[0032] Working principle and usage process of the utility model: The staff places the trench cover plate forming mold 8 on the fixed plate 7. Then, the staff installs the L-shaped plug board 21 to limit and fix the trench cover plate forming mold 8. Next, the staff pours concrete materials into the trench cover plate forming mold 8 to prepare the trench cover plate. After the concrete materials are poured, the staff starts the vibration motor 9. The vibration motor 9 works to drive the fixed plate 7 and the trench cover plate forming mold 8 to vibrate, thereby effectively removing the air bubbles generated during the pouring of the concrete materials and facilitating the preparation of the trench cover plate;

[0033] After the concrete materials poured into the trench cover plate forming mold 8 are vibration-molded, the staff removes the L-shaped plug board 21. Then, the staff starts two reduction motors 13. The reduction motors 13 work to drive the transmission screw 12 to rotate. The transmission screw 12 rotates to drive the transmission slider 14 to move. The U-shaped bracket 15 moves synchronously with the two transmission sliders 14. When the U-shaped bracket 15 moves directly above the fixed plate 7, the staff turns off the two reduction motors 13 and starts the electric hydraulic push rod 16. The electric hydraulic push rod 16 works to push the hanging plate 18 downward. During the downward movement of the hanging plate 18, the staff pulls the hanging plate 18 outward so that the hook 34 of the hanging plate 18 is located outside the L-shaped pull plate 10. When the hook 34 of the hanging plate 18 is located below the outside of the L-shaped pull plate 10, the staff releases the hanging plate 18 to allow the hanging plate 18 to naturally rotate to a vertical state. Then, the staff restarts the electric hydraulic push rod 16 to move the hanging plate 18 upward. During the upward movement of the hanging plate 18, the hook 34 of the hanging plate 18 contacts the L-shaped pull plate 10, thereby being able to lift the trench cover plate forming mold 8;

[0034] After the trench cover plate forming mold 8 is lifted, the staff restarts the two reduction motors 13 to move the U-shaped bracket 15 above the blanking opening 3. The trench cover plate forming mold 8 moves synchronously with the U-shaped bracket 15. Then, the staff starts the electric hydraulic push rod 16 to move the hanging plate 18 downward. The trench cover plate forming mold 8 moves synchronously with the hanging plate 18 downward. When the trench cover plate forming mold 8 contacts the ground (support surface), the staff pulls the hanging plate 18 outward and restarts the electric hydraulic push rod 16 to move the hanging plate 18 upward, thereby realizing the blanking of the trench cover plate forming mold 8 and facilitating the installation of a new trench cover plate forming mold 8 on this vibration platform for the prefabrication of another trench cover plate, which is beneficial to improving the service performance of this vibration platform.
