[0032] The present disclosure provides a laser indicating device, including a support base and a control box. The control box is mounted on the support base, and a laser rangefinder and a laser emitting device are provided on the control box. The laser rangefinder is configured to measure the distance between the laser indicating device and the side wall of the roadway, and the laser emitting device is configured to emit laser light. The laser emitting device includes indicating lights, which are configured to be arranged in a matrix on the xy plane. The spacing between the indicating lights is a first distance, and the row spacing is a second distance. Taking the central column as a reference, the remaining columns have a first angle with the yz plane. Taking the bottom row as a reference, the remaining rows have a second angle with the xz plane.

[0033] The laser indicating device provided by the present disclosure can improve the efficiency and accuracy of drilling marking, reduce environmental pollution, and ensure the safety of the staff.

[0034] For the sake of easy understanding, hereinafter, with reference to Figures 1 to 4 , the specific structure and working principle of the laser indicating device of the present disclosure will be described in detail in conjunction with an embodiment.

[0035] As shown in Figure 1 , Figure 3 and Figure 4 , the laser indicating device provided by the present disclosure includes a support base 1 and a control box 2. The control box 2 is mounted on the support base 1, and a laser rangefinder 3 and a laser emitting device 4 are provided on the control box 2. The laser rangefinder 3 is configured to measure the distance between the laser indicating device and the side wall of the roadway, and the laser emitting device 4 is configured to emit laser light. The laser emitting device 4 includes indicating lights 5, which are configured to be arranged in a matrix on the xy plane. The spacing between the indicating lights 5 is a first distance, and the row spacing is a second distance. Taking the central column as a reference, the remaining columns have a first angle with the yz plane. Taking the bottom row as a reference, the remaining rows have a second angle with the xz plane. The xy plane is the plane determined by the x-axis and the y-axis, the yz plane is the plane determined by the y-axis and the z-axis, the xz plane is the plane determined by the x-axis and the z-axis, and the y-axis is the axis extending in the height direction.

[0036] Specifically, the support base 1, as the basic part of the entire laser indicating device, is used to stably place and fix other components. A control box 2 is installed on the top of the support base 1. The control box 2 integrates an electronic control system, which can adjust the direction and distance of laser emission. A laser rangefinder 3 and a laser emitting device 4 are also arranged on the control box 2. The laser rangefinder 3 is used to measure the actual distance between the laser indicating device and the side wall of the roadway, which can ensure that the laser emitted by the laser emitting device 4 can be projected to a predetermined position. The laser emitting device 4 includes indicating lights 5 arranged in a matrix. The indicating lights 5 are located on the xy plane. The spacing between the indicating lights 5 (i.e., the distance in the horizontal direction) is the first distance, and the row spacing (i.e., the distance in the vertical direction) is the second distance. Taking the center column of the indicating lights 5 as a reference, each of the remaining columns except the center column forms a first angle with the yz plane, so as to ensure that the laser beam has a certain inclination in the height direction. Taking the bottom row of the indicating lights 5 as a reference, each of the remaining rows except the bottom row forms a second angle with the xz plane, so that the laser beam has a certain inclination in the horizontal direction.

[0037] In this embodiment, the xy plane is the plane determined by the x-axis and the y-axis, the yz plane is the plane determined by the y-axis and the z-axis, and the xz plane is the plane determined by the x-axis and the z-axis. The y-axis is the axis extending in the height direction, that is, the vertical direction. By setting the row spacing and spacing between the indicating lights 5, and controlling the first angle and the second angle, the laser indicating device can accurately display the predetermined position of the anchor bolt on the side wall of the roadway, thus simplifying the process of manual line laying, reducing material waste, improving the standardization effect, and at the same time reducing the safety risk of workers working at heights.

