AI Technical Summary

Technical Problem

In existing technologies, the spray curing of tunnel segments is uneven, and manual operation is time-consuming and labor-intensive, making it difficult to achieve comprehensive spray coverage.

Method used

A curing frame for shield tunnel segment production was designed, which adopts a motor-driven rotating rod and nozzle structure. The rotating rod drives the nozzle to swing, so as to achieve uniform spraying on the top two sides and concave side of the shield tunnel segment. Combined with the setting of inclined nozzles, it ensures uniform coverage of all parts.

Benefits of technology

It achieves all-round uniform spraying of tunnel segments, reduces the intensity of manual labor, improves the quality of maintenance, and avoids local drying or insufficient maintenance.

Abstract

The utility model relates to the technical field of shield segment production, and discloses a maintenance frame for shield segment production, which comprises a placing table, a rectangular hole is formed in the middle of the placing table, L-shaped supporting legs are fixedly connected to two ends of the bottom of the placing table, and a same second transverse pipe is rotatably connected between the two L-shaped supporting legs close to the rectangular hole. The positions, located at the bottom of the second transverse pipe, of the two L-shaped supporting legs are rotationally sleeved with the same rotating rod, the two ends of the rotating rod rotationally penetrate through the close L-shaped supporting legs to be fixedly connected with rotating rods, round holes matched with the rotating rods are formed in the two L-shaped supporting legs, and the tops of the two rotating rods are fixedly connected with the same connecting rod. According to the pipe piece maintenance device, all parts such as the two sides and the concave side of the top of a pipe piece can be uniformly covered, local drying or insufficient maintenance is avoided, the maintenance quality is greatly improved, a worker does not need to hold a spray head by hand for operation, the labor intensity of the worker is reduced, and the human input is reduced.
