Guide rail type vehicle
View Patent ↗A guide rail type vehicle is provided with a guide wheel that comes into rolling contact with a guide rail, a switching wheel that is comes into rolling contact with a switching rail installed at a switching location of the guide rail, a wheel axle in which the guide wheel is connected to the top end and the switching wheel is connected to the bottom end, a support receiver of which the height dimension is set to be smaller than the corresponding length dimension of the wheel axle and which supports the wheel axle, and adjustment device which adjusts the sizes of a gap of the guide wheel side and a gap of the switching wheel side, which are accessed from a direction orthogonal to the axial direction of the wheel axle, and are therefore capable of adjusting the height of the guide wheel and the switching wheel.
1. A guide rail vehicle for running along a guide rail, the guide rail vehicle comprising:
a guide wheel which comes into rolling contact with the guide rail;
a switching wheel which comes into rolling contact with a switching rail installed at a switching location of the guide rail;
a wheel axle of which the guide wheel is fixed on one end thereof and the switching wheel is fixed on another end thereof;
a support receiver of which a dimension in a height direction is smaller than a corresponding length dimension of the wheel axle and which supports the wheel axle; and
an adjustment device which is capable of adjusting a size of a gap between the support receiver and the guide wheel and a gap between the support receiver and the switching wheel while both the guide wheel and the switching wheel remain fixed on the respective ends of the wheel axle without changing their positions along the length of the wheel axle,
wherein the adjustment device includes a plurality of height adjustment shims, the wheel axle being inserted into the plurality of height adjustment shims,
wherein the plurality of height adjustment shims are slidably provided between the guide wheel and the switching wheel, and
wherein the plurality of height adjustment shims are mounted at one or both of the gap between the support receiver and the guide wheel and the gap between the support receiver and the switching wheel.
2. The guide rail vehicle according to claim 1 ,
wherein the wheel axle is detachably mounted on the support receiver, and
wherein the plurality of height adjustment shims have an annular shape.
3. The guide rail vehicle according to claim 1 , wherein each of the height adjustment shims is a single piece extending completely around the wheel axle.
4. A guide rail vehicle for running along a guide rail, the guide rail vehicle comprising:
a guide wheel which comes into rolling contact with the guide rail;
a switching wheel which comes into rolling contact with a switching rail installed at a switching location of the guide rail;
a wheel axle of which the guide wheel is connected to one end thereof and the switching wheel is connected to another end thereof;
a support receiver of which a dimension in a height direction is smaller than a corresponding length dimension of the wheel axle and which supports the wheel axle; and
an adjustment device which is capable of adjusting a size of a gap between the support receiver and the guide wheel and a gap between the support receiver and the switching wheel,
wherein the support receiver comprises:
a support receiving body having a concave portion to which the wheel axle is able to be inserted from a side of the support receiving body, and having a dimension in the height direction that is shorter than the corresponding length dimension of the wheel axle by a height adjustment allowance; and
a lid portion, which is joined to the support receiving body with a bolt and covers the concave portion,
wherein the adjustment device has teeth provided between contacting surfaces of the support receiving body and the lid portion with a predetermined gap in the height direction, the teeth provided on the support receiving body and the lid portion being engaged to each other, and
wherein a long hole is formed to the lid portion, the long hole extending in the height direction in such a way that the bolt is able to be inserted through the long hole.
