[0001] The present invention relates to the technical field of slurry detection, and in particular to a device and method for detecting concrete grouting material in a prefabricated component. Background Art

[0002] Prefabricated reinforced concrete structures have been widely used in practice and have relatively mature technical research in developed countries such as Europe, America, and Japan. Compared with traditional cast-in-place concrete, prefabricated reinforced concrete structures can reduce manual labor and wet work on site, have fast construction speed, and have little impact on the surrounding environment. The quality of prefabricated components is easy to control, and the overall construction quality of the project is easier to guarantee. With the research and vigorous promotion of prefabricated and assembled concrete buildings in my country, prefabricated concrete structures have made great progress in my country.

[0003] In order to detect the quality problems of concrete grouting materials in prefabricated components, a variety of detection methods are currently used. Among them, core drilling detection is a destructive detection method. Samples are drilled in concrete components and the samples are tested in the laboratory to evaluate the quality and strength of concrete. However, when the operator is drilling the core, the operator holds the core drilling device. During the core drilling process, strong vibrations will be generated, which will cause the core drilling direction to change when the operator holds the core drilling device, and then cause the sampling position to change from the pre-set sampling position, and the sampling size will also change, affecting the detection results.

[0013] Preferably, the cross section of the connecting pipe is cross-shaped, and the push pipe is vertically connected to the connecting pipe.

[0014] An inspection method using the concrete grouting material detection device in the prefabricated component, the steps are as follows:

[0015] S1: Rotate the rotating seat to adjust the sampling angle, start the first hydraulic rod and the sampling assembly to take samples;

This method of replacing the operator's handheld device for core sampling can avoid the core drilling direction being changed when the operator holds the core drilling device during the core drilling process, thereby causing the sampling position to change from the preset sampling position, and the sampling size also changes, affecting the detection result.

[0021] After the sample is clamped, the second hydraulic rod is started, and the second hydraulic rod drives the rotating frame to move downward through the connecting block, and the rotating frame drives the sample to move through the lower clamp and the upper clamp; thereby saving the operator the operation of transporting the sample, reducing the operation and improving the efficiency on the one hand, and avoiding damage to the sample during the transportation process on the other hand.

[0022] The present invention can make the sample start to rotate after moving down a certain position, so that one end of the sample gradually moves into the interior of the detection groove. During the rotation of the sample, the sample will contact and be squeezed by the squeezing ball. Since the position of the squeezing ball does not change, during the process of the sample rotating and gradually entering the interior of the detection groove, the squeezing ball performs squeezing detection on various parts of the sample to determine the pressure condition of the sample. On the one hand, it is different from the detection method of a single position of the sample. This method detects the position comprehensively and improves the inspection effect of the sample. On the other hand, it automatically detects various parts of the sample, which greatly improves the efficiency of the detection work. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0033] The present invention provides a detection device and a detection method for concrete grouting material in a prefabricated component, comprising a fixed frame 1 standing on the ground, a core sampling mechanism 2 for automatically positioning core drilling sampling is arranged on the fixed frame 1, a sample detection mechanism 3 for collecting and detecting samples in cooperation with the core sampling mechanism 2 is arranged on the fixed frame 1, the core sampling mechanism 2 comprises a rotating seat 21 rotating on the fixed frame 1, a sampling assembly for core drilling is arranged on the rotating seat 21, a side plate 24 rotating synchronously with the rotating seat 21 is arranged on one side of the rotating seat 21, a second hydraulic rod 25 is fixed on one side of the side plate 24, and the second hydraulic rod 25 is fixed on one side of the side plate 24. The output end of the rod 25 is rotatably provided with a rotating frame 29, on which an upper clamp 214 for clamping the sample is arranged below the sampling assembly, and a guide rod 28 is passed through the rotating frame 29, and a lower clamp 210 for receiving the sample is arranged below the upper clamp 214 on one end of the guide rod 28, and a scale rod 211 is passed through the other end of the guide rod 28; the fixed frame 1 is L-shaped, and a retractable support leg is arranged at the bottom of the fixed frame 1, and the rotating seat 21 is fixedly and rotatably connected with the fixed frame 1, (the fixed rotation connection method refers to a method that can simultaneously realize fixation and rotation Functional connection method. In manufacturing, the fixed rotation connection method is widely used in the connection of various machines and equipment, such as automotive parts, aerospace equipment, industrial robots, etc. The principle of the fixed rotation connection method is to rely on certain mechanical design principles to achieve the simultaneous fixing and rotation functions. For example, in the design of machine parts, the dual effects of normal force and tangential force are usually adopted, and structures such as flanges and boss teeth are designed to achieve high-strength and high-precision fixing and rotation functions) The first hydraulic rod 22 is fixedly arranged on the rotating seat 21, and the sampling assembly is arranged The sampling assembly includes a motor 23 and a sampling drill 27, one end of the side plate 24 is fixedly mounted on the rotating seat 21, the second hydraulic rod 25 is fixedly mounted on the side plate 24, a connecting block 213 is fixedly mounted on the output end of the second hydraulic rod 25, one end of the rotating frame 29 is unidirectionally rotatably arranged on the connecting block 213, a fastening bolt is arranged on one side of the upper chuck 214, the guide rod 28 is damped and slidable on the rotating frame 29, the scale rod 211 is damped and slidable on the other side of one end of the guide rod 28, and sliding rods 212 are arranged at both ends of the lower chuck 210;

