The track tension of rotary drilling rig should be adjusted according to the soil quality in the construction process to cope with the difference of soil quality in different construction sites. This can also be done to extend the life of the machine. When the soil is soft, soil is easy to adhere to the track and rail link, so the track should be adjusted slightly loosely to prevent abnormal stress applied to the rail link due to the adhesion of soil. In the construction site with pebbles, the track should also be adjusted slightly loosely, so that the bending of the track plate can be avoided when walking on the pebbles. When the ground is firm and flat, it is best to adjust the track slightly tight. Adjustment of track tension: if the track is over-tensioned
The track tension of rotary drilling rig should be adjusted according to the soil quality in the construction process to cope with the difference of soil quality in different construction sites. This can also be done to extend the life of the machine. When the soil is soft, soil is easy to adhere to the track and rail link, so the track should be adjusted slightly loosely to prevent abnormal stress applied to the rail link due to the adhesion of soil. In the construction site with pebbles, the track should also be adjusted slightly loosely, so that the bending of the track plate can be avoided when walking on the pebbles. When the ground is firm and flat, it is best to adjust the track slightly tight. Adjustment of track tension: If the track is too tight, the walking speed and walking power will decrease. This not only results in a decrease in working efficiency, but also causes abnormal wear due to an excessive frictional force applied to the pin and the bushing. On the contrary, if the track is adjusted too loosely, the track loosely rides on the drive wheel and the support wheel, causing greater wear or damage. Moreover, when the loose crawler sags too much, it may come into contact with the frame and damage the frame. Thus, even if the reinforced lower traveling body is not properly adjusted, an unexpected failure may occur.
Rotary drilling rig construction should also pay attention to reduce wear. Sprocket, roller, drive wheel and rail chain links, these are easy to wear parts, but, according to the implementation of daily inspection or not, there will be a large degree of difference. Therefore, as long as it takes a little time for proper maintenance, it can be well controlled. If it continues to be used when part of the supporting chain wheel and the roller cannot operate, it may cause the roller to wear out, and it may also cause the wear of the rail chain link. If an inoperable roller is found, it must be repaired immediately! In this way, other failures can be avoided. If you repeatedly walk on the inclined ground for a long time and turn suddenly, the side of the rail chain link will contact the side of the driving wheel and the guide wheel, thereby increasing the degree of wear. Therefore, walking on inclines and sudden steering should be avoided as much as possible. Straight travel and large turns can effectively prevent wear.
Bolts and nuts should be carefully checked: when the machine works for a long time, the bolts and nuts will loosen due to the vibration of the machine. In particular, the bolts and nuts on the lower walking body are easily affected. If you continue to run the machine when the track shoe bolts are loose, there will be a gap between the bolts and the track shoe, which will lead to cracks in the track shoe. Moreover, the generation of the gap may also enlarge the bolt holes between the crawler and the rail link, resulting in the serious consequence that the crawler and the rail link must be replaced because of the inability to fasten. Therefore, bolts and nuts should be checked and tightened regularly to reduce unnecessary costs.
The following parts shall be inspected and fastened: track shoe bolts; mounting bolts of support wheel and support chain wheel; mounting bolts of driving wheel; bolts of traveling piping, etc. Parts that do not require maintenance should also be inspected.
