Electric lifting column as some of the main places of maintenance equipment, more and more loved by everyone. What is the principle of anti-collision of electric lifting column? The following lifting column manufacturer Qi Xinlong will give you a good analysis.
The working principle of the electric lifting column is like a hydraulic or pneumatic piston, which is our non. Often familiar with the piston principle, for example, such as syringe, jack hydraulic cylinder. The hydraulic oil is formed by a vane pump. The fixed pressure enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve, and balance valve, so that the piston of the liquid cylinder moves upward. Lift heavy objects, return oil at the upper end of the liquid cylinder to the oil tank through the flameproof electromagnetic directional valve, its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.
The piston of the liquid cylinder moves downward (both the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic directional valve. In order to make the weight drop smoothly, brake safety. All right. Depend, a balance valve is set up on the oil return road to balance the circuit and maintain the pressure so that the falling speed is not changed by heavy objects. The throttle valve adjusts the flow and controls the lifting speed. Hydraulic is more complicated than electric, and its accessories are more. The hydraulic and electrical integration of the department adopts intra-cavity hydraulic technology. technology to achieve a one-piece seal. After the pressure oil enters the oil inlet cavity of the motor through the oil distribution shaft, it enters the top of the corresponding plunger cylinder through the housing groove of the barrier-free lifting platform. The hydraulic force FN acting on the plunger acts on the eccentric wheel center O through the connecting rod., Its tangential force F. A torque T is applied to the rotation center of the crankshaft to rotate the crankshaft counterclockwise. Due to the different positions of the three plunger cylinders, the magnitude of the torque generated is also different.
The electric lifting column is mainly driven up and down by the pneumatic and electromechanical integration inside the column. The main accessories are the electric gas spring and the power motor. The electric gas spring and the power motor are combined. After being energized, the pull rod can be controlled to drive the column. The advantage of this design is that the simple control method can be changed to realize the lifting, and the product cost will be reduced a lot. The electric lifting column is a complete miniature hydraulic drive system composed of a miniature motor and an integrated hydraulic cylinder. The system is built into the lifting column through structural parts. Each lifting column is an independent unit, which perfectly realizes The integration of microcomputer, electricity and liquid. Equipped with emergency release system, in case of power failure and other emergencies, the column can be lowered to open the passage.
