Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a cleaning device used for cleaning a train or an aircraft having a streamlined head portion or a head portion with many irregularities.

[0002]

[Prior art]

 Conventionally, high-speed vehicles that have a streamlined leading edge, for example, the leading edge of a Shinkansen, have a bad visibility due to collisions with insects such as worms during driving, so cleaning work is performed at vehicle depots to remove the dirt. Be done. This work is done manually by using a mop with a handle to apply the cleaning chemicals and washing them off with water spray from the hose until the vehicle turns back. Further, a vehicle b is made to travel between columnar nozzles a and a for injecting a chemical liquid as shown in FIG. 1, and then a rotating brush c oscillated by an arm as shown in FIG. There is also sold a device for cleaning the streamlined head portion d by reciprocating along it, and further for cleaning both sides of the vehicle with an upright rotating brush e as shown in FIG.

[0003]

[Problems to be solved by the device]

 Until the vehicle departs at the above depot, cleaning and other maintenance and inspection of the passenger compartment will be carried out, so the vehicle cannot be moved and the washing work cannot be carried out. However, in the case of the Shinkansen, it took about 15 minutes for about 7 people, and there were few people who wanted the work to be dangerous and dirty. In addition, the cleaning device with a rotating brush as shown in Fig. 2 has the drawback that the impact of the brush may damage the body finely, and it is not easy to install because of its large size. Furthermore, the rotating brush is expensive and easily worn, so the cost is high. There is an inconvenience. In order to solve such inconvenience, the applicant provided a nozzle for ejecting a chemical solution and high-pressure water on an arm provided on a traveling carriage, and moved the nozzle along the head part of the vehicle by rocking the arm. I thought about that. However, when cleaning the head of a vehicle's streamline, the nozzle must move in a substantially fan-shaped area as seen in the plan view of FIG. Like a commercial robot, a base f that moves in the X axis direction and a base g that moves in the Y axis direction along the base f are provided on a traveling carriage h, and a chemical solution and high-pressure water are ejected from a nozzle i provided in the base g. With such a configuration, since the base f projects in the width direction, it is difficult to perform a cleaning operation in a narrow place where a vehicle or the like exists laterally. Even if a general cylindrical coordinate robot or polar coordinate robot is used, it takes a considerably long stroke to move the nozzle so that it does not come into contact with the vehicle head in the cleaning range shown in the figure. There is a risk that the robot arm will touch the vehicle on the side. Furthermore, it is desirable that the arm that moves the nozzle can be housed compactly in the bogie in order to prevent danger while the traveling bogie is moving and to store it.

An object of the present invention is to provide a cleaning device capable of freely operating a nozzle in a narrow area and accommodating its operating member compactly.

[0005]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, a swivel arm that swivels horizontally around a vertical first rotary shaft is provided on the upper surface of a traveling carriage, and a vertical second rotary shaft is provided above the tip of the rotary arm. A swivel that swivels horizontally is provided at the center, and a first undulating arm is movably mounted on the swivel, and a second undulating arm equipped with a cleaning nozzle is movably mounted on the tip of the first undulating arm. In the cleaning device, the first undulating arm is provided so as to lie down to a position that vertically overlaps the turning arm, and the second undulating arm is provided so as to be bent vertically downward along the front surface of the traveling carriage.

[0006]

[Action]

 The above traveling carriage is positioned in front of the item to be washed such as the Shinkansen, and the nozzle is brought close enough not to touch the item to be washed to eject chemical liquid and high-pressure water for washing, but the movement of the nozzle in the width direction is not possible. The swivel can be swiveled, and the vertical and forward / backward movements are performed by the first undulating arm and the second undulating arm on the swivel, so a wide base is not required and washing is possible even in a narrow space with side obstacles. You can work. Also, since the first undulating arm lies parallel to the swivel arm and the second undulating arm bends vertically downward along the front surface of the traveling carriage, it can be compactly housed so that it does not greatly protrude from the traveling carriage, It enables safe movement and storage of trolleys in tight spaces.

[0007]

 An embodiment of the present invention will be described with reference to the drawings. In FIGS. 5 and 6, reference numeral 1 indicates a self-propelled traveling vehicle equipped with wheels 2 for rail traveling, and a cover of the traveling vehicle 1 is provided. A cleaning liquid chemical pump 5 driven by an electric motor 4, a high-pressure water pump 6, a rechargeable battery 7, a water tank 8, a cleaning liquid chemical tank 9, and a controller 10 are mounted in the enclosed room. A swivel arm 11, a swivel base 12, a first hoisting arm 13 and a second hoisting arm 14 are provided on the traveling carriage 1, and the second hoisting arm 14 is configured to be extendable and retractable at its tip. A cleaning nozzle 15 is attached to the.

The swivel arm 11 has one end attached to the upper surface of the traveling carriage 1 so as to swivel horizontally about a first rotary shaft 16 which is vertical, and a swivel arm 11 has a second swivel arm vertically attached to the upper end of the other end. A swivel base 12 is mounted which swivels horizontally about a rotary shaft 17. A first undulating arm 13 undulating around a horizontal shaft 18 is attached on the swivel base 12, and a second undulating arm 14 is movably attached to the tip of the first undulating arm 13. The first undulating arm 13 is provided with a parallel link 19 so that the second undulating arm 14 is undulated vertically by controlling the operation of the parallel link 19. The operations of the swivel arm 11, the swivel base 12, the first undulating arm 13, the expansion and contraction of the second undulating arm 14 and the swiveling of the nozzle 15 are performed by an electric motor, and the operation is controlled by the controller 10. The nozzle 15 is attached to the tip of the second member 22 through a first member 20 that swings up and down the tip of the second undulating arm 14 and a second member 22 that horizontally swivels at the tip of this member. It is designed so that it can be swung up and down.

By the operation of the parallel link 19, the first hoisting arm 13 hoists in a range from a substantially upright position as shown in FIG. 6 to a position parallel to the swivel arm 11 as shown in FIG. A position at which the second undulating arm 14 is hung down from the horizontal position of FIG. 6 at a right angle to the first undulating arm 13 of FIG. 7 along the front surface of the traveling carriage 1 by the operation of the parallel link 19. The first and second undulating arms 13 and 14 are compactly folded along the upper surface and the front surface of the traveling carriage 1 when the washing work is not performed.

When cleaning the leading portion of the Shinkansen, the traveling carriage 1 is stopped at an appropriate position in front of the Shinkansen as shown in FIGS. 5 and 6, and the first hoisting arm 13 is raised and the second raising arm is raised. The protrusive arm 14 is extended, the nozzle 15 is brought close to the leading portion, and the chemical solution and the high-pressure water are alternately sprayed. When the portion to be cleaned becomes left and right, the swivel arm 11 is swung around the first rotary shaft 16 and the swivel base 12 is swung around the second rotary shaft 17, so that the first and second undulating arms 13 and 14 are moved. It can be moved left and right in parallel. Therefore, by controlling the rotation of the swivel arm 11 and the swivel base 12, even if there are obstacles on the left and right of the Shinkansen, the nozzle 15 can be moved so as not to hit them. After washing, the swivel arm 11 is directed to the rear of the traveling carriage 1, the second undulating arm 14 is contracted, and the first undulating arm 13 is tilted so as to be parallel to the swivel arm 11, and then the second undulating arm 11 is lifted. The arm 14 is hung along the front surface of the traveling carriage 1. As a result, the arms are compactly folded, the carriage 1 can be moved safely, and the carriage 1 can be stored in a narrow space.
