The invention relates to the field of hoisting equipment, and discloses a tower crane and a mounting structure of a self-discharging counterweight, a balance arm of the tower crane is provided with the self-discharging counterweight (4) which is fixed at a mounting position through a self-discharging locking mechanism (3) and a grading locking mechanism (9), the self-discharging counterweight (4) comprises a plurality of balance blocks (4a), and the balance blocks (4a) are connected with the self-discharging locking mechanism (3) and the grading locking mechanism (9). The grading locking mechanism (9) is arranged to unlock the corresponding balance block (4a) according to the load torque of the cargo boom (23), and the self-discharging locking mechanism (3) can be triggered by a triggering device to release the self-discharging balance weight (4) and enable the corresponding balance block (4a) unlocked by the grading locking mechanism (9) to fall off from the installation position when the cargo boom ascends. The tower crane can be mechanically triggered to release the corresponding number of balance blocks on the balance arm according to the load moment when the cargo boom upwards rises relative to the tower body, so that the risk of overturning accidents is reduced by accurately inhibiting the upward rising of the cargo boom.
本发明涉及起重设备领域,公开了一种塔式起重机和自卸平衡重的安装结构,所述塔式起重机的平衡臂上安装有通过自卸锁止机构(3)和分级锁止机构(9)固定于安装位置的自卸平衡重(4),该自卸平衡重(4)包括多个平衡块(4a),所述分级锁止机构(9)设置为根据起重臂(23)的负载力矩而解除对相应平衡块(4a)的锁止,所述自卸锁止机构(3)能够在起重臂上扬时被触发装置触发为释放自卸平衡重(4)并使得被分级锁止机构(9)解除锁止的相应所述平衡块(4a)从安装位置脱落。该塔式起重机能够在起重臂相对塔身上扬时根据负载力矩机械地触发为释放平衡臂上的相应数量的平衡块,以通过精准地抑制起重臂的上扬而降低发生倾覆事故的风险。
