Description

Technical Field

[0001] The invention relates to the technical field of concrete detection equipment, and in particular to a combined detection device for concrete carbonization depth. Background Art

[0002] Carbonation of concrete is a kind of chemical corrosion suffered by concrete. The process in which CO2 in the air penetrates into the concrete and reacts chemically with its alkaline substances to form carbonates and water, which reduces the strength of concrete is called concrete carbonation, also known as neutralization. When testing the carbonation depth, use appropriate tools to form holes on the surface of the test area. The depth of the hole is approximately equal to the thickness of the protective layer. Sprinkle a 1% phenolphthalein alcohol solution on the edge of the hole wall, and then use a steel ruler to measure the representative junction from the concrete surface to the deep without discoloration. This depth is the carbonation depth value of the concrete.

[0003] After searching the patent number CN112113489B, a concrete carbonization depth detection device is disclosed, including a base plate, a column is arranged on one side edge of the base plate perpendicular to the base plate, a first rotating rod is arranged on the end of the column away from the base plate, a first rotating shaft is fixedly arranged on one end of the first rotating rod and is penetrated and rotatably connected to the column, a first driving member is arranged on the column, a second rotating rod is arranged on the end of the first rotating rod away from the column, a second rotating shaft is fixedly arranged on one end of the second rotating rod and is penetrated and rotatably connected to the first rotating rod, a second driving member is arranged on the first rotating rod, an electric cylinder is fixedly arranged on the end of the second rotating rod away from the second rotating shaft, the driving end of the electric cylinder is penetrated and slidably connected to the second rotating rod, and a steel ruler is fixedly arranged on the driving end of the electric cylinder, so that the first rotating rod and the second rotating rod can automatically drive the steel ruler to move to the position of each measuring point.

[0004] Compared with the prior art, the patent with patent number CN112113489B adopts a combination of a turbine and a worm respectively in the first driving member and the second driving member. The turbine and worm transmission has a self-locking function and can automatically lock the position after the motor stops without the need for an additional fixed structure. This ensures the stability of the first rotating rod and the second rotating rod after moving to the specified position, thereby improving the accuracy of the measurement.

[0005] However, the above scheme includes multiple motors, turbines, worms, screws and other precision parts in the device. The complex mechanical structure not only increases the manufacturing cost, but also increases the difficulty of subsequent maintenance and troubleshooting. Precision parts such as turbines and worms are prone to wear after long-term use or under high-load conditions, which increases maintenance costs. Although the turbine and worm transmission has a self-locking function, the transmission from the first rotating rod to the second rotating rod may cause cumulative errors due to manufacturing errors, affecting the accuracy of the steel ruler. Therefore, a combined detection device for concrete carbonization depth is proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that the accuracy of steel ruler measurement when measuring the carbonation depth of concrete is affected by the slope, and to ensure the persuasiveness of subsequent data after measurement. Therefore, a combined detection device for the carbonation depth of concrete is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A combined detection device for the carbonation depth of concrete, comprising a box body, the box body is slidably connected to a sliding column, a rack is arranged on the surface of the sliding column, a gear is meshedly connected to the rack, a connecting column is fixedly connected to one side of the gear, a ratchet is arranged on the side of the connecting column, a handle is rotatably connected to one end of the ratchet, a bottom column is arranged at the bottom of the handle, a second pawl which is always attached to the surface of the ratchet is arranged on one side of the bottom column, and a clamping plate is arranged on the side of the second pawl;

[0009] A rotating ball is provided on one side of the card plate close to the sliding column below, and the rotating ball is rotatably connected to a base. A protective column is provided on one end of the base close to the box body above, and the protective column is rotatably connected to a rotator. A worm is fixedly connected to the rotator below, and the worm is meshingly connected to a worm wheel. The worm wheel is fixedly connected to a cylindrical block, and the cylindrical block is rotatably connected to a second rotating shaft. A first rotating shaft is provided on one side of the second rotating shaft.

