Intelligent variable-resistance real-time monitoring and early warning anchor rod
The invention relates to an intelligent variable-resistance real-time monitoring and early-warning anchor rod, which belongs to the field of tunnel supporting and comprises a barrel, a piston and a piston rod are arranged in the barrel, a liquid storage chamber is arranged in the wall of the barrel and is communicated with the inside of the barrel through an oil channel at the end of the piston rod, and an aperture communicated with cavities on two sides of the piston is formed in the piston. An electromagnetic valve and a flow sensor are arranged in the aperture, and an oil pressure sensor is further arranged on one side of the piston; cavities on the two sides of the piston are filled with hydraulic oil, and the liquid storage chamber is filled with high-pressure nitrogen. Comprising an upper computer, and the upper computer is connected with an electromagnetic valve, a flow sensor and an oil pressure sensor and used for receiving data of the flow sensor and the oil pressure sensor and controlling opening and closing of the electromagnetic valve. The upper computer analyzes the stress state of the anchor rod through monitoring data of the oil pressure sensor and judges whether the electromagnetic valve needs to be opened for yielding or not. The upper computer calculates the yielding distance through data monitored by the flow sensor.
本发明涉及一种智能化可变阻力实时监测预警锚杆，属于隧道支护领域，包括筒体，所述筒体内设有活塞及活塞杆，所述筒体的壁内设有储液室，其通过活塞杆端的油液通道与筒体内连通，所述活塞内设有连通活塞两侧空腔的孔径，所述孔径内设有电磁阀和流量传感器，所述活塞一侧还设有油压传感器；所述活塞两侧的空腔内都装满液压油，所述储液室内装有高压氮气；包括上位机，所述上位机与电磁阀、流量传感器、油压传感器连接，用于接收流量传感器、油压传感器的数据，并控制所述电磁阀的开闭；所述上位机通过油压传感器监测数据对锚杆受力状态进行分析，判断是否需要开启电磁阀来进行让压；所述上位机通过流量传感器监测数据来计算让压距离。
