Detailed Description

Hereinafter, the wire grip 1 and the wire cutting tool 100 according to the embodiment will be described in detail with reference to the drawings. In this specification, the same or similar reference numerals are given to components having the same kind of functions. Note that, in some cases, redundant description of components to which the same or similar reference numerals are attached will be omitted.

(definition of orientation)

In the present specification, the extending direction of the wire gripped by the wire grip, in other words, the extending direction of the wire housing space of the wire grip, is defined as a "first direction". When the wire tightener includes the operating lever member (operating lever member 40), the direction in which the wire gripped by the wire tightener extends and the direction in which the operating lever member is pulled is defined as a "first direction", and the direction opposite to the first direction is defined as a second direction. In this specification, the first direction side of the wire grip may be referred to as "rear", and the second direction side of the wire grip may be referred to as "front".

(first embodiment)

The turnbuckle 1A in the first embodiment is explained with reference to fig. 1 to 4. Fig. 1 is a schematic two-dimensional view schematically showing a wire grip 1A in the first embodiment. A schematic front view is shown on the right side of fig. 1, and a schematic side view is shown on the left side of fig. 1. In the left-hand side view (simplified side view) of fig. 1, the lock member 50 and the like are not described to avoid complication of the drawing. Fig. 2 is a schematic perspective view schematically showing an example of the guide part 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 grip 1A in a modification of the first embodiment.

The wire grip 1A according to the first embodiment includes a first member 11, a second member 12, a swinging 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 side 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 that is concave toward the upper side. Although the first member 11 may be constituted by 1 part, it may be constituted by a combination of a plurality of parts.

The second member 12 has a second contact surface 12a that contacts the wire W (more specifically, the lower side surface of the wire W). The cross-sectional shape of the second contact surface 12a perpendicular to the first direction DR1 is, for example, a curved shape that is concave toward the lower side. Although the second member 12 may be constituted by 1 part, it may be constituted by a combination of a plurality of parts.

The first contact surface 11a and the second contact surface 12a contact the wire W, and the first member 11 and the second member 12 can grip the wire W. The wire rod W gripped by the first member 11 and the second member 12 is, for example, an electric wire (more specifically, a bridged electric wire).

The swing member 20 is connected to the first member 11 to be rotatable about a first axis AX 1. More specifically, the wire grip 1A includes a first pin member P1, the first pin member P1 rotatably connects the swing member 20 and the first member 11, and the first pin member P1 is disposed along the first axis AX 1.

The swing member 20 is connected to the second member 12 so as to be rotatable about the second axis AX 2. More specifically, the wire grip 1A includes a second pin member P2, the swing member 20 and the second member 12 being rotatably coupled to each other by the second pin member P2, and the second pin member P2 is disposed along the second axis AX 2.

When the swing member 20 is rotated about the first axis AX1, the second member 12 connected to the swing member 20 moves relative to the first member 11, so that the distance between the first contact surface 11a and the second contact surface 12a changes. When the second contact surface 12a contacts the wire W, the second member 12 rotates about the second axis AX2 relative to the swinging member 20. In this way, the second contact surface 12a is parallel to the first contact surface 11a, and the gripping force is uniformly applied to the wire W with which the first contact surface 11a and the second contact surface 12a are in contact. Although the swing member 20 may be constituted by 1 component, it may be constituted by a combination of a plurality of components. In the example shown in fig. 1, the swing member 20 is a plate-like member. The swing member 20 has a substantially triangular shape in a front view, and the first axis AX1, the second axis AX2, and a third axis AX3, which will be described later, are arranged at each vertex of the triangle. However, the shape and structure of the swing member 20 are not limited to the example shown in fig. 1.

The first engaging portion 30 is a portion engageable with a tip end portion of the turnbuckle lifting tool (in other words, a remote operation tool for lifting the turnbuckle 1A upward). In the example shown in fig. 1, the first engaging portion 30 is a through hole 30 h.

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 12 a. More specifically, the first engaging portion 30 is disposed below the first contact surface 11A and the second contact surface 12a while the postures of the first member 11 and the second member 12 are maintained such that the first contact surface 11A is positioned above the second contact surface 12a (in other words, the wire grip 1A is lifted by the wire grip lifting tool).

