Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of active fault disaster effect simulation experiment, and particularly relates to a model box and a three-way servo cooperative control system thereof. BACKGROUND

[0002] In the process of researching the active fault disaster effect, the compressive strength is often used to represent the strength state of the rock and soil. The uniaxial compression process is used in the large model box, but the actual rock and soil has different force sizes in different directions during the stress process. Therefore, the large model box cannot accurately simulate the strength change of the object under the condition that the rock and soil is subjected to different forces in different directions. In order to restore the compression condition of the rock and soil as much as possible, the triaxial compression is an indispensable compression mode. However, the triaxial compression mode of the existing model box is to use a fixed confining pressure to measure the compressive strength of the rock and soil. The confining pressure cannot be accurately controlled during the compression process in different directions, and only a unified fixed confining pressure design can be used. The triaxial compression mode is only suitable for small model box mechanical test, and it is difficult to generate a large force in each direction. SUMMARY

DETAILED DESCRIPTION

[0031] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0032] The model box 1000 and the three-way servo cooperative control system thereof according to the embodiments of the present application are described below in conjunction with Figures 1 to 4

[0033] The first aspect of the present application proposes a model box 1000.

[0034] As shown in Figures 1 to 4 , the model box 1000 according to the first aspect of the present application is a large model box, which is used to simulate the strength change of an object under the condition that the rock-soil is subjected to different forces in different directions.

[0035] The model box 1000 according to the embodiments of the present application comprises a mounting seat 1, an enclosure 2, a pressurizing assembly 3 and a box body 4.

[0036] Specifically, the mounting seat 1 comprises two vertical plates 101 which are oppositely spaced left and right, i.e. the two vertical plates 101 are arranged at intervals in the left-right direction, and the mounting seat 1 forms a U-shaped groove with the opening facing upward between the two vertical plates 101, the U-shaped groove is through in the front-rear direction, and the two vertical plates 101 simultaneously function as a counterforce wall.

[0037] The enclosure 2 is arranged between the two vertical plates 101 and is in the shape of a rectangle, comprising an upper mounting portion 202, a front mounting portion 204, a lower mounting portion 203 and a rear mounting portion 205 which are sequentially connected in head-tail direction, and the enclosure 2 is through in the left-right direction.

[0038] The pressurizing assembly 3 comprises a plurality of first pressurizing pieces 301, a plurality of second pressurizing pieces 302, a plurality of third pressurizing pieces 303, a plurality of fourth pressurizing pieces 304 and a plurality of fifth pressurizing pieces 305. The plurality of first pressurizing pieces 301 are installed on one of the two vertical plates 101, as Figure 1 ​The plurality of first pressing members 301 are installed on the right standing plate 101 in the embodiment, but the plurality of first pressing members 301 can also be installed on the left standing plate 101; the plurality of second pressing members 302 are installed on the upper installation portion 202, the plurality of third pressing members 303 are installed on the lower installation portion 203, the plurality of fourth pressing members 304 are installed on the front installation portion 204, and the plurality of fifth pressing members 305 are installed on the rear installation portion 205.

[0039] The box body 4 is used for filling and placing the rock-soil sample, the box body 4 is located between the two standing plates 101 and passes through the enclosure 2 in the left-right direction, and the box body 4 abuts against the other standing plate 101 in the left-right direction, for example, Figure 1 If the plurality of first pressing members 301 are installed on the right standing plate 101 in the embodiment, the left side of the box body 4 abuts against the left standing plate 101, and if the plurality of first pressing members 301 are installed on the left standing plate 101, the right side of the box body 4 abuts against the right standing plate 101.

