Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for on-site density detection of hydraulic roller compacted concrete. Background Technique

[0002] Hydraulic engineering refers to technical workers in water conservancy projects, who are responsible for the survey, planning, design, construction, scientific research and management of water conservancy projects. The sampling device for on-site density detection of hydraulic roller compacted concrete is an important tool to ensure the construction quality of concrete. It can quickly and accurately obtain the density data of concrete on-site, so as to evaluate the compaction degree and quality of concrete. There are still certain defects in the existing sampling devices when in use.

[0003] In the prior art, the sampling device for on-site density detection of concrete is an indispensable important tool in concrete construction. It can help construction workers quickly and accurately evaluate the compaction degree and quality of concrete, providing a strong guarantee for the improvement of construction quality. When using the traditional sampling device, tools are needed to place the concrete into the sampling bucket, making the height of the concrete higher than the sampling bucket, and using a tamper to tamp the concrete in the sampling bucket to reduce the voids inside the concrete. Then, use tools to scrape off the part of the concrete above the bucket mouth of the sampling bucket, and subsequently use a trowel to level the surface of the concrete. A glass plate can be used to check whether the surface of the concrete is flat. At this time, the sampling bucket and the concrete inside it can be weighed. The density of the concrete is equal to the total weight of the concrete and the sampling bucket minus the weight of the sampling bucket, divided by the volume of the sampling bucket, and finally multiplied by 1000 to obtain the density of the concrete. During this process, the concrete is prone to adhere to the outside of the port of the sampling bucket, causing the sampling bucket to be dirty and requiring frequent cleaning by personnel, resulting in low detection efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sampling device for on-site density detection of hydraulic roller compacted concrete to solve the problem that the outside of the port of the sampling device in the current market is prone to adhere to concrete as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A sampling device for on-site density detection of hydraulic roller compacted concrete, comprising: a sampling bucket, a handle and a tamper. The handle is welded to the outside of the sampling bucket, and the tamper is arranged on the outside of the handle. A connecting block is welded to the outside of the sampling bucket. A limiting rod is slidably connected inside the connecting block. A limiting block is connected to the end of the limiting rod close to the sampling bucket. A return spring is connected between the limiting block and the connecting block. A collecting hopper is arranged on the outside of the sampling bucket. A baffle cylinder is connected to the inner surface of the collecting hopper. An inserting block is connected to the bottom of the collecting hopper.

[0006] Preferably, a clamping groove matching the size of the end of the limiting block is formed inside the clamping block close to the limiting block.

[0007] Preferably, through holes matching the outer diameter of the sampling bucket are formed through the interiors of the collecting hopper and the material blocking cylinder.

[0008] Preferably, a support plate is welded to the outer side of the sampling bucket, and a vertical column is welded to the top of the support plate.

[0009] Preferably, fixing blocks are connected to the top end and the outer side of the vertical column, and a rotating block is rotatably connected to the outer side of the vertical column close to the fixing block.

[0010] Preferably, a moving block is connected to the end of the rotating block, and a scraping plate is connected to the bottom end of the moving block.

[0011] Preferably, the scraping plate is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the on-site density detection and sampling device for hydraulic roller-compacted concrete, when the collecting hopper descends, it can drive the material blocking cylinder and the clamping block to move. When the inner sides of the material blocking cylinder all move to the outer side of the sampling bucket, the collecting hopper and the material blocking cylinder can be sleeved on the outer side of the sampling bucket. At the same time, the bottom end of the clamping block can be inserted into the connecting block. When one side of the scraping plate moves to the surface of the sampling bucket port, the scraping plate can scrape the concrete higher than the sampling bucket port. After scraping, the surface of the scraping plate can be cleaned with a rag, so that there is no need to use a measuring ruler to scrape the concrete, and this operation method is simple and convenient. The scraping plate is not easy to lose, and at the same time, it does not affect the use of the sampling bucket.

