Wear-resisting device for screw conveyor and application method thereof

Abstract

The invention relates to a wear-resisting device for a screw conveyor and an application method thereof. A mounting port is formed in a position where a barrel of the screw conveyor is in contact witha blade of the spiral conveyor, and the wear-resisting device is mounted at the mounting port. The wear-resisting device comprises a bottom plate detachably mounted on the outer side wall of the barrel for blocking the mounting port, a boss corresponding to the mounting port and fixed on the bottom plate and a sealing strip fixedly arranged on the bottom plate for blocking a space between the bottom plate and the outer side wall of the barrel, wherein the side part of the boss is attached to the edge of the mounting port, and the top surface of the boss has a radian matched with the inner side wall of the barrel, so that the boss is smoothly connected to the inner wall of the barrel. The wear-resisting device solves the problem that it is hard to repair the barrel of the screw conveyor effectively. The wear-resisting device is mounted at an easily worn part of the barrel in a detachable manner. When the wear-resisting device is worn, a new wear-resisting device is replaced directly, so that the repair difficulty is reduced, the construction efficiency is improved and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a wear-resistant device for a screw machine and an application method thereof. Background technique [0002] The screw machine is one of the host systems of the earth pressure balance shield machine. Its main function is to transport the muck cut by the cutter head to the belt conveyor through the rotation of the spiral blades of the screw machine, so as to realize the source of muck in the soil bin. It is continuously transported to the ground to ensure the normal progress of shield machine excavation. [0003] During the working process of the screw machine, due to the cantilever support structure of the screw rod and the blades, the screw blades at the soil bin may directly contact the inner wall of the cylinder under the influence of gravity, so as to wear the inner wall and even wear the inner wall of the cylinder. , after the inner wall of the barrel is worn through, s...
