The lowering platform mainly realizes the lifting function through the pressure transmission of hydraulic oil. Its shear fork mechanical structure makes the lifting have high stability, wide operation platform and high bearing capacity, which makes the range of high-altitude operation larger and suitable for multiple people to work at the same time. It makes the higher the efficiency of high-altitude operation and has safety guarantee.
Working principle: the hydraulic oil forms the corresponding pressure by the vane pump and enters the lower end of the hydraulic cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve and balance valve to make the piston of the hydraulic cylinder move upward and raise the weight. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the flameproof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve, Observe the reading value of the pressure gauge through the pressure gauge.
The piston of the hydraulic cylinder moves downward (i.e. the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil at the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control check valve, throttle valve and explosion-proof electromagnetic directional valve. In order to make the weight drop steadily and brake safely, the lifting platform is equipped with a balance valve on the oil return road to balance the circuit and maintain the pressure, so that the lowering speed will not be changed by the weight. The flow is adjusted by the throttle valve to control the lifting speed. In order to ensure safe and reliable braking and avoid accidents, a hydraulic control check valve, namely hydraulic lock, is added to ensure safe self-locking in case of accidental bursting of hydraulic pipeline. Overload sound control alarm is installed to distinguish overload or equipment failure.
The hydraulic lifting platform is applicable to various industrial enterprises and production lines such as automobiles, containers, mold manufacturing and chemical filling. It can meet the lifting requirements of different operation heights. At the same time, it can be equipped with various table forms and cooperate with various control modes. It has the characteristics of stable and accurate lifting, frequent startup and large load capacity, so as to solve various lifting operation difficulties in industrial enterprises.
