Description

Technical Field

[0001] This application relates to the field of logistics handling equipment technology, and in particular to a handling device and a handling vehicle. Background Technology

[0002] Traditional forklift-type automated handling systems typically lift the load-bearing wheels first, then insert the forks into the slots of the pallet, and finally lower the load-bearing wheels to lift the pallet.

[0003] However, existing forks usually require a gap on the top and bottom sides when inserted into the slots of a pallet to prevent excessive friction between the forks and the pallet from causing the pallet to move with the forks, affecting the stability during handling. This also means that the forks cannot be used with pallets that have a small slot height. Utility Model Content

[0004] Therefore, it is necessary to provide a handling device and a handling vehicle to address the above problems, so as to improve the adaptability and stability of the handling device.

[0005] This utility model first provides a handling device for handling a pallet, wherein the pallet is provided with a slot, including:

[0006] main body;

[0007] The fork is connected to the main body at one end and can be raised and lowered relative to the main body. The end of the fork away from the main body is used to insert into or pull out of the slot.

[0008] A load-bearing wheel assembly is disposed at the bottom of the fork and is capable of lifting and lowering relative to the fork; and a friction-reducing assembly is disposed on the fork and is capable of moving relative to the fork, the lowest point of the friction-reducing assembly being lower than the lower surface of the fork, so that when the fork is inserted into or removed from the slot, the friction-reducing assembly rolls on the bottom wall of the slot.

[0009] The aforementioned handling device incorporates a friction-reducing component on the forks, with its lowest point below the lower surface of the forks. This allows the component to roll along the bottom wall of the slot when the forks are inserted into or removed from the pallet slot. This rolling contact effectively reduces friction between the forks and the slot wall, preventing the pallet from moving with the forks. Insertion and removal of the forks are smoother, reducing wear on the forks and pallets caused by friction. Furthermore, it significantly reduces the impact force between the forks and the slot during insertion and removal, preventing displacement or tipping risks due to cargo shaking, and significantly improving stability and safety during handling. Additionally, the bottom of the handling device can press against the bottom wall of the slot via the friction-reducing component, requiring only a gap above the forks. This allows the handling device to be used with pallet slots of different sizes, especially those with smaller heights, thus broadening its application range and improving its adaptability.

[0010] In one embodiment, the top of the friction-reducing component is lower than the upper surface of the fork.

[0011] With this configuration, when the forks are carrying a pallet, the upper surface of the forks supports the pallet, while the friction-reducing components do not bear the load. This prevents the friction-reducing components from being deformed by heavy loads and avoids interference between the friction-reducing components and the upper surface of the pallet during the forks' ascent.

[0012] In one embodiment, the friction reduction assembly includes a drive wheel assembly and a drive member. The drive wheel assembly is disposed on the side wall of the fork and is rotatable relative to the fork. The drive member is wound around the drive wheel assembly, and the bottom end of the drive member is lower than the lower surface of the fork.

[0013] This design achieves several advantages. Firstly, the combination of the drive wheel assembly and the drive components enables the rolling motion of the friction-reducing components. Furthermore, the simple structure of the drive wheel assembly and the drive components facilitates production and assembly. Secondly, when the forks press on the pallet, it is the drive components that come into contact with the pallet, not the forks. The pallet is subjected to the pressure of the drive components, which further increases the friction between the pallet and the ground, thus improving stability during handling.

[0014] In one embodiment, the drive wheel assembly includes two drive wheels, which are spaced apart along the length of the fork, and the lower common tangent of the two drive wheels is parallel to the lower surface of the fork.

[0015] With this configuration, the transmission components located below the two transmission wheels are parallel to the bottom wall of the tray slot, ensuring good contact with the bottom wall at all times. This increases the contact area and keeps the transmission components stable during transmission.

[0016] In one embodiment, the conveying device includes a support assembly disposed on the side wall of the forks and located between the two drive wheels, with a portion of the inner surface of the drive member in contact with the support assembly.

[0017] With this configuration, the support components can support and guide the transmission components, preventing them from loosening, deforming, or derailing during operation, thereby ensuring the normal operation of the transmission components and the stability of the entire friction reduction assembly.

[0018] In one embodiment, the surface of the support component is provided with a lubricating layer.

[0019] This design reduces friction between the support components and the transmission components by utilizing a lubrication layer. This makes the friction between the support components and the pallet much less than the friction between the pallet and the ground. The pallet will not move when the forks are inserted or removed, allowing the forks to be inserted and removed smoothly. In addition, the reduced friction between the support components and the transmission components further reduces energy loss and wear, extending the service life of the support components and the transmission components.

