For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following describes a large model box specimen automatic transportation system 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0029] like Figure 1-Figure 4 As shown, the large model box specimen automated transport system 1 according to an embodiment of the present invention includes a base, a specimen, a specimen box 10, a guide rail 20, a steering device 30, a front force application device 40, a rear baffle 50, a roller conveyor device 60 and a gantry force application assembly 70 (the up and down, left and right and front and back directions are shown by the arrows in the figure).

[0030] The sample is solidified by the test ratio material. It should be understood that the test ratio material is a material that is a mixture of simulated rock components and a curing agent for the test. The technicians in this field can adjust its composition and proportion according to actual needs. The sample needs to be solidified during the test.

[0031] The sample box 10 is wrapped around the sample. Specifically, the sample box 10 can be partially removed during the test to facilitate observation of the sample.

[0032] The guide rail 20 is provided on the base and is oriented in the front-rear direction.

[0033] The steering device 30 includes a steering base 31, a turntable 32 and a plurality of steering rollers 33. The plurality of steering rollers 33 are rollably disposed on the turntable 32 and are spaced apart and parallel to each other. The turntable 32 is rotatably disposed on the steering base 31 between a vertical position and a parallel position. When the turntable 32 is in the vertical position, the axial directions of the plurality of steering rollers 33 are oriented in the front-rear direction. When the turntable 32 is in the parallel position, the axial directions of the plurality of steering rollers 33 are oriented in the left-right direction. The steering base 31 is slidably disposed on the guide rail 20 between the docking position and the test position. Specifically, Figure 1 , Figure 2 and Figure 4 The middle turntable 32 is located in the vertical position. Figure 3 The middle turntable 32 is located at the parallel position.

[0034] The front force applying device 40 is disposed at the front end of the guide rail 20. When the steering base 31 is located at the test position and the turntable 32 is located at the parallel position, the front force applying device 40 is adapted to abut against the front end surface of the sample box 10 on the steering device 30 and to apply force toward the sample box 10. Specifically, the front force applying device 40 may include a force applying plate 41 and a front hydraulic cylinder 42, and the front hydraulic cylinder 42 is adapted to drive the force applying plate 41 backward.

[0035] The rear baffle 50 is disposed at the rear end of the guide rail 20 . When the steering base 31 is located at the test position and the turntable 32 is located at the parallel position, the rear end surface of the sample box 10 on the steering device abuts against the rear baffle 50 .

[0036] In other words, when the turning base 31 is located at the test position and the turntable 32 is located at the parallel position, the sample box 10 is suitable for being clamped between the force applying plate 41 and the rear baffle 50 .

[0037] The roller conveyor device 60 is arranged on the base, and the roller conveyor device 60 includes a conveyor frame 61 and a plurality of conveyor rollers 62. The plurality of conveyor rollers 62 are rotatably arranged on the conveyor frame 61. The axial directions of the plurality of conveyor rollers 62 are all oriented along the front-to-back direction and the plurality of conveyor rollers 62 are arranged in parallel and spaced apart along the left-to-right direction. When the steering base 31 is located at the docking position and the turntable 32 is located at the vertical position, the roller conveyor device 60 is suitable for conveying the sample box 10 to the steering roller 33 of the steering device 30.

[0038] Each gantry force-applying assembly 70 includes a rectangular frame 71 and a plurality of gantry force-applying devices 72. The rectangular frame 71 is slidably disposed on the guide rail 20 between the avoidance position and the force-applying position. The plurality of gantry force-applying devices 72 are disposed on the four sides of the rectangular frame 71. The rectangular frame 71 is suitable for avoiding the sample box 10 when in the avoidance position. When the rectangular frame 71 is in the force-applying position, the steering base 31 is in the test position, and the turntable 32 is in the parallel position, the plurality of gantry force-applying devices 72 are suitable for abutting against the sample box 10 and for applying force toward the sample box 10. Specifically, the gantry force-applying device 72 may include a gantry hydraulic cylinder and a force-applying seat, and a roller is disposed on the force-applying seat. Four gantry force-applying devices 72 are disposed on each rectangular frame 71 and are respectively disposed on the upper, lower, left, and right sides of the rectangular frame 71. The four gantry force-applying devices 72 are suitable for abutting against the upper, lower, left, and right four surfaces of the sample box 10 one by one to apply force in the four directions of upper, lower, left, and right.