[0034] See also Figures 1 to 5As shown, when sampling, by rotating the rotating seat 21 on the fixed frame 1, the rotating seat 21 drives the first hydraulic rod 22 to rotate, and the first hydraulic rod 22 also drives the sampling assembly to rotate. After rotating to the preset drilling angle, the motor 23 is started, and the output end of the motor 23 drives the sampling drill bit 27 to work, and the concrete grouting material sample in the prefabricated component is drilled by the sampling drill bit 27. In addition, while the rotating seat 21 rotates, the rotating seat 21 drives the side plate 24 to rotate, and the side plate 24 drives the second hydraulic rod 25 to rotate. The second hydraulic rod 25 drives the output end to drive the rotating frame 29 to rotate through the connecting block 213, and the rotating frame 29 drives the upper chuck 214 to rotate synchronously with the sampling drill bit 27. After adjusting the sampling angle, the lower chuck 210 can be rotated The rotating frame 29 rotates on the connecting block 213 to avoid the lower chuck 210 being located below the upper chuck 214, which causes the upper chuck 214 to be unable to contact the core drilling surface, and further the sampling drill bit 27 cannot pass through the upper chuck 214. Therefore, when the sampling drill bit 27 is used for core drilling sampling, the sampling drill bit 27 can first be made to contact the core drilling surface to play a positioning role, which can assist in core drilling accuracy and improve the accuracy of core drilling sampling. This method of core drilling sampling instead of the operator holding the device avoids strong vibration during the core drilling process, which will cause the core drilling direction to change when the operator holds the core drilling device, thereby causing the sampling position to change from the preset sampling position, and the sampling size also changes, affecting the detection result.

[0035] After the core sampling is completed, the rotating seat 21 rotates in the opposite direction to reset, and the lower chuck 210 is reset to the bottom of the upper chuck 214 by its own gravity. After the rotating seat 21 is reset, the sample slides down from the inside of the sampling drill bit 27, and the bottom contacts and squeezes the lower chuck 210 and continues to slide downward, and then the other end of the sample is fixed by the fastening bolts on the upper chuck 214. At this time, the operator can also assist in pressing one end of the sample against the lower chuck 210, and the other end is fixed by the fastening bolts on the upper chuck 214; after the sample is clamped, the second hydraulic rod 25 is started, and the second hydraulic rod 25 drives the rotating frame 29 to move downward through the connecting block 213, and the rotating frame 29 drives the sample to move through the lower chuck 210 and the upper chuck 214; thereby saving the operator the operation of transporting the sample, on the one hand reducing the operation and improving the efficiency, and on the other hand avoiding damage to the sample during transportation.

