Embodiment 1

[0036] figure 1 The structure of the drill rod of the present invention is shown. A self-rotating and quick-detachable auger rod, comprising an intermediate rod 1, a male joint 2, and a female joint 3, the outer side of the intermediate rod 1 is provided with a helical blade 4, one end of the intermediate rod 1 is welded to the female joint 3, and the other end is welded to the female joint 3. The male joint 2 is welded; the male joint 2 and the female joint 3 are connected to the middle rod 1 through a friction welding process, and the spiral blade 4 is welded on the surface of the middle rod 1 with a pre-tightening force.

[0037] Figure 2~5 The structure of the male connector is shown. The male joint 2 is a cylinder with a blind hole 2.1 inside, the axis of the blind hole coincides with the overall central axis of the male joint, and the hole is a circular hole; the male joint is divided into three sections, the first section is a hexagonal prism structure, and the inte...

Abstract

The invention discloses an automatic-rotating rapid dismounting and mounting type spiral drill rod. The automatic-rotating rapid dismounting and mounting type spiral drill rod comprises a middle rod, a male joint and a female joint; a spiral blade is arranged on the outer side of the middle rod, one end of the middle rod is welded with the female joint, and the other end of the middle rod is welded with the male joint; the male joint is divided into three segments, and a pushing rod is arranged in the male joint; a through hole in the pushing rod is communicated with L-shaped holes in the third segment of the male joint, and a stirring rod penetrates the through hole; and a check block is arranged in a square hole in the second segment of the male joint, and after the female joint is matched with the male joint, the pushing rod pulls a spring to enable the check block to rotate so as to achieve dismounting and mounting of the drill rod. According to the joints, the spiral drill rod of gas drilling equipment can be automatically mounted and dismounted, labor intensity of workers can be relieved, personal safety of the workers is ensured, and the use performance and the working efficiency of the drill rod are improved.

Description

technical field [0001] The invention relates to an automatically rotating and quickly dismounting helical drill rod, which belongs to the technical field of drilling. Background technique [0002] In the prior art, there are mainly two types of drill pipes used in coal mine tunnel drilling rigs, namely joint threaded drill pipes and pin-connected drill pipes. The first type, the joint threaded drill pipe is threaded connection between the drill pipe and the drill pipe. When workers install the drill pipes underground, they need to lift and fix the two front sections of the drill pipes, start the drilling rig to drive the rear end drill pipes to rotate, and the threads rotate with each other and mesh together. This installation process takes a long time, the installation efficiency is low, and the threads often It will be distorted and deformed due to improper operation and excessive force. When the drill pipe is working, it cannot be rotated in reverse, otherwise the brigh...
