Abstract

The invention discloses a pipe-segment quick-unloading device for a slope tunnel borer. The pipe-segment quick-unloading device is characterized by comprising a rear supporting trolley for a tunnel borer and a lifting unloader arranged on a rear supporting trolley; the rear supporting trolley comprises two bodies which are arranged in parallel at intervals and rigidly connected by a bracket; and the unloader is correspondingly arranged at the inner side of the interval on the two bodies. The pipe-segment quick-unloading device is an important part of a pipe-segment back-transporting system and can quickly unload the pipe-segment within a limited tunnel operating space, thereby improving the working efficiency of the pipe-segment back-transporting system and ensuring the construction progress and the efficiency of the slope tunnel borer process.

Description

technical field [0001] The invention belongs to tunnel boring machines for inclined shafts, in particular to a segment rapid unloading device for tunnel boring machines for inclined shafts. Background technique [0002] In recent years, tunnel boring machine construction has been widely used in underground tunnel construction due to its small impact on the ground and underground environment, fast excavation speed, and small surface settlement. In the construction of underground tunnels, the rapid support of tunnels is realized by segment assembly. At present, the tunnel boring machine has not designed a segment rapid unloading device, but is directly hoisted to the segment trolley in the segment assembly area by a segment crane. This segment transportation method is not suitable for inclined shaft tunnel boring machines. The segment transport vehicle of the inclined shaft tunnel boring machine cannot directly enter the front end of the inclined shaft tunnel boring machine t...
