[0025] The swing mechanism 3 includes a positioning seat 301, a swing arm 302, a lifting arm 303 and a lifting push rod 304. The positioning seat 301 is inserted into the left inner part of the mechanism seat 201, and the swing arm 302 is rotatably connected to the side of the positioning seat 301, the lifting arm 303 is inserted into the top of the swing arm 302, the lifting push rod 304 is fixedly installed inside the swing arm 302, and the top of the lifting push rod 304 is fixedly installed at the bottom of the lifting arm 303, the connecting gear 206 is rotatably connected to the side of the positioning seat 301, the steam spray rod 103 is fixedly installed on the top of the lifting arm 303, and the steam spray rod 103 is connected to the steam pipe.

[0026] In the disclosed embodiment, a swing gear 3021 is provided on the outside of the rotating shaft of the swing arm 302, and the gear teeth of the swing gear 3021 and the connecting gear 206 are meshed for transmission. The cross-sectional shape of the middle rod body of the driving rod 205 is a regular polygon, and a driving groove 2061 is provided inside the connecting gear 206. The rod body part of the driving rod 205 with a regular polygonal cross-section is inserted into the driving groove 2061. In use, the swing mechanism 3 can swing under the driving action of the drive control mechanism 2, thereby realizing the maintenance operation on the arched inner wall of the tunnel. When the swing motor 204 rotates, it can drive the driving rod 205 to rotate. When the driving rod 205 rotates, it can drive the connecting gear 206 to rotate through the driving groove 2061. When the connecting gear 206 rotates, it can drive the swing arm 302 to swing through the swing gear 3021, thereby realizing the swinging action of the swing mechanism 3.

[0027] In the embodiment of the present disclosure, a thread is provided on the outside of the rod body of the adjusting rod 203, and the adjusting rod 203 is screwed to the inside of the positioning seat 301 through the rod body thread. The swing radius of the swing mechanism 3 can be freely adjusted, and there are two adjustment methods. One is to adjust the swing radius under the premise that the maximum height of the swing stroke of the lifting arm 303 remains unchanged, and the second is to adjust the swing radius by changing the maximum height of the swing stroke of the lifting arm 303. The two adjustment methods can be selected as needed, and the coordinated use of the two adjustment methods can adapt to the stable maintenance operation of the inner wall of the tunnel with different shapes and arches, and the adaptability and flexibility are extremely strong. When the swing radius is adjusted under the premise that the maximum height of the swing stroke of the lifting arm 303 remains unchanged, the control motor 202 is controlled to rotate, and the adjusting rod 203 rotates synchronously when the adjusting motor 202 rotates. When the adjusting rod 203 rotates, it can be adjusted by the rod body thread. The groove drives the positioning seat 301 to move up and down inside the swing arm 302, thereby changing the center position of the swing action. After that, the lifting arm 303 is extended to the swing arm 302 by telescopically adjusting the length of the swing arm 302 by the lifting push rod 304 to adjust it to the original height (the height before adjustment). The adjustment operation is completed. After the adjustment is completed, the maximum height of the swing stroke of the lifting arm 303 will not change, only the swing radius of the swing mechanism 3 is changed. When the maximum height of the swing stroke of the lifting arm 303 is changed to adjust the swing radius, it is only necessary to telescopically adjust the length of the lifting arm 303 extending the swing arm 302 by the lifting push rod 304. After the adjustment is completed, the maximum height of the swing stroke of the lifting arm 303 will change, thereby changing the effective swing length composed of the swing arm 302 and the lifting arm 303, that is, changing the swing radius of the swing mechanism 3.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In the utility model, the maintenance trolley can drive the swing assembly to move in the tunnel through the installation assembly 1, and realize the maintenance operation of the secondary lining of the tunnel through the swing assembly. The height push rod 102 can drive the swing assembly to move up and down as a whole, so that after the spray direction of the steam spray rod 103 is set, the secondary lining maintenance operation of the vertical inner wall of the tunnel can be realized. When the arched inner wall needs to be maintained, the swing reset of the swing assembly is first adjusted to adapt to the shape of the inner wall of the tunnel. The swing radius of the swing mechanism 3 can be freely adjusted, and there are two adjustment methods. One is to adjust the swing radius under the premise that the maximum height of the swing stroke of the lifting arm 303 remains unchanged, and the other is to adjust the swing radius by changing the lift arm 303. The maximum height of the swing stroke of the lowering arm 303 is used to adjust the swing radius. Two control methods can be selected as needed, and the coordinated use of the two control methods can adapt to the stable maintenance operation of the inner wall of the tunnel with different shapes and arches. When the swing radius is adjusted under the premise that the maximum height of the swing stroke of the lifting arm 303 remains unchanged, the control motor 202 is controlled to rotate. When the adjusting motor 202 rotates, the adjusting rod 203 rotates synchronously. When the adjusting rod 203 rotates, it can drive the positioning seat 301 to move up and down inside the swing arm 302 through the rod body thread, thereby changing the center position of the swing action. Thereafter, the lifting arm 303 is extended and regulated by the lifting push rod 304. 02 is adjusted to the original height (the height before adjustment) by adjusting the length of the lifting arm 302. The adjustment operation is completed. In this adjustment method, the maximum height of the swing stroke of the lifting arm 303 will not change after the adjustment is completed, and only the swing radius of the swing mechanism 3 is changed. When the maximum height of the swing stroke of the lifting arm 303 is changed to adjust the swing radius, it is only necessary to adjust the length of the lifting arm 303 extending out of the swing arm 302 by telescopically adjusting the lifting push rod 304. In this adjustment method, the maximum height of the swing stroke of the lifting arm 303 will change after the adjustment is completed, thereby changing the effective swing length of the swing arm 302 and the lifting arm 303, that is, changing the swing radius of the swing mechanism 3. After completion, the maintenance operation can begin. The swing mechanism 3 can swing under the driving action of the drive control mechanism 2, thereby realizing the maintenance operation on the arched inner wall of the tunnel. When the swing motor 204 rotates, it can drive the driving rod 205 to rotate. When the driving rod 205 rotates, it can drive the connecting gear 206 to rotate through the driving groove 2061. When the connecting gear 206 rotates, it can drive the swing arm 302 to swing through the swing gear 3021, thereby realizing the swinging action of the swing mechanism 3. The reciprocating swinging action of the swing mechanism 3 can be realized by the regular forward and reverse rotation of the swing motor 204. Steam is sprayed onto the inner wall through the steam spray rod 103 for maintenance, and the maintenance is stable and efficient.

[0030] In another embodiment, the cross-sectional shape of the seat body of the positioning seat 301 is "T"-shaped, and a track groove 2011 is provided inside the mechanism seat 201. The positioning seat 301 is inserted into the track groove 2011. The track groove 2011 can limit the movement trajectory of the positioning seat 301 when adjusting the position, thereby avoiding the phenomenon of the device being stuck and failing due to skewing or twisting during movement, and the use is stable.
