A dual-purpose gantry crane for shield machine assembly and slag discharge

Abstract

The invention discloses an assembling and muck discharging dual-purpose gantry crane for a shield tunneling machine. The assembling and muck discharging dual-purpose gantry crane comprises a main beam structure. A lifting mechanism is arranged on the main beam structure and connected with a hoisting mechanism provided with muck containing devices in a hoisting manner. The lower portions of the two ends of the main beam structure are each connected with a stand column. Supporting devices for supporting the muck containing devices are fixed to the stand columns. The muck containing devices are eccentrically supported on the supporting devices during falling, and rollover muck discharge is completed through the dead weight of the muck containing devices. According to the assembling and muck discharging dual-purpose gantry crane, a shield tunneling machine assembling gantry crane can be refitted to form a muck discharge gantry crane, no other gantry cranes need to be arranged, multiple purposes can be achieved through one machine, time spent in the shield tunneling machine assembling and detaching process is effectively saved, the construction progress is effectively improved, and meanwhile sufficient production space is ensured for construction sites.

Description

technical field [0001] The invention relates to a dual-purpose gantry crane for shield machine assembly and slag discharge. Background technique [0002] In the construction of large-diameter earth pressure balance shields, gantry cranes for assembling shield machines are required. At the same time, gantry cranes for slag discharge are also required during shield construction. Since the structures of the two functional gantry cranes are different, multiple gantry cranes are required. , the purchase cost is higher. In the existing construction plan, the shield machine assembly gantry crane is used to complete the assembly of the shield machine before the excavation, and the shield machine is removed to assemble the gantry crane during the shield excavation process, and then equipped with a slag discharge gantry crane, which requires Purchasing at least two gantry cranes requires extremely high construction costs, and it takes a lot of manpower and material resources to compl...
