Description

Technical Field

[0001] The invention relates to the technical field of fault dislocation simulation experiments, and in particular to a dislocation angle adjustment structure of a fault dislocation simulation experiment device. Background Art

[0002] With the continuous advancement of major infrastructure construction around the world, especially its expansion into the deep earth, deep sea and central and western regions, the safety issues of cross-fault civil engineering have become increasingly prominent. The destructive impact of fault movement on engineering structures such as tunnels, bridges, and underground facilities has become a key issue that needs to be urgently addressed in the engineering field. In terms of fault movement simulation technology, existing experimental devices and research methods have made certain progress, but there are still many shortcomings. Current research mainly focuses on using vibration tables to simulate fault movement, but this method has limitations in simulating the complexity of fault movement (such as different fault types and angles), and cannot flexibly adjust the fault movement angle, making it difficult to meet diverse experimental needs.

[0003] The existing Chinese patent with publication number CN219626202U includes a frame, an upper plate bottom plate, a lower plate bottom plate, a staggered angle fixing plate, a staggered angle adjustment plate, a driving actuator, a guide sleeve, a staggered angle adjustment pin, a driving angle adjustment pin, a guide sleeve rotating shaft and a guide adjustment pin, wherein the staggered angle fixing plate is connected to the frame and the lower plate bottom plate to support the upper plate bottom plate. The staggered angle adjustment plate can slide on the staggered angle fixing plate.

[0004] When the above device is in use, the guide groove on the adjustment plate allows the offset angle adjustment plate to slide on the circular groove of the offset angle fixing plate, and the convex shaft moves in the guide groove. The offset angle adjustment plate has different angle holes, which are aligned with the positioning holes and then fixed with the offset angle adjustment pins to achieve positioning at different offset angles. However, in actual use, most existing devices can only simulate a single type of fault offset, and it is difficult to achieve flexible switching of multiple fault types (such as normal faults, reverse faults, and strike-slip faults) on the same device, resulting in limited reliability of the experimental results.

[0005] For this purpose, we proposed a fault dislocation angle adjustment structure for the simulation experimental device. Summary of the invention

[0009] Preferably, rectangular plates are fixedly connected to symmetric positions on both sides of the inner wall of the rectangular shell.

And one end of the rectangular shell close to the first test box is penetrated and fixedly connected with a first screw rod driven to rotate by a power mechanism. The first screw rod penetrates into the inner wall of the first sleeve block and is screwed.

[0010] Preferably, the elevating mechanism includes L-shaped rods which are penetrated and connected with the moving plate at symmetric positions on both sides for lifting and lowering movement. The ends of the two L-shaped rods are fixedly connected with a lifting plate for pushing the first test box to move up and down. Z-shaped grooves are provided at symmetric positions on both sides of the two rectangular plates. The bottom end of each L-shaped rod penetrates into the inner wall of the adjacent Z-shaped groove on one side and is movably connected. A support plate is movably connected to the support rod in a lifting manner. A second spring for guiding the first test box to move back is fixedly connected to the opposite surfaces of the support plate and the support rod.

[0011] Preferably, a ratchet wheel is coaxially and fixedly connected to one side of the rectangular housing, and a first torsion spring for guiding the reset rotation of the adjusting rod is fixedly connected to the opposite surface of the ratchet wheel and the rectangular housing. One side of the rectangular housing close to the ratchet wheel is penetrated and rotatably connected with a pawl for locking the ratchet wheel, and a second torsion spring for guiding the pawl to engage with the ratchet wheel is fixedly connected to the opposite surface of the pawl and the rectangular housing.

[0012] Preferably, the adjusting mechanism includes two rotating blocks rotatably connected to the symmetric positions on both sides of the lifting plate. The ends of the two rotating blocks on each side are rotatably connected with a first rack for driving the adjusting rod to rotate and adjust.

Spring pieces for guiding the meshing transmission between the first rack and the transmission gear are fixedly connected to the opposite surfaces of the first rack on each side and the lifting plate.

