It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

First, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a state in which the opening and closing device of the central separator according to the present invention is disposed between the structure of the central separator and the tunnel.

Referring to FIG. 1, a central separator 30 may be installed at the center line of the road 10 to prevent the vehicle from invading into the opposite lane. The road 10 may be connected to the tunnel 20. The structure 40 may be disposed at one side or both sides of the tunnel 20 to separate both lanes. The structure 40 may include a landscape object such as earth and sand in which trees and the like are planted, and guide rails disposed along the circumference of the landscape object. Such a structure 40 may be connected to the median (30).

An emergency u-turn section 50 may be disposed to allow a U-turn of an isolated vehicle or a special vehicle in an emergency situation of the tunnel 20 or the road 10. For example, the emergency u-turn section 50 may be disposed near the tunnel 20. The emergency u-turn section 50 may have a sufficient width so that the isolated vehicle or the special vehicle can u-turn.

The emergency u-turn section 50 may be provided with an opening and closing device 100 of the central separator. The opening and closing device 100 of the central separator opens an emergency u-turn section 50 when an emergency occurs so that an isolated vehicle or a special vehicle can u-turn to the opposite lane.

The opening and closing device 100 of the central separator may be installed in a case structure that rotates around the post 110.

2 is a plan view showing the opening and closing device of the central separator, Figure 3 is a side view showing the opening and closing device of the central separator.

2 and 3, the opening and closing device 100 of the central separator may include a post 110, a folding separator 120, and a plurality of wheels 150.

The posts 110 may be disposed at both sides of the emergency u-turn section 50 of the central separator 30, respectively. One post 110 may be disposed on the side of the structure 40 near the tunnel 20, and the other post 110 may be disposed on the middle separator 30 side. The post 110 may be fixed to the road 10 to be parallel to the center line on the road 10.

The folding separator 120 may be rotatably coupled to each post 110 to open and close the emergency u-turn section 50. At this time, the pair of folding separator 120 may be disposed in succession to the emergency u-turn section 50 to close the emergency u-turn section (50). Therefore, as compared with one folding separator 120, the length of each folding separator 120 can be reduced to prevent the folding separator 120 from being deformed or damaged. In addition, even if the length of each folding separator 120 can be secured long enough to open the length of the emergency u-turn section 50, the length of the emergency u-turn section 50 can be secured enough to make a large vehicle U-turn Can be.

The folding separator 120 may be formed to be collapsible to open close to the central separator 30 or the surrounding structure 40. Therefore, even when the width of the central separator 30 or the width of the surrounding structure 40 is wide, as the folding separator 120 is folded or folded, it does not interfere with the central separator 30 or the surrounding structure 40. You may not. Thus, the folding separator may be opened close to the median 30 or the surrounding structure 40 regardless of the shape of the median 30 or the surrounding structure 40.

The plurality of wheels 150 may be coupled to the lower portion of the folding separator 120 to support the folding separator 120. The plurality of wheels 150 may prevent the folding separator 120 from sagging down.

4 is an enlarged view illustrating a connection structure of the switchgear, FIGS. 5 and 6 are exploded views illustrating a connection structure of the switchgear, and FIG. 7 is an enlarged view illustrating a coupling part of the switchgear.

4 to 7, the fold separator 120 may include a rotary slider 121, a rotation angle adjuster 123, a hinge 130, and a U-turn section separator 125.

The rotary slider 121 may be rotatably coupled to the post 110. For example, the rotary slider 121 may be formed in a cylindrical shape so that the cylindrical post 110 is inserted. Support jaw 115 may be formed on the outer surface of the post 110 to support the lower portion of the rotary slider 121. The support jaw 115 may be formed in an annular flange shape so as to contact the entire lower end of the rotary slider 121. The rotation slider 121 may be formed in various structures as long as the rotation slider 121 is rotatably coupled to the post 110.

The rotation angle adjuster 123 may be coupled to the rotation slider 121. The rotation angle adjuster 123 may be formed in a rectangular frame shape or a ladder shape by connecting the horizontal member and the vertical member to each other. The horizontal member and the vertical member may be formed in the form of a steel pipe.

