Description

Technical Field

[0001] The invention relates to the field of concrete detection, and in particular to a corroded reinforced concrete structure performance detector. Background Art

[0002] The load-bearing column is the supporting core of buildings such as bridges and houses. It is usually made of steel bars as brackets and concrete pouring. The load-bearing columns of bridges and houses are usually composed of columns and pedestals at the bottom. The columns support the bridge deck and the house. The pedestals are located in the water to increase the stability of the columns. The pedestals are immersed in water all year round, and the surface is easily eroded by water flow, exposing the internal steel structure. When the steel structure loses the concrete wrapping and is immersed in water, it will rust. The strength of the rusted steel bars decreases, which will affect the overall stability of the concrete pedestal. It is usually necessary to regularly inspect the underwater pedestal to determine whether there are hidden dangers on the pedestal by observing whether there are cracks, defects, exposed steel bars and other phenomena on its surface. In the existing technology, one is to use underwater robots carrying camera equipment to explore the underwater part of the pedestal, but the water flow in rivers is turbulent, and the underwater robot is easily affected by water flow fluctuations, resulting in unclear shooting. The second is to wear diving equipment to go into the water for inspection. The underwater environment is complex, the human eye has poor observation effect, and human diving will also be affected by the turbulent water flow, and personal safety cannot be guaranteed.

[0003] In addition, the test data obtained by observation alone is limited. It is necessary to collect samples from the surface of concrete and test its density, durability and other properties in order to determine the extent to which the properties of the concrete itself are affected by the current environment. When sampling underwater concrete, the water flow will wash the concrete surface, which may easily cause the samples to be washed away by the water flow during the collection process.

[0020] The limiting assembly includes a limiting column 1001, an elastic member 1002 and a pressure plate 1003; four limiting columns 1001 are slidably connected to the traveling vehicle 1; a pressure plate 1003 is fixedly connected to the top of all limiting columns 1001; an elastic member 1002 is sleeved between the limiting column 1001 and the pressure plate 1003, and the elastic member 1002 is a spring.

[0021] The sampling assembly includes a mounting plate 201, a motor 202, a flat gear 1 203, a toothed belt 204, a grinding roller 205, a flat gear 206 and a collecting box 207; an electric push rod 2 11 is installed in the upper chamber of the mounting box 6; two symmetrically arranged guide rods 65 are installed in the upper chamber of the mounting box 6; the two guide rods 65 are slidably connected to the mounting plate 201; the mounting plate 201 is fixedly connected to the telescopic end of the electric push rod 2 11; the motor 202 is bolted to the mounting plate 201; the motor 20 The output shaft is fixedly connected with a flat gear 1 203; the mounting plate 201 is rotatably connected with a grinding roller 205 through a mounting frame; the grinding roller 205 is fixedly connected with a flat gear 206; the flat gear 1 203 and the flat gear 206 are commonly connected with a toothed belt 204, and the flat gear 1 203 and the flat gear 206 are both meshed with the toothed belt 204; a collecting box 207 is installed at the bottom of the mounting plate 201; an inclined collecting plate is provided at the entrance of the collecting box 207, and the collecting plate is located directly below the grinding roller 205.

[0022] The side of the installation box 6 away from the traveling vehicle 1 is tapered, and the tapered surface can guide the water flow to flow to both sides, thereby reducing the impact force of the water flow.

[0023] The collecting plate at the entrance of the collecting box 207 is made of rubber material, which is conducive to fitting the surface of the pier cap 1111.

[0024] The bottom surface of the limit column 1001 is roughened to increase the friction when in contact with the ground and keep the traveling vehicle 1 stable.

[0025] The top of the connecting rod 5 is provided with a thread, and the bottom is provided with a threaded sleeve, so that a plurality of connecting rods 5 can be combined to extend the overall length, so that the present invention can adapt to different water depths.

[0026] The facing surfaces of the two sealing doors 61 are designed to be interlocked to ensure a sealing and waterproof effect.

[0027] In the prior art, underwater robots are used to inspect the underwater parts of concrete bridge piers, which are easily affected by water flow fluctuations, resulting in unclear photography. In addition, people wear diving equipment to go into the water for inspection. The underwater environment is complex, the human eye has poor observation effect, and human diving is also affected by turbulent water flow, and personal safety cannot be guaranteed. Therefore, the present invention provides a corroded reinforced concrete structure performance detector.

