Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering exploration equipment technology, and more specifically, to a vertical auxiliary device for a cone dynamic penetration test rod. Background Technology

[0002] The cone penetration test employs an automatic drop hammer method. The hammer is raised to a position 0.76m above the top of the probe rod and then dropped freely to impact the top of the rod. The number of hammer blows per 10cm drop is counted to qualitatively evaluate the soil homogeneity and mechanical properties, and to analyze the location of soil cavities, sliding surfaces, and the interface between soft and hard soil layers. According to the "Code for Geotechnical Investigation" GB 50332-2001 (2009 edition), the maximum deviation of the probe rod's verticality during the hammer impact must not exceed 2%.

[0003] Currently, the cone penetration test equipment is used in conjunction with the XY-1 vertical shaft rotary hydraulic drilling rig. During the cone penetration test, workers use a hammer holder to vertically stabilize the probe rod, ensuring that the maximum deviation of the probe rod's verticality does not exceed 2%. During the test, the cone probe is inserted into soil layers containing rock, gravel layers, or uneven strata, making the probe rod prone to shifting or tipping. The hammer holder may not be able to maintain the overall vertical stability of the probe rod, leading to significant errors in the test data. Manually correcting the verticality of the probe rod is difficult and prone to causing safety accidents. Furthermore, the test points are widely distributed and far apart, requiring substantial manpower to transport the hammer holder. Summary of the Invention

[0004] The purpose of this utility model is to provide a vertical auxiliary device for a cone dynamic penetration test probe rod, which solves the problem that the probe rod is prone to deviation or tilting during the cone dynamic penetration test, requiring manual correction which is difficult and the hammer seat is difficult to transport. The device ensures that the verticality deviation of the probe rod is within the set standard range, reduces test data error, effectively improves work efficiency, and reduces the intensity of manual labor.

[0005] This utility model discloses a vertical auxiliary device for a cone dynamic penetrometer probe, comprising: an annular stabilizer, a buffer connecting pad, a support rod, a fixing adjuster, and a base fixer. The annular stabilizer is connected to the support rod through the buffer connecting pad, and the support rod is connected to the base fixer through the fixing adjuster.

[0006] Further specifying, the annular stabilizer includes an outer stabilizing post, a strong spring, a fixing hook, and an inner hollow guide post.

[0007] Further specifying, the buffer connecting pad includes a circular rubber block and a screw.

[0008] Further specifying, the fixing adjuster includes a fixing block, a rotating block, a fixing nut, and a fixing screw.

[0009] Further specifying, the bearing platform fixer includes a fixed bearing platform and a long bolt, the fixed bearing platform is provided with internal threads, and the long bolt is connected to the internal threads of the fixed bearing platform.

[0010] Furthermore, the outer stabilizing column (11) and the inner hollow guide column (15) have three threaded holes (12) spaced at equal angles along the circumference, and all the threaded holes (12) are located at the same horizontal height; each threaded hole is equipped with a fixing hook, the fixing hook including a steel hook and a screw, the screw being threadedly engaged with the threaded hole; the inner hollow guide column is coaxially sleeved inside the outer stabilizing column, and the outer stabilizing column and the inner hollow guide column are connected by a strong spring, the two ends of the strong spring being fixed to the corresponding fixing hooks of the outer stabilizing column and the inner hollow guide column, respectively.

[0011] With its circumferentially oriented threaded hole layout at equal angles and heights, the three-point high-strength spring can evenly buffer probe offset, quickly correct verticality, and avoid manual intervention.

[0012] The beneficial effects of this utility model are as follows: Through the layout of threaded holes at equal angles and heights throughout the circumference, the three-point high-strength spring can uniformly buffer probe rod offset, achieving uniform buffering and rapid correction of multi-angle probe rod offset, further reducing the frequency of manual intervention and improving the device's adaptive adjustment capability; by setting a buffer connecting pad to reduce the impact on the stability of the XY-1 vertical shaft rotary hydraulic drilling rig when the probe rod collides with the inner guide hollow column; by setting a fixed adjuster, the device and the support platform fixer can be raised or lowered without affecting the moving speed and efficiency of the XY-1 vertical shaft rotary hydraulic drilling rig. This utility model has a simple structure, is easy to operate and disassemble, ensures testing standards, effectively reduces test result errors, lowers the risk of operator injury, reduces labor intensity and operating costs, and improves work efficiency.

[0029] The ring stabilizer 1 is assembled, as follows: Figure 2 .
