Description

Technical Field

[0001] The utility model relates to the technical field of concrete bubble detection, and particularly relates to an adjustable fair-faced concrete bubble detection device. Background Technique

[0002] In order to ensure the construction quality of the self-compacting concrete filling layer of the ballastless track, relevant standards require that on-site slab uncovering tests be carried out on the self-compacting concrete filling layer before and during construction. The main inspection items include surface bubbles, surface density, surface fullness, etc. The existing patent (publication number: CN115388764A) discloses a concrete surface bubble detection device. The invention can flatten the plasticine block through the screed plate by setting the detection cover and the screed plate, so as to facilitate re-detection. With the cooperation of the detection cover, it can prevent the plasticine block from spreading to both sides and ensure good results after multiple uses. However, in actual application, since the plasticine block will volatilize the contained moisture when exposed to the air for a long time, the plasticine block is likely to dry quickly, losing its deformation function and being not conducive to the long-term preservation of the plasticine block. For this reason, we propose an adjustable fair-faced concrete bubble detection device. Content of the Utility Model

Specific implementation mode

[0018] The following combines the accompanying drawings and embodiments to further describe the specific implementation mode of the present invention. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: an adjustable fair-faced concrete bubble detection device, including a column 1 and a detection cover 3 that are fixedly connected to each other. The column 1 and the detection cover 3 are vertically arranged. Inside the detection cover 3, there are a piston plate 5 and a plasticine block 7 connected up and down. A screw rod 2 with its bottom end movably connected to the piston plate 5 is threadedly connected inside the column 1. A threaded hole matching the screw rod 2 is opened inside the column 1. The top end of the screw rod 2 can be fixedly provided with a rotating rod. The bottom end of the screw rod 2 is connected to the top of the piston plate 5 through a rotating seat. By rotating the rotating rod, the screw rod 2 rotates, and then the screw rod 2 moves up and down inside the column 1, driving the piston plate 5 to move up and down, so that the plasticine block 7 moves up and down. When the plasticine block 7 moves downward, it will fill the bubble holes on the surface of the concrete slab. The detection cover 3 is transparent to facilitate observing the heights of the piston plate 5 and the plasticine block 7 inside the detection cover 7 and facilitating adjusting the height positions of the piston plate 5 and the plasticine block 7. And the bottom end of the detection cover 3 is connected with a magnetic attraction cover 4;

[0020] Furthermore, a plurality of magnetic attraction strips 8 are installed at the bottom end of the detection cover 3. The magnetic attraction strips 8 are prior art that has been publicly disclosed. The magnetism carried by the magnetic attraction strips 8 is opposite to that of the magnetic attraction cover 4. A magnetic coating I is coated on the outer surface of the magnetic attraction cover 4. The magnetism carried by the magnetic coating I is opposite to that of the magnetic attraction strips 8. Thus, using the magnetic adsorption force, the magnetic attraction cover 4 is stably connected to the bottom end of the detection cover 3. A magnetic attraction frame 9 is fixed on the column 1. The magnetism carried by the magnetic attraction frame 9 is opposite to that of the magnetic attraction cover 4. A magnetic coating II opposite to the magnetism carried by the magnetic coating I is coated on the outer surface of the magnetic attraction frame 9. Thus, using the magnetic adsorption force, the magnetic attraction cover 4 and the magnetic attraction frame 9 are adsorbed and fixed. After removing the magnetic attraction cover 4 from the bottom end of the detection cover 3, it can be placed on the magnetic attraction frame 9 for placement;

[0021] Above the detection cover 3, there is a water storage box 10 communicated with its interior;

[0022] Furthermore, a lid 11 is connected to the water storage box 10. By opening the lid 11, clean water can be injected into the water storage box 10. The bottom of the water storage box 10 is connected to the detection cover 3 through a water delivery pipe 12. The water delivery pipe 12 is a rigid pipe, which can not only support the water storage box 10 but also play the role of transporting clean water. A valve 13 is installed on the water delivery pipe 12. By opening the valve 13, the water delivery pipe 12 can be made unobstructed to transport clean water into the detection cover 3.

