Description

[Technical field]

[0001] The present invention relates to technology relating to tools for compressing connecting tubes (so-called sleeves) for connecting cables and for cutting cables, and more specifically, to a cable compression and cutting device capable of performing both sleeve compression and cable cutting operations, and a cable cutting device capable of cutting cables. [Background technology]

[0002] Power plants generate electricity at several thousand to tens of thousands of volts, but to avoid losses due to electrical resistance, this electricity is converted to ultra-high voltage of around several hundred thousand volts before transmission. The voltage is then gradually reduced at each substation, such as ultra-high voltage substations, primary substations, secondary substations, and distribution substations, before being supplied to factories and other facilities, and the voltage is further reduced by pole-mounted transformers before being supplied to homes. In any case, electricity generated at power plants is supplied to users via cable-based transmission and distribution lines (hereinafter collectively referred to as "power transmission lines, etc."), and naturally, there are a great number of transmission lines, etc., deployed throughout the country.

[0003] Power lines and the like are wired by being strung on power poles or buried underground. Part of the cable may be replaced due to deterioration over time, and the wiring route of the power lines and the like may be changed depending on the user's situation. Usually, when carrying out such work, the cable is first cut and then reconnected. For example, Patent Document 1 discloses a technology for transferring a large-diameter existing electric cable by a camless method, and specifically proposes a "transfer method for a large-diameter existing electric cable" in which the electric cable is cut on the scaffolding of a new steel tower, a tension clamp is attached to the cut end, and the cut end is compressed by a compressor.

[0004] [Patent Document 1] JP 2012-50251 A Summary of the Invention [Problem to be solved by the invention]

[0005] As mentioned above, cable construction work for changing the wiring route of power transmission lines, etc., involves two tasks: "cutting work," in which the cable is cut, and "compression work," in which the sleeve is compressed to connect the cable. Cutting work requires the use of a dedicated cutting tool, and compression work requires the use of a dedicated compression tool. Therefore, even when cutting and compressing work are performed consecutively, workers must switch tools, which increases the amount of work required. Moreover, two types of tools must be kept at hand, but when working at height, there is sometimes not enough space to do so, and it can be difficult to arrange the tools so that they can be quickly changed.

[0006] Alternatively, the same tool may be used for both cutting and compression work, with different attachments. However, in this case, the attachment must be changed between cutting and compression, which increases the number of man-hours required. Furthermore, when working at height with a narrow working space, if the attachment falls during the change, it can result in a large loss of work and may even cause injury to third parties.

[0007] Furthermore, when cutting is performed using conventional cutting tools, the cable is cut in a manner that crushes it, so that not only are sharp cut surfaces not formed, but cutting operations cannot be performed smoothly.

[0008] The object of the present invention is to solve the problems associated with the prior art, i.e., to provide a cable compression cutting device that can perform cutting and compression operations without changing the tool itself or the tool attachments, and a cable cutting device that is more likely to produce sharper cut surfaces than the prior art. [Means for solving the problem]

[0009] The cable compression cutter of the present invention is based on an unprecedented idea that it has both a compression tool and a cutting tool, and that the compression tool and the cutting tool are mounted interchangeably. Also, the cable cutter of the present invention is based on an unprecedented idea that it sharply cuts the cable between the "side surface of the support tool" and the "back surface of the cutting blade".

[0010] The cable compression cutting device of the present invention is a device for compressing a cable sleeve and cutting the cable, and is equipped with a clamping body, a processing tool, an exchange means, a support tool, and an operating means. The clamping body has an opening groove formed between opposing "first surface" and "second surface", and the processing tool is housed on the first surface side of the clamping body. The exchange means exchanges the compression tool and the cutting tool included in the processing tool, the support tool is disposed on the second surface side of the clamping body, and the operating means extends the support tool. By operating the exchange means, the compression tool and the cutting tool are selectively disposed on the first surface side, and the operating means extends the support tool so as to approach the first surface. The compression tool has a circular arc-shaped "first abutment" on the tip surface, the support tool has a circular arc-shaped "second abutment" on the tip surface, and the cutting tool has a cutting blade. Then, when the compression jig is arranged on the first surface side by the replacement means and a portion of the cable sleeve arranged in the opening groove is in contact with the first abutment portion and the second abutment portion, the support jig is extended by the operating means, compressing the cable sleeve. Meanwhile, when the cutting jig is arranged on the first surface side by the replacement means and a portion of the cable arranged in the opening groove is in contact with the second abutment portion, the support jig is extended by the operating means, cutting the cable with the cutting blade.

