1. Crawler introduction
The water well drilling rigs track is composed of track shoes and track pins. The track pins connect the track shoes to form a tracking link. There are holes at both ends of the track shoe, which are engaged with the driving wheel, and there are induced teeth in the middle to regulate the track, and the water well drilling rig prevents the track from falling off during steering. Improve the rigidity of the track shoe and the adhesion of the track to the ground. The water well drilling rig site also has supporting chain wheels, supporting wheels, driving wheels, and rail links.
2. Cleaning of water well rig tracks
When cleaning the drilling rig, the sludge on the lower walking body should be cleaned at the same time. After the operation, whether the operator cleans the sludge on the lower walking body while cleaning the cab if there is sludge attached to the lower walking body. It is impossible to check the related parts. Therefore, please be sure to remove these sludges and inspect and maintain the lower walking body.

3. Crawler mounted drilling rigs track maintenance
During the construction process of the rotary drilling rig, the crawler tension should be adjusted according to the soil quality to cope with the differences in the soil quality of different construction sites. This can also extend the life of the machine. When the soil is soft, the track and the rail links are prone to adhere to the mud. Therefore, the track should be adjusted slightly loose to prevent the abnormal stress exerted on the rail links due to the adhesion of the mud. In construction sites all over the pebbles, the crawlers should also be adjusted slightly looser, so that when walking on the pebbles, the bending of the crawlers can be avoided. When the ground is firm and flat, it is best to adjust the track slightly. Adjustment of track tension: If the track is over-tightened, there will be a decrease in walking speed and walking power. This not only leads to a decrease in operating efficiency but also causes abnormal wear due to excessive frictional forces applied to the pins and bushings. On the contrary, if the track is adjusted too loosely, the track loosely rests on the drive wheel and carrier sprocket, 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. In this way, even if the reinforced lower walking body is not properly adjusted, it may cause unexpected failures.
Pay attention to reduce wear during the construction of the rotary drilling rig. Supporting sprockets, rollers, drive wheels, and rail links are all parts that are easy to wear, but there will be a large difference depending on whether the daily inspection is carried out or not. Therefore, as long as it takes a little time for proper maintenance, it is possible to control its wear level well. If you continue to use it in a state where some of the carrier rollers and rollers cannot run, it may cause the rollers to wear off and at the same time may also cause wear on the rail links. If you find a roller that cannot run, you must repair it immediately! In this way, you can avoid causing other failures. If you repeatedly walk on the inclined ground for a long time and turn suddenly, the side of the rail link will contact the side of the drive wheel and the guide wheel, thereby increasing the degree of wear. Therefore, you should avoid walking and leaning on slopes as much as possible. Straight-line travel and large turns can effectively prevent wear.
Bolts and nuts should be carefully checked: when the machine is working for a long time, the bolts and nuts will be loose due to the vibration of the machine. Especially the bolts and nuts on the lower walking body are easily affected. If you continue to run the machine with the track shoe bolts lose, there will be a gap between the bolts and the track shoe, which will cause cracks in the track shoe. Moreover, the occurrence of clearance may also increase the bolt holes between the track and the rail link, resulting in serious consequences that the track and rail link must be replaced without being able to be tightened. Therefore, the bolts and nuts should be regularly inspected and tightened to reduce unnecessary costs.
The following parts should be inspected and tightened: track shoe bolts; mounting bolts for supporting wheels and carrier chain wheels; mounting bolts for driving wheels; running piping bolts, etc. Also, check the parts that do not require maintenance.
In conclusion, DTH drilling rig supplier reminds the operator to pay more attention to the condition of the rotary drilling rig crawler, such as whether the bolts are loose? Are the supporting sprockets and rollers unable to rotate? Does the drive wheel leak oil? If you ignore the above abnormal conditions, you will eventually cause a serious accident. If the related parts are damaged due to the broken bolts and the support chain wheel or roller is deviated, the maintenance cost will be greatly increased.
