Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete detection, and particularly relates to a positioning device for concrete detection. Background Art
[0002] Reinforced concrete structures are the most commonly used building structures in current housing construction. The quality of the concrete therein is directly related to the lifespan of reinforced concrete buildings, and the compressive strength of the concrete is one of the main indicators directly reflecting the quality level of the concrete. Therefore, it is necessary to detect and process the concrete.
[0003] However, when the existing concrete is detected, the concrete test blocks are often directly placed on the working table of the concrete compression testing machine. Since there is no structure for individually positioning the concrete test blocks, it is easy to place the test blocks unevenly, resulting in uneven stress on the detected concrete test blocks and inaccurate detected data.
[0004] In view of this, the utility model designs a positioning device for concrete detection to solve the above problems. Summary of the Utility Model
[0005] Purpose of the Utility Model: The purpose of the utility model is to provide a positioning device for concrete detection in view of the deficiencies in the current technology.
[0006] Technical Solution: To achieve the above purpose, the utility model provides a positioning device for concrete detection, including a bottom plate. Symmetrically fixed to the bottom plate are support rods. Grooves are respectively formed inside the two support rods. Slidingly connected inside the two grooves are lifting rods. The upper ends of the two lifting rods are fixedly connected to a top plate. Fixed to the lower surface of the top plate is a first cylinder. The lower end of the first cylinder is fixedly connected to a connecting plate. Fixed to the lower surface of the connecting plate is a rebound hammer. Installed on the bottom plate between the two support rods is a positioning assembly for fixing the position of the concrete.
[0007] Further, the positioning assembly includes two through holes formed in the bottom plate. Slidingly connected to the upper surface of the bottom plate are two limit blocks. Fixed below the two limit blocks are two limit rods respectively inserted into the two through holes. Fixed between the two limit rods and located below the bottom plate is a slider. A lead screw penetrates through the two sliders, and the lead screw is threadedly connected to the two sliders.
[0008] Further, a second cylinder is fixedly connected inside the groove, and the upper end of the second cylinder contacts the lower end of the lifting rod.
[0009] Further, a bubble level is fixedly connected to the upper surface of the top plate.
[0010] Beneficial effects: By installing a positioning component on the bottom plate, the positioning component can ensure that the concrete is fixed and at the same time ensure that the concrete is in the center position of the bottom plate, improving the accuracy of the detection result.
[0011] By sliding the lifting rod inside the support rod, the lifting rod can be adjusted so that the top plate is always in a horizontal position, and then ensure that the rebound instrument is always in a horizontal position, further ensuring the accuracy of the detection result.

Detailed implementation manners
[0016] The present utility model will be further clarified below in conjunction with the drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present utility model and not to limit the scope of the present utility model. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component.
[0017] Example 1, according to Figures 1 - 3 Make further explanatory notes.
[0018] The present utility model provides a positioning device for concrete detection, including a bottom plate 1, symmetrically and fixedly connected with support rods 2 on the bottom plate 1, grooves 3 are respectively opened inside the two support rods 2, lifting rods 4 are respectively slidably connected inside the two grooves 3, the upper ends of the two lifting rods 4 are fixedly connected with a top plate 5, a first cylinder 6 is fixedly connected to the lower surface of the top plate 5, the lower end of the first cylinder 6 is fixedly connected to a connecting plate 8, a rebound instrument 9 is fixedly connected to the lower surface of the connecting plate 8, a positioning component located between the two support rods 2 is installed on the bottom plate 1, and the positioning component is used to fix the position of the concrete.
[0019] The positioning component includes two through holes 10 formed in the bottom plate 1. Two limit blocks 11 are slidably connected to the upper surface of the bottom plate 1. Two limit rods 12 are fixedly connected below the two limit blocks 11 and are respectively inserted into the two through holes 10. A slider 13 is fixedly connected between the two limit rods 12 and located below the bottom plate 1. A lead screw 14 passes through the two sliders 13, and the lead screw 14 is threadedly connected to the two sliders 13.
[0020] A second cylinder 7 is fixedly connected inside the groove 3, and the upper end of the second cylinder 7 contacts the lower end of the lifting rod 4.
[0021] A bubble level 15 is fixedly connected to the upper surface of the top plate 5.
[0022] When it is necessary to detect the concrete, the operator first places the concrete sample on the upper surface of the bottom plate 1. Subsequently, by rotating the lead screw 14 that passes through the two sliders 13 and is threadedly connected to the sliders 13, the rotation directions at both ends of the lead screw 14 are opposite. Therefore, when the lead screw 14 is rotated forward, the two sliders 13 will approach each other. Furthermore, the slider 13 fixedly connected between the two limit rods 12 will drive the limit blocks 11 slidably connected to the upper surface of the bottom plate 1 to approach each other. Since the adjacent ends of the two limit blocks 11 are V-shaped and the angle is 90 degrees, when the two limit blocks 11 approach each other, the limit blocks 11 will be completely attached to the corners of the rectangular concrete, thereby improving the stability of the concrete. And because the two sliders 13 are centrosymmetric, the moving distances of the two sliders 13 are the same. Furthermore, the concrete can be pushed by the limit blocks 11 to move to the center position of the bottom plate 1, thereby ensuring the accuracy of the detection.
[0023] Since slight wear may occur during the use of the machine, causing the entire device to tilt and thus affecting the detection results, a second cylinder 7 is fixedly connected to the groove 3 formed inside the support rod 2. The contraction and extension of the second cylinder 7 can drive the lifting rod 4 slidably connected inside the groove 3 to move up and down. Furthermore, the top plate 5 fixedly connected to the upper end of the lifting rod 4 can be adjusted. When the bubble level fixed to the upper surface of the top plate 5 is horizontal, the second cylinder 7 stops working to ensure that the rebound hammer 9 fixed to the lower surface of the connecting plate 8 is horizontal.
[0024] Subsequently, the operator starts the first cylinder 6 fixed to the lower surface of the top plate 5. The first cylinder 6 extends to drive the connecting plate 8 fixed to the lower end of the first cylinder 6 to move downward. The downward movement of the connecting plate 8 drives the rebound hammer 9 fixed to the lower surface of the connecting plate 8 to move downward. During the downward movement of the rebound hammer 9, it contacts the concrete, and the rebound hammer 9 deforms. Subsequently, the relevant data obtained by the rebound hammer 9 are obtained, and thus the detection work of the concrete is completed.
[0025] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only for the specific embodiments of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
