Abstract

A cleaning vehicle provided with driving wheels for traveling on a rail having a trench-shaped driving space provided on the floor for cleaning the rail, wherein a vehicle body is provided with an air drawer formed by providing a filter to an air outlet hole, a tip end portion of a drawing hose connected to the air drawer is provided with an air drawing member having an opening on the bottom of the rail, an air outlet is formed on the wall of a box-shaped body covering the entire air drawer, and an air cleaning unit is provided to the air outlet.

Claims

1. A cleaning vehicle for cleaning a guide member having a trench-shaped driving space provided on the floor, comprising:

a vehicle body;

wheels provided to said vehicle body, for traveling along the guide member;

a support axis body interconnecting said vehicle body and one of said wheels and defining a hollow portion extending between said vehicle body and said one wheel;

an air drawer provided to said vehicle body and provided with a dust removal member at its air exhausting portion;

an air drawing tube extending between said air drawer and said support axis body;

an air drawing member provided at an end portion of said support axis body and having an opening adjacent to the guide member and being fluidly interconnected with said dust removal member via said hollow portion of said support axis body and said air drawing tube;

a box-shaped body covering said air drawer and having an air outlet on an upper wall; and

an air cleaning unit provided on the upper wall of said box-shaped body and configured to clean air exhausted from said air outlet.

2. The cleaning vehicle as set forth in claim 1, wherein the opening of said air drawing member has a rectangular section being long in the width direction of the guide member when cut horizontally, and the axial section has a trapezoidal shape, by which the front and rear walls become apart at the lower part.

3. The cleaning vehicle as set forth in claim 2, wherein the front and rear rim portions of the opening of said air drawing member are provided with a brush member for preventing dusts accumulated on the bottom of the guide member from moving to outside of the opening.

4. The cleaning vehicle as set forth in claim 1, wherein the front and rear rim portions of the opening of said air drawing member are provided with a brush member for preventing dusts accumulated on the bottom of the guide member from moving to outside of the opening.

5. The cleaning vehicle as set forth in claim 4, wherein a density of said brush member provided at said front rim portion is less than a density of said brush member provided at said rear rim portion.

6. The cleaning vehicle as set forth in claim 1, wherein said air drawing member has front, rear, right, and left rim portions for defining said opening, and wherein each of said rim portions is provided with a brush member.

7. The cleaning vehicle as set forth in claim 6, wherein a density of said brush member provided at said front rim portion is less than a density of said brush member provided at said rear rim portion.
