[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] like Figure 1 and Figure 3As shown, a flexible storage and handling device is characterized in that it includes a vertical frame 1 and a horizontal frame 2 movably mounted on the vertical frame 1, and also includes a lifting assembly 3 mounted on the vertical frame 1 for driving the horizontal frame 2 to move on the vertical frame 1, and a clamping assembly 4 mounted on the horizontal frame 2 that moves synchronously with the lifting assembly 3.

[0034] It also includes a first drive assembly 5 for driving the lifting assembly 3 to lift and lower, and a second drive assembly 6 for driving the clamping assembly 4 to clamp.

[0035] The clamping assembly 4 includes a slide rail 7 disposed on the crossbeam 2 and a first clamping plate 8 and a second clamping plate 9 slidably disposed on the slide rail 7;

[0036] The second drive assembly 6 includes several first sprockets 10 spaced apart at one end of the crossbeam 2 and several second sprockets 11 spaced apart at the other end of the crossbeam 2. A first chain 12 is wound between the corresponding first sprockets 10 and second sprockets 11. A first connecting block 13 is fixedly disposed between the first clamping plate 8 and the upper end of the first chain 12. A second connecting block 14 is fixedly disposed between the second clamping plate 9 and the lower end of the first chain 12. After the first chain 12 moves around the first sprockets 10 and second sprockets 11, it drives the first clamping plate 8 and the second clamping plate 9 to move towards each other or away from each other. The first connecting block 13 has a clearance groove 15 for avoiding the first chain 12.

[0037] In this embodiment, the crossbeam 2 is fixed to the top of the upright frame 1 and connected to the upright frame 1 via two parallel slide rails 7, allowing it to move up and down along the upright frame 1. A first sprocket 10 and a second sprocket 11 are respectively installed at both ends of the crossbeam 2, and these two sprockets are connected by a sturdy chain. The clamping assembly 4 consists of two parallel slide rails 7, on which a first clamping plate 8 and a second clamping plate 9 are slidably mounted. They can move in opposite directions or backwards by the movement of the chain. The second drive assembly 6 includes a second drive unit for driving the first sprocket 10 to rotate. A first connecting block 13 and a second connecting block 14 are respectively fixed to the ends of the first clamping plate 8 and the second clamping plate 9, connecting to the upper and lower ends of the first chain 12 to ensure that the first clamping plate 8 and the second clamping plate 9 can move synchronously. The first connecting block 13 is designed with a clearance groove 15 to allow the first chain 12 to pass smoothly around the first sprocket 10 and the second sprocket 11, preventing interference between the first chain and the connecting block. This design allows the clamping component 4 to flexibly clamp goods of different sizes, while the lifting component 3 can lift the goods to different heights to meet the needs of warehousing and handling.

[0038] like Figure 1 and Figure 5As shown, as a further technical solution, the lifting assembly 3 includes a first cylinder 17 with a first piston chamber 16 disposed on the upright 1, a first piston rod 18 slidably disposed in the first piston chamber 16, a third sprocket 19 rotatably disposed on the side of the first piston rod 18 away from the first cylinder 17, and a second chain 20 wound around the third sprocket 19 with one end disposed on the first cylinder 17 and the other end disposed on the cross frame 2. After the first piston rod 18 slides in the first piston chamber 16, it is used to drive the cross frame 2 to move on the upright 1.

[0039] In this embodiment, a first cylinder 17 is fixed on the upright frame 1, and a first piston chamber 16 is formed inside the first cylinder 17. A first piston rod 18 is located within the first piston chamber 16 and can slide within it. A third sprocket 19 is fixed to the first piston rod 18. A second chain 20 is also present, one end of which is fixed to the first cylinder 17, and the other end passes over the third sprocket 19 and connects to the cross frame 2. When the pneumatic or hydraulic system drives the first piston rod 18 to move within the first piston chamber 16, the second chain 20 tightens or loosens accordingly, thereby causing the cross frame 2 to move up and down along the upright frame 1. This design allows the cross frame 2 to flexibly rise and fall on the upright frame 1 to adapt to handling needs at different heights. Through this design of the lifting assembly 3, the flexible warehousing and handling device can achieve rapid handling and positioning of goods at different heights, improving the efficiency and flexibility of warehousing operations.

[0040] like Figure 1 As shown, as a further technical solution, the upright frame 1 has a sliding groove 21 on the side near the horizontal frame 2, the horizontal frame 2 is slidably disposed in the sliding groove 21, and the horizontal frame 2 is provided with a rolling wheel 22, which abuts against and rolls in the sliding groove 21.

