Pipeline extension device for shaft boring machine

Abstract

This utility model relates to the field of tunneling equipment technology, and more particularly to a pipeline extension device for a vertical shaft tunneling machine. It includes a support body, a pipeline extension mechanism, and a drive mechanism. An arc-shaped chain groove is formed on the support body along its circumference. The pipeline extension mechanism includes a pipeline connector and a chain. The pipeline connector is slidably mounted on the support body. The vertical ring of the chain is slidably mounted within the arc-shaped chain groove, and the horizontal ring of the chain is slidably mounted at the edge of the arc-shaped chain groove. The chain is fixedly connected to the pipeline connector. The drive mechanism includes a drive assembly and a sprocket. The sprocket is connected to the output shaft of the drive assembly, and the sprocket meshes with the chain. The drive assembly can drive the chain along the arc-shaped chain groove via the sprocket for line take-up or release. In this utility model, the arc-shaped chain groove effectively limits the chain, preventing lateral deviation and providing support throughout the process. This effectively reduces chain slippage and jamming, ensuring the stability of the pipeline extension operation.