[0028] Taking the detection of the water-facing surface of the bridge pier cap 1111 as an example, the scouring force of the water flow is the largest at this time. Figure 1 As a direction reference, the direction of the installation box 6 is the front side, that is, the water-facing surface of the bridge pier cap 1111, and the direction of the walking vehicle 1 is the rear side. It should be noted that when performing the inspection, the upper surface of the bridge pier cap 1111 needs to be higher than the water surface. When performing the inspection, the user carries the present invention to the bridge pier cap 1111, and the interior of the installation box 6 is divided into two upper and lower chambers by the partition plate 64. The user sets a battery in the upper chamber of the installation box 6 to power the electric part, and then as Figure 3 As shown, the walking vehicle 1 is brought close to the edge of the water-facing surface of the pier cap 1111, the walking vehicle 1 and the installation box 6 are combined at a right angle, and the rear side of the installation box 6 is close to the water-facing surface of the pier cap 1111. In the initial state, the two sealing doors 61 are in a closed state to seal the inside of the installation box 6. Then, the user places a heavy object on the pressure plate 1003, and the pressure plate 1003 is compressed, pushing the limit column 1001 to move downward and compressing the corresponding elastic member 1002. The bottom of the limit column 1001 will contact the upper surface of the pier cap 1111, thereby limiting the walking vehicle 1 to prevent the walking vehicle 1 from moving and maintaining the stability of the present invention during the detection process.

[0029] Then the user removes the latch 52 on the connecting rod 5, and sinks the installation box 6 into the water by moving the connecting rod 5 downward. The length of a single connecting rod 5 is set to one meter. The installation box 6 will first sink into the water close to the water surface, and then the latch 52 is inserted into the limiting hole 51 on the connecting rod 5 closest to the sliding block 4. Then the latch 52 contacts the upper surface of the sliding block 4 to limit the current height of the connecting rod 5 and the installation box 6; then the user controls the electric push rod 2 to retract, driving the connecting block 3, the sliding block 4 and the connecting rod 5 The rubber ring 7 will contact the water-facing surface of the pier cap 1111, and the electric push rod 12 will contract to drive the installation box 6 to squeeze the rubber ring 7, so that it is tightly attached to the water-facing surface of the pier cap 1111 to form a seal, and the external water flow cannot enter the rubber ring 7. Then the user controls the electric slider 63 to slide along the slide rail 62, so that the two sealing doors 61 are separated from each other, and then the installation box 6 is opened, so that the pier cap 1111 is closed. 1 The water-facing surface is connected to the inside of the installation box 6. At this time, there is a small amount of water flow in the rubber ring 7, that is, in the space between the bridge pier cap 1111 and the installation box 6. As the sealing door 61 is opened, it will enter the installation box 6. Under the action of gravity, most of the water will flow downward into the lower chamber of the installation box 6, and a small amount of water entering the upper chamber will also flow from the upper chamber into the lower chamber under the guidance of the inclined partition plate 64. Then, the user controls the water pump 10 to pump out the water flow in the lower chamber and discharge it into the water flow outside the installation box 6. At this time, the water-facing surface of the bridge pier cap 1111 covered by the installation box 6 is in a state of not contacting the external flowing water flow. The user can observe the water-facing surface through the wireless camera 12 to check the erosion of the water flow. Because the flowing water flow outside the installation box 6 is isolated by it, and there is no water flow in the installation box 6, the water-facing surface of the bridge pier cap 1111 can be clearly viewed through the wireless camera 12, and the observation will not be affected by the impact of the flowing water flow, and the line of sight will not be affected by the flowing turbid water flow, so as to ensure the detection result.

[0030] When sampling is required, the electric push rod 211 is controlled to extend, and the mounting plate 201 and the parts connected thereto are pushed to slide on the guide rod 65, so that the grinding roller 205 is close to the water-facing surface of the pier cap 1111 and contacts it, and at the same time, the collecting plate at the entrance of the collecting box 207 will also contact the water-facing surface, and then the motor 202 is controlled to work, and the motor 202 drives the flat gear 1 203 to rotate, and the flat gear 1 203 drives the flat gear 2 206 to rotate through the toothed belt 204, and the flat gear 206 drives the grinding roller 205 to rotate, and the grinding roller 205 will grind the water-facing surface, so that the concrete layer on the water-facing surface falls off, and the fallen concrete falls downward, enters the collecting box 207 through the collecting plate and is collected for subsequent sample testing. Therefore, the sampling process is in a waterless environment, which can prevent water from washing away the sample; after the sampling is completed, the electric push rod 11 is controlled to retract, driving the mounting plate 201 and the parts thereon to reset, and then the electric slider 63 is controlled to drive the sealing door 61 to close, reseal the mounting box 6, and then the mounting box 6 is lifted out of the water through the connecting rod 5 to end the detection; and then if it is necessary to detect other positions, the user releases the pressure on the pressure plate 1003, the elastic member 1002 stretches, and pushes the pressure plate 1003 to drive the limit column 1001 to move upward, and the limit column 1001 is separated from the contact with the upper surface of the pier cap 1111, and the limit on the walking vehicle 1 is released. The user drives the present invention to move to other detection areas by moving the walking vehicle 1.

