Description

Technical Field

[0001] The present invention relates to the technical field of grouting material fullness detection, and in particular to a grouting material fullness detection device and method based on conductivity difference. Background Art

[0002] The grouting material fullness detection device is a special tool used to measure and evaluate the fullness of grouting materials. In construction, the grouting fullness is directly related to the stability and safety of the building structure, so this type of detection device plays a vital role.

[0003] The fullness of the grouting material is often tested by the conductivity test method. This method evaluates the saturation of the grouting material by measuring its conductivity. When in liquid state, the grouting material has a high conductivity because it contains a large number of freely moving ions. After solidification, the movement of ions is restricted and the conductivity is significantly reduced. Based on this principle, the fullness of the grouting material can be judged by measuring the conductivity at different positions: higher conductivity may indicate that the grouting material has not yet solidified or has been incompletely solidified, with voids or is not fully filled. Lower conductivity indicates that the grouting material has been solidified and is fully filled. However, in the prior art, the staff cannot flexibly adjust the measurement position of the electrode sheet during the detection process, which limits the flexibility and accuracy of the detection, making it difficult to comprehensively and accurately evaluate the fullness of the grouting material in complex or specific situations.

[0016] The present invention has the following beneficial effects: 1. When adjusting the position of the second conductive block, the staff can pull the positioning rod to retract it into the slider hole, and then pull the slider to move in the installation opening. The movement of the slider drives the second conductive block to move. When the second conductive block moves to the position facing the first conductive block, the positioning rod is reset under the elastic force of the connecting spring and inserted into the positioning sleeve. The positioning rod and the positioning sleeve jointly position the slider, thereby fixing the position of the second conductive block. This design greatly facilitates the staff to flexibly and quickly adjust the position of the second conductive block, thereby realizing the rapid detection of the conductivity of different positions of the grouting material, and improving the detection efficiency and accuracy; 2. When the second injection barrel rotates, the assembly frame drives the shaft and the gear to rotate. The gear rotates by itself because it is in meshing state with the rack, and then drives the shaft and the eccentric wheel to rotate. The eccentric wheel continuously hits the second injection barrel during rotation, effectively loosening the solidified grouting material in the cylindrical structure. This design greatly facilitates the subsequent separation of the solidified grouting material from the cylindrical structure, improves the efficiency of the stripping process, reduces the difficulty of operation, and ensures the smooth progress of the entire stripping process. 3. When the first injection barrel and the second injection barrel are combined together, the staff sets the upper snap ring on the top and rests it on the two limit lips, and sets the lower snap ring on the annular structure formed by the two fixed frames to achieve a firm fixation of the first injection barrel and the second injection barrel. This design effectively avoids the existence of a gap between the two, thereby preventing the leakage of grouting material, ensuring the stability and reliability of the grouting process, and improving work efficiency and safety.

The movable seat 104 is slidably assembled on the bracket 101. A motor fixing frame is installed on the bracket 101. One of the mounting frames 105 is fixed to one end of the bracket 101 close to the motor fixing frame, and the other mounting frame 105 is fixed to the movable seat 104. The opening and closing unit also includes a motor 102 and a screw rod 103. The motor 102 is installed on the motor fixing frame, and the screw rod 103 is rotatably installed on the bracket 101.

