AI Technical Summary
In existing civil engineering equipment, the torque of the drive shaft causes rotation through bearing friction, which leads to wire entanglement problems, and the rotation of the excavation device and the housing as a whole reduces the efficiency of the operation.
The system employs a locking linkage device, which maintains the drive unit in a stationary state through a relative rotation sensor and control device between the drive shaft and the locking linkage device. The stationary state of the drive shaft is maintained by a pinion and internal gear structure, and the working depth is monitored by a depth sensor.
It effectively prevents the drive shaft from rotating, avoids wire entanglement, improves work efficiency, and maintains stable operation of the device in muddy and watery environments.
