Abstract

The invention relates to the technical field of tunnel boring machines, in particular to a TBM multistage muck discharging device. A first-stage belt conveyor is arranged in a shield body of a TBM andis of a stretchable structure, except a tail trailer, each trailer section is provided with a middle-stage belt conveyor, the head driving part of the first-stage belt conveyor is in lap joint with the tail muck receiving part of an adjacent middle-stage belt conveyor up and down, the adjacent middle-stage belt conveyors are in lap joint end to end in sequence, a tail-stage belt conveyor is arranged on the tail trailer, the tail of the tail-stage belt conveyor is in lap joint with the head of an adjacent middle-stage belt conveyor, the head of the tail-stage belt conveyor is in lap joint witha muck receiving vehicle, and adjusting devices are installed on the head sides and the tail sides of each middle-stage belt conveyor and the tail-stage belt conveyor separately and used for adjusting the position relation between each belt conveyor and the trailer. The multistage muck discharging method for the small-turning-radius TBM for a pumped storage power station adopts the device for muck discharging. According to the device and method, the problems of muck spilling, falling and deviation of the belt conveyors during muck discharging are solved.

Description

technical field [0001] The invention relates to the technical field of tunnel boring machines, in particular to a TBM multi-stage slag discharging device and method. Background technique [0002] In the curved excavation of small turning radius TBMs used in pumped storage power plants, changes in the attitude of the roadheader will affect the normal operation of the belt conveyor, causing belt deviation, sprinkling, and falling of the conveyor belt, affecting slag discharge The normal and stable operation of the system. The smaller the radius of the tunneling curve of TBM equipment, the more difficult it is to excavate the slag. The curved transportation of muck on TBM equipment is the limiting factor for the wide application of TBM in small curved fields. Contents of the invention [0003] The purpose of the present invention is to address the above existing problems and deficiencies, to provide a TBM multi-stage slag discharge device and method, which solves the proble...
