Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, specifically a laser monitoring device for tunnel curvature. Background Technology

[0002] A tunnel is a man-made underground passage, typically used to cross mountains, rivers, roads, or other obstacles to connect two points. It generally consists of an excavated or drilled tunnel body and entrances at both ends, with sufficient internal space to accommodate people and vehicles. Tunnel construction requires precise geological surveys, structural design, construction techniques, and safety management to ensure its stability and safety. In modern transportation systems, tunnels play a vital role, shortening travel distances and improving traffic efficiency. They are also an important component of urban planning and development. During tunnel construction, various testing equipment is needed to inspect the tunnel's interior.

[0003] For example, authorization announcement number CN218496042U discloses a monitoring device for large deformation of weak surrounding rock in tunnels, belonging to the field of tunnel surrounding rock monitoring technology. This monitoring device for large deformation of weak surrounding rock in tunnels includes a base and monitoring components. The base includes a vehicle body and a crash bar. The monitoring components include a fixed rod, a telescopic rod, and a laser scanner. The fixed rod has a through groove on its surface, and a positioning rod is rotatably mounted inside the through groove. A motor is mounted outside the fixed rod, and the motor is connected to the positioning rod. The laser scanner rotates on the fixed rod via the telescopic rod. The laser scanner is positioned at the top of the telescopic rod, and the drive motor facilitates the rotation of the telescopic rod inside the through groove, thereby adjusting the position of the laser scanner. Driving the telescopic rod improves the scanning fit between the laser scanner and the scanning area, thus enhancing the monitoring effect.

[0004] Detecting tunnel curvature requires the use of laser detection equipment. The aforementioned technology mounts the detection equipment on a movable vehicle, which is convenient for movement, but the unevenness of the tunnel surface makes it difficult to adjust the level of the detection equipment, thus affecting the accuracy of the measurement. Therefore, there is an urgent need in the market to develop a laser monitoring device for tunnel curvature to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tunnel curvature laser monitoring device to solve the problem mentioned in the background art that the detection device is installed on a movable vehicle, which is convenient for movement, but the uneven tunnel ground makes it difficult to adjust the level of the detection device, thus affecting the accuracy of the measurement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel curvature laser monitoring device, comprising a base plate, with supporting circular plates provided at both the front and rear ends of the lower end face of the base plate, electrically controlled telescopic rods fixedly provided at both the front and rear ends of both sides of the upper end face of the base plate, a support rod fixedly connected to one side of the middle of the upper end face of the base plate, a rotating seat fixedly connected to the upper end of the support rod, a level rotatably connected to the upper end of the rotating seat, a support column fixedly connected to the middle of the upper end face of the base plate, a transmission seat fixedly connected to the upper end of the support column, a mounting plate rotatably connected to the upper end of the transmission seat, and a laser detection device fixedly provided at the upper end of the mounting plate.

[0007] Preferably, the lower ends of the telescopic ends of the four electrically controlled telescopic rods extend out of the lower end face of the base plate and are fixedly connected to the upper end face of the four supporting circular plates respectively, and the lower end face of the four supporting circular plates is fixedly connected with a chisel.

[0008] Preferably, the lower middle part of the level is rotatably connected to the upper end of the rotating seat via a rotating shaft.

[0009] Preferably, a circular opening is provided in the middle of the upper end face of the transmission seat, and a rotating column is fixedly connected to the middle of the lower end of the mounting plate.

[0012] Preferably, the worm gear is meshed with the teeth of the worm wheel on the rotating column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the horizontal state of the tunnel curvature laser monitoring equipment is calibrated and adjusted by the combination of the level and the electric telescopic rod. This design can ensure that the laser detection equipment always maintains a horizontal state during the measurement process, thereby effectively improving the accuracy and reliability of the measurement results. At the same time, the precise adjustment function of the electric telescopic rod also greatly simplifies the tedious process of manually adjusting the horizontal state and improves work efficiency.

[0015] (2) In this utility model, the combination of the support plate and the drill rod provides stable and reliable support for the equipment. The design of the support plate increases the contact area between the equipment and the ground, improving the stability of the equipment. The drill rod can be deeply inserted into the ground to provide additional fixing force for the equipment, effectively preventing the equipment from shifting due to uneven tunnel ground or construction vibration.

