Description

Technical Field

[0001] This utility model belongs to the technical field of rock core storage equipment for geotechnical engineering exploration, and in particular, relates to a sample storage box for geotechnical engineering exploration sampling. Background Technology

[0002] Core sampling, also known as core drilling sampling, is the sampling work carried out on rock cores or mineral cores obtained through drilling. Core samples are generally cylindrical and are used to analyze underground geological structures and rock properties, providing crucial geological data for engineering projects such as highway surveying and design, and bridge construction. Currently, to preserve the integrity of core samples during transportation and to prevent friction and collision between adjacent core samples, each core sample is typically held in a core sample storage box by two clamps. Because the distance between the two clamps is slightly larger than the diameter of the cylindrical core sample, it not only makes it difficult for workers to easily remove the core sample from the storage box, but also easily causes finger injuries to workers during the process of removing the core sample from the clamps.

[0021] Please refer to the following: Figures 1 to 8 The sample storage box for geotechnical engineering investigation provided in this embodiment will now be described. Please refer to the following for further details. Figure 1 , Figure 2 , Figure 3 and Figure 4 The geotechnical engineering sampling storage box provided in this embodiment includes a box body 1, a cover 2, a positioning component 3, a lifting component 4, a pressing component 5, and a locking component 6. The box body 1 has an internal cavity 11 for storing rock core samples, and the top of the box body 1 has a retrieval port 12 for taking out or inserting columnar rock core samples 7. The cavity 11 is connected to the retrieval port 12. The cover 2 is used to cover the top of the box body 1 to close the retrieval port 12. The cover 2 can be connected to the box body 1 by a snap-fit ​​structure, or it can be rotatably connected to the box body 1 by a hinge, etc. The positioning component 3 is used to position the columnar rock core sample 7 in the box 1. The positioning component 3 includes multiple strip-shaped positioning supports 31 arranged side by side and spaced apart along the width direction of the box 1, and slide rails 32 respectively located at both ends of each positioning support. The length direction of the slide rails 32 is parallel to the height direction of the cover 2. The box 1 is provided with a sliding groove 13 that cooperates with the slide rail 32. Each slide rail 32 is slidably installed in the corresponding sliding groove 13 so that the strip-shaped positioning supports 31 can move up and down along the height direction of the box 1. Each strip-shaped positioning support 31 is recessed with a first positioning groove 311 for accommodating and positioning the columnar rock core sample 7. By placing the columnar rock core sample 7 in the first positioning groove 311, the columnar rock core sample 7 can be positioned in the box 1 by the strip-shaped positioning supports 31, preventing the columnar rock core sample 7 from rolling or colliding. A lifting assembly 4 is located between the bottom surface of the strip positioning bracket 31 and the inner bottom surface of the housing 1. The lifting assembly 4 is used to push the strip positioning bracket 31 against the loading / unloading port 12 at the top of the housing 1, so that the columnar rock core sample 7 on the strip positioning bracket 31 can be moved out of the housing 1 through the loading / unloading port 12. A pressing member 5 is located on the cover 2. The pressing member 5 is used to press the strip positioning bracket 31 against the inner bottom surface of the housing 1, so that the columnar rock core sample 7 on the strip positioning bracket 31 is received into the receiving cavity 11 through the loading / unloading port 12. A locking assembly 6 is used to lock the cover 2 onto the housing 1. The locking assembly 6 is located on the cover 2 / or the housing 1.

[0022] The working and usage process of the geotechnical engineering investigation sampling sample storage box provided in this embodiment of the utility model is as follows: Please refer to the following: Figure 1 and Figure 2 Columnar rock core samples 7 are placed in the first positioning grooves 311 on each of the strip positioning supports 31. The lifting assembly 4 pushes against the openings 12 on the top of the box 1 of each strip positioning support 31, allowing the columnar rock core samples 7 on each strip positioning support 31 to be moved out of the box 1 through the openings 12. Then, the cover 2 is placed on top of the box 1, and the cover 2 is pressed down forcefully. The cover 2, along with the pressing member 5 on it, presses against the inner bottom surface of each strip positioning support 31 towards the box 1, thus counteracting the pressure exerted by the lifting assembly 4 on the inner bottom surface of each strip positioning support 31. The top of the box 1 exerts a pushing force, causing each strip positioning bracket 31 and the columnar rock core sample 7 on each strip positioning bracket 31 to move downwards along the height direction of the box 1. This allows the columnar rock core sample 7 on each strip positioning bracket 31 to gradually move down through the loading / unloading port 12 and be stored in the receiving cavity 11 until the cover 2 is fully closed with the box 1. At this point, the columnar rock core sample 7 on each strip positioning bracket 31 is completely stored in the receiving cavity of the box 1. The cover 2 can then be locked onto the box 1 by the locking component 6, thus completing the storage of the columnar rock core sample 7. Please refer to the following: Figure 7 and Figure 8 When it is necessary to remove the columnar rock core sample 7 for analysis and research, it is only necessary to release the locking component 6 from the lock of the cover 2 and the box 1, and move the pressing component 5 away from the top of the box 1 together with the cover 2. At this time, the lifting component 4 can push against the opening 12 of each strip positioning bracket 31 facing the top of the box 1. With the cooperation of the slide rail 32 and the slide groove 13, each strip positioning bracket 31 and the columnar rock core sample 7 on each strip positioning bracket 31 can move upward along the height direction of the box 1 until the columnar rock core sample 7 on each strip positioning bracket 31 can be moved out of the opening 12 to the outside of the box 1. Then the columnar rock core sample 7 can be pushed axially, so that the staff can easily and conveniently remove the columnar rock core sample 7 from the box 1, effectively avoiding the injury of the staff's fingers during the removal of the columnar rock core sample 7, and improving the safety of the removal and placement of the columnar rock core sample 7.

