Description

Technical Field

[0001] This invention belongs to the field of general vehicle technology, specifically relating to vehicles used for loading, and more particularly to forklift forks and their usage methods. Background Technology

[0002] Forklifts are core equipment used in warehousing and logistics for loading, unloading, stacking, and short-distance transfer of goods. As the operating component of a forklift, the compatibility of the forks with the pallets carrying the goods directly affects the stability of the goods handling process.

[0003] In actual operation, after the forks are inserted into the bottom of the pallet, misalignment and displacement may occur, resulting in unstable support. To improve this problem, existing technologies usually develop special pallets that match the size of the forks. That is, grooves that are adapted to the shape and size of the forks are opened on the bottom of the pallet. During operation, the forks are inserted into the grooves. Generally, the width of the grooves is greater than the width of the forks. By utilizing the structural compatibility between the grooves and the forks, the initial alignment of the support is improved.

[0004] However, in actual working conditions, when the items placed on the pallet are light in weight but large in volume, the contact friction between the upper surface of the forks and the bottom wall of the pallet groove is insufficient to provide enough restraint for the pallet. Especially when the forklift performs dynamic operations such as turning, acceleration and deceleration, relative swaying is likely to occur between the pallet and the forks. This not only reduces the stability of the items on the pallet but may also cause the items to tip over, be damaged, or even pose a safety hazard. It also limits the efficiency and applicability of the forklift in handling light but large items.

[0005] Therefore, how to improve the constraint stability between the forks and the pallet and avoid the pallet from wobbling relative to the forks when the pallet is carrying light-weight but large-volume items has become a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Summary of the Invention

[0007] This disclosure provides at least one forklift frame forklift and its working method.

[0008] In a first aspect, embodiments of this disclosure provide a forklift fork, including:

[0009] At least two forks are slidably mounted on the side wall of the forklift frame;

[0010] An adjustment port is provided on the forks, which is located near the forklift frame;

[0011] An adjustment component is provided inside the adjustment port, and the adjustment component includes:

[0012] The lifting block has its lifting mechanism located inside the adjustment port;

[0013] Two clamping members are slidably disposed within the adjustment port and are adapted to protrude from the side walls of the forks;

[0014] The connecting component has its two ends hinged to the lifting block and the clamping component, respectively.

[0015] When the forks are inserted into the groove at the bottom of the pallet, the lifting block is pressed downward by the top wall of the groove.

[0016] The lifting block pushes the two clamping parts to slide outward synchronously through the connecting parts until the clamping parts abut against the two side walls of the groove.

[0017] In one optional embodiment, the adjustment port is a rectangular through-slot that penetrates the left and right surfaces of the forks;

[0018] In the initial state, the top of the lifting block protrudes from the upper surface of the fork, and the outer wall of the lifting block slides against the inner wall of the adjustment port.

[0019] In one optional embodiment, an adjusting plate is slidably provided on the bottom wall of the lifting block, and the upper ends of the two connecting members are respectively hinged to the bottom wall of the adjusting plate;

[0020] In this process, after any clamping component first comes into contact with one side wall of the groove, the corresponding connecting component pushes the adjusting plate to move horizontally relative to the lifting block, so that the other clamping component, which is positioned opposite to it, comes into contact with the other side wall of the groove.

[0021] In one optional embodiment, the clamping member includes two sliding columns and a connecting rod connecting the two sliding columns, wherein the lower end of the connecting member is hinged to the outer wall of the connecting rod.

[0022] The outer diameter of the sliding column is larger than that of the connecting rod, and the outer wall of the sliding column is provided with an anti-slip layer.

[0023] In one optional embodiment, a guide bar is provided at the outer end of the sliding column;

[0024] The side wall of the adjustment port is provided with a guide groove adapted to the guide bar. An elastic element is provided in the guide groove. One end of the elastic element abuts against the guide bar. The elastic element is adapted to push the sliding column to move into the adjustment port.

[0025] In one optional embodiment, the bottom wall of the lifting block is provided with an adjustment groove along the width direction of the forks, and a return spring is provided at each end of the adjustment groove;

[0026] An adjustment block is provided at the upper end of the adjustment plate. The adjustment block is slidably disposed in the adjustment groove, and both sides of the adjustment block abut against the reset spring.

[0027] In one alternative embodiment, the length of the adjusting block is 1 / 5 to 1 / 4 of the width of the fork.

[0028] In one alternative embodiment, the anti-slip pad layer is made of rubber, and the surface of the anti-slip pad layer is provided with anti-slip texture.

[0029] In one alternative embodiment, a guide surface is provided at the end of the fork away from the forklift frame, the guide surface extending obliquely upward from the lower surface of the fork to the end of the fork.

