[0006]

According to the construction of the route display marker according to the present invention, a flag is attached to the upper distal end of the mooring mast, and a rope connecting ring is attached to the lower proximal end of the mooring mast. Since a plurality of elastic mooring hooks protrude obliquely downward from the part in a radially symmetric distribution type, when the mooring mast is pushed upward from the ground to be mounted on the top of a tree, the mooring mast is elastically moored hook. In a so-called downside-down position, he can proceed smoothly to the top of the tree without hindrance.

The elastic mooring hook of the mooring mast, which has been pushed up from the top of the tree until the flag appears, is self-restoratively deployed and moored from above to the tree branch, and is further pulled down from the ground to remove the trunk. Combined with the tension of the rope tied to the branch, the branch is maintained in a stable and firm elastic pressure state on the branch, and even if it receives a natural external force such as a strong wind, it never falls.

Further, according to the method of attaching the route display marker to the tree according to the present invention, the required length from the ground to the top is determined by adding the extension pipe of the extension unit pipe and / or extending the extension unit pipe in the marker attaching tool. Not only can it be secured without any trouble, but also it is possible to conveniently store the marker mounting tool when not in use and carry it on site in a small and compact package.

[0009] Further, a rope is suspended from the mooring mast of the route display marker, and the mooring mast and the marker mounting tool are inserted so as to be freely inserted and removed. By strongly pulling down the ground from the ground, only the route display marker can be attached to the top of the tree in a residual state.

After a certain period of time, the used rope display marker can be removed from the tree by dropping the rope suspended from the above-mentioned route display marker artificially and strongly from the ground. Both the work of attaching the route display marker to the tree and the work of removing it can be performed easily and efficiently from the ground, and no skill is required in the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. First, FIGS. 1 to 4 show a route display marker (A) of an overhead power transmission line, and (11) shows a marker at a target point. A mooring mast moored to the top of a tree,
A fixed length (for example, about 3,000 mm) tapered taper tube made of fiber reinforced plastic such as glass fiber or carbon fiber is used, and a flag (12) is attached and used at the upper end side thereof. The flag (12) is colored pink or another colored color so that it can be easily recognized even from a distance such as the sky.

As the mooring mast (11), it is possible to adopt an entire single tapered taper tube. However, in the illustrated embodiment, in order to facilitate its packaging and carrying, the upper end side is used. (For example, about 1,50
0 mm) and the extension leg pole (11b), which is the same length as the lower base end side, can be freely connected to and unified from the flag attachment pole (11a).
To the flag (12).

That is, as is apparent from FIG. 3, the lower end of the flag mounting pole (11a) has a pin receiving hole (1).
3) is formed with an opening, while its extension leg pole (1) is formed.
The upper end of 1b) is formed in a stepped state as a thin plug-in joint (14). (15) is an arc-shaped leaf spring having one end fixed to the hollow interior of the insertion joint (14), and a connection penetrating through the insertion joint (14) from the free other end of the leaf spring (15). A pin (16) is integrally implanted in the radial direction.

The connecting pin (16) receives the back pressure of the leaf spring (15) and is always kept in a state of protruding from the circumferential surface of the insertion joint (14). Plug-in joint (14) for extension leg pole (11b)
Is inserted into the flag mounting pole (11a) from below, as soon as the connection pin (16) that has been immersed corresponds to the pin receiving hole (13) of the flag mounting pole (11a). The receiving hole (13) is received and locked by itself, and the flag mounting pole (11
a) and its extension leg pole (11b) are connected and integrated,
The result is a single mooring mast (11). In the connected state, both poles (11a) (11b)
Needless to say, the circumferential surfaces of the two become flush with each other.

On the other hand, a stainless steel band ring (17) is attached and fixed to the lower base end of the extension leg pole (11b) via a rivet or the like. (18) is a rope connection ring welded to the band ring (17),
A rope to be described later is connected and used for this. still,
A rope connecting ring may be fixedly integrated with the flag mounting pole (11a) via a similar band ring, and the ropes may be suspended from the rope connecting rings in several stages above and below the rope connecting ring.

Reference numeral (19) denotes a stainless steel base ring which is also fixed to the middle part of the extension leg pole (11b) by a rivet (20) or the like. A mooring hook (21) is integrally extended as a radially symmetric distribution type.

