The invention provides an electric wheel edge brake for a crane, and relates to the field of brakes. The brake arm is movably arranged on the base; the braking assembly is connected to the braking arm, and when the braking arm moves relative to the base, the braking assembly can be driven to make contact with the walking wheels so as to achieve braking; the driving reset mechanism is connected to the brake arm and used for driving the brake arm to rotate relative to the base so that the brake assembly can make contact with or be separated from the walking wheel. Wherein the brake assembly comprises a movable part, a fixed part and a locking piece, and the movable part is movably connected to the fixed part; the locking piece is used for locking the movable part and the fixed part; and when the locking piece is triggered, the movable part and the fixed part are separated from locking, so that the movable part can move towards the side of the walking wheel. Compared with the prior art, the method has the advantages that the braking efficiency of the crane is improved, and equipment damage or operation risk caused by over-emergency braking is avoided through gradual speed reduction.
本发明提供了一种起重机用电动轮边制动器,涉及制动器领域,本发明包括基座;制动臂,活动设置于基座;制动组件,连接于制动臂,制动臂相对基座活动时,可带动制动组件与行走轮接触,以实现制动;以及驱动复位机构,连接于制动臂,用于驱动制动臂相对基座转动,以使制动组件与行走轮接触或脱离;其中,制动组件包括活动部、固定部和锁定件,活动部活动连接于固定部;锁定件用于将活动部与固定部锁定;锁定件被触发时,活动部与固定部脱离锁定,以使活动部可向行走轮侧活动。本发明与现有技术相比,具有提高了起重机的制动效率,而且通过逐步减速避免了由于过急制动造成的设备损伤或操作风险的优点。
