The main pipe 28 is connected to the air discharge port of the air pressure feeding means (compressor) 22. The main pipe 28 has a length and flexibility that allow relative swinging movement between the driven trolley 8 and the hanger 9.

In the embodiment shown in FIG. 3, the nozzles 23 are arranged in series in the axial direction of the vertical steering roller 15. However, the height of the guide rail 1 is low, and therefore, When the width is narrow, the nozzles 23 are arranged so that a part thereof overlaps in the traveling direction of the electric vehicle.
1 can be reduced in overall vertical width. Further, each nozzle unit 23 is inclined obliquely downward so that air is effectively jetted to a portion where dust easily accumulates, such as each groove of the power supply line 5 and the upper surface of the lower rail portion 3 of the guide rail 1. Can also be configured.

As shown in each figure, the hood 30 covers the side surface of the guide rail 1 between the vertical steering rollers 14 and 15 on the side where the nozzle 21 is located, and has a notch in which the trolley 8 and the like are fitted. A part 32 is provided, and an intake port 33 is provided at one end. The hood 30 is inserted into the notch 32
The trolley 8 is fitted to the outside of the trolley 8 by using the nozzle 2 in the hood portion 30a on one side.

As shown in FIG. 1, the dust collecting means 31 includes a replaceable dust collecting filter 34, an intake fan 35, and a motor 36 for driving the intake fan.
And a drawer-type tray for collecting collected dust. The suction port of the dust collecting means 31 and the suction port 33 of the hood 30 are connected by a flexible suction pipe 38.

According to the electric vehicle with the power supply line cleaning device of the present invention having the above-described structure, the supporting horizontal axis wheel 10 in the drive trolley 7 of the electric vehicle 6 is mounted on the power supply line 5 with the current collecting means 19 and the electric vehicle 6. When the electric vehicle 6 is driven to rotate along the guide rail 1 by rotating the motor 17 driven by the electric power supplied through the control panel, the intake of the pneumatic feeding means 22 and the dust collecting means 30 is simultaneously performed. By operating the fan driving motor 36 with electric power supplied from the power supply line 5 through the control panel mounted on the power collection means 19 and the electric vehicle 6, each of the nozzles 21 in the power supply line cleaning device 20 Air is injected from the nozzle unit 23 toward the power supply line 5, and the power supply line 5 attached to the running electric vehicle 6 and the guide rail 1 in the vicinity of the power supply line 5 and the power collection unit 19.
And dust can be automatically cleaned by blowing off dust containing abrasion powder, and at the same time, placing the dust on the airflow flowing into the hood 30 from the gap between the hood 30 and the guide rail 1 to collect dust. 31 can be collected.

The electric vehicle to which the cleaning device of the present invention can be mounted is limited to a suspended electric vehicle 6 suspended from one guide rail 1 via a trolley as in the above embodiment. However, the apparatus of the present invention can be configured using a mount-type electric vehicle supported on a single guide rail or a pair of left and right guide rails installed on the floor surface or below the floor surface. In addition, the nozzle 21 and the hood 3
The position where the 0 is attached is not limited to the load trolley (cart) that receives the load of the electric car as in the above-described embodiment, and the frame of the electric car or the front trolley connected to the load trolley (cart) via the load bar. It is also possible to attach the nozzle 21 and the hood 30 to a (trolley), a rear trolley, or the like. Furthermore, the electric vehicle that constitutes the apparatus of the present invention may be configured to also serve as the electric vehicle for transportation as in the above-described embodiment, or may be configured as an electric vehicle exclusively for cleaning.

Further, in the above-described embodiment, the nozzle 21 and the hood 30 are individually and detachably attached to the electric vehicle side. However, as shown in FIGS.
A nozzle 21 may be mounted inside the hood 40 to integrate the two, and the mounting bracket 41 attached to the hood 40 may be configured to be mounted at an appropriate location on the electric vehicle. In this case, the distributor 27 can be provided outside the hood 40. Each of the nozzles 23 constituting the nozzle 21 has a pipe connecting shaft 23b at its base penetrated through a substrate 42 attached to a hood 40, and a set screw 23c.
The nozzles 23 are fixed to one connecting plate 43 with the mounting bolts 25 so that the flat discharge ports 23a are aligned in a straight line, and are integrated.

[0018]

As described above, according to the electric vehicle with the power supply line cleaning device of the present invention, dust adhering to the power supply line adjacent to the running electric vehicle and the guide rail near the power supply line is ejected from the nozzle. Although it is possible to automatically clean by blowing off with air, in particular, in the present invention, instead of directly scattering the dust including the power supply line blown off by the nozzle and the abrasion powder of the current collector, the power supply line is cleaned. Since the hood can be automatically collected by using a hood that covers a certain area including a portion opposed to the nozzle and a dust collecting unit that collects air from the hood, the dust is scattered in the air. It is possible to solve the problems, that is, problems such as a decrease in the surrounding sanitary environment, malfunctions of the various types of machinery installed around the device, and a reduction in the service life thereof.

According to the second aspect of the present invention, the position of the nozzle in the traveling direction of the electric vehicle coincides with or near the axial center position of the vertical shaft roller for steering of the trolley. , And having a flat discharge port parallel to the axis of the vertical shaft roller for steering, the discharge port of the nozzle also in the horizontal curve path portion where the guide rail curves in the horizontal direction The distance between the power supply line and the power supply line can be changed little or only slightly. Therefore, the interval between the discharge port of the nozzle and the power supply line can be sufficiently reduced, and the discharge port of the nozzle has a flat shape parallel to the axis of the steering vertical shaft roller. Even if the pressure of the air supplied to the nozzle is reduced, the cleaning effect by blowing off dust can be sufficiently exhibited. This makes it possible to use a small and lightweight air-conveying means with low power consumption, and its economic effect is enormous.

According to the third aspect of the present invention, since only the hood can be removed, it is possible to adjust the mounting position and angle of the nozzle while checking the relative positional relationship between the nozzle and the power supply line. It will be easier. Claim 4
According to the configuration described in (1), only the hood needs to be attached to the electric vehicle side, and the hood can be used also as the bracket for supporting the nozzle, so that the structure is simplified and the cost can be reduced.
