Description

Technical Field

[0001] The present invention relates to the technical field of surrounding rock grouting, and particularly to an intelligent monitoring device for deep surrounding rock grouting. Background Art

[0002] Surrounding rock grouting is a reinforcement technique that injects slurry into the surrounding rock to improve the structural integrity and bearing capacity of the surrounding rock. During the grouting operation, it is necessary for the staff to regularly prepare slurry test blocks to facilitate the monitoring of the performance of the injected slurry by the construction personnel.

[0003] A patent document with the application number CN2022113284788 and the publication date of October 17, 2023 discloses a grouting device and a grouting method thereof, which relates to the technical field of structure support grouting. The main purpose is to solve the problem that the existing grouting equipment is not suitable for mobile grouting at the construction site, and the grouting volume cannot be accurately controlled during manual grouting, resulting in increased construction difficulty and affecting the efficiency and quality of the grouting process. The main technical solution of the present invention is: a grouting device for performing grouting operations through air pressure; a pressure monitoring device disposed on the top of the grouting device to monitor the air pressure inside the grouting device in real time during the grouting operation; a moving device for loading the grouting device to move and adjust the grouting position during the grouting operation.

[0004] Although this grouting equipment can perform grouting operations, during the working process, the construction personnel still need to manually operate the grouting pipe to inject the slurry in the grouting pipe into the inside of the test block shell, so as to prepare the slurry test block. In this process, it is not only time-consuming and laborious, but also the test block shell after injecting the slurry needs to be manually carried by the construction personnel into the corresponding storage container, and the process is extremely cumbersome. Therefore, we propose an intelligent monitoring device for deep surrounding rock grouting. Summary of the Invention

[0005] To solve the technical problem of the poor existing monitoring method for surrounding rock grouting, the present invention provides an intelligent monitoring device for deep surrounding rock grouting.

One end of the slurry output pipe 2 away from the electromagnetic three-way valve 1 is installed with a grouting pipe. One side of the electromagnetic three-way valve 1 is provided with a housing, and the housing is provided with a cavity 1 and a cavity 2. One end of the slurry output pipe 3 away from the electromagnetic three-way valve 1 is installed with an electromagnetic three-way valve 2 fixed outside the housing.

Connect the tail end of the slurry input pipe 1 to the slurry conveying equipment, and convey the slurry to the inside of the slurry output pipe 2 through the slurry input pipe 1. The slurry entering the inside of the slurry output pipe 2 is ejected through the grouting pipe. At this time, the slurry ejected through the grouting pipe performs grouting operation on the surrounding rock. When it is necessary to prepare a slurry test block, the slurry inside the slurry input pipe 1 can be conveyed to the inside of the slurry output pipe 3 through the operation of the electromagnetic three-way valve 1, and the slurry can be conveyed to the inside of the slurry output pipe 4 or the slurry output pipe 5 through the operation of the electromagnetic three-way valve 2.

