Description

  The present invention accommodates two electric wires on both sides when widening the interval between the two electric wires on both sides adjacent to the electric wire to be cut, for example, in a work for separating a plurality of overhead wires arranged in parallel. The present invention relates to an electric wire container to be held and a widening tool including the same.

  In order to minimize the impact on power consumers, electric cables are often cut off using a bypass cable in an uninterrupted state. In this case, it is necessary to create a situation in which the interval between the plurality of overhead wires arranged in parallel is widened so that the cutting tool can be easily and safely attached and detached.

  Therefore, conventionally, for example, when widening a parallel overhead wire such as a triangular pillar wiring, an overhead wire widening tool as shown in FIG. 6 has been used.

  Here, three overhead lines 100 are shown which are parallel to each other, two in a substantially horizontal state on the upper side and one on the lower side. In FIG. 6, the state before widening is indicated by a solid line, and the state after widening is indicated by a virtual line. The overhead wire widening tool 101 is composed of two widening widening rods 102 and widening vertical rods 103 that can be expanded and contracted in an orthogonal arrangement. An end of each of the widening horizontal rod 102 and the widening vertical rod 103 is provided with an overhead wire gripping tool 104 for gripping the overhead wire 100. The overhead wire gripping tool 104 has a structure that can be gripped by sandwiching the overhead wire 100 between a slider 106 that is moved by a drive screw 105 and a concave side wall 107. With such a configuration, the interval between the three overhead wires 100 can be increased, so that a widened state in which mutual interference can be avoided can be satisfactorily maintained and work can be performed safely.

  Such an overhead wire widening tool is described in Patent Document 1.

  As another form, an overhead wire widening tool as shown in FIG. 7 is also known. This overhead wire widening tool 201 is used to widen the interval between the three overhead wires 200 arranged in parallel in substantially the same plane.

  The overhead wire widening tool 201 shown here grips the central middle line 200a among the three by the middle line gripping member 203 provided at the center of the main body rod 202. Next, in a state where the main body rod 202 is fixed to the middle line 200a in this way, the main body rod 202 is tilted, and the height positions of the rollers 204 provided at the upper and lower ends of the main body rod 202 are adjusted to the positions of the upper and lower overhead lines 200. . Then, the upper and lower overhead lines 200 are placed on the respective rollers 204. When the main body rod 202 is raised in this state, the roller 204 is erected while sliding on the upper and lower overhead lines 200, and the upper and lower overhead lines 200 are separated. And the space | interval of the overhead wires 200 spreads, the lower body wire 200 is clamped between the roller 204 and the overhead wire pressing member 205 in a state where the main body rod 202 and the overhead wire 200 are substantially orthogonal, and the overhead wire widening tool 201 is It is fixed to the overhead line 200.

  Such an overhead wire widening tool is described in Patent Document 2.

  However, in the overhead wire widening tools 101 and 201 shown in FIGS. 6 and 7, the overhead wires 100 and 200 whose intervals are widened are respectively clamped by the clamping members (the overhead wire gripping tool 104 and the overhead wire pressing member 205). Yes.

  For this reason, when a longitudinal force (such as tension generated on the overhead wire) is applied to the sandwiched overhead wires 100 and 200, the influence is directly transmitted to the overhead wire widening tools 101 and 201 via the sandwiching member.

  In other words, when the overhead wires 100 and 200 are displaced in the longitudinal direction during construction, the overhead wires 100 and 200 are pulled by the overhead wires 100 and 200, so that the angles at which the overhead wire widening tools 101 and 201 are disposed are inclined.

  In addition, since the restoring force works from the overhead line 100 and the overhead line 200 in the widened state toward the original positions parallel to each other, the overhead wire widening tools 101 and 201 holding these in the widened state have the overhead wires on both sides. The force is acting in the direction of being compressed between 100 and 200.

  That is, in the state where the force based on the restoring force of the overhead wires 100 and 200 is working from both sides of the overhead wire widening tools 101 and 201, tension is applied in the longitudinal direction of the overhead wires 100 and 200, and the arrangement angle of the overhead wire widening tools 101 and 201 If a tilt occurs, this tilt is easily promoted. As a result, there is a possibility that the interval between the overhead wires 100 or 200 widened for work is narrowed.

  Moreover, since it is necessary to reinforce each part when it is going to implement | achieve the structure which can endure any force from the overhead wire 100 or 200 so that the position shift to the longitudinal direction of such an overhead wire 100 or 200 may not be caused, Each member increases in size, and as a result, increases in weight.

