In addition, in this specification, members having the same function are given the same or similar symbols. Additionally, repeated descriptions of members assigned the same or similar codes may be omitted.

(Definition of direction)

In this specification, the extension direction of the wire gripped by the wire gripper, or in other words, the extension direction of the wire accommodation space of the wire gripper, is defined as the “first direction.” In addition, when the wire gripper is provided with a lever member (lever member 40), the direction in which the wire material gripped by the wire gripper extends and the direction in which the lever member is pulled is defined as the “first direction”, and the first direction is defined as the first direction. The direction opposite to the direction is defined as the second direction. Additionally, in this specification, the first direction side of the wire gripper may be called “rear”, and the second direction side of the wire gripper may be called “front”.

(First Embodiment)

1 to 4, the wire gripper 1A in the first embodiment will be described. Fig. 1 is a schematic two-sided view schematically showing the wire gripper 1A in the first embodiment. On the right side of FIG. 1, a schematic front view is depicted, and on the left side of FIG. 1, a schematic side view is depicted. In addition, in the drawing (schematic side view) on the left side of FIG. 1, description of the lock member 50, etc. is omitted to avoid complicating the drawing. Fig. 2 is a schematic perspective view schematically showing an example of the guide portion GA. FIG. 3 is a schematic front view schematically showing an example of the lever member 40. Fig. 4 is a schematic front view schematically showing the wire gripper 1A in a modification of the first embodiment.

The wire gripper 1A in the first embodiment includes a first member 11, a second member 12, a swing member 20, and a first engaging portion 30.

The first member 11 has a first contact surface 11a that contacts the wire W (more specifically, the upper surface of the wire W). The cross-sectional shape of the first contact surface 11a perpendicular to the first direction DR1 is, for example, a curved shape inclined upward. The first member 11 may be comprised of one part or may be comprised of an assembly of multiple parts.

The second member 12 has a second contact surface 12a that contacts the wire W (more specifically, the lower side of the wire W). The cross-sectional shape of the second contact surface 12a perpendicular to the first direction DR1 is, for example, a downward curved shape. The second member 12 may be comprised of one part or may be comprised of an assembly of multiple parts.

When the first contact surface 11a and the second contact surface 12a contact the wire W, the first member 11 and the second member 12 grip the wire W. In addition, the wire W held by the first member 11 and the second member 12 is, for example, an electric wire (more specifically, a temporary electric wire).

The swing member 20 is connected to the first member 11 so as to be rotatable around the first axis AX1. More specifically, the wire gripper 1A is provided with a first pin member P1 that rotatably connects the swing member 20 and the first member 11, and the first pin member P1 is It is arranged along the first axis (AX1).

Additionally, the swing member 20 is connected to the second member 12 so as to be rotatable around the second axis AX2. More specifically, the wire gripper 1A is provided with a second pin member P2 that rotatably connects the swing member 20 and the second member 12, and the second pin member P2 is It is arranged along the second axis (AX2).

When the rocking member 20 rotates around the first axis AX1, the second member 12 connected to the rocking member 20 moves relative to the first member 11, thereby forming the first contact surface 11a. The distance between and the second contact surface 12a changes. Additionally, when the second contact surface 12a contacts the wire W, the second member 12 rotates about the second axis AX2 with respect to the swing member 20. In this way, the second contact surface 12a becomes parallel to the first contact surface 11a, and the gripping force is applied in a balanced manner to the wire W in contact with the first contact surface 11a and the second contact surface 12a. Additionally, the rocking member 20 may be comprised of one part or may be comprised of an assembly of multiple parts. In the example shown in FIG. 1, the rocking member 20 is a plate-shaped member. In addition, the rocking member 20 has a substantially triangular shape when viewed from the front, and each vertex of the triangle includes the above-described first axis AX1, the above-described second axis AX2, and the later-described second axis AX2. The third axis AX3 is arranged respectively. However, the shape and structure of the rocking member 20 are not limited to the example shown in FIG. 1.

The first coupling portion 30 is a portion that can be coupled to the distal end of a wire gripper lifting tool (in other words, a remote operation tool for lifting the wire gripper 1A upward). In the example shown in FIG. 1, the first engaging portion 30 is a through hole portion 30h.

