Description

  The present invention relates to a road maintenance vehicle in which road maintenance vehicles such as anti-freezing agent spray vehicles, snow plow vehicles, and mobile road sign vehicles used only in winter and limited conditions can be used as vehicles for collecting sludge. It is.

  Conventionally, as a road maintenance vehicle used in winter, a spray vehicle for spraying an antifreezing agent on a road and a snow plow vehicle for removing snow from the road are widely known. Also, existing mobile road sign cars are limited to use only as road construction support vehicles. The power is only used for the illumination of the marker lamp, and it may be insufficient as a power source for other actuators, and the frequency of use of this vehicle is also limited.

  As described in Patent Document 1, the antifreezing agent spraying vehicle is configured to carry an antifreezing agent storage hopper installed in the main body of the spraying vehicle and a reverse antifreezing agent supplied from the antifreezing agent storage hopper. And a spraying device for spraying the antifreezing agent delivered from the transport means, and as is well known, the snow plow is equipped with a snow plow at the front end of the vehicle body, It is configured to be activated by a pump that is operated by a hydraulic unit installed on the loading platform. In recent years, there has been an increasing demand for improving the frequency of use of the vehicle. As an example, it is being considered to mount a generator in a snow plow vehicle for lighting a signage device, remove the plow device only in summer, and use it as a mobile road signage vehicle.

  On the other hand, as a vehicle for collecting sludge staying in a side groove of a road, for example, as described in Patent Document 2, a sealed tank equipped with an open / close plate is mounted on the vehicle, Connect the mud pipe connecting the mud hose, put the tip of the mud hose into a side groove, etc., and make the tank negative pressure with a blower, suck the sludge from the mud hose through the mud pipe A vehicle configured to be housed in a sealed tank is known.

  However, even if the antifreezing agent spray vehicle, snow plow vehicle or mobile road sign car is used during snowfall or limited use, it will be suspended until the next use time when the snowfall time or road construction is over. It will be. Therefore, there is a problem that the operation rate is poor and the maintenance cost increases. Further, the above-mentioned sludge collection vehicle has a short use period and is also a sludge collection-only vehicle equipped with a large-scale collection device, which is extremely expensive and uneconomical. If the snow plow car is used as a sign car, the operating rate is improved, but it is still insufficient. Mobile road sign vehicles are also inadequate for similar reasons. Japanese Patent Laid-Open No. 2005-205069 has been proposed as the above solution. However, the purchase price including each device becomes very expensive, and the installation cost of the building for securing the location of each device and not being exposed to wind and rain The total cost including up to now has imposed a heavy burden on the maintenance company. Furthermore, it is necessary to operate each device regularly even if there is no opportunity to use it, and it is necessary to always operate each device constituting the device smoothly, and the labor cost for that is also a burden on the maintenance company.

  The present invention has been made in view of such problems, and its object is to change the basic structure of road maintenance vehicles such as anti-freezing agent spray vehicles, snow plow vehicles and mobile road sign vehicles.
