DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1-Figure 6As shown, a loading and transporting device for loading and unloading goods comprises a base plate 1, two moving platforms 2 symmetrically distributed front and back are fixedly connected to the front and rear sides of the upper side of the base plate 1 near the left side, four rectangularly distributed first hydraulic push rods 3 are fixedly connected to the positions near the front and rear sides of the upper side of the base plate 1, two second hydraulic push rods 4 symmetrically distributed front and back are fixedly connected to the inner sides of the bosses on the front and rear sides of the lower side of the base plate 1, four rectangularly distributed universal wheels 5 are rotatably connected to the positions near the four corners of the lower side of the base plate 1, a transport mechanism 6 is slidably connected to the inner side of the moving platform 2, a cross plate mechanism 7 is fixedly connected to the right side of the transport mechanism 6, two limiting mechanisms symmetrically distributed front and back are fixedly connected to the positions near the right side of the front and rear sides of the transport mechanism 6, the right ends of the two second hydraulic push rods 4 are both rotatably connected to the third connecting rod 9, and the upper end of the third connecting rod 9 is rotatably connected to the lower side of the transport mechanism 6;

[0033] The transport mechanism 6 includes a first mechanism platform 61, and four rectangularly distributed rotating components 65 are rotatably connected to the positions near the left and right ends of the front and rear sides of the first mechanism platform 61, and the position between the rotating components 65 on the left side is rotatably connected to the second mechanism platform 62, and a first conveying platform 63 is movably installed on the inner side of the first mechanism platform 61, and a second conveying platform 64 is movably installed on the inner side of the second mechanism platform 62;

[0034] The horizontal plate mechanism 7 includes a first horizontal plate 71, and the front and rear sides of the first horizontal plate 71 are fixedly connected to the position between the right rotating components 65;

[0035] The limiting mechanism 8 includes a first connecting rod 81, the right end of which is fixedly connected to the front side of the right rotating component 65, and the front and rear sides of the first mechanism platform 61 are fixedly connected with an adjusting platform 82, and the left end of the first connecting rod 81 is threadedly connected with a second screw 83, and the second screw 83 is rotatably connected to a clamping block 84 on the side close to the first conveying platform 63, and the inner side of the clamping block 84 is slidably connected to the boss of the adjusting platform 82 away from the first conveying platform 63.

[0036] It should be noted that the first hydraulic push rod 3 can control its own length, so that when the first hydraulic push rod 3 is extended, the base plate 1 drives the universal wheel 5 to lift up, which is used to fix the whole. The second hydraulic push rod 4 can control its own length and thus push the lower end of the third connecting rod 9 to move. The upper part of the movable platform 2 contains a moving component, which is used to drive the transportation mechanism 6 to move right as a whole. The upper end of the third connecting rod 9 is rotatably connected to the downward movement of the first mechanism platform 61, so that when the third connecting rod 9 moves, the first mechanism platform 61 rotates around the left end. By screwing the second screw 83, the block 84 can squeeze the adjustment platform 82, so that the first connecting rod 81 is fixed to adjust the angle between the right rotating component 65 and the first mechanism platform 61.

[0037] like Figure 3 , Figure 4As shown, the rotating assembly 65 includes a rotating plate 651, and the side of the rotating plate 651 close to the first conveying platform 63 is rotatably connected to the front and rear sides of the first mechanism platform 61 near the left and right ends. The outer side of the rotating plate 651 is movably sleeved with a fixed sleeve 652, and the side of the fixed sleeve 652 close to the first conveying platform 63 is fixedly connected to the middle right position of the front and rear sides of the second mechanism platform 62 and the middle left position of the front and rear sides of the first cross plate 71. The side of the rotating plate 651 away from the first mechanism platform 61 is movably sleeved with a fixed seat 653 inside, and the side of the rotating plate 651 away from the first mechanism platform 61 is movably sleeved with a spring 654 inside, and the spring 654 is located on the inner side of the fixed seat 653. The side of the fixed sleeve 652 away from the second mechanism platform 62 is provided with two clamping holes 657 distributed on the left and right, and the outer side of the fixed seat 653 is movably sleeved on the inner side of the clamping hole 657.

