The telescopic mechanism 4 is positioned above the fixed base 3, and a sliding body 5 is positioned above the telescopic mechanism 4. The sliding body 5 can move back and forth under the action of the telescopic mechanism 4, thereby driving the fork structure 9 connected to it to move back and forth. One end of the pitching mechanism 7 is fixed to the fixed base 3, and the other end is connected to the fork structure 9 or the sliding body 5 to complete the pitching adjustment action of the fork structure 9. The upper structure can rotate 90 degrees and other angles through the slewing mechanism, and can perform material loading, unloading, and handling operations in both horizontal and vertical directions. The fork structure has multiple compound actions such as pitching, lifting, telescopicing, and fork distance adjustment; this upper structure is supported on the transport chassis and has the function of overall slewing.
[0026] Furthermore, the material handling vehicle with compound motion also includes an auxiliary support mechanism 12, which is disposed on both sides or the bottom of the fork structure 9 to provide additional support during handling. The auxiliary support mechanism 12 includes one or more sets of retractable support legs, which can be hydraulic, electric or manual.
[0027] Furthermore, the material handling vehicle with compound motion also includes a counterweight 6, which is located at the rear of the fork structure 9 to balance the load at the front end of the fork structure 9.
[0028] Furthermore, it also includes a control device (not shown), which is connected to the superstructure and provides power and control functions to the superstructure. Multiple transport vehicles forming a cluster can employ intelligent control strategies, enabling industrial automation and intelligent scheduling operations.
[0029] Furthermore, the fork structure 9 also includes a lifting mechanism 8, multiple forks 11, a fork adjustment mechanism 13, and a back plate 14. The fork adjustment mechanism 13 is disposed among the multiple forks 11 to adjust the distance between the forks 11. The forks 11 and the back plate 14 are connected by welding or bolts. The lifting mechanism 8 completes the up-and-down sliding operation, and the forks 11 lift the workpiece 10. The material handling vehicle completes the lifting, horizontal movement, rotation, and transportation of materials to other workstations through the above-mentioned multiple action mechanisms.
[0030] Furthermore, the sliding body 5 cooperates with the guide rail of the telescopic mechanism 4 via a slider or ball bearing to achieve smooth sliding; the sliding body 5 is fixedly connected to the fork structure 9 via a connector so that the fork structure 9 can extend and retract with the movement of the sliding body 5. The pitch mechanism 7 is directly connected to the fork structure 9 via a connector or indirectly acts on the fork structure 9 via the sliding body 5 to adjust its pitch angle. The fork structure 9 is fixedly connected to the sliding body 5 via a connector so that the fork structure 9 can extend and retract with the movement of the sliding body 5; the pitch angle of the fork structure 9 is adjusted by the extension and retraction of the pitch mechanism 7.
[0031] Furthermore, the transport chassis 1 adopts a rail-mounted, tire-mounted, or tracked design.
[0032] The complete working process of the composite motion material handling vehicle described in this application is as follows:
[0033] (1) Initial state: such as Figure 1 As shown.
[0034] (2) Rotational motion:
[0035] The operator activates the slewing mechanism 2 via the control device, causing the superstructure to rotate relative to the transport chassis 1 to the desired angle. The fork structure 9 then turns towards the target material position, preparing for extension, retraction, and pitching movements.
[0036] (3) Extension and contraction movements:
[0037] The operator activates the telescopic mechanism 4 via the control device, pushing the sliding body 5 forward along the guide rail.
[0038] The sliding body 5 drives the fork structure 9 to extend forward and reach the target material position. At this time, the fork body 11 of the fork structure 9 is ready to lift the workpiece 10.
[0039] (4) Pitching motion:
[0040] Adjust the pitch angle of the fork structure 9 to accommodate the height of the material:
[0041] The operator activates the pitch mechanism 7 via the control device. The extension and retraction of the pitch mechanism 7 adjusts the pitch angle of the fork structure 9 through the connection point (directly or indirectly). When the pitch angle of the fork structure 9 is adjusted to a suitable position, the fork body 11 can accurately lift the workpiece 10.
[0042] (5) Lifting motion:
[0043] The operator activates the lifting mechanism 8 via the control device, which lifts the fork structure 9 upwards via the sliding guide rail. The fork structure 9 then lifts the material to the required height, ready for transport.
[0044] (6) Auxiliary support:
[0045] The operator activates the auxiliary support mechanism 12 via the control device, and the support legs extend to provide additional support.
[0046] (7) Transportation:
[0047] The operator starts the transport chassis 1 through the control device to transport the materials to the target location.
[0048] (8) Uninstallation action:
[0049] The operator activates the telescopic mechanism 4 via the control device, moving the fork structure 9 to the target unloading position.
[0050] The operator activates the pitch mechanism 7 via the control device and adjusts the pitch angle of the fork structure 9 to ensure smooth unloading of materials.
[0051] The operator activates the lifting mechanism 8 via the control device to lower the fork structure 9 to the appropriate position, thus completing the unloading.
[0052] (9) Return to the initial state:
[0053] The operator activates the telescopic mechanism 4 and the pitch mechanism 7 via the control device to restore the fork structure 9 to a horizontal position. The operator then activates the slewing mechanism 2 via the control device to restore the upper structure to its initial position. Finally, the operator activates the auxiliary support mechanism 12 via the control device to retract the support legs.
[0054] Through the above steps, the composite motion material handling vehicle can efficiently and safely complete the material handling and loading / unloading tasks. The coordinated work of each component ensures the flexibility and stability of the handling process, meeting the operational needs under complex working conditions.
[0055] This material handling vehicle can lift and transfer heavy materials or other workpieces. It has good low-speed stability and precise and reliable operation, which can meet the requirements of transferring large materials in confined spaces.
[0056] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
