A wall drilling and grouting device for building construction

Abstract

This application relates to the technical field of building drilling and grouting equipment, and discloses a wall drilling and grouting device for building construction, including a mounting base. A second movable base is slidably disposed on one side of the top of the mounting base, and a grouting pipe is fixedly disposed on the top of the second movable base. A sealing sleeve is disposed on one side of the grouting pipe. This invention, through the cooperation of a sliding block with the air pressure adjustment of a contraction bladder and the corresponding spring, automatically completes the locking process when the sealing sleeve is pre-fitted, and removes the connection with the sealing sleeve after subsequent grouting. Simultaneously, the transmission mechanism drives a rotating ring to rotate the movable sleeve forward, increasing the sealing pressure during the insertion of the sealing sleeve into the grouting hole. This causes the flexible pad to fill the inner wall of the irregular grouting hole, improving the sealing effect. Combined with the sliding block's fixing and loosening of the sealing sleeve, this improves the efficiency of drilling and grouting operations and further enhances the reliability of the drilling and grouting equipment.

Description

Technical Field

[0001] This application relates to the field of building drilling and grouting equipment technology, and in particular to a wall drilling and grouting device for building construction. Background Technology

[0002] In repairing leaking walls, drilling holes must first be used to create grouting holes in the corresponding leaking areas. Then, grouting equipment is used to inject grout into these holes. Currently, the grouting equipment includes a grouting pipe connected to a liquid pump. Before grouting the wall, a corresponding tubular seal is inserted into the grouting hole using appropriate tools to seal the gap between the grouting pipe and the hole wall during the subsequent grouting process.

[0003] However, the traditional drilling and grouting process relies on manual operation. The diameter and depth of the holes drilled by the drilling equipment are prone to deviation. During the subsequent insertion of the sealing element, the specifications of the sealing element may not be compatible with the diameter of the grouting hole, which can easily lead to gaps. This can cause grout to flow out of the grouting hole if the rated pressure is not reached during the grouting process, affecting the quality of grouting and reducing the effectiveness of wall repair. Furthermore, the sealing and grouting processes are carried out separately, which involves more work and reduces the efficiency of wall repair, making it difficult to adapt to emergency repairs of leaking walls within the rated time. Summary of the Invention

[0004] This application proposes a wall drilling and grouting device for building construction, which has the advantages of improving sealing effect and repair efficiency, and solves the problems of poor sealing of grouting pipe and low efficiency of drilling and grouting operation that are easy to occur when manually operating drilling and grouting.

[0005] To achieve the above objectives, this application adopts the following technical solution: a wall drilling and grouting device for building construction, comprising a mounting base, a second movable base slidably disposed on one side of the top of the mounting base, a grouting pipe fixedly disposed on the top of the second movable base, a sealing sleeve disposed on one side of the grouting pipe, a flexible pad movably disposed on one side of the sealing sleeve, a movable ring movably disposed on one side of the sealing sleeve, an inner tube disposed inside the grouting pipe, a second partition plate that allows grout to pass through fixedly disposed on one side of the inner tube, and a sliding block slidably disposed on one side of the inner tube;

[0006] It also includes an adjustment mechanism, which can drive the moving ring to approach the corresponding distance of the sealing sleeve according to the moving position of the second moving seat. In conjunction with the sealing sleeve, the two end faces of the flexible pad are squeezed. After the second moving seat moves forward to the grouting position, the adjustment mechanism can drive the sliding block to retract into the inner tube, and can also drive the sliding block to revert and extend out of the inner tube during the resetting process of the second moving seat.

[0007] Furthermore, the adjustment mechanism includes a first partition plate, which is fixedly connected to the grouting pipe and the inner pipe. The first partition plate is provided with a through hole that is controlled to open and close by a control valve. A movable ring is movably fitted on one side of the sealing sleeve, and a movable sleeve is threaded onto the outer side of the sealing sleeve. A rotating ring is slidably fitted onto the outer side of the movable sleeve. A movable block that can be connected to the sealing sleeve is provided on one side of the wall of the grouting pipe. A through hole for grout to pass through is provided on the second partition plate. A first movable seat is slidably provided on one side of the top of the mounting base, and a drilling mechanism is fixedly provided on the top of the first movable seat.

