Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a cone dynamic penetration instrument with an anti-sway structure. Background Art

[0002] "Geological survey" is the investigation and research activity of geological exploration and detection through various means and methods to determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the bearing layer, and calculate the foundation parameters. It is an investigation and research work on the geological conditions such as rocks, strata, structures, minerals, hydrology, landforms, etc. in a certain area. Usually, geological survey is required in construction, water conservancy projects, etc., and a dynamic probe is required when conducting geological survey. The dynamic probe is a cone probe of a certain specification that is artificially driven into the soil using a certain amount of hammer energy. The bearing capacity of each soil layer is determined according to the number of penetration hammer blows, and a comprehensive evaluation of the foundation soil is made. When conducting foundation bearing capacity testing, one person is generally required to support the probe rod, and the other person grabs the handles on both sides of the hammer head and lifts it upward. After reaching a certain height, let go and let the hammer head fall freely to test the depth of the probe into the soil.

[0003] The existing patent (publication number: CN220150263U) discloses a cone dynamic prober assembly, which relates to the technical field of geological survey and foundation detection equipment. The assembly includes a hammer seat on the guide rod; a hammer head is provided on the movable sleeve outside the guide rod; a probe rod is screwed on the lower end of the guide rod; a probe is connected to the lower end of the probe rod; a guide base is detachably provided on the outer sleeve of the guide rod; three support assemblies are rotatably connected under the guide base. The utility model is used on a cone dynamic prober for foundation bearing capacity detection test, which can improve the operability of the test and the accuracy of the test data. The device is a protective limit device set on the probe rod, which is peeled off from the probe rod during the test, and the lower end can be easily inserted into the soil, and the entire prober can be kept stable during the hammering process. At the same time, the limit device can keep the probe rod vertical during the hammering process. This structure has a wide adjustment range and strong applicability. At the same time, the guide base is horizontally placed and fixed by setting the support assembly. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The prior art uses three ground cones to fix the probe on the ground, but the ground cones are completely inserted into the soil by manpower, with a limited insertion depth and are not stable enough. They are easily tilted and shaken by external factors during subsequent use; 2. In addition, when conducting geological surveys with existing probes, the ground is usually uneven, and the second threaded rod needs to be rotated to adjust the length of the three legs. However, because the legs are long and have a certain weight, frequent bending and adjustment consumes a lot of time and increases work intensity. Utility Model Content

[0023] In this embodiment, Figure 2 As shown, one end of the fixed rod 605 is fixedly connected to the outer surface of the vertical rod 4, and there are two fixed rods 605, which are symmetrically distributed about the center line of the vertical rod 4; this structure, together with the pulley 602 in the middle of the upper part, can bring the two pull ropes 603 together in the middle, thereby driving the probe 5 to rise vertically and preventing the probe 5 from tilting.

[0024] In this embodiment, Figure 1 , Figure 2 and Figure 5As shown, the adjustment component 7 includes three inner sleeves 701 hinged at the bottom of the top plate 1, and the inner middle parts of the three inner sleeves 701 are all threadedly connected with adjusting screws 702, the bottom end of the adjusting screw 702 is fixedly connected with a first bevel gear 703, one side of the first bevel gear 703 is meshed with a second bevel gear 704, and the middle part of the second bevel gear 704 is penetrated by a rocker 705, the middle part of the adjusting screw 702 is rotatably connected to the middle part of the fixing plate 706, and the fixing plate 706 is fixedly connected between the inner walls of the outer sleeve 707; the adjustment component 7 can drive the outer sleeve 707 to move along the inner sleeve 701 by rotating the rocker 705, which is easier than the traditional adjustment method and does not require the entire support leg to be twisted for adjustment.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the rocker 705 passes through both sides of the outer sleeve 707, a limit block is provided at one end of the rocker 705, and the other end of the rocker 705 is an "L"-shaped structure; the limit block can prevent the rocker 705 from falling off from the outer sleeve 707, and the "L"-shaped structure increases the power arm, making the adjustment more labor-saving.

