It belongs to the battery-powered stacking vehicle category. Pallet stackers are suitable for operations in narrow aisles and confined spaces, making them ideal tools for the warehousing and logistics industry. Many domestic and international manufacturers produce pallet stackers, and their functions are largely similar. However, due to specific operational characteristics in warehousing and logistics, subtle differences in the functions and structural design of pallet stackers can affect their operational efficiency and safety.

Two connecting rods 2 are rotatably connected to one side of the vehicle body 1. The vertical cross section of the connecting rods 2 is a hexagonal structure. Fork carriages 3 are slidably sleeved on the outer sides of the two connecting rods 2. A lifting mechanism 6 that drives the fork carriages 3 to rise and fall, and a rotating mechanism that drives the connecting rods 2 to rotate are provided on the vehicle body 1.

[0023] By rotating the two connecting rods 2 relative to each other, each connecting rod 2 drives its respective fork carriage 3 to rotate 180°, thereby completing the folding or overlapping of the fork carriage 3 and the vehicle body 1. This allows the fork carriage 3 to be stored and the length of the pallet stacker to be shortened.

[0024] like Figure 2 As shown, the rotating mechanism includes two meshing gears 5, with a first pulley fixedly connected to the top of each gear 5, and a second pulley fixedly connected to the bottom of each of the two connecting rods 2.

The sleeves 4 are rotatably connected between the bottom wall and the top wall inside the mounting groove 8. The top of the sleeves 4 has a through hexagonal cavity, and the sleeves 4 are slidably sleeved on the outside of the connecting rod 2 through the hexagonal cavity.

[0029] Through the sleeve 4, the fork carriage 3 can be raised and lowered by the lifting plate 602, and can also be rotated by the connecting rod 2.

[0030] like Figure 2 and Figure 3 As shown, a third pulley is rotatably connected to the vehicle body 1, a fourth pulley is fixedly connected to the bottom end of the threaded rod 601, a second transmission belt 9 is connected between the fourth pulley and the third pulley, and two servo motors 14 are installed on the vehicle body 1. The movable ends of the two servo motors 14 are fixedly connected to the upper parts of the third pulley and the first pulley, respectively.

[0031] Two servo motors 14 drive the third pulley and the first pulley to rotate forward or reverse, and to start or stop.

[0032] like Figure 1 As shown, both sides of the vehicle body 1 are provided with hidden slots 10, and the fork carriage 3 is adapted to the cavity of the hidden slot 10.

[0033] The hidden slot 10 is used to store the fork carriage 3. After the fork carriage 3 is rotated 180°, the fork carriage 3 will rotate into the cavity of the hidden slot 10.

[0034] like Figure 1 As shown, a front support frame 11 is fixedly installed on one side of the vehicle body 1. Multiple casters 12 are movably installed on both the front support frame 11 and the bottom of the vehicle body 1. A battery 13 is installed on the vehicle body 1.
