Description

Technical Field

[0001] The invention relates to the technical field of concrete quality detection, and in particular to a concrete quality detection device for green building construction. Background Art

[0002] As the concept of green building is deeply rooted in people's hearts, the quality requirements for construction materials are increasing day by day. As one of the most commonly used building materials, the quality of concrete is directly related to the structural safety and service life of the building. Concrete quality detection mainly includes compressive strength, flexural strength, frost resistance, impermeability and other aspects of the detection. Common detection methods include rebound method, ultrasonic detection method, core drilling method, pull-out method, etc., and the rebound value and sound velocity obtained by the rebound method and ultrasonic method test have no direct relationship with the strength of concrete, but are only indirect erosion of the reaction strength. It is easy to produce errors in the test, resulting in low detection accuracy. Drilling concrete core samples directly for compressive strength test is intuitive and reliable, but it has certain damage to the construction structure, and the cost is high, and a large number of tests cannot be carried out. Compared with the rebound method, ultrasonic method and core drilling method, the pull-out method is used for concrete quality detection. It is not only simple to operate and has high detection accuracy, but the pull-out method is also a detection method between non-destructive and core drilling methods, and the damage to the construction structure is small; The pull-out method is divided into the pre-embedded pull-out method and the post-installed pull-out method. The pre-embedded pull-out method embeds anchors during the construction process so that they can be directly pulled out during testing. However, the pre-embedded pull-out method is not very flexible and the testing position cannot be adjusted after the concrete solidifies. The post-installed pull-out method can perform a pull-out test on the hardened concrete at any time to detect the quality of the concrete. When testing by the post-installed pull-out method, it is necessary to drill holes, grind grooves, install anchors and finally pull them out. When the existing manual grooving operation is performed, a handheld groove grinder is required to grind the grooves, and it is difficult to grind multiple holes to the same size, resulting in inaccurate test data due to different sizes of grooves when performing pull-out testing. In addition, it is very time-consuming and labor-intensive to manually grind grooves at multiple points, resulting in low efficiency in concrete quality testing. Summary of the invention

