【発明が解決しようとする課題】しかし、前者は軌道用鉄輪を作業車に備え、車輪にかえ鉄輪を軌道上に載せる構造であり、後者は作業車に鉄輪を設けず、車輪と軌道の間に台車を介在させるために、前後のアウトリガー装置を用いて車両を持上げる構造である。したがって前者は鉄輪が回転しなくなった場合の緊急脱出の対策がない。また、後者は車両の前後に予め設けたアウトリガー装置が、車両の前後にあるので、大型作業車には常時備えていてもスペース的に問題ないが、小型・中型の作業車には、前後のアウトリガー装置は使用しないとき邪魔になる。さらに、取付スペースも少ない。また装備するアウトリガー装置は作業車の総重量を増大させ、装備する数が増えれば当然、それだけ総重量も増大する。この結果、特に小型・中型では重量の法的制限を越える可能性もある。 0003
However, the former has a structure in which an iron wheel for a track is provided on a work vehicle and the iron wheel is placed on the track instead of the wheel, and the latter is a structure in which the iron wheel is not provided on the work vehicle and is between the wheel and the track. The structure is such that the front and rear outrigger devices are used to lift the vehicle in order to intervene the dolly. Therefore, the former has no emergency escape measures when the iron wheel stops rotating. In the latter case, outrigger devices provided in advance on the front and rear of the vehicle are located on the front and rear of the vehicle, so there is no problem in terms of space even if they are always provided for large work vehicles, but for small and medium-sized work vehicles, the front and rear The outrigger device gets in the way when not in use. In addition, the mounting space is small. In addition, the outrigger device to be equipped increases the total weight of the work vehicle, and naturally, the total weight increases as the number of equipped outrigger devices increases. As a result, the legal limit on weight may be exceeded, especially for small and medium sized vehicles.

【発明の効果】この発明は、作業車の鉄輪が作動しないとき、空・積荷状態に関わらず、アウトリガー装置及びレールキャッチを利用することにより、車体を前方側または後方側のみを持ち上げ支持することができる。したがって、鉄輪及びタイヤ車輪が鉄道用レールから浮き上がった状態となったとき、軌道用台車を車体の下部に進入させて作業車を移動させるため、迅速に、かつ効率よく安全に回復・移動させることができる。また車体の前方側または後方側のみを持ち上げ他方は地面に接しているため、アウトリガー装置が持ち上げる重量は、作業車全体を持ち上げる場合に比べ軽くなる。このため装備するアウトリガー装置としては、より小型で軽量なものが使える。 [0028]
According to the present invention, when the iron wheel of a work vehicle does not operate, the vehicle body is lifted and supported only on the front side or the rear side by using an outrigger device and a rail catch regardless of whether the vehicle is empty or loaded. Can be done. Therefore, when the iron wheels and tire wheels are lifted from the rails for railroads, the track bogie is moved to the lower part of the car body to move the work vehicle, so that it can be recovered and moved quickly, efficiently and safely. Can be done. Further, since only the front side or the rear side of the vehicle body is lifted and the other side is in contact with the ground, the weight lifted by the outrigger device is lighter than that when the entire work vehicle is lifted. For this reason, smaller and lighter outrigger devices can be used.
