The invention relates to an automatic lifting control device for a cage curtain of an auxiliary shaft cage. An existing cage curtain lifting device is slow in starting, large in energy consumption, prone to being damaged, high in cost and unsafe. Therefore, the automatic lifting control device for the cage curtain of the auxiliary shaft cage comprises the cage and the cage curtain, the cage is provided with a cage door, and a rolling shaft is arranged in the cage. A sliding rail is arranged on the outer side of the cage, and a gravity sliding block is arranged on the sliding rail. Air cylinders are arranged at the top and bottom of an auxiliary shaft respectively, and each air cylinder comprises a cylinder body and a piston rod. The air cylinders are reversely arranged, the tops of the cylinder bodies are fixed, and fish lips are formed in the lower ends of the piston rods. Fish lip pressing plates are hinged to the interiors of the fish lips, a supporting plate is arranged on one side of each fish lip, and a reversing steel channel is arranged at the lower end of each cylinder body. The piston rods stretch downwards, the fish lip pressing plates are kept horizontal, and the long ends of the fish lip pressing plates are pressed on the gravity sliding block. The cage curtain is driven by a main rolling rope to be rolled up, and when the piston rods retract, the fish lip pressing plates are changed to be vertically downward, and ascending and descending of the cage are not influenced. The automatic lifting control device is suitable for being used in various coal mine auxiliary shafts.
