[0026] As Figure 1 shown, the tank body conveying device of this embodiment includes: a frame 10, a conveying mechanism 20, an adjusting structure 30, a measuring structure, and a display structure. The conveying mechanism 20 is arranged on the frame 10. The conveying mechanism 20 includes a first conveying chain 21 and a second conveying chain 22 arranged at intervals. The first conveying chain 21 and the second conveying chain 22 can clamp the workpiece to be conveyed. The side of the first conveying chain 21 close to the second conveying chain 22 and the side of the second conveying chain 22 close to the first conveying chain 21 are both movably arranged along a preset direction. The adjusting structure 30 is arranged on the frame 10 and is adjustably matched with both the first conveying chain 21 and the second conveying chain 22 to make the first conveying chain 21 and the second conveying chain 22 approach or move away from each other.

The display structure is signal-connected to the measuring structure, and the display structure is used to display the measurement result of the measuring structure.

[0027] Applying the technical solution of this embodiment, the tank body conveying device includes a frame 10, a conveying mechanism 20, an adjusting structure 30, a measuring structure and a display structure. The conveying mechanism 20 and the adjusting structure 30 are both arranged on the frame 10. The conveying mechanism 20 can clamp the workpiece to be conveyed. The conveying mechanism 20 includes a first conveying chain 21 and a second conveying chain 22. The first conveying chain 21 and the second conveying chain 22 are arranged at intervals. The first conveying chain 21 and the second conveying chain 22 can clamp the workpiece to be conveyed. One side of the first conveying chain 21 close to the second conveying chain 22 and one side of the second conveying chain 22 close to the first conveying chain 21 are both movably arranged along a preset direction. The adjusting structure 30 is adjustably matched with both the first conveying chain 21 and the second conveying chain 22 so that the first conveying chain 21 and the second conveying chain 22 approach or separate from each other. The measuring structure is used to measure the distance between the first conveying chain 21 and the second conveying chain 22. The display structure is signal-connected to the measuring structure and is used to display the measurement result of the measuring structure. Through the above settings, the frame 10 can support the conveying mechanism 20 and the adjusting structure 30. The conveying mechanism 20 can clamp the workpiece to be conveyed and realize the conveying of the workpiece to be conveyed. One side of the first conveying chain 21 close to the second conveying chain 22 and one side of the second conveying chain 22 close to the first conveying chain 21 are both movably arranged along a preset direction, so that the first conveying chain 21 and the second conveying chain 22 can clamp the workpiece to be conveyed and move simultaneously. The adjusting structure 30 can adjust the distance between the first conveying chain 21 and the second conveying chain 22, so that the first conveying chain 21 and the second conveying chain 22 can clamp workpieces to be conveyed with different sizes, that is, the conveying mechanism 20 can clamp workpieces to be conveyed with different sizes, and further improve the versatility of the tank body conveying device. When adjusting the distance between the first conveying chain 21 and the second conveying chain 22, the measuring structure can measure the distance between the first conveying chain 21 and the second conveying chain 22, and the display structure can display the measurement result of the measuring structure, which is convenient for accurately adjusting the distance between the first conveying chain 21 and the second conveying chain 22 according to the measurement result of the measuring structure. After the distance between the first conveying chain 21 and the second conveying chain 22 is adjusted, the first conveying chain 21 and the second conveying chain 22 can clamp the workpiece to be conveyed more effectively, avoiding the first conveying chain 21 and the second conveying chain 22 applying too much pressure on the workpiece to be conveyed, causing damage to the workpiece to be conveyed, or the first conveying chain 21 and the second conveying chain 22 applying too little pressure on the workpiece to be conveyed, and the workpiece to be conveyed separating from the first conveying chain 21 and the second conveying chain 22. Therefore, the technical solution of this embodiment effectively solves the problem of low accuracy in adjusting the distance between the first conveyor belt and the second conveyor belt in the related art.

