Description

Technical Field

[0001] The utility model relates to the technical field of compactors, in particular to an anti-deviating compactor. Background Art

[0002] Geotechnical testing for water conservancy projects is a crucial step in evaluating soil and its engineering properties. It primarily studies the physical, chemical, and mechanical properties of soil. These tests, including soil particle analysis, compaction testing, shear testing, and permeability testing, provide essential data for design and construction. A compactor is a device used in geotechnical testing, primarily used to determine soil density and bearing capacity. Its operating principle is to repeatedly strike a soil sample with a weighted compactor hammer, which is dropped freely from a specified height. This causes friction and alignment of soil particles, achieving optimal compaction.

[0003] However, the existing compactors have the following shortcomings. When some compactors use hydraulically driven hammers to hammer the soil sample downward, the hammer head will vibrate slightly and the soil sample will be unevenly distributed. These conditions may cause the hammer head to deviate when it descends, which may easily lead to uneven force on the sample. Therefore, the existing compactors need to be improved.

[0027] During specific implementation, when some compactors use hydraulics to drive the hammer head to hammer the soil sample downward, the hammer head will vibrate slightly and the soil sample will be unevenly distributed. These situations may cause the hammer head to deviate when it descends, which may easily lead to uneven force on the sample. The hydraulic component 2 can push the lifting frame 14 downward, and the lifting frame 14 then drives the compacting hammer 10 to hammer the soil sample downward. At the same time, the lifting frame 14 slides downward in the guide groove 602 and the outside of the slide bar 603, and squeezes the support spring 604 downward, which can provide elastic support for the lifting frame 14 to prevent the lifting frame 14 from descending unstably. Through the setting of the guide groove 602 and the slide bar 603, the lifting frame 14 can be guided to prevent the compacting hammer 10 from deviating, thereby improving the working quality of the compactor.

[0028] See also Figure 2 、 Figure 3 and Figure 5-Figure 7 A screw rod 8 is installed in the built-in groove of the body 1 through a bearing, and one end of the screw rod 8 is connected to the motor 7 through a coupling.

The mounting mechanism 9 includes a handle 901, a limiting groove 902, a bidirectional screw rod 903 and a limiting block 904.

[0029] During specific implementation, the hammer head of the compactor will wear out after long-term use and needs to be replaced in time. However, the hammer head is not easy to disassemble, which will affect subsequent test work. The motor 7 can be used to drive the screw 8 to rotate, and the screw 8 and the moving block 601 are threadedly engaged, so that the moving block 601 drives the guide cover 5 to move downward on the screw 8, so that the lifting frame 14 is disengaged from the guide cover 5, and then the handle 901 is rotated to make the handle 901 drive the two-way screw rod 903 to rotate, and then the two-way screw rod 903 is threadedly engaged with the limit block 904, so that the limit block 904 moves to both sides on the two-way screw rod 903, and the limit block 904 is disengaged from the limit groove 902, and then the compacting hammer 10 is rotated to make the compacting hammer 10 drive the second threaded part 13 to be threadedly engaged with the first threaded part 12, so that one end of the compacting hammer 10 can be quickly disengaged from the docking groove 11, which is convenient for removing the compacting hammer 10 from the lifting frame 14 for replacement, thereby improving the convenience of the compacting hammer.

[0030] Working principle: When using the anti-drift compactor, first place the soil sample into the sample tube 3, then place the sample tube 3 on the support platform 4, then start the hydraulic assembly 2 to push the lifting frame 14 downward, and guide the lifting frame 14 and the compacting hammer 10 through the guide mechanism 6 to prevent the compacting hammer 10 from deviating during the hammering process. When the compacting hammer 10 needs to be disassembled and replaced, the compacting hammer 10 is disassembled and replaced from the lifting frame 14 through the installation mechanism 9, the No. 1 threaded part 12 and the No. 2 threaded part 13, which improves the convenience and working quality of the compactor.
