Description

A kind of taphole opening machine with large rotation angle

Technical field

The invention relates to the technical field of furnace front equipment, and in particular to a large rotation angle tap opening machine.

Background technique

At present, the rotary mechanism of tap opening machines generally adopts plane rotation. When rotating to the working position, it is necessary to tilt the oil cylinder to press down the hook of the drilling rig feed mechanism before the rock drill punching function can be performed. The connection type between the hanging mechanism and the boom beam generally adopts the orifice plate connection type, which cannot realize the left and right adjustment of the drilling rig feed mechanism. Even if there is a control link, it can only make the drill bit at the front end of the drill feed mechanism rotate around. The center of the hanging part swings left and right, which prevents the entire drilling rig feed mechanism from moving left and right, and it is impossible to ensure that the drill pipe always coincides with the center line of the tap hole.

In order to allow the inclined column to ensure that the equipment is aligned with the taphole after one rotation, the Chinese utility model patent publication number CN218755839U discloses a foldable drawer-type inclined column type taphole opening machine, including a drilling rig feeding mechanism, Hanging mechanism, rotary cylinder and four-bar linkage mechanism. The taphole opening machine is driven by the rotary cylinder to rotate the cantilever, and the four-bar linkage mechanism can complete the folding, thereby reducing the rotation area.

The rotation area of the above-mentioned patent publications is small and cannot meet the needs of tapping openings with large working angles. In view of this, it is necessary to improve the taphole opening machine with a large rotation angle disclosed in the above patent document to meet the taphole opening requirements.