When the first engaging portion 30 is disposed below the first contact surface 11A and the second contact surface 12a, the wire grip lifting tool does not intersect the wire W in the step of inserting the wire W into the wire housing space SP between the first contact surface 11A and the second contact surface 12a (in other words, the step of mounting the wire grip 1A to the wire W). More specifically, in the step of attaching the wire grip 1A to the wire W, the portion that engages with the first engaging portion 30 in the wire grip lifting tool is always positioned below the wire W. Accordingly, the wire W does not interfere with the wire grip lifting tool, and the operation of attaching the wire grip 1A to the wire W can be smoothly performed.

Next, any additional configuration that can be employed in the wire grip 1A of the first embodiment will be described.

(first Member 11)

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

In the example shown in fig. 1, the first engaging portion 30 is disposed in the lower portion 112 of the first member 11. Therefore, in the step of mounting the wire grip 1A to the wire W, the wire W does not interfere with the wire grip lifting tool, and the work of mounting the wire grip 1A to the wire W can be smoothly performed.

Further, in the case where the first engaging portion 30 is provided at the first member 11 (more specifically, the lower side portion 112 of the first member 11), the positional relationship between the first engaging portion 30 and the first member 11 (more specifically, the first contact surface 11A) does not change in the step of attaching the wire grip 1A to the wire rod W. More specifically, the first engaging portion 30 does not swing with respect to the first member 11 when the first member 11 contacts the wire W. Accordingly, the work of attaching the wire grip 1A to the wire rod W can be smoothly performed. In contrast, for example, when the first engaging portion 30 is disposed on the swinging member 20, the first engaging portion swings together with the swinging member 20 with respect to the first member 11 because the first member 11 contacts the wire W. Due to this swing, there is a possibility that the work of attaching the wire grip 1A to the wire rod W is hindered.

(operating lever part 40)

The wire grip 1A according to the first embodiment may further include a lever member 40, and the lever member 40 may be coupled to the swing member 20 so as to be rotatable about the third axis AX 3. The wire grip 1A may further include a third pin member P3, and the third pin member P3 may rotatably connect the swing member 20 and the operating lever member 40. The third plug member P3 is disposed along the third axis AX 3.

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 can swing about the first axis AX 1. As the swing 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 electric wire W is gripped by the first member 11 and the second member 12. In the example shown in fig. 1, the second end 40b of the lever member 40 (the end connected to the opposite side of the first end of the swing member 20) is a free end. The free end portion is connected to, for example, a retractable rod member 70 described later. As shown in fig. 1, 2 or more through holes 40h may be formed in the second end portion 40b of the lever member 40 along the vertical direction. In this case, the position at which the second end portion 40b is connected to the rod member 70 may be switched in the vertical direction.

(guide part GA)

The turnbuckle 1A (more specifically, the first member 11) may also 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 provided at a rear side portion (a portion on the first direction DR1 side) of the first member 11. In the example shown in fig. 1, the guide portion GA extends to protrude below and rearward of the rear end of the first contact surface 11a (or the rear end of the second contact surface 12 a).

In the example shown in fig. 2, the guide portion GA includes a guide wall Gw for guiding the lever member 40. The guide wall Gw is a wall defining a through hole Gh through which the intermediate portion 43 (see fig. 1) of the lever member 40 is inserted, for example. The guide portion GA restricts the position of the lever member 40, thereby suppressing excessive positional displacement of the lever member 40 in the lateral direction (direction perpendicular to the paper surface of fig. 1), and as a result, suppressing excessive load from acting on the coupling portion between the lever member 40 and the swinging member 20.

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

When the first engaging portion 30 is disposed at the guide portion GA that guides the movement of the lever member 40, the first engaging portion 30 is disposed at a position sufficiently distant from the first contact surface 11a, the second contact surface 12a, and the swinging member 20. Therefore, the field of vision of the worker who attaches the wire grip 1A to the wire W can be suppressed from being obstructed by the wire grip lifting tool engaged by the first engaging portion 30.

(engaging part 42 of lever member 40)

The lever member 40 may also have an engaging portion 42, and the engaging portion 42 may be engaged with the guide portion GA (more specifically, the lower end portion 112 b). In the example shown in fig. 3, the engaging portion 42 is provided on the bottom surface 40s of the lever member 40. In the example shown in fig. 3, the engaging portion 42 is provided in the recess 40d of the bottom surface 40s of the lever member 40.

