Description

Technical Field

[0001] The invention relates to the technical field of roughness measurement, in particular to a device for measuring the roughness of a chiseled concrete surface and a method thereof. Background Art

[0002] Concrete roughening refers to the process of using chisels, pneumatic picks or roughening machines to remove the hardened skin on the surface of concrete to form a rough surface with a certain depth and spacing in order to make the new and old concrete bond well. The purpose of roughening is to increase the roughness of the concrete surface, thereby improving its adhesion with other materials and ensuring the stability and durability of the structure.

[0003] The purpose of measuring the roughness of the chiseled concrete surface is to quantify the degree of surface unevenness and provide data support for evaluating the bonding performance, anti-slip performance and aesthetics of the concrete surface.

[0004] At present, the roughness of concrete surface is usually measured by a roughness meter. For example, the concrete surface roughness measuring device and its measuring method disclosed in publication number CN106225654A use the common stylus roughness meter for measurement. The difference is that compared with the current direct handheld use, it adds a bracket to improve the stability of detection.

[0005] However, when such roughness meters are used handheld for measurement, they are easily affected by jitter factors, resulting in inaccurate test data. Using a bracket as shown in the above technology only improves stability, but if the speed is uneven when pushing, it will also affect the test data. The force when pushing is also likely to cause the device to shake. In addition, such roughness meters will cause varying degrees of wear on both the stylus and the concrete surface. The former affects the service life and detection accuracy of the device, and the latter will result in the inability to accurately obtain the roughness of the concrete surface itself, but the roughness after being scratched. Therefore, it is difficult for current roughness meters to obtain accurate test data. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 12 The present invention discloses a device for measuring the roughness of a chiseled concrete surface and provides the following four technical solutions: The first implementation method includes: The measuring instrument assembly 1 is configured to detect the roughness by contacting the chiseled surface of the concrete with the detection end and moving the detection end to detect the roughness; The track assembly 2 is used to guide the linear movement of the measuring instrument assembly 1, and the track assembly 2 can be folded and stored; A traction assembly 3, used for traction of the measuring instrument assembly 1 to move along the track assembly 2; The storage assembly 4 is used to store the measuring instrument assembly 1, the track assembly 2 and the traction assembly 3, and the storage assembly 4 controls the measuring instrument assembly 1 and the traction assembly 3; The measuring instrument assembly 1 is provided with two groups of measuring components for simultaneous measurement to reduce errors. The measuring instrument assembly 1 is detachably mounted on the track assembly 2, and the measuring instrument assembly 1 is connected to the detachable traction assembly 3. The traction assembly 3 and the storage assembly 4 are separately arranged. The track assembly 2 is placed on a horizontal plane or a vertical plane to guide the track assembly 2 to detect the ground or the vertical plane.

[0025] The storage assembly 4 includes a storage box 42, and the storage box 42 is divided into a machine compartment and a storage compartment. The electrical components are installed in the machine compartment, and a control panel 43 is arranged on the top of the machine compartment. A box cover 41 is hinged at the bottom of the storage compartment.

[0026] The track assembly 2 is used to provide a smooth moving track for the measuring instrument assembly 1, and the traction assembly 3 is used to provide a uniform drive. The traction assembly 3 is designed to be independently split, and its vibration will not affect the track assembly 2 and the measuring instrument assembly 1, reducing the interference of external factors on the measuring process of the measuring instrument assembly 1. At the same time, the measuring instrument assembly 1 can perform two groups of detections on the same track at the same time, and the mutual comparison further improves the accuracy of the detection data. Compared with the direct handheld roughness meter mobile detection, its accuracy is higher, and the device can meet the detection of concrete surfaces at different angles, with strong adaptability, and each part of the structure is detachable or foldable, which is easy to carry.

