The present invention relates to a shock absorber 600 , and specifically, the shock absorber 600 is to reduce an impact acting on the second wire 220 , and has a restoring force due to elasticity. As the shock absorber 600 is formed in a zigzag, the fastening part 610 to which the wire rope 200 formed in an oblique line is fastened is formed, and the fastening part 610 is the fastening roller 620 to which the wire rope 200 is in contact. ) and an extension body 630 for fixing the fastening roller 620 is formed. And the shock absorber 600 has an elastic part 640 that applies elasticity to the fastening part 610 is formed, and the elastic part 640 includes an elastic case 642 and an elastic case ( An elastic plate 643 is formed on the front surface of the 642 to prevent separation of the elastic body 641 . The fastening roller 620 is the wire rope 200 is in contact, and when an impact is applied to the wire rope 200 by a rockfall or tensioning the wire rope 200, the fastening roller 620 by the wire rope 200 is rotate And the fastening roller 620 is fixed by the extension body 630, and bolts and nuts are fastened to the extension body 630, so that the fastening roller 620 can be detached. This is for fastening the wire rope 200 to the fastening part 610 , and after coupling the wire rope 200 to the extension body 630 , the fastening roller 620 may be coupled.

And the extension body 630 is formed with fastening plates 631 formed above and below the fastening roller 620 , and the plurality of fastening plates 631 are formed so that one end is connected to each other. In addition, the fastening plate 631 is formed to be narrower in width toward the fastening roller 620 , which is to disperse the load applied by the wire rope 200 toward the elastic part 640 . In addition, the fastening plate 631 is formed to be narrower in width toward the fastening roller 620 , which is to disperse the load applied by the wire rope 200 toward the elastic part 640 . In addition, in another embodiment, the extension body 630 is formed with a rotating body that rotates between the plurality of fastening plates 631 by elasticity. The rotating body rotates inside when the wire rope 200 is inserted into the extension body 630 and returns to the original state after the wire rope 200 is inserted to prevent the wire rope 200 from being separated from the extension body 630. At the same time to be fastened to the fastening roller (620). Accordingly, it is possible to increase the construction efficiency by simply coupling the wire rope 200 to the extension body 630 .

And the fastening plate 631 is rotated at the end of the elastic part 640 by rotating the fastening roller 620 according to the angle at which the wire rope 200 is fastened to the fastening roller 620, thereby fixing the wire rope 200 and fixing it. It is possible to reduce the stress load acting on the device 300 and at the same time prevent the twisting phenomenon of the wire rope 200 .

(Example 5-6) In Example 5-4, the rock fall prevention net fixture of the present invention includes: an elastic shaft 644 formed on the elastic part 640 and fastened to an end of the fastening part 610; an elastic body 641 surrounding the elastic shaft 644 and buffering the pressure of the wire rope 200; an elastic case (642) formed outside the elastic body (641) and through which the elastic shaft (644) passes; and an elastic plate 643 coupled to the end of the elastic shaft 644 and moving by the elastic shaft 644 in the elastic case 642 .

The present invention relates to the elastic part 640, and specifically, when an impact is applied to the wire rope 200, elasticity is provided. The elastic part 640 is formed with an elastic case 642 accommodating the elastic body 641 and the fastening shaft 631 , and the elastic case 642 is formed in a cross section of various shapes such as a square or a circle. This prevents foreign substances such as falling rocks and tree branches formed therein from flowing into the elastic body 641 to reduce the buffering effect. In general, the rockfall prevention net 100 and the fixing device 300 are exposed to the outside, so that foreign substances are introduced into the elastic body 641 and there is a problem that the wire rope 200 cannot be buffered when a rockfall occurs. However, the elastic case 642 of the present invention is formed to surround the elastic body 641 to prevent foreign substances from flowing into the elastic body 641 .

In addition, an elastic plate 643 is formed on one surface of the elastic case 642 , and an elastic hole through which the elastic shaft 644 passes so that the fastening plate 631 is coupled to the end is formed on the other surface. And the elastic shaft 644 is formed to pass through the elastic case 642, a fastening plate 631 is formed at one end, and the elastic plate 643 is coupled to the other end. And the elastic body 641 is formed so as to surround the elastic shaft 644 inside the elastic case 642. When an impact and pressure are applied to the wire rope 200, the fastening part 610 pushes the elastic part 640 to the outside. move it At this time, as the gap between the elastic body 641 is narrowed by the elastic plate 643 and then widened by the elasticity, the fastening part 610 returns to the elastic part 640 direction. In this way, the fixing device 300 is formed with an elastic part 640 in order to relieve the pressure and shock acting on the wire rope 200, and according to the wire rope 200 in order to reduce the stress load of the wire rope 200. It is possible to rotate the position of the fastening roller 620 to which the wire rope 200 is fastened while rotating along the X axis, the Y axis, and the Z axis.

Therefore, the shock absorber 600 reduces the pressure and impact acting on the wire rope 200, and has a variable characteristic according to the position of the wire rope 200 in order to improve the durability of the wire rope 200.
