The utility model relates to a double-pinhole safety locking mechanism applied to an elevator drive, which is characterized in that the double-pinhole safety locking mechanism is arranged at the side of a roller rotary table and comprises a locking bracket, an auxiliary bracket and locking pins; the locking bracket is fixedly arranged on a platform; the auxiliary bracket is fixedly arranged on the locking bracket; a passage for ensuring the roller rotary table to rotate is reserved between the auxiliary bracket and the locking bracket; two pinholes for inserting the locking pins are respectively arranged at the positions in the locking bracket and the auxiliary bracket, which are opposite to the edge of the roller rotary table; the minimum distance between the edges of the two pinholes is greater than the width of each rotary table tooth of the roller rotary table; and the maximum distance between the edges of the two pinholes is less than the width of a rotary table groove of the roller rotary table. The double-pinhole safety locking mechanism disclosed by the utility model has a simple and ingenious structure; by reasonably arranging the positions of the two pinholes in the locking bracket and the auxiliary bracket, the elevator drive can be locked under any condition; and the double-pinhole safety locking mechanism has high safety.