[0008] Furthermore, the outer wall of the movable sleeve is a regular polygon, the adjustment mechanism also includes a contraction bladder, the side of the sliding block away from the axis of the inner tube is an inclined plane, the side of the sliding block located inside the inner tube is slidably engaged with a connecting rod, the connecting rod is T-shaped, one end of the connecting rod is fixedly connected to the contraction bladder, the end of the connecting rod near the axis of the inner tube is slidably engaged with a fixing block, the fixing block is fixedly connected to the inner tube, and a spring is provided between the fixing block and the sliding block.

[0009] Furthermore, the adjustment mechanism also includes an air cylinder, which is fixedly connected to the second movable seat. An air vent is provided on one side of the air cylinder, and a sliding plug is slidably disposed on the inner side of the air cylinder. An air inlet pipe is fixedly disposed on the other side of the air cylinder, and an air outlet pipe is fixedly disposed on one side of the air cylinder. A one-way valve is fixedly disposed on the air inlet pipe. A connecting pipe is fixedly connected to one side of the inner tube, and the air outlet pipe is connected to the connecting pipe via a pipe. A pressure relief pipe is fixedly connected to one side of the inner tube, and a solenoid valve is fixedly disposed on the pressure relief pipe. The orifice of the inner tube communicates with the cavity of the contraction bladder.

[0010] Furthermore, a sealing block for sealing the corresponding through hole is slidably sleeved on one side of the second partition, and a spring is fixedly connected between the sealing block and the end of the sealing sleeve.

[0011] Furthermore, the adjustment mechanism also includes a guide rod, which is fixedly connected to the air cylinder. An adjustment rod is slidably sleeved on the outer side of the guide rod. The adjustment rod has a spiral adjustment groove on its body. A transmission mechanism is provided on one side of the second movable seat. The transmission mechanism is connected to an adjustment block. A contact switch is fixedly provided at the end of the guide rod near the air cylinder. The contact switch is electrically connected to the solenoid valve of the pressure relief pipe. A spring is movably provided on the side of the sliding plug near the air inlet pipe. A moving rod is fixedly connected to one side of the sliding plug.

[0012] Furthermore, the transmission mechanism includes an external gear and a ratchet gear, both of which are rotatably connected to the second movable seat. A stop pawl is rotatably provided on the inner side of the external gear, and a spring is fixedly connected between the stop pawl and the external gear. The stop pawl, in conjunction with the corresponding spring, enables the ratchet gear to drive the external gear to rotate in one direction. The ratchet gear is fixedly connected to the adjusting block, and the adjusting block is slidably connected to the adjusting groove.

[0013] Furthermore, a connecting gear is rotatably provided on one side of the grouting pipe, a transmission ring is fixedly connected to one side of the connecting gear, a transmission key is fixedly provided on the inner side of the transmission ring, the transmission ring and the rotating ring are slidably sleeved together, a connecting groove is provided on one side of the rotating ring, and the transmission key is slidably connected to the connecting groove.

[0014] Furthermore, a spring is provided between the rotating ring and the connecting gear, and a spring is provided between the movable block and the grouting pipe for pushing the movable block closer to the sealing sleeve. The connecting gear and the external gear mesh with each other.

[0015] The beneficial effects of this invention are as follows:

[0016] This application provides a wall drilling and grouting device for building construction. As the second movable seat approaches the wall, the adjusting rod rotates, which in turn drives the connecting gear to rotate in one direction. The connecting gear drives the movable sleeve to rotate towards the end of the sealing sleeve. As the sealing sleeve is inserted into the grouting hole, it squeezes the flexible pad to seal the gap between the grouting hole and the sealing sleeve. This allows the drilling and grouting device to seal even when the inner wall of the drill hole is uneven, and improves the sealing effect.