Each of the elastic mooring hooks (21) has a stainless steel mounting short axis (21a) and a long elastic wing (21) of a stainless steel coil spring extending continuously at the tip end thereof.
b) and its mounting short axis (21a)
Is welded to the circumferential surface of the base ring (19), while the protruding tip of the elastic wing (21b) is bent and raised as a stopper claw (21c).

As shown in FIG. 4, the elastic mooring hook (21) extends and extends in a direction tangential to the circumferential surface of the base ring (19) when viewed as a whole from the vertical direction. ing. Moreover, when viewed from the side, FIG.
As can be seen from FIG. 2, it extends obliquely downward and crosses the vertical center line of the extension leg pole (11b) by a certain angle (θ) (for example, about 45 degrees). It is set so that it can be stably and firmly moored to the branch.

Furthermore, the short mounting axis (21a) of each elastic mooring hook (21) is dimensioned to have a length (L1) (for example, 60 mm) substantially equal to the radius of the extension leg pole (11b). When the elastic wing (21b) is forcibly pushed and bent in a direction in which the elastic wing (21b) comes into close contact with the extension leg pole (11b), the tip of the mounting short axis (21a) is attached to the extension leg pole (11b).
b) so as not to protrude greatly outward from the circumferential surface.

On the other hand, the length (L2) of the elastic wing (21b)
(Approximately 200 mm) is longer than that of the mounting short axis (21a) and is in an obliquely downward posture at the above-mentioned constant angle (θ). However, when a pressing force exceeding the tension is applied from below, the automatic repulsion occurs. The tree is vertically turned upward, and the mooring state with respect to the tree branch is released.

The elastic mooring hook (21) is, as suggested by the modified embodiment of FIGS.
In particular, it can be fixed to the extension leg pole (11b) as upper and lower steps at a constant interval in the same manner as described above.
By doing so, even if the branches of the tree are thin and sparse, it is more and more effective in that they can be stably and firmly moored to the branches.

In any case, a portable cover sleeve (22) for the extension leg pole (11b) is prepared and prepared, and is inserted into the extension leg pole (11b) so that it can be freely inserted into and removed from above. Preferably, the elastic wings (21b) of the hook (21) are kept in a lying state in close contact with the circumferential surface of the extension leg pole (11b). Then, it can be safely and conveniently carried.

(26) is an arc-shaped leaf spring fixed at one end to the hollow interior of the insertion joint (25), and (27) is a connection integrally planted from the free other end of the leaf spring (26). It is a pin which is normally kept in a state of protruding from the circumferential surface of the plug-in joint (25) by receiving the elastic force of the leaf spring (26).

On the other hand, a receiving hole (2) for the connecting pin (27) is formed at the upper end of the refilling unit pipe (23a).
8) is correspondingly formed with an opening. Therefore, by using a plurality of the same extension unit pipes (23a), the insertion joint (25) located at the lower base end of one adjacent one as shown in FIG. Then, the one connecting pin (27) and the other pin receiving hole (28) are engaged with each other, and the connecting pole unit (2) having a required entire length (for example, about 9,000 mm) is engaged.
The result is unified as 3), and in this state, the circumferential surfaces of the adjacent refill unit pipes (23a) are flush with each other.

However, the uppermost extension unit pipe (23a) forming the connecting pole unit (23) is connected to the lower base end of the extension leg pole (11b) through a separate tapered taper joint pipe (29). However, if the connecting pole unit (23) is strongly pulled down to a high force, it can be easily removed from the extension leg pole (11b) of the mooring mast (11). Can be separated.

The tapered joint pipe (29) is also made of the same material as that of the refill unit pipe (23a), but as apparent from FIG. 7, its lower base end is located at the upper end of the refill unit pipe (23a). Straight pipe section to be inserted (2
9a), and the upper end is also tapered (29) inserted into the lower base end of the extension leg pole (11b).
b) In addition to being formed, a connecting pin (30) is provided in the hollow interior of the straight pipe portion (29a) to be engaged with the pin receiving hole (28) of the refill unit pipe (23a). A leaf spring (31) is also provided as an accessory.

