[0040] Specifically, the fork device is provided with a base frame 10, a first guide seat 20, a first driving unit 30, a bearing seat 40 and a second driving unit 50. The base frame 10 is provided with a supply slide 11, and the supply slide 11 extends in the length direction of the base frame 10. The first guide seat 20 is slidably connected to the supply slide 11 and is provided with a supply slide 21. The first guide seat 20 is connected to the supply slide 11 to achieve stable sliding with the base frame 10. The bearing seat 40 is slidably connected to the supply slide 21 to achieve stable sliding with the first guide seat 20. The fork device can carry goods through the bearing seat 40. The first driving unit 30 is connected to the first guide seat 20. By driving the first guide seat 20 to slide, a primary adjustment of the position of the bearing seat 40 can be achieved. The second driving unit 50 is connected to the bearing seat 40. By driving the bearing seat 40 to slide, a secondary adjustment of the position of the bearing seat 40 can be achieved, thereby enabling the fork device to adapt to the transportation of goods at different distances.

[0041] It can be understood that the number of the base frame 10, the first guide seat 20 and the bearing seat 40 can be adaptively adjusted according to the mass of the goods.

[0042] In this embodiment, Figure 1 As shown, there are two base frames 10 , first guide seats 20 and bearing seats 40 , the two base frames 10 are parallel to each other, the two first guide seats 20 are slidably connected to the two base frames 10 , and the two bearing seats 40 are slidably connected to the two first guide seats 20 .

[0043] It can be understood that the sliding distance between the first guide seat 20 and the bearing seat 40 can be adaptively adjusted according to the position of the cargo, and it is only necessary to enable the bearing seat 40 to move to the side of the cargo by sliding along the first guide seat 20 and the sliding of the first guide seat 20.

[0044] In this embodiment, Figure 1-2 As shown, the first guide seat 20 can extend out of the base frame 10 by sliding along the supply slide groove 11 , and the bearing seat 40 can extend out of the first guide seat 20 by sliding along the supply slide frame 21 .

[0045] In one embodiment, in order to achieve stable sliding of the first guide seat 20 along the slide groove 11, as shown in FIG. Figure 1-3 As shown, side slide grooves 22 are provided on both sides of the first guide seat 20, and the side slide grooves 22 extend in the length direction of the chassis 10. A plurality of first guide blocks 111 are provided on the side walls of the supply slide grooves 11, and each first guide block 111 is arranged at intervals along the length direction of the chassis 10. The first guide seat 20 is slidably connected to some of the first guide blocks 111 through the side slide grooves 22. Specifically, the first guide blocks 111 can provide a limit and guide for the sliding of the first guide seat 20, and through the cooperation between the side slide grooves 22 and the first guide blocks 111, the first guide seat 20 can slide stably relative to the chassis 10, thereby improving the cargo carrying capacity of the fork device.

[0046] In one embodiment, Figure 1-2 As shown, the side wall of the supply slide groove 11 is further provided with a plurality of first guide wheels 112, and each first guide wheel 112 is respectively located between each first guide block 111. Specifically, the first guide wheel 112 can effectively reduce the sliding friction between the first guide seat 20 and the base frame 10 by cooperating with the side slide groove 22, thereby reducing the driving force of the first guide seat 20 during the sliding process, so that the first driving unit 30 can adapt to the driving of the first guide seat 20 under a large load state.

[0047] It can be understood that the driving module 31 can be any driving device such as a hydraulic cylinder that can drive the first guide seat 20 to slide.

[0048] In one embodiment, Figure 1-3 As shown, the first driving unit 30 includes a driving module 31, a first transmission rack 32 and a plurality of transmission gears 33. The transmission gears 33 are sequentially arranged along the length direction of the base frame 10 and are rotatably connected to the base frame 10. Adjacent transmission gears 33 are meshed with each other. The first transmission rack 32 is fixed to the first guide seat 20 and extends in the length direction of the base frame 10. The first transmission rack 32 is meshed with at least part of the transmission gears 33. The driving module 31 is drivingly connected to the transmission gear 33 located at the end, and is used to drive the transmission gear 33 at the end to rotate.

[0049] Specifically, the driving module 31 drives the transmission gear 33 at the end to slide, so that the transmission gear 33 at the end drives all gears to rotate synchronously in the same direction, thereby providing an axial driving force to the first transmission rack 32, and finally driving the first guide seat 20 to slide.

[0050] It can be understood that the driving module 31 can be any driving component such as a single motor device that can drive the transmission gear 33 at the end to rotate.

[0051] In one embodiment, Figure 1 As shown, the driving module 31 includes a driver 311 and a transmission frame 312. The transmission frame 312 is fixed to the transmission gear 33 at the end and extends axially in the width direction of the base frame 10. The driver 311 is connected to the transmission frame 312 to drive the transmission frame 312 to rotate. Specifically, the driver 311 drives the transmission frame 312 to rotate, thereby driving the transmission gear 33 at the end of the base frame 10 to rotate, thereby realizing the driving of the first guide seat 20.

[0052] In this embodiment, Figure 1As shown, the driver 311 includes a motor and a reducer, and two transmission frames 312 are provided. One end of the two transmission frames 312 is connected to the two sides of the reducer, and the other ends of the two transmission frames 312 are respectively connected to the transmission gears 33 located at the ends of the two base frames 10.

[0053] It can be understood that the bearing seat 40 can be any seat structure that can bear goods.

