Description

Technical Field

[0001] This utility model relates to the field of mine safety, and in particular to a safety protection net device for flying rocks during blasting in quarries. Background Technology

[0002] During blasting operations in quarries, protective devices are needed to reduce the damage of flying rocks to the surrounding environment and to protect surrounding equipment and personnel. Traditional protective nets are mostly made of wire mesh or nylon mesh, which are not strong enough and are easily damaged when faced with high-speed flying rocks, resulting in low interception efficiency. The existing protective nets have a simple structure, and the impact force of flying rocks directly acts on the supporting structure after impact, which can easily cause the supporting columns to tilt and collapse. This not only reduces the service life of the protective nets but may also cause secondary injuries. Large quarries have a wide blasting area, and the installation of traditional protective nets requires a lot of manpower and time. Moreover, they are difficult to reuse after dismantling, which reduces economic efficiency. Therefore, a safety protective net device for flying rocks in quarry blasting is designed.

[0003] The purpose of this utility model is to provide a safety net device for protecting against flying rocks during blasting in quarries, so as to solve the above-mentioned technical problems. To achieve the above purpose, this utility model adopts the following technical solution:

[0004] A safety net device for preventing flying rocks during blasting in a quarry includes a composite protective net and protective net mounting posts. Several sets of protective net mounting posts are arranged and fixedly installed. The two ends of the composite protective net are hung and fixed to the sides of the protective net mounting posts.

[0005] Based on the above technical solution, the composite protective net is composed of high-strength polyethylene fiber woven net, elastic rubber buffer net, steel wire mesh, post hooks, reinforcing steel cables, and hoisting hooks. The high-strength polyethylene fiber woven net, elastic rubber buffer net, and steel wire mesh are stacked and fixed in three layers. Hoisting hooks are arranged and fixed at equal intervals on the bottom edge of the reinforcing steel cables.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] A safety net device for protecting flying rocks during blasting in a quarry includes a composite protective net 1 and protective net mounting posts 2. Several sets of protective net mounting posts 2 are arranged and fixedly installed. The two ends of the composite protective net 1 are hung and fixed on the sides of the protective net mounting posts 2.

[0016] The composite protective net 1 is composed of a high-strength polyethylene fiber woven net 3, an elastic rubber buffer net 4, a steel wire mesh 5, a post hook 6, a reinforcing steel cable 7, and a lifting hook 8. The high-strength polyethylene fiber woven net 3, the elastic rubber buffer net 4, and the steel wire mesh 5 are stacked and fixed in three layers. The bottom edge of the reinforcing steel cable 7 is fixed with lifting hooks 8 at equal intervals. The lifting hooks 8 are hung on the top side of the high-strength polyethylene fiber woven net 3, the elastic rubber buffer net 4, and the steel wire mesh 5. The post hooks 6 are set on the side of both ends of the high-strength polyethylene fiber woven net 3, the elastic rubber buffer net 4, and the steel wire mesh 5 and on both ends of the reinforcing steel cable 7. The post hooks 6 are hung on the side of the protective net installation post 2.

[0017] The protective netting installation post 2 consists of an underground rod 9, a ground cylinder post 10, a side support leg 11, and a ground fixing foot 12. The underground rod 9 is inserted into the ground cylinder post 10. The side support leg 11 is sleeved and fixed on the outer side of the middle end of the ground cylinder post 10. The ground fixing foot 12 is sleeved and fixed on the outer side of the lower section of the ground cylinder post 10. The post hook 6 is hung on the side of the ground cylinder post 10.

[0018] The outer side of the ground column 10 is provided with a protective net hanging ring 13. The lower section of the ground column 10 is provided with fixing screw holes 14 at equal heights. The side support leg 11 is composed of an inclined support leg 15 and a column assembly 16. The inclined support leg 15 is connected to both sides of the column assembly 16 by opposing pivots. The column assembly 16 is fitted on the outer side of the middle section of the ground column 10. The ground fixing foot 12 is composed of a column collar 17 and a ground fixing plate 18. The ground fixing plate 18 is set at equal circumferential angles on the outer side of the column collar 17. The column collar 17 is fitted on the outer side of the lower section of the ground column 10 and is fixed to the outside of the fixing screw hole 14 by fixing bolts 19. The column hook 6 is correspondingly hung on the protective net hanging ring 13.

[0019] The working principle of this utility model is as follows: This structure has stronger protective capabilities, the material structure extends the service life, and the structural design allows for quick installation and disassembly.

[0020] In the structure, the high-strength polyethylene fiber woven mesh 3, the elastic rubber buffer mesh 4, and the steel wire mesh 5 adopt a three-layer composite reinforced protective net, which can have a stronger protective capability. At the initial design stage, a protective net with a smaller aperture can be designed according to the usage conditions and interception conditions, which can also enhance the range of protective capabilities.

[0021] The three-layer composite net uses materials that have both rigidity and flexibility, and is reinforced with steel cables 7 on the upper side. This reduces the deformation of the protective net during long-term use. In addition, the protective net mounting posts 2 adopt a modular structural design, which can be replaced according to the damaged parts during maintenance, thus extending the overall service life.

[0022] During installation and deployment, after digging holes in the ground, the ground-penetrating rod 9 is first embedded into the ground. Then, according to certain needs, a portion of the ground cylinder column 10 is pre-buried so that the lower end of the ground cylinder column 10 is also buried underground. The ground fixing feet 12 are then fixed to the ground to ensure the stability of the ground cylinder column 10. After the composite protective net 1 is hung, the side support legs 11 are installed in the corresponding positions as needed. For example, side support legs 11 need to be set at the corners of multi-segment protective nets where the force is greater than that of the plane.

[0023] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
