Description

An adjustable fork arm structure for an AGV (Automated Guided Vehicle) Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) equipment technology, and more specifically, to an AGV fork arm adjustment structure. Background Technology

[0002] AGVs (Automated Guided Vehicles) are widely used in unmanned warehouses to pick up pallets using their forks, thereby moving stored goods. The forks are typically suspended from the AGV via a mast. However, in actual production, slight errors in processing and assembly can cause the forks, directly mounted on the mast, to droop or tilt upwards at the fork tips. This affects the height of the fork tips, preventing the AGV's forks from functioning properly. Rework would require significant manpower and resources. Therefore, this paper provides an AGV fork adjustment structure that, through fine adjustments, eliminates tolerable errors during fork production, thus preventing drooping or tilting of the fork tips.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] This utility model provides an adjustment structure for the fork arm 2 of an AGV trolley, as shown in Figure 1, including: a mast 1 for connecting with the AGV trolley, at least one fork arm 2, and at least one adjustment component 3 disposed on the fork arm 2 for adjusting the relative angle between the fork arm 2 and the mast 1; the mast 1 is provided with at least one sliding groove 11 corresponding to the adjustment component 3; one end of the adjustment component 3 is slidably housed in the sliding groove 11; the other end of the adjustment component 3 is detachably connected to the fork arm 2.

[0021] Specifically, compared to the traditional direct suspension connection between the fork arm 2 and the gantry 1, the fork arm 2 is connected to the gantry 1 through the adjustment component 3. When it is found that the tip of the fork arm 2 is tilted up or drooping, the relative angle between the fork arm 2 and the gantry 1 is adjusted by the adjustment component 3, thereby solving the problem of the tip of the fork arm 2 tilting up or drooping.

[0022] In the preferred embodiment, as shown in FIG1, the gantry 1 is equipped with two forks 2, and two adjusting components 3 are provided on the forks 2 and connected to the gantry 1 assembly to increase stability and adjustability.

[0023] Further, the adjustment assembly 3 includes: an adjustment plate 31, a plurality of guide wheels 32 for sliding in the slide groove 11, a transition plate 33 for connecting and fixing to the fork arm 2, a pin 34 for allowing the fork arm 2 to rotate relative to the transition plate 33, and at least one adjustment member 35 for adjusting the relative angle between the fork arm 2 and the transition plate 33; the plurality of guide wheels 32 are rotatably connected to one end of the adjustment plate 31 respectively; the plurality of guide wheels 32 are slidably placed in the slide groove 11 and abut against the inner wall of the slide groove 11 respectively; the transition plate 33 is fixedly connected to the other end of the adjustment plate 31; the transition plate 33 is provided with a plurality of screw holes for bolting the fork arm 2; the adjustment member 35 is disposed on the end of the adjustment plate 31 near the fork arm 2, and the adjustment member 35 is detachably connected to the fork arm 2; one end of the pin 34 is detachably connected to the transition plate 33, and the other end of the pin 34 is rotatably connected to the fork arm 2.

[0024] In Embodiment 1, as shown in Figures 1-2, the guide wheel 32 on the adjusting plate 31 allows the adjusting plate 31 to slide up and down on the slide groove 11 on the gantry 1. When the fork arm 2 is raised and lowered, it can be moved up and down to avoid affecting the normal operation of the fork arm 2.

[0025] As shown in Figure 2-3, during the angle adjustment of the fork arm 2, the fork arm 2 is rotated at a certain angle by the adjusting member 35, so that the fork arm 2 can rotate with the pin 34 on the adjusting plate 31 as the center. After adjusting to a suitable angle, the position of the fork arm 2 is limited and fixed by the adapter plate 33, thereby realizing the angle adjustment of the fork arm 2.

[0026] Specifically, the fork arm 2 has corresponding holes at the corresponding positions, which are used to mate with the screw holes on the adapter plate for relative fixation; after the fork arm 2 is rotated at a slight angle, the hole alignment is not affected, further increasing the scene adaptability.