[0017] This application provides a wall drilling and grouting device for building construction. A sliding block extends and retracts in conjunction with a corresponding spring, a contraction bladder, and a connecting rod. When the sealing sleeve is pre-fitted onto the grouting pipe, the sliding block remains extended. As the second partition passes the sliding block, it pushes the inclined surface, causing the slider to contract. The subsequent extension of the sliding block restricts the axial movement of the sealing sleeve. After the sealing sleeve is inserted, the contraction bladder inflates, causing the sliding block to extend. This improves the overall drilling and grouting efficiency while allowing the sealing sleeve to remain inside the grouting hole, acting as a seal after grouting. Combined with the transmission mechanism, this completes the sealing process during grouting, further enhancing the reliability of the drilling and grouting equipment. Attached Figure Description

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1, as Figures 1-7 and Figure 9 A wall drilling and grouting device for building construction includes a mounting base 1, which supports a drilling and grouting component. The mounting base 1 is installed on a horizontal linear guide rail module of a supporting lifting platform, allowing the mounting base 1 to adjust its height and horizontal position. For example, the supporting lifting platform is configured as a working trolley, and a lifting seat is provided on the working trolley. The lifting seat is driven to rise and fall by an electric push rod. When the working trolley moves the mounting base 1 to the working position, the horizontal linear guide rail module moves the mounting base 1 horizontally to switch the corresponding positions of the drilling component and the grouting component with the wall. For example, the horizontal linear guide rail module is configured as a lead screw driven by a motor and a linear guide rail. The lead screw drives the mounting base 1 to move along the linear guide rail.

[0032] A first movable seat 2 is slidably mounted on one side of the top of mounting base 1. A drilling mechanism 3 is fixedly mounted on the top of the first movable seat 2. The first movable seat 2 is driven by an electric push rod and can move horizontally relative to mounting base 1 to adjust the distance between the drilling mechanism 3 and the wall. The drilling mechanism 3 is used to drill holes in the wall. For example, the drilling mechanism 3 can be configured as a drill barrel driven by a motor. A second movable seat 4 is slidably mounted on one side of the top of mounting base 1. The second movable seat 4 is driven by an electric push rod and can move horizontally relative to mounting base 1. A grouting pipe 5 is fixedly mounted on the top of the second movable seat 4. The grouting pipe 5 is connected to a grouting pump through a pipeline. (See reference...) Figure 4 A first partition plate 13 is fixedly sleeved on one side of the grouting pipe 5. The first partition plate 13 is provided with a through hole for grout to pass through. A control valve is provided on the through hole to control the opening and closing of the through hole.

[0033] A sealing sleeve 6 is provided on one side of the grouting pipe 5. A flexible gasket 7 is movably fitted on one side of the sealing sleeve 6. The sealing sleeve 6 is used to seal the gap between the grouting pipe 5 and the grouting hole by cooperating with the flexible gasket 7. A movable ring 16 is movably fitted on one side of the sealing sleeve 6. The movable ring 16 is located on one side of the flexible gasket 7 and is used to clamp the two ends of the flexible gasket 7 by cooperating with one end face of the sealing sleeve 6. A movable sleeve 12 is threaded on the outer side of the sealing sleeve 6. The movable sleeve 12 can be screwed in towards the side closer to the flexible gasket 7 by rotation. (See reference) Figure 6The outer wall of the movable sleeve 12 is a regular polygon. A rotating ring 9 is slidably sleeved on the outer side of the movable sleeve 12. The inner wall shape of the rotating ring 9 is adapted to the outer wall shape of the movable sleeve 12. While the rotating ring 9 drives the movable sleeve 12 to rotate, the movable sleeve 12 can move axially relative to the rotating ring 9.

