[0015] Further, one end of the electric push rod close to the pulling plate extends to the outer end of the round-hole plate. The surface of the cylindrical rod is slidably connected to the inner wall of the sliding hole block, and the end of the cylindrical rod extends to the outer end of the sliding hole block.

[0020] Further, a method for using a conveying trolley with variable tracks includes the following steps:

[0021] S1: Place the material inside the transport frame for storage. There is a toothed plate inside the transport frame, which can support the cylindrical material and prevent the cylindrical material from falling off when the transport frame transports it. The track-changing component pushes the transport frame to move on the top of the variable track;

[0022] S2: The linkage plate pushes the lifting frame to slide downward on the surface of the sliding plate through the round hole plate. When the lifting frame slides downward, it pushes the moving wheel to contact the top of the track through the connection with the power device 1. At this time, when the hydraulic rod continuously pushes the linkage plate downward, the track will support the linkage plate through the moving wheel. At this time, the hydraulic rod pulls the bearing frame upward through the support of the linkage plate;

[0023] S3: When the pulling plate moves, it pushes the I-shaped frame to slide inside the through-hole plate and pushes the through-hole plate to rotate on the surface of the central rod. When the through-hole plate moves, it pushes the cylindrical rod upward through the sliding hole block, and the cylindrical rod pushes the bearing frame upward through the lifting frame;

[0024] S4: The hinge rod pushes the semi-circular frame to deform and pushes the positioning rod to move towards the center of the bottom of the transport frame. When the through-hole plate moves and pushes the bearing frame and the transport frame to move closer to each other through the contact plate, it moves synchronously with the semi-circular frame through the moving force-bearing rod.

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

[0026] In the present invention, the material is placed inside the transport frame for storage. There is a toothed plate inside the transport frame, which can support the cylindrical material and prevent the cylindrical material from falling off when the transport frame transports it. The track-changing component pushes the transport frame to move on the top of the variable track. When the track-changing component moves to the corresponding track and then moves downward and contacts the top of the track, the track-changing component will separate from the top of the variable track to complete the track-changing operation. The lifting component can push the track-changing component to separate from the top of the variable track during the operation, improving the stability of the track-changing component during track-changing. After the track-changing component completes the track-changing, it will squeeze the stabilizing component to deform, and the stabilizing component is used to support the track-changing component, improving the stability of the track-changing component after track-changing.

[0027] After placing the material inside the transport rack, the present invention starts the second power device to drive the track-changing wheel to move on the top of the track-changing track. When the moving wheel corresponds to the track, the hydraulic rod is started to push the linkage plate downward. The linkage plate pushes the lifting frame to slide downward on the surface of the sliding plate through the round hole plate. When the lifting frame slides downward, it pushes the moving wheel to contact the top of the track through the connection with the first power device by the support plate. At this time, when the hydraulic rod continuously pushes the linkage plate downward, the track will support the linkage plate through the moving wheel. At this time, the hydraulic rod pulls the bearing frame upward through the support of the linkage plate, and the bearing frame pushes the track-changing wheel to separate from the top of the track-changing track to complete the track-changing operation, improving the convenience of the track-changing operation of the transport rack.

[0028] When the hydraulic rod pushes the linkage plate downward and makes the moving wheel contact the top of the track, the present invention starts the electric push rod to pull the pull plate to move. When the pull plate moves, it pushes the I-shaped frame to slide inside the through-hole plate and pushes the through-hole plate to rotate on the surface of the central rod. When the through-hole plate moves, it pushes the cylindrical rod upward through the sliding hole block. The cylindrical rod pushes the bearing frame upward through the lifting frame, improving the stability of the bearing frame during the track-changing operation.

[0029] The articulated rod of the present invention pushes the semi-circular frame to deform and pushes the positioning rod to move towards the center of the bottom of the transport rack. When the through-hole plate moves and pushes the bearing frame and the transport rack to move closer to each other through the contact plate, it moves synchronously with the semi-circular frame through the moving force-bearing rod. The semi-circular frame can be supported and fixed by the extrusion of the through-hole plate on the contact plate, and the semi-circular frame is used to improve the stability of the bearing frame and the transport rack after the track-changing is completed.

