Description

Technical Field

[0001] The present invention relates to an electric wire clip capable of gripping and fixing an electric wire of a distribution line by indirect live-line work. More specifically, it is coupled to a tensioner, and using an indirect live-line work stick, in indirect live-line work, the electric wire is gripped and fixed, and can be opened and closed with a small force by a joint slide method. After the electric wire is fixed, when tension is generated, it can prevent the rotational play of the electric wire clip, and can stably grip and fix the electric wire in proportion to the magnitude of the tension, and relates to a joint slide lever link type electric wire clip having the function of an opening and closing operation grip guide for indirect live-line work and an electric wire fixing method using the same.

Background Art

[0002] Generally, live-line work refers to line work carried out while continuing power transmission to an electric wire line. Since live-line work has a very high risk of safety accidents, it is carried out when it is difficult to cut off power like in power transmission and distribution equipment, and workers performing direct live-line work must always use insulating protective gear or protective equipment.

[0003] The live-line work of an electric wire line includes work such as inspecting, repairing, replacing, and cleaning electric wire line components such as insulators, and can be classified into direct live-line work and indirect live-line work. Indirect live-line work is a method of working indirectly using an insulating tool such as a hot stick. Indirect live-line work has the advantage of being safe, but has the disadvantage of taking a long time.

[0004] Direct live-line work is a method in which an operator wears insulating gloves in an insulated bucket and then performs direct contact work in a live state. Direct live-line work is simple and the work time is reduced, but on the other hand, it has the disadvantage of a high risk of electric shock accidents and frequent occurrence of human life damage.

[0005] With the strengthening of safety management in industrial sites, since the Korea Electric Power Corporation declared the abolition of direct live-line work after 2016, the import of tools for indirect live-line work from overseas has increased, and the movement of domestic development has also increased.

[0006] On the other hand, tensioners are widely used in various live-line operations. Tensioners are devices used to pull on electric wires to create an appropriate dip in live-line operations, and for indirect live-line operations, indirect live-line tensioners are extremely important.

[0007] An example of such a wire tensioner is disclosed in Korean Patent No. 10-1179056 and Korean Utility Model Registration No. 20-0355330. Here, the wire tensioner includes a wire tensioner fixing device having a hook, a wire winding device having a drum connected to the lower side of the wire tensioner fixing device, a wire tensioner belt wound around the drum, a ratchet wheel positioned on one side of the wire winding device and coaxially connected to the drum to cause the drum to rotate in only one direction, a ratchet rotatably mounted on one side of the wire winding device where the ratchet wheel is located, with one end engaging with the ratchet wheel, a handle connected coaxially to the ratchet wheel for rotating the ratchet wheel and the drum, and a wire gripper (clip) connected to the free end of the wire tensioner belt for gripping the wire.

[0008] However, conventional wire clips are heavy and have complex manufacturing processes, making them almost impossible to apply to indirect live-line work on-site due to the labor intensity and physical limitations. Most of them use a hinge rotation structure that uses the tensile force of a tensioner belt to press and secure the wire, but this inevitably requires workers to operate the handles in close proximity to power lines, making it impossible to ensure worker safety. As a result, safety accidents have frequently occurred because workers must directly touch the wires while working.

[0009] Furthermore, since the clips of conventional tensioners, as described above, have a link structure, their durability was limited due to their ability to support considerable loads.

[0010] Furthermore, since the work involves repeated manual operation to secure and grip the power lines, performing this work directly on live lines is quite dangerous and inconvenient, leading to accumulated fatigue among workers and prolonged working hours.

[0011] Therefore, in order to solve the above-mentioned problems, the applicant of the present invention has proposed a sharp-angle guide-driven wire clip for a tensioner that enables indirect live-line work, as published in Korean Patent No. 10-2162545.

[0012] However, conventional wire clips, as described above, have upper and lower wire grippers for gripping the wire attached to guide pins and configured to slide along sharp-angled guide holes. As a result, when opening them using an indirect live-line work stick, a considerable amount of force is consumed, which is a problem.

[0013] Furthermore, since the aforementioned wire clips have upper and lower wire grippers attached to guide pins, there was a problem in that rotational vibration occurred when tension was applied to the wire. [Prior art documents] [Patent Documents]

[0015] The present invention was devised to solve the various problems described above, and the object of the present invention is to provide an articulated slide lever link type wire clip and a wire fixing method using the same, which have the function of an indirect live-line opening and closing operation grip guide for indirect live-line work, where the body slides to press and release the pressing gripper by pressing the operating pin with an indirect live-line work stick, thereby ensuring a sufficient safety distance from the wire, and allowing the wire to be gripped in proportion to the amount of tension, thereby preventing safety accidents in advance and conveniently fixing the wire in proportion to the amount of tension.

