Description

Technical Field

[0001] This utility model relates to the field of material handling, and more specifically, to a forklift device. Background Technology

[0002] In modern warehousing and logistics, telescopic forks, as key components of automated warehousing systems, are widely used for handling and storing goods. Traditional telescopic fork systems typically consist of a Z-axis lifting shaft and a Y-axis telescopic shaft, primarily used for picking up and placing workpieces from conveyor equipment to shelves in fixed positions. However, the limitations of existing telescopic forks are becoming increasingly apparent. These limitations include, but are not limited to: 1. Limited working range: The telescopic shaft of the fork can only move to one side, not both sides. This means that additional equipment or operations are required to pick up or place work on the other side of the shelf. Furthermore, traditional telescopic forks can only operate at preset fixed positions and cannot achieve long-distance horizontal movement; 2. Low shelf utilization: Because telescopic forks cannot cover multiple layers of shelves, the vertical space of the warehouse is underutilized, affecting storage density and capacity; 3. Poor cargo stability: During the movement of the telescopic fork, due to its structure, workpieces are prone to swaying and may even fall during handling. This not only increases the risk of cargo damage but also reduces operational safety. Utility Model Content

[0003] The main objective of this invention is to provide a forklift device to solve the problem of limited operating range of existing forklift devices.

[0004] To achieve the above objectives, according to one aspect of the present invention, a forklift device is provided, comprising: a ground rail assembly, a traveling assembly, a lifting assembly, and a telescopic assembly. The traveling assembly is movably disposed relative to the ground rail assembly and is capable of moving along the extension direction of the ground rail assembly. The lifting assembly is vertically disposed relative to the traveling assembly. The telescopic assembly is retractable relative to the lifting assembly, and the telescopic assembly has a first extension direction and a second extension direction. Both the first extension direction and the second extension direction are angled to the extension direction of the ground rail assembly and the lifting direction of the lifting assembly, and the directions of the first extension direction and the second extension direction are opposite.

[0005] Furthermore, the telescopic assembly includes a first extendable arm and a second extendable arm. The first extendable arm is telescopically connected to the lifting assembly, and the telescopic direction between the first extendable arm and the lifting assembly is along the first extension direction and the second extension direction. The first extendable arm is telescopically connected to the second extendable arm, and the telescopic direction between the first extendable arm and the second extendable arm is along the first extension direction and the second extension direction.

[0006] Furthermore, the lifting assembly and the second extension arm are located on opposite sides of the first extension arm.

[0007] Furthermore, the lifting assembly includes a mounting portion, one of the mounting portion and the first extending arm having a first extending track, the other of the mounting portion and the first extending arm having a first receiving cavity, one of the mounting portion and the first extending arm being able to retract along the first extending track and receive the other in the first receiving cavity; and / or one of the first extending arm and the second extending arm having a second extending track, the other of the first extending arm and the second extending arm having a second receiving cavity, one of the first extending arm and the second extending arm being able to retract along the second extending track and receive the other in the second receiving cavity.

[0008] Furthermore, the telescopic assembly also includes an adsorption element for adsorbing and fixing materials, the adsorption element being located on the second extension arm.

[0009] Furthermore, the walking component has a lifting guide rail, and the lifting component has a lifting slider. The lifting slider is slidably connected to the lifting guide rail, and the lifting slider moves along the lifting guide rail when the lifting component moves up and down relative to the walking component.

[0010] Furthermore, the fork assembly also includes a lifting drive assembly, which includes a lifting transmission component and a lifting drive component. The lifting drive component is connected to the traveling assembly, and the lifting drive component is driven to the lifting assembly through the lifting transmission component. The lifting drive component drives the lifting transmission component to move and drives the lifting assembly to lift.

[0011] Furthermore, the fork unit also has a travel drive assembly, which is driven to connect with the travel assembly and drives the travel assembly to move laterally relative to the ground rail assembly.

[0012] Furthermore, the walking drive assembly includes: a walking drive member and a gear, the walking drive member being driven to connect with the gear, and the ground rail assembly including a rack extending in a horizontal direction, the gear and the rack meshing, the drive member driving the gear to move along the extension direction of the rack, and causing the walking assembly to move laterally.

[0013] Furthermore, the fork assembly also includes a telescopic drive component, which is driven to the telescopic assembly and drives the telescopic assembly to extend along a first extension direction and a second extension direction.

