Description
Technical Field
[0001] This invention relates to the field of warehousing and logistics equipment technology, specifically to a forklift with an anti-fall-off structure. Background Technology
[0002] Forklifts are indispensable material handling equipment in warehousing, logistics, and industrial production. In traditional forklift operations, forklifts typically use two parallel forklift arms to lift goods by inserting them into the bottom of wooden pallets. In actual warehousing and logistics transportation, to ensure the overall stability of the container unit, goods are usually tightly bound to the wooden pallet using stretch film, strapping, or other methods, forming a unified structure that is difficult to shift relative to the pallet. The operator precisely controls the forklift arms to insert them into the center of the wooden pallet for lifting. This central support method provides high lateral stability for the goods and pallet, generally preventing them from tipping over or falling.
[0003] However, existing forklifts still pose significant safety hazards during actual handling. When a forklift is loaded with heavy goods, the cantilevered forklift arm, under the pressure of gravity, often experiences slight downward bending deformation. More seriously, when a forklift encounters an emergency requiring braking or deceleration while carrying a load, the cargo and wooden pallet, as a single unit, possess enormous inertia. The static friction between the pallet's bottom surface and the smooth steel forklift arm is often insufficient to counteract the forward thrust generated by this inertia. In this situation, the cargo and pallet can easily accelerate forward along the angle created by the downward bending of the forklift arm, or even slide directly off the front of the forklift arm and fall to the ground. This not only causes severe damage to the cargo but also greatly increases the risk of serious personal injury accidents.
[0004] Currently, conventional forklifts mainly rely on the driver's smooth operation to prevent goods from slipping. They lack a safety mechanism that can automatically trigger and mechanically lock the pallet when goods begin to slide forward, utilizing the goods' own inertia or displacement. Therefore, designing a forklift structure that can automatically prevent further forward sliding of goods in the early stages of slippage has become a pressing technical challenge for those skilled in the art. Summary of the Invention
[0005] Therefore, it is necessary to provide a forklift with an anti-fall structure to address the existing technical problems.
[0006] To address the problems of existing technologies, the present invention adopts the following technical solution: a forklift with an anti-fall structure, comprising a forklift frame and two forklift arms arranged side-by-side and spaced apart on the forklift frame, and further comprising: A cantilever is fixedly mounted on the forklift frame and located between the two forklift arms. The cantilever is parallel to the forklift arms, and the top of the cantilever is at a lower level than the top of the forklift arms. The sliding trigger mechanism includes a guide slider and a floating friction plate. The guide slider is slidably connected to the cantilever along the length of the cantilever. The floating friction plate is located above the guide slider and is slidably connected to the guide slider in the vertical direction. An elastic support is provided between the floating friction plate and the guide slider. In the initial state, the top of the floating friction plate is higher than the top of the forklift arm, so as to contact the bottom surface of the goods and generate frictional force. A locking block is slidably mounted on the cantilever in a vertical direction and located on the sliding path of the guide slider; a wedge-shaped transmission pair is provided between the guide slider and the locking block, the wedge-shaped transmission pair is used to convert the translational sliding of the guide slider caused by the goods into the vertical upward sliding of the locking block, so that the locking block extends upward and prevents the goods from sliding forward; A reset element is disposed between the guide slider and the cantilever, and is used to drive the guide slider to reset backward after the cargo leaves the floating friction plate.
[0007] Furthermore, the locking block, the reset member, and the sliding trigger mechanism constitute an anti-fall component, and the cantilever is provided with a plurality of anti-fall components spaced apart along its length.
[0008] Furthermore, the wedge-shaped transmission pair includes a first inclined surface and a second inclined surface. The first inclined surface is located at the end of the locking block facing the guide slider, and the second inclined surface is located at the end of the guide slider facing the locking block. The first inclined surface and the second inclined surface slide in a wedge-shaped engagement.
[0009] Furthermore, the cantilever is provided with a vertically extending rectangular groove, and the locking block is slidably disposed in the rectangular groove. The periphery of the cantilever is provided with a support frame surrounding the periphery of the rectangular groove. The support frame has a solid sidewall, which is used to provide support for the force-bearing side of the locking block when preventing the goods from sliding forward.
[0010] Furthermore, the locking block has a T-shaped structure that is wider at the top and narrower at the bottom, with its top extending horizontally to both sides to form limiting protrusions. The upper part of the inner wall of the support frame is provided with a relief groove for the limiting protrusions to be accommodated. A limiting step is formed between the relief groove and the support frame for the limiting protrusions to abut downwards, which is used to limit the descent height of the locking block. The top of the locking block has several sharp anti-slip heads distributed in an array at intervals, which are used to pierce into the wooden bracket at the bottom of the goods when the locking block extends upwards.
