Detailed implementation manner

[0064] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] In the embodiments of the present invention, please refer to Figures 1 to 12 , a storage rack for warehousing logistics, including side plates 1, placing plates 2 and trays 3. There are two groups of the side plates 1, symmetrically arranged on both sides of the placing plate 2. The side plates 1 are connected to the placing plate 2. There are several groups of the placing plates 2, and they are arranged longitudinally along the side plates 1. The trays 3 are placed on the placing plates 2. It further includes:

[0066] A supporting lifting mechanism 4, used to drive the tray 3 to move longitudinally and pick and place with it. The supporting lifting mechanism 4 includes: a first telescopic member 41, one end of which is connected to the side plate 1; a U-shaped plate 42, connected to the other end of the first telescopic member 41 and slidably connected to the side plate 1; a pushing and pulling assembly 43, one end of which is connected to the rear side of the U-shaped plate 42, and the other end is connected to the tray 3, used to drive the tray 3 to move back and forth along the placing plate 2; a supporting assembly 44, one end of which is connected to the U-shaped plate 42, and the other end is connected to the placing plate 2, used to support the tray 3 in the unfolded state;

[0067] A limiting plate 5, connected to the rear side of the placing plate 2, used to position the tray 3;

[0068] The fixed seat 6 is connected to the supporting component 44. There are several groups of the fixed seats 6, which are arranged in a straight line;

[0069] The ball 7 is rotatably connected to the fixed seat 6. The top of the ball 7 is flush with the bottom of the tray 3.

[0070] The tray 3 is placed on the placement plate 2. When the tray 3 needs to be taken out, the first telescopic member 41 drives the U-shaped plate 42 to move to a specified height, the supporting component 44 unfolds, the pushing and pulling component 43 pushes the tray 3 onto the supporting component 44, and the first telescopic member 41 drives the supporting component 44 to move downward, so as to take down the tray 3 at a high position, facilitating the staff to take down the materials on the tray 3;

[0071] When the tray 3 on the supporting component 44 needs to be placed on the placement plate 2, the first telescopic member 41 drives the supporting component 44 to move to a specified position, and the pushing and pulling component 43 pulls the tray 3 on the supporting component 44 onto the placement plate 2 for placement. The first telescopic member 41 can adopt an electric telescopic rod, a cylinder, etc.

[0072] As an embodiment of the present invention, please refer to Figure 2 , Figure 4 and Figure 5 , the pushing and pulling component 43 includes:

[0073] The fixed hole plate 431 is connected to the rear side of the tray 3, and through holes are formed in the fixed hole plate 431;

[0074] The manipulator 432 is connected to the rear side of the U-shaped plate 42, and the manipulator 432 can perform telescopic movement and rotational movement;

[0075] The pressing plate 433 is connected to the manipulator 432;

[0076] One end of the connecting rod 434 is connected to the pressing plate 433, and the length of the connecting rod 434 is greater than the thickness of the fixed hole plate 431;

[0077] The pulling plate 435 is connected to the other end of the connecting rod 434, and the shape of the pulling plate 435 matches the shape of the through hole.

[0078] The tray 3 is placed on the placement plate 2. When the tray 3 needs to be pushed out, the manipulator 432 drives the pressing plate 433, the connecting rod 434 and the pulling plate 435 to move synchronously. The pulling plate 435 passes through the through hole. When the pressing plate 433 moves to abut against the fixed hole plate 431, the pressing plate 433 continues to move to push the tray 3 onto the supporting plate 446. After the tray 3 is pushed out, the manipulator 432 drives the pressing plate 433 to move in the reverse direction and return to the original position;

[0079] When the tray 3 on the supporting plate 446 needs to be placed on the placing plate 2, the mechanical arm 432 drives the pressing plate 433, the connecting rod 434 and the pulling plate 435 to move synchronously. The pulling plate 435 passes through the through hole. When the pressing plate 433 abuts against the fixed hole plate 431, the mechanical arm 432 rotates, and then drives the pulling plate 435 to rotate, so that the pulling plate 435 is misaligned with the through hole. At this time, the mechanical arm 432 moves in the reverse direction, drives the pulling plate 435 to move in the reverse direction, and pulls the tray 3 to move through the pulling plate 435, so as to pull the tray 3 back to the placing plate 2. After pulling back, the mechanical arm 432 rotates in the reverse direction, so that the pulling plate 435 is aligned with the through hole, and the pulling plate 435 continues to retract to the original position.

