Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering investigation technology, and in particular to a soil sample extraction auxiliary device for geotechnical engineering investigation. Background Technology

[0002] Geotechnical engineering investigation requires soil sampling, which is mainly carried out by exploration drilling rigs. The collected soil samples are kept in the soil sampling tube at the end of the drill bit. In the existing technology, the surface of the soil sampling tube has a vertical groove. Workers remove the soil sample by inserting a steel rod into the groove and applying pressure.

[0003] In the existing soil sampling process, the pressure applied by the steel rod can easily cut the soil sample, affecting its integrity. Furthermore, the sampling is affected by the position of the slot, making it difficult to extract the entire soil sample. In addition, during the soil sample extraction process, the bottom of the soil lacks necessary support and is prone to tipping over and breaking, resulting in soil sample shrinkage. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing an auxiliary soil sample pressing device for geotechnical engineering investigation.

[0005] This utility model is achieved through the following technical solution:

[0006] A soil sample extraction auxiliary device for geotechnical engineering investigation includes a base, a support rod, a supporting ring, a limiting ring, a guide seat, a guide rod, a pressure plate, a pressure rod, a handle, a lifting mechanism, a limiting strip, and a connecting seat. The support rod is fixedly mounted on the top of the base, the supporting ring is fixedly mounted on the top of the support rod, the limiting ring is fixedly mounted on the upper surface of the supporting ring, the guide seat is fixed to the outer side of the supporting ring, the guide rod is engaged within the guide seat, the pressure plate is fixedly mounted on the top of the guide rod, the pressure rod is fixedly mounted on the bottom of the pressure plate, the handle is fixed to both sides of the pressure plate, the lifting mechanism is engaged within the bottom of the guide rod, and the limiting strip is fixed to the edge of the upper surface of the connecting seat. The lifting mechanism includes a lifting seat, a guide strip, a spring, a pressure strip, a locking strip, and a socket. The guide strip is fixedly mounted inside the lifting seat, the spring is sleeved on the outer side of the guide strip, the pressure strip is movably connected to the guide strip, the locking strip is fixedly mounted on one side of the pressure strip, and the socket is fixedly mounted on the outer side of the lifting seat.

[0007] In a preferred embodiment of the present invention, the support seat has an installation groove inside that cooperates with the retaining strip and the pressure strip, and both ends of the pressure strip and one end of the retaining strip pass through and extend to the outside of one side of the support seat.

[0008] By applying pressure to the end of the pressure bar, the locking bar can be retracted, thereby locking the lifting mechanism at the bottom of the guide rod.

[0009] In a preferred embodiment of the present invention, the bottom of the guide rod is provided with a locking hole that cooperates with the locking strip, and the end of the locking strip is locked in the locking hole at the bottom of the guide rod;

[0010] The clip has a flat structure, which facilitates connection with the guide rod and ensures that the support seat is horizontal after installation.

[0011] In a preferred embodiment of this utility model, a pressure plate is fixedly provided at the bottom of the pressure rod, and the pressure rod, the support ring, the base and the limiting ring are arranged coaxially;

[0012] The coaxial setup allows for better extrusion of soil samples from the sampling tube.

[0013] In a preferred embodiment of this utility model, the limiting strip is fitted inside the socket.

[0014] The beneficial effects of this utility model are:

[0015] This soil sample extraction auxiliary device for geotechnical engineering investigation can extract soil samples completely. During the extraction process, the bottom of the soil sample is effectively supported and the sides of the soil sample are limited, so that the extracted soil sample is more complete and avoids the soil sample falling, tipping over, or breaking, thus making the soil sample more valuable for reference.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] like Figure 1-3 The illustrated soil sample extraction auxiliary device for geotechnical engineering investigation includes a base 1, a support rod 2, a supporting ring 3, a limiting ring 4, a guide seat 5, a guide rod 6, a pressure plate 7, a pressure rod 8, a handle 9, a lifting mechanism 10, a limiting strip 11, and a connecting seat 12. The support rod 2 is fixedly mounted on the top of the base 1, the supporting ring 3 is fixedly mounted on the top of the support rod 2, the limiting ring 4 is fixedly mounted on the upper surface of the supporting ring 3, the guide seat 5 is fixed to the outside of the supporting ring 3, the guide rod 6 is engaged inside the guide seat 5, the pressure plate 7 is fixedly mounted on the top of the guide rod 6, and the pressure rod 8 is fixedly mounted on the bottom of the pressure plate 7. The handle 9 is fixed to both sides of the pressure plate 7. The lifting mechanism 10 is locked inside the bottom of the guide rod 6. The limiting strip 11 is fixed to the upper surface edge of the connecting seat 12. The lifting mechanism 10 includes a lifting seat 101, a guide strip 102, a spring 103, a pressure strip 104, a locking strip 105, and a socket 106. The guide strip 102 is fixed inside the lifting seat 101. The spring 103 is sleeved on the outside of the guide strip 102. The pressure strip 104 is movably connected to the guide strip 102. The locking strip 105 is fixed on one side of the pressure strip 104. The socket 106 is fixed on the outside of the lifting seat 101.

[0022] Specifically, the support seat 101 has an installation groove inside that mates with the retaining strip 105 and the pressure strip 104. Both ends of the pressure strip 104 and one end of the retaining strip 105 pass through and extend to the outside of one side of the support seat 101. The bottom of the guide rod 6 has a retaining hole that mates with the retaining strip 105. The end of the retaining strip 105 is engaged in the retaining hole at the bottom of the guide rod 6. A pressure plate is fixedly installed at the bottom of the pressure rod 8. The pressure rod 8, the support ring 3, the base 1 and the limiting retaining ring 4 are coaxially arranged. The limiting strip 11 is engaged in the socket 106.

[0023] In this embodiment, after the exploration drilling rig rotates and presses the soil sampling pipe into the soil, the soil sample collection is completed. Then, the soil sampling pipe containing the soil sample is locked inside the limiting ring 4. The bottom of the soil sampling pipe will contact the upper surface of the supporting ring 3. At this time, the guide rod 6 is locked inside the guide seat 5 and pressed down until it moves to the bottom of the supporting ring 3. Then, the lifting mechanism 10 is installed. The two ends of the pressure strip 104 locked to the outside of the lifting seat 101 are squeezed inward, so that the locking strip 105 retracts inward. The lifting seat 101 is locked inside the guide rod 6, and under the action of the spring 103, the locking strip 105 pops out and its end is locked into the bottom locking hole of the guide rod 6, thus completing the installation of the lifting mechanism 10.

[0024] Furthermore, the connecting seat 12 is placed inside the base 1, and the guide rod 6 is controlled to move downward until the end of the limiting strip 11 is engaged in the socket 106. At this time, the pressure plate at the bottom of the pressure rod 8 applies pressure to the top of the soil inside the soil sampling tube. The control handle 9 is pressed down so that the pressure plate 7 applies pressure to the pressure rod 8, pressing out the soil inside the soil sampling tube. The bottom of the pressed-out soil will be effectively supported by the lifting seat 101, and its side will be limited by the limiting strip 11, thereby preventing the pressed-out soil sample from breaking, crumbling, or falling, and ensuring the integrity of the soil sample.