[0011] The cable compression cutting device of the present invention may include two or more compression jigs in the processing jig. The two or more compression jigs are provided with arc-shaped first contact portions having different diameters. In this case, by operating the replacement means, one of the compression jigs is selectively positioned on the first surface side.

[0012] The cable compression cutting device of the present invention may be configured such that the compression jig is provided with two or more first contact portions, in which case the cable sleeve disposed in the open groove is compressed at two or more locations spaced apart in the axial direction of the cable sleeve.

[0013] The cable compression and cutting device of the present invention may be configured to include a rotating body in which the replacement means is disposed on the side of the clamping body. In this case, the compression tool and the cutting tool are selectively disposed on the first surface side by rotating the rotating body.

[0014] The cable compression and cutting device of the present invention may be configured so that characters or symbols representing the compression tool and the cutting tool are displayed on the rotating body. The characters or symbols are displayed on the rotating body using a light-reflective material.

[0015] The cable compression cutting device of the present invention may also be one in which a side wall surface is formed at the tip of the support jig. In this case, the cutting blade has a "back surface" arranged substantially parallel (including parallel) to the side wall surface, and an "inclined surface" inclined relative to the back surface, has a tapered shape in side view, and is arranged at a position where it does not come into contact with the support jig when extended. Then, when the support jig is extended by the operating means with a part of the cable arranged in the open groove abutting on the second abutment portion, the cable is cut between the side wall surface of the support jig and the back surface of the cutting blade.

[0016] The cable compression cutting device of the present invention may be one in which the cutting tool is provided with two or more cutting blades. In this case, two or more support tools are provided, and the cable placed in the open groove is cut at two or more locations separated in the axial direction of the cable.

[0017] The cable cutting device of the present invention is a device for cutting a cable, and includes a clamping body, a cutting blade, a support jig, and an actuating means. The second contact portion is formed on the tip surface of the support jig, and the cutting blade has a tapered shape having a back surface and an inclined surface. The cutting blade is positioned so that it does not come into contact with the support jig when extended. When the support jig is extended by the actuating means with a part of the cable placed in the open groove in contact with the second contact portion, the cable is cut between the side surface of the support jig and the back surface of the cutting blade. Effect of the Invention

[0018] The cable compression cutting device of the present invention has the following advantages. (1) When cutting and compressing are performed consecutively, the worker can perform each task without changing tools. As a result, the number of work steps can be reduced compared to the conventional technology. (2) Since there is no need to place other tools or attachments at your feet, work can be performed more easily and safely than in conventional techniques, even in a small work space. (3) Because cutting and compression can be performed with a single device, storage space and transport weight can be reduced compared to conventional technologies.

[0019] The cable cutting device of the present invention has the following advantages. (1) The cable is cut between the “side of the support jig” and the “back of the cutting blade,” so that a sharp cut surface can be formed on the cable. (2) In addition, since the cutting tool can cut sharply, cutting work can be performed more smoothly than with conventional tools. [Brief description of the drawings]

[0021] The present invention relates to a cable compression cutting device and a cable cutting device according to an embodiment of the present invention. For convenience, the term "cable" refers to various electrical conductors used in power transmission lines, power distribution lines, etc.

[0022] 1. Cable compression cutter First, the cable compression cutting device of the present invention will be described in detail with reference to the drawings. The cable cutting device of the present invention is configured including the main elements of the cable compression cutting device of the present invention. Therefore, the cable compression cutting device of the present invention will be described first, and then the cable cutting device of the present invention will be described.

