Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle front and rear surface cleaning device. Conventionally, various types of devices for automatically cleaning railway vehicles such as railroads have been proposed. Cleaning of a structure capable of cleaning not only the side surface of the vehicle but also the front or rear surface of the vehicle (hereinafter referred to as front and rear surfaces) Devices are also known.
In a device for cleaning the front and rear surfaces of a vehicle, a cleaning device is usually installed on both sides of a vehicle rail, and a cleaning brush is swung horizontally to clean the front and rear surfaces of the vehicle.

[0002]

However, in the above-mentioned conventional structure, a structure is required to stand the cleaning device on the side of the rail, and it is necessary to provide such a structure on both sides of the rail. is there. Also, since the brush swings horizontally, it is necessary to have a structurally strong one,
There is a drawback that the device becomes large and the cost becomes high. Further, in the case of a subway or the like, a third rail for electric power is laid on the floor surface, which makes it difficult to install the front and rear surface cleaning device having the conventional structure, and there is a problem that there is a risk of leakage or short circuit. there were. The present invention aims to solve the above-mentioned problems of the prior art.

[0003]

In order to achieve the above object, a vehicle front and rear surface cleaning apparatus of the present invention is provided with a traveling rail provided above the vehicle, a traveling rail provided so as to be able to travel on the traveling rail, and a traveling rail provided below the traveling rail. It is characterized by comprising a rotatable arm and a cleaning brush which runs on the arm. Further, in the invention of claim 2, the third rail for the power source is provided in the lower portion,
A vehicle front and rear surface cleaning device installed on a vehicle traveling path having a ceiling portion, the pair of traveling rails provided on the ceiling portion, provided so as to be able to travel on the traveling rails, and rotatable downward. , A pair of arms that can take a storage position close to the traveling rail and an operating position that is hung downward, and both ends of the shaft are supported by the pair of arms, and the cleaning is movable on the arms. Brush and the arm for cleaning, the arm is lowered downward, the arm is moved on the traveling rail to adjust the horizontal position of the cleaning brush, and the cleaning brush is moved on the arm to move the front and rear surfaces of the vehicle. It is characterized in that washing is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a front and rear surface cleaning device for a subway vehicle will be described below with reference to the drawings. In FIG. 1, a vehicle Z runs on a road surface Y in a tunnel, stops at a predetermined position, and receives the cleaning of the front and rear surfaces α. On the ceiling X of the tunnel, a traveling rail 1 having a predetermined length is provided at a predetermined position, and an arm 2 is rotatably suspended from the traveling rail 1. Running rail 1
2 are provided as shown in FIG. 2, on which the traveling carriage 10 is suspended so that it can travel.

The traveling vehicle 10 is provided with a traveling motor 11 so that it can travel on the traveling rail 1. The traveling vehicle 10 is provided with a rotating shaft 20 that supports the bases of the pair of arms 2.
Is configured to rotate about a rotation shaft 20. An arm motor 13 is provided on the traveling vehicle 10,
By winding or lowering the wire 14, the arm 2 can be lowered to the operating position as shown in FIGS. 1 and 2, or can be stored in the storage position near the traveling rail 1 as shown in FIGS. 3 and 4. It has become. A proximity switch 12 is provided on the traveling carriage 10, and a proximity switch operating piece 22 is provided on the arm 2 corresponding to the proximity switch 12, so that the arm 2 can be stored at a predetermined position.

A cleaning brush 3 is provided between the pair of arms 2, 2.
Both ends of the shaft are supported. In this embodiment, as shown in FIG. 2, brush frames 30 are provided at both ends, and the shaft of the cleaning brush 3 is mounted between the brush frames 30. Brush frame 30
Is movable on the arm 2, and is connected to the endless chain 32 in this embodiment, and is configured to move on the arm 2 by driving the brush lifting motor 21. A brush rotation motor 31 is further provided on the brush frame 30, and the cleaning brush 3 is rotated by the drive of the brush rotation motor 31 so that the front and rear surface α of the vehicle Z or the roof β in addition to this is cleaned. It has become.

With the above construction, when the cleaning is not performed, the arm 2 is raised upward as shown in FIGS. In this state, the traveling of the vehicle Z is not affected at all. When cleaning the front and rear surfaces α of the vehicle Z,
The wire 14 is loosened by the arm motor 13, the arm 2 is lowered to the operating position shown in FIG. 1 by its own weight, and the brush rotation motor 31 is driven to rotate the cleaning brush 3.
Then, by moving the traveling carriage 10 on the traveling rail 1 by the traveling motor 11, the cleaning brush 3 is moved in the horizontal direction, and while the contact state with the front and rear surface α is adjusted, the brush elevating motor 21 is used. The brush frame 30 is moved in the arm 2 to move the cleaning brush 3 up and down to clean the entire front and rear surface α. With this configuration, the cleaning brush 3 can be moved along the shape of the front and rear surfaces α, and effective cleaning can be realized. If necessary, the arm 2 can be lifted a little and the cleaning brush 3 can be brought into contact with the roof β to clean the roof β of the vehicle Z.

[0008]

As described above, the front / rear surface cleaning device of the present invention does not need to be provided with equipment on the side of the vehicle rail. Therefore, even in a place such as a subway where the third rail is provided, there is no danger. Can be installed. Further, since it is not necessary to stand the equipment and to swing the cleaning brush in the horizontal direction, the apparatus can be downsized and the cost can be reduced. Further, since the cleaning brush can be moved in the vertical direction and the horizontal direction, it is possible to clean along the shape of the front and rear surfaces of the vehicle, and the cleaning efficiency is improved. Further, when installed on the ceiling of a subway or the like, there are effects such as further simplification of the device and cost reduction.