[0080] In this embodiment, the shape of the through hole can be a cross through hole, a triangular through hole, a square through hole, a T-shaped through hole, etc. In this application, a cross through hole is preferably used.

[0081] As an embodiment of the present invention, please refer to Figures 1 to 4 、 Figures 6 to 12 , the supporting component 44 includes:

[0082] The connecting plate 441 is rotatably connected to the U-shaped plate 42 at one end through a shaft rod;

[0083] One end of the fixing rope 442 is connected to the other end of the connecting plate 441;

[0084] One end of the vertical plate 4410 is connected to the U-shaped plate 42, and the other end is connected to the other end of the fixing rope 442;

[0085] The clamping block 443 is connected to the connecting plate 441;

[0086] The supporting plate 446 is connected to the fixed seat 6 at the top, and a T-shaped groove is provided on the supporting plate 446;

[0087] The right-angle plate 445 is connected to the supporting plate 446;

[0088] The clamping plate 444 is connected to the side of the right-angle plate 445 away from the placing plate 2;

[0089] The positioning component 447 is connected to the placing plate 2 at one end and the supporting plate 446 at the other end, and is used for positioning the supporting plate 446;

[0090] The rotating component 448 is connected to the U-shaped plate 42 at one end and the supporting plate 446 at the other end, and is used for driving the supporting plate 446 to rotate;

[0091] The resilience component 449 is connected to the supporting plate 446 at one end and the placing plate 2 at the other end.

[0092] In the initial state, the support plate 446 is vertically arranged with the side plate 1, and the positioning assembly 447 positions the support plate 446 so that the support plate 446 can only move horizontally;

[0093] When the top tray 3 needs to be removed, the telescopic member 41 drives the U-shaped plate 42 to move, and then drives the connecting plate 441 to move to the same height as the supporting plate 446, and the rotating assembly 448 works to drive the positioning assembly 447 to move, and release the positioning of the supporting plate 446 by the positioning assembly 447. After the positioning is released, the rotating assembly 448 continues to move, driving the supporting plate 446 to rotate. During the rotation of the supporting plate 446, the rebound assembly 449 supports and limits the supporting plate 446, and the supporting plate 446 drives the card plate 444 to rotate synchronously. When the card plate 444 rotates to engage with the card block 443, the rebound assembly 449 cannot play a supporting role, and the card block 443 supports the supporting plate 446. When the supporting plate 446 rotates 90 degrees and is parallel to the side plate 1, the push-pull assembly 43 pushes the tray 3 onto the supporting plate 446, and the telescopic member 41 moves downward, thereby driving the tray 3 to move downward, making it convenient for the staff to take out the materials on the top tray 3.

[0094] In this embodiment, the right-angle plate 445 can limit the position of the tray 3 to prevent the tray 3 from being separated from the placement plate 2 and the supporting plate 446 under the action of external force.

[0095] As an embodiment of the present invention, please refer to Figures 1 to 4 , Figures 6 to 9 , Figure 12 , the positioning component 447 includes:

[0096] The top of the telescopic folding rod 4471 is connected to the bottom of the supporting plate 446;

[0097] The connecting inclined plate 4472 is connected to the bottom end of the telescopic folding rod 4471, and the end close to the side plate 1 is a bevel structure;

[0098] The fixing plate 4473 is disposed in the T-shaped groove and is movably connected to the supporting plate 446. A straight groove is formed on the fixing plate 4473;

[0099] The positioning rod 4474 is connected to the connecting inclined plate 4472 and is clamped with the straight groove on the fixing plate 4473;

[0100] The elastic member 4475 has a bottom end connected to the supporting plate 446 and a bottom end connected to the connecting inclined plate 4472.