[0016] Furthermore, by configuring the device to allow rotation and vertical movement of only the pressing gripper via joint sliding action, the object of the present invention is to provide an articulated slide lever link type wire clip that has the function of an indirect live-line opening and closing operation grip guide that improves durability through improved operating structure and allows the gripper to be released with little force, and a wire fixing method using the same.

[0017] Furthermore, an object of the present invention is to provide an articulated slide lever link type electric wire clip that has the function of an indirect live-line opening and closing operation grip guide, and an electric wire fixing method using the same, in which the support gripper is fixedly configured on the electric wire clip body, thereby preventing rotational movement by the fixed support gripper when gripping and fixing the electric wire, and enabling stable gripping and fixing of the electric wire in proportion to the amount of tension. [Means for solving the problem]

[0018] A specific means for achieving the above objective is a clip that is connected to a tensioner and can grip an electric wire,

[0019] A wire clip body has a first axis formed at the front upper part, a support gripper formed at the front lower part, and an opening / closing plate support pin protruding from the front at the middle upper part,

[0020] A joint slide guide that is coupled to the wire clip body, guides the forward and backward sliding of the wire clip body, has a wire tensioner coupling portion formed at the rear portion, and a second axis formed at the upper portion, and

[0021] A link portion that connects the first axis and the second axis, and

[0022] A pressing gripper that is formed to correspond to the support gripper, is connected to the link portion via a fourth axis, moves up and down by the operation of the link portion, is elastically provided to the link portion via a pressing spring, applies a pressing force to the support gripper, and grips and fixes the wire, and

[0023] An automatic opening and closing plate that is connected to the link portion via a fourth axis, moves up and down and rotates, is elastically provided to the link portion via an opening and closing spring, and prevents the wire gripped between the support gripper and the pressing gripper from detaching, and

[0024] A pair of opening and closing operation grips formed on the rear surface of the wire clip body and the joint slide guide respectively, for moving the wire clip body, and

[0025] The link portion

[0026] A rotating portion in which the center is connected via the first axis, rotates up and down, one end of a restoring spring surrounding the first axis is fixed to the upper portion, the other end is fixed to the wire clip body, and rotational elasticity is imparted downward, and

[0027] A connecting portion in which the rear end is connected via the second axis, the front end is drawn forward, and is connected to the upper portion of the rotating portion via a third axis, and

[0028] When the wire clip body slides in a joint manner using the joint slide guide as a guide, the link portion operates in a joint manner and is configured to open and close between the support gripper by the up and down movement of the pressing gripper, and

[0029] Using an articulated slide lever link type wire clip that functions as an indirect live-line opening / closing operation grip guide, when performing wire sag adjustment, wire tensioning, wire mounting work, or suspension insulator replacement work during indirect live-line work on distribution lines, the wire is gripped and secured.

[0030] A preparatory step for connecting an articulated slide lever link type wire clip, which has the function of an indirect live-line opening / closing operation grip guide, to a tensioner via a tensioner coupling part,

[0031] A wire tensioner installation process involves installing a wire tensioner, which is fitted with an articulated slide lever link type wire clip that functions as an indirect live-line opening / closing grip guide, onto a utility pole using an indirect live-line work stick, and

[0032] A wire fixing process in which the opening and closing operation grip of an articulated slide lever link type wire clip, which has the function of an indirect live-line opening and closing operation grip guide connected to a wire tensioner, is operated with an indirect live-line work stick, and the wire is gripped and fixed using the support gripper and pressure gripper of the wire clip body, thereby preventing the wire from coming loose,

[0033] The main work process for power distribution lines involves operating a tensioning device to perform tasks such as adjusting the sag of power distribution line wires, tightening power lines, overhead wire installation, or replacing suspension insulators.

[0034] After the completion of the main work on the power distribution line, the wire separation process involves releasing the wire fixing force of the support gripper and the pressure gripper, and separating the articulated slide lever link type wire clip, which has the function of an indirect live-line opening and closing operation grip guide, from the wire.

