Description

Technical Field

[0001] This application relates to the technical field of dangerous rock collapse simulation devices, and more specifically, to a high-position dangerous rock collapse test simulation device. Background Art

[0002] Dangerous rock collapse is one of the common geological disasters in mountainous areas. It is characterized by strong suddenness and great destructive power, often causing serious harm to transportation facilities, residential areas, engineering construction, etc. In order to deeply study the formation mechanism, movement process and failure law of dangerous rock collapse, so as to better carry out geological disaster prediction, early warning and prevention work, it is necessary to carry out indoor simulation tests of dangerous rock collapse. High-position dangerous rock masses have the characteristics of large quantity, large scale, complex types, high occurrence frequency and high harm degree, seriously affecting the surrounding construction. When simulating the collapse of dangerous rock masses, by simulating the state of the rock mass falling along the slope, the speed and impact force of the rock mass falling to the lower part are recorded, so as to judge the harm caused by the collapse of dangerous rock masses. However, there are some deficiencies in the existing dangerous rock collapse test simulation devices. For example, it is difficult to accurately control the test parameters, and it cannot well simulate the slope gradient of the slope when the dangerous rock falls, so the influence of the slope angle on the impact force of the dangerous rock mass when it falls cannot be obtained.

[0042] Next, a high-position dangerous rock collapse test simulation device according to an embodiment of the present application will be described with reference to the drawings.

[0043] Please refer to Figures 1 to 13 , a high - altitude dangerous rock collapse test simulation device according to an embodiment of the present application, comprising:

[0044] A support frame 1, inside which there is a simulated slope 2. The lower end of the simulated slope 2 is rotatably installed between the front and rear side walls of the support frame 1. The front end of the rotation axis of the simulated slope 2 penetrates the side wall of the support frame 1 and is connected to a first bevel gear 9. Between the front and rear side walls on the right part of the support frame 1, a test support plate 8 is rotatably installed;

[0045] A slope adjustment assembly 3, which is installed at the left end inside the support frame 1 and can adjust the angle of the simulated slope 2;

[0046] An impact assembly 4, which is movably arranged on the test support plate 8;

[0047] Impact test assemblies 5, there are two groups of impact test assemblies 5, which are respectively fixedly installed on the front and rear side walls at the right end of the support frame 1. The front and rear ends of the impact assembly 4 are respectively connected to the corresponding impact test assemblies 5;

[0048] A return assembly 7, which is installed on the front side wall of the support frame 1. After the impact assembly 4 moves to the right, the return assembly 7 meshes with the first bevel gear 9. When the impact assembly 4 moves to the leftmost end, the return assembly 7 disengages from the first bevel gear 9;

[0049] A discharging assembly 6, which is installed on the lower side at the middle position of the support frame 1. The slope adjustment assembly 3 can drive the discharging assembly 6 to work, so that the left end of the test support plate 8 rotates downward for discharging.

[0050] In the test process of the present invention, the inclination angle of the simulated slope 2 can be changed through the slope adjustment assembly 3, and in cooperation with the impact assembly 4 and the impact test assemblies 5, the impact force magnitude of the simulated dangerous rock mass at different angles can be obtained, so as to obtain the influence of the rolling of the dangerous rock mass at different slopes on the surrounding area. Through the return assembly 7, when adjusting the angle of the simulated slope 2, the return assembly 7 can be used to make the impact assembly 4 return to the initial position, so as to facilitate the next simulation test. And through the discharging assembly 6, when adjusting the angle of the simulated slope 2, the dangerous rock mass on the test support plate 8 can be automatically unloaded and return to the horizontal state after being automatically unloaded, preparing for the next simulation test.

[0051] The present invention links the slope adjustment component 3, the return component 7, the impact component 4, the impact test component 5 and the unloading component 6 together, and can complete the angle adjustment of the test device, the cleaning of the test dangerous rock body and the return of the impact component 4 in one step after the test is completed, so that one driving component can be fully utilized to complete multiple working steps, greatly saving the labor of the staff and improving work efficiency.