[0030] Secondly, this disclosure also provides a method for using forklift forks, the method comprising:

[0031] S1: Adjust the relative position of the two forks on the forklift frame according to the spacing of the grooves at the bottom of the pallet, and fix the forks in the preset position by locking the forks;

[0032] S2: Control the forklift to drive the forks to move towards the bottom of the pallet, so that the forks are inserted into the grooves at the bottom of the pallet along the guide surface;

[0033] S3: During the insertion of the forks, the top of the lifting block contacts and is squeezed against the inner top wall of the groove, and slides down along the adjustment port. The lifting block pushes the two clamping parts to slide outward synchronously through the connecting parts until the outer wall of the clamping parts is tightly abutted against the two side walls of the groove, thereby achieving the clamping and fixing of the forks and the pallet.

[0034] In one alternative implementation, in step S2, the depth to which the forks are inserted into the groove is not less than 1 / 2 of the length of the adjustment port, ensuring that the lifting block can be fully squeezed by the top wall inside the groove.

[0035] The beneficial effects of this invention are that it provides forklift forks and their usage method. Through the linkage structure of the lifting block and clamping components, the clamping action is automatically triggered after the forks are inserted into the pallet groove. That is, the lifting block is pushed down by the inner top wall of the groove, and the two clamping components are pushed outward simultaneously to press against the side wall of the groove through the connecting component, forming a mechanical clamping. Combined with the friction constraint between the upper surface of the fork and the inner top wall of the groove, a double fixing effect is formed, which completely solves the problem of relative swaying caused by relying solely on contact friction. Even when the forklift performs dynamic operations such as turning, acceleration, and deceleration, the pallet can remain stably attached to the forks, effectively avoiding the risk of tipping over and being damaged, and greatly improving operational safety.

[0054] Research has found that in actual operation, the forks are prone to misalignment and displacement after being inserted into the bottom of the pallet, resulting in unstable support. To improve this problem, existing technologies usually develop special pallets that match the size of the forks. This involves creating grooves on the bottom of the pallet that are adapted to the shape and size of the forks. During operation, the forks are inserted into these grooves. Generally, the width of the grooves is greater than the width of the forks. By utilizing the structural compatibility between the grooves and the forks, the initial alignment of the support is improved.

[0055] However, in actual working conditions, when the items placed on the pallet are light in weight but large in volume, the contact friction between the upper surface of the forks and the bottom wall of the pallet groove is insufficient to provide enough restraint for the pallet. Especially when the forklift performs dynamic operations such as turning, acceleration and deceleration, relative swaying is likely to occur between the pallet and the forks. This not only reduces the stability of the items on the pallet but may also cause the items to tip over, be damaged, or even pose a safety hazard. It also limits the efficiency and applicability of the forklift in handling light but large items.

[0056] Therefore, how to improve the constraint stability between the forks and the pallet and avoid the pallet from wobbling relative to the forks when the pallet is carrying light-weight but large-volume items has become a technical problem that urgently needs to be solved in this field.

[0057] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.

[0058] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0059] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] like Figure 1 As shown, at least one embodiment provides a forklift fork, including: at least two forks 1 slidably disposed on the side wall of the forklift frame 3; the forklift frame 3 is integrally welded from Q355B alloy steel, and has a portal frame symmetrical structure. Two parallel sliding grooves are machined along the vertical direction on both side walls, and the vertical sections of the forks 1 are adapted to move horizontally within the sliding grooves. A plurality of threaded holes are evenly distributed along the length of the sliding groove sidewalls for use with locking bolts to fix the position of the forks 1, adapting to the requirements of different spacing of the pallet 4 grooves 40.

[0061] like Figure 1 The fork 1 is forged from high-strength alloy steel as a single piece, meeting the heavy-duty operation requirements in the warehousing and logistics field. A sliding block is welded to the end of the fork 1 closest to the forklift frame 3. The size of the sliding block precisely matches the sliding groove of the forklift frame 3. A through hole is provided on the sliding block, corresponding to a threaded hole. A locking bolt passes through the through hole and is threaded into the threaded hole to ensure reliable locking of the fork 1. A guide surface 12 is provided at the end of the fork 1 furthest from the forklift frame 3. This guide surface 12 extends upwards from the lower surface of the fork 1 to the end at an angle of 30°, guiding the fork 1 smoothly into the groove 40 of the pallet 4, preventing jamming during insertion.

[0062] like Figure 3 At a position near the forklift frame 3 on each fork 1 (200mm from the end face of the forklift frame 3), a rectangular through-slot is provided to penetrate the left and right surfaces of the fork 1 as an adjustment port 10. The inner wall of the adjustment port 10 is precision milled to ensure the sliding fit accuracy with the internal adjustment component 2, and the fit clearance is controlled within 0.5-1mm.

[0063] like Figure 3 As shown, the adjustment component 2 includes a lifting block 21, which is vertically disposed within the adjustment port 10. The outer wall of the lifting block 21 slides against the inner wall of the adjustment port 10. In the initial state, the top of the lifting block 21 protrudes from the upper surface of the fork 1, ensuring that the fork 1 can effectively contact the top wall of the groove 40 when inserted into the tray 4. Preferably, a lifting spring is provided on the bottom wall of the adjustment port 10, and the upper end of the lifting spring abuts against the bottom wall of the lifting block 21. The lifting spring can provide a reset force for the lifting block 21 to move upward.

