Background
In the coal mine industry, when coal mining operation is carried out underground, drilling work such as water detection, gas detection, fault detection, water injection and the like needs to be carried out on a coal seam. Since the working site is constantly changed, the self-moving track is required to be operated by a deep hole drill carriage so as to drill holes in different places. However, even in the same underground location, the drilling angle and the drilling height are different, so that the drill rod needs to be rotated by a certain angle so as to be suitable for drilling in all directions, and meanwhile, the power head can move up and down along with the carriage assembly so as to be suitable for hole positions with different heights.
However, the carriage assembly of the working mechanism of the conventional coal mine drill carriage is driven by the side oil cylinder to rotate, so that the drilling angle of the drill rod is adjusted. The rotation angle between the piston rod of the oil cylinder and the sliding frame assembly is limited, and once the rotation is too large, the oil cylinder cannot support the sliding frame assembly, so that the working mechanism of the drill carriage can only rotate by 0-45 degrees, a low-position hole cannot be drilled, the drilling angle range of the drill carriage is limited, and the applicability of the drill carriage is poor.
