[0018] Example 1

[0019] like Figures 1 to 3 As shown, this utility model proposes a tunnel lining maintenance device, including an electric trolley 1, a support column 302, a maintenance mechanism, and a water delivery mechanism. A water storage tank 2 is installed at the top of the electric trolley 1, and an installation groove is formed in the middle of the water storage tank 2. The support column 302 is adjustablely installed in the installation groove along the height direction of the electric trolley 1. The maintenance mechanism consists of a first arc-shaped box 4 installed at the top of the support column 302, two sets of second arc-shaped boxes 401 hinged to the first arc-shaped box 4, and an adjustment component installed on the support column 302. The two sets of second arc-shaped boxes 401 are driven by the adjustment component to rotate synchronously along the first arc-shaped box 4. Multiple sets of universal nozzles 402 are evenly installed on the first arc-shaped box 4 and the second arc-shaped box 401. The output end of the universal nozzle 402 corresponds to the tunnel lining, and the angle of the universal nozzle 402 relative to the first arc-shaped box 4 or the second arc-shaped box 401 is adjustable. As is the existing technology, after the adjustment components are adjusted, each set of universal nozzles 402 can be fine-tuned to ensure that the water sprayed by the universal nozzles 402 can fully contact the tunnel lining. Infrared distance sensors 101 are installed on the top of the first arc-shaped box 4, the bottom of the side wall of the second arc-shaped box 401, and the left and right side walls of the electric trolley 1. The infrared distance sensors 101 are electrically connected to the controller and are used to detect the distance from the first arc-shaped box 4 or the second arc-shaped box 401 to the lining, so that the curing of the lining by multiple sets of universal nozzles 402 is more uniform, or to detect the distance from the electric trolley 1 to the sides of the lining, so as to avoid the electric trolley 1 from deviating and affecting the uniformity of curing. The water delivery mechanism is set on the top of the electric trolley 1. The input end of the water delivery mechanism is connected to the water storage tank 2, and the output end of the water delivery mechanism is connected to the first arc-shaped box 4 and the two sets of second arc-shaped boxes 401.

[0020] Furthermore, a lifting seat 301 is installed at the bottom of the support column 302, and a first lifting component 3 is provided between the lifting seat 301 and the bottom of the mounting groove. The first lifting component 3 is a hydraulic rod. Two sets of guide grooves are symmetrically opened on the mounting groove, and two sets of sliders are symmetrically installed on the lifting seat 301. The sliders are slidably connected with the corresponding guide grooves to improve the adjustment stability between the support column 302 and the mounting groove.

[0021] Furthermore, a liquid level sensor is installed inside the water storage tank 2, and an alarm is installed on the water storage tank 2. The liquid level sensor and the alarm are electrically connected to the controller. The liquid level sensor monitors the water level in the water storage tank 2 and transmits the detection information to the controller in a timely manner. The controller then activates the alarm to remind the workers and stops the equipment operation.

[0022] Furthermore, the adjustment assembly includes a second lifting member 304, a movable seat 305, and an adjusting arm 306; the second lifting member 304 is disposed in the inner cavity of the support column 302, and a door body is hinged to the support column 302. The door body is connected to the support column 302 by a latch, and the second lifting member 304 is a hydraulic rod; the movable seat 305 passes through the support column 302 and is slidably connected to it, and the bottom end of the movable seat 305 is connected to the output end of the second lifting member 304. Two sets of guide ports 3 are symmetrically opened on the support column 302. 03. The movable seat 305 is slidably connected to two sets of guide ports 303 to guide the movable seat 305 and improve its movement stability. Two sets of adjusting arms 306 are provided, and the two sets of adjusting arms 306 are symmetrically hinged to the movable seat 305. The other end of the two sets of adjusting arms 306 is respectively hinged to the corresponding second arc-shaped box 401. Wear-resistant bushings are provided at the hinge points of the two sets of adjusting arms 306 with the movable seat 305 and the second arc-shaped box 401 to reduce wear caused by long-term rotation and extend service life.

