Description

  The present invention operates a rope member connected to the apparatus main body to move the apparatus main body along the overhead line, thereby removing flying objects such as bags and vinyl attached to the overhead line. It relates to the device.

  Flying objects such as dredging and agricultural vinyl are often attached to overhead lines such as overhead power transmission lines and overhead communication lines between steel towers due to strong winds. In such a case, conventionally, a flying device (flying object removing device) as shown in FIG. 7 is used to remove flying objects attached to the overhead wire.

  The apparatus shown in FIG. 7 removes flying objects attached to the overhead line 102 by operating the rope 101 connected to the apparatus body 100 and moving the apparatus body 100 along the overhead line (power transmission line) 102. Two traveling rollers 103, 104 arranged at intervals in the longitudinal direction of the overhead wire 102, front and rear guide rollers 105, 106, a support frame 107 that supports the plurality of rollers, A drooping member 108 extending downward from the overhead wire 102 from the support frame 107 is provided with a saw-shaped cutting blade 109 for cutting and removing flying objects.

  In order to place this scraping device on the overhead wire 102, throw either the left or right rope so that the overhead wire 102 is sandwiched from the ground with the ropes 101 on the left and right of the device main body 100, while pulling the one rope, By driving out the other rope, the traveling rollers 103 and 104 of the apparatus main body 100 are placed on the overhead wire 102. Then, by pulling out a total of four ropes, two left and right on the ground, by four persons, the flying object is cut and removed by the cutting blade 109 attached to the hanging member 108.

However, such a conventional scraping device has the following problems.
(1) When the apparatus main body 100 is placed on (attached to) an overhead wire from above the steel tower, it is not structured to be able to pass through the vibration-damping damper ahead of the steel tower of the steel tower (the interval between the hanging members 108 is Therefore, the position where the apparatus main body 100 is mounted is ahead of the vibration preventing damper. That is, a rope is thrown from above the steel tower to a position on the overhead line several meters away from the steel tower, the rope is guided to the ground, the rope and the apparatus main body 100 are connected on the ground, and then the overhead wire 102 is operated while operating the rope from the ground. The apparatus main body 100 must be mounted in a state where it can be lifted up, and even if this work is performed by an experienced person, a great deal of labor is required.

(2) When the apparatus main body 100 is installed on the overhead line 102 and travels to the position of the flying object to be removed, the traveling rollers 103 and 104 repeatedly derail the overhead line, and the apparatus main body parts other than the rollers also become overhead lines. Touch repeatedly. Therefore, after temporarily stopping the traveling operation of the apparatus main body 100, it is necessary to reattach the apparatus main body to the overhead wire so that the apparatus can travel, and it takes a lot of labor and time to reach the target position.

(3) If there is an overhead wire twist prevention damper while the apparatus main body 100 is running, the damper may be caught between the rollers when the apparatus main body 100 passes, and it may not be able to run. In order to remove the catch and make it possible to run, it is necessary for a ground worker to apply a large force (pulling) to the rope 101 connected to the apparatus main body 100 to cause the apparatus main body 100 to be raised from the damper. As a result, an excessive force is applied to the roller, and the rotation axis of the roller is distorted.

(4) When the apparatus main body 100 is attached to the overhead wire 102, the cutting blade 109 is linearly extended downward, so that a flexible flying object such as nylon adheres to the overhead wire 102. , May be difficult to remove.

(5) After completing the removal of flying objects, sufficient experience is required to lower the apparatus main body 100 to the ground at that position by rope operation. In particular, if the timing of detaching (removing) the apparatus main body 100 from the overhead wire 102 by swaying with a rope operation is shifted, the apparatus main body 100 is caught on the overhead wire, and the apparatus main body 100 cannot be easily lowered. Such a problem also occurs when the apparatus main body 100 is mounted (mounted) on the overhead wire 102 by rope operation.

Note that Patent Literature 1 describes a technique of an attached power collecting device for an overhead power transmission line. This technology includes a plurality of guide rollers that can move while rotating along the longitudinal direction of the overhead power transmission line, and iron oxide and salt that adhere to the surface of the overhead power transmission line while contacting and rotating the overhead power transmission line. A rotating brush for scraping off the deposits and a collection container for the scraped deposits are provided. However, although the apparatus described in Patent Document 1 is suitable for removing deposits such as rust and salt, it is not applicable as a technique for removing flying objects such as straw and agricultural vinyl.

