Description

Technical Field

[0001] The present invention relates to an electric wire holder for a live wire distribution tool used in live wire distribution work in the energized erection and maintenance of electric wires, and a live wire distribution method.

Background Art

[0002] In the work of cutting electric wires in live work, a live wire distribution tool is used so that the ends of the cut electric wires do not touch each other. Many live wire distribution tools include a wire gripper for gripping the electric wire, a wire tensioner for pulling the gripped electric wire, and an electric wire holder for holding the electric wire that has been pulled and bent or cut and become unstable.

[0003] FIG. 9 is a diagram showing a conventional live wire distribution tool 100. The live wire distribution tool 100 is arranged so that the portion where the electric wire 200 needs to be cut is included between two wire grippers 102. Then, by contracting the wire tensioner 101 to which the two wire grippers 102 are connected, a bend is formed in the electric wire 200. The electric wire 200 is cut in the bent state and is placed in a separated state by two electric wire holders 103 so that the cut ends do not touch each other.

[0004] By using the live wire distribution tool 100 in this way, it is possible to prevent an energization accident and perform work safely in live work.

[0005] Such a live wire distribution tool is described in Patent Document 1.

Summary of the Invention

Problems to be Solved by the Invention

[0007] When using the live wire distribution tool 100 as shown in Fig. 9, if the end of the severed electric wire 200 sways in the wind or is held in an unstable state, there is a risk of contact with peripheral devices or operators. Therefore, it is desirable to hold the electric wire 200 at a position as close as possible to the cutting end.

[0008] Also, in the configuration of the wire holder 103, if the space for accommodating the electric wire 200 is too wide with respect to the diameter of the electric wire 200, the degree of freedom of the held electric wire 200 becomes too large. Therefore, it is desirable to hold it with a holding frame formed in a necessary minimum space as close as possible to the diameter of the electric wire 200.

[0009] On the other hand, when connecting the severed electric wires 200, a sleeve cover is often used to repair the cutting portion. And the covering of the severed electric wire 200 is peeled off from the end by a certain length. Therefore, the sleeve cover needs to have a length that can cover at least the area where the covering is peeled off.

[0010] By the way, since the connection of the electric wire 200 must be completed before covering it with the sleeve cover, a process of passing one of the electric wires 200 through the sleeve cover in advance before connection and sliding the sleeve cover over the connection portion after connection is required.

[0011] Here, in order to smoothly proceed with such a process, it is necessary to pay attention so that the sleeve cover and the wire holder 103 do not interfere with each other. However, if the wire accommodation space of the wire holder 103 is set to a size close to the diameter of the electric wire 200 as described above, the sleeve cover will interfere. Also, in order to avoid this, if the wire holder 103 is arranged at a position where it does not interfere with the sleeve cover, the two wire holders 103 are too far apart, so the cutting end of the electric wire 200 droops greatly and is unstable.

[0012] Therefore, an object of the present invention is to provide a wire holder for a live wire distribution tool that prevents interference with a sleeve cover and ensures a safe separation distance between the severed electric wires.

Means for Solving the Problem

[0013] In order to achieve the above object, an electric wire holder for a live wire distributing tool of the present invention is an electric wire holder of a live wire distributing tool that is rotatably attached to a wire tensioner having wire grippers arranged at both ends, and includes a holding frame that accommodates and holds an electric wire through an opening formed in a part thereof, a partition wall portion that separates regions while leaving a communication port in a part thereof so as to form at least two compartments having different sizes within the holding frame, and a clamping and fixing portion that clamps and fixes the wire tensioner.

[0016] Further, the electric wire holder for a live wire distributing tool of the present invention is characterized in that, in addition to the above configuration, it is clamped and fixed together with the wire tensioner by the clamping and fixing portion, and includes a gripping portion for performing a turning operation of the holding frame.

[0017] Further, the electric wire holder for a live wire distributing tool of the present invention is characterized in that, in addition to the above configuration, the gripping portion includes a contact plate portion provided along the wire tensioner, and a handle provided on the side opposite to the wire tensioner via the contact plate portion for performing a distribution operation.

[0018] Further, a live wire distributing method of the present invention is a live wire distributing method using a wire tensioner, two wire grippers arranged at both ends of the wire tensioner, and an electric wire holder having a first compartment through which a sleeve cover can pass and a second compartment for holding only an electric wire, attached to the wire tensioner, and includes a step of cutting the gripped electric wire between the two wire grippers, a step of pushing the sleeve cover attached to one end of the cut electric wire into the first compartment until it passes through the end portion, a step of moving the electric wire on the side where the sleeve cover is attached to the second compartment, and a step of distributing the end portions of the cut electric wires.

