[0043] Collapse is a geological phenomenon in which rock and soil on a relatively steep slope suddenly break away from the parent body under the action of gravity, roll and accumulate at the foot of the slope. Collapse is one of the common geological disasters in mountainous areas. It has a high occurrence frequency, strong suddenness, large randomness, various forms of rolling stone movement, great difficulty in prevention. Sometimes it will smash and bury houses and other engineering facilities, often causing great damage to buildings in mountainous areas, endangering the life and property safety of people in mountainous areas. It is a type of geological disaster that needs to be focused on preventing in mountainous areas. Therefore, studying the impact of collapsing rocks can provide a certain theoretical basis for the assessment of geological disaster risks, and corresponding solutions can be made according to the experimental results, reducing the disaster coefficient brought by collapsing rocks to humans to a certain extent. However, in existing simulation experimental devices for collapsing rocks, most of the structures are of fixed design, and the slope angle cannot be changed, resulting in relatively single experimental measurement results and unconvincing experimental result values.

[0044] To make up for the above deficiencies, the present invention provides a device for measuring the impact force of collapsing rocks, aiming to improve the problem that in existing simulation experimental devices for collapsing rocks, most of the structures are of fixed design, the slope angle cannot be changed, resulting in relatively single experimental measurement results and unconvincing experimental result values.

The elastic member 220 can be accommodated in the installation hole 212. Specifically, the number of the installation holes 212 and the elastic members 220 is multiple and evenly distributed along the circumferential direction of the installation barrel 210. The elastic member 220 can be any one of a spiral spring, a gas spring and a rubber spring. An insertion groove 211 is formed at the upper end of the installation barrel 210.

The right side of the simulation board 360 is fixedly installed on the left end of the fourth fixing seat 350 by bolts. The right end of the second bracket 370 is fixedly installed on the left side of the simulation board 360 by bolts. Specifically, a scale plate 112 is fixedly installed on the upper surface of the base 110 by bolts. The lower end of the simulation board 360 is rotatably installed on the scale plate 112 by a rotating shaft, which is convenient for observing and adjusting the angle of the simulation board 360. Scale lines 361 are fixedly installed on the simulation board 360 by welding. In a specific test, the height of the test falling stone can be determined according to the scale lines 361. The straight cylinder 380 is fixedly installed on the left end of the second bracket 370 by bolts. It should be noted that the straight cylinder 380 is arranged in a semi-circular arc shape, which is convenient for the lifting assembly 400 to lift the stone body 390. The stone body 390 is arranged at the upper end of the straight cylinder 380. A threaded opening 391 is provided on the stone body 390. The hanging ring 460 can be accommodated in the threaded opening 391 and can rotate along the threaded opening 391. In a specific application, the weight of the stone body 390 can be changed according to the test requirements.

[0049] Please refer to Figure 8 and Figure 9 , the lifting assembly 400 includes a mounting plate 410, a motor 420, a spool 430, a chain 440, a hook 450 and a hanging ring 460.

Through the above device, the stone body 390 is lifted to a specified position through the lifting function, reducing manual handling, improving work efficiency and also reducing the safety hazards existing in manual handling.

[0050] Please refer to Figure 8 and Figure 9, a through hole 141 is formed in the first bracket 140, the chain 440 can pass through the through hole 141 and can slide along the through hole 141.

Rotating plates 431 are fixedly installed on both sides of the spool 430 by bolts. The rotating plates 431 are arranged inside the second bracket 470 to prevent the chain 440 from rolling off.

[0051] It should be noted that in the existing collapse rockfall simulation experiments, it is often necessary to collect the rolling speed of the rockfall. Most of the test devices are mostly set as laser speed measuring instruments. When the rock mass is rolling, it is always in a moving state. The success rate of speed measurement by the speed measuring instrument is low and the difficulty is great. Therefore, other devices are also required to work simultaneously, which results in a large amount of resource waste.

