ROBOT FOR CLIMBING/LOWERING LADDER

摘要

PURPOSE:To improve the mounting capacity of ladder climbing/lowering robot by providing a belt movable in climbing/lowering direction of ladder in gripper climbing/lowering mechanism thereby reducing the size and the weight of said mechanism. CONSTITUTION:Gripper climbing/lowering mechanisms 33A-D are provided with correspondence to four grippers 11A-D and constituted respectively with gripper elevating motors 35A-D, warm gears 37A-D and timing belts 39A-D. Said motors 35A-D are driven independently to move the timing belts 39A-D up and down through respective warm gears 37A-D thus to move respective grippers 11A-D accordingly up and down. The grippers 11A-D can be stopped at random position through driving/stopping of said motors 35A-D.
