Description

Technical Field

[0001] The invention belongs to the field of building engineering wall detection, and in particular relates to a building engineering wall quality detector. Background Art

[0002] At present, during the use of concrete, it is inevitable that different degrees of aging and disease phenomena will occur. For example, the concrete will show obvious carbonization, which will cause the protective layer of the steel bars to be thin and cause steel bar rust expansion joints. At this stage, the protection of concrete is usually to apply protective materials on the concrete surface, such as SBR mortar or protective coatings such as epoxy coatings and chlorosulfonated polyethylene coatings. After the protective coating is completed, in order to determine the bonding strength between the protective coating and the concrete surface, a special wall quality tester is used to test it.

[0003] Most of the existing wall quality detectors detect the strength of the wall by applying a certain pressure to the wall. When the strength of the wall is unqualified, a dent will appear on the wall. The inspector judges the quality of the wall by observing the size and depth of the dent. However, when the dent is small, it is difficult for the inspector to observe it and it is easy to ignore the dent, resulting in low accuracy of the test result. After the test is completed, the test instrument needs to be removed so that the inspector can observe whether there is a dent in the wall, which wastes time and reduces the test efficiency.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-Figure 7As shown, a construction engineering wall quality detector provided by the present invention includes a mounting plate 5, a handle 4 is fixedly connected to the top of the mounting plate 5, and fixed tubes 2 are fixedly connected to both ends of the bottom of the mounting plate 5. Shrinkage tubes 12 are slidably connected to the inside of the two fixed tubes 2, and a fifth compression spring 17 is connected between the shrinkage tube 12 and the fixed tube 2. A rubber ring 13 is fixedly connected to the bottom of the two shrinkage tubes 12. An air pressure sensor 16 is arranged inside the fixed tube 2. A first display 1 is installed on the top of the mounting plate 5. The first display 1 is electrically connected to the air pressure sensor 16. The first display 1 is used to display the air pressure inside the fixed tube 2. A connecting hole 18 connected to the inside of the two fixed tubes 2 is opened inside the handle 4. A vacuum pump 3 is fixedly installed on the top of the mounting plate 5, and the output end of the vacuum pump 3 is connected to the connecting hole 18. A detection head 9 is fixedly connected to the bottom of the mounting plate 5, and the end of the detection head 9 is spherical. It also includes:

[0033] A detection component 15, the detection component 15 is installed inside the detection head 9, a second display 10 is installed on the top of the mounting plate 5, the detection component 15 is electrically connected to the second display 10, and the detection component 15 is used to detect the pressure of the detection head 9 on the wall;

[0034] Two constant pressure mechanisms 11 are respectively installed on two shrinking cylinders 12. The distance from the upper end surface of the constant pressure mechanism 11 to the bottom of the fixed cylinder 2 is the same as the distance from the end of the detection head 9 to the bottom of the fluid seal 14. When the end surface of the detection head 9 contacts the wall, the constant pressure mechanism 11 is used to prevent the fixed cylinder 2 from moving, so that the mounting plate 5 and the detection head 9 can accumulate force, and then the wall can be tested for constant pressure, so that the detection result is more accurate.

