Description

  The present invention relates to a nesting material storage work network, and is particularly applicable when removing nesting such as a crow of a steel tower of a transmission line.

  Conventionally, crows and the like often nest on a steel tower of a transmission line that carries power supply. Depending on the location of the nesting, a part of the nesting material may come into contact with the electric wire, causing a ground fault and hindering power supply.

  For this reason, it is necessary to remove the nesting. In this nesting removal operation, the worker climbs the tower to the steel tower, removes the nesting and stores it in a storage bag, and descends with this storage bag.

  Various work nets used for removing this type of nesting material have been proposed, and one of them is a triangular storage net developed to be used for nesting removal in a steel tower (see Patent Document 1). . This is a triangular shape in which the base ends of a pair of bars are supported on the tip of an operation rod made of an insulating material, the tips of the bars are extended in a direction away from each other, and the tip of the operation rod is the apex. The two sides are formed with both bars, a net is stretched between the bars, and the nesting material from which the nesting is removed is stored in the net.

Japanese Patent Laid-Open No. 11-4648

However, the work network disclosed in Patent Document 1 has the following problems.
1) Since the shape of the net is triangular, the length of one side is larger than necessary to accommodate a nesting of about 80 cm (1.5 m), and there are difficulties in transporting and handling the main body.
2) Since it is basically an assembly type, it has the following drawbacks.
a) Before attaching the net, it is necessary to insert two 1.5m long bars into the handle and fix them. However, because it is a long object on the tower, it is necessary to pay attention to the surrounding live parts and it is difficult. This is a work that involves. In addition, there is a risk of accidentally dropping the bar. Here, a method of transporting the pre-assembled object to the steel tower is also conceivable, but in the assembled state, the total length is close to 2 m and it is difficult to ascend safely.
b) When attaching the net to the bar, it takes time and effort because of the method of tying the net at intervals of 5 cm with a string. In addition, the knot may be broken and the nesting material may be dropped.
3) Since the slack of the net is extremely small, the nesting capacity is poor.
4) Although the method of lowering the main body to the ground after containing the nesting material is not disclosed, it is practically extremely difficult for the worker to hold the main body and drop the tower from the tower while the nesting material is placed on the net. In addition, the nesting material may be scattered and dropped, which is not practical.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an entire nesting material storage work network according to an embodiment of the present invention. As shown in the figure, the nesting material storage work network I according to the present embodiment includes a support rod 1, a free net frame 6, and an outer net 9 as basic components. Here, the free net frame 6 is a portion attached to the tip of the support rod 1 and is a polygon (in this embodiment) that can be folded linearly by the net frame handle 2, the through frame body 3, and the plurality of net frame sides 4. It consists of a mesh frame 5 that can form a hexagonal shape. Further, the outer net 9 is locked to each net frame side 4 of the net frame 5 having a hexagonal shape through a plurality of net frame fixing clips 7 (six in the figure) arranged around the upper end portion thereof. Thereby, the opening part 8 based on a hexagon is formed. In this state, the outer net 9 becomes a bowl-shaped storage bag through the opening 8. In this embodiment, an inner bag 10 having a similar opening 11 is accommodated inside the outer net 9 so as to form a double accommodating portion.

  2A and 2B are diagrams showing an extracted portion of the free frame, where FIG. 2A is a plan view thereof, FIG. 2B is an enlarged view showing a through frame portion, and FIG. It is an expanded sectional view which expands and shows a portion. As shown in the figure, the mesh frame 5 includes a plurality of (six in this embodiment) mesh frame sides 4 that are sequentially connected to each other via two hinges 14 to each of the two groups of mesh frame rows 15A and 15B. The ends are pivotally attached to the tip of the mesh frame handle 2 via hinges 13A and 13B, respectively, and the tips of the mesh frame rows 15A and 15B are hinges 16A and 16B of the through frame 3. Are attached to each other in a rotatable manner. Thus, in the normal state, it is folded to form two rows of linear members (see FIG. 4 (a)), while each mesh frame side 4 is rotated via each hinge portion 13A, 13B, 14, 16A, 16B. To form a hexagon as shown in FIG.

  Here, the penetration frame 3 has an opening 3A that allows the support rod 1 (not shown in FIG. 2) to pass between the hinges 16A and 16B. Accordingly, the opening 3 </ b> A of the penetrating frame body 3 is on the extension line of the axis of the net frame handle 2, that is, on the axis line of the support bar 1. Here, the material of the net frame 5 is preferably a lightweight insulating material having a predetermined strength. For example, it can be suitably formed from polycarbonate. The diameter of the net frame 5 is preferably about 70 to 90 cm. This is because the nesting of crows is said to be about 50 to 70 cm, and it is necessary to have a size that can sufficiently cope with this.

