DEVICE CAPABLE OF ADHERING BY SUCTION TO OBJECT SURFACE AND TRAVELING THEREALONG

摘要

To provide a simple, lightweight, and low-cost device that is capable of adhering by suction to an object surface and moving therealong. This device is at least formed from a suctioning unit, horizontally reciprocating units, vertically reciprocating units, and double-acting leg members. As a first step for enabling the device to travel along an object surface, the double-acting leg members are strongly pressed against the object surface. As a second step, the suctioning unit is moved in the traveling direction of the device with the double-acting leg members strongly pressed against the object surface. As a third step, the double-acting leg members are separated from the object surface. As a fourth step, with the double-acting leg members separated from the object surface, the double-acting leg members are moved in the traveling direction of the device and returned to the state immediately prior to the first step. Thereafter, the actions of the first to fourth steps are repeated.

主权项

1. A device capable of adhering to an object surface and traveling therealong comprising:
an adhering unit adhering to the object surface by the action of negative pressure; horizontal reciprocation units respectively arranged on right and left sides of the adhering unit with respect to the moving direction thereof, and capable of reciprocating in a front-back direction of the moving direction; vertical reciprocation units mounted on each of the horizontal reciprocation units and capable of reciprocating in the direction intersecting with the object surface; and double-acting leg members made of a material having a large friction coefficient like a polyurethane, respectively mounted on the vertical reciprocation units, and capable of reciprocating in the direction intersecting with the object surface; in which, in order to enable the device adhering to the object surface to travel along the object surface; as a first step, the double-acting leg members are strongly pressed against the object surface by the action of the vertical reciprocation units; as a second step, the adhering unit adhering to the object surface is moved in the traveling direction of the device by driving the horizontal reciprocation units while maintaining the state that the double-acting leg members are strongly pressed against the object surface; as a third step, the double-acting leg members are separated from the object surface by the action of the vertical reciprocation units; as a fourth step, the double-acting leg members are moved in the traveling direction of the device and are returned to the state immediately before the first step by driving the horizontal reciprocation units while maintaining the state that the double-acting leg members are separated from the object surface; and the operations of the first to fourth steps are repeated thereafter, by which the device adhering to the object surface travels intermittently therealong.
