Description

Technical Field

[0001] The 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] In water conservancy projects, concrete is widely used and is one of the most commonly used building materials in water conservancy projects. For example, it plays an important role in water conservancy projects such as dams, sluice gates, and hydropower stations. Among them, the carbonization depth of concrete is an important indicator of concrete durability. The traditional detection method is the drilling method, which drills a circular hole at the position to be tested and drips phenolphthalein alcohol test solution into the circular hole. When the dripped phenolphthalein alcohol reagent is still colorless, it indicates that the concrete here has been carbonized. When the phenolphthalein alcohol reagent turns purple, it indicates that the concrete here is not carbonized. The carbonization depth of concrete is detected by measuring the color change boundary. However, manual drilling is time-consuming and labor-intensive, and the drilling is irregular and inconsistent.

[0032] The target area is punched by the 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 driving component to make the multiple grippers hold the concrete rod tightly. The concrete rod is broken and taken out under the continuous loading of the driving component, and the phenolphthalein alcohol solution is sprayed on the inner wall of the hole by the reagent spraying mechanism to observe the color change.

[0033] Furthermore, the driving assembly includes an electric winch 19 fixedly mounted on the slider 14 , a fixed pulley 18 is fixedly provided on the crossbeam 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 seat 17, and the plurality of brackets 26 are arranged at equal intervals along the circumference of the mounting seat 17, one end of a swing arm 27 is hinged on the bracket 26, the other end of the swing arm 27 is fixedly connected to a clamping jaw 28, a fixing ring 30 is fixedly connected to the clamping jaw 28, one end of a steel wire 31 is fixed to the fixing ring 30 on one of the clamping jaws 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.

During the drilling operation, the dust suction component is turned on at the same time, and the dust generated by the drilling is sucked through the dust 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 in sequence 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.

[0040] Furthermore, the dust collection assembly includes a dust collection box 6 fixedly connected to the shell 5, and a dust collector is arranged 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, so as to prevent 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, and 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 rod 21 rotatably connected to the outer wall of the shell 5, and the end of the operating rod 21 away from the shell 5 is connected to an L-shaped spray nozzle 22, and the 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, a slider 14 is slidably sleeved on the column 2, a locking motor 4 is installed on the slider 14, and the output end of the locking motor 4 is connected to a gear, which is meshed with the rack 3.

[0045] The locking motor 4 is provided to drive the gear and the rack 3 to mesh 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 to limit the mounting seat 17, so that the mounting seat 17 moves together with the slider 33, and the concrete rod is broken and removed.

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

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

[0049] Specifically, align the drill bit with the test point, and use the motor 7 to drive the rotating shaft and the drill bit to drill holes in 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, and 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, and 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 taken out;

[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 pulling 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 to the concrete rod more tightly, and at the same time, the jaws 28 are prevented from sliding on the outer wall of the concrete rod. Multiple anti-slip teeth 29 are arranged 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 aim the high-definition camera 23 at 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 aim the high-definition camera 23 at the hole wall sprayed with the phenolphthalein alcohol solution to observe the color change.

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

[0055] Specifically, drop a 1% to 2% phenolphthalein alcohol solution on the edge of the inner wall of the hole to ensure that the test solution is evenly wet 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 the carbonized and uncarbonized concrete. The uncarbonized part usually appears 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 less than 3 measurements and take the average value to obtain a more accurate result. The measurement is accurate to 0.5mm. During the test process, the formation, cleaning and dripping of the hole, etc., should be ensured to avoid affecting the measurement results.

[0056] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