  The flying object removing device of this embodiment includes a device main body 1 attached to the overhead wire K, and a rope member 2 made of an insulating rope connected to operate the device main body 1. The apparatus main body 1 includes front and rear traveling rollers 3 and 3 arranged at intervals in the longitudinal direction of an overhead power transmission line (overhead wire) K, a support frame 4 that supports the front and rear traveling rollers 3 and 3, and a support A hanging member 5 extending downward from the overhead line K from the frame 4 and a cutting blade 6 provided on the hanging member 5 for cutting and removing flying objects are provided. The position of the center of gravity of the apparatus main body 1 is considered to be positioned below the overhead line K in order to improve the stability of the apparatus main body 1 in a state where the traveling rollers 3 and 3 are placed on the overhead line K. Has been.

  The distance between the front and rear traveling rollers 3 and 3 is considered to be a necessary distance for achieving the traveling stability of the apparatus body 1. Since the front and rear traveling rollers 3 and 3 have the same structure, one traveling roller 3 will be described, and the other traveling roller 3 is assigned the same reference numeral.

  As shown in FIGS. 1 to 4, the traveling roller 3 includes a pair of left and right unit rollers 31, 31 that are spaced apart from each other with the overhead line K at the center. The outer peripheral surfaces of both unit rollers 31 and 31 are formed into curved surfaces (convex curved surfaces) whose roller diameters become smaller toward the opposite end portions. Further, the distance between the unit rollers 31 and 31 is set smaller than the diameter of the overhead wire K. Therefore, the traveling roller 3 is formed so as to have contact surfaces 3a and 3a that are in contact with the surface of the overhead wire K at two points while being placed on the overhead wire K.

  The unit rollers 31 and 31 are separately manufactured from polyacetal or the like, and are integrally and coaxially connected via a connecting cylinder 32. That is, the traveling roller 3 has a connecting cylinder 32 that coaxially connects the unit rollers 31, 31, and a roller rotating shaft 33 that passes through the connecting cylinder 32 in the axial direction and is fixed to the support frame 4 at both ends. ing. Bolts and nuts are used for the roller rotation shaft 33.

  The reason why the traveling roller 3 is configured in this manner is that the left and right unit rollers 31 and 31 formed as separate members can be integrated by the connecting cylinder 32, and the productivity of the traveling roller 3 itself can be improved. is there. Further, it is possible to easily replace with another unit roller whose outer peripheral surface shape is changed according to the size and shape of the overhead wire K.

The support frame 4 is made of aluminum (resin or other metal may be used), and the plate members 41 and 41 disposed on both sides (outside) of the traveling rollers 3 and 3 are connected to connect both plate members 41 and 41. The material 42 is provided. The connecting member 42 is bent upward in an inverted U shape, and a hanging metal fitting 43 is provided at the center of the upper surface thereof. The suspension fitting 43 is located on the center of gravity of the apparatus main body 1. The hanging metal fitting 43 is provided so that the apparatus main body 1 can be lifted in a stable state by a hook provided at the tip of an insulating rod or the like (not shown) and can be easily placed on the overhead wire K.

  The hanging member 5 extending from the support frame 4 has a band plate shape and is arranged so as to hang downward from both sides of the front and rear traveling rollers 3 and 3. In this embodiment, each drooping member 5 is fixed to brackets 44 provided on plate members 41 on both sides of the support frame 4 as shown in FIG. Each of the hanging members 5 is formed in a pair symmetrically with the overhead line K as the center, and two pairs in front and rear are arranged. Furthermore, each drooping member 5 has an arc shape as a whole when viewed from the front side as shown in FIG. 2, and is formed such that its curved portion extends left and right.

  Then, the pair of left and right hanging members 5 and 5 are formed so as to have an interval portion α that is larger than the protruding length of a projection such as a damper or a ring provided on the overhead wire K. This is to make it possible to smoothly pass projections such as dampers and rings on the overhead line K as they are using the space α between the left and right hanging members 5 and 5.

  Further, in order to prevent protrusions and the like on the overhead line K from entering between the traveling rollers 3 and 3, the support frame 4 between the traveling rollers 3 and 3 is positioned above the overhead line K. A bottom cover 7 is provided.

  A pair of drooping members 5 and 5 arranged symmetrically in the left-right direction are provided in two pairs in total, with a distance in the longitudinal direction of the overhead wire K. The cutting blade 6 is a device for each drooping member 5. It is provided at each of the edge portions corresponding to one and the other (the front-rear direction) of the moving direction of the main body 1. That is, each strip member 5 has edge portions extending downward on both sides thereof, but the cutting blade 6 is provided on one edge portion. Therefore, the cutting blade 6 is not provided in the edge part which opposes in the running direction of the apparatus main body 1 among the edge parts of each drooping member 5.

