Description

Technical Field

[0001] The utility model relates to the technical field of blasting, in particular to a rubber net for preventing flying stones for blasting. Background Art

[0002] In blasting engineering, flying rocks are a common risk factor, which may cause serious damage and losses to surrounding personnel, equipment and buildings. In order to reduce the harm of flying rocks, people usually adopt various protective measures, such as setting up protective walls and using protective nets. However, traditional protective nets are usually woven from metal wires. Although they have a certain protective effect, they are heavy, inconvenient to install and disassemble, and easily corroded and damaged. In addition, traditional methods for preventing flying rocks mainly include setting up protective barriers, using sandbags or other materials for covering, etc., and the existing rubber stone nets are directly covered on the blasting port when in use, and then the sandbags are pressed against the rubber stone nets. Although these methods can play a protective role to a certain extent, there are some shortcomings. For example, the setting of protective barriers may affect the operating efficiency, and the protective effect of materials such as sandbags is limited, and they are easy to break when the blasting impact force is large, and cannot play a good protective role. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem solved by the utility model is to provide a flying stone-proof rubber net for blasting, so as to solve the problem that the existing rubber net is easily broken by flying stones during blasting operations and thus cannot effectively play a protective role.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a rubber net for preventing flying stones for blasting, characterized in that: it includes a frame, a connecting groove is provided on the frame, a protective layer is provided in the connecting groove and is matched and connected with the frame; the protective layer includes a protective mesh body, a buffer layer, and a support plate, a plurality of buffer layers are provided at the upper end of the protective mesh body, a support plate is provided at the upper end of the buffer layer, and the protective mesh body, the buffer layer, the support plate and the frame are all connected in a sliding manner through the connecting groove; the protective mesh body, the buffer layer and the support plate are arranged in sequence from bottom to top; a fixing piece is provided on one side of the frame and is detachably connected to the frame.

[0005] The beneficial effects of this solution are as follows: the flying rocks caused by blasting can be blocked by the rubber net and the multi-layer buffer layer, the design of the buffer layer can absorb the impact force of the flying rocks, and the support plate provides additional support, thereby increasing the stability of the entire rubber net; the connecting groove on the frame enables the protective layer to be slidably connected to the frame, which is convenient for installation and disassembly, thereby improving construction efficiency; the fixing parts on one side of the frame can be detachably connected, thereby ensuring that the rubber net is easy to install and maintain when being replaced, and has good fixity during use.

[0006] Furthermore, a fixing groove is provided on the frame, and the fixing groove is cooperated with the connecting piece fixedly provided on the fixing piece. In different blasting operations, only damaged parts need to be replaced or the connection position needs to be adjusted, thereby reducing material waste and cost expenditure. The cooperative connection between the fixing groove and the connecting piece can make the rubber net more stable as a whole and avoid shaking or deformation during use, which helps to improve the protective performance and ensure the safety of personnel and the surrounding environment.

[0007] Furthermore, the connecting groove is arranged in a U-shaped structure, and the two sides of the U-shaped structure can provide additional blocking and restriction to prevent the protective layer from slipping in the connecting groove. At the same time, the U-shaped structure of the connecting groove allows the protective layer to slide easily in the groove, which is convenient for installation and adjustment of position. During the installation process, the protective layer can be more easily aligned and inserted into the connecting groove, thereby improving the efficiency and accuracy of the installation.

[0008] Furthermore, limit members are provided on both sides of the frame, which are cooperated and connected with the limit holes provided on the connecting member. The limit members can limit the movement range of the connecting member on the frame to prevent the connecting member from excessive sliding or swinging, which helps to maintain the stable position of the protective layer.

[0009] Furthermore, the protective net body is a stone rubber net, which has a porous structure. The stone rubber net is usually made of polymer material and has a lower density, so it is relatively light, which makes installation and transportation more convenient and reduces physical labor during the construction process. When sound waves pass through the porous structure of the stone rubber net, scattering and attenuation will occur, thereby reducing noise propagation.

[0010] Furthermore, the buffer layer is composed of two pieces, which are arranged in a close relationship. The buffer layer is made of rubber material. The two buffer layers are bonded together to form a thicker buffer area, which can better absorb and disperse the impact force. The rubber material has high elasticity and flexibility, and can effectively reduce the energy transfer when objects collide.

