Description

Technical Field

[0001] The invention belongs to the field of geotechnical earthquake engineering, and in particular relates to a vibration table sample making device. Background Art

[0002] The earthquake simulation shaking table test can realize various forms of seismic wave input and simulate the whole process of several earthquakes of different magnitudes. It is the most direct indoor test to study the seismic response law and failure mechanism of slopes, and can restore the earthquake process more realistically. Due to its many advantages such as high restoration degree and strong reliability, a large number of scholars at home and abroad have adopted the shaking table test to study the seismic performance and seismic response of slopes. The design and production of the model box is a very important part of the slope shaking table test, which plays a vital role in the accuracy of the conclusion of the dynamic response of the real slope under the action of earthquake. Different types of rigid model boxes have revealed a large number of laws of the dynamic response of slopes under earthquake excitation. At present, the layered slope production in the shaking table test usually adopts the layer-by-layer compaction method. This method will cause the slope density to gradually increase from the top to the bottom, and the overall density of the slope is inconsistent, which cannot simulate the seismic dynamic response of the real slope. Therefore, in order to better study this problem, a device that can both stack layered slopes and ensure their consistent density is needed.

[0003] Layered slopes are one of the most common slopes in nature, and studying their dynamic response laws is of great significance for evaluating the stability of slopes. In the prior art, the test device and the modeling device are independent of each other. When the model is transferred to the experimental device after manufacturing, it is easy to shake, causing the model to loosen, which in turn leads to uneven density at different elevations of the slope model. Summary of the invention

[0004] In view of the above problems, an embodiment of the present application provides a vibration table sample preparation device, which can reduce the risk of uneven density inside the sample caused by shaking when the sample is transferred and stacked.

[0005] The embodiment of the present application provides a vibration table sample making device, which includes a trimming frame, a storage frame, a first bottom plate, a second bottom plate, and an adjustment component. The trimming frame has a trimming cavity for trimming the sample; the storage frame is located below the trimming frame, and the storage frame has a storage cavity for accommodating the sample; the first bottom plate is between the trimming frame and the storage frame in the direction of gravity, and the first bottom plate moves relative to the trimming frame along a first direction so that the storage cavity and the trimming cavity are separated or connected, and the first direction is perpendicular to the direction of gravity; wherein the vibration table sample making device also includes a second bottom plate and an adjustment component, the second bottom plate is arranged in the storage cavity, and the adjustment component is configured to drive the second bottom plate to move along the direction of gravity.

[0006] Specifically, during use, the shaping cavity and the storage cavity are first isolated by the first bottom plate, and then the second bottom plate is adjusted to abut against the first bottom plate through the adjustment component, and then the sample is shaped in the shaping cavity and pressurized to form a single-layer slope sample, and then the first bottom plate is slid along the first direction to connect the shaping cavity and the storage cavity, so that the single-layer slope sample falls on the second bottom plate, and then the second bottom plate is driven to descend to the height of the single-layer slope sample through the adjustment component.

[0007] Slide the first bottom plate along the first direction to isolate the shaping cavity and the storage cavity, then shape the sample in the shaping cavity, pressurize to form a single-layer height slope sample, slide the first bottom plate in the first direction to connect the shaping cavity and the storage cavity, and make the single-layer height slope sample fall on the previously completed slope sample, apply the same pressure to eliminate the gap between adjacent samples, and repeat in sequence to form multi-layer height slope samples. In this process, the multi-layer slope tests are pressurized and formed in sequence, so the density of the slope model at different elevations is consistent. At the same time, there is no need to disassemble and assemble the storage cavity, the operation is simple, and the time for sample preparation is reduced. It also reduces the shaking of the samples when different layers of samples are stacked, and reduces the risk of uneven density inside the samples due to shaking when the samples are transferred and stacked.

[0008] In some embodiments, there are multiple storage frames arranged in sequence along the direction of gravity, and the storage frames are configured to have a first position and a second position in a first direction. On a plane perpendicular to the direction of gravity, the orthographic projection of the storage cavity of the storage frame located at the first position and the orthographic projection of the storage frame located at the second position have a first overlapping area, and the orthographic projection of the storage cavity of the storage frame located at the first position overlaps with the orthographic projection of the trimming frame.

