Rigid chain lifting platform and electro-hydraulic lifting platform for automation

A: Rigid chain lifting platform The rigid chain lifting platform includes a fixed wishbone, a sliding wishbone, a pallet and a base, a rigid chain, a drive sprocket and a drive motor. One end of the chain is fixed on the pallet, and the drive motor is fixed on the pallet. On the base, its output shaft is connected to the drive sprocket, the rigid chain bypasses the drive sprocket, the pin shaft of the rigid chain meshing surface meshes with the teeth of the drive sprocket, and the rigid chain meshes with the drive sprocket and its extension direction occurs Change, in which the rigid chain between the drive sprocket and the pallet is in the upright state, so as to achieve the function of linear and vertical lifting in logistics; The rigid chain lifting platform is divided into single-chain type, double-chain type and four-chain type from the structure; The four-chain type is the four-corner position. The chain drive balance is the best. The maximum value can ignore the possibility of eccentric load. The single-chain and double-chain type are generally suitable for lifting small weight cargo. Advantages Because the rigid chain is hard-connected by the mechanical structure, it is in operation. The positioning is relatively accurate and high, the dynamic load and static load transfer equipment basically achieves zero buffering in the process, and the 24-hour static full load measurement basically achieves zero settlement; its application areas are mostly in some mold assembly industries that require positioning accuracy, butt joints. Common problems rigid chain The lithium pallet truck platform is driven by the steel chain driven by the motor. For example, in the case of supporting operation on the automatic assembly line body, the mechanical hard connection structure of the rigid chain will produce a certain degree of mechanical fatigue when running at high frequencies or at the calculation cycle. High temperature heating or motor overload may occur. In addition, the zero buffer of dynamic load and static load will also loss the main structure of the equipment under long-term operation, and subsequent maintenance costs are relatively high. B: Electric hydraulic lifting platform Electric hydraulic lifting platform It is mainly used for carrying materials to realize the lifting function through the electric hydraulic system. Most of them are used for warehouse cargo loading and unloading and for the material lifting and docking of the automatic production line operation system. The main structure is composed of a drive motor, a hydraulic pump, an oil cylinder, and a scissor support mechanism. The pump station feeds the oil cylinder to realize the vertical linear lifting of the material; the electric hydraulic lifting platform is divided into single shear or double shear according to the stroke; the pump station structure is originally divided into a built-in pump station and an external pump station, and the oil cylinder pump station is used as the power to pass the top The central axis of the lifting scissor mechanism achieves an even speed increase, which consumes less energy and has a large power output; in addition, with the long-term market application and practice, the overall technical performance of the electro-hydraulic lifting platform is relatively mature. Application advantages The electro-hydraulic lifting platform has a hydraulic assembly Provides lifting power, the entire lifting stroke is a piston reciprocating movement of the oil cylinder, and the joints of the equipment are equipped with joint bearings; it is more suitable for the high-frequency lifting requirements of the automated production line, and the overall energy consumption and the mechanical loss of the equipment itself are small. At present, mainstream products supporting automatic conveyor line lifting platforms in the market; low maintenance costs in the later period. Common problems. The equipment will have a slight settling pressure buffer during the transition between static and dynamic loads. The equipment is controlled by solenoid valve opening and closing to control positioning, and the accuracy is not mechanical. The positioning is high, but based on our existing technical strength and practical experience, there is basically no problem in the overall synchronization. In addition, it may be necessary to regularly check the operating conditions of the motor and the cylinder during high-load operation. The above application analysis , Is the practical experience summarized by our production technicians and project engineers in the process of customer application and actual operation, and we try to be objective and rigorous in the application of requirements! The ultimate goal is to reasonably solve the customer's on-site problems; I hope the above points can be helpful to your plan selection!
