Abstract

The invention provides a protective device for a top drive back-up wrench. The protective device comprises two semi-tube protective tiles fastened together, a torsion spring for controlling the closure of the two protective tiles, a pull mechanism for controlling the opening of the two protective tiles, and a hollow handle below the protective tiles; the bottom ends of the protective tiles are hinged to a pin which is mounted at the top of the handle through a support; the pull mechanism comprises a control shaft mounted in the hollow of the handle, switch control holes each arranged in the corresponding protective tile, a control line connected between the switch control holes and the control shaft, and a roller arranged at the top end of the handle for supporting the control line; the lower end of the control shaft is provided with a control grip, and the bottom of the handle is provided with a locking portion for fixing the control grip. The control shaft is pushed to the front end of the handle through the control grip so as to loosen the control line, the protective tiles are closed by the torsion spring, slurry spouting at the top drive back-up wrench can be effectively prevented, a drill floor top can be kept clean and safe, and workload of drilling workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of supporting tools for petroleum engineering drilling, and in particular relates to a protection device for top drive back tongs. Background technique [0002] The full name of top drive is TDS (TOPDRIVE DRILLING SYSTEM), which is a new drilling technology emerging in the international drilling field in the 1980s and a major breakthrough in rotary drilling technology. The advantages of time, connection of a single pipe for circulation at any time in case of emergencies, reduction of stuck pipe accidents, and significant improvement of drilling operation capacity and efficiency have been continuously promoted and applied. However, during drilling operations, when connecting a single root or column, when the top drive back tong and the drill pipe are undocked, mud often flows out or sprays out, polluting the drilling floor surface and equipment on the drilling floor, and increasing the work of drilling worker...
