Abstract
Description
[Technical Field]
[0001] The present invention relates to an indirect live line tensioner and an indirect live line stringing method, and more particularly to an indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner that can automatically adjust the rotation direction, such as winding or unwinding a belt, by simply operating a rotary lever using an indirect live line stick without a separate rotation direction changing operation, and that prevents reverse rotation, and that allows for convenient indirect live line work such as installing and removing insulators and stringing electric wires using the tensioner, and an indirect live line stringing method using the same. [Background technology]
[0002] Generally, live-line work refers to work carried out on power lines while power is being transmitted without a power outage. Because live-line work poses a high risk of safety accidents, it is carried out in places where it is difficult to cut off power, such as power transmission and distribution facilities, and workers who perform live-line work must always wear insulating protective gear or protective equipment.
[0003] Live-line work on power lines can be divided into direct live-line work and indirect live-line work. Indirect live-line work is an indirect method of work using insulated tools such as hot sticks. While indirect live-line work is safe, it has the disadvantage of taking a long time to complete the work.
[0004] Direct live-line work is a method in which workers wear insulated gloves and work directly in contact with live electric wires inside an insulated bucket. While direct live-line work is simple and saves time, it has the disadvantage of being prone to electric shock and often resulting in loss of life. Live-line work includes inspecting, repairing, replacing, and cleaning electric line components such as support insulators, and either direct live-line work or indirect live-line work can be used appropriately depending on the type of work.
[0005] Meanwhile, wire tensioners are widely used in various live-line work. Such wire tensioners are tools used to tension or release wires to create a dip suitable for stringing and adjusting slack in live-line work, and are operated by adjusting the forward and reverse rotation of a drum around which a belt is wound.
[0006] An example of such a wire tensioner is disclosed in Korean Patent Registration No. 10-1179056. The wire tensioner disclosed in the publication includes a wire tensioner fixture having a hook, a wire winder including a drum connected to the underside of the wire tensioner fixture, a wire belt wound around the drum, a ratchet wheel disposed on one side of the wire winder and coaxially connected to the drum so as to rotate the drum in only one direction, a ratchet rotatably disposed on one side of the wire winder on which the ratchet wheel is disposed and one end of which engages with the ratchet wheel, a handle coaxially connected to the ratchet wheel for rotating the ratchet wheel and the drum, and a wire clamp connected to the free end of the wire belt to clamp the wire.
[0007] However, such conventional ratchet wheel type wire tensioners require the operator to push and pull the handle to wind the wire belt around the drum, which poses a fatal problem that makes them unusable for indirect live-line work using an insulating stick.
[0008] In order to solve the above-mentioned problems, the applicant of the present invention has proposed a ratchet wheel type wire tensioner 10 in Korean Patent No. 10-2161405, as shown in Figures 1 and 2, in which the forward or reverse rotation structure is achieved by adjusting the forward or reverse rotation of the ratchet wheel 12 to which the drum 11 is connected, and a pair of ratchet tensioners 13, 13' for the forward or reverse rotation of the ratchet wheel 12 are formed on both sides of the ratchet wheel 12, and the ratchet tensioners 13, 13' are connected to a direction change lever 15 connected via a link member 14, and depending on the direction change operation of the direction change lever 15, either one of the ratchet tensioners 13, 13' engages with the ratchet wheel 12, allowing the ratchet wheel 12 to rotate in the forward or reverse direction.
[0009] However, in the conventional wire tensioner, in order to adjust the rotation direction in the forward or reverse direction for winding or unwinding, it is necessary to operate a direction change lever to adjust the rotation direction in the forward or reverse direction, which is very inconvenient to operate and requires the operator to operate it in close proximity, which has the problem of exposing the operator to safety accidents.

[0056] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0057] Figure 3 is an oblique view of an automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live lines according to the present invention, Figure 4 is an oblique view showing the main parts of an automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live lines according to the present invention, Figure 5 is a cross-sectional plan view showing the main parts of an automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live lines according to the present invention, and Figure 6 is a cross-sectional front view showing the main parts of an automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live lines according to the present invention.
[0058] As shown in Figures 3 to 6, the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines according to the present invention comprises a body 100, a rotary actuation lever 200, a drum 300, a clutch unit 400, a drum shaft actuation plate 500, a pendulum 600, a drum shaft support plate 700, an automatic reversal pole 800, a pole reversal key 900, a drum shaft rotation lever 1000, a belt 1100, and a wire clip 1200.
[0059] First, the body 100 is configured to form the basis of the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines according to the present invention, and is configured to be U-shaped so that it is open on one side on a flat surface and has a space inside in which the belt 1100 described later can be wound.
[0060] In addition, a hook 101 is formed on one closed end of the body 100 so that a normal rope or the like can be hung on the cross arm of a power distribution line, and a belt fixing pin 102 is formed on the opposite open end.
[0061] Also, a hollow lever shaft receiving portion 110 is formed on one front side of the body 100 .
[0062] The rotary actuating lever 200 is configured to apply an actuating force for rotating the drum shaft 310 in the forward or reverse direction, as will be described later, in the configuration of the automatic direction-changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0063] For this purpose, the rotary actuating lever 200 is first composed of a rotary actuating shaft 210 that is horizontally mounted on the lever shaft mounting portion 110, and the tip of the rotary actuating shaft 210 is located inside the lever shaft mounting portion 110, and the rear end of the rotary actuating shaft 210 protrudes outside the lever shaft mounting portion 110 to form a rotary knob 211.
[0064] In addition, the rotation actuation lever 200 has a cam 220 at the tip of the rotation actuation shaft 210, which is eccentric to one side from the center.
[0065] In addition, the rotation actuation lever 200 has a rotation actuation member 230 formed around the rotation actuation shaft 210 on the rear side of the cam 220, and the rotation actuation member 230 is configured to be slidably coupled to the rotation actuation shaft 210.
[0066] A floating elongated hole 231 is formed on one side of the circumference of the rotational actuator 230 so as to form an angle of approximately 110° in the circumferential direction, and a locking projection 232 is provided on the other side.
[0067] The rotary actuation lever 200 is also provided with a buffer key 240 for applying a connecting force between the rotary actuation shaft 210 and the rotary actuation member 230. One side of the buffer key 240 is fixed to the rotary actuation shaft 210, and the other side is configured to be positioned inside the free-moving slot 231 of the rotary actuation member 230.
[0068] Therefore, when the rotary operating shaft 210 is rotated in the forward or reverse direction, the buffer key 240 rotates freely within the free-moving slot 231 for a certain period of time, and when it engages with one end of the free-moving slot 231, it rotates the rotary operating member 230 together. In this process, it is possible to prevent an impact overload on the drum shaft operating plate 500, which will be described later, due to sudden rotation.
