Geotechnical centrifuge plug plate hoisting hole opening and closing device and using method
The invention discloses a geotechnical centrifuge plug plate hoisting hole opening and closing device and a using method. The opening and closing device is integrally embedded in a plug plate and comprises a door body unit, a driving unit and a locking unit, a servo motor and a worm and gear reducer in the driving unit serve as power sources of the device, the door body unit is connected through a chain wheel, a chain and a double-rocker mechanism, the dead point position characteristic of the mechanism is advantageously applied, and locking is achieved. The dual functions of automatic opening, closing and pressing of the door body unit can be achieved; the two ends of the door body unit adopt a translation wedge type locking scheme, after the door bolt translates, the wedge-shaped surface of the dragging head is pressed in place, the door bolt dragging head is limited by the electromagnetic lock, the door body is locked by the door bolt through the pressing cushion block, and multi-point effective locking of the long-span door body is ensured. The device has the advantages of being stable in driving, reliable in locking and capable of saving space, an experimental model and an airborne device can enter and exit conveniently when the door body is opened, periodic aerodynamic loads generated by rotation of the geotechnical centrifuge can be effectively resisted when the door body is closed, and mechanical vibration and airflow squeal are avoided.
本发明公开了一种土工离心机塞板吊装孔启闭装置及使用方法。该启闭装置整体内嵌于塞板内，包括门体单元、驱动单元和锁紧单元，驱动单元中的伺服电机和蜗轮蜗杆减速器作为装置动力源，通过链轮、链条和双摇杆机构连接门体单元，有利应用机构“死点位置”特性，可以实现门体单元自动启闭和压紧双重功能；门体单元两端采用平移斜楔式锁紧方案，门栓平移后拖头楔形面入位压紧，电磁锁对门栓拖头进行限位，门栓通过压紧垫块锁紧门体，保证长跨度门体的多点有效锁紧。本发明装置具有驱动稳定、锁紧可靠和节省空间的特点，门体开启时方便实验模型和机载装置进出，门体关闭时能够有效抵抗土工离心机旋转产生的周期性气动载荷，避免机械振动和气流啸叫。