  Further, in order to firmly fix the overhead wire 100 or 200, the above-described gripping structure by screw fastening (the drive screw 105 and the overhead wire pressing member 205) is suitable. However, the more firmly fixed, the clamping member becomes the overhead wire 100. Or, since it is easy to adhere to 200 and it takes time to perform the rotation operation using the remote control rod, the work efficiency is not good.

  As shown below, an electric wire holder or an overhead wire widening tool equipped with an electric wire container that holds the electric wire in a sandwiched state is easily affected by the deviation of the electric wire in the axial direction, which may cause danger to the operator or increase the work efficiency. May decrease.

  Then, in order to solve the said subject, in this invention, it aims at providing the electric wire container which can reduce the influence of the position shift to the axial direction of the electric wire accommodated and hold | maintained, and the widening tool using the same. .

  In order to achieve the above object, an electric wire container according to the present invention is based on a hook portion that extends in a substantially U shape and has an electric wire holding area formed inside, and on one side of two free ends of the hook portion. The end is pivotally supported and can swing to the inside of the storage area, and the swing end can extend to the other side of the free end to close the storage area. And a closure that can prevent the outward rotation, the closure having at least one joint, and the joint is in a position where the accommodation area of the closure is closed. On the other hand, it can be bent only inward of the housing area.

In addition to the above configuration, the wire container of the present invention includes a base end biasing means for biasing from one side of the free end to the base end, and outward from the storage area, and a base end to a swing end. And a joint urging means for urging the joint in the extending direction.

  In addition to the above configuration, the wire container of the present invention is characterized in that the urging force of the proximal urging means is larger than the urging force of the joint urging means.

  Further, in addition to the above configuration, the wire container of the present invention includes a protrusion that can protrude on the rotation track of the base end outward from the state in which the closing tool closes the storage area, and a protrusion. It is characterized by comprising a switching means capable of switching between a state of projecting on a rotation trajectory outward of the base end and a retracted state.

  Moreover, in addition to the above configuration, the wire container of the present invention has a swinging portion capable of swinging about the extending direction of the free end on one side of the free end, and the base end is It is characterized by being pivotally supported by the swing part.

  Moreover, the widening tool of this invention is a widening tool which widens the space | interval of the three electric wires laid in parallel in the substantially same plane, Comprising: The expansion-contraction bar | bowl which can be expanded-contracted in a longitudinal direction, and the approximate center of an expansion-contraction bar | burr And an electric wire gripper for gripping the electric wire located in the center of the three, and the electric wire container for accommodating electric wires on both outer sides of the three is provided at both ends of the telescopic rod. And

  Moreover, the electric wire container of the widening tool of the present invention is characterized in that the extending direction of both free ends is provided in the extending direction of the telescopic rod.

  As described above, according to the present invention, the closing tool that has received a force inward of the accommodation area allows the inward rotation of the accommodation area at the shaft support portion of the proximal end, and the joint. Further, the swinging portion at the tip is allowed to turn to the inner side of the receiving area with respect to the base end. Further, the joint does not allow the swinging end to rotate outwardly of the housing area with respect to the closing tool which is in the position where the housing area is closed and is prevented from rotating outward.

  As a result, the electric wire can be flexibly received by pressing the closing tool from the outside to the inside, while the electric wire housed in the housing area presses the closing tool from the inside to the outside. In addition, in the closing device in which the rotation to the outside of the accommodation area is suppressed, in addition to the suppression action, the joint portion also does not rotate outward, so that a good electric wire state can be maintained. And in an accommodation state, since an electric wire is not pinched | interposed into a closing tool etc. and is loosely fitted in the accommodation area surrounded by the U-shape, even if tension is applied in the longitudinal direction of the electric wire, the electric wire The influence of the tension does not occur on the container, and the posture of the wire container can be stabilized satisfactorily.

  Further, according to the present invention, the closing tool in a state in which the rotation to the outside of the housing area is restrained is outwardly biased from the free end to the base end, and from the base end to the swing end of the joint. Due to the outward urging of the container, the housing area is stabilized at the closed position. When an inward force is applied from the outside of the storage area, at least one of the entire closure and the swinging end of the storage area resists the biasing of the base end biasing means and the joint biasing means. It can be turned inward.

