[0047] See also Figure 1-11, this embodiment provides a technical solution based on the first embodiment: the spray system 8 includes a top spray bracket 43, a top spray pipe 44, a liquid inlet pipe 45, a transmission hose 46 and a side spray bracket 47, both sides of the top of the spray platform 7 are fixedly connected with the top spray bracket 43, the top of the top spray bracket 43 is fixedly connected with the top spray pipe 44, the middle of the top spray pipe 44 is fixedly connected with the liquid inlet pipe 45, the liquid inlet pipe 45 is connected to the liquid distribution pipe 12 through a transmission pipe, both ends of the top spray pipe 44 are fixedly connected with the transmission hose 46, both ends of the support frame 3 are fixedly connected with the side spray bracket 47, one end of the side spray bracket 47 is fixedly connected with the support box, and the middle of the support box is rotatably connected There is a carrying shaft 48, one end of the carrying shaft 48 is fixedly connected to an assembly cylinder 49, a side spray pipe 50 is slidably connected to the assembly cylinder 49, and the end of the transmission hose 46 away from the top spray pipe 44 is connected to the side spray pipe 50, the middle part of the assembly cylinder 49 is threadedly connected to a transmission screw 51, the end of the transmission screw 51 located inside the assembly cylinder 49 is fixedly connected to a contact pad 52, the end of the carrying shaft 48 located inside the support box is fixedly connected to a matching lock plate 53, the top of the support box is vertically slidably connected to a stop rod 54, and the bottom end of the stop rod 54 is connected to the matching lock plate 53, the top of the stop rod 54 is fixedly connected to a force sheet 55, and a coil spring 56 is fixedly connected between the bottom end of the force sheet 55 and the support box;

[0048] Preferably, a polished rod is fixedly connected to one side of the side spray pipe 50 close to the assembly tube 49, and the polished rod is slidably connected to the inside of the assembly tube 49. By setting the polished rod, the assembly of the assembly tube 49 can be stably formed;

[0049] In detail, multiple atomizing nozzles are fixedly connected to the outer sides of the top spray pipe 44 and the side spray pipe 50. By using the setting of the atomizing nozzles, the liquid inside the top spray pipe 44 and the side spray pipe 50 can be sprayed out in an atomized form, thereby reducing the overall spray blind area.

[0050] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0051] Working principle: the whole is moved into the tunnel, and a mobile power source is set to provide power to the whole. Then the booster pump 11 is started to extract the spraying liquid from the liquid storage tank 10 and inject it into the liquid inlet pipe 45, so that the liquid can flow along the top spray pipe 44 and be injected into the side spray pipe 50 through the transmission hose 46. Finally, it is sprayed to the second lining concrete of the tunnel through the top spray pipe 44 and the side spray pipe 50 to maintain it.

[0052] The hydraulic rod 25 can be started to pull the displacement push plate 26 to move, so that the guide ring 27 pushes the linkage rod 19 to slide under the support of the driving shaft 18 until the driving shaft 18 is stuck in the transmission shaft 14, and then the driving motor 22 is started to drive the central shaft 21 to rotate, so that the transmission spur gear 23 drives the reduction spur gear 24, and then drives the driving shaft 18 to rotate. Under the structural cooperation of the driving shaft 18 and the linkage rod 19, the linkage rod 19 can follow the driving shaft 18 to drive the transmission shaft 14 to rotate, and through the setting of the moving wheel 16, the whole body is driven to move in the tunnel;

[0053] After reaching the designated position, the hydraulic rod 25 is started to push the linkage rod 19 to move toward the transmission shaft 29 until the linkage rod 19 is stuck in the transmission shaft 29. Then, the drive motor 22 is started to cause the transmission spur gear 23 to shift the reduction spur gear 24, and the transmission shaft 29 is driven to rotate through the linkage rod 19. Under the connection of the transmission bevel gear 30 and the matching bevel gear 33, the power of the transmission shaft 29 can be transmitted to the output shaft 32 to drive the output shaft 32 to rotate. In combination with the setting of the threaded section 34, when the output shaft 32 rotates, , which can drive the guide plate 35 to move along the threaded section 34, and because the linkage plate A39 is connected between the guide plate 35 and the guide rod 37, when the guide plate 35 moves, the linkage plate A39 can be used to push the guide rod 37, so that the linkage plate A39 contacts the ground, and when the guide rod 37 moves downward, because the linkage plate B42 is connected between the flip frame 40 and the assembly ear 41, the flip frame 40 can be pushed by the linkage plate B42, so that the flip frame 40 contacts the ground, thereby increasing the friction with the ground and preventing the whole from slipping;

[0054] When the width in the tunnel changes, firstly, the transmission screw 51 is rotated to make the contact pad 52 disengage from the contact with the light rod, so that the light rod can slide inside the assembly tube 49, and then the side spray pipe 50 is pulled to retract it, and at the same time, the transmission screw 51 is tightened to make the contact pad 52 tightly squeezed out from the light rod, so that the side spray pipe 50 can be positioned. After the side spray pipe 50 is adjusted, it is necessary to pull up the force-bearing sheet 55 to make the anti-rotation clamping rod 54 move out of the matching lock plate 53, so as to unlock the carrying shaft 48, and then rotate the assembly tube 49 to adjust the spraying angle of the side spray pipe 50. After adjustment, the force on the force-bearing sheet 55 is released. When the force-bearing sheet 55 is pulled up, the coil spring 56 can be stretched. Then, when the force-bearing sheet 55 is released, the setting of the coil spring 56 can drive the anti-rotation clamping rod 54 to re-enter the matching lock plate 53 to lock the position of the carrying shaft 48.

[0055] In summary, the present invention can carry out curing operations of the secondary lining concrete in tunnel projects with different cross-sectional sizes through the overall structural coordination. The travel speed limiting device and the pressurized spraying device are used to ensure the coverage and uniformity of the secondary lining concrete spraying curing, achieve good curing effects, and ensure that the strength of the secondary lining concrete meets the design and specification requirements.
