Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering survey equipment, in particular to a geotechnical core sample storage device. Background Art

[0002] Drilling and core sampling is the basis of geotechnical engineering investigation work. Good preservation of on-site core samples is very important for on-site investigation and identification of geotechnical properties. After the core samples are taken out from the rock and soil boreholes through the geotechnical sampling device, the rock and soil core samples need to be stored through a storage device.

[0003] A geotechnical engineering core sample storage mechanism disclosed in Chinese patent CN217731180U prevents core samples from scattering due to collision during transportation, which is beneficial to the later data collection of core samples. However, while solving the problem, the geotechnical engineering core sample storage mechanism has the following disadvantages:

[0004] 1. When taking out the rock and soil core sample fixed between the two curved clamping plates, the two curved clamping plates need to be pulled to both sides to take out the rock and soil core sample, which is inconvenient to operate;

[0005] 2. When fixing the two ends of rock and soil core samples of different lengths, it is necessary to adjust the distance between the two movable plates separately, and the adjusted distance between the two movable plates is limited by the positioning holes, so that the distance between the two movable plates cannot be adjusted arbitrarily, which is relatively impractical. Utility Model Content

[0006] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0007] Therefore, one purpose of the utility model is to provide a rock and soil core sample storage device to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0008] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a rock and soil core sample storage device, including a box body, the interior of the box body is fixedly connected to a placing table, the top of the box body is rotatably connected to a box cover, the top of the box cover is threadedly connected to a first driving screw, the bottom end of the first driving screw is rotatably connected to a movable plate, the top of the movable plate is movably connected to a first limiting column, and the bottom end of the first limiting column is fixedly connected to an arc-shaped clamping plate.

[0009] Preferably, any of the above schemes is that an arc-shaped placement groove is opened on the top of the placement table, and the arc-shaped placement groove corresponds to the arc-shaped clamping plate. A spring is arranged on the outer side of the first limiting column. The arc-shaped clamping plate can move downward under the drive of the moving column and the limiting column and clamp the rock and soil core sample placed in the arc-shaped placement groove. The setting of the spring enables the arc-shaped clamping plate to better fix the rock and soil core sample.

[0010] Preferably, any of the above schemes is that a second driving screw is threadedly connected to the inner wall on the other side of the arc-shaped placement groove, one end of the second driving screw is rotatably connected to a second rubber clamp, and a limiting groove is provided on the inner wall of the arc-shaped placement groove. The rotation of the second driving screw can drive the second rubber clamp to move and can clamp and fix one end of rock and soil core samples of different lengths, and a second driving screw is provided on one side of each of the arc-shaped placement grooves, thereby improving the practicability of the device.

[0011] Preferably, any of the above schemes has a large gap between the four sides of the placement table and the inner wall of the box body, and a plurality of arc-shaped placement grooves are symmetrically arranged on the placement table. The gap between the placement table and the box body facilitates the rotation of the second driving screw.

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] 1. By rotating the first screw rod, the movable plate moves upward, so that the movable plate can drive all the arc-shaped clamping plates to be removed from the upper side of the rock and soil core sample, so that after the box cover is opened, only the second driving screw rod needs to be rotated to take the rock and soil core sample out from the inside of the arc-shaped placement groove, and the whole operation is relatively convenient.

[0014] 2. A second driving screw is provided on one side of each arc-shaped placement groove. The second rubber clamp on the second driving screw cooperates with the first rubber clamp to fix the two ends of the rock and soil core sample. When fixing, no matter the length of the rock and soil core sample, it is only necessary to rotate the second driving screw, which is highly practical.

When the rock and soil core sample placed in the box body 1 is taken out, the first driving screw 4 is rotated, and the first driving screw 4 drives the movable plate 5 to move downward, and the movable plate 5 drives the arc-shaped clamping plate 7 to move upward through the first limiting column 6, so that the upper sides of all the rock and soil core samples placed on the placing table 2 are no longer fixed by the arc-shaped clamping plates 7.

[0025] Embodiment 1: A second limiting column 8 is fixedly connected to the top of the movable plate 5, and the second limiting column 8 is movably connected to the box cover 3. When the movable plate 5 moves inside the box body 1, it drives the second limiting column 8 to move on the box cover 3. The setting of the second limiting column 8 enables the first driving screw 4 to drive the movable plate 5 to move so that the movable plate 5 can move up and down in a straight line.

[0026] Embodiment 2: An arc-shaped placement groove 9 is provided on the top of the placement table 2, and the arc-shaped placement groove 9 corresponds to the arc-shaped clamping plate 7. A spring 10 is provided on the outer side of the first limiting column 6, and the spring 10 pushes the arc-shaped clamping plate 7 downward through the first limiting column 6. When fixing the outer side of the rock and soil core sample inside the arc-shaped placement groove 9, the box cover 3 is covered, and then the movable plate 5 is driven to move downward by the first driving screw, so that the movable plate 5 pushes the arc-shaped clamping plate 7 to move downward through the first limiting column 6 and the spring 10, so that the arc-shaped clamping plate 7 cooperates with the arc-shaped placement groove 9 to complete the fixation of the rock and soil core sample.