[0019] In addition to the above steps, the energized wire distribution method of the present invention further includes a step of moving, from the distributed position back to the original position, the wire on the side where the sleeve cover is attached among the wires, from the second section to the first section; a step of passing the sleeve cover through the first section and returning it to the end side; and a step of connecting the cut wires to each other and covering the connection portion with the returned sleeve cover.

Advantages of the Invention

[0020] As described above, according to the wire holder for an energized wire distribution tool of the present invention, inside the holding frame that houses and holds the wire, there are at least two compartments of different sizes separated with a communication port left partially. Thus, the wire accommodated from the opening can freely change its position within the holding frame by passing through the communication port. Therefore, for wires with relatively high hardness and difficult to distribute, the distribution can be performed while being arranged in the compartment closer to the clamping and fixing portion. Also, for wires that are easy to distribute or wires that need to be distributed largely due to high voltage, the distribution can be performed while being housed in the compartment located farther from the clamping and fixing portion. In this way, it becomes possible to freely select the distribution interval according to the target wire.

[0023] In addition, according to the wire holder for an energized wire distribution tool of the present invention, in addition to the above effects, the gripping portion for performing the turning operation of the holding frame is clamped and fixed together with the wire tensioner by the clamping and fixing portion. Therefore, the fixing of the holding frame to the wire tensioner and the fixing of the gripping portion to the holding frame can be achieved by a single fixing portion (clamping mechanism). As a result, the structure becomes simple, and it is possible to suppress an increase in weight along with the number of parts.

[0024] Further, according to the wire holder for energized wire distributing tool of the present invention, in addition to the above effects, since the contact plate portion is provided on the gripping portion along the wire tensioner, even when the gripping portion is inclined within the clamping and fixing portion during the turning operation, the contact plate portion abuts against the wire tensioner, preventing the posture from collapsing more than necessary. Thus, even when the fixing of the holding frame to the wire tensioner and the fixing of the gripping portion to the holding frame are performed by the same fixing portion (clamping mechanism), and even when looseness occurs in the fixing on the gripping portion side due to the difference in clamping pressure, the clamping state can be stably maintained.

[0025] Further, according to the energized wire distributing method of the present invention, since the wire is held using a wire holder having first and second compartments with different sizes inside, when handling a sleeve cover having a larger diameter with respect to the wire, the wire can be placed in the first compartment on the larger side, and when the wire after the sleeve cover has passed is widely distributed, the wire can be placed in the second compartment on the smaller side, enabling such proper use. Thereby, the wire to be distributed is not accommodated in an unnecessarily large space, so that the distributed state is stabilized.

[0026] Further, according to the energized wire distributing method of the present invention, in addition to the above effects, when returning from the distributed state to the original state and returning the sleeve cover to the portion where the wire is connected, the two first and second compartments with different sizes can be freely used properly to prevent interference between the wire holder and the sleeve cover. Thereby, the working efficiency and safety are improved.

Embodiments for Carrying out the Invention

[0028] Hereinafter, the wire holder for a live wire distribution tool and the live wire distribution method according to the embodiments of the present invention will be described with reference to the drawings.

[0029] <Wire Holder> FIG. 1 is an overall perspective view of a wire holder 1 for a live wire distribution tool according to an embodiment of the present invention. The wire holder 1 includes a holding frame 2 having an opening 2a formed therein, a clamping and fixing portion 8 for fixing the holding frame 2 to a tensioner, and a gripping portion 10 for performing a turning operation of the holding frame 2.

[0030] In the holding frame 2, the inner wire accommodation region is divided into two compartments 2b and 2c. These two compartments 2b and 2c are different in size, and the compartment 2b (the first compartment) closer to the clamping and fixing portion 8 is larger, and the compartment 2c (the second compartment) on the far side is relatively small. In the configuration according to the present embodiment, these two compartments 2b and 2c are arranged in a direction away from the clamping and fixing portion 8 for fixing the holding frame 2 to the tensioner.

[0031] The two compartments 2b and 2c are separated by a partition wall portion 4. The partition wall portion 4 extends from the inside of the holding frame 2, and the tip side is bent upward (toward the small compartment 2c side). This partition wall portion 4 is provided so as not to completely separate the two compartments 2b and 2c, but to leave a communication port 6 in part. This communication port 6 allows a wire without a sleeve cover to pass through. The compartment 2c forms a space that can stably hold the wire by suppressing the degree of freedom of the wire to a certain extent.