[0030] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

When the moving wheel 17 corresponds to the track 2, the hydraulic rod 22 is started to push the linkage plate 15 downward. The linkage plate 15 pushes the lifting frame 18 to slide downward on the surface of the skateboard 12 through the round hole plate 11. When the lifting frame 18 slides downward, it pushes the moving wheel 17 to contact the top of the track 2 through the connection with the power device one 20 by the support plate 19. At this time, when the hydraulic rod 22 continuously pushes the linkage plate 15 downward, the track 2 will support the linkage plate 15 through the moving wheel 17.

In the present invention, when the hydraulic rod 22 pushes the linkage plate 15 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 central rod 34. When the through-hole plate 32 moves, it pushes the cylindrical rod 36 upward through the sliding hole block 31. The cylindrical rod 36 pushes the bearing frame 10 upward through the landing gear 35, improving the stability of the bearing frame 10 during the variable track operation. The surface of the cylindrical rod 36 is slidably connected with the inner wall of the sliding hole block 31, and the end of the cylindrical rod 36 extends to the outer end of the sliding hole block 31.

[0057] A method for using a variable-track conveying trolley includes the following steps:

[0058] S1: Place the material inside the transport frame 3 for storage. A toothed plate 4 is provided inside the transport frame 3, and the toothed plate 4 can support the cylindrical material to prevent the cylindrical material from falling off when the transport frame 3 transports it. The track-changing member 5 pushes the transport frame 3 to move on the top of the variable track 1;

[0059] S2: The linkage plate 15 pushes the lifting frame 18 to slide downward on the surface of the sliding plate 12 through the circular hole plate 11. When the lifting frame 18 slides downward, it pushes the moving wheel 17 to contact the top of the track 2 through the connection with the power device 20 of the support plate 19. At this time, when the hydraulic rod 22 continuously pushes the linkage plate 15 downward, the track 2 will support the linkage plate 15 through the moving wheel 17. At this time, the hydraulic rod 22 pulls the carrier 10 upward through the support of the linkage plate 15;

[0060] S3: 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 central rod 34.

[0061] S4: The articulated rod 42 pushes the semi-circular frame 40 to deform, and pushes the positioning rod 41 to move towards the bottom center of the transport frame 3. When the through-hole plate 32 moves and pushes the bearing frame 10 and the transport frame 3 to move closer to each other through the contact plate 44, it moves synchronously with the semi-circular frame 40 through the moving force-bearing rod 43.

[0062] During use, the material is placed inside the transport rack 3 for storage. Inside the transport rack 3, there is a toothed plate 4 which can support the cylindrical material, preventing the cylindrical material from falling off when the transport rack 3 transports it. 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 separates 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, improving the stability of the track-changing component 5 during track-changing. After the track-changing component 5 completes the track-changing, it squeezes the stabilizing component 7 to deform, and the stabilizing component 7 is used to support the track-changing component 5, improving the stability of the track-changing component 5 after track-changing. After the material is placed inside the transport rack 3, the power device two 14 is started to drive the track-changing wheel 16 to move on the top of the variable track 1.

When the lifting frame 18 slides downward, it pushes the moving wheel 17 to contact the top of the track 2 through the connection with the power device one 20 by the support plate 19. At this time, when the hydraulic rod 22 continuously pushes the linkage plate 15 downward, the track 2 supports the linkage plate 15 through the moving wheel 17. At this time, the hydraulic rod 22 pulls the bearing frame 10 upward through the support of the linkage plate 15. The bearing frame 10 pushes the track-changing wheel 16 to separate from the top of the variable track 1 to complete the track-changing operation, improving the convenience of the track-changing operation of the transport rack 3. When the hydraulic rod 22 pushes the linkage plate 15 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 central rod 34. When the through-hole plate 32 moves, it pushes the cylindrical rod 36 upward through the sliding hole block 31. The cylindrical rod 36 pushes the bearing frame 10 upward through the lifting frame 35, improving the stability of the bearing frame 10 during the track-changing operation. When the bearing frame 10 and the transport rack 3 move closer to each other, the semi-circular frame 40 is pushed to deform through the hinge rod 42, and the positioning rod 41 is pushed to move towards the center of the bottom of the transport rack 3. When the through-hole plate 32 moves, it pushes the force-bearing rod 43 to move synchronously with the semi-circular frame 40 through the contact plate 44. The extrusion of the through-hole plate 32 on the contact plate 44 can support and fix the semi-circular frame 40, and the semi-circular frame 40 is used to improve the stability of the bearing frame 10 and the transport rack 3 after the track-changing is completed.
