Description

Technical Field

[0001] The present invention relates to the technical field of roadway anchoring during coal mine mining, and specifically to a fully automatic bolt support drilling arm. Background Technique

[0002] Bolts are the most basic components of roadway support in contemporary coal mines. They reinforce the surrounding rock of the roadway together, enabling the surrounding rock to support itself. Bolts are not only used in mines but also in engineering technology to reinforce the main bodies of slopes, tunnels, and dams. As a tension member that penetrates deep into the formation, one end of the bolt is connected to the engineering structure, and the other end penetrates deep into the formation. The whole bolt is divided into a free section and an anchorage section. The free section refers to the area that transmits the tension at the bolt head to the anchor body, and its function is to apply prestress to the bolt.

[0003] In underground coal mine operations, bolt support is one of the key measures to ensure the stability of roadways. Traditional bolt support processes require workers to manually operate drilling equipment, convey anchoring agents, install bolts and perform stirring and other processes.

[0040] The clamping assembly 6 includes a push plate 64. As Figure 5 shown in the connection structure of the clamping assembly 6, the top of the push plate 64 is respectively hinged with a first clamping jaw 61 and a second clamping jaw 62.

[0041] The anchoring assembly 7 includes two connecting frames 71 and a second clamping mechanism. One side of the connecting frame 71 is fixed with a third motor 73. A turntable 74 is rotatably connected between the connecting frames 71. A number of second limiting grooves 76 are formed on the surface of the turntable 74. An anchor rod 72 is placed inside the second limiting grooves 76. Two rollers are rotatably connected to the inner wall of the second limiting grooves 76, and the rollers are used to contact the anchor rod 72 and assist its movement. One end of the anchor rod 72 is hexagonal. As Figure 9 and Figure 10 , it is the installation of the anchor rod 72.

[0042] The second clamping mechanism includes a fourth motor 77. The output shaft end of the fourth motor 77 is fixed with two fourth clamping plates 78. One side of the fourth clamping plate 78 is hinged with a third clamping plate 75. One side of the fourth clamping plate 78 is hinged with a sixth hydraulic cylinder 79. The push rod end of the sixth hydraulic cylinder 79 is hinged to one side of the third clamping plate 75. One side of the fourth motor 77 is fixed to one side of the connecting frame 71. One side of the connecting frame 71 is fixed to one side of the base 1. In this embodiment, all hydraulic cylinders are connected to a hydraulic station.

[0043] The lifting assembly 2 includes a box body 21. A first limiting groove 24 is formed in the inner wall of the box body 21. A first hydraulic cylinder 23 is installed at the bottom of the inner wall of the first limiting groove 24. The push rod end of the first hydraulic cylinder 23 is fixed with a support plate 22 installed at the bottom of the base 1. The push rod end of the first hydraulic cylinder 23 extends to different heights, enabling the drill arm at the top of the base 1 to be at different heights, so as to support the anchor rod 72 at different positions.

[0044] Working principle: When six processes of drilling, withdrawing the drill, feeding the anchoring agent, installing the anchor rod 72, stirring, and pre-tightening are required for the underground anchor rod 72 support process, only the push rod end of the first hydraulic cylinder 23 needs to be controlled to extend. The push rod end extends to different heights, pushing the support plate 22 to different heights. At this time, the drill arm at the top of the base 1 is at different heights, and the anchor rod 72 can be supported at different positions. At this time, the first motor 3 is on the side away from the clamping assembly 6, and this is the original position; the push rod end of the fifth hydraulic cylinder 63 retracts, causing the first clamping jaw 61 and the second clamping jaw 62 to approach each other, so that the holes of the first clamping jaw 61 and the second clamping jaw 62 assist in supporting during the drilling of the drill rod 55.