[0052] See also Figure 1 , Figure 2 and Figure 4 The slope adjustment assembly 3 includes a mounting vertical plate 31, a support plate 32, a drive motor 33, a drive screw 34, a movable adjustment member 35 and an auxiliary support assembly 39. The mounting vertical plate 31 is vertically fixedly mounted on the left end side wall of the support frame 1. The left side surface of the mounting vertical plate 31 is symmetrically mounted with support plates 32. The drive motor 33 is fixedly mounted on the upper support plate 32. A drive screw 34 is rotatably mounted between the upper and lower support plates 32. The upper end of the drive screw 34 is connected to the output end of the drive motor 33. The drive screw 34 is connected to the movable adjustment member 35. The movable adjustment member 35 The right side is connected to the simulated slope 2, and the front and rear ends of the right side of the movable adjustment member 35 are respectively connected with auxiliary support assemblies 39, and the lower end of the auxiliary support assembly 39 is installed on the side wall of the support frame 1, and a rotating vertical shaft 36 is rotatably installed on the lower side of the lower support plate 32, and the upper end of the rotating vertical shaft 36 is connected to the lower end of the driving screw 34, and a double-groove pulley 37 and a first pulley 38 are sequentially installed on the rotating vertical shaft 36. When in use, the driving motor 33 can drive the driving screw 34 to rotate, and the rotation of the driving screw 34 can drive the movable adjustment member 35 to move up and down. When the movable adjustment member 35 moves up and down, the inclination angle of the simulated slope 2 can be adjusted, so as to simulate the impact force when the dangerous rock falls at different inclination angles during the test process, and the right end of the movable adjustment member 35 can be supported by the auxiliary support assembly 39 during the up and down movement of the movable adjustment member 35 to ensure that the movable adjustment member 35 can always maintain balance.

[0053] Specifically, the moving adjustment member 35 includes a first C-shaped frame 351, a second C-shaped frame 352, and a moving plate 353. The first C-shaped frame 351 is arranged on the left side of the installation vertical plate 31, and the second C-shaped frame 352 is arranged on the right side of the installation vertical plate 31. The end of the first C-shaped frame 351 is fixedly connected to the middle side wall of the second C-shaped frame 352. The moving plate 353 is movably arranged inside the second C-shaped frame 352. Sliding grooves 354 are formed on the front and rear side walls of the second C-shaped frame 352. Sliding bars 355 are fixedly installed on the front and rear side walls of the moving plate 353 respectively. The sliding bars 355 are movably clamped in the sliding grooves 354. The right end of the moving plate 353 is rotatably connected to the upper end of the simulated slope body 2. By fixedly connecting the first C-shaped frame 351 and the second C-shaped frame 352 together and arranging the installation vertical plate 31 in the gap between the first C-shaped frame 351 and the second C-shaped frame 352, the first C-shaped frame 351 and the second C-shaped frame 352 can move up and down along the installation vertical plate 31 during the moving process, and the first C-shaped frame 351 and the second C-shaped frame 352 are prevented from rotating. By movably clamping the sliding bars 355 on the moving plate 353 in the sliding grooves 354, the moving plate 353 can slide left and right inside the second C-shaped frame 352. Thus, during the up and down movement of the moving adjustment member 35, the moving plate 353 can be automatically adjusted left and right so that the upper end of the simulated slope body 2 is always connected to the right end of the moving plate 353.

[0054] The auxiliary support assembly 39 includes a fixed plate 391, a threaded sleeve 392, a lead screw 393, a second pulley 394, and a first transmission belt 395. The lead screw 393 is threadedly installed in the threaded sleeve 392. The lower end of the lead screw 393 is rotatably connected to the fixed plate 391. The fixed plate 391 is fixedly installed on the outer side wall of the support frame 1. The upper end of the threaded sleeve 392 is fixedly connected to the right end of the second C-shaped frame 352. The lower end of the lead screw 393 passes through the fixed plate 391 and is connected to the second pulley 394. A first transmission belt 395 is installed between the second pulley 394 and the double-groove pulley 37 for transmission. Under the driving action of the first transmission belt 395, the lead screw 393 can rotate synchronously with the driving screw 34. When the lead screw 393 rotates, the threaded sleeve 392 can be driven to move up and down, so that the auxiliary support assembly 39 can adjust its length following the movement of the moving adjustment member 35 and always support the moving adjustment member 35.

[0055] And before the test, the moving adjustment member 35 can be moved to the lowermost end through the adjustment of the slope body adjustment assembly 3, which is convenient for placing the test dangerous rock mass on the moving plate 353 at a lower position, so that no other hoisting mechanism is needed during the placement of the dangerous rock mass, making the placement of the dangerous rock mass more convenient.

