Abstract

The invention provides a quick unloading device for small-diameter shield segments, including a fixing frame, a lifting platform, an anti-rotation support shoe and a jacking mechanism, and the fixing frame is used for installing the lifting platform, the anti-rotation support shoe and the lifting mechanism. The lifting mechanism includes a base, a side stand and a main beam; the lifting platform is used to lift the segment and drive the segment to move in the horizontal direction, and it includes a lifting arm, a fine-tuning device, a walking Supporting and telescopic oil cylinders; the anti-rotation support shoes are used to fit with the inner wall of the segment, the jacking mechanism is used to drive the lifting platform to run in the vertical direction, and includes a jacking beam and a jacking oil cylinder. The invention can control the vertical position of the lifting platform through the jacking mechanism under the small headroom working environment, so as to realize the rapid and efficient unloading of the segment by using the lifting platform and the simultaneous conveying of multiple segments. Thus, the transportation and unloading time of the segment is saved, which is beneficial to improve work efficiency and reduce material transportation costs.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling machines, in particular to a quick unloading device for small-diameter shield segments. Background technique [0002] In the construction of tunnel shield method, the shield segment is the lining member used by the shield to permanently lining the formed section, and bears the role of resisting soil pressure, formation water pressure and other loads. At present, in the actual small-section shield construction, due to the limited operating clearance size, after the segment is transported to the designated position by the segment transporter, the segment is unloaded from the transporter to the segment pre-storage area by a single segment crane until one After the unloading of the carrier segment is completed, the segment transporter can return to carry the next segment. In addition, affected by the size of the clear working space, in order to limit the overall height of the segment transpo...
