Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a sampling device for testing recycled concrete. Background Technology

[0002] Recycled concrete, as an environmentally friendly building material, has been widely used in the modern construction industry. Sampling and testing are required during the use of recycled concrete.

[0003] Among them, announcement number CN221199037U discloses a recycled concrete testing and sampling device, which relates to the field of recycled concrete testing and sampling devices. It includes a base plate, a limiting post fixed to the top of the base plate, a fixing orifice plate fixed to the top of the limiting post, a first motor fixed to the top of the fixing orifice plate, and a lead screw fixed to the bottom end of the first motor extending through to the bottom end of the fixing orifice plate. A sliding orifice plate is threadedly connected to the outer side of the lead screw and sleeved on the outer side of the limiting post. This utility model, by setting a material removal component, allows for the removal of a concrete sample column from inside the drill pipe by activating a second motor to cause a rack and a pressing plate to squeeze the concrete sample column inside the drill pipe, thus detaching the concrete sample column from the drill pipe. This differs from methods that require striking the outer wall of the drill pipe to detach the concrete sample column, as the outer wall of the drill pipe is not damaged by the impact, extending the life of the drill pipe.

[0004] The device extracts the concrete sample column by pressing it with a pressing plate. However, during use, because the concrete sample column is tightly connected to the sampling cylinder, when the sample column is pushed outward, it will rub against the side wall of the sampling cylinder, causing wear on the side wall of the sampling cylinder and making the sample column prone to being squeezed and damaged.

[0005] Therefore, it is necessary to invent a recycled concrete testing and sampling device to solve the above problems. Utility Model Content

The output end of the drive motor drives the outer sampling cylinder and the inner sampling cylinder to rotate through the first fixed plate to sample the concrete.

[0015] By adopting the above technical solution, during the splicing process of the sampling inner cylinder, the snap-fit ​​block is snapped into the inside of the snap-fit ​​groove, thereby improving the stability of the sampling inner cylinder.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 4The device shown is a recycled concrete testing and sampling device, comprising two sets of supporting base plates 1. Two sets of positioning columns 11 are fixedly connected to the surface of each set of supporting base plates 1. A lifting plate 2 is arranged between the left and right positioning columns 11. A drive motor 23 is fixedly installed on the upper surface of the lifting plate 2. Two sets of positioning holes 21 are opened at both ends of the lifting plate 2. The positioning columns 11 are slidably connected to the positioning holes 21. A support frame 22 is fixedly connected to the middle position of the upper surface of the lifting plate 2. The drive motor 23 is located inside the support frame 22. The upper end of the positioning columns 11 is fixedly connected to... A supporting top plate 12 is provided, and a positioning cylinder 13 is fixedly connected to the middle of the supporting top plate 12. A threaded rod 14 is slidably connected inside the positioning cylinder 13. The lower end of the threaded rod 14 is fixedly connected to the upper end of the support frame 22. A positioning sleeve 15 is rotatably connected to the upper end of the positioning cylinder 13. A connecting cylinder 16 is fixedly connected to the upper end of the positioning sleeve 15. The connecting cylinder 16 is threadedly connected to the threaded rod 14. A handwheel 17 is fixedly connected to the side of the connecting cylinder 16. A first fixing plate 24 is fixedly connected to the output end of the drive motor 23. A sampling module is provided on the lower side of the first fixing plate 24.

[0034] The positioning column 11 has a scale on its surface to facilitate observation of the descent distance of the lifting plate 2, thereby determining the sampling depth of the sampling module. During the sampling process, the sampling module is adjusted to the upper side of the sampling point. At this time, the drive motor 23 drives the sampling module to rotate. Next, the handwheel 17 is rotated, which drives the connecting cylinder 16 to rotate, thereby driving the positioning sleeve 15 to rotate at the upper end of the positioning cylinder 13. During the rotation of the connecting cylinder 16, the threaded rod 14 is pushed downward. At this time, the lower end of the threaded rod 14 pushes the support frame 22 and the lifting plate 2 downward, thereby drilling the sampling mechanism into the concrete to sample the concrete. During the downward pushing of the lifting plate 2, the scale on the surface of the positioning column 11 can be observed to control the sampling depth.