[0069] In the configuration of the automatic direction-changing pendulum-type rotary drive ratchet tensioner 1 for indirect live lines according to the present invention, the drum 300 is configured to apply a rotational force substantially in the forward or reverse direction to wind or unwind the belt 1100 described below.
[0070] For this purpose, the drum 300 has a drum shaft 310 formed at the center of the inner surface of the body 100. The drum shaft 310 is axially installed to penetrate the body 100 from front to rear and protrudes forward.
[0071] The clutch unit 400 is configured to operate the rotation of the drum shaft 310 in the forward or reverse direction in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention, and is configured to be connected to the drum shaft 310 protruding from the front of the body 100 by passing through it.
[0072] Meanwhile, in the present invention, the clutch unit 400 is not limited to any particular type, and may be configured as a cam clutch in which a cam is formed between a normal inner ring and an outer ring, so that when the inner ring rotates in the forward direction, only the inner ring can rotate, and when the inner ring rotates in the reverse direction, both the inner ring and the outer ring can rotate simultaneously.
[0073] 7 to 11, the clutch unit 400 can be configured with a backstop ratchet ring 401. In the present invention, the backstop ratchet ring 401 includes an outer ring 410, an inner ring 420, a multi-angle bundle pole unit 430, and a rotation prevention lever 440.
[0074] First, the outer ring 410 is configured to output power to the outside in the configuration of the backstop ratchet ring 401, and is configured to form a circle with an inner ring mounting hole 411 in the center through which the inner ring 420 described later is mounted.
[0075] Here, in the present invention, the outer ring 410 has an outer ring sawtooth portion 412 formed on the inner peripheral surface of the inner ring mounting hole 411, and the outer ring sawtooth portion 412 is formed so that straight portions and inclined portions are formed continuously.
[0076] Meanwhile, in the present invention, as described above, the straight portion constituting the outer ring sawtooth portion 412 is configured to lock during power transmission, and the inclined portion is configured to guide slippage during idle rotation.
[0077] In the present invention, a number of stopping grooves 413 are formed at regular intervals on the outer periphery of the outer ring 410 so that a rotation preventing lever 440 (to be described later) can be locked or unlocked.
[0078] The inner ring 420 is configured to substantially transmit the main power in the configuration of the backstop ratchet ring 401, and is configured to transmit or release the main power to the outer ring 410 by interfering with or releasing the outer ring 410.
[0079] For this purpose, in the present invention, the inner ring 420 is configured to have a ring shape with a drum shaft mounting hole 421 through which the drum shaft 310 for transmitting rotational power is connected at the center, and is configured to be inserted into the inner ring mounting hole 411 of the outer ring 410.
[0080] Also, a number of bundle pole mounting grooves 422 are formed at regular intervals in the circumferential direction on the outer periphery of the inner ring 420 so that first, second and third multi-angle bundle poles 431, 432 and 433, which will be described later, can be mounted thereon.
[0081] Meanwhile, in the present invention, the outer ring 410 and the inner ring 420 are configured to be tightly coupled and to allow stable sliding operation when coupled to each other.
[0082] For this purpose, first, the outer ring sawtooth portion 412 of the outer ring 410 is configured to protrude a predetermined length into the inner ring mounting hole 411, and front and rear step portions 412a, 412b are formed in front and rear of the outer ring sawtooth portion 412.
[0083] First, a mounting protrusion 423 is protruded from the rear periphery of the inner ring 420, and is mounted on the rear step portion 412b of the outer ring 410 and guided by sliding, and a finishing plate support portion 424 is protruded from the front so as to extend from the drum shaft mounting hole 421.
[0084] First, the front of the inner ring 420 is configured to be finished with a finishing plate 425, and the periphery of the finishing plate 425 is attached to the front step portion 412a of the outer ring 410 and is fastened to the inner ring 420 with bolts to restrain the outer ring sawtooth portion 412, and a through hole 425a is provided in the center through which the finishing plate support portion 424 of the inner ring 420 passes.
[0085] The multi-angle bundle pole unit 430 acts as a medium for transmitting or releasing the power of the inner ring 420 to the outer ring 410 by interacting with the outer ring sawtooth portion 412 of the outer ring 410 in the configuration of the backstop ratchet ring 401. In the present invention, the multi-angle bundle pole unit 430 is composed of a plurality of sets of first, second and third multi-angle bundle poles 431, 432, 433.
[0086] To this end, the first, second and third multi-angle bundle poles 431, 432, 433 are elastically installed in the bundle pole mounting grooves 422 via springs S, and configured to protrude and retract from the outer periphery, and to mesh with the outer ring sawtooth portion 412 of the outer ring 410 to apply a rotational force in one direction.
[0087] Here, in the present invention, the first, second and third multi-angle bundle poles 431, 432, 433 are configured so that one group is made up of three sets, and each set may be radially arranged, i.e., composed of first, second and third meshing tools 431a, 432a, 433a, each set consisting of four pieces spaced at 90° intervals.
[0088] In the present invention, the first, second and third meshing tools 431a, 432a, 433a corresponding to each set are elastically mounted in the bundle pole mounting groove 422 via springs S, and are configured to have a protruding force, and the tips of the first, second and third meshing tools 431a, 432a, 433a are each configured with meshing tool sawtooth portions 431b, 432b, 433b having straight portions and inclined portions so as to mesh with the outer ring sawtooth portion 412 of the outer ring 410.
[0089] In particular, in the present invention, the first, second, and third meshing tools 431a, 432a, and 433a corresponding to each set of the first, second, and third multi-angle bundle poles 431, 432, and 433 are configured to intersect with each other when installed in the bundle pole installation grooves 422, i.e., so that the first meshing tool 431a of the first multi-angle bundle pole 431, the second meshing tool 432a of the second multi-angle bundle pole 432, and the third meshing tool 433a of the third multi-angle bundle pole 433 are continuously repeated in one rotational direction, so that the meshing tool sawtooth portions 431b, 432b, and 433b are configured to sequentially mesh with the outer ring sawtooth portion 412 at positions of different angles.
