[0012] As a further technical solution of this utility model, the fixed sleeve is internally threaded, and the threaded rod is externally threaded. The threads of the internal and external threads are standard trapezoidal threads, and their thread helix angle is less than the equivalent friction angle.

[0013] As a further technical solution of this utility model, the fixing sleeve is sleeved on the outside of the threaded rod, the fixing sleeve and the threaded rod are threadedly connected, and the limiting slider slides up and down inside the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the building foundation strength measuring device not only facilitates the cleaning of the probe rod and the disassembly and assembly of the mounting plate, but also improves the stability of the device; The system includes a pre-reserved slot, mounting bracket, cleaning sponge, limit block, fixing rod, and groove. When the hydraulic cylinder drives the probe rod to rise, the cleaning sponge on the inner wall of the limit block can clean the outer wall of the probe rod, preventing dirt from adhering to the surface of the probe rod for a long time and making it inconvenient to clean. When the cleaning sponge needs to be disassembled and replaced, the limit block is rotated to open from the left and right sides of the top of the pre-reserved slot. When the limit block is opened, the mounting bracket will lose its fixation, making it convenient to replace the mounting bracket and cleaning sponge. The scale on the frame and the front end of the probe rod allows for easy observation of the depth of the probe rod's descent. The system includes an installation block, installation slot, limit rod, limit slot, spring, and pull plate. When the probe needs to be installed inside the frame, pulling the pull plate moves the limit rod outward. After the rod moves, the installation slot at the top of the installation plate fits over the bottom of the installation block. Releasing the pull plate allows the spring to use its elasticity to embed the limit rod inside the limit slot, thus fixing the installation block and installation slot. This completes the installation of the probe. To remove the probe, simply pull the pull plate again to release the mounting slot. The device is equipped with a fixed sleeve, a protective sleeve, a threaded rod, a throttle, a connecting rod, a limiting groove, and a limiting slider. After pushing the base to the appropriate position, the throttle is turned, which drives the threaded rod to rotate. Because the fixed sleeve and the threaded rod cooperate with each other, and the limiting slider on one side of the fixed sleeve slides inside the limiting groove, the rotation of the threaded rod can cause the fixed sleeve to drive the connecting rod to descend, embedding the connecting rod inside the soil and limiting and fixing the device. Limiting and fixing the device can prevent the device from accidentally sliding and affecting the measurement. Using the fixed sleeve and the threaded rod to drive the connecting rod to descend can prevent soil from being embedded outside the threaded rod and affecting the next use.

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.

[0018] Please see Figure 1-4 The present invention provides an embodiment of a building foundation strength measuring device, comprising a base 1, a frame 7 fixedly connected to the top of the base 1, a hydraulic cylinder 10 installed at the top inside the frame 7, an installation block 9 installed at the bottom of the hydraulic cylinder 10, an installation plate 11 provided at the bottom of the installation block 9, a probe rod 15 installed at the bottom of the installation plate 11, and a reserved groove 13 provided in the middle position inside the base 1, the reserved groove 13 being provided with a cleaning structure to facilitate cleaning of the probe rod 15. The cleaning structure includes a mounting frame 16 and a cleaning sponge 17. The mounting frame 16 is installed inside the reserved groove 13. The cleaning sponge 17 is fixedly connected to the inner side wall of the mounting frame 16. The left and right sides of the top of the mounting frame 16 are fixedly connected to the fixing rods 19. The left and right sides of the top of the base 1 are movably hinged to the limiting blocks 18. The limiting block 18 has a groove 20 on the side near the middle. The left and right sides of the front end of the probe rod 15 and the frame 7 are respectively machined with scales. The left and right sides of the mounting plate 11 are fixedly connected to the finger rods 8. The bottom end of the probe rod 15 is set inside the reserved groove 13. The limiting block 18 is locked to the top of the fixed rod 19 through the groove 20. The limiting block 18 is set on the left and right sides of the top of the mounting bracket 16. The finger rod 8 is set on the left and right sides inside the frame 7. The four corners of the bottom of the base 1 are equipped with movable casters 2. Specifically, such as Figure 1 and Figure 2 As shown, when the hydraulic cylinder 10 drives the probe rod 15 to rise, the cleaning sponge 17 on the inner side wall of the limiting block 18 can clean the outer side wall of the probe rod 15 to prevent dirt from adhering to the surface of the probe rod 15 for a long time and making it inconvenient to clean. When the cleaning sponge 17 needs to be disassembled and replaced, the limiting block 18 is rotated to open from the left and right sides of the top of the reserved groove 13. When the limiting block 18 is opened, the mounting frame 16 will lose its fixation, which makes it convenient to replace the mounting frame 16 and the cleaning sponge 17. The scale on the frame 7 and the front end of the probe rod 15 can be used to easily observe the depth of the probe rod 15's descent.

