self-propelled vehicle

Abstract

PROBLEM TO BE SOLVED: To provide a self-travelling carrier capable of reliably completing deceleration before the load comes to a curve route, and preventing collapse or derail even though the weight of the load is large or the entire length is long. SOLUTION: The self-traveling carrier is supportively guided by a guide rail GR along a carriage route including a straight route SR and a curve route CR so as to self-travel. The self-traveling carrier includes: a road trolley 2 for supporting a load receiving body; a front trolley 1 positioned in front of the road trolley 2 and connected to the road trolley 2 by a connection rod 11; a rotation detection means 5 for detecting relative rotation around a vertical axis 1A of the front trolley 1 with respect to the connection rod 11; and a control means for decelerating the traveling speed based on the detection signal when the rotation detection means 5 detects the relative rotation around the vertical axis 1A of the front trolley 1 with respect to the connection rod 11 when the front trolley 1 enters the curve route CR from the straight route SR.

Description

technical field [0001] The present invention relates to a self-propelled vehicle, which is supported and guided by guide rails along a transport path including a curved path, and self-propelled. Background technique [0002] In a self-propelled vehicle that is supported and guided by a guide rail along a transport path including a straight path and a curved path, in order to prevent the collapse and derailment of the cargo when traveling on the curved path, it is necessary to make the traveling speed on the curved path faster than that on the straight line. Travel speed on the path is reduced. [0003] In such a self-propelled vehicle, as a vehicle configured to recognize a curved path on the vehicle side and reduce the running speed autonomously in order to save time and effort in recovery after a power failure and recovery from an abnormality, there are the following Vehicles, etc.: only the tape is continuously installed on the guide rail of the curved path, and a magnet...

AI Technical Summary

Problems solved by technology

[0006] In a structure like Patent Document 2, after detecting that the vehicle on which the cargo has arrived has reached the curved path, the control device performs control to reduce the travel speed, so it cannot be carried out before the cargo reaches the curved path or enters The deceleration is completed after several curved paths, so the cargo may collapse or derail depending on the weight or size of the cargo.

[0007] In addition, in the configuration like Patent Document 1, it is necessary to attach magnetic tapes to the guide rails of all the curved paths, so the cost increases.
