Description

Technical Field

[0001] This application relates to the field of tunnel detection technology, and in particular to a tunnel detection device. Background Technology

[0002] Currently, tunnel construction is a high-risk operation deep underground in harsh environments. The ventilation system is the "breathing system" and "lifeline" of the entire project. During tunnel excavation, some rock masses contain radioactive gases. When these gases leak, they accumulate near the tunnel face, posing a threat to construction workers. Therefore, the tunnel ventilation system plays a crucial role in tunnel construction. It dilutes the radioactive gases within the tunnel and supplies fresh air. Before treating radioactive gases, the ventilation system typically needs to detect and identify their locations and treat these areas accordingly to reduce the probability of leakage.

[0003] Related technology can be found in Chinese patent application CN115949865B, which discloses a tunnel detection device. This device includes a walking device, a track bed detection device, an operating platform, a steering gimbal, and an arch detection device. The walking device is movably connected to a track and can move along it. The track bed detection device is mounted on the walking device and includes a first detection element facing the track bed. The operating platform is mounted on the walking device and can move along the track with it, positioned above the walking device. The steering gimbal is mounted on the operating platform. The arch detection device includes a second detection element mounted on the steering gimbal, which moves relative to the operating platform with the steering gimbal and faces the tunnel arch. This device can simultaneously detect defects at multiple locations within the tunnel, improving the efficiency of tunnel defect detection and shortening the detection cycle.

[0004] Regarding the aforementioned technologies, the tunnel detection equipment can only detect the tunnel's arch and track bed when detecting tunnels. However, during the safe operation of the tunnel, safety hazards can also occur at the arch waist and arch feet. The arch feet, arch waist, and arch are connected as a whole structure and share the load. Therefore, during the tunnel detection process, it is necessary to detect the arch feet, arch waist, and arch simultaneously to increase the detection range of the tunnel. Summary of the Invention

[0005] To improve the range of tunnel detection, this application provides a tunnel detection device.

[0006] This application provides a tunnel detection device, which adopts the following technical solution: A tunnel detection device includes a drive unit, a support unit, and a detection component. The drive unit is connected to the lower end of the support unit, and the detection component is connected to the support unit. The support unit supports the detection component, which is used to detect the tunnel. The detection component includes an arch foot detector, an arch waist detector, and an arch top detector. The arch foot detector is located on one side of the support unit along its width direction and is used to detect the arch foot of the tunnel. The arch waist detector is located on the upper end of the support unit near the arch foot detector and is used to detect the arch waist of the tunnel. The arch top detector is located on the upper end of the support unit away from the arch waist detector and is used to detect the arch top of the tunnel.

[0007] By adopting the above technical solution, when it is necessary to detect the surrounding rock of the tunnel, the support component supports the detection component, the driving component moves the detection component to the position to be detected, the arch foot detection component detects the arch foot of the tunnel, the arch waist detection component detects the arch waist of the tunnel, and the arch top detection component detects the arch top of the tunnel. During the detection process, the distance between the arch foot detection component, the arch waist detection component, and the arch top detection component and the tunnel remains consistent, thereby detecting the entire cross section of the tunnel at the same time and improving the detection range of the tunnel.

[0008] Optionally, the driving component includes a base, four driving wheels, and four driving motors. The upper end of the base has a vertically oriented placement groove, and the lower end of the support is located in the placement groove. The four driving wheels are located on both sides of the base along the width direction, and the two driving wheels on the same side are located on both sides of the base along the length direction. The driving wheels are rotatably connected to the base. The driving motors correspond one-to-one with the driving wheels. The driving motors are located inside the placement groove and are fixedly connected to the base. The driving motors are arranged along the width direction of the base, and the output shaft of the driving motor passes through the base and is coaxially fixedly connected to the driving wheels.

[0009] By adopting the above technical solution, the support component is located in the placement slot, which helps to reduce the probability of the support component shaking during movement. The base supports the support component, and the drive motor drives the drive wheel to rotate, thereby moving the detection component to the designated position, which improves the convenience of moving the detection component.

[0010] Optionally, the support components include a support block, four rectangular blocks, four rectangular tubes, and four spring dampers. Each rectangular tube corresponds to a drive motor. The four rectangular tubes are vertically positioned and located inside the placement slot. The four rectangular tubes are located on both sides of the base along the width direction and on the side where the two drive motors are close to each other. The rectangular tubes are fixedly connected to the base. Each rectangular block corresponds to a rectangular tube.

When encountering bumpy road sections, the rectangular block slides inside the rectangular tube, and the spring damper buffers the rectangular block and the support block, so that the detection component remains stable during movement, thereby improving the stability of the detection component during the detection process.

[0012] Optionally, the arch foot detection component includes a first motor, a gear, a rack, a rotating block, a first telescopic component, and a first detector.

The gear is located above the rotating block and meshes with the rack. The first telescopic component is located outside the support block and is connected to the rotating block. The first detector is connected to the end of the first telescopic component away from the support block.

[0013] By adopting the above technical solution, when the location of the tunnel arch foot is detected, the first motor causes the gear to rotate on the surface of the rack. The gear and rack work together to drive the rotating block to rotate in the rotating opening. The rotation of the rotating block drives the first telescopic component and the first detector to rotate. During the rotation of the first detector, the first telescopic component extends, so that the distance between the first detector and the tunnel arch foot remains consistent, thereby improving the detection range of the arch foot detector.

The second detector is fixedly connected to the upper end of the second support rod.

[0017] By adopting the above technical solution, the distance from the upper end of the first positioning block to the upper end and the lower end of the arch waist is the same. The first positioning block supports the second motor, the second motor drives the second support rod to rotate, and the second support rod drives the second detector to rotate, thereby completing the detection of the tunnel arch waist and improving the convenience of tunnel arch waist detection.

[0018] Optionally, the arch detection component includes a second positioning block, a third motor, a second telescopic component, and a third detector.

[0019] By adopting the above technical solution, the second positioning block supports the third motor, and the third motor and the second telescopic component work together to enable the third detector to detect the tunnel arch, and keep the distance between the third detector and the tunnel arch consistent during the detection process, thereby improving the convenience of tunnel arch detection.

[0020] Optionally, the second telescopic component includes a third support rod, a second sliding rod, a third positioning block, a first rotating rod, and a second rotating rod.

At this time, the first rotating rod is in an inclined state, the third positioning block supports the first rotating rod, and the ball on the first rotating rod is located in the groove. The third motor drives the third support rod to rotate, and the rotation of the third support rod drives the second sliding rod and the connecting block to move. The connecting block and the groove cooperate to drive the ball and the first rotating rod to rotate. During the rotation, the first rotating rod cooperates with the connecting block to drive the second sliding rod and the third detector to move towards the tunnel arch top.

[0045] The implementation principle of a tunnel detection device according to an embodiment of this application is as follows: When it is necessary to detect the surrounding rock of the tunnel, the first motor 311 causes the gear 312 to rotate on the surface of the rack 313. The gear 312 and the rack 313 cooperate to drive the rotating block 314 to rotate, thereby causing the first support rod 41 and the first sliding rod 42 to rotate. The first sliding rod 42 slides under the action of gravity. The first support rod 41 and the guide rod 43 cooperate to move the first sliding rod 42 away from the rotating block 314, thereby driving the first detector 315 to approach the tunnel arch foot and complete the detection of the tunnel arch foot. The second motor 323 drives the second support rod 324 to rotate, and the second support rod 324 drives the second detector 321 to rotate, thereby completing the detection of the tunnel arch waist.