[0020] In one embodiment, the support assembly includes a first support rail and a second support rail, both of which extend along the length direction of the fork.

[0021] The inner surface of the transmission component located above the two transmission wheels contacts the first support guide rail, and the inner surface of the transmission component located below the two transmission wheels contacts the second support guide rail.

[0022] With this configuration, the first and second support rails can provide all-round support and guidance for the transmission components, effectively preventing them from twisting or deviating: the first support rail supports the upper part of the transmission components to prevent them from falling; the second support rail bears the reaction force of the pallet on the transmission components after they are pressed on the pallet, preventing the lower part of the transmission components from deforming upwards, thus ensuring the balance and reliability of the support.

[0023] In one embodiment, the support assembly further includes a support sheet metal disposed on the side wall of the fork, and the first support guide rail and the second support guide rail are respectively disposed on both sides of the support sheet metal.

[0024] With this configuration, the support sheet metal can serve as the mounting base for the first and second support rails, providing robust support and transferring the support force to the forks, thereby enhancing the structural strength and stability of the entire support assembly. Furthermore, the connection between the support sheet metal and the side wall of the forks simplifies the installation process and reduces manufacturing costs.

[0025] In one embodiment, the transmission component is a closed-loop chain, a closed-loop belt, or multiple sets of rollers.

[0026] With this configuration, the transmission components are common mass-produced structures that are simple in structure and inexpensive.

[0027] This utility model also provides a transport vehicle, including the aforementioned transport device.

[0028] This design enables traditional pallet trucks to possess low-friction, high-stability, and highly adaptable handling capabilities, significantly improving the overall performance and applicability of pallet trucks and enhancing their value. Attached Figure Description

[0044] Traditional forklift-type automated guided vehicles (AGVs) typically lift the pallet rollers first, then insert the forks into the pallet slots, and finally lower the rollers to raise the pallet. However, existing forks usually require a gap on both the top and bottom sides when inserting into the pallet slots to prevent excessive friction between the forks and the pallet from shifting with the forks, affecting stability during handling. This also makes the forks unsuitable for pallets with small slot heights.

[0045] To solve the above problems, such as Figures 1 to 8 As shown, this utility model provides a handling device and a handling vehicle to improve the adaptability and stability of the handling device in operation.

[0046] like Figure 1 As shown, the length direction of fork 1 is defined as the X-axis direction, the width direction of fork 1 is defined as the Y-axis direction, and the height direction of fork 1 is defined as the Z-axis direction.

[0047] like Figure 1 As shown, this application first provides a conveying device 100. The conveying device 100 includes a main body 5, a fork 1, a load-bearing wheel assembly 2, and a friction-reducing assembly 3. One end of the fork 1 is connected to the main body 5 and is capable of rising and falling relative to the main body 5. The end of the fork 1 away from the main body 5 is used to insert into or remove from a slot 201. The load-bearing wheel assembly 2 is disposed at the bottom of the fork 1 and is capable of rising and falling relative to the fork 1. The friction-reducing assembly 3 is disposed on the fork 1 and is capable of moving relative to the fork 1. The lowest point of the friction-reducing assembly 3 is lower than the lower surface of the fork 1, so that when the fork 1 is inserted into or removed from the slot 201, the friction-reducing assembly 3 rolls on the bottom wall of the slot 201.

[0048] In the conveying device 100 provided by this embodiment of the utility model, a friction-reducing component 3 is provided on the fork 1, and the lowest point of the friction-reducing component 3 is lower than the lower surface of the fork 1. This allows the friction-reducing component 3 to roll on the bottom wall of the slot 201 when the fork 1 is inserted into or removed from the tray slot 201. The rolling contact effectively reduces the friction between the fork 1 and the bottom wall of the slot 201, preventing the tray 200 from moving with the fork 1. The insertion and removal of the fork 1 are smoother, reducing wear on the fork 1 and tray 200 caused by friction. At the same time, it also significantly reduces the friction during insertion and removal. The impact force between the fork 1 and the slot 201 during the pulling process avoids the risk of displacement or overturning of goods due to shaking, significantly improving the stability and safety during handling. Furthermore, the bottom of the handling device 100 can press against the bottom wall of the slot 201 through the friction-reducing component 3, leaving only a gap above the fork 1. This allows the handling device 100 to be used with slots 201 of different specifications of pallets 200, especially slots 201 with smaller height dimensions, thereby broadening the application range of the handling device 100 and improving its adaptability.

