TECHNICAL FIELD

[0001] The application relates to the technical field of concrete carbonation detection, in particular to a concrete carbonation depth testing device. BACKGROUND

[0002] In building engineering, the carbonation of concrete will affect its durability and mechanical properties, and further affect the structural safety of the building. Accurate detection of the carbonation depth of concrete is crucial for evaluating the health status of the concrete structure.

[0003] The traditional concrete carbonation depth detection method mainly relies on manual drilling of holes with a certain diameter and depth on the concrete, and then using phenolphthalein reagent for color development, and then measuring the carbonation depth with a measuring tool. This method is not only tedious and inefficient, but also greatly affected by human factors, and the detection accuracy is difficult to guarantee. Therefore, it is necessary to develop a high-efficiency, accurate and simple-to-operate concrete carbonation depth detection device. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the efficiency and accuracy of the detection of the carbonation depth of concrete, the application provides a concrete carbonation depth testing device.

[0005] The concrete carbonation depth testing device provided by the application adopts the following technical scheme:

[0006] A concrete carbonation depth testing device comprises a frame body, a drilling mechanism for drilling holes in concrete and developing the side wall of the hole is arranged on the frame body, and a detection assembly for detecting the developed area on the side wall of the hole is arranged on the frame body.

[0007] A mounting plate is slidably arranged on the frame body along the drilling axis;

[0008] A driving member is arranged on the frame body and used for driving the mounting plate to slide;

[0009] A drill bit is rotatably arranged on the mounting plate through a drill rod and used for drilling holes in concrete;

[0010] A rotary motor is arranged on the mounting plate and used for driving the drill bit to rotate;

[0011] A color development assembly is arranged on the mounting plate, and the color development assembly is used for spraying phenolphthalein reagent on the side wall of the hole and developing the carbonation area;

[0012] A dust suction assembly is arranged on the mounting plate and used for sucking dust in the hole.

[0013] By adopting the above technical scheme, the rotating motor drives the drill bit to rotate, and the driving member drives the installation sliding block to slide downward, so as to drill the concrete floor, and the dust suction assembly discharges the materials and dust generated during drilling. When drilling is completed and the drill bit is retracted, the phenolphthalein reagent is sprayed on the side wall of the drill hole through the color development assembly, so as to develop color on the side wall of the drill hole. Finally, the drill bit returns to the original position, and the developed area on the side wall of the drill hole is detected by the detection assembly, so as to finally complete the detection of the carbonation depth of the concrete, and improve the efficiency and accuracy of the detection of the carbonation depth of the concrete.

[0014] Further, the color development assembly comprises:

[0015] A liquid storage tank is arranged on the mounting plate and used for storing the phenolphthalein reagent;

[0016] A liquid discharge pump is arranged on the mounting plate and used for discharging the reagent in the liquid storage tank;

[0017] A spray head is arranged on the drill rod and communicates with the liquid discharge pump through a connecting assembly.

[0018] By adopting the above technical scheme, the liquid discharge pump pumps out the reagent in the liquid storage tank, and finally discharges the reagent into the spray head through the connecting assembly. The spray head rotates with the drill rod and sprays the reagent on the side wall of the drill hole, so as to facilitate color development on the side wall of the drill hole.

[0019] Further, the connecting assembly comprises:

[0020] A connecting ring is arranged on the mounting plate and abuts against the drill rod in rotation. An annular groove is formed in the side of the connecting ring close to the drill rod. An annular discharge channel is formed in the drill rod and communicates with the inside of the annular groove. The annular discharge channel communicates with the spray head.

[0021] A connecting pipe is arranged on the discharge end of the liquid discharge pump and communicates with the inside of the annular groove.

[0022] By adopting the above technical scheme, the liquid discharge pump pumps the reagent in the liquid storage tank into the connecting pipe, so as to pump the reagent into the annular groove. The annular groove and the annular discharge channel are in rotation communication, so as to discharge the reagent pumped out by the liquid discharge pump into the spray head for spraying.

[0023] Further, the dust suction assembly comprises:

[0026] An air extractor is arranged on the mounting plate and used to provide suction to the material extraction pipe.

[0027] By adopting the above technical scheme, when the air extractor is started, the material extraction pipe extracts the material and dust in the dust removal space, thereby reducing the content of the material and dust in the drilling hole due to drilling, and facilitating subsequent spraying of the reagent on the sidewall of the drilling hole for color development.

[0029] By adopting the above technical scheme, when the drill bit drills a hole, the first telescopic member is shortened to close the placement groove, thereby reducing the probability of dust entering the placement groove, and when the drilling is completed, the first telescopic member is elongated to open the placement groove, thereby facilitating the spray head to spray the reagent on the sidewall of the drilling hole.

[0030] Further, the frame body is provided with a protective cover, the baffle is slidably arranged in the protective cover, and a dust removal space is formed between the protective cover, the baffle and the drill bit before the baffle enters the drilling hole.

[0031] By adopting the above technical scheme, before the baffle enters the drilling hole, the protective cover replaces the sidewall of the drilling hole to form a dust removal space, thereby facilitating the timely extraction of the material and dust generated during drilling.

[0032] Further, the detection assembly comprises:

[0033] A sliding block is slidably arranged on the frame body through the protective cover;

[0034] A camera is arranged on the sliding block and used to collect data of the color development area in the drilling hole;

[0035] An illuminating lamp is arranged on the sliding block and used to illuminate the drilling hole;

[0036] A second telescopic member is arranged on the frame body and used to drive the sliding block to slide.

[0037] By adopting the above technical scheme, when the drill bit moves out of the drilling hole, the second telescopic member drives the sliding block to slide, thereby moving the camera and the illuminating lamp directly above the drilling hole, thereby facilitating the illuminating lamp to illuminate the drilling hole and the camera to collect data of the color development area in the drilling hole.

[0038] Further, the protective cover side wall is provided with an installation hole through which the sliding block passes, and the sliding block is provided with a sealing block used for sealing the installation hole on one side close to the middle of the protective cover.

[0039] By adopting the above technical scheme, the installation hole is sealed by the sealing block when the drill bit drills a hole, so as to prevent dust from entering the installation hole and reduce the pollution probability of the camera and the illuminating lamp.

[0040] Further, the frame body is provided with a control terminal used for displaying the data collected by the camera after analysis.

[0041] By adopting the above technical scheme, the control terminal is connected with the camera, so as to analyze and calculate the data collected by the camera, and finally display the calculation result.

[0042] In summary, the present application has at least one of the following beneficial technical effects:

[0043] By rotating the drill bit through the rotating motor and driving the installation sliding block to slide downward through the driving member, the concrete floor is drilled, and the material and dust generated during drilling are discharged through the dust suction assembly. When the drilling is completed and the drill bit is retracted, the phenolphthalein reagent is sprayed on the side wall of the drill hole through the spray head rotating with the drill rod, so as to develop color on the side wall of the drill hole. Finally, the drill bit returns to the original position, and the developed area on the side wall of the drill hole is detected through the detection assembly, so as to finally complete the detection of the carbonation depth of the concrete, improve the efficiency and accuracy of the detection of the carbonation depth of the concrete.
