Claims

[Scope of utility model registration request]

At the required height position on the rear of each self-propelled bogie that runs at high speed on straight sections and medium speed on curved sections along the track,
A strip-shaped reflector extending in the width direction of the self-propelled vehicle is fixed so as to be perpendicular to the traveling direction of the self-propelled vehicle, and light is emitted in the axial direction at the same height as the reflector on the front surface of each self-propelled vehicle. A coaxial reflective photoelectric switch that detects reflected light returning from above is used for low-speed commands on straight sections of the track to give low-speed commands to self-propelled bogies traveling at high speeds on straight sections. Attach it facing forward so that it is parallel to the
A coaxial reflective photoelectric switch, which is set to have a shorter detection distance than the coaxial reflective photoelectric switch, is placed at the same height as the reflector on the front surface of each of the self-propelled carts, and the self-propelled trolley is moved at a low speed on a straight section or at a medium speed on a curved section. The curvature of the curved part of the track and the distance between the self-propelled bogies that should be maintained are used to give a stop command to the self-propelled bogie on the straight section of the track and for the stop command on the curved section. It is tilted at an inclination angle corresponding to the distance so that when the rear self-propelled vehicle approaches the front self-propelled vehicle until at least the above-mentioned inter-vehicle distance is reached, it can reflect coaxially to the reflector of the front self-propelled vehicle.
A collision prevention device for self-propelled trolleys that is installed facing forward.