[0090] That is, in the present invention, the meshing tool sawtooth portion 431b, 432b, 433b of any one of the first, second, and third meshing tools 431a, 432a, 433a of the first, second, and third multi-angle bundle poles 431, 432, 433 meshes with the outer ring sawtooth portion 412 of the outer ring 410. As an example, when the straight portion of the meshing tool sawtooth portion 431b of the first meshing tool 431a comes into contact with and meshes with the straight portion of the outer ring sawtooth portion 412, the straight portion of the meshing tool sawtooth portion 432b of the second meshing tool 432a is located at the end of the inclined portion of the outer ring sawtooth portion 412 and does not mesh with it, and the straight portion of the meshing tool sawtooth portion 433b of the third meshing tool 433a is located in the middle of the inclined portion of the outer ring sawtooth portion 412.By dividing the meshing sections of the meshing tool sawtooth portions 431b, 432b, 433b within one pitch of the outer ring sawtooth portion 412, the gap between the sawtooths is minimized.
[0091] Meanwhile, in the embodiment of the present invention, the first, second and third multi-angle bundle poles 431, 432, 433 forming a plurality of sets have been described as three-piece sets, but this is not limited thereto, and the first, second and third multi-angle bundle poles 431, 432, 433 may be arranged in various ways at equal intervals.
[0092] For example, it may be configured with four multi-angle bundle poles, each of which has four interlocking tools, or it may be configured with three multi-angle bundle poles, each of which has eight interlocking tools. By adjusting the number of poles in this way, the precision of the backstop ratchet ring 401 can be adjusted depending on the application.
[0093] The anti-rotation lever 440 is configured to control the rotation or stop of the outer ring 410 in a backstop ratchet ring 401 configuration.
[0094] For this purpose, the rotation prevention lever 440 is pivotally mounted on the body 100 and resilient via a spring, so that it can be inserted into or removed from the stopping groove 413 of the outer ring 410 by rotation. That is, when inserted, it blocks the rotation of the outer ring 410, and when removed, it allows the rotation of the outer ring 410.
[0095] The drum shaft actuating plate 500 is configured to transmit a rotational force to the drum shaft 310 in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0096] For this purpose, the drum shaft actuating plate 500 is in the form of a circular plate having a predetermined thickness, and is coupled to the periphery of the drum shaft 310 on the front side of the clutch part 400, and has a triangular sawtooth part 510 protruding from the periphery of the middle part.
[0097] The pendulum 600 is configured to control the reciprocating rotation of an automatic reversing pole 800 (described later) by pendulum motion in the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0098] For this purpose, the pendulum 600 is configured to pass through the rear side of the drum shaft operating plate 500 without rotational interference, and is formed with a horizontal slot 610 that protrudes to one side and accommodates the cam 220 of the rotation operating lever 200. When the cam 220 rotates, it interferes with the horizontal slot 610 and performs a pendulum motion by rotating back and forth around the drum shaft 310.
[0099] The pendulum 600 has an automatic reversal pole mounting groove 620 formed on the front surface between the rotary operating shaft 210 and the drum shaft operating plate 500, in which an automatic reversal pole 800 (described later) is mounted.
[0100] The drum shaft support plate 700 is configured to mount a pole reversal key 900, which will be described later, in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0101] For this purpose, the drum shaft support plate 700 is configured to pass through the front side of the drum shaft operating plate 500 without rotational interference, is connected to the pendulum 600 to restrain the drum shaft operating plate 500, and protrudes toward the rotary operating shaft 210.
[0102] In the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines according to the present invention, the automatic reversal pole 800 is configured to interfere with the drum shaft operating plate 500, thereby automatically rotating the drum shaft operating plate 500 in the forward or reverse direction.
[0103] For this purpose, the automatic reversal pole 800 is configured to be coupled to the automatic reversal pole mounting groove 620 of the pendulum 600 via the drum shaft 310, so that the drum shaft operating plate 500 is configured to rotate back and forth.
[0104] Meanwhile, in the present invention, as shown in FIG. 12, the automatic reversing pole 800 has first and second triangular engaging protrusions 810 and 810′ symmetrically protruding from the tip, i.e., on the drum shaft operating plate 500 side, which selectively engage with the sawtooth portion 510 of the drum shaft operating plate 500.
[0105] In addition, first locking grooves 821, 821' and second locking grooves 822, 822' are formed around the automatic reversing pole 800, forming a curved shape. The first locking grooves 821, 821' and second locking grooves 822, 822' are formed symmetrically to each other so that the first locking groove 821 and the second locking groove 822 on either side are located on the first and second locking protrusions 810, 810' sides, respectively.
[0106] In addition, a reversal key mounting groove 830 is formed in the center of the automatic reversal pole 800, into which a pole reversal key 900 (described later) is mounted. The reversal key mounting groove 830 is configured to have a tapered groove shape that expands from the drum shaft operating plate 500 side toward the rotary operating shaft 210 side.
[0107] Meanwhile, the automatic reversing pole 800 is configured to be elastically mounted via first and second reversing pole spring balls 840 and 840', and the first and second reversing pole spring balls 840 and 840' are connected to the pendulum 600 and configured to have elasticity to protrude toward the automatic reversing pole 800.
[0108] In the present invention, the first and second reverse pole spring balls 840 and 840' are configured to interfere with the first locking grooves 821 and 821' and the second locking grooves 822 and 822'. Here, the first reverse pole spring ball 840 is configured to interfere with one of the first locking grooves 821 and 821' at an intersecting position, and the second reverse pole spring ball 840' is configured to interfere with one of the second locking grooves 822 and 822' at an intersecting position.
[0109] For example, when the drum shaft operating plate 500 rotates in a forward direction, i.e., clockwise, the first reverse pole spring ball 840 on one side is engaged with the first locking groove 821′ located on one side, and the first reverse pole spring ball 840′ on the other side is engaged with the second locking groove 822 located on the other side. Conversely, when the drum shaft operating plate 500 rotates in a counterclockwise direction, it is preferable that the first reverse pole spring ball 840 on one side is engaged with the first locking groove 821 located on one side, and the first reverse pole spring ball 840′ on the other side is engaged with the second locking groove 822′ located on the other side.
[0110] The pole reversal key 900 is configured to apply a reciprocating rotation force to the automatic reversal pole 800 in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0111] For this purpose, the pole reversal key 900 is received in the reversal key mounting groove 830 of the automatic reversal pole 800, and is coupled to the drum shaft support plate 700 via the same drum shaft 310 as the automatic reversal pole 800, and protrudes to one side, i.e., the side of the rotary operating shaft 210. Therefore, when the rotary operating shaft 210 rotates, the locking protrusion 232 of the rotary operating member 230 interferes with the rotation of the rotary operating shaft 210, causing it to rotate back and forth.
[0112] Here, the pole reversal key 900 is configured to have a horizontal force that always maintains the horizontal state, and for this purpose, both sides are configured to be resiliently supported by first and second reversal key spring balls 910, 910' formed on the drum shaft support plate 700 with respect to the drum shaft 310.