[0035] During the inspection, hold the handle 4 and place the fluid seal 14 parallel to the wall, then start the vacuum pump 3, the vacuum pump 3 draws the air in the connecting hole 18 and the fixed tube 2, the pressure in the fixed tube 2 decreases, and under the action of atmospheric pressure, the fixed tube 2 moves toward the wall, that is, the shrink tube 12 retracts into the inside of the fixed tube 2, when the bottom of the fixed tube 2 hits the constant pressure mechanism 11, the constant pressure mechanism 11 blocks the movement of the fixed tube 2, at this time, the ends of the detection head 9 and the detection assembly 15 are in contact with the wall, the vacuum pump 3 continues to draw the air inside the fixed tube 2, the pressure in the fixed tube 2 gradually decreases, when the pressure in the fixed tube 2 reaches a certain value, turn off the vacuum pump 3, and then release the blocking of the fixed tube 2 by the constant pressure mechanism 11, under the action of atmospheric pressure, the fixed tube 2, the mounting plate 5 and the detection head 9 have a tendency to move toward the wall, and the detection head 9 will drive the detection The measuring component 15 applies a certain pressure to the wall, and the wall can be tested at a constant pressure. When the wall quality is unqualified, the wall will be squeezed and deformed by the measuring component 15, thereby forming a depression, and the measuring component 15 and the measuring head 9 will move with the depression, and the measuring head 9 will drive the mounting plate 5 and the fixed cylinder 2 to move. Since the molecular weight of the air in the fixed cylinder 2 remains unchanged, its volume decreases, which will increase the pressure in the fixed cylinder 2. The pressure in the fixed cylinder 2 detected by the air pressure sensor 16 will be displayed on the first display 1, and it can be judged according to the reading of the first display 1. When the reading on the first display 1 changes (increases), the wall at this place is unqualified. When the reading of the first display 1 remains unchanged, the wall quality at this place is qualified. Since the air pressure sensor 16 has a high accuracy, even if the depression is small, it can be detected, and the detection accuracy is greatly improved.

[0036] The detection component 15 detects the pressure of the detection head 9 on the wall and displays the detected value on the second display 10. Under the reaction force, the pressure on the wall at this time can be determined.

[0037] like Figure 2-Figure 4 As shown, a construction engineering wall quality detector provided by the present invention, in this embodiment, the detection component 15 includes a mounting groove 153 opened on the side of the detection head 9, the interior of the mounting groove 153 is slidably connected with a detection column 154, the detection column 154 can be completely retracted into the interior of the mounting groove 153, a fourth compression spring 152 is connected between the detection column 154 and the detection head 9, and a pressure sensor 151 is arranged on the top of the mounting groove 153, and the pressure sensor 151 is electrically connected to the second display 10.

[0038] The pressure sensor 151 detects the pressure on the detection column 154 . Under the reaction force, the detection column 154 is subjected to the force from the wall.

[0039] like Figure 1-Figure 2 and Figure 5-Figure 6As shown, a construction engineering wall quality detector provided by the present invention, in this embodiment, the constant pressure mechanism 11 includes a fixed box 112 fixedly connected to the side of the shrink tube 12, the fixed box 112 is internally slidably connected with an abutment block 111, a third compression spring 118 is connected between the abutment block 111 and the fixed box 112, the top of the abutment block 111 extends out of the fixed box 112, the side of the fixed box 112 is fixedly connected to a limiting box 113, the limiting box 113 is internally slidably connected to a limiting block 116, a second slot 119 is provided on the side of the abutment block 111, one end of the abutment block 111 is plugged into the second slot 119, the limiting block 116 and the limiting spring 118 are connected to the fixing box 112, the fixing box 112 is fixedly connected to a limiting box 113, the limiting box 113 is internally slidably connected to a limiting block 116, a second slot 119 is provided on the side of the abutment block 111, one end of the abutment block 111 is plugged into the second slot 119, and the limiting block 116 and the limiting spring 118 are connected to the fixing box 112. A second compression spring 117 is connected between the boxes 113, and a pull column 114 is fixedly connected to the side of the limit block 116. The pull column 114 passes through one end of the limit box 113 and is fixedly connected to the limit baffle 115. When the limit block 116 is inserted into the second slot 119, the distance from the top of the abutment block 111 to the bottom of the fixed cylinder 2 is the same as the distance from the end of the detection head 9 to the bottom of the fluid seal 14, that is, when the fixed cylinder 2 is blocked by the abutment block 111, the ends of the detection head 9 and the detection column 154 are both in abutment with the wall. At this time, the force between the detection head 9 and the wall is zero, and the force between the wall and the detection column 154 is the elastic force of the fourth compression spring 152, and its pressure value is kept unchanged.

