Description

Technical Field

The tool is usually used to excavate the soil while advancing forward along the axis of the tunnel. After use, the tool is removed and replaced through a device for quickly disassembling the shield machine tool.

[0003] For example, a quick installation device for shield machine tools with Chinese patent application number CN202320855112.X drives a bidirectional screw to rotate through a rotating motor, and moves two sets of nuts and brackets toward the center until the mounting blocks arranged on both sides of the tool body extend into the inner walls of the two sets of brackets. At the same time, when the rack passes through the inner wall of the bracket, it pulls the circular plate to drive the insertion rod and the insertion block to move, so that the rack can pass through the inner wall of the bracket until the two sets of brackets clamp the mounting blocks on both sides of the tool body, so that the spring resets when the tension is lost, and pushes the insertion block arranged on one side to reset until the insertion block is inserted into one side of the rack, so that the position of the rack can be fixed, and the position of the mounting block and the tool body can be fixed at the same time, which solves the problem that it is inconvenient to install and disassemble the tool using screws.

[0004] However, in actual use, after the above device disassembles the tool, a new tool needs to be reinstalled, and the position of the replaced tool on the two brackets is prone to deviation, thereby reducing the effect of replacing the tool after disassembly. Utility Model Content
