Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a heavy-duty forklift fork carriage rubber hose motion guide rail. Background Technology

[0002] Heavy-duty forklifts are industrial vehicles specifically designed for handling oversized and overweight goods. They typically have a rated load of 10 tons or more, with a maximum load of 50 tons or even higher. They are widely used in ports, steel mills, heavy manufacturing industries, and large-scale warehousing and logistics.

[0003] The load stabilizer mounted on the fork carriage of a heavy-duty forklift is a key component that ensures the stability and safety of the forklift when handling heavy objects. It suppresses the lateral sway of the fork carriage through hydraulic or mechanical devices, preventing tipping caused by load imbalance. At the same time, it absorbs the impact from lifting or uneven road surfaces, protecting the goods and the forklift structure. It can also automatically adjust the level of the forks when operating on sloping roads to prevent the goods from slipping.

[0004] However, when a load stabilizer is installed on the fork carriage of a heavy-duty forklift, the load stabilizer moves laterally on the fork carriage. The hydraulic hose between the clamping arm drive cylinder and the fork carriage lacks effective motion guidance, making it prone to interference and cuts. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of interference and easy cutting of the hydraulic hose between the clamping arm drive cylinder of the load stabilizer and the forklift fork carriage in the existing technology. It provides a heavy-duty forklift fork carriage hose movement guide rail. This heavy-duty forklift fork carriage hose movement guide rail has a simple structure, is easy and quick to install and disassemble, and can effectively avoid the problems of interference and cutting of hydraulic hose after the load stabilizer is installed on the forklift, thus ensuring the service life of the hydraulic hose and the normal operation of the forklift.

[0006] To achieve the above objectives, this utility model provides a heavy-duty forklift fork carriage hose movement guide rail. This heavy-duty forklift fork carriage hose movement guide rail includes a vertical plate and a curved plate arranged side-by-side. The tops of the vertical and curved plates cooperate to form guide grooves, and the middle and bottom sections form guide grooves for accommodating hoses. Furthermore, the upper opening width of the guide groove is greater than the bottom width, and the bottom opening width is greater than the outer diameter of the hose. A guide rail mounting plate extends from the bottom of the vertical plate, and the guide rail mounting plate has multiple mounting holes for mounting the guide rail. A pipe clamp mounting plate extends outward from the side of the vertical plate to install pipe clamps and fix the hose. Anti-cut hose assemblies are provided at the edges of the guide grooves to protect against impacts, compression, and cuts.

[0007] Preferably, the cut-resistant pipe assembly includes a first cut-resistant steel pipe arranged circumferentially around the top edge of the vertical plate and a second cut-resistant steel pipe arranged circumferentially around the top edge of the curved plate.

[0008] Preferably, the first anti-cut steel pipe is made by bending a steel pipe and welding it to the vertical plate, and the second anti-cut steel pipe is made by bending a steel pipe and welding it to the curved plate.

[0009] Preferably, the bottom of the guide groove is provided with a cut-resistant round steel bar located between the first cut-resistant steel pipe and the second cut-resistant steel pipe.

[0010] Preferably, the cut-resistant round steel is machined from round steel and its two ends are welded and fixed to the vertical plate and the curved plate, respectively.

[0011] Preferably, the heavy-duty forklift fork carriage hose motion guide rail also includes stiffening plates, with both ends of the stiffening plates welded and fixed to the bending plate and the guide rail mounting plate, respectively.

[0012] Preferably, there are multiple stiffeners that are evenly distributed along the length of the vertical plate 4.

[0013] Preferably, the stiffening plate forms a 45° angle with the bending plate and the guide rail mounting plate.

[0014] According to the above technical solution, guide grooves are formed at the top of the vertical plate and the curved plate, and guide slots for accommodating the hose are formed in the middle and bottom. The upper opening width of the guide slot is greater than the bottom width, and the bottom opening width is greater than the outer diameter of the hose. At this point, the main structure of the guide rail is formed, and it can be fixed to the fork carriage by bolts through the mounting holes on the guide rail mounting plate, making installation and disassembly convenient and quick. Because the guide groove of the guide rail is wider at the top and narrower at the bottom, the wider upper opening facilitates the entry of the hose, while the bottom of the guide groove, which is slightly larger than the outer diameter of the hose, effectively constrains the hose. Thus, only one end of the hose needs to be fixed with a hose clamp mounted on the hose clamp mounting plate, and the other end can be constrained within the guide groove of the guide rail. The guide rail provides a certain degree of protection for the hose, preventing it from being impacted or squeezed. Furthermore, an anti-cut tube assembly is provided at the edge of the guide groove, which can prevent the hose from being cut during movement, making the operation of the clamping arm drive cylinder of the load stabilizer safer and more reliable.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "top," "middle," and "bottom" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0027] See Figures 1 to 4 This utility model provides a heavy-duty forklift fork carriage hose movement guide rail, which includes a vertical plate 4 and a curved plate 5 arranged side by side. The top of the vertical plate 4 and the curved plate 5 are fitted together to form a guide groove, and the middle and bottom are formed with guide grooves to accommodate the hose 10. The upper opening width of the guide groove is greater than the bottom width, and the bottom opening width is greater than the outer diameter of the hose 10. The bottom of the vertical plate 4 extends to form a guide rail mounting plate, and the guide rail mounting plate has a plurality of mounting holes for mounting guide rails 9. The side part of the vertical plate 4 extends outward to form a pipe clamp mounting plate 6 for mounting pipe clamps and fixing the hose 10. The edges of the guide grooves are provided with anti-cut pipe assemblies to prevent the hose 10 from being hit, squeezed and cut.