[0032] Of the two compartments 2b and 2c, an opening 2a is formed in the larger compartment 2b. The compartment 2b is formed to be large enough to accommodate an electric wire with a sleeve cover mounted thereon, as will be described later.

[0033] The opening / closing device 12 for opening and closing the opening 2a is formed with a long hole 12a penetrating in the longitudinal direction, and a guide pin 14 passes through the long hole 12a and is screwed to the outer surface of the holding frame 2. In this way, the opening / closing device 12 slides with the groove formed on the outer surface of the holding frame 2, the guide pin 14, and the guide plate 16 as sliding guides to open and close the opening 2a. A closing bolt 18 for fixing the closed state is provided at a portion of the opening 2a of the holding frame 2 where the lower end of the opening / closing device 12 fits. Here, the opening / closing device 12 in the closed state is represented by a solid line, and the opening / closing device 12 in the open state is represented by a dotted line.

[0034] Note that FIG. 1 shows, as an example, a configuration including a guide plate 16 formed with a through hole through which the opening / closing device 12 can slide. However, in order to stabilize a state where the position is not determined due to the swinging of the lower side of the opening / closing device 12 with the guide pin 14 as a fulcrum, it may be surrounded by a frame-shaped member instead of the guide plate 16.

[0035] FIG. 2 is an exploded view of the periphery of the gripping portion 10 of the electric wire holder 1 in FIG. 1. The gripping portion 10 is attached to a clamping and fixing portion 8 provided below the holding frame 2. Specifically, it is arranged together with a wire tensioner between the clamping frames 8c constituting the clamping and fixing portion 8, and is clamped and fixed by passing through an eyebolt 8a and an eye nut 8b. A slight clearance is provided between the clamping frame 8c and the side surface of the contact plate portion 10a of the gripping portion 10, and the fixing strength is adjusted by the force of tightening the eyebolt 8a and the eye nut 8b. With such a configuration, although the clamping and fixing portion 8 has only a single fastening structure, it prevents the clamping and fixing on the gripping portion 10 side from interfering with the fixing on the wire tensioner side, and the wire tensioner side can be stably clamped.

[0036] Figure 3 is a front view of the wire holder 1 in Fig. 1. As described above, the two compartments 2b and 2c inside the holding frame 2 have a size relationship, and it can be seen that the larger compartment 2b is provided on the nearer side and the smaller compartment 2c is provided on the farther side in the direction away from the clamping and fixing portion 8 fixed to the wire tensioner. In Fig. 3, for the purpose of size comparison, the wire 200 and the sleeve cover 201 are represented by dotted lines.

[0037] The smaller compartment 2c is formed as a space with a slightly larger diameter than the wire 200. Thereby, when the holding frame 2 is pivoted during live wire distribution, the wire 200 can be stably held and the separated state is also stable. Also, the communication port 6 is formed as a space with a slightly larger diameter than the wire 200, similar to the smaller compartment 2c.

[0038] On the other hand, the larger compartment 2b is formed to have a size capable of accommodating the sleeve cover 201. With such a configuration, when the sleeve cover 201 is attached to the wire 200 as will be described later, if the wire 200 is arranged on the larger compartment 2b side, the sleeve cover 201 can pass smoothly without interfering with the holding frame 2 of the wire holder 1.

[0039] Figure 4 is a perspective view of the gripping portion 10. It has been described with reference to Fig. 2 that the gripping portion 10 can be slightly inclined about the axis of the eyebolt 8a of the clamping and fixing portion 8 (see Fig. 2). On the other hand, as shown in Fig. 4, a contact plate portion 10a is provided on the gripping portion 10 so as to extend along the wire tensioner. By providing this contact plate portion 10a, even when the gripping portion 10 is inclined about the eyebolt 8a, it is possible to prevent the gripping portion 10 such as the handle 10b from interfering with the wire tensioner.

[0040] That is, according to the configuration such as the clamping and fixing part 8 (see FIG. 2) according to the present embodiment, the pressure by clamping is dispersed to the tensioner side and the gripping part 10 side. Here, in order to stabilize the turning operation of the wire holder 1 during sorting and the holding state of the wire 200 after sorting, it is necessary to stabilize the holding frame 2 with respect to the tensioner. Therefore, in the clamping and fixing part 8, it is necessary to preferentially consider the clamping and fixing on the tensioner side. However, if there is a slack in the clamping and fixing on the gripping part 10 side and the handle 10b or the like interferes with the tensioner, the turning operation will not be stable. For this reason, in the configuration according to the present embodiment, a contact plate part 10a is provided between the handle 10b of the gripping part 10 and the tensioner.