[0036] The sample detection mechanism 3 includes a detection slot 31 provided at the bottom of the fixed frame 1, a guide rail box 32 is provided on one side of the detection slot 31, a third hydraulic rod 34 is provided at the bottom of the fixed frame 1, the output end of the third hydraulic rod 34 passes through the bottom of the fixed frame 1 and is provided with a push tube 38, a push rod 35 is fixed to the output end of the push tube 38, and one end of the push rod 35 is provided with a squeezing ball 36 that squeezes the sample during the downward movement of the sample; a liquid storage tank 33 whose liquid outlet is connected to the detection slot 31 is provided on the fixed frame 1, and a connecting pipe 37 is connected to the liquid outlet of the liquid storage tank 33, and the other end of the connecting pipe 37 is connected to the detection slot 31, and the connecting pipe 37 is connected through and connected with the push tube 38, and a through hole 39 connected with the connecting pipe 37 is penetrated on the push tube 38; when the sliding rod 212 contacts the inclined surface of the guide rail box 32, it slides along the inclined surface, the cross section of the connecting tube 37 is a cross, and the push tube 38 is vertically connected with the connecting tube 37;

[0037] See also Figures 5 to 8 As shown, in addition, during the process that one end of the sample moves downward against the lower clamp 210, the lower clamp 210 drives the guide rod 28 and the scale rod 211 to move downward synchronously, and the guide rod 28 slides on the rotating frame 29; then the sample is fixed by the fastening bolts on the upper clamp 214; in addition, before the second hydraulic rod 25 drives the rotating frame 29 to move downward through the connecting block 213, the third hydraulic rod 34 is started, and the output end of the third hydraulic rod 34 drives the push tube 38 to move, the push tube 38 drives the push rod 35 to move, and the push rod 35 drives the squeezing ball 36 to move until the push rod 35 moves upward to contact with the scale rod 211, thereby setting the position of the squeezing ball 36, and after the second hydraulic rod 25 drives the rotating frame 29 to move downward through the connecting block 213, refer to Figure 5 as well as Figure 6 As shown, after the slide bar 212 on the lower clamp 210 contacts the inclined surface on the guide rail box 32, the inclined surface will guide the moving direction of the lower clamp 210, so that the lower clamp 210 rotates along the inclined surface and on the connecting block 213 through the rotating frame 29, and the upper clamp 214 rotates synchronously with the lower clamp 210 through the rotating frame 29, so that the sample can start to rotate after moving down to a certain position, so that one end of the sample gradually moves to the inside of the detection groove 31. During the rotation of the sample, the sample will contact and squeeze the squeezing ball 36. Since the position of the squeezing ball 36 does not change, during the process of the sample rotating and gradually entering the inside of the detection groove 31, the squeezing ball 36 performs squeezing detection on various parts of the sample to determine the pressure condition of the sample. On the one hand, it is different from the detection method of a single position of the sample. This method detects the position comprehensively and improves the inspection effect of the sample. On the other hand, it automatically detects various parts of the sample, which greatly improves the efficiency of the detection work.

[0038] In addition, according to the actual test requirements, refer to Figure 5As shown, the position of the scale rod 211 is adjusted according to the scale on the scale rod 211, so as to control the distance that the third hydraulic rod 34 drives the push rod 35 to move upward, thereby adjusting the position of the squeezing ball 36 and the pressure exerted on the sample by the squeezing ball 36 during the movement of the sample. Through the elastic design of the squeezing ball 36, the sample can be rotated while the squeezing ball 36 is being squeezed and detected. In addition, during the rotation of the sample, the squeezing ball 36 exerts different pressures on different parts of the sample, so the pressure detection of the sample within a certain pressure range can be detected, thereby improving the flexibility of pressure detection.

[0039] In addition, when the third hydraulic rod 34 drives the push tube 38 to move upward, the push tube 38 vertically penetrates the connecting tube 37 and moves upward. When the push tube 38 moves upward, the valve on the liquid outlet of the liquid storage tank 33 is opened. Figure 8 As shown, at this time, the solvent in the liquid storage tank 33 will enter the interior of the connecting pipe 37 through the liquid outlet, and enter the interior of the detection tank 31 through the through hole 39 on the push tube 38. After the sample rotates, it enters the interior of the detection tank 31 for durability testing, which can distinguish the durability test of the sample from the pressure test, further improve the inspection style of the sample, provide multiple sets of data, and improve the sample detection effect;

[0040] In addition, according to the arrangement pattern of the through holes 39 on the push tube 38, when the push tube 38 moves up a long distance, the through holes 39 on the push tube 38 are connected to the connecting tube 37 in more or less numbers according to actual requirements, thereby changing the flow rate of the solvent. In this way, the required amount of solvent can be automatically calculated according to actual requirements, reducing costs and avoiding the impact of excessive solvent use on the environment; at the same time, avoiding the use of too much or too little solvent during durability testing, resulting in waste of resources or affecting the detection effect.

