Description

TECHNICAL FIELD

[0001] The utility model belongs to tower crane technical field, concretely relates to adjustable tower crane base support frame for base. BACKGROUND

[0002] With the acceleration of urbanization process, the construction industry is booming, high-rise buildings, large industrial facilities and complex bridge projects and other projects are more and more. These engineering projects also increasingly improve the requirements of tower crane. For example, in the super high-rise building construction, the tower crane needs to lift heavier building materials at a higher height, and the accuracy and stability of the hoisting process need to be ensured. The traditional fixed base support frame is difficult to meet these complex working condition requirements. Because the ground conditions of the construction site are complex and diverse, there may be uneven, soft soil and other conditions, which requires a base support frame that can adapt to different site conditions and can be flexibly adjusted to ensure the safe use of the tower crane.

[0003] The adjustable tower crane base support frame has the following disadvantages: when the base support frame cannot be leveled, the center of gravity of the tower crane will deviate from the ideal vertical axis on uneven ground. Especially when subjected to external forces such as strong winds, the base support frame that cannot be leveled makes it difficult for the tower crane to resist lateral forces. Under normal circumstances, the horizontally placed base can evenly distribute the force on the bottom of the tower crane to resist horizontal forces such as wind load. But if the base is not level, the lateral force generated by the wind will make the already unstable tower crane swing more, greatly increasing the risk of accidents for the tower crane. The hoisting mechanism, luffing mechanism and slewing mechanism of the tower crane run on the unstable base, which will affect the working state of these mechanisms. When the hoisting mechanism lifts heavy objects, the tower body may tilt, causing the heavy objects to swing in the air, increasing the likelihood of heavy objects falling. Moreover, in this case, it is also difficult for the operator to accurately control the action of the tower crane, and operation errors are likely to occur, further endangering the safety of personnel and equipment on the construction site.