[0011] Furthermore, a strip-shaped through groove extending along its length is provided on the cantilever, one end of which is connected to the rectangular sliding groove. Guide sliding grooves are provided on the inner walls on both sides of the strip-shaped through groove, and horizontally outwardly extending guide strips are formed on both sides of the guide slider. Each guide strip is slidably disposed in the corresponding guide sliding groove.
[0012] Furthermore, the bottom of the floating friction plate is formed with several guide rods that pass vertically downward through the guide slider. The floating friction plate is slidably connected to the guide slider through the several guide rods, and the top of the floating friction plate is provided with an anti-slip surface.
[0013] Furthermore, the elastic support includes several springs corresponding to the guide rods. Each spring is sleeved on the corresponding guide rod, and both ends of each spring abut against the floating friction plate and the guide slider, respectively. A limiting baffle is provided below the guide slider, and the lower ends of several guide rods pass through the guide slider and are fixedly connected to the limiting baffle.
[0014] Furthermore, the reset element is a tension spring disposed in the strip-shaped through groove. The length direction of the tension spring is parallel to the length direction of the strip-shaped through groove. One end of the tension spring is fixedly connected to the end of the guide slider away from the locking block, and the other end of the tension spring is fixedly connected to the inner wall of the strip-shaped through groove.
[0015] Furthermore, both sides of the bottom of the floating friction plate are formed with downward abutment bars, and the cantilever is provided with a strip-shaped receiving groove extending along its length to accommodate the abutment bars. A buffer pad is provided in the end of the strip-shaped receiving groove near the locking block. In the initial state, the distance between the abutment bars and the buffer pad is greater than the sliding stroke required to drive the locking block to extend upward. The abutment bars are used to abut against the buffer pad to limit the maximum translational sliding stroke of the floating friction plate.
[0016] The beneficial effects of this invention compared to the prior art are: This invention effectively solves the safety hazard of goods easily sliding forward along the bent forklift arms during emergency braking or deceleration of existing forklifts. By adding a cantilever with a top height lower than the forklift arms as a mounting carrier, it does not affect the normal lifting and load-bearing capacity of the forklift arms, and utilizes a floating friction plate with elastic support to closely adhere to the bottom surface of the goods. When the goods tend to slide forward due to inertia, the friction force drives the guide slider to move horizontally, and the wedge-shaped transmission pair instantly converts this horizontal displacement into the vertical upward sliding of the locking block. Thus, in the initial stage of goods sliding, the locking block automatically extends upward to prevent the goods from continuing to slide forward, realizing a purely mechanical anti-fall safety mechanism that is automatically triggered by the goods' own sliding tendency. In addition, with the design of the reset component, the anti-fall structure can automatically retract and reset after the goods are removed, without manual intervention throughout the process. This significantly improves the safety of material handling while ensuring smooth and efficient daily operations. Attached Figure Description

[0019] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0020] refer to Figures 1 to 9 As shown, a forklift with an anti-fall structure is provided. Its basic structure mainly includes a forklift frame 1 and two forklift arms 2 arranged side by side and spaced apart on the forklift frame 1. In order to add an anti-fall function without affecting the normal lifting of goods, the forklift also includes a cantilever 3. The cantilever 3 is fixed on the forklift frame 1 and located between the two forklift arms 2. The cantilever 3 is parallel to the forklift arms 2, and the horizontal plane of the top of the cantilever 3 is lower than the horizontal plane of the top of the forklift arms 2. This height difference design is used to ensure that when the forklift is lifting goods normally, the weight of the goods is mainly borne by the two forklift arms 2, and the cantilever 3 only serves as the mounting carrier of the anti-slip mechanism and does not directly bear the rigid downward impact of the goods.
[0021] It's important to note that in traditional forklift operations, the forklift arm 2 does not directly contact the cargo itself. Instead, it works in conjunction with the wooden pallet supporting the cargo. In actual warehousing and logistics transportation, to ensure the overall stability of the container unit, the cargo is typically tightly bound to the wooden pallet using stretch film, strapping, or other methods, forming a unified structure that is difficult to shift relative to the cargo. To accommodate the forklift arm 2, the bottom of the wooden pallet is equipped with feet to elevate the base, creating an overhead space for the forklift arm 2 to smoothly insert. In actual operation, the operator precisely inserts the forklift arm 2 into the center of the wooden pallet for lifting. This central support method provides high lateral stability for the cargo and pallet, preventing lateral tilting or falling. However, when loading heavy cargo, the front end of the forklift arm 2 often experiences slight downward bending deformation due to the pressure of gravity. More seriously, when the forklift brakes while moving, the cargo and wooden pallet, as a whole, possess significant inertia and are prone to accelerating forward along the angle created by this slight bending. The anti-fall structure added in this invention is designed to prevent such accidental forward slippage.
