Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, specifically to a forklift mast. Background Technology
[0002] The forklift mast is the main load-bearing structure of the forklift's lifting mechanism. The lifting mechanism, also known as the mast, can be made in two or more stages depending on the required lifting height. Common forklifts typically use a two-stage mast. Common types include three-stage fully free masts, two-stage fully free masts, and two-stage standard masts. Fully free masts, because they can operate within cargo containers, are often called container masts. Forklifts are frequently used for loading and unloading goods during rail transport.
[0003] When using existing forklift masts, the forks have relatively poor anti-slip properties, which can easily cause goods to fall off, posing a certain safety hazard. In addition, the fork positions of existing forklift masts are relatively fixed, making it inconvenient to use with goods of different sizes, resulting in poor practicality. Utility Model Content

A triangular limiting block 8 is provided at the upper end of the slide rod, and a limiting piece is provided at the end of the connecting slide rod away from the triangular limiting block 8. A first spring 9 is provided on the outer surface of the triangular limiting block 8, and the side of the first spring 9 away from the triangular limiting block 8 is provided on the outer surface of the connecting plate 7. The first spring 9 is sleeved on the outer surface of the connecting slide rod. An installation groove is provided inside the adjustment groove, and a small servo motor 10 is provided inside the installation groove. A control screw 11 is provided at one end of the output shaft of the small servo motor 10, and the control screw 11 is connected to the inside of the connecting plate 7. Triangular limit blocks 8 are slidably connected inside the fork 5. Several triangular limit blocks 8 are evenly distributed on the outer side of the fork 5. A first servo motor 12 is located in the middle of the adjusting frame 3. A first bevel gear 13 is located at one end of the output shaft of the first servo motor 12. A second bevel gear 14 meshes with the outer surface of the first bevel gear 13. A bidirectional screw 15 is located inside the second bevel gear 14. The rotation of the bidirectional screw 15 is connected inside the adjusting frame 3. The support slider 4 is connected to the outer surface of the bidirectional screw 15. A limit rod is located inside the adjusting frame 3. 16. Limiting slide rod 16 is slidably connected inside the support slider 4. Each support slider 4 has several limiting slide rods 16. The connecting slider 2 has a fixed groove inside. A ball 17 is slidably connected inside the fixed groove. A fixed slide rod 18 is set inside the connecting groove. The fixed slide rod 18 is slidably connected inside the connecting slider 2. A second servo motor 19 is set inside the gantry body 1. A transmission screw 20 is set at one end of the output shaft of the second servo motor 19. An adjusting ring 21 is connected to the outer surface of the transmission screw 20.

[0027] To improve the anti-slip properties of the forklift mast and prevent goods from slipping, and to facilitate quick and easy adjustment of the forklift mast's position, thereby enhancing its practicality, as shown in the attached document... Figure 1-6As shown, this application adopts the following structure: through the coordinated arrangement of connecting plate 7, connecting slide rod, first spring 9, triangular limit block 8, small servo motor 10, control screw 11, first servo motor 12, first bevel gear 13, second bevel gear 14, bidirectional screw 15, support slider 4, and limit slide rod 16, during use, by observing the size of the goods, the first servo motor 12 is controlled to rotate, thereby driving the first bevel gear 13 to rotate, which in turn drives the second bevel gear 14 and bidirectional screw 15 to rotate, causing the support slider 4 and forks 5 to slide along the limit slide rod 16, adjusting the distance between the two forks 5 to adapt to the size of the goods. After adjustment, the rotation of the second servo motor 19 drives the transmission screw 20 to rotate, adjusting the height of the forks 5. At the same time, the forklift is controlled to move the forks 5 accordingly. Below the train cargo, a small servo motor 10 rotates, driving the control screw 11 to rotate, which in turn causes the connecting plate 7 to slide along the support slide rod 6, allowing the triangular limit block 8 to protrude above the fork 5. Then, the rotation of the second servo motor 19 drives the transmission screw 20 to rotate, adjusting the height of the fork 5 so that the fork 5 supports the train cargo. At the point where the train cargo contacts the triangular limit block 8, the triangular limit block 8 is compressed, causing it to slide down and compress the first spring 9. At the point where the train cargo contacts the triangular limit block 8, it remains stationary, limiting the cargo and preventing it from slipping off the fork 5. This improves the forklift mast's anti-slip properties, prevents cargo slippage, and allows for convenient and quick adjustment of the fork 5 position, enhancing the forklift mast's practicality.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
