Description

  TECHNICAL FIELD The present invention relates to a utility pole lifting rope for use in raising and lowering a utility pole.

  Conventionally, a step for raising and lowering a power pole has been provided. A plurality of such steps are provided on the left and right sides in the radial direction of the utility pole at predetermined intervals in the height direction of the utility pole. The plurality of steps on the left and right sides are alternately arranged in the height direction of the utility pole. In other words, each step is provided in an arrangement suitable for the positions of the hands and feet of the worker who raises and lowers the utility pole, so as to improve the convenience of the worker who raises and lowers the utility pole.

  By the way, if a plurality of steps can be arranged over the entire length of the utility pole, the operator can move up and down with respect to the utility pole as it is. In general, steps are not arranged within a predetermined height range.

  For this reason, the worker performs the ascending / descending operation with respect to the utility pole so as to rise to a predetermined height by the ladder and transfer to the lowest step.

  However, if a ladder is required for raising and lowering the utility pole as described above, the worker must always carry the ladder, and there is a problem that the work load on the worker increases. In particular, in an area where it is difficult to enter a car such as a mountainous area, an operator must move a long distance with a ladder, and the work load becomes great.

  Then, this invention makes it a subject to provide the electric pole raising / lowering rope ladder which is easy to carry and can raise / lower an electric pole smoothly in view of such a situation.

  The electric pole raising and lowering rope ladder according to the present invention has a plurality of steps attached at predetermined intervals from the predetermined height on the left and right sides, and at least the left and right steps on the lower side are alternately arranged in the height direction. On the other hand, it is a power pole lifting rope used when a worker ascends and descends, a pair of left and right hanging ropes hanging from the left and right side steps, and both ends connected to a pair of hanging ropes, the hanging rope part Two or more step rope portions provided at intervals in the longitudinal direction of the pair, and the pair of hanging rope portions are provided with latching means for latching the step at each one end, and each latching means In order to correspond to the arrangement of the left and right steps, one end side of one hanging rope portion is formed to extend beyond one end of the other hanging rope portion, and both ends of each step rope portion are drooping at the tip. On the other end of the rope Characterized in that it is connected to the hanging under rope portion in a state along the lower rope portion. Here, the term “rope” includes a rope made by twisting plant fibers such as palm and hemp, a rope made by twisting synthetic fibers, and a rope made by twisting plant fibers and synthetic fibers. It is a concept.

  According to the rope raising and lowering rope ladder having the above configuration, the pair of hanging rope portions and the two or more step rope portions are constituted by ropes, so that each can be deformed and compact when not in use. Convenient to carry. In addition, the pair of hanging rope portions is provided with a latching means for latching the step on each end, and one hanging side of one hanging rope portion is on the other side so that each latching means corresponds to the arrangement of the left and right steps. Since it is formed so as to extend from one end of the hanging rope part, even if the arrangement of the steps on the left and right sides attached to the utility pole is different in the height direction of the utility pole, at the other end side of each hanging rope part The position of each step rope connected to the pair of hanging ropes can be in an appropriate state without being displaced.

  Furthermore, since both ends of each step rope are connected to the hanging rope with the tip at the other end of the hanging rope and along the hanging rope, the operator can attach the electric pole lifting rope ladder. When going up, it is possible to smoothly step on each step rope. In other words, when the part where the operator puts his foot is composed of a straight bar, or when the step rope part is provided so as to be substantially orthogonal to each hanging rope part, the pair of hanging rope parts are suspended from the step. The part of the foot that comes into contact with the utility pole makes it impossible for the operator to put on the foot. However, the step rope portion of the electric pole lifting rope ladder according to the present invention has both ends connected to the hanging rope portion in a state along the hanging rope portion with the tip at the other end side of the hanging rope portion. The center side is located above the part, and with the pair of hanging ropes hooked to the step, the step rope part falls down due to its own weight or contact with the utility pole, etc. It becomes. Therefore, the operator can easily put his / her feet on the step rope portion and can move up and down smoothly.

  And as 1 aspect of this invention, the holder formed in the cylinder shape may be externally fitted by the said step rope part. If it does in this way, rigidity can be given to at least one part of a step rope part by existence of a maintenance object, and an operator can make it easy to put a foot.