[0040] The plurality of first pressing members 301 are used to simultaneously apply pressure to the box body 4 in the left-right direction towards the other one of the two vertical plates 101, the plurality of second pressing members 302 are used to simultaneously apply pressure to the upper side of the box body 4 in the up-down direction, the plurality of third pressing members 303 are used to simultaneously apply pressure to the lower side of the box body 4 in the up-down direction, the plurality of fourth pressing members 304 are used to simultaneously apply pressure to the front side of the box body 4 in the front-back direction, and the plurality of fifth pressing members 305 are used to simultaneously apply pressure to the rear side of the box body 4 in the front-back direction. It can be understood that in the left-right direction, one of the left side and the right side of the box body 4 is applied with pressure by the plurality of first pressing members 301 arranged in parallel, and the total pressure that can be reached by combining the pressures applied by the plurality of first pressing members 301 is larger, so that one of the left side and the right side of the box body 4 is applied with larger pressure; similarly, in the up-down direction, the upper side of the box body 4 is applied with pressure by the plurality of second pressing members 302 arranged in parallel, and the total pressure that can be reached by combining the pressures applied by the plurality of second pressing members 302 is larger, so that the upper side of the box body 4 is applied with larger pressure, while the lower side of the box body 4 is also applied with pressure by the plurality of third pressing members 303 arranged in parallel, and the total pressure that can be reached by combining the pressures applied by the plurality of third pressing members 303 is larger, so that the lower side of the box body 4 is applied with larger pressure; again similarly, in the front-back direction, the front side of the box body 4 is applied with pressure by the plurality of fourth pressing members 304 arranged in parallel, and the total pressure that can be reached by combining the pressures applied by the plurality of fourth pressing members 304 is larger, so that the front side of the box body 4 is applied with larger pressure, while the rear side of the box body 4 is also applied with pressure by the plurality of fifth pressing members 305 arranged in parallel, and the total pressure that can be reached by combining the pressures applied by the plurality of fifth pressing members 305 is larger, so that the rear side of the box body 4 is applied with larger pressure; that is, the total pressures applied by the different sides of the box body 4 in three directions (here, the “three directions” refer to the left-right direction, the up-down direction and the front-back direction) can be different, by respectively controlling the sizes of the total pressures applied by the different sides of the box body 4, the rock-soil in the box body 4 is subjected to different forces in different directions, the compression state of the rock-soil can be restored, and the larger total pressures applied by the different sides of the box body 4 can be achieved, which is suitable for large-scale model box simulation experiments.

[0041] The model box 1000 according to the first aspect of the present application has the advantages that: the combination of forces is greatly strengthened by the plurality of first pressure devices 301, the plurality of second pressure devices 302, the plurality of third pressure devices 303, the plurality of fourth pressure devices 304, and the plurality of fifth pressure devices 305 arranged in parallel, the total pressure applied to different sides of the box body 4 is large, the possibility of different side limit pressures of different sides of the box body 4 can be simulated more, the restoration degree of the pressure condition in different states is increased, the control state of the force inside the model box 1000 is more accurate, the pressure condition of the rock and soil can be restored, and the model box 1000 is suitable for large-scale model simulation experiments.

[0042] In some embodiments, the number of the first pressure devices 301 is determined by the total pressure maximum limit value applied to the left side or the right side of the box body 4, the number of the second pressure devices 302 is determined by the total pressure maximum limit value applied to the upper side of the box body 4, the number of the third pressure devices 303 is determined by the total pressure maximum limit value applied to the lower side of the box body 4, the number of the fourth pressure devices 304 is determined by the total pressure maximum limit value applied to the front side of the box body 4, and the number of the fifth pressure devices 305 is determined by the total pressure maximum limit value applied to the rear side of the box body 4. Since the maximum pressure applied by a single first pressure device 301 is limited, the total pressure maximum limit value applied to the left side or the right side of the box body 4 is the sum of the maximum pressures applied by the plurality of first pressure devices 301, and then the number of the first pressure devices 301 can be reasonably determined, and the same applies to the number of the second pressure devices 302, the number of the third pressure devices 303, the number of the fourth pressure devices 304, and the number of the fifth pressure devices 305, which will not be described here.

[0043] In some embodiments, one end of the plurality of first pressure devices 301 is mounted on the inner side of the vertical plate 101 through a first plane bearing (not shown in the figure), and the other end of the plurality of first pressure devices 301 abuts against the left side or the right side of the box body 4 through a shared first thrust plate 3011. That is, each first pressure device 301 is arranged on the inner side of the vertical plate 101, i.e., in the U-shaped groove, and is reasonably arranged; each first pressure device 301 is mounted on the vertical plate 101 through a first plane bearing, so that the friction during the pressure action of the first pressure device 301 can be reduced; by arranging the first thrust plate 3011, the force applied to the left side or the right side of the box body 4 can be uniform.

