A fourth cylinder 22 is fixedly installed in the middle of the outer side of the side clamp 12, and the telescopic end of the fourth cylinder 22 is fixedly connected to the back side of the translation frame 21. A front baffle 23 is rotatably installed at the end of the translation frame 21 away from the fourth cylinder 22, and a third motor 24 for driving the front baffle 23 to rotate is installed on the translation frame 21.

[0040] Specifically, the third motor 24 is fixedly installed on the top inner side of the translation frame 21, and its drive shaft extends to the outside of the translation frame 21 with a third gear 25 fixedly installed at its end.

[0041] Two second rotating frames 28, perpendicular to the rear end of the main bearing plate 11, are symmetrically fixed at both ends.

The drive shaft of each second motor 29 passes through the second mounting plate 30 and has a second gear 31 that meshes with the corresponding end of the second semi-circular toothed ring 28-3.

[0044] The specific working principle of this invention is as follows:

[0045] In the initial state, the pallet-carrying platform and the cargo-carrying main plate of the pallet-carrying mechanism in this invention are both in the following position: Figures 1-2 The cargo clamping assembly is in a flat state, and the front baffle and side clamps are parallel to each other.

[0046] Using a forklift or other transfer equipment, a pallet containing goods is placed on the loading platform, while the goods on the pallet are positioned within the cargo-carrying mechanism. Then, two sets of first cylinders extend, causing two pallet clamps to jointly secure the pallet to be transferred. Two second cylinders simultaneously retract, causing two side clamps to move towards each other, thus clamping the sides of the goods. A third cylinder retracts, causing the top clamp to press against the top of the goods. Two fourth cylinders simultaneously extend, and two third motors drive two front baffles to flip relative to each other until they are parallel to the two side clamps. Then, two fourth cylinders simultaneously retract, causing the two front baffles to press against the front end of the goods. Through these actions, effective clamping and limiting of the goods in the front, back, left, right, and top directions are achieved.

[0047] After the goods are clamped and secured, the two first motors drive the two first rotating frames to rotate backward synchronously, and the two second motors drive the two second rotating frames to rotate backward synchronously. The pallet-carrying mechanism and the goods-carrying mechanism then rotate to... Figure 3 After reaching the indicated state, both the pallet to be replaced and the goods on it are in a slanted position. Then, the two first motors drive the two first rotating frames to rotate in opposite directions, resetting the support platform and the pallet to be replaced to their original positions. Figure 4 In the horizontal position shown, the two sets of first cylinders retract and reset. The worker removes the pallet to be replaced from the support platform and then places the new pallet on the support platform. Finally, the two second motors drive the two second rotating frames to rotate in opposite directions, placing the clamped goods onto the replaced pallet. After each second cylinder, the third cylinder, and each fourth cylinder extend and reset, the two third motors drive the corresponding front baffles to flip to a state parallel to the side clamps. Then, the replaced pallet with the goods is removed from the equipment by a forklift to complete the pallet conversion operation.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