  Furthermore, as another aspect of the present invention, a winding means that can be wound around the utility pole is further provided, and an insertion portion through which the winding means is inserted is provided at each other end of the pair of hanging rope portions. Also good. If it does in this way, movement of the lower end part of the hanging rope part (electric pole raising and lowering rope ladder) suspended from the step is regulated by winding the winding means around the electric pole in a state where the winding means is inserted, and the operator moves up and down. It is possible to make it easy to do.

  As described above, according to the rope ladder for raising and lowering the utility pole of the present invention, it is possible to achieve an excellent effect that it is easy to carry and the elevator pole can be smoothly raised and lowered.

SR on the left and right sides of the utility pole P. It is comprised so that the side may extend rather than the end of the other hanging rope part 10b.

  The latching means 12a, 12b according to the present embodiment is formed such that one end of the hanging rope portions 10a, 10b is a ring. That is, each latching means 12a, 12b bends one end side of the hanging rope portions 10a, 10b into a substantially U shape and connects the end portion to the other end portion of the hanging rope portions 10a, 10b. It is formed in an annular shape. In addition, about the connection method of the edge part with respect to the part of the other end side of hanging rope part 10a, 10b, the connection method of the step rope part 11 ... with respect to hanging rope part 10a, 10b, and the preparation methods of the insertion parts 13a, 13b mentioned later In addition, the details will be described later.

  The electric pole raising and lowering rope ladder 1 according to the present embodiment is provided with insertion portions (hereinafter referred to as belt insertion portions) 13a and 13b for inserting the winding means 15 into the other end portions of the hanging rope portions 10a and 10b. . The belt insertion portions 13a and 13b of the present embodiment are formed by looping the same ropes as the hanging rope portions 10a and 10b. In this embodiment, since the pair of hanging rope portions 10a and 10b are formed by bending one rope into a U shape, the belt insertion portions 13a and 13b are defined as the hanging rope portions 10a and 10b. After being formed as a separate body, it is connected to the other end of each hanging rope portion 10a, 10b.

  The step rope portions 11 are also formed of the same ropes as the hanging rope portions 10a and 10b. And each step rope part 11 ... has one end connected to one hanging rope part 10a and the other end connected to the other hanging rope part 10b, so that a pair of hanging rope parts 10a, It has an aspect that spans 10b. Here, the characteristic part of the present embodiment will be described. Both end portions of each step rope portion 11 are lower in a state in which the tip is hooked to the other end side of the hanging rope portions 10a, 10b (steps SL, SR, ...). Is connected to the hanging rope portions 10a and 10b in a state along the hanging rope portions 10a and 10b. That is, the end portion of each step rope portion 11 is directed to one end side of the hanging rope portions 10a and 10b from the both ends toward the center side (the end portion side that is on the upper side in a state of being hooked on the steps SL. It is connected to the hanging rope portions 10a and 10b so as to extend.

  Therefore, the utility pole elevating rope ladder is in a normal state (a state where it is not hooked to the steps SL ..., SR ...), and the central portion of the step rope portion 11 ... is one end side of the hanging rope portions 10a, 10b rather than its end portion. It is supposed to be in a posture that collapsed. Thus, when the pair of hooking means 12a, 12b are hooked on the left and right steps SL ..., SR ... and the hanging rope portions 10a, 10b are suspended from the steps SL ..., SR ..., the step rope portions 11 ... It is designed to be in a mode in which an operator's foot is easily placed away from the utility pole P. That is, when the pair of hanging rope portions 10a, 10b is suspended from the steps SL ..., SR ..., the center of the step rope portions 11 ... is the fulcrum of the connection portion with the hanging rope portions 10a, 10b by contact with its own weight or the utility pole P. The ropes 10a and 10b tend to fall down to the other end side, but the step ropes 11 are maintained in a posture in the middle of falling without reaching the posture of the ropes 11 (the rope itself). 11... Is in a state where the central portion (portion where the foot is placed) is away from the utility pole P, that is, the state where the foot is easily placed (see FIG. 4B).