[0044] In some embodiments, there are multiple surrounding frames 2, multiple second pressing members 302, multiple fourth pressing members 304, multiple fourth pressing members 304 and multiple fifth pressing members 305 are distributed on the multiple surrounding frames 2, and the second pressing member 302, the third pressing member 303, the third pressing member 303 and the fifth pressing member 305 are installed on each surrounding frame 2, the second pressing member 302 on each surrounding frame 2 is arranged symmetrically above and below the third pressing member 303, and the fourth pressing member 304 and the fifth pressing member 305 are arranged symmetrically in front and behind, and the arrangement is reasonable.

[0045] In some embodiments, the multiple surrounding frames 2 are the same, and the number and arrangement position of the first pressing member 301, the second pressing member 302, the third pressing member 303, the fourth pressing member 304 and the fifth pressing member 305 arranged on the multiple surrounding frames 2 are the same. That is, each surrounding frame 2 and the module unit formed by the first pressing member 301, the second pressing member 302, the third pressing member 303, the fourth pressing member 304 and the fifth pressing member 305 installed on the surrounding frame 2 are the same, and the processing is convenient.

[0046] In some embodiments, with respect to each surrounding frame 2, one end of all the second pressing members 302 is respectively installed on the inner side of the upper mounting portion 202 through a second plane bearing (not shown in the figure), and the other end of all the second pressing members 302 abuts against the upper side of the box body 4 through a shared second thrust plate; that is, the second pressing member 302 is arranged on the inner side of the upper mounting portion 202, which is reasonable, and by arranging the second plane bearing, the frictional resistance in the pressing action of the second pressing member 302 can be reduced, and by arranging the second thrust plate, the force applied to the upper side of the box body 4 can be evenly distributed.

[0047] One end of all the third pressing members 303 is respectively installed on the inner side of the lower mounting portion 203 through a third plane bearing (not shown in the figure), and the other end of all the third pressing members 303 abuts against the lower side of the box body 4 through a shared third thrust plate; that is, the third pressing member 303 is arranged on the inner side of the lower mounting portion 203, which is reasonable, and by arranging the third plane bearing, the frictional resistance in the pressing action of the third pressing member 303 can be reduced, and by arranging the third thrust plate, the force applied to the lower side of the box body 4 can be evenly distributed.

[0048] One end of all the fourth pressing members 304 is respectively installed on the inner side of the front mounting portion 204 through a fourth plane bearing (not shown in the figure), and the other end of all the fourth pressing members 304 abuts against the front side of the box body 4 through a shared fourth thrust plate; that is, the fourth pressing member 304 is arranged on the inner side of the front mounting portion 204, which is reasonable, and by arranging the fourth plane bearing, the frictional resistance in the pressing action of the fourth pressing member 304 can be reduced, and by arranging the fourth thrust plate, the force applied to the front side of the box body 4 can be evenly distributed.

[0049] One end of each of the fifth pressurizing components 305 is mounted on the inner side of the rear mounting portion 205 via a fifth planar bearing (not shown in the figure), and the other end of all the fifth pressurizing components 305 abuts against the lower side of the housing 4 via a common fifth thrust plate. In other words, the fifth pressurizing components 305 are arranged inside the rear mounting portion 205 in a reasonable manner. By providing the fifth planar bearing, the frictional resistance during the pressurizing process of the fifth pressurizing components 305 can be reduced. By providing the fifth thrust plate, the force applied to the front side of the housing 4 can be evenly distributed.