[0064] like Figure 4 The adjusting plate 24 is made of high-strength aluminum alloy, balancing structural strength and lightweight requirements. It is slidably mounted on the bottom wall of the lifting block 21. An adjusting block 240 is welded to the upper end of the adjusting plate 24, slidingly embedded in the adjusting groove 210 on the bottom wall of the lifting block 21. The two sides of the adjusting block 240 abut against the return spring 211. The length of the adjusting block 240 is 25mm, corresponding to 1 / 4.8 of the width of the fork 1 (120mm), falling within the design range of 1 / 5-1 / 4, ensuring sufficient adjustment stroke (±15mm) while avoiding over-adjustment that could affect structural stability. The length of the adjusting plate 24 extends along the width direction of the fork 1, and the length of the adjusting plate 24 is twice the length of the adjusting block 240. In this embodiment, the width of the adjusting plate 24 is greater than the width of the adjusting groove 210.

[0065] like Figure 2 and Figure 3Each adjustment assembly 2 is equipped with two clamping components 23, each consisting of two sliding columns 231 and a connecting rod 232. The sliding columns 231 are made of 45# steel, and the connecting rod 232 is also made of 45# steel. The two ends of the connecting rod 232 are welded and fixed to the inner ends of the two sliding columns 231 respectively, forming a dumbbell-shaped stable structure. The outer diameter of the sliding column 231 is larger than that of the connecting rod 232, and its outer wall is covered with a rubber anti-slip layer. The surface of the anti-slip layer is processed with cross anti-slip texture, which can significantly improve the friction with the side wall of the groove 40 of the tray 4. The outer end of the sliding column 231 is integrally formed with a guide strip. The guide strip has a circular cross section and is set at the axis of the sliding column 231 offset towards the inside of the adjustment port 10. The side wall of the adjustment port 10 has a guide groove 11 adapted to the guide strip. The guide groove 11 has a rectangular cross section. An elastic element with an elastic coefficient of 1.5 N / mm is embedded in the guide groove 11. One end of the elastic element is fixed to the bottom of the guide groove 11, and the other end abuts against the guide bar, which is used to drive the clamping element 23 to reset into the adjustment port 10.

[0066] The connecting piece 22 uses a rigid connecting rod 232 made of No. 45 steel, with one connecting piece 22 corresponding to each clamping piece 23 on each side. The upper end of the connecting piece 22 is hinged to the bottom wall of the adjusting plate 24 by a pin, and the lower end is hinged to the outer wall of the connecting rod 232 of the clamping piece 23 by a pin of the same specification. A brass bushing is fitted at the hinge to reduce friction loss during relative rotation and improve the smoothness of linkage. Specifically, after the fork 1 is inserted into the groove 40 at the bottom of the pallet 4, the lifting block 21 is pressed downward by the top wall of the groove 40; the lifting block 21 pushes the two clamping pieces 23 to slide outward synchronously through the connecting piece 22 until the clamping pieces 23 abut against the two side walls of the groove 40. Through the linkage structure of the lifting block 21 and the clamping member 23, the clamping action is automatically triggered after the fork 1 is inserted into the groove 40 of the pallet 4. That is, the lifting block 21 is squeezed down by the inner top wall of the groove 40, and the two clamping members 23 are pushed outward simultaneously by the connecting member 22 to press against the side wall of the groove 40, forming a mechanical clamping. Combined with the friction constraint between the upper surface of the fork 1 and the inner top wall of the groove 40, a double fixing effect is formed, which completely solves the problem of relative shaking caused by relying solely on contact friction. Even when the forklift performs dynamic operations such as turning, acceleration and deceleration, the pallet 4 can maintain a stable fit with the fork 1, effectively avoiding the risk of items tipping over and being damaged, and greatly improving operational safety.

[0067] At least one embodiment provides a method of using forklift forks, the method comprising:

[0068] S1: Adjust the relative position of the two forks 1 on the forklift frame 3 according to the spacing of the grooves 40 at the bottom of the pallet 4, and fix the forks 1 in the preset position by locking the locking parts;

[0069] S2: Control the forklift to drive the forks 1 to move towards the bottom of the pallet 4, so that the forks 1 are inserted into the groove 40 at the bottom of the pallet 4 along the guide surface 12;

[0070] S3: As Figure 6 During the insertion of the fork 1, the top of the lifting block 21 contacts and is squeezed against the inner top wall of the groove 40, and slides down along the adjustment port 10. The lifting block 21 pushes the two clamping parts 23 to slide outward synchronously through the connector 22 until the outer wall of the clamping part 23 is tightly abutted against the two side walls of the groove 40, thereby achieving the clamping and fixing of the fork 1 and the pallet 4.

[0071] In step S2, the depth to which the fork 1 is inserted into the groove 40 is not less than 1 / 2 of the length of the adjustment port 10, ensuring that the lifting block 21 can be fully squeezed by the inner top wall of the groove 40.

[0072] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0073] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0074] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