  Further, according to the present invention, since the biasing force of the joint biasing means is smaller than the biasing force of the proximal end biasing means, the base end rotates relative to the base end rather than rotating relative to the free end. It becomes easier for the swing end to rotate. Thereby, the electric wire smaller than the space | interval of a joint and a buttocks becomes evacuable because a joint bends.

  Moreover, according to this invention, it can switch to the state which protruded the protrusion part on the rotation track | orbit of the base end to the outward side from the state which closed the accommodation area of the closing tool, and the retracted state. Thereby, in the state in which the protruding portion is protruded, the electric wire can be accommodated by retracting the closing tool so as to bend inside the accommodation area against the urging force of the proximal end urging means and the joint urging means, After the accommodation, since the rotation of the closing tool to the outside is prevented, it is possible to prevent the wires from dropping out of the accommodation area. Then, when switching to the state in which the protruding portion is retracted by the switching means, the base end urged outward by the base end urging means is released, and the entire closing tool rotates to the outer side of the accommodation area. For this reason, the accommodating area is opened, and the electric wire can be easily detached from the accommodating area.

  In addition, according to the present invention, the closing tool can be rotated about the extending direction of the free end independently of the rotation of the base end relative to the free end and the rotation of the swing end relative to the base end. As a result, even if the closure is prevented from rotating outwardly of the accommodation area, the accommodation area can be greatly opened by swinging around the axis of the free end, and the wire can be easily taken out. become.

  Further, according to the present invention, when the electric wire is pressed against the closing tool of the electric wire container provided at both ends in a state where the central electric wire is gripped by the electric wire gripping portion among the three electric wires, the closing tool is inward. The electric wire is accommodated in the accommodating area.

  As a result, the holding state of the three electric wires can be easily and quickly formed simply by holding the central electric wire with the electric wire holding portion and pressing the electric wire against the closing tool, thereby improving work efficiency. .

  Further, according to the present invention, since the extending direction of both free ends is formed so as to face the extending direction of the telescopic rod, the opening side of the accommodation area of both U-shaped flanges is arranged outward in the extending direction. Has been. As a result, since the electric wire can be accommodated in the accommodating area by a simple operation of extending the telescopic rod, it is possible to improve the work efficiency, and further, from the electric wire at the time of expansion (when the electric wire is widened). Since the inner direction to which the reaction force is applied and the opening direction of the accommodation area are opposite to each other, it is possible to prevent the wires from falling off and to improve the safety of work.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
The electric wire container in the 1st Embodiment of this invention is demonstrated using FIGS. 1-3.

  FIG. 1: is the perspective view which showed the accommodation state of the electric wire about the electric wire container 1 which concerns on this invention. The wire container 1 shown in FIG. 1 extends so as to bridge between a flange portion 2 formed in a substantially U shape and two free ends 2a and 2b extending in the U shape of the flange portion 2. It comprises a closing tool 4. And the accommodating area 3 of the electric wire 30 is formed surrounded by the collar part 2 and the closing tool 4.

  The closing tool 4 is composed of two parts, a base end portion 4a and a retaining pin 4b (oscillating end). The base end portion 4a on the base end side is pivotally supported by one of the free ends 2a and 2b of the flange portion 2 on a support shaft 2c (described later with reference to FIG. 2) so as to be swingable. ing. Further, the retaining pin 4b is pivotally supported by the base end portion 4a so as to be swingable. Thus, the closing tool 4 is provided with a joint 4d that connects the base end portion 4a and the retaining pin 4b.

  Here, the base members 4a and the retaining pins 4b constituting the closing tool 4 are respectively described in the spring members 8 and 10 (to be described later with reference to FIG. 2) in the direction of rotation toward the outer side of the receiving area 3. ). As shown in FIG. 1, the position where the closing tool 4 extends so as to connect the free ends 2a and 2b is defined as the closed position of the receiving area 3, and the base end 4a is positioned in the receiving area 3 with respect to the closed position. It is pivotally supported on both the inner side and the outer side.

  A release ring 6 is provided at the free end 2a on which the base end portion 4a is pivotally supported. The release ring 6 is provided to form and release a locked state that prevents the base end portion 4a from rotating outward from the closed position. FIG. 1 shows a state in which a restriction is applied by the release ring 6, and it is impossible to rotate outward from the closed position, but outward to the spring member 8. If an external force larger than the urging force is applied, it can be rotated. Details of the restriction mechanism of the base end portion 4a by the release ring 6 will be described later with reference to FIGS.

