This application discloses a cement-stabilized crushed stone layer structure, belonging to the technical field of crushed stone layers. The cement-stabilized crushed stone layer structure includes a grid frame, the interior of which is equipped with a filling skeleton assembly. The filling skeleton assembly includes multiple interconnected composite plates, with adjacent composite plates forming a honeycomb structure. The inner wall of the grid frame is fixedly connected to the adjacent composite plates. A through-hole is provided at the center of each composite plate. The honeycomb composite plates within the grid frame decompose the shear force under horizontal load into axial pressure, fully utilizing the compressive strength of concrete, effectively resisting pavement deformation, improving structural bearing capacity, and extending pavement service life. The honeycomb structure restricts the dispersion of crushed stone, facilitating compaction and shaping after cement pouring. The burr membrane within the anti-scattering holes forms a mechanical bond with the cement, enhancing the bond strength between the cement and the composite plates, ensuring tight fusion and improving the overall integrity of the pavement structure.

The application discloses a main beam glass fiber cloth layering hoist for wind power blade manufacturing, which comprises a lifting support, a shaft assembly rotatably installed on the lifting support, and a lifting hook assembly connecting the shaft assembly to the lifting support, the shaft assembly comprises a rotating shaft and a locking device locking the position of the rotating shaft, the locking device comprises a locking receiving part, a fixing part connected to the locking receiving part, and a locking piece matched with the locking receiving part, and the two ends of the glass fiber cloth abut against the fixing parts of a pair of locking devices and are fixed to the rotating shaft by the cooperation of the locking piece and the locking receiving part. The layering hoist can quickly, accurately and flatly lay the glass fiber cloth into a mold, reduces subsequent manual adjustment, saves the time and manpower for adjusting the glass fiber cloth after laying, thereby reducing the labor cost, ensuring the laying quality, and improving the laying efficiency.

The application discloses a tape roller device suitable for a full-automatic composite material tape laying equipment, which comprises a pair of roller mounting seats and a pressing shoe assembly arranged between the two roller mounting seats; each roller mounting seat is provided with a first pressing rod fixed at one end to swing, a second pressing rod hinged to the swinging end of the first pressing rod, a first telescopic assembly for pushing the first pressing rod to swing and a second telescopic assembly for pushing the second pressing rod; the extending end of the first telescopic assembly is hinged to the swinging end of the first pressing rod, and the fixed end of the first telescopic assembly is hinged to the roller mounting seat; the second pressing rods on the two roller mounting seats are provided with roller rollers crossing the tape placing plate. The application further provides a control method. The device provided by the application can effectively solve the technical problems of precise compaction and precise laying of prepreg.
