Description

Technical Field

[0001] The present invention belongs to the technical field of dynamic vibration testing, and specifically refers to a building structure simulation testing device based on BIM technology. Background Art

[0002] Buildings generally have earthquake-resistant requirements in their structural design. The vibration test platform is a device specifically used for dynamic testing of such components. If they are small structures used for connection, they can be directly installed on the test platform for testing. If they are the main structure of the building, it is generally necessary to make a proportional model to simulate and calculate the test results.

[0003] Since the vibrations that buildings actually face are mostly natural disasters, including typhoons, earthquakes, floods and tsunamis, the impact vibrations are mostly disordered and non-periodic; however, the vibrations simulated by current vibration test platforms are mostly periodic vibrations. This type of test platform is actually more suitable for vibration testing of structural components on mechanical equipment.

[0004] The current solution is to set random parameters in the software to break the original periodic pattern. This is not only costly, but also because the axial movements of the vibration test platform are mutually restricted, even if the extension and retraction of the axes can cooperate with each other in the software, once there are small problems in the hardware such as response jams and lost pulse signals, it is possible to cause the entire device to get stuck. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a building structure simulation test device based on BIM technology, which can drive the top disc to perform non-periodic continuous swing and oscillation through a unidirectional stable rotating motor; the present invention uses multiple groups of asynchronous driving gears and asynchronous driven gears with different transmission ratios to enable the driving sleeve to drive multiple hollow sleeve rods arranged in a ring to rotate at different speeds, thereby allowing each group of non-periodic vibration drive components and anti-stuck telescopic control mechanisms to reciprocate and telescopically slide in different cycle periods, ultimately achieving non-periodic swing control of the top disc.

[0006] Moreover, since the top disc may stop at any unknown angle after the test is completed, the present invention also creatively proposes a synchronous reset and leveling mechanism, which synchronously unlocks the rotation of the crankshaft body by pressing down the crankshaft body with the crankshaft fork, and then through the slope coordination between the lifting ramp sleeve and the rotating ramp sleeve, the unlocked crankshaft body can automatically rotate and reset, thereby achieving the leveling and reset of the top disc.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a building structure simulation test device based on BIM technology, including a main driving mechanism, a synchronous reset and leveling mechanism, a non-periodic vibration driving component and an anti-stuck telescopic control mechanism, the main driving mechanism includes a main base plate, a main driving component and an asynchronous transmission component, the main driving component is arranged on the main base plate, and the asynchronous transmission component is rotatably arranged on the main driving component.

[0008] Through the transmission of the asynchronous transmission component, when the main drive component continues to rotate stably, each group of non-periodic vibration drive components can be driven to produce asynchronous reciprocating expansion and contraction. Since the reciprocating expansion and contraction periods of each group of non-periodic vibration drive components are different, the shaking and vibration of the top disc will also be non-periodic.

[0009] Preferably, the main drive assembly includes a transmission disc, a drive motor and a drive sleeve, the transmission disc is arranged on the main base plate, the transmission disc is provided with a disc circular hole portion and a disc guide rod in an annular shape, the drive motor is arranged on the main base plate, the drive sleeve is fixedly connected to the output shaft of the drive motor, and the drive sleeve is rotatably arranged at the center position of the transmission disc.

[0010] As a further preferred embodiment of the present invention, the asynchronous transmission assembly includes an asynchronous driving gear, an asynchronous driven gear and a hollow sleeve rod, the hollow sleeve rod is rotatably arranged in the circular hole portion of the disc, the asynchronous driving gear and the asynchronous driven gear are arranged in groups, the transmission ratios of each group of asynchronous driving gear and asynchronous driven gear are different, and a polygonal through hole is provided in the center of the hollow sleeve rod.

[0011] By designing different transmission ratios of each set of asynchronous driving gears and asynchronous driven gears, each set of non-periodic vibration driving components can reciprocate and extend with their own different periods. In this case, the top disc will exhibit non-periodic swing vibrations, thereby simulating the vibrations experienced by the house, thereby achieving the technical effect of dynamically testing building models or small components on the vibration disc.

[0012] Furthermore, the synchronous reset and leveling mechanism includes a crankshaft assembly and a crankshaft reset assembly, the crankshaft assembly is slidably arranged in the asynchronous transmission assembly, and the crankshaft reset assembly is sleeved on the outside of the crankshaft assembly.

