The invention discloses a shield tunneling machine and a cutter changing device thereof. A controller controls a front gate to be opened according to a received feedback signal when the pressure of anexcavation bin is consistent with the pressure of a transfer bin so that a cutter changing assembly can penetrate through the front gate to disassemble a hob on a cutter disc, controls the front gateto be closed according to a received disassembly signal after the cutter changing assembly carries the disassembled hob to return to the transfer bin, and controls a rear gate to be opened accordingto a received front gate closing signal when the pressure of the transfer bin is consistent with the pressure of a storage bin so that a cutter storage assembly can replace the hob clamped by the cutter changing assembly; and the controller controls the rear gate to be closed according to a received cutter changing signal after the cutter changing assembly returns to the transfer bin, controls thefront gate to be opened according to a received rear gate closing signal when the pressure of the excavation bin is consistent with the pressure of the transfer bin so that the cutter changing assembly can penetrate through the front gate to install the replaced hob to the cutter disc, and controls the front gate to be closed according to a received installation signal after the cutter changing assembly returns to the transfer bin. The hob can be replaced safely and efficiently.
Description
technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a shield machine and a tool changing device thereof. Background technique [0002] As an important tunneling equipment, the shield machine is widely used in major engineering fields such as urban subways, highway tunnels, and water conservancy projects. [0003] The cutter head of the shield machine is usually equipped with a number of hobs for cutting rock formations. The hobs will always wear out during the excavation process, and the hobs need to be replaced in time to improve cutting efficiency. Existing shield machines mainly rely on manual tool change. However, the excavation chamber of the shield machine is extremely narrow and has the characteristics of high pressure and high humidity, which threatens the personal safety of tool change operators and poses a high safety risk; The operating intensity of the knife is high, and the tool change time is long, whi...