When the lever member 40 includes the engaging portion 42 engageable with the guide portion GA, the relative position between the lever member 40 and the guide portion GA can be maintained.

When the turnbuckle 1A is lifted by the turnbuckle lifting tool, the swing member 20 swings when the operating lever member 40 moves relative to the first member 11. As a result, the distance 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 distance between the first contact surface 11a and the second contact surface 12a is changed, the work of inserting the wire rod W into the wire rod housing space SP defined by the first contact surface 11a and the second contact surface 12a may be hindered.

In contrast, when the lever member 40 includes the engaging portion 42 engageable with the guide portion GA, the lever member 40 does not move relative to the first member 11 when the wire grip 1A is lifted by the wire grip lifting tool. Accordingly, the distance between the first contact surface 11a and the second contact surface 12a can be maintained at a constant distance, and the wire rod W can be smoothly inserted into the wire rod housing space SP defined by the first contact surface 11a and the second contact surface 12 a.

In the example shown in fig. 1, the engagement between the engagement portion 42 and the guide portion GA (more specifically, the lower end portion 112b) is maintained by the gravitational force acting on the lever member 40. In other words, when the lever member 40 is lifted against the gravity acting on the lever member 40, the engagement between the engaging portion 42 and the guide portion GA can be released.

(arrangement of first engaging portion 30)

In the example shown in fig. 1, the first engaging portion 30 is disposed at a rear side portion of the first member 11 (more specifically, a guide portion GA that guides the movement of the lever member 40). Alternatively, as shown in fig. 4, the first engaging portion 30 may be disposed on the front side portion 11f (more specifically, the end portion on the second direction DR2 side) of the first member 11. Further, when the first engaging portion 30 is disposed so as to protrude below and forward of the front end of the first contact surface 11A (or the front end of the second contact surface 12 a), the view of the worker who attaches the wire grip 1A to the wire W can be prevented from being obstructed by the wire grip lifting tool with which the first engaging portion 30 is engaged.

(shape or structure of the first engaging portion 30)

In the example shown in fig. 1 or 4, the first engaging portion 30 is a through hole 30 h. The central axis AX of the through hole 30h is parallel to the first axis AX 1. Alternatively, the central axis AX of the through hole portion 30h may be parallel to the first direction DR 1. When the first engaging portion 30 is a through hole 30h, the inner diameter of the hole is, for example, 13mm to 45 mm.

In the example shown in fig. 1 or 4, the first engaging portion 30 is constituted by the first engaging member 3 which is independent of the first member 11. Alternatively, the first engaging portion 30 may be integrally formed with the first member 11. In other words, the first engaging portion 30 may be formed by drilling the first member 11. Further, the first engaging member 3 may have a projection 32 (e.g., shoulder). 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 30 h). When a certain tightener lifting tool (for example, SHOTGUN train (manufactured by hastengs corporation) or SHOTGUN train (manufactured by AB change corporation)) is engaged with the first engaging portion 30, the first engaging member 3 (and the tightener 1A) can be prevented from being swung with respect to the tightener lifting tool when a part of the tightener lifting tool comes into contact with the protrusion 32. Accordingly, when the protruding portion 32 is provided in the first engaging member 3, the operation of bringing the wire grip 1A close to the wire W is facilitated. In the example shown in fig. 1, the protruding portion 32 protrudes in a direction away from a vertical surface Pa passing through the central axis AX of the through-hole 30 h. The protruding portion 32 includes a first protruding portion 32a and a second protruding portion 32b, and the protruding direction of the first protruding portion 32a is opposite to the protruding direction of the second protruding portion 32 b.

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

(locking member 50)

The wire grip 1A may be provided with a locking member 50. The lock member 50 is a member for maintaining a state in which the wire rod W is gripped between the first contact surface 11a and the second contact surface 12a, in other words, a member for defining a distance between the first contact surface 11a and the second contact surface 12 a.

