In order to install a power transmission line and a communication line in a power transmission tower or a utility pole, which is a unit for installing the power transmission line and the communication line in the air at a predetermined height, a method of installing a temporary line and then pulling up a main line is used.
In order to connect such a line from one transmission tower or utility pole to another, a method of directly moving to the ground by a worker is used, but this method may have problems of long working time or being greatly affected by the terrain and features.
Also, a method of transferring a line into the air using a manned aircraft may be used, but this method is too costly to operate at night due to the operation of the aircraft, and may generate large noise.
As a conventional invention for transferring a line by an unmanned aerial vehicle by solving such problems, korean laid-open patent publication No. 10-2014-0140978, "a system for installing power transmission towers for power transmission line" has been proposed and disclosed.
Although not an invention for directly transferring a line for installing a power transmission line, an "unmanned aerial vehicle type life saving equipment drop device" disclosed in korean patent laid-open publication No. 10-1535401 and an "unmanned aerial vehicle attachment mechanism" disclosed in korean utility model laid-open publication No. 20-0479018 have been proposed and disclosed as inventions related thereto.

However, the conventional techniques described above are only systems or devices for transporting a reel portion around which a wire is wound or an article by being attached to an unmanned aerial vehicle, but do not disclose a solution to this problem when the wire or the article is not separated, such as when the wire wound around the reel portion is wound and cannot be unwound.
The gripping portion and the support unit are suitable for transferring articles as independent units, but are not suitable for transferring long and connected lines.
Therefore, there is a need for an invention relating to a device that specializes in the transfer and separation of lines during the line-erecting work by an unmanned aerial vehicle and solves such problems when the transferred lines are not separated.

The present invention relates to a line-erecting device and a line-erecting method using the same, which are mounted on an unmanned aerial vehicle, and more particularly, to a line-erecting device mounted on an unmanned aerial vehicle, the line-erecting device including: a first motor member 100 which is composed of a servo motor and has a first motor shaft protruding to the outside; a rotary hanger 110 having two open-close type slots 111 formed at one side thereof and being rotated by being coupled to the first motor shaft; a separation preventing member 120 having a separation preventing groove 121 formed on one side thereof for closing the open/close type groove 111; and a cutting member 130 having a hollow portion in which a blade portion 132 operated by an external force is built, and having first through holes 131 formed in both side portions to be symmetrical to each other with respect to the hollow portion, the first through holes being adapted to communicate the hollow portion with the outside, the line construction method being adapted to a line construction work using an unmanned aerial vehicle, the method including: an installation step of installing a line erection device on the unmanned aerial vehicle; a line connection step of connecting lines to the rotary hangers 110 provided in the line erection device mounted on the unmanned aerial vehicle; a load applying step of applying a load by connecting a water bag 160 to the circuit; a flying step, wherein the unmanned aerial vehicle takes off and flies by using a control device of a user; and a separation step for separating the line from the rotary hanger 110.
Hereinafter, an embodiment of the line installation device mounted on the unmanned aerial vehicle according to the present invention will be described in detail with reference to the drawings.
The present invention relates to a line erection device mounted on an unmanned aerial vehicle, and more particularly to a line erection device for use in line erection work for erecting a power transmission line in a power transmission tower performed in advance.
The present invention is characterized in that the line-erecting device is attachable to an unmanned aerial vehicle, and the line is moved to a target position by the unmanned aerial vehicle while being connected to the line-erecting device and then separated from the line-erecting device.
The target position is a position above a power transmission tower to which the line is to be transferred, and more specifically, a position at which the unmanned aerial vehicle can easily hand over to a worker located at the power transmission tower when the line transferred by the unmanned aerial vehicle is separated from the line installation device.
Also, the present invention is applicable to work for erecting a communication line on a utility pole in addition to work for erecting a power transmission line on a power transmission tower, but for convenience of explanation, explanation of the communication line will be omitted below.
The line is a general name of a plurality of lines such as a line, a steel wire, a stranded wire, and a rope having a weight that can be transferred by the unmanned aerial vehicle.
