Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to mobile grouting equipment for water conservancy and hydropower construction. Background Art

[0002] During water conservancy and hydropower construction, grouting is often used to pressurize slurry into the cracks of the foundation rock and soil to improve its integrity and impermeability, thereby improving foundation conditions and ensuring the safe operation of hydraulic structures. This typically involves drilling a hole in the ground, then injecting the grouting slurry into the hole, allowing it to flow along the borehole into the cracks below.

[0003] General equipment can only realize the release of slurry. In practice, small cracks will appear on the borehole wall. The opening of this crack is narrow and the depth is long. When the actual slurry flows into this crack, 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 air pressure in the air cavity blocking the slurry, the slurry cannot flow further into the depth of the gap, resulting in incomplete grouting and reduced quality of grouting construction.

[0036] A central grouting structure 2 connected to the bracket 1, wherein the central grouting structure 2 is connected to an external slurry supply device;

[0037] A position adjustment release structure 3 connected to the bracket 1, the position adjustment release structure 3 includes an angle adjustment movable portion 4 connected to the bracket 1, and the angle adjustment movable portion 4 is connected to a vertical release portion 5;

[0038] The gap negative pressure structure 6 connected to the vertical release part 5 includes a rectangular sleeve 7 movably connected to the vertical release part 5, the rectangular sleeve 7 is fixedly connected to a protective shell 8, the protective shell 8 is connected to a negative pressure suction part 9, the negative pressure suction part 9 is connected to 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 to a card seam leak-proof part 13, the card seam leak-proof part 13 is connected to the elastic extension part 10, the protective shell 8 is connected to a pull rope 14, the outer wall of the protective shell 8 is fixedly connected to an anti-rollover bracket 83, and a plurality of electric telescopic frames 84 are fixedly installed in the protective shell 8. The relative position of the gap negative pressure structure 6 and the gap in the borehole wall is adjusted by 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 gap negative pressure structure 6 by the vertical release part 5.

[0039] When in use, the bracket 1 is set up above the drill hole to be grouted, and the gap negative pressure structure 6 is suspended above the drill hole, and 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 toward the gap on the drill hole wall, and the card seam leak-proof part 13 is inserted into the gap wall. During this period, due to the provision of the anti-turnover bracket 83, when the protective shell 8 has a tendency to rotate, the anti-turnover bracket 83 abuts against the drill hole wall and the card seam leak-proof part 13 engages with the gap wall to limit the rotation of the protective shell 8, and then the elastic extension part 10 extends into the gap, and the vertical release part 5 and the rectangular sleeve 7 are separated from each other. After the gap negative pressure structure 6 is installed on the gap where the position adjustment release structure 3 is required to be installed The central grouting structure 2 performs grouting operations on the borehole, causing the slurry to fall into the borehole and flow, and because the independent power supply 12 supplies power to the negative pressure suction part 9, the negative pressure suction part 9 performs a negative pressure extraction operation through the elastic extension part 10, 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, thereby improving the grouting effect. When the gap negative pressure structure 6 needs to be removed, the control panel controls the extension of the electric telescopic frame 84 through the wireless communication module 11, while the card seam leak prevention part 13 actively contracts, so that the extended electric telescopic frame 84 pushes the borehole wall, so that the protective shell 8 is away from the gap, so that the personnel can pull the gap negative pressure structure 6 out of the borehole by lifting the pull rope 14. The present invention cooperates with each other among the central grouting structure 2, the position adjustment release structure 3, and the gap negative pressure structure 6 to facilitate the smooth flow of slurry into the gap, thereby improving the quality of grouting construction.

[0040] In one case of this embodiment, the central grouting structure 2 includes a double-outlet shaft motor 15 fixedly connected to the bracket 1, and the output end of the double-outlet shaft motor 15 is fixedly connected to a swing arm 16, and the swing arm 16 is fixedly connected to a slurry head 17. The slurry head 17 is provided with an internal thread, and the internal thread of the slurry head 17 is used to connect to the feeding pipe. The double-outlet shaft motor 15 drives the swing arm 16 to rotate, and the rotating swing arm 16 drives the slurry outlet of the slurry head 17 toward the borehole, so that the slurry head 17 can put the slurry into the borehole. When the angle adjustment moving part 4 and the vertical release part 5 need to be used, the double-outlet shaft motor 15 drives the swing arm 16 to rotate, so that the slurry head 17 is away from the borehole, providing space for the movement of the vertical release part 5.

