It is an indispensable equipment on the construction site of structures such as buildings, bridge towers or cooling towers. As the construction height of towers and other structures increases, self-elevating tower cranes continue to increase in height. After the tower crane exceeds the specified free height, it needs to be installed and attached, and the next attachment should be installed at intervals of a certain height according to the specified value.
如图1所示，现有塔吊包括现有塔身2、现有附着件3、塔吊起重臂4和塔吊平衡臂5，当建筑物、桥梁塔柱或者冷却塔等构筑物侧面1有倾斜角度的要求时，则随着高度的变化，塔吊的现有塔身2与建筑物、桥梁塔柱或者冷却塔等构筑物侧面的距离也有变化，因此，现有附着件的长度随之变化，有的附着件(位于上方的附着件)长度就会很长，导致此道附着件的附着角度较小，从而减弱了附着件的强度和稳定性，增加了附着件设计、制造和安装难度。As shown in Figure 1, the existing tower crane includes the existing tower body 2, the existing attachments 3, the tower crane boom 4 and the tower crane balance arm 5. When the requirements are met, as the height changes, the distance between the existing tower body 2 of the tower crane and the side of structures such as buildings, bridge tower columns or cooling towers also changes. Therefore, the length of the existing attachments changes accordingly, and some The length of the attachment (the upper attachment) will be very long, resulting in a smaller attachment angle of this attachment, thereby weakening the strength and stability of the attachment, and increasing the difficulty of designing, manufacturing and installing the attachment.