[0023] Compared with the prior art, the geotechnical engineering exploration sampling sample storage box provided in this embodiment of the utility model has multiple strip-shaped positioning supports 31 that can slide up and down along the height direction of the box body 1 in the receiving cavity 11 of the box body 1. The multiple strip-shaped positioning supports 31 are arranged side by side and spaced apart along the width direction of the box body 1. The columnar rock core sample 7 only needs to be placed in the first positioning groove 311 of the strip-shaped positioning support 31, and then the pressing member 5 on the cover 2 presses each strip-shaped positioning support 31 against the receiving cavity 11 of the box body 1. The cover 2 is locked to the box body 1 by the locking component 6, and the columnar rock core sample 7 can be stored. When it is necessary to remove the columnar rock core sample 7 from the box 1, simply move the pressing member 5 away from the top of the box 1 along with the cover 2. Use the lifting component 4 to push each strip positioning bracket 31 toward the pick-up and drop-off port 12 at the top of the box 1. With the cooperation of the slide rail 32 and the slide groove 13, each strip positioning bracket 31 can be guided to move upward along the height direction of the box 1. When the columnar rock core sample 7 on each strip positioning bracket 31 is moved out of the pick-up and drop-off port 12 to the outside of the box 1, the staff only needs to push the columnar rock core sample 7 axially to easily and conveniently remove the columnar rock core sample 7 from the box 1. This effectively avoids pinching fingers during the removal of the columnar rock core sample 7, thereby improving the convenience and safety of picking up and dropping the columnar rock core sample 7.

[0024] Please refer to the following: Figure 2 and Figure 4 In some embodiments, the lifting assembly 4 includes a plurality of first springs 41 and a plurality of second springs 42. The plurality of first springs 41 are arranged at equal intervals along the length direction of the strip positioning bracket 31. The first end of each first spring 41 is connected to the bottom surface of the strip positioning bracket 31, and the second end of each first spring 41 is connected to the inner bottom surface of the housing 1. The plurality of second springs 42 are arranged at equal intervals along the length direction of the strip positioning bracket 31. The first end of each second spring 42 is connected to the bottom surface of the strip positioning bracket 31, and the second end of each second spring 42 is connected to the inner bottom surface of the housing 1. In this embodiment, multiple first springs 41 and multiple second springs 42 are arranged at equal intervals along the length of the strip positioning bracket 31. The lifting assembly 4, composed of multiple first springs 41 and multiple second springs 42, can uniformly apply elastic force to the strip positioning bracket 31. On the one hand, during the process of removing the pressing member 5 and using the lifting assembly 4 to lift the strip positioning bracket 31, the multiple first springs 41 and multiple second springs 42 in a compressed state elastically press against the strip positioning bracket 31, which can ensure the stability of the upward sliding of the strip positioning bracket 31. On the other hand, when the pressing member 5 presses the strip positioning bracket 31 against the receiving cavity of the box 1, the compressed multiple first springs 41 and multiple second springs 42 can play a shock absorption and buffering role on the strip positioning bracket 31, which facilitates the transportation of columnar rock core samples 7 through the geotechnical engineering exploration sampling sample storage box provided in this embodiment of the utility model.

[0025] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, the lifting assembly 4 further includes a plurality of first columns 43 and a plurality of second columns 44 fixedly disposed in the receiving cavity 11. The plurality of first columns 43 are respectively disposed in correspondence with a plurality of first springs 41. The axial direction of each first column 43 is parallel to the height direction of the box 1. The strip positioning bracket 31 is provided with a plurality of first sliding holes 312 corresponding to the plurality of first columns 43. The bottom end of each first column 43 is fixedly connected to the inner bottom surface of the box 1. The top end of each first column 43 is slidably inserted into the corresponding first sliding hole 312. The sliding cooperation between each first column 43 and the corresponding first sliding hole 312 can guide the strip positioning bracket 31 to move up and down stably and accurately. On the other hand, it can enhance the stability of the strip positioning bracket 31 in positioning the columnar rock core sample 7 and prevent the strip positioning bracket 31 of a certain length from shaking and affecting the stability of the positioning of the columnar rock core sample 7. Each first spring 41 is fitted onto the corresponding first column 43, which can straighten the first spring 41 and prevent the first spring 41 from swaying during compression, thus affecting the stability of the columnar rock core sample 7 positioned by the strip positioning bracket 31.