[0035] This can be achieved by including a process of removing the tensioning device installed on a utility pole. [Effects of the Invention]

[0036] As described above, the articulated slide lever link type wire clip having the function of an indirect live-line opening and closing grip guide and the wire fixing method using the same according to the present invention allows the articulated slide guide to slide when the operating pin is pressed using an indirect live-line work stick, and the wire can be gripped and fixed in proportion to the amount of tension by the pressing and releasing operation of the pressing gripper. Therefore, it is possible to easily open the gripper or grip the wire using an indirect live-line work stick while ensuring a sufficient safety distance from the wire, thereby preventing safety accidents during long-distance indirect live-line work and enabling convenient wire fixing work.

[0037] Furthermore, since only the pressure gripper is configured to be pressed by joint action, the simplification of the structure and operation further improves durability, and the gripper can be released with little force, resulting in convenience of operation and the ability to perform quick and convenient wire fixing work.

[0038] Furthermore, by fixing the support gripper to the wire clip body, it becomes possible to obtain the effect of stably gripping and fixing the wire without any movement when gripping it. [Brief explanation of the drawing]

[0042] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] As shown in Figures 1 to 5, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, is a clip that is connected to a tensioner and used to grip and fix a wire in proportion to the magnitude of the tension when a tensioner is used in indirect live-line work on a power distribution line during processes such as adjusting the sag of a live-line power distribution line wire, wire tensioning work, wire overhead line work, or suspension insulator replacement work, and consists of a wire clip body 100, an articulated slide guide 200, a link part 300, a pressing gripper 400, an automatic opening / closing plate 500, and opening / closing operation grips 600, 600'.

[0045] First, the wire clip body 100 is configured to form the basis of the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening and closing operation grip guide according to the present invention, and is configured in the form of a vertical plate-type block having a length in the front-to-back direction, with the right side forming the front in the drawing.

[0046] For this purpose, in the present invention, the wire clip body 100 is configured such that a first shaft 101 can be connected to the front upper part of the link section 300, which will be described later.

[0047] Furthermore, the wire clip body 100 is provided with a support gripper 110 protruding from the front lower part, particularly on the front side, which can grip and secure the wire together with the pressure gripper 400 described later.

[0048] In this invention, the support gripper 110 is configured to have a length, and a semicircular wire arrangement groove 111 for arranging electric wires is formed on its upper surface, and the wire arrangement groove 111 is configured with sawtooth-shaped lower grooves 112 to prevent the gripped electric wires from slipping.

[0049] Furthermore, the wire clip body 100 is provided with an opening / closing plate support pin 120 protruding from the front, particularly at the upper middle section of its front surface, so as to be able to support the automatic opening / closing plate 500 (described later) when it is opened.

[0050] The articulated slide guide 200, in the configuration of the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening and closing operation grip guide according to the present invention, is connected to a normal tensioner and is slidably connected to the wire clip body 100, and is configured as a block shape having a length in the front-to-back direction to guide the sliding of the wire clip body 100 forward and backward.

[0051] For this purpose, the joint slide guide 200 is configured with a tensioner coupling portion 210 having a tensioner fastening hole 211 formed behind it.

[0052] Furthermore, a second shaft 201 is provided on the upper part of the joint slide guide 200 for connecting the first shaft 101 of the wire clip body 100 with the link portion 300.

[0053] On the other hand, in the present invention, the wire clip body 100 and the joint slide guide 200 are configured to slide firmly without any looseness during their sliding operation.

[0054] To this end, a guide pin 130 is first provided protruding from the upper rear side of the wire clip body 100.

[0055] Then, a first guide hole 140, which is a horizontally elongated hole extending towards the rear, is provided through the upper center.

[0056] Furthermore, the joint slide guide 200 is configured to surround the upper part of the wire clip body 100 in a "U" shape that opens downwards in cross-section, and a second guide hole 220 in the shape of a horizontal elongated hole is provided in the middle part through which the guide pin 130 passes.

[0057] Furthermore, a guide member 230 is provided on the front side of the joint slide guide 200, which is housed in the first guide hole 140 and can slide.

[0058] Therefore, when a tensile force is applied to the rearward direction, the wire clip body 100 is configured to slide back and forth guided by the first guide hole 140 and the guide member 230, and the second guide hole 220 and the guide pin 130.

[0059] In the configuration of the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide according to the present invention, the link portion 300 is configured to operate in an articulated manner as the wire clip body 100 slides, thereby opening and closing the pressure gripper 400 and the automatic opening / closing plate 500, which will be described later, by connecting the first shaft 101 and the second shaft 201.

[0060] For this purpose, the link section 300 first includes a triangular rotating section 310 that operates the pressure gripper 400 and the automatic opening / closing plate 500, which will be described later.