In the example shown in FIG. 1, the first engaging portion 30 is disposed below the first contact surface 11a and the second contact surface 12a. More specifically, the posture of the first member 11 and the second member 12 is maintained such that the first contact surface 11a is located above the second contact surface 12a (in other words, the wire gripper 1A ) is lifted by the wire gripper lifting tool), the first engaging portion 30 is disposed below the first contact surface 11a and the second contact surface 12a.

When the first coupling portion 30 is disposed below the first contact surface 11a and the second contact surface 12a, the wire receiving space (SP) between the first contact surface 11a and the second contact surface 12a ) (in other words, the process of attaching the wire gripper 1A to the wire W) until the wire W is inserted into the wire W, the wire gripper lifting tool does not intersect the wire W. More specifically, in the process of mounting the wire gripper 1A to the wire W, the portion of the wire gripper lifting tool that engages the first engaging portion 30 is always located below the wire W. It is located. Therefore, the wire W and the wire gripper lifting tool do not interfere, and the work of attaching the wire gripper 1A to the wire W can be performed smoothly.

Next, optional additional configurations that can be employed in the wire gripper 1A of the first embodiment will be described.

(First member 11)

The first member 11 has an upper portion 111 located above the first contact surface 11a and the second contact surface 12a, and an upper portion 111 located below the first contact surface 11a and the second contact surface 12a. It may have a lower part 112 and an intermediate part 113 located at a height between the height of the first contact surface 11a and the height of the second contact surface 12a.

In the example shown in FIG. 1 , the first engaging portion 30 is disposed at the lower portion 112 of the first member 11 . For this reason, in the process of mounting the wire gripper 1A to the wire W, the work of mounting the wire gripper 1A to the wire W is performed without interference between the wire W and the wire gripper lifting tool. It can be done smoothly.

In addition, when the first engaging portion 30 is installed on the first member 11 (more specifically, the lower portion 112 of the first member 11), the wire gripper 1A is connected to the wire gripper 1A. In the process of mounting to (W), the positional relationship between the first engaging portion 30 and the first member 11 (more specifically, the first contact surface 11a) does not change. More specifically, when the first member 11 contacts the wire W, the first engaging portion 30 does not oscillate with respect to the first member 11. Therefore, the task of mounting the wire gripper 1A to the wire W can be performed smoothly. On the other hand, for example, when the first engaging portion 30 is disposed on the swinging member 20, the first member 11 contacts the wire W, so that the first engaging portion 30 is disposed on the swinging member 20. 20), it swings with respect to the first member 11. There is a possibility that the operation of attaching the wire gripper 1A to the wire W may be hindered by the shaking.

(Lever member (40))

The wire gripper 1A in the first embodiment may be provided with a lever member 40 rotatably connected to the swing member 20 about the third axis AX3. Additionally, the wire gripper 1A may be provided with a third pin member P3 that rotatably connects the swing member 20 and the lever member 40. The third pin member P3 is arranged along the third axis AX3.

As shown in FIG. 1 , when the lever member 40 is pulled in the first direction DR1, the swing member 20 connected to the lever member 40 swings around the first axis AX1. As the rocking member 20 swings, the second contact surface 12a of the second member 12 moves in a direction approaching the first contact surface 11a of the first member, and as a result, the wire (W ) is held by the first member 11 and the second member 12. In addition, in the example shown in FIG. 1, the second end 40b of the lever member 40 (an end opposite to the first end connected to the swing member 20) is a free end. The free end is connected to, for example, a stretchable rod member 70 described later. As shown in FIG. 1, two or more through holes 40h may be formed in the second end 40b of the lever member 40 along the vertical direction. In this case, it becomes possible to switch the position where the second end portion 40b is connected to the rod member 70 in the vertical direction.

(Guide section (GA))

The wire gripper 1A (more specifically, the first member 11) may have a guide portion GA that guides the movement of the lever member 40.

In the example shown in FIG. 1 , the guide portion GA is installed at the rear portion (portion on the first direction DR1 side) of the first member 11. In the example shown in FIG. 1, the guide portion GA extends so as to protrude downward and rearward from the rear end of the first contact surface 11a (or the rear end of the second contact surface 12a).

