Description

Catenary cleaning device {CLEANING DEVICE FOR CONDUCTOR RAIL}

The present invention relates to a catenary cleaning device, and more specifically, to a catenary cleaning device that can automatically clean the catenary and insulators while moving along a rail.

In general, railway vehicles are supplied with power through catenaries (overhead wires for electricity supply) to generate the power needed for the vehicle. These tram lines are installed on the ceiling, equipped with insulators for insulation, and continuously supply electricity through single wires that cross between spaced main lines.

The catenary system of the tram line can be divided into Overhead System, Third Rail System, and Rigid System. The processing type is a method of catenary wire using a catenary wire and is applied to general ground sections. However, since the tramline, a catenary wire, and an auxiliary catenary wire must be wired together, the required catenary height is high, making it difficult to apply to tunnel sections. In other words, in order to apply an overhead tram line to a tunnel section, the cross-sectional area of the tunnel must be significantly increased, resulting in excessive construction costs. In addition, daily inspection and maintenance are not easy due to the narrow space, and when the tram line is worn, the tram line is damaged. Of course, it has the disadvantage of having to replace the steering wire as well.

Meanwhile, the third rail type is a method of supplying power by installing a feed rail on the road surface or on the side. It has the advantage of being installed in a narrow space such as a tunnel, but due to the nature of the feed rail being placed on the ground, Due to the high risk of electric shock, it is only applied to certain special sections.

The rigid body type integrates the catenary into a rigid body and installs it using a separate structure such as a bracket. Since it does not require a clamshell wire, it is applied to sections where it is difficult to install a clamshell wire, such as tunnels.

Rigid catenaries are divided into T-Bar and R-Bar. In Korea, T-Bar is used in the DC 1,500V section with large current capacity, and R-Bar is used in the AC 25,000V section with low current capacity.

Meanwhile, in the past, various devices have been developed to automatically clean these tram lines, but in the case of R-bar, as more sophisticated tracking and cleaning technology is required compared to T-bar, a huge maintenance budget for cleaning is required, and a long time is required. There is a problem that the work effectiveness decreases depending on the cleaning cycle.

Hereinafter, the operation of the catenary washing device 1 according to an embodiment of the present invention will be described in detail.

While the vehicle unit 100 moves along the rail unit 10, the first detection unit 200 detects the displacement of the catenary unit 20.

More specifically, while the vehicle unit 100 moves along the rail unit 10, the detection control unit 260 detects the first detection member 240 based on the pressure data measured from the detection measurement unit 250. The first sensing member 240 is brought into contact with the catenary section 20 by adjusting the elevation height of the first sensing body portion 210 so that it can be continuously maintained within the set pressure range.

Accordingly, at least one of the first to thirteenth sensors (61 to 73) is pressurized by the tram line unit 20, and the sixth detection sensor unit 246 outputs a detection signal.

The control unit 700 receives a detection signal from the sixth detection sensor unit 246 and determines the displacement of the tram line unit 20 from the received detection signal.

More specifically, as the vehicle unit 100 moves toward the insulator unit 30, the second front washing nozzle 531 sprays washing water in the driving direction of the vehicle to primarily clean the surface of the insulator unit 30. Wash.

Thereafter, as the second front cleaning nozzle 531 passes through the insulator portion 30, the brush portion 540 contacts the surface of the insulator portion 30.

The brush unit 540 rotates about its central axis and removes foreign substances attached to the surface of the insulator unit 30.

In this process, the brush nozzle unit 550 sprays washing water toward the brush unit 540 to continuously remove foreign substances transferred to the surface of the brush unit 540.

As the brush unit 540 passes through the insulator unit 30, the second rear cleaning nozzle 532 sprays washing water in a direction opposite to the driving direction of the vehicle to finally clean the surface of the insulator unit 30.

Thereafter, when the second detection unit 300 detects the insulator unit 30 located on the left side of the catenary unit 20, the control unit 700 detects the second washing unit 500 installed on the left side of the vehicle unit 100. The second washing body part 510 provided in is moved upward, and the second washing body part 510 provided in the second washing part 500 installed on the right side of the vehicle unit 100 is moved downward.

Afterwards, the control unit 700 operates the second washing nozzle unit 530, the brush unit 540, and the brush nozzle unit 550 provided in the second washing unit 500 installed on the left side of the tram line unit 20. The insulator part 30 connected to the left is cleaned by the above-described operation.

Meanwhile, as the second washing body part 510 is raised above a predetermined height, the third washing nozzle part 610 is disposed above the tram line part 20. In this case, the third cleaning nozzle unit 610 is disposed on the second cleaning base unit 520 on the opposite side of the second cleaning nozzle unit 530 with respect to the catenary unit 20, thereby preventing collision with the insulator unit 30. This can be prevented. Thereafter, the third washing nozzle unit 610 sprays washing water toward the upper side of the tram line portion 20 to clean the upper side of the tram line portion 20.

In addition, the control unit 700 controls the washing heating unit 460 to heat the washing water during the washing process of the catenary unit 20 and the insulator unit 30 as described above, thereby sending the high temperature washing water to the first washing unit 400. , can be supplied to the second washing unit 500 and the third washing unit 600.