[0101] In the initial state, the support plate 446 is arranged horizontally (perpendicularly to the side plate 1), the fixing plate 4473 is located in the T-shaped groove in the support plate 446, and the positioning rod 4474 is engaged with the straight groove. At this time, the support plate 446 can only move horizontally and linearly;

[0102] When the supporting plate 446 needs to be rotated, the rotating assembly 448 moves and abuts against one end of the hypotenuse structure of the connecting inclined plate 4472, causing the connecting inclined plate 4472 to move downward under the limiting action of the telescopic folding rod 4471. The connecting inclined plate 4472 drives the positioning rod 4474 to move downward synchronously, so that the positioning rod 4474 disengages from the fixing plate 4473 (that is: at this time, the top end of the positioning rod 4474 is located at the bottom of the fixing plate 4473), and the positioning of the supporting plate 446 is released. At this time, the rotating assembly 448 continues to move, driving the supporting plate 446 to rotate to be parallel to the side plate 1. The setting of the first elastic member 4475 ensures that when the rotating assembly 448 disengages from the connecting inclined plate 4472, the connecting inclined plate 4472 can return to its original position and be re-engaged with the straight groove.

[0103] As an embodiment of the present invention, please refer to Figures 1 to 4 、 Figures 6 to 12 and the rotating assembly 448 includes:

[0104] A rotating rod 4481, which penetrates through one end of the supporting plate 446 close to the side plate 1 and is connected to the supporting plate 446;

[0105] A toothed ring 4482, which is connected to the rotating rod 4481 and is located at the bottom of the supporting plate 446;

[0106] A second telescopic member 4483, one end of which is connected to the U-shaped plate 42;

[0107] A toothed plate 4484, which is connected to the other end of the second telescopic member 4483;

[0108] A limiting assembly 4485, one end of which is connected to the U-shaped plate 42 and the other end of which is connected to the rotating rod 4481;

[0109] The limiting assembly 4485 includes:

[0110] An inclined frame plate 44851, which is rotatably connected to the rotating rod 4481. Both the upper and lower sides of the inclined frame plate 44851 are hypotenuse structures, and the height of one end close to the fixed seat 6 is higher than the other end. A plurality of groups of the inclined frame plates 44851 are longitudinally arranged, and their horizontal lengths gradually increase. A sliding groove 44852 is provided on the inclined frame plate 44851;

[0111] A positioning block 44853, which is connected to the U-shaped plate 42 and is slidably engaged with the sliding groove 44852.

[0112] The first telescopic member 41 drives the U-shaped plate 42 to move to the same height as the supporting plate 446. At this time, the positioning block 44853 is engaged with the chute 44852 on the inclined frame plate 44851 at this position to restrict the inclined frame plate 44851. The second telescopic member 4483 drives the toothed plate 4484 to move horizontally in a straight line. The toothed plate 4484 first abuts against the hypotenuse side of the connecting inclined plate 4472, causing the connecting inclined plate 4472 to move downward. When the positioning rod 4474 disengages from the fixed plate 4473, the toothed plate 4484 moves to engage with the toothed ring 4482, driving the toothed ring 4482 to rotate. The toothed ring 4482 drives the rotating rod 4481 and the supporting plate 446 to rotate synchronously around the central axis of the rotating rod 4481. The second telescopic member 4483 can be an electric telescopic rod, a cylinder, etc.

[0113] As an embodiment of the present invention, please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 8 , the rebounding assembly 449 includes:

[0114] An arc barrel 4491, connected to the bottom of the supporting plate 446. The center of the arc barrel 4491 and the central axis of the rotating rod 4481 are on the same vertical line;

[0115] An arc rod 4492, rotatably and engagingly connected to the arc barrel 4491;

[0116] A telescopic rod 4493, with one end connected to the arc rod 4492 and the other end connected to the placing plate 2;

[0117] A second elastic member 4494, with one end connected to the arc rod 4492 and the other end connected to the placing plate 2.