[0013] At the end of the vibration test, the telescopic ranges of each group of hydraulic telescopic components are not the same; therefore, by shifting the crankshaft fork and utilizing the lifting ramp sleeve that can only be lifted and lowered but not rotated to calibrate the original angle of the rotating ramp sleeve, the crankshaft body after the rotation restriction is released can be automatically rotated to an angle matching the lifting ramp sleeve under the cooperation of the inclined surfaces of the lifting ramp sleeve and the rotating ramp sleeve, thereby achieving the resetting of the non-periodic vibration drive assembly and the anti-jamming telescopic control mechanism.

[0014] Preferably, the crankshaft assembly includes a crankshaft body and a crankshaft fork, an eccentric rod is provided in the middle position of the crankshaft body, and a top round rod and a bottom round rod are respectively provided at both ends of the crankshaft body, and a top polygonal rod matching the polygonal through hole is provided at the bottom of the top round rod, the top round rod is snap-fitted and slidably arranged in the main base plate, the top polygonal rod is snap-fitted and slidably arranged in the polygonal through hole, and a slope portion is provided on the top of the top polygonal rod for facilitating entry into the polygonal through hole, the top round rod is rotatably arranged in the polygonal through hole, the crankshaft fork is snap-fitted and slidably arranged on the disc guide rod, and the crankshaft fork is located above the crankshaft reset assembly.

[0015] By pressing the crankshaft fork, each group of crankshaft bodies can be pressed down as a whole, so that the top polygonal rod is disengaged from the polygonal through hole. At this time, the top round rod rotates in the polygonal through hole, and the crankshaft body is in a state of free rotation. At this time, the rotating ramp sleeve is limited by the lifting ramp sleeve. No matter what angle the rotating ramp sleeve is at before adjustment, it can be automatically reset, thereby realizing the reset of the non-periodic vibration drive component and the anti-stuck telescopic control mechanism.

[0016] As a further preferred embodiment of the present invention, the crankshaft reset assembly includes a lifting ramp sleeve, a rotating ramp sleeve and a top support spring. The rotating ramp sleeve is fixedly connected to the bottom round rod. The lifting ramp sleeve is evenly distributed in an annular manner with bottom lifting guide rods. The lifting ramp sleeve is slidably engaged with the main bottom plate through the bottom lifting guide rods. The top support spring is arranged between the lifting ramp sleeve and the main bottom plate. The lifting ramp sleeve and the rotating ramp sleeve are designed with chamfered surfaces for matching.

[0017] Through the elastic expansion and contraction of the supporting spring, the lifting ramp sleeve can be allowed to be lifted and lowered to avoid blocking the rotation of the rotating ramp sleeve; and the lifting ramp sleeve and the rotating ramp sleeve can be kept close to and pressed against each other at all times, thereby realizing the rotational reset of the rotating ramp sleeve through the sliding cooperation of the inclined surface.

[0018] Furthermore, the non-periodic vibration drive assembly includes a hydraulic cylinder seat, a driving piston, a reinforced ball socket, a transmission connecting rod and a hydraulic cylinder body. The hydraulic cylinder seat is fixedly connected to the main base plate, the hydraulic cylinder body is snap-fitted in the hydraulic cylinder seat, the driving piston is snap-fitted and slidably arranged in the hydraulic cylinder body, the reinforced ball socket is arranged on the driving piston, and the two ends of the transmission connecting rod are respectively provided with a connecting rod annular portion and a connecting rod ball head portion, the connecting rod ball head portion is rotatably arranged in the reinforced ball socket, the connecting rod annular portion is rotatably arranged on the eccentric rod, and the interior of the connecting rod annular portion is provided with an arc inner wall.

[0019] The thickness of the transmission connecting rod is smaller than the interlayer space where the eccentric rod is located. Combined with the design of the arc inner wall, the crankshaft body can still maintain connection with the driving piston during the lifting process.

[0020] Furthermore, the anti-stuck telescopic control mechanism includes a ball joint, a hydraulic telescopic assembly and an elastic telescopic assembly, the ball joint consists of a ball head and a ball socket, the hydraulic telescopic assembly is arranged on the ball joint, and the elastic telescopic assembly is arranged on the hydraulic telescopic assembly.

[0021] On the one hand, the anti-stuck telescopic control mechanism can affect the angle of the top disc by the extension and retraction of the hydraulic telescopic components. Through the extension and retraction of each group of hydraulic telescopic components, the top disc can be made to vibrate non-periodically. On the other hand, through the extension and retraction of the elastic telescopic sleeve, it can ensure that the top disc will not get stuck during the extension and retraction of each group of hydraulic telescopic components.

