Displacement frame girder bridge inspection vehicle

Abstract

The invention relates to equipment for detection and maintenance of high-speed railways and track viaducts. Its purpose is to provide detection and maintenance methods for high-speed railways and track viaducts. The displacement frame girder type bridge inspection vehicle of the present invention includes bridge deck self-locking hook palms, triangular outriggers, cross-link beams, guide beams, cross-link beam lifting frames, rotating platforms, rotating platform lifting frames, main frame inner and outer frames, fixed truss structures, etc. , the outer frame of the main frame and the lifting frame of the rotating platform are connected with the rotating platform to form a channel for inspection and maintenance of the bridge. There are at least two groups of connecting beams or rotating platforms that are connected. The two connecting beams can be lifted up and down driven by their respective horizontal connecting beam lifting frames, and the rotating platform can be lifted up and down driven by their rotating platform lifting frames. This equipment can adapt to different Inspection and maintenance of simply supported concrete girder bridges and concrete continuous girder bridges of varying heights.

Description

technical field [0001] The invention relates to detection and maintenance equipment for high-speed railways and track viaducts, in particular to a displacement frame girder bridge inspection vehicle. Background technique [0002] At present, there are three main types of bridge inspection vehicles that have been put into use by railways and light rails in various countries: rail-type, sidewalk-type and under-bridge pre-buried track-type. [0003] The rail-type bridge inspection vehicle takes the main track as the track, has fast driving speed, stable structure, relatively mature technology, and has been applied both at home and abroad. Such as the Austrian PALFINGER PB4 railway bridge inspection vehicle and the Golden Eagle hanging basket bridge inspection vehicle used in my country's Qinghai-Tibet Railway. This type of rail-type bridge inspection vehicle needs to occupy the operating track, so it can only be carried out under the condition of the transportation skylight, an...

AI Technical Summary

Problems solved by technology

Since the optimal design of high-speed railway bridges in my country in 2008, considering the safety of high-speed trains, people are not allowed to pass on the bridge and other equipment when the train is passing, and the catenary pillars are set on the outside of the sidewalk. These measures have improved the closure and safety of high-speed railways. At the same time, it is extremely inconvenient to use sidewalk inspection vehicles on high-speed railway bridge decks

[0005] The pre-buried track under the bridge walking inspection vehicle adopts the track method, and the inspection vehicle track is placed under the bridge deck. The embedded parts for fixing the track need to be pre-embedded on the bridge web when the beam is made. This kind of inspection vehicle is used This method requires a large number of embedded parts and tracks, which is a large investment and reusable method, but this method increases a lot of bridge construction costs, and the inspection of railway track traffic bridge lines is limited, and the flexibility of equipment is severely limited
