The invention discloses a bearing device for automobile maintenance, which comprises a wind-up roller, a wind-up roller, a wind-up plate, a wind-up plate and a wind-up plate, one end of the wire rod is connected with the outer wall of the winding roller, and the other end of the wire rod is connected with the mop head; wherein when the mopping head slowly ascends and supports the automobile, the wire rod is detached from the winding roller and pulls the winding drum to slowly rotate, and when the mopping head rapidly descends, the wire rod is detached from the winding roller and pulls the winding drum to slowly rotate. The arc-shaped blocks on the disc rotate rapidly with the virtual central axis of the disc as the rotation center, so that centrifugal force is generated correspondingly, and the arc-shaped plates rotate with the virtual central axis of the fixed shaft as the rotation center due to the centrifugal force; the elastic force of the tension spring is overcome, so that the resisting end of the arc-shaped plate moves in the direction away from the center of the circular groove, stretches out of the outer edge of the disc and then is in contact with the arc-shaped groove of the fixing ring to stop, the effects of limiting the mopping head from moving downwards rapidly and stabilizing the mopping head are achieved after the hydraulic oil cylinder breaks down, an automobile is prevented from being pressed downwards, and the personal safety of automobile maintenance personnel is protected.
本发明公开了汽车维修用承托设备,包括:收卷辊,弹性连接设置在所述架体上;线材,一端与所述收卷辊外壁连接,另一端与所述拖头连接;其中,当所述拖头缓慢上升并承托汽车时,则线材从所述收卷辊上卸下并拉动所述收卷筒缓慢旋转,当所述拖头迅速下降时。本发明中圆盘上的弧形块以圆盘的虚拟中轴线为旋转中心跟随迅速旋转,则相应地会产生离心力,离心力的出现使得弧形板以固定轴的虚拟中轴线为旋转中心旋转,克服拉簧的弹力使得弧形板的抵挡端向远离圆槽中心的方向移动并伸出圆盘外缘,后与固定环的弧形槽碰触停止,实现液压油缸发生故障后起到限制拖头迅速下移并稳住拖头的作用,防止汽车下压,保护汽车维修人员的人身安全。