  Further, the rotation range of the joint 4d is configured such that the retaining pin 4b cannot rotate outward from the base end portion 4a from the extended state as shown in FIG. If an external force larger than the urging force is applied, it can be turned only inward. Next, operations of the closing tool 4 and the release ring 6 will be described with reference to FIG.

  FIG. 2 shows a state in which the base end portion 4a and the retaining pin 4b are rotated inward of the accommodation area 3 against the urging force of the wire container 1 shown in FIG. Here, the periphery of the free end 2a is partially shown in a sectional view so that the regulating operation of the closing tool 4 by the release ring 6 can be understood well.

  Among these, FIG. 2A shows a state in which the closing tool 4 is rotated inward about the support shaft 2c by receiving a pressure from the electric wire 30 with which the base end portion 4a is in contact from the outside. ing. Further, FIG. 2B shows that the electric wire 30 slides on the inclined closing tool 4 and the object to be pressed by the electric wire 30 moves from the base end portion 4a to the retaining pin 4b, and then the outermost portion of the U-shaped accommodation area 3 is moved. The state which the electric wire 30 entered into the lower end is shown. Further, FIG. 2C shows a state in which the closing tool 4 is returned to the original closing position by the respective urging forces of the spring members 8 and 10 after the electric wire 30 enters the lowermost end.

  As can be seen from FIGS. 2 (a), (b) and (c), the base end portion 4a is formed with a stopper portion 7a so as to protrude radially around a support shaft 2c which pivotally supports the base end portion 4a. Has been. And the engagement pin 6a (projection part) is provided so that it can project or retract toward the rotation track | orbit of this stopper part 7a. Further, the engagement pin 6a is integrally provided with a release ring 6 (switching means) so that the position can be switched in the protruding and retracting directions, and by hooking a finger, a tool, or the like on the release ring 6. The engaging pin 6a can be protruded or retracted.

  FIG. 2 shows the release ring 6 in a state in which the engagement pin 6a protrudes on the rotation track of the stopper portion 7a.

  In FIG. 2A, the locus 12 drawn by the swing end 4c in a state where the joint 4d of the closing tool 4 is extended is indicated by a two-dot chain line. As can be seen from this, if the joint 4d is in the extended state, the remaining space of the accommodation area 3 excluding the space required for the rotation of the closing tool 4 has a very small area at the corner of the lower end (left side of the paper). .

  Therefore, in order to leave the accommodated electric wire 30 in the accommodation area 3 and return the closing tool 4 to the original closed position, the electric wire 30 to be targeted is placed in the gap on the bottom side of the accommodation area 3 with respect to the trajectory 12 described above. It must be thin enough to fit. That is, even if the opening of the accommodation area 3 is formed to be large, the upper limit of the outer diameter of the accommodated electric wire 30 is limited to a small value as long as the joint 4d of the closing tool 4 is extended.

  In order to solve this problem, a configuration having a so-called retracting portion in which a side portion of the flange portion 2, that is, a straight portion of the free end 2b is curved so as to protrude outward can be considered. In addition, a configuration in which the dimension in the depth direction of the storage area 3 is set to be larger than the reach area of the closing tool 4 and a retracting portion is provided in the depth direction can be considered.

  However, if the accommodation area 3 is expanded in the lateral direction or the depth direction in this way, it is necessary to make the entire flange part 2 surrounding the accommodation area 3 large, and the weight increases. When a member becomes large, there is a high possibility of interference with surrounding facilities, and the risk increases when working in an uninterruptible state. Also, the increase in weight makes handling difficult in remote operation. Therefore, although the collar part 2 must be formed as compact as possible, it is necessary to make the space required for the rotation of the closing tool 4 as small as possible. Therefore, the operation of reducing the rotation area of the closing tool 4 will be described with reference to FIGS.

  FIG. 2B shows a state in which the retaining pin 4b, which is a swinging portion that receives a pressure from the electric wire 30, is bent inward at the position of the joint 4d.

  Here, in the closing tool 4 in the present embodiment, the biasing force acting from the base end portion 4a toward the retaining pin 4b (swinging end) is more than the biasing force acting from the free end 2a toward the base end portion 4a. The strength is set to be smaller. For this reason, the spring member weaker than the spring member 8 (base end urging means) at the stage where the position of sliding contact with the closing tool 4 from the electric wire 30 is moved from the base end 4a to the retaining pin 4b. 10 (joint urging means) side is bent, and the joint 4d is bent inward of the accommodating area 3.

