As shown in fig. 1 to 5, the working principle of the multifunctional anchor bolt support construction equipment according to the embodiment of the present invention is as follows:
(1) Drilling holes
The anchor bolt supporting operation cycle starts, the first driver 223 rotates forward to drive the first transmission piece 221 to rotate forward, and the second transmission piece 222 rotates reversely under the drive of the first transmission piece 221 because the first transmission piece 221 and the second transmission piece 222 are meshed with each other. Since the second transmission member 222 is coaxially installed on the rotation shaft 21, the rotation shaft 21 is reversed. The pretension 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 drilling is conducted through a drill bit at the head of the anchor rod 32.
During the drilling process, since the inner and outer sides of the second sealing member 62 respectively contact the rotating shaft 21 and the plunger shaft 41, the plunger shaft 41 receives torque generated by friction, 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 passage 4111 in the plunger shaft 41 delivers water to the head of the anchor rod 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, high pressure water flow into the through bore 321 of the anchor rod 32 is ensured without leakage. Specifically, as shown in fig. 4, the anchor rod assembly 3 includes: the anchor rod 32, the anchor rod tail limiting block 35, the pre-tightening nut 31, the aligning ball pad 33 and the tray 34, wherein the anchor rod tail limiting block 35, the pre-tightening nut 31, the aligning ball pad 33 and the tray 34 are sequentially arranged along the length direction of the anchor rod 32. When the drilling is carried out to the designated depth or when the bolt 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 drilling is completed.
(2) Anchor injection
After the drilling is completed, the first driver 223 stops rotating, and the first second channel 4111 in the plunger shaft 41 stops pumping water into the through hole 321 of the anchor rod 32; the second channel 4112 and the third channel 4113 of the plunger shaft 41 respectively transmit the a component and the B component of the anchoring agent, the anchoring agents of the two components are simultaneously transmitted into the through hole 321 of the anchor rod 32 and the gap between the anchor rod 32 and the surrounding rock, the a component and the B component of the anchoring agent can be ensured to enter the through hole 321 of the anchor rod 32 without leakage due to the effect of the first sealing element 61 and the second sealing element 62, the pumping of the anchoring agent is stopped after the preset amount of the anchoring agent is pumped, and the anchoring function is realized after the mixing reaction of the components of the anchoring agent.
(3) Pretension
After the anchoring is finished and the anchoring agent is solidified, the first driver 223 reverses, the first transmission piece 221 and the second transmission piece 222 drive the pre-tightening nut 31 to rotate, at the moment, the rotation direction of the pre-tightening nut 31 is opposite to the rotation direction of the drilling process, the pre-tightening nut 31 continuously extrudes a tray 34 tightly attached to surrounding rock, pre-tightening of the anchor rod 32 is realized, and the anchor rod 32 translates in a direction away from the surrounding rock relative to the rotating shaft 21 in the pre-tightening process; while 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 in the direction away from the surrounding rock, and as the third transmission member 422 is arranged on the side wall of the plunger shaft 41, the third transmission member 422 drives the plunger shaft 41 to translate in the direction away from the surrounding rock actively, so that a space is reserved 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 moves horizontally relative to the rotating shaft 21 and gradually returns to the original position, and the maximum distance of the plunger shaft 41 moving away from the surrounding rock can be adjusted through the telescopic stroke adjusting block of the plunger shaft 41.
After the above process steps are completed, the next working cycle is performed according to the construction requirement, and in each working cycle, the working principle of the multifunctional anchor bolt support construction equipment in the embodiment of the invention is consistent, so that the description is omitted.
