Abstract

The invention provides a shield tunneling machine tool disc system. Automatic tool changing can be achieved, and the safety of operators can be guaranteed when tools are changed. The invention provides a shield tunneling machine tool disc tool changing method which adopts the shield tunneling machine tool disc system. According to the shield tunneling machine tool disc system, the shield tunneling machine tool disc system comprises a tool disc, and a muddy water bin, an air cushion bin, a manhole bin and an automatic tool changing device which are sequentially arranged behind the tool disc. The automatic tool changing device comprises a sliding rail moving platform, a six-degree-of-freedom mechanical arm, a tail end actuator and an electrical cabinet used for controlling the equipment above, wherein the manhole bin comprises a manpower working area, a robot working area and a tool area which are arranged at intervals, a first cabin door is arranged between the manpower working area and the tool area, a second cabin door is arranged between the robot working area and the tool area, a rear side channel capable of communicating is formed between the tool area and the rear side space of the tool disc system, and the rear side channel is closed by a third cabin door.

Description

technical field [0001] The invention relates to a shield machine cutterhead system and a cutter changing method thereof. Background technique [0002] During the use of shield machine equipment, especially in the environment with hard soil, the knives are prone to passivation and damage during the excavation process, and the knives need to be replaced underground. [0003] The existing technology adopts a manual method to replace the cutter. For a single-edged hob, the operator wears corresponding diving equipment and other protective equipment, enters the manhole chamber, the air cushion chamber, and finally arrives in the muddy water chamber to perform the knife change operation. During the tool change process, in order to prevent external soil from entering the mud tank, it is protected by pressurization. Therefore, the operator needs to perform tool change under high pressure environment, which puts certain requirements on the operator. At the same time, the pressurizat...