[0113] The drum shaft rotating lever 1000 is configured to transmit the rotational force of the drum shaft operating plate 500 to the drum shaft 310 in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention.
[0114] For this purpose, the drum shaft rotating lever 1000 is configured to be coupled to the front side of the drum shaft 310 and the drum shaft operating plate 500, and is configured to rotate together with the drum shaft 310 and the drum shaft operating plate 500.
[0115] In the configuration of the automatic direction-changing pendulum-type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention, the belt 1100 is wound around the drum shaft 310 and is configured to be wound around or unwound from the drum 300 as the drum shaft 310 rotates in the forward or reverse direction.
[0116] For this purpose, one side of the belt 1100 is fixed to and wound around the drum 300 inside the body 100 , and the other side is fixed to a belt fixing pin 102 formed on the body 100 .
[0117] The electric wire clip 1200 is configured to be attached to the belt 1100 in the configuration of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wires according to the present invention, and can grip and fix the electric wire during normal electric wire installation work.
[0118] Here, in the present invention, the electric wire clip 1200 is not a new one, and a clamp capable of holding a normal electric wire can be applied.
[0119] In particular, in the present invention, the electric wire clip 1200 may be applied to the electric wire clip applied to the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live wiring, which can grip electric wires in indirect live wiring work, as invented by the applicant of the present invention and disclosed in Korean Patent Registration No. 10-2161405.
[0120] The operation of the automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live wires according to the present invention having the above-mentioned configuration will now be described in detail with reference to the accompanying drawings.
[0121] As shown in Figures 3 to 12, the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines according to the present invention applies a rotational force in the forward or reverse direction to the drum shaft 310 to wind or unwind the belt 1100 around the drum 300 to adjust the tension of the electric wire. In this case, the drum shaft 310 can be rotated in the forward or reverse direction simply by adjusting the rotational direction of the rotary operating shaft 210 during indirect live line work while maintaining a safe distance from the distribution line using a live line work stick equipped with an electric mechanism, without operating a separate direction changing lever.
[0122] Therefore, in order to wind up the belt 1100 and apply tension to the automatic direction-changing pendulum type rotary drive ratchet tensioner 1 for indirect live wires according to the present invention, the drum shaft 310 is rotated clockwise, i.e., in the positive direction. The operating state will be described below.
[0123] To do this, the rotation actuation lever 200 is rotated counterclockwise as shown in Figure 13. Here, the rotation prevention lever 440 is inserted into one of the stopping grooves 413 of the outer ring 410 to prevent the outer ring 410 from rotating.
[0124] Therefore, when the rotation actuation lever 200 is operated to rotate the rotation actuation shaft 210 counterclockwise, the cam 220 rotates within the horizontal slot 610 of the pendulum 600. In this process, the pendulum 600 performs a pendulum motion, reciprocating around the drum shaft 310.
[0125] At the same time, the locking protrusion 232 of the rotation actuator 230 formed on the rotation actuation shaft 210 rotates the pole reversal key 900 toward the first locking grooves 821, 821'. Therefore, the pole reversal key 900 pushes the automatic reversal pole 800 toward the first locking grooves 821, 821', causing it to rotate clockwise around the drum shaft 310. Here, the first locking protrusion 810 on the first locking groove 821 side engages with the sawtooth portion 510 of the drum shaft actuation plate 500.
[0126] Therefore, when the rotary operating shaft 210 is continuously rotated, the pendulum 600 reciprocates due to the operation of the cam 220 and the horizontal slot 610. During this process, the pole reversal key 900, which is rotated in the rotational direction by interference with the locking protrusion 232 of the rotary operating member 230, supports the first locking grooves 821, 821' of the automatic reversal pole 800 and pushes and rotates the drum shaft operating plate 500 which engages with the automatic reversal pole 800 that rotates reciprocally together. Here, as the drum shaft operating plate 500 rotates in the forward direction, the drum shaft 310 rotates, causing the belt 1100 to be wound around the drum 300.
[0127] Meanwhile, the present invention is configured to prevent the drum shaft 310 from rotating in the reverse direction when the drum shaft 310 rotates due to tension, as described above, and this is made possible by the clutch unit 400.
[0128] Here, in the present invention, the clutch unit 400 is composed of a backstop ratchet ring 401, and the reverse rotation is prevented by the backstop ratchet ring 401. The operation relationship will be explained as follows.
[0129] Referring to Figure 14, when the inner ring 420 connected to the drum shaft 310 rotates in the forward direction, the inclined portions of the meshing tool sawtooth portions 431b, 432b, 433b of the first, second, and third meshing tools 431a, 432a, 433a constituting the first, second, and third multi-angle bundle poles 431, 432, 433 respectively pass along the inclined portion of the outer ring sawtooth portion 412 of the outer ring 410.
[0130] That is, springs S are elastically attached to the first, second and third meshing tools 431a, 432a and 433a of the inner ring 420, respectively, so that the meshing tool sawtooth portions 431b, 432b and 433b passing along the outer ring sawtooth portion 412 are pushed backward by the compressive force of the springs S, and the inclined portions of the outer ring sawtooth portion 412 and the inclined portions of the meshing tool sawtooth portions 431b, 432b and 433b slide against each other and pass over each other.
[0131] Meanwhile, when the forward driving is stopped, a rotational force that rotates the inner ring 420 in the reverse direction may be applied due to the tension of the belt 1100. Here, in the backstop ratchet ring 401, the meshing tool sawtooth portions 431b, 432b, and 433b formed on the first, second, and third meshing tools 431a, 432a, and 433a of any one of the first, second, and third multi-angle bundle poles 431, 432, and 433 mesh with the outer ring sawtooth portion 412, thereby preventing the reverse rotation and stably winding up the belt 1100 to apply tension.
[0132] Conversely, to release the tension of the belt 1100 and unwind the belt 1100 from the drum 300, the drum shaft 310 is rotated counterclockwise, i.e., in the reverse direction. The operation will be described in detail as follows.
[0133] 15, when the rotation actuation lever 200 is operated to rotate the rotation actuation shaft 210 clockwise, the cam 220 rotates within the horizontal slot 610 of the pendulum 600. In this process, the pendulum 600 performs a pendulum motion, rotating back and forth around the drum shaft 310.