[0061] Here, the rotating part 310 is configured to rotate in an articulated manner, with its center connected via the first axis 101.

[0062] Furthermore, a restoring spring 311 is elastically installed in the rotating part 310, surrounding the first shaft 101. The restoring spring 311 is configured to have downward rotational elasticity by having one end fixed to the wire clip body 100 and the other end fixed to the upper part of the rotating part.

[0063] Furthermore, the link portion 300 is provided with a connecting portion 320 that rotates in the articulation manner of the rotating portion 310 during the sliding operation of the electric wire clip body 100.

[0064] Here, the connecting portion 320 is configured such that its rear end is connected via the second shaft 201, its front end is pulled forward, and it is connected to the upper part of the rotating portion 310 via the third shaft 301.

[0065] On the other hand, in the present invention, as described above, the third shaft 301 connecting the rotating part 310 and the connecting part 320 is configured to be at a position a predetermined height higher than the second shaft 201 when the wire clip body 100 is moved to its maximum forward position, so that when the wire clip body 100 moves backward, the connecting part 320 rotates upward in an articulated manner with the second shaft 201 as the axis.

[0066] Therefore, when the wire clip body 100 moves backward, the rotating part 310 is configured to rotate clockwise around the first shaft 101 and rotate upward in an articulated manner due to the action of the connecting part 320 pulling the upper part of the rotating part 310.

[0067] In the configuration of the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening and closing operation grip guide according to the present invention, the pressing gripper 400 is configured to open and close between itself and the support gripper 110 by the operation of the link portion 300, allowing the wire to enter and exit.

[0068] For this purpose, the pressing gripper 400 is in the form of a triangular block and is configured to have a length corresponding to the support gripper 110. The bottom surface is provided with a semicircular upper pressing groove to restrain and press the electric wire, and the upper pressing groove 430 is provided with sawtooth-shaped upper irregularities 431 to prevent the gripped electric wire from slipping.

[0069] Here, the upper part of the pressure gripper 400 is connected to the lower part of the rotating part 310 of the link part 300 via the fourth shaft 401, and is configured to move up and down by the rotation of the rotating part 310 to open and close the gap between it and the support gripper 110.

[0070] Furthermore, the pressure gripper 400 is equipped with a pressure spring 410, and is configured to impart pressure elasticity to the support gripper 110 through its elastic action.

[0071] To this end, a spring mounting pin 420 is provided on the upper surface, on which a pressure spring 410 is attached. The pressure spring 410 is configured such that one end is elastically attached to the rotating part 310 and the other end is elastically attached to the upper part of the pressure gripper 400, thereby providing the pressure elasticity to push the pressure gripper 400 towards the upper side of the support gripper 110.

[0072] Therefore, the pressing gripper 400 is configured to move upward while overcoming the force of the pressing spring 410 when the rotating part 310 rotates upward, thereby releasing the pressing force on the support gripper 110 and creating a gap between them, and to move downward when the rotating part 310 rotates downward, thereby pressing the upper part of the support gripper 110.

[0073] The automatic opening / closing plate 500 is configured in the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, to prevent the wire gripped between the support gripper 110 and the pressing gripper 400 from coming loose when the link portion 300 is operated.

[0074] For this purpose, the automatic opening and closing plate 500 is configured to be mounted on the outside of the pressing gripper 400 via the fourth shaft 401, with a spring support pin 520 protruding from the rear surface on the front side and a support projection 530 protruding from the rear end.

[0075] Here, as described above, the automatic opening and closing plate 500 formed on the fourth shaft 401 is configured to be elastic by an opening and closing spring 510, and the opening and closing spring 510 is mounted on the fourth shaft 401, with one end fixed to the pressing gripper 400 and the other end supported by the spring support pin 520, so that the front side has downward rotational elasticity around the fourth shaft 401.

[0076] Therefore, when the rotating part 310 of the link part 300 rotates downward, the automatic opening and closing plate 500 descends together with the pressing gripper 400, and the front side rotates downward due to the elasticity of the opening and closing spring 510, closing the space between the support gripper 110 and the pressing gripper 400.

[0077] Conversely, when the rotating part 310 rotates upward, it rises together with the pressing gripper 400, and when the support projection 530 at the rear end comes into contact with the opening / closing plate support pin 120 during the rising process, it is supported by the opening / closing plate support pin 120, and the front side rotates around the fourth axis 401 to completely open the space between the support gripper 110 and the pressing gripper 400, allowing the electric wire to be accommodated.

