Abstract

The invention discloses a non-pressurized tool changing device with an accurate positioning function, and relates to the technical field of shield tunneling machines. The non-pressurized tool changingdevice with the accurate positioning function comprises a tool apron and a protection cylinder, the two ends of the tool apron are fixedly connected with the inner surface of the protection cylinderseparately, one side of the tool apron is fixedly connected with one sides of a first fixing block, second fixing block and third fixing block separately, the second fixing block is located in the middle of one side of the tool apron, the first fixing block and the third fixing block are symmetrically distributed at the two sides of the second fixing block, and the other side of the second fixingblock is in fitting connection with the middle of one side of a tool bit. The non-pressurized tool changing device with the accurate positioning function has the advantages that on the one hand, position setting of the first fixing block, second fixing block and third fixing block at one side of the tool apron facilitates positioning of the tool bit, on the other hand, a wedge block of a chuckingdevice is inserted into a clamping groove in the tool bit to rapidly and tightly clamp the tool bit, thereby saving a lot of installation and debugging time.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a precisely positioned base of an atmospheric pressure tool changing device. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the tunnel axis to excavate the soil. The shell of the cylindrical component is the shield, which acts on the excavated unlined tunnel section. As a temporary support, it bears the pressure of the surrounding soil, and sometimes bears the pressure of the groundwater and keeps the groundwater out. Operations such as excavation, soil drainage, and lining are carried out under the cover of the shield. The current shield machine has the problems of insufficient cutting force of the front end cutter, difficulty in replacing the entire cutter head, and easy misalignment. [0003] A shield ...
