AI Technical Summary
Technical Problem
Traditional cranes pose safety hazards when transporting waste catalyst containers, such as the container not being securely fixed, slipping during lifting, and the risk of the platform rapidly falling due to chain breakage.
Method used
A lifting device was designed, which uses a self-locking mechanism with a spring and a pin for double locking. Combined with a hydraulic cylinder and chain main drive, and with the following of a steel wire rope, it provides physical interception when the chain breaks to prevent falling.
Benefits of technology
This improved the safety of the waste catalyst tank dismantling process, prevented slippage and falling accidents, and ensured the stability and safety of the platform.

Abstract
The application discloses a lifting device for disassembling waste catalyst treatment boxes, which comprises a lifting mechanism and a disassembling workshop, wherein the lifting mechanism comprises two vertical plates, a platform and hydraulic cylinders, the platform is provided with two slide rails, a trolley is parked on the two slide rails, the platform is provided with self-locking mechanisms corresponding to two sides of the trolley, each self-locking mechanism comprises a supporting table and a bolt, each vertical plate is installed with a horizontal plate, the bottom of each horizontal plate is connected with a hydraulic cylinder, the two ends of the bottom of each horizontal plate are respectively installed with a fixed pulley, a steel wire rope is wound around each fixed pulley, the bolt in the self-locking structure is automatically inserted into the insertion hole of the trolley, and a baffle is used for limiting and fixing the trolley body, so that double self-locking is realized, and the trolley loaded with the box is prevented from sliding when the platform is lifted, thereby avoiding safety accidents; in the process that the platform is lifted by the main drive of the hydraulic cylinders and chains, the steel wire rope follows the movement; when the chain is broken, the steel wire rope is tensioned to bear the load of the platform, the platform is suspended, and safety accidents caused by the broken chain and the descending platform are avoided.
