Description

Technical Field

[0001] The utility model belongs to the technical field of coating thickness detection, and relates to a device for quickly detecting the thickness of polymer inorganic waterproof coating. Background Technique

[0002] Polymer inorganic waterproof coatings, especially polymer cement waterproof coatings, are waterproof materials widely used in the construction field. During the construction of waterproof coatings, the thickness of the waterproof coating has a direct impact on the building waterproof performance. Therefore, the thickness detection of waterproof coatings is a necessary item in building quality inspection.

[0003] The building engineering supervision waterproof coating thickness detector disclosed in Chinese Patent CN215725824U includes a detection seat, a pressing seat, a rear cover, an installation cavity, a sliding block, and a plug pin. A perforation for the free passage of the plug pin and penetrating the installation cavity is provided on the pressing seat. The sliding block is driven by a driving module to move up and down. A display device and a displacement sensor are provided on the rear cover, and an induction block cooperating with the displacement sensor is provided on the sliding block.

[0004] The above-mentioned existing coating thickness detector has the following problems when in use: when the above-mentioned detector is in use, after the plug pin moves downward and inserts into the coating layer, it will contact the concrete layer, resulting in the bottom end of the plug pin penetrating through the waterproof coating layer and further piercing into the concrete ground. In this way, not only the measurement accuracy is affected, but also the bottom end of the plug pin is damaged, resulting in the scrapping of the instrument. A high-precision waterproof coating thickness quick detection device disclosed in Chinese Patent CN221055691U, by setting an elastic member, when the metal needle touches the concrete ground for an instant, the thrust of the elastic member on the rack is less than the resistance brought by the concrete ground to the probe assembly. Therefore, the whole probe assembly stops moving downward. Although it can protect the metal needle; however, it is necessary for the detector to observe that the rack slides downward in the driving section and immediately stop turning the handle to obtain accurate detection data. If not stopped immediately, the rack continues to move downward and compress the elastic member, and the metal needle will also be under pressure, resulting in damage to the tip of the metal needle and affecting the measurement data at the same time. Therefore, it consumes a lot of manpower and the work efficiency is low.

[0005] To solve the above problems, the utility model proposes a device for quickly detecting the thickness of polymer inorganic waterproof coating. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0025] Embodiment 1: As Figures 1-4 shown, the technical solution adopted by the present utility model is as follows: A thickness quick inspection device for polymer inorganic waterproof coating, including a detection cylinder 1, and two fixed disks 2 are slidably arranged inside the detection cylinder 1.

[0026] Specifically, limiting sliding grooves 9 are provided on both the front and rear sides of the inner wall of the detection cylinder 1; limiting plates 10 are fixedly connected to both the front and rear sides of the two fixed plates 2; the limiting plates 10 are correspondingly slidably installed inside the limiting sliding grooves 9; the movement of the two fixed plates 2 is limited, making the detection data more accurate.

[0027] A spring 3 is fixedly connected between the two fixed plates 2; an installation frame 4 is fixedly installed on the upper end surface of the detection cylinder 1; an electric telescopic rod 5 is fixedly connected inside the installation frame 4; the telescopic end of the electric telescopic rod 5 slidably penetrates into the detection cylinder 1, and the telescopic end of the electric telescopic rod 5 is fixedly connected to the upper fixed plate 2; a ranging component is arranged on the upper end surface of the upper fixed plate 2.

[0028] The ranging component includes an induction block 11; the induction block 11 is fixedly installed on the upper end surface of the upper fixed plate 2; a displacement sensor 12 is fixedly connected at a position corresponding to the induction block 11 at the inner top of the detection cylinder 1; a display 13 is fixedly installed on the front side of the upper end surface of the detection cylinder 1.

[0029] A probe 6 is fixedly connected to the center position of the lower end surface of the lower fixed plate 2.

[0030] A base 7 is arranged at the bottom end of the detection cylinder 1. External threads are provided on the outer side of the bottom end of the detection cylinder 1; internal threads are provided on the inner side of the top end of the base 7; the base 7 is threadedly connected to the bottom end of the detection cylinder 1.

[0031] A through hole is provided at the center position of the base 7; a rubber block 8 is fixedly connected inside the through hole; a tapered through hole 15 is provided on the rubber block 8; the tapered through hole 15 corresponds to the probe 6.

[0032] A control component for controlling the electric telescopic rod 5 to stop is arranged on the fixed plate 2.

[0033] The control component includes four connecting blocks 16; the four connecting blocks 16 are respectively fixedly connected to the left and right sides of the two fixed plates 2; connecting rods 17 are rotatably installed on the connecting blocks 16; the upper and lower corresponding two connecting rods 17 are rotatably connected through a U-shaped connecting plate 18; rectangular grooves 19 are provided on the inner wall of the detection cylinder 1 at positions corresponding to the two U-shaped connecting plates 18; first pressure sensors 20 are fixedly connected inside the rectangular grooves 19.