[0041] By the way, if the configuration is such that the tensioner side is preferentially clamped, when there is a slack in the fastening by the eye bolt 8a and the eye nut 8b, the degree of the slack appears as the movement on the gripping part 10 side first. Therefore, even at a remote position, an effect of grasping the slack state on the tensioner side can be obtained from the state such as the inclination of the handle 10b during the turning operation. Thereby, an accident in which the wire 200 in the sorted state drops can be prevented. In order to cause such an action, it is desirable to set the extending direction of the handle 10b to a direction intersecting the axial direction of the eye bolt 8a.

[0042] FIG. 5 is a perspective view showing the configuration of the live wire sorting tool 50 in the use state. The state in which the wire holder 1 according to the present embodiment is used in the live wire sorting tool 50 is shown. The wire holding part 1 is clamped and fixed to the telescopic rod of the tensioner 101 by the clamping and fixing part 8 (see FIG. 1). The clamping force is adjusted to a magnitude such that the holding frame 2 can be turned by a remote operation tool such as a gripper. In FIG. 5, the position when one of the two wire holders 1 is turned 180 degrees downward is represented by a dotted line.

[0043] <Live wire sorting method> FIG. 6 is a diagram for explaining the live wire distribution operation in the cutting work. Here, for the sake of convenience of explanation, the wire 200 and the sleeve cover 201 to be worked on are schematically represented by dotted lines. In the scene where the positional relationship between the wire 200 and the sleeve cover 201 in the wire holder 1 is mentioned, FIG. 3 shall be referred to as appropriate.

[0044] In FIG. 6(a), it shows the process in which the live wire distribution tool 50 is arranged so that the planned cutting location of the wire 200 to be worked on is included between the two wire holders 1. The wire 200 is accommodated through the opening 2a of the holding frame 2 and is held in the section 2b close to the clamping and fixing part 8 (see FIG. 3).

[0045] FIG. 6(b) shows the process of contracting the wire tensioner 101 from the state of FIG. 6(a) to form a bend (dip) in the wire 200. As a result, the tension at the planned cutting location disappears, and the work becomes an unloaded state where it is easy. At this stage, the coating of the wire 200 is peeled off.

[0046] FIG. 6(c) shows the process when the wire 200 is cut from the state of FIG. 6(b). The X mark in the figure represents the location where the wire 200 is cut.

[0047] FIG. 6(d) shows the process of attaching the sleeve cover 201 to one of the cut wires 200. Since the wire 200 is accommodated in the larger section 2b (the first section) of the two sections 2b and 2c in the holding frame 2 as described in FIG. 6(a), the sleeve cover 201 can pass through the holding frame 2 without interference.

[0048] FIG. 6(e) shows the process of moving the wire 200 to the section 2c (the second section) on the side far from the wire tensioner 101 among the two sections 2b and 2c of the holding frame 2. In FIG. 6(d), since the sleeve cover 201 has passed through the holding frame 2, the wire 200 can be accommodated in the smaller section 2c through the communication port 6.

[0049] Fig. 6(f) shows the process of distributing the electric wire 200 by rotating one of the two wire holders 1 by 180 degrees. In Fig. 6(e), since the electric wire 200 has been moved to the section 2c far from the tensioner 101, it is possible to greatly separate the electric wires 200 from each other. At this time, for safety, the ends of the cut electric wires 200 are covered with caps or the like.

[0050] As described above, according to the configuration of the present embodiment, when passing through the sleeve cover 201, the larger section 2b is used to prevent interference, and when distributing the electric wire 200, the smaller section 2c far from the tensioner 101 is used to create a large separation. Also, since this section 2c is formed in a space that slightly enlarges the diameter of the electric wire 200, the accommodated electric wire 200 is stably held without flailing during the turning operation for live wire distribution or during work in the distributed state.

[0051] Fig. 7 is a diagram for explaining the live wire distribution work in the connection construction. Here too, as in the case of Fig. 6, for convenience of explanation, the electric wire 200 and the sleeve cover 201 to be worked on are schematically shown by dotted lines. Also, it is the same to refer to Fig. 3 as appropriate.

[0052] Fig. 7(a) shows the state where the cut electric wire 200 has been distributed. At this time, the sleeve cover 201 is attached to one of the electric wires 200.

[0053] Fig. 7(b) shows the process of returning the distributed electric wire 200 to its original position. As described above, in the distributed state, since the electric wire 200 is accommodated in the smaller section 2c (second section), it can be safely returned to its original position without flailing during turning.

