[0001] The present invention relates to the technical field of detection devices, in particular to a quality detection device and a detection method thereof for concrete construction. Background Art
[0002] In the current field of concrete construction technology, ensuring the compactness and overall quality of concrete structures is a key link in improving building safety and durability. Traditionally, in order to detect and improve the quality of concrete, a construction quality detection device based on the vibration principle is used. The device usually relies on a single vibration source, such as a vibrating rod or a vibrating plate, which is directly inserted or attached to the concrete surface for vibration to promote the discharge of bubbles inside the concrete and the close arrangement of particles. However, this existing technology has several significant defects: Uneven vibration effect: Since the vibration source is fixed or moved in a single way, it is difficult to achieve uniform and effective vibration in all areas of the concrete, especially inside large or complex structures. This often leads to insufficient compactness of the concrete in some parts and over-vibration in other parts, affecting the overall uniformity and mechanical properties. Limited vibration depth: For deeper concrete pouring layers, traditional vibration equipment is difficult to effectively penetrate to the bottom layer, making it difficult to completely remove the bubbles in the bottom concrete, reducing the overall density and strength of the concrete.

This vibration effectively promotes the rise and elimination of bubbles in the concrete, thereby significantly improving the compactness and overall quality of the concrete. The three sets of knocking rods on the support frame and the sliding installation of the knocking rods on the support frame can accurately control the vibration position to ensure uniform knocking and vibration of the upper, middle and lower positions of the cylinder, further improving the uniformity and density of the concrete.
[0014] The driving assembly drives the support frame to rotate in a circle, thereby driving the knocking rod to knock and vibrate the outer wall of the cylinder, and the vibrating rod to perform reciprocating vibration movement in the cylinder. The dual action effectively eliminates bubbles in the concrete and significantly improves the density and overall quality of the concrete. The entire device adopts a mechanized design. Through mechanical principles such as drive motor, gear ring meshing, bevel gear transmission, and synchronous belt pulley transmission, the automatic operation of knocking and vibrating is realized, which greatly reduces the complexity and labor intensity of manual operation and improves construction efficiency. The first slide bar, positioning wheel, limit plate and other structures ensure the precise sliding and positioning of the knocking rod. At the same time, by adjusting the meshing state of the half gear and the tooth plate, the frequency and amplitude of the vibration can be flexibly controlled to meet the requirements of different construction scenes and concrete performance. Through mechanized knocking and vibration treatment, the density of the concrete has been significantly improved, thereby ensuring the quality and strength of the concrete structure. At the same time, precise vibration control also ensures the uniformity and consistency of the concrete, improving the overall construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0018] Embodiment 1: Combination Figure 1-Figure 8As shown, the present invention provides a technical solution: a quality inspection device for concrete construction, comprising a base plate 1 and a cylinder 2, a fixed plate 11 is fixedly installed on the top of the base plate 1, and the cylinder 2 is located on the fixed plate 11, and the cylinder 2 is a structure formed by splicing two left and right half cylinders, in order to realize the splicing of the two half cylinders, cylinders are arranged on both sides of the fixed plate 11, and these cylinders are used to push the two half cylinders for splicing operation, a support frame 3 is arranged on one side of the cylinder 2, and a control component 5 is installed on the support frame 3, and the function of the control component 5 is to knock and vibrate the upper, middle and lower positions of the cylinder 2 to achieve the purpose of eliminating bubbles in the concrete and improving the compactness of the concrete, a first gear ring 12 is fixedly connected to the outer wall of the fixed plate 11, and a second gear ring 13 fixedly installed on the base plate 1 is arranged on the outer side of the first gear ring 12; A circular groove 14 and a first reciprocating groove 15 are provided on the surface of the bottom plate 1. The circular groove 14 is located inside the first reciprocating groove 15. Such a design helps to achieve specific mechanical movement and function. The control assembly 5 includes a driving assembly 51 installed at the bottom of the support frame 3. Three groups of knocking rods 56 are arranged above the driving assembly 51. Each group of knocking rods 56 includes two knocking rods. The knocking rods 56 are slidably installed on the support frame 