AI Technical Summary
The forks on the loading platform of existing heavy stacker cranes have a short extension distance, which makes it difficult to stably transport goods, and they lack a limiting mechanism, resulting in insufficient stability of goods during the handling process.
A high-efficiency cargo handling structure for a heavy-duty stacker crane was designed. The structure uses a hydraulic rod to drive the forks to move along the track groove. The sliding connection between the limiting post and the limiting groove increases the extension distance of the forks. A servo motor drives the vertical threaded rod to rotate, and the threaded connection drives the top pressure plate to move vertically, thereby vertically squeezing and positioning the cargo.
It improves the stability and extension distance of the forks, and effectively protects the goods through the limiting mechanism, ensuring the stability and safety of the goods during the handling process.

[0024] In this example, the track groove 2 and the forklift forks 3 are symmetrically distributed about the center of the load-carrying platform 1. The top surface of the forklift forks 3 is higher than the top surface of the load-carrying platform 1. The above structural design enables the forklift forks 3 to be stably installed and operate, and facilitates the transfer of goods.
[0025] The end of the forklift forks 3 away from the mounting bracket 13 is set as an inclined surface, and resistance-reducing rollers 6 are equidistantly installed on the inclined surface at the end of the forklift forks 3. The above structural design enables the end of the forklift forks 3 to smoothly insert into the pallet, facilitating the smooth transfer of the pallet and goods.
[0026] The hydraulic rods 4 are symmetrically distributed about the center of the forklift forks 3. The length of the hydraulic rods 4 is greater than half of the length of the forklift forks 3. The center of the forklift forks 3 and the center of the limit posts 7 are in the same vertical plane. The limit posts 7 are slidably connected to the limit grooves 8. The front view and side view shapes of the limit posts 7 are both "丄" shaped. The above structural design enables the hydraulic rods 4 to control the forklift forks 3 to extend a sufficient distance. The limit posts 7 slide along the limit grooves 8, which not only improves the stability of the forklift forks 3 but also limits the forklift forks 3 to prevent the forklift forks 3 from tilting when transferring goods.
[0027] The locking nuts 11 are symmetrically distributed above and below the center of the side limit plates 12. The holes opened at the ends of the side limit plates 12 are slidably connected to the side threaded rods 10. The above structural design enables the locking nuts 11 to stably fix the positions of the side limit plates 12 on the side threaded rods 10, ensuring that the side limit plates 12 can limit and protect the goods from both sides.
[0028] The side limit plates 12 are symmetrically distributed about the center of the connecting plates 9. The distance between the symmetrically distributed connecting plates 9 is greater than the distance between the symmetrically distributed forklift forks 3. The above structural design ensures that the side limit plates 12 will not collide with the pallet, ensuring the normal operation of the forklift forks 3.
[0029] The vertical threaded rod 15 is threadedly connected to the top pressing plate 16. The vertical threaded rod 15 is symmetrically distributed about the center of the top pressing plate 16. The above structural design enables the vertical threaded rod 15 to stably drive the top pressing plate 16 to move when rotating, and can use thread self-locking to stably fix the top pressing plate 16 when stationary.
[0030] The side surface of the top pressing plate 16 is in contact with the inner vertical surface of the mounting bracket 13. The value of the height of the mounting bracket 13 is greater than the value of the length of the load-carrying platform 1. The above structural design enables the top pressing plate 16 to be adjusted and fixed within a large range along the inner side of the mounting bracket 13, and vertically squeeze and position goods of different sizes.

The pallet and goods are moved to the loading platform 1, the side limiting plate 12 on both sides can prevent the goods from falling, before the goods are transferred, the symmetrically distributed locking nuts 11 can be rotated away from the upper and lower end faces of the side limiting plate 12, the side limiting plate 12 is pushed to slide vertically along the side threaded rod 10 to the appropriate height, and then the symmetrically distributed locking nuts 11 are extruded to fix the upper and lower end faces of the side limiting plate 12, so that the lateral limiting effect of the side limiting plate 12 is ensured;
[0033] After the pallet and goods are moved to the loading platform 1, the control servo motor 14 drives the vertical threaded rod 15 to rotate, the vertical threaded rod 15 drives the top pressing plate 16 to vertically move down through the threaded connection, until the bottom surface of the top pressing plate 16 is in contact with the top of the goods, so that the goods are vertically extruded and positioned, the control servo motor 14 locks the vertical threaded rod 15, the vertical threaded rod 15 fixes the position of the top pressing plate 16 through the thread self-locking, and then the driving system of the heavy stacker can drive the loading platform 1 to transfer the whole goods, which is the working principle of the efficient goods carrying structure of the heavy stacker.
