[0031] A quick loading and unloading system comprises the above-mentioned loading and unloading device.

[0032] When the present invention is used, one end of the bottom plate 5 faces the loading area, and the other end faces the unloading area. The staff can stack the goods into the "V" area formed by the first rotating plate 7 and the loading and unloading block 9, and then start the second servo motor 30 to make the second rotating shaft 35 (attached) Figure 4The second rotating shaft 35 rotates counterclockwise, and the second rotating shaft 35 drives the disc 31 and the push rod 41 to rotate counterclockwise. During the counterclockwise rotation of the push rod 41 around the axis of the second rotating shaft 35, the push rod 41 will contact the inclined surface of the right-angled trapezoidal block 45. By setting the guide rod 48, the right-angled trapezoidal block 45 will move toward the direction close to the mounting block 40, and the spring 49 will be compressed. Finally, the push rod 41 will move from one side of the right-angled trapezoidal block 45 to the other side along the inclined surface of the right-angled trapezoidal block 45. In this process The mounting block 40 will not move, and the counterclockwise rotation of the second rotating shaft 35 will drive the inner ring of the first one-way bearing 44 to rotate counterclockwise. At this time, the inner ring and the outer ring of the first one-way bearing 44 are locked, and the outer ring of the first one-way bearing 44 and the second gear 33 rotate accordingly, thereby enabling the first gear 27 and the steering cylinder 3 to rotate. When the steering cylinder 3 rotates, the bottom plate 5 can be rotated by setting two adjusting rods 22, so that the stacked goods are rotated to a certain angle, so that the goods rotate toward the unloading area;

[0033] Then, the first servo motor 15 is started to rotate the first rotating shaft 17 and the turntable 20. By setting the unloading frame 18 and the moving rod 19, the unloading frame 18 can be moved left and right. By setting the first connecting rod 13, the two first loading and unloading plugs 12 slide left and rear in the two first inner chambers 14 respectively, so that the incompressible fluid in the one loading and unloading cylinder 4 is sucked into the one first inner chamber 14, so that the one second loading and unloading plug 21 and the one loading and unloading rod 11 move downward, and the gravity of the loading and unloading goods causes the one rotating plate 7 to deflect downward and finally be flush with the inclined surface of the loading and unloading block 9. At this time, the goods will slide down along the surface of the loading and unloading block 9 and the one rotating plate 7 to realize unloading, or the staff can push the goods down to realize unloading;

[0034] At the same time, the incompressible fluid in the first inner cavity 14 is squeezed into the other loading and unloading cylinder 4, so that the other second loading and unloading plug 21 and the other loading and unloading rod 11 move upward, and the other loading and unloading rod 11 moving upward can lift the other rotating plate 7 to deflect it upward, and finally the other rotating plate 7 and the loading and unloading block 9 form a "V" shape. At this time, the staff can stack the goods into the "V" area formed by the other rotating plate 7 and the loading and unloading block 9 to realize loading. In this way, the goods can be loaded and unloaded at the same time, which improves the work efficiency.

[0035] When it is necessary to load and unload goods at different heights, the second servo motor 30 is started to rotate the second shaft 35 (attached Figure 4The second gear 33 will not rotate, so that the steering cylinder 3 cannot rotate. However, the disc 31 and the push rod 41 will rotate clockwise, so that the push rod 41 will contact the plane section of the right-angled trapezoidal block 45, and make the right-angled trapezoidal block 45 and the mounting block 40 move a distance in the direction close to the outer cylinder 37. Then the push rod 41 will separate from the right-angled trapezoidal block 45 and no longer contact. In this way, the telescopic rod 43 will extend during the movement of the mounting block 40 in the direction close to the outer cylinder 37, and the tension spring 42 will be extended. At the same time, the displacement block 50 will slide in the spiral groove 47, so that the outer cylinder 37 and the outer ring of the second one-way bearing 46 will rotate several times in one direction. At this time, the outer ring and the inner ring of the second one-way bearing 46 are locked, and the reciprocating screw rod 36 will rotate several times in one direction, so that the displacement block 50 The movable plate 24 moves in a direction approaching or away from the adjusting box 34 by setting the second connecting rod 25 and the second adjusting plug 26, so that the incompressible fluid in the adjusting box 34 can be squeezed into the steering cylinder 3 through the second mounting tube 28 and the third mounting tube 32, or the incompressible fluid below the first adjusting plug 23 in the steering cylinder 3 is sucked into the adjusting box 34 through the second mounting tube 28 and the third mounting tube 32, so that the first adjusting plug 23 moves upward or downward. By setting the adjusting rod 22, the bottom plate 5 can be moved upward or downward, so that the height of different loading and unloading goods can be adjusted. When the push rod 41 is separated from the right-angle trapezoidal block 45 and no longer contacts, the tension generated by the elongation of the tension spring 42 can make the mounting block 40 move away from the outer cylinder 37. At this time, the displacement block 50 will slide in the spiral groove 47, so that the outer cylinder 37 can rotate several times in the other direction. At this time, the outer ring and the inner ring of the second one-way bearing 46 will idle, and the reciprocating screw 36 will not rotate.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