It is to be noted that the tapered connecting pipe (29) between the flag mounting pole (11a) forming the mooring mast (11) and the extension leg pole (11b), and the taper connecting pipe (29) to the extension leg pole (11b). ) And the extension unit tube (23a), and between the extension unit tubes (23a) adjacent to each other, are connected by connecting pins (16), (27) and (30) so that they can be freely inserted and removed. Pin (16)
The leaf springs (15), (26), (3)
Although the back pressure of 1) is applied, as is apparent from the modified embodiment of FIG. 10 corresponding to FIG. 7, each of the leaf springs (16) (2)

May be urged constantly to protrude. (33) The coil spring (32) is connected to the extension leg pole (11b), the tapered connecting pipe (29), and the extension pipe (23).
It is a spring retainer sealed inside a).

The telescopic pole (24) mentioned above is provided with a plurality of telescopic unit tubes (24a) which gradually become thicker from the upper end to the lower base as shown in FIGS. The telescopic unit tube (24a) is made of a straight tube made of the same material as the connecting unit tube (23a) of the connecting pole unit (23). The total length of the telescopic pole (24) when the telescopic unit tube (24a) is stretched is, for example, about 8,000 mm, and the total length in the shortened state is about 1,600 mm. It can be stored.

Further, a pin receiving hole (34) corresponding to the connecting pin (27) of the extension unit tube (23a) is formed at the upper end of the narrowest telescopic unit tube (24a) of the telescopic pole (24). On the other hand, a step (35) for fixing a foot is fixed to the lower base end of the thickest telescopic unit tube (24a) so as to be rotatable in an up-and-down manner. When not in use, the step (35) can be turned down such that the step (35) is in close contact with the circumferential surface of the telescopic unit tube (24a).

The stretchable unit tube (24a) is in a stretchable slide fitting state as shown in FIGS.

That is, one of the thin telescopic unit tubes (24a
An eccentric joint pipe (36) is integrally connected to a lower base end of -1) through a rivet (37). The circumferential surface of the eccentric joint tube (36) is kept flush with that of the thin telescopic unit tube (24a-1). 38) is a cam surface which is eccentric with the telescopic unit tube (24a-1),
Moreover, a single locking pin (39) is protruded here.

Reference numeral (40) denotes a C-shaped stopper sheath made of rubber, synthetic resin, or the like, which refills the concave circumferential groove surface (38) so to speak. (41) are provided. Reference numeral (42) denotes a rotation guide slot which is also cut out along the arc surface of the stopper sheath (40), and is in a state of being locked with the locking pin (39) at one end of the slot (42). Then, the arc surface of the retaining sheath (40) is flush with the circumferential surface of the telescopic unit tube (24a-1), and is also engaged with the engaging pin (39) at the other end of the elongated hole (42). In this state, the arc surface of the retaining sheath (40) projects outward from the circumferential surface of the telescopic unit tube (24a-1) by a fixed amount.

For this reason, in a state where the arc surface of the stopper sheath (40) is flush with the circumferential surface of the telescopic unit tube (24a-1) as shown in FIGS. (24a-2) so that it can be freely inserted and removed and connected, and the two telescopic unit tubes (24a-1) (24
a-2) can be expanded and contracted. Thereafter, as shown in FIG. 20, when the two telescopic unit tubes (24a-1) and (24a-2) are relatively rotated, the stop sheath (30) is removed from the circumferential surface of the narrow telescopic unit tube (24a-1). It gradually protrudes and presses the inner peripheral surface of the thick telescopic unit tube (24a-2), and the two telescopic unit tubes (24a-
1) The connected state of (24a-2) is fixed and integrated, and the expansion / contraction operation is disabled.

However, FIGS. 21, 2 corresponding to FIGS.
As shown in the modified example of the second embodiment, a thick telescopic unit tube (24a-
While a male screw (43) is formed at the upper end of 2), a split piece (44) is attached to the lower base end of the thin telescopic unit tube (24a-1) inserted into the male screw (43). By rotating the bag nut (45) screwed with the screw (43),
The connection state of the two telescopic unit pipes (24a-1) and (24a-2) may be fixed and integrated by tightening and contracting the split piece (44).