[0118] After the tray 3 is pushed onto the supporting plate 446, and at this time the inclined frame plate 44851 is located between the rear side of the tray 3 and the front side of the placing plate 2; during the downward movement of the U-shaped plate 42, the supporting plate 446 is driven to move downward synchronously through the connecting plate 441, the clamping block 443 and the clamping plate 444. The supporting plate 446 drives the inclined frame plate 44851 to move downward synchronously. Since the horizontal lengths of several groups of inclined frame plates 44851 gradually increase from top to bottom, when the top inclined frame plate 44851 moves downward, it will squeeze the bottom inclined frame plate 44851, causing the squeezed inclined frame plate 44851 to move horizontally, driving the horizontally arranged supporting plate 446 connected to the squeezed inclined frame plate 44851 to move horizontally. The arc barrel 4491 and the arc rod 4492 move synchronously, and the second elastic member 4494 undergoes elastic deformation. When the top inclined frame plate 44851 disengages from the squeezed inclined frame plate 44851, under the reaction force of the second elastic member 4494, the horizontally arranged inclined frame plate 44851 returns to its original position;

[0119] In this embodiment, during the rotation of the supporting plate 446, the supporting plate 446 drives the arc-shaped cylinder 4491 to rotate synchronously along the arc-shaped rod 4492. Since the arc-shaped cylinder 4491 is rotationally clamped with the arc-shaped rod 4492, during the rotation of the supporting plate 446, it can be supported to prevent the supporting plate 446 from falling. The supporting plate 446 drives the clamping plate 444 to rotate synchronously. When the clamping plate 444 rotates to be clamped with the clamping block 443, the arc-shaped cylinder 4491 is disengaged from the arc-shaped rod 4492. At this time, the clamping block 443 cooperates with the clamping plate 444 to support the supporting plate 446. The second elastic member 4494 can be a spring, a spring sheet, etc. In this embodiment, the horizontally arranged supporting plate 446 refers to the supporting plate 446 that is perpendicular to the side plate 1.

[0120] As an embodiment of the present invention, please refer to Figure 1 、 Figure 2 and Figure 4 , the supporting and lifting mechanism 4 further includes: a sliding assembly 45 for ensuring the stable movement of the U-shaped plate 42. The sliding assembly 45 includes:

[0121] a groove plate 451 connected to the side plate 1;

[0122] a slider 452 connected to the U-shaped plate 42 and slidably clamped with the groove plate 451.

[0123] During the movement of the U-shaped plate 42, the slider 452 is driven to slide in the groove plate 451, restricting the movement path of the U-shaped plate 42 and improving the stability and reliability during the working process.

[0124] As an embodiment of the present invention, please refer to Figures 1 to 4 、 Figure 7 , the supporting assembly 44 further includes: a retracting and extending assembly 440 for retracting the connecting plate 441. The retracting and extending assembly 440 includes:

[0125] a volute spring 4401, one end of which is connected to the shaft rod on the connecting plate 441;

[0126] a fixed ring 4402 connected to the other end of the volute spring 4401 and connected to the U-shaped plate 42;

[0127] a retractable folding plate 4403 connected to the bottom of the side plate 1 and located directly below the connecting plate 441.

[0128] When it is necessary to retract the connecting plate 441, the U-shaped plate 42 drives the connecting plate 441 to move downward, so that the connecting plate 441 abuts against the retractable folding plate 4403. The U-shaped plate 42 continues to move downward, and the connecting plate 441 drives the retractable folding plate 4403 to rotate around the shaft rod, so that the connecting plate 441 rotates to a vertical state, thereby retracting the connecting plate 441;

[0129] When it is necessary to carry the tray 3, the U-shaped plate 42 drives the connecting plate 441 to move upward. Under the reaction force of the scroll spring 4401, the connecting plate 441 rotates around the shaft rod to the horizontal state.

