Description

Technical Field

[0001] The present invention belongs to the technical field of concrete carbonization detection, and in particular relates to a concrete carbonization depth detection device and a use method. Background Art

[0002] Concrete is widely used in water conservancy projects and is one of the most commonly used building materials in these projects. For example, it plays a vital role in water conservancy projects such as dams, sluice gates, and hydropower stations. The carbonation depth of concrete is a key indicator of concrete durability. Traditionally, the drilling method involves drilling a circular hole at the test location and dripping a phenolphthalein alcohol test solution into the hole. If the phenolphthalein alcohol test solution remains colorless, it indicates that the concrete at this location has been carbonized. If the phenolphthalein alcohol test solution turns purple, it indicates that the concrete at this location has not been carbonized. The carbonation depth of the concrete is then measured by measuring the color change boundary. However, manual drilling is time-consuming and labor-intensive, and the holes are irregular and inconsistent. Furthermore, it inevitably squeezes the concrete material, causing the boundary between the carbonized and uncarbonized areas to shift, affecting the accuracy of the experimental test.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 6 As shown, the present invention provides a concrete carbonation depth detection device, including a frame, a slider 2 14 is slidably provided on the frame, one side of the slider 2 14 is horizontally fixedly connected to a guide rail 11, a punching mechanism and a reagent spraying mechanism are slidably provided on the guide rail 11, the other end of the slider 2 14 is fixedly provided with a crossbeam 15, and a grabbing mechanism for taking out concrete rods is slidably provided on the crossbeam; the grabbing mechanism includes a mounting seat 17 slidably limited on the crossbeam 15, and a plurality of grippers are circumferentially provided on the outer wall of the mounting seat 17, one end of a steel wire 31 is fixedly connected to one gripper, and the other end of the steel wire 31 passes through the remaining grippers in sequence and is connected to one end of a slider 33, the slider 33 is slidably provided on the mounting seat 17, and the other end of the slider 33 is transmission-coordinated with a drive assembly.

[0032] The target area is punched through the provided punching mechanism, and the floating dust in the hole is removed at the same time. Multiple grippers are synchronously inserted between the concrete rod and the hole wall. The steel wire 31 is pulled by the provided driving component to make the multiple grippers hold the concrete rod tightly. The concrete rod is broken and removed under the continuous loading of the driving component, and the phenolphthalein alcohol solution is sprayed on the inner wall of the hole through the provided reagent spraying mechanism to observe the color change.

[0033] Furthermore, the drive assembly includes an electric winch 19 fixedly mounted on the slider 14 , a fixed pulley 18 is fixedly provided on the beam 15 , and one end of the steel wire rope on the electric winch 19 passes through the fixed pulley 18 and is fixedly connected to the slider 33 .

[0034] The electric winch 19 continuously reels in the wire rope, which pulls the slider 33 . The fixed pulley 18 is provided to determine the reeling path of the wire rope and limit the force direction of the slider 33 , thereby achieving smooth movement of the slider 33 on the mounting seat 17 .

[0035] Furthermore, the gripper includes a plurality of brackets 26 fixedly connected to the outer wall of the mounting base 17, and the plurality of brackets 26 are arranged at equal intervals along the circumference of the mounting base 17. One end of a swing arm 27 is hinged on the bracket 26, and the other end of the swing arm 27 is fixedly connected to a clamping jaw 28, and a fixing ring 30 is fixedly connected to the clamping jaw 28. One end of the steel wire 31 is fixed to the fixing ring 30 on one clamping jaw 28, and the other end of the steel wire 31 passes through the fixing rings 30 on the remaining clamping jaws 28 in turn and is fixedly connected to the slider 33.

