Description

Technical Field

[0001] The utility model belongs to the technical field of anchor rod removal, in particular to an anchor rod water cutting removal device. Background Art

[0002] Anchor rods are the most basic component of tunnel support in contemporary coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dams. As a tensile member that penetrates deep into the stratum, the anchor rod is connected to the engineering structure at one end and penetrates deep into the stratum at the other end. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body, and its function is to apply prestress to the anchor rod. The free section of the anchor rod usually uses an anchor rod tray and a nut to apply prestress to the anchor rod. After the nut is tightened, the anchor rod usually has a shorter length exposed from the nut.

[0003] During the production process underground in coal mines, the removal of the anchor rods on the tunnel roof is often difficult. This is because the nuts on the anchor rods need to be cut when the anchor rods are removed. However, the conditions underground in coal mines are relatively special, with hidden dangers of gas and coal dust. Gas cutting or traditional electric cutting tools will produce open flames or sparks, which poses a risk of explosion. In addition, the length of the anchor rods that is exposed to the nuts is usually short, making it impossible to reliably fix the cutting tools. Operators can only cut by hand, which results in unstable cutting and poor accuracy, which in turn causes safety issues during the cutting process. Utility Model Content