In the example shown in FIG. 2 , the guide portion GA is provided with a guide wall Gw that guides the lever member 40 . The guide wall Gw is, for example, a wall that defines a through hole Gh through which the middle portion 43 (see FIG. 1) of the lever member 40 is inserted. The guide portion GA regulates the position of the lever member 40, thereby suppressing excessive displacement of the lever member 40 in the lateral direction (direction perpendicular to the paper in FIG. 1), and as a result, the lever member 40 Excessive load is suppressed from being applied to the connection portion between (40) and the swing member (20).

In the example shown in FIG. 1 , the first engaging portion 30 is disposed on the guide portion GA that guides the movement of the lever member 40. More specifically, the first engaging portion 30 is the lower end portion of the guide portion (in other words, the lower portion 112b of the first member 11) located below the lever member 40 among the guide portion GA. It is placed in

When the first engaging portion 30 is disposed on the guide portion GA that guides the movement of the lever member 40, the first engaging portion 30 has the first contact surface 11a and the second contact surface. (12a), and is disposed at a position sufficiently far away from the rocking member 20. For this reason, the field of view of the operator performing the task of attaching the wire gripper 1A to the wire W is prevented from being obstructed by the wire gripper lifting tool coupled to the first engaging portion 30.

(Coupling portion 42 of lever member 40)

The lever member 40 may have an engaging portion 42 that can be engaged with the guide portion GA (more specifically, the lower end portion 112b). In the example shown in FIG. 3 , the engaging portion 42 is provided on the lower surface 40s of the lever member 40. Moreover, in the example shown in FIG. 3, the engaging part 42 is a concave part 40d formed in the lower surface 40s of the lever member 40.

When the lever member 40 is provided with a coupling portion 42 that can be coupled to the guide portion GA, it is possible to maintain the relative position between the lever member 40 and the guide portion GA.

When the wire gripper 1A is lifted by the wire gripper lifting tool, when the lever member 40 moves relative to the first member 11, the swing member 20 swings. As a result, the gap between the first contact surface 11a of the first member 11 and the second contact surface 12a of the second member 12 changes. When the gap between the first contact surface 11a and the second contact surface 12a changes, the wire W is inserted into the wire receiving space SP defined by the first contact surface 11a and the second contact surface 12a. There is a possibility that your work will be hindered.

In contrast, when the lever member 40 is provided with a coupling portion 42 that can be coupled to the guide portion GA, when the wire gripper 1A is lifted by the wire gripper lifting tool, the lever member 40 does not move relative to the first member 11. Accordingly, the gap between the first contact surface 11a and the second contact surface 12a is maintained at a constant interval, so that the wire is stored in the wire receiving space SP defined by the first contact surface 11a and the second contact surface 12a. The task of inserting (W) can be performed smoothly.

In addition, in the example shown in FIG. 1, the engagement between the engaging portion 42 and the guide portion GA (more specifically, the lower portion 112b) is maintained by gravity acting on the lever member 40. . In other words, by lifting the lever member 40 against the gravitational force acting on the lever member 40, it is possible to release the engagement between the engaging portion 42 and the guide portion GA.

(Arrangement of the first coupling portion 30)

In the example shown in FIG. 1, the first engaging portion 30 is disposed on the rear portion of the first member 11 (more specifically, the guide portion GA that guides the movement of the lever member 40). It is done. Generally, as shown in FIG. 4, the first engaging portion 30 is disposed at the front portion 11f (more specifically, the end portion on the second direction DR2 side) of the first member 11. It can be done. In addition, when the first engaging portion 30 is arranged to protrude downward and forward beyond the front end of the first contact surface 11a (or the front end of the second contact surface 12a), the wire gripper 1A The field of view of the operator performing the work of mounting the wire W is prevented from being obstructed by the wire gripper lifting tool coupled to the first engaging portion 30.