[0022] To promptly detect unexpected slippage of goods, this invention incorporates a sliding trigger mechanism on the cantilever 3. For example... Figure 3 , Figure 4 and Figure 6As shown, the sliding trigger mechanism includes a guide slider 4 and a floating friction plate 5. The guide slider 4 is slidably connected to the cantilever 3 along its length and serves as a horizontal displacement transmission component. The floating friction plate 5 is positioned above the guide slider 4 and is slidably connected to it in the vertical direction. An elastic support is provided between the floating friction plate 5 and the guide slider 4 to provide an upward supporting force for the floating friction plate 5. In the initial state, the top of the floating friction plate 5 is higher than the top of the forklift arm 2, ensuring that the floating friction plate 5 can closely contact the bottom surface of the goods and generate sufficient frictional force when the goods are lifted by the forklift arm 2.
[0023] To ensure that the aforementioned floating friction plate 5 can float smoothly up and down without shifting, such as Figure 4 and Figure 6 As shown, the bottom of the floating friction plate 5 has several guide rods 18 that extend vertically downwards through the guide slider 4. The floating friction plate 5 is slidably connected to the guide slider 4 via these guide rods 18 to ensure the verticality of the lifting trajectory. Simultaneously, the top of the floating friction plate 5 has an anti-slip surface 19 to further increase the static friction between it and the bottom surface of the cargo. More specifically, the elastic support includes several springs 20 corresponding to the guide rods 18. Each spring 20 is sleeved on its corresponding guide rod 18 to provide uniform support force. Both ends of each spring 20 abut against the floating friction plate 5 and the guide slider 4, respectively. A limiting baffle 21 is provided below the guide slider 4. The lower ends of the guide rods 18 pass through the guide slider 4 and are fixed to the limiting baffle 21 to limit the maximum upward displacement height of the floating friction plate 5 and prevent it from detaching.
[0024] Considering the translational stability of guide slider 4 after being subjected to force and the requirement for subsequent automatic return, such as Figure 6 , Figure 7 and Figure 9 As shown, a strip-shaped groove 15 extending along its length is provided on the cantilever 3, and guide grooves 16 are provided on the inner walls of both sides of the strip-shaped groove 15. Correspondingly, guide strips 17 extending horizontally outward are formed on both sides of the guide slider 4, and each guide strip 17 is slidably disposed in the corresponding guide groove 16 to ensure that the guide slider 4 can only move straight along the length of the cantilever 3. In addition, a reset member is also provided between the guide slider 4 and the cantilever 3. The reset member is used to drive the guide slider 4 to reset backward after the goods leave the floating friction plate 5. The reset member is specifically a tension spring 22 provided in the strip-shaped groove 15. The length direction of the tension spring 22 is parallel to the length direction of the strip-shaped groove 15. One end of the tension spring 22 is fixedly connected to one end of the guide slider 4 away from the locking block 6 that will be subsequently engaged, and the other end of the tension spring 22 is fixedly connected to the inner wall of the strip-shaped groove 15 to accumulate energy when the guide slider 4 moves forward and release it after unloading.
[0025] After the guide slider 4 successfully captures the translational sliding of the goods and generates displacement, in order to convert this translation into an effective locking action, the present invention also includes a locking block 6 and a wedge-shaped transmission pair. For example... Figures 4 to 6 As shown, the locking block 6 is slidably mounted on the cantilever 3 in a vertical direction and is located on the sliding path of the guide slider 4. A wedge-shaped transmission pair is provided between the guide slider 4 and the locking block 6. The wedge-shaped transmission pair is used to convert the translational sliding of the guide slider 4 caused by the goods into the vertical upward sliding of the locking block 6, so that the locking block 6 extends upward and prevents the goods from sliding forward. Specifically, the wedge-shaped transmission pair includes a first inclined surface 8 and a second inclined surface 9. The first inclined surface 8 is located at the end of the locking block 6 facing the guide slider 4, and the second inclined surface 9 is located at the end of the guide slider 4 facing the locking block 6. The first inclined surface 8 and the second inclined surface 9 are wedge-shaped and slide in cooperation to realize the mechanical transmission for direction conversion.
