Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the technical field of concrete sampling, and in particular, to a concrete sampling device for highway construction. Background Art
[0002] In highway construction, concrete sampling is the core link of quality control. Its timing and purpose are directly related to the safety and durability of the engineering structure. In order to control the quality of highway construction, sampling is generally carried out before construction, that is, at the tank truck unloading and pouring site, to make maintenance specimens for predicting structural strength development and verifying environmental adaptability. After construction, the hardened highway pavement is sampled using the core drilling method through a sampling device to analyze indicators such as aggregate distribution, honeycomb defects, and carbonization depth.
[0003] During highway construction, when concrete begins to set but has not yet fully solidified, it is very important to sample the concrete. First, sampling can be used to detect key performance indicators of concrete such as strength, durability, and density, so as to promptly discover and correct potential quality problems. In addition, sampling during the initial setting stage of concrete can detect problems in the concrete at an early stage, such as improper mix ratios and improper use of admixtures. If these problems are discovered after the concrete is fully solidified, they will be difficult to correct, so concrete sampling is necessary.
[0004] In the prior art, during sampling, concrete at different depths needs to be sampled because the conditions of concrete after construction vary greatly at different depths. However, during the sampling process, the traditional single-layer sampling device needs to be repeatedly inserted into the concrete, cleaned, and then reinserted into the concrete. This is very time-consuming, and when the same device is used for multiple samplings, the residual concrete sample will contaminate subsequent samples. That is, after shallow sampling, the residual concrete in the device may be mixed into the deep sample, thereby affecting the authenticity of the composition data of samples at different depths. Summary of the Invention
[0005] In order to overcome the above-mentioned defects, the present invention provides a concrete sampling device for highway construction, which is used to solve the technical problem in the prior art that when traditional single-layer sampling devices perform multiple samplings of concrete at different depths, the residual samples will contaminate subsequent samples, thereby affecting the composition of samples at different depths and reducing the authenticity of the data.

[0026] like Figures 1 to 6 The figure shows a concrete sampling device for highway construction in one embodiment of the present invention, comprising a mobile platform 1, a material-waiting tank 2, a conveying component, a turning component, a material-taking component and a conveying component. A plurality of material-waiting tanks 2 are provided on the mobile platform 1, and the plurality of material-waiting tanks 2 are coaxially arranged and connected end to end. The conveying component comprises a primary conveying cylinder 3 and a mounting cylinder 4. A plurality of primary conveying cylinders 3 are fixedly installed at equal distances on the mobile platform 1, and the plurality of primary conveying cylinders 3 correspond one to one with the plurality of material-waiting tanks 2. The input end of each primary conveying cylinder 3 is connected to the mounting cylinder 4 through a feeding rack 5, wherein the feeding rack 5 is connected to the middle position of the mounting cylinder 4, and a turning component is provided in each material-waiting tank 2 for turning over the concrete sample entering the material-waiting tank 2. The material assembly includes a rotating drum 6, a scraper 7, a stirring rod 8 and a feeding part. A rotating drum 6 is rotatably installed inside each waiting tank 2. Several rotating drums 6 are coaxially arranged. A scraper 7 is fixedly installed on each rotating drum 6. The scraper 7 slides against the inner wall of the waiting tank 2. Several stirring rods 8 are fixedly installed at equal distances on each rotating drum 6. A feeding part is installed on each waiting tank 2. The feeding part is normally in a closed state and is used to send out the material in the waiting tank 2. It also includes a transmission shaft 9 and a first driving motor 10. A transmission shaft 9 is rotatably installed between several waiting tanks 2. Several rotating drums 6 are coaxially fixedly connected to the transmission shaft 9. The first driving motor 10 is fixedly installed on the mobile platform 1, and the output end of the first driving motor 10 is fixedly connected to the transmission shaft 9.
[0027] Specifically, when sampling is required, the mobile platform 1 is first moved to the sampling position, and then the position of the material taking component is adjusted so that the position of each material taking component in the vertical direction is inconsistent, thereby adapting to concrete of different depths and facilitating simultaneous sampling of concrete of different depths. When sampling, different material taking components are sent to positions of different depths in the concrete, and then the corresponding material taking components are opened to perform sampling operations on concrete of different depths. The taken concrete samples are then sent into the corresponding first-level conveying cylinder 3 through the mounting cylinder 4 and the feeding rack 5. At this time, the conveying assembly is opened to send it into the waiting tank 2 at the corresponding position, and then the first driving motor 10 is turned on. The first driving motor 10 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives several rotating cylinders 6 to rotate. The rotating cylinder 6 drives the corresponding scraper 7 and the stirring rod 8 to rotate, thereby slowing down the solidification speed of the concrete in the waiting tank 2 to keep it fluid. When the sample needs to be taken out, the corresponding feeding part can be opened.
