Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figure 1 and Figure 2 As shown, this utility model provides a device for curing tunnel lining concrete. The curing device mainly includes a gantry structure 100, a working platform 200, a spraying mechanism 300, and a guiding mechanism 400.

[0038] Specifically, the gantry structure 100 has a top frame 110 and side frames 120. The two side frames 120 are spaced apart below the top frame 110 to form a passageway. A working platform 200 is located on the side of the gantry structure 100 opposite to the passageway. A spraying mechanism 300 is used to spray water mist onto the tunnel lining concrete.

[0039] A guide mechanism 400 is provided on the top of the gantry structure 100. The nozzles of the spraying mechanism 300 are mounted on the guide mechanism 400.

[0040] The guiding mechanism 400 extends along the passage direction of the channel. Furthermore, the guiding mechanism 400 extends out of the gantry structure 100 and can move the nozzle to the outside of the gantry structure 100.

[0041] Furthermore, wheels and a travel motor are provided on the lower part of the side frame 120. The output shaft of the travel motor is connected to the wheels via a chain and sprocket for transmission, enabling the maintenance device to travel.

[0042] The interval between walks and the distance walked can be set according to the maintenance cycle, thereby enabling the maintenance device to perform maintenance operations automatically.

[0043] Furthermore, the gantry structure 100 is made of welded I-beams.

[0044] In this embodiment, by setting a guiding mechanism 400 to move the nozzle relative to the gantry structure 100, the working coverage of the maintenance device can be increased, thereby reducing the frequency of movement of the maintenance device, improving maintenance efficiency, ensuring that the maintenance operation is carried out quickly and safely, and the working platform 200 can carry multiple people, enabling multiple people to work at the same time, thus improving the flexibility of the maintenance device.

[0045] Based on the above embodiments, another embodiment of the present invention introduces a device for curing tunnel lining concrete.

[0046] The guiding mechanism 400 mainly includes a track support 410 and a bracket 430. The track support 410 is fixed to the top frame 110. The track support 410 extends in a straight line, and its end protrudes from the gantry structure 100.

[0047] The bracket 430 is movably mounted on the track support 410 and can reciprocate along the extension direction of the track support 410.

[0048] The bracket 430 is provided with an arched rod 431. A plurality of nozzles are evenly distributed along the extending direction of the arched rod 431. The bracket 430 also includes a support rod perpendicular to the track support 410. The arched rod 431 is mounted on top of the support rod, such that the arched rod 431 extends above the top frame 110 to prevent it from colliding with the gantry structure 100 when it reciprocates on the track support 410.

[0049] In particular, the curved shape of the arch rod 431 corresponds to the curved shape of the tunnel roof, so that the spacing between all the nozzles on the arch rod 431 and the tunnel sidewall is equal, thereby ensuring that water is sprayed evenly onto the lining concrete and improving the quality of curing.

[0050] Furthermore, the guiding mechanism 400 also includes a guide rail 420 mounted on the track support 410. The guide rail 420 is arranged parallel to the track support 410. The bracket 430 is slidably connected to the guide rail 420.

[0051] The spraying mechanism 300 also includes a water tank 310 and a delivery pipe 320.

[0052] A water tank 310 is mounted on the side frame 120. A delivery pipe 320 is laid along the gantry structure 100. The delivery pipe 320 extends from the water tank 310 to the guide mechanism 400. One end of the delivery pipe 320 is connected to the water tank 310, and the other end is connected to the nozzle.

[0053] Furthermore, the guide mechanism 400 is also equipped with a motor. The motor is fixed to the bracket 430. In addition, the motor is connected to the track support 410 for driving the bracket 430 to move relative to the track support 410.

[0054] As the bracket 430 reciprocates along the track support 410, a tank chain is installed on the track support 410 to ensure that the wiring connecting the motor and the delivery pipe 320 connecting the nozzle move neatly along with the bracket 430. The wiring and delivery pipe 320 are both threaded through the tank chain.

[0055] Based on the above embodiments, another embodiment of the present invention introduces a device for curing tunnel lining concrete.

[0056] The working platform 200 includes a stacked platform 210 mounted on the side frame 120. Two stacked platforms 210 are symmetrically arranged on both sides of the gantry structure 100.

[0057] Furthermore, the stacked platform 210 consists of a first platform 211, a second platform 212, and a ladder 213.

[0058] The first platform 211 is mounted in the middle of the side frame 120. The second platform 212 is mounted on the top of the side frame 120.

[0059] The first platform 211 is provided with ladders 213 at both ends, extending towards the ground and the second platform 212 respectively.

[0060] Furthermore, the work platform 200 also includes a stepped platform 220 installed on the top frame 110. The stepped platform 220 is symmetrically distributed relative to the guide mechanism 400.

[0061] Furthermore, the maintenance device also includes a controller and temperature and humidity sensors.

[0062] Temperature and humidity sensors are used to acquire temperature and humidity data of the tunnel lining concrete. Several of these sensors are evenly distributed along the extension direction of the arched rod 431. During the curing process, the sensors collect temperature and humidity data at multiple points on the surface of the tunnel lining concrete and feed the collected data back to the controller.

[0063] Furthermore, a heater is installed inside the water tank 310 for adjusting the water temperature. The controller is electrically connected to the heater and is used to adjust the water temperature and heating time inside the water tank 310.

[0064] Furthermore, the maintenance device also includes a wind belt protection ring 111 installed on the top frame 110.

[0065] The wind belt protection ring 111 is equipped with several rolling elements to reduce friction between the gantry structure 100 and the wind belt.
