地坑液壓升降平臺(tái)工作原理

Working principle of pit hydraulic lifting platform

液壓油由葉片泵形成一定的壓力，經(jīng)濾油器、隔爆型電磁換向閥、節(jié)流閥、液控單向閥、平衡閥進(jìn)入液缸下端，使液缸的活塞向上運(yùn)動(dòng)，提升重物，液缸上端回油經(jīng)隔爆型電磁換向閥回到油箱，其額定壓力通過溢流閥進(jìn)行調(diào)整，通過壓力表觀察壓力表讀數(shù)值。

The hydraulic oil forms a certain pressure by the vane pump, enters the lower end of the hydraulic cylinder through the oil filter, the explosion-proof electromagnetic reversing valve, the throttle valve, the hydraulic control check valve, and the balance valve to make the piston of the hydraulic cylinder move upward and lift the heavy object. The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve. The reading value of the pressure gauge is observed through the pressure gauge.

升降平臺(tái)液壓缸的活塞向下運(yùn)動(dòng)(既重物下降)。液壓油經(jīng)防爆型電磁換向閥進(jìn)入液缸上端，液缸下端回油經(jīng)平衡閥、液控單向閥、節(jié)流閥、隔爆型電磁換向閥回到油箱。為使重物下降平穩(wěn)，制動(dòng)可靠，在回油路上設(shè)置平衡閥，平衡回路、保持壓力，使下降速度不受重物而變化,由節(jié)流閥調(diào)節(jié)流量，控制升降速度。為使制動(dòng)可靠，防止意外，增加液控單向閥，即液壓鎖，保證在液壓管線意外爆裂時(shí)能自鎖。安裝了超載聲控報(bào)警器,用以區(qū)別超載或設(shè)備故障。

The piston of the hydraulic cylinder of the lifting platform moves downward (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 from 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 and reliably, a balance valve is set on the oil return path to balance the circuit and maintain the pressure, so that the drop speed will not be changed by the weight. The throttle valve regulates the flow and controls the lifting speed. In order to ensure safe and reliable braking and prevent accidents, hydraulic control check valve, namely hydraulic lock, is added to ensure safe self-locking in case of accidental burst of hydraulic pipeline. An overload sound control alarm is installed to distinguish overload or equipment failure.
