Description

Up-down type mist blocking net device to block ingress of fog that impedes traffic

The present invention relates to a lifting type netting apparatus installed on a roadside or a bridge side, and more particularly, a passage designed to effectively block fog from entering a road or a bridge through a netting that slides by winding and unwinding a wire. It is related with a lifting type netting net device for blocking the inflow of the obstacle of the fog.

On roads where vehicles pass, various weather obstacles occur depending on conditions such as terrain and climate. In particular, when a fog occurs on the road, the driver's view of the driver drastically deteriorates and the risk of accidents increases. However, when prohibiting the passage of roads as countermeasures against fog, it is not preferable because regularity and certainty as transportation means are considerably lowered.

To increase the visibility of the road in the event of a fog, a lighting device or a high-brightness road surface display device is installed on the road to improve the visibility. However, this does not prevent the occurrence of fog, It is not possible to reduce the risk of collision of the vehicle.

Accordingly, there has been proposed a method of reducing the amount of fog generated by installing a wall or a small-sized wall mounted between the struts between a narrow net for adsorbing mist particles. However, if the fog does not occur, the wall will block the surrounding landscape. Therefore, the affinity with the landscape should be taken into consideration. In addition, there is a risk of breakage in strong winds such as typhoons, and when installed in a bridge, it acts as an unfavorable load on the bridge, so it is preferable that the wall is accommodated in the absence of fog.

As a background technology of the present invention, there is a Japanese Patent Application Laid-Open No. 2004-19235, "Highly Available Lifting Method." In this prior art, a plurality of lifting posts provided at equal intervals outside the sidewall railing of an elevated roadway, a spinning net fixed in a state mounted between the lifting posts, and driving means for driving the lifting posts in the vertical direction Comprised of, and discloses a high-priced lifting type barrier that the lifting column and the spinning net is lowered along the side wall railings. However, the method proposed in the prior art is applicable only to elevated roads, and it is difficult to apply when there is no space for the elevating landlord to descend.

The base 20 has a frame structure whose upper surface is formed in a rectangular shape and reinforced by welding various angles. The base 20 has, for example, anchor bolt holes at various places around the concrete to be fixed to the concrete.

A driving unit 30 for generating a rotational output is provided on one side of the upper surface of the base 20. As shown in FIG. 1C, the driving unit 30 includes a driving motor 32 and a speed reducer 34 that receives the rotational force of the driving motor 32 and generates an output with reduced rotation. The output end of the drive motor 32 and the input end of the speed reducer 34 are connected to the first chain 31.

A wire drum 40 having a drum rotation axis 42 is installed on one side of the driving unit 30. [ The drum rotation shaft 42 is positioned in the width direction of the base 20. The drum rotary shaft 42 is supported by the bearing and is connected to the output end of the speed reducer 34 through the second chain 33. The wire drum 40 is provided with a partition plate 41 at the center of the outer circumferential surface so that the two lifting wires 50a and 50b can be separated and wound. Therefore, the wire drum 40 rotates in the forward and reverse directions via the speed reducer 34 in accordance with the rotation direction of the drive motor 32.

The first lifting wire 50a is wound on one side of the partition plate 41 and the second lifting wire 50b is wound on the other side of the wire drum 40. [ At this time, one end of the first lifting wire 50a is fixedly wound around one side of the wire drum 40 based on the partition plate 41, and the other end thereof is the first net frame guide assembly 60a as shown in FIGS. 1A and 2. ) One end of the second lifting wire 50b is fixed on the other side of the wire drum 40 with respect to the partition plate 41 and the other end thereof is connected to the second net frame guide assembly 60b. A pair of guide rollers 15a and 15b fixed to the upper surface of the base 20 are provided between the first net frame guide assembly 60a and the wire drum 40 to guide the winding of the lifting wires 50a and 50b. ).

A first net frame guide assembly 60a and a second net frame guide assembly 60b are installed on the upper surface of the base 20 on both sides. The first net frame guide assembly 60a is vertically movable along the winding direction of the first lifting wire 50a and the second net frame guide assembly 60b is moved along the winding direction of the second lifting wire 50b So that it can move up and down. The first lifting wire 50a and the second lifting wire 50b are connected to one wire drum 40 so that the first net frame guide assembly 60a and the second net frame guide assembly 60b ) Simultaneously operate in a sliding manner. The first net frame guide assembly 60a and the second net frame guide assembly 60b have the same structure, but their placement directions are opposite to each other.