[0038] The working process of the laser indicating device in this embodiment is as follows:

[0039] First, when the laser indicating device is activated, the electronic control system starts to work. It first measures the actual distance between the laser indicating device and the sidewall of the roadway through the laser rangefinder 3. After that, based on the set spacing and row spacing, and the actual distance between the laser indicating device and the sidewall of the roadway feedback by the laser rangefinder 3, the electronic control system calculates the angles between each indicator light 5 and the yz plane and the xz plane, so as to generate the angular coordinates of each indicator light 5. Each indicator light 5 is provided with an angle adjustment device, and the electronic control system adjusts the angles between each indicator light 5 and the yz plane and the xz plane through the generated angular coordinates. Next, the indicator lights 5 in the laser emitting device 4 are activated and emit laser beams, which can project the laser beams to the predetermined positions efficiently and accurately, realizing the effective indication of the roadway or other working environments. In this embodiment, the height of the bottom row of indicator lights 5 from the floor in the laser indicating device should be consistent with the height of the bottom row of drill holes in the roadway rib. And the laser indicating device controls 15 drill hole positions (3×5) at a time. After the drilling construction of the previous cycle is completed, move the laser indicating device forward along the device migration strip (front move within a 0.5m-wide strip, that is, the z value change range is ±0.25, which can reduce the angle adjustment range of the indicator lights), and adjust the laser indicating device in the above order. To ensure that the drill holes in the front and back cycles are in rows, after aligning the last column of laser indicator lights on the roadway rib in the next cycle with the first column of bolts in the previous cycle, carry out the drilling construction of the next cycle.

[0040] The following illustrates the specific calculation process of the indicator light coordinates in this embodiment by way of example:

[0041] For example, the electronic control system calculates the angles between each numbered indicator light 5 and the yz plane and the xz plane based on the set spacing a, row spacing b of the indicator lights and the distance z between the laser indicating device and the surface of the roadway rib feedback by the system, generates the angular coordinates (φ, θ) of each indicator light 5, and the control system realizes the automatic control of drill hole positioning through the indicator light angle adjustment device. The angular coordinates (φ, θ) of each numbered indicator light are shown in Table 1.

[0042] Table 1

[0043]

[0044] In an embodiment of the present disclosure, the indicator lights 5 are arranged in three rows and five columns, and both the first angle and the second angle are from 0° to 90°.

[0045] Specifically, as Figure 3As shown, 15 indicator lights 5 can be set, and the indicator lights 5 are arranged in a matrix in a three-row and five-column manner. Taking the central column as a reference, the inclination angles formed by the remaining columns and the yz plane are any angles between 0° and 90°. This can ensure that the laser beam has a certain inclination in the height direction, and in most cases, the inclination angles of each column of indicator lights 5 are the same. Similarly, taking the bottom row of indicator lights 5 as a reference, the inclination angles formed by the remaining rows and the xz plane are also any angles between 0° and 90°. This can make the laser beam have a certain inclination in the horizontal direction, and in most cases, the inclination angles of each row of indicator lights 5 are the same.

[0046] When the laser indicating device is turned on, the laser rangefinder 3 will automatically measure the distance from the sidewall of the roadway and adjust the angle of the laser emitting device 4 to ensure that the laser beam can be projected onto the sidewall at a preset angle and distance. The laser emitted by the indicator light 5 will form a series of light spots on the sidewall, and these light spots represent the predetermined positions of the anchor bolts. By adjusting the first angle and the second angle, laser beams with different inclinations can be projected to adapt to different construction requirements, thereby improving the accuracy and efficiency of anchor bolt positioning, reducing manual operation errors and workload, and at the same time reducing safety risks during construction. It can not only ensure that the anchor bolts are constructed according to the designed spacing, but also improve the overall construction quality and safety.

[0047] In an embodiment of the present disclosure, the support base 1 includes a first support rod 6 extending in the vertical direction and a second support rod 7 extending in the horizontal direction.