[0023] Furthermore, the water delivery mechanism includes a high-pressure pump 5; the high-pressure pump 5 is installed at the top of the water storage tank 2, the input end of the high-pressure pump 5 is connected to the water storage tank 2 through a hose, the output end of the high-pressure pump 5 is connected to a diversion pipe 501 through a hose, the diversion pipe 501 is installed on the support column 302, the output end of the diversion pipe 501 is connected to the first arc-shaped box 4 and two sets of second arc-shaped boxes 401 respectively through hoses, and a check valve is installed on the hose to prevent water backflow.

[0024] In this embodiment, the controller activates the first lifting component 3 to drive the lifting seat 301 to move up or down along the mounting groove for adjustment. This allows the support column 302 to slide along the height direction of the electric trolley 1, thereby adjusting the overall height of the first arc-shaped box 4 and the second arc-shaped box 401. The controller activates the second lifting component 304 to drive the moving seat 305 to slide up or down along the guide opening 303. This, in turn, causes the two sets of adjusting arms 306 to rotate the corresponding two sets of second arc-shaped boxes 401 along the hinged ends with the first arc-shaped box 4, further adjusting the distance between the second arc-shaped box 401 and the tunnel lining, thus allowing the first arc-shaped box 401 to move up or down. Multiple sets of universal nozzles 402 on the two arc-shaped boxes 401 are adjusted to suitable positions relative to the tunnel lining, so that the first arc-shaped box 4 and the second arc-shaped box 401 can adapt to tunnel linings of more sizes. The electric trolley 1 is started by the controller to make this device move automatically in the tunnel. Through the real-time monitoring of multiple sets of infrared distance sensors 101, the electric trolley 1 is kept in a suitable position in the tunnel. At the same time, the high-pressure pump 5 is started by the controller to pump water from the water storage tank 2 and deliver it to the diversion pipe 501, and then send it to the first arc-shaped box 4 and the two sets of second arc-shaped boxes 401 respectively. Finally, the water is sprayed onto the lining by multiple sets of universal nozzles 402 to complete the curing.

[0025] Example 2

[0026] like Figure 2 and Figure 4 As shown, the tunnel lining maintenance device proposed in this utility model, compared with Embodiment 1, includes an extension component in the adjustment assembly. Two sets of extension components are provided, each set mounted on a corresponding second arc-shaped box 401. Each extension component includes a U-shaped seat 6, an extension tube 601, and a connecting tube 604. The U-shaped seat 6 is mounted on the bottom end of the second arc-shaped box 401, and an adjustment rod 602 is threadedly connected to the U-shaped seat 6. The top end of the extension tube 601 is rotatably connected to the U-shaped seat 6, and the end of the adjustment rod 602 abuts against the extension tube 601. A rotating rod is installed on the extension tube 601. The end of the rotating rod away from the U-shaped seat 6 is rotatably connected to the U-shaped seat 6 via a bearing. An abutment seat is provided at the end of the adjusting rod 602. The abutment seat is a rubber block to increase the friction at the abutment point between the adjusting rod 602 and the extension tube 601. A counterweight seat 603 is provided at the bottom of the extension tube 601. A universal nozzle 402 is connected to the side wall of the extension tube 601 near the water storage tank 2. Multiple sets of universal nozzles 402 are provided. A connecting pipe 604 is installed between the extension tube 601 and the corresponding second arc-shaped box 401.

[0027] It should be noted that the hoses between the diversion pipe 501 and the first arc-shaped box 4 and the second arc-shaped box 401, as well as the connecting pipe 604, are all equipped with flow regulating valves to avoid uneven water pressure at each nozzle 402 due to differences in branch resistance, and to further ensure uniformity of maintenance.

[0028] In this embodiment, the adjusting rod 602 is rotated so that the abutment at its end no longer abuts against the extension pipe 601. At this time, the extension pipe 601 can rotate freely along the U-shaped seat 6. After the second arc-shaped box 401 is adjusted at the right angle relative to the tunnel lining, the adjusting rod 602 is rotated to drive the abutment to abut against the extension pipe 601, thereby locking the extension pipe 601 relative to the U-shaped seat 6. This prevents the extension pipe 601 from swaying along the U-shaped seat 6 during the movement of the electric trolley 1. At this time, the extension pipe 601 is adjusted to the right position relative to the tunnel lining sidewall, so that the multiple sets of universal nozzles 402 on the extension pipe 601 can spray water on the tunnel lining sidewall, further improving the maintenance effect.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