[0010] The above technical solution further includes:

[0011] A slider is arranged above the first rotating shaft, the slider is slidably connected to a sliding plate, a controller is arranged above the slider, a compression plate is fixedly connected below the controller, a first pawl is arranged on one side of the litigation handle, and the device is also equipped with automatic resetting mechanisms such as a resetting spring, so that it can quickly return to the initial state after the detection is completed, so as to facilitate rapid movement to the next detection point for operation, thereby further improving work efficiency and user experience.

[0012] One side of the bottom column is fixedly connected with a box body, the side of the ratchet is rotatably connected with a connecting column, the side of the connecting column is rotatably connected with a clamping plate, and the connecting column is rotatably connected to the bottom column.

[0013] An anti-skid shock-absorbing pad is arranged under the base. Since the moving height of the sliding column is much greater than the height of the pulley, it ensures that the box remains stable during the entire detection process and will not be displaced due to external factors, thereby greatly improving the accuracy and safety of the detection.

[0014] A fixing column is slidably connected to the top of the box body, a pull rod is fixedly connected to the fixing column, and a sliding motor is arranged on the top of the box body.

This integrated design not only simplifies the structure of the equipment, but also makes the operation more convenient and efficient. The user only needs to perform simple control operations to complete the entire process from mobile positioning, drilling sampling, dust cleaning to carbonization depth detection.

[0016] A pulley is fixedly connected below the box.

[0017] An air pump is arranged below the box body, and a storage box is arranged on one side of the box body, so as to facilitate carrying necessary articles such as phenolphthalein solution.

In addition, since the moving height of the sliding column is much greater than the height of the pulley, it ensures that the box remains stable during the entire detection process and will not be displaced due to external factors, thereby greatly improving the accuracy and safety of the detection.

[0022] 2. This device integrates a high-precision positioning and adjustment system, which drives the transmission of the worm and the worm wheel by rotating the rotator, and then drives the movement of the first rotating shaft and the second rotating shaft, thereby realizing precise vertical and horizontal adjustment of the drill bit. This design not only simplifies the cumbersome positioning steps in the traditional detection process, but also greatly improves the accuracy and flexibility of positioning. Users can easily adjust the position of the drill bit according to their needs to ensure that each drilling can be accurately aimed at the target area, thereby improving the detection efficiency and the reliability of the results.

[0023] 3. The combined detection device for concrete carbonization depth of the present invention integrates multiple functional modules into one, including a drill rotation system driven by a sliding motor, a dust cleaning system driven by an air pump, and the entire workflow controlled by a controller. This integrated design not only simplifies the structure of the equipment, but also makes the operation more convenient and efficient. Users only need to perform simple control operations to complete the entire process from mobile positioning, drilling sampling, dust cleaning to carbonization depth detection.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] like Figure 1-Figure 6As shown, a combined detection device for concrete carbonation depth proposed by the present invention comprises a box body 1, wherein the box body 1 is slidably connected to a sliding column 19, a rack 18 is arranged on the surface of the sliding column 19, the rack 18 is meshingly connected to a gear 17, a connecting column 14 is fixedly connected to one side of the gear 17, a ratchet 12 is arranged on the side of the connecting column 14, a handle 10 is rotatably connected to one end of the ratchet 12, a bottom column 15 is arranged at the bottom of the handle 10, a second pawl 16 which is always attached to the surface of the ratchet 12 is arranged on one side of the bottom column 15, and a clamping plate 13 is arranged on the side of the second pawl 16;

[0034] A rotating ball 20 is provided on one side below the card plate 13 near the sliding column 19, and the rotating ball 20 is rotatably connected to a base 21. A protective column 5 is provided on one end above the base 21 near the box body 1, and the protective column 5 is rotatably connected to a rotator 6. A worm 22 is fixedly connected below the rotator 6, and the worm 22 is meshingly connected to a worm wheel 23. The worm wheel 23 is fixedly connected to a cylindrical block 28, and the cylindrical block 28 is rotatably connected to a second rotating shaft 27. A first rotating shaft 26 is provided on one side of the second rotating shaft 27.

