Description

Technical Field

[0001] The invention belongs to the technical field of anchor support, and in particular relates to a swing anchor magazine and an automatic anchor drilling rig. Background Art

[0002] With the continuous improvement of coal mine intelligence and the continued promotion of technologies such as intelligent rapid tunneling, mine excavation speed has been greatly improved, and the level of intelligent tunneling has also been greatly improved. Anchor support construction, one of the most time-consuming construction processes during tunneling, has been reduced to a certain extent by adopting a method of parallel operation of a large number of anchor drills and delayed support of some anchors. However, the use of a large number of anchor drills has highlighted the contradiction between the small number of people working underground in coal mines and the large amount of equipment required for operation. Some underground tunneling teams in coal mines have repeatedly encountered the problem of a large number of equipment and a severe shortage of operators.

[0003] To solve the above problems, some domestic manufacturers have developed automatic anchor drilling rigs, which are generally controlled by programs and have the function of completing the drilling, charging, and anchor installation processes with one click. During use, after each 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] Single-cycle automatic anchor drilling rigs feature a dual-station design with a drill box and anchor box. They do not have a dedicated anchor magazine. Before work begins, a bolt is manually installed in the anchor box. During operation, after drilling and other preparatory work is complete, the bolt is installed in the anchor box. To begin the next bolting operation, the rig must be stopped and manually installed before another bolt can be installed. This method is suitable for applications where the anchoring workload is small and speed is not a priority, but safety is a high priority.

[0005] Multi-cycle automatic anchor drilling rigs typically utilize a dual-station design with a drill box and anchor box, with two switching modes: translational sliding and rotational. An independent anchor silo is installed on the front or side of the rig. This silo has a large capacity, typically storing between eight and eighteen anchors. Its structure can be categorized into two types: chain-rotating and cylindrical-rotating. The chain-rotating anchor rod bin 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 a sprocket to rotate to the anchor box position. 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 rod bin consists of a rotatable central spindle and two anchor rod mounting discs fixed on the spindle. Anchor rod mounting clips are machined and installed at equal intervals on the anchor rod mounting discs. The spindle is driven by a motor and other mechanisms to achieve a fixed angle rotation. After the anchor rod is rotated to a certain position, a special manipulator grabs the anchor rod and takes it out of the anchor rod bin. Then the manipulator swings the anchor rod and places it 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
