BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber for a conveying-material blocking fence having a tubular shock absorber and a conveying obstruction fence having the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber for a flow blocking fence and a flow-blocking fence having the same. More particularly, the present invention relates to a shock absorber for a conveying obstacle fence having a small risk of being deformed or damaged by a continuous load accumulation, .

In the case of small rivers located in mountainous areas, there are many cases where flood damage is caused in the upstream part of the bridge due to the damages of bridges or damages of the bridge due to the decrease of traffic capacity.

The main route of occurrence is the occurrence of driftwood and debris flow from landslide to landslide during heavy rainfall. Passage occur most often when the high water level lasts for a long time due to large floods, where the resulting influx is transported separately, generally tending to move to the center of the stream, .

Conventional rockfall-blocking fences can be used to block the transfer of conveyed objects. A conventional rockfall-blocking fence has a structure in which a plurality of pillars are embedded and fixed through a concrete foundation on the ground, and wire ropes are connected in a horizontal direction between the pillars. At this time, in order to mitigate the impact applied to the wire rope by falling rocks and prevent deformation or breakage of the fence, a connecting member is provided in the middle of the wire rope to distribute the load around the connecting member.

However, in the conventional fence, there is a risk that the connecting member is deformed or broken due to the continuous accumulation of the load, and when the connecting member is broken, there is a danger that the wire rope is loosened and the accumulated traveling goods are transported. In addition, when the connecting member is fixed by applying tension to the wire rope once, it is difficult to partially replace the connecting member, which is problematic in terms of maintenance.

Further, in the conventional fence, an elastic member such as a buffer spring is installed to buffer the tension transmitted to the connecting member while an external force is applied to the wire rope extending to the plurality of struts around the connecting member. However, such a buffer spring has a problem that it is difficult to process and the cost is high.

It is an object of the present invention to provide a shock absorber for a conveying object blocking fence which is designed to solve the above-described problems of the prior art, and which is less susceptible to deformation and breakage, is easy to process, and can be implemented at low cost.

Another object of the present invention is to provide a flow blocking fence that is less susceptible to deformation and breakage, is easy to process, and can be implemented at low cost.

In order to achieve the above object, according to the present invention, there is provided a shock absorbing device for use in a fence for shutting off the conveyance of a conveyed object, comprising: a cylindrical buffer member having a plurality of insertion holes formed on both sides thereof; A fixing member coupled to the end of the pair of wire ropes passing through the insertion hole formed on the other side via the inside of the buffer member; And a wedge member inserted between the ball and the wire rope and having a radius of curvature of one end and a radius of curvature of the other end.

Preferably, there is a relationship of t1 < t2 between a thickness t1 of an end portion having a small radius of curvature in the wedge member and a thickness t2 of an end portion having a large radius of curvature.

Preferably, the buffer member includes a wrinkle portion that buffers the external force when the buffer member is deformed by an external force applied to the wire rope.

The present invention also provides a fence for blocking the conveyance of a conveyed object, comprising: a tubular buffer member having a plurality of insertion holes formed on both sides thereof; and an insertion hole formed in one side surface of the buffer member and passing through the inside of the buffer member A pair of wire ropes passing through the insertion hole formed on the other side of the wire rope; a fixing member coupled to a terminal end portion of the wire rope; and an insertion hole and a wire rope close to the fixing member, And a wedge member inserted at one end and a radius of curvature at the other end.

FIG. 3A is a vertical sectional view of one end of the wedge member 150 shown in FIG. 2, and FIG. 3B is a vertical sectional view of the other end of the wedge member 150 shown in FIG.

1 to 3, a shock absorber 100 for a flow blocking fence according to the present embodiment includes wire ropes 110 and 130, a buffer member 120, a wedge member 150, and a fixing member 170.

)을 갖고, 쐐기부재(150)의 타단(153)은 일단(151)으로부터 연장되어 제2 곡률반경(

)를 갖는다. 제1 곡률반경(

)과 제2 곡률반경(

)은 수학식 1과 같은 관계를 갖는다.The wire ropes 110 and 130 may be connected to the fixing member 170 at one side and the strut may extend through the buffer member 120 at the other side and may be connected to a support provided on the floor through a concrete foundation. The cushioning member 120 is formed in a cylindrical shape like a cylindrical shape, and an insertion hole is formed on both sides of the cushioning member 120 so that the wire ropes 110 and 130 pass through the insertion hole. The wedge member 150 may include one end 151 and the other end 153 of the wedge member as shown in Figures 2 to 3B and may have one end 151 and the other end 153 of the wedge member 150, The radius of curvature is different. One end 151 of wedge member 150 has a first radius of curvature

, And the other end 153 of the wedge member 150 extends from one end 151 and has a second radius of curvature

). The first radius of curvature (

) And the second radius of curvature (

) Has a relationship as shown in Equation (1).