[0050] In some embodiments, in the left-right direction, except for the frame 2 furthest from the first pressure member 301 which is fixed in position, the other frames 2 can move in the left-right direction. For example, Figure 1 As shown, in the left-right direction, the first pressure member 301 is installed on the right-side upright plate 101. The first pressure member 301 is used to apply pressure to the right side of the box body 4, and the left side of the box body 4 abuts against the left-side upright plate 101. The frame 2 furthest from the first pressure member, that is, the leftmost frame 2, is fixed on the mounting base 1, and the remaining frames 2 can move in the left-right direction. By setting the remaining frames 2 to be movable in the left-right direction, on the one hand, the box body 4 has a certain follow-up mechanism in the left-right direction when changing the magnitude of the force applied to the box body 4; on the other hand, before applying pressure to the box body 4, the positions of the force application points on the front and rear sides of the box body 4 can be easily adjusted by moving the remaining frames 2.

[0051] In some embodiments, a sliding assembly 5 is further included. The sliding assembly 5 includes a slide rail 501 and a moving member 502. The slide rail 501 extends left and right and serves as a guide. The number of moving members 502 is the same as the number of the other frames 2. The moving members 502 are correspondingly arranged below the lower mounting portion 203 of the frame 2 and fixed to the corresponding frame 2. The moving members 502 cooperate with the slide rail 501 so that the other frames 2 can move independently in the left and right directions. By cooperating with the slide rail 501, the friction during the movement can be reduced, thereby reducing the resistance to movement, and it also guides the left and right movement of the box 4.

[0052] In some embodiments, each movable component 502 includes a support block 5021 and a roller 5022 disposed on the support block 5021. The support block 5021 supports the frame 2, and the frame 2 is fixed to the support block 5021. The roller 5022 cooperates with the slide rail 501. By cooperating with the slide rail 501, the friction during the movement can be reduced, thereby reducing the resistance to movement, and also guiding the left and right movement of the box 4.

[0053] In some embodiments, the first pressing member 301, the second pressing member 302, the third pressing member 303, the fourth pressing member 304 and the fifth pressing member 305 are all oil cylinders, which are reliable in operation and can stably apply pressure to the box body 4.

[0054] The second aspect of the present application further provides a three-way servo cooperative control system of a model box.

[0055] The three-way servo cooperative control system of the model box according to the second aspect of the present application is used for performing three-way servo cooperative control on the model box 1000 according to any one of the embodiments of the first aspect of the present application. The three-way servo cooperative control system of the model box comprises a control module, an execution module and a detection module.

[0056] Specifically, the control module is used for calculating the required pressure value of each of the first pressing member 301, the required pressure value of each of the second pressing member 302, the required pressure value of each of the third pressing member 303, the required pressure value of each of the fourth pressing member 304 and the required pressure value of each of the fifth pressing member 305 according to the required expected pressure value of different sides of the box body 4, and sending an instruction to the execution module; wherein the required expected pressure value of different sides of the box body 4 can be the same or different, which needs to be input into the control module according to experimental requirements.

[0057] The execution module simultaneously applies pressure to the box body 4 by the first pressing member 301, the second pressing member 302, the third pressing member 303, the fourth pressing member 304 and the fifth pressing member 305 according to the instruction; it can be understood that the sum of the applied pressure of the first pressing member 301, the sum of the applied pressure of the second pressing member 302, the sum of the applied pressure of the third pressing member 303, the sum of the applied pressure of the fourth pressing member 304 and the sum of the applied pressure of the fifth pressing member 305 increase from zero to the expected pressure value of the corresponding side in the process of continuous pressing, and in this process of continuous pressing, the pressing of the first pressing member 301, the pressing of the second pressing member 302, the pressing of the third pressing member 303, the pressing of the fourth pressing member 304 and the pressing of the fifth pressing member 305 are independent of each other and cooperatively work, thereby realizing three-way servo cooperative control of the model box 1000.

[0058] The detection module is used for detecting the stress in the rock and soil in the box body 4 and feeding back to the control module. It can be understood that the detection module can be a stress sensor distributed in the rock and soil of the box body 4. When different sides of the box body 4 are pressurized, the detection module can continuously check the stress change in the rock and soil in real time and feed back to the control module in real time. By reading the detection data through the control module, the stress change can be analyzed to complete the simulation experiment of the rock and soil activity fracture disaster effect.

[0059] The three-way servo cooperative control system of the model box according to the second aspect of the present application has the same technical effects as the model box 1000 according to the first aspect of the present application, and thus the details are not described herein.
