A new type of buoy of navigation float's mooring ring installation structure
The utility model relates to a novel navigation mark buoy's mooring ring mounting structure, including buoy body and mooring ring, buoy body buoy outer wall, top bulkhead, bottom bulkhead and steel baffle, top bulkhead and bottom bulkhead are welded in the upper and lower sides of buoy outer wall respectively, the steel baffle is provided with several and is welded in buoy outer wall, the upper and lower ends of steel baffle are welded on top bulkhead and bottom bulkhead respectively, and the mooring ring is provided with several and is welded on the bottom of bottom bulkhead and steel baffle respectively. The utility model welds the mooring ring at the connecting place of the steel baffle and bottom bulkhead in the buoy, because the steel baffle itself has higher structural strength and penetrates the buoy interior, uses as the welding base of mooring ring, can enhance the bearing capacity of connecting part significantly. The steel baffle plays the role of the reinforcing rib when being stressed, effectively disperses the tensile force, torsional load and impact stress that anchor chain transmits, avoids stress concentration and leads to the weld cracking.

An electric vertical injection molding machine with a mold locking mechanism
The application provides an electric vertical injection molding machine with a mold locking mechanism, and relates to the technical field of injection molding equipment. The electric vertical injection molding machine with the mold locking mechanism comprises a rack, a lower mold plate fixedly arranged at the upper portion, a movable mold plate capable of sliding up and down above the lower mold plate, and a pull rod connecting the rack and the lower mold plate. The top of the rack is provided with an upper support frame. A composite mold locking driving mechanism and a self-balancing gravity compensation mechanism are installed on the upper support frame. The composite mold locking driving mechanism comprises a main driving servo motor arranged in a biasing mode. A speed reducer is connected to the main driving servo motor. In the application, high-speed stable mold closing is realized through gravity compensation and self-adaptive leveling, and the lead screw is protected. The combination of the mechatronic and hydraulic separation layout makes the servo and the hollow hydraulic responsible for mold opening and closing and center mold locking injection, respectively. The electric precision and the hydraulic large mold locking force are combined, and the molding precision and the service life of the equipment are effectively improved.

Soft soil stratum shield tunnel assembly type vertical shaft foundation reinforcement system and construction method
This invention discloses a prefabricated vertical shaft foundation reinforcement system and construction method for shield tunnels in soft soil strata, relating to the field of vertical shaft foundation reinforcement technology. The system includes an external retaining system forming a water-stop curtain to prevent water and soil infiltration. The foundation reinforcement system comprises a first reinforcement structure and a second reinforcement structure, which work together to reinforce the foundation around the shaft, strengthening the soft soil around the shaft and increasing the bearing capacity of the foundation. This prevents local settlement of the foundation under shaft pressure, avoiding shaft tilting, deformation, and segment cracking. A load-bearing and anti-buoyancy structure extends through the first and second reinforcement structures to the stable strata below the shaft, and the reinforcement system is subjected to overall stress through a shaft opening ring beam, ensuring overall stability of the shaft. This system can adapt to extreme working conditions of large-diameter prefabricated vertical shafts in complex terrains such as riverbanks, water-rich areas, and soft soil.