[0134] In this case, the locking protrusion 232 of the rotation actuator 230 formed on the rotation actuation shaft 210 pushes the pole reversal key 900 toward the second locking grooves 822, 822'. Therefore, the pole reversal key 900 pushes the automatic reversal pole 800 toward the second locking grooves 822, 822', causing it to rotate counterclockwise around the drum shaft 310. Here, the second locking protrusion 810' on the second locking groove 822 side of the automatic reversal pole 800 engages with the sawtooth portion 510 of the drum shaft actuation plate 500.
[0135] Therefore, when the rotary operating shaft 210 is continuously rotated, the pendulum 600 reciprocates due to the operation of the cam 220 and the horizontal slot 610. During this process, the pole reversal key 900, which is rotated in the rotational direction by interference with the locking protrusion 232 of the rotary operating member 230, supports the second locking groove 822' side of the automatic reversal pole 800 and pushes and rotates the drum shaft operating plate 500, which engages with the automatic reversal pole 800 that rotates reciprocally together. Here, as the drum shaft operating plate 500 rotates in the reverse direction, the drum shaft 310 rotates, unwinding the belt 1100 from the drum 300.
[0136] Meanwhile, in the present invention, when the outer ring 410 is driven by the reverse operation of the inner ring 420 as described above, the backlash (play phenomenon) of the inner ring 420 can be reduced to nearly zero, thereby preventing shock during power transmission.
[0137] The above-mentioned operation is performed by the multi-angle bundle pole unit 430 for transmitting the rotational power of the inner ring 420 to the outer ring 410.
[0138] That is, as shown in FIG. 16, in the present invention, the meshing tool sawtooth portions 431b, 432b, 433b of any one of the first, second, and third meshing tools 431a, 432a, 433a of the first, second, and third multi-angle bundle poles 431, 432, 433 sequentially mesh with the outer ring sawtooth portion 412 of the outer ring 410.
[0139] As an example, when the straight portion of the meshing tool sawtooth portion 431b of the first meshing tool 431a comes into contact with and meshes with the straight portion of the outer ring sawtooth portion 412, the straight portion of the meshing tool sawtooth portion 432b of the second meshing tool 432a is located at the end of the inclined portion of the outer ring sawtooth portion 412 and does not mesh with it, and the straight portion of the meshing tool sawtooth portion 433b of the third meshing tool 433a is located in the middle of the inclined portion of the outer ring sawtooth portion 412.As a result, when the inner ring 420 rotates, the first, second and third meshing tools 431a, 432a, 433a sequentially apply meshing force to the outer ring sawtooth portion 412, so that the multi-angle bundle pole unit 430 is always in a state of sequentially meshing with the outer ring sawtooth portion 412.
[0140] That is, in the backstop ratchet ring 401, the meshing sections of the meshing tool sawtooth portions 431b, 432b, and 433b are divided within one pitch of the outer ring sawtooth portion 412. Therefore, meshing force can be obtained despite minute rotation at positions of different angles, and therefore, when power is transmitted in the opposite direction, precise power transmission is possible without backlash.
[0141] Meanwhile, in the automatic direction changing pendulum type rotary drive ratchet tensioner 1 for indirect live wires according to the present invention, as shown in Fig. 17, when the belt 1100 is to be fully wound or unwound before or after use or during preparation and tidying up for work, the drum shaft 310 can be easily rotated manually without operating the rotation actuation lever 200. In other words, with the rotation preventing lever 440 separated from the stopping groove 413 of the outer ring 410, the belt can be freely wound or unwound by manually adjusting the rotation of the drum shaft rotation lever 1000 connected to the drum shaft 310.
[0142] Hereinafter, the indirect live line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention having the above-mentioned configuration will be described in detail with reference to the accompanying drawings.
[0143] As shown in Figures 3 to 17, the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention can perform dip adjustment, wire tensioning work, suspension insulator replacement work, electric wire removal work, etc.
[0144] Meanwhile, the live-line work stick to be applied when carrying out the indirect live-line electric wire stringing method using the indirect live-line automatic direction-changing pendulum-type rotary drive ratchet tensioner according to the present invention is not limited and can be configured in a variety of ways, and in addition to ordinary live-line work sticks, the pliers sticks invented by the applicant of the present invention in Korean Patent Registration Nos. 10-2021001, 10-1963537 and 10-1963539 and the rotary grip all clamp stick in Korean Patent Registration No. 10-2028010 can be applied.
[0145] Example 1 As shown in Figs. 18 to 23, a dip adjustment state in an indirect live line stringing method using an indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention will be described.
[0146] When sagging or overtension occurs in the electric wires 30 already installed on both sides of the utility poles using the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines, proper dip adjustment is required, and this is achieved by carrying out a wire tensioner installation process, a wire fixing process, a dip adjustment process, an electric wire installation process, and a wire tensioner removal process. To this end, as shown in Figure 18, workers prepare the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines and the live line work stick S when approaching the vicinity of the electric wires 30 on the utility poles while maintaining a safe distance using a live line bucket.
[0147] Here, the wire tensioner installation process is as follows:
[0148] When adjusting the dip in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner 1 is installed on the rope 21 or dead end clamp 31 installed on the cross arm 20 of the utility pole.
[0149] For this purpose, the wire tensioner 1 may be installed by using a hook 101 to hang it on a rope 21 as shown in (a) or by hanging it on a dead-end clamp 21 as shown in (b), as shown in Figure 19. Such hanging work can be carried out over a long distance using a live-line work stick S.
[0150] Then, the wire fixing process is
[0151] When adjusting the dip in the indirect live line electric wire stringing method using the automatic direction changing pendulum type rotary drive ratchet tensioner for indirect live lines according to the present invention, as shown in Figure 20, the automatic direction changing pendulum type rotary drive ratchet tensioner for indirect live lines 1 clamps and fixes the already installed electric wire 30 with an electric wire clip 1200.
[0152] Then, the dip adjustment process is
[0153] In adjusting the dip in the indirect live line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention, the proper dip is adjusted by adjusting the tension of the wire 30, which is essentially equivalent to this operation, as shown in Figure 21. This can be performed by rotating the rotation operating lever 200 of the wire tensioner 1 in the forward or reverse direction to cause the pendulum 600 to perform a rotary pendulum motion, thereby rotating the automatic reversal pole 800, and rotating the drum shaft 310 connected to the drum shaft operating plate 500 in the forward or reverse direction to wind or unwind the belt 1100 around the drum 300, thereby pulling or loosening the wire 30, thereby adjusting the tension.
[0154] Here, in order to adjust the tension of the electric wire 30, the outer ring 410 is stopped or rotated by attaching or detaching the rotation preventing lever 440.
[0155] Here, in order to wind the belt 1100 around the drum 300 and apply tension to it, the rotation prevention lever 440 is inserted into the stopping groove 413 of the outer ring 410 and attached.