[0019] The top of the mounting plate 11 is fixedly connected to the mounting groove 12. The mounting block 9 and the left and right sides of the mounting groove 12 are respectively provided with limit slots 24. The left and right sides of the mounting groove 12 are provided with pull plates 26. The pull plate 26 is fixedly connected to the middle side of the pull plate 26 with a limit rod 23. A spring 25 is fixedly connected between the mounting groove 12 and the pull plate 26. The bottom end of the mounting block 9 is fixed inside the mounting groove 12 through the limit rod 23 and the limit slot 24. The bottom end of the mounting block 9 is embedded inside the mounting groove 12. The limit rod 23 is embedded inside the limit slot 24. The spring 25 is set on the outside side of the limit rod 23. Specifically, such as Figure 1 and Figure 4As shown, when the probe rod 15 needs to be installed inside the frame 7, pull the pull plate 26. The pull plate 26 drives the limiting rod 23 to move outward. After moving, the mounting groove 12 at the top of the mounting plate 11 is fitted onto the bottom of the mounting block 9. Release the pull plate 26. The spring 25 uses its own elasticity to make the limiting rod 23 embedded in the limiting slot 24 to limit and fix the mounting block 9 and the mounting groove 12, thus completing the installation of the probe rod 15. When the probe rod 15 needs to be disassembled, pull the pull plate 26 again to make the mounting groove 12 lose its fixation.

[0020] Protective sleeves 4 are fixedly connected to the left and right sides of the base 1. A threaded rod 5 is movably connected to the top of the inside of the protective sleeve 4. A handle 6 is fixedly connected to the top of the threaded rod 5. A fixed sleeve 3 is provided at the bottom of the outside of the threaded rod 5. A connecting rod 14 is fixedly connected to the bottom of the fixed sleeve 3. A limiting groove 21 is opened on the side of the inside of the protective sleeve 4 near the outside. A limiting slider 22 is fixedly connected to the top of the side of the fixed sleeve 3 near the outside. The inside of the fixed sleeve 3 is machined with internal threads, and the outside of the threaded rod 5 is machined with external threads. The threads of the internal and external threads are standard trapezoidal threads, and their thread helix angle is less than the equivalent friction angle. The fixed sleeve 3 is sleeved on the outside of the threaded rod 5. The fixed sleeve 3 and the threaded rod 5 are threadedly connected. The limiting slider 22 slides up and down inside the limiting groove 21. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, after pushing the base 1 to the appropriate position, turn the handle 6. The handle 6 drives the threaded rod 5 to rotate. Since the fixed sleeve 3 and the threaded rod 5 cooperate with each other, and the limiting slider 22 on one side of the fixed sleeve 3 slides inside the limiting groove 21, the rotation of the threaded rod 5 can cause the fixed sleeve 3 to drive the connecting rod 14 to descend, so that the connecting rod 14 is embedded in the soil to limit and fix the device. Limiting and fixing the device can prevent the device from accidentally sliding and affecting the measurement. Using the fixed sleeve 3 and the threaded rod 5 to drive the connecting rod 14 to descend can prevent the soil from being embedded outside the threaded rod 5 and affecting the next use.

[0021] Working principle: When using this utility model, after pushing the base 1 to the appropriate position, rotate the handle 6. The handle 6 drives the threaded rod 5 to rotate. Since the fixed sleeve 3 and the threaded rod 5 cooperate with each other, and the limiting slider 22 on one side of the fixed sleeve 3 slides inside the limiting groove 21, the rotation of the threaded rod 5 can cause the fixed sleeve 3 to drive the connecting rod 14 to descend, so that the connecting rod 14 is embedded in the soil to limit and fix the device. Limiting and fixing the device can prevent the device from accidentally sliding and affecting the measurement. Using the fixed sleeve 3 and the threaded rod 5 to drive the connecting rod 14 to descend can prevent the soil from being embedded outside the threaded rod 5 and affecting the next use. When it is necessary to install the probe 15 inside the frame 7, pull the pull plate 26. The pull plate 26 drives the limiting rod 23 to move outward. After moving, the mounting groove 12 at the top of the mounting plate 11 is put on the bottom of the mounting block 9. Release the pull plate 26, and the spring 25 will release through its own... The elasticity of the limit rod 23 allows it to be embedded inside the limit slot 24, limiting and fixing the mounting block 9 and the mounting groove 12, thus completing the installation of the probe rod 15. When the probe rod 15 needs to be disassembled, simply pull the pull plate 26 again to make the mounting groove 12 lose its fixation. The hydraulic cylinder 10 drives the probe rod 15 to descend, measuring the strength of the foundation. The scale on the frame 7 and the front end of the probe rod 15 allows for easy observation of the descent depth of the probe rod 15. When the hydraulic cylinder 10 drives the probe rod 15 to rise, the cleaning sponge 17 on the inner side wall of the limit block 18 can clean the outer side wall of the probe rod 15, preventing dirt from adhering to the surface of the probe rod 15 for a long time and making cleaning inconvenient. When the cleaning sponge 17 needs to be disassembled and replaced, rotate the limit block 18 to open it from the left and right sides of the top of the reserved groove 13. When the limit block 18 is turned open, the mounting frame 16 will lose its fixation, thus facilitating the replacement of the mounting frame 16 and the cleaning sponge 17.