[0039] It can be understood by those skilled in the art that the sliding of the steering base 31, the rotation of the turntable 32, the rolling of the steering roller 33, and the rolling of the conveying roller 62 are all provided with corresponding driving devices, and those skilled in the art can select the type of driving device according to actual needs.

[0040] Reference below Figure 1-Figure 4 The working process of the large model box specimen automatic transportation system 1 according to the embodiment of the present invention is described.

[0041] The sample box 10 and the sample inside are moved onto the conveying roller 62 of the roller conveying device 60. The turning base 31 is located at the docking position, the turntable 32 is located at the vertical position, and the rectangular frame 71 is located at the avoidance position.

[0042] The sample box 10 is conveyed to the left to the steering roller 33 of the steering device 30 by the rolling of the conveying roller 62. The steering roller 33 rolls to adjust the position of the sample box 10 to keep the sample box 10 balanced. At this time, the length direction of the sample is oriented in the left-right direction.

[0043] The steering base 31 moves to the test position, and the turntable 32 rotates to the parallel position, so that the sample is rotated to be oriented along the front-to-back direction in the length direction.

[0044] When the turning base 31 reaches the test position, the rear surface of the sample box 10 abuts against the rear baffle 50 .

[0045] The rectangular frame 71 moves to the force application position, so that the gantry force application device 72 abuts against the sample box 10, and the front force application device 40 abuts against the front surface of the sample box 10, completing the transportation of the sample and preparing for the test.

[0046] During the test, the front force applying device 40 and the plurality of gantry force applying devices 72 apply force to the specimen in different directions to simulate the force conditions required for the test.

[0047] For example, force can be applied to the specimen in the left-right and front-back directions until it reaches a balanced state to simulate the natural stress field, and the stress and displacement state at this moment can be detected and recorded using a detection device. Then, force can be applied in the left-right and top-bottom directions to simulate the thrust and slip movement of the fault. When the displacement reaches the critical value, the stress state is recorded to obtain the required data.

[0048] The movement of the rectangular frame 71 on the guide rail 20 can simulate different force application positions, thereby improving the applicability of the test.

[0049] According to the large-scale model box sample automatic transportation system 1 of the embodiment of the present invention, by setting up a roller conveying device 60, the roller conveying device 60 can be used to transport the sample box 10 to the steering device 30. By setting up the steering device 30, the steering device 30 can be used to rotate the sample to the direction required for the test, and the sliding of the steering base 31 on the guide rail 20 can move the sample to the required position for the test. Compared with the method of manual handling and simple transportation devices used in the related art, it can realize the automatic transportation of samples, reduce labor intensity, save manpower, and improve transportation efficiency. In addition, the roller conveying method and the rotation of the turntable 32 to adjust the direction of the sample can make the transportation process stable, will not cause disturbance or damage to the sample, and ensure the accuracy of the test results. Moreover, no professional operating qualifications are required, and the test personnel can also complete it by themselves to avoid affecting the test process.

[0050] Therefore, the large model box sample automatic transportation system 1 according to the embodiment of the present invention has the advantages of saving manpower, high transportation efficiency, stable transportation, etc.

[0051] The following describes a large model box specimen automatic transportation system 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0052] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the large model box sample automatic transportation system 1 according to an embodiment of the present invention includes a base, a sample, a sample box 10, a guide rail 20, a steering device 30, a front force device 40, a rear baffle 50, a roller conveyor 60 and a gantry force assembly 70.

[0053] Advantageously, if Figure 1-Figure 3 As shown, at least one of the front and rear edges of the roller conveyor 60 is provided with a guide frame 63 that is higher than the conveying roller 62 and oriented in the left-right direction. In this way, the guide frame 63 can be used to guide the transportation of the sample box 10, further improving the stability of the sample box 10 during transportation.

[0054] Specifically, the guide frame 63 has guide rollers, which are suitable for contacting the sample box 10 on the roller conveyor 60. In this way, the guide rollers can be used to form rolling friction between the guide frame 63 and the sample box 10, thereby reducing the resistance during transportation of the sample box 10, further reducing the disturbance to the sample box 10, and further improving the stability of the sample box 10 during transportation.