[0026] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the fixing assembly 8 includes a motor 801 fixedly connected to the inside of the outer sleeve 707, the output end of the motor 801 is fixedly connected to a threaded rod 802, the threaded rod 802 is threadedly connected to the middle of the conical block 803, two sliders 804 are fixedly connected to both sides of the conical block 803, the two sliders 804 are slidably connected to the inside of the slide groove 805, four trapezoidal blocks 806 are fitted to the outer bottom of the conical block 803, and one side of the four trapezoidal blocks 806 is respectively fixedly connected to a spring 807 and a ground-inserting rod 808; the threaded rod 802 is driven by the motor 801 to rotate so that the conical block 803 moves along the central axis direction of the outer sleeve 707, thereby squeezing the four trapezoidal blocks 806, and finally squeezing the ground-inserting rod 808 out of the outer sleeve 707 and inserting it into the ground. Since the ground-inserting rod 808 is perpendicular to the outer sleeve 707, the probe can be reinforced to prevent shaking during geological surveys.

[0027] In this embodiment, Figure 4 As shown, one end of the ground-inserting rod 808 extends to the outside of the outer sleeve 707, and an elastic structure is formed between the outer sleeve 707 and the trapezoidal block 806 through a spring 807; this structure can automatically retract the ground-inserting rod 808 outside the outer sleeve 707 after the conical block 803 moves up, so as to prevent the ground-inserting rod 808 from hindering the ground-inserting cone 9 from being pulled out of the soil.

[0028] The use method and advantages of the utility model: When the cone dynamic penetration instrument with an anti-sway structure is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when it is necessary to survey the geology, the three ground cones 9 of the cone dynamic probe are separated so that they are distributed at equal angles, and then the ground cones 9 are inserted into the soil. At this time, the level meter 3 is observed. If one side is higher, the rocker 705 is rotated in the corresponding direction. When the rocker 705 rotates, it will drive the second bevel gear 704 to rotate, and the second bevel gear 704 drives the first bevel gear 703 to rotate. The first bevel gear 703 drives the adjusting screw 702 to move in the internal threaded hole at the bottom of the inner sleeve 701. Because the adjusting screw 702 and the outer sleeve 707 are connected by the fixing plate 706, the outer sleeve 707 can be extended and retracted on the outside of the inner sleeve 701 when the adjusting screw 702 moves, thereby adjusting the length of the support part and making the top plate 1 of the dynamic probe parallel to the ground. This adjustment method can adjust the length of the support part by rotating the rocker 705, which is easier and more convenient to adjust. Then the motor 801 is started to drive the threaded rod 8 02 rotates, the threaded rod 802 rotates, the tapered block 803 moves downward, and the trapezoidal block 806 is squeezed outward, and the trapezoidal block 806 pushes the ground rod 808 to extend out of the outer sleeve 707. Since the ground rod 808 and the outer sleeve 707 are perpendicular to each other, the probe can be reinforced to prevent shaking during geological surveys. Then, the vertical rod 4 and the probe 5 at the bottom thereof are pulled up by the pull rope 603 and the fixing rod 605. When the probe 5 is pulled to the required height, the self-centering card is used to The disk 2 clamps the vertical rod 4. At this time, the probe 5 and the vertical rod 4 are perpendicular to the ground. The self-centering chuck 2 is loosened to allow the probe 5 to fall freely into the ground. The bearing capacity of the foundation is tested by the depth of the probe. After the test is completed, the motor 801 is reversed to move the conical block 803 upward. At this time, the trapezoidal block 806 will rebound and reset under the action of the spring 807, thereby driving the external ground-inserting rod 808 to be retracted into the outer sleeve 707 to prevent the ground-inserting rod 808 from hindering the ground-inserting cone 9 from being pulled out of the soil.
