TBM and continuous deslagging device thereof

Abstract

The invention discloses a TBM and a continuous deslagging device thereof. The continuous deslagging device comprises a screw conveyer, a first conveyor, a grab bucket and a second conveyor. The firstend of the screw conveyer is arranged on a slag accumulating area at the bottom of a cutterhead. The second end of the screw conveyer is arranged above a slag accumulating area at the bottom of a mainbeam. The first end of the first conveyor is located between the second end of the screw conveyor and the slag accumulating area at the bottom of the main beam. The grab bucket is used for grabbing accumulated slag located on the slag accumulating area at the bottom of the main beam and grabbing the accumulated slag to the first conveyor. The second conveyor is arranged below the second end of the first conveyor, so that the second conveyor receives the accumulated slag conveyed by the first conveyor and the accumulated slag grabbed by the grab bucket. According to the continuous delsagging device, the accumulated slag at the bottom of the cutterhead and the bottom of the main beam can be fast removed, so that the phenomenon that when the TBM passes through a crushed zone or other unfavorable geologies, due to the fact that a large amount of slag is accumulated at the bottom of the cutterhead, the cutterhead is blocked; and meanwhile the bottom deslagging efficiency of the open main beam of the TBM is improved, and it is guaranteed that the TBM fast passes through the surrounding rock crushed zone and other unfavorable geologies.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a TBM and a continuous slag cleaning device thereof. Background technique [0002] With the development of national science and technology and economy, the investment in infrastructure construction is increasing year by year. At the same time, higher requirements are put forward for construction safety, environmental protection and efficiency. Therefore, TBM is widely used in tunnel construction of water conservancy and hydropower, rail transit and municipal engineering. middle. While TBM is widely used, it also puts forward new requirements for the adaptability of TBM in different formations. When TBM passes through bad geological conditions such as broken zones, a large amount of rock slag will accumulate at the bottom of the cutter head and the bottom of the main beam, which will affect the tunneling efficiency of the TBM, seriously Sometimes it will cause proble...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a TBM and its continuous slag removal device, which can quickly clean the slag accumulation at the bottom of the cutter head and the bottom of the main beam, so as to solve the problem of a large amount of slag accumulation at the bottom of the cutter head when the TBM passes through the bad geology such as the broken zone. It will lead to the phenomenon of cutter jamming, and at the same time improve the efficiency of slag cleaning at the bottom of the main beam of the open TBM, so as to ensure that the TBM can quickly pass through the bad geological conditions such as the surrounding rock fracture zone
