Iron roughneck floating type tong head hanging device and debugging method thereof

Abstract

The invention discloses an iron roughneck floating type tong head hanging device and a debugging method thereof. The device comprises a connecting frame fixedly connected with a tong head assembly, the telescopic end of an iron roughneck telescopic arm is connected with a lifting beam, a flexible hanging device and a buffer device are arranged between the connecting frame and the lifting beam, theupper end of the flexible hanging device is rotatably connected with the lifting beam, the lower end of the flexible hanging device is rotatably connected with the connecting frame, each buffer device comprises a guide pin, the guide pins are sleeved with multiple buffer springs, the connecting ends of the guide pins are in threaded connection with nuts, a transverse support perpendicularly penetrates into the buffer springs on the guide pins of the buffer devices in the radial direction, the two ends of the transverse support are fixedly connected with the connecting frame, a bottom cross beam of a hanging frame is parallel to the transverse support, the bottom cross beam of the hanging frame perpendicularly penetrates into the positions between the nuts on the guide pins of the buffer devices and the buffer springs in the radial direction, the upper end of the hanging frame is fixedly connected with the lifting beam, the structure is simple, maintaining is convenient, floatation connection is achieved, adaptation is good, impact can be effectively buffered, the service life is prolonged, and due to the adjustable structure, the action range is wide.

Description

technical field [0001] The invention belongs to the technical field of iron drillers, and relates to a floating clamp head suspension device for iron drillers, and also relates to a debugging method of the device. Background technique [0002] In automatic drilling production, the iron driller is currently the most advanced torque make-up and break-out equipment, which can complete the make-up and break-out of drill pipes, drill collars and other drilling tools, improve production efficiency and safety, and is a modern drilling tool. One of the important automation equipment in China. However, judging from the current feedback on the use of oilfield sites, the work efficiency of the existing iron drillers for make-up and breakout is low. Among them, a very important factor is that the iron drillers include spinners and punching pliers. The clamp head assembly cannot be well adapted to various working conditions of drilling tools at the drilling site, especially when the dri...
