Many users and rig manufacturers in order to move, walking convenience, the tunnel rig refitted on the track. In order to adjust the Angle, the cylinder hydraulic lift. Shallow holes do not need to consider stability, even if the stability is poor, it can also meet the drilling engineering design hole depth requirements, but the hole depth, the stability of the rig installation is more important, with the continuous increase of drilling depth, the rig in the process of rotary drilling, is bound to produce more and more centrifugal force, resulting in serious shaking of the rig.

It is a matter of principle to consider a variety of factors when modifying the track type of tunnel prospecting rig, and to add a walking function at the same time, do not weaken its main function. In the no-load time, a variety of fancy functions and actions are often the highlight of attracting the public, we do not consider is the practicality of various drilling conditions in the future, safety, long-distance transportation and other factors.

In order to reduce the complexity of hydraulic system maintenance and the incidence of hydraulic failure, it is recommended to add independent hydraulic control system in the reconstruction and upgrading of full hydraulic tunnel prospecting rig, especially the increase of hydraulic function.

When the fuselage is horizontal to vertical, it is supported by a single or double oil cylinder, so that the rig rotates around the installation beam of the front pipe clamp, and when the rig turns to the right Angle, the stability of the entire equipment is actually handed over to the two pipe clamp of the front beam and the oil cylinder of the support rig. Because the mass of the rig is relatively large, the inertia generated when it is subjected to centrifugal force is greater. The overall shaking of the machine is inevitable, which will affect the drilling situation, slope, depth, etc., so in the application and modification of the caterpillar part, we should fully consider the main factors of drilling, do not blindly follow, and eventually use higher equipment costs and buy lower products.
