Technical Field

The utility model relates to the technical field of drilling rigs, and in particular to a hole deflection prevention device for drilling rigs.

Background Art

A drilling rig is a complex machine, which consists of machines, units and mechanisms. A drilling rig is a mechanical equipment that drives the drill tool to drill underground to obtain physical geological data during the exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.). It is also called a drilling machine. Its main function is to drive the drill tool to break the rock at the bottom of the hole. The drill tool that is lowered into or pulled out of the hole can be used to drill cores, ore cores, rock cuttings, gas samples, liquid samples, etc., to explore the underground geology and mineral resources.

The drilling rig is prone to deflection due to the vibration of the drill bit and the impact of hard objects, or because the drilling rig is generally used for exploration in the wild space without a flat ground, the device lacks a horizontal detection device when it is used, so the device is not placed horizontally, making the drilling rig itself prone to deflection, which indirectly causes the drill hole of the drill rod to tilt, and the anti-tilt effect is not ideal.

To this end, the utility model provides a hole deflection prevention device for a drilling rig to solve the above-mentioned problem.