[0034] A movable block 19 is provided on one side of the grouting pipe 5. (See reference) Figure 7 The movable block 19 can be inserted into the end of the sealing sleeve 6 and slidably sleeved with the sealing sleeve 6. The movable block 19 is used to restrict the rotation of the sealing sleeve 6 relative to the grouting pipe 5. The inner tube 14 is fixedly sleeved at the middle position of the first partition 13. The second partition 15 is fixedly sleeved on one side inside the sealing sleeve 6. The second partition 15 has through holes for grout to pass through. The number of through holes corresponding to the second partition 15 is set to several. See reference. Figure 5 A contraction bladder 21 is provided on one side of the inner tube 14. The contraction bladder 21 has a tendency to contract. A sliding block 22 is slidably sleeved on one side of the inner tube 14. The number of sliding blocks 22 is at least one. The sliding blocks 22 are arranged at even intervals on the outer side of the inner tube 14. The side of the sliding block 22 away from the axis of the inner tube 14 is inclined. The sliding block 22 is used to restrict the axial movement of the second partition 15 away from the grouting pipe 5, thereby restricting the axial movement of the sealing sleeve 6 relative to the corresponding direction of the grouting pipe 5.

[0035] A connecting rod 23 is slidably engaged with one side of the sliding block 22 inside the inner tube 14. The connecting rod 23 is T-shaped and can move radially relative to the sliding block 22 in the inner tube 14 without disengaging from the sliding block 22. One end of the connecting rod 23 is fixedly connected to the contraction bladder 21. A fixing block 24 is slidably sleeved at the end of the connecting rod 23 near the axis of the inner tube 14. The fixing block 24 is fixedly connected to the inner tube 14. A spring is provided between the fixing block 24 and the sliding block 22. The spring is used to push the sliding block 22 out of the inner tube 14. The contraction bladder 21 can overcome the spring force corresponding to the sliding block 22 and drive the sliding block 22 to retract into the inner tube 14. The second partition 15 is movably sleeved with the inner tube 14.

[0036] When drilling and grouting the wall, the movable sleeve 12 is in a threaded engagement with the sealing sleeve 6, and the movable ring 16 is in a clamping state with the sealing sleeve 6, holding the flexible pad 7 flat. The sealing sleeve 6 is pre-fitted onto the grouting pipe 5, so that the movable block 19 fits into the sealing sleeve 6, and the sealing sleeve 6 and the end face of the grouting pipe 5 form a seal. At this time, the rotating ring 9 and the movable sleeve 12 are fitted together. During the fitting process of the sealing sleeve 6, the sealing sleeve 6 drives the second partition 15 to fit onto the outside of the inner pipe 14. When the second partition 15 contacts the inclined surface of the sliding block 22, it drives the sliding block 22 to overcome the corresponding spring force and retract towards the inner pipe 14 until the sealing sleeve 6 is fitted into place. At this time, the second partition 15 disengages from the sliding block 22, and the corresponding spring pushes the sliding block 22 to extend. The sliding block 22 restricts the axial movement of the second partition 15 relative to the grouting pipe 5 to complete the pre-fitting of the sealing sleeve 6, thereby simplifying the installation steps of the sealing element, improving the overall grouting efficiency, and saving manpower.

[0037] Adjust the mounting base 1 to the corresponding position, drive the drilling mechanism 3 to approach the wall, and the drilling mechanism 3 drills grouting holes in the wall. After drilling is completed, drive the drilling mechanism 3 to disengage from the wall, adjust the horizontal position of the mounting base 1, and the mounting base 1 drives the grouting pipe 5 to move and switch the corresponding position of the grouting pipe 5 so that the axis of the grouting pipe 5 is collinear with the axis of the grouting hole. The second moving base 4 moves closer to the wall via the electric push rod, and the second moving base 4 drives the grouting pipe 5 closer to the wall. The transmission drives the end of the sealing sleeve 6 to be inserted into the grouting hole to the rated length, and rotate the rotating ring 9. The rotating ring 9 rotates with the belt... The movable sleeve 12 rotates and rotates forward relative to the sealing sleeve 6. When it is in the correct position, the movable sleeve 12 disengages from the rotating ring 9. The rotation of the movable sleeve 12 drives the movable ring 16 to approach the end of the sealing sleeve 6. The movable ring 16 cooperates with the sealing sleeve 6 to squeeze the flexible pad 7, causing the middle part of the flexible pad 7 to arch up, thereby increasing the sealing pressure of the flexible pad 7 and expanding the sealing diameter of the flexible pad 7. This allows the flexible pad 7 to form a seal between the irregular grouting hole and the grouting pipe 5 on the inner wall, simplifying the sealing steps while improving the sealing effect and increasing the reliability of the drilling grouting device.

