CLIMBING DEVICE FOR CONSTRUCTION MACHINERY AND DISTRIBUTING MAST

摘要

A distributing mast and a climbing device of construction machinery are provided. The climbing device comprises an upright post, a first frame (100), a second frame (200) and a driving mechanism. The first frame (100) or the second frame (200) is fixed to the upright post. The driving mechanism comprises an actuation device (310) which is connected to the first frame (100) and the second frame (200) at the ends of it respectively. The first frame (100) and the second frame (200) are set with sliding fit in the vertical direction. In the unfolding state, the height of the frame body which is formed by the first frame (100) and the second frame (200) is more than the height of one floor. The extension of the actuation device (310) can make the first frame (100) and the second frame (200) move upward and downward relative to the predefined floor step by step,on the basis of each other, and make the upright post arise or fall down, so as to achieve the stepped climbing and falling down of the construction machinery. The driving mechanism arises with the climbing of the construction machinery by using the climbing device of construction machinery. There is no need to operate the driving mechanism of the climbing device of construction machinery individually, which simplifies the climbing process of construction machinery and improves the efficiency of climbing.