[0011] Furthermore, the buffer layer is arranged as a porous structure, and the through holes arranged on the buffer layer are arranged in a cross-staggered manner with the through holes on the protective net body. The cross-arranged through holes can disperse the force more evenly when impacted. When external force acts on the buffer layer, the cross structure between the through holes can better absorb and disperse the energy, providing a more effective buffering effect.

[0012] Furthermore, a buffer pad is arranged between the support plate, the protective net body and the buffer plate, which can absorb and disperse the impact force from the outside and reduce the direct collision between the support plate, the protective net body and the buffer plate, which helps to reduce the vibration and noise of the structure and extend the service life.

The frame 1 is arranged in a U-shaped structure. Both sides of the frame 1 with the U-shaped structure can provide additional blocking and restriction on the protective layer to prevent the protective layer 13 from slipping in the connecting groove 12. At the same time, the U-shaped structure of the connecting groove 12 allows the protective layer 13 to slide easily in the connecting groove 12, which is convenient for installation and position adjustment. During the installation process, the protective layer 13 can be more easily aligned and inserted into the connecting groove 12, which improves the efficiency and accuracy of the installation. The protective layer 13 includes a protective net body 8, a buffer layer 9, and a support plate 10. The protective net body 8 is a stone rubber The protective net body 8 is a porous structure. Since the stone rubber net is usually made of polymer material and has a low density, it is relatively light in weight, which makes installation and transportation more convenient and reduces physical labor during construction. When sound waves pass through the porous structure of the stone rubber net, scattering and attenuation will occur, thereby reducing noise propagation; the buffer layer 9 arranged at the upper end of the protective net body 8 is two pieces, and the buffer layer 9 is fitted together. The buffer layer 9 is a buffer layer 9 made of rubber material. The two buffer layers 9 are fitted together to form a thicker buffer area, which can better absorb and disperse the impact force. A buffer pad 11 is arranged between the buffer layer 9 and the protective net body 8. Similarly, a buffer pad 11 is also arranged between the support plate 10 and the buffer layer 9. A buffer pad 11 is provided, which can absorb and disperse the impact force from the outside, reduce the direct collision between the support plate 10, the protective net body 8 and the buffer layer 9; the buffer layer 9 is set as a porous structure, and the through holes set on the buffer layer 9 are staggered and arranged crosswise with the through holes on the protective net body 8. The cross-arranged through holes can disperse the force more evenly when impacted.

When in use, sandbags can be placed on the support plate 10 to load the entire equipment, so as to avoid the stone rubber net being shaken away during blasting. A fixing groove 3 is provided on the frame 1, and the fixing groove 3 is connected with the connecting piece 4 fixedly provided on the fixing piece 2. The frame 1 and the fixing part 2 are disassembled and linked. In different blasting operations, only damaged parts need to be replaced or the connection position needs to be adjusted, which reduces material waste and cost expenditure. The coordinated connection between the fixing groove 3 and the connecting part 4 can make the rubber net more stable as a whole and avoid shaking or deformation during use, which helps to improve the protection performance and ensure the safety of personnel and the surrounding environment. Limiting members 6 are arranged on both sides of the frame 1. The limiting members 6 are coordinated and connected with the limiting holes 5 arranged on the connecting part 4. The limiting members 6 can limit the movement range of the connecting part 4 on the frame 1 to prevent the connecting part 4 from excessive sliding or swinging, which helps to maintain the position of the protective layer stable. A plurality of grooves 7 are arranged at the lower end of the frame 1 to facilitate the arrangement of the detonation guide line.

[0018] Specific implementation method: install the explosive in the blasting hole, and guide the detonation guide line from the blasting hole to the safe detonation position, place the frame 1 just above the blasting hole, set the protective net 8 at the bottom layer, then install the buffer layer 9 and the support plate 10 in sequence, finally connect the fixing part 2 to the frame 1 through the connecting part 4 and the fixing groove 3, and then fix them by the limiter 6, finally place sandbags and other heavy objects on the support plate 10 to fix the frame 1, when in use, flying stones are blocked by the stone rubber net, the buffer layer 9 and the support plate 10, and better protection is obtained. At the same time, the sandbags set on the support plate 10 can also provide better protection to avoid being penetrated by stones.