[0027] The second embodiment is mainly different from the first embodiment in that the measuring instrument assembly 1 includes a quick-install component and a measuring component, the measuring component is installed on the track assembly 2 through the quick-install component, and the measuring component includes: A right-angle mounting frame 11, which is rotatably mounted on the quick-install component and fastened by a fastening bolt 12; Two guide tubes 13 are fixedly connected to the bottom of the right-angle mounting frame 11; A lightweight probe rod 14 is slidably disposed inside the guide tube 13, and the bottom end of the lightweight probe rod 14 extends out of the guide tube 13. The lightweight probe rod 14 slides down by its own weight to contact the detection surface, and the bottom end of the lightweight probe rod 14 is wear-resistant and replaceable; Two groups of infrared distance measuring sensors 15 are fixedly connected to the top of the right-angle mounting frame 11, and the infrared distance measuring sensors 15 are used to measure the distance change at the top of the lightweight probe rod 14, and the distance change value is represented by a waveform diagram.

[0028] The lightweight probe rod 14 includes a light main pipe 141, the top of which is connected to a slider 142, which is slidably arranged inside the guide tube 13, and the side of the slider 142 is provided with an airflow groove for airflow at both ends to pass through when the slider 142 slides axially in the guide tube 13. The airflow groove can prevent the slider 142 from moving slowly due to airflow obstruction when sliding axially. A wear-resistant head 143 is inserted at the bottom end of the light main pipe 141, and a rubber plug that elastically engages the wear-resistant head 143 is provided at the inner bottom end of the light main pipe 141, and the rubber plug can improve the stability of the insertion of the wear-resistant head 143.

[0029] The quick-install component includes a U-shaped sleeve 16 and a side plate 17 for sleeved on the outside of the track assembly 2. The side plate 17 is installed at the open end of the U-shaped sleeve 16 to form a complete frame. The upper and lower surfaces of the U-shaped sleeve 16 are provided with positioning sleeves 113. The four corners of one side of the side plate 17 are provided with metal springs 18 that are inserted into and engaged with the positioning sleeve 113. The end of the metal spring 18 is bent, and the bending height is greater than the inner height of the positioning sleeve 113. During the insertion process, the metal spring 18 is deformed and passed through, and rebounds after passing through to clamp the positioning sleeve 113. A winding column 19 is arranged in the middle of the top of the U-shaped sleeve 16 , and a ring groove 191 is opened on the side of the winding column 19 , and a rubber ring 192 is embedded in the ring groove 191 , and the rubber ring 192 can improve the anti-slip effect.

[0030] A positioning column 110 is provided on the other side of the side plate 17, which rotates through the right-angle mounting frame 11 and is threadedly connected to the fastening bolt 12. A non-slip rubber pad 111 is also adhered to the other side of the side plate 17. A magnetic ring 112 is embedded on the side of the right-angle mounting frame 11 close to the fastening bolt 12. The magnetic ring 112 magnetically attracts the fastening bolt 12 and does not protrude from the surface of the right-angle mounting frame 11. Non-protrusion can prevent the magnetic ring 112 from directly contacting the fastening bolt 12, thereby affecting the natural sagging of the right-angle mounting frame 11.

[0031] By utilizing the quick-release structure, the measuring instrument assembly 1 can be quickly assembled and disassembled by simply plugging and unplugging. The measuring instrument assembly 1 uses a lightweight probe rod 14 with a small dead weight to slide under gravity in the guide tube 13 for detection. At the same time, a wear-resistant head 143 that is easy to disassemble and replace and wear-resistant is provided at the bottom to contact the ground for detection, so that the friction between the wear-resistant head 143 and the ground is small, thereby reducing wear and tear. It is also easy to replace after severe wear and tear, and the ground will not cause obvious scratches, thereby ensuring the most accurate roughness measurement. Or, for the roughness detection needs of different detection surfaces, different wear-resistant heads 143 can be replaced, which is easy to use.

[0032] The third embodiment mainly differs from the first embodiment in that: the traction assembly 3 includes an active end bracket 31 and a driven end bracket 32, and both the active end bracket 31 and the driven end bracket 32 ​​include a vertical bracket 33 and a first bottom plate 34, the top of the inner side of the vertical bracket 33 is rotatably connected with a rubber wheel 35, and a transmission rope 36 is transmitted between the two rubber wheels 35, and a servo motor 37 for driving the rubber wheel 35 to rotate is installed on the side of the vertical bracket 33 of the active end bracket 31, and the power cord of the servo motor 37 is plugged into the corresponding socket outside the storage assembly 4, and the transmission rope 36 is wound in the ring groove 191 to connect the measuring instrument assembly 1; A magnetic disk 38 is disposed at the bottom of the first bottom plate 34 of the active end bracket 31, and a groove for accommodating and adsorbing the magnetic disk 38 is disposed at the top of the storage component 4. The engagement and magnetic attraction effect between the magnetic disk 38 and the groove facilitate the stable installation of the active end bracket 31 without manually pressing and stabilizing both ends.