[0041] An inspection method using a concrete grouting material detection device in a prefabricated component, the steps are as follows:

[0042] S1: Rotate the rotating seat 21 to adjust the sampling angle, start the first hydraulic rod 22 and the sampling assembly to perform sampling;

[0043] S2: After sampling, the rotating seat 21 is reset, and the sample falls off the sampling assembly and is clamped by the upper clamp 214 and the lower clamp 210;

[0044] S3: After the upper chuck 214 and the lower chuck 210 clamp the sample, the second hydraulic rod 25 is started. The second hydraulic rod 25 drives the sample to move downward and rotate along the inclined surface of the guide box 32. When the sample rotates and is squeezed by the squeezing ball 36, the sample is squeezed and detected;

[0045] S4: After the sample is rotated, it enters the detection tank 31 for durability testing.

[0046] Working principle: Sample sampling is carried out by rotating the rotating seat 21 on the fixed frame 1. The rotating seat 21 drives the first hydraulic rod 22 to rotate, and the first hydraulic rod 22 also drives the sampling component to rotate. After rotating to the preset drilling angle, the motor 23 is started, and the output end of the motor 23 drives the sampling drill bit 27 to work, and the concrete grouting material sample in the prefabricated component is drilled through the sampling drill bit 27.

[0047] Sample collection, the rotating seat 21 rotates in the opposite direction and resets, and the lower chuck 210 resets to the bottom of the upper chuck 214 by its own gravity. After the rotating seat 21 is reset, the sample slides down from the inside of the sampling drill bit 27, and the bottom contacts and squeezes the lower chuck 210 and continues to slide downward, and then the other end of the sample is fixed by the fastening bolts on the upper chuck 214. At this time, the operator can also assist in pressing one end of the sample against the lower chuck 210, and the other end is fixed by the fastening bolts on the upper chuck 214.

[0048] During sample testing, when one end of the sample moves downward against the lower chuck 210, the lower chuck 210 drives the guide rod 28 and the scale rod 211 to move downward synchronously, and the guide rod 28 slides on the rotating frame 29; then the sample is fixed by the fastening bolts on the upper chuck 214; in addition, before the second hydraulic rod 25 drives the rotating frame 29 to move downward through the connecting block 213, the third hydraulic rod 34 is started, and the output end of the third hydraulic rod 34 drives the push tube 38 to move, the push tube 38 drives the push rod 35 to move, and the push rod 35 drives the squeezing ball 36 to move, until the push rod 35 moves upward to contact the scale rod 211, thereby setting the squeezing ball 36. The second hydraulic rod 25 drives the rotating frame 29 to move downward through the connecting block 213, and the sliding rod 212 on the lower chuck 210 contacts the inclined surface on the guide rail box 32. The inclined surface will guide the moving direction of the lower chuck 210, so that the lower chuck 210 rotates along the inclined surface and on the connecting block 213 through the rotating frame 29, and the upper chuck 214 rotates synchronously with the lower chuck 210 through the rotating frame 29, so that the sample can start to rotate after moving down to a certain position, so that one end of the sample gradually moves to the inside of the detection slot 31. During the rotation of the sample, the sample will contact and squeeze the squeezing ball 36 to perform squeezing detection on various parts of the sample.

[0049] Secondary testing of samples: During the process of the third hydraulic rod 34 driving the push tube 38 to move upward, the push tube 38 moves vertically through the connecting tube 37. While the push tube 38 moves upward, the valve on the liquid outlet of the liquid storage tank 33 is opened. Figure 8 As shown, at this time, the solvent inside the liquid storage tank 33 will enter the interior of the connecting tube 37 through the liquid outlet, and enter the interior of the detection tank 31 through the through hole 39 on the push tube 38. After the sample rotates, it enters the interior of the detection tank 31 for durability testing.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
