[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 2 As shown in the figure, this utility model embodiment proposes a tunnel maintenance trolley, including a base plate 1, a climbing component, and a railing 7. The bottom of the base plate 1 is provided with a moving mechanism 2, and the top of the base plate 1 is provided with multiple support columns 3. The top of the support columns 3 is provided with a top plate 4. A through groove is opened through the top plate 4. An installation box 5 is fixedly provided on the top of the base plate 1. The installation box 5 has an opening on one side. The top of the installation box 5 extends vertically upward through the through groove to the top of the top plate 4. A lifting basket 6 is slidably provided inside the installation box 5. The installation box 5 is also provided with a driving component for driving the lifting basket 6 to rise and fall. The climbing component assists workers to climb to the top of the installation box 5. The railing 7 is arranged along the circumferential direction of the top plate 4. During tunnel inspection, testing, or maintenance, this device moves within the tunnel via a mobile mechanism 2. Specifically, the mobile mechanism 2 can be selected from existing technologies, and the moving mechanism can also be casters. The device is connected via a rope, which then drives it to move within the tunnel. During the movement of this device, or after reaching a predetermined location, workers stand on the floor 1 or roof 4 and use infrared thermal imagers or humidity sensors to detect water seepage in the tunnel. If an anomaly is detected in a certain area, maintenance can be carried out using high-pressure water guns, grouting equipment, etc., placed on this device. If maintenance is needed on higher areas, the required equipment and materials are brought into the lifting basket 6, and then the drive assembly is activated. The lifting basket 6 is suspended to the height of the top plate 4 by the moving component, allowing workers to transport the required materials to the top plate 4. This facilitates maintenance of the tunnel inner wall at higher locations. When maintenance of the top of the tunnel inner wall is required, workers can climb to the top of the installation box 5 using the climbing component. At this point, the workers are directly below the top of the tunnel inner wall, making maintenance more convenient. The railing 7 protects the workers from falling from the top plate 4. The lifting basket 6, which allows workers and materials / equipment to be raised and lowered together, is installed inside the device. Commonly used materials and equipment are stored on the bottom plate 1. When maintenance of the tunnel inner wall at higher locations is required, workers can transport the necessary equipment and materials to the top plate 4 via the lifting basket 6, which is convenient, quick, and ensures worker safety.

[0020] like Figures 1 to 4As further shown, the climbing assembly includes: a conveyor belt 8, a receiving groove on one side of the mounting box 5 extending from the top plate 4, the conveyor belt 8 being vertically positioned within the receiving groove, and a station plate 9 fixedly mounted on one side of the conveyor belt 8. In this embodiment, the conveyor belt 8 is fitted onto a rotating roller and driven by a geared motor (not shown in the figure), which is existing technology. The specific principle is not elaborated here. This device only utilizes its ability to move objects in a straight line. By setting the station plate 9 on one side of the conveyor belt 8, when a worker needs to climb to the top of the mounting box 5, they can stand on the station plate 9. Then, the conveyor belt 8 transports the station plate 9, raising the worker's horizontal height to near the top of the mounting box 5, facilitating the worker's climb to the top of the mounting box 5 to maintain the top of the tunnel wall. When the worker needs to descend to the top plate 4, they stand on the station plate 9 again, and then the conveyor belt 8 reverses its direction.

[0021] like Figures 2 to 4 As shown, furthermore, handrails 10 are provided on both inner walls of the receiving groove. Preferably, the handrails 10 are hinged to the inner walls of the receiving groove. Workers are prone to instability when standing on the platform 9 during the lifting and lowering process. To prevent workers from falling off the platform 9, workers can hold onto the handrails 10 to ensure their balance during the lifting and lowering process.

[0022] like Figures 3 to 4 As shown, furthermore, a reinforcing support block 11 connects the bottom of the station plate 9 to the conveyor belt 8. The support block 11 strengthens the connection between the station plate 9 and the conveyor belt 8, while also increasing the support strength of the station plate 9, ensuring that the station plate 9 can bear the weight of the worker when standing on it. Specifically, the connection between the station plate 9 and the conveyor belt 8 can be achieved by integrally forming a connecting plate perpendicular to the station plate 9 on the station plate 9, and then bolting the connecting plate to the conveyor belt 8, thereby increasing the connection strength between the conveyor belt 8 and the station plate 9.

[0023] like Figure 1 and Figure 4As shown, the drive assembly further includes: a lifting rope 12 and a take-up roller 13. A mounting groove is provided on the top of the inner wall of the mounting box 5. The take-up roller 13 is horizontally and rotatably mounted in the mounting groove. There are several lifting ropes 12, one end of which is connected to the lifting basket 6, and the other end is connected to the take-up roller 13. The mounting box 5 is also equipped with a drive motor 14 for driving the take-up roller 13 to rotate. When lifting the lifting basket 6, the drive motor 14 is started, driving the take-up roller 13 to rotate. The take-up roller 13 winds up the lifting ropes 12, thereby pulling the lifting basket 6 upward. When the lifting basket 6 needs to be lowered, the drive motor 14 rotates in the opposite direction, causing the take-up roller 13 to release the lifting ropes 12. The lifting basket 6 descends under the action of gravity and finally lands on the base plate 1. In this embodiment, a lifting rope 12 is connected to each of the four corners of the lifting basket 6, and two lifting ropes 12 on the same side are combined into one strand and wound onto the take-up roller 13. Preferably, the lifting basket 6 is equipped with a counterweight.

[0024] Furthermore, a groove is provided on the top of the base plate 1, and the bottom of the mounting box 5 abuts against the bottom of the groove. The top of the inner wall of the suspended basket is on the same plane as the top of the base plate 1. Specifically, the top of the inner wall of the suspended basket is on the same plane as the top of the base plate 1, so that no step is formed between the suspended basket 6 and the base plate 1, making it more convenient to transport materials and equipment into the suspended basket 6.

[0025] like Figure 1 and Figure 2 As shown, furthermore, it also includes a shelf 15, with a hook 16 on one side of the shelf 15, which is hooked onto the fence 7. Specifically, the fence 7 is composed of multiple horizontal and vertical bars. After the hook 16 is hooked onto the fence 7, one side of the shelf 15 abuts against the fence 7. Workers can temporarily place repair tools and materials on the shelf 15. When repair tools need to be used multiple times, the process of retrieving repair tools is more convenient, which helps to improve work efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