[0036] The electric winch 19 continuously reels in the wire rope, and the wire rope pulls the slider 33, and the slider 33 pulls the wire line 31. The multiple jaws 28 drive the swing arm 27 to rotate on the bracket 26 under the pull of the wire line 31. At the same time, the multiple jaws 28 are tightly clamped on the concrete rod. As the electric winch 19 continuously reels and loads, the multiple jaws 28 are tied tighter to the concrete rod, and at the same time, the jaws 28 are prevented from sliding on the outer wall of the concrete rod. A plurality of anti-slip teeth 29 are provided on the jaws 28. As the loading and pulling are continuously carried out, the concrete rod is broken and taken out.

[0037] Furthermore, the punching mechanism includes a slider 12 slidably connected to the guide rail 11, a handle 13 is provided at the top of the slider 12, and the bottom end of the slider 12 is rotatably connected to the shell 5.

The other end of the rotating shaft extends out of the shell 5 and is fixedly installed with a drill bit. A dust cover 9 is provided on the rotating shaft, and a plurality of dust heads 10 are provided on the inner wall of the dust cover 9. The plurality of dust heads 10 are all connected to a dust collection assembly through a conduit.

[0038] The motor 7 drives the rotating shaft and the drill bit to drill holes in the target area. During the drilling operation, the dust collection component is turned on at the same time, and the dust generated by the drilling is sucked through the dust collection hood 9. When drilling, the operator can hold the handle 13 and push it closer to the target area. When the reagent spraying mechanism needs to be aimed at the hole, it is only necessary to rotate the shell 5 to adjust the direction. After adjusting the direction, it is locked with a fastening bolt to prevent left and right swinging during the drilling operation.

[0039] The drill bit includes a drill bit 35, an inner cylindrical drill bit 34 and an outer cylindrical drill bit 8 which are coaxially arranged from the inside to the bottom. A gap is set between the inner cylindrical drill bit 34 and the outer cylindrical drill bit 8 to reduce the resistance of drilling. The drill bit 35 is used for positioning to prevent the drill bit from slipping sideways on the concrete surface during drilling.

[0040] Furthermore, the dust collection assembly includes a dust collection box 6 fixedly connected to the shell 5, and a dust collector is provided in the dust collection box 6. The dust collector is connected to the dust collection head 10 through a conduit.

[0041] The vacuum cleaner is provided to provide suction to generate negative pressure in the dust hood 9, and the dust enters the dust box 6 through the dust head 10, preventing the punching dust from spreading outward and affecting the operation. It should be noted that the dust hood 9 is slidably sleeved on the protective shell, and the protective shell is integrally formed with the shell 5. The protective shell cover is arranged on the rotating shaft connected to the output shaft of the motor 7.

[0042] Furthermore, the reagent spraying mechanism includes an operating lever 21 rotatably connected to the outer wall of the shell 5, and the end of the operating lever 21 away from the shell 5 is connected to an L-shaped liquid spray nozzle 22, and the liquid spray nozzle 22 is connected to the water outlet end of the water pump 25 through a hose, and the water inlet end of the water pump 25 is connected to the reagent box 24, and the water pump 25 and the reagent box 24 are both arranged in the shell 5.

[0043] The phenolphthalein alcohol solution contained in the reagent box 24 is sprayed onto the inner wall of the hole through the spray nozzle 22 by the water pump 25.

[0044] Furthermore, the frame includes a base 1, the top of the base 1 is fixedly connected to a column 2, the column 2 is fixedly connected to a rack 3 in the vertical direction, the slider 14 is slidably mounted on the column 2, the slider 14 is installed with a locking motor 4, the output end of the locking motor 4 is connected to a gear, and the gear is meshed with the rack 3.

[0045] The locking motor 4 is provided to drive the gear and the rack 3 to engage and transmit, thereby driving the slider 2 14 to slide on the column 2, thereby achieving height adjustment, which is convenient for punching test and observing color change.