[0013] 1. The on-site density detection sampling device for concrete is a relatively simple and direct detection and sampling tool. It can help hydraulic engineers quickly and accurately evaluate the compaction degree and quality of concrete. During the use of the sampling device, concrete is likely to adhere to the outer side of the port of the sampling bucket, which requires frequent cleaning by personnel, is time-consuming, and will also reduce the detection efficiency. When the collecting hopper descends, it can drive the material blocking cylinder and the plug-in block to move. When the inner sides of the material blocking cylinders all move to the outside of the sampling bucket, the collecting hopper and the material blocking cylinder can be sleeved on the outside of the sampling bucket. At the same time, the bottom end of the plug-in block can be inserted into the connecting block, and the bottom end of the plug-in block can squeeze the inclined surface of the limiting block. When the limiting block is squeezed, it can drive the limiting rod to move. When the return spring is squeezed to a certain extent, the end of the plug-in block can penetrate the connecting block, so that the bottom of the collecting hopper can fall on the top of the connecting block. When the limiting block resets, its end can be stuck inside the plug-in block. When adding concrete to the sampling bucket and using a trowel to level it, once the concrete falls, the collecting hopper can collect the concrete on the outer side of the port of the sampling bucket, so that the concrete is not easily adhered to the outer side of the port of the sampling bucket, avoiding unnecessary cleaning of the outer side of the sampling bucket by personnel, and thus improving the detection efficiency.

[0014] 2. During the use of the on-site density detection sampling device for concrete, a measuring ruler is usually used to scrape off the concrete higher than the port of the sampling bucket. This method will cause the ruler to be dirty. If it is not cleaned in time, it will affect the accuracy of the measuring ruler. When the moving block moves, it can drive the rotating block and the scraper to move. And when the rotating block moves, it can rotate through the column. When one side of the scraper moves to the surface of the port of the sampling bucket, the scraper can scrape off the concrete higher than the port of the sampling bucket. After scraping, the surface of the scraper can be cleaned with a rag, so there is no need to use a measuring ruler to scrape the concrete, and this operation method is simple and convenient. The scraper is not easy to lose, and it does not affect the use of the sampling bucket at the same time. Description of the Drawings

Detailed implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 It can be seen that the present invention provides a technical solution: a sampling device for on-site density detection of hydraulic roller-compacted concrete, including: a sampling bucket 1, a handle 2 and a rammer 3. A handle 2 is welded to the outside of the sampling bucket 1, and a rammer 3 is arranged on the outside of the handle 2. A connecting block 4 is welded to the outside of the sampling bucket 1. A limiting rod 5 is slidably connected inside the connecting block 4. The end of the limiting rod 5 close to the sampling bucket 1 is connected with a limiting block 6. A return spring 7 is connected between the limiting block 6 and the connecting block 4. A collecting hopper 8 is arranged on the outside of the sampling bucket 1. The inner surface of the collecting hopper 8 is connected with a material blocking cylinder 9. The bottom of the collecting hopper 8 is connected with an inserting block 10. A card slot matching the size of the end of the limiting block 6 is opened inside the inserting block 10 close to the limiting block 6. Through holes matching the outer diameter size of the sampling bucket 1 are penetrated through the inside of both the collecting hopper 8 and the material blocking cylinder 9.