3 to facilitate accurate knocking and vibration operations. The outer end of each knocking rod 56 is fixedly connected to a connecting plate 57. The upper and lower ends of the connecting plate 57 are slidably connected to a positioning rod 58. The positioning rod 58 is fixedly installed on the support frame 3. The outer side of the connecting plate 57 is provided with a second damping spring 59 sleeved on the positioning rod 58, which is used to provide buffering and rebound force during the knocking process. The bottom of the connecting plate 57 is fixedly connected with a movable rod 513, and the movable rod 513 is slidably installed in the first reciprocating groove 15. When the driving component 51 drives the support frame 3 to rotate in a circle, since the movable rod 513 is slidably installed in the first reciprocating groove 15, when the movable rod 513 is driven to move outward, it can drive the connecting plate 57 and the knocking rod 56 to move outward and compress the second damping spring 59. As the support frame 3 continues to rotate, under the elastic force of the second damping spring 59, the connecting plate 57 and the knocking rod 56 are pushed to move inward, so that the knocking rod 56 knocks and vibrates the outer wall of the cylinder 2. This vibration treatment causes the bubbles in the concrete to move upward and be eliminated, thereby significantly improving the compactness and overall quality of the concrete. At the upper, middle and lower positions of the support frame 3, a first slide bar 52 is connected to the support frame 3 for transverse sliding. A positioning wheel 53 is provided at the inner end of the first slide bar 52 to ensure the accuracy of sliding. A limit plate 54 is fixedly connected to the outer wall of the first slide bar 52. The limit plate 54 is located at the middle position of the support frame 3. In order to further ensure the stability of sliding, a first damping spring 55 sleeved on the knocking rod 56 is also provided at the outer end of the limit plate 54. The driving assembly 51 includes a driving motor 510 fixedly mounted on the supporting frame 3, and the output end of the driving motor 510 is fixedly connected to a first gear 511 meshing with the second gear ring 13. In order to ensure the stability of the transmission, two second slide bars 512 fixedly mounted on the first gear 511 are arranged on both sides of the first gear 511. The two second slide bars 512 are slidably mounted in the circular groove 14, ensuring smooth and accurate sliding. By turning on the driving motor 510, the first gear 511 can be driven to rotate synchronously. Since the first gear 511 is meshing with the second gear ring 13, and the second slide bar 512 is slidably mounted in the circular groove 14, the supporting frame 3 is driven to rotate in a circle on the bottom plate 1, thereby realizing accurate positioning and motion control. The inner side end of the support frame 3 is rotatably connected to four groups of vertical rods 515 through the shaft seat. These vertical rods 515 play an important supporting role in the movement of the support frame 3. At the same time, the outer wall of the support frame 3 is rotatably connected to a first bevel gear 514 sleeved on the first slide bar 52. In order to achieve the continuity of transmission, the upper and lower ends of the first bevel gear 514 are meshed and connected to a second bevel gear 516, and the second bevel gear 516 is fixedly connected to the vertical rod 515, ensuring the stability of the transmission. The bottom of the vertical rod 515 is A second gear 530 is fixedly connected to the bottom of the vertical rod 515, and the second gear 530 is meshed with the positioning wheel 53. When the driving assembly 51 drives the support frame 3 to rotate, the vertical rod 515 can be driven to rotate synchronously. Since the second gear 530 at the bottom of the vertical rod 515 is meshed with the first gear ring 12, the vertical rod 515 can be driven to rotate. Through the meshing of the first bevel gear 514 and the second bevel gear 516, the remaining vertical rods 515 can be driven to rotate synchronously, ensuring the coordination and stability of the entire system; At the upper part of the support frame 3, there is a rotatably connected spline rod 519, which shares the same axis with the fixed disk 11 in the vertical direction. The spline rod 519 is connected to the vertical rod 515 through a synchronous pulley transmission assembly 520 to achieve a transmission connection. The outer wall of the spline rod 519 is sleeved with a fixed plate 521 fixedly mounted on the support frame 3, and a rectangular rod 524 is fixedly connected to the bottom of the fixed plate 521. A sleeve rod 525 is slidably connected to the rectangular rod 524, and the outer end of the sleeve rod 525 is fixedly connected to a vibrating rod 527. The bottom of the spline rod 519 is fixedly connected to a cylinder 522, and a second reciprocating groove 523 is opened on the outer wall of the cylinder 522. The inner end of the sleeve rod 525 is fixedly connected to a guide rod 526, and the inner end of the guide rod 526 is slidably mounted in the second reciprocating groove 523. When the vertical rod 515 rotates, the spline rod 519 is driven to rotate through