Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and specifically discloses a tower crane support device. Background Technology

[0002] Tower cranes are one of the most commonly used lifting equipment on construction sites. Also known as tower cranes, they are used to lift and transport construction materials such as steel bars, timber, concrete, and steel pipes. Tower cranes are an indispensable piece of equipment on construction sites. During use, in order to ensure the balance and stability of the tower crane, a foundation needs to be installed under the tower crane. Tower cranes have a very large overturning moment and also have high requirements for the bearing capacity of the foundation. Therefore, the foundation of the tower crane is very important and is a necessary condition for maintaining the safe operation of the tower crane. The foundation of a tower crane is generally made of concrete. The length, width, height and reinforcement of the foundation need to meet the requirements of tower crane overturning stability, foundation bearing capacity and foundation crack resistance.

[0003] However, the foundation of tower cranes is fixed by concrete pouring, which has a long construction period. The concrete needs to be cured for a long time, which delays the construction period. Moreover, the demolition generates construction waste, which is costly and environmentally unfriendly, and cannot be reused.

[0004] With limited functionality, it cannot effectively secure the tower crane foundation and lacks a buffer structure for dynamic loads (such as wind force and hoisting vibration), which can easily lead to structural fatigue with long-term use.

[0005] The structure is fixed, and the height of the supporting structure cannot be finely adjusted according to the situation before the tower crane is installed, which is inconvenient to use. Utility Model Content