Thus, any one of the first net frame guide assemblies 60a will be described. 2, the first net frame guide assembly 60a includes a lower rail 61 disposed one side forward and an upper rail 66 and a lower rail 61 disposed at the rear of the lower rail 61, And a plurality of intermediate rails (62, 63, 64, 65) disposed between the upper rail (66) and adjacent ones of the intermediate rails (62, 63, 64, 65). Of course, the first intermediate rail 62 is coupled to the lower rail 61 and the upper rail 66 is slidably coupled to the fourth intermediate rail 65. The number of the intermediate rails is not limited to this, and can be increased or decreased, and accordingly, the height of the wall can be increased or decreased. These rails 61 to 66 all have the same size cross section having a C shape with the ribs 61a as shown in FIG. 6. The rails 61 to 66 may be made of a lightweight aluminum material, for example.

Wire rails 161, 162, 163, 164 and 165 are provided at the upper ends of the lower rail 61 and the middle rails 62, 63, 64 and 65, respectively. The reaction force wires 162a, 163a, 164a and 165a are connected to the wire rollers 162, 163, 164 and 165 of the corresponding rails and the reaction force wires 162a, 163a, 164a and 165a are connected to the intermediate rails 62, Are connected and fixed to the lower ends of the adjacent rails. For example, the first reaction force wire 162a is hooked on the wire pulley 162, and one end of the first reaction force wire 162a is fixedly connected to the lower end of the lower rail 161 adjacent to the one side, and the other end is connected to the second intermediate rail 63, As shown in FIG. The second reaction force wire 163a is hooked on the wire pulley 163 and is fixedly connected to the lower end of the first middle rail 62 whose one end is adjacent to one side and the lower end of the third intermediate rail 64 whose other end is adjacent to the other side As shown in FIG. In this way, the last reaction force wire 165a is connected to the wire pulley 165 and fixed at the lower end of the third middle rail 62, one end of which is adjacent to one side, and the other end is connected to the lower end of the upper rail 66 adjacent to the other end And is fixedly connected.

The first lifting wire 50a is hooked on one guide pulley 15a and is connected to the wire pulley 161 of the lower rail 61 and fixedly connected to the lower end of the first middle rail 62. [

Therefore, when the first lifting wire 50a is wound around the wire drum 40 and pulled, the first lifting wire 50a is supported by the wire pulley 161 as shown in FIG. 3a so that the first lifting wire 50a lifts the lower end of the first intermediate rail 62. do. Whereby the second intermediate rail 62 ascends. When the second intermediate rail 62 rises, the first reaction force wire 162a lifts up the third intermediate rail 63 while being supported by the wire rollers 162. When the third intermediate rail 63 rises, the reaction force wire 163a lifts up the fourth intermediate rail 64 while being supported by the wire pulley 163. When the fourth intermediate rail 64 rises, the reaction force wire 164a lifts up the fifth intermediate rail 65 while being supported by the wire rollers 164. When the fifth intermediate rail 65 rises, the reaction force wire 165a lifts up the sixth intermediate rail 65 while being supported by the wire rollers 165.

When the first lifting wire 50a is wound on the wire drum 40, the wire length of the section connected to the fixed end of the wire drum 161 and the intermediate rail 62 is shortened, The intermediate rails 62, 63, 64, and 65 and the upper rail 66 are raised to be approximately in a straight line. At this time, the upper rail 66 is located at the uppermost position and the intermediate rails 62, 63, 64, 65 are sequentially deployed between the lower rail 61 and the upper rail 66 to be lowered.

The second net frame guide assembly 60b has the same structure as the first net frame guide assembly 60a. However, the lower rail 61, the upper rail 66, and the plurality of intermediate rails 62, 63, 64, and 65 are disposed in opposite directions. Of course, these rails may be installed in the same direction as the first net frame guide assembly 60a. The other end of the second lifting wire 50b is switched to the guide pulley 16 and wound around the first wire pulley 161 on the lower rail 61 to be fixed to the lower end of the second middle rail 62. Thus, the second net frame guide assembly 60b simultaneously engages with the first net frame guide assembly 60a during the winding rotation of the wire drum 40. [

The first net frame guide assembly 60a and the second net frame guide assembly 60b are provided with a plurality of net frames 71 to 76 as shown in FIG. 3B. Here, the net frames 71 to 76 are provided in the form of a rectangular frame having a lattice structure and the same number as the number of the rails 61 to 66. The net frames 71 to 76 can be made of lightweight aluminum.

