Abstract

The invention discloses a drill rod guiding frame which comprises drill rods, an upper drill rod guiding frame and a lower drill rod guiding frame. Drill rod holders are arranged on the drill rods, an upper drill rod guiding frame oil cylinder is arranged on the upper drill rod guiding frame, and a lower drill rod guiding frame oil cylinder is arranged on the lower drill rod guiding frame. According to the drill rod guiding frame, the multiple drill rods can be connected together, and fixing of the drill rods is facilitated so that the drill rods cannot make direct contact with fixing pieces, and the service life is prolonged; in the working process, the drill rods can be firmly fixed, and swing of the drill rods is reduced; and through arranged abrasion-resisting cow tendons, direct contact of the guiding frames and the drill rods can be avoided so that the drill rods cannot be damaged, the friction coefficient is increased, the drill rods can be better fixed, the drill rods are not prone to being clamped, and the stability of a drilling machine and the and accuracy of drilling are improved.

Description

technical field [0001] The invention relates to a guide frame, in particular to a drill pipe guide frame, which belongs to the field of construction machinery. Background technique [0002] Drilling rigs are mainly used for open-pit geological exploration drilling and engineering drilling that requires explosives to be buried during various mountain opening operations. The drill pipe is a steel pipe with a threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit to raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times. Most of the drilling rigs...
