A self-stabilizing tower crane

Abstract

The invention provides a self-stabilization type tower crane, and belongs to the technical field of tower cranes. The tower crane comprises a tower top, a cargo boom, a balance arm and an adjustment mechanism, wherein a first rotating shaft is rotationally arranged on the tower top, a first inertia wheel is fixedly arranged on the first rotating shaft, a second rotating shaft is rotationally arranged on the tower top, a second inertia wheel is fixedly arranged on the second rotating shaft, a third rotating shaft is rotationally arranged on the tower top, a winding drum is fixedly arranged on the third rotating shaft, a traction steel wire rope is wound around the winding drum, a transmission mechanism can drive the first inertia wheel and the second inertia wheel to rotate at the same timethrough the rotation of the winding drum, the cargo boom is fixedly arranged on the left side wall of the tower top, the balance arm is fixedly arranged on the right side wall of the tower top, the balance arm comprises an electric winch, a sliding groove hole and a balance block, the electric winch is fixedly arranged on the balance arm, one end of the traction steel wire rope is wound around aroller of the electric winch, and the balance block is horizontally arranged in the sliding groove hole in a sliding mode. The tower crane can be automatically balanced during working.

Description

technical field [0001] The invention belongs to the technical field of cranes and relates to a self-stabilizing tower crane. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites. It is used to hoist construction materials such as steel bars, wooden corrugated pipes, and scaffolding pipes. It is an indispensable equipment for construction. [0003] When the tower crane is performing high-altitude hoisting operations, it is greatly affected by the wind, and the lifting arm and the balance arm will sway left and right, which will easily cause the torsional moment of the tower body mechanism and cause the tower body to bend and deform; in addition, the balance on the balance arm of the existing tower crane The blocks are all fixed, but due to the different weights of the lifting objects, the boom and the balance arm cannot be balanced, and it is easy to shake up and down, causing the tower crane to collapse or the boom to br...
