Description

[0002] Against the background of accelerated construction of many engineering facilities, the stability problem of locked rock slopes has become increasingly prominent. The root cause lies in the failure of unlocking the locked section. In order to deeply understand this problem, it is particularly important to conduct loading tests on locked slope models. However, in the loading devices of traditional slope model tests, the slope model is usually loaded by a hydraulic press or a pressing device, which requires a large amount of electricity and cannot provide a large output pressure with a small force, resulting in high cost of use. At present, on the basis of the traditional primary lever, a secondary lever loading method is used through the cumulative loading method. The smaller counterweight load is amplified and applied to the slope model using the lever principle, and weights are placed on the lever. The applied pressure is then increased using the lever principle, and then the top pressure plate of the model is driven downward to press the slope model for testing, saving electricity and reducing cost of use.

However, the height of the lever and the pressure plate cannot be adjusted, and cannot adapt to slope models of different heights.

[0042] Then, the arc-shaped slide rail 19 is placed on one side of the rotating groove 8, one end of the slider 20 is slidably connected to the arc-shaped slide rail 19, the other end of the slider 20 is fixedly connected to the rotating groove 8, the push-up component 21 is arranged on the base 1, the output end of the push-up component 21 is fixedly connected to the connecting block 22, and the connecting block 22 is fixedly connected to the arc-shaped slide rail 19.

[0043] Again, the two limit units are symmetrically arranged on the base 1; the fixed plate 23 is arranged above the base 1, the two ends of the multiple telescopic rods 25 are respectively fixedly connected to the fixed plate 23 and the movable plate 24, the two ends of the multiple springs 26 are respectively movably connected to the fixed plate 23 and the movable plate 24, the springs 26 are sleeved on the outside of the telescopic rods 25, and the multiple first adsorption mechanisms are arranged on the movable plate 24 and the movable seat 2. The fixed plate 23 supports the telescopic rods 25, the first adsorption mechanism is activated, and then docks and adsorbs with the movable seat 2, so that the movable seat 2 cannot move, and when the adsorption is cancelled, the springs 26 rebound, and the telescopic rods 25 follow the telescopic movement to maintain stability.

[0044] In addition, the movable seat 2 has a limiting hole 29, the metal column 27 is fixedly connected to the movable plate 24, the electromagnet 28 is arranged inside the limiting hole 29, and the metal column 27 and the electromagnet 28 attract each other. The movable plate 24 supports the metal column 27; when the movable seat 2 moves to the inside of the base 1, the limiting hole 29 is aligned with the metal column 27, and the electromagnet 28 is started and energized, and then the metal column 27 is adsorbed into the limiting hole 29 to complete the limiting; after the loading test is completed, the electromagnet 28 is de-energized, and the spring 26 rebounds, driving the movable plate 24 and the metal column 27 to reset.

[0045] Furthermore, the transport unit is mounted on one side of the base 1; the bracket 30 is mounted on one end of the base 1; the lateral moving component 31 is arranged below the bracket 30; the second lifting component 32 is arranged at the output end of the lateral moving component 31; the placement seat 33 is placed below the bracket 30; a plurality of weights 15 are placed on the placement seat 33; and the second adsorption mechanism is arranged at the output end of the second lifting component 32.

[0047] When using a loading device for a locking type rock slope model test of the present embodiment, the locking type rock slope model 3 is placed on the moving seat 2, and then moved to the inside of the base 1, and the electromagnet 28 is energized to suck the metal column 27 into the limiting hole 29 for limiting and fixing, thereby ensuring the stability of the loading test; the staff starts the first lifting component 5 according to the height of the locking type rock slope model 3 to adjust the appropriate height; then the second lifting component 32 is started to drive the second adsorption mechanism to move downward from the placement seat 3 3 absorbs the weight 15 inside, and then moves to the loading slot 13 through the movement of the lateral moving part 31 to place it, thereby increasing the weight; at this time, the rotating slot 8 is driven to rotate; the pressing plate 4 is moved down, and the rotating part 6 is started at the same time to adjust the angle of the pressing plate 4 so that the pressing plate 4 fits the top of the locking type rock slope model 3, and the locking type rock slope model 3 is fully loaded; after the test is completed, the moving seat 2 is removed, and the next slope model is replaced, and the loading position and angle are adjusted to test again, and the operation is repeated;

[0048] In the traditional method, when pressure is applied to the slope model, it cannot be adjusted. Once the angle above the model changes or the angle of the pressure plate 4 changes, the model and the pressure plate 4 cannot fit perfectly, which affects the test. However, the present application adjusts the pressure angle and height of the test so that no matter how the model angle changes, the pressure plate 4 can fit perfectly with the top of the model, and the weight 15 can be automatically added at any time. It has high flexibility in use and is suitable for the loading requirements of locking slope models of different sizes under various test conditions, which is more convenient for the test of the locking rock slope model 3.

[0049] The loading device for the locking type rock slope model test also includes a secondary accumulation component;

[0050] The secondary accumulation assembly includes two secondary lever frames 36, a secondary weight frame 37, a first rotating frame 38, a second rotating frame 39 and a third rotating frame 40. The two secondary lever frames 36 are sequentially arranged above the base, one end of the first rotating frame 38 is rotatably connected to the corresponding secondary lever frame 36, the secondary weight frame 37 is arranged at the other end of the first rotating frame 38, the two ends of the second rotating frame 39 are respectively rotatably connected to the corresponding secondary lever frame 36 and the bottom of the first rotating frame 38, the third rotating frame 40 is rotatably connected to the bottom of the second rotating frame 39, the third rotating frame 40 is sleeved on the outside of the rotating groove, and the bottom of the third rotating frame 40 is in contact with the locking type rock slope model 3.

[0051] The locking type rock slope model 3 includes a slope body 41 and a locking section 42. The locking section 42 is arranged on one side of the slope body 41, and the entire secondary cumulative assembly is supported by the secondary lever frame 36. The weight is placed in the secondary weight frame 37, and by increasing the weight, one end of the first rotating frame 38 rotates, driving the two ends of the second rotating frame 39 to rotate. At the same time, the second rotating frame 39 pushes the third rotating frame 40 downward to increase the dead weight of the slope body 41. Thus, through the cumulative secondary lever loading method, the lever principle is used to amplify the smaller counterweight load and apply it to the slope model. The output pressure is stable, the lever loading device has a small dead weight, is easy to process and manufacture, has a simple loading method, occupies a small test site, and does not require electricity during the loading process, so the use cost is low and the safety is high.

[0052] At the same time, the secondary accumulative lever is manually operated. During the test, after determining the size and deadweight of the locked rock slope model 3, the weight 15 is manually added to the specified weight to increase the deadweight of the slope 41, and the weight is no longer changed during the test. Therefore, the transport unit of the secondary accumulative lever is reduced to reduce costs. During the test, the transport unit is required to repeatedly add the weight 15 to continuously increase the weight to achieve the effect of loading and destruction. Therefore, the transport unit can automatically add weight to improve the test efficiency.
