Description

Technical Field

[0001] The utility model relates to a lifting equipment, in particular to a steel pipe stabilizer based on a forklift. Background Art

[0002] As an efficient handling tool, forklifts are widely used in the logistics and warehousing industries. They are usually designed to handle standardized goods, but for non-standardized or special-shaped goods, such as steel pipes, the traditional handling methods of forklifts may have deficiencies in terms of efficiency and safety. Due to the long length and circular cross-section of steel pipes, they are prone to rolling, which poses challenges for forklifts when loading and stacking steel pipe stacks.

[0003] In order to improve the efficiency and safety of handling steel pipes, many beneficial explorations have been carried out in the industry. For example, Chinese Patent CN202880784U discloses a forklift pipe-gripping device, which realizes the stable handling of steel pipes through the cooperation of a lifting mechanism and a forklift guide rod. Specifically, the fork plate descends to the lower part of the stacked steel pipes through the lifting mechanism, and then the forklift moves forward to allow the steel pipes to enter the upper part of the fork plate. Subsequently, the fork plate is lifted by the lifting mechanism, and the steel pipes are firmly fixed between the fork plate and the upper baffle, thereby reducing the mutual collision of the pipe bodies during handling.

[0004] However, the solution proposed in CN202880784U has some significant defects. First, this solution requires major modifications to the original structure of the forklift, which not only increases the modification cost but may also have an adverse impact on the performance of the forklift, reducing its stability and durability. Second, such a modified forklift loses its flexibility and versatility and cannot meet the handling requirements of other types of goods, resulting in a waste of resources and inconvenience in use. Summary of the Utility Model

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0046] Referring to Figure 1-7 As shown, a steel pipe stabilizer based on a forklift has a plurality of screw holes 102 respectively formed in the vertical parts of two forklift forks 101 of the forklift 100. Through the screw holes 102, a set of two steel pipe stabilizers 200 are installed on the two forklift forks 101. Each steel pipe stabilizer 200 includes a fixing plate 201, which is fixed to the vertical part of the forklift fork 101 by cooperating with the screw holes 102 through screws; a guide rail 202, whose longitudinal direction is the same as the longitudinal direction of the vertical part of the forklift fork 101, and is fixed to the fixing plate 201 by screws; a slider 203, which is slidably matched with the guide rail 202; two movable plates 204, which are respectively fixed on both sides of the slider 203; a first oil cylinder 205, whose cylinder body lower end is hinged to the upper end of the fixing plate 201, and whose first piston rod 206 is hinged to the upper ends of the two movable plates 204; a pressing plate 207, whose inner end is hinged to the lower ends of the two movable plates 204; a second oil cylinder 208, whose cylinder body rear end is hinged to the middle parts of the two movable plates 204, and whose second piston rod 209 is hinged to the middle part of the pressing plate 207.

[0047] Preparation before loading: Before starting to load steel pipes, the components of the two steel pipe stabilizers 200 on the forklift, including the first oil cylinder 205 and the second oil cylinder 208, are in their return limit positions. This means that the piston rods 206 and 209 of the oil cylinders are in the most retracted state, preparing for the loading operation.

[0048] Loading steel pipes: When the operator moves the forklift 100 to the position where the steel pipes are stacked and inserts the forklift forks 101 into the bottom of the steel pipe stack, the operator operates the hydraulic system to make the first oil cylinder 205 and the second oil cylinder 208 on the two steel pipe stabilizers 200 extend synchronously, that is, synchronously move out. The piston rods 206 and 209 extend forward, pushing the movable plates 204 to move downward along the guide rail 202 and the pressing plate 207 to turn downward, thereby holding and pressing the steel pipes on the forklift forks 101.

[0049] Transporting steel pipes: Once the steel pipes are firmly supported and fixed by the stabilizers 200, the operator can safely drive the forklift 100 to transport the steel pipes to the designated position.

[0050] Unloading the steel pipe: After arriving at the destination, the operator operates the hydraulic system again, causing the first cylinder 205 and the second cylinder 208 to return synchronously, that is, the piston rods 206 and 209 retract to the limit position. This will release the support and fixation of the steel pipe, and the forklift moves backward so that the steel pipe can be smoothly unloaded from the fork 101.

[0051] Completion of unloading: As the piston rod retracts, the movable plate 204 slides back along the guide rail 202 to the initial position, completing the unloading process, and the forklift 100 can perform the next loading operation.

[0052] The entire working process is precisely controlled by the hydraulic system, achieving safe and stable handling of the steel pipe on the forklift, while maintaining the simplicity of operation and the flexibility of the forklift.

[0053] The first cylinders 205 of the two steel pipe stabilizers 200 move synchronously or asynchronously. In the synchronous motion mode, the two first cylinders 205 extend or retract at the same speed and time. This synchronous control ensures that the steel pipe is evenly supported and fixed on the fork 101, and is suitable for handling steel pipes with consistent dimensions and uniform weight distribution. Synchronous motion can reduce the rolling or sliding of the steel pipe caused by unbalanced forces and improve the stability of handling. In the asynchronous motion mode, the two first cylinders 205 can be independently controlled, allowing them to extend or retract at different speeds or at different time points. This asynchronous control provides greater flexibility and is suitable for handling steel pipes with different dimensions or non-uniform weight distribution. By adjusting the movement of each cylinder 205, the best support can be achieved for different situations. For example, when one end of the steel pipe is large and the other end is small, the first cylinder 205 at the large-end can descend less. Whether it is synchronous or asynchronous motion, the hydraulic system should be equipped with corresponding control mechanisms to ensure the accuracy and responsiveness of the operation. This includes using sensors to monitor the position and pressure of the cylinder 205, and using electronic or mechanical control systems to coordinate the movement of the cylinder 205. In this way, the steel pipe stabilizer 200 can adapt to different handling requirements and improve the efficiency and safety of the forklift 100 when handling steel pipes. These are all conventional technical means in the art and will not be elaborated further.

