Abstract

The invention discloses an automatic replacing device for a hobbing cutter of a shield tunneling machine. The automatic replacing device comprises a main board, wherein a slide slot is formed in the main board; a fixed plate capable of sliding is arranged in the slide slot; a fixing device for fixing equipment is arranged in the fixed plate; a folding slot is formed in the bottom wall of the slideslot; and a slide block capable of sliding is arranged in the folding slot. The automatic replacing device is simple in structure, is convenient in operation, is convenient in maintenance, can automatically replace the hobbing cutter, prevents staff from operating under an environment higher than barometric pressure, guarantees body safety of staff, reduces labor intensity of a worker, improves cutter replacing efficiency of the shield tunneling machine, and has a relatively high use and popularization value.

Description

technical field [0001] The invention relates to the field of shield machine maintenance, in particular to an automatic hob replacement device for a shield machine. Background technique [0002] With the development of society, the use of shield machines to construct urban underground pipe networks is increasing. However, during the underground excavation process of shield machines, it is necessary to replace the heavily worn hobs to facilitate proper excavation. The replacement of machine hob underground hob is often done manually, with a low safety factor and high work intensity. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] Underground hob replacement of traditional shield machines often requires personnel to work in the air pressure chamber of the shield machine at an environment higher than atmospheric pressure, which is labor-intensive and low in safety. [...
