Reasons why the crawler-type down-the-hole drilling rig broke off the chain
Why does the crawler type down-the-hole drilling rig go off the chain? What are the causes? Let’s take a look at it with the manufacturer of crawler down-the-hole drilling rigs.
1. Common faults of the tensioning hydraulic cylinder cause the chain to detach. At this time, it is necessary to check whether the tensioning hydraulic cylinder has forgotten to add grease, and whether there is oil leakage in the tensioning hydraulic cylinder.
2. The track of the down-the-hole drilling rig is seriously damaged, causing the chain to detach. Once used for a long time, the track will definitely be damaged, and damage to the chain ribs, chain tubes and other components on the track will also cause the track to dechain.
3. Chain detachment caused by damage to the chain guard. At present, basically all down-the-hole drilling rigs have chain guards on their tracks, and the chain guard can play a very important role in preventing chain detachment, so it is also important to check whether the chain guard is damaged.
4. The drive electric motor ring gear of the down-the-hole drilling rig is damaged, causing the chain to detach. As for the drive motor ring gear, once it is seriously damaged, we must replace it, otherwise dechaining is inevitable.
5. Chain detachment caused by damage to the supporting sprocket. Under normal circumstances, oil seal leakage of the supporting sprocket will cause serious damage to the supporting sprocket, which will cause the track to dechain.
6. Dechaining caused by damage to the guide wheel. When checking the guide wheel of the down-the-hole drilling rig, check whether the screws on the guide wheel are missing or broken. Is there any deformation in the slot of the card guide wheel?
The above is a summary for you of the reasons why the crawler type down-the-hole drilling rig is dechained. I hope it will be helpful to you. If you have any questions, please feel free to contact us at +8613626357322.
