Technical Field

[0001] This utility model relates to the field of mine roadway construction safety technology, specifically to an auxiliary device for safe construction of large-section roadways. Background Technology

[0002] In recent years, the situation regarding mine safety has become increasingly severe. Against this backdrop, mine construction urgently needs to improve production efficiency while ensuring safety, but existing technologies face multiple challenges.

[0003] First, the geological complexity: the hydrogeological conditions of underground mines are highly variable, and the construction of large-section roadways requires the use of short excavation and short support techniques, with frequent alternation between excavation and support, which complicates the work process. Second, the risks of working at height: as the roadway cross-section increases, the frequency of working at height, such as roof support and equipment installation, increases significantly. According to safety regulations, personnel must be reliably secured with safety belts, but traditional platforms lack dedicated anchor points, posing a risk of falls. Third, insufficient equipment adaptability: most existing auxiliary equipment is designed for fixed heights, making it difficult to flexibly match roadway cross-sections of different specifications (such as height and span), resulting in repeated disassembly and assembly, low transportation efficiency, and slowing down the construction progress.

[0004] While some adjustable work platforms exist, they still suffer from the following drawbacks: limited height adjustment range, failing to cover the diverse dimensions of large-section roadways; lack of integrated safety belt hoisting devices, requiring personnel to rely on temporary anchor points during high-altitude operations, violating the safety principle of high-hanging and low-use; and a bulky overall structure, requiring time-consuming assembly and disassembly, making it unsuitable for the rapid construction pace of short-short excavation and short-support operations.

[0005] Therefore, there is an urgent need for an auxiliary device that combines high adjustability, safety and compliance with regulations, and rapid assembly and disassembly capabilities to overcome the technical bottleneck of safe and efficient construction of large-section tunnels.
