Railway bridge detection trolley

Abstract

The invention discloses a railway bridge detection trolley, which comprises a frame, an operating mechanism, an industrial personal computer, an ascending and descending mechanism, a data acquisition device, a pitching mechanism, a remote controller, a local area network control station and a monitoring center. A power machine drives the operating mechanism to realize advance and retreat on a track arranged along a bridge railing; the power machine drives the ascending and descending mechanism to realize ascending and descending; and the pitching mechanism arranged at the lower end of the ascending and descending mechanism is driven to swing up and down by the power machine. The data acquisition device arranged on the pitching mechanism realizes comprehensive examination of a bridge through the composite motion of the operating mechanism, the ascending and descending mechanism and the pitching mechanism, and stores the examination data to the industrial personal computer; and the data can be forwarded to other storage equipment or remotely transmitted to the monitoring center, so that automatic monitoring of the bridge and automatic analysis of diseases are realized. Multiple operation modes can be realized, and a railway line does not need to be closed in the examination operation; and the railway bridge detection trolley has simple structure and high work efficiency, and can also be popularized and applied to common railway bridges and road bridges.

Description

technical field [0001] The invention relates to a bridge detection trolley, which is especially suitable for bridges on railway passenger dedicated lines. It belongs to a detection mechanical device. Background technique [0002] In recent years, the domestic high-speed rail has developed rapidly, and 60% of the high-speed rail lines are composed of bridges, so checking bridges is the main prerequisite for ensuring the safe operation of trains. At present, the inspection equipment of bridges is all vehicle-mounted. The inspection vehicle runs on the bridge surface. There are generally two inspection methods. One is to use the bracket to extend under the bridge, and then the inspectors will go down to the bridge for manual inspection; the other One is to send inspectors under the bridge for inspection by using the crutch arm suspension rail. Such bridge inspection equipment has the following disadvantages: one is to occupy the train running line during work, and the railway...

AI Technical Summary

Problems solved by technology

Such bridge inspection equipment has the following disadvantages: one is to occupy the train running line during work, and the railway line must be closed during inspection operations; the other is that the operation efficiency is low; It is necessary to manually get off the bridge for inspection, and human-machine cooperation has great potential safety hazards; fifth, manual inspection is easy to miss

When carrying out line sealing inspection on the line, due to the influence of factors such as the round-trip operation of the bridge inspection vehicle, the determination of the working position, and the presence of personnel, the effective inspection time is very small, and the train running line cannot be closed for too long. Existing equipment is far from meeting the needs of bridge inspection on passenger dedicated lines
