The embodiment of the invention provides a tower crane rotation braking method and device and a tower crane comprising the device, and belongs to the field of engineering machinery. The method comprises the following steps: detecting whether a tower crane slewing mechanism has an operation signal or not; detecting whether the tower crane slewing mechanism rotates or not and detecting the rotation direction of the tower crane slewing mechanism; and under the condition that the tower crane slewing mechanism has no operation signal and the tower crane slewing mechanism rotates, entering an auxiliary braking state, and in the auxiliary braking state, outputting a reverse torque opposite to the rotation direction to the tower crane slewing mechanism to limit or restrain the rotation of the tower crane slewing mechanism. According to the invention, rotation braking can be carried out by applying the auxiliary rotation braking force when unexpected rotation slippage of the rotation mechanism is caused under the conditions of strong wind or improper braking torque setting range of the brake of the tower crane rotation mechanism and the like, so that the unexpected slippage of the rotation mechanism is prevented.
本发明实施例提供一种塔机回转制动方法、装置及包含该装置的塔机,属于工程机械领域。所述方法包括:检测塔机回转机构有无运行信号;检测所述塔机回转机构有无转动及转动方向;以及在所述塔机回转机构无运行信号且所述塔机回转机构存在转动的情况下,进入辅助制动状态,其中在该辅助制动状态下,通过向所述塔机回转机构输出一与所述转动方向相反的反向转矩,以限制或约束所述塔机回转机构的转动。本发明可在大风或者塔机回转机构的制动器的制动力矩设定范围不当等情况下造成回转机构出现不期望的回转滑移时,通过施加一辅助回转制动力来进行回转制动,防止回转机构出现不期望的滑移。