A hydraulic cylinder one 36 with a piston end fixed on the rack plate one 35 is fixed to the inner wall of the chamber one 46. The mounting block 10 rotates inside the chamber one 46. A base 11 is rotatably connected inside the mounting block 10. A plurality of test block shells 12 are fixed to the outside of the base 11. The test block shell 12 located below the slurry output pipe four 8 corresponds to the end of the slurry output pipe four 8. The test block shell 12 located below the slurry output pipe five 9 corresponds to the end of the slurry output pipe five 9. A driving column is fixed at the midpoint of the side of the base 11 away from the test block shell 12. A gear two is fixedly sleeved on the outer wall of the driving column. A rack plate two 14 that meshes with the gear two is arranged outside the gear two. The rack plate two 14 slides inside the mounting block 10. A hydraulic cylinder two 15 with a piston end fixed on the rack plate two 14 is fixed to the inner wall of the mounting block 10. A baffle 45 for closing the opening of the test block shell 12 is arranged on the side of the base 11 away from the mounting block 10. An installation frame 28 is fixed to the side of the mounting block 10 away from the base 11. The mounting block 10 is provided with a plurality of sliding holes corresponding to the test block shells 12. A sliding column 22 is slidably inserted through the inside of the sliding hole. A sliding plate 24 is slidably connected inside the installation frame 28. The end of the sliding column 22 located inside the installation frame 28 is fixed to the sliding plate 24. A plurality of through holes one are opened in the test block shell 12. A plurality of through holes two 21 corresponding to the through holes one are opened in the base 11. The end of the sliding column 22 away from the sliding plate 24 is slidably matched with the corresponding through hole one and through hole two 21. A backing plate 13 is slidably connected inside the test block shell 12. A linkage column 25 that is slidably inserted through the inside of the through hole one and through hole two 21 is fixed to the side of the backing plate 13 away from the baffle 45. A sliding groove 26 is opened on the outer side of the linkage column 25. A sliding block 27 fixed to the inner wall of the through hole one is slidably connected inside the sliding groove 26. A transfer column 29 is arranged on the side of the sliding plate 24 away from the sliding column 22. A plurality of cams 30 that cooperate with the sliding plate 24 are fixedly sleeved on the outer wall of the transfer column 29. The cams 30 rotate inside the installation frame 28. One end of the transfer column 29 is rotatably connected to the inner wall of the installation frame 28. The other end of the transfer column 29 penetrates to the outside of the installation frame 28. Transmission wheels 31 are fixedly sleeved on the outer walls of the transfer column 29 located outside the installation frame 28 and the adjacent rotating column 33.An external part of the driving wheel 31 is provided with a transmission belt 32 that is in transmission cooperation with the driving wheel 31. A bearing plate 44 is fixed to the inner wall of the first chamber 46. When preparing a slurry test block, by the displacement of the baffle 45, the opening of the test block shell 12 is opened. Through the fifth slurry output pipe 9, the slurry inside the fifth slurry output pipe 9 can be transported to the corresponding test block shell 12. When the test block shell 12 near the fifth slurry output pipe 9 is filled with slurry, through the operation of the second hydraulic cylinder 15, the second rack plate 14 can be driven to displace, driving the driving column to rotate, driving the base 11 to rotate, driving the test block shell 12 on the base 11 to rotate. When the test block shell 12 without loaded slurry rotates below the fifth slurry output pipe 9, an adequate amount of slurry can be transported to the corresponding test block shell 12 through the fifth slurry output pipe 9. After that, the above operations can be repeated until all the test block shells 12 are loaded with slurry. When the slurry inside the test block shell 12 solidifies and the test block inside the test block shell 12 needs to be discharged, by the displacement of the baffle 45, the opening of the test block shell 12 is closed. Through the operation of the first hydraulic cylinder 36, the first rack plate 35 can be driven to displace, driving the first gear 34 to rotate, driving the rotating column 33 to rotate, driving the mounting block 10 to rotate, driving the test block shell 12 on the mounting block 10 to rotate. When the opening of the test block shell 12 corresponds to the bearing plate 44, by the displacement of the baffle 45, the opening of the test block shell 12 is opened. At this time, the test block inside the test block shell 12 will fall onto the bearing plate 44. When the rotating column 33 rotates, through the cooperative work of the driving wheel 31 and the transmission belt 32, the adapter column 29 is driven to rotate, driving the cam 30 to rotate. At this time, the rotating cam 30 will intermittently press the sliding plate 24, driving the sliding plate 24 to displace, driving the sliding column 22 to displace. At this time, the displaced sliding column 22 will push the linkage column 25, driving the linkage column 25 to displace, driving the cushion plate 13 to displace. At this time, the displaced cushion plate 13 will push the test block inside the test block shell 12 to displace, preventing the test block inside the test block shell 12 from staying inside the test block shell 12 and improving the discharge efficiency of the test block. When all the test block shells 12 below the fifth slurry output pipe 9 are loaded with slurry, through the operation of the second electromagnetic three-way valve 7, the slurry can be transported into the fourth slurry output pipe 8. After that, the above operations can be repeated to continue preparing the test blocks, avoiding the situation where all the test block shells 12 below the fifth slurry output pipe 9 are loaded with slurry and the slurry has not solidified, making it impossible to carry out the test block preparation work.