The length of the rotation angle adjuster 123 may be formed to have an appropriate length in consideration of the width of the central separator 30 or the shape of the surrounding structure 40. For example, when the width of the central separator 30 or the surrounding structure 40 is large, the length of the rotation angle adjuster 123 may be formed larger than the width of the central separator 30 or the surrounding structure 40. . At this time, the rotation angle adjuster 123 coupled to the post 110 on the central separator 30 side is formed longer than the width of the central separator 30, coupled to the post 110 on the peripheral structure 40 side Rotation angle adjuster 123 may be formed longer than the adjacent width of the surrounding structure (40). Therefore, when the folding separator 120 is rotated at the rotation angle adjuster 123 about the hinge 130, the rotation angle may not be limited by the central separator 30 or the surrounding structure 40. As a result, when the folding separator 120 is opened, the folding separator 120 may be prevented from interfering with the central separator 30 or the surrounding structure 40, so that the folding separator 120 may be completely opened.

Rotation angle adjuster 123 installed on one side post 110 and the rotation angle adjuster 123 installed on the other side post 110 may be formed in a different length (L1, L2). For example, when the width of the structure 40 and the width of the median separator 30 are different, the rotation angle adjuster 123 has a different length depending on the width of the structure 40 and the width of the median separator 30. It may be formed (L1, L2). In general, the width of the structure 40 is greater than the width of the center separator 30, the rotation angle adjuster 123 of the structure 40 side is formed longer than the rotation angle adjuster 123 of the center separator 30 side (L1 <L2).

The wheel 150 may be installed on the U-turn section separator 125 side of the rotation angle adjuster 123. The wheel 150 may prevent the U-turn section separator 125 side of the rotation angle adjuster 123 from sagging down. In addition, the wheel 150 may support the lower portion of the rotation angle adjuster 123 when the rotation angle adjuster 123 is rotated about the post 110.

The rotation angle adjuster 123 and the rotation slider 121 may be coupled via the coupling unit 140. The coupling part 140 may include a first fixing bracket 141, a connection bracket 145, and a second fixing bracket 147.

The first fixing bracket 141 may be fixed to the outer surface of the rotary slider 121. In this case, the first fixing bracket 141 may be in the form of a "c" panel formed vertically long along the longitudinal direction of the rotary slider 121. The bent portion of the first fixing bracket 141 may be fixed to the outer surface of the rotary slider 121 by welding or bolts.

At least two connection brackets 145 may be installed on the first fixing bracket 141. For example, the connection bracket 145 may be disposed above and below the first fixing bracket, respectively. The connection bracket 145 may be coupled to the first fixing bracket 141 by the first fixing bolt 142.

The connection bracket 145 may be formed in a rectangular cylinder shape as a whole. In this case, the connection bracket 145 may include a pair of unit brackets having a substantially "c" shape, and fastening bolts for fastening the pair of unit brackets while the openings of the unit brackets overlap each other. The connection bracket 145 may be formed in various forms.

The second fixing bracket 147 may be fixed to the post 110 side of the rotation angle adjuster 123. In this case, the pair of second fixing brackets 147 may correspond to the connection brackets 145, respectively. Each second fixing bracket 147 may be coupled to each connection bracket 145 by a second fixing bolt 148. The second fixing bracket 147 is formed in a substantially "c" shape and both sides of the bent may be fixed to the rotation angle adjuster 123 by welding or bolts.

The hinge 130 may be disposed between the rotation angle adjuster 123 and the folding separator 120. The hinge unit 130 may include a first hinge bracket 131, a second hinge bracket 132, and a hinge shaft 135.

Two or more first hinge brackets 131 may be fixed to the U-turn section separator 125 side of the rotation angle adjuster 123. For example, the first hinge bracket 131 may be fixed to the upper side and the lower side of the rotation angle adjuster 123, respectively. A first hinge hole 131a may be formed in the first hinge bracket 131 so that the hinge shaft 135 is inserted. In addition, first fixing holes 131b may be formed at both sides of the first hinge hole 131a in the first hinge bracket 131.

Two or more second hinge brackets 132 may be fixed to the U-turn section separator 125 to correspond to the first hinge bracket 131. For example, when two first hinge brackets 131 are installed, two second hinge brackets 132 may be installed. A second hinge hole 132a may be formed in the second hinge bracket 132 so that the hinge shaft 135 is inserted. In addition, second fixing holes 132b may be formed at both sides of the second hinge hole 132a in the second hinge bracket 132.

The hinge shaft 135 may be coupled to the first hinge bracket 131 and the second hinge bracket 132. For example, the hinge shaft 135 of the first hinge hole 131a of the first hinge bracket 131 and the second hinge hole 132a of the second hinge bracket 132 correspond to the first hinge hole. It may be inserted into the 131a and the second hinge hole 132a.

