Problems solved by technology

[0010] However, the entire boom is assembled on the ground, which requires a large assembly site, especially for super-large tower cranes, the length of the boom reaches 80 meters or longer, and it is impossible to provide an assembly site for narrow construction sites or water surface installations
In addition, the jib, jib tie rod, trolley, etc. are heavy, especially for super large tower cranes, the mass reaches more than 70 tons, the installation height is basically the highest, and lifting equipment with large lifting capacity is required. The installation cost is high; in addition, this type of lifting equipment also needs enough space, and large lifting equipment cannot be used in narrow construction sites

Embodiment Construction

[0043] The method for installing the boom of a tower crane of the present invention uses auxiliary installation pull rods to install the boom in sections. Please refer to figure 1 , the tower crane 100 includes an auxiliary installation tie rod 10 , a tower body 20 , a balance arm 30 , a balance arm tie rod 40 , a boom 50 , a boom tie rod 60 and a brace 70 . The top of the tower body 20 is provided with a revolving platform 22, and the ends of the balance arm 30, the brace 70 and the boom 50 are installed on the revolving platform 22 respectively. It can be understood that, according to different models, the slewing platform 22 may only include an upper support, and may further include a slewing tower suitable for setting a driver's cab. In the model in which the slewing platform 22 only includes the upper support, the balance arm 30 , the brace 70 and the jib 50 are respectively connected to the upper support. In the machine model in which the slewing platform 22 includes a...

Abstract

The invention provides a mounting method of a tower crane boom and an auxiliary mounting pull rod applied by the tower crane boom. The auxiliary mounting pull rod is used for temporarily pulling and hanging the crane boom on a balance arm or / and a rotating platform in the mounting process of a tower crane and comprises a tension state and a loose state; in the tension state, the auxiliary mounting pull rod is tensioned between the crane boom and the balance arm or / the rotating platform to temporarily pull the crane boom; and in the loose state, the auxiliary mounting pull rod is loosely connected between the crane boom and the balance arm or / and the rotating platform.

Description

technical field [0001] The invention relates to the field of tower crane boom installation, and in particular relates to a tower crane boom installation method and an auxiliary installation tie rod for its application. Background technique [0002] In recent years, with the in-depth development of the construction industry, construction tower cranes (referred to as tower cranes) have been widely used. The promotion and use of tower cranes has gradually changed the vertical and horizontal transportation methods of construction, created safe working conditions for operators, and improved work efficiency. [0003] When installing the entire tower crane, each component is assembled on the ground, and then the lifting equipment is used to complete the assembly of each component in the air. Since the boom is larger in size and heavier than other components, the hoisting equipment should be selected according to the quality of the boom when installing the tower crane. [0004] Ge...