  Furthermore, in this embodiment, the length of each step rope portion 11 is set to be shorter as it is located on the other end side of the hanging rope portions 10a and 10b. That is, the pair of hanging rope portions 10a and 10b hanging from the steps SL... SR on the left and right sides of the electric pole P are inclined in a direction intersecting the axis of the steps SL. Each step rope portion 11... Is in a state inclined between the pair of suspended rope portions 10 a and 10 b around the outer periphery of the utility pole P in consideration of the state. The length corresponding to the distance is set. As a result, when the operator puts his or her foot on after forming a minimum gap between the step rope 11 and the utility pole P so that the operator can put his foot on the step rope 11 and so on. The step rope portions 11 can be prevented from drooping downward more than necessary.

  The holding body 14 is for maintaining the portion of the step rope portions 11... To be applied in an appropriate posture. In this embodiment, the holding body 14 is used to prevent weight increase and to deform the step rope portions 11. From a viewpoint, it is comprised with the tube which has flexibility, such as resin and rubber | gum. The holding body 14 is externally fitted to the step rope portions 11 before connecting the step rope portions 11 to the hanging rope portions 10a and 10b, and the holding rope 14 is externally fitted to the step rope portions 11. In this state, it is connected to the hanging rope portions 10a and 10b.

  The winding means 15 includes a belt 15a having a length equal to or greater than the outer peripheral length of the base end portion of the utility pole P, and a buckle 15b provided at one end portion of the belt 15a. The buckle 15b is configured to allow the belt 15a to be inserted therethrough and to be able to lock the inserted belt 15a. As a result, the winding means 15 can fasten and fix the electric pole P in a state where the belt body is wound around the electric pole P.

  Next, a description will be given of a method of connecting the ropes used for making the hooking means 12a, 12b and the belt insertion portions 13a, 13b and connecting the hanging rope portions 10a, 10b and the step rope portions 11. Here, as shown in FIG. 3, three ropes (hereinafter referred to as fine ropes) R1, R2, and R3 are formed on each of the connected rope A and the connected rope B, respectively. For example, the connected side A rope is referred to as a parent rope, and the connected side rope B is referred to as a child rope. Also, in the figure, from bottom to top, the fine rope R1 without hatching is the first fine rope, the fine rope R2 with diagonal hatching is the second fine rope, and the fine rope with vertical hatching. R3 is referred to as a third fine rope, and the fine rope corresponding between the parent rope A and the child rope B is given the same name and the same reference numeral.

  First, unravel the tip of the child rope B, put it in the state of three fine ropes (first fine rope R1, second fine rope R2, third fine rope R3) and put tape etc. This prevents the fine ropes R1, R2, and R3 from being unraveled. Thereafter, the second fine rope R2 of the child rope B is passed under the third fine rope R3 of the parent rope A, and the first fine rope R1 of the child rope B is held by holding the third fine rope R3 of the parent rope A. Pass under the first fine rope R1 of A.

  Then, the parent rope A and the child rope B are rotated 180 ° (inverted horizontally in the figure) to find the second fine rope R2 of the parent rope A, and the first and second fine ropes R1, R2 of the child rope B are In the same direction, the third fine rope R3 of the child rope B is passed under the second fine rope R2 of the parent rope A. In this state, the first to third fine ropes R1, R2 and R3 of the child rope B come out from the parent rope A in three directions, and are tightened one by one. This process is called “satsuma insertion”, and the parent rope A and the child rope B are connected by repeating this process (satsuma insertion) three or more times.

  Therefore, the latching means 12a, 12b is formed by bending the end portions of the hanging rope portions 10a, 10b so as to form a ring with the hanging rope portions 10a, 10b, and the end portion side folded back as the child rope B is connected to the end portion. It is formed by being inserted into a portion (the hanging rope portions 10a and 10b) as the opposing parent rope A by satsuma. Further, the belt insertion portions 13a and 13b are formed by inserting a short rope into a ring and inserting one end portion as a child rope B into the other end portion side as a parent rope A, and The other end as the child rope B is connected to the hanging ropes 10a and 10b by inserting the other end into the hanging ropes 10a and 10b as the parent rope A.

  And in connection of the step rope part 11 ... to the hanging rope part 10a, 10b, the end part of the step rope part 11 ... as the child rope B is connected to the hanging rope part 10a, 10b as the parent rope A. The step rope portions 11 are connected to the hanging rope portions 10a and 10b by inserting the portions 10a and 10b from one end side to the other end side.

