Description

Technical Field

[0001] The invention belongs to the field of tunnel maintenance, and in particular relates to a highway tunnel environment detection vehicle. Background Art

[0002] Tunnels are a vital component of modern transportation and infrastructure construction, but their safety and maintenance have long been a challenge. Traditional highway tunnel environmental monitoring and maintenance often present the following challenges: 1. Maintenance personnel are required to regularly enter the tunnel to conduct environmental inspections and equipment repairs. This large-scale investment of manpower and equipment resources for tunnel environmental monitoring and maintenance is not only inefficient but also increases operating and maintenance costs, placing financial pressure on transportation authorities or tunnel operators. 2. Maintenance personnel need to enter the tunnel for inspections and repairs, facing a high-risk environment and potential threats from environmental factors such as toxic gases and smoke, increasing safety risks for personnel. 3. Traditional inspection and maintenance methods require interrupting tunnel traffic or temporarily closing the tunnel, causing inconvenience and delays to transportation. 4. Due to the complex internal environment of the tunnel, manual inspections struggle to obtain accurate environmental data at every location in the tunnel, potentially leading to incomplete monitoring or missing abnormalities. Summary of the Invention

[0003] In response to the defects in the existing technology, the present invention provides a highway tunnel environment detection vehicle to solve the problems of low efficiency in comprehensive tunnel detection during traditional tunnel maintenance, requiring a large amount of manpower and material resources, and the need to close the tunnel during the detection process, which affects the normal passage of vehicles.

[0004] To achieve the above objectives, the present invention provides a highway tunnel environment monitoring vehicle comprising: a first rotating platform, a lifting arm, a mounting base, a telescopic arm, a detection terminal, and a drive element. The first rotating platform is fixedly mounted to the vehicle body, and the lifting arm is fixedly mounted to the first rotating platform, with the first rotating platform driving the lifting arm's rotation. The mounting base is fixedly mounted at the lifting end of the lifting arm, the telescopic arm is hinged to the mounting base, and the detection terminal is mounted at the telescopic end of the telescopic arm. The drive element is configured to rotate the telescopic arm about the mounting base. The drive element may be a hydraulic cylinder, the cylinder body of which is hinged to the mounting base, and the telescopic end of the hydraulic cylinder is hinged to the telescopic arm. The extension and retraction of the hydraulic cylinder drives the telescopic arm's rotation, thereby adjusting the position of the detection terminal relative to the tunnel wall. The detection terminal includes a camera, a thermal radiation sensor, a crack detector, and a marking gun. The camera is configured to capture images of the tunnel environment, which can be used to determine whether there are obstacles in the tunnel, whether tunnel lights are damaged, and whether the protective layer on the tunnel wall has detached. The thermal radiation sensor is used to collect thermal radiation information from the tunnel environment. This information can be used to determine whether the tunnel wall is leaking or whether the pipes are damaged. The crack detector is used to collect crack information from the tunnel wall. The crack detector can be an X-ray detector. This information can be used to determine whether the tunnel wall is cracked. The marking gun is used to mark the tunnel wall.

[0005] The inspection vehicle travels along one lane of the tunnel. The detection terminal on the inspection mechanism collects various data on the tunnel sidewalls and tunnel roof as it travels. Vehicles on the other side of the tunnel can pass normally. This allows for safe monitoring of the tunnel environment without disrupting normal traffic. If any tunnel wall requires maintenance or reinforcement, a marking gun is used to mark the required area. The inspection vehicle stops, safety warning signs are placed in front and behind the vehicle, and repairs are carried out on any areas requiring maintenance. The entire tunnel inspection process requires minimal personnel, resulting in high efficiency and no disruption to normal traffic.

[0006] Optionally, several groups of telescopic arms are hinged on the mounting base, and several of the telescopic arms can be fanned out around the mounting base. When the telescopic arms are unfolded, the detection terminals at the ends of the telescopic arms are also unfolded. After all the telescopic arms are unfolded at the same time, the detection range of the detection terminal can cover the right tunnel wall and the top of the tunnel on the right side of the inspection vehicle at the same time. Multiple detection terminals can realize detection at the same time, with a wider detection range and higher efficiency. The inspection vehicle completes the tunnel inspection while driving slowly. The inspection vehicle only needs to drive back and forth in the tunnel once to complete the full-scale inspection of the entire tunnel wall. This greatly improves the inspection efficiency.

