The control device 4 can record the torques of the balance weight compensation shaft 301 and the first compensation shaft 302 and the initial position of the measuring device 2. When the torque of the first compensation shaft 302 changes, the control device 4 automatically calculates the compensation torque of the balance weight compensation shaft 301, thereby controlling the servo module structure 303 to adjust the position of the balance weight compensation shaft 301, and further keeping the measuring device 2 at the initial position.

The connecting pieces are arranged on the placement grooves to fix the pipelines or edge structures of the measuring device 2, and the stability is better.

[0033] The number of servo module structures 303 is set to two groups. One group is used to control the balance weight compensation shaft 301, and the remaining group controls the first compensation shaft 302.

One side structure of the L-shaped clamping part is connected to the rod body part, and the two are fixed by welding or detachable connection. The other side structure can clamp the first compensation shaft 302. When the first compensation shaft 302 moves left and right, the system torque will change, thereby affecting the position of the measuring device 2. At this time, the servo module structure 303 corresponding to the balance weight compensation shaft 301 adjusts the position of the balance weight compensation shaft 301 to make it move in the reverse direction to a specific position, so as to balance the deformation caused by the change of torque, and further ensure that the measuring device 2 is kept at the installation position, with higher precision.

During installation, first calculate the torque of the balance counterweight compensation shaft 301 system and the torque of the first compensation shaft 302 system respectively, record the installation position of the measuring device 2 at the end of the rod body part, and pre-enter it into the PLC controller. When the torque of the first compensation shaft 302 system changes, the system will automatically calculate the compensation torque of the balance counterweight compensation shaft 301 system, thereby calculating the position that the balance counterweight compensation shaft 301 should reach, generating a reverse compensation torque, so as to maintain the installation position of the measuring device 2. By adding the balance counterweight compensation shaft 301, the adaptability to the change in the customer load is improved, the precision compensation control nodes are expanded, and the precision of the entire system is greatly improved.
