Embodiment Construction

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] Such as Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, the vibration damping system for coupled vibration of a tower crane and a cable tower includes a tower crane 10 , a cable tower 20 and an attachment device 30 arranged between the tower crane 10 and the cable tower 20 .

[0025] The cable tower 20 includes a first part 21 and a second part 22 respectively arranged on two sides of the tower crane 10 , and the tower crane 10 is located outside the connecting line between the first part 21 and the second part 22 . The first part 21 and the second part 22 are arranged symmetrically along the center of the tower crane 10 .

[0026] The attachment device ...

Abstract

The invention provides a vibration reduction system and a vibration reduction method for coupling vibration of a tower crane and a cable tower. The vibration reduction system for the coupling vibration of the tower crane and the cable tower comprises a tower machine (10) and a cable tower (20), wherein the tower machine (10) is connected with the cable tower (20) through an attaching device (30);and the attaching device (30) comprises a variable damping actuator. According to the vibration reduction system for the coupling vibration of the tower crane and the cable tower, effects of damping energy consumption and vibration reduction can be passively exerted, an effect of vibration control can be actively exerted, the coupling vibration of a tower crane-cable tower structure is greatly reduced, and the stability and the safety of the tower crane-cable tower structure are improved.

Description

technical field [0001] The invention relates to the field of construction hoisting machinery in construction machinery, in particular to a vibration damping system and a vibration damping method for coupled vibration of a tower crane and a cable tower. Background technique [0002] With the development of domestic infrastructure installation projects in the direction of large-scale, high-efficiency, and safety, and the construction of bridges, power plants, wind power, chemicals, and high-rise buildings, the demand for large-scale tower cranes is developing rapidly. Due to the development requirements of large span and light weight of modern bridge, in the design of bridge structure, the cable tower section is changed from traditional steel-concrete structure to steel structure, which not only reduces the quality of the bridge but also leads to the improvement of construction methods . The traditional construction method is manual pouring, which has low efficiency and canno...
