[0014] To ensure the stability of the cage 15 during lifting, multiple first sleeves 21 corresponding to the second wire rope 17 are evenly fixed on the cage 15. The second wire rope 17 passes through the first sleeves 21 from top to bottom. Multiple second sleeves 22 corresponding to the third wire rope 18 are evenly fixed on the cage 15. The third wire rope 18 passes through the second sleeves 22 from top to bottom.

[0015] The flatbed cart 3 is an electric flatbed cart, and protective railings are fixed on the flatbed cart 3.

[0016] A control box 23 is installed inside the chamber 1.

[0017] To facilitate the loading and unloading of materials onto the flatbed cart 3, a crane 24 is installed inside the chamber 1, and the crane 24 is located on the left side of the support platform 4.

[0018] In use, when materials need to be transported into the shaft 2, the crane 24 is started, and the crane 24 places the materials on the loading flatcar 3. The guardrails prevent the materials from falling off the loading flatcar 3. The loading flatcar 3 moves the materials to the right along the track 6 of the chamber 1 onto the track 6 of the beam frame 5. When only the lifting device 16 is needed, the cage 15 is at the top, and the second winch 10 is started. The second winch 10 simultaneously releases or retracts the second wire rope 17 and the third wire rope. 18. The other end of the second wire rope 17 is fixed to the front side of the pulley frame 8, and the other end of the third wire rope 18 is fixed to the rear side of the pulley frame 8.

Then, the first winch 9 and the second winch 10 are started simultaneously. The first winch 9 and the second winch 10 operate synchronously. The first winch 9 releases or retracts the first wire rope 11. The first wire rope 11 controls the lifting and lowering of cage 15 via the first pulley block 12. When the cage 15 and the lifting device 16 move synchronously up and down, the first winch 9 and the second winch 10 are closed at the same time when the cage 15 moves to the position of the loading flatcar 3. The cage door of the cage 15 is opened, and the material on the loading flatcar 3 can be loaded into the cage 15. After loading is completed, the cage door of the cage 15 is closed, and the first winch 9 and the second winch 10 are started at the same time. The cage 15 and the lifting device 16 can be lifted and transported in the vertical shaft 2. Under the action of the first sleeve 21 and the second sleeve 22, the overall stability of the cage 15 is further guaranteed, making it safe and reliable. When both the lifting device 16 and the cage 15 are in operation, the second winch 10 is started first. The second winch 10 controls the lifting device 16 to rise and fall. When the lifting device 16 lifts the material to a suitable position inside the shaft 2, the second winch 10 is turned off and the first winch 9 is started. The first winch 9 controls the cage 15 to move downward to the loading flatcar 3. Then the remaining material is loaded into the cage 15. At the same time, the first winch 9 and the second winch 10 are started. The lifting device 16 and the cage 15 simultaneously transport the material down the shaft 2.
