As shown in fig. 1 to 5, the multifunctional bolting construction equipment according to an embodiment of the present invention operates as follows:
(1) drilling holes
When the bolting operation cycle begins, the first driver 223 rotates forward to drive the first transmission member 221 to rotate forward, and the first transmission member 221 and the second transmission member 222 are engaged with each other, so that the second transmission member 222 rotates backward under the driving of the first transmission member 221. Since the second transmission member 222 is coaxially installed on the rotating shaft 21, the rotating shaft 21 is reversely rotated. The pre-tightening nut 31 at the rear end of the anchor rod 32 is connected with the rotating shaft 21, the anchor rod tail limiting block 35 is fixedly connected with the anchor rod 32, the anchor rod 32 and the rotating shaft 21 rotate together under the action of the anchor rod tail limiting block 35, and a drill bit at the head of the anchor rod 32 is used for drilling.
During the drilling process, because the inner side and the outer side of the second sealing element 62 respectively contact the rotating shaft 21 and the plunger shaft 41, the plunger shaft 41 is subjected to torque generated by friction force, and the plunger shaft 41 does not rotate under the action of the bracket 43, so that the plunger shaft 41 does not rotate along with the rotating shaft 21. The first second passage 4111 in the plunger shaft 41 delivers water to the head of the bolt 32 for removal of coal slag and cooling of the drill bit, and due to the action of the first and second seals 61, 62, it is ensured that a high pressure water flow enters the through bore 321 of the bolt 32 without leaking out. Specifically, as shown in fig. 4, the anchor bar assembly 3 includes: the anchor rod 32, the anchor rod tail limiting block 35, the pre-tightening nut 31, the self-aligning ball pad 33 and the tray 34 are sequentially arranged along the length direction of the anchor rod 32. When the hole is drilled to a specified depth or when the anchor rod tail limiting block 35 is tightly attached to the pre-tightening nut 31, the pre-tightening nut 31 is tightly attached to the aligning ball pad 33, the aligning ball pad 33 is tightly attached to the tray 34, and the tray 34 is tightly attached to the surrounding rock, the hole drilling is completed.
(2) Anchor grouting
After drilling is completed, the first driver 223 stops rotating, and the first second passage 4111 in the plunger shaft 41 stops pumping water into the through hole 321 of the anchor rod 32; the second passage 4112 and the third passage 4113 of the plunger shaft 41 transmit the component A and the component B of the anchoring agent respectively, the anchoring agent of the two components is transmitted to the through hole 321 of the anchor rod 32 and the gap between the anchor rod 32 and the surrounding rock at the same time, due to the action of the first sealing piece 61 and the second sealing piece 62, the component A and the component B of the anchoring agent can be ensured to enter the through hole 321 of the anchor rod 32 without leakage, after the anchoring agent is pumped to a preset amount, the pumping is stopped, and after the components of the anchoring agent are mixed and reacted, the anchoring function is realized.
(3) Pretightening
After the anchoring is finished and the anchoring agent is solidified, the first driver 223 rotates reversely, the pretightening nut 31 is driven to rotate through the first transmission piece 221 and the second transmission piece 222, the rotating direction of the pretightening nut 31 is opposite to the rotating direction in the drilling process, the pretightening nut 31 continuously extrudes the tray 34 tightly attached to the surrounding rock, and the pretightening of the anchor rod 32 is realized, and in the pretightening process, the anchor rod 32 translates relative to the rotating shaft 21 in the direction far away from the surrounding rock; when the first driver 223 rotates reversely, the second driver 421 starts to work, the second driver 421 drives the third transmission member 422 to translate towards the direction away from the surrounding rock, and because the third transmission member 422 is installed on the side wall of the plunger shaft 41, the third transmission member 422 drives the plunger shaft 41 to translate towards the direction away from the surrounding rock actively, so as to leave a space for pre-tightening the anchor rod 32 until the pre-tightening process is completed. After the pre-tightening is finished, the anchor rod 32 is separated from the rotating shaft 21, the second driver 421 works reversely, the plunger shaft 41 translates relative to the rotating shaft 21 and gradually returns to the original position, and the maximum distance of the plunger shaft 41 moving in the direction away from the surrounding rock can be adjusted through the plunger shaft 41 telescopic stroke adjusting block.
After the above process steps are completed, the next operation cycle is performed according to the construction requirements, and in each operation cycle, the working principle of the multifunctional anchor rod support construction equipment of the embodiment of the invention is consistent, so that the details are not repeated.