  Subsequently, FIG. 2C shows a state in which the closing tool 4 returns to the closed position where the outward rotation is suppressed by the biasing of the two spring members 8 and 10. Here, the locus 12 of the tip of the closure 4 shown in FIG. 2A is overlapped and indicated by a two-dot chain line. Similarly, a locus 14 indicated by a two-dot chain line indicates a rotation area of the distal end of the retaining pin 4b around the joint 4d in a state where the base end portion 4a is locked at the restriction position. As can be seen, by providing the joint 4d, the locus 14 of the tip of the closure 4 is lifted from the lower end side of the U-shaped accommodation area 3, and the rest of the accommodation area 3 excluding the rotation area of the closure 4 is removed. Space is getting wider.

Thus, when the biasing force of the spring member 10 is set to be smaller than the biasing force of the spring member 8, when the closing tool 4 pushed inward of the housing area 3 returns to the original closing position, When the retaining pin 4b comes into contact with the electric wire 30, the joint 4d is bent, and the spring member 8 having a strong biasing force operates to return to the original state before the spring member 10. Thereby, since the area | region which does not become the hindrance of rotation of the closing tool 4 can be taken widely among the storage areas 3, the collar part 2 can be formed small by the part which the allowance produced, and weight increase is suppressed. Thus, it is possible to reduce the risk of work.

  Next, the rotation operation | movement to the outward side of the closing tool 4 is demonstrated using FIG. As described above, the base end portion 4a can be selected by the release ring 6 between a state in which the rotation region is restricted and a state in which the base end portion 4a is released. FIG. 3A shows a state where the restriction is added, and FIG. 3B shows a state when the restriction is released. In FIG. 3, as in FIG. 2, the periphery of the free end 2a is partially shown in a sectional view for convenience of explanation.

  Here, when attention is paid to the notch 7 formed in the periphery of the support shaft 2c that pivotally supports the base end portion 4a, the width in the radial direction is shorter than the others, in FIG. The tip is in contact with the inside of the notch 7 and is in contact with a stopper portion 7 a that is a circumferential end position of the notch 7. As described above, in the state of FIG. 3A, the stopper portion 7a of the notch 7 and the distal end of the engagement pin 6a are in an engaged state, so that the base end portion 4a is further rotated outward. I can't move. In addition to this, since the urging force toward the outer side with respect to the free end 2a is acting on the base end portion 4a, the closing tool 4 is stabilized in the closed position.

  However, since the region of the notch 7 is widened in the circumferential direction opposite to the stopper portion 7 a in the peripheral edge of the support shaft 2 c, the base end portion is directed inwardly against the biasing by the spring member 8. The rotation of 4a is allowed.

  Accordingly, as shown in FIG. 3A, in the state where the base end portion 4a is restricted by the release ring 6, the electric wire 30 can be accommodated from the outside, and the accommodated electric wire 30 can be accommodated. The outward departure can be prevented.

  On the other hand, FIG. 3B shows a state in which the release ring 6 is pulled in a direction away from the flange portion 2 (right direction in FIG. 3), that is, the engagement pin 6a is removed from the notch 7 of the base end portion 4a. It shows a state where it is detached and retracted inside the free end 2a. Thereby, the restriction | limiting to the base end part 4a is cancelled | released, and the closing tool 4 can be rotated to the outward side of the storage area 3. FIG. In the configuration shown in the present embodiment, the rotation area of the base end portion 4a is provided up to the position where the closing tool 4 rotates in substantially the same direction as the extending direction of the free ends 2a, 2b. As described above, when the release ring 6 is pulled outward, the receiving area 3 is largely opened, so that the closing tool 4 does not hinder the detachment of the electric wire 30 from the receiving area 3 and can be easily performed. Can be removed.

  As described above, according to the configuration of the present embodiment, when the release ring 6 is pushed in and the rotation of the base end portion 4a is restricted, it is possible to easily store the electric wire 30 only by pushing it in from the outside. 3 and can be prevented from being detached in a good closed state. Further, by simply pulling the release ring 6, the accommodation area 3 can be largely opened and a state where the electric wire 30 can be easily detached can be formed.

  That is, since a rotating operation of a screw rod or the like is not required, it is possible to easily perform a work such as a remote operation in which a hand sense is difficult to be transmitted, and to greatly improve work efficiency.