[0028] It should be noted that in this embodiment, the item to be conveyed refers to the tank body. The preset direction refers to the advancing direction of the tank body. The difference between the maximum value and the minimum value of the distance between the first conveying chain 21 and the second conveying chain 22 is between 10 cm and 30 cm. Specifically, it can be 10 cm, 15 cm, 20 cm, 25 cm, or 30 cm. In this embodiment, the difference between the maximum value and the minimum value of the distance between the first conveying chain 21 and the second conveying chain 22 is 20 cm.

[0029] The signal connection between the display structure and the measurement structure means that the display structure and the measurement structure can be connected by wire to realize the transmission of the measurement signal of the measurement structure. Of course, the signal transmission between the display structure and the measurement structure can also be transmitted by wireless signals.

[0030] As Figure 1 shown, in this embodiment, the display structure includes a display screen. Through the display screen, the distance between the first conveying chain 21 and the second conveying chain 22 can be displayed, which is convenient for adjusting the distance between the first conveying chain 21 and the second conveying chain 22 through the adjusting structure 30.

[0031] As Figure 2 shown, in this embodiment, the adjusting structure 30 includes an operation part 31 and a driving screw 32 connected to the operation part 31. The driving screw 32 is rotatably arranged on the frame 10, and the driving screw 32 is in adjusting cooperation with both the first conveying chain 21 and the second conveying chain 22. The operation part 31 can drive the driving screw 32 to rotate, and then the driving screw 32 can drive the first conveying chain 21 and the second conveying chain 22 to move, so that the first conveying chain 21 and the second conveying chain 22 approach or move away from each other, that is, the distance between the first conveying chain 21 and the second conveying chain 22 is adjusted.

[0032] As Figure 2 shown, in this embodiment, the conveying mechanism 20 further includes a first support structure 23 and a second support structure 24. The first conveying chain 21 is arranged on the first support structure 23, and the second conveying chain 22 is arranged on the second support structure 24. The driving screw 32 is in threaded cooperation with the first support structure 23 and the second support structure 24. The driving screw 32 can drive the first support structure 23 and the second support structure 24 to move. The movement of the first support structure 23 can drive the first conveying chain 21 to move, and the movement of the second support structure 24 can drive the second conveying chain 22 to move. Therefore, when the driving screw 32 moves, it can drive the first conveying chain 21 and the second conveying chain 22 to move, realizing the adjustment of the distance between the first conveying chain 21 and the second conveying chain 22.

[0033] As Figure 2As shown, in this embodiment, the operating part 31 includes an operating handwheel 311. Through the above arrangement, when the operating handwheel 311 is rotated, the operating handwheel 311 can drive the driving screw 32 to rotate.

[0034] As Figure 2 shown, in this embodiment, the first support structure 23 includes a first connection block 2305, the driving screw 32 is disposed in the first connection block 2305, the second support structure 24 includes a second connection block 241, and the driving screw 32 is disposed in the second connection block 241. When the driving screw 32 rotates, it can drive the first connection block 2305 and the second connection block 241 to move, that is, it can make the first connection block 2305 and the second connection block 241 move relatively closer or relatively farther away, so that the first connection block 2305 can drive the first conveying chain 21 to move, and the second connection block 241 can drive the second conveying chain 22 to move, so as to realize the relative approach or relative separation of the first conveying chain 21 and the second conveying chain 22.

[0035] As Figures 1 to 3 shown, in this embodiment, the tank conveying device further includes a guiding structure 40 extending in the direction from the first support structure 23 to the second support structure 24. The guiding structure 40 includes a first guiding member 41 disposed between the frame 10 and the first support structure 23 and a second guiding member 42 disposed between the frame 10 and the second support structure 24. The first guiding member 41 makes the movement of the first support structure 23 relative to the frame 10 smoother. The second guiding member 42 makes the movement of the second support structure relative to the frame 10 smoother.

[0036] As Figure 2 shown, in this embodiment, the first guiding member 41 includes a guiding rod 411 and a guiding block 412. The guiding rod 411 is disposed on the frame 10, the guiding rod 411 is disposed in the guiding block 412, and the guiding block 412 is disposed on the first support structure 23. When the first support structure 23 moves, it can drive the guiding block 412 to move relative to the guiding rod 411, and the guiding block 412 is disposed on the first support structure 23, so that the first support structure 23 can move smoothly relative to the frame 10.