[0023] Specifically, by setting up the water storage box 10, the water delivery pipe 12, the valve 13, the piston plate 5 and the magnetic cover 4, when not in use daily, the magnetic cover 4 can be used to close the detection cover 3 to protect the plasticine block 7 and prevent dust from entering the detection cover 3 and adhering to the surface of the plasticine block 7. By injecting clean water into the water storage box 10 and then opening the valve 13, the clean water enters the detection cover through the water delivery pipe 12 and flows down through the small holes on the piston plate 5 to the plasticine block 7, enabling the plasticine block 7 to replenish the lost moisture. Compared with the prior art, on the one hand, using the magnetic cover 4 can achieve the purpose of dust-proofing the plasticine block 7. On the other hand, the detection cover 3 can be closed to avoid the plasticine block 7 being exposed to the air, thereby reducing the moisture loss of the plasticine block 7, extending the service life of the plasticine block 7. At the same time, by regularly replenishing water to the plasticine block 7 through the water storage box 10 and the water delivery pipe 12, the plasticine block 7 can maintain its original characteristics and facilitate normal use.

[0024] The piston plate 5 is a porous piston plate, which enables the clean water to fully diffuse so that the clean water can contact different positions on the plasticine block 7, thereby fully wetting the plasticine block 7. A base 20 is movably provided on the side of the column 1. A leveling and recording plate 21 is installed at the center of the base 20. A plurality of cameras are embedded in the middle of the leveling and recording plate 21, and a transparent plate for isolating the cameras is fixed on the leveling and recording plate 21.

[0025] Furthermore, an assembly block 17 is fixed on the column 1. A connecting seat 18 is movably installed on the assembly block 17. A telescopic rod 19 with a movable end movably connected to the base 20 is installed on the connecting seat 18.

[0026] Specifically, the end of the connecting seat 18 is connected to the assembly block 17 through a rotating shaft, and the connecting seat 18 is locked to the assembly block 17 through bolts. After determining the shape of the bubble, the bolts are removed, and the connecting seat 18 is rotated to make the base 20 rotate downward so that the leveling and recording plate 21 is parallel to the plasticine block 7 for the camera to record the shape of the bubble. Then, by adjusting the telescopic rod 19, the leveling and recording plate 21 is moved closer to the plasticine block 7 until the leveling and recording plate 21 closely adheres to the plasticine block 7, thereby leveling the plasticine block 7 for the next use.

[0027] Furthermore, studs 6 are evenly fixed on the piston plate 5, and the plasticine block 7 is inserted on the studs 6. The length of the studs 6 is less than the thickness of the plasticine block 7, so as to facilitate the replacement of the plasticine block 7.

[0028] Furthermore, the stud 6 is a hollow tube body and penetrates through the piston plate 5. The stud 6 is used to assist in transporting clear water into the plasticine block 7 to quickly moisten the plasticine block 7.

[0029] Furthermore, a bracket 14 is installed on the side of the column 1 away from the water storage box 10. A brake wheel 15 is installed at the bottom of the bracket 14, and a push rod 16 is installed on the detection cover 3.

[0030] Specifically, the bottom of the brake wheel 15 and the bottom of the magnetic attraction cover 4 are on the same plane. During actual use, the push rod 16 can be held to tilt the whole device towards the side close to the push rod 16, so that only the brake wheel 15 touches the ground, in order to move the device to detect concrete slabs at various places on the construction site.

[0031] Specifically, first place the concrete slab to be detected on the ground below the detection cover 3, then rotate the screw rod 2 to make the plasticine block 7 fit tightly downward with the concrete slab. After the bubbles are formed, take away the concrete slab and move the base 20 to place the leveling and recording board 21 below the plasticine block 7 to record the shape of the bubbles.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