[0016] (3) In this utility model, the direction of the laser detection equipment can be flexibly adjusted by setting the transmission seat. The worm gear transmission mechanism integrated inside the transmission seat can stably and accurately drive the laser detection equipment to rotate in the horizontal plane, easily meeting the needs of monitoring the curvature of different sections of the tunnel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a tunnel curvature laser monitoring device, comprising a base plate 1. Supporting circular plates 102 are provided at both the front and rear ends of the lower surface of the base plate 1. Electrically controlled telescopic rods 101 are fixedly provided at both the front and rear ends of the upper surface of the base plate 1. The lower ends of the telescopic ends of the four electrically controlled telescopic rods 101 extend beyond the lower surface of the base plate 1 and are respectively fixedly connected to the upper surfaces of the four supporting circular plates 102. After the base plate 1 is moved to a suitable position in the tunnel, it is supported by the supporting circular plates 102. A drill rod 103 is fixedly connected to the lower surface of each of the four supporting circular plates 102, and the drill rods 103 are inserted into the ground to prevent the base plate 1 from moving. A support rod 2 is fixedly connected to one side of the middle of the upper surface of the base plate 1. A rotating seat 201 is fixedly connected to the upper end of the support rod 2, and a water-cooled... The level 202 has a support column 3 fixedly connected to the middle of the upper surface of the base plate 1. The upper end of the support column 3 is fixedly connected to the transmission seat 301. The upper end of the transmission seat 301 is rotatably connected to the mounting plate 4. The upper end of the mounting plate 4 is fixedly equipped with a laser detection device 5. By observing whether the bubble in the level 202 is in the center position, the operator can know whether the laser detection device 5 is level. The lower middle of the level 202 is rotatably connected to the upper end of the rotating seat 201 through a rotating shaft 203. By rotating the level 202, the operator can detect whether the base plate 1 is level in different directions. When the base plate 1 is detected to be level, the operator can adjust the extension of the electrically controlled telescopic rod 101 in the tilt direction to raise the tilted side of the base plate 1, thereby adjusting the base plate 1 to be level and ensuring that the laser detection device 5 is in a level state, thus improving the measurement accuracy of the laser detection device 5.

[0024] Please see Figure 2-4 A circular opening 302 is provided in the middle of the upper end face of the transmission base 301. A rotating column 401 is fixedly connected to the middle of the lower end of the mounting plate 4. The lower end of the rotating column 401 is inserted into the transmission base 301 along the circular opening 302. A worm gear 402 is fixedly connected to the lower end of the outer end face of the rotating column 401 and inside the transmission base 301. A servo motor 303 is fixedly installed at the rear end of one side inside the transmission base 301. A worm 304 is fixedly connected to the front output end of the servo motor 303. The worm 304 meshes with the worm gear 402 on the rotating column 401. The servo motor 303 drives the worm 304 to rotate, which in turn drives the rotating column 401 to rotate, so that the mounting plate 4 drives the laser detection equipment 5 to adjust its direction.

[0025] Working Principle: During use, the operator moves the base plate 1 to the predetermined position inside the tunnel where curvature monitoring is required. At this time, the four supporting circular plates 102 at the lower end of the base plate 1 are in contact with the ground, and the drill rods 103 at the lower end of each supporting circular plate 102 are deeply inserted into the ground, providing stable support for the entire device and effectively preventing equipment displacement caused by uneven tunnel ground or construction vibrations. Next, the operator observes the level 202. The level 202 is connected to the rotating base 201 via the rotating shaft 203, allowing for flexible adjustment of the observation angle to comprehensively check whether the base plate 1 and the laser detection equipment 5 installed above it are level. If the level 202 indicates that the equipment is not level, the operator will, as needed, precisely adjust the height of the base plate 1 using the telescopic adjustment function of the electrically controlled telescopic rod 101 until the level 202 indicates that the equipment is completely level. This step ensures that the laser detection equipment 5 remains level throughout the measurement process, thereby improving the accuracy of the measurement results. Subsequently, the operator starts the servo motor 303. The servo motor 303 is located inside the transmission base 301, and its front end outputs a worm gear 304 that meshes tightly with the worm wheel teeth 402 on the rotating column 401 at the lower end of the mounting plate 4. When the servo motor 303 rotates, the worm gear 304 drives the worm wheel teeth 402 and the rotating column 401 to rotate together, thereby driving the mounting plate 4 and the laser detection device 5 fixed on it to rotate horizontally within the circular opening 302 provided by the transmission base 301. This rotation mechanism allows the laser detection device 5 to flexibly adjust the scanning direction, achieving comprehensive monitoring of the curvature of different sections of the tunnel.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