  In addition, in this Embodiment, although the closing tool 4 in which only one joint 4d was formed was shown as an example, not only this but two or more may be provided. As the number of joints 4d increases, it can be flexibly avoided so as not to interfere with the object to be accommodated, so that the accommodation area 3 can be used more widely.

  Further, in the present embodiment, a configuration in which the urging acting from the base end 4a toward the retaining pin 4b is weaker than the urging acting from the free end 2a toward the base end 4a is an example. However, the present invention is not limited to this, and any of them may be set to be stronger. If there is at least one joint 4d, it is possible to pull out the closing tool 4 while avoiding the contained object.

  Furthermore, if it is the structure which has the joint 4d, it does not need to have a biasing means in the rotation location of the base end part 4a or the retaining pin 4b. In this case, the electric wire 30 is accommodated and held by using a mechanism that locks at a position (such as a closed position) where it is desired to be stably stopped, an engagement mechanism that engages the flange portion 2 and the closing tool 4, or the like. It is possible.

  Further, in the present embodiment, the configuration in which the coiled spring members 8 and 10 are employed as the biasing means is shown as an example, but any biasing means that can bias outwardly is used. Not exclusively. For example, a leaf spring may be used, or an urging unit using a repulsive force of an elastic member such as rubber may be used.

  In the present embodiment, the means for restricting the outward rotation of the base end 4a is the engagement pin 6a at the tip of the release ring 6 and the notch 7 formed on the periphery of the base end 4a. Although the example comprised by the combination was shown, you may be a structure which controls to a predetermined rotation area | region by making a penetration pin penetrate the curved long hole. Furthermore, the direction in which the engagement pin engages with the notch is not limited to the direction shown in FIGS. 2 and 3 and may be a direction orthogonal to the rotation surface of the base end.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is a perspective view showing the wire container 21 according to the present embodiment. In this electric wire container 21, the structure of the part by which the closing tool 24 is pivotally supported among the free ends 22a differs from 1st Embodiment.

  The flange portion 22 of the present embodiment is formed in a substantially U shape similarly to the first embodiment. However, a rotation node 27 is provided at the free end 22a on the side where the closing tool 24 is pivotally supported so as to be able to rotate around the axis C in the extending direction of the free end. As a result, the closing tool 24 can swing with the swinging portion 26 that is a part of the upper side of the free end 22a. FIG. 4A shows a state in which the electric wire receiving area 23 is closed, and FIG. 4B shows a state in which the receiving area 23 is opened by the above-described swinging motion.

  By being configured in this way, as in the first embodiment, in the state of (a), by pressing an electric wire (not shown) against the closing tool 24 from the outside, the base end portion 24 a or the retaining pin 24 b can be retracted to the inner side of the accommodation area 23. And after an electric wire is accommodated in the accommodating area | region 23, the spring member 28 (base end urging means) provided between the free end 22a and the base end part 24a, and the spring member 29 provided in the joint With the joint urging means, the closing tool 24 returns to the position where the accommodating area 23 is closed, and becomes a stable state (accommodating state).

  Further, in this accommodated state, since the electric wire is loosely fitted in the accommodating area 23, the electric wire container 21 is provided in the longitudinal direction of the electric wire even when a longitudinal tension or the like occurs in the electric wire. It is possible to stabilize the posture without being affected by the movement of the head.

(Third embodiment)
Subsequently, a third embodiment of the present invention will be described with reference to FIG. FIG. 5 shows a use state of the widening tool 50 provided at both ends with the wire container 1 shown in the first embodiment.

  The widening tool 50 is a tool that widens the distance between the electric wires 30 positioned on the upper side and the lower side of the three electric wires 30 arranged substantially in parallel in the same plane. An electric wire gripping portion 54 that grips the central electric wire 30 out of the three is provided substantially at the center of the widening tool 50. The central electric wire 30 is gripped by operating the remote control rod 40 connected to the electric wire gripping connecting portion 56. Here, a screw fastening type gripping structure is employed.

  Further, an expansion / contraction connection part 58 is provided next to the electric wire gripping connection part 56. After the widening tool 50 is fixed by grasping the central electric wire 30, the remote control rod 40 is removed from the electric wire grasping connecting portion 56 and replaced with the telescopic connecting portion 58. The widening tool 50 in the present embodiment can expand and contract the telescopic rod 52 by rotating the remote control rod 40 through the telescopic connecting portion 58.

