is a stepper motor, and the output shaft of the drive motor is connected to the worm gear.

[0010] By adopting the above technical solution, the drive motor drives the worm to rotate via its output shaft. The worm wheel meshes with the worm, allowing the rotation of the worm to be transmitted to the worm wheel, which in turn drives the rotating shaft to rotate. One end of the rotating shaft is connected to the worm wheel, and the other end passes through the support plate and is connected to and fixed to the protective housing, ensuring that the rotation of the protective housing is synchronized with the rotation of the worm wheel. A sealed bearing is installed at the connection between the rotating shaft and the support plate to reduce friction during rotation and ensure sealing. The drive motor is a stepper motor, whose output shaft is directly connected to the worm. By precisely controlling the number of steps of the stepper motor, the precise rotation of the worm is achieved.

[0011] As a preferred embodiment, the laser emitting assembly includes a horizontal laser diode for emitting horizontal laser lines, a vertical laser diode for emitting vertical laser lines, and a laser emitting port disposed relative to the horizontal and vertical laser diodes, the laser emitting port being used to guide the laser lines emitted by the horizontal and vertical laser diodes; The horizontal and vertical laser diodes are configured as red laser tubes with a wavelength of 650nm and a power of 5mW, producing clear light spots that meet safety standards.

[0012] By adopting the above technical solution, both the horizontal and vertical laser diodes use red laser tubes with a wavelength of 650nm and a power of 5mW. This configuration ensures a clear light spot that meets safety standards and is suitable for various laser measurement and positioning applications. The laser emission port plays a crucial role, guiding the laser lines emitted by the horizontal and vertical laser diodes to ensure that the laser lines are accurately pointed at the target.

[0013] As a preferred embodiment, the horizontal calibration module is an electronic bubble sensor, and the electronic bubble sensor is a digital tilt sensor.

[0014] By adopting the above technical solution, the digital tilt sensor can output the tilt angle of the device in the form of a digital signal, thereby achieving high-precision horizontal calibration. In practical applications, this sensor can fix the tilt state of the mounting base in real time and transmit the data to the control circuit for processing.

[0015] As a preferred embodiment, the fixed support is a magnetic base, and the magnetic base has a built-in permanent magnet.

[0016] By adopting the above technical solution, this utility model can be adsorbed onto the metal surface.

[0017] As a preferred embodiment, the protective housing is further provided with a control panel, which includes a mode switching switch and a power switch for controlling the selection of the laser emitting component; It also includes a control circuit integrated in the control panel, which is electrically connected to the horizontal calibration module, the angle adjustment module and the laser emitting component respectively; the horizontal signal output by the horizontal calibration module is transmitted to the control circuit, and the control circuit drives the angle adjustment module to operate according to the signal until the laser emitting component reaches a horizontal state.

[0018] By adopting the above technical solution, the entire system is turned on by controlling the mode selection switch and the power switch. The horizontal calibration module first detects the horizontal state of the laser emitting component and transmits the detection signal to the control circuit. After receiving the horizontal signal, the control circuit analyzes it and sends a command to the angle adjustment module to adjust the angle of the laser emitting component until the laser emitting component reaches a completely horizontal state.

[0019] In summary, this application includes the following beneficial technical effects: 1. Compact structure and high stability: The horizontal calibration module is placed on the upper surface of the fixed base, and the laser emission module is placed on the vertical plane. The structure is reasonably laid out and has good overall rigidity. It can maintain higher stability in complex construction environments, thereby ensuring measurement accuracy.

[0020] 2.

[0021] 3. Integrated and Modular Design: The laser emission module integrates emission, adjustment, and protection functions into a single unit, facilitating installation, debugging, and maintenance. The control circuitry is integrated into the control panel, further optimizing the internal space layout.

[0022] 4. Wide applicability: With its dual fixing design of magnetic base and fixing holes, it can be quickly attached to metal surfaces and can also be firmly installed on various non-metallic surfaces such as concrete and wood with bolts, adapting to a variety of complex construction scenarios.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Please refer to the details. Figure 1 , Figure 2 and Figure 3 This application discloses a laser positioning and laying instrument that can be operated by a single person. It includes a fixed base 1, a fixed support 11 located at the middle of the lower end face of the fixed base 1, a horizontal calibration module 2 located at the middle of the upper end face of the fixed base 1, a support plate 6 connected to the vertical surface of the fixed base 1, and a laser emitting module located on the support plate 6.

[0027] Please refer to the details. Figure 1 , Figure 2 and Figure 3 The laser emitting module includes a protective housing 3 disposed on one side of the support plate 6, an angle adjustment module disposed between the protective housing 3 and the support plate 6, and a laser emitting component disposed on the protective housing 3.

[0028] Please refer to the details. Figure 1 , Figure 2 and Figure 3The horizontal calibration module 2 is used to detect the horizontal status of the mounting base 1 and output a horizontal signal, which is used to drive the protective housing 3 to rotate and adjust the projection angle of the laser emitting component. After the mounting base 1 is installed, the horizontal calibration module 2 detects its horizontal status and transmits the status information to the angle adjustment module through an electrical signal. The angle adjustment module drives the protective housing 3 to rotate according to the horizontal status information, adjusting the projection angle of the laser emitting component so that the laser is accurately aligned with the target position.

[0029] Please refer to the details. Figure 1 , Figure 2 and Figure 3 The angle adjustment module includes a support base 711 fixedly mounted on both sides of the support plate 6, a worm 71 rotatably connected to the support base 711, a worm wheel 72 meshing with the worm 71, a rotating shaft 721 connected to the worm wheel 72, and a drive motor 8 for driving the worm 71. The other end of the rotating shaft 721 passes through the support plate 6 and is connected to the protective housing 3. The rotating shaft 721 is fixedly connected to the protective housing 3. A sealed bearing is provided at the connection between the rotating shaft 721 and the support plate 6. The drive motor 8 is equipped with a stepper motor, and the output shaft of the drive motor 8 is connected to the worm gear 71.

