Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a lifting fogproof fence for reducing the amount of fog flowing into the road, the entire fogproof fence is housed downward, and the fogproof fence does not block the surrounding landscape, In particular, the present invention relates to an elevating type anti-fogging fence with an excellent affinity with the landscape.
[0002]
[Prior art]
On roads where vehicles pass, various weather disturbances occur depending on various conditions such as topography and climate. In particular, when fog is generated on the road, the visibility of the vehicle driver is greatly reduced and the risk of an accident is increased. However, when roads are closed as a countermeasure against fog, punctuality and certainty as a means of transportation are remarkably lowered, which is not preferable.
[0003]
For example, (1) Improvement of visibility by installing a self-luminous delineator, road lighting, high-intensity road surface display, etc. (2) Guidance for safe driving by a special vehicle (pacemaker) Measures such as are taken. However, in the case of the fog countermeasures (1) to (2) , the vehicle running performance on the road is improved to some extent, but there is room for improvement because it does not eliminate the fog itself. In particular, since the running speed of the vehicle on the road is not uniform, the risk of a vehicle collision may be increased by the fog countermeasures (1) to (2) described above in the situation where the generation of fog is not improved. It is possible.
[0004]
Accordingly, a fog prevention fence formed by stretching a fine mesh for adsorbing mist particles between the columns is installed on the side of the road to reduce the amount of fog generated itself. This anti-fog fence can remarkably reduce the inflow of fog from the side of the road and is very effective as a countermeasure against fog because the installation and operation costs are low.
[0005]
[Problems to be solved by the invention]
However, the anti-fogging fence blocks the surrounding scenery in fine weather, so it is necessary to fully consider the affinity with the scenery, especially when installing the anti-fog fence in a scenic area. In addition, since the fog prevention fence may be damaged in a strong wind such as a typhoon, it is desirable that the fog prevention fence is stored in a state without fog. For this reason, there are fog barriers in the prior art that accommodate the net as a vertically movable type from such a request. However, even in this case, many pillars remain in the protruding state, so it is particularly improved in terms of compatibility with the landscape. There is room.
[0006]
On the other hand, as other conventional technologies capable of suppressing the generation of fog, a shelter or an air curtain is installed around a road (Japanese Patent Laid-Open Nos. 7-102532, 7-102533, and 7-102534), and far infrared rays. And those that make fog disappear by radiant heat or the like (Japanese Patent Publication No. 7-9084, Japanese Patent Laid-Open No. 2-204512, Japanese Patent Publication No. 5-287717, Japanese Patent Publication No. 7-81253). However, these conventional techniques have a large installation cost or operation cost, and are difficult to adopt in practice.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of an elevating fog barrier of the present invention will be described in detail with reference to the drawings.
[ 0015 ]
The fog prevention fence 1 of this embodiment is comprised from the expansion-contraction support | pillar 2, the fog prevention net 3, and expansion-contraction support | pillar drive means, such as the raising / lowering wire 4 and the main wire 5. FIG.
[0016]
The telescopic column 2 is composed of a plurality of columnar cylinders fitted in a nested manner, and is configured such that each columnar cylinder is moved in and out by an expansion / contraction mechanism using a lifting wire 4 and a pulley. FIG. 2 shows a state in which the telescopic column 2 is extended to the highest position, and FIG. 3 shows a simplified state in which the elastic column 2 is contracted to the lowest position.
[0017]
The telescopic strut 2 of the present invention has three outer cylinders 6, an inner intermediate cylinder 7 inside thereof, and an innermost inner cylinder 8 as a minimum basic configuration, and a plurality of intermediate cylinders 7 are used as necessary. It is configured in multiple stages. In the present embodiment, the outermost cylinder 6 with the largest diameter, the first intermediate cylinder 7a, the second intermediate cylinder 7b, the third intermediate cylinder 7c, and the inner cylinder with the smallest diameter embedded in the ground. The telescopic support column 2 is composed of a total of five cylinders with the body 8.
[0018]
In the present embodiment, the outer cylindrical body 6, the intermediate cylindrical body 7, and the inner cylindrical body 8 constituting the telescopic support column 2 are each formed in a regular hexagonal cross section. The outermost cylindrical body 6 having the largest diameter has the first intermediate cylindrical body 7a, the second intermediate cylindrical body 7b, the third intermediate cylindrical body 7c, and the innermost cylindrical body 8 having the smallest diameter in order from the outside to the inside. The body can be stored in a nested manner. In addition, the play which can pass the raising / lowering wire 4 is provided between each cylinder.
