Title: Transport vehicle and steering control program for transport vehicle
Inventor: MATSUNAGA TAKASHI
IPC: B61B13/00
Filed: 2019-02-28
Abstract: To provide a transport vehicle that can stably travel even on a curved road, and a steering control program for the transport vehicle.SOLUTION: A distance Lip of virtual origins Cf and Cr with respect to a guide sensor 4 is set shorter when a traveling path is curved than when it is linear. As the distance Lip is longer, a steering angle θv becomes smaller even if deviation amounts df and dr are the same, so that the vehicle can travel stably on a straight traveling path. On the other hand, the shorter the distance Lip is, the larger angles θf and θr formed for calculating a turning center C with respect to the deviation amounts df and dr are, and the smaller a turning radius from the turning center C to each rotation axis 3c is. As a result, even if the deviation amounts df and dr are the same, the steering angle θv becomes large, so that a followability on a curved traveling path is improved. Therefore, stable running can be realized even on a curved running road.SELECTED DRAWING: Figure 3

Abstract: To provide a tank capable of preventing careless leakage of water dew-condensed on the surface of an inner tank to the outside of the tank, and a tank container.SOLUTION: Water dew-condensed on the surface of an inner tank 3a and flowing-in therefrom is collected in a water collector 4 and a connection dish 5, and further flows into a drain pipe 6 and a drain hose 7 connected to the water collector and the connection dish. When a drain valve 8 is a cutoff state, dew condensation stays in the water collector 4, the connection dish 5, the drain pipe 6, and the drain hose 7. On the other hand, when the drain valve 8 is operated to drain water, the dew condensation left in the water collector 4, the connection dish 5, the drain pipe 6, and the drain hose 7 are discharged from the drain valve 8, in other words, from a prescribed place of a tank container 1. Thus, erroneous recognition of leakage of a loaded article can be prevented by preventing careless leakage of the water dew-condensed on the surface of the inner tank 3a to the outside of a tank 3.SELECTED DRAWING: Figure 5
