Technical Field
[0001] The utility model belongs to the technical field of rock drills, in particular to a rock drill capable of measuring inclination angles. Background Art
[0002] The underground geological conditions of coal mines are complex, and the layout conditions of tunnels are diverse. Generally, after tunnel excavation, anchor beams and mesh cables are used to protect the tunnels. As the working face is mined, the anchor support parameters and inclination angles on the coal tunnel section will be different. When performing anchor support, the depth and inclination angle of the drilling holes of the rock drill are different. In order to improve the accuracy of the anchor support construction of underground coal tunnels, it is necessary to accurately control the underground inclined drilling construction.
[0003] The existing Chinese patent with publication number CN219299294U discloses a rock drill capable of measuring inclination. The inclination angle of the rock drill body can be obtained through the measuring surface on the outer wall of the protractor, so that the staff can monitor the inclination angle of the rock drill body in real time. The staff can also monitor the inclination angle of the rock drill body from the side, which is convenient for the operation needs of different staff members.
