Disassembling and installation method for tower crane attachment

Abstract

The invention provides a disassembling and installation method for a tower crane attachment. The disassembling and installation method comprises a steel wire rope fixing frame, a fixed pulley device, a fixed pulley B, a fixed pulley C and an installation rope, wherein the steel wire rope fixing frame and the fixed pulley device are sequentially fixedly arranged on a balance arm of a tower crane and between a lifting hoist and a tower cap, the steel wire rope fixing frame is installed on one side close to the tower cap, the fixed pulley B is fixed at the lower end of the joint of a crane beam and the tower cap, the fixed pulley C is fixed at the upper end of the tower cap, an installation lasso steel wire rope passes by the fixed pulley B and the fixed pulley C, and a grabber at one end is connected with a luffing trolley. Compared with the prior art, the disassembling and installation method provided by the invention achieves the installation and disassembling for the crane attachment by additionally arranging two pulley devices on the crane, and utilizing the lifting steel wire rope of the tower crane simultaneously, and the construction method is safe and reliable, and high in construction efficiency, so that the construction progress can be effectively promoted, and the construction safety can be ensured.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a method for removing and installing a tower crane attachment. Background technique [0002] There is no special device for the attachment and disassembly of tower cranes, but the installation and disassembly of tower cranes are necessary tasks during the use of tower cranes. Tower crane equipment manufacturers do not have special devices, so in order The operation can only move the 0.5-ton small winch to the rear balance arm of the tower crane to disassemble the attached support rod. Due to the small tonnage, the diameter of the hoisting wire rope is small and the rope capacity is small, but the weight of the attached support rod is heavy. , It is very easy to cause accidents such as small hoisting wire rope breakage and hanging objects falling during operation. Broken wire ropes need to be replaced before the work can continue, which affects the construction progress. At the s...

[0002] There is no special device for the attachment and disassembly of tower cranes, but the installation and disassembly of tower cranes are necessary tasks during the use of tower cranes. Tower crane equipment manufacturers do not have special devices, so in order The operation can only move the 0.5-ton small winch to the rear balance arm of the tower crane to disassemble the attached support rod. Due to the small tonnage, the diameter of the hoisting wire rope is small and the rope capacity is small, but the weight of the attached support rod is heavy. , it is very easy to cause accidents such as small hoisting wire rope breakage and hanging objects falling during operation. Broken wire ropes need to be replaced before continuing to work, which will affect the construction progress. At the same time, the falling of hanging objects will affect safe production

[0003] In addition, if the tower crane needs to be dismantled after the attachment is installed due to special reasons, it will be more difficult to install the attachment again.
