Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, and more specifically, to a forklift frame structure. Background Technology

[0002] Traditionally, forklifts were mostly fuel-powered. While fuel-powered forklifts still hold an important position in outdoor work environments due to their powerful engines and long range, their high noise and emissions not only pollute the environment but also limit their use indoors or in environments with high environmental requirements. With the advancement of national environmental protection policies and the development of new energy technologies and automated logistics, electric automated guided vehicles (AGVs), with their zero emissions and low noise characteristics, help improve the working environment, reduce potential threats to employee health, and comply with increasingly stringent environmental regulations. Currently, there is strong market demand for AAVs, with requirements for short delivery times and low prices.

[0003] Existing forklift frames have a large number of components, resulting in a large workload for material preparation and processing, and consequently, long delivery cycles that do not meet market demands. With the continuous rise in raw material costs, the cost pressure on electric automated guided forklifts is further increasing, and product profits are shrinking. Therefore, it is necessary to develop new forklift frames to overcome the above-mentioned shortcomings, thereby reducing construction costs, improving construction efficiency, and shortening delivery cycles. Utility Model Content

[0004] The purpose of this utility model is to provide a forklift frame structure that allows material to be cut into the middle part of the fork legs by setting a counterweight size. The size of the opening groove set in the middle of the counterweight can directly cut out the size of the fork leg tip, thereby maximizing the material utilization rate.

[0005] This utility model is achieved through the following technical solution: A forklift frame structure includes a chassis assembly and a frame assembly. The chassis assembly includes an integrally formed fork leg with a load-bearing wheel vertical plate connected to the front end of the fork leg. The front end of the load-bearing wheel vertical plate is provided with a fork leg tip. The frame assembly includes a counterweight. The plate thickness of the counterweight, fork legs, and fork leg tips is the same. The counterweight has an opening groove with a size greater than or equal to the size of the fork leg tip. The opening size between the two fork legs is greater than or equal to the size of the counterweight. The counterweight, fork legs, and fork leg tips can be designed to be cut together to minimize waste.

[0006] Furthermore, the frame assembly also includes a left side panel and a right side panel, with a gantry mounting plate welded to the middle front end of the left side panel and the right side panel, a drive mounting plate welded to the middle rear end of the left side panel and the right side panel, a caster mounting plate welded to the rear end between the left side panel, the right side panel and the drive mounting plate, and a counterweight welded to the middle of the left side panel, the right side panel, the gantry mounting plate and the drive mounting plate.

[0007] Furthermore, the chassis assembly also includes a cylinder support plate, which is symmetrically welded to both sides of the fork legs and the mast mounting plate.

[0008] Furthermore, the front of the fork leg is provided with a notch, and the load-bearing wheel vertical plate is welded to the fork leg through the notch to ensure the welding strength between the fork leg and the load-bearing wheel vertical plate, thereby ensuring the overall strength of the forklift.

[0009] Furthermore, the front end of the fork tip is rounded to reduce sharp corner injuries during forklift operation.

[0010] Furthermore, the rear end of the fork tip is provided with a bevel, and the bearing wheel vertical plate is welded to the fork tip through the bevel. A plug welding and grinding process can be performed to ensure aesthetics and strength.

[0011] Furthermore, the longitudinal dimension of the bearing wheel vertical plate is consistent with the plate thickness of the fork leg, reducing welding measurement work and allowing for flush welding.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the counterweight size, material can be cut into the middle part of the fork leg. The size of the opening slot set in the middle of the counterweight can directly cut out the size of the fork leg tip, which can maximize the material utilization rate.

[0013] 2. The fork legs are cut from a single piece of plate, which saves time, improves precision, and increases strength compared to welding multiple plates.

[0014] 3. The fork legs have notches at the front to allow for overlapping welding of the load-bearing wheel vertical plates, ensuring the welding strength between the fork legs and the load-bearing wheel vertical plates, thereby ensuring the overall strength of the forklift.

[0015] 4. The front of the forklift legs is rounded to reduce sharp corner injuries during forklift operation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 – Figure 3 As shown in Embodiment 1, a forklift frame structure includes a chassis assembly 1 and a frame assembly 6. The chassis assembly 1 includes a one-piece fork leg 2, which saves time, has better precision, and is stronger than welding multiple plates. The front end of the fork leg 2 is connected to a load-bearing wheel vertical plate 3, and the front end of the load-bearing wheel vertical plate 3 is provided with a fork leg tip 4. The frame assembly 6 includes a counterweight 10. The plate thickness of the counterweight 10, fork leg 2, and fork leg tip 4 is the same. The counterweight 10 is provided with an opening groove 11, the size of which is greater than or equal to the size of the fork leg tip 4. The opening size between the two forks of the fork leg 2 is greater than or equal to the size of the counterweight 10. The counterweight 10, fork leg 2, and fork leg tip 4 can be designed to be cut together, achieving the goal of minimizing waste. Example 2: A forklift frame structure, wherein the frame assembly 6 further includes a left side panel 8 and a right side panel 9, a mast mounting plate 7 is welded to the middle front end of the left side panel 8 and the right side panel 9, a drive mounting plate 12 is welded to the middle rear end of the left side panel 8 and the right side panel 9, a caster mounting plate 13 is welded to the rear end between the left side panel 8, the right side panel 9 and the drive mounting plate 12, and a counterweight 10 is welded to the middle of the left side panel 8, the right side panel 9, the mast mounting plate 7 and the drive mounting plate 12; the chassis assembly 1 further includes a hydraulic cylinder support plate 5, which is symmetrically welded to the fork legs 2 and the mast mounting plate 12. The fork legs 2 have notches on both sides of the plate 7. The vertical plate 3 of the bearing wheel is welded to the fork legs 2 through the notches to ensure the welding strength between the fork legs 2 and the vertical plate 3 of the bearing wheel, thereby ensuring the overall strength of the forklift. The front end of the fork leg tip 4 is rounded to reduce sharp corner injuries during forklift operation. The rear end of the fork leg tip 4 is beveled. The vertical plate 3 of the bearing wheel is welded to the fork leg tip 4 through the bevel. A plug welding and grinding process can be performed to ensure aesthetics and strength. The longitudinal dimension of the vertical plate 3 of the bearing wheel is consistent with the plate thickness of the fork legs 2, reducing welding measurement work. Flush welding is sufficient. Other aspects are the same as in Embodiment 1.

[0020] like Figure 4 As shown, by setting the size of the counterweight 10, material can be cut into the middle part of the fork leg 2, which can maximize the material utilization rate. The size of the opening slot 11 set in the middle of the counterweight 10 can directly cut out the size of the fork leg tip 4, which can maximize the material utilization rate.
