[0002] During the construction of water conservancy projects, in order to ensure quality and safety, it is usually necessary to detect the strength of dams, including the strength detection of the concrete structure of dams. The traditional method is to cut a small piece and then use a pressure testing machine to squeeze and test its strength;

[0003] However, in the actual detection process, when using a pressure testing machine to test the strength of a dam, when the test sample stone is stressed beyond its bearing limit, it will break and fly, which is easy to cause harm to the staff. And when the testing device tests the stone, due to the high hardness of the stone itself, it is easy to damage the pressure detection head, thus affecting the accuracy of the detection. However, it is very inconvenient to replace the pressure detection head of the existing device. Therefore, there is an urgent need to design a dam strength detector for water conservancy project detection that can prevent the stone from breaking and flying and can replace the pressure detection head conveniently and quickly.

The same flipping rod 16 is rotatably installed on one side of the two auxiliary metal blocks 15 close to each other. Two flipping gears 18 are fixedly sleeved on the flipping rod 16. A protection plate 17 is fixedly sleeved on the flipping rod 16.

[0022] In this embodiment, an L-shaped metal rod 7 is rotatably installed at the bottom of the pressure support seat 4. One end of the L-shaped metal rod 7 is connected to the control metal block 6. Two limit rods 8 are fixedly installed on one side of the positioning metal block 5. Sliders 9 are fixedly installed on both sides of the first limit block 10. Both sliders 9 are slidably sleeved on the corresponding limit rods 8.

[0023] In this embodiment, the same second limit block 12 is fixedly installed at one end of the two limit rods 8. The bottom of the second limit block 12 is fixedly installed on one inner wall of the replacement chamber. Limit springs 11 are sleeved on the two limit rods 8. One end of each of the two limit springs 11 is fixedly installed on one side of the same first limit block 10. The other ends of the two limit springs 11 are fixedly connected to one side of the same second limit block 12.

[0024] In this embodiment, a protection chamber is opened inside the detector main body 1. A protection base 21 is fixedly installed on one inner wall of the protection chamber. A plurality of moving grooves are opened on the top of the protection base 21. Moving columns 22 are slidably installed on one inner wall of the plurality of moving grooves. Transmission metal strips 23 are fixedly installed on the tops of the plurality of moving columns 22.

[0025] In this embodiment, a plurality of moving sliders 20 are slidably installed on the top of the protection base 21. Two transmission holes are opened on one side of each of the plurality of moving sliders 20. The plurality of transmission metal strips 23 are slidably installed in the corresponding transmission holes. Flipping straight racks 19 are fixedly installed on the tops of the plurality of moving sliders 20. The plurality of flipping straight racks 19 are all meshed with the corresponding flipping gears 18.

[0026] In this embodiment, a transmission groove is formed at the top of the protection base 21. A transmission slider 24 is slidably mounted on one inner wall of the transmission groove. A transmission ball screw 25 is rotatably mounted on one inner wall of the transmission groove. The transmission slider 24 is threadedly sleeved on the transmission ball screw 25. The top of the transmission slider 24 is connected to the corresponding moving slider 20.

[0027] In this embodiment, a transmission servo motor 26 is fixedly mounted on one inner wall of the protection chamber. The output shaft of the transmission servo motor 26 is connected to the transmission ball screw 25. A control panel 27 is fixedly mounted on one side of the detector main body 1. The transmission servo motor 26 and the hydraulic press 2 are both electrically connected to the same control panel 27.

[0028] Working principle: During detection, first place the sample stone on the detection base 14, and then start the transmission servo motor 26 through the control panel 27. The start of the transmission servo motor 26 drives the transmission ball screw 25 to rotate. The rotation of the transmission ball screw 25 drives the transmission slider 24 to move. The movement of the transmission slider 24 drives the corresponding moving slider 20 to move. The movement of the moving slider 20 drives the corresponding two transmission metal bars 23 to move. The other ends of the two transmission metal bars 23 are both slidably mounted in the corresponding moving sliders 20. Therefore, the movement of the two transmission metal bars 23 drives the corresponding moving sliders 20 to move. Two transmission metal bars 23 are slidably mounted in each of the two driven moving sliders 20. Therefore, the movement of the two moving sliders 20 drives the other transmission metal bar 23 slidably mounted therein to move. The movement of the two transmission metal bars 23 drives the same moving slider 20 to move. At this time, multiple moving sliders 20 all move inward. The inward movement of multiple moving sliders 20 drives the flipping straight racks 19 fixedly mounted thereon to move. The movement of multiple flipping straight racks 19 drives the corresponding two flipping gears 18 to rotate. The rotation of multiple flipping gears 18 drives the corresponding flipping rods 16 to rotate. The rotation of multiple flipping rods 16 drives the corresponding protection plates 17 to flip to the designated position. At this time, multiple protection plates 17 surround the same detection base 14 to prevent the stones that are crushed under pressure during detection from splashing and causing injury to the staff. When the pressure detection head 13 is worn, stop the machine. Then the staff rotates the L-shaped metal rod 7. The rotation of the L-shaped metal rod 7 drives the control metal block 6 to rotate. The rotation of the control metal block 6 releases the extrusion on the first limit block 10. When the extrusion on the first limit block 10 is released, at this time, the two limit springs 11 extend to generate a thrust force to push the same first limit block 10 to move. The movement of the first limit block 10 releases the limit on the pressure detection head 13. At this time, the staff holds the pressure detection head 13 and disassembles it, and then replaces it. Repeat the above steps to limit the replaced pressure detection head 13 to complete the replacement.

[0029] The technological progress achieved by the present utility model compared with the prior art is as follows: The mechanism provided can block the broken and splashing stones, ensuring the safety of the staff to the greatest extent. At the same time, it can also fix the stones to be tested to prevent them from moving, increasing the safety and stability of the device. Moreover, the pressure detection head 13 can be replaced through the provided mechanism, which is convenient and fast, and also helps to improve the detection accuracy, increasing the practicality of the device.