[0041] In this embodiment, a groove 21 is specially designed on the side of the upright 1 near the horizontal frame 2. This groove 21 extends along the height direction of the upright 1 to guide the movement of the horizontal frame 2. One side of the horizontal frame 2 is designed with a sliding structure that matches the groove 21, allowing it to slide smoothly within the groove 21. To reduce friction and improve movement efficiency during sliding, several rollers 22 are installed on the horizontal frame 2. These rollers 22 are evenly distributed at the bottom of the horizontal frame 2, and they abut and roll within the groove 21. When the horizontal frame 2 needs to move along the upright 1, the rollers 22 contact the inner wall of the groove 21, providing smooth rolling motion, thereby reducing wear and resistance caused by friction and ensuring smooth movement of the horizontal frame 2.

[0042] like Figure 4 , Figure 6 and Figure 7As shown, as a further technical solution, the first drive assembly 5 includes a first lever 23 hinged on the frame 1. The first lever 23 has a first actuating end 24 and a pushing end 25. A second piston rod 26 is hinged on the pushing end 25. The bottom of the first cylinder 17 has a second cylinder 27. The second cylinder 27 has a second piston chamber 28. The second piston rod 26 is slidably disposed in the second piston chamber 28.

[0043] A first connecting pipe 29 is provided between the second piston chamber 28 and the first piston chamber 16. An oil storage chamber 30 is also provided on the second cylinder 27. A second connecting pipe 31 is provided between the second cylinder 27 and the oil storage chamber 30.

[0044] The first connecting pipe 29 has a first check valve 32, and the second connecting pipe 31 has a second check valve 33. The first check valve 32 is in the open state along the direction from the second piston chamber 28 to the first piston chamber 16, and the second check valve 33 is in the open state along the direction from the oil storage chamber 30 to the second piston chamber 28.

[0045] In this embodiment, a first lever 23 is hinged to the support frame 1. The first lever 23 has a first actuating end 24 and a pushing end 25. The pushing end 25 is hinged to a second piston rod 26, which is slidably disposed within the second piston chamber 28 of the second cylinder 27. When the first actuating end 24 is actuated, the second piston rod 26 moves around the hinge point, allowing the pushing end 25 to push the second piston rod 26 to move within the second piston chamber 28. The second cylinder 27 is fixed to the bottom of the first cylinder 17 and has an oil reservoir 30. In the hydraulic system, a first connecting pipe 29 connects the second piston chamber 28 and the first piston chamber 16, while a second connecting pipe 31 connects the second cylinder 27 and the oil reservoir 30. Hydraulic oil flows between the two piston chambers and between the cylinder and the oil reservoir 30. A first check valve 32 is installed on the first connecting pipe 29, allowing hydraulic oil to flow from the second piston chamber 28 to the first piston chamber 16. A second check valve 33 is installed on the second connecting pipe 31, allowing hydraulic oil to flow from the oil reservoir 30 to the second piston chamber 28. This ensures that the hydraulic oil flows only in one direction, preventing reverse flow and thus guaranteeing the stability and precise control of the lifting assembly 3. When the lifting assembly 3 needs to be driven, the second piston rod 26 is moved. Through the linkage of the first lever 23 and the push end 25, the hydraulic system supplies pressurized oil to the second piston chamber 28, which then flows through the first check valve 32 into the first piston chamber 16, causing the first piston rod 18 to move accordingly within the first piston chamber 16. This design makes the movement of the lifting assembly 3 smoother and more controllable, while also improving the efficiency and reliability of the entire flexible storage and handling device. Through this precise hydraulic control, accurate lifting control of the crossbeam 2 can be achieved, meeting the handling needs of goods at different heights.

[0046] like Figure 7 As shown, as a further technical solution, the first drive assembly 5 also includes a third piston chamber 34 disposed in the first cylinder 17. The third piston chamber 34 has a first end 35, a second end 36 and a third end 37. The first end 35 is connected to the first piston chamber 16, the second end 36 is connected to the oil reservoir 30, and a third piston rod 38 is slidably disposed in the third end 37. After the third piston rod 38 slides, it is used to connect or disconnect the first end 35 and the second end 36.

[0047] In this embodiment, a first cylinder 17 is integrated on the support frame 1, and a third piston chamber 34 is designed inside it. This piston chamber has a first end 35, a second end 36, and a third end 37. The first end 35 is connected to the first piston chamber 16, the second end 36 is connected to the oil reservoir 30, and the third end 37 houses a sliding third piston rod 38. By sliding the third piston rod 38, the connection or disconnection between the first end 35 and the second end 36 can be achieved.