In the example shown in fig. 1, a first portion 51 of the lock member 50 is attached to the first member 11, and a second portion (not shown) of the lock member 50 is attached to the swing member 20. The lock member 50 includes an operating portion 50a (e.g., an operating ring) and a threaded rod 50b for adjusting a distance between the first portion 51 of the lock member 50 and the second portion of the lock member 50, in addition to the first portion 51 attached to the first member 11 and the second portion attached to the swing member 20. Further, a thread screwed to the threaded rod 50b is formed on one of the first portion 51 and the second portion of the lock member 50. In addition, the screw thread screwed to the screw rod 50b is not formed in the other of the first portion 51 or the second portion of the lock member 50, in other words, a through hole through which the screw rod 50b is inserted is formed. Then, the screw rod 50b is rotated by rotating the operation portion 50a (e.g., operation ring) by the remote operation tool. When the threaded rod 50b is rotated, one of the first portion 51 and the second portion of the locking member 50 is screwed to the threaded rod 5b, so that the interval between the first portion 51 of the locking member 50 and the second portion of the locking member 50 is reduced, and the swing member 20 swings. The distance between the first contact surface 11a and the second contact surface 12a is reduced by the oscillation of the oscillating member 20, and the wire rod W is gripped between the first contact surface 11a and the second contact surface 12 a.

In a state where the wire W is already disposed between the first contact surface 11a and the second contact surface 12a, the holding state of the wire W by the first contact surface 11a and the second contact surface 12a can be maintained by operating the lock member 50. Further, the lock member 50 can restrict the swing member 20 from swinging in a direction in which the distance between the first contact surface 11a and the second contact surface 12a becomes larger. Therefore, the wire grip 1A can be prevented from being unintentionally detached from the wire W.

(second embodiment)

The wire grip 1B in the second embodiment is explained with reference to fig. 5 to 13. Fig. 5 is a schematic two-dimensional view schematically showing the wire grip 1B in the second embodiment. A schematic front view is shown on the right side of fig. 5, and a schematic side view is shown on the left side of fig. 5. In the left-hand side view (simplified side view) of fig. 5, the lock member 50 and the like are not described to avoid complication of the drawing. Fig. 6 is a schematic side view schematically showing the wire grip 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. Fig. 10 to 12 are schematic two-dimensional views schematically showing the wire grip 1B in the second embodiment. Schematic plan views are shown on the upper side of fig. 10 to 12, and schematic side views are shown on the lower side of fig. 10 to 12. Fig. 13 is a schematic side view schematically showing the wire grip 1B in the second embodiment.

The wire grip 1B according to the second embodiment includes the guide member 60, and the guide member 60 is a wire material accommodating space SP for guiding the wire material W between the first contact surface 11a and the second contact surface 12 a.

In the second embodiment, points different from those in the first embodiment will be mainly described, and redundant description of the items described in the first embodiment will be omitted. Accordingly, even if it is not explicitly described in the second embodiment, it is needless to say that the matters described in the first embodiment can be adopted in the second embodiment.

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

Since the first embodiment has been described for the first member 11, the second member 12, the swing member 20, and the lever member 40, the repeated description of the first member 11, the second member 12, the swing member 20, and the lever member 40 will be omitted.

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

The closing portion 61 is a portion that closes at least a part of the side portion of the wire housing space SP. The closing portion 61 prevents the wire W inserted into the wire housing space SP from coming off from the wire housing space SP.

The guide portion 62 is a portion that guides the wire rod W that presses the guide portion 62 to the wire rod housing space SP.

When the wire tightener 1B includes the closing portion 61 and the guide portion 62, the operation of inserting the wire rod W into the wire rod accommodating space SP between the first contact surface 11a and the second contact surface 12a becomes easy, and the wire rod W can be prevented from being detached from the wire rod accommodating space SP. As a result, the operation of attaching the wire grip 1B to the wire W becomes easier.

Next, any additional configuration that can be employed in the wire grip 1B of the second embodiment is described.

(overall shape of guide member 60)

In the example shown in fig. 6 and 7, the guide member 60 includes a first plate portion PL1 and a second plate portion PL2, the first plate portion PL1 includes the closing portion 61, and the second plate portion PL2 includes the guide portion 62. The first plate portion PL1 and the second plate portion PL2 are connected via a bent portion BN. The first plate portion PL1, the second plate portion PL2, and the bent portion BN may also be formed by bending 1 plate material.