[0023] 1 is a side view showing the entirety of a cable compression cutting device 100 according to the present invention. As shown in this figure, the cable compression cutting device 100 according to the present invention can be configured to include a clamping body 200 and a main body 600. Of these, the main body 600 houses an actuator (hereinafter referred to as "operating means") therein, and is also provided with a handle 610 for an operator to grasp, a switch 620 for acting on the operating means, and the like.

[0024] 2 is a side view showing the clamping body 200 constituting the cable compression cutting device 100, where (a) shows a state before a "support jig 400" described later is extended, and (b) shows a state in which the support jig 400 is extended. As shown in this figure, the clamping body 200 is provided with an open groove 210 formed between a first surface 220 and a second surface 230 opposed to each other, and a processing jig 300 is disposed on the first surface 220 side, and a support jig 400 is disposed on the second surface 230 side.

[0025] As can be seen by comparing FIG. 2(a) and FIG. 2(b), the support jig 400 extends (to the left in the figure) in the open groove 210 so as to approach the first surface 220. For example, when an operator operates the switch unit 620, the operating means can extend the support jig 400. Of course, the operating means can also return the support jig 400 to its original state (the state in FIG. 2(a)) by operating a "return lever" or the like. For convenience, the direction in which the support jig 400 moves (left-right direction in FIG. 2) is referred to as the "telescopic axis direction," and the axial direction perpendicular to this telescopic axis direction (depth direction of the paper in FIG. 2) is referred to as the "cable axial direction." Also, as shown in FIG. 1, the direction approaching the first surface 220 in the telescopic axis direction is referred to as the "forward direction," and the direction approaching the second surface 230 in the telescopic axis direction is referred to as the "rearward direction." In other words, when the operator operates the switch portion 620, the support jig 400 moves "forward," and when the operator operates the return lever, the support jig 400 moves "backward."

[0026] FIG. 3 is a schematic diagram of the support jig 400, where (a) is a side view and (b) is a front view seen from the first surface 220 side. As shown in this figure, a concave second abutment portion 401 is formed on the tip surface of the support jig 400 (the surface on the left side in the figure). This second abutment portion 401 is for accommodating the cable sleeve SL and a part of the cable, and therefore the second abutment portion 401 is formed to have an arc shape when viewed from the side. Furthermore, as shown in FIG. 3(b), the support jig 400 has a structure having a certain width dimension in the cable axial direction, and therefore the second abutment portion 401 may also be formed to have a certain width dimension in the cable axial direction. Furthermore, side wall surfaces 402 are formed on the left and right sides of the tip of the support jig 400. These side wall surfaces 402 have flat surfaces and are arranged so as to be approximately parallel (including parallel) to the telescopic axis direction.

[0027] As shown in Fig. 4, the processing jig 300 includes a "compression jig 310" used for compressing the cable sleeve SL, and a "cutting jig 320" used for cutting the cable. Fig. 4 is a side view showing the clamping body 200 in which each of the processing jigs 300 is arranged on the first surface 220, (a) showing a state in which the compression jig 310 is arranged, and (b) showing a state in which the cutting jig 320 is arranged. As shown in this figure, the compression jig 310 and the cutting jig 320 are arranged on the first surface 220 so as to take turns, and the replacement means 500 is used to carry out this replacement.

[0028] The replacement means 500 can be configured to include, for example, a rotating body 510 and a gripping portion 520 arranged on the side of the clamping body 200. In this case, when an operator rotates the rotating body 510 while holding the gripping portion 520, the selected compression jig 310 or cutting jig 320 is arranged on the first surface 220. Therefore, the compression jig 310 or cutting jig 320 is accommodated inside the front (first surface 220 side) of the clamping body 200. In other words, by rotating the rotating body 510, when the compression jig 310 is arranged on the first surface 220, the cutting jig 320 is accommodated in the clamping body 200, and when the cutting jig 320 is arranged on the first surface 220, the compression jig 310 is accommodated in the clamping body 200.

