Description

Technical Field

[0001] The invention belongs to the technical field of anchor support, and in particular relates to 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 double working position design of a drill box working position and an anchor box working position. It does not have a separate storage bin. Before starting work, an anchor is manually installed on the anchor. During work, after completing the preparation work such as drilling, the anchor installed on the anchor box working position is installed. If the next anchor needs to be constructed, the machine needs to be stopped and another anchor needs to be manually installed on the anchor box working position 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-workstation design of a drill box workstation and an anchor box workstation, which is divided into two workstation switching methods: translation sliding switching and rotation switching. An independent storage bin will be installed on the front or side of the drilling rig body. The storage bin has a large capacity, and the general storage capacity is between eight and eighteen anchors. The structure of the storage bin can be basically divided into two types: chain rotation type and cylindrical rotation type. The chain rotation storage bin uses a special chain to form a closed loop, and multiple sets of clips for fixing anchors are made and installed on the chain. Each set of clips can install an anchor, and the chain is driven by the sprocket to rotate to the anchor box position. The anchor is pushed to the axis of the anchor box by a special manipulator to complete the installation of the anchor. The cylindrical rotary storage bin consists of a rotatable central spindle and two anchor bolt installation discs fixed on the spindle. Anchor bolt installation buckles are machined and installed at equal intervals on the anchor bolt installation discs. The spindle can rotate at a fixed angle under the promotion of motors and other mechanisms. After the anchor bolt is rotated to a certain position, a special manipulator grabs the anchor bolt and takes it out of the storage bin. Then the manipulator swings the anchor bolt to the center line position of the anchor box to complete the installation of the anchor bolt. Of the above two types of storage bins, the chain storage bin is installed on the front of the anchor drilling rig. Although the thickness dimension is small, the width dimension is large and fixed to the anchor drilling rig body, which makes the drilling rig inconvenient to repair and maintain. 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 weight. The cylindrical rotary storage bin also has problems such as excessive size and weight. An automatic anchor drilling rig with integrated drill box working station and anchor box working station has a complex structure, many movements, high requirements for processing and manufacturing, and a high failure rate.

A back plate 4.6 is connected by a first pin shaft, and a bending plate is provided at the other end. The tool rod is pushed so that the top end of the tool rod contacts the bending plate to push the movable baffle 4.3 to rotate along the first pin shaft, so that a groove suitable for a tool rod to pass through is formed between the first top plate 4.5 and the first side plate 4.2 close to the side of the movable baffle 4.3. One end of the first elastic member 4.4 is connected to the movable baffle 4.3, and the other end is connected to the first back plate 4.6; the first bottom plate 4.1, the first side plate 4.2 and the frame assembly 3.2 have the same width, the width of the bending plate is the same as the width of the first top plate 4.5, and the width of the first top plate 4.5 is greater than the width of the first bottom plate 4.1.

[0047] Among them, the upper limit assembly 4 is a welded frame structure, the first bottom plate 4.1 is connected to the top of the frame 3 by bolts, the movable baffle 4.3 is a thin plate bending structure, the top of which is set as a bending plate with a V-shaped groove, and the movable baffle 4.3 is set on the side close to the main frame 11, the width of the bending plate is the same as the width of the first top plate 4.5, and is larger than the width of other parts of the frame structure, so that the top of the tool rod can contact the inner side of the bending plate and the first top plate 4.5, when the tool rod is subjected to the feed force, it moves upward and contacts the bending plate, so as to push the bending plate to drive the entire movable baffle 4.3 to tilt open, so that the tool rod can pass through the slot formed between the first top plate 4.5 and the first side plate 4.2, thereby realizing drilling, charging and installation, and when the tool rod is withdrawn, the movable baffle 4.3 is driven by the first elastic member 4.4 to return to the initial position.

[0048] Further, see Fig. 9 and Fig.10 As shown, the storage bin also includes a lower limit assembly 10, which is arranged at the bottom of the frame assembly 3.2, and its bottom is abutted against the bottom end of the tool rod. The lower limit assembly 10 includes a second bottom plate 10.6, a second side plate 10.7, a second top plate 10.1 and a second back plate 10.2 that can form a frame structure; the second bottom plate 10.6 is provided with an arc groove at a position corresponding to the movable baffle 4.3, and the bottom of the arc groove is hingedly connected with a swing baffle 10.4, and the side of the swing baffle 10.4 is suitable for contacting with the drill box 12 and being pushed to realize the tool rod and the drill box 12. Docking; the arc groove is suitable for a tool rod to pass through, and an opening is provided on the second side plate 10.7 close to the main frame 11, and the opening is arranged close to the second bottom plate 10.6; a second elastic member 10.5 is also arranged at the bottom of the second bottom plate 10.6, one end of the second elastic member 10.5 is hingedly connected to the second bottom plate 10.6, and the other end is hingedly connected to the swing baffle 10.4; the second side plate 10.7, the second top plate 10.1 and the frame assembly 3.2 have the same width, and the width of the second bottom plate 10.6 is greater than the width of the second side plate 10.7 and the second top plate 10.1.

[0049] Specifically, the lower limit assembly 10 is a frame structure, and a circular arc groove is provided on the second bottom plate 10.6 near the main frame 11.