[0054] FIG. 7(c) shows the step of moving the electric wire 200 accommodated in the partition 2c of the holding frame 2 to the partition 2b (first partition) on the larger side. By this step, it becomes possible to prevent interference between the sleeve cover 201 that is moved to the cutting position to be repaired later and the holding frame 2 of the electric wire holder 1.

[0055] FIG. 7(d) shows the step of returning the sleeve cover 201 to the position where it covers the cutting portion after passing through the partition 2b on the larger side. Before the sleeve cover 201 is thus returned, the caps attached to the ends of the electric wire 200 for protection are removed and connected to each other.

[0056] As described above, also in the step of connecting the cut portion, since the partition in the holding frame 2 through which the sleeve cover 201 passes can be changed to the side where interference does not occur, the working efficiency is improved. Regarding the movement between the partitions 2b and 2c in these holding frames 2, the work can be performed without taking the electric wire 200 out of the holding frame 2. Therefore, similar to the cutting work in FIG. 6, safety is improved by preventing accidents such as the dropped electric wire 200.

[0057] <Modification Example> FIG. 8 is a diagram showing a modification example of the electric wire holder 1 in FIG. 1. Here, the same components as those of the electric wire holder 1 in FIG. 1 will be denoted by the same reference numerals.

[0058] FIG. 8(a) shows the electric wire holder 31 of the modification example. In the holding frame 32 of the electric wire holder 31, the partition wall portion 34 extends from the opening 2a side. The size and shape of the partition wall portion 34 are substantially the same as those of the partition wall portion 4 of the electric wire holder 1 in FIG. 1, although the directions are different. The width of the communication port 36 is about the same as that of the communication port 6 of the electric wire holder 1.

[0059] FIG. 8(b) shows the electric wire holder 41 of the modification example. In the holding frame 42 of the electric wire holder 41, the partition wall portion 44 extends from a position away from the opening 2a side, which is the same as that of the electric wire holder 1 in FIG. 1, but it is different in that the tip is not bent like the partition wall portion 4 of the electric wire holder 1. The width of the communication port 46 is about the same as that of the communication port 6 of the electric wire holder 1.

[0060] FIG. 8(c) shows the wire holder 51 of the modified example. In the holding frame 52 of the wire holder 51, partition walls 54 extend from both sides on the side of the opening 2a and the side away from the opening 2a. The tip of the partition wall 54 is linear in the same manner as the partition wall 44 of the wire holder 41 in FIG. 8(b). The width of the communication port 56 is about the same as that of the communication port 6 of the wire holder 1.

[0061] The configuration described above is an example of the present invention, and the following modified examples are also included.

[0062] (1) In the above embodiment, as an example, the inside of the holding frames 2, 32, 42, 52 of the wire holders 1, 31, 41, 51 is shown as being partitioned into two compartments 2b and 2c having different sizes. However, as long as it includes at least two compartments having a size relationship, three or more compartments may be formed.

[0063] (2) In the above embodiment, as an example, the inside of the holding frames 2, 32, 42, 52 of the wire holders 1, 31, 41, 51 is shown as having two compartments 2b and 2c of different sizes arranged in a row in a direction away from the wire tensioner 101 (or the clamping and fixing portion 8). However, as long as at least the larger compartment is formed on the side closer to the wire tensioner (or the clamping and fixing portion), the smaller compartment does not have to be arranged in a row in a direction away from the wire tensioner (or the clamping and fixing portion).

[0064] (3) In the above embodiment, as an example, the openings 2a formed in the holding frames 2, 32, 42, 52 are all shown as being formed on the side of the larger compartment 2b. However, the opening may be formed for the smaller compartment, or may be formed so as to open widely for both compartments. Further, when openings are formed for both compartments, they do not have to be a single opening, but may be formed separately for each.

[0065] (4) In the above-described embodiment, the handle 10b of the gripping portion 10 is shown as an example of a configuration formed to extend parallel to the telescopic rod of the wire tensioner 101. However, the handle for the turning operation does not have to be formed parallel to the telescopic direction of the wire tensioner 101. For example, it may be formed to extend in a direction orthogonal to the telescopic direction of the wire tensioner 101. Further, it is not limited to the configuration in which two handles are symmetrically formed like the handle 10b, and it may be on one side.

[0066] (5) In the above-described embodiment, the handle 10b of the gripping portion 10 is shown as an example of a configuration formed to have a length exceeding the contact plate portion 10a. However, as long as it is a configuration that can be stably held, the handle may have a shape shorter than the contact plate portion.