[0028] The above, such as Figure 3 、 Figure 4 As shown, the feeding part includes a feed hopper 11, a discharge hopper 12 and a first driving member 13. The feed hopper 11 is fixedly installed on the top of each waiting tank 2. The feed hopper 11 is located at the lower part of the output end of the first-level conveying cylinder 3. The output end of each waiting tank 2 is fixedly installed with a discharge hopper. Each discharge hopper 12 is fixedly installed with a first driving member 13. Each first driving member 13 is fixedly installed with a blocking block 14, and the blocking block 14 is adapted to the discharge end of the waiting tank 2.
[0029] Specifically, when the conveying assembly delivers the concrete sample into the feed hopper 11 at the corresponding position through the first-level conveying cylinder 3, the concrete sample enters the interior of the waiting tank 2. When the concrete sample needs to be taken out, the first driving member 13 is opened, and the corresponding blocking block 14 is retracted, so that the concrete sample is discharged from the discharge hopper 12, and then the first driving member 13 is opened again to move the blocking block 14 back to its original position.
[0030] It should be added that after taking out the sample, the corresponding waiting tank 2 needs to be cleaned to prepare for the next sampling.
[0031] As shown in Figure 5, Figure 6As shown, a material taking assembly is installed inside each mounting cylinder 4 for sampling concrete at different depths. The material taking assembly includes a secondary conveying cylinder 15, a through slot 19, a second driving member 16, a second driving motor 17, a first auger 18 and a positioning portion. A secondary conveying cylinder 15 is slidably installed inside each mounting cylinder 4. A through slot 19 is provided on each secondary conveying cylinder 15, which corresponds to the position of the feeding rack 5. The axial dimension of the through slot 19 is larger than the dimension of the feeding rack 5. A second driving member 16 is fixedly installed on the inner top wall of each mounting cylinder 4. A second driving motor 17 is fixedly installed on the top of each secondary conveying cylinder 15. A first auger 18 is rotatably installed inside each secondary conveying cylinder 15, and the first auger 18 is fixedly connected to the output end of the second driving motor 17. An adjusting portion is installed on the top of each secondary conveying cylinder 15 for adjusting the relative position of the secondary conveying cylinder 15 and the mounting cylinder 4.
[0032] Specifically, when the mobile platform 1 is moved to the sampling position, the position of the secondary conveying cylinder 15 in the mounting cylinder 4 is preliminarily adjusted through the setting of the position adjustment portion, so that different secondary conveying cylinders 15 are in different positions, thereby meeting the requirements of sampling at different depths of concrete. When sampling, several second driving members 16 are turned on at the same time, and the second driving members 16 push the corresponding secondary conveying cylinders 15 to move until the secondary conveying cylinders 15 are moved to the corresponding position, and then the second driving motor 17 can be turned on, and the second driving motor 17 drives the first auger 18 to rotate, thereby moving the concrete to the inside of the secondary conveying cylinder 15, and discharge it into the feeding rack 5 through the setting of the through slot 19.
[0033] Among them, Figure 5 As shown, since the axial size of the through slot 19 is larger than the size of the feeding rack 5, that is, when the secondary conveying cylinder 15 moves downward, the input end of the feeding rack 5 is always inside the through slot 19, thereby facilitating the transportation of concrete.
[0034] The above, such as Figure 5 、 Figure 6 As shown, the positioning portion includes an inner sleeve 20, an outer sleeve 21 and a positioning component. The inner sleeve 20 is fixedly installed on the top of each secondary conveying cylinder 15, and the outer sleeve 21 is sleeved on the outside of the inner sleeve 20. The outer sleeve 21 is fixedly connected to the output end of the second driving member 16. A positioning component is installed between each secondary conveying cylinder 15 and the mounting cylinder 4 for adjusting the relative position of the secondary conveying cylinder 15 and the mounting cylinder 4.
[0035] Specifically, when adjusting the relative position between the secondary conveying cylinder 15 and the installation cylinder 4, the relative position between the inner sleeve 20 and the outer sleeve 21 is adjusted by adjusting the positioning component, thereby adjusting the relative position between the secondary conveying cylinder 15 and the installation cylinder 4.
[0036] The above, such as Figure 5 、 Figure 6 As shown, the positioning component includes a square rod 22, a screw rod 24 and a nut 25. A square rod 22 is rotatably installed on the top of each mounting cylinder 4, and a handwheel 23 is fixedly installed on the top of the square rod 22. A screw rod 24 is slidably installed on each square rod 22, and the bottom end of the screw rod 24 is rotatably installed on the secondary conveying cylinder 15. A nut 25 is threadedly mounted on each screw 24, and the nut 25 is fixedly installed on the outer sleeve 21.
[0037] Specifically, when adjusting the relative position between the inner sleeve 20 and the outer sleeve 21 at the corresponding position, hold the hand wheel 23 and rotate the square rod 22 through the hand wheel 23. The square rod 22 drives the corresponding screw rod 24 to rotate, and the screw rod 24 drives the nut 25 to move. Through the cooperation of the screw rod 24 and the nut 25, the relative position of the inner sleeve 20 and the outer sleeve 21 at the corresponding position is adjusted.
