Description

Technical Field

[0001] The invention relates to the technical field of cargo lifting devices, and in particular to a lifting mechanism of a cargo stacker. Background Art

[0002] Stackers are mainly used for stacking, handling and accessing materials in warehouses and logistics sites to improve storage efficiency and accuracy. They can stack materials in a specified manner and height, and accurately stack them in designated locations by grabbing, lifting and moving materials, thereby achieving effective space utilization. They can transport materials between different warehouse areas, automatically travel along a predetermined path, and deliver goods from one location to another, greatly improving handling efficiency and accuracy.

[0003] At present, the lifting mechanism of the existing cargo stacker generally adopts three methods to lift materials: chain lifting, wire rope drum lifting and wire rope traction wheel lifting. The wire rope drum lifting is widely used in the device for the up and down movement of the cargo platform due to its simple structure. The existing wire rope drum lifting mechanism generally consists of a drum, a reduction motor, a wire rope and a pulley group. However, it is not convenient to add additional drums and wire ropes to share the load-bearing tension of the existing wire ropes. When the existing connected wire rope breaks, it is not possible to quickly add a new spare wire to urgently lift the cargo platform. For this reason, the lifting mechanism of the cargo stacker is needed to facilitate the addition of wire ropes to share the load-bearing tension of the wire ropes already connected to the cargo platform.

[0004] Based on this, the present invention designs a lifting mechanism of a cargo stacker to solve the above problems. Summary of the invention

[0016] 2. The present invention uses a limiting mechanism provided on the cargo platform. After placing the goods on the cargo platform, the linear motor is started, and the movement of the moving seat drives the resistance plate to rise, thereby extending the resistance area for the goods and adjusting it according to the placement height of the goods. After the resistance mechanism is adjusted, the telescopic rods fixedly installed at both ends of the rotating shaft are simultaneously contracted toward each other, so that the resistance mechanism moves closer to the goods until it contacts the goods, thereby clamping and limiting the goods and improving the stability of the cargo lifting process. When the goods are lifted to the placement height, the first output shaft of the driving motor drives the second gear to rotate, and the rotation of the second gear drives the first gear meshing with it to rotate, thereby driving the rotating shaft to rotate, so that the resistance mechanism flips downward 180°, which will not affect the stacking of goods on the cargo platform.