  Therefore, the main structure of the utility pole raising and lowering rope ladder 1 according to the present embodiment is formed of a single material, and can be bent as a whole.

  The utility pole elevating rope ladder 1 according to the present embodiment has the above-described configuration. With reference to FIGS. 4A and 4B, a usage mode of the utility pole elevating rope ladder 1 will be described first. The hooking means 12a, 12b formed at one end of the rope portions 10a, 10b are hooked on the steps SL ..., SR ... of the utility pole P. That is, each latching means 12a, 12b is latched to steps SL ..., SR ... of the utility pole P via an indirect hot wire tool, a bar, or the like. Then, the utility pole raising and lowering rope ladder 1 according to the present embodiment is provided at positions where the respective latching means 12a and 12b are shifted in accordance with the height-direction intervals of the left and right steps SL... SR. Even if it hangs down to steps SL ..., SR ... which are alternately arranged on both the left and right sides, the lower ends (other end portions) of the hanging rope portions 10a, 10b are positioned at substantially the same height, and the step rope portions 11 The two ends of... Are substantially corresponding positions in the height direction.

  Then, after the belt 15a is inserted into the belt insertion portions 13a and 13b, the winding means 15 is wound and fixed around the base portion of the utility pole P to prevent the lower end of the utility pole lifting rope ladder 1 from shaking.

  When the utility pole elevating rope ladder 1 is attached in this manner, the step rope portions 11... Fall down to a certain posture as described above, and the central portion (holding body 14) of the step rope portions 11. A gap for positioning the toe is formed between the rope portion 11 (the holding body 14) and the utility pole P. Therefore, it becomes easy to put a foot on the step rope portions 11 (holding body 14), and the operator can smoothly move up and down.

  As described above, the utility pole raising and lowering rope ladder 1 according to the present embodiment has a pair of hanging rope portions 10a and 10b and two or more step rope portions 11... It is flexible and can be compact when not in use, making it easy to carry around. The pair of hanging rope portions 10a, 10b are provided with hooking means 12a, 12b for hooking the step SL ..., SR ... at each end, and the hooking means 12a, 12b are connected to the left and right steps SL ... In order to correspond to the arrangement of SR ..., one end side of one hanging rope part 10a, 10b is formed to extend from one end of the other hanging rope part 10a, 10b, so the left and right attached to the utility pole P Even if the arrangement of the steps SL... SR on the both sides is different in the height direction of the utility pole P, it is possible to obtain an appropriate arrangement state without the step rope portions 11.

  Further, both end portions of each step rope portion 11 are connected to the hanging rope portions 10a, 10b in a state along the hanging rope portions 10a, 10b with the tip at the other end side of the hanging rope portions 10a, 10b. Therefore, when an operator goes up the rope pole 1 for raising and lowering the electric pole, the step rope portions 11 can be smoothly put on.

  And since the holding body 14 formed in the cylindrical shape is externally fitted to the step rope portions 11..., At least a part of the step rope portions 11. It is possible to make it easy for an operator to set foot.

  Furthermore, the winding means 15 that can be wound around the electric pole P is provided, and the belt insertion portions 13a and 13b that allow the belt 15a to be inserted into the other end portions of the pair of hanging rope portions 10a and 10b are provided. Therefore, the movement of the lower end part of the electric pole raising and lowering rope ladder 1 can be restricted, and the operator can smoothly move up and down.

  In addition, the electric pole raising / lowering rope ladder of this invention is not limited to the said embodiment, Of course, various changes can be added in the range which does not deviate from the summary of this invention.

  In the above-described embodiment, the holding body 14 that is externally fitted to the step rope portions 11 is provided. However, the present invention is not limited to this. For example, the feet are directly attached to the step rope portions 11 without providing the holding body 14. It may be configured to apply. However, it is needless to say that it is preferable to provide the holding body 14 in consideration of the stability when the operator puts his / her foot. Moreover, when providing the holding body 14, the holding body 14 is not limited to a cylindrical thing, For example, you may make it employ | adopt the cylindrical body which makes a cross-sectional polygonal shape in the holding body 14. FIG. In this way, since a plurality of ridge lines extending in the axial direction of the holding body 14 are formed in the circumferential direction, the ridge lines serve as a slip stopper. Therefore, safety can be ensured even if the outer peripheral surface of the holding body 14 is not slip-prevented.

