The invention provides an elevator car movement prevention protection mechanism. The elevator car movement prevention protection mechanism comprises a driving device and safety tongs. The driving device comprises a supporting plate. A driving wheel and a driven wheel are fixed to the supporting plate. The driving wheel and the driven wheel are externally sleeved with a first driving rope. The driving wheel is connected with a motor. Two transmission wheels are arranged on the supporting plate. The transmission wheels are externally sleeved with a second driving rope. The second driving rope isparallel to the first driving rope. Two door panel connecting plates are fixed to the second driving rope. One door panel connecting plate is connected with the upper side of the second driving rope,and the other door panel connecting plate is connected with the lower side of the second driving rope. One door panel connecting plate is connected with the first driving rope. The safety tongs and the driving device are provided with an intermediate connecting device. The driving device drives the safety tongs to be locked or unlocked through the intermediate connecting device. The elevator carmovement prevention protection mechanism is simple in structure and high in safety and can adopt mechanical linkage or electrical linkage. When an elevator door is opened, the door panel connecting plates move far away from each other, the safety tongs are locked, the door is opened, an elevator car is not fixed, and an accident that a passenger is injured when going in or out of the door cannot occur.