  As clearly shown in FIG. 2B, each mesh frame side 4 is provided with a hole 4 </ b> A for inserting the tip of the mesh frame fixing clip 7 so as to lock the outer mesh 9. Further, the net frame handle 2 is inserted into the support rod 1 so as to be movable in the axial direction of the support rod 1, and as shown in FIG. It is a member. Here, facing the through-hole 2A through which the support rod 1 is inserted, a leaf spring 17 as an elastic member is disposed inside the mesh frame handle 2, and the mesh frame is interposed via the leaf spring 17. The handle 2 is fixed to the support rod 1. This will be described in detail together with the description of the support rod 1 using FIG.

  FIG. 3 is an enlarged view showing an extracted portion of the support bar 1 in this embodiment. As shown in the figure, the support rod 1 inserted through the through-hole 2A of the mesh frame handle 2 is preferably formed of a lightweight insulating material, and a plurality of connecting rods 1A that can be extended in the axial direction by being connected. Consists of. As a result, the overall length can be adjusted by selecting the number of connecting rods 1A to be connected. In addition, the support rod 1 is formed with slits 1B that are concave portions from the peripheral surface toward the center at a plurality of locations in the middle of the axial direction, and is disposed on the inner peripheral surface of the net frame handle 2 as described above. The position of the net frame handle 2 can be selectively fixed to the support bar 1 by elastically deforming the leaf spring 17 and fitting it into the slit 1B. Here, the slit 1 </ b> B is formed in an annular shape in the circumferential direction of the support bar 1, and has a structure in which the rotation of the net frame handle 2 around the axis of the support bar 1 is allowed. The support rod handle 12 at the base end portion of the support rod 1 serving as a worker's gripping portion is covered with a rubber cover so that it can be easily gripped, and a stopper 18 is provided at the tip of the support rod 1. This stopper 18 is for preventing the net frame handle 2 from coming off. That is, the stopper 18 has a diameter larger than that of the through hole 2 </ b> A of the mesh frame handle 2. Accordingly, the net frame handle 2 is restricted from further axial movement at the position where it abuts against the stopper 18. The support rod 1 is preferably formed so that the maximum dimension is about 1 m.

  FIG. 4 is a view showing an aspect of the main body (portion excluding the outer net and the inner bag) of the nesting material storage work net I according to the present embodiment, (a) is an initial state, and (b) is an intermediate state. , (C) respectively show the state when the assembly of the free net frame is completed.

  As shown in FIG. 4A, when not in use (normal time), the net frame handle 2 is in contact with the support rod handle 12 at the base end portion of the support rod 1, that is, has a minimum dimension. In such a state, two rows of net frame rows 15A and 15B each having its base end portion attached to the hinge portions 13A and 13B and each tip portion being attached to the hinge portions 16A and 16B are folded in parallel with the support rod 1. It is a linear member in a row.

  From the state shown in FIG. 4A, the mesh frame side 4 is rotated by rotating the mesh frame sides 4 via the hinge portions 13A, 13B, 14, 16A, and 16B. Form a hexagon as shown in b). At this time, the penetrating frame 3 moves downward in the figure, but since the tip of the support rod 1 including the stopper 18 can be passed through the opening 3A, the mesh frame 5 can satisfactorily have a predetermined hexagonal shape. Can be formed.

  By moving the mesh frame handle 2 in the distal direction (upward in the figure) along the support rod 1 from the state shown in FIG. 4B and fixing the mesh frame handle 2 at a predetermined position of the support rod 1. As shown in FIG. 4C, the assembly of the main body is completed. Here, the net frame handle 2 is fixed to the support rod 1 by inserting the leaf spring 17 into the slit 1B as described above.

  The outer net 9 and the inner bag 10 are set on the net frame 5 in the state shown in FIG. FIG. 5A is an enlarged view showing the outer net extracted, and FIG. 5B is an enlarged view showing the inner bag extracted. As shown in FIG. 2A, the outer net 9 is locked to each net frame side 4 of the net frame 5 widened in a hexagonal shape through a plurality of net frame fixing clips 7 arranged around the upper end portion. This is a net having a bowl-shaped storage part in which the opening 8 based on the hexagonal shape of the net frame 5 is formed. The material is formed of a strong material such as a fishing net having weather resistance that can be reused, and the size thereof is formed so as to be about 70 to 90 cm in diameter in accordance with the net frame 5. Here, a plurality (four in this embodiment) of surface tapes (magic tape (registered trademark)) 19 are disposed on the inner side of the upper end portion of the outer net 9 at opposite positions. The opening part 8 of the outer net | network 9 is closed by making 19 contact | abut. The outer net 9 is provided with two shoulder bands 20 so that the operator can carry the back with the opening 8 closed.

