The vibrating block 4 is an overall rectangular block, and the front contact surface of the vibrating block 4 is an arc surface. The vibrating block 4 and the plastering board 8 are at the same end of the setting board 1. With such a setting, it is convenient for the two to cooperate with each other, first tamping the curved surface of the tunnel and then leveling it.

[0035] A connecting plate 33 is fixedly arranged in the middle of the setting board 1 on one side of the rack column 32. One end of a matching rod 34 is arranged on the connecting plate 33. The matching rod 34 includes an integrally arranged meshing tooth part 341 and a limiting rod part 342. The meshing tooth part 341 is hinged on the connecting plate 33 and meshes with the rack column 32. A guiding groove 3421 is opened on the limiting rod part 342.

[0036] A mounting frame 35 is detachably and fixedly arranged on the setting plate 1 on the side of the connecting plate 33 away from the rack column 32. A rotating ring block 36 is rotatably arranged in the upper side of the mounting frame 35 through a bearing. Convex blocks are circumferentially and evenly arranged on the outer side wall of the rotating ring block 36. A toroidal worm 37 is arranged in the mounting frame 35 on one side of the rotating ring block 36. The toroidal worm 37 meshes with the convex blocks. A driving motor 38 is coaxially arranged at the end of the toroidal worm 37. A circular plate 39 is detachably and fixedly arranged at the top of the rotating ring block 36. A distance adjusting assembly 5 is arranged on the circular plate 39. A driving column 310 is further included. One end of the driving column 310 is connected to the distance adjusting assembly 5, and the other end of the driving column 310 is arranged in a guiding groove 3421 on the limiting rod part 342.

[0037] In order to be able to adjust the reciprocating process distance of the reciprocating vibrating and stamping assembly, so as to adjust the depth of stamping on the concrete, in this embodiment, refer to Figures 3-5 , a distance adjusting assembly 5 is arranged on the reciprocating vibrating and stamping assembly 3. The distance adjusting assembly 5 includes an adjusting motor 51. A rectangular groove is formed in the middle of the top surface of the circular plate 39. The adjusting motor 51 is fixedly arranged in the rectangular groove. The adjusting motor 51 is coaxially provided with a threaded rod 52. The threaded rod 52 penetrates through the driving column 310 and is threadedly connected thereto. A rotating support member is arranged on the circular plate 39 at the other end of the threaded rod 52. A sliding limiting groove 53 is formed at the projection position of the threaded rod 52 on the circular plate 39. A slider 54 is fixedly arranged at the end of the driving column 310. The slider 54 is slidably arranged in the sliding limiting groove 53.

[0038] It can be understood that starting the adjusting motor 51 drives the threaded rod 52 to rotate, thereby adjusting the position of the driving column 310 relative to the center of the circular plate 39. After adjustment, the adjusting motor 51 is turned off, and then the driving column 310 is fixed. When the rotating ring block 36 rotates to drive the circular plate 39 to rotate, the driving column 310 will also rotate around the circular plate 39, driving the mating rod 34 sleeved thereon to swing, and further driving the rack column 32 meshing with the bottom of the mating rod 34, so that the vibrating and stamping block 4 at the front end vibrates and compacts the concrete.

[0039] The using method of the sliding trowel device for the wet shotcreting machine of the present utility model: When it is necessary to finely adjust the axial position of the trowel 8, loosen the bolt, pull out the short rod of the trowel 8 to a suitable position, tighten the bolt, and then drive the construction vehicle to the middle of the tunnel pavement, and drive the trowel device arranged at the front end through the swinging robotic arm on the construction vehicle to perform a swinging operation.

[0040] First, the reciprocating vibrating component 3 drives the vibrating block 4 to compact the concrete on the tunnel. The driving motor 38 is started, the toroidal worm 37 drives the rotating ring block 36 to rotate, and then drives the circular plate 39 to rotate. The adjusted and fixed driving column 310 will also rotate around the circular plate 39, driving the mating rod 34 sleeved thereon to swing, and then driving the rack column 32 meshed with the bottom of the mating rod 34, so that the vibrating block 4 at the front end compacts the concrete. At the same time, the screeding plate 8 arranged at the bottom of the same-side setting plate 1 levels the concrete.

[0041] When it is necessary to adjust the reciprocating process distance of the reciprocating vibrating component 3 to control the depth of compaction of the concrete, the adjusting motor 51 can be started at any time to drive the threaded rod 52 to rotate, and then adjust the position of the driving column 310 relative to the center of the circular plate 39. After adjustment, the adjusting motor 51 is turned off to fix the changed driving column 310, thereby affecting the reciprocating displacement distance of the rack column 32. This device can make the concrete surface smoother and more even, improving the aesthetics and service life of the concrete. At the same time, it can effectively prevent cracks from appearing on the concrete surface, improving the durability and stability of the concrete. In addition, the leveled concrete surface is flatter, which is beneficial to the setting-out work in subsequent construction, improving the construction efficiency and quality.