[0055] More advantageously, if Figure 1-Figure 4 As shown, at least one of the two edges of the turntable 32 perpendicular to the axial direction of the steering roller 33 is provided with a positioning frame 34 higher than the steering roller 33, and the length direction of the positioning frame 34 is oriented in the horizontal direction and perpendicular to the axial direction of the steering roller 33. In this way, the positioning frame 34 can be used to position the sample box 10 on the steering roller 33, and the stability of the sample box 10 can be improved when the turntable 32 rotates, and the relative movement of the sample box 10 with the steering roller 33 in the axial direction of the steering roller 33 can be avoided, thereby improving the stability of the sample box 10 when turning, and reducing the disturbance of the sample box 10 when turning.

[0056] Furthermore, if Figure 4 As shown, the positioning frame 34 is provided with positioning wheels 35, which are suitable for abutting against the sample box 10 on the steering device 30. In this way, the positioning wheels 35 can be used to form rolling friction between the positioning frame 34 and the sample box 10, thereby reducing the resistance during transportation of the sample box 10, further reducing the disturbance to the sample box 10, and further improving the stability of the sample box 10 during transportation.

[0057] Figure 1-Figure 3 The following is a diagram showing an automated transportation system 1 for large model box specimens according to some examples of the present invention. Figure 1-Figure 3As shown, the large-scale model box sample automatic transportation system 1 also includes a docking frame 80, on which a plurality of docking rollers 81 are arranged, and the axial directions of the plurality of docking rollers 81 are all oriented in the front-rear direction. The docking frame 80 is flippably arranged at the left end of the conveying frame 61 between the extended position and the retracted position. When the docking frame 80 is in the extended position, the docking roller 81 and the conveying roller 62 are located in the same plane, and when the docking frame 80 is in the retracted position, the docking frame 80 extends downward from the conveying frame 61. Specifically, when the steering base 31 is in the docking position, the turntable 32 is in the vertical position, and the docking frame 80 is in the extended position, the steering roller 33, the docking roller 81, and the conveying roller 62 are parallel and located in the same plane. In this way, the sample box 10 can be smoothly transported from the roller conveyor device 60 to the steering device 30 through the docking rollers 81, so as to further improve the transportation stability and avoid disturbance of the transportation of the sample box 10 due to lack of support between the roller conveyor device 60 and the steering device 30. Moreover, after being transported to the steering device 30, the docking frame 80 can be flipped to the retracted position to avoid the rotation of the sample box 10, so as to avoid interference with the rotation of the sample box 10.

[0058] It is understandable to those skilled in the art that the flipping of the docking frame 80 and the rotation of the docking roller 81 are also provided with corresponding driving devices, and those skilled in the art can select the type of driving device according to actual needs.

[0059] Specifically, Figure 3 As shown, both ends of the sample box 10 in the length direction are provided with plane bearings 11. In this way, the plane bearings 11 can be used to eliminate the influence of the component forces in directions other than the length direction of the sample box 10 when the end force of the sample box 10 is applied. For example, when the front force applying device 40 applies force to the sample box 10 backward, the influence of the component forces in the up, down, left, and right directions on the force applied in the front and rear directions can be avoided, ensuring that the force in the front and rear directions acts on the sample reliably and accurately, thereby ensuring the accuracy and reliability of the test results.

[0060] Alternatively, if Figure 3 As shown, each end face of the sample is connected to the plane bearing 11 through a plurality of fasteners arranged in an array. In this way, the plane bearing 11 can be stably and reliably connected to the sample, avoiding relative movement between the plane bearing 11 and the sample to affect the test results.

[0061] More specifically, Figure 1-Figure 3As shown, the large-scale model box sample automatic transport system 1 also includes a front support plate 91 and a rear support plate 92, the front support plate 91 is arranged at the front end of the guide rail 20, the front force applying device 40 is arranged on the front support plate 91, the rear support plate 92 is arranged at the rear end of the guide rail 20, the rear baffle 50 is formed on the rear support plate 92, and a connecting rod 93 is connected between the front support plate 91 and the rear support plate 92. Specifically, the connecting rod 93 can be multiple and arranged at intervals. In this way, the overall rigidity and stability of the large-scale model box sample automatic transport system 1 can be improved, and local deformation can be avoided to affect the test results.

