When the raw materials of chemical products are hoisted and transported, the hook at the bottom of the rotating plate is used to hoist the heavier raw materials of chemical products. After the raw materials are transported to the specified position, the servo motor on the top of the fixed plate drives the rotating plate to drive the raw materials at the bottom to rotate, so that the discharge port of the container storing the raw materials is accurately aligned with the processing equipment, reducing the workload of manual adjustment, preventing the problem of raw material shaking caused by manual adjustment, and allowing the chemical raw materials to be accurately put into the processing equipment for chemical product processing, thereby improving the processing efficiency of chemical products.

When the raw materials of chemical products are hoisted and transported, the driving motor on the top of the trolley carrier plate 106 is decelerated by the reducer, so that the gear on the side end of the reducer drives the storage rod 107 to rotate, so that the wire traction rope 108 wound on the storage rod 107 is retracted and released, and one end of the wire traction rope 108 is installed on the pulley on the bottom side of the trolley carrier plate 106, so that the wire traction rope 108 can adjust the height of the hoisted chemical product raw materials.

When the raw materials of chemical products are hoisted and transported, the fixed frame 3 drives the detection outer plate 301 and the detection inner plate 303 to be on the outer side of the wire traction rope 108. When the wire traction rope 108 slides on the inner side of the detection inner plate 303, the positioning plate 305 is driven to move under the action of the spring, so that the positioning plate 305 drives the guide rod 3 The inner end of 04 passes through the opening on the outside of the detection inner plate 303 and is inserted on the outside of the wire traction rope 108.