First, as shown in fig. 1, the line-erecting device according to the present invention includes a rotary pendant 110 as a component for connecting or separating a line transferred by an unmanned aerial vehicle, a first motor member 100 including a servo motor having a first motor shaft protruding to the outside and two open/close grooves 111 having two open sides are formed on one side of the rotary pendant 110, and the rotary pendant 110 is rotated by being coupled to the motor shaft.
The rotary pendant 110 is configured to directly connect and disconnect a line transferred by the unmanned aerial vehicle, and the rotary pendant 110 is configured to have two openable grooves 111 having open sides formed in one side of the rotary pendant 110, and the rotary pendant 110 is configured to have protrusions 112 formed on both sides of the openable grooves 111 by forming the openable grooves 111.
The protrusion 112 is a component for preventing the separation while connecting the line to the rotary hanger 110, and the protrusion 112 cannot be formed in a normal groove shape in which only one side is opened, but the opening and closing groove 111 has a shape in which both sides are opened, and thus the protrusion 112 is formed on both sides of the opening and closing groove 111 in the rotary hanger 110.
As an example of connecting a line to be transferred by the drone to the rotary pendant 110 through the open/close type groove 111 and the protrusions 112, a worker may form an end of the line in a ring shape and hang a ring on one of the protrusions 112.
Then, after connecting additional fixing members each having a length longer than the interval between the protrusions at one end of the line, the worker places the fixing members between the protrusions 112.
At this time, the other end of the wire is suspended downward of the rotary hanger 110 through one of the two open sides of the openable groove 111, and thus the fixing member is continuously placed between the protrusions 112.
However, the manner of connecting the line to the rotary hanger 110 is not limited to the above-described manner, and any manner may be used as long as the line can be fixed to the rotary hanger 110.
The rotary hanger 110 is coupled to the first motor shaft to rotate in a forward direction and/or a reverse direction at a predetermined angle, thereby preventing a line connected to the rotary hanger 110 from being separated or disengaged.
That is, as shown in fig. 2a to 2b, after the worker connects the line to be transferred by the unmanned aerial vehicle to the rotary pendant 110, the worker drives the first motor member 100 to insert a part of the openable groove 111 and the protrusion 112 into the separation preventing groove 121 described below, thereby preventing the line from being separated.
As shown in fig. 2c, when the drone reaches the target position, the worker drives the first motor member 100 to direct the openable groove 111 and the protrusion 112 downward of the drone, thereby separating the line from the rotary pendant 110.
It is obvious that the openable groove 111 and the protrusion 112, which are rotated by the first motor part 100 to change positions, are not provided toward the lower side of the drone after the line is connected, so as to prevent the line from falling.
Therefore, it is preferable that the first motor unit 100 for rotating the rotary hanger includes a servo motor capable of rotating in a forward direction, which is a clockwise direction, and/or in a reverse direction, which is a counterclockwise direction, at a predetermined angle.
The line installation device of the present invention includes a separation preventing member 120 having a separation preventing groove 121 formed on one side thereof to close the open/close type groove 111.
The separation preventing member 120 is provided at an intersection where the rotary hanger 110 rotates and moves, and has a separation preventing groove 121 formed at one side thereof to prevent collision with the rotary hanger 110, as a component for blocking and closing an entrance of the openable groove 111 to prevent separation of a wire connected to the rotary hanger 110.
The distance between the rotary hanger 110 and the separation preventing member 120 is preferably formed to prevent the rotary hanger 110 and the separation preventing member 120 from colliding with each other because the separation preventing groove 121 is formed, although the distance between the rotary hanger 110 and the separation preventing member 120 is formed to allow the rotary hanger 110 to collide with the separation preventing member 120 when the separation preventing groove 121 is not formed in the separation preventing member 120.
That is, the depth of the separation preventing groove 121 may be changed according to the interval between the rotary hanger 110 and the separation preventing member 120.
