[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0030] The embodiments of this utility model relate to a portable stacker, such as... Figure 1 , Figure 2As shown, the system includes a main frame, a fork assembly, two first square tubes 6, two outriggers 3, a first locking assembly 7, two second square tubes 8, a second locking assembly 5, a pressure plate 11, and a hydraulic control system. Specifically, the main frame has two parallel uprights 12, a base rod and a top rod connecting the two uprights 12, a mounting rod located between the top rod and the base rod, two balance wheels 9 and two casters 4 with brakes mounted on the base rod; the uprights 12 have slide rails along their length; the fork assembly has a bracket 16, guide wheels 15 connecting the bracket 16 and the uprights 12, a connecting shaft 18 mounted on the bracket 16, and forks 1 detachably mounted on the connecting shaft 18; the hydraulic control system includes a cylinder 14 mounted on the mounting rod and a control rod 19 connected to the cylinder 14, which controls the start and stop of the cylinder 14. The guide wheel 15 is slidably mounted on the slide rail, and the control lever 19 controls the hydraulic cylinder 14 to drive the bracket 16 to rise and fall along the length of the column 12. Through holes are opened at both ends of the connecting shaft 18, into which pins 17 are inserted. The fork 1 has mounting holes passing through the connecting shaft 18 and storage holes perpendicular to the mounting holes. The fork 1 is used to load goods. In this embodiment, the fork 1 is L-shaped, including a vertical section and a horizontal section perpendicular to each other. The mounting hole and storage hole are both located on the vertical section, which is fixed to the connecting shaft. The horizontal section is used to lift goods. When the fork 1 needs to be disassembled, the pin 17 is removed from the through hole, and the connecting shaft 18 can be removed from the bracket 16, thus allowing the fork 1 to be removed from the connecting shaft 18. When the fork 1 needs to be installed, the fork 1 is installed on the connecting shaft 18 through the mounting hole, the connecting shaft 18 is installed on the bracket 16, and then the pin 17 is inserted into the corresponding through hole, thus enabling the installation and disassembly of the fork 1. In actual use, the type of pin 17 can be selected according to the application, such as a quick-release spring pin or a cotter pin.

[0031] Furthermore, in this embodiment, such as Figure 1 , Figure 2 As shown, two first square tubes 6 are symmetrically arranged at both ends of the base rod, and two support legs 3 are detachably installed in the corresponding first square tubes 6. A front wheel 2 is provided on the side of the support leg 3 away from the first square tube 6. The two first square tubes 6 are also used to place the forks 1 when the stacker is folded. When the stacker is in working condition, the support legs 3 are placed in the first square tubes 6 and locked to the first square tubes 6 by the first locking assembly 7. When the stacker needs to be folded, the first locking assembly 7 is unlocked to separate the support legs 3 from the first square tubes 6, and the forks 1 are inserted into the first square tubes 6 from the side with the storage hole. Then, the forks 1 are locked to the first square tubes 6 by the first locking assembly 7.

[0032] Furthermore, in this embodiment, such as Figure 1 , Figure 2As shown, two second square tubes 8 are respectively positioned above the corresponding first square tubes 6, and the length direction of the second square tubes 8 is perpendicular to the length direction of the first square tubes 6. When the stacker needs to be folded, the support leg 3 separates from the first square tube 6 and is inserted into the second square tube 8. The second square tube 8 and the support leg 3 are locked and fixed by the second locking assembly 5. Two pressure plates 11 are provided, which are respectively set on the side wall of the corresponding column 12 by screws 20 and the third locking assembly 10. After the third locking assembly 10 is unlocked, the pressure plate 11 can rotate around the screw 20. Specifically, in this embodiment, the first locking assembly 7, the second locking assembly 5, and the third locking assembly 10 are all knob plungers.

[0033] In addition, in this embodiment, such as Figure 1 , Figure 2 As shown, the portable stacker also includes push handles 13 symmetrically arranged on the uprights 12. The push handles 13 are located on the side of the uprights 12 away from the truck. In addition, the casters 4 in the main frame are equipped with brakes. Pressing the brakes can lock the stacker to prevent it from moving. When the stacker is in operation, the main frame is pushed by the push handles 13, and the stacker is moved by the casters 4 and the front wheels 2. When the stacker needs to be folded, the brakes are pressed to prevent the stacker from moving during the folding process. When the stacker is tilted back about 45 degrees by the push handles 13, the push handles 13 are released, and the balance wheels 9 and the casters 4 can support the main frame to ensure that the main frame is stable and does not move.

[0034] Specifically, when loading and unloading goods, the hydraulic cylinder 14 is operated via the control lever 19, driving the forks 1 to rise and fall along the guide rail via the guide wheels 15, thus stacking or unloading palletized goods; the stacker is pushed by the push handle 13, and the front wheels 2 and swivel wheels 4 move and steer in coordination to complete short-distance transportation. When the stacker needs to be folded for transportation, firstly, as... Figure 3 As shown, by operating the control lever 19, the cylinder 14 is lowered to its lowest position, the third locking assembly 10 is released, and the brake is pressed to lock the caster 4, ensuring the stacker truck stops moving and ensuring safe operation. The pressure plate 11 is rotated around the screw 20 to a preset position to press down on the bracket 16, preventing the bracket 16 from moving and further ensuring safe operation. Then, as... Figure 4 As shown, grip the push handle 13 with both hands, tilting the stacker truck backward at approximately 45 degrees. Release the push handle 13, using the balance wheel 9 and caster wheels 4 to support the main frame and stabilize the stacker truck. Then, as... Figure 5 As shown, loosen the first locking assembly 7 and pull out the support leg 3; then insert the support leg 3 into the second square tube 8, and lock the second square tube 8 and the support leg 3 together using the second locking assembly 5. Then, as... Figure 6 As shown, press down the main frame to lower the stacker, so that the front wheel 2 and balance wheel 9 touch the ground to support the stacker; pull out the pins 17 on both sides of the connecting shaft 18 to remove the forks 1. Finally, as shown... Figure 7 As shown, the two forks 1 are respectively inserted into the corresponding first square tubes 6, and the first locking assembly 7 locks the first square tubes 6 and forks 1 in place, thus completing the stacker folding process. Figure 8 As shown, after folding, the stacker can be lifted by one operator and placed on the truck bed. Then, the stacker can be lifted from the other end and pushed into the truck bed. Therefore, the stacker can be easily put into the truck bed and travel with the truck, which expands the scope of use and makes it more flexible. In addition, the space occupied by the stacker after disassembly and folding is reduced, which effectively reduces transportation costs.

[0035] As can be seen from the above, due to the detachable design of the outriggers 3 and forks 1, the stacker can be folded. After being folded, the stacker can be easily put into the truck bed and travel with the truck, making it convenient to load and unload goods at any time, thus expanding its scope of use. In addition, the stacker occupies less space after being disassembled and folded, effectively reducing the packaging volume and lowering transportation costs.

[0036] Those skilled in the art will understand that the above embodiments are specific examples of implementing this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