[0045] First, control the push rod end of the second hydraulic cylinder 4 to extend. The push rod end pushes the push plate 64 to extend and press against the coal wall. The output shaft of the second motor 51 drives the rotating shaft 54 to rotate counterclockwise, so that the drill rod 55 is located on the side of the inner hexagonal groove interface of the first motor 3. There is a guiding inclined surface on the side of the inner hexagonal groove interface. At the same time, the linear motor drives the first motor 3 to slowly approach the drill rod 55. The hexagonal end of the drill rod 55 is inserted into the inner side of the inner hexagonal groove interface. At this time, the first motor 3 and the linear motor work simultaneously, so that the inner hexagonal groove interface is inserted between the first clamping jaw 61 and the second clamping jaw 62, and the drill rod 55 rotates to drill the coal wall. After the drilling is completed, the first motor 3 stops rotating, and the linear motor starts to drive the first motor 3 and the drill rod 55 to retreat to a position convenient for subsequent operations. The second motor 51 drives the first clamping mechanism to rotate. The push rod end of the fourth hydraulic cylinder 58 retracts, causing the first clamping plate 52 to leave the side of the second clamping plate 57. When the first clamping plate 52 and the second clamping plate 57 are respectively on both sides of the drill rod 55, control the push rod end of the fourth hydraulic cylinder 58 to extend, so that the first clamping plate 52 and the second clamping plate 57 clamp the drill rod 55.

[0046] At this time, the push rod end of the fifth hydraulic cylinder 63 extends, causing the first clamping jaw 61 and the second clamping jaw 62 to move away from each other;

[0047] Subsequently, the linear motor drives the first motor 3 to move to the original position, so that one end of the drill rod 55 leaves the inner hexagonal groove interface of the first motor 3. At this time, the second motor 51 continues to rotate. The second motor 51 drives the rotating shaft 54 to rotate, so that the conveying pipe 56 is located on one side of the hole drilled by the drill rod 55. The push rod end of the third hydraulic cylinder 53 extends, so that one end of the conveying pipe 56 is inserted inside the drilled hole. Under the action of the anchoring agent spraying device, the anchoring agent is conveyed to the inside of the drilled hole. After the anchoring agent is conveyed, the output shaft of the second motor 51 drives the rotating shaft 54 to rotate clockwise, so that the drill rod 55 and the conveying pipe 56 leave one side of the first motor 3;

[0048] The output shaft of the third motor 73 drives the turntable 74 to rotate. At this time, the push rod of the sixth hydraulic cylinder 79 retracts, so that the second limiting groove 76 where the bolt 72 is placed moves to one side of the second clamping mechanism. The push rod end of the sixth hydraulic cylinder 79 extends, pushing the third clamping plate 75 to move towards the fourth clamping plate 78, so that the third clamping plate 75 and the fourth clamping plate 78 clamp the bolt 72. The output shaft of the fourth motor 77 drives the second clamping mechanism to rotate, and the second clamping mechanism drives the bolt 72 to move to one side of the first motor 3. At the same time, the linear motor drives the first motor 3 to slowly approach the bolt 72, so that one end of the bolt 72 with a hexagonal shape is inserted inside the inner hexagonal groove interface. The linear motor drives the first motor 3 to move towards the inside of the drilled hole sprayed with the anchoring agent. One end of the bolt 72 has been inserted inside the drilled hole. As the first motor 3 continues to rotate, the bolt 72 stirs the anchoring agent in the drilled hole, and at the same time inserts the bolt 72 inside the drilled hole. After the anchoring agent solidifies, the linear motor drives the first motor 3 to return to the original position. At this time, the support drill arm operation of the bolt 72 can be completed automatically;

[0049] Repeat the above steps to support the next bolt 72.

[0050] In summary, by controlling the push rod end of the first hydraulic cylinder 23 to extend to different heights, the drill arm on the top of the base 1 can be at different heights, so as to support the bolt 72 at different positions, realizing precise operation. The coordinated cooperation of each hydraulic cylinder, motor and linear motor ensures the accuracy and stability of the actions of each process.

[0051] Through the cooperation of components such as motors, linear motors, and grippers, in the drilling process, the automatic docking, drilling, and detachment of the drill rod 55 are realized; in the process of feeding the anchoring agent, the conveying pipe 56 can be accurately inserted into the drill hole; in the process of installing the bolt 72 and stirring, the bolt 72 can be accurately docked and the stirring operation can be completed. The cooperation between materials and tools in the whole process is efficient, reducing the waiting time between processes. The six processes of drilling, withdrawing the drill, feeding the anchoring agent, installing the bolt 72, stirring, and pre-tightening of the bolt 72 support are all automated without manual intervention, greatly improving the work efficiency, reducing the labor cost and labor intensity. The bolt 72 support process can be remotely operated by workers, keeping workers away from the dangerous underground operation site, effectively improving the labor safety of workers and reducing the accident risk.