[0034] A controller is arranged on the detection cylinder 1, which is not shown in the figure. The controller is electrically connected to the first pressure sensor 20. When the first pressure sensor 20 is subjected to pressure, it will immediately transmit an electrical signal to the controller, causing the controller to control the electric telescopic rod 5 to stop operating.

[0035] The lower end face of the base 7 is provided with an annular groove 14. If the wall surface is uneven, the tightness between the base 7 and the wall surface will be affected. By setting the annular groove 14, the contact area between the bottom surface of the base 7 and the wall surface is reduced, thereby reducing the influence of the wall surface flatness on the tightness between the base 7 and the wall surface.

[0036] Working principle:

[0037] During use, the detection cylinder 1 is vertically placed in the area where the thickness of the coating needs to be detected; the bottom surface of the base 7 is brought into contact with the coating layer, the electric telescopic rod 5 is started, and the telescopic end of the electric telescopic rod 5 extends to drive the two fixing plates 2 and the spring 3 to move downward synchronously, thereby driving the probe 6 to move downward; the probe 6 moves downward and inserts into the coating layer; the resistance of the coating layer to the bottom end of the probe 6 is less than the elastic force of the spring 3, so that the spring 3 will not contract before the bottom end of the probe 6 touches the concrete layer; when the bottom end of the probe 6 passes through the coating layer and reaches the concrete layer, at this time, the resistance of the concrete to the bottom end of the probe 6 is greater than the elastic force of the spring 3, and the telescopic end of the electric telescopic rod 5 continues to move downward to cause the spring 3 to deform and contract, and the contraction of the spring 3 causes the two fixing plates 2 to move closer to each other, thereby causing the connecting rod 17 to rotate and drive the two U-shaped connecting plates 18 to move away from each other; the two U-shaped connecting plates 18 move away from each other and come into contact with the corresponding first pressure sensor 20. After the first pressure sensor 20 receives the pressure, it immediately sends an electrical signal to the controller, and the controller controls the electric telescopic rod 5 to stop to avoid continuously applying pressure to the probe 6 and causing damage to the probe 6.

[0038] During the downward movement of the upper fixing plate 2, the induction block 11 is driven to move downward synchronously. After being inserted in place, the displacement sensor 12 receives the displacement signal of the induction block 11 and feeds the displacement signal back to the external controller, and then the external controller sends the data to the display 13, and the display 13 displays the displacement amount, so that the thickness of the waterproof coating layer can be detected.

[0039] It should be noted that before the bottom end of the probe 6 reaches the concrete layer, the U-shaped connecting plate 18 has come into contact with the first pressure sensor 20 but has not applied pressure to the first pressure sensor 20. Therefore, when the upper fixing plate 2 and the lower fixing plate 2 move relatively, the U-shaped connecting plate 18 immediately applies pressure to the first pressure sensor 20. After the first pressure sensor 20 receives the pressure, it immediately sends an electrical signal to the controller, and the controller controls the electric telescopic rod 5 to stop. Therefore, the downward movement distance of the upper fixing plate 2 is basically the same as the downward movement distance of the probe 6, ensuring the accuracy of the waterproof coating thickness detection.

[0040] During the movement of the probe 6, it needs to pass through the tapered through hole 15, so that the rubber block 8 wipes the outside of the probe 6 and wipes off the waterproof coating adhered to the probe 6.

[0041] Embodiment 2: As Figures 5-6 shown, the difference between this embodiment and Embodiment 1 lies in: the control component is different. The control component of this embodiment includes an abutting rod 21; the abutting rod 21 is fixedly connected to the center position of the upper end face of the lower fixed disk 2; a spring 3 is sleeved outside the abutting rod 21; an installation groove is opened at the position corresponding to the abutting rod 21 on the lower end face of the upper fixed disk 2; a second pressure sensor 22 is fixedly installed inside the installation groove; the second pressure sensor 22 is electrically connected to the controller; the top end of the abutting rod 21 is close to the second pressure sensor 22.

[0042] Limit rods 23 are fixedly connected to both the left and right sides of the upper end face of the lower fixed disk 2; the top ends of the limit rods 23 all slide through the upper fixed disk 2.

[0043] Working principle:

[0044] When in use, when the bottom end of the probe 6 passes through the coating layer and reaches the concrete layer, at this time, the resistance of the concrete to the bottom end of the probe 6 is greater than the elastic force of the spring 3, and the telescopic end of the electric telescopic rod 5 continues to move downward, causing the spring 3 to deform and then contract. The contraction of the spring 3 causes the two fixed disks 2 to move closer to each other, making the top end of the abutting rod 21 come into contact with the second pressure sensor 22. The second pressure sensor 22 immediately sends an electrical signal to the controller, and the controller controls the electric telescopic rod 5 to stop, avoiding damaging the probe 6 by continuously applying pressure to the probe 6; by providing two limit rods 23, the relative movement of the two fixed disks 2 is made more stable. Other working processes are the same as those in Embodiment 1 and will not be elaborated here.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