[0030] The drive motor 8 drives the worm 71 to rotate via its output shaft. The worm wheel 72 meshes with the worm 71, allowing the rotation of the worm 71 to be transmitted to the worm wheel 72, which in turn drives the rotating shaft 721 to rotate. One end of the rotating shaft 721 is connected to the worm wheel 72, and the other end passes through the support plate 6 and is connected to and fixed to the protective housing 3, ensuring that the rotation of the protective housing 3 is synchronized with the rotation of the worm wheel 72. A sealed bearing is installed at the connection between the rotating shaft 721 and the support plate 6 to reduce friction during rotation and ensure sealing. The drive motor 8 is a stepper motor, with its output shaft directly connected to the worm 71. Precise control of the stepper motor's steps enables precise rotation of the worm 71. The entire device, through the precise control of the drive motor 8, causes the worm 71 to rotate, which in turn drives the worm wheel 72 to rotate. The rotation of the worm wheel 72 causes the rotating shaft 721 to rotate, ultimately driving the entire protective housing 3 to rotate, thereby achieving precise adjustment of the laser emission angle of the laser emitting component.

[0031] Please refer to the details. Figure 1 , Figure 2 and Figure 3The laser emitting assembly includes a horizontal laser diode 51 for emitting horizontal laser lines, a vertical laser diode 52 for emitting vertical laser lines, and a laser emission port 5 positioned relative to the horizontal and vertical laser diodes 51 and 52. The laser emission port 5 guides the laser lines emitted by the horizontal and vertical laser diodes 51 and 52. The horizontal and vertical laser diodes 51 and 52 are configured as red laser tubes with a wavelength of 650nm and a power of 5mW, producing clear beams that meet safety standards. The use of 650nm wavelength and 5mW red laser tubes for both the horizontal and vertical laser diodes 51 and 52 ensures clear beams and compliance with safety standards, making it suitable for various laser measurement and positioning applications. The laser emission port 5 plays a crucial role, guiding the laser lines emitted by the horizontal and vertical laser diodes 52 to ensure accurate target pointing. In principle, the laser lines emitted by the horizontal and vertical laser diodes 52, guided by the emission port, form aligned target lines, thereby achieving precise measurement and positioning.

[0032] Please refer to the details. Figure 1 , Figure 2 and Figure 3 The level calibration module 2 is an electronic bubble sensor, and this electronic bubble sensor is a digital tilt sensor. The digital tilt sensor can output the tilt angle of the device in the form of a digital signal, thereby achieving high-precision level calibration. In practical applications, this sensor can fix the tilt state of the base 1 in real time and transmit the data to the control circuit for processing.

[0033] Please refer to the details. Figure 3 The fixed support 11 is a magnetic base with a built-in permanent magnet, which enables the present invention to be adsorbed onto the metal surface.

[0034] Please refer to the details. Figure 2 and Figure 3 The protective housing 3 is also equipped with a control panel 4, which has a mode switching switch and a power switch for controlling the selection of the laser emission component.

[0035] It also includes a control circuit integrated into the control panel 4, which is electrically connected to the level calibration module 2, the angle adjustment module, and the laser emitting component. The level signal output by the level calibration module 2 is transmitted to the control circuit, which drives the angle adjustment module to operate according to the signal until the laser emitting component reaches a level state. The entire system is turned on by a mode selection switch and a power switch. The level calibration module 2 first detects the level state of the laser emitting component and transmits the detection signal to the control circuit. After receiving the level signal, the control circuit analyzes it and sends a command to the angle adjustment module to adjust the angle of the laser emitting component until the laser emitting component reaches a completely level state.

[0036] It also includes fixing holes 10 evenly distributed on both sides of the fixing base 1, so that the fixing base 1 can be securely installed on the non-metallic surface to be tested by bolt connection through the fixing holes 10.

[0037] The implementation principle of the laser positioning and laying-out instrument that can be operated by a single person in this application embodiment is as follows: First, the operator magnetically attaches the instrument to the metal surface via the fixed support 11. Alternatively, the fixing hole 10 can be used to securely mount the fixing seat 1 onto the non-metallic surface to be tested using bolt connections. The horizontal calibration module 2, located on the upper surface of the fixed base 1, monitors the horizontal status of the fixed base 1 in real time and transmits the detected horizontal signal to the control circuit. The control circuit compares the received horizontal signal with the built-in horizontal reference value. If a horizontal deviation exists, the control circuit generates a corresponding control command to drive the drive motor 8 in the angle adjustment module.

[0038] The drive motor 8 drives the worm gear 71 to rotate, which in turn drives the meshing worm wheel 72 to rotate, thereby causing the rotating shaft 721, which is fixedly connected to the worm wheel 72, to rotate. Since the rotating shaft 721 is fixedly connected to the protective housing 3, the protective housing 3, along with the laser emitting component inside it, will deflect. This adjustment process continues, forming a closed-loop feedback system, until the level calibration module 2 detects that the fixed base 1 has reached a horizontal state. At this point, the control circuit stops driving the stepper motor, and the laser emitting component is in a precise horizontal reference position.

[0039] Finally, the operator selects the desired horizontal, vertical, or crosshair mode using the mode switch on control panel 4. The corresponding horizontal laser diode 51 or vertical laser diode 52 in the laser emitting assembly is activated, and the emitted laser is projected out through laser emission port 5, forming a clear baseline on the work surface for the operator to perform single-person line laying operations.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
