Multi-stage telescopic arm device and deep-digging excavator comprising multi-stage telescopic arm device
A multi-stage telescopic arm device and deep-digging excavator comprising the device. A telescopic arm (12), comprising an outer cylinder (13) and multiple stages of inner cylinder (21, 23), is provided on the distal end of a boom (4). The outer cylinder (13) has a telescopic cylinder (25) disposed thereon and telescopic stationary sheaves (31, 31') fixed thereon. The telescopic cylinder (25) is mounted on the outer cylinder (13) with a rod (25B) facing upward, and moves along the outer cylinder (13) with a tube (25A) as a free end. The tube (25A) of the telescopic cylinder (25) is provided with a sheave mounting fixture (30), and the sheave mounting fixture (30) is provided with telescopic movable sheaves (33, 33'). An expansion and contraction rope (34, 34') is wound on the telescopic stationary sheaves (31, 31') and the telescopic movable sheaves (33, 33').
