Sectional type flexible scraper tunnel cleaning device
The invention belongs to the technical field of nuclear power, and particularly relates to a sectional type flexible scraper tunnel cleaning device. According to the device, under the condition that the swing mechanism drives the eccentric wheel to rotate, the transmission rod drives the multiple tool bit rocker arm pieces to move synchronously, and the blades located on the protruding portions of the tool bit rocker arm pieces move towards the inner wall of the tunnel firstly, scrape attachments attached to the outer layer of the inner wall of the tunnel and retract under driving of the rocker arms; in the retracting process of the blade located on the protruding portion of the tool bit rocker arm piece, the blade located at the upper end of the tool bit rocker arm piece moves towards the inner wall of a tunnel, scrapes attachments on the inner layer more deeply and retracts under the driving of the rocker arm, and therefore the rocker arm is driven by the swing mechanism to drive the tool bit rocker arm piece to form reciprocating type planing and hoeing actions, and the planing and hoeing effects of the tool bit rocker arm piece are improved. And the attachments can be removed at different depths twice through each reciprocating motion, so that stubborn attachments can be removed more thoroughly, and the tunnel cleaning efficiency is greatly improved.
本公开属于核电技术领域，具体涉及一种分段式柔性刮刀隧洞清理装置。本公开中，回转机构驱动偏心轮转动的情况下，通过传动杆带动多个刀头摇臂片同步运动，位于刀头摇臂片凸起部的刀片最先朝向隧洞内壁运动，刮切附着在隧洞内壁外层的附着物，并在摇臂的带动下回缩；在位于刀头摇臂片凸起部的刀片回缩的过程中，位于刀头摇臂片上端的刀片朝向隧洞内壁运动，并更深入地刮切里层的附着物，并接着在摇臂的带动下回缩，这样，摇臂在回转机构的驱动下，带动刀头摇臂片形成往复式刨锄式动作，每一个往复运动可以分两次对附着物进行不同深度的清除，有利于更为彻底地清除顽固附着物，并由此大大提到了隧洞清理的效率。