The injection unit is arranged between the two mounting frames 105, and the injection unit includes a first injection barrel 21 and a second injection barrel 22. The first injection barrel 21 and the second injection barrel 22 have the same shape, and the first injection barrel 21 and the second injection barrel 22 together form a tubular structure, and the top of the tubular structure is open. The injection unit also includes two first fixing frames 23, two second fixing frames 24 and two fixing rods 25. The two first fixing frames 23 are respectively fixed to the middle positions of the first injection barrel 21 and the second injection barrel 22, and the two second fixing frames 24 are respectively fixed to the bottom ends of the first injection barrel 21 and the second injection barrel 22. The two fixing rods 25 are respectively fixed to the two second fixing frames 24, and the two fixing rods 25 are respectively rotatably installed on the two mounting frames 105. In the initial state, the first injection barrel 21 and the second injection barrel 22 are in a state of being separated from each other. Fig. 9 As shown, first, the staff starts the motor 102, and when the motor 102 is running, it drives the screw rod 103 to rotate, and when the screw rod 103 rotates, it drives the moving seat 104 to move, and when the moving seat 104 moves, the mounting frame 105 connected to the moving seat 104 moves accordingly, so that the two mounting frames 105 are close to each other. In this process, the second injection barrel 22 will move in the direction close to the first injection barrel 21 until the first injection barrel 21 and the second injection barrel 22 together form a cylindrical structure; The top of the first injection barrel 21 and the second injection barrel 22 are fixed with a limit lip 71, and the bottom of the first injection barrel 21 and the second injection barrel 22 are fixed with a fixed frame 72. Each fixed frame 72 is a semi-annular structure. The top of the cylindrical structure composed of the first injection barrel 21 and the second injection barrel 22 is sleeved with an upper clamping ring 73, and the upper clamping ring 73 is placed on the two limit lips 71. The two fixed frames 72 are jointly sleeved with a lower clamping ring 74. When the first injection barrel 21 and the second injection barrel 22 are combined together When the cam 72 is in the closed position, the staff will sleeve the upper snap ring 73 on the top of the first injection barrel 21 and the second injection barrel 22, so that the upper snap ring 73 is placed on the two limit lips 71, and then sleeve the lower snap ring 74 on the annular structure formed by the two fixing frames 72. In this state, the upper snap ring 73 and the lower snap ring 74 fix the first injection barrel 21 and the second injection barrel 22 to avoid a gap between the first injection barrel 21 and the second injection barrel 22, thereby preventing the grouting material from leaking. The detection unit is arranged on the first injection barrel 21, and the detection unit includes a detection component and a positioning component. The detection component includes a first electrode sheet 31, a plurality of through-holes 32, a plurality of first conductive blocks 33, a plurality of second electrode sheets 34 and a second conductive block 35. The first electrode sheet 31 is fixed to the inner bottom surface of the first injection barrel 21, and the plurality of through-holes 32 are all opened on the first injection barrel 21. The plurality of through-holes 32 are distributed in a linear array along the height direction of the first injection barrel 21. The plurality of first conductive blocks 33 are respectively fixed in the plurality of through-holes 32, and the plurality of second electrode sheets 34 are respectively fixed on the plurality of first conductive blocks 33. Each second electrode sheet 34 is arranged in the first injection barrel. 21, the second conductive block 35 is arranged on one side of the first injection barrel 21, and the staff can adjust the position of the second conductive block 35 so that the corresponding second electrode sheet 34 forms a current path with the first electrode sheet 31. When the second conductive block 35 moves to the position of one of the first conductive blocks 33, the second conductive block 35 will contact the first conductive block 33. A support plate is fixed on the side of the bracket 101, and a conductivity detector is installed on the support plate. The first electrode sheet 31 and the second conductive block 35 are connected to the conductivity detector through a wire, so that the staff can detect the conductivity