[0022] Preferably, the hydraulic telescopic assembly includes a telescopic cylinder, a telescopic push rod and a hydraulic pipeline, the ball joint is arranged between the telescopic cylinder and the hydraulic cylinder seat, the telescopic push rod is slidably arranged in the telescopic cylinder, the telescopic push rod is provided with a flange, and the hydraulic pipeline is arranged between the telescopic cylinder and the hydraulic cylinder body.

[0023] As a further preferred embodiment of the present invention, the elastic telescopic assembly includes an elastic telescopic sleeve, a support spring, an adjusting slider and a top disc. The elastic telescopic sleeve is slidably arranged at the end of the telescopic push rod, the support spring is arranged between the elastic telescopic sleeve and the flange portion, the ball hinge is arranged between the elastic telescopic sleeve and the adjusting slider, the adjusting slider is arranged in the top disc, and the adjusting slider can slide and lock on the top disc.

[0024] By adjusting the position of the adjusting slider on the top disc, the weight of the influence of the hydraulic telescopic assembly on the swing of the top disc when it is extended and retracted can be changed, and the maximum swing amplitude of the top disc can be adjusted and set. By changing the rotation speed of the driving motor, the swing speed can be adjusted and set. By flexibly setting the swing speed and amplitude, different inspection conditions can be simulated and tested.

[0025] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Through the transmission of the asynchronous transmission component, when the main drive component rotates continuously and stably, each group of non-periodic vibration drive components can be driven to produce asynchronous reciprocating expansion and contraction. Since the reciprocating expansion and contraction periods of each group of non-periodic vibration drive components are different, the shaking and vibration of the top disc will also be non-periodic.

[0026] (2) By designing different transmission ratios of each set of asynchronous driving gears and asynchronous driven gears, each set of non-periodic vibration driving components can reciprocate and extend at different periods. In this case, the top disk will exhibit non-periodic swing vibrations, thereby simulating the vibrations of the house, thereby achieving the technical effect of dynamically testing building models or small components on the vibration disk.

[0027] (3) At the end of the vibration test, the telescopic ranges of each group of hydraulic telescopic components are not the same; therefore, by moving the crankshaft fork and using the lifting ramp sleeve that can only be lifted but not rotated to calibrate the original angle of the rotating ramp sleeve, the crankshaft body after the rotation restriction is released can automatically rotate to an angle matching the lifting ramp sleeve under the cooperation of the inclined surfaces of the lifting ramp sleeve and the rotating ramp sleeve, thereby realizing the resetting of the non-periodic vibration drive component and the anti-jamming telescopic control mechanism.

[0028] (4) By pressing the crankshaft fork, each group of crankshaft bodies can be pressed down as a whole, so that the top polygonal rod is disengaged from the polygonal through hole. At this time, the top round rod rotates in the polygonal through hole, and the crankshaft body is in a state where it can rotate freely. At this time, the lifting ramp sleeve limits the rotating ramp sleeve. No matter what angle the rotating ramp sleeve is at before adjustment, it can be automatically reset, thereby realizing the reset of the non-periodic vibration drive component and the anti-jamming telescopic control mechanism.

[0029] (5) Through the elastic expansion and contraction of the supporting spring, the lifting ramp sleeve can be lifted and lowered to avoid blocking the rotation of the rotating ramp sleeve; and the lifting ramp sleeve and the rotating ramp sleeve can be kept close to each other at all times, so that the rotating ramp sleeve can be rotated and reset through the sliding cooperation of the inclined surface.

[0030] (6) The thickness of the transmission connecting rod is smaller than the interlayer space where the eccentric rod is located. Combined with the design of the arc inner wall, the crankshaft body can still maintain connection with the driving piston during the lifting process.

[0031] (7) The anti-stuck telescopic control mechanism can affect the angle of the top disc by the extension and retraction of the hydraulic telescopic components. By the extension and retraction of each group of hydraulic telescopic components, the top disc can be made to vibrate non-periodically. On the other hand, by the extension and retraction of the elastic telescopic sleeve, it can ensure that the top disc will not get stuck during the extension and retraction of each group of hydraulic telescopic components.

