Under the action of the external magnetic field, the viscosity and yield stress of the magnetorheological fluid will change, and then the damping guide will be used to adjust the magnetic field strength.

At the same time, when the drilling rig as a whole produces a change, the contact guide end rod produces a change in the contact area of ​​the variable trigger area ring, which is then transmitted to the damping signal triggering sliding structure. With the cooperation of the damping signal triggering sliding structure, the metering electromagnetic gear and the active metering electromagnetic gear measure the displacement and angle change of the connecting rod. The damping signal triggers the sliding structure to absorb and transmit vibration energy through sliding and damping. When the vibration reaches a certain threshold, the damping signal triggering sliding structure will trigger a signal, so that the active metering electromagnetic gear, in cooperation with the second slot frame, is located on the surface of the slide slot frame for feedback adjustment sliding, thereby causing the active metering electromagnetic gear and the metering electromagnetic gear to come into contact, and according to the generated The feedback force is used to collect displacement and angle data through the metering electromagnetic gear, and transmitted to the high-speed data acquisition card for further processing and analysis.

The pressure and stress to which the drilling rig is subjected during operation are monitored in real time through the pressure response plate, and then the dynamic response of the drilling rig under different working conditions is fully monitored, providing high-precision data for analyzing the mechanical properties of the drilling rig. The magnetic variable rotating ball joint limits its range of motion through the magnetic limiting ring to ensure the stability and safety of the movement, and the setting of the balancing three-circle diameter parts ensures the stability of the structural mechanics dynamic quantity detection component in multiple directions. The magnetic variable rotating ball joint and the swivel joint can respond to the changes in the contact guide end rod in a timely manner, and determine whether the structural mechanics dynamic quantity detection component produces structural mechanical performance changes for translational safety during the operation of the drilling rig.

The four sets of vertical slide rails 1601 are composed of two sets of guide slide rails and two sets of dovetail slide rails. The two sets of electromagnetic guide rods 1604 are located inside the two sets of vertical slide rails 1601 and are tightly connected to the bottom of the electromagnetic coil connecting slide 1602.

The magnetorheological fluid guide network pipeline 1606 is composed of a spiral pipeline and a vertical pipeline. The connecting end of the spiral pipeline and the vertical pipeline is connected with a magnetorheological fluid detection variable box 1608. The bottoms of the two groups of electromagnetic guide rods 1604 are fastened with sealing rings 1605.
