Detailed Description
The invention is described in further detail below with reference to the drawings and specific examples.
As shown in fig. 1 and 2, the inverted arch concrete plastering device of the present embodiment includes a plastering roller 1 and two rows of guide rails 2, the guide rails 2 are arc rails 21, the two rows of arc rails 21 are arranged in parallel along the depth direction of the inverted arch (vertical paper direction in fig. 1), and the plastering roller 1 is movably disposed on the two rows of arc rails 21. Wherein, a power wheel can be arranged on the plastering roller 1, so that the plastering roller 1 can actively move along the guide track 2, or a driving mechanism can be arranged on the guide track 2, the driving mechanism drives the plastering roller 1 to move along the guide track 2, and the driving mechanism can be, for example, a chain wheel and a chain, a transmission chain wheel is correspondingly arranged on the plastering roller 1, or a hydraulic cylinder and the like; the plastering roller 1 can realize active rotation by the rotary driving force, or passively rotate after contacting with the concrete surface in the moving process.
