However, in the actual use process, due to the influence of external environment (such as wind, ground vibration, etc.), and the instability of the equipment itself, the accuracy of measurement is often affected.

[0003] As shown in Figure 1 The prior art ranging technology is provided with walking wheels 2 at the bottom of the ranging device 1, and the opposite two side faces extend downward to form limiting baffle plates 3.

[0004] Early ranging devices mostly rely on manual adjustment by the operator to ensure the accuracy of measurement. This way is not only inefficient, but also difficult to realize stable measurement for a long time. With the development of technology, some automatic stabilizing devices begin to be introduced, such as absorbing vibration through spring, hydraulic system and other physical means, or using electronic control system to adjust the height of the probe in real time, and absorbing external impact and vibration through the elastic deformation of the spring. It is the most common shock absorbing way. The damping effect is limited, and it is easy to fail under high frequency vibration. By using the shape memory effect of memory alloy, it can restore to the preset shape at a certain temperature, so as to realize the damping and stabilizing effect. This kind of material performs well in some special applications, but the cost is high, and it is sensitive to temperature. By using the incompressibility of liquid to absorb and buffer vibration energy. Compared with spring shock absorber, hydraulic shock absorber has better damping effect and longer service life. The cost is relatively high, and it needs regular maintenance.

[0005] These methods improve the stability and accuracy of ranging to some extent. However, the existing solutions still have some limitations, such as high cost, complex maintenance, insufficient adaptability and other problems. UTILITY MODEL CONTENTS