[0052] Please refer to Figure 10 、 Figure 11 and Figure 12 , in an embodiment of the present invention, it further includes a timing component 500. The timing component 500 includes a first clamping plate 510, a second clamping plate 520, a timer 530, a first rack 540, a gear 550 and a second rack 560. The right end of the first clamping plate 510 is slidably installed on the upper end of the second bracket 370. The right end of the second clamping plate 520 is slidably installed at one end of the second bracket 370 away from the first clamping plate 510. The left end of the timer 530 is fixedly installed on the left end of the first clamping plate 510 by bolts, and the right end of the timer 530 is fixedly installed on the left end of the second clamping plate 520 by bolts. A first fixing groove 511 is formed at the right end of the first clamping plate 510. The left end of the first rack 540 is fixedly installed inside the upper end of the first fixing groove 511 by bolts. The gear 550 is in transmission connection with the first rack 540. A second fixing groove 521 is formed at the right end of the second clamping plate 520. The right end of the second rack 560 is fixedly installed inside the lower end of the second fixing groove 521 by bolts. The second rack 560 is in transmission connection with the gear 550. The right end of the first rack 540 can be accommodated in the second fixing groove 521, and the left end of the second rack 560 can be accommodated in the first fixing groove 511. A turning handle 551 is fixedly installed on one side of the gear 550. Through the above device, the clamping function of the rock mass 390 can be realized and the timing function can also be realized.

[0053] Specifically, the working principle of the impact force measuring device for collapse rockfall: By moving the first bracket 140, the first bracket 140 drives the connecting frame 133 to move, and then the connecting frame 133 drives the slider 132 to move on the slide rail 131;

[0054] When the collapsing rock hits the mounting cover 230, the mounting cover 230 moves downward into the insertion slot 211, and the elastic member 220 moves downward, thereby activating the sensor 240. When the rock is removed, the elastic member 220 moves upward, and thus the mounting cover 230 moves upward to return to its original state;

[0055] When slope adjustment is required, the first driving member 330 is activated. Then, the first driving member 330 drives the third fixed seat 340 to move. Then, the third fixed seat 340 drives the fourth fixed seat 350 to move. Then, the fourth fixed seat 350 drives the simulation board 360 to rotate and move on the scale board 112. Then, the simulation board 360 drives the second bracket 370 to move. Then, the second bracket 370 drives the straight cylinder 380 to move, thereby changing the slope of the overall device;

[0056] When the stone body 390 needs to be lifted to the moving height, the motor 420 is activated. Then, the motor 420 drives the spool 430 to rotate. Then, the spool 430 drives the chain 440 to move up and down. Then, the chain 440 drives the hook 450 to move up and down. Then, the hook 450 drives the lifting ring 460 to move up and down. Then, the lifting ring 460 drives the stone body 390 to move up and down;

[0057] When the stone body 390 to be measured is placed on the timing component 500, the first clamping plate 510 and the second clamping plate 520 clamp and fix it. At this time, the hook 450 is disengaged from the lifting ring 460. By rotating the turning handle 551, the turning handle 551 drives the gear 550 to rotate. The gear 550 is in transmission connection with the first rack 540 and the second rack 560. Then, the gear 550 drives the first rack 540 to move leftward, and the gear 550 drives the second rack 560 to move rightward. Then, the first rack 540 drives the first clamping plate 510 to move leftward, and the second rack 560 drives the second clamping plate 520 to move rightward. Then, while the stone body 390 is released, the timer 530 is started. When the stone body 390 hits the force measuring component 200, the timer 530 stops timing, thereby realizing the timing function.

[0058] It should be noted that the specific model specifications of the elastic member 220, the sensor 240, the first driving member 330, the motor 420, and the timer 530 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0059] The power supply and its principle of the elastic member 220, the sensor 240, the first driving member 330, the motor 420, and the timer 530 are clear to those skilled in the art and will not be described in detail here.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