[0156] After that, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated counterclockwise using a live-line work stick, causing the drum shaft 310 to rotate clockwise and pull the belt 1100, thereby applying tension to the electric wire 30.
[0157] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the operation of the pole reversal key 900 and the automatic reversal pole 800, which are linked to the pendulum movement of the pendulum 600, to rotate the drum shaft actuation plate 500 and wind the belt 1100, as shown in Figures 13 and 14. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0158] To release the tension, the rotary actuation lever 200 is rotated clockwise using a live-line work stick while maintaining a safe distance from the wire, causing the drum shaft 310 to rotate counterclockwise and unwinding the belt 1100, thereby releasing the tension on the wire 30.
[0159] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the operation of the pole reversal key 900 and the automatic reversal pole 800, which are linked to the pendulum movement of the pendulum 600, to rotate the drum shaft actuation plate 500 and release the belt 1100, as shown in Figures 15 and 16. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0160] That is, in the dip adjusting process, the drum shaft 310 is rotated in the forward or reverse direction by adjusting the rotation actuation lever 200 in the forward or reverse direction as described above, thereby winding or unwinding the belt 1100 around the drum 300, thereby adjusting the tension of the wire 30 and adjusting the dip.
[0161] After that, the electric wire installation process is
[0162] When adjusting the dip in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the electric wire 30 is fixed in a state in which the dip of the electric wire 30 has been adjusted, as described above.
[0163] For this purpose, as shown in FIG. 22, the electric wire 30 is separated from the dead end clamp 31 with the dip adjusted, and the separated electric wire 30 is adjusted to the appropriate position with the dip adjusted, and then fixed to the dead end clamp 31 with the dip adjusted, thereby installing the electric wire 30.
[0164] After that, the wire tensioner removal process is as follows:
[0165] When adjusting the dip in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the installed indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner 1 is removed.
[0166] For this purpose, the wire tensioner installation process and the wire fixing process are carried out in reverse order, as shown in Fig. 23. First, the live-line work stick S is used to release the connection state of the wire clip 1200 in the reverse order of connection of the wire 30, and then the hook 101 is separated from the rope 21 in the reverse order of installation, thereby allowing the indirect live-line automatic direction-changing pendulum-type rotary drive ratchet wire tensioner 1 to be removed.
[0167] As described above, in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the worker can easily perform the dip adjustment work of the electric wire 30 while maintaining a safe distance from the electric wire 30 through the series of steps described above.
[0168] Example 2 24 to 29, the state of the electric wire tensioning work for installing an electric wire between electric poles using the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention will be described.
[0169] This involves using an indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 to remove the electric wires already installed on both sides of the utility poles and either replacing them with new electric wires, or laying new electric wires and installing them on the newly installed utility poles, and this is done by carrying out a wire extension process, a wire tensioner installation process, an electric wire fixing process, an electric wire installation process, and a removal process.
[0170] Here, in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, for the wire stringing work, the worker approaches the top of the utility pole while maintaining a safe distance using a live line bucket, as shown in Figure 24, and at this time, the wire tensioner 1 of the present invention and the live line work stick S are prepared.
[0171] Here, the wire drawing process is as follows:
[0172] When carrying out electric wire stringing work in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the electric wire 30 to be installed on the electric pole is pulled up onto the pole, i.e., to the installation position.
[0173] The wire-drawing process is not a new one in the present invention, and can be performed by a conventional method. For example, as shown in Fig. 25, the wire 30 can be pulled up by pulling a wire-drawing rope 40 manually or by a winch over a wire-drawing roller (not shown) installed on the cross arm 20.
[0174] After that, the wire tensioner installation process is as follows:
[0175] When carrying out electric wire tensioning work in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner 1 is installed on the cross arm 20 of the electric pole, or a dead end clamp 31 and a suspension insulator 32 are first installed on the cross arm 20, and then the tensioner 1 is installed on the installed dead end clamp 31.
[0176] For this reason, the wire tensioner 1 can be installed by hanging the hook 101 on the dead-end clamp 21, as shown in Fig. 26. Such hanging work can be performed over a long distance using a live-wire work stick S.
[0177] Then, the wire fixing process is
[0178] When carrying out wire tensioning work in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, as shown in Figure 27, the extended electric wire 30 is clamped and fixed by the wire clip 1200 of the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1.
[0179] After that, the electric wire installation process is
[0180] In carrying out the indirect live line stringing work using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention, as shown in Figure 28, a connecting work is carried out to connect the wire 30 to the cross arm 20 of the utility pole, which is essentially the same work as this work. Here, the rotation actuation lever 200 of the wire tensioner 1 is rotated forward or backward to cause the pendulum 600 to perform a rotary pendulum motion. Therefore, the automatic reversal pole 800 is rotated and the drum shaft 310 connected to the drum shaft operating plate 500 is rotated forward or backward to wind or unwind the belt 1100 around the drum 300, thereby pulling or loosening the wire 30 and adjusting the tension.
[0181] Here, in order to adjust the tension of the electric wire 30, the outer ring 410 is stopped or rotated by attaching or detaching the rotation preventing lever 440 to adjust the tension.
[0182] Here, in order to wind the belt 1100 around the drum 300 and apply tension to it, the rotation prevention lever 440 is inserted into the stopping groove 413 of the outer ring 410 and attached.
[0183] Then, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated counterclockwise using a live-line work stick, causing the drum shaft 310 to rotate clockwise and pull the belt 1100, applying tension to the electric wire 30.
[0184] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 13 and 14, thereby rotating the drum shaft actuation plate 500 and winding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0185] To release the tension, the rotary actuation lever 200 is rotated clockwise using a live-line work stick while maintaining a safe distance from the wire. As a result, the drum shaft 310 rotates counterclockwise, unwinding the belt 1100 and releasing the tension on the wire 30.
[0186] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 15 and 16, thereby rotating the drum shaft actuation plate 500 and unwinding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0187] That is, in the wire installation process, the tension of the wire 30 is adjusted by rotating the drum shaft 310 in the forward or reverse direction by adjusting the rotation actuation lever 200 in the forward or reverse direction as described above, thereby winding or unwinding the belt 1100.
[0188] Therefore, by the above operation, the tension can be adjusted during the installation work of the electric wire 30, thereby adjusting the distance between the electric wire 30 and the cross arm 20. Preferably, the end side of the electric wire 30 is in a loose state, so that the electric wire 30 can be easily installed in the dead-end clamp 31.
[0189] After that, the wire tensioner removal process is as follows:
[0190] When carrying out wire tensioning work in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the installed indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 is removed.