(Shape or structure of the first coupling portion 30)

In the example shown in FIG. 1 or FIG. 4 , the first engaging portion 30 is a through hole portion 30h. Additionally, the central axis AX of the through hole portion 30h is parallel to the first axis AX1. In general, the central axis AX of the through hole portion 30h may be parallel to the first direction DR1. In addition, when the first engaging portion 30 is a through hole portion 30h, the inner diameter of the hole portion is, for example, 13 mm or more and 45 mm or less.

In the example shown in FIG. 1 or FIG. 4 , the first engaging portion 30 is comprised of a first engaging member 3 that is separate from the first member 11. In general, the first engaging portion 30 may be formed integrally with the first member 11. In other words, the first engaging portion 30 may be formed by subjecting the first member 11 to hole forming processing or the like. Additionally, the first engaging member 3 may have a protruding portion 32 (for example, a shoulder portion). In the example shown in FIG. 1, the protrusion 32 is disposed above the central axis AX of the through hole 30h (more specifically, above the upper end of the through hole 30h). In a state where some kind of wire gripper lifting tool (e.g., SHOTGUN STICK (manufactured by HASTINGS), SHOTGUN STICK (manufactured by AB CHANCE)) is engaged with the first engaging portion 30, the wire gripper lifting tool When a portion contacts the protrusion 32, the first engaging member 3 (and the wire gripper 1A) is suppressed from rocking relative to the wire gripper lifting tool. Accordingly, when the protrusion 32 is formed on the first engaging member 3, the task of approaching the wire gripper 1A toward the wire W becomes easy. In the example shown in FIG. 1, the protruding portion 32 protrudes in a direction away from the vertical surface Pa passing through the central axis AX of the through hole 30h. Additionally, the protrusion 32 includes a first protrusion 32a and a second protrusion 32b, and the protrusion direction of the first protrusion 32a is opposite to the protrusion direction of the second protrusion 32b. .

In the example shown in FIG. 1 or FIG. 4 , a second through-hole portion 31h is formed in the first engaging member 3 in addition to the through-hole portion 30h functioning as the first engaging portion 30. there is. The second through-hole portion 31h is a hole portion that contributes to reducing the weight of the first coupling member 3. In addition, it is preferable that the hole shape of the second through-hole portion 31h is different from that of the through-hole portion 30h. Since the hole shape of the second through-hole portion 31h is different from that of the through-hole portion 30h, the operator can easily recognize which hole portion the wire gripper lifting tool should be engaged with. there is. In the example shown in FIG. 1 or FIG. 4 , the hole shape of the through-hole portion 30h is circular, and the hole shape of the second through-hole portion 31h is non-circular.

(Lock member (50))

The wire gripper 1A may be provided with a lock member 50. The lock member 50 is a member for maintaining the state in which the wire W is held between the first contact surface 11a and the second contact surface 12a, in other words, the first contact surface 11a and the second contact surface ( 12a) It is a member that defines the distance between.

In the example shown in FIG. 1, the first part 51 of the lock member 50 is mounted on the first member 11, and the second part (not shown) of the lock member 50 is a rocking member ( 20). In addition to the first part 51 mounted on the first member 11 and the second part mounted on the rocking member 20, the lock member 50 includes an operation portion 50a (e.g. , an operating ring, and a threaded rod 50b for adjusting the gap between the first part 51 of the lock member 50 and the second part of the lock member 50. Additionally, a screw for screwing onto the threaded rod 50b is formed on one side of the first part 51 or the second part of the lock member 50. In addition, on the other side of the first part 51 or the second part of the lock member 50, a screw for screwing onto the screw rod 50b is not formed, in other words, the screw rod 50b can be inserted through. A through hole is formed. Then, the screw rod 50b rotates by rotating the operating portion 50a (eg, operating wheel) using a remote operating tool. When the threaded rod 50b rotates, one of the first portion 51 or the second portion of the lock member 50 is screwed to the threaded rod 5b, so that the first portion of the lock member 50 The gap between 51 and the second part of the lock member 50 becomes smaller, and the rocking member 20 swings. As the swing member 20 swings, the distance between the first contact surface 11a and the second contact surface 12a decreases, and the wire W is gripped between the first contact surface 11a and the second contact surface 12a. do.