[0078] The opening and closing operation grips 600 and 600' are configured in the joint slide lever link type wire clip 1 having the function of an indirect live-line opening and closing operation grip guide according to the present invention to control the operation of the link portion 300 by the sliding operation of the wire clip body 100, and the operation of the pressing gripper 400 and the automatic opening and closing plate 500.

[0079] For this purpose, the opening and closing operation grips 600 and 600' are configured to form a pair on both sides. First, one opening and closing operation grip 600 is configured in the middle of the wire clip body 100, that is, close to the front side of the first guide hole 140, and the other opening and closing operation grip 600' is configured on the joint slide guide 200.

[0080] On the other hand, in the configuration of the opening and closing grips 600, 600' described above, by configuring the tip to form a ring portion 610, it is possible to configure it so that a variety of tools can be hung on it.

[0081] The operation of the articulated slide lever link type wire clip, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention and has the configuration described above, will be explained in detail below with reference to the attached drawings.

[0082] Referring to Figures 1 to 5, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, can easily grip and fix a wire in proportion to the amount of tension by sliding the joint with a small force, and in particular can prevent the gripped wire from moving and fix it stably.

[0083] For this purpose, when gripping an electric wire using the articulated slide lever link type electric wire clip 1 having the function of an indirect live-line opening / closing operation grip guide according to the present invention, the pressing gripper 400 is separated from the support gripper 110, and a space is secured between them, thereby enabling gripping in proportion to the magnitude of the tension of the electric wire 20.

[0084] This is made possible by the operation of the opening and closing grips 600 and 600', as shown in Figure 6. That is, with a standard indirect live-line work stick (not shown) gripping both opening and closing grips 600 and 600', the opening and closing grip 600 formed on the wire clip body 100 is pulled, using the opening and closing grip 600' formed on the joint slide guide 200 as a support point.

[0085] Therefore, the link section 300 is activated, and the connecting section 320 rotates upward around the second shaft 201. In this process, the rotating section 310 rotates clockwise, that is, upward, while compressing the restoring spring 311.

[0086] Furthermore, as described above, when the rotating part 310 rotates, the lower part of the rotating part 310, that is, the pressure gripper 400 and the automatic opening / closing plate 500 connected to the fourth shaft 401, move up and down while compressing the pressure spring 410 and the opening / closing spring 510. In this process, the space between the support gripper 110 and the pressure gripper 400 widens, securing space for accommodating the electric wire 20.

[0087] Here, the automatically opening and closing plate 500, which rises as described above, is supported by the opening and closing plate support pin 120 of the wire clip body 100 as the support projection 530 formed at its rear end comes into contact with the opening and closing plate support pin 120, and the front part rotates upward in an articulated manner with the fourth axis 401 as the pivot point, thereby completely opening the space between the support gripper 110 and the pressing gripper 400.

[0088] As described above, the electric wire 20 is housed between the open support gripper 110 and the pressing gripper 400, thereby releasing the tensile force on the opening / closing operation grip 600.

[0089] Specifically, referring to Figure 7, when the tensile force on the opening / closing grip 600 is released, the rotating part 310 of the link part 300 rotates counterclockwise downward due to the restorative elasticity of the restorative spring 311, thereby causing the pressing gripper 400 to descend, grip and fix the electric wire 20, and firmly grip and fix it due to the elasticity of the pressing spring 410.

[0090] Here, when the pressure gripper 400 grips the electric wire 20, the electric wire 20 is stably housed and fixed between the electric wire arrangement groove 111 of the support gripper 110 and the upper pressure groove 430 of the pressure gripper 400.

[0091] Furthermore, as described above, when the rotating part 310 rotates downward, the automatic opening / closing plate 500 also descends. When the automatic opening / closing plate 500 is released from the support force of the opening / closing plate support pin 120, the front part rotates downward around the fourth shaft 401 by the elastic action of the opening / closing spring 510. Thus, the space between the support gripper 110 and the pressure gripper 400, which are gripping the electric wire 20, is closed, preventing unintended detachment of the electric wire 20.

[0092] In other words, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening and closing operation grip guide according to the present invention, allows the wire to be gripped and fixed by the upward and downward movement of the pressing gripper 400 alone in proportion to the amount of tension, through the sliding operation of the wire clip body 100 and the articulation of the link portion 300, and can be operated stably with a particularly small force.

[0093] The following describes in detail, with reference to the attached drawings, a wire fixing method using an articulated slide lever link type wire clip that functions as an indirect live-line opening / closing operation grip guide according to the present invention, which has the configuration described above.

