Truck-mounted drilling rig rod changing device

Abstract

The invention discloses a truck-mounted drilling rig rod changing device. The truck-mounted drilling rig rod changing device comprises a machine body 1, a translation supporting leg 2, stabilization supporting legs 3, a drill rod feed machine body 4, a mounting base 5, a clamping mechanism 6, a machine body angle modulation oil cylinder 7, a lifting device 8 and an adjusting oil cylinder 9, wherein the translation supporting leg 2 and the two pairs of stabilization supporting legs 3 are mounted on the machine body 1; the drill rod feed machine body 4 is hinged to the mounting base 5 through a rear axle; the clamping mechanism 6 is mounted on the drill rod feed machine body 4; the lifting device 8 is mounted on one side of the machine body 1; the two ends of the adjusting oil cylinder 9 are fixed to the machine body 1 and the lifting device 8 respectively; the machine body angle modulation oil cylinder 7 is hinged to the drill rod feed machine body 4 and the machine body 1, and the pitchup angle of the drill rod feed machine body 4 can be controlled; a drill rod 11 is in butt joint with a drilling rig power head 10 through the rod changing device. The truck-mounted drilling rig rod changing device is simple in structure and convenient to operate, the working face is low, a rod adding device is small in size and light in weight, labor intensity of field workers is low, the automation degree is high, and working efficiency is improved.

Description

Convenient transportation and other advantages. Vehicle-mounted drilling rigs are widely used in the drilling construction of large-diameter water wells, coalbed methane extraction wells, oil and gas wells, etc. It is a mainstream development trend of drilling rigs in the future, and the supporting equipment ...

AI Technical Summary

Problems solved by technology

For large ground vehicle-mounted drilling rigs, the operation of loading and unloading drill pipes must also consider the needs of drilling tools such as drill pipes and casings. Because the drill pipes are long and heavy, it is difficult to carry and change pipes, and the labor intensity of workers is high. Large, inefficient, and likely to cause safety hazards
