Problems solved by technology

[0002] With the rapid development of transportation, water conservancy, and urbanization tunnel projects, shield construction is becoming more and more important in the construction of underground tunnels. During the construction of shield tunnels, worn tools must be replaced. Due to the complexity and diversity of geology, In order to ensure the stability of the face and prevent the occurrence of water inrush and other phenomena, the tool change process must maintain a high soil pressure.

Abstract

The invention provides a detachable normal-pressure tool change device. The tool change device consists of a tool apron cutter device, a tool change safety cabin device and a cutter change device. Through close coordination of the tool change safety cabin device, the cutter change device and the tool apron cutter device, a shield under high water pressure is subjected to cutter change in a normal-pressure environment, the problem that a sealing element of a tool change safety cabin cannot be changed after being worn is solved, and the working comfort during normal-pressure tool change is improved; and the tool change device can be widely applied to a normal-pressure tool change cutter plate of a tunneling machine under high water pressure so as to protect the safety of cutter change workers and lower the construction risk and difficulty.

Description

technical field [0001] The invention relates to the field of shield machine manufacturing, in particular to a detachable atmospheric pressure tool changing device. Background technique [0002] With the rapid development of transportation, water conservancy, and urbanization tunnel projects, shield construction is becoming more and more important in the construction of underground tunnels. During the construction of shield tunnels, worn tools must be replaced. Due to the complexity and diversity of geology, In order to ensure the stability of the face and prevent the occurrence of water inrush and other phenomena, the tool change process must maintain a high soil pressure. Therefore, the tool changer must withstand the high pressure environment, the tool change time is long and the tool change efficiency is low, and It has a great impact on the health of tool changing personnel, especially in the case of large buried depth, high water pressure and long-distance tunnel constr...
