Title:
AUTOMATIC CLEANING DEVICE
Document Type and Number:
Japanese Patent JPH0453514
Kind Code:
A
Abstract:

PURPOSE: To reduce the weight of a traverse truck by providing a traverse truck having a cleaning means, which is engaged with horizontal rails to traverse, an elevating truck for transferring the traverse truck to an engaging position of the horizontal rails, and a traverse driving means for traversing the traverse truck.

CONSTITUTION: A hoisting device of a roof car 2 is operated, whereby an elevating truck 3 where a traverse truck 6 is installed is lowered to a cleaning floor of a building 1 and stopped. A running motor 10 of the traverse truck 6 is driven to roll driving wheels 11, and simultaneously a traverse assisting motor 13 is driven, so that a pinion gear 13b is rotated to generate the running force in a rack 12. The traverse truck 6 traverses from the elevating table 3 to horizontal rails 5. At this time, even if a difference in level in a connecting portion 5A between holding rails 3a and the horizontal rails 5 is caused, the driving wheels 11 can pass the difference in level by the running force produced by the traverse assisting motor 13. After the traverse truck 6 traverses to the horizontal rails 5, the pinion gear 13b is disengaged from the rack 12, and the traverse truck 6 traverses, with the driving wheels 11 rolled by the running motor 11, whereby a cleaned surface is automatically cleaned.
