Description

Technical Field

[0001] The invention belongs to the technical field of anchor support, and in particular relates to a swing anchor bin and an 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 in coal mines and the large number of equipment to be operated has become prominent again. Some coal mine underground excavation teams have repeatedly encountered the problem of a large number of equipment and a serious shortage of operators.

[0003] To solve the above problems, some domestic manufacturers have developed automatic anchor drilling rigs, which are generally automatically controlled by programs and have the function of completing drilling, charging, and anchor installation processes with one click. In use, every time an anchor is installed, it is necessary to add an anchor to the anchor installation position of the drilling rig before installing the next anchor. In existing automatic anchor drilling rigs, there are generally two ways to add anchors:

[0004] The single-cycle automatic anchor drilling rig adopts a dual-station design of a drill box station and an anchor box station. It does not come with a separate anchor barn. Before starting work, an anchor is manually installed at the anchor box station. During work, after completing the preparation work such as drilling, the anchor installed at the anchor box station is installed. If the next anchor needs to be constructed, the machine needs to be stopped and another anchor needs to be manually installed at the anchor box station before construction can continue. This method is suitable for occasions where the anchor construction workload is small and the construction speed requirement is not high, but the safety requirement is high.

[0005] Multi-cycle automatic anchor drilling rigs generally adopt a dual-working position design of a drill box working position and an anchor box working position, which is divided into two working position switching methods: translation sliding switching and rotation switching. An independent anchor bolt warehouse will be installed on the front or side of the drilling rig body. The anchor bolt warehouse has a large capacity, generally storing between eight and eighteen anchor bolts. The structure of the anchor bolt warehouse can basically be divided into two types: chain rotation type and cylindrical rotation type. The chain-rotating anchor barn uses a special chain to form a closed loop, and multiple sets of clips for fixing anchor rods are made and installed on the chain. Each set of clips can install one anchor rod, and the chain is driven by the sprocket to rotate to the anchor box position, and the anchor rod is pushed to the axis of the anchor box by a special manipulator to complete the anchor rod installation; the cylindrical rotary anchor barn consists of a rotatable central spindle and two anchor rod installation discs fixed on the spindle. Anchor rod installation clips are machined and installed at equal intervals on the anchor rod installation discs. The spindle can achieve fixed angle rotation under the drive of motors and other mechanisms. After the anchor rod is rotated to a certain position, a special manipulator grabs the anchor rod and takes it out of the anchor barn, and then the manipulator swings the anchor rod to the center line position of the anchor box to complete the anchor rod installation. Of the two types of anchor silos mentioned above, the chain-type anchor silo is installed on the front of the anchor drilling rig. Although it is relatively small in thickness, it is very large in width and is fixed to the body of the anchor drilling rig, which makes it inconvenient to repair and maintain the drilling rig. In special circumstances, it is difficult to use manual operation of the drilling rig to carry out anchor cable construction due to obstruction. At the same time, the drilling rig occupies a large space and weighs a large amount. The cylindrical rotary anchor silo also has problems such as excessive size and weight. Summary of the invention
