Description

Technical Field

[0001] The utility model relates to the technical field of interception facilities, in particular to a rock rolling interception device for a spoil yard. Background Art

[0002] Rolling rocks generated during operations in mine dumps pose a significant threat to facilities below the slope's toe. After breaking free from the slope's surface, these rocks rapidly move downward through a variety of motions, including falling, rebounding, bouncing, rolling, or sliding, before settling near the slope's toe. If human activity or human-built structures are within their reach, potentially causing damage, this can constitute a rockfall hazard. Currently, research on mine dumps in China focuses primarily on stability and debris flow prevention, while relatively little research has been conducted on rockfall. With increasing mining land availability and technological advancements, high- and steep-sided dumps are bound to increase in number. To prevent rockfall from posing a threat to underlying equipment, facilities, and personnel, in-depth research into the movement patterns and hazard prevention of rockfall is necessary to prevent future hazards.

[0003] Rockfall in mountainous areas often exhibits sudden, frequent, and random patterns that are difficult to predict, posing a significant threat to humans. When the source of rockfall is difficult to access and the impact energy is high, using rock dams or other rock-blocking devices to intercept the rockfall is an effective means of preventing it. Conventional protection measures for areas at risk from rockfall include passive or active netting. However, due to the high kinetic energy of rockfall as it falls down a slope, passive netting is less effective and can provide limited protection for equipment behind the netting.

[0004] The publication number is: CN219527382U, and the name is: A device for intercepting rolling stones on the slope of an open-pit mine, comprising a base, fixedly connected to fixed seats on both sides of the base, a first screw threadedly sleeved on the fixed seat, a knob fixedly connected to the top surface of the base, a rotating seat fixedly connected to the rotating seat, an interception main board rotatably connected to the rotating seat, and a heightening machine provided on the top of the interception main board. In the present utility model, the base is fixed by the first screw, and the rear support mechanism is used to support the rear of the interception main board. When a rolling stone hits the interception front plate, the first spring is used to reduce the impact force, and the interception main board is driven to rotate backward, and the second spring on the rear support mechanism is used to reduce the impact force again, thereby achieving the function of offsetting the impact force of the rolling stone, and improving the working quality of the device for intercepting rolling stones on the slope of an open-pit mine.

[0005] The above device can achieve the effect of intercepting rolling stones, but it has a complex structure, is difficult to install, and has high processing and manufacturing costs. When used in mountainous areas, the investment is too large. Utility Model Content

[0006] The purpose of the utility model is to provide a rock rolling interception device for a spoil dump with reasonable structural design, novel concept, low processing and manufacturing cost, simple structure, convenient installation, safe and reliable use, and which reduces the impact of rock rolling by changing the movement direction of the rock rolling.

[0007] The utility model discloses a rock rolling intercepting device for a spoil field, comprising a base. The base surface is provided with an upper surface. One side of the base and the upper surface is provided with an arc edge, and the other side of the base and the upper surface is provided with a bevel edge.

[0008] The base is firmly installed and has a stable center of gravity. One side of the base is provided with a curved edge. During use, the curved base is installed in front of the monitoring room in the gully of the spoil dump to form a protective wall. The direction of movement of the rolling large debris is changed. When the rolling stone contacts the curved edge, the direction of movement of the rolling stone forms a certain angle with the curved edge, so that the curved edge provides centripetal force for the rolling stone. As the rolling stone rolls on the curved edge, the angle between the centripetal force and gravity continues to decrease and forms a certain angle with the direction of movement. Under the combined action of centripetal force and gravity, the direction of movement of the rolling stone continues to change, and finally rolls to the inside of the curved edge, thereby protecting the equipment and facilities behind the curved edge. The form of the curved edge reduces the impact on the monitoring equipment, is safe and reliable to use, has high safety performance, and plays a role in protecting the monitoring equipment and operators in the monitoring room. The beveled edge is provided to lower the overall center of gravity, ensuring that the main functions of the equipment and facilities are not affected by external influences such as earthquakes. Secondly, the beveled edge is provided to reduce the blind spot of the rear monitoring radar, providing a wider radar scanning area for slope monitoring.

[0009] The base comprises a short side and a long side, the surface of the short side is connected with an arc side, and the surface of the long side is connected with a bevel side.

[0010] The base includes short sides and long sides, which can improve the stability of the entire base, prevent the risk of tipping over due to the large size of the rolling stone, further improve the safety performance, and prolong the service life.

[0011] The length of the upper surface is smaller than the length of the base.

[0012] The length of the upper surface is 1 / 2 of the length of the base.

[0013] Setting the length of the upper surface to be smaller than the length of the base can fully ensure that the center of gravity of the base at the bottom is at the bottom, fully ensure the stability of the entire rolling stone interception device, prevent the entire device from tipping over, and make it more stable, safe and reliable after installation and use.

[0014] The height of the hypotenuse is 2 / 3 of the height of the base.

[0015] The height of the hypotenuse is set to 2 / 3 of the base height to further lower the overall center of gravity, ensuring that the main function of the rock rolling interception device is not affected when the equipment and facilities are affected by external earthquakes, etc.; the blind spot of the rear monitoring radar is reduced, providing a wider radar scanning area for slope monitoring.

[0016] The upper end of the arcuate side is connected to the end of the upper surface, the lower end of the arcuate side is connected to the surface end of the short side, and the height of the upper end of the arcuate side is lower than the height of the lower end of the arcuate side.

[0017] The upper end height of the arc edge is set lower than the lower end height of the arc edge, which reduces the impact of large pieces of rolling debris on the monitoring equipment by changing the direction of movement. It is safe and reliable to use, with high safety performance, and can also improve the stability of the entire rolling stone interception device.

[0018] Beneficial effects of the utility model:

It is safe and reliable to use, with high safety performance, and plays a role in protecting the monitoring equipment and operators in the monitoring room. The bevel is set to lower the overall center of gravity and ensure that the main functions of the equipment and facilities are not affected when affected by external earthquakes. Secondly, the bevel is set to reduce the blind spot of the rear monitoring radar and provide a wider radar scanning area for slope monitoring.

[0020] 2) The base includes short sides and long sides, which can improve the stability of the entire base, prevent the risk of tipping over due to the large size of the rolling stone, further improve the safety performance and prolong the service life.

[0021] 3) Setting the length of the upper surface to be smaller than the length of the base can fully ensure that the center of gravity of the base at the bottom is at the bottom, fully ensuring the stability of the entire rolling stone interception device, preventing the entire device from tipping over, and making it more stable, safe and reliable after installation and use.
