Technical Field

[0001] The utility model relates to the technical field of forklift trucks, in particular to a multifunctional forklift truck. Background Art

[0002] In logistics transportation, the goods need to be transferred, loaded and unloaded, piled and stacked, and the commonly used auxiliary tool is the stacker. Among them, the fully electric stacker is widely used in the logistics industry because of its high degree of automation, convenient control, flexible response, and suitability for heavy loads and long-term cargo transfer.

[0003] The laser sensors in the existing forklift equipment are easily affected by other physical structures around the forklift, and their working accuracy is low, which is prone to errors. In addition, the device has a large number of hydraulic cylinders, and the telescopic efficiency of the hydraulic cylinders is low, resulting in a slow running speed of the forklift, which is not conducive to increasing the speed of material transportation.

[0004] For example, a safe forklift device for a fully electric stacker disclosed in Chinese patent publication number CN217297181 U, the forklift device drives the fork plate seat to slide on the fork plate frame by setting a linear drive component, thereby adjusting the position of the fork plate relative to the fork plate frame, and thus facilitating targeted forklifting of materials of different sizes and specifications; a lateral limit component is set to perform lateral limit protection on the materials on the fork plate to prevent the materials from falling off the fork plate, thereby improving the forklift stability of the utility model.

[0005] First of all, in the above device, the lateral limit protection of the material on the plug plate is completed through the lateral limit assembly to ensure the stability of the fork during the forking process. However, the materials on the fork lack corresponding limit structures on the other two sides, so there is still a possibility of falling off. In addition, when the stacker is moving and the fork is lifting, the material on the fork lacks vertical limit. The goods may vibrate on the fork plate and the lateral limit assembly, and its stability needs to be further strengthened. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 4 , this utility model provides 3 technical solutions:

[0032] Embodiment 1:

[0033] A multifunctional fork of a stacker truck comprises a fork frame 1, the side wall of the fork frame 1 is set as an arc surface, and a fork plate 2 is symmetrically welded on one side of the fork frame 1, a clamping and limiting unit for completing the vertical limit of the goods is installed on the fork frame 1, and the fork plate 2 is provided with an adjustment unit slidably connected with the clamping and limiting unit.

[0034] The clamping and limiting unit includes a clamping plate 301 located directly above the fork plate 2. A hook 303 for limiting the traction cable 302 is arranged on the top of the clamping plate 301. The other end of the traction cable 302 passes through a support plate 304 that is limited and plugged into the fork frame 1. The other end of the traction cable 302 is wound around a twisting roller 305, and the twisting roller 305 is rotatably installed in a connecting seat 306 that is symmetrically welded on the outer wall of the fork frame 1.

[0035] In this embodiment, the limiting traction cable 302 on the hook 303 completes the traction and pulling of the clamping plate 301. During the specific clamping process, the twisting roller 305 is rotated according to the height of the cargo, and the twisting roller 305 completes the release or winding of the limiting traction cable 202.

[0036] The bottom of the clamping plate 301 is arrayed with suction cup openings 301a that fit the goods, and the bottom of the clamping plate 301 is provided with a slide groove for adjusting the sliding connection of the unit.

[0037] The two ends of the clamping plate 301 are symmetrically fixed with hinge shafts 301c on which the corresponding hinge rods 301b are hinged. The other end of the hinge rod 301b is welded to the embedded slider 301d. The embedded slider 301d is slidably connected with the arc groove 101 on the fork frame 1, and the linkage rod 301e is fixedly connected between adjacent embedded sliders 301d.

[0038] In the above, after the limiting traction cable 302 completes the traction and pulling of the pressing plate 301, the limiting traction cable 302 rotates at the hinged rods 301b at both ends, so as to complete the adjustment of the pressing angle of the pressing plate 301 according to the different heights of the goods, and on this basis, the embedded slider 301d slides in the arc groove 101, and the embedded slider 301d can drive the hinged rod 301b to adjust the position, so as to achieve the adjustment of the pressing position of the pressing plate 301 on the goods, and cooperate with the suction cup 301a to absorb the goods tightly, complete the compression limit in the vertical direction, and improve the stability of the goods on the fork plate 2;

[0039] Among the above, this embodiment provides a connection method of the embedded slider 301d and the fork frame 1 to which it is slidably connected. The embedded slider 301d and the fork frame 1 are respectively configured as a permanent magnet and an electromagnet. When the hinge rod 301b and the clamping plate 301 are adjusted in angle and position, the electromagnet and the external magnetic coil are de-energized, the adsorption of the permanent magnet and the electromagnet is cancelled, and the embedded slider 301d is slid in the arc groove 101, and is re-adsorbed after being moved to a suitable position;

[0041] Embodiment 2:

[0042] On the basis of Example 1: the adjustment unit includes a traction slider 401 sliding in the slide groove at the bottom of the clamping plate 301, and a lateral limit rod 403 with a limit guide plate 402 welded at the other end is symmetrically arranged at the bottom of the traction slider 401, the lateral limit rod 403 and the limit guide plate 402 form a "mouth" shaped limit area, and a guide groove 201a is opened in the fork plate 2, and a hydraulic rod 404 with the other end limited on the fork frame 1 is passed through the traction slider 401.

[0043] In this embodiment, the limiting area formed by the side line limiting rod 403 and the guide limiting plate 402 completes the side protection and limiting of the goods on the fork plate 2.

[0044] The left and right ends of the guide groove 201a are symmetrically provided with a limited positioning roller 201b therein and a sliding roller 201c movable therein, a connecting sleeve 201d is provided between the positioning roller 201b and the sliding roller 201c, an electric push rod 201e is limitedly installed between the two connecting sleeves 201d, and the sliding roller 201c passes through the limited guide plate 402 and is rotatably connected to the limited guide plate 402.

[0045] In this embodiment, when the traction slider 402 is pushed by the hydraulic rod 404, the lateral limit rods 403 connected at both ends of the traction slider 402 complete the traction of the limit guide plate 402. Since the limit guide plate 402 needs to be connected to the rotation of the sliding roller 201c, the limit guide plate 402 completes the rotation opening and closing. During the loading process of the fork plate 2, the traction slider 402 slides to the rightmost end or the leftmost end. At this time, the limit guide plate 402 is parallel to the fork plate 2. After the goods are separated from the limit guide plate 402, the traction slider 402 slides, and the limit guide plate 402 is placed vertically or tilted, and the angle adjustment is completed according to different goods, thereby realizing the side limit protection of the goods and further improving the stability.
