Title:
PIT COVER OPENING/CLOSING DEVICE IN MOVING ELEMENT
Document Type and Number:
Japanese Patent JP3524901
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pit cover opening/closing device capable of increasing the life of a device by smoothly opening/closing a pit cover of a pit storing cabtyre cable without generating noise, and coping with speed-enhancement of a moving element.
SOLUTION: A groove-shaped pit 15 is formed along a traveling direction of a moving element, and a feeding element such as cabtyre cable 12 is stored. An upper opening portion of the pit is fully covered by a pit cover 17 divided into a plurality of pieces. The pit cover 17 is successively driven to open/close according to traveling of the moving element, thereby feeding electricity from a feeding element such as the cabtyre cable 12 to the moving element. An angle arm 21 guided out of the moving element side is disposed in the pit 15, and a large number of guide rollers 23 are rotatably arranged on an upper surface of the angle arm 21. In this pit cover opening/closing device in the moving element, one wire rope 24 is arranged along a peripheral surface of the guide rollers 23 by extending in a longitudinal direction of the pit 15.