In the example shown in fig. 6 and 7, the guide portion 62 and the closing portion 61 are formed of 1 piece by integral molding. In this case, the manufacturing cost of the guide member 60 can be reduced. However, the guide portion 62 and the closing portion 61 may be separate bodies, and the guide portion 62 may be attached to the closing portion 61.

As shown in fig. 8, the guide member 60 may be formed with a slit SL and/or a through-hole H for viewing the inside of the wire housing space SP from the outside thereof. When the guide member 60 has the slit SL or the through-hole H, the operator can easily confirm whether or not the wire rod W is properly arranged in the wire rod housing space SP. Alternatively, as shown in fig. 9, the guide member 60 may have a first guide member 60-1 and a second guide member 60-2, and the first guide member 60-1 and the second guide member 60-2 are disposed with a gap G therebetween. In this case, the operator can confirm whether the wire rod W is properly arranged in the wire rod housing space SP through the gap G.

(closing part 61)

In the example shown in fig. 10 and 11, the guide member 60 is configured to: when the guide portion 62 is pressed by the wire W, the closing portion 61 moves in a direction away from the wire housing space SP. Fig. 10 shows a state before the guide portion 62 is pressed by the wire W, and fig. 11 shows a state in which the guide member 60 is being pressed by the wire W.

With the above configuration, the wire rod W that has contacted the guide portion 62 is smoothly guided into the wire rod housing space SP (see arrow a in fig. 11).

In the example shown in fig. 11, the closing portion 61 is located at a first position where the wire rod W is allowed to be inserted into the wire rod housing space SP. When the closing portion 61 is located at the first position, the width of the opening OP between the inside of the wire housing space SP and the outside of the wire housing space SP (more specifically, the minimum distance between the lower end of the closing portion 61 and the second member 12) may be larger than the diameter of the wire W. Accordingly, the wire W can enter the wire housing space SP through the opening OP.

On the other hand, in the example shown in fig. 12, the closing portion 61 is located at the second position where the wire W is prevented from being detached from the wire housing space SP. When the closing portion 61 is located at the second position, the width of the opening OP is smaller than the diameter of the wire W. Accordingly, the wire W can be prevented from falling out of the wire housing space SP through the opening OP.

In the example shown in fig. 11 and 12, the position of the closing portion 61 is changeable between a first position (see fig. 11) that allows the wire rod W to be inserted into the wire rod housing space SP and a second position (see fig. 12) that prevents the wire rod W from being detached from the wire rod housing space SP. Accordingly, the work of inserting the wire rod W into the wire rod accommodating space SP becomes easy, and the wire rod W inserted into the wire rod accommodating space SP can be prevented from being separated from the wire rod accommodating space SP.

From the viewpoint of effectively preventing the wire W inserted into the wire housing space SP from being detached from the wire housing space SP, the closing portion 61 is preferably pressed in the direction from the first position (see fig. 11) toward the second position (see fig. 12).

In the example shown in fig. 11 and 12, the wire grip 1B includes a pressing member 68, and the closing portion 61 is pressed in a direction from the first position (see fig. 11) toward the second position (see fig. 12) by the pressing member 68. More specifically, one end of the pressing member 68 is supported by a guide member supporting member 69 attached to the first member 11, and the other end of the pressing member 68 is a base end configured to contact the guide member 60. Further, the guide member 60 (more specifically, the base end portion of the guide member 60) disposed between the guide member support member 69 and the first member 11 is pressed by the pressing member 68, thereby pressing the closing portion 61 in a direction from the first position toward the second position.

Further, from the viewpoint of being able to smoothly change the position of the closing section 61 between the first position and the second position, the guide member 60 is preferably able to change the posture between: a posture perpendicular to the shaft portion 69a of the guide member support member 69, and a posture (other than the perpendicular posture) inclined with respect to the shaft portion 69a of the guide member support member 69. The guide member 60 can change its posture with respect to the shaft portion 69a, and thus the closing portion 61 can be inclined in a direction away from the wire material accommodating space SP as it goes downward (see fig. 11). By this inclination, the width of the opening OP is enlarged. The guide member 60 can be changed in posture with respect to the shaft portion 69a, whereby the closing portion 61 can be formed parallel to the vertical direction (see fig. 12). When the closing portion 61 is parallel to the vertical direction, the width of the opening OP is reduced.

