Abstract

The invention discloses an iron driller's floating clamp head suspension device and a debugging method thereof. A flexible suspension device and a buffer device are arranged between them; the upper end of the flexible suspension device is rotatably connected with the suspension beam, and the lower end of the flexible suspension device is rotatably connected with the connecting frame; each buffer device includes a guide pin, and a number of buffer springs are set on the guide pin. The connecting end of the cross brace is threaded to connect the nut; the cross brace is radially and vertically passed through the middle of several buffer springs on the guide pins of several buffer devices, and the two ends of the cross brace are fixedly connected to the connecting frame; the bottom beam of the hanger is parallel to the cross brace, and the bottom of the hanger The crossbeam is radially and vertically passed between the nuts on the guide pins of several buffer devices and the buffer springs, and the upper end of the hanger is fixedly connected to the hanging beam, which has a simple structure and is convenient for maintenance. The floating connection has good adaptability, effectively cushions the impact and prolongs the service life. Long life, adjustable structure, wide range of action.

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...