By manipulating the lock member 50 with the wire W disposed between the first contact surface 11a and the second contact surface 12a, the first contact surface 11a and the second contact surface 12a The gripping state of the wire (W) is maintained. Additionally, the lock member 50 restricts the rocking member 20 from rocking in the direction in which the distance between the first contact surface 11a and the second contact surface 12a increases. For this reason, the wire gripper 1A is prevented from unintentionally falling off from the wire W.

(Second Embodiment)

On the right side of Figure 5, a schematic front view is depicted, and on the left side of Figure 5, a schematic side view is depicted. In addition, in the drawing (schematic side view) on the left side of FIG. 5, description of the lock member 50, etc. is omitted to avoid complicating the drawing. Fig. 6 is a schematic side view schematically showing the wire gripper 1B in the second embodiment. FIG. 7 is a schematic front view schematically showing an example of the guide member 60. FIG. 8 is a schematic front view schematically showing another example of the guide member 60. FIG. 9 is a schematic front view schematically showing another example of the guide member 60. 10 to 12 are schematic two-sided views schematically showing the wire gripper 1B in the second embodiment.

In the second embodiment, description will be made focusing on points that are different from the first embodiment, and repeated explanation of matters already explained in the first embodiment will be omitted. Therefore, even if it is not explicitly explained in the second embodiment, it goes without saying that matters already explained in the first embodiment can be adopted in the second embodiment.

The wire gripper 1B in the second embodiment includes a first member 11, a second member 12, a swing member 20, and a guide member 60. The wire gripper 1B may be provided with a lever member 40.

Since the first member 11, the second member 12, the swing member 20, and the lever member 40 have been explained in the first embodiment, the first member 11, the second member 40 Repeated descriptions of the member 12, the swing member 20, and the lever member 40 are omitted.

The guide member 60 is a member that guides the wire W to the wire receiving space SP between the first contact surface 11a and the second contact surface 12a, and includes a closure portion 61 and a guide portion 62. ) is provided.

The closing portion 61 is a portion that closes at least part of the side of the wire accommodation space SP. The closing portion 61 prevents the wire W inserted into the wire receiving space SP from escaping from the wire receiving space SP.

The guide portion 62 is a portion that guides the wire W pressing the guide portion 62 toward the wire accommodation space SP.

When the wire gripper 1B is provided with the closing portion 61 and the guide portion 62, the wire rod W is placed in the wire receiving space SP between the first contact surface 11a and the second contact surface 12a. The work of inserting becomes easier, and the wire W is prevented from escaping from the wire receiving space SP. As a result, the task of mounting the wire gripper 1B to the wire W becomes easy.

Next, optional additional configurations that can be employed in the wire gripper 1B of the second embodiment will be described.

(Overall shape of guide member 60)

In this case, the operator can check whether the wire W is appropriately arranged inside the wire accommodation space SP through the gap G.

(Closed portion (61))

In the examples shown in FIGS. 10 and 11 , when the guide portion 62 of the guide member 60 is pressed by the wire W, the closing portion 61 moves in a direction away from the wire accommodation space SP. It is structured to do so. In addition, FIG. 10 shows a state before the guide portion 62 is pressed by the wire W, and FIG. 11 shows a state where the guide member 60 is pressed by the wire W.

With the above configuration, the wire W in contact with the guide portion 62 is smoothly guided into the wire accommodation space SP (see arrow A in FIG. 11).

In the example shown in FIG. 11 , the closing portion 61 is in a first position that allows the wire W to be inserted into the wire receiving space SP. When the closing portion 61 is in the first position, the width of the opening OP between the inside of the wire receiving space SP and the outside of the wire receiving space SP (more specifically, the width of the opening OP (more specifically, the width of the closing portion 61) The minimum distance between the lower end and the second member 12 is larger than the diameter of the wire W. Accordingly, the wire W can cross the opening OP and enter the wire receiving space SP.

On the other hand, in the example shown in FIG. 12, the closing portion 61 is in the second position to prevent the wire W from escaping from the wire accommodation space SP. When the closed portion 61 is in the second position, the width of the opening OP described above is smaller than the diameter of the wire W. Accordingly, the wire W is prevented from falling out from the inside of the wire accommodation space SP across the opening OP toward the outside.