[0009] Specifically, during use, the topmost storage frame is first moved to the first position, and the remaining storage frames are located at the second position. After the first layer of sample preparation is completed, the second bottom plate is driven down by the adjustment component so that the second bottom plate abuts against the storage frame adjacent to the topmost storage frame, thereby lowering the second bottom plate by the height of the single-layer slope sample, and at the same time, the storage frame adjacent to the topmost storage frame can cooperate with the adjustment component to support the second bottom plate, and then the adjacent storage frame is moved to the first position so that the second bottom plate no longer abuts against the adjacent storage frame, and the storage cavities in the adjacent storage frames overlap along the gravity direction, so that the second bottom plate slides into the adjacent storage cavity. This process is repeated until all storage frames are filled with samples.

[0010] On the one hand, the stress condition of the adjusting component is improved and the service life of the adjusting component is extended; on the other hand, the descending height of the adjusting component is limited by the adjacent storage frame, and the structure is simple and easy to implement.

[0011] In some embodiments, the adjustment assembly includes a bracket, a first substrate, and a driving member. The first substrate is detachably arranged on the top of the bracket, a plurality of storage frames are arranged on a side of the first substrate away from the bracket, a first opening is opened on the first substrate, and the orthographic projection of the first opening is located in the first overlapping area on a plane perpendicular to the direction of gravity; one end of the driving member is arranged on the bracket, and the other end passes through the first opening and is detachably connected to the second bottom plate, and the driving member is used to drive the second bottom plate to move along the direction of gravity.

[0012] In the above technical solution, the first substrate is detachably arranged on the top of the bracket, and the other end of the driving member passes through the first opening and is detachably connected to the second bottom plate. Therefore, after the sample is made, the first substrate can be removed from the bracket to facilitate moving the storage frame by moving the first substrate.

[0013] In some embodiments, the adjustment component further includes a first pillar, which is disposed on a side of the first substrate away from the bracket and extends along the direction of gravity, and the storage frame is slidably disposed on the first pillar along a first direction.

[0014] In some embodiments, the first pillars are a plurality of pairs spaced apart along a first direction, and each pair of first pillars is two spaced apart along a second direction on opposite sides of the storage frame; the plurality of pairs of first pillars include a pair of first middle pillars, the first middle pillars having a first side surface in the first direction, the first side surface being flush with a side surface of the storage frame at the first position facing the second position; the adjustment assembly also includes a first limit member, the first limit member is detachably disposed on the first side surface, and the first limit member is used to abut against the storage frame to limit the storage frame to the first position.

[0015] In the above technical solution, the first limiting member enables the storage frames to be located at the first position, so as to reduce the possibility that the storage frames slide during the sample preparation process, causing the test to be damaged by shear force.

[0016] In some embodiments, the trimming frame includes a first frame body and a first side plate. The first frame body has a trimming cavity, and the first frame body has a second opening on one side in the first direction; the first side plate is used to block the second opening, and the first side plate is configured to move relative to the first frame body along the first direction to adjust the size of the trimming cavity in the first direction.

[0019] In the above technical solution, by sliding the second side plate along the first direction, the storage cavity can accommodate samples with different sizes in the first direction, and the structure is simple and easy to implement.

[0020] In some embodiments, the trimming frame also includes a trimming plate, which is configured to be slidable in the second direction and arranged in the storage cavity to adjust the size of the trimming cavity in the second direction. The trimming plate is configured to be rotatable around a first axis, the first axis is parallel to the first direction, and the first direction, the second direction and the direction of gravity are perpendicular to each other.

[0021] In the above technical solution, the trimming plate is provided to manufacture samples with different slopes, and the structure is simple and easy to implement.

[0022] In some embodiments, the first bottom plate is made of a transparent material.

[0023] In the above technical solution, by setting the first bottom plate with a transparent material, the area of ​​the sample below can be referred to when making the slope, so that the sample on the upper layer can fall more closely on the sample on the lower layer.

[0024] In some embodiments, the second base plate includes a sub-base plate and a connecting member. The sub-base plates are arranged in a plurality along the first direction; and the connecting member is used to connect the plurality of sub-base plates.

