[0001] The utility model belongs to the technical field of building construction, in particular to a wall hollowing detection device. Background Art

[0002] Wall hollowing generally refers to the phenomenon of cavities appearing between the wall and the mortar layer and plaster layer, which is usually caused by factors such as unclean wall base treatment and improper material ratio.

[0003] In order to verify the quality of wall construction, a wall hollowing detection device is usually used to detect the completed wall. Specifically, the wall is knocked by an external object. Since the sound produced by the collision at the hollow wall is different from that at the non-hollow wall, the sound characteristics produced during the collision can be used to determine whether there is a hollow inside the wall. If the hollow is detected, the wall within the corresponding range can be repaired. However, when performing hollow detection on the wall, the existing wall hollowing detection device has difficulty in detecting higher walls, which can easily lead to missed detection of high walls.

[0004] To this end, the utility model provides a wall hollowing detection device. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1As shown in the figure, a wall hollowing detection device described in an embodiment of the utility model comprises a mobile base 1; a lifting rod 12 is fixedly connected to the top of the mobile base 1; a mounting frame 13 is fixedly connected to the top of the lifting rod 12; a rotating rod 14 is rotatably connected to the inner side wall of the mounting frame 13; a toggle rod 15 is rotatably connected to the inner side wall of the mounting frame 13; a motor 16 is fixedly connected to the outer side wall of the mounting frame 13; the output end of the motor 16 is fixedly connected to the side wall of the toggle rod 15; a knocking ring 17 is fixedly connected to the top side wall of the rotating rod 14; a counterweight 18 is fixedly connected to the bottom of the rotating rod 14; a sound receiver 19 is fixedly connected to the side wall of the rotating rod 14; a processing mechanism 110 is fixedly connected to the top of the mobile base 1; when working, the device is moved to the wall where the hollowing inspection is required, so that the knocking ring 17 faces the wall, and then the motor 16 is started to drive the toggle rod 15 to rotate, and the rotating toggle rod 15 will turn the rotating rod 14 The lever 15 is then moved downwards, and after reaching a certain angle, the lever 15 is separated from the rotating lever 14. At this time, the rotating lever 14 rotates under the gravity of the counterweight 18, causing the knocking ring 17 to knock toward the wall. The sound generated by the knocking will be collected by the sound collector 19, and then the processing mechanism 110 analyzes the fluctuation of the sound to determine whether there is a hollow drum. Then, as the lifting rod 12 rises or falls, hollow drum detection can be performed on multiple walls. By setting the corresponding program and then placing the device near the wall, the device can complete automatic detection of the wall and present all the detection data on the processing mechanism 110. Through the above structure, hollow drum detection can be conveniently performed automatically on walls of different heights, saving manpower. In addition, intensive detection can be performed on various parts of the wall through program settings, thereby improving the detection range of hollow drum detection. The knocking sound can also be analyzed by the system to reduce the occurrence of misjudgment by personnel.

[0023] like Figure 1As shown in the figure, the side wall of the mounting frame 13 is rotatably connected with a pair of connecting rods 2; the side walls of the pair of connecting rods 2 are fixedly connected with a mounting plate 21; the side wall of the mounting plate 21 is fixedly connected with a first magnet 22; the side wall of the rotating rod 14 at one end of which the knocking ring 17 is fixedly connected with a second magnet 23; the side wall of the mounting frame 13 is provided with a slide groove 24; the middle part of the slide groove 24 is slidably connected with a bolt 25; during operation, when necessary, the connecting rod 2 is rotated to a specified position to shorten or approach the distance between the first magnet 22 and the second magnet 23, and at the same time, the bolt 25 is slid and tightened in the middle part of the slide groove 24 so that the bolt 25 is in the middle of the slide groove 24. The middle part is fixed and supports the mounting plate 21. When hollow drum detection is performed by knocking the knocking ring 17, after the toggle rod 15 is separated from the rotating rod 14, the second magnet 23 will push the knocking ring 17 away due to the repulsive force between the second magnet 22 and the first magnet 22, thereby increasing the knocking force on the wall. By adjusting the position of the first magnet 22 to increase or decrease the distance between the first magnet 22 and the second magnet 23, the knocking force of the knocking ring 17 can be adjusted. Through the above structure, the knocking force of the knocking ring 17 on the wall can be adjusted. According to different wall surfaces, it can be adjusted to a strength that will not damage the wall and can clearly record the sound of the sound receiver 19.

[0024] like Figure 1 As shown in the figure, the inner wall of the rotating rod 14 is fixedly connected to the electric cylinder 3; the output end of the electric cylinder 3 is arranged to face the knocking ring 17; the output end of the electric cylinder 3 is fixedly connected to the fixed plate 31; the side wall of the fixed plate 31 is fixedly connected to the ink block 32, and the diameter of the ink block 32 is smaller than the inner diameter of the knocking ring 17; during operation, when the processing mechanism 110 determines that there is a hollow at the current detection position, the ink block 32 is pushed out toward the end of the knocking ring 17 by extending the electric cylinder 3, and then as the knocking ring 17 is knocked again, the ink block 32 will contact the wall surface, and then leave a mark on the wall surface. Through the above structure, the hollow part can be conveniently marked, which is convenient for distinguishing the hollow part later.

