Abstract

Provided is a turnover-type opening and closing mechanism for a rail carriage front hatch. When a hood (1) needs to be completely opened, an unlocking steel cable (218) is pulled to lift a closed position lock tongue (212), such that the closed position lock tongue (212) is in contact with a closed position sensor (213). The closed position sensor (213) transmits a signal to a pneumatic control cabinet (4) to control a piston rod of a cylinder (202) to be pushed forward, such that a sliding plate (208) is driven to slide linearly forward. When a guide groove wheel (217) reaches a position at a curved section of a guide groove (204), the hood (1) acted upon by gravity and an air spring (210) turns downward, a central position sensor press plate (216) rotates with a support of the hood (1) to contact a central position sensor (215), and the pneumatic control cabinet (4) controls the piston rod of the cylinder (202) to retract, such that the hood (1) is driven to reach an ultimate open position and is closed automatically. The invention employs a driving force of a push rod and gravity to realize an opening and closing function of the entire front hatch, thereby achieving high reliability and low manufacturing and maintenance costs.
