Grooves (41) are provided between the rails (71) (71) for walking and pulling various cables along the rails.

A rail (71) is used for an operator to move in the mine.
Walk in the groove (41) between (71) or use the carriage (1). The trolley (1) is equipped with a human-powered type in which an operator riding on the trolley scratches his / her hand on an appropriate protruding portion of a tunnel segment or kicks the floor surface with his / her foot, and a battery and a drive motor. There is a self-propelled type.

[0004] Walking in a narrow minehole with a leaning forward posture is problematic in terms of safety and workability, and physical fatigue is significant. Even if the mine is wide, the same is true for long distances, and in particular, the moving time is long and inefficient. On the other hand, when using a carriage, the carriage (2) must be evacuated from the rails (71) (71) when the carriage group (82) passes. Since the trolley of the human power traveling type has only the weight of the frame and the wheels, it is lightweight and not bulky, and can be easily made to stand on another beach.

On the other hand, the self-propelled trolley leans against the side wall of the mine (4) and stands by to the side (3).
Runs out of the carriage group (82) and gets in the way,
Since the weight of the battery is heavy, the center of gravity of the leaning carriage is the rail (71), which is not stable. Further, the battery is turned sideways, which causes problems such as leakage of the battery fluid.

Therefore, one of the applicants of the present application is

In a passenger dolly comprising a frame (11) equipped with (17), a motor (2) for driving wheels and a battery (3),
(3) is rotatably supported in a plane along the longitudinal direction of the frame (11).

[0010]

[Operation and effect] When the passenger truck (1) is evacuated from the rails (71) (71), the passenger truck (1) is lifted and the underground (4)
Lean against the side wall of the. The battery (3) is
Since the battery (3) is rotatably supported in the plane along the longitudinal direction of the frame (11), the battery (3) is borne by its own weight.
Face the vertical direction regardless of the leaning angle of 1). Therefore, if the battery (3) is fixed to the lower part of the frame (11), when the passenger truck (1) leans into the mine, the carriages (82) traveling on the rails (71) (71) can travel. Battery (3) on the transition path
Even in the case where it gets out of the way and is an obstacle, due to the configuration of the present application,
It is possible to prevent the battery from leaking out to the transfer path of the carriage group (82). Further, the battery (3) always faces the vertical direction regardless of the leaning angle of the passenger trolley (1), so that the center of gravity of the passenger trolley (1) including the battery is displaced inward, and the passenger trolley (1) is stable. ) Can be leaned against. Furthermore,
Even when the operator folds the passenger cart (1) and carries it,
Since the center of gravity of (1) is displaced inward, it is easy to carry.
In addition, the battery (3) will not be sideways,
