Multi-DOF Rectangular Segment Displacement Assembly Mechanism and Assembly Method

Abstract

The invention belongs to the technical field of tunnel construction equipment. A multi-degree-of-freedom rectangular segment displacement assembly mechanism and its assembly method, including: a column, a walking frame, a turntable, a lifting sleeve, a snatch arm assembly and a segment snatch turning assembly, the travel frame is arranged on a shield machine On the upper and lower corresponding slide rails of the tail shield, the walking frame is provided with traveling wheels and a walking power mechanism, the turntable is arranged between the column and the walking frame, and the turntable is slidably connected with the walking frame, and the lifting sleeve The matching sliding sleeve is arranged on the outside of the column, and the lifting sleeve is driven to slide up and down through the lifting power assembly; the snatch arm assembly is arranged between the segment snatch turning assembly and the lifting sleeve, and the segment snatch turning assembly can carry out the segment Grab and rotate the captured segments in a circumferential direction, so as to start the assembly of rectangular segments through this equipment. The application has the advantages of simple structure, high assembling accuracy, fast efficiency and good reliability, and can realize accurate and rapid positioning of any rectangular segment in half.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a multi-degree-of-freedom rectangular segment displacement assembly mechanism and an assembly method thereof. Background technique [0002] With the advancement of urbanization and urbanization in my country, the construction of rectangular tunnels such as urban crossing passages, subway entrances and exits, cable trenches, and underground comprehensive pipe galleries has developed rapidly in recent years. Traditional construction methods require road excavation or manual underground excavation. The construction cost is high, traffic is affected, and safety hazards are great, while the shield machine has the advantages of not needing to excavate the ground, occupying a small area, having little impact on traffic, and fast excavation speed. Compared with the circular tunnel section, the rectangular tunnel section can effectively reduce the excavati...

AI Technical Summary

Problems solved by technology

[0003] At present, the roadheaders developed and produced in China are relatively mature in circular cross-section excavation and short-distance rectangular pipe jacking machine excavation, but the development of long-distance rectangular shield excavation is relatively slow, and the application and promotion of rectangular shield is greatly restricted. Among them, the rectangular shield segment assembly machine is the main technical problem in the development of the rectangular shield machine

For this reason, the present invention proposes a new type of rectangular shield segment assembly machine, which is used to solve the problem of displacement assembly of rectangular segments
