How to safely tow away DTH hydraulic crawler rock drilling rig from the work site while the traveling motor is failed?

Abstract: The purpose of this paper is to discuss the fault phenomena and treatment methods of traveling motor in KHITAN-910 & KHITAN-910-PRO DTH hydraulic crawler rock drilling rig. By analyzing the technical principle of pulling out the sun wheel to pull the rig away from the work site, the practicability and reliability of this method are expounded. This study provides an effective solution for rig operators when facing such problems.

Introduction: With the continuous progress of science and technology, DTH hydraulic crawler rock drilling rig has become one of the indispensable equipment in modern engineering construction. However, due to its complex mechanical structure and precision electronic system, various failures will inevitably occur during the use of drilling rigs.
When the traveling motor of DTH hydraulic crawler rock drilling rig fails, the drilling rig should not be forced to continue moving forward. At this point, immediate measures should be taken to separate the sun wheel indicated by the red arrow from the drive shaft to ensure that the rig can be safely towed away from the work site by a trailer. This method is not only simple, but also has high security and reliability.
Conclusion: In this paper, the fault of the traveling motor of DTH hydraulic crawler rock drilling rig is deeply studied, and the corresponding troubleshooting method is proposed. Practice has proved that the method of unpulling the sun wheel can effectively solve the problem that the drilling rig can not drive away from the work site due to the fault of the traveling motor, and ensure the normal operation of the drilling rig. Therefore, we recommend that the majority of users in the face of similar problems, timely take the above measures to avoid unnecessary losses caused by failure.