of different positions of the grouting material and judge the saturation of the grouting material by the conductivity. The positioning assembly includes a connecting frame 41, a slider 43, a limit plate 44, a positioning rod 45 and a plurality of positioning sleeves 48. The connecting frame 41 is fixed on the outer circumference of the first injection barrel 21, and a mounting port 42 is provided on the connecting frame 41. The slider 43 is fixed on the side of the second conductive block 35, and the slider 43 slides in the mounting port 42. The limit plate 44 is fixedly sleeved on the slider 43. The limit plate 44 and the second conductive block 35 are respectively located on both sides of the connecting frame 41, and the limit plate 44 and the second conductive block 35 are both fitted with the connecting frame 41. A hole is provided on the slider 43, and the positioning rod 45 is movably inserted in the hole. One end of the positioning rod 45 is fixedly sleeved on the slider 43. The fixed sleeve is provided with a collar 46, and the collar 46 is connected to the slider 43 through a connecting spring 47. A plurality of positioning sleeves 48 are fixed on the side of the connecting frame 41, and the plurality of positioning sleeves 48 are distributed in a linear array along the height direction of the connecting frame 41. The plurality of positioning sleeves 48 are respectively arranged opposite to the plurality of first conductive blocks 33. The positioning rod 45 and the positioning sleeve 48 play a positioning role in positioning the position of the slider 43. When the position of the slider 43 is fixed, the position of the second conductive block 35 is also fixed. This design facilitates the staff to flexibly and quickly adjust the position of the second conductive block 35, so as to quickly detect the conductivity of different positions of the grouting material. The guide unit is composed of two guide components, which are arranged on two mounting frames 105 respectively. The guide components include a guide frame 51, a guide opening 52, a guide rod 53 and two limit rings 54. The guide frame 51 is fixed to the side of the mounting frame 105, and the guide frame 51 is an arc-shaped structure. The guide opening 52 is opened on the guide frame 51, and the guide rod 53 is fixed to the side of the first fixing frame 23. One end of the guide rod 53 away from the first fixing frame 23 extends into the guide opening 52. The two limit rings 54 are fixedly sleeved on the guide rod 53 away from the first fixing frame 23. 3, two limiting rings 54 are respectively located on both sides of the guide frame 51, and the two limiting rings 54 are both fitted with the guide frame 51. The staff rotates the cylindrical structure composed of the first injection barrel 21 and the second injection barrel 22 to make the cylindrical structure rotate around the two fixing rods 25. In this process, the two first fixing frames 23 also rotate accordingly, so that the two guide rods 53 slide in the two guide openings 52 respectively. The two guide rods 53 and the two guide openings 52 provide a limit for the rotation of the cylindrical structure, ensuring the stability of the cylindrical structure during rotation; The vibration unit includes a vibration component and an arc-shaped rack 65. The vibration component is arranged on the second injection barrel 22. The vibration component includes an assembly frame 61, a shaft 62, an eccentric wheel 63 and a gear 64. The assembly frame 61 is fixed on the first fixed frame 23 on the second injection barrel 22. The shaft 62 is rotatably assembled on the assembly frame 61. The eccentric wheel 63 is fixedly sleeved on the shaft 62, and the eccentric wheel 63 is eccentrically arranged with respect to the shaft 62. The eccentric wheel 63 is made of rubber material. The gear 64 is fixedly sleeved on the shaft 62, and the gear 64 is eccentrically arranged with respect to the arc-shaped rack 65. The arc-shaped rack 65 is meshed with the arc-shaped rack 65, and the arc-shaped rack 65 is fixed on the corresponding guide frame 51 through two connecting rods 66. The gear 64 always keeps meshing with the rack during the process of following the rotation of the second injection barrel 22, so that the gear 64 can rotate on itself and drive the shaft 62 to rotate. When the shaft 62 rotates, it drives the eccentric wheel 63 to rotate. During the rotation, the eccentric wheel 63 can continuously knock the second injection barrel 22 to loosen the solidified grouting material in the cylindrical structure, so as to facilitate the subsequent separation of the solidified grouting material from the cylindrical structure.