[0022] During specific implementation, the on-site density detection sampling device for concrete is a relatively simple and direct detection sampling tool, which can help hydraulic engineers quickly and accurately evaluate the compaction degree and quality of concrete. During the use of the sampling device, concrete is likely to adhere to the outer side of the port of the sampling bucket 1, requiring frequent cleaning by personnel, which is time-consuming and also reduces the detection efficiency. Before the concrete is placed inside the sampling bucket 1, the collecting hopper 8 can be moved directly above the sampling bucket 1, and at the same time, the position of the insertion block 10 can be adjusted directly above the connecting block 4, and the collecting hopper 8 can be slowly lowered. When the collecting hopper 8 descends, it can drive the material blocking cylinder 9 and the insertion block 10 to move. When the inner sides of the material blocking cylinder 9 all move to the outside of the sampling bucket 1, the collecting hopper 8 and the material blocking cylinder 9 can be sleeved on the outside of the sampling bucket 1. At the same time, the bottom end of the insertion block 10 can be inserted into the connecting block 4, and the bottom end of the insertion block 10 can squeeze the inclined surface of the limiting block 6. When the limiting block 6 is squeezed, it can drive the limiting rod 5 to move, and the limiting block 6 can squeeze the return spring 7. When the return spring 7 is squeezed to a certain extent, the end of the insertion block 10 can penetrate through the connecting block 4, so that the bottom of the collecting hopper 8 can fall on the top of the connecting block 4. At the same time, the limiting block 6 can be reset through the return spring 7. When the limiting block 6 is reset, its end can be stuck inside the insertion block 10, and at this time, the position of the collecting hopper 8 can be fixed.

[0023] Refer to Figures 1-4 It can be seen that when adding concrete and using a trowel to level the inside of the sampling bucket 1, once the concrete drops, the collecting hopper 8 can collect the concrete on the outer side of the port of the sampling bucket 1, making it difficult for the concrete to adhere to the outer side of the port of the sampling bucket 1, avoiding unnecessary cleaning of the outside of the sampling bucket 1 by personnel, and thus improving the detection efficiency.

[0024] Refer to Figure 1 and Figure 2 It can be seen that a support plate 11 is welded to the outside of the sampling bucket 1, a column 12 is welded to the top of the support plate 11, fixed blocks 13 are connected to the top end and the outside of the column 12, a rotating block 14 is rotatably connected to the outside of the column 12 near the fixed block 13, a moving block 15 is connected to the end of the rotating block 14, a scraping plate 16 is connected to the bottom end of the moving block 15, the scraping plate 16 is made of stainless steel, and the shape of the moving block 15 is T-shaped.

[0025] During specific implementation, when the on-site density detection sampling device for concrete is in use, a measuring ruler is usually used to scrape the concrete above the port of the sampling bucket 1. This method can cause the ruler to become dirty. If it is not cleaned in time, it will affect the accuracy of the measuring ruler. When the concrete inside the sampling bucket 1 is higher than the port of the sampling bucket 1, the moving block 15 can be pushed towards the direction close to the port of the sampling bucket 1. When the moving block 15 moves, it can drive the rotating block 14 and the scraping plate 16 to move. And when the rotating block 14 moves, it can rotate through the column 12. When one side of the scraping plate 16 moves to the surface of the port of the sampling bucket 1, the scraping plate 16 can scrape the concrete above the port of the sampling bucket 1.

[0026] Referring to Figure 1 and Figure 2 it can be seen that after scraping, the surface of the scraping plate 16 can be cleaned with a rag, so there is no need to use a measuring ruler to scrape the concrete. Moreover, this operation method is simple and convenient, the scraping plate 16 is not easy to be lost, and it does not affect the use of the sampling bucket 1 either.

[0027] In summary, when using this on-site density detection sampling device for hydraulic roller-compacted concrete, the collecting hopper 8 can be moved directly above the sampling bucket 1. At the same time, the position of the plug-in block 10 is adjusted directly above the connecting block 4, and the collecting hopper 8 is slowly lowered. When adding concrete and using a trowel to level the concrete inside the sampling bucket 1, once the concrete drops, the collecting hopper 8 can collect the concrete outside the port of the sampling bucket 1, so that the concrete is not easily adhered to the outside of the port of the sampling bucket 1, avoiding unnecessary cleaning of the outside of the sampling bucket 1 by personnel, thereby improving the detection efficiency. After scraping, the surface of the scraping plate 16 can be cleaned with a rag, so there is no need to use a measuring ruler to scrape the concrete. Moreover, this operation method is simple and convenient, the scraping plate 16 is not easy to be lost, and it does not affect the use of the sampling bucket 1 either. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