[0035] The working principle of the combined detection device for the carbonation depth of concrete proposed by the present invention is that when detecting the carbonation depth of concrete, the device is first moved to the position where the detection is required by pulling the pull rod 3. Then, the handle 10 is rotated to make the first pawl 11 close to the surface of the ratchet 12, thereby driving the ratchet 12 to rotate unidirectionally. The rotation of the ratchet 12 will drive the connecting column 14 and the gear 17 connected thereto to rotate. Since the gear 17 is engaged with the rack 18, and the rack 18 is fixed on the sliding column 19, the sliding column 19 will move downward accordingly. During the downward movement of the sliding column 19, the base 21 at its bottom will gradually fit the ground. If the ground is uneven, the base 21 will ensure that it fits tightly to the inclined or uneven ground through the flexible rotation of the rotating ball 20, thereby increasing the stability of the device. Since the moving height of the sliding column 19 is much greater than the height of the pulley 7, the box 1 will not slide during the detection process, ensuring the stability of the detection. When the box 1 is fixed, the spring inside the compression plate 9 can be started to compress by controlling the controller 8 inside the box 1, and the air pump 24 starts to work at the same time to push the lower parts to move downward. Under the control of the controller 8, the sliding motor 4 moves downward inside the box 1 until the drill bit reaches the ground position to be drilled. At this time, the sliding motor 4 is started to drive the drill bit to rotate and drill the ground. If the position of the drill bit needs to be adjusted, the rotator 6 can be rotated to drive the worm 22 to drive the worm wheel 23 and the cylindrical block 28 to rotate. The rotation of the cylindrical block 28 will further drive the first rotating shaft 26 and the second rotating shaft 27 to move, so that the vertical or horizontal movement of the drill bit is achieved through the sliding of the slider 30 on the sliding plate 29, ensuring the accuracy of positioning. After drilling, the sliding motor 4 is controlled by the controller 8 to rotate in the opposite direction to make the drill bit rise and leave the hole.

[0036] Embodiment 2

[0037] like Figure 1-Figure 6 As shown, based on the first embodiment, a slider 30 is provided above the first rotating shaft 26, the slider 30 is slidably connected to the sliding plate 29, a controller 8 is provided above the slider 30, a compression plate 9 is fixedly connected below the controller 8, and a first pawl 11 is provided on one side of the litigation handle 10.

[0038] One side of the bottom column 15 is fixedly connected to the box body 1 , the ratchet 12 is rotatably connected to the connecting column 14 on the side, the connecting column 14 is rotatably connected to the clamping plate 13 on the side, and the connecting column 14 is rotatably connected to the bottom column 15 .

[0039] An anti-skid shock-absorbing pad is arranged below the base 21 .

[0040] A fixed column 2 is slidably connected to the top of the box body 1 , a pull rod 3 is fixedly connected to the fixed column 2 , and a sliding motor 4 is arranged on the top of the box body 1 .

[0041] A worm 22 is fixedly connected to one side of the box body 1, a sliding motor 4 is slidably connected to the top of the box body 1, the sliding motor 4 is fixedly connected to a stabilizing block 31 drill fixing device, a drill bit is arranged below the stabilizing block 31 drill fixing device, and a compression plate 9 is fixedly connected to one side of the stabilizing block 31 drill fixing device.

[0042] A pulley 7 is fixedly connected to the bottom of the box body 1.

[0043] An air pump 24 is arranged below the box body 1 , and a storage box is arranged on one side of the box body 1 .

[0044] A measuring ruler 25 is provided on one side of the box body 1 .

[0045] A compressible spring is arranged inside the compression plate 9 .

[0046] The working principle of the combined detection device for the carbonation depth of concrete proposed by the present invention is that for the dust inside the hole, the air pump 22 on the side of the box 1 can be connected to the pipe, and the airflow generated by the air pump 24 can be used to blow away the dust inside the hole. The output end of the air pump 24 is connected to the air pump body, and the gas is stored inside for purging. Finally, in order to detect the carbonation depth of the concrete, phenolphthalein solution can be dripped into the hole. After the detection is completed, by rotating the handle 10 in the opposite direction, the second pawl 16 and the ratchet 12 cooperate, and the internal reset spring is used to make the sliding column 19 rise back to the initial position. At this time, the pull rod 3 can be pulled again to move the device to other positions to detect the carbonation depth of the concrete.