[0021] The specific working principle of the present invention is as follows: When the grouting material fullness detection device based on conductivity difference proposed by the present invention is used, in the initial state, the first injection barrel 21 and the second injection barrel 22 are in a state of being separated from each other, such as Fig. 9 As shown, first, the staff starts the motor 102. When the motor 102 is running, it drives the screw rod 103 to rotate. When the screw rod 103 rotates, it drives the moving seat 104 to move. When the moving seat 104 moves, the mounting frame 105 connected to the moving seat 104 moves accordingly, so that the two mounting frames 105 are close to each other. In this process, the second injection barrel 22 will move in the direction close to the first injection barrel 21 until the first injection barrel 21 and the second injection barrel 22 form a cylindrical structure together. At this time, the staff turns off the motor 102 and injects grouting material into the cylindrical structure. After the grouting material is solidified, the staff uses the detection unit to detect the saturation of the grouting material; For the detection unit, a first electrode sheet 31 is provided at the inner bottom of the first injection barrel 21, and a plurality of second electrode sheets 34 are also provided inside the first injection barrel 21. The staff can adjust the position of the second conductive block 35 so that the corresponding second electrode sheet 34 forms a current path with the first electrode sheet 31. When the second conductive block 35 moves to the position of one of the first conductive blocks 33, the second conductive block 35 will contact the first conductive block 33. A support plate is fixed on the side of the bracket 101, and a conductivity detector is installed on the support plate. The first electrode sheet 31 and the second conductive block 35 are connected to the conductivity detector through a wire, so that the staff can detect the conductivity of different positions of the grouting material and judge the saturation of the grouting material by the conductivity. The specific detection principle is the existing technology, which is not shown in the figure and will not be described in detail here. When adjusting the position of the second conductive block 35, The staff first pulls the positioning rod 45 to retract the positioning rod 45 into the hole on the slider 43, and then pulls the slider 43 to move the slider 43 in the installation port 42. When the slider 43 moves, the second conductive block 35 moves accordingly. When the second conductive block 35 moves to a position directly opposite to the first conductive block 33, the positioning rod 45 just moves to a position directly opposite to the corresponding positioning sleeve 48. At this time, the staff releases the positioning rod 45 to reset the positioning rod 45 under the elastic force of the connecting spring 47 and insert it into the directly opposite positioning sleeve 48. In this case, the positioning rod 45 and the positioning sleeve 48 play a positioning role on the position of the slider 43. When the position of the slider 43 is fixed, the position of the second conductive block 35 is also fixed. This design facilitates the staff to flexibly and quickly adjust the position of the second conductive block 35, so as to quickly detect the conductivity of different positions of the grouting material. After the inspection is completed, the staff removes the grouting material. Specifically, the staff rotates the cylindrical structure composed of the first injection barrel 21 and the second injection barrel 22 to make the cylindrical structure rotate around the two fixed rods 25. In this process, the two first fixed frames 23 also rotate accordingly, so that the two guide rods 53 slide in the two guide openings 52 respectively. The two guide rods 53 and the two guide openings 52 provide limits for the rotation of the cylindrical structure to ensure the stability of the cylindrical structure during rotation. In addition, two limit rings 54 are fixed to each guide rod 53. The two limit rings 54 are respectively located on both sides of the guide frame 51, and the two limit rings 54 are both fitted between the guide frame 51. The design of the limit ring 54 can prevent the guide rod 53 from falling off from the guide opening 52, further ensuring the stability of the cylindrical structure during rotation. When the two guide rods 53 rotate to the extreme position, the cylindrical structure just rotates to a horizontal state. When the cylindrical structure rotates, the vibration component arranged on the second injection barrel 22 plays a role. Specifically, when the second injection barrel 22 rotates, the assembly frame 61 thereon rotates accordingly. When the assembly frame 61 rotates, it drives the shaft rod 62 and the gear 64 to rotate. The gear 64 always keeps in meshing with the rack while following the rotation of the second injection barrel 22, so that the gear 64 can rotate on itself and drive the shaft rod 62 to rotate. When the shaft rod 62 rotates, it drives the eccentric wheel 63 to rotate. When the eccentric wheel 63 rotates, it can continuously knock the second injection barrel 22 during the rotation, so that the solidified grouting material in the cylindrical structure is loosened, so as to facilitate the subsequent solidified grouting material to be separated from the cylindrical structure. It should be noted that the eccentric wheel 63 is made of rubber material. This design can not only prevent the eccentric wheel 63 from damaging the second injection barrel 22 during the rotation, but also the deformable property of the rubber material can prevent the eccentric wheel 63 from causing motion interference with the second injection barrel 22. When the cylindrical structure rotates to a horizontal state, the staff controls the motor 102 to rotate in the reverse direction, so that the movable seat 104 moves in the reverse direction. The movable seat 104 can drive the mounting frame 105 thereon to move when moving in the reverse direction, so that the second injection barrel 22 moves in a direction away from the first injection barrel 21 until the first injection barrel 21 is separated from the second injection barrel 22. When the first injection barrel 21 is separated from the second injection barrel 22, the solidified grouting material between the first injection barrel 21 and the second injection barrel 22 will fall out and fall on the support plate, so as to realize the automatic removal of the grouting material. It should be noted that the first electrode sheet 31 is a thin sheet structure, which makes the contact area between the first electrode sheet 31 and the grouting material very small, so as to facilitate the separation of the first electrode sheet 31 from the grouting material. For the first injection barrel 21 and the second injection barrel 22, when the first injection barrel 21 and the second injection barrel 22 are combined together, the staff will sleeve the upper snap ring 73 on the top of the first injection barrel 21 and the second injection barrel 22, so that the upper snap ring 73 rests on the two limiting lips 71, and then sleeve the lower snap ring 74 on the annular structure formed by the two fixed frames 72. In this state, the upper snap ring 73 and the lower snap ring 74 fix the first injection barrel 21 and the second injection barrel 22, avoiding the existence of a gap between the first injection barrel 21 and the second injection barrel 22, thereby preventing the leakage of the grouting material.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
