Description

Technical Field

[0001] The invention relates to the technical field of protective devices, in particular to a protective device for blocking with rolling stones in layer slope blasting. Background Art

[0002] Blasting along the slope may produce rolling stones. In mining or construction projects, blasting technology will produce a lot of crushed stones and rock chips, which are sometimes thrown out by the force of the explosion and become rolling stones. This may pose a safety risk to workers and the surrounding environment. Therefore, when designing a blasting plan, it is usually considered how to control the generation and movement of rolling stones to ensure the safety of construction or mining;

[0003] In the prior art, a Chinese patent with the publication number "CN116952092A" discloses a rock rolling near-body blocking and protection device for slope blasting, including a first anchoring column and a second anchoring column. The first anchoring column is anchored at a downhill location close to the blasting point. Both side walls of the first anchoring column are fixedly connected with a first blocking net, and the meshes of the two first blocking nets are staggered. The first blocking net is used to block rocks that roll down and splash from low places. The second anchoring column is anchored at a downhill location of the first anchoring column. Both side walls of the second anchoring column are fixedly connected with a second blocking net, and the meshes of the two second blocking nets are staggered. The top height of the second blocking net is higher than the top height of the first anchoring column. A high-pressure water curtain is formed by a water curtain device, and the high-pressure water curtain impacts the surface of the rock rolling, reducing the kinetic energy of the rock rolling, thereby slowing down the impact force and speed of the rock rolling, and reducing the impact force on the main collection net;

[0004] The above patent can resist the impact of rolling stones to a certain extent, but in actual use, there are too many setting points of the nozzles, and the direction is directly toward the falling point of the rolling stones. Too many setting points of the nozzles and the direction are too concentrated, which means that the installation and maintenance costs increase, and it will also lead to uneven effect of the high-pressure water curtain. At the same time, it reduces the water curtain pressure of a single nozzle, and the requirements for the external water pump are too high, which reduces the overall effectiveness of the protective device. The overall cost is high. It is necessary to improve the existing technology. To this end, we propose a rolling stone blocking protective device for layer slope blasting to solve the above problems.

[0034] How it works

[0035] Solid infrastructure:

[0036] A cable net 2 is provided at the bottom of the ramp 1, and the cable net 2 is tightly combined with the ramp 1 through a fixed connection. This structure ensures the stability and firmness of the device on the slope.

[0037] The side of the cable net 2 close to the ramp 1 is connected to the ramp 1 through the cable 201, and the end away from the cable net 2 is also fixedly connected to the ramp 1, forming a triangular stable structure.

[0038] Triangular structure distribution:

[0039] The support plate 3 is arranged at the bottom of the ramp 1 and is fixedly connected to the ramp 1 through the support rollers 301, also forming a triangular structure. This layout not only enhances the overall stability, but also helps to disperse and absorb the impact force of rolling stones from the slope.

[0040] PU water bag protection:

[0041] A protective component 4 is provided between the cable net 2 and the support plate 3, mainly comprising a PU water bag 401. The PU water bag 401 contacts the cable net 2 on one side and the support plate 3 on the other side, and the bottom is fixedly connected to the ramp 1 through a connecting pipe 402. The elastic support of the PU water bag can effectively reduce the impact force of rolling stones, thereby protecting the safety of the working area.

[0042] The function of the injection device:

[0043] The device also includes a complex spraying device, in which the spraying tube 408 changes the spraying direction by adjusting the angle to generate a strong water curtain, effectively preventing the movement of the rolling stone. The surface of the spraying tube 408 is provided with multiple spraying windows 410, and after spraying, the spraying windows are completely closed by the plug seat 415 to prevent foreign matter from entering, thereby ensuring the long-term effectiveness and safety of the device.

[0044] Structural optimization and cost control:

[0045] The device design takes cost and adaptability into consideration and adopts a single spray device. Compared with the traditional multi-nozzle method, it is not only less expensive but also easier to adjust and maintain. Through the combination of the above multiple protection measures, this device effectively protects the working area from the harm of stone rolling impact and improves work safety and efficiency.