In order to allow the guide member 60 to change its posture with respect to the shaft portion 69a, the inner diameter of an insertion hole 60h (see fig. 7 and the like) formed in the guide member 60 is preferably sufficiently larger than the outer diameter of the shaft portion 69a inserted into the insertion hole 60 h. Further, the base end portion of the guide member 60 is preferably fitted with a gap between the head portion 69b of the guide member support member 69 and the first member 11. The distance between the head portion 69b of the guide member support member 69 and the first member 11 is larger than the thickness of the base end portion of the guide member 60, so that the base end portion of the guide member 60 can be inclined with respect to the shaft portion 69 a.

In the example shown in fig. 11, the number of the pressing members 68 that press the closing portion 61 in the direction from the first position toward the second position is 2, but the number of the pressing members 68 may be 1 or 3 or more.

In the example shown in fig. 11, the guide member 60 and the pressing member 68 for pressing the closing portion 61 are different members. Alternatively, the guide element 60 itself may also press the closing part 61 in the direction from the first position towards the second position. For example, in the case where the guide member 60 is a plate spring, the guide member 60 itself may press the closing portion 61 in a direction from the first position toward the second position.

As shown in fig. 13, a convex portion 610 may be provided on a surface of the closing portion 61 facing the wire material accommodating space SP. In the case where the convex portion 610 is provided in the closing portion 61, the wire W contacting the convex portion 610 is guided in a direction toward the center of the wire housing space SP. In this case, since the wire W is guided by the convex portion 610 in addition to the guide portion 62, the wire W is easily guided toward the center of the wire housing space SP.

(guide part 62)

In the example shown in fig. 6, the guide portion 62 has a base end portion 62a connected to the closing portion 61 and a tip end portion 62 b. The extending direction of the guide 62, in other words, the direction from the base end portion 62a toward the tip end portion 62b is a direction away from the wire material accommodating space SP.

In the example shown in fig. 6, the guide portion 62 includes a guide surface 62s that guides the wire W by contacting the wire W. Further, the guide surface 62s is an inclined surface inclined with respect to a surface perpendicular to the first axis AX 1. More specifically, when the closing portion 61 is located at the first position (see fig. 6), the guide surface 62s is inclined in a direction approaching the wire material accommodating space SP as it goes upward. Therefore, when the wire W contacts the guide surface 62s, the wire W is guided toward the wire housing space SP. The guide surface 62s may be a planar inclined surface or a curved inclined surface.

In the example shown in fig. 5, the wire grip 1B includes the first engaging portion 30 described in the first embodiment in addition to the guide member 60. Alternatively, the wire grip 1B may not include the first engaging portion 30.

(third embodiment)

The wire cutting tool 100 according to the third embodiment will be described with reference to fig. 14 and 15. Fig. 14 is a schematic front view schematically showing the wire cutting tool 100 according to the third embodiment. Fig. 15 is a schematic side view schematically showing an example of the wire support 90.

The wire cutting tool 100 according to the third embodiment includes a wire grip 1, a second wire grip 2, and a retractable rod member 70.

As the wire grip 1 of the wire cutting tool 100 in the third embodiment, the wire grip 1A in the first embodiment may be adopted, and the wire grip 1B in the second embodiment may be adopted.

The wire grip 1 is a tool for gripping a first portion of the wire W. Since the wire grip 1 has already been described in the first embodiment or the second embodiment, redundant description of the wire grip 1 will be omitted.

As the second wire grip 2 of the wire cutting tool 100 in the third embodiment, the wire grip 1A in the first embodiment may be used, the wire grip 1B in the second embodiment may be used, or another wire grip may be used.

The second wire grip 2 is a tool for gripping a second portion different from the first portion among the wire W. In the example shown in fig. 14, the second wire grip 2 includes a first member 11, a second member 12, a swing member 20, and a lever member 40. The second wire grip 2 may also have 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 already described in the first embodiment or the second embodiment, and therefore, redundant description of these configurations is omitted.

