PNEUMATIC PRESSURE DEVICE FOR LAYING POWER LINES AND METHOD FOR CONTROLLING SAME

摘要

The present invention relates to a pneumatic pressure device for a power line-laying robot, which causes reciprocal movement of the power line-laying robot and comprises: an initiation valve for initiating supply of air having a specific pressure; a main valve for selectively supplying air to or exhausting air from a pneumatic cylinder according to the operation of the initiation valve; a control valve for controlling the operation of the main valve by adjusting the duration of exhausting of the air exhausted from the main valve; and a cylinder which moves reciprocally according to the operation of the main valve. As a result, the size of the pneumatic pressure device can be made compact by optimally arranging valve circuits in the pneumatic pressure valve, the size of a robot used in a small space can be reduced, the maximum travel distance of the pneumatic cylinder can be secured, and responsiveness of the pneumatic cylinder can be increased.