the synchronous belt pulley transmission assembly 520, and the spline rod 519 drives the cylinder 522 to rotate synchronously. During the rotation process, the spline rod 519 drives the sleeve rod 525 and the vibrating rod 527 to move up and down on the rectangular rod 524 through the second reciprocating groove 523 and the guide rod 526. Under the guidance of the rectangular rod 524, the vibrating rod 527 can move smoothly in the vertical direction. This up and down reciprocating movement mode enables the vibrating rod 527 to effectively vibrate the concrete in the cylinder 2. Through this mechanical vibration, the density of the concrete is significantly improved, thereby ensuring the quality and strength of the concrete structure. The whole process not only improves the work efficiency, but also ensures the construction quality, making the concrete pouring process more efficient and reliable. The top of the vertical rod 515 is fixedly connected to the half gear 531, and one side of the half gear 531 is meshedly connected to the tooth plate 517. The outer side of the tooth plate 517 is fixedly connected to the inclined plate 518 slidably installed on the support frame 3. A return spring is provided on one side of the inclined plate 518. The return spring is used to push the inclined plate 518 to move to the side away from the top plate 528. The top of the spline rod 519 is rotatably connected to the top plate 528, and the bottom of the top plate 528 is slidably connected to the inclined plate 518. One side of the top plate 528 is fixedly connected to the L-shaped slide bar 529. The L-shaped slide bar 529 is slidably installed on the support frame 3 in the vertical direction. When the vertical rod 515 rotates, it drives the half gear 531 to rotate, so that the half gear 531 drives the meshed tooth plate 517 and the inclined plate 518 to move toward the side of the top plate 528 during the rotation process. In this way, the inclined plate 518 pushes the top plate 528 and the L-shaped slide bar 52 9. The cylinder 522 moves upward, so that the cylinder 522 cooperates with the second reciprocating groove 523 to drive the guide rod 526, the sleeve rod 525, and the vibrating rod 527 to move upward. When the half gear 531 is no longer engaged with the tooth plate 517, the L-shaped slide bar 529 and the top plate 528 drive the spline rod 519, the cylinder 522, the guide rod 526, the sleeve rod 525, and the vibrating rod 527 to move downward under the action of their own gravity. This reciprocating movement enables the vibrating rod 527 to achieve continuous vibration of the concrete to ensure the uniformity and density of the concrete. During the vibration process, the up and down movement of the vibrating rod 527 is precisely guided by the guide rod 526 and the sleeve rod 525 to ensure the linearity and stability of the vibration. In addition, by adjusting the meshing state of the half gear 531 and the tooth plate 517, the frequency and amplitude of the vibration can be controlled to ensure the subsequent detection of the slump height of the concrete.
[0019] In the embodiment of the present invention, by starting the driving motor 510, the motor can drive the first gear 511 to rotate synchronously, the first gear 511 is tightly meshed with the second gear ring 13, and the second sliding rod 512 is slidably installed in the circular groove 14. Such a design enables the support frame 3 to rotate in a circle on the bottom plate 1. At the same time, the movable rod 513 is slidably installed in the first reciprocating groove 15. When the movable rod 513 moves outward, it can drive the connecting plate 57 and the knocking rod 56 to move outward and compress the second damping spring 59. With the continuous rotation of the support frame 3, under the elastic force of the second damping spring 59, the connecting plate 57 and the knocking rod 56 are pushed to move inward, so that the knocking rod 56 knocks and vibrates the outer wall of the cylinder 2. This vibration treatment helps to move the bubbles in the concrete upward and eliminate them, thereby improving the compactness of the concrete. At the same time, during the rotation of the support frame 3, the vertical rod 515 can be driven to rotate synchronously, and the second gear 530 at the bottom of the vertical rod 515 is meshed with the first gear ring 12, thereby driving the vertical rod 515 to rotate. Through the cooperation of the first bevel gear 514 and the second bevel gear 516, the remaining vertical rods 515 can be driven to rotate synchronously. When the vertical rod 515 rotates, the spline rod 519 is driven to rotate through the synchronous pulley transmission assembly 520, and the spline rod 519 then drives the cylinder 522 to rotate synchronously. During the rotation of the spline rod 519, the sleeve rod 525 and the vibrating rod 527 are driven to move up and down on the rectangular rod 524 through the second reciprocating groove 523 and the guide rod 526. Under the guidance of the rectangular rod 524, the vibrating rod 527 can move smoothly in the vertical direction. This up and down reciprocating motion mode enables the vibrating rod 527 to effectively vibrate the concrete in the cylinder 2. Through this mechanical vibration, the density of concrete is significantly