Self-disassembling device of tower crane

Abstract

The invention discloses a self-disassembling device of tower crane, which is characterized in that a self-disassembling arm support device is arranged on an arm support of a tower crane, and a self-disassembling balancing-weight device is arranged on a balancing arm of the tower crane. The self-disassembling arm support device is characterized in that a mast type hoisting frame is arranged under the arm support, the lower ends of two masts are hinged on a variable-amplitude trolley, the upper ends of the two masts are connected through a steel wire, the front end of the front mast is provided with a hanging hook, the rear end of the rear mast is provided with hand chain hoist which is connected through the steel wire, the self-disassembling balancing-weight device is a door beam structure, supporting rods on both sides of the device are spanned on both sides of a balancing-weight, a pulley capable of horizontally moving is arranged on a cross beam, and a plate hook is connected on the pulley. The device enables the tower crane to realize the self-disassembling function, during establishing a tower, the inconvenience brought to the disassembly of the tower because of the limit of construction environment does not need to be considered, thereby the device provides convenience to users. Simultaneously, the cost of hiring a truck type crane and the mounting cost are saved, and the device has better economic benefits.

Description

1. Technical field [0001] The invention belongs to the technical field of tower crane disassembly, and in particular relates to a disassembly device for a tower crane arm frame and a counterweight. 2. Background technology [0002] Tower cranes are installed on site and then dismantled on site after the project is completed. Existing tower cranes are lifted and lowered through the sleeve frame, and truck cranes and other equipment are used for erecting and dismantling the tower, which limits the use environment of the tower crane. The workplace should be relatively open, and the truck crane can be entered and exited . In some cases, the tower crane cannot be lowered to the dismantling height after the work is completed, or the tower crane is wrapped inside the building after the work is completed, and the truck crane and other equipment cannot disassemble it to realize the lowering and dismantling of the tower. 3. Contents of the invention [0003] The purpose of the pre...