[0029] On the surface of the replacement means 500, "letters (kanji, kana, etc.)" or "symbols (numbers, alphabets, figures, etc.)" indicating the type of processing jig 300 can be displayed. This allows the operator to intuitively understand which processing jig 300 is placed on the first surface 220. In this case, it is preferable to display the letters and symbols using a light-reflective material such as fluorescent paint so that they can be seen even at night. For example, in FIG. 4, the compression jig 310 is displayed as "A" or "B," and the cutting jig 320 is displayed as "off." Note that the processing jig 300 can be configured to include two or more types of compression jigs 310 as described later, and in that case, it is preferable to display symbols (A and B in FIG. 4) that identify each compression jig 310 as shown in FIG. 4.

[0030] The gripping portion 520 may have a stopper function. For example, a screw may be provided in the gripping portion 520, so that when the gripping portion 520 is tightened, the rotation of the rotating body 510 is restricted, and when the gripping portion 520 is loosened, the rotating body 510 is allowed to rotate freely.

[0031] As described above, the cable compression cutting device 100 of the present invention can selectively arrange the compression jig 310 and the cutting jig 320 on the first surface 220 by operating the replacement means 500. In other words, the cable compression cutting device 100 of the present invention can be used as a tool for compressing the cable sleeve SL, and can also be used as a tool for cutting the cable.

[0032] FIG. 5 is a diagram showing the clamping body 200 when compressing the cable sleeve SL, (a) is a side view thereof, and (b) is a perspective view thereof. As shown in this figure, when the clamping body 200 is used for compressing the cable sleeve SL, a compression tool 310 is placed on the first surface 220. FIG. 6 is a diagram showing the compression tool 310 in a schematic manner, (a) is a side view thereof, and (b) is a front view seen from the second surface 230 side. As shown in this figure, a concave first abutment portion 311 is formed on the tip surface (the surface on the right side in the figure) of the compression tool 310. This first abutment portion 311, like the second abutment portion 401, is for accommodating a part of the cable sleeve SL and the cable, and therefore the first abutment portion 311 is formed so as to have an arc shape when viewed from the side. In addition, the support jig 400 has a structure having a certain width dimension in the cable axial direction as shown in FIG. 6(b), and therefore the first abutment portion 311 should also be formed to have a certain width dimension in the cable axial direction.

[0033] Figure 7 is a step diagram showing the procedure for compressing a cable sleeve SL using the cable compression cutting device 100 of the present invention, and is a plan view viewed from above, where (a) shows a state in which a portion of the cable sleeve SL placed in the opening groove 210 abuts only against the second abutment portion 401, and (b) shows a state in which a portion of the cable sleeve SL abuts against both the first abutment portion 311 and the second abutment portion 401.

[0034] When compressing the cable sleeve SL using the cable compression cutting device 100, first, the replacing means 500 is operated to place the compression jig 310 on the first surface 220, and the cable sleeve SL with the cable CB inserted from both sides is placed in the open groove 210, with a part of the cable sleeve SL (the right side in the figure) abutting against the second abutment portion 401. Next, the operator operates the switch unit 620, which causes the operating means to extend the support jig 400, i.e., the cable sleeve SL gradually moves forward. Then, when the cable sleeve SL is sandwiched between the first abutment portion 311 and the second abutment portion 401 and the support jig 400 further moves forward, the cable sleeve SL is compressed.

[0035] As described above, the processing jig 300 may be configured to include two or more types of compression jigs 310. In this case, it is preferable to select two or more types of compression jigs 310 each having an arc-shaped first abutment portion 311 with a different diameter. For example, in FIG. 8, a compression jig 310 (left side in the figure) provided with a first abutment portion 311 that is an arc with a large diameter and a compression jig 310 (right side in the figure) provided with a first abutment portion 311 that is an arc with a small diameter are prepared. This allows a relatively large diameter (for example, 14 to 22 cm 2 In the case of a cable sleeve SL of 2.6 cm, a compression tool 310 (left side in FIG. 8) having a first contact portion 311 of a large diameter arc is placed on the first surface 220, while a cable sleeve SL of a normal diameter (e.g., 2.6 cm) is placed on the first surface 220. 2 Or 3.2 cm 2In the case of a cable sleeve SL of a type (such as a cable sleeve SL of a type 100 or 120), a compression jig 310 (on the right in the figure) having a first contact portion 311 of a small diameter arc can be disposed on the first surface 220. When the processing jig 300 includes two or more types of compression jig 310, it is advisable to display a symbol or the like that identifies each compression jig 310. For example, as shown in Fig. 4, an "A" is displayed for a compression jig 310 (on the left in Fig. 8) having a first contact portion 311 of a large diameter arc, and a "B" is displayed for a compression jig 310 (on the right in Fig. 8) having a first contact portion 311 of a small diameter arc.