[0027] Embodiment 3: A fixed cylinder 11 is fixedly connected to the inner wall of the arc-shaped placement groove 9, a moving rod 12 is movably connected inside the fixed cylinder 11, one end of the moving rod 12 is fixedly connected to a first rubber clamp 13, a spring is arranged inside the fixed cylinder 11, the moving rod 12 is connected to the fixed cylinder 11 through the spring, and when the rock and soil core sample is fixed, the rock and soil core sample is placed inside the arc-shaped placement groove 9 and one end of the rock and soil core sample is in contact with the first rubber clamp 13.

[0028] Embodiment 4: A second driving screw 14 is threadedly connected to the inner wall on the other side of the arc-shaped placement groove 9, and one end of the second driving screw 14 is rotatably connected to the second rubber clamp 15. A limiting groove 16 is provided on the inner wall of the arc-shaped placement groove 9. The second driving screw 14 is connected to the second rubber clamp 15 through a bearing. The second rubber clamp 15 is provided with a limiting block corresponding to the limiting groove 16. The limiting block can move inside the limiting groove 16, so that when the second driving screw 14 pushes the second rubber clamp 15, the second rubber clamp 15 will not rotate with the second driving screw 14. By rotating the second driving screw 14, the second driving screw 14 pushes the second rubber clamp 15 to move and contact with the other end of the rock and soil core sample, and at the same time cooperates with the first rubber clamp 13 to complete the fixation of the two ends of the rock and soil core sample.

[0029] Embodiment 5: There are large gaps between the four sides of the placement table 2 and the inner wall of the box body 1. The placement table 2 is symmetrically provided with a plurality of arc-shaped placement grooves 9. The arc-shaped placement grooves 9 are symmetrically provided with two sides, and a second driving screw 14 is provided on one side of each arc-shaped placement groove 9.

[0030] Embodiment 6: A snap ring 17 is rotatably connected to the front of the box body 1, and a clamping block 18 is fixedly connected to the front of the box cover 3. The snap ring 17 can be rotated onto the clamping block 18, so that the stability of the box cover 3 when it is on the top of the box body 1 can be guaranteed.

[0031] The working principle of the utility model is as follows: when in use, when fixing the rock and soil core sample, the rock and soil core sample is placed inside the arc placement groove 9, and the corresponding second driving bolt 14 is rotated, so that the second driving bolt 14 pushes the second rubber clamping plate 15 to move inside the arc placement groove 9 and cooperates with the first rubber clamping plate 13 to complete the fixation of the rock and soil core sample. After all the rock and soil core samples are placed inside the arc placement groove 9 and the fixation of both ends is completed, the box cover 3 is rotated so that the box cover 3 covers the box body 1, and then the box cover 3 is fixed by the clamping ring 17 and the clamping block 18, and finally the first driving screw 4 is rotated so that the first driving screw 4 pushes the movable plate 5 to move downward, and the movable plate 5 pushes the arc clamping plate 7 to move downward through the first limiting column 6 and the spring 10, so that the arc clamping plate 7 completes the fixation of the outer side of the rock and soil core sample inside the arc placement groove 9. When the rock and soil core sample is taken out, the above operation can be performed in reverse.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When taking out the rock and soil core sample stored in the box body 1, first rotate the first driving screw 4 so that the first driving screw 4 drives the movable plate 5 to move upward, so that the movable plate 5 drives all the arc-shaped clamping plates 7 to move upward through the first limiting column 6, so that the arc-shaped clamping plates 7 are no longer fixed on the outside of the rock and soil core sample placed on the placement table 2, and then open the box cover 3, and rotate the second driving screw 14 corresponding to one side of the rock and soil core sample so that the two rubber clamping plates are no longer fixed on the two ends of the rock and soil core sample, and then take out the rock and soil core sample from the inside of the arc-shaped placement groove 9. The whole operation process only requires rotating the first driving screw 4 and the second driving screw 14, and the operation is relatively convenient.

[0034] 2. The arc-shaped placement grooves 9 on the placement table 2 are symmetrically arranged in two rows, so that a second driving bolt 14 is arranged on one side of each arc-shaped placement groove, and the second driving bolt 14 is relatively long, so that when fixing the two ends of the rock and soil core sample inside the arc-shaped placement groove 9, regardless of the length of the rock and soil core sample, the second driving bolt 14 can be normally rotated, so that the second rubber clamp 15 on the second driving bolt 14 cooperates with the first rubber clamp 13 to complete the fixation of the two ends of the rock and soil core sample, and the setting of the second driving bolt 14 makes the moving distance of the second rubber clamp 15 not limited, and the above setting improves the practicability of the device.
