Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a quality testing device and method for highway construction. Background Technology

[0002] During highway construction, testing devices are needed to inspect the quality of the highway and ensure the quality of the project. These devices typically inspect the concrete layer of the highway. However, with existing sampling devices, concrete samples tend to get stuck inside the sampling tube at the end of the sampling process, making them difficult to remove. Furthermore, the process of sampling concrete generates a large amount of dust, which can be harmful to the human body if inhaled and also damages the environment.

[0003] To address the above problems, patent document CN214277469U discloses a quality inspection device for highway bridge construction, comprising a handcart. The handcart has a vertically oriented mounting rail on its top, and a height-adjustable mounting plate is mounted on the rail. A sampling cylinder is mounted on the mounting plate, and a push plate is movably mounted inside the sampling cylinder. The handcart has a drive unit for raising and lowering the mounting plate, a water tank, and a nozzle connected to the water tank. In use, this technical solution facilitates movement by mounting the sampling cylinder on the handcart, allowing for convenient sampling of different areas. The push plate facilitates the ejection of samples stuck inside the sampling cylinder, and the nozzle sprays water onto the sampling area during sampling, effectively reducing dust.

[0004] However, the existing quality testing equipment used in highway construction requires workers to place the sample tube at the bottom of the sampling tube and then manually push the push plate to collect the concrete sample, which is not convenient to operate. Summary of the Invention

The mounting frame is mounted on the upper surface of the handcart, the height adjustment mechanism is mounted inside the mounting frame, the mounting plate is provided at the output end of the height adjustment mechanism, the drive motor is provided on the mounting plate, the sampling cylinder is provided at the output end of the drive motor, a push plate is slidably disposed inside the sampling cylinder, and push handles are provided on both sides of the push plate, the push handles extending to the outside of the sampling cylinder.

[0007] The sampling mechanism includes a mounting rail, a drive assembly, a sliding seat, a connecting arm, a sample cylinder, and a pushing assembly. The mounting rail is mounted on the upper surface of the trolley, and the sliding seat is slidably mounted on the mounting rail. The drive assembly is disposed inside the mounting rail, and its output end is connected to the sliding seat.

[0010] The pushing assembly includes a fixed arm, a driving member, and a sliding arm. One end of the fixed arm is connected to the bottom of the mounting plate, and the sliding arm is slidably disposed inside the other end of the fixed arm. The pushing ring is installed at the end of the sliding arm away from the mounting plate. Both the fixed arm and the sliding arm are hollow structures. The driving member is installed at the inner bottom of the fixed arm, and the output end of the driving member is connected to the inner bottom of the sliding arm.

The second ball screw nut assembly is connected to the inner bottom wall of the sliding arm.

[0012] The quality inspection device for highway construction also includes a protective plate. A through groove is provided on the sliding seat, and the protective plate is installed inside the through groove. The two ends of the protective plate are respectively connected to the two ends of the mounting guide rail.

[0013] The protective plate has connecting blocks on both sides at both ends. One end of the connecting block is connected to the side of the protective plate, and the other end of the connecting block is connected to the side of the mounting rail.

After concrete sampling is completed in the sampling cylinder, the height adjustment mechanism drives the mounting plate to reset, causing the sampling cylinder to return to the top of the mounting frame. The drive assembly drives the sliding seat to slide on the mounting guide rail, moving the sample cylinder below the sampling cylinder. Once the sample cylinder is below the sampling cylinder, the pushing assembly is activated, applying force to the pushing handle through the pushing ring, causing the pushing plate to slide downward inside the sampling cylinder, thereby pushing the concrete sample in the sampling cylinder into the sample cylinder, completing the collection of the concrete sample. Using this structure, the operation is more convenient when collecting concrete samples from the sampling cylinder. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] First embodiment:

[0032] Please see Figures 1 to 5 ,in Figure 1 This is a structural schematic diagram of the quality inspection device for highway construction according to the first embodiment. Figure 2 yes Figure 1 A magnified view of the local structure at point A. Figure 3 This is a structural schematic diagram of the quality inspection device for highway construction according to the first embodiment, from another perspective. Figure 4 yes Figure 3 A magnified view of the local structure at point B. Figure 5 This is a schematic diagram of the internal structure of the sampling tube in the first embodiment.

[0033] This invention provides a quality inspection device for highway construction: it includes a handcart 101, a mounting frame 102, a height adjustment mechanism 103, a mounting plate 104, a drive motor 105, a sampling cylinder 106, and a sampling mechanism. The sampling mechanism includes a mounting guide rail 107, a drive assembly, a sliding seat 108, a connecting arm, a sample cylinder 109, and a pushing assembly. The drive assembly includes a first servo motor 110, a first threaded rod 111, and a first ball screw nut assembly 112. The connecting arm includes an arm body 113, a fixing block 114, a mounting ring 115, and a locking bolt 116. The pushing assembly includes a fixed arm 117, a drive component, and a sliding arm 118. The drive component includes a second servo motor 119, a second threaded rod 120, and a second ball screw nut assembly 121. The aforementioned solution addresses the problem that existing quality testing devices for highway construction require workers to place the sample tube 109 at the bottom of the sampling tube 106 and then manually push the push plate 122 to collect concrete samples, which is inconvenient in actual use. It is understandable that the aforementioned solution can be applied to the structure of quality testing devices for highway construction.