[0040] By pulling the pull column 114, the limit block 116 can be pulled out from the second slot 119, and the abutment block 111 no longer blocks the fixed tube 2. Under the action of atmospheric pressure, when the wall is unqualified, the detection head 9 and the detection column 154 will squeeze the wall and deform it. At the moment of pulling out the limit block 116, the mounting plate 5 can obtain a certain initial kinetic energy, so that the mounting plate 5, the detection head 9 and the detection column 154 can act on the wall with a certain pressure, so that the wall can be tested at a constant pressure, making the detection result more accurate.

[0041] like Figure 1 and Figure 5 As shown, a construction engineering wall quality detector provided by the present invention, in order to ensure that the two limit blocks 116 are pulled out of the second slot 119 at the same time, so that the fixed tube 2 is synchronously stressed, in this embodiment, a release component 7 is also included, the release component 7 includes two L-shaped rods 71, the two L-shaped rods 71 ​​are respectively hinged at both ends of the mounting plate 5, the two L-shaped rods 71 ​​are fixedly connected to the ends of the fixed pressure mechanism 11, and the two L-shaped rods 71 ​​are close to The one end of the fixed pressure mechanism 11 is fixedly connected with a dial plate 72, and a movable groove 73 is opened on the dial plate 72. The pulling column 114 is slidably connected inside the movable groove 73. The length of the movable groove 73 is not less than the distance from the top of the abutment block 111 to the bottom of the fixed tube 2, and the other ends of the two L-shaped rods 71 ​​are hinged with the same pressing plate 74.

[0042] The pressing plate 74 is pressed downward, and the pressing plate 74 drives the two L-shaped rods 71 ​​to rotate. The L-shaped rods 71 ​​drive the shifting plate 72 to rotate. The shifting plate 72 drives the pulling column 114 to move outward, so that the pulling column 114 drives the limiting block 116 to be pulled out of the second slot 119.

[0043] like Figure 3 As shown, a construction engineering wall quality detector provided by the present invention, in order to ensure the air tightness between the shrinking tube 12 and the fixed tube 2, in this embodiment, a sealing ring 19 is embedded on the side of the shrinking tube 12 located inside the fixed tube 2.

[0044] like Figure 2-Figure 4 As shown, a construction engineering wall quality detector provided by the present invention, before the detection head 9 contacts the wall, the fixed cylinder 2 is in an active state, and the fixed cylinder 2 is not adsorbed on the wall. During this process, when the detection personnel loosens their hands, the extended detection column 154 may cause scratches on the wall, thereby damaging the wall. In order to prevent the detection column 154 from contacting the wall in advance, in this embodiment, a limiting mechanism 6 is also included, and the limiting mechanism 6 includes a receiving groove 68 provided inside the detection head 9, and the receiving groove 68 is connected to the installation groove 153. The internal sliding connection of the receiving groove 68 is a limiting clamp 67, and a first compression spring 66 is connected between the limiting clamp 67 and the side wall of the receiving groove 68. A first card slot 69 is provided on the side of the detection column 154, and the storage slot 68 is plugged into the first card slot 69. A connecting rod 64 is fixedly connected to the side of the limit clamp 67, and one end of the connecting rod 64 is fixedly connected to a fixing frame 63. A connecting piece 65 is fixedly connected to the bottom of the mounting plate 5, and the connecting rod 64 is slidably connected to the connecting piece 65. A fixing rod 61 is fixedly connected to the side of the shrinking tube 12, and one end of the fixing rod 61 is fixedly connected to a plug column 62 adapted to the fixing frame 63, and an oblique cut surface is provided on the end of the plug column 62. The distance from the top of the plug column 62 to the top of the fixing frame 63 is not greater than the distance from the end of the detection head 9 to the bottom of the fluid seal 14.

