In addition, the vertical support 110 may be a winch auxiliary arm that is a basic component of a live work vehicle. In this case, the rope mounting roller 160 formed on the upper part of the winch auxiliary arm is removed, and the horizontal support coupler 130 is coupled to the position of the rope mounting roller 160.
Figure 4 is a detailed block diagram showing a horizontal support coupling portion of the wire support according to an embodiment of the present invention. In FIG. 4, the horizontal support coupling part 130 includes a vertical support fastening part 131 coupled to a vertical support 110 at a lower portion thereof, and a horizontal support fastening part 134 coupled to a horizontal support 120 at an upper portion thereof. do. The horizontal support fastener 134 may be configured to rotate at the top of the vertical support fastener 131. The vertical support fastening part 131 is coupled to the vertical support 110 by the vertical support fixing bolt 135. The vertical support fixing bolt 135 is inserted through the bolt fastener 132 formed on the side of the vertical support fastening portion 131 is tightened to the vertical support (110). The bolt fastener 132 is formed to be vertically long, and may allow various bolt fasteners 132 to be drawn in according to the type of the active work vehicle. The horizontal support fastening unit 134 is formed with a horizontal support fixing bolt 135, to couple the horizontal support fastener 134 and the horizontal support 120.
Next, a configuration in which the wire support is coupled to the live work vehicle will be described with reference to FIG. 5. As shown in FIG. 5, the vertical support 110 of the wire support 100 is coupled to the winch of the live work vehicle. Thereafter, the rope 170 connected to the winch is connected to the rope connecting ring 150 formed at the lower portion of the vertical support 110. The worker may ride on the insulation bucket 210 of the live work vehicle and wind the rope 170 using the winch to move the vertical support 110 upward. In this case, it is preferable to perform fine adjustment of position using a winch after operating the boom 200 of a live work vehicle to bring the electric wire support 100 close to the work area of a pole. After lifting the wire, the fixing pin 180 can be plugged into the lower portion of the vertical support 110 to fix the vertical support 110 more firmly.
Next, the process of performing the wire conducting work using the wire support 100 will be described.
Figure 6 is a flow diagram of the wire wire work using the wire support according to an embodiment of the present invention. As shown in Figure 6, in order to perform the replacement of the LP insulator, replacement of the pin length, changing the length of the pole, wire wire work, etc. in the overhead power supply system, first fully protect the complete iron, insulators and wires (S100) . The above-mentioned protection operation can use a conventionally well-known method.
Then, the wire support 100 is coupled to the live work (S110). Specifically, the wire support 100 is assembled by combining the vertical support 110, the horizontal support 120, and the vertical support coupling unit 130. At this time, it can be configured to use the winch auxiliary arm that is basically mounted on the live work vehicle as the vertical support (110). In this case, the rope mounting roller 160 mounted on the upper part of the winch auxiliary arm may be removed first, and then assembly with the remaining devices may be performed. Thereafter, the assembled wire support 100 is coupled to the winch of the live work car, and connects the rope 170 connected to the winch to the rope connecting ring 150 of the vertical support 110.
At this time, an appropriate number of insulating rollers 140 may be coupled to the horizontal supporter 120 (S120). 7A shows the actual appearance of this operation.
Subsequently, the wire support 100 is moved to the lower part of the wire by operating the boom 200 of the live work vehicle. After that, the winch of the live work vehicle is wound and the insulating roller 140 of the wire support 100 is moved. Position the wires to support the work correctly. Thereafter, further winding the winch, and lifts the wire support 100 to the upper wire to wire (S130). This workflow is illustrated in Figure 7b.
Thereafter, the wiring work such as replacing the LP insulator, replacing the pin holder, changing the owner, installing an allotment holder, and replacing the pole is performed (S140). When all of the above work is completed, the winch is reversed by unwinding and the wires that have been transferred are returned to their original state (S150).
Through this process, it is possible to easily perform the wire wire work for performing each power distribution work in the live state.
8A and 8B illustrate a process of replacing the LP insulator 310 after performing the wire wiring operation. As shown in FIG. 8, it is possible to replace only some of the LP insulators 310 by combining with the horizontal support coupling unit 130 so that the horizontal support 120 is biased to one side.
9A and 9B, a process of replacing the pin head post after performing the wire wire work is shown. As shown in FIG. 9, the pin length column 320 may be replaced after the power lines of the three-phase LP insulators wired on the pin length column 320 are all wired upward.
10A and 10B show the operation of replacing the built-in finished iron after performing the wire wire work. As shown in FIG. 10, after all the power lines of the three-phase LP insulator are upwardly wired, the built-in wrought iron 330 may be replaced.
11A and 11B show the operation of replacing the pole after performing the wire wire drawing operation. As shown in FIG. 11, the electric pole 340 may be replaced after the electric wires of the three-phase LP insulator wired on the pin long pole of the electric pole 340 are all wired upward.
The wire support having the above configuration and the wire discharging method using the same have the effect of simply attaching the wire support to the live work vehicle and performing the wire work accurately and safely using the boom and the winch of the live work vehicle. have.
In addition, by using the wire support of the configuration as described above, compared to the conventional method, the number of tools for the up-conversion of the power line is small, it is possible to perform the work quickly, and there is no need to install the wooden rod on the pillars for safe construction There is a possible effect.
The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