[0007] Optionally, the highway tunnel environmental inspection vehicle further includes a reinforcement mechanism and a lifting platform. The lifting platform is fixedly mounted on the vehicle body, and the first rotating platform is positioned between the lifting platform and the vehicle head. The highway tunnel environmental inspection vehicle further includes a reinforcement mechanism comprising a second rotating platform, an actuator arm, and an anchor drill. The second rotating platform is fixedly mounted on the lifting platform, and the actuator arm is mounted on the second rotating platform. The anchor drill is located at the end of the actuator arm. If the inspection vehicle detects cracks on the tunnel wall during operation, a marking gun marks the cracked area. The crack detector performs a detailed re-inspection of the marked area to determine if reinforcement is required. The actuator arm controls the anchor drill to drive anchor bolts in the areas requiring reinforcement. The anchor drill can be an automatic grouting anchor drill capable of automatically driving and grouting anchor bolts. The reinforcement mechanism on the inspection vehicle enables on-site inspection, assessment, and reinforcement, improving tunnel maintenance efficiency.

[0008] Optionally, the highway tunnel environment inspection vehicle further includes an anchor rod retrieval mechanism, comprising an anchor rod rack, a transmission assembly, a motor, and a retrieving roller. The anchor rod rack is provided with a cargo box for storing anchor rods, the cargo box having a slope at its bottom, a discharge port at its bottom, and a retrieving roller rotatably mounted at the discharge port. The motor is fixedly connected to the anchor rod rack, and the motor is connected to the retrieving roller via the transmission assembly. This allows for the storage of a large number of anchor rods and facilitates their retrieval. The anchor rods slide down the slope, and the anchor rods at the discharge port enter the retrieving roller, allowing for quantitative retrieval of anchor rods via the retrieving roller. The retrieving roller is provided with a U-shaped groove, the size of which is larger than the outer diameter of the anchor rod, and the U-shaped groove can only accommodate one anchor rod. The anchor rod that enters the U-shaped groove falls onto the retrieving platform as the retrieving roller rotates, making it convenient for the operator or the robot arm to pick up the anchor rod. The anchor rod is removed from the retrieving platform and then installed on the anchor drilling rig. If the operator takes the anchor rod from the retrieving platform and then installs it on the anchor drilling rig, only one operator is required to complete the removal and installation of the anchor rod. At the same time, the anchor drilling rig is operated to drive the anchor rod into the tunnel wall. If the robot arm is used to take the anchor rod from the retrieving platform and then install it on the anchor drilling rig, the entire tunnel wall reinforcement process can be fully automated.

[0009] Optionally, the transmission assembly includes a driving pulley and a driven pulley, wherein the driving pulley is coaxially fixedly mounted on the output shaft of the motor, the driven pulley is coaxially fixedly connected to the pick-up roller, and the driving pulley and the driven pulley are connected via the belt transmission. The transmission path is clear, and the use of a belt transmission is safe, reliable, and low-cost.

[0010] Optionally, the actuator arm includes a support column, a first telescopic rod, and a second telescopic rod. One end of the support column is hinged to the second rotating platform, and the other end of the support column is hinged to the anchor drill. One end of the first telescopic rod is hinged to the second rotating platform, and the other end of the first telescopic rod is hinged to the support column. One end of the second telescopic rod is hinged to the support column, and the other end of the second telescopic rod is hinged to the anchor drill. This allows for multi-angle adjustment of the anchor drill, facilitating tunnel reinforcement.

[0011] Optionally, horizontal telescopic rods are fixedly mounted on both sides of the vehicle body, and support feet are detachably mounted on the ends of the horizontal telescopic rods, thereby increasing the stability of the inspection vehicle when reinforcing the tunnel.

[0012] Optionally, the lifting platform is provided with a guardrail to protect the personal safety of the operator on the lifting platform. The guardrail is removable. When the tunnel needs to be reinforced, the guardrail around the anchor drilling rig can be removed to prevent interference with the anchor drilling rig's operation.