[0025] In the above technical solution, by setting the second sub-plate as a split structure of multiple sub-base plates, the operator can select the number of sub-base plates according to the size of the sample in the first direction so that the second base plate can adapt to samples with different sizes in the first direction.

[0048] The earthquake simulation shaking table test can realize various forms of seismic wave input and simulate the whole process of several earthquakes of different magnitudes. It is the most direct indoor test to study the seismic response law and failure mechanism of slopes, and can restore the earthquake process more realistically. Due to its many advantages such as high restoration degree and strong reliability, a large number of scholars at home and abroad have adopted the shaking table test to study the seismic performance and seismic response of slopes. The design and production of the model box is a very important part of the slope shaking table test, which plays a vital role in simulating the accuracy of the dynamic response conclusion of the real slope under the action of earthquake. Different types of rigid model boxes have revealed a large number of dynamic response laws of slopes under seismic excitation. At present, the production of layered slopes in shaking table tests usually adopts the layer-by-layer compaction method. This method will cause the slope density to gradually increase from the top to the bottom, and the overall density of the slope is inconsistent, which cannot simulate the seismic dynamic response of the real slope. Therefore, in order to better study this problem, a device that can both stack layered slopes and ensure their consistent density is needed. Layered slopes are one of the most common slopes in nature. Studying their dynamic response laws is of great significance to the stability evaluation of slopes. In the prior art, the test device and the model making device are independent of each other. When the model is transferred to the test device after manufacturing, it is easy to shake, causing the model to loosen, which in turn leads to uneven density at different elevations of the slope model.

[0049] In order to solve the above technical problems, refer to Figure 1-Figure 6The embodiment of the present application provides a vibration table sample making device 1000, which includes a trimming frame 100, a storage frame 200, a first bottom plate 300, a second bottom plate 400 and an adjustment component 500. The shaping frame 100 has a shaping cavity 101 for shaping the sample; the storage frame 200 is located below the shaping frame 100, and the storage frame 200 has a storage cavity 201 for accommodating the sample; the first bottom plate 300 is between the shaping frame 100 and the storage frame 200 in the gravity direction Z, and the first bottom plate 300 moves along the first direction X relative to the shaping frame 100, so that the storage cavity 201 and the shaping cavity 101 are separated or connected, and the first direction X is perpendicular to the gravity direction Z; wherein, the vibration table sample making device 1000 also includes a second bottom plate 400 and an adjustment component 500, the second bottom plate 400 is arranged in the storage cavity 201, and the adjustment component 500 is configured to drive the second bottom plate 400 to move along the gravity direction Z.

[0050] It can be understood that the trimming frame 100 can be detachably disposed on the storage frame 200 by bolt connection.

[0051] In some embodiments, there is a gap between the trimming frame 100 and the storage frame 200 in the gravity direction Z, and the first bottom plate 300 is inserted in the gap to separate the trimming cavity 101 and the storage cavity 201 .

[0052] It should be noted that the thickness of the first bottom plate 300 should be reduced as much as possible to reduce the distance that the sample falls when the first bottom plate 300 is removed. For example, the first bottom plate 300 can be made of a plate with a thickness of 1-3 mm.

[0053] In some embodiments, please refer to Figure 2 The wall of the storage frame 200 is provided with a first slide groove 2121 extending along the gravity direction Z, and the second bottom plate 400 is provided with a first slider 412 adapted to the first slide groove 2121. The first slider 412 is slidably arranged in the first slide groove 2121. For example, the first slide groove 2121 is a dovetail groove, and the first slider 412 is a dovetail block adapted thereto. It can be understood that after the second bottom plate 400 slides over the first slide groove 2121, the rubber adapted to the first slide groove 2121 can be used to fill the part of the second bottom plate 400 that slides over the first slide groove 2121 along the gravity direction Z.

