Abstract

The invention provides a small-diameter shield segment rapid unloading device. The small-diameter shield segment rapid unloading device comprises a fixing frame, a lifting platform, an anti-rotation supporting shoe and a jacking mechanism, wherein the fixing frame is used for installing the lifting platform, the anti-rotation supporting shoe and the jacking mechanism, and comprises a base, a side vertical frame and a main cross beam; the lifting platform is used for lifting segments and driving the segments to move in the horizontal direction, and comprises a lifting arm, a fine adjustment device, a walking support and a telescopic oil cylinder; and the anti-rotation supporting shoe is used for being attached to the inner walls of the segments, and the jacking mechanism is used for driving the lifting platform to operate in the vertical direction, and comprises a jacking beam and a jacking oil cylinder. According to the small-diameter shield segment rapid unloading device, in a small clearance operation environment, the vertical direction position of the lifting platform can be controlled through the jacking mechanism, so that the segments can be rapidly and efficiently unloaded by utilizing the lifting platform, and the plurality of segments can be conveyed at the same time, and therefore the transportation and unloading time of the segments is saved, the working efficiency is improved, and the material transportation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling machines, and in particular relates to a small-diameter shield segment quick unloading device. Background technique [0002] In tunnel shield construction, the shield segment is the inner lining component used by the shield to permanently line the formed section, and it 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 working headroom, after the segment is transported to the designated location by the segment transport vehicle, the segment is unloaded from the transport vehicle to the segment pre-storage area by a single-segment crane until one time The segment transport vehicle can return to carry the next segment after the unloading of the segment is completed. In addition, due to the influence of the size of the net work space, in order to limit the overall height of the...
