Wire clamping apparatus for Falling rock prevention fence

The present invention relates to a cushioning wire fixing device for rockfall prevention measures, and more particularly to a buffering wire fixing device for rockfall prevention measures that can mitigate external impact on the wire rope.

Generally, rockfall prevention measures are installed to protect vehicles and pedestrians from falling rocks falling from slopes such as mountains and hills on the side of the road.

1 is an exemplary view showing a conventional rockfall prevention measures.

As shown in FIG. 1, the rockfall prevention measure is composed of a plurality of struts 10 and a plurality of wire ropes W provided through the struts 10 provided at regular intervals, and the wire rope W is a strut 10. A plurality are installed at regular intervals along the height direction.

Then, when the rock or soil is dropped in the fall prevention measures, the wire rope (W) is caught, the wire rope (W) is tensioned to mitigate the impact of the stone or soil.

However, the conventional rockfall prevention measures have the following problems.

First, there is a problem in that the wire rope is easily broken when the impact force applied to the wire rope is greater than the tension or shear force of the wire rope because a shock absorber is not provided when the wire rope is impacted by stones or soil. .

Second, the wire rope has difficulty in maintaining a constant tension because the degree of tension varies depending on the season.

Here, there is a problem in that maintenance costs are generated as the tension or relaxation work is performed so that the wire rope maintains a constant tension every season.

Thus, research and development has been made on a buffer type rockfall prevention measures that can alleviate the external impact on the wire rope.

In order to solve the problems as described above, an object of the present invention is to provide a shock-absorbing wire fixing device for rockfall prevention to be made to mitigate the external impact on the wire rope and to maintain a constant tension on the wire rope.

In order to achieve the above object, the present invention is coupled to the support rod, one end is inserted into a plurality of insertion holes formed in the fall prevention pillar, the support rod is prevented from being separated from the fall prevention pillar A separation prevention bolt to be inserted, and installed at the other end of the support rod, the connecting cylinder slidable with respect to the support rod, the pressing member is passed through the support rod and coupled to one side of the connection cylinder, the support rod and Is coupled to the support member for guiding the movement of the connecting cylinder, one side is supported by the pressing member and the other side is supported by the support member to provide a restoring force for the movement of the connection cylinder, the other side of the connection cylinder A wire fixing member for engaging and fixing the wire rope and the separation Provided between the prevention bolt and the rockfall prevention column portion is a cushioning wire fixing device for the rockfall prevention measures comprising a close contact member having a larger outer diameter than the separation prevention bolt.

In addition, the pressing member has a third screw thread formed on an outer circumference thereof, and a fourth thread thread and a fifth thread thread are formed on inner surfaces of both ends of the connection cylinder, and the fourth thread thread is coupled to the third thread thread. The thread is characterized in that coupled with the wire fixing member.

On the other hand, a guide groove is formed on the inner surface of the connection cylinder and a guide protrusion corresponding to the guide groove is formed on the outer periphery of the support member so that the guide groove of the connection cylinder is moved along the guide protrusion. .

Here, the contact member is formed between the separation prevention bolt and the falling-rock prevention pillar portion is formed with an outer diameter larger than the separation prevention bolt.
