The invention relates to low-clearance hoisting equipment which is applied to hoisting pipe pieces in a tunnel excavator. The conveying trolley is arranged on the track, and the conveying trolley moves on the track in a reciprocating mode in the extending direction of the track; the loop chain lifting mechanism comprises a walking assembly, a lifting assembly and a lifting appliance; the walking assembly is arranged on the track, the walking assembly is connected with the transport trolley, and the walking assembly is driven by the transport trolley to move on the track in a reciprocating mode; the lifting assembly is arranged on the side face of the walking assembly and comprises a lifting power source, a driving wheel, a transmission wheel set, a driven wheel and a loop chain. The lifting mechanism does not occupy the space of a lifting assembly in the vertical direction, the overall clearance of the loop chain lifting mechanism is greatly reduced, and the lifting mechanism can be applied to small-diameter tunnel excavators to lift pipe pieces.

    本发明涉及一种低净空起重设备,应用在隧道挖掘机中吊运管片,包括:轨道;运输小车,设置在所述轨道上,所述运输小车沿所述轨道的延伸方向在所述轨道上往复移动;环链起升机构,所述环链起升机构包括:行走组件、起升组件和吊具;所述行走组件设置在所述轨道上,所述行走组件与所述运输小车连接,所述行走组件由所述运输小车带动在所述轨道上往复移动;所述起升组件设置在所述行走组件的侧面,所述起升组件包括:起升动力源、主动轮、传动轮组、从动轮和环链。本发明在竖直方向上不占用起升组件的空间,极大的降低环链起升机构整体的净空,能够应用在小直径隧道挖掘机中吊运管片。