[0019]
A fixed band 9 made of a short cylinder having a regular hexagonal cross section that circumscribes the outer peripheral surface of the inner intermediate cylinder 7 is attached to the upper ends of the outer cylinder 6 and each intermediate cylinder 7. The fixed band 9 includes a halved cylindrical movable member 9a and a fixed member 9b. One end side of the movable member 9a and the fixed member 9b is connected to be freely opened and closed by a hinge mechanism 9c, and the other end side is configured to be connectable by a bolt 10 and a nut 11.
[0020]
The fixed band 9 has flanges 9d and 9e above and below the short cylinder. The outer cylinder 6 or the intermediate cylinder 7 and the fixing band 9 are fixed on the flange 12 previously provided by welding or the like on the upper end of the outer cylinder 6 or the intermediate cylinder 7 and the lower flange on the fixing band. 9e is overlapped, and only the portion of the fixing member 9b is bolted.
[0021]
In this embodiment, since the flange 12 and the movable member 9a of the outer cylinder 6 or the intermediate cylinder 7 are not fixed, the fixed band 9 and the inner cylinder can be obtained by strongly tightening the bolt connecting portion of the fixed band 9. The expansion operation or expansion / contraction operation of the cylinder can be stopped by the friction with the cylinder.
[0022]
That is, when the fixing band 9 is strongly tightened in the contracted state of the lifting column 2, it is possible to perform an ascending operation with an arbitrary cylindrical body integrally with the lower cylindrical body. In this case, the highest position of the telescopic support column 2 is reduced by the length of one cylindrical body. On the other hand, it is also possible to maintain and fix the extended state by firmly tightening the fixing bands 9 immediately below each other when the cylinders of the lifting column 2 reach the ascent limit.
[0023]
In addition, two bearing plates 13 arranged in parallel in the vertical direction are provided on the outer peripheral surface of the fixing member 9b. A suspension pulley 14 is attached to the upper side and a guide pulley 15 is attached to the lower side between the bearing plates 13 and 13. Further, on the outer peripheral surface of the movable member 9 a of the fixed band 9, a net support portion 18 for inserting the horizontal wire 16 and the vertical wire 17 protrudes.
[0024]
On the other hand, one support pulley 19 for winding the elevating wire 4 is arranged at the lower end of each intermediate cylinder 7 and inner cylinder 8, and the three guide rollers 20 are spaced 120 degrees apart from the central axis. It is installed at. The guide roller 20 abuts on the inner peripheral surface of the cylinder located on the outer side to rotate, thereby eliminating rattling between the cylinders and reducing the expansion and contraction movement of the cylinders as much as possible. Plays a role in stabilizing the state.
[0025]
A mounting flange 21 having a diameter smaller than the inner diameter of the outer cylinder is fixed to the outer peripheral surfaces of the lower ends of the intermediate cylinders and the inner cylinder in advance by means such as welding. A regular hexagonal mounting plate 22 is applied to the lower surface of the mounting flange 21 and is fastened and fixed with a downward bolt 10. The guide roller 20 is supported on the lower surface of the mounting plate 22 by two L-shaped brackets 23.
[0026]
5 and 6, the support pulley 19 is pivotally supported above the guide roller 20 in the bracket 23 on the right side. At the mounting position of the support pulley 19, the mounting flange 21 and the mounting plate 22 are provided with a gap L equivalent to the interval between the two brackets 23, 23, and the lifting wire 4 is moved up and down through the gap L. It is possible to pass vertically.
[0027]
When the telescopic column 2 is assembled, the support pulley 19 and the guide roller 20 are attached to the lower end of the intermediate cylinder 7 or the inner cylinder 8 together with the mounting plate 22 in advance, and the elevating wire 4 is wound around the pulley. Fit the cylinder into the inside of the outer cylinder. Thereafter, assembly can be performed relatively easily in the order of attaching the fixing band 9 to the upper end of the cylindrical body. In the fixed band 9 of the present embodiment, the movable member 9a and the fixed member 9b are connected to each other by a hinge mechanism 9c so as to be freely opened and closed. Attachment can also be performed easily.