In addition, the fixing pin 137 is the first fixing hole 131b in a state where the first fixing hole 131b of the first hinge bracket 131 and the second fixing hole 132b of the second hinge bracket 132 correspond to each other. ) And the second fixing hole 132b. The fixing pin 137 may be fixed to both sides of the hinge shaft 135 to prevent the first hinge bracket 131 and the second hinge bracket 132 from being rotated about the hinge shaft 135. Therefore, the rotation angle adjuster 123 and the U-turn section separator 125 may be prevented from being bent around the hinge shaft 135.

U-turn section separator 125 is formed longer than the rotation angle adjuster 123, it may be coupled to the hinge portion 130. At this time, the U-turn section separator 125 may include a horizontal member disposed in parallel to the central separator 30, and a vertical member disposed at regular intervals in the horizontal member. The horizontal member and the vertical member may be formed of steel pipes. The U-turn section separator 125 may be formed in a ladder shape.

U-turn section separator 125 is formed to be significantly longer than the rotation angle adjuster 123, the U-turn section separator 125 is configured to substantially block or shield the emergency U-turn section (50).

The rotation angle adjuster 123 is configured to rotate in a state in which the U-turn section separator 125 is substantially separated from the post 110 by the length of the rotation angle adjuster 123. Therefore, since the rotation angle adjuster 123 prevents the U-turn section separator 125 from interfering with the central separator 30 or the surrounding structure 40 when the U-turn section separator 125 is rotated, the U-turn section separator 125 has a center separator 30. Or as close to the surrounding structure (40) as possible.

The plurality of wheels 150 may be coupled to the lower portion of the folding separator 120 to support the folding separator 120. The plurality of wheels 150 may allow the folding separator 120 to be smoothly rotated as the clouds contact the bottom surface.

The wheel 150 may be coupled to the lower portion of the rotation angle adjuster 123 and the lower portion of the U-turn section separator 125, respectively. For example, the wheel 150 may be installed at the lower side of the U-turn section separator 125 of the rotation angle adjuster 123. In addition, the wheel 150 may be installed at regular intervals below the U-turn section separator 125. As the length of the U-turn section separator 125 becomes longer, the number of installation of the wheels 150 may increase.

The wheel 150 may be elastically coupled to the lower portion of the rotation angle adjuster 123 and the lower portion of the U-turn section separator 125, respectively. Since the wheel 150 is elastically coupled with the rotation angle adjuster 123 and the U-turn section separator 125, even if the road surface of the road 10 is bumpy, the rotation angle adjuster 123 and the U-turn section separator 125 are stably provided. I can support it. Therefore, when the rotation angle adjuster 123 and the U-turn section separator 125 are rotated, the rotation angle adjuster 123 and the U-turn section separator 125 are prevented from being distorted or an imbalance moment is generated due to the unevenness of the road surface. Can be. Furthermore, since the rotation angle adjuster 123 and the U-turn section separator 125 can be prevented from being distorted or an imbalance moment is generated, the coupling portion that is a coupling portion of the rotation angle adjuster 123 and the U-turn section separator 125. It is possible to prevent the 140 and the hinge portion 130 from being damaged. Hereinafter, an example of the wheel 150 will be described.

The wheel 150 may include a lifting rod 151, an elastic member 155, and a wheel 157.

The lifting rod 151 may be reciprocally coupled to the lower portion of the rotation angle adjuster 123 and the U-turn section separator 125. The lifting rod 151 may be formed in a rod shape, and an insertion hole may be formed in the lower portion of the rotation angle controller 123 and the U-turn section separator 125 so that the lifting rod 151 is reciprocally inserted.

A flange portion 153 may be formed below the lifting rod 151. In addition, the lifting rod 151 may be movably coupled to the bushing 152. The bushing 152 may be fixed to the insertion hole (not shown) of the rotation angle adjuster 123 and the U-turn section separator 125.

The elastic member 155 may be coupled to the lifting rod 151 to elastically support the lower portion of the rotation angle adjuster 123 and the U-turn section separator 125. The lower portion of the elastic member 155 may be supported by the flange portion 153 of the elevating rod 151, and the upper portion of the elastic member 155 may be supported by the bushing 152.

The wheel 157 may be coupled to the lower portion of the elevating rod 151. At this time, the supporter 154 is formed in the lower portion of the lifting rod 151 to correspond to both sides of the wheel 157, the rotation axis of the wheel 157 may be coupled to the supporter 154.

The wheel 150 may further include a brake 159 to be rotatably installed on the rotation shaft of the wheel 157 to prevent the wheel 157 from rotating. The brake 159 may include a pressure lever 159a rotatably coupled to the rotation shaft of the wheel 157, and a friction lever 159b coupled to rotate with the pressure lever 159a to be in close contact with the wheel 157. Can be. The rotation of the wheel 157 may be prevented by the friction lever 159b contacting the wheel 157.

