[0023] The present utility model will be further described below in conjunction with the specific embodiments. Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to this patent; in order to better illustrate the embodiments of the present utility model, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0024] like Figures 1-3 As shown, the utility model mentions an intelligent tunnel over-excavation and under-excavation detection device, comprising a scanner 1, an ultrasonic detector 2, a central processing unit 4 and a mobile carrier 6, wherein the scanner 1 can rotate 360°, can transmit the real-time image obtained by scanning to the central processing unit, is responsible for observing the surrounding conditions of the tunnel, and assists the movement of the device; the ultrasonic detector 2 is mainly an ultrasonic rangefinder, which is responsible for detecting the tunnel face and generating corresponding images, that is, it can emit ultrasonic waves to the surroundings, and use the reflected sound waves as a signal source for calculation to detect the over-excavation and under-excavation of the tunnel; the mobile carrier 6 is composed of a platform 61, a guide rail 62, a moving magnet 63, a telescopic support leg 65, and a wheel 66. The scanner 1, the ultrasonic detector 2 and the central processing unit 4 are installed on the upper part of the platform 61, and the lower part of the platform 61 is provided with two guide rails 62 extending in its width direction and arranged in parallel in the length direction, and a single guide rail 62 is provided along its extension direction. Two movable magnets 63 are arranged to be slidably connected thereto, that is, the movable magnets 63 are located inside the guide rail 62 and are surrounded by it. Both of them have variable magnetism, and the entire device is supported by magnetism. The movable magnets 63 can move freely in the guide rail 62 by magnetism to achieve the effect of changing the distance between the axes. A single movable magnet 63 is connected to a telescopic leg 65 that can telescopically change the overall height of the movable carrier 6 at the end away from the guide rail 62. A wheel 66 is arranged at the bottom of the telescopic leg 65. The central processor 4 includes an illumination scanning module 41 electrically connected to the scanner 1, an over-excavation detection module 42 electrically connected to the ultrasonic detector 2, and a movement control module 43 electrically connected to the movable magnet 63. The side walls of the platform 61 are surrounded by illumination lines 5 electrically connected to the illumination scanning module 41. The illumination lines 5 are used to illuminate the surrounding environment of the device, so as to cooperate with the scanner 1 to observe the internal conditions of the tunnel. The use of magnetic suspension technology makes the device move more smoothly, and the height of the axle and the distance between the axles can be changed within a certain range, and the adaptability is stronger.
[0025] In this embodiment, the mobile carrier 6 further includes a protective slider 64 for preventing the moving magnet 63 from directly contacting the guide rail 62. A protective slider 64 is provided on a single guide rail 62 and along its extension direction and on both sides of the moving magnet 63. The addition of the protective slider can improve the stability and reliability of the device, protect the guide rail and the moving magnet, and also reduce the cost of maintenance and servicing.
[0026] In this embodiment, a clearing shovel 7 is provided on the telescopic legs 65 and in front of the wheels 66 on the telescopic legs 65 for clearing some obstacles and protecting the wheels 11 when the mobile carrier 6 moves. The clearing shovel can be used to clear obstacles or debris that may exist in the tunnel, ensuring that the mobile carrier is not hindered during movement and ensuring the smooth operation of the device.
[0027] In this embodiment, a rotating roller 67 for adjusting the direction of the wheel 11 and controlling the overall moving direction of the mobile carrier 6 is provided between the telescopic support leg 65 and the wheel 66. The rotating roller 67 is also electrically connected to the movement control module 43. The addition of the rotating roller enables the mobile carrier to rotate and move more flexibly, reduces friction, and improves the smoothness and stability of movement. And by being electrically connected to the movement control module, precise control of the rotating roller can be achieved, making the device more precise and controllable during movement and enhancing its performance in practical applications. The telescopic support leg 65 is an electric telescopic rod, and the telescopic support leg 65 is also electrically connected to the movement control module 43. Through the electric telescopic rod, rapid and precise control of the length of the telescopic support leg can be achieved, improving the stability and adjustability of the device. At the same time, by electrically connecting the telescopic support leg to the movement control module, remote control of the telescopic support leg can be realized, facilitating the operator to adjust and control the height of the device and improving the convenience and flexibility of operation.
[0028] In this embodiment, a power supply 3 for supplying power to the scanner 1, ultrasonic detector 2, central processor 4, lighting wire 5, moving magnet 63, telescopic support leg 65, and rotating roller 67 is further provided on the platform 61. Such a design can ensure the stability and continuous working ability of the device. At the same time, by setting the power supply on the platform, it is also convenient for the power supply management and maintenance of each component of the device, making the operation more convenient and efficient.
[0029] The working principle of the present utility model is described below: The staff controls the device to enter the tunnel through the operation terminal. The surrounding environment of the tunnel is illuminated by the lighting wire 5. The scanner 1 transmits the scanned image to the central processor 4 and feeds it back to the operation terminal. The staff controls the advancing direction of the mobile carrier 6 by controlling the rotating roller 67 according to the observed image. When encountering a small obstacle, the obstacle clearing shovel 7 can clear the obstacle while moving forward without affecting the progress; when encountering an obstacle that the obstacle clearing shovel 7 cannot handle, it can only move around the obstacle. The staff can remotely adjust the telescopic support leg 65 to change the overall height of the mobile carrier 6, or control the moving magnet 63 to change the axial distance, so as to achieve the purpose of bypassing the obstacle. After the device reaches the designated destination, the ultrasonic detector 2 starts to work, emits ultrasonic waves into the tunnel, and the central processor 4 calculates using the reflected sound wave as the signal source to detect the overbreak and underbreak conditions of the tunnel. In this way, the operation of the tunnel intelligent overbreak and underbreak detection device is realized, which can adapt to tunnel construction with various complex obstacles. While ensuring the measurement accuracy of the tunnel overbreak and underbreak, it can minimize human and material resources to the greatest extent, reduce operating costs, and improve economic benefits. Generally speaking, the tunnel intelligent overbreak and underbreak detection device of the present utility model has the advantages of improving work efficiency, safety, and adaptability, and has important practical value for the tunnel construction process.