[0014] By applying the technical solution of this utility model, and by setting up a ground rail assembly, a traveling assembly, a lifting assembly, and a telescopic assembly, the fork assembly can move in multiple directions, thereby expanding the working range of the fork assembly and improving its flexibility and adaptability. Specifically, on the one hand, the telescopic assembly has two opposite extension directions, allowing the fork assembly to transport goods from two opposite racks separately, and also to move freely on both sides of the rack, thus widening the travel range of the fork assembly without additional movement, improving work efficiency. Furthermore, the telescopic design reduces the footprint of the fork assembly, facilitating layout. On the other hand, the ground rail assembly and the traveling assembly... The combination of the traveling components, leveraging the length and stability of the ground rail, enables the fork unit to operate over long distances, increasing its working range and adapting to large-span warehouse layouts. It also improves the stability of the fork unit's movement. Furthermore, the lifting component's movement along with the traveling component allows the fork unit to operate efficiently on multi-layer racks without frequent equipment changes. Thus, the fork unit in this embodiment can move in multiple directions—the extension direction of the ground rail, the height direction, the first extension direction, and the second extension direction—significantly expanding its working range, thereby improving work efficiency, reducing operating costs, and offering a simple structure for easy operation.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] To address the problem of limited operating range of existing forklift devices, this invention provides a forklift device.

[0030] like Figures 1 to 8 The forklift device shown includes: a ground rail assembly 10, a traveling assembly 20, a lifting assembly 30, and a telescopic assembly 40. The traveling assembly 20 is movably disposed relative to the ground rail assembly 10 and is capable of moving along the extension direction of the ground rail assembly 10. The lifting assembly 30 is vertically disposed relative to the traveling assembly 20. The telescopic assembly 40 is retractable relative to the lifting assembly 30, and the telescopic assembly 40 has a first extension direction and a second extension direction. Both the first extension direction and the second extension direction are angled to each other with respect to the extension direction of the ground rail assembly 10 and the lifting direction of the lifting assembly 30. The directions of the first extension direction and the second extension direction are opposite.

[0031] This embodiment, by setting up a ground rail assembly 10, a traveling assembly 20, a lifting assembly 30, and a telescopic assembly 40, enables the fork device to move in multiple directions, thereby expanding the working range of the fork device and improving its flexibility and adaptability. Specifically, on the one hand, the telescopic assembly 40 has two opposite extension directions, allowing the fork device to transport goods from two opposite shelves separately and to move freely on both sides of the shelf, thus widening the travel range of the fork device without requiring additional movement, improving work efficiency. Furthermore, the telescopic design reduces the footprint of the fork device, facilitating layout. On the other hand, the ground rail assembly 10 and the traveling assembly 20... The combination of components 20, with the help of the length and stability of the ground rail, enables the fork device to work over long distances, increasing its working range and adapting to large-span warehouse layouts. It also improves the stability of the fork device's movement. Furthermore, the lifting component 30's movement along the traveling component 20 allows the fork device to operate efficiently on multi-layer racks without frequent equipment changes. Thus, the fork device in this embodiment can move in multiple directions—the extension direction of the ground rail, the height direction, the first extension direction, and the second extension direction—greatly expanding its working range, thereby improving work efficiency, reducing operating costs, and offering a simple structure for easy operation.

[0032] It should be noted that, considering the convenience of loading and unloading goods and the stability of the forklift device, the moving directions of the traveling component 20, the moving directions of the lifting component 30, and the telescopic directions of the telescopic component 40 in this embodiment are arranged perpendicularly to each other. The ground rail component 10 extends horizontally, the traveling component 20 can move horizontally and is vertically arranged, the lifting component 30 can rise and fall vertically, and the first and second extension directions of the telescopic component 40 are both horizontal and perpendicular to the extension direction of the ground rail. Of course, according to actual needs, the moving directions of the traveling component 20, the lifting component 30, and the telescopic direction of the telescopic component 40 may not be completely perpendicular to each other. For example, one or more moving directions may be set at an angle to the horizontal or vertical direction, so as to achieve that the moving directions of the traveling component 20, the lifting component 30, and the telescopic direction of the telescopic component 40 are arranged at angles to each other.