[0026] When faced with extreme conditions such as emergency braking of a forklift, the locking action will be subjected to a huge instantaneous horizontal impact force. Therefore, such as Figure 6 and Figure 7 As shown, one end of the strip-shaped through groove 15 is connected to a vertically extending rectangular slide groove 10 on the cantilever 3, and the locking block 6 is slidably disposed within the rectangular slide groove 10. A support frame 11 surrounds the rectangular slide groove 10 on the periphery of the cantilever 3. The support frame 11 has solid sidewalls to provide robust support and prevent deformation of the force-bearing side of the locking block 6 when preventing goods from sliding forward. Simultaneously, the locking block 6 has a T-shaped structure that is wider at the top and narrower at the bottom. Its top extends horizontally to both sides to form limiting protrusions 12. An clearance groove is provided on the upper part of the inner wall of the support frame 11 to accommodate the limiting protrusions 12. A limiting step 13 is formed between the clearance groove and the support frame 11 for the limiting protrusions 12 to abut downwards, precisely limiting the descent height of the locking block 6. To enhance penetration, such as... Figure 8 As shown, the top of the locking block 6 is arranged in a spaced array with several sharp anti-slip heads 14, which are used to penetrate the wooden bracket at the bottom of the goods to achieve a hard lock when the locking block 6 extends upward.
[0027] It is important to emphasize that, to ensure the smooth operation of this device in daily use and its extreme efficiency during triggering, when the locking block 6 is in its initial descending state, the top of its horizontal plane is strictly lower than the top of the forklift arm 2. This means that, unless a dangerous slip occurs, the locking block 6 will never rub against or interfere with the bottom of the wooden pallet. In the actual passive locking process, thanks to the highly efficient transmission of the wedge-shaped drive pair, the effective upward floating stroke required for the locking block 6 is extremely small, typically maintained within the range of a few millimeters to a few centimeters. That is, as soon as the goods and the wooden pallet exhibit even the slightest forward slippage, the locking block 6 can be instantly and rapidly lifted, using its top anti-slip head 14 to firmly lock the wooden pallet, thus achieving reliable mechanical braking in the initial stage of goods slippage and effectively preventing further forward slippage.
[0028] Furthermore, in actual operation, to prevent the initial sliding inertia of the goods from being too large and causing irreversible damage to the entire mechanical structure, such as... Figure 7 and Figure 9 As shown, both sides of the bottom of the floating friction plate 5 have downwardly formed abutment bars 23. A corresponding strip-shaped receiving groove 24 extending along its length and used to accommodate the abutment bars 23 is provided on the cantilever 3. A buffer pad 25 is provided in the end of the strip-shaped receiving groove 24 near the locking block 6. In the initial state, the distance between the abutment bars 23 and the buffer pad 25 is greater than the sliding stroke required to drive the locking block 6 to extend upward. This clearance design ensures that normal locking action occurs before buffering. Once a violent displacement occurs, the abutment bars 23 abut against the buffer pad 25 to limit the maximum translational sliding stroke of the floating friction plate 5, thus providing end-load overload protection.
[0029] In summary, considering all the above structural designs, to further enhance the safety of full-size cargo, the locking block 6, the reset component, and the sliding trigger mechanism together constitute an anti-fall component 7. In terms of overall layout, the cantilever 3 has several spaced-apart anti-fall components 7 along its length. The overall working logic is as follows: When the forklift lifts the goods, the bottom of the goods presses the floating friction plate 5 downward and compresses the spring 20, and the anti-slip surface 19 is in close contact with the bottom of the goods; when the forklift brakes suddenly, causing the goods to slide forward due to inertia, the friction force forcibly drives the floating friction plate 5 and the guide slider 4 to overcome the elastic force of the tension spring 22 and move forward. The second inclined surface 9 on the guide slider 4 instantly squeezes the first inclined surface 8 on the locking block 6, forcing the locking block 6 to quickly push upward along the rectangular slide groove 10. The anti-slip head 14 at the top of the locking block instantly pierces the wooden bracket at the bottom of the goods, thereby preventing the wooden bracket and the goods from sliding forward; when the goods are unloaded, the floating friction plate 5 bounces up and resets under the action of the spring 20, the guide slider 4 retracts and resets under the tension of the tension spring 22, and the locking block 6 falls back to the limit step 13 under the combined action of its own weight and the retraction of the second inclined surface 9, waiting for the next working cycle.
[0030] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