[0094] Figure 8 is a process diagram showing the entire process of a wire fixing method using an articulated slide lever link type wire clip that functions as an indirect live-line opening / closing operation grip guide according to the present invention.

[0095] Referring to Figures 1 to 7 and Figure 8, the wire fixing method using an articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention allows for easy indirect live-line work to grip and fix wires in proportion to the amount of tension when fixing wires using a tensioner during work processes such as adjusting the sag of wires, tightening wires, overhead wire installation, or replacing suspension insulators on power distribution lines, and consists of a work preparation step (S100), a tensioner installation step (S200), a wire fixing step (S300), a power distribution line main work step (S400), a wire separation step (S500), and a tensioner removal step (S600).

[0096] First, the work preparation process (S100) is:

[0097] In the wire fixing method using an articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention, an articulated slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide is prepared.

[0098] The articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide, is not limited to this purpose and can be prepared according to site conditions. For example, it can be prepared by being attached to a standard wire tensioner 10.

[0099] Here, the connection of the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide, to the tensioner 10 is not limited, and a variety of applications are possible, which in the present invention is made possible by the tensioner coupling part 210.

[0100] On the other hand, the tensioner 10 for which the joint slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide according to the present invention is applied is not limited, and any tensioner 10 such as those published in Korean Patent No. 10-1984829, No. 10-2161405, and No. 10-2447795, devised by the applicant of the present invention, is possible as long as it has a structure such as a hook 12 for installation on a crossarm of a utility pole etc. on one side of the tensioner body 11, and a connector 14 on the other side through which a belt 13 wrapped around the body 11 passes.

[0101] In this embodiment, first referring to Figure 9, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, is connected to the tensioner body 11 by connecting the wire clip 1 to the connector 14 via the tensioner coupling part 210, with the hook 12 connected to the tensioner body 11.

[0102] Furthermore, referring to Figure 10, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, can be connected to the tensioner body 11 via the tensioner coupling part 210 and a separate connector 15, etc., with the tensioner belt 13 connected to the hook 12 of the tensioner 10.

[0103] In other words, in the preparation step (S100), the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, is connected to the tensioner 10. Here, it can be applied in various ways depending on the working environment, regardless of the direction of the tensioner 10.

[0104] Furthermore, the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide, can be prepared as an integral part so that it can be used by attaching it to a rope (not shown) that can be attached to a regular crossarm or the like.

[0105] Subsequently, the tensioner installation process (S200) is carried out.

[0106] In the wire fixing method using an articulated slide lever link type wire clip having the function of an indirect live-line opening and closing operation grip guide according to the present invention, a tensioner 10 to which the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening and closing operation grip guide is attached is installed on a utility pole (not shown) for use in adjusting the slack of the wire, wire tensioning work, wire overheading work, suspension insulator replacement work, etc.

[0107] Therefore, the method of installing the tensioner 10, which is fitted with an articulated slide lever link type wire clip 1 that has the function of an indirect live-line opening and closing operation grip guide, on a utility pole is not limited and can be applied in various ways according to site conditions.

[0108] As an example, with the joint slide lever link type wire clip 1, which has the function of an indirect live-line opening and closing operation grip guide, prepared as in the above embodiment, connected to the tensioner 10, the tensioner 10 is installed on a utility pole (not shown) in order to perform tasks such as adjusting the slack of the wire, tightening the wire, overhead wire installation, or replacing the suspension insulator.

[0109] On the other hand, in the present invention, when attaching the tensioner 10 to the crossarm 21, regardless of the direction in which the wire clip 1 is connected to the tensioner 10 as described above, it is sufficient to install it on the utility pole using the hook 12 of the tensioner.

[0110] In this invention, the installation of the tensioner 10 on a utility pole is not limited to the above-mentioned method, and various installation methods are possible. Specifically, it can be installed by attaching it to the rope 22 attached to the crossarm 21 using the hook 12 as shown in Figure 11(a), or by attaching it to the dead end clamp 24 connected to the suspension insulator 23 as shown in Figure 11(b).

[0111] Here, as shown in Figure 12, the aforementioned wire-hanging operation can be performed safely at a distance using a live-line work stick 30 while approaching the vicinity of the power lines 20 on the utility pole using a live-line bucket to maintain a safe distance.

[0112] On the other hand, the indirect live-line work stick 30 to be applied in the present invention is not limited, and a variety of indirect live-line work sticks 30 can be applied. In embodiments of the present invention, it may be possible to apply the pliers stick described in Korean Patent No. 10-2021001, No. 10-1963537, No. 10-1963539, or the grip-all clamp stick described in Korean Patent No. 10-2028010, which were devised by the applicant of the present invention.