[0013] Preferably, a translation mechanism for driving the second test chamber to simulate a strike-slip fault is provided on the rectangular housing. The translation mechanism includes a fixed block fixedly connected to one end of the inner wall of the rectangular housing close to the second test chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] First, through the design of the lifting mechanism, the first test chamber can realize stable reciprocating lifting movement under the push of the lifting plate, and can accurately simulate the dislocation process of normal faults and reverse faults. By controlling the moving distance and speed of the lifting plate, accurate control of the dislocation amplitude and rate of the fault can be achieved, meeting the simulation requirements of fault movement under experimental conditions. Moreover, the second spring can push the first test chamber to move back under the action of the support rod, ensuring the continuity of the experimental process, enabling the experimental device to maintain stable performance in multiple experiments, reducing experimental errors caused by human operation or equipment failures, and improving the repeatability and reliability of experimental results.

[0017] Second, through the meshing transmission between the first rack and the transmission gear, along with multiple reciprocating experiments of the experimental device, the adjusting rod can be driven to rotate and adjust at equal angles, enabling the experimental device to flexibly adjust the fault dislocation angle. By precisely controlling the rotation angle of the adjusting rod, it provides broader experimental conditions for studying the influence of fault dislocation at different angles. Moreover, the locking function of the ratchet and pawl can ensure the stability of the adjusting rod after adjustment, avoiding experimental errors caused by angle changes, enabling the experimental device to maintain a stable operating state after angle adjustment, and ensuring the accuracy and reliability of experimental results.

[0018] Third, the second screw drives the second sleeve block to rotate reciprocally, and then through the meshing transmission between the missing gear and the second rack, the horizontal reciprocating movement of the second test box is realized, which can accurately simulate the fault movement process of the translational fault, providing experimental support for studying the influence of the translational fault on engineering structures. By precisely controlling the rotation speed and stroke of the second screw, the accurate control of the fault movement rate and amplitude of the translational fault can be achieved, meeting the simulation requirements of the translational fault movement under experimental conditions. The addition of the translation mechanism enables the experimental device to simultaneously simulate the movements of normal faults, reverse faults, and translational faults, greatly expanding the applicable range of the device, enabling the experimental device to meet the simulation requirements of more types of fault dislocations, and providing more comprehensive experimental support for the research of cross-fault civil engineering.

[0019] By using the above-mentioned structures in combination, the problem that in the actual use process of the existing device, most of the existing devices can only simulate a single type of fault dislocation, it is difficult to flexibly switch between multiple fault types (such as normal faults, reverse faults, translational faults) on the same device, resulting in limited reliability of experimental results, is solved.

[0041] And the first arc-shaped plates 7 and the second arc-shaped plates are made of transparent high-strength plastic plates to ensure the structural stability, so as to facilitate the subsequent observation and photographing of the fault dislocation experiment process.

[0042] Embodiment Three:

[0043] On the basis of Embodiment Two, further:

[0044] Rectangular plates 11 are fixedly connected to symmetric positions on both sides of the inner wall of the rectangular housing 1. A moving plate 12 is horizontally movably connected to the two rectangular plates 11. The bottom of the moving plate 12 is penetrated and fixedly connected with a first sleeve block 13. One end of the rectangular housing 1 close to the first test chamber 3 is penetrated and rotatably connected with a first screw rod 14 driven by a power mechanism to rotate, and the first screw rod 14 penetrates into the inner wall of the first sleeve block 13 and is screwed.

[0045] The lifting mechanism includes L-shaped rods 15 that penetrate through and are connected to move up and down symmetrically on both sides of the moving plate 12. The ends of the two L-shaped rods 15 are fixedly connected to a lifting plate 16 that pushes the first test box 3 to move up and down. Z-shaped grooves 111 are provided at symmetric positions on both sides of the rectangular plates 11. The bottom ends of each side of the L-shaped rods 15 respectively penetrate through and are movably connected to the inner wall of the adjacent Z-shaped groove 111. A support plate 17 is connected to move up and down on the support rod 2. A second spring 18 that guides the first test box 3 to move back is fixedly connected to the opposite surfaces of the support plate 17 and the support rod 2.

[0046] When in use, through the rectangular plate 11 provided on the rectangular housing 1, the rectangular plate 11 is fixedly supported on the inner wall of the rectangular housing 1. And the moving plate 12 provided on the rectangular plate 11 enables the moving plate 12 to be horizontally movably connected on the rectangular plate 11. Through the first screw rod 14 provided on the rectangular housing 1, and the first screw rod 14 is driven to rotate by a motor after being powered on, the motor can drive the first screw rod 14 to perform a fixed-axis reciprocating rotation on the rectangular housing 1. Through the first sleeve block 13 provided on the moving plate 12, and the first screw rod 14 penetrates through the inner wall of the first sleeve block 13 and is screwed, along with the first sleeve block 13 performing a fixed-axis reciprocating rotation, the first sleeve block 13 can drive the moving plate 12 to perform a horizontal reciprocating movement on the rectangular plate 11 under the action of the first screw rod 14.

