Description

Technical Field

[0001] The invention relates to the technical field of mining engineering support equipment, and more specifically to a coal mine support steel belt repairing device. Background Art

[0002] Coal mine support steel belt is cold-pressed from high-strength alloy plates. It is combined with various anchor rods to support the internal operation of coal mines. It is the best choice for controlling weak rocks and coal roofs. Coal mine support steel belt is widely used in tunnel support in underground mine working faces, caves and other fields, and is more effective in dealing with unstable surrounding rocks. However, in the long-term support process, the steel belt is prone to bending. The main deformation position is that the convex part further bulges outward due to the surrounding stress. Replacing it requires a lot of cost. In order to save costs, a repair device is usually used to repair the steel belt. The specific repair process is to press the bent part of the steel belt to a flat state. In the prior art, when the coal mine support steel belt repair device determines whether the steel belt is in a bent state, it is easy to judge if the degree of bending is large, but it is difficult to judge if the degree of bending is small, which is often based on experience and human judgment. Especially when repairing a longer steel belt, it is very laborious and laborious. This results in the steel belt being put into use directly without repairing the parts where the bending is not obvious, which affects normal use and is more likely to induce bending. In addition, the equipment for repairing the steel belt needs to be replaced and used separately, which is inefficient and inconvenient to locate. Summary of the invention