[0054] For details, please refer to Figure 3 and Figure 4During use, the shaping cavity 101 and the storage cavity 201 are first isolated by the first bottom plate 300, and then the second bottom plate 400 is adjusted to abut against the first bottom plate 300 through the adjustment component 500, and then the sample is shaped in the shaping cavity 101 and pressurized to form a single-layer slope sample, and then the first bottom plate 300 is slid along the first direction X to connect the shaping cavity 101 and the storage cavity 201, so that the single-layer slope sample falls on the second bottom plate 400, and then the second bottom plate 400 is driven to descend the height of the single-layer slope sample through the adjustment component 500.

[0055] Please refer to Figure 5 and Figure 6 Slide the first bottom plate 300 along the first direction X to isolate the shaping cavity 101 and the storage cavity 201, then shape the sample in the shaping cavity 101, pressurize to form a single-layer height slope sample, slide the first bottom plate 300 in the first direction X to make the shaping cavity 101 and the storage cavity 201 connected, and make the single-layer height slope sample fall on the previously completed slope sample, apply the same pressure to eliminate the gap between adjacent samples, and repeat in sequence to form multi-layer height slope samples. In this process, the multi-layer slope test is pressurized and formed in sequence, so the density of the slope model at different elevations is consistent. At the same time, there is no need to disassemble and assemble the storage cavity 201, the operation is simple, and the time for sample preparation is reduced. It also reduces the shaking of the sample when different layers of samples are stacked, and reduces the risk of uneven density inside the sample due to shaking when the sample is transferred and stacked.

[0056] In some embodiments, please refer to Figure 6 , a second limiting hole 411 is provided on the second bottom plate 400 and penetrates the second bottom plate 400 along the vertical gravity direction Z, a first limiting hole 2111 corresponding to the second limiting hole 411 is provided on the frame wall of the storage frame 200, and the storage frame 200 further includes a second limiting member 230. When the second limiting hole 411 is aligned with the first limiting hole 2111 of the storage frame 200 where the second bottom plate 400 is located, the second limiting member 230 can be inserted into the first limiting hole 2111 and the second limiting hole 411 in sequence to fix the second bottom plate 400. Exemplarily, the second limiting hole 411 can penetrate the second bottom plate 400 along the first direction X, and the second limiting hole 411 can be a plurality of holes spaced apart along the second direction Y. The first direction X, the second direction Y, and the gravity direction Z are perpendicular to each other.

[0057] According to some embodiments of this application, please refer to Figure 7-Figure 9The storage frames 200 are multiple and are sequentially arranged along the gravity direction Z. The storage frames 200 are configured to have a first position and a second position in the first direction X. On a plane perpendicular to the gravity direction Z, the orthographic projection of the storage cavity 201 of the storage frame 200 located at the first position and the orthographic projection of the storage frame 200 located at the second position have a first overlapping area, and the orthographic projection of the storage cavity 201 of the storage frame 200 located at the first position overlaps with the orthographic projection of the trimming frame 100.

[0058] In some embodiments, please refer to Fig.13 , a portion of the first slider 412 protrudes from the plane of the second bottom plate 400 for carrying the sample along the gravity direction Z. When the second bottom plate 400 abuts against the adjacent storage frame 200, the portion of the first slider 412 is located in the first slide groove 2121 in the storage frame 200 where the second bottom plate 400 is located. Figure 2 A first avoidance groove 2123 extending along the first direction X is provided at the top of the storage frame 200 , and the avoidance groove is used to avoid the first sliding block 412 when the adjacent storage frame 200 moves along the first direction X.

[0059] In some embodiments, the storage frame 200 has two second walls 212 disposed opposite to each other in the second direction Y, and a plurality of first slide grooves 2121 are disposed at intervals on the inner surface of the second wall 212 along the first direction X. On a plane perpendicular to the gravity direction Z, the orthographic projection of any first slide groove 2121 when the storage frame 200 is in the second position does not overlap with the orthographic projection of any first slide groove 2121 when the storage frame 200 is in the second position, so that the second walls 212 of adjacent storage frames 200 can support the first slider 412 along the gravity direction Z, and further support the second bottom plate 400.

[0060] In some embodiments, the storage frame 200 has a first wall 211 in the second direction Y, and on a plane perpendicular to the gravity direction Z, the orthographic projection of the first wall 211 of the storage frame 200 located at the second position overlaps with the orthographic projection of the second bottom plate 400 of the storage frame 200 located at the first position, so that the first wall 211 can support the second bottom plate 400 along the gravity direction Z.

