[0025] The present invention has the following beneficial effects:

[0026] The present invention places materials inside the transport rack for storage, and a toothed plate is arranged inside the transport rack, which can support cylindrical materials to prevent the transport rack from falling off when transporting the cylindrical materials. The track-changing component pushes the transport rack to move on the top of the changing track, and when the track-changing component moves to the corresponding track, it moves downward and contacts with the top of the track, at which time the track-changing component will be separated from the top of the changing track to complete the track-changing operation. The lifting and lowering component can push the track-changing component to separate from the top of the changing track during operation, thereby improving the stability of the track-changing component during track-changing. After completing the track-changing, the track-changing component will squeeze the stabilizing component to generate deformation, and the stabilizing component is used to support the track-changing component, thereby improving the stability of the track-changing component after the track-changing.

[0027] After the material is placed inside the transport rack, the present invention starts power device 2 to drive the track-changing wheel to move on the top of the variable track. When the moving wheel corresponds to the track, the hydraulic rod is started to push the linkage plate to move downward. The linkage plate pushes the lifting frame to slide downward on the surface of the slide plate through the circular hole plate. When the lifting frame slides downward, the connection between the support plate and power device 1 pushes the moving wheel to contact with the top of the track. At this time, when the hydraulic rod continues to push the linkage plate to move downward, the track will support the linkage plate through the moving wheel. At this time, the hydraulic rod pulls the load frame upward through the support of the linkage plate, and the load frame pushes the track-changing wheel to separate from the top of the variable track to complete the track changing operation, thereby improving the convenience of the track changing operation of the transport rack.

[0028] When the hydraulic rod pushes the linkage plate to move downward and pushes the moving wheel to contact the top of the track, the electric push rod is started to pull the pull plate to move. When the pull plate moves, it pushes the I-frame to slide inside the through-hole plate and pushes the through-hole plate to rotate on the surface of the center rod. When the through-hole plate moves, it pushes the cylindrical rod to move upward through the sliding block. The cylindrical rod pushes the bearing frame to move upward through the landing gear, thereby improving the stability of the bearing frame during the track changing operation.

[0029] The hinged rod of the present invention pushes the semicircular frame to deform and pushes the positioning rod to move toward the bottom center of the transport frame. When the through-hole plate moves, it pushes the load-bearing frame and the transport frame to move closer to each other through the contact plate. The dynamic force-bearing rod moves synchronously with the semicircular frame. The semicircular frame can be supported and fixed by squeezing the contact plate by the through-hole plate. The semicircular frame is used to improve the stability of the load-bearing frame and the transport frame after the track change is completed.

The track-changing component 5 pushes the transport rack 3 to move on the top of the variable track 1. When the track-changing component 5 moves to the corresponding track 2, it moves downward and contacts the top of the track 2. At this time, the track-changing component 5 will separate from the top of the variable track 1 to complete the track-changing operation. The lifting and lowering component 6 can push the track-changing component 5 to separate from the top of the variable track 1 during operation, thereby improving the stability of the track-changing component 5 during track-changing. The track-changing component 5 completes the track-changing operation. After that, the stabilizing component 7 will be squeezed to produce deformation, and the stabilizing component 7 will be used to support the track changing component 5 to improve the stability of the track changing component 5 after the track changing.

The carrier 10 pushes the track-changing wheel 16 to separate from the top of the track 1 to complete the track-changing operation, thereby improving the convenience of the track-changing operation of the transport frame 3. When the hydraulic rod 22 pushes the linkage plate 15 to move downward and pushes the moving wheel 17 to contact the top of the track 2, the electric push rod 30 is started to pull the pull plate 38 to move. When the pull plate 38 moves, it pushes the I-shaped frame 37 to slide inside the through-hole plate 32, and pushes the through-hole plate 32 to rotate on the surface of the center rod 34. When the through-hole plate 32 moves, it passes through the sliding hole Block 31 pushes the cylindrical rod 36 to move upward, and the cylindrical rod 36 pushes the carrier 10 to move upward through the landing gear 35, thereby improving the stability of the carrier 10 during the track change operation. When the carrier 10 and the transport frame 3 move closer to each other, the semicircular frame 40 is pushed to deform through the hinged rod 42, and the positioning rod 41 is pushed to move toward the bottom center of the transport frame 3. When moving, the through-hole plate 32 pushes the force-bearing rod 43 and the semicircular frame 40 to move synchronously through the contact plate 44.