[0049] like Figure 1 As shown, the main body 5 can integrate a hydraulic or electric motor driven control system to realize the lifting and lowering movement of the forks 1.

[0050] like Figure 4 As shown, the forks 1 can be made of high-strength materials to withstand the weight of the pallet 200 and the impact load during handling. Furthermore, the shape and size of the forks 1 must match the dimensions of the slots 201 of the pallet 200. Along the height and width directions of the forks 1, the dimensions of the forks 1 are smaller than the dimensions of the slots 201 to ensure that the forks 1 can be smoothly inserted into and removed from the slots 201.

[0051] like Figure 1 As shown, the load-bearing wheel assembly 2 includes a landing gear 22 and load-bearing wheels 21 disposed on the landing gear. The landing gear 22 is disposed at the bottom of the fork 1 and can drive the load-bearing wheels 21 to rise and fall relative to the fork 1. The load-bearing wheels 21 can be made of high-strength, wear-resistant materials, and the rising and falling of the landing gear 22 can be controlled by a hydraulic or electric motor drive system.

[0052] like Figure 1 As shown, the top of the friction-reducing component 3 is lower than the upper surface of the fork 1. When the fork 1 is carrying the pallet 200, the upper surface of the fork 1 supports the pallet 200, while the friction-reducing component 3 does not bear the load. This prevents the friction-reducing component 3 from being deformed by heavy load and avoids interference between the friction-reducing component 3 and the upper surface of the pallet 200 during the upward movement of the fork 1.

[0053] like Figure 1As shown, the friction reduction assembly 3 includes a transmission wheel set 31 and a transmission component 32. The transmission wheel set 31 is disposed on the side wall of the fork 1 and can rotate relative to the fork 1; the transmission component 32 is wound around the transmission wheel set 31, with its lowest point lower than the lower surface of the fork 1. On the one hand, the cooperation between the transmission wheel set 31 and the transmission component 32 realizes the rolling motion of the friction reduction assembly 3, and the structure of the transmission wheel set 31 and the transmission component 32 is simple and easy to manufacture and assemble; on the other hand, when the fork 1 presses on the pallet 200, it is the transmission component 32 that contacts the pallet 200 instead of the fork 1, and the pallet 200 is subjected to the pressure of the transmission component 32, which further increases the friction between the pallet 200 and the ground, improving the stability during the handling process.

[0054] The transmission component 32 can be a closed-loop chain, a closed-loop belt, or multiple sets of rollers to ensure that the friction-reducing component 3 rolls smoothly on the bottom wall of the slot 201. Thus, the transmission component 32 is a common mass-produced structure, simple in design and inexpensive. Furthermore, when the transmission component 32 is a closed-loop chain, rollers can also be provided on the closed-loop chain to further reduce the friction between the transmission component 32 and the slot 201.

[0055] like Figure 3 As shown, in one embodiment, the drive wheel assembly 31 includes two drive wheels 311, which are spaced apart along the length of the fork 1, and the lower common tangent of the two drive wheels 311 is parallel to the lower surface of the fork 1. This ensures that the portion of the drive component 32 located below the two drive wheels 311 is parallel to the bottom wall of the tray 200 slot 201, maintaining good contact with the bottom wall at all times, increasing the contact area, and thus keeping the drive component 32 stable during transmission.

[0056] The size of the drive wheel 311 and the material of the drive component 32 can be selected according to the size and weight of the pallet 200, and the performance of the handling device 100 can be optimized by adjusting the parameters. For example, for a heavier pallet 200, a drive wheel 311 with a larger diameter and a drive component 32 with a more wear-resistant material can be used; for a narrower slot 201, a drive wheel 311 with a smaller diameter and a drive component 32 with a more flexible design can be used.

[0057] Of course, in other embodiments, the number of transmission wheels 311 can also be three, four or more, and the specific number can be selected according to the actual application requirements. This utility model embodiment does not impose specific limitations here.

[0058] In another embodiment, the friction-reducing component 3 can employ spherical rollers or other low-friction roller structures. These roller structures are directly mounted to the bottom of the fork 1 and can rotate relative to the fork 1. The number and arrangement of the rollers can be selected according to actual application requirements. For example, a single row of linearly arranged rollers along the length of the fork 1 can be used, with the roller spacing adjusted as needed to ensure good contact between the rollers and the bottom wall of the slot 201; or a double row of linear rollers can be used, staggered to increase the contact area, thereby providing better support and stability; or a matrix roller arrangement can be used to achieve all-around support and adapt to different shapes of the slot 201 bottom wall. Additionally, for spherical rollers, a dense arrangement can be used to provide uniform support and greater adaptability. The rollers can be rigidly mounted directly to the bottom of the fork 1 via bearings, or elastically connected via springs or pneumatic mechanisms to adapt to unevenness of the slot 201 bottom wall.