[0036] The cable sleeve SL may be compressed at a plurality of locations spaced apart in the axial direction. In this case, the cable compression cutting device 100 is moved along the cable sleeve SL while performing the operation, so that the cable sleeve SL can be compressed at a plurality of locations. Alternatively, the compression tool 310 may be provided with two or more first contact parts 311, so that the cable sleeve SL can be compressed at a plurality of locations in one operation. In this case, the compression tool 310 may be configured to include two or more (two in the figure) individual compression tools 310S as shown in FIG. 9. These individual compression tools 310S are arranged at intervals in the cable axial direction, and each of the individual compression tools 310S has an arc-shaped first contact part 311 on its tip surface. Due to the effect that the compression tool 310 includes two or more individual compression tools 310S, the cable sleeve SL can be compressed at two or more locations (two locations in the example of FIG. 9) in one operation.

[0037] FIG. 10 is a diagram showing the clamping body 200 when cutting the cable CB, (a) being a side view thereof, and (b) being a perspective view thereof. As shown in this figure, when the clamping body 200 is used for cutting the cable CB, a cutting tool 320 is disposed on the first surface 220. FIG. 11 is a diagram showing the cutting tool 320 in a schematic manner, (a) being a plan view seen from above, and (b) being a plan view seen from above of the cutting tool 320 and the extended support jig 400. As shown in this figure, the cutting tool 320 is provided with a cutting blade 321. The cutting blade 321 is formed with a back surface 321B and an inclined surface 321T inclined relative to the back surface 321B, and has a tapered shape that tapers off in a side view. Although FIG. 11 shows an example in which two types of inclined surfaces 321T are formed so that the angle changes along the way, the cutting blade 321 may be formed with only one type of inclined surface 321T, or may be formed with three or more types of inclined surfaces 321T.

[0038] The back surface 321B of the cutting blade 321 is a flat surface disposed approximately parallel (including parallel) to the side wall surface 402 of the support jig 400. As shown in Fig. 11(b) , the cutting blade 321 is disposed at a position where it does not come into contact with the support jig 400 when extended, and is disposed so that the back surface 321B of the cutting blade 321 and the side wall surface 402 of the support jig 400 are in contact with each other or so that an extremely small gap is provided.

[0039] FIG. 12 is a step diagram showing the procedure for cutting a cable CB using the cable compression cutting device 100 of the present invention, and is a plan view seen from above, where (a) shows a state in which a part of the cable CB arranged in the opening groove 210 is abutting only against the second abutment portion 401, and (b) shows a state in which the cable CB has been cut.

[0040] When cutting the cable CB using the cable compression cutting device 100, first, the cutting tool 320 is placed on the first surface 220 by operating the replacement means 500, and the cable CB is placed in the opening groove 210, and a part of the cable CB (the right side in the figure) is brought into contact with the second contact portion 401. Next, the operator operates the switch portion 620, which causes the operating means to extend the support jig 400, i.e., the cable CB gradually moves forward. Then, when the cable CB comes into contact with the cutting blade 321 and the support jig 400 further moves forward, the cable CB is cut between the back surface 321B of the cutting blade 321 and the side wall surface 402 of the support jig 400. When the cable CB is cut using a conventional cutting tool, the cable CB is cut in a manner that crushes it, so that a sharp cut surface is not formed and the cutting operation cannot be performed smoothly. In contrast, when cutting the cable CB using the cable compression cutting device 100, the cable CB is cut between the back surface 321B of the cutting blade 321 and the side wall surface 402 of the support jig 400, so that the cable CB can be cut while forming a sharp cut surface without crushing the cable CB, and therefore the cutting operation can be performed smoothly.

