Description

Technical Field

[0001] The invention relates to the field of civil engineering, in particular to a rock and soil sampling device for geotechnical engineering investigation. Background Art

[0002] In geotechnical engineering investigations, engineers use a variety of sampling devices to obtain samples of underground rock and soil layers. These devices usually need to be able to work under different geological conditions and obtain undisturbed, representative rock and soil samples. In order to cope with various working environments and conditions, they usually choose to use handheld electric drills. The handheld electric drill is designed to be lightweight and easy for one engineer to carry and operate, which is especially important in survey points that are difficult to access or have narrow spaces. In many cases, this convenient tool can quickly and effectively complete shallow sampling of soil or softer rocks, greatly improving work efficiency.

[0003] Although the handheld electric drill has its unique features in operation, it is not without disadvantages. During the sampling process, engineers need to work continuously for a long time, and then the limitations of the handheld electric drill begin to emerge. Since the electric drill will produce a certain amount of vibration when in use, and engineers need to use arm strength to maintain stability and control, which makes long-term work particularly strenuous. As the working time increases, engineers may feel arm fatigue, which will directly affect the accuracy and quality of sampling. If the arm is weak, the positioning of the electric drill may become inaccurate, and the angle, depth and speed of sampling may deviate, which will affect the representativeness of the sample and the reliability of the experimental results. For this reason, we propose a geotechnical sampling device for geotechnical engineering investigation. Summary of the invention

[0030] See also Figure 1-7 A geotechnical sampling device for geotechnical engineering investigation comprises a geotechnical sampling vehicle 1, wherein the bottom of the geotechnical sampling vehicle 1 is provided with driving wheels 2 at four corners respectively, an empty slot 3 is provided at the end of the geotechnical sampling vehicle 1, a propulsion handle 4 is fixedly installed at the top of the geotechnical sampling vehicle 1 at the corresponding edge position, side protection plates 5 are fixedly provided on both sides of the top of the geotechnical sampling vehicle 1 corresponding to the empty slot 3, a sampling drill bit 6 is provided between the two groups of side protection plates 5, a cross-shaped transmission slot 23 is provided at the end of the sampling drill bit 6, a driving motor 16 is fixedly provided between the two groups of side protection plates 5 at the top of the geotechnical sampling vehicle 1, and a driving gear 17 is sleeved on the output end of the driving motor 16, and further comprises:

[0031] A storage assembly, which is installed on the side protection plate 5 and is used to store the sampling drill bit 6 to prevent the sampling drill bit 6 from being bumped;

[0032] The driving and separating assembly is installed between the two sets of side protection plates 5 and is used to drive or drive and separate the sampling drill bit 6 .

[0033] The two sets of side protection plates 5 have side shafts 7 rotatably connected to one side corresponding to each other, and a ring sleeve 8 is fixedly connected between the two sets of side shafts 7. The ring sleeve 8 is sleeved on the outer wall of the sampling drill bit 6. The top and bottom of the ring sleeve 8 are fixedly connected to L plates 9, and the ends of the two sets of L plates 9 are fixedly connected to clamping blocks 10. The sampling drill bit 6 is clamped in the ring sleeve 8 through the transmission groove 23 and the transmission frame 22 to rotate so as to sample the rock and soil. By arranging the sampling drill bit 6 between the two sets of side protection plates 5, the action of the operator holding the sampling drill bit 6 is reduced, and the labor intensity of the operator during operation is reduced. At the same time, by storing the sampling drill bit 6, the rock and soil sampling vehicle 1 is prevented from bumping against the sampling drill bit 6 during the forward movement, thereby improving the safety of the device and extending the service life of the sampling drill bit 6.

[0034] A disc 11 is sleeved on the outer wall of the sampling drill bit 6, and the disc 11 is rotatably connected between the two groups of clamping blocks 10. The disc 11 synchronously follows the sampling drill bit 6 to rotate between the two groups of clamping blocks 10, preventing the sampling drill bit 6 from shifting forward and backward during the rotation process, making the rotation of the sampling drill bit 6 more stable. By utilizing the transmission frame 22 to be clamped in the transmission groove 23, the sampling drill bit 6 can be effectively rotated during operation, thereby improving the efficiency of the sampling drill bit 6 during sampling.

[0035] The storage assembly includes an adjusting disk 12, a slide bar 13, a return spring 14 and a limit gasket 15, wherein the end of one group of side shafts 7 is extended to the outside of the side protection plate 5 and is sleeved with an adjusting disk 12, and the adjusting disk 12 is slidably connected with a slide bar 13 that runs through both sides of the adjusting disk 12, and one end of the slide bar 13 corresponding to the side protection plate 5 is sleeved with a return spring 14, and the outer wall of the slide bar 13 is sleeved with a limit gasket 15 corresponding to the side of the return spring 14, and the end of the slide bar 13 is slidably inserted into the outer side of the side protection plate 5. When the corresponding sampling drill bit 6 needs to be stored, the limit straight rod 26 is first pulled upward to make the limit straight rod 26 out of the limit The push plate 19 is then slid toward the initial position to disengage the driven gear 21 from the driving gear 17, thereby disengaging the transmission frame 22 from the transmission groove 23, and pulling the slide bar 13 toward the outside of the adjusting disk 12. The slide bar 13 drives the limit gasket 15 to slide during the sliding process on the adjusting disk 12, so that the reset spring 14 is compressed and shortened until the end of the slide bar 13 is out of the side of the side protective plate 5, and then the adjusting disk 12 is rotated ninety degrees. The side shaft 7 drives the sampling drill bit 6 to rotate ninety degrees through the rotation of the adjusting disk 12, and the end of the sampling drill bit 6 corresponding to the transmission groove 23 is rotated into the empty groove 3.