When the bag nut (45) is loosened, the split piece (44) expands reconstructively, and the telescopic operation of the telescopic unit tubes (24a-1) and (24a-2) can be performed. Needless to say,

The flag attachment pole (11a) of the mooring mast (11) and the extension leg pole (11b) of the mooring mast (11) forming the route indication marker (A) are detachable and connectable, and the connection pole forms a marker attachment tool (B). Since the unit (23) is also composed of a plurality of unit pipes (23a) which can be freely inserted and removed, these units are completely disassembled, and the whole of the unit (23) is shortened by shortening the telescopic pole (24) of the marker mounting tool (B). It can be carried or stored in a small and compact package.

In preparation for the construction of the overhead power transmission line, when attaching the route display marker (A) to the top of the tree (C) located at the main point of the planned route, the mooring mast brought to the site (11) Flag mounting pole (1
1a) and the extension leg pole (11b) are inserted and integrated as shown in FIG.
One end of a long rope (46) is bound and fixed to the rope connecting ring (18).

Thereafter, a plurality of extension unit pipes (23a) are sequentially inserted and connected to the lower base end of the extension leg pole (11b) to be integrated as a connection pole unit (23) having a required entire length. , The connecting unit pipe (2) which forms the lowermost proximal end of the connecting pole unit (23).
3a), the upper end of the telescopic pole (24) is inserted and connected, and the telescopic pole (24) is fixed in an upwardly stretched state, so that the route display marker (A) is as shown in FIG. Then, a lifting operation is performed along the trunk of the tree (C) while avoiding the branches.

At this time, the step (35) attached to the telescopic unit tube (24a), which is the lowermost base end side of the telescopic pole (24), is grounded, and the step is stopped by the foot. The route display marker (A) and its mounting tool (B) are stably raised, and the push-up operation is performed with both hands.

Then, the elastic mooring hook (21) projecting from the temporary extension leg pole (11b) of the mooring mast (11) at the route display marker (A).
However, the flag mounting pole (11a) smoothly moves upward while splitting into the branches of the tree (C) because the flag mounting pole (11a) is resilient in the obliquely downward facing down posture state. )
Emerge from the top of the tree (C), with the result that the associated rope (46) hangs.

Then, next, the marker mounting tool (B)
From the ground to high power. Then, the flag mounting pole (11) of the route display marker (A)
a) and its extension leg pole (11b) are connected to the connecting pin (1).
6), and between the extension pipes (23a) of the connecting pole unit (23) and between the extension pipes (24) and the extending poles (24) are also fixed via the connecting pins (27). Therefore, the extension leg pole (11b) and the connection pole unit (23), which remain in the state of being inserted only by a simple taper fitting without passing through the connection pin, are separated from each other by themselves, and the route display marker is provided. (A)
Only the result remains at the top of the tree (C) as shown in FIG.

In the process, the extension leg pole (11
As a so-called outrigger, the elastic mooring hook (21) that protrudes from b) is securely attached to the branch of the tree (C) and moored by the wedge action in the obliquely downward posture state so as to protrude and unfold. It works.

Therefore, finally, the rope (46) suspended from the route display marker (A) is tied to the trunk of the tree (C) in a state of being pulled down from the ground as shown in FIG. In combination with the restoring elastic force of the elastic mooring hook (21), the route display marker (A) is fixedly maintained at the top of the tree (C). While packing and carrying the marker mounting tool (B) in a small and compact manner, the marker mounting tool (B) is moved to the next target point, and the mounting operation similar to the above is repeated for each point.

On the other hand, after a certain period of time, the route display marker (A) is removed, and a tower of an overhead power transmission line is constructed at that point. In removing the tower, the rope (46) is used. ) Is released from the trunk of the tree (C), and the lowering operation is performed vigorously as shown in FIG. Then, extend the pole (1) of the marker (A).
The elastic mooring hook (21) projecting from 1b)
It instantly reverses upwards, and the tree (C) is released from its mooring state and falls, and not only the marker (A) installation work but also the removal work can be performed easily and efficiently from the ground. is there.

In the illustrated embodiment, the marker mounting tool (B) is unitized from a pair of upper and lower members of a connecting pole unit (23) and a telescopic pole (24) used for connection thereto. By setting one overall length longer, the use of the other may be omitted.