[0041] The cable CB may be cut at a plurality of points separated in the axial direction. In this case, the cable compression cutting device 100 is moved along the cable CB while performing the work, so that the cutting work can be performed at a plurality of points. Alternatively, as shown in FIG. 13, the cutting tool 320 may be provided with two or more individual cutting blades 321S, so that the cutting work can be performed at a plurality of points in one operation. FIG. 13 is a plan view of the cutting tool 320 provided with two individual cutting blades 321S, as seen from above. In this case, the support jig 400 may be configured to include two or more (two in the figure) individual support jigs 400S. This individual support jig 400S has the same configuration as the support jig 400, that is, a second abutment portion 401 is formed on the tip surface, and side wall surfaces 402 are formed on the left and right sides of the tip.

[0042] The two or more individual cutting blades 321S are arranged at intervals in the cable axial direction, and similarly the two or more individual support jigs 400S are arranged at intervals in the cable axial direction. Of course, the individual cutting blades 321S are arranged at positions where they do not come into contact with the individual support jig 400S when extended, and are arranged so that the back surface 321B of the individual cutting blade 321S contacts the side wall surface 402 of the individual support jig 400S (or so that an extremely small gap is provided). In this way, due to the effect that the cutting jig 320 has two or more individual cutting blades 321S, the cable CB can be cut at two or more locations (two locations in the example of FIG. 13) in one operation.

[0043] 2. Cable cutting device Next, the cable cutting device of the present invention will be described. The cable cutting device of the present invention is configured by including the main elements of the cable compression cutting device 100 described so far. Therefore, we will avoid overlapping explanations with those of the cable compression cutting device 100, and will only describe the contents unique to the cable cutting device of the present invention. In other words, the contents not described here are the same as those described in "1. Cable compression cutting device".

[0044] The cable cutting device of the present invention can be configured to include a clamping body 200 and a main body 600, similar to the cable compression cutting device 100. The main body 600 stores an operating means therein and is equipped with a handle 610, a switch 620, and the like. The clamping body 200 is provided with an opening groove 210, a cutting tool 320 is disposed on the first surface 220 side, and a support tool 400 is disposed on the second surface 230 side. The support tool 400 extends so as to approach the first surface 220 within the opening groove 210, and when an operator operates the switch 620, for example, the operating means extends the support tool 400. Of course, the operating means can also be configured to return the support tool 400 to its original state by operating a "return lever" or the like. A circular arc-shaped second abutment portion 401 is formed on the tip surface of the support tool 400, and side wall surfaces 402 are formed on the left and right sides of the tip.

[0045] The cutting tool 320 is provided with a cutting blade 321 having a back surface 321B and an inclined surface 321T. The back surface 321B of the cutting blade 321 is a flat surface arranged substantially parallel (including parallel) to the side wall surface 402 of the support jig 400. The cutting blade 321 is arranged at a position where it does not come into contact with the support jig 400 when extended, and is arranged so that the back surface 321B of the cutting blade 321 and the side wall surface 402 of the support jig 400 are in contact with each other or so that an extremely small gap is provided. The cutting tool 320 can also be provided with two or more individual cutting blades 321S. In this case, the support jig 400 may be configured to include two or more individual support jigs 400S. By providing the cutting tool 320 with two or more individual cutting blades 321S in this way, the cable CB can be cut at two or more locations in one operation.

[0046] When cutting the cable CB using the cable cutting device of the present invention, the cable CB is first placed in the open groove 210 with a part of the cable CB abutting against the second abutment portion 401. Next, the operator operates the switch portion 620, which causes the operating means to extend the support jig 400, i.e., the cable CB gradually moves forward. Then, when the cable CB comes into contact with the cutting blade 321 and the support jig 400 moves further forward, the cable CB is cut between the back surface 321B of the cutting blade 321 and the side wall surface 402 of the support jig 400.
