The adjustment is flexible and convenient, so that the drilling depth of the drilling rig is not limited to the initial height of the drilling component, further improving the applicability of the device, and can be used in different use environments. The present invention has a simple structure and is easy to use; it increases the stability of piling, improves the breakthrough ability of piling, and then improves the efficiency and quality of piling, and the bearing capacity of the pile column is higher; and piling does not generate noise, and will not disturb people during construction, which greatly improves the applicability of the device and is convenient for promotion and application.

[0040] Furthermore, a supporting hydraulic rod 38 is provided at the rear end of the traveling vehicle 1 of the present embodiment.
