| description | The utility model relates to a protection device for petroleum drill rod power tongs, in particular to a pneumatic control protection device for drill rod power tongs. The technical scheme is that a pneumatic control system is added in front of a two-position three-way air valve of the drill rod power tongs, the pneumatic control system is composed of a mechanical valve, a pneumatic control valve and a main air pipeline. An air source is communicated through the main air pipeline, an air control valve is arranged on the main air pipeline, and the other end of the air control valve is communicated with the mechanical valve. The pneumatic control protection device for drill rod power tongs has the advantages that by improving an air path system, the problem that the drill rod power tongs are easy to cause injuries in the process of misoperation is avoided, and potential hazards of production accident are reduced. |