[0041] In one case of this embodiment, the angle adjustment movable part 4 includes a limit ring 18 fixedly connected to the bracket 1, and an annular limit groove 19 is provided in the limit ring 18. The annular limit groove 19 is rotatably connected to a through slot frame 20, and a through hole is provided on the through slot frame 20 for accommodating the pulping head 17. The through slot frame 20 is fixedly connected to a ring gear 21, and 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 ring gear 21. The through slot frame 20 is fixedly connected to a track plate 23. The track plate 23 is provided with multiple groups of dovetail grooves. 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 frame 25 that is slidably connected to the dovetail groove. The parallel frame 25 is connected to the vertical release part 5. The first motor 22 drives the gear 82 to rotate, and the rotating gear 82 drives the ring gear 21 to rotate. The rotating ring gear 21 drives the through-slot frame 20 to rotate along the annular limit groove 19, and the through-slot frame 20 drives the track plate 23 to rotate. The first active telescopic rod 24 adjusts the position of the vertical release part 5 by driving the parallel frame 25 to slide along the dovetail groove.

[0042] In one case of this embodiment, the vertical release portion 5 includes two symmetrically arranged first active telescopic frames 26, 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 the first wheel frame 27, two sets of auxiliary wheels 28 are rotatably mounted on the first wheel frame 27, a driving wheel 29 is provided between the two sets of auxiliary wheels 28, the first wheel frame 27 is fixedly connected to the second motor 30, the output shaft of the second motor 30 is coaxially fixedly connected to the driving wheel 29, and the parallel frame 25 is fixedly connected to the first wheel frame 27. 5 is fixedly connected to two sets of symmetrically arranged second active telescopic frames 31, the mobile end of the second active telescopic frame 31 is fixedly connected to the 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 wheels 29, and the auxiliary wheels 28 are commonly connected to a splicing hoisting assembly 35, the splicing hoisting assembly 35 includes multiple sets of rectangular splicing bars 36 arranged in the vertical direction, the first abutting wheels 33, the second abutting wheels 34, the driving wheels 29, and the auxiliary wheels 28. The connecting wheel 34 and the auxiliary wheel 28 provide limiting guidance for the rectangular splicing strip 36 by abutting against the rectangular splicing strip 36. The rotating driving wheel 29 moves the rectangular splicing strip 36 by rubbing the rectangular splicing strip 36. A threaded hole 37 is provided at one end of the rectangular splicing strip 36. A threaded shaft 38 is fixedly installed at the other end of the rectangular splicing strip 36. The threaded shaft 38 arranged at the bottom of the splicing hoisting assembly 35 is threadedly connected to a double-head frame 39. The double-head frame 39 is movably connected to a group of rectangular splicing strips 36. The double-head frame 39 is fixed. Two groups of third active telescopic frames 40 are connected, and the movable ends of the third active telescopic frames 40 are movably connected to the rectangular sleeve 7. The threaded holes 37 on one group of splicing lifting components 35 are threadedly connected to the threaded shafts 38 on another adjacent splicing lifting component 35. As the threaded holes 37 are threadedly connected to the threaded shafts 38, the ends of the two groups of rectangular splicing strips 36 abut against each other. Under the pressure between the two groups of rectangular splicing strips 36, the maximum friction between the two groups of rectangular splicing strips 36 is increased to prevent the two groups of rectangular splicing strips 36 from freely rotating relative to each other. By threading the threaded hole 37 and the threaded shaft 38 together, the two sets of rectangular splicing strips 36 are docked, thereby extending the length of the splicing hoisting assembly 35. When the second motor 30 drives the driving wheel 29 to rotate and the driving wheel 29 abuts the rectangular splicing strip 36, the splicing hoisting assembly 35 moves, and since the third active telescopic frame 40 extends into the rectangular sleeve 7, the splicing 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 frame 27 moves away from each other, and the second wheel frame 32 moves away from each other, thereby providing space for disassembling the rectangular splicing strip 36.

[0043] In one case of this embodiment, the negative pressure suction part 9 includes a negative pressure box 41 fixedly connected to the protective shell 8, and an isolation plate 42 is slidably installed in the negative pressure box 41.

