The invention belongs to the technical field of cargo transportation, and discloses a permanent magnet suspension crane device and an automatic centering method.The permanent magnet suspension crane device comprises a rack, a track, a trolley and a permanent magnet assembly, the track is arranged on the rack, and the trolley is located above the track; the first permanent magnet is arranged on the track and is obliquely arranged relative to the horizontal direction of the end face of the rack, the second permanent magnet is movably arranged on the trolley, is parallel to the first permanent magnet and is suspended, and when the trolley deviates towards one side close to the first permanent magnet, the repulsive force borne by the first permanent magnet is increased, and the repulsive force borne by the second permanent magnet is reduced; the trolley can deviate towards the side close to the second permanent magnet to be automatically centered, unbalance loading of the trolley can be prevented, it is guaranteed that the trolley can stably run all the time, the load capacity is high, zero-power suspension is achieved, friction loss is avoided, and compared with traditional electromagnetic deviation prevention, the structure is simple, energy consumption is low, the requirement for equipment is low, and the whole life cycle cost is low; and the device is suitable for long-distance and short-distance transportation and long-time work.
本发明属于货物运输技术领域,公开了永磁悬浮吊机装置及自动对中方法,该永磁悬浮吊机装置包括机架、轨道、小车和永磁组件,轨道设置于机架上,小车位于轨道的上方,第一永磁体设置于轨道上且相对机架的端面所在的水平方向倾斜设置,第二永磁体活动设置于小车与第一永磁体平行且悬浮设置,当小车向靠近第一永磁体的一侧偏移时,第一永磁体受到的斥力增大,第二永磁体受到的斥力减小,小车能够向靠近第二永磁体的一侧偏移而自动对中,能够防止小车发生偏载,保证小车始终能够平稳运行,负载能力强,零功率悬浮,无摩擦损耗,相较于传统的电磁防偏不仅结构简单能耗低,且对设备的要求低,全生命周期成本低,适用于长、短距离运输和长时间工作。