[0054] It can be understood that the second driving unit 50 can be any driving mechanism such as a motor screw module, a hydraulic cylinder, etc. connected to the second guide seat 41 and can drive the bearing seat 40.

[0055] In one embodiment, Figure 1-2 As shown in Figure 4, the bearing seat 40 includes a second guide seat 41, a carrier 42 and a third driving unit 43. The second guide seat 41 is slidably connected to the supply slide 21, and the carrier 42 is slidably connected to the second guide seat 41 along the length direction of the bottom frame 10. The third driving unit 43 is connected to the carrier 42 and is used to drive the carrier 42 to slide. Specifically, the first guide seat 20 realizes a primary adjustment of the position of the carrier 42 by sliding along the supply slide 11, the second guide seat 41 can realize a secondary adjustment of the position of the carrier 42 by sliding along the supply slide 21, and the third driving unit 43 realizes a tertiary adjustment of the position of the carrier 42 by driving the carrier 42 to slide along the second guide seat 41, thereby further improving the cargo range of the carrier 42.

[0056] In one embodiment, Figure 1-3 As shown, a plurality of second guide blocks 211 are provided on both sides of the slide 21, and each second guide block 211 is arranged at intervals along the length direction of the base frame 10, and the second guide seat 41 is slidably connected to some of the second guide blocks 211. Specifically, the second guide block 211 can provide a limit and guide for the sliding of the carrier 42, and through the cooperation between the carrier 42 and the second guide block 211, the stable sliding of the carrier 42 relative to the second guide seat 41 can be achieved, thereby improving the cargo carrying capacity of the fork device.

[0057] In one embodiment, Figure 1-3 As shown, a plurality of second guide wheels 212 are further provided on both sides of the slide 21, and each second guide wheel 212 is respectively located between each second guide block 211. Specifically, the second guide wheels 212 can effectively reduce the sliding friction between the carrier 42 and the second guide seat 41 by cooperating with the carrier 42, thereby reducing the driving force of the carrier 42 during the sliding process, so that the driving device can adapt to the driving of the carrier 42 under a large load state, and improve the cargo carrying capacity of the fork device.

[0058] In one embodiment, Figure 1-3As shown, the second driving unit 50 includes an annular chain 51 and a second transmission rack 52. The second transmission rack 52 is fixed to the first guide seat 20 and extends in the length direction of the chassis 10. The annular chain 51 is sleeved on the second guide seat 41 and meshes with the second transmission rack 52. Specifically, during the sliding process of the first guide seat 20, the second transmission rack 52 will be driven to move synchronously. The annular chain 51 will rotate under the drive of the second transmission rack 52 by meshing with the second transmission rack 52, so that the second transmission rack 52 can drive the second guide seat 41 to slide along the first guide seat 20, and finally drive the carrier 42 to extend. Through the above arrangement of the second driving unit 50, the first guide seat 20 and the second guide seat 41 only need to be driven by the driver 311 to slide.

[0059] It can be understood that the third driving unit 43 can be any driving mechanism such as a motor screw module, a hydraulic cylinder, etc. connected to the carrier 42 and can drive the carrier 42.

[0060] In one embodiment, Figure 1-4 As shown, the third drive unit 43 includes a front drive chain 431, a rear drive chain 432, a front drive sprocket 433 and a rear drive sprocket 434, the front drive sprocket 433 and the rear drive sprocket 434 are respectively rotatably connected to the two ends of the second guide seat 41, the front drive chain 431 and the rear drive chain 432 are staggered, one end of the front drive chain 431 and the rear drive chain 432 is fixed to the first guide seat 20, and the other end of the front drive chain 431 and the rear drive chain 432 are respectively passed around the front drive sprocket 433 and the rear drive sprocket 434 and fixed to the carrier 42.

[0061] Specifically, when the second guide seat 41 slides in the extension direction, the front-drive sprocket 433 will generate a driving force acting on the front-drive chain 431 forward, so that the front-drive chain 431 drives the cargo carrier 42 to extend and protrude from the second guide seat 41; when the second guide seat 41 slides in the retraction direction, the rear-drive sprocket 434 will generate a driving force acting on the rear-drive chain 432 backward, so that the rear-drive chain 432 drives the cargo carrier 42 to retract to the second guide seat 41; through the above setting of the third drive unit 43, the cargo carrier 42, the first guide seat 20 and the second guide seat 41 only need to be driven by the driver 311 to slide.

[0062] In this embodiment, Figure 1-3 As shown, a first chain seat 23 and a second chain seat 24 are respectively fixed to both ends of the first guide seat 20 , an end of the front driving chain is fixed to the first chain seat 23 , and an end of the rear driving chain is fixed to the second chain seat 24 .

[0063] The specific working principle of the fork device provided by the utility model is as follows: the driver 311 drives the transmission frame 312 to rotate, thereby driving each transmission gear 33 to rotate, and the first transmission rack 32 of the first guide seat 20 is meshed with each transmission gear 33, thereby driving the first guide seat 20 to slide through the first transmission rack 32. During the sliding process of the first guide seat 20, the second guide seat 41 will slide in the same sliding direction as the first guide seat 20 driven by the second transmission rack 52. The carrier 42 can slide in the same sliding direction as the second guide seat 41 driven by the front drive sprocket 433 or the rear drive sprocket 434 according to the sliding direction of the second guide seat 41, thereby finally realizing the extension or retraction of the carrier 42 and realizing the carrying of goods at different distances.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
