Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to a mobile grouting device for water conservancy and hydropower construction. Background Art

[0002] During the construction of water conservancy and hydropower projects, grouting technology is often used to pump the slurry into the cracks of the foundation rock and soil, so as to improve the integrity and impermeability of the rock and soil, and then improve the foundation conditions to ensure the safe operation of hydraulic structures. Generally, it is necessary to drill holes on the ground first, and then inject the slurry for grouting into the drilled holes, so that the slurry flows along the drilled holes into the cracks below the drilled holes.

[0003] Ordinary equipment can only achieve the release of the slurry. In practice, small cracks will occur on the drilling wall. The openings of these cracks are narrow and the depth is long. When the actual slurry flows into such gaps, an air cavity will be formed due to the blockage of the slurry. This situation is more likely to occur when the crack extends upward. Due to the blocking of the slurry by the air pressure in the air cavity, the slurry cannot flow further into the deep part of the gap, resulting in incomplete grouting and reducing the quality of grouting construction.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During use, the bracket is erected above the drill hole to be grouted, and the gap negative pressure structure is suspended above the drill hole. Then, the rectangular sleeve is moved by controlling the angle adjustment moving part and the vertical release part through the control panel, so that the rectangular sleeve drives the protective shell to move towards the gap on the drill hole wall, and the gap clamping and leakage prevention part is clamped into the gap wall. During this period, due to the provision of the anti-rotation bracket, when the protective shell has a tendency to rotate, it is convenient to limit the rotation of the protective shell by the way that the anti-rotation bracket abuts against the drill hole wall and the gap clamping and leakage prevention part clamps the gap wall. Then, the elastic extension part extends into the gap, and the vertical release part is disengaged from the rectangular sleeve. After the gap negative pressure structure is installed on all the gaps where the position adjustment and release structure needs to be installed, the central grouting structure performs grouting operations on the drill hole, so that the slurry falls into the drill hole and flows. And due to the power supply of the independent power source to the negative pressure suction part, the negative pressure suction part performs negative pressure extraction operations through the elastic extension part, so that a negative pressure is formed in the gap. At this time, the slurry actively flows along the gap to promote further filling of the slurry in the gap and improve the grouting effect. When it is necessary to take out the gap negative pressure structure, while the control panel controls the electric telescopic frame to extend through the wireless communication module, the gap clamping and leakage prevention part actively contracts, so as to facilitate the extended electric telescopic frame to push against the drill hole wall, so that the protective shell is away from the gap, so that the operator can pull out the gap negative pressure structure from the drill hole by lifting the pull rope. Through the mutual cooperation among the central grouting structure, the position adjustment and release structure, and the gap negative pressure structure, the present invention facilitates the smooth flow of the slurry into the gap, thereby improving the quality of the grouting construction.

Detailed implementation manners

[0034] The technical solution of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0035] Example 1. Refer to Figures 1 to 15 As shown, a grouting device for mobile water conservancy and hydropower construction includes a support 1. There is an axially protruding structure on the support 1. The support 1 is fixedly connected with a control panel, and further includes:

[0036] A central grouting structure 2 connected to the support 1. The central grouting structure 2 is connected to an external slurry supply device;

[0037] A position adjustment and release structure 3 connected to the support 1. The position adjustment and release structure 3 includes an angle adjustment and moving part 4 connected to the support 1, and the angle adjustment and moving part 4 is connected with a vertical release part 5;

[0038] The slit negative pressure structure 6 connected to the vertical release part 5, the slit negative pressure structure 6 includes a rectangular sleeve 7 movably connected to the vertical release part 5, the rectangular sleeve 7 is fixedly connected with a protective shell 8, the protective shell 8 is connected with a negative pressure suction part 9, the negative pressure suction part 9 is connected with an elastic extension part 10, a wireless communication module 11 is fixedly installed in the protective shell 8, an independent power supply 12 is fixedly installed in the protective shell 8, the protective shell 8 is connected with a slit leakage prevention part 13, the slit leakage prevention part 13 is connected with the elastic extension part 10, the protective shell 8 is connected with a pull rope 14, a turnover prevention bracket 83 is fixedly connected to the outer wall of the protective shell 8, and multiple groups of electric telescopic frames 84 are fixedly installed in the protective shell 8. Through the mutual cooperation of the position adjustment operation of the vertical release part 5 by the angle adjustment moving part 4 and the height adjustment operation of the vertical release part 5 on the slit negative pressure structure 6, the relative position between the slit negative pressure structure 6 and the slit of the drilling wall is adjusted.