[0048] Specifically, as Figure 1As shown, the support seat 1 includes at least a first support rod 6 and a second support rod 7, wherein the first support rod 6 extends in the vertical direction and mainly assumes the role of providing support in the vertical direction to ensure that the entire device can remain stable in the vertical direction; and the second support rod 7 extends in the horizontal direction to provide support in the horizontal direction, which helps to enhance the device's ability to resist external disturbances and ensure the stability of the device in the horizontal direction. In order to further increase the stability and reliability of the mechanical structure, the design of the support seat 1 can also include reinforcing ribs and crossbeams to improve the rigidity and bending resistance of the overall structure. In addition, an adjustable foot pad is installed at the bottom of the support seat 1, which can be adjusted according to the unevenness of the ground to ensure that the support seat 1 can remain horizontal under any terrain conditions, thereby improving the accuracy of the laser pointing device. In order to further improve the stability of the support seat 1, a locking device is set on the support rod, and the position of the support rod is fixed by a knob or other locking mechanism to ensure the stability of the device during the entire working process. The bottom of the support seat 1 is made of anti-slip material or designed as a serrated surface to increase the friction between the ground and further improve the stability of the support seat 1, which is more important when working on slippery or unstable ground. The support base 1 in this embodiment can not only provide a more stable foundation for the laser pointing device, but also ensure the reliability and durability under various working conditions, and provide solid support for the normal operation of the laser pointing device.

[0049] In one embodiment of the present disclosure, the first support rod 6 is a telescopic structure, and the first support rod 6 is configured to adjust the height of the support seat 1 .

[0050] Specifically, the first support rod 6 extending in the vertical direction adopts a retractable structure, and the height of the support seat 1 can be adjusted to adapt to different working environments and needs. This retractable structure can adjust the height of the support seat 1 according to different construction conditions and needs, which helps to ensure that the laser pointing device can work stably under various height conditions and can better adapt to the changes in the internal space of the tunnel. In order to further increase the flexibility and practicality of the mechanical structure, a multi-stage telescopic section can be set on the first support rod 6, and each stage of the telescopic section can be fixed by a threaded connection or a quick lock mechanism so as to quickly adjust to the required length; at the same time, in order to ensure stability during the telescopic process, a guide track or guide groove can be set inside the first support rod 6 to reduce shaking during telescopic operation. In addition, in order to improve the carrying capacity and stability of the first support rod 6, a reinforcement ring or a transverse support member can be installed at its bottom to increase the overall rigidity of the first support rod 6. In order to facilitate the operator to control the telescopic process, a handle or handle that is easy to hold can also be set on the first support rod 6, so that the height adjustment becomes easier and more convenient, and the flexibility and convenience of the first support rod 6 are improved.

[0051] In an embodiment of the present disclosure, a moving device 8 is provided at the bottom of the support base 1. The moving device 8 is installed at the bottom or side of the second support rod 7 and is configured to control the movement of the support base 1.

[0052] Specifically, as Figure 1 shown, the moving device 8 is installed at the bottom or side of the second support rod 7 and can be a pulley, a slide rail or other moving mechanisms. Its main function is to control the movement of the support base 1 so that the entire laser indicating device can move flexibly in the roadway. In this embodiment, it is preferably to use a pulley as the moving device 8 because the pulley has a simple structure and convenient operation, which helps to improve the construction efficiency and reduce the time and labor intensity of repeated setting. To further increase the stability and practicality of the entire device, a braking system can be installed on the pulley to quickly fix the position when needed. At the same time, the pulley can be selected with a shock-absorbing function design to reduce the vibration generated when moving on uneven ground and improve the stability of the laser indicating device during operation. In addition, a telescopic auxiliary leg can be provided on the side of the second support rod 7 to provide additional support in specific situations and ensure the stability of the device in the moving or fixed state. To facilitate the operator to control the moving device 8, auxiliary devices such as a handle or a push rod can also be provided on the second support rod 7 to facilitate manual control of the moving device 8, ensure that the laser indicating device can move smoothly and accurately to the required position, not only improve the flexibility and convenience of the moving device 8, but also enhance the adaptability and working efficiency of the laser indicating device in different working environments.

[0053] In an embodiment of the present disclosure, a universal adjustment device 9 is provided at the connection between the support base 1 and the control box 2. The universal adjustment device 9 is configured to adjust the direction of the control box 2.

[0054] Specifically, as Figure 1As shown, the universal adjustment device 9 is installed at the connection between the support base 1 and the control box 2, and is used to adjust the direction of the control box 2 to ensure that the laser emission device 4 can be adjusted omnidirectionally as needed. The universal adjustment device 9 allows the control box 2 to rotate and tilt in multiple directions to adapt to different angular requirements, so as to ensure that the laser beam can be accurately projected to the predetermined position, whether in the horizontal direction or the vertical direction.