[0059] like Figure 1 As shown, the handling device 100 also includes a support assembly 4. The support assembly 4 is disposed on the side wall of the fork 1 and located between the two drive wheels 311, with a portion of the inner surface of the transmission component 32 in contact with the support assembly 4. Specifically, the inner surface of the transmission component 32 refers to the side of the transmission component 32 facing the drive wheel 311 and capable of contacting it, while the outer surface of the transmission component 32 refers to the side of the transmission component 32 away from the drive wheel 311 and capable of contacting the bottom wall of the slot 201.

[0060] like Figure 2 As shown, in one embodiment, the support assembly 4 includes a first support guide rail 41 and a second support guide rail 42, both extending along the length of the fork 1. The inner surface of the portion of the transmission member 32 located above the two drive wheels 311 contacts the first support guide rail 41, and the inner surface of the portion of the transmission member 32 located below the two drive wheels 311 contacts the second support guide rail 42. That is, the upper surface of the first support guide rail 41 contacts the inner surface of the upper transmission member 32, and the lower surface of the second support guide rail 42 contacts the inner surface of the lower transmission member 32. Thus, the first support rail 41 and the second support rail 42 can provide all-round support and guidance for the transmission component 32, effectively preventing it from twisting or deviating; the first support rail 41 supports the upper part of the transmission component 32 to prevent it from falling; the second support rail 42 bears the reaction force of the pallet 200 on the transmission component 32 after it is pressed on the pallet 200, preventing the lower part of the transmission component 32 from deforming upward, thus ensuring the balance and reliability of the support.

[0061] In other embodiments, the support component 4 can be other structures. For example, the support component 4 can be an elastic support structure made of springs, rubber pads or other elastic materials, which can provide flexible support for the transmission component 32, adapt to the slight deformation of the transmission component 32 during the movement, and reduce noise and vibration; the support component 4 can also be a combined support structure, which uses a combination of various materials and structures, such as a combination of springs and dampers, which can provide both flexible support and vibration suppression.

[0062] like Figure 2 As shown, in one embodiment, the support assembly 4 may further include a support sheet metal 43, which is disposed on the side wall of the fork 1. A first support guide rail 41 and a second support guide rail 42 are respectively disposed on both sides of the support sheet metal 43. The support sheet metal 43 serves as the mounting base for the first support guide rail 41 and the second support guide rail 42, providing robust support and transmitting the supporting force to the fork, thereby enhancing the structural strength and stability of the entire support assembly. Furthermore, the connection between the support sheet metal and the side wall of the fork simplifies the installation process and reduces manufacturing costs. The support sheet metal 43 can be flexibly configured according to the arrangement of the transmission component 32 and the transmission wheel 311. For example, the cross-section of the support sheet metal 43 can be L-shaped, U-shaped, or rectangular. The material of the support sheet metal 43 can be high-strength steel plate or aluminum alloy to balance strength and lightweight, and holes are provided for easy installation.

[0063] The first support rail 41 and the second support rail 42 can be bolted to the support sheet metal 43 for easy disassembly and replacement; welded connection can be used to achieve higher strength; or adhesive connection can be used to provide a smoother surface.

[0064] In another embodiment, the first support rail 41 and the second support rail 42 can be directly fixed to the fork 1 by means of bolts, welding, adhesive or other methods without the support sheet metal 43.

[0065] In other embodiments, the support sheet metal 43 may also be integrated with the fork 1 and directly machined on the side wall of the fork 1 to simplify the overall structure of the handling device and improve the adaptability of the handling device 100; or, the support sheet metal 43 may also be connected to the fork 1 through an elastic element to absorb vibration and impact and improve the adaptability of the lifting and handling device 100.

[0066] In one embodiment, the surface of the support component 4 is provided with a lubricating layer. The lubricating layer reduces the friction between the support component 4 and the transmission component 32, making the friction between the support component 4 and the pallet 200 much smaller than the friction between the pallet 200 and the ground. When the forks 1 are inserted into or removed from the pallet 200, the pallet 200 will not move, thus allowing the forks 1 to be inserted into and removed from the pallet 200 smoothly. In addition, the reduction in friction between the support component 4 and the transmission component 32 further reduces energy loss and wear, extending the service life of the support component 4 and the transmission component 32.