[0036] A groove is provided on the outer side of one group of side protection plates 5 corresponding to the side of the adjustment disk 12, and the end of the slide rod 13 is movably inserted in the groove. When the slide rod 13 is rotated to the groove position, the slide rod 13 is relaxed and the rebound force of the reset spring 14 is used to drive the limit gasket 15 to insert the end of the slide rod 13 into the groove, thereby preventing the sampling drill bit 6 of the geotechnical sampling vehicle 1 from shaking during driving.

[0037] The driving separation component includes an adjusting groove 18, a push plate 19, a transmission shaft 20, a driven gear 21 and a transmission frame 22. The two groups of side guard plates 5 are both provided with an adjusting groove 18. A push plate 19 is slidably connected between the two groups of adjusting grooves 18.

A cross-shaped transmission frame 22 is fixedly provided on the side of the driven gear 21 corresponding to the sampling drill bit 6. The transmission frame 22 is slidably engaged in the transmission groove 23. The transmission shaft 20 drives the driven gear 21 to mesh with the driving gear 17 through the sliding of the push plate 19. At this time, the transmission frame 22 is just engaged in the transmission groove 23 on the sampling drill bit 6. The driving motor 16 is started so that the output shaft on the driving motor 16 drives the driving gear 17 to start rotating. The driven gear 21 drives the transmission frame 22 to rotate by meshing with the driving gear 17.

[0038] The driving separation component also includes a limiting straight rod 26, a top plate 27 and a limiting circular hole 28, wherein a top plate 27 is fixedly provided on the inner side of one group of side protection plates 5 corresponding to the adjusting groove 18, and a limiting circular hole 28 is provided on the top of the top plate 27 corresponding to the side of the adjusting groove 18, and the top of the push plate 19 corresponds to the inner side of one group of side protection plates 5 and is slidably connected to the limiting straight rod 26, and the bottom end of the limiting straight rod 26 is slidably inserted in the limiting circular hole 28. When the limiting straight rod 26 on the push plate 19 slides to the top of the limiting circular hole 28, the limiting straight rod 26 is pushed downward so that the bottom end of the limiting straight rod 26 is inserted into the inside of the limiting circular hole 28 through the push plate 19.

[0039] The two ends of the push plate 19 extend out of the two groups of side protection plates 5 through the two groups of adjustment grooves 18 and are sleeved with semi-circular arc panels 24. The outer sides of the two groups of side protection plates 5 are provided with transverse grooves 25 at the upper and lower positions of the two groups of adjustment grooves 18. The two ends of the two groups of arc panels 24 are slidably engaged in the two groups of transverse grooves 25. When it is necessary to sample the rock and soil, the two groups of arc panels 24 are first pulled to make the two groups of arc panels 24 slide in the transverse grooves 25, and the push plate 19 is displaced in the adjustment groove 18 through the sliding of the two groups of arc panels 24.

[0040] Working principle: When sampling of rock and soil is required, first pull the two sets of arc panels 24 to make the two sets of arc panels 24 slide in the horizontal groove 25, and the push plate 19 moves in the adjustment groove 18 through the sliding of the two sets of arc panels 24. When the limit straight rod 26 on the push plate 19 slides to the top of the limit circular hole 28, push the limit straight rod 26 downward so that the bottom end of the limit straight rod 26 is inserted into the inside of the limit circular hole 28 through the push plate 19, and the transmission shaft 20 drives the driven gear 21 and the driving gear through the sliding of the push plate 19. 17 are meshed with each other, at which time the transmission frame 22 is just clamped in the transmission groove 23 on the sampling drill bit 6, the driving motor 16 is started so that the output shaft on the driving motor 16 drives the driving gear 17 to start rotating, and the driven gear 21 drives the transmission frame 22 to rotate by meshing with the driving gear 17, and the disc 11 synchronously follows the sampling drill bit 6 to rotate between the two groups of clamping blocks 10, preventing the sampling drill bit 6 from shifting forward and backward during the rotation process, so that the rotation of the sampling drill bit 6 is more stable, and the sampling drill bit 6 is connected to the transmission frame 23 through the transmission groove 23. 2 is clamped in the ring sleeve 8 to rotate and sample the rock and soil. When the sampling drill bit 6 needs to be stored, the limiting straight rod 26 is first pulled upward to make the limiting straight rod 26 disengage from the limiting circular hole 28, and then the push plate 19 is slid to the initial position to disengage the driven gear 21 from the driving gear 17, so that the transmission frame 22 is disengaged from the transmission groove 23, and the slide bar 13 is pulled outward of the adjustment disk 12. During the sliding process of the slide bar 13 on the adjustment disk 12, the limiting gasket 15 is driven to slide to squeeze the reset spring. 14 is compressed and shortened until the end of the slide bar 13 is separated from the side of the side protection plate 5, and then the adjusting disk 12 is rotated ninety degrees. The side shaft 7 drives the sampling drill bit 6 to rotate ninety degrees through the rotation of the adjusting disk 12, and the end of the sampling drill bit 6 corresponding to the transmission groove 23 is rotated into the empty groove 3. When the slide bar 13 is rotated to the groove position, the slide bar 13 is relaxed and the rebound force of the reset spring 14 is used to make the limit gasket 15 drive the end of the slide bar 13 to be inserted into the groove, so as to prevent the sampling drill bit 6 from shaking when the geotechnical sampling vehicle 1 is driving.