[0028]
In addition, one elevating wire 4 is disposed on each telescopic support column 2, and the elevating wire 4 is stretched around a pulley of each cylindrical body. The telescopic strut 2 is extended by the tension of the elevating wire 4, and the telescopic strut 2 is contracted by the relaxation of the elevating wire 4.
[0029]
The elevating wire 4 is wound around a support pulley 19a provided at the lower end of the first intermediate cylinder via a suspension pulley 14 provided at the upper end of the outer cylinder 6 so as to be reversed upward, and the first intermediate It rises upward along the inner wall surface of the cylindrical body 7a.
[0030]
The elevating wire 4 rising upward along the inner wall surface of the first intermediate cylinder 7a passes through the gap L between the attachment flange 21 and the attachment plate 22 of the second intermediate cylinder 7b and passes through the first intermediate cylinder 7b. It is once led out of the upper end of the first intermediate cylinder 7a through the guide pulley 15a at the upper end of 7a. The elevating wire 4 led outward is wound around a suspension pulley 14a provided at a position directly above it from the outside to the inside, and is inverted downward again to the inside of the first intermediate cylinder 7a. Therefore, in this embodiment, it is not necessary to provide a gap between the cylinders by the amount of the suspension pulley 14 and the guide pulley 15, and the gap is minimized.
[0031]
Thereafter, the lifting / lowering wire 4 is wound around the support pulley 19b provided at the lower end of the second intermediate cylinder 7b from the outside to the inside and reversed upward, and upward along the inner wall surface of the second intermediate cylinder 7b. Standing up. Therefore, in this embodiment, in order to pass the lifting wire from the outer cylinder 6 to the inner cylinder 8, it is unnecessary to form a slit on the wall surface of the cylinder.
[0032]
In the manner described above, the elevating wire 4 includes the guide pulley 15b and the suspension pulley 14b at the upper end of the second intermediate cylinder 7b, the support pulley 19c at the lower end of the third intermediate cylinder 7c, and the guide pulley 15c at the upper end of the third intermediate cylinder 7c. And the suspension pulley 14c and the support pulley 19d at the lower end of the inner cylinder 8 are respectively wound around. The elevating wire 4 that rises upward along the inner wall surface of the inner cylindrical body 8 is fixed at the end of the inner cylindrical body 8 at the end.
[0033]
On the other hand, the other end of the lifting wire 4 passes through a pulley 4b fixed to the lifting column as shown in FIG. 9, and is connected to the connecting portion 5a of the main wire 5 via a turnbuckle 4a.
[0034]
The main wire 5 extends across the plurality of telescopic struts 2 in a direction substantially parallel to the ground surface, and the end of the main wire 5 is connected to the drive device 27. Then, by pulling the main wire 5 in the tensioning or relaxation direction of the lifting / lowering wire 4 by the driving device 27, the lifting / lowering wire 4 extended from each lifting / lowering strut 2 is tensioned / relaxed, and the plurality of telescopic struts 2 are synchronized. To go up and down.
[0035]
Further, an upper pipe 24 extending substantially parallel to the ground surface along the road extending direction is connected to the outer side of the upper end portion of the inner cylindrical body 8 of the telescopic support column 2. The net support 18 provided on the fixed band 9 of the telescopic strut 2 includes a horizontal wire 16 stretched in a direction substantially parallel to the ground surface, and a vertical wire 17 stretched along the telescopic strut 2. Are crossed in a cross shape. And the fog prevention net | network 3 is stretched from the outer side of the road 26 so that the upper pipe 24, the horizontal wire 16, and the vertical wire 17 may be contacted.
[0036]
In the present embodiment, a polyester Russell net is used for the fog-proof net 3, and the size of the net is set to a fineness of about 1 to 2 mm. The upper edge portion of the fog-proof net 3 is fastened to the upper pipe 24 and is bound to a plurality of horizontal wires 16 or vertical wires 17 by clips 25 or the like. Further, the lower edge portion of the fog-proof net 3 is locked to the net support portion of the outer cylindrical body 6. Note that the vertical wire 17 may be omitted when the fog-proof net 3 has rigidity to withstand wind.
[0037]
Further, as in the present embodiment, the anti-fogging net 3 does not need to be configured by a single net, and may be configured to be divided into a plurality of nets [not shown]. In this case, since only the net having a broken portion can be replaced when the fog-proof net is broken, the maintainability is improved.