[0038] It should be noted that when the fixed seat 653 is movably sleeved into the inner side of the clamping hole 657 away from the side of the first mechanism platform 61, the rotating plate 651 is on the inner side of the fixed sleeve 652, so that the rotating plate 651 is fixed, so that the second mechanism platform 62 and the first mechanism platform 61 and the first horizontal plate 71 and the first mechanism platform 61 cannot rotate a second time, the first horizontal plate 71 and the second mechanism platform 62 are moved to the upper side of the first mechanism platform 61, and the fixed seat 653 is pressed so that the fixed seat 653 is moved to the inner side of the clamping hole 657 close to the side of the first mechanism platform 61, so that the first mechanism platform 61 and the second mechanism platform 62 and the first mechanism platform 61 and the first horizontal plate 71 can rotate a second time.

[0039] like Figure 4 As shown, a plurality of annular limiting grooves 655 are provided on the inner side of the rotating plate 651 away from the first mechanism platform 61 . The limiting grooves 655 are L-shaped, and the outer protrusions of the fixing seat 653 are slidably connected to the inner side of the limiting grooves 655 .

[0040] It should be noted that the limiting groove 655 is used to fix the fixing seat 653 . The fixing seat 653 is pressed and then rotated, so that the fixing seat 653 is fixed, and the fixing seat 653 cannot be ejected by the spring 654 .

[0041] like Figure 4 As shown, a rotation groove 656 is formed on a side of the fixing seat 653 away from the second mechanism platform 62 .

[0042] It should be noted that the rotation groove 656 is used for an external person to use a tool to manipulate the fixing seat 653 , so as to facilitate the rotation of the fixing seat 653 .

[0043] like Figure 5 As shown, the second transverse plate 72 is slidably connected to the lower side of the first transverse plate 71 , and the first screw 73 is threadedly connected to the inner side of the protrusion on the lower side of the first transverse plate 71 close to the right side.

[0044] It should be noted that a first circular plate is provided on the first screw 73. Rotating the first screw 73 can timely fix the second transverse plate 72 by the first transverse plate 71 and the first circular plate, so that the second transverse plate 72 and the first transverse plate 71 cannot slide relative to each other, thereby controlling the total length between the first transverse plate 71 and the second transverse plate 72.

[0045] like Figure 6 As shown, a plurality of linearly distributed limiting holes 85 are provided on the inner side of the boss of the adjusting platform 82 away from the first mechanism platform 61 , and the plug posts of the clamping block 84 on the side close to the first mechanism platform 61 are movably sleeved on the inner side of the limiting holes 85 .

[0046] It should be noted that the limiting hole 85 is used to fix the clamping block 84 to prevent the friction between the clamping block 84 and the adjustment platform 82 from being too low, resulting in unstable fixation of the first transverse plate 71 .

[0047] like Figure 6 As shown, an indicating notch 86 is provided on a side of the adjustment platform 82 away from the first connecting rod 81 .

[0048] It should be noted that the indicator notch 86 is used to determine the distance that the block 84 moves on the adjustment platform 82 , and then to deduce the angle at which the first transverse plate 71 rotates relative to the first mechanism platform 61 .

[0049] like Figure 3 As shown, four rectangularly distributed second connecting rods 87 are rotatably connected to the upper sides of the front and rear sides of the first mechanism platform 61 , and the upper ends of the four second connecting rods 87 are all threadedly connected with third screws 88 .

[0050] It should be noted that, when the second mechanism platform 62 and the first horizontal plate 71 are rotated for the second time and stacked on the first mechanism platform 61, the third screw 88 approaches the clamping hole 657 on the fixing sleeve 652 which was originally away from the side of the first mechanism platform 61, and the third screw 88 is rotated. The third screw 88 is provided with a second circular plate, so that the second circular plate is movably sleeved into the inner side of the clamping hole 657, so that the second mechanism platform 62 and the first horizontal plate 71 are fixed.

