[0050] Example

[0051] like Figure 1-4 As shown, the present invention provides a manual forklift, comprising: a bracket 1, a rotating gear 2, a guide rod 4, a moving rod 5, and a chain 7. The bracket 1 is an "L"-shaped structure, symmetrically and parallel to each other, with a first groove 100 and a second groove 110 provided on the bracket 1 in the vertical direction. The two rotating gears 2 are respectively provided on the side of the two brackets 1 close to each other. The rotating gears 2 are externally connected to a rotating motor 3. The two ends of the guide rod 4 are respectively restricted in the first groove 100 of the two brackets 1 for up and down movement. The two ends of the moving rod 5 are respectively restricted in the second groove 110 of the two brackets 1 for up and down movement. The moving rod 5 is connected to a receiving assembly 6. The chain 7 is cooperatively provided on the rotating gear 2. One end of the chain 7 is connected to the guide rod 4 and the other end is connected to the moving rod 5. In this device, the receiving assembly 6 is driven by the rotating motor 3 to move up and down in the direction of the second groove 110. The provision of the guide rod 4 makes the moving rod 5 more stable during the up and down movement.

[0052] In this embodiment, the supporting assembly 6 includes: a support plate 600 and a supporting plate 610. The support plate 600 is vertically connected to the movable rod 5. One end of the supporting plate 610 is horizontally connected to the lower edge of the support plate 600. The supporting plates 610 are arranged at intervals, wherein the extension direction of the supporting plate 610 is the same as the extension direction of the horizontal limb of the bracket 1.

[0053] In this embodiment, it also includes: a moving component 8, which includes: a connecting frame 800, a main rotating wheel component 810, the connecting frame 800 is horizontally arranged at the lower end of the two brackets 1, the connecting frame 800 extends in the opposite direction of the extension direction of the receiving plate 610, and two groups of first connecting blocks 801 extend downward from both ends of the connecting frame 800. The main rotating wheel component 810 is arranged below the two ends of the connecting frame 800, and the main rotating wheel component 810 includes: a rotating wheel 8100, a limiting tube 8102, and a limiting rod 8 103, spring 8104, a second connecting block 8101 extends horizontally from the center of both sides of the rotating wheel 8100, a limiting tube 8102 is vertically arranged on the second connecting block 8101, one end of the limiting rod 8103 is fixed on the first connecting block 801, and the other end is vertically restricted in the limiting tube 8102 to move up and down, the spring 8104 is arranged on the outer surface of the limiting tube 8102 and the limiting rod 8103, and the spring 8104 is arranged between the first connecting block 801 and the second connecting block 8101. By setting up the moving component 8, when using the manual forklift, before receiving materials, the operator steps on the connecting frame 800 to compress the spring 8104, so that the receiving plate 610 is tilted, preferably as Figure 1 As shown, the second connecting block 8101 where the two rotating wheels 8100 are close to each other is connected through an auxiliary frame. However, when the material needs to be dumped, while lowering the load-bearing plate, the auxiliary frame and the handrail bracket 1 are stepped on, so that the spring 8104 is in a stretched state, thereby allowing the auxiliary bracket 1 to tilt toward the material.

[0054] In this embodiment, two sets of adjustment holes 120 are provided on the side of the two brackets 1 that are adjacent to each other. The system also includes two sets of auxiliary wheel assemblies 9, which include auxiliary wheels 900, adjustment members 910, and connecting rods 920. The adjustment members 910 are provided on the side of the auxiliary wheels 900 that is adjacent to the adjacent bracket 1. The adjustment members 910 are constrained within the adjustment holes 120, allowing for horizontal and vertical movement. The ends of the connecting rods 920 connect to the centers of the adjacent sides of the two auxiliary wheels 900. The auxiliary wheel assemblies 9 are configured in conjunction with the movable assembly 8. When the movable assembly 8 drives the bracket 1 to tilt, the auxiliary wheels 900 can move up and down in the adjustment holes 120.

[0055] In this embodiment, it also includes: a handle 10 and a protective mesh cover 11. The handle 10 is arranged on the side of the bracket 1 away from the receiving plate 610. The control end of the rotating motor 3 is arranged on the handle 10. The two ends of the protective mesh cover 11 are connected to the two brackets 1. The protective mesh cover 11 is close to the side of the handle 10. The handle 10 is convenient for the operator to drive the manual forklift to move. The protective cover can prevent the operator's hand from contacting the gear, thereby increasing the safety of the operation. The control end of the rotating motor 3 is set on the handle 10. When the operator controls the up and down movement of the supporting plate, the manual movement path is reduced, thereby improving work efficiency.

[0056] In this embodiment, when there are multiple production lines and a manual forklift is needed, a call display device is set on one side of the bracket 1 of the manual forklift, and several first signal lights are set on the call display device to number each production line. Each production line corresponds to a second signal light, and the first signal light and the second signal light are linked. The first signal light and the second signal light are connected to the PLC control end. When the operator needs to use a forklift in front of one of the production lines, the second signal light corresponding to the production line is turned on, and the first signal lights corresponding to the second signal lights on several manual forklifts flash. The operator corresponding to one of the manual forklifts turns off the first signal light to represent the acceptance of the task, and the second signal light corresponding to the production line is turned off. The operator controls the manual forklift to reach the designated production line. The setting of the call display device makes it possible for manual calls or pager calls to be chaotic when facing large factories and are greatly affected by factory noise.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