[0031] The water-facing surface of the pier cap 1111 is washed by water for a long time, and there may be slight unevenness, and even the steel bars of the pier cap 1111 wrapped by concrete are exposed, so that when the rubber ring 7 is attached to the water-facing surface of the pier cap 1111 for sealing, it is impossible to achieve complete sealing, and there is water seepage. Therefore, during the detection process, the water pump 10 is in a continuous working state, and the water flow that penetrates into the lower chamber of the installation box 6 through the rubber ring 7 is continuously discharged. At the same time, the user observes the amount of water that penetrates into the lower chamber of the installation box 6 through the wireless camera 12, and controls the power of the water pump 10. Adaptive adjustment is made to ensure that the water in the lower chamber of the installation box 6 is discharged in time. It should be noted that although there is water seepage when the rubber ring 7 is fitted against the water-facing surface of the pier cap 1111 for sealing, the amount of water seepage is not large. At the same time, the water pump 10 is in a continuous drainage state, so the interior of the installation box 6 will not be filled with the infiltrated water. Compared with underwater robots or personnel diving in flowing water for observation and detection, which are easily affected by water disturbances and turbid water flow affecting the line of sight, the wireless camera 12 of the present invention is not located in flowing water and is not affected by it, so excellent observation results can be obtained.

[0032] Furthermore, there will be loose concrete blocks and debris such as moss and water plants on the water-facing surface of the pier cap 1111, which will make the surface of the pier cap 1111 more uneven, aggravating the water seepage problem caused by the loose fit of the rubber ring 7. Therefore, during the downward movement of the installation box 6, the rear side of the rubber ring 7 does not contact the water-facing surface of the pier cap 1111, and the spring telescopic rod 8 is in an extended state, forcing the cleaning ball 9 to contact the water-facing surface of the pier cap 1111. As a result, when the installation box 6 moves downward, The cleaning ball 9 is aligned with the two vertical edges of the rubber ring 7. When the cleaning ball 9 on the lower side moves downward, it contacts the water-facing surface of the bridge pier cap 1111, and then the debris on the corresponding downward moving path of the cleaning ball 9 on the water-facing surface is cleaned and scraped off. At this time, the two vertical edges of the rubber ring 7 correspond to the vertical cleaning path of the cleaning ball 9. When the installation box 6 moves down to the detection position, the user first drives the installation box 6 to continue to move down by the height of the limit hole 51 through the connecting rod 5, and then limits the connecting rod 5 and the installation box through the latch 52. After the user has lifted the connecting rod 5 and the installing box 6, the user can lift the connecting rod 5 and the installing box 6 to make the connecting rod 5 rise to the height of the two limiting holes 51 and lock the current position. After that, the user moves the installing box 6 left and right through the connecting rod 5, so that the two cleaning balls 9 on the lower side clean out a horizontal path corresponding to the lower horizontal edge of the rubber ring 7 on the water-facing surface of the pier platform 1111. After that, the user moves the connecting rod 5 down by the height of a limiting hole 51 and locks it. At this time, the upper and lower horizontal edges of the rubber ring 7 are aligned with the two horizontal paths respectively. Then, when the rubber ring 7 is pressed tightly on the water-facing surface of the pier platform 1111, the four sides are all located in the cleaning path, which improves the sealing fit of the rubber ring 7 and reduces water seepage.

[0033] It should be noted that when using the present invention, the user can observe the water-facing surface of the pier cap 1111 in advance through the transparent sealing door 61 using the wireless camera 12. If deep pits appear on the water-facing surface, other areas are selected for detection and sampling to avoid the rubber ring 7 being unable to form a seal.

[0034] If it is necessary to detect the surface conditions of the pier cap 1111 at different depths, another connecting rod 5 can be connected to the thread on the connecting rod 5, and the number of connecting rods 5 to be added can be selected according to the required depth, and then the connecting rod 5 can be extended as a whole, so that the installation box 6 can continue to go deeper downward; after the previous detection is completed, the electric slider 63 is controlled to drive the two sealing doors 61 closer to each other, and the installation box 6 is sealed again, and then the electric push rod 2 is controlled to extend, so that the rubber ring 7 is out of contact with the surface of the pier cap 1111, so as to avoid the rubber ring 7 being damaged by friction with the surface of the pier cap 1111 when moving up and down, thereby affecting the sealing effect, and then the installation box 6 can be moved downward by the extended connecting rod 5 to detect and sample the deeper surface of the pier cap 1111.

