Description

Technical Field

[0001] This utility model relates to the field of forks, and more specifically, to an inverted fork that increases lifting height. Background Technology

[0002] In the field of forklift operations, the forks are key components that directly carry goods, and their structural design has a crucial impact on the forklift's operating efficiency, stability, and cargo safety.

[0003] Standard forks typically employ a forward-facing design, with the fork tines extending from the front of the forklift. When goods are initially placed on a pallet at a high position, the lifting mechanism of the forks has a limited height, preventing the standard forks from reaching the pallet and thus hindering their insertion into the pallet's fork holes. This presents a limitation. Furthermore, when picking up goods placed on pallets at higher positions, the high center of gravity of the goods and the fork's inherent structure make it difficult for the standard forks to provide sufficient stability under such conditions. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose an inverted fork that increases the lifting height.

[0005] The technical solution adopted by this utility model to solve its technical problem is: An inverted fork for increasing lifting height includes a first fork section and a second fork section. The limiting lug is welded to the first fork section, and one end of the first fork section forms a first arc section with a main body shape of an isosceles trapezoid. The mounting hole is opened on the second fork portion, and one end of the second fork portion is formed with a second arc portion whose main body shape is an isosceles trapezoid and matches the first arc portion. A bend at an angle of 48-52° to the horizontal plane is formed on the second fork section.

[0006] Furthermore, the first fork section and the second fork section are precisely welded together by a limiting component.

[0007] Furthermore, the limiting assembly includes an ear plate, an insert roller, and a limiting plate. The first fork section and the second fork section are respectively welded with ear plates that are directly opposite each other. The ear plates have ear holes of the same size that are directly opposite each other. Insert rollers are interference-fitted into the ear holes, and a limit plate is welded to one end of the insert rollers.

[0008] Furthermore, the bent portion is provided with several reinforcing ribs.

[0009] Furthermore, a rubber layer is provided on the bearing surface of the second fork.

[0010] Furthermore, both the first and second fork sections are made of high-strength wear-resistant steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Compared to existing technologies, this application can utilize inverted forks for transporting pallets with goods stacked at higher positions. This allows for a further increase in the lifting height of the forks beyond the forklift's maximum lifting height, reducing limitations. At the same time, the inverted forks can provide more stable support for pallets with a higher center of gravity during transport. In summary, this method is more effective for transporting goods pallets. In addition, the independent production of the two fork sections makes it easier to carry out the bending process. After processing, the two parts are accurately connected by the limiting components, and then welded together to carry out subsequent processing operations. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, an inverted fork that increases lifting height includes a first fork section 1 and a second fork section 2 (specifically, both the first fork section 1 and the second fork section 2 are made of high-strength wear-resistant steel). The limiting lug 11 is welded to the first fork portion 1, and one end of the first fork portion 1 forms a first arc portion 12 with a main body shape of an isosceles trapezoid. Mounting hole 21 is provided on the second fork portion 2, and one end of the second fork portion 2 is formed with a second arc portion 22 whose main body shape is an isosceles trapezoid and which cooperates with the first arc portion 12. A bend 23 with an angle of 48-52° to the horizontal plane is formed on the second fork portion 2, preferably with an angle of 50 degrees.

[0014] To accurately align the two fork sections and reduce welding errors caused by positional misalignment during subsequent welding, further optimizations to the above-described embodiments are provided, such as... Figure 2 As shown, the first fork section 1 and the second fork section 2 are precisely welded together by a limiting component; Specifically, the limiting assembly includes ear plate 3, insertion roller 4, and limiting plate 5. Ear plates 3 are welded to the first fork section 1 and the second fork section 2 respectively. Ear holes of the same size and distributed in opposite directions are opened on the ear plates 3 (ear holes are not shown in the figure). Insert rollers 4 are interference-fitted in the ear holes. A limit plate 5 is welded to one end of the insert rollers 4.

[0015] To extend the service life of the inverted forks, further optimizations to the above embodiments are possible, such as... Figure 2 As shown, the bent portion 23 is provided with several reinforcing ribs 6.

[0016] To improve the anti-slip performance and friction of the inverted forks during pallet insertion, further optimizations to the above embodiments are made, such as... Figure 2 As shown, a rubber layer 7 is provided on the bearing surface of the second fork section 2.

[0017] The working process of this utility model: First, the blanks for the first fork section 1 and the second fork section 2 are manufactured and processed separately. Independent production facilitates the processing of the bending section 23. Preferably, the angle between the bending section 23 and the horizontal plane is 50°. After the bending section 23 is processed, the two fork sections are aligned using a limiting component. Once aligned, the top planes of the first arc section 12 and the second arc section 22 are perfectly aligned. Then, the remaining areas are filled and welded. The final welded fork is shown in the attached instruction manual. Figure 2 As shown, this welding method results in a neat appearance and effectively reduces processing errors caused by inaccurate alignment of the two fork sections during the welding process. After the forks are welded together, the limiting lug 11 is then fixedly connected to the fork carriage on the forklift. (The fixing holes on the limiting lug 11 are mainly used to fix the first fork part 1 to the fork carriage of the forklift. By passing fasteners such as bolts through the holes, the forks are firmly installed on the fork carriage to ensure that the forks will not shift during the operation of the forklift and to ensure the stability and safety of the cargo handling operation.) The mounting hole 21 on the second fork section 2 is used to install a pin, so that the second fork section 2 is connected to the lifting mechanism or other related components of the forklift as a rotating pair. In this way, during the operation of the forklift, the forks can rotate around the hole at a certain angle. For example, during the loading and unloading of goods, it is convenient to adjust the tilt angle of the forks to facilitate the picking and placing of goods more smoothly. The inverted forks can then be used for transporting pallets with goods stacked at higher positions. This allows for a further increase in the lifting height of the forks beyond the forklift's maximum lifting height, reducing limitations. At the same time, the inverted forks can provide more stable support for pallets with a higher center of gravity. In summary, this method is more effective for transporting pallets.