[0039] During use, the support 1 is erected above the drilling hole to be grouted, and the slit negative pressure structure 6 is suspended above the drilling hole. Then, the rectangular sleeve 7 is moved by controlling the angle adjustment moving part 4 and the vertical release part 5 through the control panel, so that the rectangular sleeve 7 drives the protective shell 8 to move towards the slit on the drilling wall. The slit leakage prevention part 13 is clamped into the slit wall. During this period, due to the provision of the turnover prevention bracket 83, when the protective shell 8 has a tendency to rotate, the rotation of the protective shell 8 is restricted by the way that the turnover prevention bracket 83 abuts against the drilling wall and the slit leakage prevention part 13 clamps the slit wall. Then, the elastic extension part 10 extends into the slit, and the vertical release part 5 is separated from the rectangular sleeve 7. After the slit negative pressure structure 6 is installed on all the slits where the position adjustment and release structure 3 needs to be installed, the central grouting structure 2 performs grouting operation on the drilling hole, so that the slurry falls into the drilling hole and flows. And due to the power supply of the independent power supply 12 to the negative pressure suction part 9, the negative pressure suction part 9 performs negative pressure extraction operation through the elastic extension part 10, so that a negative pressure is formed in the slit. At this time, the slurry actively flows along the slit to promote the further filling of the slurry in the slit and improve the grouting effect. When the slit negative pressure structure 6 needs to be taken out, while the control panel controls the electric telescopic frame 84 to extend through the wireless communication module 11, the slit leakage prevention part 13 actively contracts, so that the extended electric telescopic frame 84 pushes against the drilling wall, making the protective shell 8 away from the slit, so that the operator can pull out the slit negative pressure structure 6 from the drilling hole by lifting the pull rope 14. Through the mutual cooperation among the central grouting structure 2, the position adjustment and release structure 3, and the slit negative pressure structure 6, the present invention facilitates the smooth flow of the slurry into the slit, thereby improving the quality of grouting construction.

[0040] In a case of this embodiment, the central grouting structure 2 includes a double-output-shaft motor 15 fixedly connected to the bracket 1. The output end of the double-output-shaft motor 15 is fixedly connected to a swing arm 16. The swing arm 16 is fixedly connected to a grout outlet head 17. An internal thread is provided in the grout outlet head 17, and the internal thread of the grout outlet head 17 is used to connect to the pipe body for supplying materials. The double-output-shaft motor 15 drives the swing arm 16 to rotate. The rotating swing arm 16 drives the grout outlet of the grout outlet head 17 to face the drilling hole, so that the grout outlet head 17 can put the grout into the drilling hole. And when the angle-adjusting moving part 4 and the vertical-lowering releasing part 5 need to be used, the double-output-shaft motor 15 drives the swing arm 16 to rotate, so that the grout outlet head 17 moves away from the drilling hole, providing space for the movement of the vertical-lowering releasing part 5.

[0041] In a case of this embodiment, the angle-adjusting moving part 4 includes a limit ring 18 fixedly connected to the bracket 1. An annular limit groove 19 is formed in the limit ring 18. A through-channel frame 20 is rotatably connected to the annular limit groove 19. A through hole for accommodating the grout outlet head 17 is formed in the through-channel frame 20. The through-channel frame 20 is fixedly connected to a gear ring 21. The bracket 1 is fixedly connected to a first motor 22. The output shaft of the first motor 22 is fixedly connected to a gear 82 that meshes with the gear ring 21. The through-channel frame 20 is fixedly connected to a track plate 23. A plurality of dovetail grooves are formed in the track plate 23. The track plate 23 is fixedly connected to a first active telescopic rod 24. The first active telescopic rod 24 is fixedly connected to a parallel linkage 25 that is slidably connected to the dovetail groove. The parallel linkage 25 is connected to the vertical-lowering releasing part 5. The first motor 22 drives the gear 82 to rotate. The rotating gear 82 drives the gear ring 21 to rotate. The rotating gear ring 21 drives the through-channel frame 20 to rotate along the annular limit groove 19, and the through-channel frame 20 drives the track plate 23 to rotate. The first active telescopic rod 24 adjusts the position of the vertical-lowering releasing part 5 by driving the parallel linkage 25 to slide along the dovetail groove.

