Abstract

本实用新型公开了一种盾构机用刮刀背面防磨损结构，该结构主要应用于隧道施工领域中的盾构机中，由刮刀保护板(1)、刮刀(2)组成。该装置利用刮刀保护板(1)堆焊耐磨层后在刮刀后面形成保护，解决刮刀背面磨损比较严重的问题，减少换刀频率，进而提高盾构机工作效率，降低施工成本。

Description

一种盾构机用刮刀背面防磨损结构
技术领域
本发明涉及建筑施工领域，主要应用于隧道施工中的盾构机中。
背景技术
在盾构法施工中，盾构机刀盘采用正反旋转的设计，刮刀在辐条上对称布置，正反向旋转刀盘时刮刀都能切削掌子面，如果正向旋转，反向用的刮刀背面磨损比较严重，导致刀具寿命缩短，更换刀具会对工期和效率有很大影响，刀具背后磨损是盾构施工中的一个难题.
发明内容
本实用新型提供一种盾构机用刮刀背面防磨损结构，可有效地解决当前盾构机刀盘刮刀背后磨损严重的问题。
本结构由刮刀保护板(1)、刮刀(2)组成。刮刀保护板(1)由普通钢材Q235A制作，表面有耐磨堆焊，耐磨材料相当HF-800，整体焊接在刮刀(2)的后面，两者之间有一定的间隙。
本实用新型提供了一种结构简单、制造成本低、可靠性高的刮刀背面防磨损结构，该结构可有效地解决刮刀背面磨损比较严重的问题，减少换刀频率，进而提高盾构机工作效率，降低施工成本。