  The telescopic rod 52 is composed of a main shaft 52a and an telescopic shaft 52b extending from both ends of the main shaft 52a, and the portion of the telescopic shaft 52b expands and contracts with respect to the main shaft 52a by the rotation operation of the telescopic connecting portion 58 by the remote control rod 40. It is the composition to do.

  As can be seen from FIG. 5, the closing tool 4 that closes the housing area 3 of the electric wire 30 of the collar 2 is disposed on the extending direction side of the telescopic bar 52. As a result, simply by extending the telescopic rod 52, the closure 4 of the flange 2 is pressed against the upper and lower electric wires 30, respectively, and by further expanding, the electric wire 30 is placed in the accommodation area 3 (in the flange 2). Can be accommodated. As described above, in the widening tool 50 in the present embodiment, it is possible to accommodate the upper and lower electric wires 30 and widen the distance between the electric wires 30 simply by gripping the central electric wire 30 and extending the telescopic rod 52. It becomes.

  Thus, in the widening tool 50 in this Embodiment, since the closure tool 4 of the electric wire container 1 provided in both ends is each arrange | positioned toward the expansion | extension direction of the expansion-contraction bar | burr 52, the electric wire 30 in the center. , The widening tool 50 is formed with the wire 30 receiving side of the wire gripping portion 54 facing downward so that the work can be performed on the front side even on the back side of the wire 30. The working efficiency is improved with respect to the rear side arrangement.

  Here, as can be seen from FIG. 5, the upper and lower electric wires 30 are loosely fitted in the housing area 3 of the flange 2. For this reason, even if the upper and lower electric wires 30 are pulled in the axial direction (longitudinal direction of the electric wires 30) by a cutting operation or the like, and the tension is changed, the widening tool 50 is connected to the electric wires 30 in the axial direction. The movement is not hindered, and the width of the widening tool 50 itself is not changed. That is, the widening tool 50 can stably hold the same angle as the initial setting state regardless of the working state, so that the distance between the upper and lower electric wires 30 can be always kept constant. It is possible to maintain good safety.

When the work is completed, first, the release rings 6 provided on the flanges 2 at both ends of the widening tool 50 are pulled using the remote control rod 40. Then, as described in the first embodiment, the restriction of the outward rotation of the closing tool 4 is released, and the space between the free ends 2a and 2b is opened.

  Next, the telescopic connecting portion 58 is remotely operated in this state, and the telescopic rod 52 is contracted, so that the distance between the upper and lower electric wires 30 returns to the original state. It becomes a withdrawal state.

  Finally, the widening tool 50 can be collected by loosening the central electric wire gripping portion 54.

  In the present embodiment, a configuration in which a gap is generated between the inside of the collar 2 and the tip of the closing tool 4 is shown as an example, but the tip of the closing tool 4 is engaged with the inside of the collar 2. You may be the structure to do. If comprised in this way, it will become possible to prevent the detachment | leave to the outward of the target object accommodated in the storage area 3 more effectively.

  On the contrary, as in the present embodiment, for the usage mode in which the accommodated electric wire 30 is in sliding contact with the inner wall of the flange 2 and the electric wire in the accommodated state does not act on the closing tool. As long as the opening side is closed at least so as not to allow the passage of the object, the space in the accommodation area 3 can be widely utilized and the weight of the member can be reduced by the amount that the closing tool 4 can be set short. Is possible.

  Moreover, in this Embodiment, although the structure which used the electric wire container 1 of FIG. 1 shown in 1st Embodiment for the both ends of the widening tool 50 was shown as an example, it shows in 2nd Embodiment. The wire container 21 of FIG. 4 may be used.

  Furthermore, in this Embodiment, although the storage area 3 of the electric wire container 1 showed the example which has arrange | positioned the opening side toward both sides of the expansion-contraction direction of the expansion-contraction bar | burr 52, with respect to the extending direction of the expansion-contraction bar | burr 52 You may be comprised so that it may open in the orthogonal direction. In particular, when it is configured to open in the same direction as the side of the remote control rod 40 facing the front end, it is possible to perform the accommodating operation of the electric wire 30 by pushing the widening tool 50 against the electric wire 30. , Make the work easier.

  The electric wire container of the present invention is provided with a joint on the closing tool, and can widely utilize the housing area formed by the collar portion, so that it can be reduced in size and weight. For this reason, in addition to being widely applicable to remote control tools, it is also useful for mountain climbing tools for which compact equipment is desired.