improved, thereby ensuring the quality and strength of the concrete structure. The whole process not only improves work efficiency, but also ensures construction quality, making the concrete pouring process more efficient and reliable. In addition, the vertical rod 515 drives the half gear 531 to rotate when rotating, so that the half gear 531 drives the meshing tooth plate 517 and the inclined plate 518 to move toward the side of the top plate 528 during the rotation process, and the inclined plate 518 pushes the top plate 528, the L-shaped sliding rod 529, and the cylinder 52 2 moves upward, so that the cylinder 522 cooperates with the second reciprocating groove 523 to drive the guide rod 526, the sleeve rod 525, and the vibrating rod 527 to move upward. When the half gear 531 is no longer engaged with the tooth plate 517, the L-shaped sliding rod 529 and the top plate 528 drive the spline rod 519, the cylinder 522, the guide rod 526, the sleeve rod 525, and the vibrating rod 527 to move downward under the action of their own gravity. In this way, the vibrating rod 527 can continuously vibrate the concrete to ensure the uniformity and density of the concrete. During the vibration process, the up and down movement of the vibrating rod 527 is precisely guided by the guide rod 526 and the sleeve rod 525, ensuring the linearity and stability of the vibration. In addition, by adjusting the meshing state of the half gear 531 and the tooth plate 517, the frequency and amplitude of the vibration can be controlled, thereby ensuring the subsequent detection of the slump height of the concrete. This precise control and adjustment mechanism makes the concrete construction process more scientific and precise, and further improves the overall performance and reliability of the concrete structure.
[0020] The present invention also discloses a method for detecting the quality of concrete construction, which specifically comprises the following steps: Step 1: Use the cylinder to push the two half cylinders to splice to form the cylinder 2, put the concrete to be tested into the cylinder 2, and when the driving component 51 drives the support frame 3 to rotate in a circle, the support frame 3 moves back and forth through the movable rod 513, the connecting plate 57, and the second damping spring 59, thereby driving the knocking rod 56 to knock and vibrate the outer wall of the cylinder 2; Step 2: When the driving assembly 51 drives the support frame 3 to rotate, it can drive the vertical rod 515 to rotate synchronously. When the vertical rod 515 rotates, the spline rod 519 is driven to rotate through the synchronous belt pulley transmission assembly 520. The spline rod 519 drives the cylinder 522 to rotate synchronously. During the rotation process, the spline rod 519 drives the sleeve rod 525 and the vibrating rod 527 located on the rectangular rod 524 to move up and down through the second reciprocating groove 523 and the guide rod 526. Under the guidance of the rectangular rod 524, the vibrating rod 527 can move smoothly in the vertical direction, so that the vibrating rod 527 can effectively vibrate the concrete in the cylinder 2. Step 3: After the concrete in the cylinder 2 is vibrated, the cylinder 522 and the vibrating rod 527 are moved to the top of the cylinder 2, and then the two half cylinders are pushed open by the cylinder, the concrete collapses, and then the height of the concrete is measured to calculate the collapse degree of the concrete.

9. A detection method for a quality detection device for concrete construction as claimed in any one of claims 1 to 8, characterized in that: The specific steps include: Step 1: using a cylinder to push two half cylinders to be spliced together to form a cylinder body (2), and putting the concrete to be tested into the cylinder body (2). When the driving component (51) drives the support frame (3) to rotate in a circle, the support frame (3) moves back and forth through the movable rod (513), the connecting plate (57), and the second damping spring (59), thereby driving the knocking rod (56) to knock and vibrate the outer wall of the cylinder body (2); Step 2: When the driving assembly (51) drives the support frame (3) to rotate, it can drive the vertical rod (515) to rotate synchronously. When the vertical rod (515) rotates, the spline rod (519) is driven to rotate through the synchronous belt pulley transmission assembly (520). The spline rod (519) drives the cylinder (522) to rotate synchronously. During the rotation process, the spline rod (519) drives the sleeve rod (525) and the vibrating rod (527) located on the rectangular rod (524) to move up and down through the second reciprocating groove (523) and the guide rod (526). Under the guidance of the rectangular rod (524), the vibrating rod (527) can move smoothly in the vertical direction, so that the vibrating rod (527) can effectively vibrate the concrete in the cylinder (2); Step 3: After the concrete in the cylinder (2) is vibrated, the cylinder (522) and the vibrating rod (527) are moved to the top of the cylinder (2), and then the two half cylinders are pushed open by the cylinder, so that the concrete collapses. The height of the concrete is then measured, and the collapse degree of the concrete is calculated.
