Abstract
Description
Technical Field
[0001] This utility model relates to the field of building cleaning technology, and in particular to a system for cleaning the walls of inclined shaft tunnels. Background Technology
[0002] In the construction of inclined shaft tunnels, cleaning the tunnel walls is a crucial step in ensuring construction safety and quality. After the inclined shaft is excavated, due to geological conditions, blasting vibrations, and mechanical operations, the tunnel surface often accumulates a large amount of dust, mud, and loose gravel. These loose gravel particles have extremely poor stability and are prone to sudden detachment under construction vibrations or changes in ambient temperature. This can lead to minor issues such as clogging the drainage system and damaging construction equipment, or even serious collapses, severely threatening the safety of personnel working underground.
[0003] Currently, the industry commonly uses manual suspended operation to clean the walls of inclined shaft tunnels: workers are suspended from the shaft wall by safety ropes, use manual tools (such as steel chisels and hammers) to knock down loose rocks, and sweep away dust with brooms. This method has several drawbacks: 1. The inclined shaft has a large slope, and workers are prone to falling due to physical exhaustion or equipment failure during long-term suspended operation; at the same time, knocking down rocks may trigger a chain reaction of falling rocks, causing secondary injuries; 2. The speed of manual cleaning is limited by the physical strength of the workers, and on average, only 10-15 meters of shaft wall can be processed per shift, which is difficult to match the daily excavation progress of more than 50 meters in large-scale projects; 3. The dust concentration is consistently above the standard, and even if workers wear protective equipment, they still face occupational health risks such as pneumoconiosis.
[0004] Therefore, there is an urgent need for a machine that can replace manual labor in cleaning debris and dust from the walls of inclined shaft tunnels. In response to the above needs, this application is proposed. Utility Model Content

The cleaning efficiency is high, labor costs are saved, and the safety hazards caused by manual cleaning are avoided. Attached Figure Description