[0035] In addition, after sampling is completed, the drive motor 23 stops rotating, and then the handwheel 17 is rotated in the opposite direction, thereby raising the threaded rod 14 and driving the sampling module to rise.

[0036] See Figure 2 , Figure 5 and Figure 6The sampling module includes a sampling outer cylinder 3, a second connecting hole 33, an insertion groove 34, a sampling inner cylinder 4, a second fixing screw 41, an insertion plate 44, and cutting teeth 45. The sampling inner cylinder 4 consists of two half-cylinders. The surface of the first fixing plate 24 has two sets of first connecting holes 25. The upper surface of the sampling outer cylinder 3 is fixedly connected to the second fixing plate 31. The upper surface of the second fixing plate 31 is fixedly connected to two sets of first fixing screws 32. The upper surface of the sampling outer cylinder 3 has two sets of second connecting holes 33. The insertion groove 34 is located at the lower end of the sampling outer cylinder 3. The second fixing plate 31 is clamped on the lower surface of the first fixing plate 24. The first fixing screw 32 is inserted into the first fixing plate 24. Inside the connecting hole 25, the upper end of the first fixing screw 32 is threaded with a nut, the plug plate 44 is fixedly connected to the side wall of the sampling inner cylinder 4, the cutting tooth 45 is fixedly connected to the lower end of the plug plate 44, the plug plate 44 is inserted into the inside of the plug groove 34, two sets of second fixing screws 41 are fixedly connected to the upper surface of the sampling inner cylinder 4, the second fixing screws 41 are inserted into the inside of the second connecting hole 33, the upper end of the second fixing screws 41 is threaded with a nut, multiple sets of snap-fit ​​blocks 42 are fixedly connected to the side of the left half of the sampling inner cylinder 4, and multiple sets of snap-fit ​​grooves 43 are opened on the side of the right half of the sampling inner cylinder 4, the snap-fit ​​blocks 42 are snapped into the inside of the snap-fit ​​grooves 43.

[0037] Specifically, during the installation of the sampling module, firstly, the snap-fit ​​block 42 is snapped into the snap-fit ​​groove 43 to splice the two half-cylinders into the sampling inner cylinder 4. Next, the sampling inner cylinder 4 is inserted into the sampling outer cylinder 3, and the plug plate 44 is inserted into the plug groove 34 to clamp the sampling inner cylinder 4 and the sampling outer cylinder 3 together. At the same time, the second fixing screw 41 is inserted into the second connecting hole 33 and locked with a nut, thereby fixing the sampling inner cylinder 4 inside the sampling outer cylinder 3. Then, the second fixing plate 31 is snapped into the lower side of the first fixing plate 24, and the first fixing screw 32 is inserted into the first connecting hole 25 and locked with a nut, thereby locking the sampling outer cylinder 3 and the first fixing plate 24 together to sample the concrete.

[0038] In addition, after sampling is completed, the nut on the surface of the first fixing screw 32 is removed, the outer sampling cylinder 3 is separated from the first fixing plate 24, the nut on the surface of the second fixing screw 41 is removed, the inner sampling cylinder 4 is separated from the outer sampling cylinder 3, the inner sampling cylinder 4 is then split into two half cylinders, and the support is used to remove the concrete sample column, which helps to maintain the integrity of the concrete sample column.

[0039] The working principle of this utility model is as follows: During the process of taking a concrete sample column, the sampling inner cylinder 4 is removed from the sampling outer cylinder 3. Then, the sampling inner cylinder 4 is split into two half cylinders, which facilitates the quick removal of the concrete sample column, avoids wear on the inner wall of the sampling cylinder, and improves the integrity of the concrete sample column to prevent damage. At the same time, through optimized structural design, the recycled concrete testing and sampling device of this technology is not only simple to operate and convenient to use, but also has high sampling accuracy and efficiency, which can meet the industry's demand for high-precision and high-efficiency testing and sampling.