  The inner bag 10 is a bag for directly storing the nesting material disposed in the outer net 9 and removed. On the outside of the upper end of the inner bag 10, a similar surface tape 21 (only two are shown in the figure) is disposed at a position opposite to the surface tape 19 of the outer net 9. The inner bag 10 can be fixed to the inner side of the outer net 9 by bringing 19 and 21 into contact with each other. Furthermore, the upper surface of the inner bag 10 is provided with a surface tape 22 (only two sheets are shown in the figure) on the inner side at a position corresponding to the surface tape 21, and the surface tapes 22 facing each other are arranged. The opening part 11 of the inner bag 10 is closed by making it contact | abut. Further, the inner bag 10 is provided with a purse string 23 at the upper end thereof. The purse string 23 is used to completely close the opening 11 of the inner bag 10 having the opening 11 closed with the face tape 22 after storing the nesting material. As a result, the worker can completely prevent the nesting material from falling and scattering in the tower. Since the inner bag 10 directly stores the nesting material and discards it as it is, it is preferable that the inner bag 10 is made of a material that is not easily broken so that a branch or the like does not jump out and the odor is not easily leaked to the outside. For example, a nylon material is suitable. Further, the size is formed so that the diameter is about 70 to 90 cm in accordance with the outer net 9.

  The removal work of the nesting material using the nesting material storage work network I of this embodiment is performed in the following manner by a pair of workers. In this example, the nesting material nested in the steel tower is removed.

<Climbing work>
A worker raises the main body (support bar 1 and free net frame 6) and (outer net 9 and inner bag 10) folded in the state shown in FIG. The worker A who has climbed the tower to the specified height position assembles the main body at the work place according to the procedure shown in FIG. At this time, the surface tape 19 of the outer net 9 and the surface tape 21 of the inner bag 10 are brought into contact with each other to fix the inner bag 10 to the outer net 9, and the outer net 9 integrated with the inner bag 10 is In the state of FIG. 4B, the mesh frame is fixed to the holes 4 </ b> A (see FIG. 2) of the mesh frame sides 4 through the mesh frame fixing clips 7. Although this considers workability | operativity, you may latch the outer net | network 9 united with the inner bag 10 in the state of FIG.4 (c) to each net | network frame side 4. FIG. On the other hand, the other worker B climbs to the same height.

<Nest removal work>
Worker B removes the nesting from the tower. Such removal work is performed by the worker B removing the nesting in a state where the worker A grips the support rod 12 and projects the outer net 9 below the nesting. The B worker who has stored the nesting in the inner bag 10 closes the opening 11 by bringing the opposing face tape 22 into contact with each other, and then completely closes it with the drawstring string 23. Thereafter, the worker B removes the face tape 21 from the face tape 19 to remove the inner bag 10 from the outer net 9. However, the inner bag 10 is kept stored in the outer net 9. In this state, the opposing face tapes 19 are brought into contact with each other to close the opening 8 of the outer net 9 and remove it from the net frame side 4. Such removal is performed in the state shown in FIG. Thereafter, the worker A folds the main body in the reverse procedure of FIG. 4 and stores it.

<Trailing work>
The B worker uses the shoulder band 20 to descend the tower with the outer net 9 integrated with the inner bag 10 containing the nesting material. At the same time, worker A puts the main body into the portable cover and descends.

  According to this embodiment, the main body has a compact structure in which the support bar 1 and the flexible net frame 6 are integrated. When not in use, the main body becomes a linear compact member by folding, and when used, it is expanded into a hexagon. The assembly is completed by sliding the mesh frame handle 2 on the support rod 1.

  Here, the mesh frame 5 is structured to slide stepwise by the slits 1B carved in the support bar 1 and is also structured to be rotatable around the axis of the support bar 1 so that good workability is also achieved. Secured.

  Moreover, since the support bar 1 is a connection type, the length can be adjusted as necessary according to the work place. Furthermore, since the storage part is composed of the outer net 9 and the inner bag 10, it is excellent in airtightness and portability.

  In the above embodiment, the polygonal shape formed by the mesh frame 5 is a hexagon, but the present invention is not limited to this. Normally, it is folded to form two rows of linear members, while each mesh frame side 4 is rotated through each hinge portion 13A, 13B, 14, 16A, 16B, so that the shaft of the support rod 1 opens. Other polygons may be used as long as they form a polygon that can pass through the portion 3A. For example, a square or octagon may be used. However, since it is preferable to be close to a circle, a hexagon is preferable to a quadrangle, and an octagon is preferable to a hexagon. However, when a structure that increases the number of mesh frame sides 4 and does not become excessively complicated is selected. Hexagonal shape is considered appropriate.

  Further, it is not essential that the storage portion has a double structure of the outer net 9 and the inner bag 10. However, with the double structure as described above, the inner bag 10 can be sealed and discarded after the nesting material is stored, and the outer net 9 can be reused as it is.

  INDUSTRIAL APPLICABILITY The present invention can be used in an industrial field in which construction using a high space is performed near dangerous materials such as power transmission lines.