In the examples shown in FIGS. 11 and 12, the position of the closing portion 61 is a first position (see FIG. 11) that allows the wire W to be inserted into the wire receiving space SP, and the wire W ) is position changeable between the second positions (see FIG. 12) that prevent the wire from deviating from the wire receiving space (SP). Therefore, not only is it easy to insert the wire W into the wire receiving space SP, but also the wire W inserted into the wire receiving space SP is prevented from escaping from the wire receiving space SP. .

From the viewpoint of effectively preventing the wire W inserted into the wire accommodation space SP from escaping from the wire accommodation space SP, the closing portion 61 moves from the first position (see FIG. 11) to the second position. It is preferable that it is elastically pressed in the direction toward (see Fig. 12).

In the examples shown in FIGS. 11 and 12 , the wire gripper 1B is provided with an elastic urging member 68, and the closing portion 61 is held in the first position by the elastic urging member 68 (FIG. 11 is elastically pressed in the direction from (see ) to the second position (see FIG. 12 ). More specifically, one end of the elastic pressing member 68 is supported by a guide member support member 69 mounted on the first member 11, and the other end of the elastic pressing member 68 is a guide member ( It is arranged to contact the proximal end of 60). And, the guide member 60 (more specifically, the proximal end of the guide member 60) disposed between the guide member support member 69 and the first member 11 is pressed by the elastic pressing member 68. , the closing portion 61 is elastically pressed in the direction from the first position toward the second position.

Additionally, from the viewpoint of enabling the position of the closing portion 61 to be smoothly changed between the first position and the second position, the guide member 60 is attached to the shaft portion 69a of the guide member support member 69. It is preferable that the posture can be changed between a posture perpendicular to the guide member support member 69 and a posture inclined with respect to the shaft portion 69a of the guide member support member 69 (excluding the vertical posture). Because the guide member 60 can change its posture with respect to the shaft portion 69a, the closure portion 61 can be inclined in a direction away from the wire accommodation space SP as it faces downward (see Fig. 11). Due to the inclination, the width of the opening OP is expanded. In addition, since the guide member 60 can change its posture with respect to the shaft portion 69a, the closed portion 61 can be parallel to the vertical direction (see Fig. 12). When the closure portion 61 becomes parallel to the vertical direction, the width of the opening OP is reduced.

In addition, in order to enable the guide member 60 to change its posture with respect to the shaft portion 69a, the inner diameter of the insertion hole 60h (see FIG. 7, etc.) formed in the guide member 60 is the insertion hole 60h. It is preferable that it is sufficiently larger than the outer diameter of the shaft portion 69a inserted into. In addition, it is preferable that the proximal end of the guide member 60 is loosely sandwiched between the head 69b of the guide member support member 69 and the first member 11. Since the gap between the head portion 69b of the guide member support member 69 and the first member 11 is larger than the thickness of the proximal end portion of the guide member 60, the proximal end portion of the guide member 60 is the shaft portion 69a. ) can be inclined for.

In the example shown in FIG. 11, the number of elastic pressing members 68 that elastically presses the closing portion 61 in the direction from the first position to the second position is two, and the number of elastic pressing members 68 is: There may be one or three or more.

In the example shown in FIG. 11, the guide member 60 and the elastic pressing member 68 that elastically presses the closing portion 61 are separate entities. In general, the guide member 60 itself may elastically press the closing portion 61 in a direction from the first position toward the second position. For example, when the guide member 60 is a leaf spring, the guide member 60 itself elastically presses the closing portion 61 in the direction from the first position toward the second position.

As shown in FIG. 13, a convex portion 610 may be formed on the surface of the closed portion 61 facing the wire accommodation space SP. When the convex portion 610 is formed in the closed portion 61, the wire W in contact with the convex portion 610 is guided in a direction toward the center of the wire accommodation space SP. In this case, the wire W is guided by the convex portion 610 in addition to the guide portion 62, so that the wire W is easily guided toward the center of the wire accommodation space SP.

