AI Technical Summary

Technical Problem

Existing vehicle-mounted oil drilling rigs are prone to detachment of the excavator head from the connecting cylinder due to loose connections during long-term, high-load operation, which affects the drilling process and the equipment is also prone to damage due to overheating.

Method used

The connection structure, which tightly integrates the second spiral thread with the first spiral thread, is combined with locking components and round fasteners to ensure a stable connection. The equipment temperature is reduced through a heat-conducting layer and a coolant circulation system.

Benefits of technology

It improves the stability of the equipment during high-frequency operation, reduces failures caused by loosening and overheating, lowers maintenance costs and downtime, and extends the service life of the equipment.