[0056] Please refer to Figure 1 、 Figure 8, Figure 9 , Figure 10 , Figure 11 and Figure 12 , the impact test assembly 5 includes a rectangular box 51, a sliding rod 52, a slider 53, a first spring 54 and a limiting strip 55. The rectangular box 51 is fixedly installed on the right side wall of the support frame 1. A first strip-shaped opening 511 is formed on the side surface of the rectangular box 51 close to the impact assembly 4, and a second strip-shaped opening 512 is formed at the bottom of the rectangular box 51. A sliding rod 52 is installed between the left and right side walls inside the rectangular box 51. A slider 53 is slidably installed on the sliding rod 52. A first spring 54 is sleeved on the sliding rod 52 on the right side of the slider 53. A limiting strip 55 is rotatably installed at a position in the rectangular box 51 far from the first strip-shaped opening 511. A plurality of limiting buckles 551 are evenly formed on the side of the limiting strip 55 close to the sliding rod 52. A telescopic rod 531 is fixedly installed on the side surface of the slider 53 close to the limiting strip 55. The end of the telescopic rod 531 is fixedly connected with a trapezoidal block 532. The left end of the limiting strip 55 extends out of the rectangular box 51 and is connected with a clamping sleeve 56;

[0057] Specifically, the impact assembly 4 includes a strip-shaped plate 41 and an impact plate 42. The strip-shaped plate 41 is movably arranged on the test support plate 8. An impact plate 42 is fixedly installed on the upper surface of the strip-shaped plate 41. The front and rear ends of the strip-shaped plate 41 are respectively fixedly connected to the corresponding sliders 53. When the simulated unstable rock on the moving adjustment member 35 falls, the unstable rock impacts downward along the simulated slope 2, pushing the impact assembly 4 to move rightward. The moving distance of the impact assembly 4 changes with the impact force of the unstable rock. During the rightward movement of the impact assembly 4, it will overcome the elastic force of the first spring 54 to drive the slider 53 to move along the sliding rod 52. And during the movement, the telescopic rod 531 installed on the side of the slider 53 will continuously contract and extend until the impact assembly 4 stops. At this time, the trapezoidal block 532 is quickly clamped in the corresponding limiting buckle 551 on the limiting strip 55. Under the clamping action of the trapezoidal block 532 and the limiting buckle 551, the impact assembly 4 can be fixed, preventing the impact assembly 4 from shifting under the action of the rebounding force of the first spring 54, which is convenient for the test personnel to record data.

[0058] A limiting mounting plate 57 is fixedly installed on the lower side surface of the slider 53. The limiting mounting plate 57 is movably clamped in the second strip-shaped opening 512. A push rod 58 is fixedly installed on the lower left side surface of the limiting mounting plate 57. When the impact assembly 4 is impacted by the unstable rock and moves rightward, the limiting mounting plate 57 also moves rightward together with the slider 53. At this time, the push rod 58 can release the thrust on the return assembly 7, and the return assembly 7 can move rightward. At this time, the second bevel gear 76 on the return assembly 7 can be engaged with the first bevel gear 9.

[0059] After the tester finishes the test and needs to change the angle of the simulated slope body 2 for the next test, when adjusting the angle of the simulated slope body 2, the first bevel gear 9 can drive the return component 7 to rotate. Through the return component 7, the limiting strip 55 can be driven to rotate, so that the trapezoidal block 532 moves out of the limiting bayonet 551 on the limiting strip 55. At this time, the impact component 4 can return to its initial position under the action of the first spring 54.

[0060] The right end of the limiting strip 55 extends out of the rectangular box 51 and is connected with a third pulley 59. A second transmission belt 510 is installed between the front and rear third pulleys 59. Through the transmission of the second transmission belt 510, the front and rear limiting strips 55 can be rotated simultaneously, so that the trapezoidal blocks 532 on both sides of the impact component 4 move out of the limiting bayonet 551 at the same time.

[0061] Specifically, please refer to Figure 13 The return component 7 includes a mounting frame 71, a guide rod 72, a second spring 73, a rectangular plate 74, a rotating rod 75, a second bevel gear 76 and a clamping block 77.

