Description

Technical Field

[0001] This utility model relates to the technical field of forklifts, and specifically to a forklift fork extension tool. Background Technology

[0002] A forklift is a device used to transfer goods. During the transfer process, it generally uses two forks to lift the goods and then transfer them. However, for cylindrical products, due to their shape, the lifting method is slightly different when using a forklift to transfer them.

[0003] Since cylindrical products cannot be placed horizontally into the container, a forklift with slings is needed to lift the product and then fork it into the container along its length. Because the forklift itself has a limited fork length, additional tooling is usually needed to extend the forks when lifting cylindrical products to meet shipping requirements.

[0004] Currently, most forklift fork extensions are achieved using fork sleeves, which are installed onto the forks to extend their length. However, each fork sleeve corresponds to one fork, so the operator needs to install both sleeves onto the fork beforehand. Furthermore, due to the large width of the two sleeves, it is difficult to quickly find the center of gravity for lifting the product. For cylindrical products, if the lifting point is not the center of gravity, the product is prone to rolling, which not only affects delivery efficiency but also increases the risk of falling. In addition, the flat rectangular structure of the fork sleeve is very easy to deform during lifting. If the top and bottom collide or are squeezed, causing deformation, the fork may not be able to be inserted, rendering the fork sleeve unusable. Utility Model Content

[0005] To address the aforementioned issues—namely, the complexity of installing the extended fork extension sleeve, the difficulty in quickly finding the center of gravity, and the susceptibility to deformation—this invention proposes a forklift fork extension fixture, comprising a primary extension tube with two connecting parts for inserting the fork plate mounted on it.

[0006] A further feature of this invention is that the docking member is provided with a rectangular insertion port, the length of which is set to twice the width of the fork plate.

[0007] A further feature of this invention is that a secondary extension tube is coaxially sleeved at one end of the primary extension tube away from the fork plate, and a threaded hole is provided on the side wall of the primary extension tube. A set screw is threaded into the threaded hole, and one end of the set screw abuts against the secondary extension tube.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This application is easy to install and use, and highly efficient. Simply combine the two forks of the forklift and insert them into the insertion port of the tooling. When lifting with forks, the extension tube contacts the sling, which makes it easier to find the center of gravity during the lifting process.

[0010] 2. The two connecting parts can cooperate more stably with the fork plate, and the two connecting parts are subjected to force at the same time without damaging the fork plate. The first-level extension tube covers the standard products and meets the needs of daily use. The second-level extension tube set at the front end can accommodate some extra-long products.

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] This utility model proposes a forklift fork extension fixture, including a primary extension tube 1 made of 45# steel and heat-treated. A connecting piece 2 for inserting fork plates 5 is fixedly installed on the primary extension tube 1. The connecting piece 2 has an insertion port 21, which is rectangular and its height is equal to the thickness of the fork plate 5. The length of the insertion port 21 is twice the width of the fork plate, so that two fork plates 5 can be inserted into one insertion port 21 when they are joined together.

[0016] There are two docking parts 2, which can make the fork plate 5 more stable.

[0017] The first-stage extension tube 1 is hollow. The second-stage extension tube 3 is coaxially sleeved on the end of the first-stage extension tube 1 away from the fork plate 5. Two sets of threaded holes 11 are opened on the side wall of the first-stage extension tube 1. Each set of threaded holes 11 includes two holes. The two threaded holes 11 in each set are set at 90 degrees along the circumference of the first-stage extension tube 1. A set screw 4 is threaded into the threaded hole 11. One end of the set screw 4 extends into the first-stage extension tube 1 and abuts against the second-stage extension tube 3 to fix and limit the position of the second-stage extension tube 3 relative to the first-stage extension tube 1.

[0018] During installation, first, the two forks 5 of the forklift are joined together, and then inserted into the two insertion ports 21 of the two connecting parts 2 in sequence. Then, the first-stage extension tube 1 can be driven to cooperate with the sling to realize the lifting operation of cylindrical products.

[0019] When it is necessary to lift longer products with a forklift, insert the secondary extension tube 3 into the primary extension tube 1, then adjust the extension length of the secondary extension tube 3, and then use the set screw 4 to limit and fix the secondary extension tube 3, which can meet the needs of lifting longer products with a forklift.

[0020] In summary, this utility model is convenient to install and use, and highly efficient. Simply combine the two forks 5 of the forklift and insert them into the insertion port 21 of the tooling. During lifting, the extension tube contacts the sling, making it easier to accurately locate the lifting center of gravity. The two connecting parts 2 provide a more stable fit with the forks 5, and since both connecting parts bear force simultaneously, they will not damage the forks 5. The primary extension tube 1 covers standard products, meeting daily usage needs, while the secondary extension tube 3 at the front end can accommodate some extra-long products.
