Description

Technical Field

[0001] The present invention relates to the technical field of drill pipe libraries of drill-anchor jumbo, and particularly relates to a modular split-type drill pipe library. Background Art

[0002] Most existing rock drilling jumbos do not have a drill pipe library, and the work of placing, retrieving, and connecting drill pipes during drilling operations needs to be completed manually, resulting in low work efficiency.

[0003] For some jumbos equipped with a drill pipe library, each type of drill pipe library corresponds to a single drill pipe length. When different lengths of drill pipes need to be replaced, the entire drill pipe library needs to be replaced, which also affects efficiency. At the same time, due to the large volume and heavy weight of the drill pipe library, the operation risk increases during overall replacement. Since different lengths of drill pipe libraries are not interchangeable, the variety of drill pipe libraries is large, increasing the manufacturing cost. Summary of the Invention
