Special-shaped cross-section shield segment erector

Abstract

The invention discloses a special-shaped cross-section shield segment erector which comprises a lifting device and a translation device, wherein the lifting device and the translation device are installed on a shield tunneling machine main body. The special-shaped cross-section shield segment erector further comprises a track, a trolley traveling device and a segment clamping and adjusting device. The trolley traveling device can be movably connected with the track along the track and connected with the shield tunneling machine main body through the track, the segment clamping and adjusting device is connected with the translation device and connected with the lifting device through the translation device, and the lifting device is fixed on the trolley traveling device. The special-shaped cross-section shield segment erector can meet assembly movement of special-shaped cross-section shield segments, completes the assembly movement intelligently, meets working condition requirements, and has the advantages of being convenient to control and strong in flexibility. Interference is not generated easily.

Description

technical field [0001] The invention relates to an assembling machine, in particular to a special-shaped section shield segment assembling machine for a special-shaped section shield. Background technique [0002] Tunnel shield excavation has gradually become the main means of urban underground construction by virtue of its own advantages. With the development of urban construction, subways and underground pipeline projects have continued to increase. The climax of the roadheader has carried out the experimental research and engineering application of the shield boring machine and construction technology for rectangular tunnels, elliptical tunnels, double-circular tunnels, and multi-circular tunnels. From the analysis of the function of the tunnel, in the urban traffic pedestrian tunnel, underground common trench, subway tunnel, etc., the application of special-shaped shield tunneling machine is more and more widely, so the research, development and application of special-sh...

AI Technical Summary

Problems solved by technology

Among them, the segment assembly technology is a key technology of the special-shaped shield. Usually, the assembly system of the special-shaped shield consists of two circular segment assembly machines, which cooperate to complete the assembly action. This method is complex to control and prone to interference.

Even if the working range of the original circular assembly machine is expanded by adding a two-stage lifting device, a left-right translation device, and a two-stage adjustment of the pliers to meet the assembly of rectangular segments, the actual structure is still similar to that of the circular assembly, and generally can only meet the requirements of the circular assembly. For the assembly of rectangular segments of a certain size, and the assembly of rectangular tunnel segments of large cross-section, such two assembly machines need to be used side by side to complete the assembly action. The control is complicated and has certain limitations.
