Shield tunneling machine cutterhead capable of conveniently adjusting cutter distance

Abstract

The invention discloses a shield tunneling machine cutter head convenient to adjust a cutter distance. The shield tunneling machine cutterhead convenient to adjust the cutter distance comprises a body and four mounting plates, the four mounting plates are annularly arrayed at the top of the body, a plurality of cutter bodies are fixed to the top of each mounting plate, an inserting mechanism used for mounting the mounting plates is arranged below each mounting plate, each inserting mechanism is connected with an angle deflection mechanism used for adjusting the angle of the mounting plate, the deflection mechanism is further connected with a compensation mechanism used for further adjusting the angle of the mounting plate, an angle monitoring assembly used for monitoring the angle of the mounting plate in real time is further arranged in the body, a mud water bin is formed in the portion, below the mounting plate, in the body, and a freezing mechanism used for freezing mud is arranged between the mud water bin and the mounting plate. According to the shield tunneling machine cutter head, the single mounting plate is detached, so that a single cutter can be conveniently replaced and maintained, and the working efficiency can be further improved.

Description

technical field [0001] The invention relates to the technical field of a shield machine cutter head, in particular to a shield machine cutter head for conveniently adjusting the cutter distance. Background technique [0002] In our country, it is customary to call the tunnel boring machine used in soft soil strata a shield machine, and the tunnel boring machine used in a rock stratum as a full-section tunnel boring machine. The basic working principle of shield tunneling method construction is a cylindrical steel component The soil is excavated while pushing forward along the axis of the tunnel. The shell of the cylindrical assembly is the shield, which acts as a temporary support for the excavated unlined tunnel section and bears the pressure of the surrounding soil layer, sometimes It also bears the groundwater pressure and keeps the groundwater out, and operations such as excavation, soil dumping, and lining are carried out under the cover of the shield. The existing shie...

[0002] In our country, it is customary to call the tunnel boring machine used in soft soil strata a shield machine, and the tunnel boring machine used in a rock stratum as a full-section tunnel boring machine. The basic working principle of shield tunneling method construction is a cylindrical steel component The soil is excavated while pushing forward along the axis of the tunnel. The shell of the cylindrical assembly is the shield, which acts as a temporary support for the excavated unlined tunnel section and bears the pressure of the surrounding soil layer, sometimes It also bears the groundwater pressure and keeps the groundwater out, and operations such as excavation, soil dumping, and lining are carried out under the cover of the shield. The existing shield machine cutter head that is convenient to adjust the cutter distance, in actual use, when it is necessary to adjust the cutter It is difficult to disassemble the cutterhead when the disk is replaced or repaired, and the work efficiency is extremely low