[0046] Furthermore, in order to reduce friction and ensure the smooth movement of the mounting seat 17, a guide groove 16 is opened on the beam 15, and a plurality of pulleys 20 are fixedly connected to the top of the mounting seat 17. The pulleys 20 are slidably limited in the guide groove 16. A clamping bolt 36 is threadedly connected to the beam 15. The clamping bolt 36 is used to limit and fix the mounting seat 17 on the beam 15. Specifically, in order to achieve the clamping force of the clamping jaws 28 on the concrete rod, it is necessary to use the clamping bolt 36 to fix the mounting seat 17 on the beam 15 in the initial stage. When a certain clamping force is reached, the clamping bolt 36 is released from the mounting seat 17, so that the mounting seat 17 moves together with the slider 33, and the concrete rod is pulled off and removed.

[0047] The present invention provides a method for using a device for detecting the carbonization depth of concrete, comprising the following steps:

[0048] Use the punching mechanism to punch holes in the target detection area, and use the dust suction component to remove dust on the hole wall;

[0049] Specifically, the drill bit is aligned with the test point, and the motor 7 drives the rotating shaft and the drill bit to drill the target area. During the drilling operation, the vacuum cleaner is provided to provide suction to generate negative pressure in the dust hood 9, and the dust enters the dust box 6 through the dust head 10 to prevent the drilling dust from spreading outward.

[0050] Insert the clamping jaws 28 between the concrete rod and the inner wall of the hole, start the electric winch 19 to pull the slider 33, the slider 33 slides on the mounting seat 17 and pulls the steel wire 31. The multiple clamping jaws 28 hold the concrete rod tightly under the pull of the steel wire 31. At this time, the clamping bolt 36 is separated from the mounting seat 17. The mounting seat 17 moves along the guide groove 16 under the pull of the electric winch 19 until the concrete rod is broken and removed;

[0051] Specifically, the drill bit is taken out, and the wire rope is continuously reeled in by the electric winch 19. The wire rope pulls the slider 33, and the slider 33 pulls the wire 31. The multiple jaws 28 drive the swing arm 27 to rotate on the bracket 26 under the pull of the wire 31. At the same time, the multiple jaws 28 are tightly clamped on the concrete rod. As the electric winch 19 continuously reels and loads, the multiple jaws 28 are tied tighter to the concrete rod, and at the same time, the jaws 28 are prevented from sliding on the outer wall of the concrete rod. A plurality of anti-slip teeth 29 are provided on the jaws 28. As the loading and pulling are continuously carried out, the concrete rod is broken and taken out.

[0052] Start the water pump 25 and spray the phenolphthalein alcohol solution onto the inner wall of the hole through the liquid spray nozzle 22, rotate the operating lever 21 to make the high-definition camera 23 focus on the hole wall sprayed with the phenolphthalein alcohol solution, and observe the color change;

[0053] Specifically, the phenolphthalein alcohol solution contained in the reagent box 24 is sprayed onto the inner wall of the hole through the spray nozzle 22 by the water pump 25, and then the operating lever 21 is rotated to make the high-definition camera 23 aim at the hole wall sprayed with the phenolphthalein alcohol solution to observe the color change.

[0054] Measure the carbonation depth by using a measuring tool to measure the vertical distance from the interface between carbonized and uncarbonized concrete to the concrete surface.

[0055] Specifically, drip a 1% to 2% phenolphthalein alcohol solution onto the edge of the inner wall of the hole, ensuring that the test solution is evenly wetted on the surface but does not flow. Observe the interaction between the phenolphthalein test solution and the concrete, paying special attention to the boundary between carbonized and uncarbonized concrete. The uncarbonized portion will typically appear pink. When the boundary between the carbonized and uncarbonized concrete is clear, use a measuring tool to measure the vertical distance from the interface between the carbonized and uncarbonized concrete to the concrete surface. Perform no fewer than three measurements and average them for a more accurate result. Measurements should be accurate to 0.5 mm. During the testing process, ensure that the hole formation, cleaning, and addition of the phenolphthalein solution are performed in accordance with the relevant procedures to avoid affecting the measurement results.