[0035] As the installation box 6 sinks deeper into the water, the buoyancy from the water flow increases, and the installation box 6 becomes more difficult to descend. If a counterweight is provided for the installation box 6 to facilitate sinking, when the installation box 6 needs to be lifted out of the water, the counterweight of the installation box 6 plus the resistance of the water will make it difficult to lift the installation box 6 out of the water. If a counterweight is provided for the installation box 6, the overall mass of the present invention will increase, which is not conducive to the user's carrying. Therefore, the installation box 6 is made of a lightweight, pressure-resistant acrylic material. During the last inspection, the user observed through the wireless camera 12 in the lower chamber of the installation box 6. If the water flow entering the lower chamber of the installation box 6 did not fill the lower chamber, it was not necessary to use the water pump 10 to lift the water into the lower chamber. All of it is discharged, thereby increasing the deadweight of the installation box 6, which facilitates the sinking of the installation box 6, and as the installation box 6 sinks into deeper water, the water pump 10 is controlled to increase the amount of water filled in the lower chamber of the installation box 6, and thus the deadweight of the installation box 6 is also greater, which is more conducive to the installation box 6 going deeper underwater; when the detection is completed, the water pump 10 is controlled to discharge all the water flow in the lower chamber. At this time, the entire installation box 6 is in an air pressure state, and due to the drainage, the original air inside the installation box 6 is discharged together, so that the air pressure inside the installation box 6 increases, and the installation box 6 located in the water will have greater buoyancy, which is more conducive to floating, saving the user the power to lift the installation box 6 through the connecting rod 5.

[0036] In addition, when the present invention is used to detect the reinforced concrete structure of the load-bearing columns of a house in water, a suitable blank position around the load-bearing column to be detected is selected, the walking vehicle 1 is placed, and then the electric push rod 2 and the connecting rod 5 are adjusted to place the installation box 6 against the load-bearing column corresponding to the required detection surface for detection. If there is no suitable blank position to place the walking vehicle 1, the user can drive the hull to place the walking vehicle 1 of the present invention on the boat, and drive the installation box 6 to rotate by rotating the connecting rod 5, so that the opening surface of the installation box 6 (the surface closed by the sealing door 61) is aligned with the detection surface of the load-bearing column, and then the installation box 6 is placed against the detection surface of the load-bearing column for detection.

[0037] Embodiment 2: Based on embodiment 1, Figure 2-Figure 4 and Figure 7-10 As shown, a conical block 301 is also included; the conical block 301 is welded to the bottom of the installation box 6.

[0038] Sundries such as tree branches and plastic bottles are usually suspended in water. At the same time, the sundries move with the water flow and tend to gather in large quantities on the water-facing surface of the pier cap 1111. The present invention performs detection on the water-facing surface of the pier cap 1111. When it sinks into the water, the bottom touches the tree branches, plastic bottles and other sundries suspended in the water. The buoyancy of the sundries in the water will hinder the present invention from moving downward, affecting the use of the present invention. A conical block 301 is provided at the bottom of the installation box 6. When the present invention moves downward, the conical block 301 will push the sundries and guide them to the left or right side, away from the installation box 6, and be washed away to the left or right side by the water flow, so as to avoid the sundries being blocked directly below the installation box 6 and affecting the present invention from sinking into the water.

[0039] Example 3: Based on Example 1 and Example 2, Figure 1 , Figure 2 and Figure 14-16 As shown, a guide plate 401 is also included; each sealing door 61 is connected to a guide plate 401 on one side facing the outside of the installation box 6 through a mounting rod; the guide plate 401 is arranged at an angle.

[0040] When the present invention is located on the left side or right side of the pier cap 1111 for use, the water flow will flush the plane on the left or right side of the installation box 6, which may easily cause the present invention to be unstable due to the flushing of the water flow during use, affecting the detection process. Therefore, each sealing door 61 is connected to a guide plate 401 on the side facing the outside of the installation box 6 through a mounting rod. When the present invention is located on the left side or right side of the pier cap 1111 for use, the water flow will flush the corresponding inclined guide plate 401, and be guided by the guide plate 401 in a direction away from the pier cap 1111, reducing the flushing force of the water flow on the installation box 6, and avoiding the instability of the present invention caused by the flushing of the water flow; at the same time, during the opening process of the sealing door 61, it will extend to the left and right sides of the installation box 6, and the guide plate 401 on the surface flushed by the positive water flow plays a role in reducing the flushing force of the water flow, which helps the sealing door 61 to open and extend out of the installation box 6.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