[0191] For this purpose, the wire tensioner installation process and wire fixing process are carried out in reverse order, as shown in Figure 29. First, the live-line work stick S is used to release the connection state of the wire clip 1200 with the wire 30 in the reverse order of connection, and then the hook 101 is separated from the rope 21 in the reverse order of installation, thereby allowing the indirect live-line automatic direction-changing pendulum-type rotary drive ratchet wire tensioner 1 to be removed.
[0192] Meanwhile, when performing the electric wire stringing work in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention, it goes without saying that when performing the work on both sides of the electric pole, the above steps are performed respectively.
[0193] As described above, in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the series of steps described above allows the worker to easily perform the electric wire stringing work while maintaining a safe distance from the electric wire 30.
[0194] Example 3 As shown in Figs. 30 to 36, the state of suspension insulator replacement work in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention will be described.
[0195] This involves using an indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 to remove the suspension insulator 32 already installed on one utility pole and replace it with a new suspension insulator 32', and is done by carrying out a wire tensioner installation process, a wire fixing process, a wire pulling process, a suspension insulator replacement process, a wire unraveling process, and a wire tensioner removal process.The replacement suspension insulator 32 can be one made up of multiple insulator strings connected together, as shown in Figure 31(a), or it can be a polymer suspension insulator with an integrated insulator string, as shown in (b).
[0196] In the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention, to replace the suspension insulator, the worker approaches the top of the utility pole while maintaining a safe distance using a live line bucket, as shown in Figure 30. At this time, the wire tensioner 1 according to the present invention and the live line work stick S are prepared.
[0197] Here, the wire tensioner installation process is as follows:
[0198] When performing suspension insulator replacement work in the indirect live line overhead line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner 1 is installed on a rope 21 attached to an arm 20 of a utility pole.
[0199] For this purpose, the wire tensioner 1 is installed by hooking the hook 101 onto the rope 21, as shown in Figure 31. Such hooking work can be performed indirectly over a long distance using a stick S for live-line work.
[0200] Then, the wire fixing process is
[0201] When replacing a suspension insulator in an indirect live line electric wire installation method using the automatic direction changing pendulum type rotary drive ratchet tensioner for indirect live lines according to the present invention, the already installed electric wire 30 is fixed by being clamped by the electric wire clip 1200 of the automatic direction changing pendulum type rotary drive ratchet tensioner 1 for indirect live lines, as shown in Figure 32.
[0202] Then, the wire pulling process is
[0203] When replacing a suspension insulator in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, as shown in Figure 33, the already installed suspension insulator 32 is separated and the tension of the wire 30 is adjusted to install a new suspension insulator 32'.
[0204] To this end, with the rotation prevention lever 440 inserted and installed in the stopping groove 413 of the outer ring 410, the rotation operating lever 200 of the wire tensioner 1 is rotated to rotate the pendulum 600 and cause it to perform pendulum motion, thereby rotating the automatic reversal pole 800 and rotating the drum shaft 310 connected to the drum shaft operating plate 500, thereby pulling the electric wire 30 and applying tension to it, thereby tightening the wire.
[0205] Then, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated counterclockwise using the live-line work stick, which rotates the drum shaft 310 clockwise and pulls the belt 1100, applying tension to the electric wire 30. At this point, the electric wire 30 becomes loose inside the point fixed by the electric wire clip 1200, i.e., the connection portion with the dead-end clamp 31.
[0206] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 13 and 14, thereby rotating the drum shaft actuation plate 500 and winding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0207] That is, in the wire tensioning process, as described above, the drum shaft 310 is rotated clockwise by adjusting the counterclockwise rotation of the rotation actuation lever 200, thereby winding the belt 1100 and pulling the wire 30 to apply tension.
[0208] After that, the suspension insulator replacement process is as follows:
[0209] When replacing a suspension insulator in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the already installed suspension insulator 32 is removed and a new suspension insulator 32' is installed, as shown in Figure 34.
[0210] For this purpose, when separating the electric wire 30 from the suspension insulator 32, first, the dead end clamp 31 of the electric wire 30 is separated from the suspension insulator 32, and then the suspension insulator 32 is separated from the cross arm 20.
[0211] Here, as described above, when separating the suspension insulator 32, if the suspension insulator 32 is composed of multiple insulator strings, only the insulator string to be replaced is separated, and if the suspension insulator 32 is a polymer suspension insulator with an integrated insulator string, the polymer suspension insulator is separated from the dead end clamp 31 and the cross arm 20.
[0212] When installing a new suspension insulator 32', the suspension insulator 32 is installed on the cross arm 20 in the reverse order of the separation of the suspension insulator 32.
[0213] Then, when connecting the separated electric wire 30 to a new suspension insulator 32', the dead end clamp 31 is used to connect the electric wire 30 to the new suspension insulator 32'.
[0214] Here, in the present invention, the methods for separating and installing the dead end clamp 31 and the suspension insulator 32 are not limited as described above, and may be variously applied according to the usual distribution line construction method.
[0215] After that, the wire unwinding process is
[0216] When replacing a suspension insulator in the indirect live line overhead line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner according to the present invention, the electric wire 30 tensioned in the electric wire tensioning process is released as shown in FIG. 35.
[0217] To this end, the rotary actuation lever 200 of the wire tensioner 1 is rotated to cause the pendulum 600 to perform a rotary pendulum motion, which in turn rotates the automatic reversal pole 800 and rotates the drum shaft 310 connected to the drum shaft actuation plate 500, thereby loosening the wire 30 and releasing the tension by unwinding the belt 1100 from the drum 300.
[0218] After that, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated clockwise using a live-line work stick, which rotates the drum shaft 310 counterclockwise, unwinding the belt 1100 and releasing the tension on the electric wire 30.
[0219] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 15 and 16, thereby rotating the drum shaft actuation plate 500 and unwinding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0220] That is, in the wire unwinding process, as described above, the clockwise rotation of the rotation actuation lever 200 is adjusted to rotate the drum shaft 310 counterclockwise, unwinding the belt 1100 and releasing the tension on the wire 30.
[0221] After that, the wire tensioner removal process is as follows:
[0222] When carrying out suspension insulator replacement work in the indirect live line overhead line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner of the present invention, the installed indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner 1 is removed.
[0223] For this purpose, the wire tensioner installation process and the wire fixing process are carried out in reverse order, as shown in Figure 36. First, the live-line work stick S is used to release the connection state of the wire clip 1200 in the reverse order of connection of the wire 30, and then the hook 101 is separated from the rope 21 in the reverse order of installation, thereby allowing the indirect live-line automatic direction-changing pendulum-type rotary drive ratchet wire tensioner 1 to be removed.