[0062] In some embodiments, the sample is provided with a preset fracture zone, which divides the sample into a plurality of sub-segments arranged along the length direction, and there are a plurality of gantry force-applying assemblies 70 which are arranged at intervals along the front-back direction, and when the rectangular frame 71 is at the force-applying position, the steering base 31 is at the test position, and the turntable 32 is at the parallel position, the plurality of gantry force-applying assemblies 70 are respectively suitable for applying force to different sub-segments. Specifically, there are two preset fracture zones which divide the sample into three sub-segments, and there are two gantry force-applying assemblies 70. In this way, the simulation of composite fracture activities under different fracture zones, different force-applying positions, and different force-applying directions can be simulated for multiple sub-segments.

[0063] For example, when it is necessary to simulate strike-slip motion, after the initial stress field is balanced, force is continued to be applied to the left or right to move one of the sub-segments of the sample in the left-right direction, thereby simulating the strike-slip motion of the fault.

[0064] When thrust movement needs to be simulated, after the initial stress field is balanced, one of the sub-segments of the sample is moved in the up-down direction by continuing to apply force upward or downward, thereby realizing fault thrust movement.

[0065] When it is necessary to simulate the strike-slip and thrust movement of the fault at the same time, after the initial stress field is balanced, one of the sub-segments of the sample can be displaced in the left-right and up-down directions by applying force upward or downward and left or right, thereby realizing the strike-slip and thrust movement of the fault.

[0066] Reference below Figure 1-Figure 4 The working process of the large model box specimen automatic transportation system 1 according to the embodiment of the present invention is described.

[0067] The sample box 10 and the sample inside are moved onto the conveying roller 62 of the roller conveying device 60. The turning base 31 is located at the docking position, the turntable 32 is located at the vertical position, the rectangular frame 71 is located at the avoidance position, and the docking frame 80 is located at the extended position.

[0068] The sample box 10 is transported to the left by the rolling of the conveying roller 62, and after passing through the docking roller 81 of the docking frame 80, it is transported to the steering roller 33 of the steering device 30. The steering roller 33 rolls to adjust the position of the sample box 10 to maintain the balance of the sample box 10. At this time, the length direction of the sample is oriented in the left-right direction, and the docking frame 80 flips to the retracted position.

[0069] The steering base 31 moves to the test position, and the turntable 32 rotates to the parallel position, so that the sample is rotated to be oriented along the front-to-back direction in the length direction.

[0070] When the turning base 31 reaches the test position, the rear surface of the sample box 10 abuts against the rear baffle 50 .

[0071] The rectangular frame 71 moves to the force application position, so that the gantry force application device 72 abuts against the sample box 10, and the front force application device 40 abuts against the front surface of the sample box 10, completing the transportation of the sample and preparing for the test.

[0072] During the test, the front force applying device 40 and the plurality of gantry force applying devices 72 apply force to the specimen in different directions to simulate the force conditions required for the test.

[0073] For example, force can be applied to the specimen in the left-right and front-back directions until it reaches a balanced state to simulate the natural stress field, and the stress and displacement state at this moment can be detected and recorded using a detection device. Then, force can be applied in the left-right and top-bottom directions to simulate the thrust and slip movement of the fault. When the displacement reaches the critical value, the stress state is recorded to obtain the required data.

[0074] The movement of the rectangular frame 71 on the guide rail 20 can simulate different force application positions, thereby improving the applicability of the test.

[0075] Therefore, according to the large-scale model box sample automatic transportation system 1 of the embodiment of the present invention, an automatic mechanical structure is adopted, starting from the sample being placed in the roller conveyor 60, the roller conveyor 60 and the steering device 30 are docked by the docking frame 80, the docking frame 80 is retracted, and the steering device 30 is rotated 90 degrees, until the sample is finally stably moved into the test station, the sample can be transported to the test station without disturbance throughout the whole process, and the stability and reliability of the sample on the transportation path can be ensured. At the same time, the use of structures such as the positioning frame 34, the positioning wheel 35, the guide frame 63 and the guide roller effectively reduces the disturbance to the sample and the friction resistance during transportation, and further protects the integrity of the sample.

[0076] Other structures and operations of the large-scale model box specimen automatic transportation system 1 according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described in detail here.
