Abstract

A fast unloading device for segments of a shield machine relates to a device capable of fast unloading the segments on a service vehicle when the shield machine is used for tunnel construction and is designed mainly for solving the problem of slow segment unloading speed by the existing segment crane. The fast unloading device comprises a framework, wherein traveling wheels disposed at the bottom of the framework are arranged on a rail, and a hydraulic cylinder is arranged at the top of the framework. A left pulley disposed on the framework is installed on a left pulley shaft fixed on the framework and a left pulley framework, and the left pulley framework is connected with the framework. A right upper pulley and a right lower pulley which are disposed on the framework are installed on respective pulley shafts, the two pulley shafts are fixed on the framework and a right pulley framework, and the right pulley framework is connected with the framework. One ends of two steel ropes are fixed on a cylinder rod of the hydraulic cylinder, the other end of one steel rope is connected with a left lifting plate after winding the right upper pulley and the left pulley, and the other end of the second steel rope is connected with a right lifting plate after winding the right lower pulley. Segment protective plates are arranged at the bottoms of loop chains disposed at two ends of the left lifting plate and the right lifting plate. The fast unloading device has the advantage of fast segment unloading speed.

Description

Technical field: [0001] The invention relates to a device capable of quickly unloading segments on a service vehicle when a shield machine is used for tunnel construction. Background technique: [0002] Most tunnels are constructed using the shield machine method, with segments lining them. The segments required for construction are transported by the service vehicle, and the length of time for the service vehicle to transport the segments and unload the segments directly determines the construction speed. At present, the segment crane is used for unloading. When unloading, the segment crane lifts a segment from the service vehicle, sends it to the segment storage area, and then returns to lift the next segment. This process takes five minutes. Taking the domestic subway tunnel as an example, the service vehicle transports six segments at a time, and it takes 30 minutes for the segment crane to unload the segments. The unloading speed is slow and the efficiency is low, whi...
