[0020] 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.

[0021] This utility model relates to a single-column stacker truck, such as... Figure 1 , Figure 4 , Figure 5 As shown, the system includes a main frame, guide wheel assembly 4, drive chain 5, linear guide rail 6, connecting plate 8, quick-release mounting assembly, platform 10, top box 15, safety belt 13, cover plate 17, and electrical control box. The main frame includes a frame body 2, uprights mounted on the frame body 2, a front wheel 3 and a rear wheel 1 mounted on the lower end of the frame body 2. The cover plate 17 is located on the side of the uprights away from the platform 10. The electrical control box is located inside the cover plate 17 and houses control components such as a battery, reducer, motor, DC contactor, and terminals. The front wheel 3 is mounted on the front side of the lower end of the frame body 2 and is a swivel wheel. The rear wheel 1 is mounted on the rear side of the lower end of the frame body 2 and is equipped with a foot brake. The cover plate 17 is made of bent sheet metal, eliminating the need for molds and saving mold costs, while also allowing for a more compact internal structure. A control handle is installed on the upper part of the cover plate 17, which controls the forward, backward, upward and downward functions of the stacker truck; an emergency stop switch, a power meter, a toggle switch and a charging indicator light are installed in the middle.

[0022] Furthermore, in this embodiment, such as Figure 2 , Figure 3 As shown, the column includes a column body 19 and a column cover plate 7. The column body 19 and the column cover plate 7 together enclose the installation area. The guide wheel assembly 4, the transmission chain 5, the linear guide rail 6 and the connecting plate 8 are arranged in the installation area of ​​the column. The guide wheel assembly 4 includes an upper guide wheel and a lower guide wheel respectively arranged at the upper and lower ends of the column body 19, and is used to change the transmission direction of the transmission chain 5.

[0023] Specifically, in this embodiment, such as Figure 2 , Figure 3 As shown, two sets of linear guide rails 6 are provided, arranged in parallel. The front side of the connecting plate 8 is slidably engaged with the linear guide rail 6 via a slider or linear bearing, allowing the connecting plate 8 to reciprocate along the length of the guide rail. A quick-release mounting assembly is installed on the connecting plate 8, and the platform 10 is mounted on the quick-release mounting assembly, thus ensuring that the platform 10 moves linearly along the track direction of the linear guide rail 6. The connecting plate 8 is slidably mounted on the linear guide rail 6 and has a safety belt mounting hole and a long column hole. The two ends of the transmission chain 5 are fixed in the long column hole by bolts or pins, and are wound around the upper and lower guide wheels to form a U-shaped transmission path, ensuring that the chain is always taut during lifting and lowering, preventing derailment or slack.

[0024] Furthermore, in this embodiment, such as Figure 2 , Figure 3 As shown, the top box 15 is set in the installation area and is connected and fixed to the column body 19 by countersunk screws 16. The top box 15 is provided with a mounting base 14, the top of which is flush with the upper end of the column and does not protrude from the end of the column. One end of the safety belt 13 is installed on the mounting base 14, and the other end is fixed to the connecting plate 8 through the safety belt mounting hole. This structure can reduce or avoid damage to the safety belt 13 during transportation.

[0025] Specifically, in this embodiment, such as Figure 2 , Figure 3 As shown, the quick-release mounting assembly includes: a mounting plate 9 detachably connected to a connecting plate 8, a bracket shaft fixed to the mounting plate 9, a plug shaft 12 detachably mounted on the mounting plate 9, an accessory connecting plate sleeved on the bracket shaft, and a pin 11 that cooperates with the plug shaft 12 to fix the accessory connecting plate; wherein, a table panel 10 is mounted on the accessory connecting plate; the mounting plate 9 has a first positioning hole and a second positioning hole, the bracket shaft is fixed to the mounting plate 9 through the first positioning hole, and the plug shaft 12 is detachably connected to the mounting plate 9 through the second positioning hole. One end of the plug shaft 12 has a boss, and the other end has a through hole. The diameter of the boss is larger than the diameter of the second positioning hole. The through hole of the plug shaft 12 is used to insert the pin 11, which can be a cotter pin. The accessory connecting plate has a U-shaped cross-section, with a hook-shaped groove in the upper half and a fixing hole in the lower half. The opening direction of the hook-shaped groove is obliquely downward, and the hook-shaped groove cooperates with the bracket shaft for installation. In use, the hook-shaped groove of the accessory connecting plate hooks onto the bracket shaft, and then the insert shaft 12 passes through the second positioning hole and the fixing hole, and the pin 11 is inserted into the through hole of the insert shaft 12, so as to realize the quick assembly and disassembly between the accessory connecting plate and the mounting plate 9, and thus realize the quick assembly and disassembly of the tabletop 10.

[0026] Furthermore, in this embodiment, the connecting plate 8 can be provided with several positioning grooves, and the mounting plate 9 can be provided with several positioning protrusions that cooperate with each positioning groove. The detachable connection between the mounting plate 9 and the connecting plate 8 is achieved through the cooperation of the positioning grooves and positioning protrusions. In actual use, the detachable connection between the mounting plate 9 and the connecting plate 8 can adopt different connection methods depending on the application. In addition, during actual use, the front side of the accessory connecting plate can not only install the tabletop 10, but also modules such as V-blocks, roller platforms, reel rotators, single-axis, double-axis, and cutter arms. The required modules can be installed according to actual needs.

[0027] It is worth noting that in this embodiment, an electrical control box is installed on one side of the main frame, and a mechanism for raising and lowering the control panel 10 is installed on the other side. Under the action of the motor and reducer, the transmission chain 5 moves, driving the connecting plate 8 to move, and the connecting plate 8 drives the safety belt 13 and the control panel 10 to move. Furthermore, in this embodiment, as... Figure 5 As shown, the column body 19 is also provided with a limit component to limit the extreme positions of the platform 10's lifting and lowering. Specifically, the limit component includes limit switches 18 respectively provided at the upper and lower ends. The range of the platform 10's rising and falling positions can be limited by the limit switches 18 provided at the upper and lower ends.

[0028] As can be seen from the above, the use of a linear guide rail structure maintains straightness during movement, preventing the platform 10 from swaying during lifting and lowering, ensuring stability and improving safety. Furthermore, the top box 15 is installed within the mounting area of ​​the column, not protruding from the end of the column, which reduces or avoids damage to the safety belt 13 during transportation, thus lowering costs.

[0029] 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.