The power supply box 10 is internally equipped with a power supply system, which provides stable power support for the laser rangefinder 3, the laser emission device 4 and other electronic devices in the control box 2, ensuring that the device can operate continuously for a long time. The design of the power supply box 10 takes into account the safe power supply problem in complex environments, and can effectively avoid electrical faults such as overload and short circuit, ensuring the safe operation of the device. In order to further increase the stability and safety of the mechanical structure, the power supply box 10 adopts a sturdy shell design, which can effectively protect the internal power supply system from external impacts and harsh environments. A heat dissipation device, such as a fan or a heat sink, is also provided inside the power supply box 10 to ensure that the power supply system will not degrade in performance due to overheating during long-term operation. In addition, the power supply box 10 is equipped with an overload protection circuit and a short circuit protection circuit, which can automatically cut off the power supply when abnormal current is detected, preventing the occurrence of electrical faults.

[0058] Specifically, as Figures 1 to 2 shown, the spirit level 11 and the compass 12 are arranged on the top of the control box 2 to monitor the state of the laser indicating device. The spirit level 11 is used to monitor the tilt angle of the laser indicating device and to adjust the tilt angle of the laser indicating device to be consistent with the inclination angle of the roadway in the construction section. The compass 12 is used to monitor the position of the laser indicating device, which can help the operator determine the position of the device relative to the roadway direction and ensure that the azimuth of the laser indicating device is consistent with the roadway driving azimuth. In order to further increase the functionality and practicality of the device, the spirit level 11 can adopt a high-precision electronic spirit level 11 equipped with a digital display screen to facilitate the operator to intuitively read the tilt angle of the device; the compass 12 can integrate magnetic compass or electronic compass technology to provide accurate direction information to help the operator accurately adjust the position of the device. In order to improve the stability and durability of these instruments, a protective cover can be provided around the spirit level 11 and the compass 12 to prevent dust and moisture from invading.

[0059] In an embodiment of the present disclosure, the laser indicating device further includes an obstacle sensor disposed on the support base 1 and configured to monitor obstacles.

[0060] Specifically, the obstacle sensor is disposed on the support base 1 for monitoring surrounding obstacles to ensure that the device can avoid obstacles during movement, thereby improving safety. The obstacle sensor helps the operator timely adjust the movement path and avoid collisions by detecting whether there are obstacles around the device, such as rocks, equipment, or other obstacles, thus enhancing the safety and efficiency of the operation. The obstacle sensor can adopt an ultrasonic sensor or an infrared sensor. These sensors have good penetration and non-contact characteristics and can accurately detect the distance of obstacles under different light conditions. To improve the response speed and accuracy of the sensor, multiple sensors can be set at different positions on the support base 1 to form an all-round detection network to ensure that obstacles can be detected in a timely manner from all directions. Additionally, a waterproof and dustproof housing can be equipped for the sensor to protect it from external factors. Moreover, to facilitate the operator to receive the sensor signal and make a response, an alarm system, such as a sound alarm or a light prompt, can be integrated on the control box 2 to immediately remind the operator to take measures once an obstacle is detected.

[0061] In an embodiment of the present disclosure, the laser indicating device further includes a light sensor installed inside the control box 2 and configured to monitor the light intensity in the roadway.

[0062] Specifically, the light sensor is installed inside the control box 2 for monitoring the light intensity in the roadway. By monitoring the light intensity in the roadway, it helps the operator understand the light conditions of the working environment and ensures the visibility and accuracy of the laser beam under different light conditions. If the light is dim, the operator can take measures to enhance the brightness of the laser beam or adjust the parameters of the laser beam to ensure the accuracy of bolt positioning. The light sensor can adopt a high-sensitivity photoelectric sensor that can accurately measure the ambient light intensity and transmit the data to the electronic control system inside the control box 2. In addition, an automatic adjustment function can be integrated inside the control box 2 to automatically adjust the power of the laser emitting device 4 according to the light intensity data feedback by the light sensor to ensure the visibility and accuracy of the laser beam under different light conditions. To facilitate the operator to monitor the light intensity, the real-time light intensity value can be displayed on the display screen of the control box 2, or corresponding indicator lights can be set so that the operator can intuitively understand the current light condition.