[0048] Specifically, when the third piston rod 38 slides to its limit position, the first end 35 and the second end 36 are connected through the internal channel of the third piston chamber 34, allowing hydraulic oil to flow between the first piston chamber 16 and the reservoir 30. This connection is used for the lowering action of the crossbeam 2, because pressurized oil can flow into the reservoir 30, reducing the pressure of the first piston rod 18 in the first piston chamber 16, thereby pushing the crossbeam 2 downward. Conversely, when the third piston rod 38 slides to its other limit position, cutting off the connection between the first end 35 and the second end 36, it can prevent the flow of oil, thereby locking the position of the crossbeam 2 and maintaining its stability.

[0049] like Figure 2 As shown, as a further technical solution, the third piston rod 38 is threaded inside the first cylinder 17. The third piston rod 38 has a gear 39 on the side away from the first cylinder 17. After the gear 39 rotates, it is used to drive the third piston rod 38 to slide in the third end 37. The support frame 1 is also provided with a second lever 40. The second lever 40 has a second lever end 41 and a hinge end 42. It also includes a vertical rod 43 that is hinged to the hinge end 42, and the vertical rod 43 is slidably disposed on the support frame 1.

[0050] It also includes a second actuating end 41 with one end set on the second actuating end 41 and the other end set on the upright 1, which is used to provide the second lever 40 away from the upright 43. The other end of the upright 43 is provided with a toothed plate 44, which meshes with the gear 39. After the upright 43 slides on the upright 1, the toothed plate 44 is used to drive the gear 39 to rotate.

[0051] In this embodiment, the third piston rod 38 adopts a threaded design and is located inside the first cylinder 17. This threaded design allows the third piston rod 38 to move axially within the cylinder through rotational motion. One end of the third piston rod 38 is designed with a gear 39, which interacts with the second lever 40 on the support frame 1. The second lever 40 is a lever arm with two main ends: a second actuating end 41 and a hinged end 42. At the hinged end 42, the second lever 40 is hinged to the support rod 43, which can slide along the support frame 1. One end of the support rod 43 is connected to the hinged end 42 of the second lever 40, and the other end is connected to the support frame 1, forming a lever system. An elastic element is also provided, one end connected to the second actuating end 41 and the other end fixed to the support frame 1, to provide a force for the second lever 40 to move away from the support rod 43, thereby maintaining the tension of the system. The other end of the support rod 43 is equipped with a toothed plate 44, which meshes with the gear 39 on the third piston rod 38. When the upright 43 slides on the frame 1, the toothed plate 44 drives the gear 39 to rotate, which in turn causes the third piston rod 38 to slide within the first cylinder 17, thus realizing the lifting and lowering action of the crossbeam 2. This design allows the position of the third piston rod 38 to be controlled by operating the second lever 40, thereby achieving precise lifting and lowering control of the crossbeam 2.

[0052] like Figure 1 and Figure 5 As shown, as a further technical solution, the bottom of the support frame 1 has a traveling wheel 45, and the support frame 1 also has a handle 46 for pushing the support frame 1 to move.

[0053] As a further technical solution, a rotating disk 47 is rotatably mounted on the cross frame 2, a fourth sprocket 48 is mounted on the rotating disk 47, a fifth sprocket 49 is rotatably mounted on the upright frame 1, a transmission shaft 50 for transmission is provided between the fifth sprocket 49 and the first sprocket 10, and a third chain 51 is wound between the first sprocket 10 and the fifth sprocket 49.

[0054] In this embodiment, the bottom of the upright 1 is equipped with traveling wheels 45, which allow the entire upright 1 to move easily on a flat surface without lifting the entire structure. This design significantly improves the mobility of the handling device, especially when it needs to be moved or repositioned in a large space. The upright 1 is also equipped with a handle 46 for pushing the upright 1. The handle 46 is ergonomically designed to ensure that the operator can comfortably grip and apply force to move the upright 1, its crossbeam 2, and the lifting assembly 3. The position and design of the handle 46 allow the operator to operate with one or two hands, adjusting the position of the upright 1 as needed. A rotating disk 47 is rotatably mounted on the crossbeam 2, and a fourth sprocket 48 is fixed on the rotating disk 47. Simultaneously, a fifth sprocket 49 is also rotatably mounted on the upright 1. These two sprockets are connected by a drive shaft 50, on which a third chain 51 is wound, connecting the first sprocket 10 and the fifth sprocket 49. Such a chain drive system allows power transmission between the rotating disk 47 on the crossbeam 2 and the fifth sprocket 49 on the upright frame 1, thereby controlling the first clamping plate 8 and the second clamping plate 9 by rotating the rotating disk 47.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
