The telescopic assembly 4 comprises a plunger shaft 41 and a second driving part 42, the plunger shaft 41 and the second driving part 42 are both arranged on the base 1, the front end of the plunger shaft 41 is in sliding fit in the first passage 211, a second driving part is connected with the plunger shaft 41 and used for driving the plunger shaft 41 to move along the length direction of the first passage 211, a second passage 411 penetrates through the plunger shaft 41, the second passage 411 is communicated with the through hole 321 through the first passage 211, a check assembly 5 is arranged in the second passage 411, and the check assembly 5 can enable liquid to flow in one direction only along the direction (from back to front direction in fig. 2) of the second passage 411 towards the through hole 321.
As shown in fig. 6, the check assembly 5 includes a valve body 51, a magnetic valve core 52 and a magnetic member 53, the magnetic valve core 52 and the magnetic member 53 are disposed in the valve body 51, the magnetic valve core 52 is changeable between a first position and a second position, and when the magnetic valve core 52 is located at the first position, the magnetic valve core 52 is adsorbed on the magnetic member 53 to block the second channel 411; when the magnetic valve element 52 is located at the second position, the magnetic valve element 52 is separated from the magnetic member 53 to communicate with the second passage 411.
As shown in fig. 6, when the fluid flows along the second passage 411 toward the through hole 321 during operation of the bolting work equipment, the pressure of the fluid overcomes the magnetic force of the magnetic valve core 52 and the magnetic member 53 and then blows the magnetic valve core 52 and the magnetic member 53 apart, so that the second passage 411 is conducted. When no liquid flows through the second channel 411 or the liquid flows in the reverse direction, the second channel 411 can be closed due to the limiting effect of the magnetic valve core 52 and the magnetic element 53, so as to avoid the backflow of the liquid.
According to the anchor bolt support construction equipment provided by the embodiment of the invention, when the anchor bolt 32 is in drilling construction, liquid can be injected into the drilled hole through the second channel 411 so as to cool the anchor bolt 32 and facilitate the discharge of slag and scraps in the drilled hole; after the drilling is finished, an anchoring agent can be injected into the drilling hole through the second channel 411, and then the anchor rod assembly 3 is pre-tightened through the rotating shaft 21, so that the anchor rod support construction equipment can realize multiple steps in a roadway anchor rod support process, the labor intensity of workers is reduced, the roadway support efficiency is improved, the cost is low, the structure is simple, and the installation and maintenance are convenient.

When the magnetic valve core 52 is located at the first position, the blocking part 521 is adsorbed on the magnetic member 53, so that the magnetic valve body 51 and the magnetic member 53 form a circular line seal, and the liquid backflow phenomenon during the operation of the anchor bolt support construction equipment is further avoided.
Alternatively, as shown in fig. 2 and 5, the number of the second passages 411 is plural, the number of the check members 5 is plural, and the number of the check members 5 corresponds one-to-one to the number of the second passages 411, for example, the number of the second passages 411 is three, wherein a first second passage 4111 is connected to a pipe for pumping water, a second passage 4112 is connected to a pipe for pumping the a-component of the two-component anchoring agent, and a third second passage 4113 is connected to a pipe for pumping the B-component of the two-component anchoring agent.

The first sealing member 61 is disposed between the preload nut 31 and the first passage 211, and the second sealing member 62 is disposed between the plunger shaft 41 and the first passage 211, so that when the bolting work equipment according to the embodiment of the present invention performs drilling, it is possible to ensure that all of the high-pressure water flows into the through hole 321 in the bolt 32, thereby preventing leakage of liquid.
In some embodiments, as shown in fig. 1 to 3, the telescopic assembly 4 further includes a bracket 43 and an adjusting sleeve 44, the bracket 43 is disposed on the base 1, the plunger shaft 41 is slidably engaged with the bracket 43 and the adjusting sleeve 44, the adjusting sleeve 44 is connected with the bracket 43, and the position of the adjusting sleeve 44 along the length direction of the plunger shaft 41 is adjustable, it can be understood that, since the plunger shaft 41 is slidably engaged with the bracket 43, the plunger shaft 41 does not rotate relative to the rotating shaft 21, and since the position of the adjusting sleeve 44 along the length direction of the plunger shaft 41 is adjustable, the telescopic stroke of the plunger shaft 41 can be controlled by adjusting the position of the adjusting sleeve 44. For example, the adjustment sleeve 44 is threadedly coupled to the bracket 43, so that the relative position of the plunger shaft 41 and the bracket 43 can be adjusted by rotating the adjustment sleeve 44.
In some embodiments, as shown in fig. 1 to 3, the first driving member 22 includes a first transmission member 221, a second transmission member 222 and a first driver 223, the first transmission member 221 is coaxially connected with the first driver 223, the first transmission member 221 is in transmission fit with the second transmission member 222, and the second transmission member 222 is coaxially connected with the rotating shaft 21. For example, the first transmission member 221 and the second transmission member 222 are both gears.
Optionally, the first driver 223 is at least one of an electric motor, a hydraulic motor, a cylinder, and an internal combustion engine. For example, the first driver 223 is a hydraulic motor. Alternatively, the second drive member 42 comprises a second driver 421 and a third transmission member 422, the third transmission member 422 being mounted on a side wall of the plunger shaft 41, and the third transmission member 422 being connected to the second driver 421. The second driver 421 is at least one of an electric cylinder, an air cylinder, and a linear hydraulic motor, for example, the second driver 421 is a linear motor.
As shown in fig. 1 to 6, the working principle of the bolting work equipment according to the embodiment of the invention is 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 anchor rod support construction equipment of the embodiment of the invention is consistent, so that the details are not repeated.