[0034] An annular groove one is formed on the outer side of the base 11. A plurality of support blocks fixed to the inner wall of the mounting block 10 are slidably connected inside the annular groove one. Through the cooperative work of the annular groove one and the support blocks, the base 11 can be supported.

[0035] On one side of the base 11 away from the test block shell 12, a second annular groove 18 is provided. A connecting ring 19 is slidably connected inside the second annular groove 18. Inside the notch of the connecting ring 19, a plurality of stabilizing columns 20 fixed on the connecting ring 19 are slidably connected. One end of the stabilizing column 20 away from the connecting ring 19 is fixed on the inner wall of the mounting block 10. Through the cooperation of the second annular groove 18, the connecting ring 19 and the stabilizing column 20, the stability performance of the base 11 can be improved, and the base 11 can be prevented from shifting during rotation.

[0036] A connecting spring 23 is movably sleeved outside the sliding column 22 located inside the mounting frame 28. One end of the connecting spring 23 is fixed on the sliding plate 24, and the other end of the connecting spring 23 is fixed on the mounting block 10. Through the elasticity of the connecting spring 23, when the cam 30 separates from the sliding plate 24, the displaced sliding plate 24 can be pushed to reset.

[0037] A piston 41 is slidably connected inside the second chamber 38. The piston 41 is provided with a movable hole, and a water delivery pipe 39 is slidably inserted through the movable hole. One end of the water delivery pipe 39 extends into the first chamber 46. A plurality of spray heads 40 fixed on the inner wall of the top of the first chamber 46 are installed on the water delivery pipe 39 located inside the first chamber 46. One end of the rotating column 33 located inside the second chamber 38 is fixed with a driving plate one 42. One end of the driving plate one 42 away from the rotating column 33 is hinged with a driving plate two 43. One end of the driving plate two 43 away from the driving plate one 42 is hinged with a fixing block fixed on the piston 41. When the rotating column 33 rotates, the driving plate one 42 will be driven to rotate. At this time, the rotating driving plate one 42 will drive the driving plate two 43 to deflect, driving the piston 41 and the fixing block to perform reciprocating displacement. At this time, the reciprocating piston 41 will compress the water liquid inside the second chamber 38 into the water delivery pipe 39, and the water liquid inside the water delivery pipe 39 will be ejected through the spray heads 40. At this time, the water mist ejected by the spray heads 40 will increase the humidity inside the first chamber 46, preventing the test block inside the first chamber 46 from cracking due to low humidity, and curing the test block inside the first chamber 46.

[0038] A liquid injection valve is installed on the outer side of the housing 6, and the liquid injection valve is communicated with the second chamber 38. Through the liquid injection valve, a sufficient amount of water liquid can be injected into the second chamber 38.

[0039] The baffle 45 is provided with a grouting hole 37, and the grouting hole 37 corresponds to the test block shell 12. Through the grouting hole 37, the baffle 45 can be prevented from interfering with the injection of the slurry into the test block shell 12 by the slurry output pipe four 8 and the slurry output pipe five 9.

[0040] Embodiment 3:

[0041] Combined with Figure 7, on the basis of Embodiment 1, the further improvement of this embodiment lies in that: a first movable door 47 and a second movable door 48 are hinged to the outside of the housing 6. The first movable door 47 communicates with the second chamber 38, and the second movable door 48 communicates with the first chamber 46. A sealing ring is provided on the outside of the first movable door 47. By opening the first movable door 47 and the second movable door 48, it is convenient for construction personnel to repair and maintain the components inside the housing 6, and it is convenient for construction personnel to take out the test block inside the first chamber 46, so as to monitor the performance of the test block.

[0042] Linking blocks 17 are fixed below both ends of the baffle 45. A screw sleeve is embedded in the middle of the linking block 17. A lead screw is threadedly inserted into the screw sleeve. One end of the lead screw is drivingly connected to a motor. The motor is a forward and reverse stepping motor. A fixing block 16 fixed on the base 11 is fixed to the outside of the motor. By running the motor, the lead screw can be driven to rotate. Through the threaded cooperation of the lead screw and the screw sleeve, the linking block 17 can be driven to displace, driving the baffle 45 to displace.