[0032] (8) By adjusting the position of the adjusting slider on the top disc, the weight of the influence of the hydraulic telescopic assembly on the swing of the top disc during extension and retraction can be changed, and the maximum swing amplitude of the top disc can be adjusted and set. By changing the rotation speed of the driving motor, the swing speed can be adjusted and set. By flexibly setting the swing speed and amplitude, different inspection conditions can be simulated and tested. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] like Figure 1 to Figure 13As shown, the present invention proposes a building structure simulation test device based on BIM technology, including a main driving mechanism 1, a synchronous reset and leveling mechanism 2, a non-periodic vibration driving component 3 and an anti-stuck telescopic control mechanism 4, the main driving mechanism 1 includes a main base plate 5, a main driving component 6 and an asynchronous transmission component 7, the main driving component 6 is arranged on the main base plate 5, and the asynchronous transmission component 7 is rotatably arranged on the main driving component 6.

[0039] Through the transmission of the asynchronous transmission component 7, when the main drive component 6 rotates continuously and stably, each group of non-periodic vibration drive components 3 can be driven to produce asynchronous reciprocating expansion and contraction. Since the reciprocating expansion and contraction periods of each group of non-periodic vibration drive components 3 are different, the shaking and vibration of the top disc 44 will also be non-periodic.

[0040] The main driving assembly 6 includes a transmission disc 8, a driving motor 9 and a driving sleeve 10. The transmission disc 8 is arranged on the main base plate 5. The transmission disc 8 is annularly evenly provided with disc circular holes 14 and disc guide rods 15. The driving motor 9 is arranged on the main base plate 5. The driving sleeve 10 is fixedly connected to the output shaft of the driving motor 9. The driving sleeve 10 is rotatably arranged at the center position of the transmission disc 8.

[0041] The asynchronous transmission assembly 7 includes an asynchronous driving gear 11, an asynchronous driven gear 12 and a hollow sleeve rod 13. The hollow sleeve rod 13 is rotatably arranged in the circular hole portion 14 of the disc. The asynchronous driving gear 11 and the asynchronous driven gear 12 are arranged in groups. The transmission ratios of each group of asynchronous driving gears 11 and asynchronous driven gears 12 are different. A polygonal through hole 16 is provided in the center of the hollow sleeve rod 13.

[0042] By designing different transmission ratios of each group of asynchronous driving gears 11 and asynchronous driven gears 12, each group of non-periodic vibration driving components 3 can be reciprocated and extended with different periods. In this case, the top disc 44 will exhibit non-periodic swing vibrations, thereby simulating the vibration of the house, thereby achieving the technical effect of dynamically testing building models or small components on the vibration disc.

[0043] The synchronous reset and leveling mechanism 2 comprises a crankshaft assembly 17 and a crankshaft reset assembly 18 . The crankshaft assembly 17 is slidably disposed in the asynchronous transmission assembly 7 , and the crankshaft reset assembly 18 is sleeved on the outside of the crankshaft assembly 17 .

[0044] At the end of the vibration test, the telescopic ranges of each group of hydraulic telescopic assemblies 36 are not the same; therefore, by shifting the crankshaft fork 20, the original angle of the rotating ramp sleeve 22 is calibrated by using the lifting ramp sleeve 21 that can only be lifted but not rotated, so that the crankshaft body 19 after the rotation restriction is released can automatically rotate to an angle matching the lifting ramp sleeve 21 under the cooperation of the inclined surfaces of the lifting ramp sleeve 21 and the rotating ramp sleeve 22, thereby realizing the resetting of the non-periodic vibration drive assembly 3 and the anti-stuck telescopic control mechanism 4.

[0045] The crankshaft assembly 17 includes a crankshaft body 19 and a crankshaft fork 20. An eccentric rod 24 is provided in the middle position of the crankshaft body 19. A top round rod 25 and a bottom round rod 26 are respectively provided at both ends of the crankshaft body 19. A top polygonal rod 27 matching the polygonal through hole 16 is provided at the bottom of the top round rod 25. The top round rod 25 is snap-fitted and slidably arranged in the main base plate 5. The top polygonal rod 27 is snap-fitted and slidably arranged in the polygonal through hole 16. The top of the top polygonal rod 27 is provided with a slope portion that is conducive to entering the polygonal through hole 16. The top round rod 25 is rotatably arranged in the polygonal through hole 16. The crankshaft fork 20 is snap-fitted and slidably arranged on the disc guide rod 15. The crankshaft fork 20 is located above the crankshaft reset assembly 18.

[0046] By pressing the crankshaft fork 20, each group of crankshaft bodies 19 can be pressed down as a whole, so that the top polygonal rod 27 is disengaged from the polygonal through hole 16. At this time, the top round rod 25 rotates in the polygonal through hole 16, and the crankshaft body 19 is in a state of free rotation. At this time, the lifting ramp sleeve 21 limits the rotating ramp sleeve 22. No matter what angle the rotating ramp sleeve 22 is at before adjustment, it can be automatically reset, thereby realizing the reset of the non-periodic vibration drive component 3 and the anti-stuck telescopic control mechanism 4.