[0038] A sealing block 20 for sealing the corresponding through hole is slidably sleeved on one side of the second partition 15. The position of the sealing block 20 corresponds to the through hole of the second partition 15. A spring is fixedly connected between the sealing block 20 and the end of the sealing sleeve 6. The spring corresponding to the sealing block 20 is used to push the sealing block 20 closer to the second partition 15 to block the corresponding through hole. After sealing, the control valve corresponding to the first partition 13 is opened, and the slurry is drawn by the pump and passed through the grouting pipe 5 through the corresponding through hole of the first partition 13. The grout overcomes the elastic force of the spring corresponding to the sealing block 20 and pushes the sealing block 20 away from the corresponding through hole. The grout enters the grouting hole through the gap between the sealing block 20 and the sealing sleeve 6 until the pumped grout pressure reaches the rated value and the grout flows out through the water leakage gap of the wall, completing the grouting. The pumping of grout stops, the control valve is closed, and the sealing block 20 is pushed by the corresponding spring to seal the through hole of the second partition 15, preventing the grout from flowing back out when the grouting pipe 5 is withdrawn from the grouting hole.

[0039] An air cylinder 30 is fixedly installed on one side of the second movable base 4. (See reference) Figure 9 A vent 33 is provided on one side of the air cylinder 30, and a sliding plug 31 is slidably disposed on the inner side of the air cylinder 30. An air inlet pipe 34 is fixedly disposed on the other side of the air cylinder 30, and an air outlet pipe 35 is fixedly disposed on one side of the air cylinder 30. A one-way valve for gas to enter the air cylinder 30 through the air inlet pipe 34 is fixedly disposed on the air inlet pipe 34. (See reference) Figure 4 A connecting pipe 37 is fixedly connected to one side of the inner tube 14. An air outlet pipe 35 is connected to the connecting pipe 37 through a pipe. A pressure relief pipe 36 is fixedly connected to one side of the inner tube 14. A solenoid valve is fixedly installed on the pressure relief pipe 36. The pipe hole of the inner tube 14 is connected to the cavity of the contraction bag 21. The air inlet pipe 34 and the air outlet pipe 35 are located on one side of the sliding plug 31, and the vent 33 is located on the other side of the sliding plug 31.

[0040] After grouting is completed, the solenoid valve opens, the contraction bladder 21 contracts, the contraction bladder 21 drives the connecting rod 23 to move, the connecting rod 23 drives the sliding block 22 to move and contract into the inner tube 14, the limit of the second partition 15 is removed, the second moving seat 4 moves and drives the grouting pipe 5 to exit the grouting hole, and the grouting is completed. The sliding plug 31 is controlled by the drive component to move closer to the air outlet pipe 35, and the rated amount of gas is filled into the contraction bladder 21. The contraction bladder 21 expands, and the connecting rod 23 moves to remove the pull on the sliding block 22. The spring corresponding to the sliding block 22 drives the sliding block 22 to reset.

[0041] Example 2, as Figures 1-10Based on Embodiment 1, a guide rod 28 is fixedly connected to one end of the air cylinder 30 near its midpoint. An adjusting rod 25 is slidably sleeved on the outer side of the guide rod 28. The adjusting rod 25 has a spiral adjusting groove 26 on its body. A transmission mechanism 8 is provided on one side of the second movable seat 4. The transmission mechanism 8 includes an external gear 801 and a ratchet 802. Both the ratchet 802 and the external gear 801 are rotatably connected to the second movable seat 4. (See reference...) Figure 8 The inner side of the external gear 801 is provided with a stop pawl 803, and a spring is fixedly connected between the stop pawl 803 and the external gear 801. The stop pawl 803, in conjunction with the corresponding spring, enables the ratchet 802 to drive the external gear 801 to rotate in one direction. An adjusting block 27 is fixedly connected to the inner side of the ratchet 802, and the adjusting block 27 is slidably connected to the adjusting groove 26. A contact switch 29 is fixedly provided at the end of the guide rod 28 near the air cylinder 30. The contact switch 29 is electrically connected to the solenoid valve of the pressure relief pipe 36. A spring is movably provided on the side of the sliding plug 31 near the air inlet pipe 34.

