地坑式升降平台

Pit type lifting platform

地坑液压升降平台广泛适用于汽车、集装箱、模具制造，木材加工，化工灌装等各类工业企业及生产流水线，满足不同作业高度的升降需求，同时可配装各类台面形式(如滚珠、滚筒、转盘、转向、倾翻、伸缩)，配合各种控制方式(分动、联动、防爆)，具有升降平稳准确、频繁启动、载重量大等特点，解决工业企业中各类升降作业难点，使生产作业轻松自如。

The pit hydraulic lifting platform is widely used in various industrial enterprises and production lines, such as automobile, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting requirements of different operation heights. At the same time, it can be equipped with various table forms (such as ball, roller, rotary table, turning, tipping, telescoping), and with various control methods (transfer, linkage, explosion-proof), it has the characteristics of stable and accurate lifting, frequent starting, large load capacity, etc, Solve all kinds of lifting operation difficulties in industrial enterprises, and make production operations easy and free.

地坑液压升降平台工作原理

Working principle of pit hydraulic lifting platform

液压油由叶片泵形成一定的压力，经滤油器、隔爆型电磁换向阀、节流阀、液控单向阀、平衡阀进入液缸下端，使液缸的活塞向上运动，提升重物，液缸上端回油经隔爆型电磁换向阀回到油箱，其额定压力通过溢流阀进行调整，通过压力表观察压力表读数值。

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.

升降平台液压缸的活塞向下运动(既重物下降)。液压油经防爆型电磁换向阀进入液缸上端，液缸下端回油经平衡阀、液控单向阀、节流阀、隔爆型电磁换向阀回到油箱。为使重物下降平稳，制动可靠，在回油路上设置平衡阀，平衡回路、保持压力，使下降速度不受重物而变化,由节流阀调节流量，控制升降速度。为使制动可靠，防止意外，增加液控单向阀，即液压锁，保证在液压管线意外爆裂时能自锁。安装了超载声控报警器,用以区别超载或设备故障。

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.
