Description

  The present invention relates to a road maintenance vehicle used for special purposes, and more particularly to a road maintenance vehicle for supplying electric energy in a disaster occurrence place or the like.

  2. Description of the Related Art Conventionally, for example, a road maintenance work vehicle for antifreezing agent spraying (referred to as an antifreezing agent spraying vehicle) is a hydraulic pump in a power take-off port PTO (POWER TAKE-OFF) attached to a traveling engine mission. The hydraulic motor for operating the actuator for spraying the antifreezing agent is driven by the pressure oil discharged from the pump. Therefore, since the conventional antifreezing agent spraying vehicle is a fixed power transmission system, it is a vehicle that can perform only predetermined road maintenance work. For this reason, the vehicle was only secured and managed in a parking space except during the winter when the work was completed. In addition, there are various vehicles such as snow plow vehicles, mobile road sign vehicles, asphalt finishers, surface treatment vehicles, and the like as road maintenance work vehicles whose usage purposes are limited. Here, the road maintenance vehicle broadly refers to a vehicle used for road construction, road maintenance and the like. Such a road maintenance vehicle has a limited use, and even if it is used at the time of snowfall or limited use, it will be suspended until the next use time when the snowfall time or road construction is completed. Therefore, there is a problem that the operation rate is poor and the maintenance cost increases.

  Under the above circumstances, Patent Documents 1, 2, and 3 disclose road maintenance vehicles that are used for multiple purposes. Patent document 1 is a snow plow vehicle and discloses a road maintenance vehicle that can operate as a watering vehicle except in winter. Patent Document 2 discloses a mobile road maintenance vehicle that is an antifreezing agent spray vehicle that can operate as a water spray vehicle or a water supply vehicle except in winter. Patent Document 3 discloses a road maintenance vehicle that can operate as a sludge collection vehicle or a dust collection vehicle when it is not used for its original purpose, and is a snow plow vehicle, an antifreeze spray vehicle, or a mobile road sign vehicle. . As described above, the road maintenance vehicles described in Patent Documents 1 to 3 can be used for purposes other than the intended use.

  Now, when a disaster occurs, in the disaster occurrence area, the power wiring is cut off, and there is a case where the power supply until the cut-off wiring becomes widespread becomes a problem. In the past, stationary power generators were transported and installed to the site by trucks, etc., making it possible to supply power in disaster-affected areas, but this was a response lacking in mobility. Although there exists a self-propelled vehicle provided with a power generator as in Patent Document 4, it is not a vehicle for supplying electric power in the event of a disaster.

  Although it is possible to deploy a stationary engine generator in advance to deal with disasters, it is difficult to know when and where disasters occur, so the operating rate is extremely poor and the maintenance burden increases. Yes, it is not realistic to deploy such a generator.

  Then, an object of this invention is to provide the road maintenance vehicle which can go to a disaster area etc. and can supply emergency power when it is not used.

  In order to solve the above problems, the present invention has the following features. The present invention includes a road maintenance unit having a function necessary for road maintenance, a travel engine used for traveling the vehicle, and an emergency generator that generates power using power extracted from the travel engine. It is a road maintenance vehicle.

  Preferably, a rectifier for rectifying the electric power obtained by the emergency generator may be further provided.

  Preferably, the traveling engine includes a power take-off attached to the mission, and the emergency generator generates electric power with rotational power obtained from the power take-off.

  Preferably, further, a first transmission means for transmitting the rotational power from the power take-off, and a second transmission means for transmitting the rotational power for transmitting the first transmission means to the emergency generator It is good to have.

  Preferably, a hydraulic pump that is driven by the rotational power transmitted from the first transmission means is further provided, and the second transmission means may be a pulley and a V belt provided in the first transmission means.

  ADVANTAGE OF THE INVENTION According to this invention, it can generate electric power using the motive power taken out from the driving engine of the road maintenance vehicle. Therefore, it is possible to go to disaster areas and use the road maintenance vehicle as an emergency power source. Since road maintenance vehicles have limited uses, they can freely visit disaster areas while not in use. Therefore, it leads to effective use of road maintenance vehicles. Since road maintenance vehicles generally have high horsepower, they easily reach disaster areas. If such a road maintenance vehicle is utilized as an emergency power supply source, there is no need to install a stationary generator or the like for emergency use, and the cost burden for preparing for a disaster is reduced.

  If a rectifier is provided in the emergency generator, it is possible to supply electric power suitable for home use and factory use.

  By taking out the rotational power supplied to the emergency generator from the power take-off (PTO), power can be generated with a simple structure, which is suitable for practical use. For example, by using a mechanism called first and second transmission means, practical use becomes possible. Furthermore, if the second transmission means is constituted by a pulley and a V-belt, the transmission of rotational power is facilitated. In addition, by using a pulley and a V-belt as the second transmission means, a hydraulic pump can be installed at the end of the power take-off, and the power obtained from the hydraulic pump can be used for other purposes. it can.

  In some cases, the emergency generator can be used as electric power for driving various drive units of the road maintenance vehicle. For example, the electric power can be used to rotate the rotating disk of the antifreezing agent spraying vehicle, or the electric power can be used to turn on the marker lamp of the mobile marker car.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

As a result, a road maintenance vehicle that can be used as an emergency power source is provided in the event of a disaster.

  In particular, the road maintenance vehicle running engine 4 is often a high horsepower engine, and if such a running engine is used to generate power by the emergency generator 11, high power can be output. It can be expected to be used effectively as an emergency power source in the event of a disaster. Since road maintenance vehicles are not used except during winter and during construction, they can go to the disaster area and supply power during a disaster, and can be used effectively. Road maintenance vehicles can be self-propelled, so they can be moved to the required place when needed, regardless of the location, like a stationary generator, which is extremely effective as an emergency power source. Thought to work.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The present invention can be industrially used as a road maintenance vehicle.
