Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an engineering quality testing device for building supervision. Background Technology

[0002] With the vigorous development of the modern construction industry, the quality and safety of construction projects have received increasing attention. Construction supervision plays a crucial role in ensuring project quality. As a key tool in supervision, engineering quality testing devices are widely used in the strength, hardness, and other performance tests of building structures such as concrete and walls. Their function is to provide scientific basis for supervisors to judge whether the project quality meets the design standards and specifications through accurate test data, thereby promptly identifying potential quality hazards and ensuring the safety and durability of construction projects.

[0003] However, existing engineering quality testing devices have certain shortcomings in practical use. On the one hand, during the testing process, it is difficult to keep the impact head perpendicular to the testing surface at all times, which can easily lead to inaccurate test data due to angular deviation, affecting the judgment of engineering quality. Moreover, after the test is completed, the reset of related components is not convenient, which reduces the testing efficiency. On the other hand, when the impact head is worn or damaged and needs to be replaced, the disassembly and installation process of the existing device is relatively cumbersome, often requiring the use of additional tools, which is time-consuming and labor-intensive, bringing many inconveniences to the testing work. Therefore, an engineering quality testing device for building supervision is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an engineering quality testing device for building supervision, which aims to improve the problems of inaccurate test data caused by angular deviation and the need to replace the impact head in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction quality inspection device for building supervision includes a housing. Two slide rails are fixedly connected to the outer side of the housing. A slide rod is fixedly connected inside the two slide rails. A spring is sleeved on the outer side of the slide rod. A slider is slidably connected to the outer side of the slide rod. A ring is fixedly connected to the outer side of the slider. Multiple connecting rods are fixedly connected to the outer side of the ring. A pad is fixedly connected to the end of each connecting rod away from the ring. Connecting rods are slidably connected to the outer side of each connecting rod. A connector is fixedly connected to the end of each connecting rod away from the connecting rod. A detection component is disposed inside the housing.

[0007] As a further description of the above technical solution:

[0008] The detection assembly includes a striking hammer, a central guide rod slidably connected inside the striking hammer, one end of the central guide rod passing through the striking hammer and fixedly connected to a baffle, a hook provided inside the baffle, a spring fixedly connected between the hook and the baffle, a pad fixedly connected to the inner wall of the outer shell, multiple striking tension springs provided inside the outer shell, a striking rod fixedly connected to the end of the central guide rod away from the striking hammer, a groove provided inside the striking rod, a connector slidably connected inside the striking rod, a convex ring fixedly connected to the outside of the connector, and a striking head fixedly connected to the side of the connector away from the striking rod;

[0009] As a further description of the above technical solution:

[0010] The slider slides inside the slide rail, and a rubber pad is fixedly connected to the side of the pad away from the connecting rod.

[0011] As a further description of the above technical solution:

[0012] One end of the second spring is fixedly connected to the outside of the slider, and the other end of the second spring abuts against the inner wall of the slide rail;

[0013] As a further description of the above technical solution:

[0014] The outer shell is slidably connected to the middle of the ring, and a scale is fixedly connected to the outer side of the outer shell;

[0015] As a further description of the above technical solution:

[0016] Both the impact hammer and the baffle slide inside the outer casing, and the other end of the impact spring is fixedly connected to the inner wall of the outer casing.

[0020] The convex ring is engaged inside the groove, one end of the spring is fixedly connected to one side of the impact hammer, and the other end of the spring is fixedly connected to the inner wall of the outer shell.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, during testing, the pad and the impact head are on the same plane via the rubber pad. When the rebound hammer is pushed, the second connecting rod slides outside the first connecting rod to adjust the impact head so that it is always perpendicular to the testing surface. At the same time, the ring slides inside the slide rail via the slider and squeezes the spring along the slide rod. When the impact head moves away from the testing surface, the spring pushes the slider, causing the ring to reset via the first connecting rod, thus preparing for the next test and improving the accuracy of the test data.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 5 This utility model provides an embodiment of an engineering quality testing device for building supervision, comprising a housing 1, two slide rails 2 fixedly connected to the outer side of the housing 1, slide rods 10 fixedly connected inside the two slide rails 2, springs 11 sleeved on the outer side of the slide rods 10, a slider 12 slidably connected to the outer side of the slide rods 10, a ring 7 fixedly connected to the outer side of the slider 12, multiple connecting rods 4 fixedly connected to the outer side of the ring 7, a pad 15 fixedly connected to the end of the connecting rods 4 away from the ring 7, connecting rods 5 slidably connected to the outer side of each connecting rod 4, and a connecting piece 8 fixedly connected to the end of the connecting rods 5 away from the connecting rods 4. A testing component is disposed inside the housing 1. The slider 12 slides inside the slide rails 2, and a rubber pad is fixedly connected to the side of the pad 15 away from the connecting rods 4. One end of the spring 11 is fixedly connected to the outer side of the slider 12, and the other end of the spring 11 abuts against the inner wall of the slide rail 2. The housing 1 is slidably connected to the middle of the ring 7, and a scale 22 is fixedly connected to the outer side of the housing 1.

