Abstract

The invention discloses a landing gear for a stepping moving type propeller strut of a floating crane and landing steps of the landing gear, relates to the field of cranes, and in particular relates to a landing gear of a propeller strut of a heavy floating crane and landing steps of the landing gear. The structure of the landing gear comprises a propeller strut, a platform and a boat body, wherein the platform is arranged on the boat body; the propeller strut is hinged with the platform; the landing gear is characterized in that an upper screw rod assembly is arranged at the lower part of the propeller strut; a lower screw rod assembly is arranged in the position corresponding to the upper screw rod assembly at the upper part of the platform; the upper end and the lower end of a support bracket are respectively hinged with an upper guide pulley on the upper screw rod assembly and a lower guide pulley on the lower screw rod assembly. The landing gear has the characteristics that the landing gear is safe and reliable, the elevation speed is high, the structure is novel, the machining is simple and convenient, the use is convenient, and the like, so that the novel landing gear for the stepping moving type propeller strut of the floating crane integrates the reliability, the economy and the practicability.

Description

technical field [0001] The step-moving gable lifting device and the lifting steps thereof of the floating crane according to the present invention relate to the field of cranes, especially the lifting device and the lifting steps of the gable of the heavy-duty floating crane. Background technique [0002] At present, with the increase in the number of bridges and culverts being built on the sea / inland rivers, only leveling the jib can not ensure that the floating crane (especially the heavy-duty floating crane) can pass the bridge and culvert smoothly. Function. [0003] The gable lifting function refers to dropping the gable to the minimum limit height when passing a bridge or culvert, and then lifting the gable to the normal working position after passing the bridge or culvert. [0004] There are two traditional methods for the lifting and landing of the gable frame of the floating crane: the first is the lifting method driven by anchor winch or winch; the second is the l...
