The invention provides a crane with good stability, and relates to the field of cranes. The top of the fixed base is rotationally connected with a rotating base, the rear side of the top of the rotating base is rotationally connected with an electric reel, a mooring rope is hinged to the electric reel, the front end of the mooring rope is connected with a hook frame, and the front side of the top of the rotating base is hinged to a large lifting arm. The front end of the large lifting arm is slidably connected with a small lifting arm, a wire stabilizing roll shaft is hinged to the bottom of the front end of the small lifting arm, auxiliary large arms are hinged to the left side and the right side of the front end of the large lifting arm, and the guide roller, the wire stabilizing roll shaft and the auxiliary small arms are matched with a wire guide groove and a reinforcing cylinder to conduct multiple guide on a cable, so that the stability of the cable during rotation of the crane is improved; the swinging amplitude of the cable is reduced, abrasion of the cable is reduced, potential safety hazards are greatly avoided, and the problems that the cable is poor in stability and serious in abrasion due to swinging of the cable in the hoisting and rotating process of the crane are solved.
本发明提供一种稳定性好的起重机,涉及起重机领域,包括固定底座;所述固定底座顶部转动连接有旋转底座,旋转底座顶部后侧转动连接有电动卷轴,电动卷轴上铰接有缆绳,缆绳前端连接有钩架,旋转底座顶部前侧铰接有起重大臂,其特征在于:起重大臂前端顶部铰接有导向辊轮,起重大臂前端滑动连接有起重小臂,起重小臂前端底部铰接有稳线辊轴,起重大臂前端左右两侧铰接有辅助大臂,在导向辊轮、稳线辊轴和辅助小臂与导线槽以及加强筒的配合,对缆绳进行多重导向,有利于提高起重机转动时缆绳的稳定性,减少缆绳的摆动幅度,降低缆绳的磨损,极大的避免了安全隐患,解决起重机起吊并转动的过程中缆绳摆动,导致缆绳稳定性差以及磨损严重的问题。