[0034] In this specific embodiment, the mounting bracket 102 is mounted on the upper surface of the handcart 101. The height adjustment mechanism 103 is installed inside the mounting bracket 102. The output end of the height adjustment mechanism 103 is provided with the mounting plate 104. The drive motor 105 is mounted on the mounting plate 104. The output end of the drive motor 105 is provided with the sampling cylinder 106. A push plate 122 is slidably disposed inside the sampling cylinder 106. Push handles 123 are provided on both sides of the push plate 122. The push handle 123 extends to the outside of the sampling cylinder 106. When the sampling cylinder 106 is moved to the sampling area by the handcart 101, the height adjustment mechanism 103 is activated, which drives the mounting plate 104 to descend continuously. At the same time as the mounting plate 104 descends, the drive motor 105 is activated to drive the sampling cylinder 106 to rotate, thereby completing the sampling of concrete. Furthermore, the arrangement of the push handle 123 and the push plate 122 facilitates the extraction of concrete samples from the sampling cylinder 106.

[0035] The mounting rail 107 is mounted on the upper surface of the handcart 101. A sliding seat 108 is slidably mounted on the mounting rail 107. A driving assembly is housed inside the mounting rail 107, and its output end is connected to the sliding seat 108. One end of a connecting arm is connected to the upper surface of the sliding seat 108, and the other end of the connecting arm holds the sample cylinder 109. A pushing assembly is mounted on the bottom of the mounting plate 104, and its output end has a pushing ring 124. The pushing ring 124 is located outside the sampling cylinder 106 and above the pushing handle 123. After concrete sampling is completed in the sampling cylinder 106, the height adjustment mechanism 103 drives the... The mounting plate 104 is reset, causing the sampling cylinder 106 to return to the top of the interior of the mounting bracket 102. The driving assembly drives the sliding seat 108 to slide on the mounting guide rail 107, causing the sample cylinder 109 to move below the sampling cylinder 106. After the sample cylinder 109 moves below the sampling cylinder 106, the pushing assembly is activated. The pushing ring 124 applies force to the pushing handle 123, causing the pushing plate 122 to slide downward inside the sampling cylinder 106, thereby pushing the concrete sample in the sampling cylinder 106 into the sample cylinder 109, completing the collection of the concrete sample. With the above structure, the operation is more convenient when collecting the concrete sample in the sampling cylinder 106.

[0036] Secondly, the first servo motor 110 is installed inside the mounting guide rail 107. The output end of the first servo motor 110 is provided with the first threaded rod 111, and the first ball screw nut pair 112 is provided on the first threaded rod 111. The first ball screw nut pair 112 is connected to the sliding seat 108. When the first servo motor 110 is started, the first threaded rod 111 is driven to rotate. Since the first ball screw nut pair 112 is connected to the sliding seat 108, the sliding seat 108 is driven to slide on the mounting guide rail 107. A rotating head 125 is provided at the end of the first threaded rod 111 away from the first servo motor 110. A rotating bearing 126 is provided at the end of the mounting guide rail 107 away from the first servo motor 110. The rotating head 125 is embedded inside the rotating bearing 126.

[0037] Meanwhile, a fixing block 114 is fixedly provided at one end of the arm body 113, and a mounting ring 115 is fixedly provided at the other end of the arm body 113. A locking bolt 116 is provided on the side of the mounting ring 115. The sample cylinder 109 is installed inside the mounting ring 115 by the locking bolt 116. The fixing block 114 facilitates fixing the connecting arm to the sliding seat 108. The mounting ring 115 and the locking bolt 116 facilitate quick assembly and disassembly of the sample cylinder 109.

[0038] Additionally, one end of the fixed arm 117 is connected to the bottom of the mounting plate 104, and the sliding arm 118 is slidably disposed inside the other end of the fixed arm 117. The push ring 124 is installed at the end of the sliding arm 118 away from the mounting plate 104. Both the fixed arm 117 and the sliding arm 118 are hollow structures. The second servo motor 119 is installed at the inner bottom of the fixed arm 117. The output end of the second servo motor 119 is provided with the second threaded rod 120. The second ball screw nut pair 121 is provided on the second threaded rod 120. The second ball screw nut pair 121 is connected to the inner bottom wall of the sliding arm 118. When the second servo motor 119 is started, the second threaded rod 120 is driven to rotate. Since the second ball screw nut pair 121 is connected to the sliding seat 108, the sliding arm 118 is driven to slide inside the fixed arm 117, thereby completing the lifting and lowering of the push ring 124.

