Abstract

The invention discloses a single-rope three-section type horizontal suspension arm folding buffering and self-locking device and relates to a horizontal suspension arm unfolding and folding mechanism. By the single-rope three-section type horizontal suspension arm folding buffering and self-locking device, the problem that a suspension-arm tower type crane cannot be bridged and installed flexibly and efficiently due to a longer suspension arm part can be solved. A guide rail is arranged in the middle of the second section of the arm; a sliding block is arranged on the guide rail in a sliding manner; the left side of the sliding block is dragged by a motor; a first guide pulley and a connecting sheet are arranged on the second section of the arm; a connecting plate is fixedly arranged on the third section of the arm; the connecting plate is connected with an obtuse triangle shaped reinforcement plate; the obtuse triangle shaped reinforcement plate is connected with a second connecting rod; the second connecting rod is connected with a first connecting rod; the first connecting rod is connected with a lug plate; the lug plate is arranged on the third section of the arm; the lug plate is connected with the connecting sheet; and one end of a steel wire rope is fixed on the sliding block and the other end of the steel wire rope bypasses the upper rim of the first guide pulley and then bypasses a second guide pulley and a third guide pulley so as to be finally fixed on the connecting plate. The single-rope three-section type horizontal suspension arm folding buffering and self-locking device is used in the suspension-arm tower type cranes.

Description

technical field [0001] The invention relates to a horizontal boom folding buffer self-locking device, in particular to a single-rope three-section horizontal boom folding buffer self-locking device, which belongs to the technical field of construction engineering. Background technique [0002] Tower cranes have the characteristics of large size and stability, and their booms are generally long. At present, the tower cranes used in the domestic construction industry are mainly old-fashioned traditional fixed boom tower cranes. In the structure of the traditional fixed boom tower crane, the boom is installed on the tower crane as a whole. The erection and dismantling process of the tower crane is cumbersome, and there are a series of disadvantages in the construction application, which delays the construction of the construction project. Period, especially in some crowded places, the use of traditional tower cranes is extremely inconvenient. There is a big gap between domesti...