[0067] Furthermore, when the support assembly 4 includes a first support rail 41 and a second support rail 42, a lubricating layer is provided on at least the upper surface of the first support rail 41 and the lower surface of the second support rail 42.

[0068] In one embodiment, the first support rail 41 and the second support rail 42 are made of a self-lubricating material, such as polytetrafluoroethylene (PTFE). The smooth surface of the self-lubricating material reduces friction between the first support rail 41 and the second support rail 42 and the transmission component 32, thereby improving the efficiency and lifespan of the entire friction reduction assembly 3.

[0069] In other embodiments, a lubricant may be sprayed onto the surface of the support component 4 to form a lubricating layer.

[0070] In the illustrated implementation, combined with Figures 3 to 8 The working process and principle of the conveying device 100 are as follows:

[0071] like Figure 3 As shown, at this time, the forks 1 are in the raised state, the load-bearing wheel assembly 2 is in contact with the ground, and the handling device 100 can move freely.

[0072] like Figure 4 As shown, when the handling device 100 approaches the pallet 200 to be handled, the control system controls the forks 1 to descend, and the load-bearing wheels 21 gradually retract upward under the control of the landing gear 22, so that the end of the forks 1 away from the main body 5 is aligned with the slot 201 of the pallet 200. "The end of the forks 1 away from the main body 5 is aligned with the slot 201" means that the end of the forks 1 away from the main body 5 is lower than the top wall of the slot 201 of the pallet 200, and the bottom of the friction-reducing component 3 is higher than the bottom wall of the slot 201.

[0073] like Figure 5 As shown, the conveying device 100 slowly advances, inserting the end of the fork 1 away from the main body 5 into the slot 201 of the pallet 200. The insertion distance needs to be adjusted according to the size of the pallet 200. Usually, it only needs to be inserted a certain distance so that the friction-reducing component 3 can contact the bottom wall of the slot 201 before stopping. At this time, the load-bearing wheel 21 continues to retract upward under the control of the landing gear 22.

[0074] like Figure 6 As shown, the forks 1 of the handling device 100 continue to descend, and the load-bearing wheels 21 are fully retracted under the control of the landing gear 22, causing the friction-reducing component 3 located under the forks 1 to press against the bottom wall of the slot 201 of the pallet 200. Due to gravity, the pallet 200 is subjected to a downward pressure, which significantly increases the static friction between the pallet 200 and the ground.

[0075] like Figure 7 As shown, the conveying device 100 continues to be inserted into the slot 201 of the pallet 200. At this time, the friction between the transmission component 32 and the second support guide rail 42, that is, the friction between the transmission component 32 and the bottom wall of the slot 201, is much less than the static friction between the pallet 200 and the ground. Therefore, the pallet 200 will not move, and the friction reduction component 3 rolls smoothly on the bottom wall of the slot 201, allowing the forks 1 to be smoothly inserted into the pallet 200.

[0076] like Figure 8 As shown, in one embodiment, the pallet 200 can be a slotted pallet 200. When the end of the fork 1 away from the main body 5 extends out of the slot 201, the support wheel 21 aligns with the slot of the slotted pallet 200 and can fall to the ground under the control of the landing gear 22. At this time, the control system controls the fork 1 to lift up, and the support wheel assembly 2 supports the weight of the pallet 200, completing the entire insertion process. The process of the fork 1 retracting is completely the opposite of the process of retracting, and will not be described in detail here.

[0077] In another embodiment, the pallet 200 can also be other types of pallets 200, such as a cross-shaped pallet, a double-sided pallet, etc., as long as it has similar slots 201 at its bottom. In this case, the load-bearing wheels 21 can fall to the ground under the control of the landing gear 22 after completely passing through the slots 201. The embodiments of this utility model are not specifically limited here. When handling non-cross-shaped slot pallets 200, the position and size of the friction-reducing component 3 can be adjusted as needed to adapt to the shape and height of different slots 201.

[0078] This utility model also provides a transport vehicle, including the aforementioned transport device 100. This enables the traditional transport vehicle to possess low-friction, high-stability, and highly adaptable transport capabilities, significantly improving the overall performance and applicability of the transport vehicle. Of course, in other embodiments, the transport device 100 can also be used in transport robots, stacker cranes, and various customized transport equipment, thereby greatly expanding the application areas and potential value of this utility model.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above embodiments are merely illustrative of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