  These cutting blades 6 can also be provided integrally with each hanging member 5, but in this embodiment, in order to make only the cutting blade 6 replaceable, what is manufactured as a separate member is used as the edge portion of the hanging member 5. It is configured to be installed.

  Four cable members 2 for operating the apparatus main body 1 are used, and their end portions are connected to the lower ends of the hanging members 5 via connection fittings 8 such as ring shackles. By connecting one end of the rope member 2 to the lower end of the drooping member 5, it is possible to have a form that continues from the lower end of the drooping member 5 to one end of the rope member. Thereby, both the operation | work which makes the apparatus main body 1 detach | leave from the overhead line K using the rope member 2, and can mount | wear on the overhead line K can be performed smoothly.

  The plate members 41 and 41 on both sides constituting the support frame 4 of the apparatus main body 1 are provided with handles 9 and 9 in consideration of carrying of the apparatus main body 1.

  A method of using the flying object removing device configured as described above will be described below. There are two methods for mounting the apparatus main body 1 on the overhead wire K. One of them is suitable when the overhead height of the overhead line K is relatively low. As shown in FIG. 5A, first, two of the four cable members 2 are overhead. The other two rope members 2 are successively fed out while the two rope members 2 passed over the line K are pulled over to the opposite side. Then, the apparatus main body 1 smoothly transitions from the state shown in FIG. 5A to the attached state shown in FIG.

When the apparatus main body 1 is separated from the overhead line K and collected, an operation reverse to the above may be performed.
As described above, it is possible to smoothly perform the work of removing the apparatus main body 1 from the overhead line K by using the cable member 2 and the work of mounting on the overhead line K.

  Another method is a method of using the hanging metal fitting 43 when the overhead line K is considerably high from the ground like a high-voltage power transmission line. For example, on the steel tower, the hook provided at the tip of an insulating operation rod (not shown) can be hooked on the hanging metal fitting 43, lifted, and placed on the overhead wire K. In the past, due to structural problems of the equipment itself, it was impossible to clear the protrusions such as dampers and pass through them, so a rope from above the steel tower was placed at a position where equipment several meters from the steel tower could be installed. After guiding the rope to the throwing ground, connecting the rope and the device body on the ground, it was set on the overhead line while operating the rope from the ground. However, since the apparatus main body 1 according to the embodiment can pass through the protrusions, it can be attached to an overhead line near the feet where the worker is located, and the workability is remarkably improved. Can do. Further, by using an insulating operation rod, the apparatus main body 1 can be mounted even when the overhead wire is in a live line (charged) state.

  As described above, when the apparatus main body 1 is mounted on the overhead line K by any method (see FIG. 6), the two cable members on the front side in the traveling direction indicated by the arrow A among the two cable members 2 in front and rear. 2 is operated by one worker, the other two rope members 2 are operated by another worker, and the apparatus main body 1 travels in the direction of arrow A, thereby cutting the flying object 10 on the front side. It can be cut and removed with the blade 6.

  In this operation, when it is difficult to cut the flying object 10, the flying object 10 can be reciprocated and cut by the rear cutting blade 6. Further, since the apparatus main body 1 has sufficient stability due to its low center of gravity, the object main body 1 is tilted to the left or right (slightly rotated around the axis of the overhead line K) and reciprocally traveled. A method of cutting 10 can also be employed. The operation for lowering the apparatus main body 1 from the overhead line K can be performed by operating the rope member 2 regardless of the height of the overhead line K.

  According to this embodiment, each traveling roller 3 has the contact surfaces 3a and 3a that are in contact with the surface of the overhead line K in a state of being placed on the overhead line K. The contact area of each traveling roller 3 with respect to the overhead line K is substantially larger than that in contact with one point. Further, the traveling rollers 3 are arranged in parallel in the longitudinal direction of the overhead wire. Thereby, the apparatus main body 1 can run stably along the overhead line without meandering on the overhead line K.

  Further, the position of the center of gravity of the apparatus main body 1 has a low center of gravity because each traveling roller 3 is positioned below the overhead line K in a state where the traveling rollers 3 are placed on the overhead line K. From this point, the stability of the apparatus body 1 is also stable. The running function can be enhanced. Thereby, the operativity of the apparatus main body 1 using the rope member 2, the removal function of the flying object 10, etc. are improved significantly.

  As a result, it is possible to greatly reduce the labor, the number of workers, the work time, etc., for the flying object removal work, and when the overhead line 1 is a power transmission line, the power transmission line stop time is greatly shortened. Can do. Alternatively, the flying object removal operation can be performed even in a live line state.
