It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a spray curing device for a secondary lining trolley, such as... Figure 1-5As shown, the spray curing device on the secondary lining trolley includes: a mounting frame 2 installed on the secondary lining trolley body 1, wherein a spray pipe 3 is fixedly installed on the mounting frame 2, and multiple spray heads 4 are provided on the spray pipe 3; a water tank 5 fixedly installed on the secondary lining trolley body 1, wherein a water pump 6 is provided on one side of the water tank 5, the inlet end of the water pump 6 is connected to the water tank 5, and a hose 7 is connected to the outlet end of the water pump 6, the hose 7 being connected to the spray pipe 3; and a filter mechanism provided on the inlet end of the water pump 6, wherein the filter mechanism is used to filter impurities in the spray water, and a cleaning mechanism is provided on the filter mechanism, wherein the cleaning mechanism is used to clean the impurities filtered by the filter mechanism.

[0023] In this embodiment, the device is equipped with a controller of model OMRON H5CX-A. The controller allows for the operation of the entire device. When spray curing is required inside the tunnel, the secondary lining trolley 1 moves the entire device. The controller activates the water pump 6, which draws water from the water tank 5 and directs it through the hose 7 into the spray pipe 3. The water is then sprayed into the tunnel through the spray head 4, thus curing the tunnel. While the water pump 6 is using the curing water, the filtration mechanism effectively filters impurities from the spray water, preventing them from clogging the water pump 6 and spray head 4, ensuring the normal operation of the device. The cleaning mechanism on the filtration mechanism automatically cleans the filtered impurities, avoiding the problem of reduced cleaning frequency due to manual cleaning negligence. This effectively prevents clogging of the filtration mechanism, reduces water flow resistance, and consequently reduces the workload of the water pump 6. The energy consumption is reduced, the overall work efficiency and reliability are improved, and the maintenance quality inside the tunnel is ensured. The entire device can perform spray maintenance inside the tunnel and can also perform self-cleaning, which improves the work efficiency and reliability of the spray maintenance device and ensures the maintenance quality inside the tunnel.

[0024] In a further preferred embodiment of the present invention, the filtration mechanism includes: a filter box 11 fixedly installed on the body 1 of the secondary lining trolley, the filter box 11 being connected to the water inlet of the water pump 6; and a plurality of filter screens 12 disposed in the filter box 11, the filter screens 12 being used to filter and remove impurities from the spray water.

[0025] In this embodiment, the spray water flowing out of the water tank 5 will first flow into the filter box 11 for pretreatment before entering the water pump 6. The multiple filter screens 12 with different mesh sizes in the filter box 11 can perform multi-stage filtration and impurity removal on the spray water. During the process of the spray water passing through the filter screen 12, the impurities in the water are effectively intercepted on the filter screen 12, thereby preventing impurities from entering the water pump 6 and avoiding the clogging of the spray head 4.

[0026] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a connecting shaft 13 rotatably mounted on the filter box 11 and the plurality of filter screens 12, a plurality of cleaning brushes 14 fixedly mounted on the connecting shaft 13, the brushes on the plurality of cleaning brushes 14 being in contact with the surface of the filter screens 12; and a second servo motor 15 fixedly mounted on one side of the outer wall of the filter box 11, the output shaft of the second servo motor 15 being connected to one end of the connecting shaft 13 via a coupling.

[0027] In this embodiment, when using the cleaning mechanism, the control valve on the inlet of the water pump 6 is first closed to prevent subsequent cleaning water from entering the water tank 5. The second servo motor 15 is started by the controller. The second servo motor 15 drives the connecting shaft 13 to rotate, which in turn drives the cleaning brush 14 to rotate and clean the filter screen 12. This avoids the problem of reduced cleaning frequency due to negligence when manually cleaning the filter screen 12, and can clean impurities on the filter screen 12 in a timely and efficient manner, preventing the filter screen 12 from becoming clogged.

[0028] In a further preferred embodiment of this utility model, an adjustment mechanism is provided on the secondary lining trolley body 1 and the mounting frame 2. The adjustment mechanism is used to adjust the spray angle of the spray head 4. The adjustment mechanism includes: two support plates 8 symmetrically fixedly installed on the secondary lining trolley body 1, and each of the two support plates 8 is rotatably mounted with a mounting shaft 9, and both mounting shafts 9 are fixedly connected to the mounting frame 2; a first servo motor 10 fixedly installed on one side of one of the support plates 8, and the output shaft of the first servo motor 10 is connected to one end of one of the mounting shafts 9 through a coupling.

[0029] In this embodiment, when the spray head 4 sprays and maintains the tunnel, the secondary lining trolley body 1 drives the spray head 4 to move within the tunnel. The controller starts the first servo motor 10 to perform certain forward and reverse rotations. The output shaft of the first servo motor 10 drives the mounting shaft 9 to rotate, which in turn drives the mounting frame 2 to rotate. Ultimately, the mounting frame 2 and the spray head 4 swing back and forth at a certain angle, thereby adjusting the spray angle. This allows for multiple sprayings at the same location, improving the spraying effect. The adjustment mechanism is used according to actual usage requirements.

[0030] In a further preferred embodiment of this utility model, a rinsing mechanism is provided on the filter box 11. The rinsing mechanism is used to rinse the filter screen 12. The rinsing mechanism includes: a plurality of rinsing pipes 16 fixedly installed on the filter box 11; a connecting pipe 17 fixedly installed on the rear outer wall of the filter box 11, the connecting pipe 17 being connected to the plurality of rinsing pipes 16; and a cleaning pump 18 fixedly installed on the rear outer wall of the filter box 11, the water outlet of the cleaning pump 18 being connected to the connecting pipe 17.

[0031] In this embodiment, when cleaning the filter screen 12, the inlet of the cleaning pump 18 is connected to the corresponding water source pipe, the cleaning pump 18 is started, and water with a certain pressure is delivered to each flushing pipe 16 through the connecting pipe 17. Finally, the water is sprayed out from the outlet on the flushing pipe 16 to powerfully flush the filter screen 12, improve the cleaning effect of the filter screen 12, and effectively prevent the filter screen 12 from clogging.

[0032] In a further preferred embodiment of the present invention, the filter box 11 is provided with a plurality of drain pipes 19, which are used to drain the water used to clean the filter screen 12. A horizontal pipe 20 is fixedly installed on the rear outer wall of the filter box 11, and the horizontal pipe 20 and the plurality of drain pipes 19 are all connected.

[0033] In this embodiment, when rinsing the filter screen 12, the horizontal pipe 20 is opened, and the cleaning water is discharged from the filter box 11 through the drain pipe 19 and the horizontal pipe 20.

[0034] In a further preferred embodiment of this utility model, control valves are provided on both the horizontal pipe 20 and the water inlet end of the water pump 6.

[0035] In this embodiment, the control valve facilitates the control of the horizontal pipe 20 and the water inlet of the water pump 6. When cleaning the filter screen 12, the control valve on the horizontal pipe 20 needs to be opened to facilitate the discharge of cleaning water from the filter box 11. At the same time, the control valve on the water inlet of the water pump 6 needs to be closed to prevent cleaning water from entering the water tank 5.

[0036] In summary, compared with related technologies, this device can perform spray curing inside tunnels and also has a self-cleaning function, which improves the working efficiency and reliability of the spray curing device and ensures the quality of maintenance inside the tunnels.