[0020] Working principle: When the present invention is in use, the device is placed at the drilling site, the lifting motor 303 is controlled to be started, and the lifting gear 304 is driven to rotate by the lifting motor 303, driving the left lifting gear plate 305 to descend, so that the first connecting seat 306 drives the fixed cylinder 501 to descend, and the groove grinding rod 601 is driven to descend and inserted into the drill hole by the fixed cylinder 501, and then the groove grinding motor 503 is controlled to be started, and the fourth bevel gear 611 is driven to rotate by the groove grinding motor 503, and when the fourth bevel gear 611 rotates, the rotating shaft 607 is driven to rotate by the third bevel gear 610. At this time, since the synchronous rod 609 is inserted into the slide groove 608, when the rotating shaft 607 rotates, the rotating sleeve 604 is driven to rotate by the synchronous rod 609, so that the second bevel gear 605 rotates with the rotating sleeve 604, and when the second bevel gear 605 rotates, the groove grinding rod 601 is driven to rotate by the first bevel gear 603, so that the groove grinding rod 601 rotates; At the same time, after the groove grinding motor 503 is started, it drives the revolving gear 504 to rotate, so that the revolving gear 504 revolves around the fixed gear 505 while rotating, and drives the revolving cylinder 502 to rotate in the fixed cylinder 501, so that the slide box 602 rotates in the fixed cylinder 501 and follows the fixed cylinder 501 at the same time. At this time, the groove grinding rod 601 also rotates with the revolving cylinder 502, so that the rotating groove grinding rod 601 revolves with the fixed gear 505, so that the groove grinding rod 601 can contact the whole circle of the drill hole for groove grinding; When the rotating cylinder 502 rotates, the central shaft 717 and the extension rod are driven to rotate simultaneously, and the slot expansion gear ring 720 is fixedly connected to the fixed cylinder 501. Therefore, after the rotating cylinder 502 rotates one circle, the slot expansion gear 719 is driven to rotate, so that the central shaft 717 rotates with the slot expansion gear 719, and the extension rod is driven to rotate through the transmission chain 718, so that the threaded rod 703 rotates with the extension rod. When the threaded rod 703 rotates, the screw sleeve 708 rotates with the threaded rod 703 and has a tendency to move away from the central shaft 717. At this time, the elastic force of the return spring 716 makes the lifting plate 713 have a tendency to move toward the threaded rod 703. When the rotating cylinder 502 revolves, the sliding sleeve 706 has a centrifugal force in the direction of the rod groove 701 away from one end of the grinding groove rod 601. Therefore, the sliding sleeve 706 drives the screw sleeve 708 to move in this direction, so that the movable plate 711 moves with the sliding sleeve 706. At this time, the lifting plate 713 moves toward the screw sleeve 708, and the screw sleeve 708 rotates with the threaded rod 703. When the slot 709 contacts the lifting plate 713, the screw sleeve 708 rotates with the threaded rod 703. After the lowering plate 713 is inserted into the card slot 709, the screw sleeve 708 is limited. When the threaded rod 703 continues to rotate, the limited screw sleeve 708 drives the sliding sleeve 706 to continue to move to the end away from the rod groove 701 and away from the center of the rotating cylinder 502. The sliding sleeve 706 and the sliding seat 707 drive the sliding box 602 to move in the rotating cylinder 502, so that the grinding groove rod 601 moves with the sliding box 602 in the rod groove 701. At this time, the distance between the grinding groove rod 601 and the rotating axis of the rotating cylinder 502 gradually increases, so as to gradually The groove radius of the groove grinding rod 601 is gradually enlarged. The groove grinding rod 601 is driven to rotate while driving the groove grinding rod 601 to revolve around the center of the revolving cylinder 502. The rotation radius is gradually increased during the rotation and revolving to enlarge the groove grinding radius. The groove size is based on the length of the rod groove 701. After the length of the rod groove 701 is adaptively adjusted according to the actual groove grinding needs, the groove grinding device can obtain the same size of the extraction groove, which not only saves the time of manual groove grinding for the staff, but also reduces the error in the concrete quality inspection. When the sliding sleeve 706 drives the sliding box 602 to move to the end of the threaded rod 703, the movable plate 711 first contacts the inner wall of the support frame 702. When the sliding sleeve 706 contacts the inner wall of the support frame 702, the movable plate 711 is squeezed and moves into the connecting frame 710, and the limiting column 714 is driven to rise through the limiting groove 712, and the lifting plate 713 is driven to rise through the limiting column 714, so that the lifting plate 713 is pulled out of the slot 709. At this time, the screw sleeve 708 contacts the limit. When the threaded rod 703 continues to When the rotation continues, the screw sleeve 708 rotates simultaneously with the threaded rod 703 while the sliding sleeve 706 does not move, so that the groove radius of the groove grinding rod 601 can be expanded to the maximum radius. After the groove grinding rod 601 continues to rotate, the fixed cylinder 501 can also continue to rotate. When the groove grinding is completed, the groove grinding motor 503 is controlled to rotate in the reverse direction, and the sliding sleeve 706 is driven to move toward the support frame 702 close to the center of the rotating cylinder 502, so that the groove grinding radius of the groove grinding rod 601 gradually decreases to zero, that is, returns to the center of the rotating cylinder 502; After the groove grinding is completed, the device is lifted and removed by pulling up the hand frame 2, and the anchor is installed manually. This process does not involve standardized operations. It is only necessary to install the anchor in the grinding groove, so it does not affect the detection data. After the anchor is completed, the lifting motor 303 is controlled to start the reverse rotation, so that the groove grinding rod 601 rises and the puller 4 descends. After the device is rotated, the puller 4 is sleeved on the outside of the anchor. After the anchor is fixedly connected to the puller 4, the pull-out motor on the puller 4 is started to drive the puller 4 to pull the anchor upward, so as to perform concrete quality inspection through the post-installation pull-out method. Through the battery 8 in the support tube 301, the device can work outdoors for a long time, which improves portability, saves labor time, and greatly improves the efficiency of concrete quality inspection and the accuracy of inspection data.
