Description

Technical Field

[0001] This utility model relates to the field of standard penetrators, specifically a water conservancy supervision earthwork detection device. Background Technology

[0002] After backfilling, the bearing capacity of the backfill needs to be tested. In existing technology, a standard penetration test is generally performed using a penetrator.

[0003] In existing technology, the penetrator needs to be raised 76 centimeters and then allowed to fall freely to strike the penetrator. The number of blows (i.e., penetration blows N) is recorded when the penetrator moves down 10 centimeters. Based on the standard penetration blows N, the bearing capacity of the foundation soil can be determined directly by referring to the bearing capacity table of the relevant specifications. For example, for cohesive soil, the corresponding bearing capacity characteristic value can be found based on the N value. Alternatively, empirical formulas can be used for calculation, such as the sand bearing capacity formula suggested by Terzaghi and Pick.

[0004] In existing technologies, workers need to manually move the hammer upwards repeatedly and then let it fall freely, which is cumbersome and inconvenient. Utility Model Content

[0019] 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.

[0020] Please see Figures 1-4 In this embodiment of the utility model, a water conservancy supervision earthwork detection device includes a base 1, a guide sleeve 2 integrally formed at the center of the base 1, a penetrator 3 slidably connected to the inner cavity of the guide sleeve 2, a fixing frame 7 installed on the top of the base 1, a forward and reverse motor 8 installed at the bottom of the top plate of the fixing frame 7, a lifting mechanism installed at the output end of the forward and reverse motor 8, a hammer pad 5 integrally formed on the outer circumference of the penetrator 3, a vertical hole 16 opened at the top of the hammer pad 5 inside the penetrator 3, the top of the vertical hole 16 is open, a hooking mechanism is installed at the output end of the lifting mechanism, vertical grooves 4 are opened on both sides of the outer wall of the penetrator 3, a through hammer 6 slidably connected to the inner wall of the vertical hole 16 and extending to the outside of the penetrator 3, a connecting hole 24 slidably connected to the penetrator 3 inside the through hammer 6, and a downwardly recessed central hole 17 is opened at the top of the center of the through hammer 6. The inner wall of the hammer 6 is provided with a groove 18. The bottom end of the movable plate 12 is fixedly connected to a connecting rod 13. The connecting rod 13 passes through the top of the penetrator 3 to the inner connecting rod 13 of the penetrator 3. An inwardly protruding inner protrusion 14 is integrally formed on the upper part of the inner wall of the vertical hole 16. An extrusion slope 15 is integrally formed on the lower inner side of the inner protrusion 14.

[0021] In this embodiment: When determining the bearing capacity of the backfill soil, a hole approximately 15 cm deep is first drilled in the foundation. Then, the base 1 is placed on the backfill soil surface. At this point, the center of the guide sleeve 2 at the center of the base 1 is aligned with the center of the hole. The penetrator 3 then falls into the hole under gravity. Next, the lifting mechanism is activated, causing the hooking mechanism to move downwards. The downward-moving hooking mechanism moves down along the inner wall of the vertical hole 16 until it is fully inserted into the central hole 17. At this point, the hooking mechanism is aligned with the annular hook groove 18. The rear lifting mechanism operates in reverse, driving the hooking mechanism to move upward. The upward-moving hooking mechanism pulls the through hammer 6 upward through the hook groove 18 until it pulls the through hammer 6 upward by 76 centimeters. At this time, the hooking mechanism is completely retracted under the pressure of the compression slope 15 and no longer hooks the through hammer 6. At this time, the through hammer 6 falls freely under gravity and hits the top of the hammer pad 5. The hammer pad 5 is forced to move the penetrator 3 downward. The staff records the number of hammer blows when the penetrator 3 penetrates 10 centimeters downward, thus achieving the effect of testing the earth's bearing capacity.

[0022] Please refer to this carefully. Figure 1 and Figure 2 The lifting mechanism includes a forward and reverse motor 8 fixedly installed at the bottom of the top plate of the fixed frame 7. The output shaft of the forward and reverse motor 8 extends through to the top of the fixed frame 7. Upward protruding guide rods 10 are welded on both sides of the top plate of the fixed frame 7. Fixed plates 11 are fixedly installed on the top of the two guide rods 10. The output shaft of the forward and reverse motor 8 is fixedly connected to a screw 9. The top of the screw 9 is rotatably connected to the bottom end of the fixed plate 11. A movable plate 12 is threadedly connected to the outer wall of the guide rod 10. The movable plate 12 is slidably connected to the guide rod 10.

[0023] In this embodiment: by starting the forward and reverse motor 8, the forward and reverse motor 8 drives the screw 9 to rotate. At this time, the movable plate 12 is limited by the guide rod 10. The rotating screw 9 drives the movable plate 12 to move in the up and down direction. The movable plate 12 then drives the connecting rod 13 to slide up and down on the inner wall of the vertical hole 16.

[0024] Please refer to this carefully. Figure 3 and Figure 4 The hooking mechanism includes two slide grooves 19 formed inside the connecting rod 13. A spring 20 is fixedly installed at one end of the inner wall of the slide groove 19. A synchronization plate 21 that is slidably connected to the inner wall of the slide groove 19 is fixedly installed at one end of the spring 20. An outwardly protruding pressure block 22 is integrally formed on the upper outer side of the synchronization plate 21. An outwardly protruding hooking block 23 is integrally formed on the lower outer side of the synchronization plate 21. A first pressure inclined surface is integrally formed above the pressure block 22. A second pressure inclined surface is integrally formed below the hooking block 23.

[0025] In this embodiment: as the connecting rod 13 moves downward along the inner wall of the vertical hole 16, when the second pressure inclined surface of the hook block 23 contacts and squeezes the edge of the central hole 17, the hook block 23 pushes the synchronous plate 21 to slide in the slide groove 19. At this time, the spring 20 is compressed until the hook block 23 is completely inserted into the slide groove 19 and until the hook block 23 is aligned with the hook groove 18. At this time, the spring 20 is reset and pushes the synchronous plate 21 to move outward. The synchronous plate 21 drives the hook block 23 to be inserted into the hook groove 18. Then the lifting mechanism moves upward, and the lifting mechanism can drive the through hammer 6 to move upward through the hook mechanism.

[0026] During the process of the hooking mechanism moving upward to the highest position, the first pressure-bearing inclined surface of the pressure block 22 gradually approaches and contacts the extrusion inclined surface 15. Since the first pressure-bearing inclined surface matches the extrusion inclined surface 15, the pressure-bearing first pressure-bearing inclined surface drives the pressure block 22 to move towards the inside of the slide groove 19. At this time, the spring 20 is compressed again until the pressure block 22 is completely retracted into the slide groove 19. During this process, the pressure block 22 synchronously drives the hooking block 23 to retract synchronously. At this time, the penetrating hammer 6 moves upward to a height of 76 centimeters. The penetrating hammer 6, which has lost its hook, falls downward freely and strikes the hammer pad 5 and the penetrator 3 to achieve the standard penetration test.

[0027] Please refer to this carefully. Figure 2 and Figure 3 The inner diameter of the vertical hole 16 is larger than the outer diameter of the connecting rod 13.

[0028] In this embodiment, this design allows the connecting block 23 and the pressure block 22 to have space to pop outward, thus avoiding interference.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