The separation preventing groove 121 is formed as a groove formed along the length direction of the separation preventing member 120, and steps are formed at both sides of the groove, which is the same as a general groove shape, but two end portions or one end portion is opened unlike the general groove shape, so that it can be used as a passage for the end portion to enter and exit when the rotary hanger 110 is rotated.
That is, the distal end portion of the rotary hanger 110 enters the separation preventing groove 121 through the open distal end of the separation preventing groove 121, and the line entering from the inlet of the open/close type groove 111 and connected to the rotary hanger 110 is separated from the inlet of the open/close type groove 111 by the stepped portion.
However, the structure in which the distal end of the separation preventing groove 121 is opened is not limited to the case where the distal end of the rotary hanger 110 and the distal end of the separation preventing member 120 collide with each other when the rotary hanger 110 rotates, and may not be opened when the distal end of the separation preventing member 120 is separated from the radius of rotation of the rotary hanger 110.
As an example of the separation preventing member 120, the separation preventing member 120 may be positioned above the rotary hanger 110, and the separation preventing groove 121 may be formed on a lower surface of the separation preventing member 120.
In another embodiment of the separation preventing member 120, the separation preventing member 120 may be positioned at a side of the rotary hanger 110, and the separation preventing groove 121 may be formed on a side surface of the separation preventing member 120 facing the rotary hanger 110.
That is, the rotary hanger 110 and the separation preventing member 120 may be always in the same form, and the form in which the rotary hanger 110 and the separation preventing member 120 are disposed in the line installation device may be variously changed, so that the rotation direction and the rotation angle of the first motor shaft for separating the line by changing the position from the original position such that the openable groove 111 and the protrusion 112 face downward should be different, which is obvious.
However, the separation preventing member 120 is not preferable because it is located below the rotary hanger 110 and acts as an obstacle in the process of separating the wire connected to the rotary hanger 110 downward.
As shown in fig. 3a, the present invention is characterized in that the wire routing device of the present invention includes a cutting member 130 having a hollow portion formed therein for accommodating a blade portion 132 operated by an external force, and first through holes 131 formed in both side portions of the cutting member 130 to be symmetrical to each other with respect to the hollow portion, the first through holes being in communication with the hollow portion and the outside.
The cutting member 130 is positioned below the rotary hanger 110 to pass the wire, and has a blade 132 built therein to cut the wire when the wire is not detached, as a component for preventing the wire from being detached by the rotation of the rotary hanger 110.
The hollow portion is a passage through which the wire passes and a passage through which the blade portion 132 moves, and an inlet and an outlet through which the wire passes through the hollow portion are formed by the first through holes 131.
When the cutting member 130 is mounted to the line-erecting device, the first through holes 131 are preferably formed to face upward and downward of the cutting member 130 in a process of separating and separating the line from the rotary hanger.
In the case where the terminal portion of the line is connected to the fixing member, the diameter of the first through hole 131 is preferably longer than the length of the fixing member.
The present invention is characterized in that the blade 132 is operated to cut one position of the line only when the line needs to be separated from the rotary hanger 110, and receives an elastic force from a spring 133 located inside a hollow portion of the cutting member 130, as shown in fig. 3a to 3 b.
Further, the present invention is characterized in that the cutting member 130 includes:
a second through hole 134 for communicating the hollow portion with the outside; and a fixing latch 135 for moving the spring 133 along the second through hole 134.
The second through hole 134 is
And thus may be divided into a vertical portion formed along the up-down direction and a horizontal portion formed along the left-right direction.
The fixing latch 135 is connected to the spring portion 133 at one end thereof, penetrates the second through hole 134, and protrudes to the outside of the cutting member 130 at the other end thereof, generates a compression force to the spring portion 133 in a state of being caught by the vertical portion, moves from the vertical portion to the horizontal portion, releases the compression of the spring portion 133, and generates an elastic force.
In this case, the line-erecting device according to the present invention includes a striking part 113 for striking the fixing latch 135 when the rotary hanger 110 is rotated, as a component for moving the fixing latch 135 hung on the vertical part to the horizontal part, and protruding to the outside of the rotary hanger 110.
