Problems solved by technology

[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 o

Embodiment Construction

[0026] The invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0027] Such as Figure 1-Figure 2 As shown, a device for attachment, disassembly and installation of a tower crane includes a steel wire rope fixing frame, a fixed pulley device, a fixed pulley B14, a fixed pulley C15, and installation ropes on the balance arm of the tower crane. Between the lift 1 and the tower cap 19, the wire rope fixing frame and the fixed pulley device are fixed in turn, the wire rope fixing frame is installed on the side close to the tower cap 19, and the fixed pulley B14 is fixed at the joint between the boom 18 and the tower cap 19. At the lower end, the fixed pulley C15 is fixed on the upper end of the tower cap 19, a lasso wire rope 22 is installed to bypass the fixed pulley B14 and the fixed pulley C15, and the hook 12 at one ...

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...
