Description

Technical Field

[0001] The invention specifically relates to the technical field of underground anchor support equipment in coal mines, in particular to a single-working-position automatic anchor drilling machine. Background Art

[0002] With the continuous improvement of the intelligence level of coal mines and the continuous promotion of technologies such as intelligent rapid excavation, the speed of mine excavation has been greatly improved, and the level of intelligent excavation has also been greatly improved. As one of the construction processes that consumes the longest man-hours in the excavation process, bolt support construction has reduced the impact of bolt support construction on the efficiency of tunnel excavation to a certain extent by adopting a large number of bolt drills in parallel and some bolts lagging support. However, with the use of a large number of bolt drills, the contradiction between the small number of people and the large number of equipment to be operated in coal mines has become prominent. Some coal mine underground excavation teams have repeatedly encountered the problem of a large number of equipment and a serious shortage of operators.

[0003] In order to solve the above problems, various automatic anchor drilling rig technologies have been developed successively. According to the switching method of drill rod and anchor rod, they can be mainly divided into two main technical routes: drill rod anchor rod double working position rotation switching, and drill rod anchor rod double working position balance switching. Both of the above routes require three working positions, one of which is the working position. This method results in a relatively large size of the drilling rig, making it difficult to arrange the drilling rig on various complete equipment, and poor adaptability in coal mines.

[0004] Another type of single-station drilling rig uses a threaded connection between the drill rod and the drill box to solve the problem that the drill rod is prone to falling off after being loaded during drilling. At the same time, due to the thread size restrictions on the drill rod and the drill box, the threads of the drill rod and the drill box require high precision during docking, which is prone to low thread docking success rates in actual applications. In addition, the drilling rig connection process is complex, time-consuming, and inefficient. Secondly, because the drill box needs to be connected to the drill rod in the form of a threaded output shaft, the nut connection between the drill box and the anchor cannot be used in the application of the automatic anchor drilling rig, resulting in the drilling rig being unable to install anchors without manual operation.