The operation of the opening and closing device of the central separator according to the present invention configured as described above will be described.

1 to 3, the opening and closing device of the central separator can normally partition the emergency U-turn section 50 on both sides. At this time, the pair of folding separator 120 is disposed parallel to the central separator (30). In addition, the fixing pin 137 is inserted into the first fixing hole 131b of the first hinge bracket 131 and the second fixing hole 132b of the second hinge bracket 132.

8 is a view showing a state bent when the opening and closing device of the central separator.

Referring to FIG. 8, when an emergency occurs in the tunnel 20 or the road 10, the opening / closing device of the central separator is opened so that a vehicle or a special vehicle isolated by earth and sand can turn to the opposite lane. At this time, as the two folding separators 120 are rotated about the corresponding post 110, the emergency u-turn section 50 is opened. Hereinafter will be described in order to rotate the center separator 30 side folding separator 120 and the structure 40 side folding separator 120 is rotated.

9 is a view illustrating a state in which the U-turn section separator is completely open toward the center separator side.

Referring to FIG. 9, the fixing pin 137 may be separated from the first fixing hole 131b of the first hinge bracket 131 and the second fixing hole 132b of the second hinge bracket 132. When pressing the U-turn section separator 125, the central separator 30 side folding separator 120 is rotated about the post (110). That is, the rotation angle adjuster 123 may be rotated about the post 110, and the U-turn section separator 125 may be rotated in a state bent with the rotation angle adjuster 123 by the hinge 130. . At this time, the rotation angle adjuster 123 so that the post 110 side of the U-turn section separator 125 is spaced apart by the post 110 and the rotation angle adjuster 123, the U-turn section separator 125 is the center separator ( It does not interfere with 30). Even when the width of the center separator 30 is wide, the U-turn section separator 125 is spaced apart from the post 110 so that it is not interfered by the center separator 30. Thus, the U-turn section separator 125 may be rotated to be as close as possible to the central separator 30.

If the rotation angle adjuster 123 and the U-turn section separator 125 are integrally formed without being folded or bent together, the opening and closing device may be interfered by the post 110 side of the center separator 30. In this case, the switchgear may be incompletely opened by the interference of the central separator 30. At this time, since the opening and closing device 10 is opened to maintain a constant angle with the central separator 30 (10), the opposite side of the post 110 of the opening and closing device is a considerable distance away from the central separator (30). As such, when the switchgear is incompletely opened, the vehicle may function as an obstacle when the vehicle makes a U-turn in the opposite lane. Alternatively, the emergency u-turn section 50 may be substantially narrowed.

10 is a view illustrating a state in which the U-turn section separator is completely open to the structure side.

Referring to FIG. 10, the fixing pin 137 may be separated from the first fixing hole 131b of the first hinge bracket 131 and the second fixing hole 132b of the second hinge bracket 132. When the U-turn section separator 125 is pressed, the structure 40 side folding separator 120 is rotated about the post 110. That is, the rotation angle adjuster 123 may be rotated about the post 110, and the U-turn section separator 125 may be rotated in a state bent with the rotation angle adjuster 123 by the hinge 130. . At this time, the rotation angle adjuster 123 is so that the post 110 side of the U-turn section separator 125 is spaced apart by the post 110 and the rotation angle adjuster 123, the U-turn section separator 125 is the structure 40 Does not interfere with). Even when the structure 40 is wide, the U-turn section separator 125 is spaced apart from the post 110 so that the structure 40 does not interfere with the structure 40. Thus, the U-turn section separator 125 may be rotated to be as close as possible to the structure 40.

If the rotation angle adjuster 123 and the U-turn section separator 125 are integrally formed without being folded or bent together, the opening and closing device may be interfered by the post 110 side of the structure 40. In this case, the switchgear may be incompletely opened by the interference of the structure 40. At this time, the opening and closing device is opened so as not close to the structure 40, the opposite side of the post 110 of the opening and closing device is remarkably far from the structure 40. As such, when the switchgear is incompletely opened, the switchgear may function as an obstacle when the vehicle makes a U-turn in the opposite lane. Alternatively, the emergency u-turn section 50 may be substantially narrowed.

As described above, the opening and closing device of the central separator is installed so that the rotation angle adjuster 123 is rotatable between the post 110 and the U-turn section separator 125, the U-turn section separator 125 and the center separator 30 and The U-turn section separator 125 may be completely opened without interference. Therefore, it is possible to prevent the U-turn section separator 125 from acting as an obstacle during the U-turn or the emergency U-turn section 50 is substantially narrowed.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
