Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tower climbing preventer for preventing people from climbing up a steel tower.

[Prior Art] High-voltage bare wires are installed on steel towers, and it is very dangerous for ordinary people such as children to climb up on them. Therefore, in order to prevent ordinary people from climbing the tower, a sixth
As shown in the figure, a tower climbing preventer 1 is attached to each of the four legs 9 of the steel tower 3.

This tower ascension preventer 1 includes an obstacle 2 and an obstacle 2.
and a mounting member 4 that is attached to the leg 9. The obstacle 2 includes a ring-shaped frame 27 arranged around the outer periphery of the leg 9. A plurality of rod-shaped members 7 are provided on the outer periphery of the frame 27 so as to protrude horizontally and in the radial direction. A mounting member 4 is provided in the diametrical direction of the frame 27. This mounting member 4 includes a pair of clamping plates 28, 28.
It is held between both sides of the leg 9 and fixed with bolts and nuts.

[Problems to be solved by the invention] However, according to this prior art, the tower ascension preventer 1
are provided separately on the four legs 9, so the legs 9
There was a problem in that people could climb up along the diagonal members 29 that diagonally connect the legs 9 and the horizontal members 18 that horizontally connect the adjacent legs.

Further, since the obstacle body 2 is provided horizontally, there is a problem in that during snowfall, snow gradually accumulates and develops, and the tower ascension preventer 1 breaks due to its weight.

This invention was devised to solve the above problems, and aims to reliably prevent ordinary people from climbing the tower, and also to prevent the tower climbing preventer from being destroyed even during snowfall. .

[Means for Solving the Problems] The present invention includes an obstacle consisting of a plurality of obstacle units each having a rod-shaped member inclined downward, and a mounting member for attaching the obstacle to the periphery of the tower midway in the height direction. This mounting member is composed of fixing metal fittings that are removably installed on the legs of the steel tower, and two horizontal frames, an inner and outer frame, that are attached to these fixing metal fittings and are arranged around both the inner and outer circumferences of the steel tower. Its composition is that it exists.

[Function] Therefore, not only the four legs of the steel tower but also the entire circumference in the height direction of the tower are blocked by the obstacles, and since the obstacles are made of bar-shaped members tilted downward, the snow is blocked. It falls without piling up.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 and 2, the tower climbing preventer 1 includes an obstacle 2 and a mounting member 4 for attaching the obstacle 2 to the periphery of the tower 3 midway in the height direction.

The obstacle 2, as shown in FIGS. 2 and 4,
It is constructed by arranging a plurality of obstacle units 5 in parallel. Each obstacle unit 5 is constructed by welding a plurality of rod-like members 7 near one end at appropriate intervals to the inclined surface of an elongated cross member 6 having a right triangular cross section and an inclined surface 6a at a predetermined angle. The other end sides of these rod-like members 7 are connected by a connecting rod 8.

As shown in FIG. 5, the mounting member 4 includes a fixing member 10 that is detachably attached to the four legs 9 of the steel tower, and a fixing member 10 that is attached at both ends to the fixing member 10 and is also attached to the adjacent legs 9. It consists of an outer horizontal frame 11 and an inner horizontal frame 12 which are arranged side by side. That is, both the inner and outer horizontal frames 12 and 11 of this mounting member 4 are arranged around the outer and outer circumferences of the steel tower 3 via the fixing fittings 10 to the legs 9.

The fixture 10 has a holding member 13 that comes into contact with the top 9a of the L-shaped member forming the leg 9. A pair of chevron-shaped protrusions 14, 14 are welded to this holding member 13, which abut on the end surfaces 9b on two sides of the leg 9. Legs 9 facing the holding member 13
An outer fixing member 17 is abutted on the end surface 9b side of. Both ends of this outer fixing member 17 protrude to the outside of the steel tower 3, and both ends are bent at a predetermined angle.
This bent portion 17a is parallel to the horizontal member 18 connecting the legs 9. Both ends of the outer fixing member 17 and the holding member 13 are fitted with bolts 19 and nuts 20.
It is fixed to the leg 9 with the leg 9 in between. One end of a pair of inner fixing members 21 extending inwardly of the steel tower 3 is fixed to the outer fixing member 17 . Both ends of the inner fixing member 21 are bent, and the bent portion 21a is parallel to the bent portion 17a of the outer fixing member 17. Both ends of the outer and inner horizontal frames 11 and 12 are fixed to the bent portions 17a and 21a of the inner and outer fixing members 17 and 21, respectively.

As shown in FIGS. 3 and 4, a plurality of obstacle units 5 are attached to the outer horizontal frame 11 in parallel in a direction in which the outer sides are inclined downward.

That is, as shown in FIG. 4, the cross member 6 of the obstacle unit 5 is placed on the upper surface of the outer horizontal frame 11, and is tightened and fixed with V bolts 22.

Similarly, an obstacle unit 5 is attached to the inner horizontal frame 12 so as to be inclined toward the inside of the steel tower 3. These outer and inner horizontal frames 1
The rod-like members 7, 7 on both sides of the obstacle unit 5 attached to the obstacles 1, 12 are connected at their upper ends by a connecting rod 23.

The lengths of the bar members 7, 7 of the obstacle units 5a, 5b provided at the corners of the steel tower 3 are approximately triangular, and a triangular corner frame 24 is fixed to the outer periphery. and,
The obstacle unit 5a at the outer corner of the leg 9, on which a safety wire (not shown) is provided, is attached so as to be openable and closable by a hinge 25, and is normally fixed by a screw 26. The robot can be moved up and down by loosening the screw 26 and opening the obstacle unit 5a at the outer corner.

Furthermore, a triangular obstacle unit 5c is fixed to the lower end of the obstacle unit 5 at each inner corner.

Next, the operation of this embodiment will be explained.

The obstacles 2 consist of bar-like members 7 that are inclined downward on the inside and outside of the steel tower 3, and are installed around the entire circumference of the steel tower 3 midway in the height direction, so that when it snows, snow falls along the bar-like members 7 without accumulating. At the same time,
It is possible to reliably prevent ordinary people from climbing the steel tower.

Further, the obstacle 2 has a plurality of obstacle units 5, 5.
a, 5b, and 5c are assembled to the outer side of the mounting member 4 and the inner horizontal frames 11 and 12 using V bolts 22, so they can be easily attached and detached to any position in the height direction of steel towers of various sizes. This has the advantage that it can be attached to.

[Effects of the invention] As is clear from the above explanation, the invention can reliably prevent ordinary people from climbing the steel tower, and also prevent the tower climbing preventer from being destroyed even during snowfall. effective.