[0130] The working principle of the present invention is as follows: In the initial state, the arc barrel 4491 and the arc rod 4492 are in a rotational clamping state. The supporting plate 446 is horizontally arranged (perpendicular to the side plate 1). The fixing plate 4473 is located in the T-shaped groove inside the supporting plate 446, and the positioning rod 4474 is clamped with the straight groove. At this time, the supporting plate 446 can only move horizontally in a straight line;

[0131] When it is necessary to take out the tray 3 at a certain height, the first telescopic member 41 drives the U-shaped plate 42 to move upward to a specified position, and then drives the connecting plate 441 to move to the same height as the supporting plate 446. At this time, the positioning block 44853 is clamped with the chute 44852 on the inclined frame plate 44851 at this place, restricting the inclined frame plate 44851;

[0132] The second telescopic member 4483 drives the toothed plate 4484 to move horizontally in a straight line. The toothed plate 4484 first abuts against the hypotenuse side of the connecting inclined plate 4472, causing the connecting inclined plate 4472 to move downward. When the positioning rod 4474 disengages from the fixing plate 4473, the toothed plate 4484 moves to engage with the toothed ring 4482, driving the toothed ring 4482 to rotate. The toothed ring 4482 drives the rotating rod 4481 and the supporting plate 446 to rotate synchronously around the central axis of the rotating rod 4481. During the rotation of the supporting plate 446, the supporting plate 446 drives the arc barrel 4491 to rotate synchronously along the arc rod 4492. Since the arc barrel 4491 and the arc rod 4492 are in rotational clamping, during the rotation of the supporting plate 446, it can be supported to prevent the supporting plate 446 from falling. The supporting plate 446 drives the clamping plate 444 to rotate synchronously. When the clamping plate 444 rotates to be clamped with the clamping block 443, the arc barrel 4491 and the arc rod 4492 are disengaged. At this time, the clamping block 443 cooperates with the clamping plate 444 to support the supporting plate 446. When the supporting plate 446 rotates to be parallel to the side plate 1 (the supporting plate 446 rotates by 90 degrees), the second telescopic member 4483 stops moving. At this time, the pushing and pulling assembly 43 works to push the tray 3 on the placing plate 2 to the supporting plate 446. The setting of the fixing seat 6 and the ball 7 makes the movement of the tray 3 smooth. The tray 3 moves to abut against the right-angle plate 445 and stops moving. The pushing and pulling assembly 43 returns to the original position. At this time, the inclined frame plate 44851 is located between the rear side of the tray 3 and the front side of the placing plate 2;

[0133] The telescopic member 41 drives the U-shaped plate 42 to move downward. During this process, the U-shaped plate 42 drives the supporting plate 446 to move downward synchronously through the connecting plate 441, the clamping block 443 and the clamping plate 444, thereby driving the tray 3 to move downward. The supporting plate 446 drives the inclined frame plate 44851 to move downward synchronously. Since the horizontal lengths of several groups of inclined frame plates 44851 gradually increase from top to bottom, when the top inclined frame plate 44851 moves downward, it will squeeze the bottom inclined frame plate 44851, causing the squeezed inclined frame plate 44851 to move horizontally, driving the horizontally arranged supporting plate 446 connected to the squeezed inclined frame plate 44851 to move horizontally. The arc-shaped cylinder 4491 and the arc-shaped rod 4492 move synchronously, and the elastic member 4494 undergoes elastic deformation. When the top inclined frame plate 44851 is separated from the squeezed inclined frame plate 44851, under the reaction force of the elastic member 4494, the horizontally arranged inclined frame plate 44851 returns to its original position;

[0134] When the high-place tray 3 moves to the bottom, it is convenient for the staff to take out the materials on the tray 3.
