[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] Example 1

[0030] See also Figure 1As shown, the utility model relates to a fork structure of a rider-type three-way stacker, including a bridge frame 1 identical to the prior art, a fork frame 2 rotatably connected to the front part of the bridge frame 1, and a rotary drive device 3 arranged on the bridge frame 1 for driving the fork frame 2 to rotate; two forks 201 are connected to the fork frame 2.

[0031] As Figure 2 shown, a linear module 3 is fixedly connected to the side of the fork frame 2 and is connected with a camera assembly 301 through the linear module 3 for adjusting the up and down position of the camera assembly 301 through the linear module 3.

[0032] Specifically, a lighting lamp is installed on the upper side of the fork frame 2 for illuminating towards the front section direction of the forks 201. The camera assembly 301 is located between the two forks 201. By adjusting the position up and down, it is convenient to observe the situation in front of the forks 201 and the position of the forks 201 relative to the pallet through the camera assembly 301, so as to quickly adjust the position of the forks 201 relative to the pallet, so that the forks 201 can be quickly and accurately inserted into the pallet.

[0033] As Figure 3 and 4 shown, there are transition inclined surfaces 202 between the front end faces and the lower surfaces of the two forks 201, and a cover plate 4 is fixedly connected to the position of the transition inclined surface 202; the opposite surfaces of the two forks 201 are both connected with channel bar strips 203 by screws. The cross-sectional shape of the channel bar strip 203 is a "C" - shaped structure, enclosing a cavity with the side surface of the fork 201 for enabling the cable to pass through between the channel bar strip 203 and the side surface of the fork 201, so as to protect the cable by using the channel bar strip 203.

[0034] At the same time, a guide block 204 is fixedly connected to the side of the fork 201 at the end of the channel bar strip 203. The guide block 204 is in a wedge-shaped block structure for preventing the end of the channel bar strip 203 from being impacted. The wedge-shaped block structure enables the guide block 204 to play a certain guiding role when the fork 201 moves forward, avoiding the situation that the channel bar strip 203 is damaged due to direct collision.

[0035] The lower surface of the cover plate 4 is not lower than the lower surface of the fork 201, so that when the lower surface of the fork 201 is close to the ground, there is still a certain distance between the cover plate 4 and the ground, thus effectively preventing the cover plate 4 from being squeezed and collided.

[0036] As Figure 5 and 6As shown, a lighting window 401 is provided on one side of the cover plate 4 facing the front end of the fork 201, and a lighting device is installed inside. Specifically, the bottom wall of the cover plate 4 is arranged parallel to the horizontal plane, and the lighting device is installed on the bottom wall of the cover plate 4 by screws. The lighting device shines toward the front end of the fork 201 through the lighting window 401, so that the light irradiation position is the forward insertion position of the fork 201, thereby facilitating the determination of the insertion position of the fork 201, and realizing the rapid determination of the alignment position of the fork 201 and the cargo pallet. The fork 201 is quickly and accurately inserted into the pallet, so that the convenience of use and production efficiency are effectively improved.

[0037] Example 2

[0038] like Figure 6 and 7 As shown, based on the first embodiment, the outer side of the cover plate 4 is provided with a stepped groove 402 arranged along the edge of the lighting window 401, and is equipped with a transparent cover plate for sealing the lighting window 401. The transparent cover plate can be fixed by gluing or other means, and the transparent cover plate can be organic glass or glass.

[0039] The cover plate 4 has four side walls and is a box structure with an open top, so as to enclose the cover plate 4 and the forks 201 to form a closed space, thereby providing good protection for the internal lighting device.

[0040] In addition, a pad 5 is connected between the cover plate 4 and the fork 201. The cover plate 4 and the pad 5 are directly connected, and the flat surface between the cover plate 4 and the pad 5 can be better controlled during processing, thereby improving the airtightness inside the cover plate 4.

[0041] A camera assembly can also be installed within the cover plate 4, allowing direct observation of the position of the forks 201, allowing for more intuitive and rapid determination of the alignment between the forks 201 and the pallet. The backing plate 5 can also be a metal plate or a rubber sheet. The backing plate 5 has a through hole 501, and the contact surface between the backing plate 5 and the forks 201 has a wire groove 502 connected to the through hole 501. The size of the wire groove 502 is commensurate with the cable passing through it. A sealing ring can also be installed on the cable to squeeze the sealing ring between the wire groove 502 and the forks 201 to achieve a better sealing effect.

[0042] The cables of the lighting device or camera in the cover plate 4 can pass through the through hole 501 and the cable groove 502 and be routed inside the groove strip 203, thereby preventing the cables from being exposed and being accidentally scratched or squeezed. At the same time, the airtightness of the interior of the cover plate 4 can be better ensured, thereby further improving the protection of the lighting device or camera in the cover plate 4.