[0038]
The elevating fog proof fence 1 of the present embodiment is configured as described above, and hereinafter, the rising and falling states of the fog proof fence 1 will be described.
[0039]
When fog occurs in the vicinity of the road 26, the main wire 5 is pulled in the tension direction of the lifting wire 4 to bring the anti-fogging fence 1 into an elevated state. In the telescopic support column 2 of this embodiment, a kind of boosting mechanism is configured by the lifting wire 4, the suspension pulley 14, and the support pulley 19. Therefore, the tension | tensile_strength of the expansion-contraction support | pillar 2 can be performed by comparatively small load by tensioning the raising / lowering wire 4 from the state which contracted the expansion-contraction support | pillar 2 to the lowest position like FIG.
[0040]
In the elongating operation of the lifting column 2, the inner cylinder 8 having the smallest diameter and the lightest weight is first pulled out and raised. Then, when the mounting flange 21 of the inner cylinder 8 hits the lower flange 9e of the fixed band 9 of the third intermediate cylinder 7c and reaches the ascent limit, the next lighter third intermediate cylinder 7c is raised. Begin.
[0041]
Further, after the third intermediate cylinder 7c and the second intermediate cylinder 7b reach the ascent limit, the extension operation of the telescopic support column 2 is performed in the order in which the first intermediate cylinder 7a starts to rise. When the first intermediate cylinder 7a reaches the rising limit, the telescopic support column 2 is extended to the longest state. In the present embodiment, the length of one cylinder is about 1.6 m, and the total of the four cylinders extends to a height of about 6 m above the ground.
[0042]
As the telescopic support column 2 extends, the anti-fog net 3 and the vertical wire 17 which are bent and ground in the contracted state of the expandable support column 2 are stretched and deployed, and the anti-fog fence 1 is in an elevated state. In the rising state of the fog proof fence 1, the mist flowing into the road 26 from the outside of the fog proof fence 1 is adsorbed on the fog proof net 3 when passing through the fog proof fence 1 and flows down as water droplets. Therefore, the inflow of fog from the outside of the fog barrier 1 to the road 26 is remarkably reduced and the amount of fog on the road 26 side is suppressed, so that the field of view of the vehicle driver is kept relatively good.
[0043]
On the other hand, when fog is not generated, the main wire 5 is pulled in the loosening direction of the elevating wire 4 to bring the antifogging fence 1 into a lowered state. When the fog-proof fence 1 is lowered, the lifting wire 4 is relaxed, so that the cylindrical body moves downward due to its own weight and the telescopic support column 2 contracts. As the telescopic support 2 contracts, the anti-fogging net 3 and the vertical wire 17 that have been deployed when the anti-fogging fence 1 is raised are grounded while being bent downward.
[0044]
In the descending state of the fog barrier 1, the upper ends of the fog net 3 and the telescopic support 2 are both located near the ground surface, so that the surrounding landscape is not obstructed and the compatibility with the landscape is very good. .
[0045]
Although the embodiments of the present invention have been described above, the claims of the present invention are not limited to these embodiments. For example, instead of the regular hexagonal cross section, the cylindrical body constituting the lifting column 2 can be formed in a cross-sectional shape such as a circle, a square, or another polygon.
[0046]
Moreover, it is good also as a structure which accommodates each curved cylinder in a nested shape, and curves a raising / lowering support | pillar. It is also possible to cover the road in an arch shape with a fog-proof fence or to cover the fog-proof fence in a tunnel shape by curving the lifting column.
[0047]
【The invention's effect】
The elevating type anti-fogging fence according to the present invention can store the telescopic strut and the anti-fogging net near the ground surface by lowering the fog-proof fence when there is no fog. Therefore, in the state where fog is not generated, the telescopic support column and the fog-proof net do not block the surrounding landscape, and the compatibility with the landscape is very excellent.
[0048]
Moreover, the elevating type anti-fogging fence for the present invention can block the inflow of fog from the outside of the elevated road by setting the anti-fogging fence to a raised state when fog is generated. Therefore, even when fog is generated around the elevated road, the amount of fog in the elevated road is suppressed by the fog barrier, so that the visibility of the vehicle driver is kept relatively good.
[0049]
Moreover, the elevating type anti-fogging fence according to the present invention can be easily installed, and is excellent in workability and cost. In particular, the drive of each telescopic strut is performed in synchronization with the pulling of one main wire, so that maintainability is also excellent.