[0033] like Figure 7 , Figure 8As shown, in this embodiment, the telescopic component 40 includes a first extending arm 41 and a second extending arm 42. The first extending arm 41 is telescopically connected to the lifting component 30, and the telescopic direction between the first extending arm 41 and the lifting component 30 is along the first extending direction and the second extending direction. The first extending arm 41 and the second extending arm 42 are telescopically connected, and the telescopic direction between the first extending arm 41 and the second extending arm 42 is along the first extending direction and the second extending direction, thereby realizing double and bidirectional stroke of the telescopic component 40, thereby realizing accurate picking and placing of goods at different positions. Specifically, the telescopic component 40 in this embodiment has multiple working states, including three states: only the first extension arm 41 is extended, only the second extension arm 42 is extended, and both the first extension arm 41 and the second extension arm 42 are extended. Each state includes two sub-states: extending along the first extension direction and extending along the second extension direction. In this way, the three states allow the telescopic component 40 to extend to different lengths, and the two sub-states allow the telescopic component 40 to extend in different directions. This enables the telescopic component 40 to pick up and place goods at close range as well as goods at distant locations. Moreover, it can operate on both sides of the shelf and can also pick up and place goods on two opposite shelves, thereby increasing the working range of the fork device and thus improving the applicability of the fork device. At the same time, it can reduce the number of times the fork device moves and improve work efficiency. Optionally, the extension lengths of the first extendable arm 41 and the second extendable arm 42 can be set to be the same or different. When the extension lengths of the first extendable arm 41 and the second extendable arm 42 are the same, the working range of the forklift device is the same whether only the first extendable arm 41 is extended or only the second extendable arm 42 is extended. When the extension lengths of the first extendable arm 41 and the second extendable arm 42 are different, the working range of the forklift device varies depending on the length of the first extendable arm 41 and the second extendable arm 42. Of course, a third extendable arm can also be provided according to actual needs, and the third extendable arm can be telescopically connected to the second extendable arm 42. The telescopic direction between the third extendable arm and the second extendable arm 42 is along the first extension direction and the second extension direction, so that goods at a farther position can be picked up and placed by telescopic assembly 40 without moving other parts of the forklift device, thereby further improving the working range of telescopic assembly 40. When there is a need for operation at a greater distance, a fourth extendable arm, a fifth extendable arm, etc., can be provided with reference to the connection method of the second extendable arm 42 and the third extendable arm.

[0034] In this embodiment, the lifting assembly 30 and the second extension arm 42 are located on opposite sides of the first extension arm 41, which facilitates the stacking of the lifting assembly 30, the first extension arm 41, and the second extension arm 42 when they are in a fully retracted state, avoiding interference with other components, and also facilitating the bidirectional extension and retraction of the telescopic assembly 40. Specifically, in this embodiment, the upper surfaces of the lifting assembly 30, the first extension arm 41, and the second extension arm 42 are arranged sequentially from low to high along the lifting direction of the lifting assembly 30, so that the first extension arm 41 and the second extension arm 42 will not interfere with each other when they retract or extend simultaneously. This also facilitates the carrying of goods on the upper surface of the second extension arm 42, and allows for the convenient placement of other components such as the drive mechanism of the telescopic assembly 40 on the sides or bottom of the lifting assembly 30 and the telescopic assembly 40, ensuring that these components do not interfere with the bidirectional extension and retraction of the telescopic assembly 40, thus ensuring the bidirectional travel of the telescopic assembly 40.

[0035] In this embodiment, the lifting assembly 30 includes a mounting portion 31. One of the mounting portion 31 and the first extension arm 41 has a first extension track 311, and the other of the mounting portion 31 and the first extension arm 41 has a first storage cavity 411. One of the mounting portion 31 and the first extension arm 41 can retract along the first extension track 311 and store the other in the first storage cavity 411. And / or one of the first extension arm 41 and the second extension arm 42 has a second extension track 412, and the other of the first extension arm 41 and the second extension arm 42 has a second storage cavity 421. One of the first extension arm 41 and the second extension arm 42 can retract along the second extension track 412 and store the other in the second storage cavity 421, thereby achieving efficient extension and retraction of the telescopic assembly 40, reducing the space occupied by the telescopic assembly 40, and improving the stability of the fork device when moving. Specifically, in this embodiment, the mounting part 31 is disposed on the top of the lifting assembly 30. The mounting part 31 is provided with a long strip-shaped first extension track 311, which extends along the extension direction of the telescopic assembly 40. The bottom of the first extension arm 41 is provided with a first storage cavity 411, which is configured as a groove extending along the extension direction of the telescopic assembly 40. The length of the groove in the direction perpendicular to the extension direction of the telescopic assembly 40 is not less than the length of the mounting part 31 in the direction perpendicular to the extension direction of the telescopic assembly 40. This allows the first extension track 311 to be embedded in the first storage cavity 411 and to move relative to the first extension track 311 along the extension direction of the telescopic assembly 40. This enables the first extension arm 41 to extend in the first extension direction and the second extension direction, and to stack and store the first extension arm 41 and the mounting part 31. Preferably, to ensure the stability of the relative movement between the first extension arm 41 and the mounting part 31, the first extension track 311 and the first storage cavity 411 can be set to be of equal length in the extension direction of the telescopic assembly 40. Similarly, the bottom of the second extendable arm 42 is provided with a second storage cavity 421, and the top of the first extendable arm 41 is provided with a second extendable track 412. In this embodiment, the second extendable track 412 is the upper surface of the first extendable arm 41. The second extendable track 412 can be embedded in the second storage cavity 421 and can generate relative movement with the second storage cavity 421 along the first and second extendable directions, thereby realizing the bidirectional extension of the second extendable arm 42 and the stacking and storage of the second extendable arm 42 and the first extendable arm 41. Of course, the structural configuration of the mounting part 31, the first extendable arm 41, and the second extendable arm 42 is not limited to this. For example, the top of the mounting part 31 may have a first storage cavity 411, the bottom of the first extendable arm 41 may have a first extendable track 311, the top of the first extendable arm 41 may have a second storage cavity 421, and the bottom of the second extendable arm 42 may have a second extendable track 412, so as to realize the bidirectional double stroke movement of the telescopic component 40.

