[0006] A vertical warehouse forklift includes a base, a sliding plate, and a moving plate:

[0007] The sliding plate can slide on the base; the moving plate is slidably arranged on the sliding plate, and the sliding direction is the same as the sliding direction between the sliding plate and the base;

[0008] Three coaxial and spaced rotating shafts are rotated on the base. The three rotating shafts are installed in the middle position of the base. A main gear is installed on the middle rotating shaft, and driven gears meshing with the main gear are installed on both of the two rotating shafts on both sides. The outer diameter of the driven gear is larger than the outer diameter of the main gear. A motor is provided below the base and corresponding to the position of the middle rotating shaft. The output end of the motor is connected to one end of the rotating shaft extending out of the base;

[0009] A rack meshing with the driven gear is provided on one side below the sliding plate. Through the meshing of the rack and the driven gear, the sliding plate can be driven to move;

[0010] Synchronous belts are installed at both ends of the sliding plate. A connecting block is provided at the end of the moving plate in the sliding direction, and the connecting block is installed on the outer surface of one end of the synchronous belt.

[0011] Further, the sliding plate includes two side plates and a main board located between the side plates. The rack is installed below the main board, the synchronous belts are installed on both sides of the main board, and the main board is installed at the central position of the side plates.

[0012] Furthermore, slide rails are installed on both sides of the base. The slide rails are arranged oppositely, and the side plates are respectively connected to the adjacent slide rails in a matching manner.

[0013] Furthermore, mounting openings for conveniently installing synchronous belt pulleys and motors are provided at the four corners of the main board, and the rack is installed at the position between the synchronous belts.
