一种悬浮气动起吊装置及悬浮气动起吊方法
摘要：
本发明公开了一种悬浮气动起吊装置及悬浮气动起吊方法，其中，一种悬浮气动起吊装置，包括气源、电源接入电路、换向阀、电气比例阀、两位三通电磁阀、气动起吊装置、控制器以及拉力传感器，换向阀和电气比例阀分别与气源和两位三通电磁阀连接，两位三通电磁阀与气动起吊装置连接，电源接入电路具有用于控制向电气比例阀、两位三通电磁阀以及控制器供电的控制开关；控制器将检测数据值与设定值进行对比，若小于设定值时，控制电气比例阀将进气口与两位三通电磁阀连通，若大于设定值时，控制电气比例阀将排气口与两位三通电磁阀连通。本发明的悬浮气动起吊装置和悬浮气动起吊方法可以对任意重量的吊装物实现快速上升和下降。
摘要（英）：

The invention discloses a suspension pneumatic lifting device and a suspension pneumatic lifting method. Specifically, the suspension pneumatic lifting device comprises a gas source, a power access circuit, a reversing valve, an electropneumatic proportional valve, a two-position three-way electromagnetic valve, a pneumatic lifting apparatus, a controller and a tension sensor. The reversing valve and the electropneumatic proportional valve are respectively connected to the gas source and the two-position three-way electromagnetic valve, the two-position three-way electromagnetic valve is in connection with the pneumatic lifting apparatus, and the power access circuit has a control switch for controlling power supply to the electropneumatic proportional valve, the two-position three-way electromagnetic valve and the controller. The controller compares the test data value with a set value, if the test data value is smaller than the set value, the electropneumatic proportional valve is controlled for communicating an air inlet with the two-position three-way electromagnetic valve, if the test data value is greater than the set value, the electropneumatic proportional valve is controlled for communicating an air outlet with the two-position three-way electromagnetic valve. The suspension pneumatic lifting device and the suspension pneumatic lifting method provided by the invention can realize rapid raising and descending of a hoisted object with any weight.