[0047] The crankshaft reset assembly 18 includes a lifting ramp sleeve 21, a rotating ramp sleeve 22 and a support spring 23. The rotating ramp sleeve 22 is fixed to the bottom round rod 26. The lifting ramp sleeve 21 is evenly distributed in an annular manner with bottom lifting guide rods 46. The lifting ramp sleeve 21 is slidably engaged with the main bottom plate 5 through the bottom lifting guide rods 46. The support spring 23 is arranged between the lifting ramp sleeve 21 and the main bottom plate 5. The lifting ramp sleeve 21 and the rotating ramp sleeve 22 are designed with chamfered surfaces for matching.

[0048] Through the elastic expansion and contraction of the supporting spring 23, the lifting ramp sleeve 21 can be allowed to be lifted and lowered to avoid blocking the rotation of the rotating ramp sleeve 22; and the lifting ramp sleeve 21 and the rotating ramp sleeve 22 can be kept close to each other at all times, so that the rotational reset of the rotating ramp sleeve 22 can be achieved through the sliding cooperation of the inclined surface.

[0049] The non-periodic vibration drive assembly 3 includes a hydraulic cylinder seat 28, a driving piston 29, a reinforced ball socket 30, a transmission connecting rod 31 and a hydraulic cylinder body 47. The hydraulic cylinder seat 28 is fixedly connected to the main base plate 5, the hydraulic cylinder body 47 is snap-fitted in the hydraulic cylinder seat 28, the driving piston 29 is snap-fitted and slidably arranged in the hydraulic cylinder body 47, the reinforced ball socket 30 is arranged on the driving piston 29, and the two ends of the transmission connecting rod 31 are respectively provided with a connecting rod annular portion 32 and a connecting rod ball head portion 34, the connecting rod ball head portion 34 is rotatably arranged in the reinforced ball socket 30, the connecting rod annular portion 32 is rotatably arranged on the eccentric rod 24, and the interior of the connecting rod annular portion 32 is provided with an arc inner wall 33.

[0050] The anti-stuck telescopic control mechanism 4 includes a ball joint 35 , a hydraulic telescopic assembly 36 and an elastic telescopic assembly 37 . The ball joint 35 is composed of a ball head and a ball socket. The hydraulic telescopic assembly 36 is arranged on the ball joint 35 , and the elastic telescopic assembly 37 is arranged on the hydraulic telescopic assembly 36 .

[0051] On the one hand, the anti-stuck telescopic control mechanism 4 can affect the angle of the top disc 44 by the extension and retraction of the hydraulic telescopic assembly 36. Through the extension and retraction of each group of hydraulic telescopic assemblies 36, the top disc 44 can be made to vibrate non-periodically. On the other hand, through the extension and retraction of the elastic telescopic sleeve 41, it can be ensured that the top disc 44 will not get stuck during the extension and retraction of each group of hydraulic telescopic assemblies 36.

[0052] The hydraulic telescopic assembly 36 includes a telescopic cylinder 38, a telescopic push rod 39 and a hydraulic pipeline 40. The ball joint 35 is arranged between the telescopic cylinder 38 and the hydraulic cylinder seat 28. The telescopic push rod 39 is slidably arranged in the telescopic cylinder 38. The telescopic push rod 39 is provided with a flange portion 45. The hydraulic pipeline 40 is arranged between the telescopic cylinder 38 and the hydraulic cylinder body 47.

[0053] The elastic telescopic assembly 37 includes an elastic telescopic sleeve 41, a support spring 42, an adjusting slider 43 and a top disc 44. The elastic telescopic sleeve 41 is slidably engaged with the end of the telescopic push rod 39, the support spring 42 is arranged between the elastic telescopic sleeve 41 and the flange portion 45, the ball joint 35 is arranged between the elastic telescopic sleeve 41 and the adjusting slider 43, the adjusting slider 43 is arranged in the top disc 44, and the adjusting slider 43 can slide and lock on the top disc 44.

[0054] By adjusting the position of the adjusting slider 43 on the top disc 44, the weight of the influence of the hydraulic telescopic component 36 on the swing of the top disc 44 when it is extended and retracted can be changed, and then the maximum swing amplitude of the top disc 44 can be adjusted and set. By changing the rotation speed of the driving motor 9, the swing speed can be adjusted and set; by flexibly setting the swing speed and amplitude, different inspection conditions can be simulated and tested.