[0113] Subsequently, the wire fixing process (S300) is carried out.

[0114] In the wire fixing method using the articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention, the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide is used to grip and fix the wire 20 in order to perform wire slack adjustment, wire tensioning work, wire overheading work, or suspension insulator replacement work during indirect live-line work.

[0115] To achieve this, first, a gripper release process (S310) is performed to widen the gap between the support gripper 110 and the pressing gripper 400.

[0116] Here, the gripper release process (S310) is:

[0117] Referring to Figure 13 along with Figure 6, when the worker uses the indirect live-line work stick 30 to pull the opening / closing operation grip 600' formed on the joint slide guide 200 to one side, the wire clip body 100 slides backward using the guide member 230 and the first guide hole 140 of the joint slide guide 200 as guides.

[0118] Here, the moving wire clip body 100 moves backward together with the rotating part 310 of the link part 300 connected to the first shaft 101. As the gap between the first shaft 101 and the second shaft 201 narrows, the connecting part 320 connected via the third shaft 301 is pushed upward on the second shaft 201 as an axis, causing the rotating part 310 to rotate upward.

[0119] Furthermore, as described above, when the rotating part 310 rotates, the lower part of the rotating part 310, that is, the pressure gripper 400 and the automatic opening / closing plate 500 connected to the fourth shaft 401, rise while compressing the pressure spring 410 and the opening / closing spring 510. In this process, the space between the support gripper 110 and the pressure gripper 400 widens, securing space for accommodating the electric wire 20.

[0120] Here, as described above, the rising automatic opening and closing plate 500 is supported by the opening and closing plate support pin 120 of the wire clip body 100 when the support projection 530 formed at its rear end comes into contact with the opening and closing plate support pin 120, causing the front part to rotate upward around the fourth axis 401 as the pivot point. As a result, the space between the support gripper 110 and the pressing gripper 400 is completely opened.

[0121] Subsequently, a wire gripping process (S320) is performed in which the space for housing the electric wire 20 is secured between the support gripper 110 and the pressing gripper 400 as described above, and the electric wire 20 is gripped and fixed.

[0122] Here, the wire gripping process (S320) is,

[0123] The worker, while gripping the opening and closing operation grips 600 and 600' with the live-line work stick 30, and with the electric wire 20 housed between the support gripper 110 and the pressing gripper 400 at a distance, simply releases the tensile force on the opening and closing operation grip 600 formed on the electric wire clip body 100, as shown in Figure 14 and Figure 7.

[0124] Therefore, the rotating part 310 of the link part 300 rotates downward due to the restorative elasticity of the restorative spring 311. At this time, the pressure gripper 400 connected to the lower part of the rotating part 310 descends. The pressure gripper 400 presses the upper part of the electric wire 20 with the elasticity of the pressure spring 410, firmly gripping and fixing it between itself and the support gripper 110.

[0125] Alternatively, the electric wire 20 can be housed between the open support gripper 110 and the pressing gripper 400 as described above, thereby releasing the tensile force on the opening / closing operation grip 600.

[0126] In other words, when the tensile force on the opening / closing grip 600 is released, the rotating part 310 of the link part 300 rotates downward in a counterclockwise direction due to the restorative elasticity of the restorative spring 311. As a result, the pressure gripper 400 descends and grips and fixes the electric wire 20. At this time, the elasticity of the pressure spring 410 firmly grips and fixes the electric wire.

[0127] Here, when the pressure gripper 400 grips the electric wire 20, the electric wire 20 is stably housed and fixed between the electric wire arrangement groove 111 of the support gripper 110 and the upper pressing groove 430 of the pressure gripper 400. At this time, the gripped and fixed electric wire 20 is firmly held without slipping by the upper and lower irregularities 431 and 112 formed in the electric wire arrangement groove 111 and the upper pressing groove 430.

[0128] On the other hand, when the rotating part 310 rotates downward as described above, the automatic opening and closing plate 500 also descends. Here, when the automatic opening and closing plate 500 is released from the support force of the opening and closing plate support pin 120, the front part rotates downward around the fourth shaft 401 by the elastic action of the opening and closing spring 510. As a result, the space between the support gripper 110 and the pressing gripper 400, which are gripping the electric wire 20, is closed, completely preventing the unintended detachment of the electric wire 20.

