The present invention relates to the technical field of carbon fiber bracket production and molding, specifically to a carbon fiber bracket production and molding equipment and manufacturing method, including a mounting support and a swing support, wherein rotating pins are fixedly connected to both sides of the swing support, and the swing support is rotatably mounted on the mounting support through the rotating pins. The carbon fiber bracket production and molding equipment realizes the precise paving and tight fitting of different curved UAV brackets through flexible swing amplitude control and prepreg laying roller design. The equipment can change the paving angle at will to adapt to bracket surfaces with different curvatures, ensure that the carbon fiber prepreg paving is accurately attached to the surface of the UAV bracket, and improve the molding effect. At the same time, the setting of the elastic rolling assembly is adopted, which not only satisfies the tight fit between the material strip and the bracket, but also can synchronously adapt to different curved surfaces and maintain a constant pressure between the paving and the bracket, further improving the molding quality and effect of the carbon fiber bracket.

The invention discloses a fire alarm tricycle capable of automatically winding and unwinding a water hose, and relates to the field of rescue tricycles, the fire alarm tricycle comprises a tricycle body, an audible and visual alarm is mounted on the inner side of a carriage of the tricycle body, and a first storage mechanism is mounted on one side of the carriage of the tricycle body. According to the water hose cleaning device, a driving motor works to drive a rotating sleeve to rotate, a rotating disc and a second connecting rod rotate along with the rotating sleeve, a water hose is wound outside a plurality of fixing plates, and in the water hose winding and unwinding process, a first cleaning roller rotates synchronously to drive a second cleaning roller to rotate; the second cleaning roller and the first cleaning roller are matched to clean dirt on the outer surface of the water hose, scraping plates are attached to the outer surface of the second cleaning roller and the outer surface of the first cleaning roller and used for scraping the dirt on the second cleaning roller and the first cleaning roller, the scraped dirt enters the collecting box to be collected, and when the water hose is wound and unwound, the dirt on the outer surface of the water hose is removed. Sundries on the outer surface of the water hose are cleaned, so that the water hose is clean and tidy during storage, and the service life is prolonged.

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.
