Airborne anchor support mechanism

Abstract

The invention provides an airborne anchor support mechanism comprising a main telescopic arm, a temporary supporting mechanism and a mechanical anchor drilling assembly. The main telescopic arm comprises an outer cylinder and an inner cylinder, and the lower side of the outer cylinder is fixedly connected to a base frame. The inner cylinder is in sliding connection in the outer cylinder, and the upper side of the inner cylinder is fixedly connected with the temporary supporting mechanism. The mechanical anchor drilling assembly comprises an 'L'-shaped bracket. The 'L'-shaped bracket comprisesa vertical cylinder and a horizontal cylinder. The vertical cylinder and the horizontal cylinder are vertically connected, and the horizontal cylinder is in sliding connection in the inner cylinder. The inner cylinder is provided with a row spacing adjustment cylinder, one end of the row spacing adjustment cylinder is hinged to the inner cylinder, and the other end is hinged to the horizontal cylinder. The airborne anchor support mechanism can increase the drilling operation range, and improve the driving speed. The temporary supporting mechanism and the mechanical anchor drilling assembly areseparated, so that the temporary supporting can always effectively support the roadway stroke during multi-row construction operation, the operation safety is improved, the equipment utilization is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of coal mine machinery, in particular to 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 roadway excavation process, 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 excavation speed is fast and the support speed is slow. Due to the restriction of the empty head distance, the roadheader often has to stop after cutting a row distance to carry out bolt support. However, most of the bolt support methods in the prior art are completed by manual labor, which is labor-intensive and poor in operation safety. , there are also some roadways that use the integrated machine for digging, bolting and protecting to realize the construction of the top bolt and the middle and upper side.

Due to the restriction of the empty head distance, the roadheader often has to stop after cutting a row distance to carry out bolt support. However, most of the bolt support methods in the prior art are completed by manual labor, which is labor-intensive and poor in operation safety. , there are also some roadways that use the integrated machine for digging, bolting and protecting to realize the construction of the top bolt and the middle and upper side. The roadheader itself has a certain influence, and it cannot drill holes in the entire section, so that the entire anchor protection operation time is not significantly improved compared with manual work, and maintenance is difficult and the cost increases