[0025] like Figure 1 As shown in the figure, a mounting groove 4 is provided in the middle of the toggle rod 15; a plurality of first rollers 41 are rotatably connected to the middle of the side wall of the mounting groove 4; during operation, when the rotating rod 14 is toggled by rotating the toggle rod 15, the setting of the plurality of first rollers 41 can convert the sliding friction between the toggle rod 15 and the counterweight block 18 into rolling friction, thereby reducing the wear between the counterweight block 18 and the toggle rod 15 due to mutual friction.

[0026] like Figure 1As shown in the figure, the side walls of the movable base 1 and the side walls of the lifting rod 12 are fixedly connected with a fixing rod 5; both ends of the fixing rod 5 are rotatably connected with a second roller 51; during operation, when the device is close to the wall for hollow drum detection, multiple second rollers 51 are fitted with the wall, which can conveniently control the distance between the knocking ring 17 and the wall, and when the device moves along the wall and performs hollow drum detection, the second roller 51 will generate rolling friction with the wall. Through the above structure, the knocking ring 17 can be conveniently positioned, so that it can stably perform hollow drum inspection on the wall, while reducing the damage to the wall due to friction.

[0027] like Figure 1 As shown in the figure, an elastic membrane 6 is fixedly connected to the inner side of the knocking ring 17; a plurality of tiny holes are opened in the middle of the elastic membrane 6; during operation, as the ink block 32 moves, the end of the ink block 32 will squeeze the elastic membrane 6, and the elastic membrane 6 will elastically deform toward the end of the knocking ring 17 after being squeezed, and the pores in the middle of the elastic membrane 6 will open, at which time the ink contained in the ink block 32 can mark the wall through the pores in the middle of the elastic membrane 6, and after marking, the ink block 32 will withdraw backwards with the electric cylinder 3, and at the same time the elastic membrane 6 will return to its original state, and a plurality of pores will close, so that impurities generated during knocking cannot enter the interior of the knocking ring 17 to contaminate the ink block 32.

[0028] like Figure 1 As shown, the side wall of the mounting frame 13 is fixedly connected to the limiting column 7; the limiting column 7 is located at the maximum inclination angle of the upper half of the rotating rod 14; during operation, when the position of the first magnet 22 is adjusted by rotating the connecting rod 2, the limiting column 7 will limit the rotation angle of the connecting rod 2 to prevent the connecting rod 2 from being excessively adjusted, causing the rotation stroke of the rotating rod 14 to be blocked by the mounting plate 21, thereby causing the rotating rod 14 and the toggle rod 15 to be stuck with each other.

[0029] During operation, move the device to the wall where hollow drum inspection is required, with the knocking ring 17 facing the wall. Then start the motor 16 to drive the toggle rod 15 to rotate. The rotating toggle rod 15 will push the lower part of the rotating rod 14. After reaching a certain angle, the toggle rod 15 will separate from the rotating rod 14. At this time, the rotating rod 14 will rotate back under the action of the gravity of the counterweight 18, so that the knocking ring 17 knocks against the wall. The sound generated by the knocking will be collected by the sound collector 19, and then the processing mechanism 110 will analyze the sound wave to determine whether there is a hollow drum. Then, as the lifting rod 12 rises or falls, the hollow drum detection can be carried out on multiple walls. By setting the corresponding program and then placing the device near the wall, the device can complete the automatic detection of the wall and present all the detection data on the processing mechanism 110. When needed, rotate the connecting rod 2 to the designated position to shorten or approach the distance between the first magnet 22 and the second magnet 23. At the same time, slide the bolt 25 in the middle of the chute 24 and tighten it to fix the bolt 25 in the middle of the chute 24 and support the mounting plate 21. When carrying out hollow drum detection through the knocking of the knocking ring 17, after the toggle rod 15 separates from the rotating rod 14, the second magnet 23 will push the knocking ring 17 away due to the repulsive force between it and the first magnet 22, thereby increasing the knocking force on the wall. By adjusting the position of the first magnet 22 to increase or decrease the distance between the first magnet 22 and the second magnet 23, the knocking force of the knocking ring 17 can be adjusted. When the processing mechanism 110 determines that there is a hollow drum at the current detection location, the ink block 32 is pushed out towards the end of the knocking ring 17 by the extension of the electric cylinder 3. Then, with the repeated knocking of the knocking ring 17, the ink block 32 will come into contact with the wall, leaving a mark on the wall. When the rotating rod 14 is pushed by the rotation of the toggle rod 15, the setting of multiple first rollers 41 can convert the sliding friction between the toggle rod 15 and the counterweight 18 into rolling friction. When the device is close to the wall for hollow drum detection, multiple second rollers 51 are attached to the wall, which can easily control the distance between the knocking ring 17 and the wall. And when the device moves along the wall for hollow drum detection, the second rollers 51 will generate rolling friction with the wall. As the ink block 32 moves, the end of the ink block 32 will squeeze the elastic membrane 6. After being squeezed, the elastic membrane 6 will elastically deform towards the end of the knocking ring 17 and open the fine holes in the middle of the elastic membrane 6. At this time, the ink liquid contained in the ink block 32 can mark the wall through the fine holes in the middle of the elastic membrane 6. After the marking is completed, the ink block 32 will retreat backward with the electric cylinder 3, and at the same time, the elastic membrane 6 will return to its original state and the multiple fine holes will close, so that the impurities generated during knocking cannot enter the inside of the knocking ring 17 to contaminate the ink block 32.