[0129] Subsequently, the main work process for the power distribution line (S400) was as follows:

[0130] In the wire fixing method using the articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention, the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide installed on the tensioner 10 as described above is used to perform indirect live-line work such as adjusting the sag of the wire, wire tensioning work, wire overheading work, or suspension insulator replacement work.

[0131] Here, as mentioned above, when carrying out the main work on the power distribution lines, various methods can be used to suit the site conditions.

[0132] To this end, referring to Figure 15, when performing indirect live-line work such as adjusting the sag of the power lines, tightening the power lines, overhead power line installation, or replacing suspension insulators, it is possible to perform the work indirectly on a live line when the power lines 20 on both sides of a normal tension pole are connected by jumper wires 25 with respect to the pole.

[0133] Furthermore, referring to Figure 16, in indirect live-line work, when adjusting the sag of the power lines, tightening the power lines, overhead power line installation, or replacing suspension insulators, the jumper wire 25 connecting the power lines 20 on both sides of a normal tension pole is cut, and the power lines on both sides are bypassed with a bypass jumper cable 26. This can be performed as indirect live-line work.

[0134] On the other hand, in the embodiment of the power distribution line work garment of the present invention, power distribution line work was described as an example of wire sag adjustment, wire tensioning work, wire overhead installation work, or suspension insulator replacement work, but this is not limited to this, and it goes without saying that various tasks such as gripping the wire using the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening and closing operation grip guide, can be performed during indirect live-line work on power distribution lines.

[0135] Subsequently, the wire separation process (S500) is performed.

[0136] Referring to Figure 17, after performing the indirect live-line work as described above, the fixing force of the support gripper 110 and the pressing gripper 400 on the electric wire 20 is released, and the articulated slide lever link type electric wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide according to the present invention, is separated from the electric wire 20.

[0137] To this end, referring to Figure 13, similar to the gripper release step (S310) of the wire fixing step (S300), the open / close operation grip 600 of the wire clip body 100 is pulled to one side using the indirect live-line work stick 30, with the open / close operation grip 600' formed on the joint slide guide 200 as a support point, thereby raising the pressure gripper 400 and releasing the gripping force on the wire 20.

[0138] Here, as described above, when the pressure gripper 400 rises, the automatic opening and closing plate 500 also rises together, and its front part rotates upward, completely opening the space between the support gripper 110 and the pressure gripper 400, allowing the electric wire 20 to freely enter and exit.

[0139] Afterward, as described above, the opening / closing operation grip 600 is pulled to one side to completely open the space between the support gripper 110 and the pressing gripper 400, and the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening / closing operation grip guide, can be separated from the wire 20.

[0140] Subsequently, the wire tensioner removal process (S600) is carried out.

[0141] Referring to Figure 18, in the wire fixing method using the articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention, the tensioner 10 can be removed with the articulated slide lever link type wire clip 1 having the function of an indirect live-line opening / closing operation grip guide separated from the wire 20 as described above. Referring to Figure 12, while maintaining a safe distance using a live-line bucket and approaching the vicinity of the wire 20 on the utility pole, the removal work can be safely carried out from a distance using a live-line work stick 30.

[0142] Therefore, by using the wire fixing method with the articulated slide lever link type wire clip 1, which has the function of an indirect live-line opening and closing operation grip guide, as described above, it is possible to perform work in indirect live-line operations by gripping and fixing the wire in proportion to the magnitude of the tension.

[0143] As described above, the articulated slide lever link type wire clip having the function of an indirect live-line opening / closing operation grip guide according to the present invention, and the wire fixing method using the same, can be used in conjunction with a tensioner applied in the process of adjusting sag, tightening wires, overhead wire installation, or replacing suspension insulators. In particular, in the process of gripping and fixing the wire, a safe distance from the live wire can be ensured, and the work can be performed easily and quickly even at a distance using an indirect live-line work stick or the like, and the gripped and fixed wire can be stably fixed without detachment. [Industrial applicability]

[0144] The articulated slide lever link type wire clip and wire fixing method using the same, which have the function of an indirect live-line opening and closing operation grip guide according to the present invention, allow for easy release of the gripper and gripping of the wire during indirect live-line work using an indirect live-line work stick while ensuring a sufficient safety distance from the wire. This prevents safety accidents during long-distance indirect live-line work and enables convenient wire fixing work. The simplification of the structure and operation further improves durability, and the gripper can be released with little force, enabling convenient operation and quick and convenient wire fixing work. When gripping and fixing the wire, it has the effect of stably gripping and fixing the wire without any movement. [Explanation of Symbols]