[0027] Furthermore, the adjusting component 35 includes: a first adjusting block 351 and an adjusting bolt 352; the first adjusting block 351 has a first adjusting screw hole; the adjusting bolt 352 is threadedly connected to the first adjusting through hole 353; the adjusting bolt 352 passes through the first adjusting through hole 353 and is threadedly connected to the fork arm 2.

[0028] In Embodiment 2, as shown in Figure 3, one end of the adjusting bolt 352 is threadedly connected to the fork arm 2. By rotating and turning the adjusting bolt 352 to adjust the relative position of the first adjusting through hole 353, the distance between the adjusting fork arm 2 and the first adjusting block 351 is changed, thereby achieving the effect of slight rotation of the fork arm 2.

[0029] Furthermore, the fork arm 2 is provided with a second adjusting block 21 corresponding to the first adjusting block 351; the second adjusting block 21 is provided with a second adjusting through hole 22; the adjusting bolt 352 is threadedly connected to the second adjusting through hole 22.

[0030] In Embodiment 3, as shown in Figures 3-4, when the adjusting bolt 352 is screwed into the second adjusting screw hole, the relative distance between the first adjusting block 351 and the second adjusting block 21 changes when the adjusting bolt 352 is turned, thereby causing the fork arm 2 to rotate at a certain angle, thus achieving the effect of adjusting the fork arm 2.

[0031] Furthermore, at least one auxiliary wheel 4 for assisting sliding is provided on one end of the adapter plate 33 near the gantry 1; the auxiliary wheel 4 is slidably placed in the slide groove 11, and the auxiliary wheel 4 abuts against the inner wall of the slide groove 11.

[0032] In embodiment four, the auxiliary wheel 4 makes the adjustment plate 31 move up and down more stably within the slide groove 11.

[0033] In the specific implementation process, the fork arm 2 is connected to the gantry 1 through the adjustment component 3, thereby realizing the telescopic fork arm 2's fork-lifting function;

[0034] When the tip of the fork arm 2 is found to be tilted upwards, loosen the fixing bolts between the fork arm 2 and the adapter plate 33 on the adjusting plate 31, so that the fork arm 2 and the adjusting plate 31 can rotate relative to each other. At this time, tighten the adjusting bolt 352 to adjust the relative distance between the first adjusting block 351 on the adjusting plate 31 and the second adjusting block 21 on the fork arm 2, so that they move away from each other, thereby driving the fork arm 2 to rotate counterclockwise around the pin 34 on the adjusting plate 31, so that the tip of the fork arm 2 droops down to counteract the problem of the tip of the fork arm 2 tilting upwards in the initial state. After the adjustment is completed, tighten the fixing bolts between the fork arm 2 and the adapter plate 33 on the adjusting plate 31, so that the fork arm 2 and the adjusting plate 31 are relatively stationary, and the fork arm 2 can work normally at this time.

[0035] When the tip of the fork arm 2 is found to be drooping, loosen the fixing bolts of the fork arm 2 and the adapter plate 33 on the adjusting plate 31, so that the fork arm 2 and the adjusting plate 31 can rotate relative to each other. At this time, tighten the adjusting bolt 352 to adjust the relative distance between the first adjusting block 351 on the adjusting plate 31 and the second adjusting block 21 on the fork arm 2, so that they are closer to each other, thereby driving the fork arm 2 to rotate clockwise around the pin 34 on the adjusting plate 31, thereby making the tip of the fork arm 2 tilt upward to counteract the problem of the tip of the fork arm 2 drooping in the initial state. After the adjustment is completed, tighten the fixing bolts of the fork arm 2 and the adapter plate 33 on the adjusting plate 31, so that the fork arm 2 and the adjusting plate 31 are relatively stationary, and the fork arm 2 can work normally at this time.

[0036] This utility model discloses an adjustment structure for the fork arm 2 of an AGV trolley. The fork arm 2 is connected to the mast 1 on the AGV trolley through an adjustment component 3. When the fork arm 2 deviates and causes the tip of the fork arm 2 to tilt upward or downward, the relative angle between the fork arm 2 and the mast 1 can be adjusted by the adjustment component 3, thereby solving the problem of the tip of the fork arm 2 tilting upward or downward.
