Rail bridge beam end jacking and repairing device

Abstract

The invention relates to a device and method for jacking up and overhauling the beam end of a railway bridge, which includes a displacement detection device arranged between adjacent T beams, anti-subsidence devices arranged on both sides of the T beam, and a remedial device for walking on the track; The anti-subsidence device includes anti-subsidence accessories linearly installed on both sides of the vertical beam, guide rails arranged on the T-beam, anti-collision elastic seats arranged at both ends of the guide rail, mobile hangers arranged on both ends of the guide rail, setting The side guide wheels and the bottom guide wheels which are respectively in contact with the guide track on the mobile suspension base, the suspension legs arranged at both ends of the mobile suspension base, and the suspension ropes connected between the suspension base and the anti-subsidence fittings. The invention has reasonable design, compact structure and convenient use.

Description

technical field [0001] The invention relates to a device and method for checking and repairing the beam end of a railway bridge. The invention relates to the field of inspection / detection and evaluation of the technical condition of a heavy-duty railway bridge, in particular to a device and method for measuring the beam end of a railway bridge. Routine inspection and real-time monitoring of longitudinal displacement and vertical displacement of beam ends and abutments. Background technique [0002] At present, "heavy freight freight" is another development focus of my country's railways after "passenger high speed". Due to impact and fatigue, bridge diseases appear in large numbers and develop rapidly. The beam end jacking disease is a relatively common disease in heavy-haul railways, which is specifically manifested as the gap between the adjacent span beam end or the beam end and the abutment is too small or tight, and in severe cases, the beam or abutment concrete collaps...

AI Technical Summary

Problems solved by technology

[0003]There are many reasons for the tightness of the beam end. Most of the bridges on soft soil foundation are caused by the instability of the foundation and the inclination of the abutment, which in turn causes the abutment to move forward or measure the inclination. In cold and rainy areas, frost heave often causes abutments to lean forward or tilt, and damage to supports can also cause longitudinal movement of beams, which in turn leads to tightness of adjacent bridge spans.

The number of beam end jacking diseases is relatively small, but once this kind of disease occurs, it will cause damage to the bridge expansion device and loss of function. endanger driving safety

At present, there are few studies on beam end jacking defects, and the inspection of the defects is mostly carried out by hanging balls or measurement methods. There is no reasonable and efficient beam end jacking daily inspection and long-term monitoring devices and methods, and it is difficult to accurately grasp the beam end. Keep track of the degree and development trend of the disease, and cannot achieve real-time remediation