The end of the rotating rod 75 is fixedly connected with a clamping block 77. After the impact component 4 moves to the right, at this time, the push rod 58 can release the thrust on the return component 7, and the return component 7 can move to the right. Specifically, the rectangular plate 74 moves to the right under the action of the second spring 73, the clamping block 77 is inserted into the clamping sleeve 56, and the second bevel gear 76 meshes with the first bevel gear 9. When the slope adjustment component 3 adjusts the angle of the simulated slope body 2, the first bevel gear 9 can drive the second bevel gear 76 to rotate. Under the transmission action of the clamping block 77 and the clamping sleeve 56, the limiting strip 55 can be rotated. During the rotation of the limiting strip 55, the trapezoidal block 532 can move out of the limiting bayonet 551.

[0062] Please refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 7The unloading assembly 6 includes a bending plate 61, a horizontal rotating shaft 62, a toggle plate 63, a rotating sleeve 64, a moving column 65, a fixing bar 66, an L-shaped plate 67, a round rod 68 and a third spring 69. The bending plate 61 is fixedly installed on the lower side of the supporting frame 1. The rear side wall of the bending plate 61 is rotatably installed with a horizontal rotating shaft 62, and the toggle plate 63 is fixedly connected to the horizontal rotating shaft 62. The end of the horizontal rotating shaft 62 is fixedly installed with a rotating sleeve 64. An S-shaped sliding groove 641 is provided on the side wall of the rotating sleeve 64. A moving column 65 is movably installed in the rotating sleeve 64, and the moving column 65 extends into the rotating sleeve 64. One end of the movable column 65 is fixedly connected with a protrusion 651, and the protrusion 651 is movably clamped in the S-shaped slide groove 641. A fixing strip 66 is also installed at the bottom of the bending plate 61. The left and right ends of the fixing strip 66 are respectively fixedly connected with L-shaped plates 67. The left and right sides of the movable column 65 are symmetrically provided with guide slide grooves 652. The ends of the L-shaped plates 67 are clamped into the guide slide grooves 652. The front side surface of the fixing strip 66 is fixedly connected with a round rod 68. The round rod 68 is sleeved with a push plate 610. The round rod 68 is sleeved with a third spring 69 at the rear side of the push plate 610. The upper end of the push plate 610 is fixedly connected to the front end of the movable column 65.

[0063] A cam 611 is rotatably mounted on the upper side of the middle position of the bending plate 61. The lower end of the rotating shaft of the cam 611 penetrates the bending plate 61 and is connected to a one-way transmission component 615. An L-shaped mounting plate 614 is fixedly mounted on the lower side of the middle position of the bending plate 61. A fourth pulley 612 is rotatably mounted on the L-shaped mounting plate 614. A third transmission belt 613 is installed between the fourth pulley 612 and the first pulley 38 for transmission.

[0064] The one-way transmission assembly 615 includes a driven shaft 6151, a driven sleeve 6152, a first one-way clutch 6154, a second one-way clutch 6156 and a driving shaft 6158. The upper end of the driven shaft 6151 is fixedly connected to the rotating shaft of the cam 611, the lower end of the driven shaft 6151 is fixedly connected to the driven sleeve 6152, and the inner part of the driven sleeve 6152 is evenly installed with meshing teeth 6153. The lower end of the driving shaft 6158 is fixedly connected to the fourth pulley 612, and the first one-way clutch 6154 and the second one-way clutch 6156 are installed on the driving shaft 6158 in sequence, and the first one-way clutch 6154 and the second one-way clutch 6156 are installed in sequence. The clutch 6154 and the second one-way clutch 6156 are both located in the driven sleeve 6152. The transmission directions of the first one-way clutch 6154 and the second one-way clutch 6156 are opposite. The inner rings of the first one-way clutch 6154 and the second one-way clutch 6156 are both fixedly connected to the driving shaft 6158. The outer ring of the first one-way clutch 6154 is fixedly installed with a first gear ring 6155, and the outer ring of the second one-way clutch 6156 is fixedly installed with a second gear ring 6157. The first gear ring 6155 and the second gear ring 6157 are both meshed and connected with the meshing teeth 6153 in the driven sleeve 6152.