[0048]

As described above, in the route display marker of the overhead transmission line according to the present invention, the mooring mast (1) composed of the tapered tapered tube of the fiber reinforced plastic has a structure.
Attach the flag (12) to the upper tip side of 1), and also attach the rope connecting ring (18) attached to the lower base end side of the mast (11).
The rope (46) is suspended from the mast (11), and a plurality of elastic mooring hooks (21)
Under the condition that the elastic mooring hook (21) of the mast (11) is moored from above to the branch of the tree (C). The mast (1) is pulled down by pulling down the rope (46) to the trunk of the tree (C) and tying it in tension.
1) is set so as not to fall, so that there is an effect that the problem of the prior art described at the beginning can be completely solved, and an experienced person climbs one tree at a time and ties a sign flag to the top of the tree. No fixing work is required.

That is, in the present invention, the flag (12) is connected to the upper end side of the mooring mast (11) forming the route display marker (A), and the rope (46) is connected to the lower base end side of the mooring mast (11). A ring (18) is attached to each, and a plurality of elastic mooring hooks (21) are integrally extended from the middle part of the mooring mast (11) as an overall radially symmetric distribution type obliquely downward. Therefore, the mooring mast (11) falls down to close the umbrella of the elastic mooring hook (21) in the process of being pushed up from the ground in order to attach it to the top of the tree (C) located at the target point. Under the posture state, the tree (C) branches into the branch and proceeds to the top without any trouble.

The elastic mooring hook (21) of the mooring mast (11), which has been pushed up from the top of the tree (C) until the flag (12) appears, expands itself and restores the tree (C). Moored to the branch from above, and together with the tension of the rope (46) pulled down from the ground, the branch is maintained in a stable and firm elastic pressure on the branch,
Even if it receives a natural external force such as a strong wind, it never falls and can achieve the original purpose of the flag (12).

In particular, if the configuration of claim 2 is adopted,
Of course, the above effects can be obtained, and by removing and disassembling the flag attachment pole (11a) and the extension leg pole (11b) of the mooring mast (11), it is possible to reduce the size and size of the mobile and portable device on site. It can be said that it is more convenient.

Further, if the configuration of claim 3 is adopted, each of the elastic mooring hooks (21) can be easily attached and fixed to the mooring mast (11), and the elastic wings (21b) can be attached.
Can be more reliably moored to the branches of the tree (C) by means of the stopper claw (21c) bent and raised from this, and the portable use and the miniaturization can be achieved by inserting the cover sleeve (22). There is also.

On the other hand, the route display marker (A) of the present invention
As a method of attaching to the tree (C) of the target point,
If the configuration of is adopted, the marker mounting tool (B)
Is required to be integrated as a required length from the ground to the top of the tree (C) by extending the extension unit tube (23a) and / or extending the extension unit tube (24a). It is possible to cope with the change in length without any trouble, and there is an effect that the marker mounting tool (B) can be conveniently stored and stored on-site in a compact and compact package.

A rope (46) is additionally suspended from the mooring mast (11) of the route display marker (A), and the mooring mast (11) and the marker mounting tool (B) can be freely inserted and removed. When the marker mounting tool (B) is strongly pulled down from the ground to a high force, the marker mounting tool (B) can be pulled out from the mooring mast (11) and separated. Only the route display marker (A) can be attached and fixed on the top of the tree (C) in a residual state.

Then, the rope (46) suspended from the route display marker (A) is also strongly pulled down from the ground, whereby the route display marker (A) is operated.
Can be removed from the tree (C) and dropped. That is, anyone can easily and quickly perform the work of attaching the route display marker (A) to the tree (C) of the target point and the work of removing the tree without the need for much labor and time.

Further, if the configuration of claim 5 is adopted,
Since the upper end of the marker mounting tool (B) is tapered as a tapered joint pipe (29), it is simply inserted into the mooring mast (11) of the route display marker (A) from below into a simple taper fitting state. (A) can be reliably pushed up to the top of the tree (C), and this operation can be performed lightly in a more stable standing posture by fixing the step (35) with a foot, and the marker mounting tool (B ) Is easily separated from the route display marker (A), and there is also an effect that only the route display marker (A) can be attached and maintained at the top of the tree (C).

In this case, if the marker mounting tool (B) is unifiedly connected and detachable from the connecting pole unit (23) on the upper end side and the telescopic pole (24) on the lower base side, it is pushed up. The required overall length from the ground to the top of the tree (C) can be easily secured long while maintaining the hand at the operation as small as possible and easy to hold, which is extremely useful in practical use. It can be said.