[0054] Similarly, the second hydraulic cylinders 208 of the two steel pipe stabilizers 200 move synchronously or asynchronously. In the synchronous mode, the two second hydraulic cylinders 208 extend or retract simultaneously, ensuring the consistency of the forces on both ends of the steel pipe during handling. This synchronous operation is particularly suitable for handling steel pipes with a relatively uniform weight distribution over a long length, ensuring the stability of the steel pipe throughout the handling process and reducing the risk of deformation caused by uneven forces. In the asynchronous mode, the second hydraulic cylinders 208 can be independently controlled according to actual needs, allowing them to extend or retract at different speeds or times. This flexibility is particularly important for handling steel pipes with uneven weight distribution or irregular shapes. For example, when one end of the steel pipe is heavier, the stroke of the second hydraulic cylinder 208 at the corresponding end can be increased to provide additional ballast, thereby achieving more precise load balance.

[0055] In another preferred embodiment, a baffle 210 is fixedly connected to the free end of the pressing plate 207, and the lower end of the baffle 210 extends beyond the lower surface of the plate 207. The setting of the baffle 210, especially when its lower end extends beyond the lower surface of the pressing plate 207, can provide an additional support point for the steel pipe, thereby enhancing the stability of the steel pipe during handling. The extended baffle 210 can adapt to steel pipes of different diameters. Especially when the diameter of the steel pipe is large, the baffle 210 can provide better edge support to prevent the steel pipe from rolling or sliding on the forklift fork 101. The presence of the baffle 210 reduces the gap between the steel pipe and the pressing plate 207, reducing the risk of the steel pipe slipping during handling. When handling heavy objects, any slipping or instability may lead to safety accidents. The setting of the baffle 210 improves the safety of the overall structure, ensuring the safety of the operator and the surrounding environment.

[0056] In another preferred embodiment, the first hydraulic cylinders 205 and the second hydraulic cylinders 208 of the two steel pipe stabilizers 200 are floating hydraulic cylinders. A floating hydraulic cylinder is also known as an adaptive hydraulic cylinder, which allows the first hydraulic cylinders 205 and the second hydraulic cylinders 208 to automatically adjust the pressure and the extended length according to the actual weight and size of the steel pipe, thereby achieving more precise and adaptable support. Since the hydraulic cylinders can be automatically adjusted, the operator does not need to manually adjust the extended length of each hydraulic cylinder, which simplifies the operation process and reduces the possibility of operation errors. The floating hydraulic cylinders can ensure that regardless of how the weight of the steel pipe is distributed, the hydraulic cylinders can provide uniform and appropriate supporting forces, avoiding deformation or slipping of the steel pipe caused by uneven stress. During the handling process, the floating hydraulic cylinders can automatically adjust according to the position and pressure of the contact points between the steel pipe and the hydraulic cylinders, optimize the load distribution, and reduce potential damage to the steel pipe or the forklift 100. The automatic adjustment mechanism reduces the workload of the operator, makes the operation easier, improves the work efficiency and the user experience. The design of the floating hydraulic cylinders enables the steel pipe stabilizer 200 to adapt to variable working conditions and steel pipes of different specifications, increasing the versatility and flexibility of the equipment. The automatically adjusted hydraulic cylinders reduce the handling risks caused by improper adjustment and enhance the safety of the entire handling process. Although the floating hydraulic cylinders increase a certain cost, their design usually takes into account the convenience of maintenance, making regular inspection and maintenance easier. It provides an intelligent and efficient solution for the steel pipe stabilizer 200 to meet the requirements for precision and adaptability in modern logistics and industrial applications.

[0057] In another preferred embodiment, the first hydraulic cylinders 205 and the second hydraulic cylinders 208 are driven by the existing hydraulic system of the forklift 100. By using the existing hydraulic system of the forklift, no additional hydraulic unit or power source is required, ensuring perfect compatibility with the forklift 100. It avoids the cost of installing an independent hydraulic system for the stabilizer 200 and reduces the expenses of the overall solution. By using the existing hydraulic system, the design of the steel pipe stabilizer 200 is simplified and the system complexity is reduced.

[0058] In another preferred embodiment, the operating levers for controlling the first hydraulic cylinders 205 and the second hydraulic cylinders 208 are integrated near the lift / lower control lever, tilt control lever, and / or steering control lever in the forklift cab. The integrated design of the operating levers enables centralized operation of all control functions of the forklift in the cab, which not only improves the operation convenience of the forklift when using the steel pipe stabilizer, but also enhances the flexibility and efficiency of the forklift operation, meeting the requirements for an efficient handling tool in modern logistics and industrial applications.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
