Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a core thickness measuring instrument. Background Technology

[0002] In the field of modern construction and engineering, the testing of concrete and other building materials is becoming increasingly important to ensure construction quality and building safety. Traditional testing methods mostly rely on surface measurement or destructive sampling, which is not only time-consuming and labor-intensive, but may also damage the materials being tested. In recent years, although some new technologies such as ultrasonic testing and radar testing have been widely used, these technologies are often limited by problems such as the thickness of the material to be tested, high cost, or complex operation. Core thickness gauges are a more advanced non-destructive testing device that can accurately measure the thickness of materials without damaging them.

[0003] However, existing core thickness measuring instruments have defects in the installation of the cutting blade. They cannot make precise pre-adjustment of the cutting blade position, which affects the subsequent fixing of the cutting blade with bolts and nuts. This makes the installation process inconvenient and inaccurate, and increases the installation time and labor intensity of workers. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1: This utility model provides a core thickness measuring instrument, such as... Figures 1 to 4As shown, the system includes a frame body 1. A lifting frame 2 is movably connected to the outer surface of the top of the frame body 1. A handle 3 is rotatably connected inside the lifting frame 2. A gear is fixedly connected to one end of the handle 3. The gear is rotatably connected to the inside of the lifting frame 2. A rack is meshed with the outer surface of the gear. One end of the rack is fixedly connected to the outer surface of the frame body 1. A motor 4 is fixedly installed at one end of the lifting frame 2. A linkage rod 5 is fixedly connected to the output end of the motor 4. A drill barrel 6 is fixedly connected to the bottom end of the linkage rod 5. Multiple movable grooves 7 are opened inside the bottom end of the drill barrel 6. A positioning block 8 is movably connected to the outer surface of the movable grooves 7 inside the drill barrel 6. A bolt is threadedly connected inside the positioning block 8. A nut is threadedly connected to one end of the bolt on the outer surface of the drill barrel 6. A cutting blade 9 is fixedly connected to the bottom end of the positioning block 8. A spring telescopic rod 10 is fixedly connected to the top of the positioning block 8. A pressing block 11 is fixedly connected to one end of the spring telescopic rod 10. The pressing block 11 is movably connected to the inside of the positioning block 8 on the outer surface. A roller 12 is rotatably connected to one end of the pressing block 11.

[0021] like Figure 1 and Figure 4 As shown, a diversion chamber 13 is fixedly connected to the bottom of the motor 4 at the position outside the linkage rod 5. The outer surface of the linkage rod 5 is movably connected to the inside of the diversion chamber 13. A water inlet pipe 14 is fixedly connected to the top of the diversion chamber 13. Multiple nozzles 15 are fixedly connected to the bottom of the diversion chamber 13. A guide shroud 16 is fixedly connected to the outer surface of the nozzles 15. The external water pipe is connected to the water inlet pipe 14. The external water source enters the inside of the diversion chamber 13 along the water inlet pipe 14, and then sprays out from the inside of the multiple nozzles 15 and falls down. The sprayed water is blocked by the guide shroud 16 and slides down along the inner wall of the guide shroud 16, landing around the cutting blade 9 to cool down the cutting blade 9. The guide shroud 16 can prevent water from splashing everywhere, avoid wasting water, and ensure that the cutting blade 9 is fully and continuously covered by water, avoiding wear of the cutting blade 9 due to the lack of water in some areas, and ensuring the long-term stable use of the cutting blade 9.

[0022] like Figure 1 and Figure 2 As shown, positioning grooves 17 are provided on both sides of the top of the movable groove 7 inside the drill barrel 6. The outer surface of the extrusion block 11 is movably connected to the inside of the positioning groove 17. As the extrusion block 11 moves, when the extrusion block 11 reaches the corresponding position of the positioning groove 17, it is no longer squeezed by the movable groove 7. Under the elastic force of the spring telescopic rod 10, the extrusion block 11 is driven to move outward and engage into the inside of the positioning groove 17. At this time, the pre-precision adjustment of the position of the cutting blade 9 is completed.

[0023] like Figure 1 and Figure 3 As shown, the top and bottom of one end of the extrusion block 11 are both sloped to reduce the resistance when the extrusion block 11 contacts the outer surface of the movable groove 7, so that the extrusion block 11 can smoothly enter the interior of the movable groove 7.

[0024] like Figure 1 and Figure 3 As shown, the outer surface of the roller 12 is in contact with the outer surface of the movable groove 7. The roller 12 can reduce the friction when the positioning block 8 contacts the movable groove 7, thereby increasing the moving speed of the positioning block 8.

[0025] like Figure 1 and Figure 4 As shown, the interior of the flow guide shroud 16 is hollow. The cross-section of the flow guide shroud 16 is composed of a square and a trapezoid, with the square at the top and the trapezoid at the bottom. This guides the water flow into the interior of the flow guide shroud 16, causing the water to slide down the inner wall of the flow guide shroud 16 and fall around the cutting blade 9, thus cooling the cutting blade 9.

[0026] Working principle: In actual use, the positioning block 8 is first aligned with the movable groove 7. Then, the positioning block 8 is moved upwards. The movement of the positioning block 8 drives the cutting blade 9 and the extrusion block 11 to move synchronously. As the extrusion block 11 moves, its inclined surface contacts the outer surface of the movable groove 7 and applies force to it. The extrusion block 11 then applies force to the spring telescopic rod 10, causing it to contract. This causes the extrusion block 11 to move inwards. Then, the positioning block 8 continues to move upwards, causing the outer surface of the roller 12 to contact the outer surface of the movable groove 7 and move along the outer surface of the movable groove 7. As the extrusion block 11 moves, when it reaches the corresponding position in the positioning groove 17, it is no longer squeezed by the movable groove 7. Under the elastic force of the spring telescopic rod 10, the extrusion block 11 moves outward and engages with the positioning groove 17. At this point, the initial positioning of the cutting blade 9 is completed. Then, the nut is tightened, and the cutting blade 9 is fixed again by the bolt and nut. This simplifies the installation process of the cutting blade 9 and allows for precise pre-adjustment of the position of the cutting blade 9, ensuring that it will not affect the subsequent fixing of the cutting blade 9 with bolts and nuts, thus improving the convenience and accuracy of installation.

[0027] Then, the external water pipe is connected to the inlet pipe 14. The external water source enters the distribution chamber 13 along the inlet pipe 14, and then sprays out from the inside of multiple nozzles 15 and falls. The sprayed water is blocked by the guide shroud 16 and slides down along the inner wall of the guide shroud 16, landing around the cutting blade 9 to cool it down. The guide shroud 16 can prevent water from splashing everywhere, avoid wasting water, and ensure that there is a continuous water flow around the cutting blade 9, avoiding wear of the cutting blade 9 due to the lack of water in some areas, thus ensuring the long-term stable use of the cutting blade 9.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