[0033] The traction component 3 uses a ring-shaped transmission rope 36 to pull the measuring instrument component 1 to move. It can be connected to the measuring instrument component 1 by a simple winding and sleeve method, and the flexible traction structure can effectively eliminate the impact of the vibration of the traction component 3 itself on the measuring instrument component 1. By controlling the number of winding circles, the overall span of the traction component 3 can also be adjusted to meet the actual detection length range requirements.

[0034] The fourth embodiment mainly differs from the first embodiment in that: the track assembly 2 includes at least two sections of track square tubes 21, and the track square tubes 21 are connected by built-in pull-out connectors, and the pull-out connectors include two sections of sliding members 29 slidably arranged in the track square tubes 21, and a connecting block 22 is rotatably connected between the two sliding members 29, and a positioning spring piece 23 is fixedly connected to one side of the sliding member 29, and both ends of the positioning spring piece 23 are arched.

[0035] The track assembly 2 also includes vertical plates 25 arranged at both ends, and a rotating block 26 inserted into the track square tube 21 is fixed on one side of the vertical plate 25, and the rotating block 26 can be rotated 90 degrees downward in the track square tube 21 for storage, and a second bottom plate 27 is arranged at the bottom end of the vertical plate 25, and hanging plates 210 are hinged on both sides of the second bottom plate 27 through hinges. When the track assembly 2 is used upright, the hanging plates 210 are rotated to be perpendicular to the second bottom plate 27 and hung on the step surface; A support rib 39 is fixedly connected between the vertical bracket 33 of the driven end bracket 32 ​​and the side of the first base plate 34, a positioning rod 28 is provided at the outer bottom of the vertical plate 25, and a positioning hole 310 corresponding to the positioning rod 28 is opened inside the support rib 39, so that when the track assembly 2 is vertically hung on the step surface, the driven end bracket 32 ​​is attached to the track assembly 2 for installation.

[0036] The multi-section setting of the track component 2 can realize straight-line splicing or folding, and the overall length can be adjusted by controlling the number of spliced ​​sections, thereby adjusting the detection range. The foldable setting of the brackets at both ends of the track component 2 can further improve the storability, and one end of the track component 2 can be hung on the facade for detection by hanging. At this time, it can also cooperate with the driven end bracket 32 ​​of the traction component 3, and the driven end bracket 32 ​​is hung on one end of the track component 2, which is more convenient for the roughness detection of the facade.

[0037] The invention also discloses a method for measuring the roughness of a chiseled concrete surface, comprising the following steps: S1. Equipment preparation: first open the box cover 41 of the storage component 4, take out the measuring instrument component 1, the track component 2 and the traction component 3, straighten the track square tube 21 of the track component 2, and then push each other, push the connecting block 22 and the sliding member 29 into the track square tube 21, and make the positioning plate 24 clamp the positioning spring 23, then unfold and put the traction component 3, use the magnetic disk 38 to absorb the active end bracket 31 into the top groove of the storage box 42, and place the driven end bracket 32 ​​on the other end of the track square tube 21; then electrically connect the traction component 3 and the measuring instrument component 1 to the storage component 4, and then put the U-shaped sleeve 16 and the side plate 17 of the measuring instrument component 1 on the track square tube 2 1, insert the metal spring sheet 18 into the positioning sleeve 113, install the measuring instrument assembly 1 on the track assembly 2, and wind the transmission rope 36 of the traction assembly 3 into the ring groove 191 of the winding column 19 to connect the measuring instrument assembly 1, and then adjust the angle of the measuring component of the measuring instrument assembly 1. When testing on the ground, keep the testing direction of the measuring component vertically downward. At this time, the fastening bolt 12 can be loosened, and the magnetism of the magnetic ring 112 can be used to bring the right-angle mounting frame 11 out for a section to make it separate from the anti-slip rubber pad 111, so that the value can be kept drooping under gravity.