[0045] When the fixed tube 2 is blocked by the abutment block 111, the plug column 62 is inserted into the fixed frame 63, and the beveled surface on the plug column 62 drives the fixed frame 63 and the connecting rod 64 to move. The connecting rod 64 drives the limit clamp 67 to move, and the limit clamp 67 is pulled out of the first slot 69. Under the action of the fourth compression spring 152, the detection column 154 contacts the wall.

[0046] like Figure 1-Figure 3 and Figure 7As shown, a construction engineering wall quality detector provided by the present invention, due to the high hardness of the rubber ring 13, when some tiny depressions appear on the wall, the rubber ring 13 cannot fill the depressions, and the shrink tube 12 may leak from the depressions. In order to make the shrink tube 12 more sealed, in this embodiment, a fluid seal 14 is fixedly connected to the bottom of the rubber ring 13, and the fluid seal 14 is an annular hollow structure. The interior of the fluid seal 14 is filled with a non-Newtonian fluid, and the fluid seal 14 is made of high-strength, wear-resistant and flexible material, such as a thermoplastic polyurethane (TPU) film.

[0047] After the shrink tube 12 is pushed, the fluid seal 14 is squeezed against the wall, and the non-Newtonian fluid automatically fills the depression on the wall, thereby increasing the sealing between the shrink tube 12 and the wall and improving the stability of the device.

[0048] like Figure 7 As shown, a construction engineering wall quality detector provided by the present invention, in this embodiment, a plurality of partitions 20 are arranged inside the fluid seal 14, and the plurality of partitions 20 divide the interior of the fluid seal 14 into a plurality of small cavities, and the non-Newtonian fluid is evenly distributed in the plurality of small cavities, so as to prevent all the non-Newtonian fluid from gathering on one side of the fluid seal 14, so that the fluid seal 14 can quickly fill the depression on the wall, so that the shrink tube 12 has better sealing performance.

[0049] The invention provides a construction engineering wall quality detector, in this embodiment, further comprising an alarm device, which is electrically connected to the air pressure sensor 16. A threshold is set for the air pressure sensor 16, and when the air pressure in the fixed cylinder 2 reaches the threshold and the vacuum pump 3 is turned off, the alarm device is activated, and when the blocking of the fixed cylinder 2 by the constant pressure mechanism 11 is released and the wall is deformed, the value detected by the air pressure sensor 16 will change, and at this time, the alarm device will sound an alarm to remind the inspection personnel.

[0050] Working principle: hold the handle 4 and stick the fluid seal 14 to the wall, start the vacuum pump 3, the vacuum pump 3 extracts the air in the fixed tube 2, under the action of atmospheric pressure, the mounting plate 5 approaches the wall, when the fixed tube 2 is blocked by the abutment block 111, the detection head 9 contacts the wall, the vacuum pump 3 continues to extract air, because the volume between the shrink tube 12 and the fixed tube 2 remains unchanged, the air inside is reduced, resulting in a decrease in the internal pressure, when the pressure reaches the threshold, turn off the vacuum pump 3, and then press the pressing plate 74, the pressing plate 74 drives the L-shaped rod 71 and the dial plate 72 to rotate, the dial plate 72 drives the pull column 114 to move, thereby limiting Block 116 is pulled out from the second card slot 119, and the abutment block 111 no longer blocks the movement of the fixed tube 2. The fixed tube 2 drives the mounting plate 5 and the detection head 9 to move toward the wall. When the wall quality is qualified, the detection head 9 will not move, so that the volume between the shrink tube 12 and the fixed tube 2 remains unchanged, and the pressure therein remains unchanged. When the wall quality is unqualified, the wall is compressed and deformed by the detection head 9, and the detection head 9 approaches the wall, resulting in a decrease in the volume between the shrink tube 12 and the fixed tube 2, thereby increasing the pressure, and the alarm device sounds an alarm. The detection personnel can quickly lock the depression of the wall, that is, the unqualified part of the wall, thereby improving the detection efficiency.

[0051] At the same time, the pressure exerted by the detection column 154 on the wall can be determined by observing the reading on the second display 10, and the strength of the wall at that location can be obtained.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
