Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line cleaning unit provided on a traveling vehicle to constitute a line cleaning vehicle, and a line cleaning vehicle provided with the unit.

[0002]

2. Description of the Related Art White lines and yellow lines (hereinafter referred to as lines) drawn on a road surface of a vehicle are stained with the traffic of the vehicle or faded by the sunlight, so that the lines may be discolored by maintenance. Then, the line cleaning vehicle is driven to clean the line surface with a line cleaning brush provided in the line cleaning vehicle.

[0003] This conventional line cleaning vehicle is provided with a line cleaning brush, which is driven and rotated by a hydraulic or electric driving means, on a traveling vehicle. Because the traveling speed is slow, line cleaning is performed after restricting the traffic on the cleaning lane.

[0004]

However, this line cleaning vehicle is a very expensive line cleaning vehicle equipped with a hydraulic or electric drive means, and the carrier is provided with a hydraulic or other drive means. The vehicle cannot be diverted for transporting materials, etc., and the running speed during line cleaning is slow, so it is necessary to restrict the traffic in the cleaning lane for a long time. In many cases, it caused traffic congestion on the road.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is possible to carry out line cleaning at a high speed, and furthermore, a driving means for rotating and raising / lowering a line cleaning brush is provided. Even if it is a vehicle other than the original work purpose, such as a signboard vehicle with a display signboard to restrict the entry of the vehicle into the construction lane or a material transport truck, it is not necessary separately, It is another object of the present invention to provide a line cleaning unit that can be configured as a line cleaning vehicle at low cost, and a line cleaning vehicle including the unit.

[0006]

In other words, the line cleaning unit according to the present invention, which constitutes a line cleaning vehicle connected to the traveling vehicle, is directed rearward in the traveling direction with respect to the body frame of the traveling vehicle. A grounding wheel and a shock absorber for buffering the floating of the grounding wheel are provided on a wheel frame that is connected to be able to swing up and down, and a brush frame that can swing up and down toward the rear in the traveling direction is provided on the wheel frame. And, on the brush frame, a driven wheel that uses a grounded wheel as a rotational drive source, and a line cleaning brush that is connected to the driven wheel and cleans a line on a road surface with rotation, further provided. Line cleaning brush lift control means,
It comprises a manually operated wheel frame lifting / lowering means, a wheel frame lifting / holding means, and a frame connecting means for integrating the brush frame with the wheel frame while the wheel frame is being lifted.

[0007] The line cleaning unit according to the present invention is constructed by setting the line cleaning unit having such a configuration on a body frame of a signboard vehicle or the like. In this manner, the line cleaning unit is mounted on the traveling vehicle. With the wheel set lowered, the wheel frame is lowered by manual operation to bring the grounding wheels and the line cleaning brush into contact with the road surface line, and when the vehicle is running, the line cleaning brush moves in the direction opposite to the traveling direction of the vehicle. By rotating at a high speed, the road surface line is cleaned.

That is, when the vehicle travels, the grounding wheel rotates at the vehicle traveling speed, and this rotational power is transmitted to the line cleaning brush via the driven wheel, and the driven wheel is structured to contact the ground. Since the diameter becomes smaller than the wheels, the road cleaning brush rotates at a high speed in a direction opposite to the traveling direction of the vehicle, thereby cleaning the road surface line. Since it can be performed by high-speed running of the vehicle, it is not necessary to regulate the traffic on the cleaning lane accompanied by traffic congestion on the road.

In addition, since the wheel frame is provided with a shock absorber and further provided with means for controlling the lifting of the brush frame, the grounding wheel bounces due to the unevenness of the road surface, and the line cleaning brush tends to rise. However, it does not bounce slightly in time and does not bounce much, so that the road line can be cleaned stably.

[0010] By lifting the wheel frame, integrating the brush frame during the lifting, and maintaining the lifting posture of the wheel frame, the vehicle equipped with the above line cleaning unit is a simple general-purpose vehicle. Since the vehicle is a traveling vehicle, the vehicle can be used for original material transportation.

The wheel frame is pivotally attached to a base frame rotatably in the left-right direction with respect to a body frame of the traveling vehicle, and frame fixing means is provided. If the line cleaning brush is configured to be repositionable and fixable in the left and right direction, the line cleaning brush can be stored in the vehicle width or extended outside the vehicle width, and the wheel frame can be placed right next to the vehicle body. If it protrudes, for example, replacement of the grounding wheel and other maintenance can be performed easily.
