Abstract

The present invention discloses a movable visual inspection device for shield machines, comprising a rail and an inspection platform. The rail is installed on a shield tail, and the inspection platform includes a bottom plate, a shell, a cleaning mechanism, a power storage control system, and a traveling mechanism. Inside the shell is a visual inspection mechanism with a camera box, a camera, and a stabilizer component. The traveling mechanism drives the bottom plate along the rail. The cleaning mechanism, consisting of a glass sheet, a reel driving part, and a cleaning film, keeps the camera lens clear. The reel driving part rotates the cleaning film, which slides against the glass sheet on the camera box. This invention enables multi-faceted and multi-angle visual inspection of shield machine segments, ensures a clear camera lens, facilitates automatic cleaning and inspection position adjustment, and enhances working efficiency and inspection effectiveness.

Abstract

A casting process of a central rotary joint includes the steps of obtaining an upper casting mold, a lower casting mold, and a sand core through 3-dimensional printing, inserting the chill into the sand core, placing the sand core with the chill in the lower mold, inverting the upper mold onto the lower mold to form a assembled mold and define a casting cavity and a vertical pouring channel connected to the casting cavity between the upper and lower molds, injecting liquid iron into the casting cavity through the vertical pouring channel, unmolding after the liquid iron is condensed to obtain the central rotary joint. Through the vertical pouring channel, the chill and related processes, the sequential solidification of the liquid iron is achieved, effectively avoiding deformation and shrinkage porosity caused by the shrinkage of the liquid iron and graphite expansion during the solidification process.