[0065] The driving shaft 6158 can rotate together with the fourth pulley 612. When the driving shaft 6158 rotates in the forward direction, it can drive the outer ring of the first one-way clutch 6154 to rotate, and then drive the driven sleeve 6152 to rotate through the first gear ring 6155. When the driving shaft 6158 rotates in the reverse direction, it can drive the outer ring of the second one-way clutch 6156 to rotate, and then drive the driven sleeve 6152 to rotate through the second gear ring 6157. When the push plate 610 moves forward under the rebound force of the third spring 69, the forward movement of the push plate 610 will drive the angle of the cam 611 to rotate slightly. Under the action of the one-way transmission component 615, the rotation of the cam 611 will not be transmitted to the fourth pulley 612, thereby avoiding affecting the slope adjustment component 3.

[0066] When the angle of the simulated slope 2 is adjusted by the slope adjustment component 3, the first pulley 38 can drive the fourth pulley 612 to rotate through the third transmission belt 613, and the cam 611 can be rotated through the transmission of the one-way transmission component 615. During the rotation of the cam 611, the push plate 610 and the moving column 65 can be pushed to move backward. During the movement of the moving column 65, under the action of the protrusion 651 and the S-shaped slide groove 641, the rotating sleeve 64 can rotate clockwise. At this time, after the toggle plate 63 rotates clockwise, its end cannot support the left end of the test support plate 8, and the left end of the test support plate 8 can rotate downward, and the dangerous rocks accumulated on it can fall to the left along the test support plate 8, thereby cleaning the upper surface of the test support plate 8.

[0067] When the angle adjustment of the simulated slope 2 is completed, the slope adjustment component 3 no longer transmits driving force to the cam 611, and the dangerous rock mass on the test support plate 8 is completely removed. Under the action of the third spring 69, the push plate 610 gradually moves to the front side. At this time, the protrusion 651 is embedded and moved together, and drives the rotating sleeve 64 to rotate counterclockwise during the movement. At this time, the toggle plate 63 can be in a vertical state again to prop up the test support plate 8 again.

[0068] Specifically, the working principle of the high-position dangerous rock collapse test simulation device is as follows: when in use, first adjust the inclination angle of the simulated slope 2 through the slope adjustment component 3, then place the test dangerous rock on the movable plate 353 on the movable adjustment component 35, and then let the test dangerous rock fall, so that the test dangerous rock can roll down along the simulated slope 2. When it rolls to the lower end of the simulated slope 2, it can hit the impact component 4. During the movement of the impact component 4 to the right, it will overcome the elastic force of the first spring 54 to drive the slider 53 to move along the slide rod 52, and during the movement, the telescopic rod 531 installed on the side of the slider 53 will continuously shrink and extend until the impact component 4 stops. At this time, the trapezoidal block 532 is quickly clamped in the corresponding limit bayonet 551 on the limit strip 55. Under the clamping action of the trapezoidal block 532 and the limit bayonet 551, the impact component 4 can be fixed to prevent the impact component 4 from shifting under the rebound force of the first spring 54, which is convenient for the test personnel to record data.

[0069] When the test personnel have completed recording the test data and are about to conduct the next round of tests, the slope adjustment component 3 is used to adjust the inclination angle of the simulated slope 2. Since the impact component 4 is moved to the right after being hit by the dangerous rock, the limit mounting plate 57 also moves to the right along with the slider 53. At this time, the push rod 58 can release the thrust on the return component 7, and the return component 7 can move to the right. At this time, the second bevel gear 76 on the return component 7 can engage with the first bevel gear 9. Therefore, when the simulated slope 2 rotates, the first bevel gear 9 can drive the second bevel gear 76 to rotate. Under the transmission action of the clamping block 77 and the clamping sleeve 56, the limit bar 55 can be rotated. During the rotation of the limit bar 55, the trapezoidal block 532 can be moved out of the limit bayonet 551. At this time, the impact component 4 can return to its initial position under the action of the first spring 54.

[0070] When the slope adjustment component 3 adjusts the angle of the simulated slope 2, the first pulley 38 can drive the fourth pulley 612 to rotate through the third transmission belt 613, and the cam 611 can be rotated through the transmission of the one-way transmission component 615. During the rotation of the cam 611, the push plate 610 and the moving column 65 can be pushed to move backward. During the movement of the moving column 65, under the action of the protrusion 651 and the S-shaped slide groove 641, the rotating sleeve 64 can rotate clockwise. At this time, after the toggle plate 63 rotates clockwise, its end cannot support the left end of the test support plate 8, and the left end of the test support plate 8 can rotate downward, and the dangerous rocks accumulated on it can fall to the left along the test support plate 8, thereby cleaning the upper surface of the test support plate 8.