[0047] Through the L-shaped rods 15 provided on the moving plate 12 and the lifting plate 16 provided on the L-shaped rods 15, the L-shaped rods 15 can drive the lifting plate 16 to be movably connected to move up and down on the moving plate 12. And due to the Z-shaped grooves 111 provided on the rectangular plates 11, the bottom ends of the L-shaped rods 15 can be movably supported on the inner walls of the Z-shaped grooves 111. When the moving plate 12 moves to the extreme position at one end of the support rod 2, the L-shaped rods 15 can push the lifting plate 16 to move in the upward vertical direction under the action of the Z-shaped grooves 111. And the lifting plate 16 is located at the bottom of the support rod 2, so the lifting plate 16 can push the support rod 2 and the first test box 3 to move in the upward vertical direction, realizing the positive and reverse fault dislocation simulation experiment of the overlying soil layer inside the first test box 3.

[0048] Through the support plate 17 provided on the support rod 2, the support plate 17 can be connected to move up and down on the outer contour of the support rod 2. Through the second spring 18 provided on the support plate 17, and under the action of the second spring 18, the support plate 17 can move to abut against the top of the rectangular housing 1, so that the support rod 2 can support the position of the first test chamber 3 under the action of the second spring 18. When the support rod 2 drives the first test chamber 3 to move in the upward vertical direction, the second spring 18 can be squeezed and contracted under the action of the support rod 2. When the moving plate 12 moves in the reset direction away from the support rod 2, the L-shaped rod 15 can pull the lifting plate 16 to move in the downward vertical direction for reset under the action of the Z-shaped groove 111. At this time, the lifting plate 16 releases the force that pushes the support rod 2 upward, so that the support plate 17 can push the support rod 2 and the first test chamber 3 to move in the downward vertical direction for reset under the action of the elastic force.

[0049] During the process of the support rod 2 driving the first test chamber 3 to move up and down reciprocally, the first test chamber 3 can drive the support rod 2 to move horizontally along the inner wall of the support groove 101 according to the inclination angle of the adjusting rod 6, avoiding hindering the simulation of the normal and reverse fault dislocations of the first test chamber 3.

[0050] Embodiment 4:

[0051] On the basis of Embodiment 3, further:

[0052] On one side of the rectangular housing 1, a ratchet wheel 19 is coaxially fixed to the adjusting rod 6. A first torsion spring 20 for guiding the reset rotation of the adjusting rod 6 is fixedly connected to the opposite surface of the ratchet wheel 19 and the rectangular housing 1. One side of the rectangular housing 1 close to the ratchet wheel 19 is penetrated and rotatably connected to a pawl 21 for locking the ratchet wheel 19. A second torsion spring 22 for guiding the pawl 21 to engage with the ratchet wheel 19 is fixedly connected to the opposite surface of the pawl 21 and the rectangular housing 1.

[0053] The adjusting mechanism includes two rotating blocks 23 rotatably connected to the symmetric positions on both sides of the lifting plate 16. At the end of each of the two rotating blocks 23 on each side, a first rack 24 for driving the rotation adjustment of the adjusting rod 6 is rotatably connected. Transmission gears 25 adapted to the teeth of the first rack 24 are coaxially fixed to the symmetric positions of the two adjusting rods 6 on both sides. On the opposite surface of each first rack 24 and the lifting plate 16, a spring piece 26 for guiding the meshing transmission of the first rack 24 and the transmission gear 25 is fixedly connected.

[0054] During use, through the ratchet wheel 19 provided on the adjusting rod 6, and the ratchet wheel 19 can be fixedly connected coaxially with the adjusting rod 6, the adjusting rod 6 can drive the ratchet wheel 19 to rotate and connect synchronously on the rectangular housing 1. And the first torsion spring 20 provided on the ratchet wheel 19 is convenient for the subsequent first torsion spring 20 to drive the ratchet wheel 19 and the adjusting rod 6 to rotate for reset. Through the pawl 21 provided on the rectangular housing 1, the pawl 21 is rotatably supported on the rectangular housing 1, and the second torsion spring 22 provided on the pawl 21 enables the pawl 21 to be engaged with the tooth grooves on the ratchet wheel 19 under the action of the second torsion spring 22. Then the pawl 21 can lock the ratchet wheel 19 to ensure the stability of the ratchet wheel 19 and the adjusting rod 6 and prevent the first torsion spring 20 from driving the ratchet wheel 19 to rotate for reset.

