Abstract

The invention provides a mechanical anchor drilling assembly. The mechanical anchor drilling assembly comprises two L-shaped brackets and a cross beam. The L-shaped brackets comprise vertical barrelsand horizontal barrels, and the vertical barrels and the horizontal barrels are perpendicularly connected; and the two ends of the cross beam are connected with vertical inner barrels correspondingly,and the vertical inner barrels are correspondingly inserted into the vertical barrels of the L-shaped brackets and slidably connected with the vertical barrels. The mechanical anchor drilling assembly is characterized in that a first sliding sleeve and a second sliding sleeve which are slidably connected with the cross beam are arranged on the cross beam in a sleeving mode, the first sliding sleeve and the second sliding sleeve are correspondingly and rotatably connected to one end of a rotary frame through a first rotation speed reducer, the other end of the rotary frame is rotatably connected with a supporting seat through a second rotation speed reducer, and the supporting seat is hinged to a roof bolter. According to the mechanical anchor drilling assembly, punching operating ranges can be increased, the penetration speed is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the field of coal mine machinery, in particular to a mechanical anchor-drill assembly for an airborne anchor-protection mechanism. Background technique [0002] The roadheader has been widely used in tunnel excavation projects such as mine tunnels and coal mine roadways. In the link of roadway excavation, except for the improvement of the quality of the roadheader itself, the overall technological level still maintains the level of the 1970s and 1980s. The speed of excavation is fast and the speed of support is slow, which seriously restricts the speed of excavation. In recent years, in order to increase the footage and increase the utilization rate of the roadheader, a variety of airborne anchor protection mechanisms have been developed, but the effect is not very satisfactory, the drilling range is limited, and only part of the mechanized operations of the anchor holes can be completed, and the rest are still needed. Manual ...
