Automatic control method and control system for driving of transporting girder vehicle through tunnel

Abstract

The invention belongs to the field of box girder erection transporting girder vehicles in high-speed railway engineering construction technology, and particularly relates to an automatic control method and a control system for driving of a transporting girder vehicle through a tunnel. The control system comprises a controller used for calculating, analyzing, processing and controlling received data, and a distance measuring system, an angle measuring system, a safety protection and alarm device, a human-machine interface, a steering control proportional valve and a driving control proportional valve which are connected with the controller. According to the method and the system, the central line offset of the transporting girder vehicle can be controlled automatically in a small range, so that collision between a box girder and the inner wall of the tunnel caused by large offset is avoided, the transporting girder vehicle can pass through a width-limited long curve tunnel safely and rapidly, and auxiliary components and facilities do not need to be added in the tunnel.

Description

technical field [0001] The invention belongs to the field of girder transport vehicles for erecting box girders in the construction technology of high-speed railway engineering, and in particular relates to an automatic control method and a control system for driving beam transport vehicles through tunnels. Background technique [0002] With the westward extension of my country's high-speed railway construction, beam trucks transporting box girders through tunnels have become increasingly popular. For long-distance and relatively narrow curved tunnels, when the beam transport vehicle transports the box girder through the tunnel, due to the limited distance between the two ends of the box girder and the inner wall of the tunnel, the box girder is likely to collide with the inner wall of the tunnel. It is impossible to quickly and safely pass through narrow and long curved tunnels in a fast and safe way, so how to ensure the safety of beam transport through tunnels has become ...

AI Technical Summary

Problems solved by technology

However, it is not only costly and time-consuming to use a special beam transport vehicle or to change the construction process of the box girder, but also it is difficult to guarantee the quality of the box girder, and it is also impossible to ensure that the beam transport vehicle can pass through the curved tunnel safely.