The plurality of net frames 71 to 76 are provided with the nets 71a, 72a, 73a, 74a, 75a, and 76a, respectively, as shown in FIG. 4A. The veneer nets 71a to 76a may be made of any material known in the art to block the entry of fog into the roads. As an example, Bangunnett can be composed of a narrow fabric made of carbon fiber, glass fiber, or a mixture of these fibers.

On the other hand, when the plurality of moving rails 62, 63, 64, 65, and 66 are erected, the security net 71a to 76a is bent in an arch shape toward the road side. That is, the non-security nets 71a to 76a prevent the apparatus from being introduced into the road by inducing the apparatus to pass over when the mist overflows. For this purpose, when viewed from the side of the road, the vending nets 71a to 76a are set up in an arch shape.

To this end, each of the upper and lower sliding pads 81 and lower sliding pads 82 are disposed on the lower side of each of the moving rails 62 to 66 at a predetermined adjacent side of the moving rail as shown in FIGS. ) Is provided, and the upper and lower sliding pads 81 and 82 have a predetermined inclination angle θ toward the net frames 71 to 76. Accordingly, after the plurality of moving rails 62 to 66 are raised, the net frames 72 to 76 of the plurality of stages are erected in the shape of an arch with an inclination λ along with the nets 72a to 76a. The pads 81 and 82 are coupled to the I-shaped pad support plate 85 and the pad support plate 85 is bolted to the U-shaped angle 86 joined to the rail side.

Described is the operation of a ramp-type security device to block the flow of fogs that cause obstacles to the traffic thus constructed.

First, this non-residential network device is installed, for example, on the side of the road 100 or on the side of the bridge. The operation of the security net device installed on either side of the road side will be described. At this time, the base 20 is fixed to the floor of the road side.

When the first and second net frame guide assemblies 60a and 60b are folded as shown in FIG. 1A, the intermediate rails 62, 63, 64 and 65 and the upper rail 66 are all lowered to lower the rail 61. It is located side by side on one side.

When a firewall is required in this state, it is mostly detected by the automatic fog and operated by a control device (not shown) that controls the firewall. In this case, the sensing means is a well-known technique in this field and is omitted. When the fog is detected and the drive motor 32 rotates forward, the wire drum 40 rotates counterclockwise in FIG. 4A through the reducer 34 to simultaneously wind the first and second lifting wires 50a and 50b. .

The first and second lifting wires 50a and 50b are pulled while being wound on the wire drum 40 so that the intermediate rails 62, 63, 64, and 64, which constitute the first and second net frame guide assemblies 60a and 60b, 65 and the upper rail 66 are simultaneously raised. At this time, the rear rails are moved to a higher position than the front rails by reaction force wires 162a, 163a, 164a, and 165a, so that the intermediate rails 62, 63, 64, 65 and the upper rails as shown in FIGS. 66 is erected upward from the lower rail 61, the net frame (72 ~ 76) is raised upward through the arms (92 ~ 96) in conjunction with this, the radio nets (71a ~ 76a) overlapping each other It expands upwards to block fog from entering the road.

At this time, the control of the amount of forward rotation of the wire motor 32 may be performed using a set value or a sensing device such as a switch for detecting that all the moving rails are unfolded.

On the other hand, when the nets 71a to 76a are all unfolded as shown in Fig. 4A, the inclination angles θ of the upper and lower sliding pads 81 and 82 provided between the neighboring rails are inclined toward the inside of the road. Since it is erected in the form of an arch with (λ), as well as blocking the fog flowing from the side to the road side, the fog that flows over the net is not flowed to the road side and can be further enhanced as shown in FIG. 4b. have.

As described above, according to the present invention, the first and second lifting wires 50a and 50b are simultaneously interlocked so that the net frames 72 to 76, which are long in the longitudinal direction (the longitudinal direction of the road) 76a are improved.

In addition, when the veneer nets 71a to 76a are upright and all are unfolded, they are inclined in an arch shape to the road side so that the mist passes over the uppermost veneer net 76a, thereby effectively preventing fog from being introduced into the road .

On the other hand, when the mist is not removed or there is no mist, the drive motor 32 is driven to rotate reversely so that the wire drum 40 releases the first and second lifting wires 50a and 50b. At the same time, 76 are lowered and the veneer nets 72a to 76a are folded, so that the structure is not affected by the wind load and the sea surface is not damaged.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