The striking part 113 is formed to have a length capable of striking the fixing lock 135 suspended on the vertical part when the rotary hanger 110 is rotated and to be inclined at a predetermined angle, and is movable along the horizontal part by moving the fixing lock 135 downward and flexibly separating from the vertical part when striking.
The end of the line may be directly formed in a loop shape to be moved by the drone, but it is difficult to form a loop shape in characteristics of the line or it is necessary to pass through a cutting process after that, and thus a loss occurs, so that it is preferable to connect other additional lines at the end of the line to form a loop shape.
The line installation device of the present invention is characterized by further comprising a hot wire member.
As shown in fig. 4a to 4b, the heat-ray member is a component for cutting the wire by high-temperature heat to forcibly separate the wire from the rotary hanger 110, and includes: a second motor member 141 composed of a servo motor having a second motor shaft protruding to the outside; a hot wire moving unit 142 having one side coupled to the second motor shaft and the other side rotating around the second motor shaft; a heating wire portion 143 connected to the other side of the heating wire moving portion 142; and a heating unit for heating the heating wire unit 143.
The second motor member 141 is configured as a servo motor in the same manner as the first motor member 100, and thus can rotate in a clockwise direction and/or a counterclockwise direction by a predetermined angle, and one side of the hot wire moving part 142 is coupled to the second motor shaft, and thus the other side thereof is axially rotated by the forward rotation or the reverse rotation of the second motor member 141, thereby axially rotating the heater part 143.
At this time, since the heat wire portion 142 is rotated in half with the second motor shaft as an axis, the heat wire portion 143 is also rotated in half, and cuts a portion of the wire which is located within a half rotation radius range in a state of being suspended downward of the cutting member 130 through the first through hole 131 by heat.
The heating wire portion 143 may be formed of a nichrome wire, a copper wire, or the like having high thermal conductivity.
The heating unit is a component that generates heat by driving the second motor member 141 or a heating means provided separately, and a nichrome wire, a copper wire, or the like that conducts heat generated by the heating unit 143 is provided in a section of a path in which the heating unit 143 rotates in half, so that the heating unit 143 is heated by friction with the heating unit 143.

In addition, in the case where an additional heating unit is provided in the heating unit, the control unit may drive and stop the heating unit.
Hereinafter, an embodiment of the line erecting method of the present invention will be described in detail with reference to the drawings.
First, the line erection method of the present invention is applicable to work for erecting a line using an unmanned aerial vehicle, and is characterized by including an installation step of installing a line erection device on the unmanned aerial vehicle.
The unmanned aerial vehicle can take off in the state of installing the line erection device as long as the unmanned aerial vehicle has sufficient size and power, can be operated on the ground, and is not limited by types and forms.
Preferably, the line-erecting device is installed at a lower side of the unmanned aerial vehicle so as to prevent a weight center of the unmanned aerial vehicle from moving and a locking phenomenon of a connected line, which may occur due to installation of the line-erecting device.
The line erecting method according to the present invention is characterized by including a line connection step of connecting lines to the rotary hangers provided in the erecting device.
Preferably, the line connecting step is performed after the mounting step, but is not limited thereto, and the worker may use a method in which the end of the line to be transferred by the drone is formed in a ring shape and an upper ring is hung on one of the protrusions 112 formed on both sides of the open-close type groove 111 of the rotary hanger 110.
In this case, the end of the line may be directly formed in a loop shape to be transferred by the drone, but it is difficult to form a loop shape in terms of the characteristics of the line or it is necessary to perform a cutting process thereafter, and thus a loss occurs, and it is preferable that another additional line is connected to the end of the line to form a loop shape.
Also, the worker may use a manner of placing the fixing member between the respective protrusions 112 after connecting an additional fixing member having a length longer than the interval between the respective protrusions 112 at the end of the line, but is not limited to this manner.
The method for erecting a wire according to the present invention includes a load applying step of applying a load by engaging the water bag 160 with the wire.