  In the above embodiment, the hooking means 12a, 12b for hooking to the steps SL ..., SR ... of the utility pole P are formed with one end of the hanging ropes 10a, 10b as a ring, but this is not limitative. For example, a metal hook may be provided at one end of the hanging rope portions 10a and 10b, and the hooking means 12a and 12b may be configured by the hooks. When the latching means 12a and 12b are made of metal hooks, the latching means 12a and 12b are not necessarily formed in a ring shape, as long as they can be latched on the steps SL... SR. Good. However, when attaching the hook, the end portions of the hanging rope portions 10a and 10b (portions through which the hook is inserted) must be formed like a ring. Therefore, it is necessary to form the latching means 12a, 12b at one end of the hanging rope portions 10a, 10b without providing a hook from the viewpoint of cost and compactness of the electric pole lifting rope ladder 1 as well. It is valid.

  In the above embodiment, the pair of hanging rope portions 10a and 10b is formed by bending one rope into a U shape. However, the present invention is not limited to this, and for example, a pair of hanging rope portions 10a. , 10b may be composed of independent ropes. Also in this case, one end of each of the pair of hanging rope portions 10a and 10b is shifted corresponding to the distance between the left and right steps SL ..., SR ... provided on the utility pole P, that is, one hanging rope portion 10a. Of course, one end of the other hanging rope part 10a, 10b extends from one end of the terminal 10b.

  Furthermore, in the said embodiment, while inserting the insertion parts 13a and 13b in the lower end part of the hanging rope parts 10a and 10b, it is provided so that the winding means 15 inserted in the insertion parts 13a and 13b and wound around the utility pole P may be provided. However, it is not limited to this, The insertion parts 13a and 13b and the winding means 15 should just be provided as needed. However, since the electric pole raising and lowering rope ladder 1 is entirely constituted by a rope and there is a high possibility that shaking will occur during raising and lowering, it is preferable to perform the same as in the above embodiment.

  When the winding means 15 is provided, the winding means 15 is not limited to the one provided with the belt 15a and the buckle 15b. For example, the winding means 15 is similar to the hanging rope portions 10a and 10b. Of course, it may be configured by a rope. Moreover, about the insertion parts 13a and 13b, it is not limited to what was comprised with the rope, For example, you may make it comprise the insertion parts 13a and 13b with metal rings and hooks. However, as with the latching means 12a and 12b, if the insertion portions 13a and 13b are made of another member such as metal or resin, the portions cannot be deformed, and the cost increases with an increase in mounting work and parts. Since there exists a possibility, it is preferable to set it as the same structure as the said embodiment.

  In the above embodiment, the utility pole elevating rope ladder 1 is hooked to the steps SL..., SR using an indirect hot wire tool or a bar, but for example, the hooking means 12a, 12b and the uppermost step rope portion. For example, a flexible resin tube is externally fitted to the hanging rope portions 10a and 10b between 11 and the like, and the latching means 12a and 12b at the tip are stepped by holding the resin tube. You may make it latch on SL ..., SR .... That is, when only the hanging rope portions 10a and 10b are gripped and the latching means 12a and 12b are latched at the upper steps SL, SR, etc., the hanging rope portions 10a and 10b are deformed and the latching means. 12a, 12b cannot be directly hooked to the steps SL ..., SR ..., but if the resin tube as described above is externally fitted, the rigidity can be slightly increased. It is possible to prevent bending in a short time such that 12b is hooked to steps SL... SR. Therefore, the latching means 12a and 12b can be latched to the steps SL. If the resin tube is made flexible as described above, it can be bent when not in use, and it is possible to prevent the compacting of the electric pole lifting rope ladder 1 from being hindered.

  In the above embodiment, the connection of the step rope portions 11... To the hanging rope portions 10a and 10b, the production of the hooking means 12a and 12b, and the insertion portions 13a and 13b are performed by weaving ropes (satsuma insertion). However, the present invention is not limited to this. For example, the ropes may be sewn and connected, or the ropes may be connected by other braiding methods.
