A floor rail type highly integrated intelligent iron driller

Abstract

The invention provides a floor rail type highly integrated intelligent iron roughneck, which integrates a lift car, a clamp head frame, a main back clamp and guide rails into a whole and consists of the lift car, the clamp head frame and the guide rails, wherein the lift car moves on the guide rails, the upper part of the clamp head frame is suspended and connected onto the lift car, in addition,the connection between the lift car and the lower part of the clamp head frame is realized through unscrewing, the lift car consists of a left side frame, a right side frame and a cross beam, the left side frame and the right side frame are respectively arranged on the two guide rails, the lift car drives a transmission gear to rotate through a lift car hydraulic motor for realizing the moving onthe guide rails. The floor rail type highly integrated intelligent iron roughneck can realize the application of a large-torque and wide-pipe-diameter-range rotary thread punching device and is applicable to the unscrewing on drill rods in any dimensions. The lift car, the clamp head frame, the main back clamp and the guide rails are integrated into a whole, so the weight of the whole equipment is greatly reduced, and the work efficiency is improved. The floor rail type highly integrated intelligent iron roughneck has the advantages that the automation degree is high, the full-process automatic operation of the work process can be realized, and the rotary thread punching operation of the whole site can be completed by one worker.

Description

(1) Technical field [0001] The invention relates to oil drilling engineering technology, in particular to a floor rail type highly integrated intelligent iron driller. (2) Background technology [0002] Iron driller is a multi-functional, safe and efficient drilling tool spinner, an important auxiliary equipment in automatic drilling, and has been widely used in foreign oil production. However, most of the iron drillers are arm-type structures. The iron drillers are installed on the lifting column through double-section or multi-section mechanical arms. The rotary punching device requires light weight and compact structure. Therefore this kind of structure can't realize the drilling pipe operation of big torque, big pipe diameter, and the working space is limited by the retractable range of mechanical arm. The spinner of the iron driller's pliers is generally connected with the punching device through a compression spring or a tension spring to realize a floating support co...

AI Technical Summary

Problems solved by technology

When the spinner is working, it needs to overcome the spring force, and the release of the stored energy of the spring after work will also cause impact on the equipment, and the spring is easy to fatigue and damage

Moreover, the integration of the entire iron driller is poor, the main and back pliers are separated, and the degree of automation is low. Generally, at least two workers are required for on-site operation.