[0042] In a case of this embodiment, the vertical release portion 5 includes two sets of first active telescopic frames 26 symmetrically arranged. The first active telescopic frames 26 are fixedly connected to the parallel frame 25. The mobile end of the first active telescopic frame 26 is fixedly connected to a first wheel frame 27. Two sets of auxiliary wheels 28 are rotatably installed on the first wheel frame 27. A driving wheel 29 is arranged between the two sets of auxiliary wheels 28. The first wheel frame 27 is fixedly connected to a second motor 30. The output shaft of the second motor 30 is coaxially and fixedly connected to the driving wheel 29. The parallel frame 25 is fixedly connected to two sets of second active telescopic frames 31 symmetrically arranged. The mobile end of the second active telescopic frame 31 is fixedly connected to a second wheel frame 32. The second wheel frame 32 is rotatably connected to multiple sets of first abutting wheels 33. The second wheel frame 32 is rotatably connected to multiple sets of second abutting wheels 34. The first abutting wheels 33, the second abutting wheels 34, the driving wheel 29, and the auxiliary wheels 28 are jointly connected to a splicing and hoisting assembly 35. The splicing and hoisting assembly 35 includes multiple rectangular splicing strips 36 arranged in the vertical direction. The first abutting wheels 33, the second abutting wheels 34, and the auxiliary wheels 28 all provide limit guidance for the rectangular splicing strips 36 by abutting against the rectangular splicing strips 36. The rotating driving wheel 29 moves the rectangular splicing strips 36 by frictionally contacting the rectangular splicing strips 36. One end of the rectangular splicing strip 36 is provided with a threaded hole 37, and the other end of the rectangular splicing strip 36 is fixedly installed with a threaded shaft 38. The threaded shaft 38 arranged at the bottom of the splicing and hoisting assembly 35 is threadedly connected to a double-head frame 39. The double-head frame 39 is movably connected to a set of rectangular splicing strips 36. The double-head frame 39 is fixedly connected to two sets of third active telescopic frames 40. The mobile end of the third active telescopic frame 40 is movably connected to the rectangular sleeve 7. The threaded hole 37 on one set of the splicing and hoisting assembly 35 is threadedly connected to the threaded shaft 38 on the adjacent other splicing and hoisting assembly 35. With the threaded connection of the threaded hole 37 and the threaded shaft 38, the ends of the two rectangular splicing strips 36 abut against each other. Under the pressure between the two rectangular splicing strips 36, the maximum friction force between the two rectangular splicing strips 36 is increased to prevent the two rectangular splicing strips 36 from freely rotating relative to each other. By threadedly connecting the threaded hole 37 and the threaded shaft 38, the two rectangular splicing strips 36 are docked, thereby extending the length of the splicing and hoisting assembly 35. When the second motor 30 drives the driving wheel 29 to rotate and the driving wheel 29 abuts against the rectangular splicing strips 36, the splicing and hoisting assembly 35 moves. And since the third active telescopic frame 40 extends into the rectangular sleeve 7, the splicing and hoisting assembly 35 drives the rectangular sleeve 7 to move together, thereby adjusting the position of the protective shell 8. By actively contracting the first active telescopic frame 26 and the second active telescopic frame 31, the first wheel frames 27 move away from each other, and the second wheel frames 32 move away from each other, thereby providing space for disassembling the rectangular splicing strips 36.

[0043] In a case of this embodiment, the negative pressure suction part 9 includes a negative pressure box 41 fixedly connected to the protective shell 8. A partition plate 42 is slidably installed in the negative pressure box 41. The partition plate 42 divides the inner cavity of the negative pressure box 41 into a water cavity 43 and a negative pressure cavity 44. The water cavity 43 is filled with water. The negative pressure box 41 is threadedly connected with a sealing cover. As the sealing cover is opened, the negative pressure cavity 44 is connected to the external environment to facilitate the cleaning operation of the negative pressure cavity 44. The negative pressure cavity 44 is connected to a control valve 46 through a first pipe 45. The control valve 46 is connected to the elastic extension part 10. The control valve 46 is fixedly installed in the protective shell 8. A water pump 47 is fixedly installed in the water cavity 43. The water pump 47 is fixedly connected to a water bag 49 through a second pipe 48. The water bag 49 has elastic stretchability. A reflux valve 85 is fixedly installed on the second pipe 48. The water outlet end of the reflux valve 85 extends into the water cavity 43. The water bag 49 is arranged in the protective shell 8. When the water pump 47 pumps the water in the water cavity 43, through the diversion of the second pipe 48, the water flow is injected into the water bag 49, causing the volume of the water bag 49 to expand. At this time, due to the expansion of the volume of the water bag 49, the air pressure in the protective shell 8 increases accordingly. Also, due to the drop of the water level in the water cavity 43, the partition plate 42 slides down, and the volume of the negative pressure cavity 44 increases, so that a negative pressure is formed in the negative pressure cavity 44. Then, the negative pressure cavity 44 sucks air through the first pipe 45. At this time, the control valve 46 is opened, and the elastic extension part 10 is communicated with the first pipe 45. The negative pressure suction part 9 performs a negative pressure extraction operation on the elastic extension part 10. When the reflux valve 85 is opened, the water bag 49 contracts, and the water in the water bag 49 flows back into the water cavity 43 along the second pipe 48.