The second engaging portion 80 is a portion engageable with a tip end portion of the turnbuckle lifting tool (in other words, a remote operation tool for lifting the second turnbuckle 2 upward). In the example shown in fig. 14, the second engagement portion 80 is a through hole 80 h. The second engaging portion 80 has the same configuration as the first engaging portion 30. Accordingly, the overlapping description of the second engaging portion 80 will be omitted. In the description of the first engaging portion 30 of the first embodiment, the "first engaging member 3", the "first engaging portion 30", the "through hole 30 h", and the "second through hole 31 h" are respectively replaced with the "second engaging member 8", the "second engaging portion 80", the "through hole 80 h", and the "second through hole 81 h", to describe the second engaging portion 80.

In the example shown in fig. 14, the retractable rod member 70 is coupled to the wire grip 1 (more specifically, the second end 40b of the lever member 40 of the wire grip 1). The retractable rod member 70 is coupled to the second wire grip 2 (more specifically, the second end 40b of the lever member 40 of the second wire grip 2).

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

When the rod member 70 is contracted in the direction of the longitudinal axis L1 of the rod member in a state where the wire tightener 1 grips the first portion of the wire rod W and the second wire tightener 2 grips the second portion of the wire rod W, the distance between the wire tightener 1 and the second wire tightener 2 is reduced. As a result, the wire W is loosened at a portion between the wire grip 1 and the second wire grip 2.

The rod member 70 includes an outer member 71, an inner member 72, and an operating portion 73. The operating portion 73 is a portion for operating the relative movement of the inner member 72 with respect to the outer member 71. The operating portion 73 is connected to the rod member 70 and is rotatable about a fourth axis AX 4. The operation unit 73 includes an engagement portion 730 with which the distal end of the remote operation member is engaged.

An example of a mechanism for extending and retracting the retractable rod member 70 by using the remote operation member will be described. As an example, the following is conceivable: (A) the operating portion 73 is provided with a first bevel gear that is rotatable together with the operating portion about a fourth axis AX4, (B) the outer member 71 is provided with a second bevel gear that is connected to the first bevel gear so as to be able to transmit a load, (C) the second bevel gear is rotatable together with a threaded rod having a male thread disposed on the outer periphery thereof about the longitudinal axis L1 of the rod member 70, and (D) the inner member 72 is screwed to the threaded rod. In this case, when the operation portion 73 is rotated about the fourth axis AX4 by the remote operation member, the first bevel gear rotates about the fourth axis AX4, and the second bevel gear rotates about the longitudinal axis L1 of the bar member 70. When the second bevel gear is rotated about the longitudinal axis L1, the threaded rod is rotated about the longitudinal axis L1. When the threaded rod is rotated about the longitudinal axis L1, the inner member 72 screwed to the threaded rod moves in a direction in which it is pulled toward the outer member 71. In this way, the rod member 70 can be extended and contracted.

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

The rod member 70 is contracted to loosen the wire rod W (a part of the wire rod W) positioned between the wire grip 1 and the second wire grip 2, and then the wire rod cutting operation and the wire rod separating operation are performed. First, the slack portion of the wire W is cut by an arbitrary cutting tool. As a result, the first cut end and the second cut end are formed on the wire W. Next, the first cut end portion is separated from the second cut end portion (for example, separated in the up-down direction). The wire rod cutting work is completed through the above steps (more specifically, the step of contracting the rod member 70 in a state where the wire grip 1 grips the first portion of the wire rod W and the second wire grip 2 grips the second portion of the wire rod W, the step of cutting the slack portion of the wire rod W formed by the contraction of the rod member 70 with the cutting tool, and the step of separating the first cut end portion and the second cut end portion formed by the cutting).

The wire cutting tool 100 may also be provided with at least 1 wire support 90 from the viewpoint of efficiently performing the work of separating the first cut end portion from the second cut end portion.

The wire support 90 is a member that supports the wire W in a region between the wire grip 1 and the second wire grip 2. In the example illustrated in fig. 14, the wire cutting tool 100 includes a first wire support 90a and a second wire support 90 b. In the example shown in fig. 14, the first wire support 90a and the second wire support 90b are attached to the rod member 70.