[0036] In this embodiment, the telescopic assembly 40 further includes an adsorption element 43 for adsorbing and fixing materials. The adsorption element 43 is located on the second extension arm 42, thereby effectively preventing the goods from shaking and falling during handling, thus improving the stability and safety of handling. Specifically, the adsorption element 43 is disposed on the upper surface of the second extension arm 42, with the adsorption surface facing upward, to adsorb the bottom of the goods, which can play a fixing role and prevent the goods from falling during movement. Optionally, the adsorption element 43 can be a vacuum suction cup, which can firmly adsorb various types of goods, while ensuring the safety of the goods even in high-speed movement or complex environments. The forklift device in this embodiment also includes a vacuum generator, and the vacuum suction cup is connected to the vacuum generator through an air pipe.

[0037] like Figure 4 As shown, in this embodiment, the walking component 20 has a lifting guide rail 21, and the lifting component 30 has a lifting slider 32. The lifting slider 32 is slidably connected to the lifting guide rail 21. When the lifting component 30 is raised or lowered relative to the walking component 20, the lifting slider 32 moves along the lifting guide rail 21, thereby playing a guiding role. This ensures the stability and accuracy of the lifting component 30 during movement, avoids vibration or positioning errors of the fork device caused by movement, and improves the operating accuracy of the fork device. This enables accurate positioning of the target location when handling goods on multi-layer shelves. Specifically, in this embodiment, the walking component 20 is configured as a rectangular box, which can be formed by three vertically arranged side panels and a horizontally arranged top panel. A lifting guide rail 21 extending along the height direction is provided on the side of the box surface facing the lifting component 30. The lifting guide rail 21 can be configured as two straight guide rails, which are respectively arranged on the two edges of the box. The lifting slider 32 is embedded in the middle of the lifting guide rail 21. The lifting slider 32 is located on the side of the lifting component 30 close to the walking component 20, and can drive the lifting component 30 to rise and fall along the extension direction of the lifting guide rail 21, thereby realizing the precise handling and placement of goods.

[0038] In this embodiment, the forklift device further includes a lifting drive assembly 50, which includes a lifting transmission component and a lifting drive component. The lifting drive component is connected to the traveling assembly 20 and is driven to the lifting assembly 30 via the lifting transmission component. The lifting drive component drives the lifting transmission component to move and drives the lifting assembly 30 to rise and fall, thereby achieving automatic lifting and falling of the lifting assembly 30 and improving work efficiency. Specifically, the lifting transmission component in this embodiment is equipped with a ball screw structure, which includes a lifting nut and a lifting screw. The lifting nut is connected to the lifting assembly 30, and the lifting screw is connected to the traveling assembly 20 via a ball screw bearing. The lifting nut is sleeved on the lifting screw, so that the drive component of the lifting drive component can drive the lifting screw to rotate, thereby driving the lifting nut to rise and fall, thus achieving the lifting and falling of the lifting assembly 30. With the guiding effect of the lifting guide rail 21, the lifting assembly 30 can achieve stable automatic lifting and falling. The lifting screw can be set in the middle of the housing. When the lifting slider 32 is embedded in the lifting guide rail 21, the lifting nut and the lifting screw can be hidden inside the housing, thereby improving the neatness of the forklift device's appearance. Optionally, a dust cover can be installed to ensure the cleanliness of the ball screw structure. Optionally, the lifting drive component can be a servo motor, cylinder, etc.

