A mutually exclusive operating system that can control the action of power tongs

Abstract

The present invention provides a mutually-exclusive operating system capable of controlling the action of power tongs. The mutually-exclusive operating system includes power tongs, a control device and a linear driving mechanism; the linear driving mechanism is controlled by the control device so as to drive the power tongs to move linearly; the control device comprises a relay group; the relays of the relay group are sequentially connected with one another; each relay includes a common end, a normally closed end and a normally open end; under an initial state, the common end is conductively connected with the normally closed end; under the access of external control signals, the common end veers to be conductively connected with the normally open end; the common end of the relay which is arranged at the first place in the relay group is connected with a power source; an operator can control the power tongs through the remote control device so as to intuitively observe the position of the power tongs to adjust the power tongs; the operator can remotely control the operation of the power tongs, and therefore, safety accidents can be decreased; and the relay group is correspondingly arranged and connected in the operation system, so that mutually-exclusive operation can be realized, and misoperation can be avoided.

Description

technical field [0001] The invention relates to the field of oil drilling equipment, in particular to a mutually exclusive operating system capable of controlling the action of a power tong. Background technique [0002] As the international oil price continues to drop, major oil companies at home and abroad have adopted measures to reduce costs and improve efficiency in response to the production time domain. Many companies have begun to use orbital drill pipe power tongs, which have the advantages of easy handling and installation, strong environmental adaptability and easy operation, which can greatly improve mining efficiency. At present, this kind of drill pipe power tong basically requires manual operation of the reversing valve. However, the actions of operating the power tong to advance, retreat, rise, and descend must be mutually exclusive, so operators need to be trained on the operation process. When operating manually, it is necessary to stand beside the drill p...

AI Technical Summary

Problems solved by technology

When operating manually, it is necessary to stand beside the drill pipe tongs. When operating the reversing valve, it is impossible to operate while observing the position of the drill pipe tongs. There are certain safety hazards in manual operation, and even if the process training There can still be misuse