The thickness of the valley in the vertical section of the one end 151 is t1 and the thickness of the valley in the vertical section of the other end 153 is t2. The thickness of one end and the thickness of the other end have the relationship as shown in the following equation (2).

The fixing member 170 engages with the wire ropes 110 and 130 protruding through the buffer member 120 to fix the wire ropes 110 and 130.

Each of the wire ropes 110 and 130 is provided through the insertion hole formed in the cushioning member 120 and a part of the wire ropes 110 and 130 protruded through the cushioning member 120 And is fixedly coupled with a fixing member 170 provided on one side of the buffer member 120. [ Meanwhile, when the wire ropes 110 and 130 are inserted and inserted into the insertion holes formed in the cushioning member 120, an interval between the insertion holes and the wire ropes 110 and 130 occurs. For the sake of explanation, the distance between the insertion holes and the wire ropes 110 and 130 is d1 Quot; One end 151 of the wedge member 150 is inserted into the gap d1 and the other end 153 of the wedge member 150 is in contact with the fixing member 170. [ At least one wedge member 150 may be inserted when the wedge member 150 is inserted in the interval of d1. For example, one end of the two wedge members may be inserted and the other end 153 of the wedge member may be inserted into the buffer member 120 may be evenly contacted. Also, t1 and t2 and d1 of the wedge member 150 preferably have the relationship shown in Equation (3).

An external force is applied to the wire ropes 110 and 130 to distribute the tension transmitted by the wire ropes 110 and 130 more stably than when the wedge member 150 is inserted into the insertion hole formed in the cushioning member 120 So that breakage of the fixing member 170 can be prevented.

As for the effects of each of the above-described components and the bonding, external forces act on the opposite sides of the respective wire ropes by falling stone or the like. That is, one wire rope 110 is pulled to the left and tension is applied and the other wire rope 130 is pulled to the right and tension is applied. Therefore, the wire ropes 110 and 130 fixed at one side by the fixing member 170 are subjected to continuous tension. The buffer member 120 is provided to prevent the fixing member 170 from being damaged as the load is accumulated and the insertion hole formed in the buffer member 120 is larger than the wire ropes 110 and 130, So that the fixing member 170 is caught by the end of the buffer member 120 to disperse the external force applied to the fixing member 170. The wedge member 150 is inserted into the gap d1 between the insertion hole formed in the buffer member 120 and the wire ropes 110 and 130 to disperse the external force applied to the fixing member 170. [

The external force applied to the wire ropes 110 and 130 by the wedge member 150 is transmitted to the cushioning member 120 and the wedge member 150 in advance to prevent the fixing member 170 from being damaged. In addition, the fixing member 170 is connected in various ways for firm connection with one side of the wire ropes 110 and 130, so that it is not easy to replace or repair it in the event of breakage. However, in the presence of the wedge member 150, When the wedge member 150 is first broken by the load accumulation, the user can easily insert the new wedge member 150 by removing the wedge member 150 from the insertion hole formed in the buffer member 120. In addition, when load is concentrated intensively on the fixing member 170, the wire ropes 110 and 130, etc. in consideration of the risk of rockfall or the amount of rockfall, at least one wedge member 170 is inserted and transmitted by the wire ropes 110 and 130 It is possible to more effectively disperse the external force.

FIG. 4 is a view showing a shock absorber 200 for a conveying object blocking fence according to another embodiment of the present invention.

Referring to FIG. 4 and to avoid redundant description, the buffer device 200 for blocking a flow-blocking fence according to the present embodiment has at least one wrinkle portion 221 formed in the buffer member 220. The corrugated portion 221 can absorb the external force more effectively than when the external force is transmitted to the buffer member 220 by the wire ropes 210 and 230. On the other hand, the wrinkles 221 of the present embodiment may not be limited in position, shape or the like by the drawings.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. something to do.