The load applying step may be performed after the mounting step or after the line connecting step, but may be performed first before the mounting step or before the line connecting step.
The water bag 160 is a component for suspending the line below the unmanned aerial vehicle by applying a load to the line connected to the unmanned aerial vehicle and being transferred.
The opposite end of the line, the end of which is connected to the aforementioned drone, is fixed in a position on the ground, on the transmission tower, etc., and the aforementioned drone should be close to the staff member in order to hand over such line to the staff member located on another transmission tower spaced apart from the aforementioned transmission tower.
In a general state where the line is connected to the drone as shown in fig. 5a, when the line is handed over, a worker needs to approach the drone, and thus there is a risk of a collision possibility increasing, and as shown in fig. 5b, the line is connected to the water bag 160 to apply a load so as to hang down, so that the worker can easily take over the line.
The water bag 160 may hang the line below the drone to prevent the line from being entangled with the drone.
Preferably, the water bag 160 is formed of a material such as plastic, so that the water bag is easily broken and the internal fluid is discharged to minimize damage to the ground in case the water bag 160 is separated from the line and dropped.
Further, the present invention is characterized in that the water bag 160 is formed of a transparent material projected inside so as to be easily visible to a worker, and a fluorescent substance emitting light by light energy or a pigment substance imparting color to the fluid is added to the fluid filled in the water bag 160.
If the water bag 160 is made of a transparent material and filled with a transparent fluid such as water, it may be difficult for a worker located at the power transmission tower to recognize the position of the water bag 160, and as a means for solving such a problem, a fluorescent substance or a pigment substance is added to the fluid so that the water bag 160 can be easily recognized even at a remote location.
In this case, one of the fluorescent substance and the coloring substance may be used during daytime operation, but the fluorescent substance is preferably used during nighttime operation.
The line erecting method of the present invention is characterized by including a flying step of flying the unmanned aerial vehicle on the line by using a control device of a user.
The manipulator is a general manipulator that can remotely manipulate the drone, but as a configuration for achieving the object of the present invention of separating the drone in the air by transferring the line, it is necessary to attach an additional working device or the like for driving the first motor member 100 and/or the second motor member 141 to the manipulator.
As an example of the flying step, the starting position of the unmanned aerial vehicle may be a transmission tower and the ground near the position where the transmission tower is located.
Thereafter, the drone flies above another transmission tower spaced from the one transmission tower, so that the staff at the transmission tower or the utility pole can take over the line connected to the drone.
The line erecting method according to the present invention includes a separation step of separating the rotary hanger 110 from the line.
An additional working device or the like for driving the first motor part is also attached to the operating device, so that a user operating the operating device drives the first motor part after the person at the transmission tower takes over the line.
In addition, the separation step further includes a cutting step of cutting the strand or the cable by the blade 132 or the hot wire 143.
The same applies to the case where the rotary hanger 110 rotates to separate the line when the first motor member 100 is driven, and the line is forcibly separated by the blade part 132 and/or the heater part 143 when the line is not separated from the rotary hanger 110.
At this time, the second motor part 141 for driving the hot wire part, which is another forcible separation unit attachable to the blade part 132 or provided instead of the blade part 132, may be driven simultaneously when the first motor part 100 is driven. Alternatively, an additional working device for driving the second motor part 141 may be additionally provided to the manipulating device so as to be driven separately from the first motor part 100.
The above-described embodiments are provided as examples to fully convey the technical idea of the present invention to those skilled in the art to which the present invention pertains, and the present invention is not limited to the above-described embodiments and can be embodied in other forms.
That is, the line erecting device attached to the unmanned aerial vehicle and the line erecting method using the same according to the present invention are applicable to not only line erecting work for erecting a power transmission line on a power transmission tower, which is performed in advance, but also work for erecting a communication cable on a utility pole.
In the drawings, the width, length, thickness, and the like of the constituent elements may be exaggerated or reduced for convenience of explanation.
In addition, like reference numerals denote like components throughout the specification.
