Abstract

PROBLEM TO BE SOLVED: To avoid the generation of overwhelming feeling due to head lights of a cleaning vehicle by directing a cleaning brush unit to one of right and left directions for cleaning of a tunnel wall surface, and thereafter, directing the brush unit to the other side for cleaning so as to avoid the traveling opposite to general vehicles. SOLUTION: A first cleaning brush unit is turned to a right side of the progressing direction of a tunnel cleaning vehicle and a second cleaning brush unit is turned to a left side of the progressing direction thereof. Continuously, a third cleaning brush unit 3 is turned to a left side of the, progressing direction of the cleaning vehicle so that the third cleaning brush unit 3 abuts on a side wall, of a tunnel in an upper part of a travelling lane. Continuously, the cleaning vehicle is made to run in the traveling direction so as to clean a left side wall of an up lane. After the left side wall surface of a down lane is cleaned, direction of the cleaning brush unit is changed so as to clean the right side wall surface of the up lane and the right side wall surface of the down lane. With this structure, the tunnel cleaning vehicle always travels in the same direction with general vehicles, and the generation of overwhelming feeling to a driver of a general vehicle due to head lights of the tunnel cleaning vehicle can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a cleaning brush unit capable of changing the direction of the wall surface of a tunnel dedicated to an up lane and a tunnel dedicated to a down lane extending in parallel to each other to the left or right in the traveling direction. The present invention relates to a cleaning method of a tunnel cleaning vehicle for cleaning with a cleaning vehicle.

[0002]

2. Description of the Related Art A tunnel cleaning vehicle equipped with a cleaning brush device is already known as described in Japanese Patent Application Laid-Open No. 60-98100.

[0003] This tunnel cleaning vehicle is provided with a cleaning brush at the tip of an arm supported on the vehicle body to be able to turn left and right.
The cleaning brush is brought into contact with the wall of the tunnel for cleaning.

[0004]

However, in the above-mentioned prior art, since the lower end of the cleaning brush is located below the coupler of the tunnel cleaning vehicle, the cleaning brush is moved by the interference with the coupling of the tunnel cleaning vehicle. There is a problem that it cannot be moved to the right and left opposite sides, so that only one of the left and right tunnel wall surfaces in the traveling direction can be cleaned.

Therefore, when cleaning the left and right tunnel wall surfaces with such a tunnel cleaning vehicle, it is possible to prevent the tunnel cleaning vehicle from facing a general vehicle running in the tunnel when cleaning either the left or right tunnel wall surface. Therefore, a problem arises in that the headlight of the tunnel cleaning vehicle gives the driver of the vehicle a feeling of intimidation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has right and left tunnel wall surfaces of a first lane in which a vehicle travels in a first direction and a second direction opposite to the first direction. It is an object of the present invention to enable a tunnel cleaning vehicle to clean the left and right tunnel wall surfaces of the second lane traveling in the same direction without facing the vehicle.

[0007]

Means for Solving the Problems In order to achieve the above object, an invention according to claim 1 is a cleaning car capable of changing the direction of a cleaning brush unit to the left and right in a traveling direction. A tunnel cleaning vehicle for cleaning left and right tunnel wall surfaces of a first lane traveling in a first direction and right and left tunnel wall surfaces of a second lane traveling in a second direction opposite to the first direction. A cleaning step, in which a cleaning vehicle with a cleaning brush unit directed to one of the left and right sides of the vehicle moves in a first direction in a first direction to clean one of left and right tunnel wall surfaces of the first lane; The cleaning truck with the unit turned to one side is traveling in the second lane in the second direction while
A second step of cleaning one of the left and right tunnel walls of the lane;
A third step of cleaning the tunnel wall surface on the left or right side of the first lane while the cleaning vehicle with the cleaning brush unit directed to the other side is traveling in the first lane in the first direction; And a fourth step of cleaning the other of the left and right tunnel walls of the second lane while the cleaning vehicle travels in the second lane in the second direction.

[0008] According to the above configuration, the cleaning brush unit of the cleaning vehicle is directed to the left and right sides to clean the left and right tunnel walls of the first lane and the left and right tunnel walls of the second lane. Since the unit is turned to the other side and the other left and right tunnel wall surfaces of the first lane and the other left and right tunnel wall surface of the second lane are cleaned, the cleaning vehicle may face a vehicle traveling in the first lane and the second lane. As a result, the headlights of the cleaning vehicle do not intimidate the driver of the vehicle.

According to a second aspect of the present invention, there is provided a cleaning vehicle capable of changing the direction of the cleaning brush unit to the left or right in the traveling direction, and the right and left of the first lane in which the vehicle travels in the first direction. A cleaning method for a tunnel cleaning vehicle for cleaning a tunnel wall surface and left and right tunnel wall surfaces of a second lane in which a vehicle travels in a second direction opposite to the first direction, wherein the cleaning brush unit is disposed on one of left and right sides. A first step of cleaning the left and right tunnel wall surfaces of the first lane while the cleaning vehicle traveling in the first lane in the first direction is in the first lane; A second step of cleaning the other left and right tunnel wall surface of the second lane while traveling in the second direction, and a cleaning car with the cleaning brush unit directed to the other side, traveling the first lane in the first direction. Tunnel on the other side of the first lane A third step of cleaning the wall surface; and a fourth step of cleaning the left and right tunnel wall surfaces of the second lane while the cleaning vehicle with the cleaning brush unit directed to the left or right travels in the second lane in the second direction. It is characterized by having.

According to the above construction, the cleaning brush unit of the cleaning vehicle is directed to one of the left and right sides to clean the left and right tunnel wall surfaces of the first lane, and then the cleaning brush unit of the cleaning vehicle is directed to the other side of the second lane. Of the other left and right tunnel walls and the left and right tunnel walls of the first lane, and then turn the cleaning brush unit of the cleaning car to the left or right side of the second lane.
Cleans the left and right tunnel walls of the lane so that the cleaning vehicle does not face vehicles traveling in the first and second lanes, and the headlights of the cleaning vehicle do not intimidate the driver of the vehicle Is done.