[0039] like Figure 5 As shown, in this embodiment, the fork device also has a travel drive component 60, which is driven to connect with the travel component 20 and drives the travel component 20 to move laterally relative to the ground rail component 10. This enables the travel component 20 to achieve a large stroke along the ground rail component 10 and to drive the overall horizontal movement of the lifting component 30 and the telescopic component 40, thereby expanding the range of action of the fork device.

[0040] like Figure 6 As shown, in this embodiment, the walking drive assembly 60 includes: a walking drive component 61 and a gear 62, wherein the walking drive component 61 and the gear 62 are drivenly connected, as shown in the figure. Figure 3As shown, the ground rail assembly 10 includes a rack 11 extending horizontally. A gear 62 meshes with the rack 11. A drive unit drives the gear 62 to move along the extension direction of the rack 11, thereby driving the traveling assembly 20 to move laterally, thus automating the horizontal movement of the forklift device. Specifically, in this embodiment, the traveling assembly 20 is positioned above the ground rail assembly 10. A gear 62 is located at the bottom of the traveling assembly 20, with its axial direction along the height direction. The rack 11 is positioned on one side of the gear 62, with the teeth of the rack 11 facing the gear 62. When the traveling drive unit 61 drives the gear 62 to move along the extension direction of the rack 11, it can drive the traveling assembly 20 to move along the extension direction of the rack 11, thereby realizing the movement of the traveling assembly 20 along the extension direction of the ground rail assembly 10. Optionally, the traveling drive unit 61 can be configured as a servo motor, etc. Of course, the configuration of the walking drive component 60 and the lifting drive component 50 is not limited to the above-mentioned configuration direction. Other methods such as synchronous belts and synchronous pulleys can also be used to achieve the horizontal movement of the walking component 20 and the stable lifting of the lifting component 30.

[0041] The ground rail assembly 10 in this embodiment also includes components such as a linear guide rail, a ground rail groove, a rigid stop, a polyurethane buffer pad, a ground rail tank chain, a planetary reducer, and a motor adjusting block. The linear guide rail is mounted on the ground rail base. The bottom of the walking assembly 20 in this embodiment is provided with a sliding base plate, and the walking drive component 61 is mounted on the sliding base plate. The sliding base plate has a linear guide rail slider. The sliding base plate is mounted on the linear guide rail, and the linear guide rail slider can move along the linear guide rail. The gear 62 of the walking assembly 20 is mounted at the end of the planetary reducer, which is mounted on the sliding base plate. The walking drive component 61 is mounted on the planetary reducer, and the walking drive component 61 drives the gear 62 to rotate through the planetary reducer, thereby driving the walking assembly 20 to move linearly along the rack 11. Optionally, the lifting assembly 30 can also be equipped with a lifting tank chain to ensure the safety of each component.

[0042] In this embodiment, the forklift device further includes a telescopic drive component 70, which is driven to the telescopic assembly 40 and drives the telescopic assembly 40 to extend along a first extension direction and a second extension direction, thereby automating the extension and retraction of the telescopic assembly 40 and improving the flexibility and operating efficiency of the forklift device. Specifically, the telescopic drive component 70 in this embodiment can be fixed on the lifting assembly 30. The same telescopic drive component 70 can be provided for the first extension arm 41 and the second extension arm 42, or separate telescopic drive components 70 can be provided for the first extension arm 41 and the second extension arm 42, as long as bidirectional double-stroke movement of the telescopic assembly 40 can be achieved. Optionally, the telescopic drive component 70 can be configured as a ball screw drive, a synchronous pulley drive, or other similar method.

[0043] The ground rail assembly 10 of this embodiment includes a ground rail base and chemical bolts. The ground rail base with a large stroke is installed on the ground by chemical bolts, thereby extending the working range of the fork device. A lifting assembly 30 with a large stroke is installed above the ground rail base, providing a wide range of lifting strokes for the fork device, which can cover multiple layers of shelves and save space. A telescopic assembly 40 with a bidirectional and double stroke is installed on the lifting assembly 30, which can realize bidirectional and double stroke movement, providing a wide working range for the fork device. A vacuum suction cup is installed on the second extension arm 42, which can adsorb the cartons or transfer boxes to be transported.

[0044] like Figure 1 , Figure 2 As shown, in this embodiment, protective plates are provided on the outside of components such as the ground rail assembly 10, the walking assembly 20, and the lifting assembly 30 to protect the internal components and provide aesthetics. For example, the walking assembly 20 is set as a box, and each panel of the box is a protective plate.

[0045] It should be noted that "multiple" in the above embodiments refers to at least two.
