With the development of industry, the application of stacker is more and more extensive. Here jujumi introduces the structural characteristics of stacker
The stacker is composed of metal structure, lifting mechanism, operating mechanism, fork telescopic mechanism, loading platform, cab, electrical control cabinet, etc
1. Metal structure: it is one of the main bearing parts of the stacker, which is composed of several parts, such as column, upper beam and lower beam.The upper part of the utility model is provided with a pulley or sprocket mechanism, an upper horizontal guide wheel, a cable dragging mechanism or a sliding contact line power supply device.The lifting mechanism is installed in the middle and lower part, and the lifting guide rail is installed in the inner side of the column to make the loading platform rise and fall smoothly.The outside of the column is equipped with maintenance ladder to facilitate maintenance, and the lower part is equipped with active and passive wheels.The whole structure has compact layout, high strength and good rigidity.
2. Wire rope lifting mechanism: it is used to drive the loading platform to rise and fall. The speed reducing motor controlled by frequency conversion speed regulation can realize stepless speed regulation for the ascending and descending speed, reduce the mechanical impact, and facilitate the accurate positioning of the loading platform.The wire rope type pulling mechanism greatly reduces the electric power of lifting and the volume of reducer, and reduces the operation cost. It adopts the direct connection reducer motor, and the lifting pulling pulley is installed on the extension shaft of reducer, with compact structure and reliable operation.
3. Running mechanism: the running mechanism drives the stacker to move horizontally along the running track, mainly including active wheel group, passive wheel group, horizontal wheel group, driving device and running buffer, etc.
4. Fork telescopic mechanism: it is the executive mechanism for the stacker to access goods. It is installed on the loading platform. The fork is composed of upper fork, middle fork and lower fork, which can extend to the left and right sides of the stacker.
5. Loading platform: it is a part of the stacker to receive goods and move up and down. It is a structural part firmly welded by vertical hanger and horizontal structure. It is equipped with shelf telescopic mechanism, rope loosening overload and rope breaking safety device, lifting sliding wheel, lifting guide wheel and side guide wheel.
6. Safety device: in order to ensure the safety of operators and drivers, the stacker is equipped with a series of mechanical and electrical safety devices.
7. Cab: the cab is mainly equipped with console and driver’s seat, with good lighting and visual field, which is convenient for the driver to operate.