[0051] The working principle of the present invention is as follows: first, the first hydraulic push rod 3 can control its own length, so that when the first hydraulic push rod 3 is extended, the base plate 1 drives the universal wheel 5 to lift up, which is used to fix the whole body; the second hydraulic push rod 4 can control its own length and drive the lower end of the third connecting rod 9 to move; the upper part of the moving platform 2 contains a moving component, which is used to drive the transportation mechanism 6 to move right as a whole; the upper end of the third connecting rod 9 is rotatably connected to the lower movement of the first mechanism platform 61, so that when the third connecting rod 9 moves, the first mechanism platform 61 rotates around the left end, and the transportation mechanism 6 is driven to move right as a whole through the moving component on the moving platform 2; the first hydraulic push rod 3 drives the first mechanism platform 61 to rotate and lift up, so that the second mechanism platform 62, the first mechanism platform 61 and the first cross plate 7 1 forms a Z-shape, so that the goods at a high place are moved to a low place. Secondly, a first circular plate is provided on the first screw 73. By rotating the first screw 73, the first horizontal plate 71 and the first circular plate can be fixed to the second horizontal plate 72 in time, so that the second horizontal plate 72 and the first horizontal plate 71 cannot slide relative to each other, thereby controlling the total length between the first horizontal plate 71 and the second horizontal plate 72. The first horizontal plate 71 and the second horizontal plate 72 are provided to make up the gap between the first conveying platform 63 and the high unloading position to prevent the goods from falling from the gap. Then, by screwing the second screw 83, the block 84 can be pressed against the adjusting platform 82, so that the first connecting rod 81 is fixed to adjust the clamping between the right rotating component 65 and the first mechanism platform 61. The indicating notch 86 is used to determine the distance that the block 84 moves on the adjustment platform 82, and then derive the rotation angle of the first cross plate 71 relative to the first mechanism platform 61. The limiting hole 85 is used to fix the block 84 to prevent the friction between the block 84 and the adjustment platform 82 from being too low, resulting in unstable fixation of the first cross plate 71. By rotating the second screw 83, the lower end of the first connecting rod 81 can be quickly fixed, so that the state of the first cross plate 71 is fixed, so that the first cross plate 71 can always be in a horizontal state, preventing the first cross plate 71 from collapsing. Finally, when the second mechanism platform 62 and the first cross plate 71 are rotated and stacked on the first mechanism platform 61 for the second time, the third screw 88 is close to the side of the fixing sleeve 652 that was originally away from the first mechanism platform 61 The third screw 88 is rotated. The third screw 88 is provided with a second circular plate, so that the second circular plate is movably sleeved into the inner side of the clamping hole 657, so that the second mechanism platform 62 and the first horizontal plate 71 are fixed. When the fixing seat 653 is movably sleeved into the inner side of the clamping hole 657 away from the side of the first mechanism platform 61, the rotating plate 651 is located inside the fixing sleeve 652, so that the rotating plate 651 is fixed, so that the second mechanism platform 62 and the first mechanism platform 61 and the first horizontal plate 71 and the first mechanism platform 61 cannot rotate twice. The first horizontal plate 71 and the second mechanism platform 62 are moved to the upper side of the first mechanism platform 61, and the fixing seat 653 is pressed so that the fixing seat 653 is moved to the inner side of the clamping hole 657 close to the side of the first mechanism platform 61.The first mechanism platform 61 and the second mechanism platform 62 and the first mechanism platform 61 and the first horizontal plate 71 can rotate twice. By adjusting the fixing seat 653 to be movably sleeved on the inner side of the clamping hole 657 near the side of the first mechanism platform 61, the second mechanism platform 62 and the first horizontal plate 71 are rotated upward and stacked on the first mechanism platform 61. Then, the third screw 88 is used to fix the rotating plate 651 to avoid the problem that the overall shape is too long and difficult to store.
