Currently, the stacking machines on the market are mainly divided into single column stacking machines and double column stacking machines. The main function of the stacker is to run back and forth in the passageway of the three-dimensional warehouse, storing the goods located at the lane entrance into the cargo compartment of the shelf, or taking out the goods from the cargo compartment and transporting them to the lane entrance. Here is an introduction to the structural composition of the lower stacker: The stacker is mainly composed of several parts, such as the lower crossbeam, the loading platform, the fork mechanism, the upright post, the upper crossbeam, the horizontal running mechanism, the lifting mechanism, the electric control cabinet, the safety protection device, and the electrical control system.
1. Main structure
The main structure of the stacker mainly consists of an upper beam, a column, a lower beam, and a control cabinet support. The upper and lower crossbeams are welded into a box shaped structure by steel plates and section steels, with good cross-sectional performance. The running wheel axle holes on both sides of the lower crossbeams are clamped and processed in one step by a floor type boring and milling machine, ensuring the parallelism of the axes of the driving and driven wheels, thereby improving the stability of the entire machine's operation; The column is made of square steel pipes. Two flat steel rails are welded on both sides of the square steel pipes at one time. The surface of the rails is hardened and has good wear resistance. Automatic welding technology with special devices is used in welding, effectively overcoming the deformation of the overall structure; The upper beam is welded onto the column, and the column and lower beam are positioned through flanges and connected with high-strength bolts. The entire main structure is characterized by light weight, torsion resistance, bending resistance, high stiffness, and high strength.
2. Loading dock
The cargo platform is a component that moves vertically up and down through the power traction of the lifting mechanism. It is an L-shaped structure welded by a vertical frame and a horizontal frame. The vertical frame is used to install the lifting guide wheel and some safety protection devices. The horizontal frame is made of seamless steel pipes, fully meeting the requirements for carrying cargo.
3. Horizontal running mechanism
The horizontal running mechanism is composed of a power drive and a set of active and passive wheels, which is used for running the entire equipment roadway direction.
4. Lifting mechanism
The lifting mechanism is composed of a drive motor, a drum, a sliding group, and a steel wire rope, used to lift the cargo platform for vertical movement.
5. Fork mechanism
The cargo fork telescoping mechanism is a mechanism composed of a power driven upper, middle, and lower fork, which is used for the movement of cargo perpendicular to the direction of the roadway. The lower fork is fixed on the loading platform, and the three forks are linearly retracted through chain transmission.
6. Guide wheel device
The stacker adopts three sets of guide wheel devices: upper and lower horizontal guide wheels and lifting guide wheels. The upper and lower horizontal guide wheels are installed on the upper and lower crossbeams respectively, which are used to guide the stacker to move horizontally along the roadway direction. The lifting guide wheel is installed on the platform and moves up and down along the column guide rail to guide the vertical movement of the platform. At the same time, the load is supported by the guide wheel and transferred to the main structure.