[0061] Specifically, during use, the topmost storage frame 200 is first moved to the first position, and the remaining storage frames 200 are located at the second position. After the first layer of sample preparation is completed, the second bottom plate 400 is driven to descend by the adjustment component 500, so that the second bottom plate 400 abuts against the storage frame 200 adjacent to the topmost storage frame 200, thereby causing the second bottom plate 400 to descend by the height of the single-layer slope sample, and at the same time, the storage frame 200 adjacent to the topmost storage frame 200 can cooperate with the adjustment component 500 to support the second bottom plate 400, and then the adjacent storage frame 200 is moved to the first position, so that the second bottom plate 400 and the adjacent storage frame 200 are no longer abutted, and the storage cavities 201 in the adjacent storage frames 200 overlap along the gravity direction Z, so that the second bottom plate 400 slides into the adjacent storage cavity 201. This reciprocating process is repeated until all storage frames 200 are filled with samples.

[0062] On the one hand, the stress condition of the adjusting component 500 is improved and the service life of the adjusting component 500 is extended; on the other hand, the descending height of the adjusting component 500 is limited by the adjacent storage frame 200, and the structure is simple and easy to implement.

[0063] According to some embodiments of this application, please refer to Figure 1 and Fig.12 The adjustment assembly 500 includes a bracket 510, a first substrate 520 and a driving member 530. The first substrate 520 is detachably arranged on the top of the bracket 510, and a plurality of storage frames 200 are arranged on a side of the first substrate 520 away from the bracket 510. A first opening 521 is provided on the first substrate 520, and the orthographic projection of the first opening 521 is located in the first overlapping area on a plane perpendicular to the gravity direction Z; one end of the driving member 530 is arranged on the bracket 510, and the other end passes through the first opening 521 and is detachably connected to the second bottom plate 400, and the driving member 530 is used to drive the second bottom plate 400 to move along the gravity direction Z.

[0064] In some embodiments, reference Fig.12 The bracket 510 includes a second base plate 511, the second base plate 511 is used to abut against the ground, and a second support 512 is provided on the side of the second base plate 511 away from the ground. The second support 512 extends along the gravity direction Z and is a plurality of second support pillars 512 arranged around the second base plate 511 at intervals. The driving member 530 is provided in the plurality of second support pillars 512.

[0065] In some embodiments, the driving member 530 can be a gas spring, which is mainly composed of a piston rod, a piston, a sealing guide sleeve, a filler, a pressure cylinder and a joint, wherein the pressure cylinder is a closed cavity filled with an inert gas or an oil-gas mixture, and the pressure in the cavity is several times or dozens of times the atmospheric pressure. When the gas spring is in action, the pressure difference on both sides of the piston is used to achieve the movement of the piston rod. Gas springs have different structures and types to meet different usage requirements. Compression gas springs are mainly used in engineering machinery. This type of gas spring mainly plays a supporting role and has only two working positions, the shortest and the longest, and cannot stop by itself during the stroke.

[0066] Specifically, during use, when the second bottom plate 400 is unloaded, the weak pressure side of the gas spring is connected to the outside world, and the gas spring is released to stretch, so as to drive the second bottom plate 400 to move along the gravity direction Z toward the first bottom plate 300 until the second bottom plate 400 abuts against the first bottom plate 300, and the gas spring stops stretching. When the first bottom plate 300 is pulled out and the sample falls on the second bottom plate 400, the weak pressure side of the gas spring is connected to the outside world. At this time, the gas spring is compressed and gradually shortened until the second bottom plate 400 abuts against the adjacent storage frame 200 located in the second position along the gravity direction Z. The weak pressure side of the gas spring is disconnected from the outside world so that the gas spring can provide support force to the second bottom plate 400. Refer to Figure 8 and Fig. 9 At this time, the driving member 530, the first wall 211 of the adjacent storage frame 200 and the second limiting member 230 respectively support the opposite sides and the middle of the second bottom plate 400 in the first direction X, so that the force on the second bottom plate 400 is more uniform.
