The invention provides a winching machine. The winching machine comprises a base; the winding piece is rotatably arranged on the base around the axis of the winding piece; the driving piece is arranged on the base, and the driving piece is in driving connection with the winding piece so as to drive the winding piece to rotate; the passive braking assembly comprises a centrifugal swing rod and a reset piece, the first end of the centrifugal swing rod is hinged to the wire winding piece, the hinge axis of the centrifugal swing rod is parallel to the axis of the wire winding piece, and the reset piece is arranged between the wire winding piece and the centrifugal swing rod so as to apply reset force swinging inwards to the second end of the centrifugal swing rod. Wherein the passive braking assembly has a braking state and a loosening state, when the passive braking assembly is in the braking state, the second end of the centrifugal swing rod swings outwards and can be connected with the base in a clamped mode, and when the passive braking assembly is in the loosening state, the second end of the centrifugal swing rod is separated from the base. According to the technical scheme provided by the invention, the problem that the winching machine cannot be braked in time when the active braking mechanism or the control part breaks down in the prior art can be solved.
本发明提供了一种绞磨机,该绞磨机包括:底座;卷线件绕其轴线可转动地设置在底座上;驱动件设置在底座上,驱动件与卷线件驱动连接,以驱动卷线件转动;被动制动组件包括离心摆杆和复位件,离心摆杆的第一端与卷线件铰接,离心摆杆的铰接轴线平行于卷线件的轴线,复位件设置在卷线件和离心摆杆之间,以向离心摆杆的第二端施加向内摆动的复位力;其中,被动制动组件具有制动状态和放松状态,当被动制动组件处于制动状态时,离心摆杆的第二端向外摆动并能够与底座卡接,当被动制动组件处于放松状态时,离心摆杆的第二端与底座分离。通过本申请提供的技术方案,能够解决相关技术中的绞磨机在主动制动机构或控制件故障时无法及时制动的问题。
