The invention discloses a low-clearance double-beam suspended trolley crane, and relates to the technical field of cranes, in particular to a low-clearance double-beam suspended trolley crane which comprises a supporting cross beam, a walking trolley is movably mounted in the supporting cross beam, a fixing plate is fixedly mounted on the lower surface of the interior of the walking trolley, and driving machines are symmetrically arranged on the inner wall of the walking trolley; positioning holes are symmetrically formed in the outer wall of the walking trolley, driving shafts are fixedly mounted at the ends of output shafts of the driving machines and penetrate through the positioning holes, driving wheels are fixedly mounted on the outer walls of the driving shafts, and mounting grooves are formed in the outer walls of the driving wheels. The side edges of the multiple driving wheel bodies are separated from the inner wall of the supporting cross beam, when the driving wheels drive the trolley to move horizontally, it can be effectively avoided that the driving wheels abrade the side face of a rail of the supporting cross beam while it is guaranteed that the walking trolley moves in a positioning mode, the service life of the device is prolonged, and the maintenance cost is reduced; and the use safety degree of the device can be effectively improved.
本发明公开了一种低净空双梁悬挂小车起重机,涉及起重机技术领域,具体为包括支撑横梁,所述支撑横梁的内部活动安装有行走小车,所述行走小车的内部下表面固定安装有固定板,所述行走小车的内壁对称设有驱动机,所述行走小车的外壁对称开设有定位孔,多个所述驱动机的输出轴端部固定安装有驱动轴并贯穿定位孔,多个所述驱动轴的外壁固定安装有驱动轮,多个所述驱动轮的外壁开设有安装槽。本发明,多个驱动轮本体的侧边与支撑横梁内壁相分离,驱动轮在带动小车水平移动时,在保证行走小车定位移动的同时,能够有效避免驱动轮对支撑横梁轨道侧面造成磨损,提高了装置的使用寿命,降低了维护成本,并能够有效提升装置的使用安全程度。