[0055] Through the rotating block 23 provided on the lifting plate 16, and the first rack 24 provided on the rotating block 23, the rotating block 23 can rotatably support the first rack 24 on the lifting plate 16. Through the transmission gear 25 provided on the adjusting rod 6, the transmission gear 25 can be fixedly connected coaxially with the adjusting rod 6. Through the spring piece 26 provided on the first rack 24, the first rack 24 can be engaged with the teeth on the transmission gear 25 under the push of the spring piece 26. When the moving plate 12 drives the lifting plate 16 to move horizontally towards the direction close to the support rod 2, the transmission gear 25 can drive the adjusting rod 6 to rotate towards the direction close to the second test box 5 under the action of the first rack 24. And the adjusting rod 6 can drive the first arc plate 7 and the second arc plate 8 to synchronously perform arc movement adjustment along the inner wall of the arc groove 351. At the same time, the adjusting rod 6 can drive the ratchet wheel 19 to rotate synchronously, so that the first torsion spring 20 rotates and contracts under the action of the ratchet wheel 19. When the first rack 24 moves out of contact with the transmission gear 25, then the pawl 21 locks the ratchet wheel 19 under the action of the second torsion spring 22 to ensure the stability of the adjusting rod 6 and prevent the first torsion spring 20 from driving the ratchet wheel 19 to rotate for reset. When the moving plate 12 drives the lifting plate 16 to horizontally reset towards the direction away from the support rod 2, and the first rack 24 abuts against the transmission gear 25, at this time the pawl 21 locks the ratchet wheel 19, so that the rotating block 23 rotates under the action of the transmission gear 25 and drives the first rack 24 to move downward and out of contact with the transmission gear 25.

[0056] By the combined use of the above structures, such as Figure 1 and Figure 2As shown, the initial angle of the adjusting rod 6 is inclined to one side of the first test chamber 3. Along with the horizontal reciprocating movement of the lifting plate 16 driven by the moving plate 12, the first rack 24 can drive the adjusting rod 6 to rotate and adjust at equal angles in the direction close to the second test chamber 5 through the transmission gear 25, further realizing the simulation of the fault dislocation test at different angles in the first test chamber 3. When the adjusting rod 6 is inclined to one side of the first test chamber 3, the first test chamber 3 conducts a normal fault dislocation experiment at this time. When the adjusting rod 6 is inclined to one side of the second test chamber 5, the first test chamber 3 conducts a reverse fault dislocation experiment.

[0057] Along with the adjusting rod 6 rotating to the limit position close to one side of the second test chamber 5, the first test chamber 3 completes a round of simulation experiments of normal and reverse faults. At this time, the end of the pawl 21 is manually toggled by personnel to be disengaged from the ratchet wheel 19, so that the first torsion spring 20 can drive the adjusting rod 6 to rotate and reset in the direction close to one side of the first test chamber 3 through the ratchet wheel 19.

[0061] A missing gear 29 for driving the second test chamber 5 to move horizontally reciprocally is fixedly connected to the outer contour of one end of the second sleeve block 28 close to the moving rod 4.

When the moving plate 12 moves to the extreme position away from one end of the support rod 2, and the second screw rod 31 moves to the inner wall of the second sleeve block 28, the second sleeve block 28 can rotate forward on the fixing block 27 under the action of the second screw rod 31. When the moving plate 12 moves back towards the end close to the support rod 2, the second sleeve block 28 rotates reversely under the action of the second screw rod 31, realizing the fixed-axis reciprocating rotation of the second sleeve block 28 on the fixing block 27. Through the missing gear 29 provided on the second sleeve block 28, the second sleeve block 28 can synchronously drive the missing gear 29 to reciprocate. Through the second rack 30 provided on the moving rod 4, and the second rack 30 is adapted to the teeth on the missing gear 29. Along with the reciprocating rotation of the missing gear 29, the second rack 30 can drive the second test box 5 to horizontally reciprocate along the inner wall of the moving groove 102 through the moving rod 4, realizing that the second test box 5 can drive the overlying soil layer inside to simulate the translational fault dislocation test.