[0055] When in use, the user first needs to install and fix the building structure component to be tested on the top disc 44. If the structure component is too large to be installed, a proportional test model is fixed on the top disc 44 to perform a dynamic test on it.

[0056] When the drive motor 9 is started and the drive sleeve 10 is rotated by the drive motor 9, the hollow sleeve rod 13 can be rotated through the meshing transmission between the asynchronous drive gear 11 and the asynchronous driven gear 12. Since the transmission ratios between each group of asynchronous drive gears 11 and the asynchronous driven gears 12 are different, the rotation speeds of each group of hollow sleeve rods 13 are different. In the test state, the crankshaft body 19 is connected to the hollow sleeve rod 13 through the top polygonal rod 27, so when the hollow sleeve rod 13 rotates, it will bring the crankshaft body 19 to rotate. At this time, the rotating ramp sleeve 22 rotates with the crankshaft body 19, and the lifting ramp sleeve 21 avoids the position by lifting itself. Through the hinge of the eccentric rod 24 and the connecting rod annular portion 32, when the crankshaft body 19 rotates, it can drive the driving piston 29 to slide back and forth in the hydraulic cylinder body 47 through the transmission connecting rod 31, and the telescopic cylinder 38 and the hydraulic cylinder body 47 are connected by a hydraulic pipeline 40, so at this time the telescopic push rod 39 will also reciprocate and telescope in the telescopic cylinder 38; the asynchronous extension and retraction of the telescopic push rod 39 can cause the top disc 44 to deflect, and the extension and retraction periods of each group of telescopic push rods 39 are different, which can make the anti-stuck telescopic control mechanism 4 present non-periodic vibration.

[0057] By adjusting the position of the adjusting slider 43 on the top disc 44, the weight of the influence of the hydraulic telescopic component 36 on the swing of the top disc 44 when it is extended and retracted can be changed, and then the maximum swing amplitude of the top disc 44 can be adjusted and set. By changing the rotation speed of the driving motor 9, the swing speed can be adjusted and set; by flexibly setting the swing speed and amplitude, different inspection conditions can be simulated and tested.

[0058] Through non-periodic vibration, dynamic testing of small building structure components or models can be carried out; after the test is completed, the top disc 44 may remain in a non-horizontal position. At this time, it is necessary to reset the top disc 44 as a whole by independently resetting each group of hydraulic telescopic components 36.

[0059] At this time, it is only necessary to manually press down the crankshaft fork 20, and the crankshaft body 19 will descend together with the crankshaft fork 20. When the top polygonal rod 27 is disengaged from the polygonal through hole 16, the top round rod 25 rotates in the polygonal through hole 16, and the bottom round rod 26 rotates in the main bottom plate 5. Therefore, the crankshaft body 19 can actually rotate freely at this time; and because the lifting ramp sleeve 21 has a tendency to be close to the rotating ramp sleeve 22 under the elastic force of the supporting spring 23, the rotating ramp sleeve 22 will eventually be reset to an angle that fits the inclined surface of the lifting ramp sleeve 21 through the supporting of the lifting ramp sleeve 21. In this process, the non-periodic vibration drive assembly 3 and the anti-jamming telescopic control mechanism 4 will also be reset along with the rotation of the crankshaft body 19.

[0060] Then stop pressing the crankshaft fork 20, the crankshaft fork 20 and the crankshaft body 19 will rise under the elastic force of the top support spring 23, and the top polygonal rod 27 can easily enter the polygonal through hole 16 through the oblique guide portion at the top of the top polygonal through hole 16 and form a snap connection with the polygonal through hole 16; During this process, the crankshaft body 19 may rotate very slightly so that the top polygonal rod 27 is adjusted to an angle matching the polygonal through hole 16 , but this small rotation will not have a significant effect on the horizontality of the top disc 44 .

[0061] As another new embodiment of the present invention, the influence of the top polygonal rod 27's own rotation on the top disc 44 that has been reset can be reduced during the process of the top polygonal rod 27 re-entering the polygonal through hole 16. The top polygonal rod 27 and the polygonal through hole 16 can be clearance-matched, combined with the number of sides of the polygonal through hole 16. This can ensure that the hollow sleeve rod 13 can rotate with the crankshaft body 19 when it rotates, and can also allow the top polygonal rod 27 to smoothly enter the polygonal through hole 16 after the reset is completed.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