[0038] like Figure 2 As shown, a conveying assembly is installed inside each first-level conveying cylinder 3 for delivering the taken out sample into the waiting tank 2. The conveying assembly includes a second auger 26, a transmission bracket 27 and a driving part. A second auger 26 is rotatably installed inside each first-level conveying cylinder 3. The transmission bracket 27 is fixedly installed on the top of multiple first-level conveying cylinders 3. The driving part is installed inside the transmission bracket 27 and is used to simultaneously drive the second auger 26 in multiple first-level conveying cylinders 3 to rotate.
[0039] Specifically, after the concrete is fed into the feeding rack 5, the concrete entering the feeding rack 5 enters the first-level conveying cylinder 3. At this time, the driving part is turned on, and the driving part simultaneously drives the second augers 26 inside several first-level conveying cylinders 3 to rotate, thereby feeding the concrete entering the first-level conveying cylinder 3 into the waiting tank 2 at the corresponding position.
[0040] The above, such as Figure 2 As shown, the driving part includes a driven bevel gear 28, a driving shaft 29, a driving bevel gear 30 and a third driving motor 31. A plurality of driven bevel gears 28 are rotatably installed inside the transmission bracket 27 at equal intervals. The plurality of driven bevel gears 28 correspond one-to-one with the plurality of second augers 26 and are fixedly connected. A driving shaft 29 is rotatably installed inside the transmission bracket 27. A plurality of driving bevel gears 30 are fixedly installed on the driving shaft 29 at equal intervals. The plurality of driving bevel gears 30 correspond one-to-one with the plurality of driven bevel gears 28 and mesh with each other. The third driving motor 31 is fixedly installed on the transmission bracket 27, and the output end of the third driving motor 31 is fixedly connected to the driving shaft 29.
[0041] Specifically, when driving the second auger 26 to rotate, the third drive motor 31 is turned on, and the third drive motor 31 drives the drive shaft 29 to rotate. The drive shaft 29 simultaneously drives multiple active bevel gears 30 to rotate, thereby simultaneously driving multiple second auger 26 to rotate through the corresponding driven bevel gears 28.
[0042] The working principle or usage process of this application is as follows: When sampling is required, the mobile platform 1 is first moved to the sampling position, and then the position of the second conveying cylinder is adjusted so that the position of each second conveying cylinder is inconsistent in the vertical direction, thereby adapting to concrete of different depths and facilitating simultaneous sampling of concrete of different depths. When adjusting the position of the secondary conveying cylinder 15 in the mounting cylinder 4, hold the handwheel 23 and rotate the square rod 22 through the handwheel 23. The square rod 22 drives the corresponding screw rod 24 to rotate, and the screw rod 24 drives the nut 25 to move. Through the cooperation of the screw rod 24 and the nut 25, the relative position of the inner sleeve 20 and the outer sleeve 21 at the corresponding position is adjusted, thereby making a preliminary adjustment to the position of the secondary conveying cylinder 15 in the mounting cylinder 4 so that different secondary conveying cylinders 15 are in different positions, thereby meeting the requirements of sampling at different depths of concrete.
[0043] When sampling, several second driving members 16 are turned on at the same time. The second driving members 16 push the corresponding secondary conveying cylinder 15 to move through the setting of the inner sleeve 20 and the outer sleeve 21 until the secondary conveying cylinder 15 is moved to the corresponding position. At this time, the lower end of the secondary conveying cylinder 15 enters the interior of the concrete, and the bottoms of several secondary conveying cylinders 15 are located at different depths inside the concrete. At this time, the second driving motor 17 can be turned on, and the second driving motor 17 drives the first auger 18 to rotate, thereby moving the concrete to the interior of the secondary conveying cylinder 15, and discharge it into the feeding rack 5 through the setting of the through slot 19.
[0044] After the concrete is fed into the feeding rack 5, the concrete entering the feeding rack 5 enters the first-level conveying cylinder 3. At this time, the third driving motor 31 is turned on, and the third driving motor 31 drives the driving shaft 29 to rotate. The driving shaft 29 simultaneously drives multiple active bevel gears 30 to rotate, thereby simultaneously driving multiple second augers 26 to rotate through the corresponding driven bevel gears 28, so that the concrete entering the first-level conveying cylinder 3 is fed into the feed hopper 11 at the corresponding position, and the concrete sample enters the waiting tank 2.
[0045] In order to slow down the solidification speed of concrete, the first driving motor 10 is turned on, and the first driving motor 10 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives several rotating drums 6 to rotate, and the rotating drums 6 drive the corresponding scrapers 7 and stirring rods 8 to rotate, thereby slowing down the solidification speed of concrete in the material tank 2 to keep it fluid. When the concrete sample needs to be taken out, the first driving member 13 is turned on, and the corresponding blocking block 14 is retracted, so that the concrete sample is discharged from the discharge hopper 12, and then the first driving member 13 is turned on again to move the blocking block 14 back to its original position.