[0224] As described above, in the indirect live line stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet tensioner according to the present invention, the worker can easily carry out the suspension insulator replacement work while maintaining a safe distance from the electric wire 30 through the series of steps described above.
[0225] Example 4 As shown in Figs. 37 to 43, the state of removing an already installed electric wire by the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention will be described.
[0226] This is for removing an electric wire 30 already installed on a utility pole using an indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1, and is done by carrying out a wire tensioner installation process, a wire tensioner fixing process, an electric wire pulling process, an electric wire separation process, an electric wire removal process, and a wire tensioner removal process. For this, as shown in Figure 37, a worker approaches the vicinity of the electric wire 30 on the utility pole while maintaining a safe distance using a live line bucket. At this time, the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 and a live line work stick S according to the present invention are prepared.
[0227] Here, the wire tensioner installation process is as follows:
[0228] In the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, when removing an already installed electric wire, the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 is installed on the rope 21 or dead end clamp 31 installed on the cross arm 20 of the electric pole.
[0229] For this reason, the wire tensioner 1 can be installed by using a hook 101 to hang it on a rope 21 as shown in (a) or by hanging it on a dead-end clamp 21 as shown in (b) as shown in Figure 38. This type of hanging work can be performed over a long distance using a live-line work stick S.
[0230] After that, the wire tensioner fixing process is
[0231] When removing an already installed electric wire in the indirect live line electric wire stringing method using the automatic direction changing pendulum type rotary drive ratchet wire tensioner for indirect live lines according to the present invention, the already installed electric wire 30 is clamped and fixed by the electric wire clip 1200 of the automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 for indirect live lines, as shown in Figure 39.
[0232] Then, the wire pulling process is
[0233] In the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, when removing an already installed electric wire, tension is applied to the already installed electric wire 30 to separate it from the cross arm 20 or the suspension insulator 32, as shown in Figure 40.
[0234] To this end, with the rotation prevention lever 440 inserted and installed in the stopping groove 413 of the outer ring 410, the rotation operating lever 200 of the wire tensioner 1 is rotated to cause the pendulum 600 to perform a rotating pendulum motion, thereby rotating the automatic reversal pole 800 and rotating the drum shaft 310 connected to the drum shaft operating plate 500, thereby winding the belt 1100 around the drum 300, thereby pulling the electric wire 30 and applying tension to the electric wire, thereby tightening the wire.
[0235] Then, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated in the forward direction using the live-line work stick. This causes the drum shaft 310 to rotate clockwise, pulling the belt 1100 and applying tension to the electric wire 30. At this time, the inside of the point where the electric wire 30 is fixed to the electric wire clip 1200, i.e., the connection portion with the dead-end clamp 31, becomes loose.
[0236] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 13 and 14, thereby rotating the drum shaft actuation plate 500 and winding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0237] That is, in the wire tensioning process, as described above, the drum shaft 310 is rotated clockwise by adjusting the counterclockwise rotation of the rotation actuation lever 200, thereby winding the belt 1100 and pulling the wire 30 to apply tension.
[0238] Then, the wire separation process is
[0239] When removing an already installed electric wire in the indirect live line wiring method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the already installed electric wire 30 is separated as shown in Figure 41.
[0240] For this purpose, when separating the electric wire 30 from the cross arm 20 or the suspension insulator 32 , first, the dead end clamp 31 of the electric wire 30 is separated from the cross arm 20 or the suspension insulator 32 .
[0241] Here, in the present invention, the method of separating the dead end clamp 31 is not limited to the above, and can be applied in various ways according to the general method of construction of power distribution lines.
[0242] After that, the electric wire removal process is as follows:
[0243] When removing an already installed electric wire in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the electric wire 30 separated in the electric wire separation process is lowered to the ground and removed, as shown in Figure 42.
[0244] To this end, the rotary operating lever 200 of the wire tensioner 1 is rotated to cause the pendulum 600 to perform a rotary pendulum motion, thereby rotating the automatic reversal pole 800 and rotating the drum shaft 310 connected to the drum shaft operating plate 500, thereby unwinding the belt 1100 from the drum 300, loosening the wire 30 and releasing the tension, and gradually lowering it to the ground.
[0245] After that, while maintaining a safe distance from the electric wire, the rotary actuation lever 200 is rotated clockwise using a live-line work stick, which rotates the drum shaft 310 counterclockwise, unwinding the belt 1100 and releasing the tension on the electric wire 30.
[0246] Meanwhile, in the present invention, the clockwise rotation adjustment of the drum shaft 310 is performed by the pendulum movement of the pendulum 600 caused by the operation of the rotation actuation lever 200, and the interlocking operation of the pole reversal key 900 and the automatic reversal pole 800 which are interlocked with the pendulum movement of the pendulum 600, as shown in Figures 15 and 16, thereby rotating the drum shaft actuation plate 500 and unwinding the belt 1100. A detailed description thereof will be omitted as it is the same as the above-mentioned operation.
[0247] That is, in the wire unwinding process, the drum shaft 310 is rotated counterclockwise by adjusting the clockwise rotation of the rotation actuation lever 200 as described above, thereby unwinding the belt 1100 and gradually lowering the wire 30 to the ground and removing it while releasing the tension on the wire 30.
[0248] Meanwhile, in the present invention, in order to prevent the electric wire 30 from falling off to the surrounding area during the process of lowering the electric wire 30 to the ground as described above, the electric wire 30 is connected with a rope or the like, and a worker can hold the rope to assist in the work of lowering the electric wire, or the electric wire 30 can be safely removed by grasping it using a live-line work stick.
[0249] After that, the wire tensioner removal process is as follows:
[0250] When removing an already installed electric wire in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner of the present invention, the installed indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner 1 is removed.
[0251] For this purpose, the wire tensioner installation process and the wire fixing process are carried out in reverse order, as shown in Figure 43. First, the live-line work stick S is used to release the connection state of the wire clip 1200 to the wire 30 in the reverse order of connection, and then the hook 101 is separated from the rope 21 in the reverse order of installation, thereby making it possible to remove the indirect live-line automatic direction-changing pendulum-type rotary drive ratchet wire tensioner 1.
[0252] As described above, in the indirect live line electric wire stringing method using the indirect live line automatic direction changing pendulum type rotary drive ratchet wire tensioner according to the present invention, the worker can easily remove the already installed electric wire while maintaining a safe distance from the electric wire 30 through the series of steps described above.