[0043] Working principle: Connect the tail end of the slurry input pipe 1 to the slurry conveying equipment. Convey the slurry to the inside of the slurry output pipe 2 through the slurry input pipe 1. The slurry entering the inside of the slurry output pipe 2 is ejected through the grouting pipe 4. At this time, the slurry ejected through the grouting pipe 4 conducts grouting operation on the surrounding rock. When it is necessary to prepare a slurry test block, through the operation of the motor, drive the lead screw to rotate. Through the threaded fit of the lead screw and the nut sleeve, drive the linkage block 17 to displace, drive the baffle 45 to displace. When the baffle 45 opens the opening of the corresponding test block shell 12, through the operation of the first electromagnetic three-way valve 2, convey the slurry inside the slurry input pipe 1 to the inside of the slurry output pipe 3. Through the operation of the second electromagnetic three-way valve 7, convey the slurry to the inside of the slurry output pipe 5. Convey the slurry to the inside of the corresponding test block shell 12 through the slurry output pipe 5. When the test block shell 12 near the slurry output pipe 5 is filled with slurry, through the operation of the second hydraulic cylinder 15, drive the second rack plate 14 to displace, drive the driving column to rotate, drive the base 11 to rotate, drive the test block shell 12 on the base 11 to rotate. When the test block shell 12 without loaded slurry rotates below the slurry output pipe 5, sufficient slurry can be conveyed to the inside of the corresponding test block shell 12 through the slurry output pipe 5. After that, the above operations can be repeated until all the test block shells 12 are filled with slurry. When the slurry inside the test block shell 12 solidifies and it is necessary to discharge the test block inside the test block shell 12, through the displacement of the baffle 45, close the opening of the test block shell 12. Through the operation of the first hydraulic cylinder 36, drive the first rack plate 35 to displace, drive the first gear 34 to rotate, drive the rotating column 33 to rotate, drive the mounting block 10 to rotate, drive the test block shell 12 on the mounting block 10 to rotate. When the opening of the test block shell 12 corresponds to the bearing plate 44, through the displacement of the baffle 45, open the opening of the test block shell 12. At this time, the test block inside the test block shell will fall on the bearing plate 44. When the rotating column 33 rotates, through the cooperative work of the transmission wheel 31 and the transmission belt 32, drive the adapter column 29 to rotate, drive the cam 30 to rotate. At this time, the rotating cam 30 will intermittently press the slide plate 24, drive the slide plate 24 to displace, drive the sliding column 22 to displace. At this time, the displaced sliding column 22 will push the linkage column 25, drive the linkage column 25 to displace, drive the backing plate 13 to displace. At this time, the displaced backing plate 13 will push the test block inside the test block shell to displace, prevent the test block inside the test block shell from staying inside the test block shell, and improve the discharge efficiency of the test block. When all the test block shells 12 below the slurry output pipe 5 are filled with slurry, through the operation of the second electromagnetic three-way valve 7, convey the slurry to the inside of the slurry output pipe 4. After that, the above operations can be repeated to continue preparing the test blocks, avoiding the situation that when all the test block shells 12 below the slurry output pipe 5 are filled with slurry and the slurry has not solidified, the test block preparation work cannot be carried out. When the rotating column 33 rotates, it will drive the first driving plate 42 to rotate.At this time, the driving plate 1 42 that rotates will drive the driving plate 2 43 to deflect, driving the piston 41 and the fixed block to move reciprocally. At this time, the reciprocally moving piston 41 will compress the water liquid inside the chamber 2 38 into the water delivery pipe 39, and the water liquid inside the water delivery pipe 39 will be ejected through the nozzle 40. At this time, the water mist ejected by the nozzle 40 will increase the humidity inside the chamber 1 46, preventing the humidity of the test block inside the chamber 1 46 from being too low, which may cause the test block inside the chamber 1 46 to crack, and thus curing the test block inside the chamber 1 46.
