Description

Technical Field

[0001] This utility model relates to the field of coal mill technology, specifically to a drilling rig for a coal mill. Background Technology

[0002] In the assembly and processing of coal mills, drilling rigs are needed to drill holes in the equipment components so that the coal mill body equipment can be riveted together. However, the coal mill body structure is complex and has irregular shapes and angles. Drilling rigs that operate at a single angle are difficult to meet the assembly and processing requirements of the coal mill body.

[0003] The irregular and non-standard structures and components of existing coal mills, such as the arc-shaped casing, inclined frame, and non-planar sheet metal, cannot be drilled on a single drilling machine, leading to difficulties in processing special-sized coal mills. Therefore, a drilling rig for coal mills is proposed, which provides a drilling mechanism with two drilling worktables for coal mill processing. It can perform simple vertical drilling operations and inclined drilling operations, greatly increasing the flexibility of coal mill drilling processing and expanding the drilling operation range of coal mills.

[0022] Specifically, the angle-adjusting drill unit includes:

[0023] An adjustable corner section is installed on the column;

[0039] The beneficial effects of this utility model are as follows: The assembly, consisting of a drilling section, a vertical drilling platform section, and an adjustable drilling platform section, provides a drilling mechanism with two types of drilling workbenches for coal mill processing.