[0042] A movable rod 32 is fixedly connected to one side of the sliding plug 31. The movable rod 32 extends out of the air cylinder 30. The number of movable rods 32 is set to at least one. The movable rod 32 is fixedly connected to the adjusting rod 25. A connecting gear 11 is rotatably provided on one side of the grouting pipe 5. A transmission ring 10 is fixedly connected to one side of the connecting gear 11. A transmission key 18 is fixedly provided on the inner side of the transmission ring 10. The transmission ring 10 is slidably sleeved with the rotating ring 9. A connecting groove 17 is opened on one side of the rotating ring 9. The transmission key 18 is slidably connected with the connecting groove 17. A spring is provided between the rotating ring 9 and the connecting gear 11. The spring corresponding to the rotating ring 9 is used to push the rotating ring 9 to maintain its sleeve with the movable sleeve 12. The movable block 19 is slidably connected to the grouting pipe 5. The movable block 19 can slide axially without disengaging from the grouting pipe 5. A spring is provided between the movable block 19 and the grouting pipe 5 to push the movable block 19 closer to the sealing sleeve 6. The connecting gear 11 and the external gear 801 mesh with each other.

[0043] As the second moving seat 4 moves the grouting pipe 5 closer to the wall, the sealing sleeve 6 is inserted into the grouting hole. At this time, the end of the adjusting rod 25 contacts the wall. The second moving seat 4 continues to move, causing the guide rod 28 and ratchet 802 to move relative to the adjusting rod 25. The inner wall of the adjusting groove 26 corresponding to the adjusting rod 25 abuts against the adjusting rod 25, causing the adjusting rod 25 to rotate relative to the second moving seat 4. The rotation of the adjusting rod 25 drives the external gear 801 to rotate in one direction. The movement of the grouting pipe 5 drives the connecting gear 11 to move synchronously. The rotation of the external gear 801 drives the connecting gear 11 to rotate. The connecting gear 11 drives the transmission ring 10 to rotate. The transmission ring 10 drives the rotating ring 9 to rotate through the transmission key 18, thereby rotating the moving sleeve 12. During the process of the sealing sleeve 6 being inserted into the grouting hole, the flexible pad 7 is pushed up and arched.

[0044] When the sealing sleeve 6 is inserted, the adjusting rod 25 contacts and activates the contact switch 29. The contact switch 29 opens the corresponding solenoid valve, causing the contraction bladder 21 to depressurize and contract. This drives the sliding block 22 to contract, removing the limit on the second partition 15, which facilitates the subsequent withdrawal of the grouting pipe 5. When the second moving seat 4 drives the grouting pipe 5 to withdraw from the grouting hole, the spring corresponding to the sliding plug 31 drives the sliding plug 31 to slide and reset, and presses air into the contraction bladder 21 through the air outlet pipe 35, the connecting pipe 37, and the inner pipe 14. As the sliding block 22 moves, it extends through the second partition 15. Thus, during the grouting process, the extension and retraction control of the sliding block 22 and the end compression of the flexible pad 7 are completed, further improving the efficiency of the grouting operation.

[0045] Simultaneously, the rotating ring 9 can move axially relative to the connecting gear 11, and the movable block 19 can move axially relative to the grouting pipe 5. When secondary grouting is required, the grouting pipe 5 performs grouting on the sealing sleeve 6 left during the first grouting of the sealing hole. When the movable sleeve 12 loosens, the movable sleeve 12 retracts a certain distance, and the grouting pipe 5 drives the rotating ring 9 to move. The rotating ring 9 rotates at the same time, so that the rotating ring 9 can abut against the movable sleeve 12 and rotate, and the movable block 19 abuts against the sealing sleeve 6 and rotates, so that the rotating ring 9 re-engages with the retracted movable sleeve 12. The transmission drives the movable ring 16 to squeeze the flexible pad 7 again, ensuring sealing performance and improving the applicability of the drilling grouting device while further improving its reliability.