The notch provides space for the friction wheel 53 to contact the protective sleeve 51. A guide hose 54 is fixedly connected to the inner wall of the protective sleeve 51. The material hardness of the protective sleeve 51 is greater than that of the guide hose 54.

The two sets of linkage frames 72 are jointly slidably connected to a double-groove frame 73. The double-groove frame 73 is slidably installed in the columnar shell 61.The third motor 52 drives the friction wheel 53 to rotate, so that the friction wheel 53 drives the protective sleeve 51 to move. While the protective sleeve 51 moves along the elbow pipe 50, the protective sleeve 51 drives the material guiding hose 54 to move. Since the first connector 56 connects the second connector 57 and the protective sleeve 51, at this time, as the protective sleeve 51 moves into the gap, the first connector 56 drives the outer housing 58 to move into the gap through the second connector 57. Since the outer housing 58 is fixedly connected with the spherical shell 59, the spherical shell 59 slides on each surface of the gap. During this period, the lighting lamp 62 performs lighting operations and the camera 65 performs imaging operations. With the opening of the control valve 46 and the progress of the negative pressure extraction operation, a negative pressure is formed inside the gap between the central housing 60 and the outer housing 58. At this time, under the action of air pressure, the plug body 71 moves into the outer housing 58. And since the plug body 71 drives the moving frame 69 to move, the linkage gear 67 rolls on the second rack 68. During the movement, the rolling linkage gear 67 drives the first rack 66 to move, and the moving distance of the first rack 66 is greater than the linear moving distance of the linkage gear 67. At this time, the pulling frame 64 pulls the camera 65 to move into the column housing 61. And as the pulling frame 64 separates from the arc-shaped baffle 63, under the push of the return spring, the arc-shaped baffles 63 approach each other until the two symmetrically arranged arc-shaped baffles 63 abut against each other, so as to protect the camera 65 in the sealed space inside the column housing 61. And since the arc-shaped baffle 63 drives the linkage frame 72 to move, limited by the slots of the double-slot frame 73 for restricting the movement of the two linkage frames 72, the two symmetrically arranged arc-shaped baffles 63 abut against each other in the middle to block the slurry and protect the camera 65. As the slurry enters the gap and the air in the gap is evacuated, part of the slurry passes through the opening formed by the separation of the plug body 71 from the outer housing 58 and enters the outer housing 58.

[0045] Embodiment 2, on the basis of Embodiment 1, refer to Figure 7 and Figure 9, the card slot leak prevention part 13 includes a pressurizing air pump 74 fixedly installed in the protective shell 8. The pressurizing air pump 74 is provided with a pressure measuring module. The pressurizing air pump 74 is fixedly connected with a four-way reversing valve 75. The four-way reversing valve 75 is fixedly connected with an air extraction pump 76. The four-way reversing valve 75 is fixedly connected with a first air pipe 77. The first air pipe 77 is fixedly connected with an annular airbag 78. The annular airbag 78 is slidably connected with the protective sleeve 51. The annular airbag 78 is fixedly connected with the protective shell 8. The four-way reversing valve 75 is fixedly connected with a second air pipe 79. The second air pipe 79 is fixedly connected with a hollow frame 80. The hollow frame 80 is slidably connected with a plurality of extension bars 81. The four-way reversing valve 75 is used to control the mutual communication states among the air extraction pump 76, the pressurizing air pump 74, the first air pipe 77 and the second air pipe 79. The pressurizing air pump 74 inflates the first air pipe 77 and the second air pipe 79 respectively through the four-way reversing valve 75, so as to increase the air pressure in the hollow frame 80 and push the extension bars 81 into the gap wall. As the gas enters the annular airbag 78 along the first air pipe 77, the inflated annular airbag 78 blocks the slurry from flowing into the protective shell 8. The air extraction pump 76 is used for air extraction operation. The air extraction pump 76 extracts air from the first air pipe 77 and the second air pipe 79 respectively through the four-way reversing valve 75 to perform a decompression operation on the annular airbag 78 and the hollow frame 80.
