Title:
WINCH SYSTEM FOR WALL SURFACE SUCTION SELF-PROPELLENT APPARATUS
Document Type and Number:
Japanese Patent JP2022091648
Kind Code:
A
Abstract:
To provide a winch system for a wall surface suction self-propellent apparatus in which the winch system not only applies force in the upward direction to the wall surface suction self-propellent apparatus, but also does not prevent straight advancing ability of the wall surface suction self-propellent apparatus in the upward direction.SOLUTION: Two load sensors 34 and 44 for detecting tension of each wire rope of two wire ropes 32 and 42 and two angle sensors 37 and 47 for detecting an angle formed by each wire rope of the two wire ropes 32 and 42 and the gravitational line are provided. A computation is performed by a small-sized computer on the basis of data obtained by the two load sensors 34 and 44 and the two angle sensors 37 and 47, under the conditions that component of force of each tension of the two wire ropes 32 and 42 in the horizontal direction has the same value, and each tension of the two wire rope tractors is automatically controlled, thereby applying force in the upward direction to the wall surface suction self-propellent apparatus.SELECTED DRAWING: Figure 4
