Cutter Drive Seal Test Bench

Abstract

The invention discloses a cutter head drive sealing test bench, comprising: a sealing chamber; a power box including a power box block 1 and a power box block 2, and the power box block 2 is provided with a grease hole; a driving rotation device including a rotating The motor is fixed on the first block of the power box, the power transmission gear is fixed on the output shaft of the rotating motor, the rotating bearing meshes with the power transmission gear through the inner ring gear, the outer ring of the transmission bearing is fixed on the first block of the power box, and the force ring The front end is sealed and the rear end is fixed to the inner ring of the rotating bearing, and the outer sealing ring is fixed to the outside of the stressed ring; the bottom support frame is supported on the bottom of the sealing chamber and the power box; the equipment mounting frame for placing the auxiliary system. Test the driving seal ring by simulating the soil quality, pressure, and cutter head speed of the corresponding project, and select the seal ring that meets the working conditions, thereby improving the reliability of the cutter head drive and improving the safety of the shield machine construction personnel.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a cutter head drive sealing test bench. Background technique [0002] In China, shield tunneling machines have been widely used in the construction of subway tunnels, highway tunnels, and underground pipelines due to their excellent ground subsidence control, high excavation efficiency, and wide-ranging ground adaptability. [0003] The drive seal of the cutter head is an important part to ensure the normal operation of the cutter head drive of the shield machine. Once the drive seal is damaged, it will cause leakage and affect the normal operation of the drive; if it is serious, it will cause water to enter the shield machine and affect the safety of internal construction personnel. . In order to ensure the reliability of the driving sealing ring, the present invention researches and obtains a cutter head driving sealing test bench, which can conduct experiments on ...
