Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a support for mine excavation. Background technique [0002] At present, the excavation support is a common equipment during mining in my country, and it is often used as a structure to control the pressure of the working face. At present, most of the fixed brackets used for excavation equipment are fixed in structure and inconvenient to adjust. After excavating to a certain position, the bracket needs to be manually disassembled and adjusted according to different directions and heights of excavation, which cannot be stable and effective. Mobile, structural stability is also insufficient, work efficiency is low, and labor intensity is big. Contents of the invention [0003] Aiming at the above prior art, the present invention provides a support for mine excavation that is easy to use, flexible to adjust, and can run stably without disassembly. [0004] To achieve sa...