In the example shown in fig. 15, the first wire support 90a has a housing space CP for housing the wire W. In the example shown in fig. 15, the number of the accommodating spaces CP of the first wire supporter 90a is 2, but the number of the accommodating spaces CP of the first wire supporter 90a may be 1, 3 or more. The first wire support 90a includes a frame member 91 and an opening/closing member 92, and the opening/closing member 92 can open and close the opening of the frame member 91. The opening/closing member 92 is connected to the operation unit 93, and the opening/closing member 92 can be switched from the closed state to the open state by operating the operation unit 93. When the opening and closing member 92 is in the open state, the operator can insert the wire W into the housing space CP of the first wire support 90a by using the remote operation tool. Further, when the opening and closing member 92 is in the open state, the worker can take out the wire W from the housing space CP of the first wire support 90a by using the remote operation tool.

When the first cut end portion and the second cut end portion of the wire rod are separated from each other, for example, the first wire rod supporter 90a may be rotated about the longitudinal axis L1 of the rod member 70 in a state where the wire rod connected to the first cut end portion is disposed in the housing space CP. Alternatively, the wire rod disposed in the first housing space CP1 may be moved to the second housing space CP2 by a remote operation tool, thereby performing the separation work.

In the example shown in fig. 14, the second wire support 90b includes a frame member 94 and an opening/closing member 95, and the opening/closing member 95 can open and close the opening of the frame member 94. The frame member 94 has the same structure as the frame member 91, and the opening/closing member 95 has the same structure as the opening/closing member 92. Accordingly, the overlapping description of the frame member 94 and the opening/closing member 95 will be omitted.

In the example shown in fig. 14, the first end 70a of the rod member 70 and the lever member 40 of the wire grip 1 are coupled so as not to be swingable, and the second end 70b of the rod member 70 and the lever member 40 of the second wire grip 2 are coupled so as not to be swingable. In this case, in a state where the first engaging portion 30 is engaged with the wire grip lifting tool and the second engaging portion 80 is engaged with the second wire grip lifting tool, the wire cutting tool 100 can be lifted by the wire grip lifting tool and the second wire grip lifting tool.

In the example shown in fig. 14, the first engaging portion 30 is disposed below the first contact surface 11a and the second contact surface 12a of the wire grip 1, and the second engaging portion 80 is disposed below the first contact surface 11a and the second contact surface 12a of the second wire grip 2. Therefore, the turnbuckle lifting tool and the second turnbuckle lifting tool do not interfere with the wire rod W, and the turnbuckle 1 and the second turnbuckle 2 can be mounted to the wire rod W relatively easily.

Alternatively or additionally, a guide member 60 may be mounted on the wire grip 1 of the wire cutting tool 100 in the third embodiment. The wire W that has contacted the guide portion 62 of the guide member 60 is guided to the wire housing space SP by the guide portion 62. In this case, the work of inserting the wire rod W into the wire rod housing space SP is easy. Further, the closing portion 61 of the guide member 60 prevents the wire rod W inserted into the wire rod accommodating space SP from being detached from the wire rod accommodating space SP. Accordingly, the operation of attaching the wire grip 1 to the wire rod W can be performed more reliably.

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

In the third embodiment, one of the turnbuckle 1 and the second turnbuckle 2 may be connected to the rod member 70 so as to be swingable about a swing shaft.

For example, consider a case where the lever member 40 of the wire grip 1 is swingably connected to the first end 70a of the rod member 70. In this case, the wire cutting tool 100 can be lifted by the turnbuckle lifting tool in a state where the first engaging portion 30 is engaged with the turnbuckle lifting tool. The first engaging portion 30 is disposed below the first contact surface 11a and the second contact surface 12a of the wire grip 1. Therefore, the turnbuckle lifting tool does not interfere with the wire W, and the turnbuckle 1 can be mounted to the wire W relatively easily. After the wire grip 1 is mounted to the wire W, the second wire grip 2 can be lifted up by using a remote operation tool. By this lifting action, the rod member 70 is rotated about the swing shaft with respect to the turnbuckle 1, and is lifted upward. After that, the second turnbuckle 2 is attached to the wire W.

The present invention is not limited to the above embodiments, and it is clear that the embodiments may be modified or changed as appropriate within the scope of the technical idea of the present invention. In addition, any of the components used in the embodiments may be combined with any of the other embodiments, and any of the components may be omitted in the embodiments.