(Guide part (62))

In the example shown in FIG. 6 , the guide portion 62 has a proximal end portion 62a connected to the closure portion 61 and a distal end portion 62b. The extension direction of the guide portion 62, in other words, the direction from the base end portion 62a toward the distal end portion 62b, is a direction away from the wire accommodation space SP.

In the example shown in FIG. 6 , the guide portion 62 is provided with a guide surface 62s that guides the wire W by contacting the wire W. Additionally, the guide surface 62s is an inclined surface inclined with respect to a surface perpendicular to the first axis AX1. More specifically, when the closing portion 61 is in the first position (see FIG. 6), the guide surface 62s is inclined upward in a direction approaching the wire accommodation space SP. For this reason, when the wire W comes into contact with the guide surface 62s, the wire W is guided toward the wire accommodation space SP. Additionally, the guide surface 62s may be a flat inclined surface or a curved inclined surface.

In the example shown in FIG. 5 , the wire gripper 1B includes, in addition to the guide member 60, the first engaging portion 30 described in the first embodiment. In general, the wire gripper 1B does not need to be provided with the first coupling portion 30.

In the example shown in FIG. 14 , the second wire gripper 2 includes a first member 11, a second member 12, a swing member 20, and a lever member 40. The second wire gripper 2 may be provided with a second engaging portion 80 and/or a guide member 60.

The first member 11, the second member 12, the swing member 20, the lever member 40, and the guide member 60 have been explained in the first or second embodiment. Therefore, repeated descriptions of these configurations are omitted.

The second coupling portion 80 is a portion that can be coupled to the front end of a wire gripper lifting tool (in other words, a remote operation tool for lifting the second wire gripper 2 upward). In the example shown in FIG. 14, the second engaging portion 80 is a through hole portion 80h. The second coupling portion 80 has the same configuration as the first coupling portion 30. Accordingly, repeated description of the second coupling portion 80 will be omitted. In addition, in the description of the first engaging portion 30 in the first embodiment, “first engaging member 3”, “first engaging portion 30”, and “through hole portion 30h” , “Second through hole portion 31h”, respectively, “Second engaging member 8”, “Second engaging portion 80”, “Through hole portion 80h”, and “Second through hole portion. If replaced with “(81h)”, the second coupling portion 80 is explained.

In the example shown in Fig. 14, the stretchable rod member 70 is connected to the wire gripper 1 (more specifically, the second end 40b of the lever member 40 of the wire gripper 1). . Additionally, the stretchable rod member 70 is connected to the second wire gripper 2 (more specifically, the second end 40b of the lever member 40 of the second wire gripper 2).

The stretchable rod member 70 is a member for changing the distance between the wire gripper 1 and the second wire gripper 2. In the example shown in FIG. 14, the first end 70a of the rod member 70 is connected to the wire gripper 1, and the second end 70b of the rod member 70 is connected to the second wire gripper 2. ) is connected to.

In a state where the wire gripper 1 grips the first part of the wire W and the second wire gripper 2 grips the second part of the wire W, the rod member 70 is held as a rod member. When contracted in the direction along the longitudinal axis L1, the distance between the wire gripper 1 and the second wire gripper 2 is reduced. As a result, the portion of the wire W located between the wire gripper 1 and the second wire gripper 2 is relaxed.

The rod member 70 includes an outer member 71, an inner member 72, and an operating portion 73. The operation unit 73 is a part for manipulating the relative movement of the inner member 72 with respect to the outer member 71. The operating unit 73 is connected to the rod member 70 and is rotatable around the fourth axis AX4. The manipulation unit 73 has a coupling portion 730 to which the distal end of the remote manipulation member is coupled.

An example of a mechanism for contracting the stretchable rod member 70 using a remote operation member will be described. As an example, (A) a first bevel gear that rotates around the fourth axis AX4 together with the operating portion is installed in the operating portion 73, and (B) a first bevel gear and a load transmission are installed in the outer member 71. A second bevel gear that can be connected is disposed, (C) the second bevel gear rotates around the longitudinal axis L1 of the rod member 70, together with a threaded rod with an outer screw disposed on the outer periphery, ( D) It is assumed that the inner member 72 is screwed to the threaded rod. In this case, when the control unit 73 is rotated around the fourth axis AX4 by the remote control member, the first bevel gear rotates around the fourth axis AX4, and the second bevel gear rotates around the rod member 70. ) rotates around the longitudinal axis (L1). When the second bevel gear rotates around the longitudinal axis (L1), the threaded rod rotates around the longitudinal axis (L1). When the threaded rod rotates around the longitudinal axis L1, the inner member 72 screwed to the threaded rod moves in a direction in which it is drawn into the outer member 71. In this way, the rod member 70 contracts.