The negative pressure box 41 is threadedly connected with a sealing cover. As the sealing cover is opened, the negative pressure chamber 44 is connected to the external environment to facilitate the cleaning of the negative pressure chamber 44.

The control valve 46 is fixedly installed in the protective shell 8. A water pump 47 is fixedly installed in the water chamber 43. The water pump 47 is fixedly connected to a water bag 49 through a second pipe 48. The water bag 49 has elastic elasticity. 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 chamber 43. The water bag 49 is arranged in the protective shell 8. When the water pump 47 extracts water from the water chamber 43, the water flow is injected into the water bag 49 through the diversion of the second pipe 48, 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. Due to the drop in the water level in the water chamber 43, the isolation plate 42 slides down, and the volume of the negative pressure chamber 44 increases, so that a negative pressure is formed in the negative pressure chamber 44, and then the negative pressure chamber 44 is evacuated through the first pipe 45. At this time, the control valve 46 is opened, the elastic extension part 10 is connected to the first pipe 45, and 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 chamber 43 along the second pipe 48.

Since the first connector 56 is connected to the second connector 57 and the protective cover 51, as the protective cover 51 moves toward the inside of the gap, the first connector 56 drives the outer shell 58 to move toward the inside of the gap through the second connector 57. Since the outer shell 58 is fixedly connected to the spherical shell 59, the spherical shell 59 slides on all surfaces of the gap. During this period, the lighting lamp 62 performs lighting operations and the camera 65 performs video operations. As the control valve 46 is opened and the negative pressure extraction operation is carried out, negative pressure is formed in the gap between the center shell 60 and the outer shell 58. At this time, under the action of air pressure, the plug 71 moves into the outer shell 58, and since the plug 71 drives the moving frame 69 to move, the linkage gear 67 is in the second The rack 68 rolls on the linkage gear 67 that rolls during movement 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 into the column shell 61, and as the pulling frame 64 separates from the arc baffle 63, under the push of the return spring, the arc baffles 63 approach each other until the two symmetrically arranged groups of arc baffles 63 abut against each other, so that the enclosed space in the column shell 61 protects the camera 65, and because the arc baffle 63 drives the linkage frame 72 to move, the movement of the two groups of linkage frames 72 is restricted by the groove of the double-slot frame 73. Therefore, the two symmetrically arranged groups of arc baffles 63 abut against each other to block the slurry and protect the camera 65. As the slurry enters the gap and the air in the gap is extracted, part of the slurry passes through the opening formed by the plug body 71 separating from the outer shell 58 and enters the outer shell 58.

[0045] Example 2, based on Example 1, refer to Figure 7 and Figure 9The card seam leak-proof part 13 includes a pressurized air pump 74 fixedly installed in the protective shell 8, and the pressurized air pump 74 has a pressure measuring module. The pressurized air pump 74 is fixedly connected to a four-way reversing valve 75, and the four-way reversing valve 75 is fixedly connected to an air pump 76. The four-way reversing valve 75 is fixedly connected to a first air pipe 77, and the first air pipe 77 is fixedly connected to an annular airbag 78. The annular airbag 78 is slidably connected to the protective cover 51, and the annular airbag 78 is fixedly connected to the protective shell 8. The four-way reversing valve 75 is fixedly connected to a second air pipe 79, and the second air pipe 79 is fixedly connected to a hollow frame 80. The hollow frame 80 is slidably connected to multiple groups of extension strips 81. The four-way reversing valve 75 is used to control the interconnection status among the vacuum pump 76, the pressurized air pump 74, the first air pipe 77, and the second air pipe 79. The pressurized air pump 74 inflates the first air pipe 77 and the second air pipe 79 respectively through the four-way reversing valve 75 to increase the air pressure in the hollow frame 80, so as to push the extension strip 81 to the gap wall. As the gas enters the annular airbag 78 along the first air pipe 77, the expanded annular airbag 78 blocks the slurry from flowing into the protective shell 8. The vacuum pump 76 is used to perform the vacuum operation. The vacuum pump 76 vacuums the first air pipe 77 and the second air pipe 79 respectively through the four-way reversing valve 75 to decompress the annular airbag 78 and the hollow frame 80.
