AI Technical Summary
Technical Problem
Existing pneumatic anchor drilling rigs experience significant vibration fluctuations during drilling, leading to drill rod misalignment or slippage. Relying on worker experience makes it difficult to achieve standardized positioning during drilling.
Method used
Design a combined support device for a mine anchor drilling rig. The device uses gravity leveling, sliding plate, and three-point positioning. By aligning the mounting platform with the drill rod axis, a ball is used to abut the drill rod for radial limiting, reducing the impact of vibration.
Benefits of technology
It improves stability in the initial stage of drilling, reduces reliance on worker experience, enhances production standardization, and prevents borehole tilting.

Abstract
The present application relates to the technical field of mine operation, especially to a combined supporting device of a mine anchor rod drilling machine, comprising a circular mounting table, the center of gravity of the mounting table is always kept on the axis, the bottom of the mounting table is provided with a leveling structure to keep the mounting table in a horizontal state, a sleeve is fixedly connected to the middle of the upper end surface of the mounting table, the axis of the mounting table and the axis of the drill rod are kept coincident through gravity leveling, sliding of the sliding plate and three-point positioning, so as to balance the radial force of the drill rod caused by shaking during the drilling process of the drilling machine, maintain the stability of the drill rod during the cutting process, prevent the problem of hole inclination caused by large shaking amplitude in the initial drilling stage, reduce the dependence on the experience of workers during the drilling and eyeing process, and improve the standardization degree of production practice.
