High-speed rail box girder top plate pressing and wiping device for girder yard

The invention belongs to the field of prefabrication of high-speed rail box girders, and particularly relates to a high-speed rail box girder top plate pressing and wiping device for a girder yard. Comprising a track type truss, walking units fixed to the two ends of the track type truss, a troweling plate system mounting frame arranged below the middle of the track type truss, height adjusting mechanisms mounted on the two sides of the troweling plate system mounting frame, a troweling plate track structure hung below the height adjusting mechanisms, and a plurality of troweling plate units capable of transversely moving in the troweling plate track structure. The transmission chain system is used for driving the trowelling plate unit; the troweling plate units are strung together through a chain, and the troweling plate units on the leftmost side and the rightmost side are connected with a chain of the transmission chain system; according to the high-speed rail box girder top plate pressing and trowelling d
