The invention relates to a safety locking device which comprises a machine frame, a locking pin is installed on the machine frame in a guiding mode, and the locking pin is provided with a locking position and an unlocking position. A driving handle with the rotating axis extending in the left-right direction is further hinged to the machine frame, a rotating piece synchronously rotating along with the driving handle is connected to the driving handle, the rotating piece and the locking pin are hinged through a pin shaft, and a matching structure used for enabling the rotating piece to drive the locking pin to move front and back is arranged on the rotating piece or the locking pin. The rack is further provided with a travel switch used for being electrically connected with equipment to be locked, the travel switch comprises a contact arm located on the rear side of the locking pin, the locking pin is matched with the contact arm in a blocking mode when located at the unlocking position so that the travel switch can be in a closed state, and the locking pin is far away from the contact arm when located at the locking position so that the travel switch can be in an open state. The invention provides a safe locking device capable of locking mechanical equipment and stopping operation of the equipment at the same time.