[0026] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, multiple second columns 44 are correspondingly arranged with multiple second springs 42. The axial direction of each second column 44 is parallel to the height direction of the box 1. The strip positioning bracket 31 has multiple second sliding holes 313 corresponding to the multiple second columns 44. The bottom end of each second column 44 is fixedly connected to the inner bottom surface of the box 1, and the top end of each second column 44 is slidably inserted into the corresponding second sliding hole 313. Each second spring 42 is sleeved on the corresponding second column 44. The sliding cooperation between each second column 44 and the corresponding second sliding hole 313 can guide the strip positioning bracket 31 to move up and down stably and accurately. On the other hand, it can enhance the stability of the strip positioning bracket 31 in positioning the columnar rock core sample 7 and prevent the strip positioning bracket 31, which has a certain length, from shaking and affecting the stability of the columnar rock core sample 7. Each second spring 42 is fitted onto the corresponding second column 44, which can straighten the second spring 42 and prevent the second spring 42 from swaying during compression, thus affecting the stability of the columnar rock core sample 7 positioned by the strip positioning bracket 31.

[0027] Please refer to the following: Figure 3In some embodiments, in order to enhance the stability of the strip positioning bracket 31 in positioning the columnar rock core sample 7, the first sliding hole 312 and the second sliding hole 313 are respectively located on both sides of the first positioning groove 311 on the same strip positioning bracket 31, and the first sliding hole 312 and the second sliding hole 313 are arranged in a one-to-one correspondence, so that the first column 43 and the second column 44 guide and limit the strip positioning bracket 31 from both sides of the columnar rock core sample 7.

[0028] Please refer to the following: Figure 3 and Figure 8 In some embodiments, the first positioning groove 311 is an arc-shaped groove adapted to the outer peripheral surface of the columnar rock core sample 7. The depth of the first positioning groove 311 is less than or equal to the radius of the columnar rock core sample 7, which helps to increase the contact area between the columnar rock core sample 7 and the first positioning groove 311, so that the columnar rock core sample 7 can be stably positioned in the first positioning groove 311.

[0029] Please refer to the following: Figure 2 , Figure 5 and Figure 6 In some embodiments, the pressing member 5 is a compressible elastic pressing block made of silicone or rubber. The cover 2 is provided with a receiving groove 21 for accommodating and positioning the pressing member 5, and the pressing member 5 is installed in the receiving groove 21. In this embodiment, the pressing member 5 is pressed against the strip positioning bracket 31 and the columnar rock core sample 7 on the strip positioning bracket 31 by the cover 2. Since the pressing member 5 is a compressible elastic pressing block made of silicone or rubber, on the one hand, the pressing member 5 can make close contact with the outer peripheral surface of the columnar rock core sample 7 on the strip positioning bracket 31 to improve the positioning stability, and increase the friction between the pressing member 5 and the columnar rock core sample 7 to prevent the columnar rock core sample 7 from falling. On the other hand, it can play a shock-absorbing and buffering role for the columnar rock core sample 7 on the strip positioning bracket 31, which facilitates the transportation of the columnar rock core sample 7 through the geotechnical engineering exploration sampling sample storage box provided by this utility model embodiment.

[0030] Please refer to the following: Figure 5 and Figure 6In some embodiments, the pressing member 5 is provided with a second positioning groove 51 corresponding to the position of each first positioning groove 311. The depth of each second positioning groove 51 is less than or equal to the radius of the columnar rock core sample 7, which helps to increase the contact area between the columnar rock core sample 7 and the second positioning groove 51, so that the columnar rock core sample 7 can be stably positioned in the second positioning groove 51. The pressing member 5 is provided with a first positioning hole 52 and a second positioning hole 53 corresponding to the positions of each first column 43 and each second column 44. When the top end of each first column 43 is inserted into the corresponding first positioning hole 52 and the top end of each second column 44 is inserted into the corresponding second positioning hole 53, the stability of the strip positioning bracket 31 in positioning the columnar rock core sample 7 can be enhanced.

[0031] Please refer to the following: Figure 3 , Figure 5 and Figure 6 In some embodiments, the pressing member 5 is provided with a second positioning groove 51 corresponding to the position of each first positioning groove 311.

When the cover 2 is closed on the top of the box 1, each first positioning groove 311 and the corresponding second positioning groove 51 surround and define a cylindrical positioning cavity that can hold and limit the columnar rock core sample 7, so that the columnar rock core sample 7 can be stably contained and positioned in the cylindrical positioning cavity, which facilitates the transportation of the columnar rock core sample 7 through the geotechnical engineering exploration sampling sample storage box provided by this utility model embodiment.

[0032] Please refer to the following: Figure 3 , Figure 7 and Figure 7 In some embodiments, in order to enhance the stability of the strip positioning bracket 31 sliding up and down along the height direction of the box 1, each end of each strip positioning bracket 31 is provided with two slide rails 32. The two slide rails 32 are symmetrically arranged with the central axis of the first positioning groove 311 as the axis of symmetry. The box 1 is provided with a slide groove 13 corresponding to each slide rail 32 at the position of each slide rail 32.
