The invention relates to a safety brake which comprises a cylindrical brake shell, a rotatable winding drum connecting piece is installed at one end of the shell, an annular brake disc is further installed at the other end of the shell, a center rotating shaft is installed in the center of the shell, and a brake disc corresponding to the brake disc is installed on the center rotating shaft. A first inner gear ring is arranged in the shell, and a planet carrier corresponding to the first inner gear ring is further installed in the shell. A planet gear meshed with the first inner gear ring is installed on the planet carrier, a sun gear meshed with the planet gear is arranged on the center rotating shaft, and the planet carrier is connected with the winding drum connecting piece. According to the safety brake, the planetary mechanism is arranged in the shell of the safety brake, the central rotating shaft provided with the sun gear is driven to rotate through the planetary mechanism when the crane drum rotates, the rotating speed of the central rotating shaft is larger than that of the crane drum, and the brake can brake the crane drum only by providing small torque; and the crane drum is reliably braked.
本发明涉及一种安全制动器,包括圆筒状的制动器壳体,壳体的一端安装有可转动的卷筒连接件,壳体的另一端还安装有环状的制动盘,壳体的中心安装有中心转轴,中心转轴上安装有与制动盘对应的刹车盘;壳体内设有第一内齿圈,壳体内还安装有与第一内齿圈对应的行星架;行星架上安装有与第一内齿圈啮合的行星齿轮,中心转轴上设有与行星齿轮啮合的太阳齿轮,行星架与所述卷筒连接件相连。本申请通过在安全制动器的壳体内设置行星机构,起重机卷筒转动时通过行星机构驱动设有太阳齿轮的中心转轴转动,中心转轴的转速大于起重机转筒的转送,制动器只需提供较小的扭矩即可对起重机卷筒进行制动,使得起重机卷筒制动可靠。