[0035] The outer casing 1 provides operating space for internal parts; the slide rail 2 provides a sliding track to ensure smooth sliding; the slide rod 10 allows the slider 12 to slide smoothly inside the slide rail 2; the second spring 11 provides buffering and reset when the slider 12 slides; the slider 12 drives the ring 7 to slide smoothly inside the slide rail 2; the ring 7 provides initial restraint to the outer casing 1; the first connecting rod 4 provides support for the sliding of the second connecting rod 5; the pad 15 works with the rubber pad to increase the contact area with the detection surface and improve stability; the rubber pad better fits the detection surface while avoiding damage; the second connecting rod 5 can be extended and retracted within a certain range; the connector 8 integrates multiple second connecting rods 5 to make them slide synchronously. When performing concrete quality testing, the rubber pad contacts the detection surface, relying on the rubber... The friction of the pad and the support of the pad plate 15 provide initial stability. During testing, the pad plate 15 is on the same plane as the impact head 9 via the rubber pad. When the outer shell 1 is pushed, the connecting rod 1 4 is connected to the connecting piece 8 via the connecting rod 2 5. The connecting rod 2 5 slides outside the connecting rod 1 4 to adjust, ensuring that the impact head 9 is always perpendicular to the testing surface. At the same time, the connecting rod 1 4 causes the ring 7 to slide inside the slide rail 2 via the slider 12 and press the spring 2 11 along the slide rod 10. When the impact head 9 moves away from the testing surface, the spring 2 11 pushes the slider 12, causing it to drive the ring 7, which in turn causes the connecting rod 1 4 to reset the pad plate 15 and the rubber pad, preparing for the next test. This ensures that the outer shell 1 maintains a stable posture during the test, assists the outer shell 1 in being perpendicular to the testing surface, and improves the accuracy of the test data.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The detection assembly includes a striking hammer 19, with a central guide rod 21 slidably connected inside the striking hammer 19. One end of the central guide rod 21 passes through the striking hammer 19 and is fixedly connected to a baffle 18. A hook 3 is provided inside the baffle 18, and a spring 6 is fixedly connected between the hook 3 and the baffle 18. A pad 23 is fixedly connected to the inner wall of the outer casing 1, and multiple striking springs 20 are provided inside the outer casing 1. A striking rod 13 is fixedly connected to the end of the central guide rod 21 away from the striking hammer 19. A groove 17 is provided inside the striking rod 13, and a connector 16 is slidably connected inside the striking rod 13. A protruding ring 14 is fixedly connected to the outside of the connector 16, and a striking head 9 is fixedly connected to the side of the connector 16 away from the striking rod 13. The striking hammer 19 and the baffle 18 both slide inside the outer casing 1, and the other end of the striking spring 20 is fixedly connected to the inner wall of the outer casing 1. The striking rod 13 slides inside the connector 8, and the pad 23 is located directly above the hook 3. The convex ring 14 is engaged inside the groove 17, one end of the spring 20 is fixedly connected to one side of the impact hammer 19, and the other end of the spring 20 is fixedly connected to the inner wall of the outer shell 1.

[0037] The striking hammer 19 is used to strike the striking rod 13. The central guide rod 21 is used to allow the striking hammer 19 to slide inside the housing 1. The baffle 18 is used to provide operating space for the hook 3 and the spring 6. The spring 6 is used to cause the hook 3 to rebound. The hook 3 is used to hook the striking hammer 19. The pad 23 is used to squeeze the hook 3 to release the striking hammer 19. The striking spring 20 is used to pull the striking hammer 19 back to strike the striking rod 13. The striking rod 13 is used to cause the striking head 9 to act on the housing 1 of the rebound device. The groove 17 has a ring structure and the inner wall is smoothed to facilitate... The connector 16, in conjunction with the convex ring 14, enables quick engagement and disengagement. It is used to insert into the spring rod 13, allowing for smooth insertion and removal. The convex ring 14 is used to engage with the annular structure inside the groove 17 during insertion, connecting the spring head 9 to the spring rod 13. The spring head 9 is used to contact the measuring surface, and the scale 22 is used to view the measurement values. When the spring head 9 is worn or damaged and needs to be replaced, pulling the spring head 9 will compress the convex ring 14, causing it to disengage from the groove 17, thus separating the connector 16 from the spring rod 13 and allowing the spring head 9 to be replaced.

[0038] Working principle: During testing, the pad 15 is on the same plane as the impact head 9. When the outer shell 1 is pushed, the central guide rod 21 drives the impact hammer 19 to slide inward, and the impact spring 20 is stretched. When the hook 3 hits the pad block 23, the hook 3 releases the impact hammer 19, and the impact hammer 19 strikes the impact rod 13 to measure the concrete. The value is reflected on the scale 22. At the same time, the connecting rod 25 slides outside the connecting rod 14 to adjust the impact head 9 so that it is always perpendicular to the test surface. Meanwhile, the ring 7 slides inside the slide rail 2 through the slider 12 and compresses the spring 21 along the slide rod 10. When the impact head 9 moves away from the test surface... During surface inspection, the spring 20 causes the impact hammer 19 to rebound, and the second spring 11 pushes the slider 12, causing its ring 7 to reset via the connecting rod 4, thus preparing for the next inspection and improving the accuracy of the inspection data. When the impact head 9 is worn or damaged and needs to be replaced, the impact head 9 is pulled, and the convex ring 14 is squeezed and disengaged from the groove 17. This allows the connector 16 to be separated from the impact rod 13, the damaged impact head 9 to be pulled out, and the new impact head 9 to be inserted into the impact rod 13. The convex ring 14 is squeezed into the interior of the impact rod 13 and fits into the groove 17, thereby realizing the replacement of the impact head 9.