Additionally, in the third embodiment, the mechanism for contracting the rod member 70 is not limited to the mechanism described above.

By contracting the rod member 70, the wire W (part of the wire W) located between the wire gripper 1 and the second wire gripper 2 is relaxed, and then the wire rod is cut, and The work of dividing the pre-existence is carried out. First, the loose portion of the wire W is cut by an arbitrary cutting tool. As a result, a first cut end and a second cut end are formed in the wire W. Next, the first cut end and the second cut end are cut (for example, cut in an upward and downward direction). The above process (more specifically, the rod member ( A process of shrinking 70), a process of cutting the relaxed portion of the wire W formed by contraction of the rod member 70 with a cutting tool, and dividing the first cut end and the second cut end formed by cutting. process), the cutting work of the wire rod is completed.

In the example shown in FIG. 15, the number of accommodation spaces CP of the first wire support 90a is two, but the number of accommodation spaces CP of the first wire support 90a is one or There may be three or more. The first wire support member 90a has a frame member 91 and an opening and closing member 92 that opens and closes the opening of the frame member 91. The opening and closing member 92 is connected to the operation unit 93, and by operating the operation unit 93, the opening and closing member 92 can be switched from the closed state to the open state. When the opening and closing member 92 is in the open state, the operator can insert the wire W into the accommodation space CP of the first wire support tool 90a using a remote operation tool. Additionally, when the opening and closing member 92 is in the open state, the operator can take out the wire W from the accommodation space CP of the first wire support tool 90a using a remote operation tool.

In dividing the first cut end and the second cut end of the wire, for example, with the wire connected to the first cut end arranged in the receiving space CP, the first wire support member 90a is used as a rod. Simply rotate the member 70 around its longitudinal axis (L1). In general, the cutting operation may be performed by moving the wire disposed in the first accommodation space CP1 to the second accommodation space CP2 using a remote operation tool.

In the example shown in FIG. 14 , the second wire support member 90b has a frame member 94 and an opening and closing member 95 that opens and closes the opening of the frame member 94. The frame member 94 has the same structure as the frame member 91 described above, and the opening and closing member 95 has the same structure as the opening and closing member 92 described above. Accordingly, repeated descriptions of the frame member 94 and the opening and closing member 95 are omitted.

The wire W in contact with the guide portion 62 of the guide member 60 is guided to the wire accommodation space SP by the guide portion 62. In this case, it is easy to insert the wire W into the wire receiving space SP. Additionally, the closing portion 61 of the guide member 60 prevents the wire W inserted into the wire receiving space SP from escaping from the wire receiving space SP. Therefore, the task of attaching the wire gripper 1 to the wire W can be performed more reliably.

Alternatively, or additionally, a guide member 60 may be mounted on the second wire gripper 2 of the wire cutting tool 100 in the third embodiment.

In the third embodiment, one of the wire gripper 1 and the second wire gripper 2 may be connected to the rod member 70 so as to be able to swing around the swing axis.

In this case, the wire cutting tool 100 can be lifted using the wire gripper lifting tool while the first coupling portion 30 is coupled to the wire gripper lifting tool. The first engaging portion 30 is disposed below the first contact surface 11a and the second contact surface 12a of the wire gripper 1. For this reason, the wire gripper 1 can be easily mounted on the wire W without the wire gripper lifting tool interfering with the wire W. After the wire gripper 1 is mounted on the wire W, the second wire gripper 2 is lifted using a remote operation tool. By the lifting operation, the rod member 70 is lifted upward while rotating around the swing axis with respect to the wire gripper 1. After that, the second wire gripper 2 is mounted on the wire W.
