Description

Technical Field

[0001] The utility model relates to a forklift heavy-load container-entering operation fork, which is used for assisting a dock forklift in forking steel coils into containers and belongs to the technical field of dock operation auxiliary tools. Background Art

[0002] Currently, loading and unloading steel coils into containers at docks involves forklifts transporting the coils to the container entrance and loading them into the container. Steel coils typically weigh 10-30 tons, making loading and unloading into containers challenging. Furthermore, the limited length of forklift tines prevents the coils from being fully inserted into the container, failing to meet the requirements for loading steel coils into containers. The lack of suitable loading tools slows loading and unloading, significantly impacting container loading efficiency and potentially damaging the cargo.

[0003] To address these issues, forklift attachments, commonly known as skewer rods, have emerged in the prior art. These attachments primarily consist of a connecting sleeve for connecting to the forklift's tines, and a load-bearing rod for lifting steel coils. While these conventional forklift attachments can provide some assistance, they are inherently heavy and have structural limitations, resulting in a short service life and a tendency to break over time. Utility Model Content

[0004] The utility model aims to solve the various problems mentioned above, and further provide a forklift heavy-load box loading operation fork with scientific and reasonable structural design, stability, reliability and durability.

[0005] In order to solve the above problems, the technical solution adopted by the present utility model is:

[0006] A forklift heavy-load box loading operation fork comprises a fork sleeve and a fork rod. The fork sleeve is used to be plugged and adapted with the fork tines of the forklift, and the fork rod is used to perform the fork picking operation. The special features of the forklift are:

[0007] The fork rod has an integrally formed connecting section and a fork picking section, the connecting section is used to be welded to the fork sleeve, and the fork picking section is used to perform the fork picking operation;

[0008] The connecting section and the fork section of the fork rod are both configured as square steel structures welded from steel plates. Unlike the connecting section, the upper end surface of the fork section is changed from a horizontal surface to an arc surface, which contacts and adapts to the inner ring surface of the steel coil to avoid wear and improve contact stability.

[0009] The fork sleeve includes a pair of frames with the same structure and arranged front and back at a predetermined interval. The middle parts of the two frames are welded to the connecting section of the fork rod, and a pair of fork tooth holes are correspondingly provided on the left and right sides of the two frames.

[0010] Furthermore, the connecting section and the fork section of the fork rod are configured as a hollow square steel structure, and a certain number of reinforcing ribs are welded inside the tube cavity thereof.

[0011] Furthermore, the connecting section and the fork section of the fork rod are configured as solid square steel structures.

[0012] Furthermore, the two frames of the fork sleeve are both configured as square beams, and reinforced square tubes are welded on the left and right sides between the two square beams, and the two reinforced square tubes are respectively located at the outer ends of the two sides of the fork rod connecting section.

[0013] Furthermore, the two frames are flush with the surface of the fork rod connecting section.

[0014] Furthermore, the fork section of the fork rod is marked with corresponding load range values in sections.

[0015] The utility model relates to a forklift for heavy-load box loading operations. The structural design is scientific and reasonable, the operation process is stable and reliable, and the durability and safety of use are effectively extended. First, the fork rod is changed from a traditional round steel tube to a square steel structure, and two options are provided for the specific structural form of the square steel structure: a solid square steel structure or a hollow steel structure with a reinforced plate. Changing to a square steel structure can improve the overall strength and toughness, and the square steel structure with a built-in reinforced plate can reduce weight while ensuring strength and toughness. Secondly, the fork rod is designed with a segmented structure, especially the upper end face of the fork section that contacts the inner ring of the steel coil is set as an arc surface, which can protect the steel coil from wear and increase the stability of the operation process. In addition, square tubes are welded between the square beams of the fork sleeve to further increase the overall strength of the fork, prevent deformation, and enhance stability.

[0019] The present invention is described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] The utility model relates to a forklift heavy-load container loading fork, which is used to assist the forklift in loading and unloading steel coils into and from the container, thereby smoothly completing the container loading and unloading work of steel coils.

[0022] A forklift heavy-load box loading operation fork of this embodiment, such as Figure 1-2 As shown, it is welded together by a fork sleeve 1 and a fork rod 2. The fork sleeve 1 is used to be plugged and adapted with the fork tines of a forklift, and the fork rod 2 is used to fork and pick up steel coils.

[0023] The fork lever 2 comprises a connecting section 21 welded to the fork sleeve 2 and a fork section 22 for fork picking. The connecting section 21 is a hollow square steel structure of predetermined length, welded from steel plates, with a reinforcing rib 23 welded inside. The fork section 22 is a relatively longer hollow square steel structure, welded from steel plates, also welded with a reinforcing rib 23. Its exterior is divided into multiple segments, each labeled with a corresponding load range. Using a square steel structure welded from steel plates as the fork lever not only improves overall strength and toughness, but also significantly reduces weight compared to traditional round steel pipes. Furthermore, to prevent wear on the steel coil from the fork lever and further enhance operational stability, the upper end surface of the fork section 22 is modified from a flat surface to a circular arc surface 22a. This arc surface 22a maintains stable contact with the inner surface of the steel coil, minimizing wear and improving overall stability.

[0024] The fork sleeve 1 is welded to the connecting section 21 of the fork rod 2. It comprises a pair of square beams 11, each of which is identical in structure and spaced apart. The connecting section 21 of the fork rod 2 is welded to the center of the two square beams 11, with the upper end surface of the connecting section 21 flush with the upper surfaces of the two square beams 11. Four ears are formed around the connecting section 21, each with a tine hole 11a to accommodate the tines of a forklift. To enhance the strength of the fork sleeve 1, a reinforcing square tube 12 is welded between the two square beams 11. This reinforced square tube 12 increases the strength of the attachment, prevents deformation and cracking, and enhances overall stability.

[0025] The forklift heavy-load box loading operation fork of this embodiment ensures the overall strength and toughness of the entire operation fork on the basis of weight reduction, effectively avoids breakage, ensures stable and reliable operation process, and increases the service life of the product.