[0037] It should be noted that the structure of the second guiding member 42 is the same as that of the first guiding member 41. The guiding rod in the second guiding member 42 and the guiding rod in the first guiding member 41 are of an integral structure. Of course, in other embodiments, the guiding rod in the second guiding member 42 and the guiding rod in the first guiding member 41 can be separately provided.

[0038] As Figure 2As shown in the figure, in this embodiment, the first support structure 23 further includes a support frame 231 and a connection plate 232. The support frame 231 and the first connection block 2305 are spaced apart. The guide block 412 is arranged on the support frame 231, and the connection plate 232 is connected between the support frame 231 and the first connection block 2305. The support frame 231 can support the first conveyor chain 21 and can also drive the first conveyor chain 21 to move. The connection plate 232 can connect the support frame 231 and the first connection block 2305, so that when the driving screw 32 drives the first connection block to move, the first connection block 2305 can drive the support frame 231 to move through the connection plate 232.

[0039] As Figure 2 and Figure 3 shown in the figure, in this embodiment, the support frame 231 includes a support plate 2311 and a support frame 2312 arranged above the support plate 2311. The support plate 2311 extends along the direction from the first conveyor chain 21 to the second conveyor chain 22. The guide block 412 is arranged on the support plate 2311, and a part of the structure of the first conveyor chain 21 is arranged in the support frame 2312 and connected to the support frame 2312. The support plate 2311 can support the support frame 2312, and the support frame 2312 can support the first conveyor chain 21. When the support plate 2311 moves, it can drive the support frame 2312 to move. When the support plate 2311 moves, it can drive the guide block 412 to move, and then the guide block 412 can move relative to the guide rod 411.

[0040] It should be noted that the structure of the second support structure 24 is the same as that of the first support structure 23.

[0041] As Figure 3 and Figure 4 shown in the figure, in this embodiment, the conveying mechanism 20 further includes a driving member and a plurality of flexible clamping members 25. The driving member drives the first conveyor chain 21 to move, and the plurality of flexible clamping members 25 are spaced apart and arranged on the outer surface of the first conveyor chain 21. The driving member can drive the first conveyor chain 21 to move, and then the first conveyor chain 21 can drive the plurality of flexible clamping members 25 to move. The plurality of flexible clamping members 25 can jointly clamp the workpiece to be conveyed with the second conveyor chain 22 and drive the workpiece to be conveyed to move.

[0042] As Figure 4As shown, the conveying mechanism 20 further includes a connecting pin. The flexible clamping member 25 includes a mounting plate, a connecting head, and a support plate connected between the mounting plate and the connecting head. A connecting column is provided on the support plate. A plurality of grooves are provided on the first side of the mounting plate, and a plurality of protrusions are provided on the second side of the mounting plate. For any two adjacent flexible clamping members, one is a first flexible clamping member and the other is a second flexible clamping member. The plurality of protrusions of the first flexible clamping member are respectively inserted into the plurality of grooves of the second flexible clamping member, and one protrusion is inserted into each groove. The connecting head of the first flexible clamping member is connected to the support plate of the second flexible clamping member, and the connecting pin connects the connecting column of the support plate of the second flexible clamping member and the connecting head of the first flexible clamping member. The first flexible clamping member and the second flexible clamping member can swing around an axis perpendicular to the axis of the connecting pin, and can also swing around the axis of the connecting pin.

[0043] The driving member includes a driving motor. The driving motor is installed at one end of the conveying mechanism 20 close to the ground, which is convenient for maintenance. When the distance between the first conveying chain 21 and the second conveying chain 22 needs to be adjusted, rotate the operating handwheel 311, and the value on the display screen changes. The conveying mechanism 20 and the adjusting structure 30 can move on the frame 10, which is convenient for the tank body conveying device to adapt to different workpieces to be conveyed. The flexible clamping member 25 can avoid causing slight scratches to the workpiece to be conveyed.

[0044] Through the tank body conveying device of this embodiment, the workpiece to be conveyed can be conveyed from a higher position to a lower position.