[0028] Through the above technical solution, a guide groove is formed at the top of the vertical plate 4 and the curved plate 5, and guide grooves for accommodating the rubber tube are formed in the middle and bottom. The upper opening width of the guide groove is greater than the bottom width, and the bottom opening width is greater than the outer diameter of the rubber tube 10. At this point, the main structure of the guide rail is formed, and it can be fixed to the fork carriage by bolts through the mounting holes opened on the guide rail mounting plate, making installation and disassembly convenient and quick. Since the guide groove of the guide rail 9 is wider at the top and narrower at the bottom, the wider upper part of the groove facilitates the entry of the rubber tube 10, while the bottom of the guide groove, which is slightly larger than the outer diameter of the rubber tube 10, can effectively constrain the rubber tube 10. In this way, only one end of the rubber tube 10 needs to be fixed with a pipe clamp installed on the pipe clamp mounting plate 6, and the other end can be constrained to move within the guide groove of the guide rail 9. The guide rail 9 can play a certain protective role for the rubber tube 10, preventing the rubber tube 10 from being impacted and squeezed. Furthermore, an anti-cut tube assembly is provided at the edge of the guide groove, which can prevent the hose 10 from being cut during movement, making the operation of the clamping arm drive cylinder of the load stabilizer safer and more reliable.

[0029] In this embodiment, in order for the heavy-duty forklift fork carriage hose movement guide rail to provide sufficient protection for the hose 10 inside the guide rail 9, the cut-resistant tube assembly needs to provide sufficient mechanical strength to maintain its structural integrity even in the event of collision, compression, or even cutting with sharp edges on the fork carriage 8. Preferably, the cut-resistant tube assembly includes a first cut-resistant steel tube 1 arranged circumferentially around the top edge of the vertical plate 4 and a second cut-resistant steel tube 2 arranged circumferentially around the top edge of the curved plate 5. In this way, in addition to the protection provided by the vertical plate 4 and the curved plate 5, the first cut-resistant steel tube 1 and the second cut-resistant steel tube 2 further enhance the mechanical strength of the guide rail 9, preventing it from easily deforming or breaking when subjected to collision, compression, and cutting, ensuring the structural integrity of the hose 10, greatly extending the service life of the hose 10, and saving maintenance costs.

[0030] In the actual manufacturing and material selection process of the aforementioned cut-resistant steel pipes, the preferred method is to use the first cut-resistant steel pipe 1, which is made by bending and welding a steel pipe and then fixing it to the vertical plate 4. The second cut-resistant steel pipe 2 is made by bending and welding a steel pipe and then fixing it to the bending plate 5. The steel pipe is made of hard material and still has strong anti-damage capabilities even after bending. In addition, the bends also form a smooth surface, which can prevent injuries or cuts when manually disassembling the guide rail 9, thus ensuring the health and safety of the operators.

[0031] Furthermore, in order to expand the protection range of the cut-resistant pipe assembly and achieve all-round, three-dimensional protection for the hose 10, it is preferable to install a cut-resistant round steel bar 3 at the bottom of the guide groove, between the first cut-resistant steel pipe 1 and the second cut-resistant steel pipe 2. In this way, the cut-resistant round steel bar 3, together with the first cut-resistant steel pipe 1 and the second cut-resistant steel pipe 2, protects all areas on the guide groove that may come into contact with the fork carriage 8, resulting in greater protection strength, wider range, and better effect.

[0032] When setting the aforementioned cut-resistant round steel bar 3, in order to improve the structural compactness of the guide groove and prevent it from easily deforming under large external forces, it is preferable that the cut-resistant round steel bar 3 is made by turning round steel and its two ends are welded and fixed to the vertical plate 4 and the curved plate 5 respectively. With this structure, through the connection and protection of the cut-resistant round steel bar 3, the mechanical strength of the guide groove is further improved and its stability is better.

[0033] Similarly, to improve the structural rigidity of the heavy-duty forklift fork carriage hose guide rail, the heavy-duty forklift fork carriage hose guide rail preferably also includes stiffening plates 7, with both ends of the stiffening plates 7 welded and fixed to the bent plate 5 and the guide rail mounting plate, respectively. In this way, through the pulling and traction action of the two ends of the stiffening plates 7, the connection between the bent plate 5 and the guide rail mounting plate bracket is made more stable, and the mechanical structure of the guide groove is further strengthened.

[0034] Specifically, when the guide rail 9 is relatively long, in order to ensure that the stiffening plates 7 provide sufficient and comprehensive structural rigidity enhancement, it is preferable to use multiple stiffening plates 7 evenly distributed along the length of the vertical plate 4. In this way, the evenly distributed multiple stiffening plates 7 can provide comprehensive and average support and traction force, ensuring the stability of the bent plate 5 and the guide rail mounting plate bracket after connection.

[0035] Furthermore, the aforementioned stiffener 7 can form a right-angled triangle or approximately right-angled triangle structure, which forms a 45° angle with both the curved plate 5 and the guide rail mounting plate. This structure makes the interaction force between the stiffener 7 and the two more even, ensuring the balance of forces while improving the compactness of the structure.

[0036] Furthermore, considering the operating environment of the heavy-duty forklift fork carriage hose guide rail, it is preferable to apply paint to the formed structure after welding to increase rust resistance and ensure the effectiveness of protection and the service life of the heavy-duty forklift fork carriage hose guide rail.

[0037] In summary, this heavy-duty forklift fork carriage hose motion guide effectively solves the problems of hydraulic hose interference and wear caused by the installation of load stabilizers on heavy-duty forklifts, while also ensuring convenient installation and disassembly, and is safe and reliable.

[0038] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