[0039] Furthermore, a limiting block 127 is provided at the end of the second threaded rod 120 away from the second servo motor 119. The limiting block 127 prevents the second ball screw nut pair 121 from detaching from the second threaded rod 120. At the same time, the limiting block 127 is located inside the fixed arm 117, thereby preventing the sliding arm 118 from falling out of the fixed arm 117.

[0040] When using the quality inspection device for highway construction according to this embodiment, when the sampling cylinder 106 is moved to the sampling area by the handcart 101, the height adjustment mechanism 103 is activated, causing the mounting plate 104 to descend continuously. Simultaneously with the descent of the mounting plate 104, the drive motor 105 is activated, causing the sampling cylinder 106 to rotate, thereby completing the concrete sampling. The push handle 123 and the push plate 122 facilitate the extraction of concrete samples from the sampling cylinder 106. After the concrete sampling in the sampling cylinder 106 is completed, the height adjustment mechanism 103 drives the mounting plate 104 to reset, allowing the sampling cylinder 106 to return to its original position. The sample cylinder 109 is moved to the top of the mounting bracket 102 and the sliding seat 108 is slid on the mounting guide rail 107 by the driving component. This moves the sample cylinder 109 below the sampling cylinder 106. After the sample cylinder 109 moves below the sampling cylinder 106, the pushing component is activated. The pushing ring 124 applies force to the pushing handle 123, causing the push plate 122 to slide downward inside the sampling cylinder 106. This pushes the concrete sample in the sampling cylinder 106 into the sample cylinder 109, completing the collection of the concrete sample. With the above structure, the operation is more convenient when collecting the concrete sample in the sampling cylinder 106.

[0041] Second embodiment:

[0042] Based on the first embodiment, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the quality inspection device for highway construction according to the second embodiment. Figure 7 for Figure 6 A magnified view of the local structure at point C.

[0043] The present invention provides a quality inspection device for highway construction, which also includes a protective plate 201.

[0044] In this specific embodiment, a through groove 202 is provided on the sliding seat 108, and a protective plate 201 is provided inside the through groove 202. The two ends of the protective plate 201 are respectively connected to the two ends of the mounting guide rail 107. By providing the protective plate 201, the end face of the mounting guide rail 107 is protected to avoid the external environment from affecting the operation of the drive component.

[0045] The protective plate 201 has connecting blocks 203 on both sides. One end of the connecting block 203 is connected to the side of the protective plate 201, and the other end of the connecting block 203 is connected to the side of the mounting guide rail 107. The installation of the protective plate 201 is completed by setting the connecting blocks 203.

[0046] When using the quality inspection device for highway construction according to this embodiment, the installation of the protective plate 201 is completed by setting the connecting block 203. The protective plate 201 protects the end face of the mounting guide rail 107, preventing the external environment from affecting the operation of the drive component.

[0048] S1: The sample cylinder 109 is installed on the end of the connecting arm away from the sliding seat 108, and the sliding seat 108 is driven to slide on the mounting guide rail 107 by the driving component, so that the sample cylinder 109 is away from the bottom of the sampling cylinder 106.

[0049] S2: Start the height adjustment mechanism 103 to drive the mounting plate 104 to descend continuously. While the mounting plate 104 is descending, start the drive motor 105 to drive the sampling cylinder 106 to rotate, thereby completing the concrete sampling.

[0050] S3: After the concrete sampling in the sampling tube 106 is completed, the height adjustment mechanism 103 drives the mounting plate 104 to reset, and the driving component drives the sliding seat 108 to slide on the mounting guide rail 107, so that the sample tube 109 moves to below the sampling tube 106.

[0051] S4: When the sample cylinder 109 moves to the bottom of the sampling cylinder 106, the pushing assembly is activated. The pushing ring 124 applies force to the pushing handle 123, causing the push plate 122 to slide downward inside the sampling cylinder 106, thereby pushing the concrete sample in the sampling cylinder 106 into the sample cylinder 109, thus completing the collection of the concrete sample.

[0052] In this embodiment, when the sampling cylinder 106 is moved to the sampling area by the handcart 101, the height adjustment mechanism 103 is activated, causing the mounting plate 104 to descend continuously. Simultaneously, the drive motor 105 is activated to rotate the sampling cylinder 106, thereby completing the concrete sampling. The push handle 123 and the push plate 122 facilitate the extraction of concrete samples from the sampling cylinder 106. After the concrete sampling in the sampling cylinder 106 is completed, the height adjustment mechanism 103 drives the mounting plate 104 to reset, causing the sampling cylinder 106 to return to the mounting frame. At the top of the interior of 102, the sliding seat 108 is driven by the driving component to slide on the mounting guide rail 107, so that the sample cylinder 109 moves to below the sampling cylinder 106. After the sample cylinder 109 moves to below the sampling cylinder 106, the pushing component is activated, and the pushing ring 124 applies force to the pushing handle 123, causing the push plate 122 to slide downward inside the sampling cylinder 106, thereby pushing the concrete sample in the sampling cylinder 106 into the sample cylinder 109, completing the collection of the concrete sample. With the above structure, the operation is more convenient when collecting the concrete sample in the sampling cylinder 106.
