Abstract

The invention provides a bridge support height adjusting system. The system comprises a base, a jacking device, an adjusting base plate assembly and a telescopic mechanism, a bridge support connecting part and a base plate accommodating part are arranged on the base, a bridge support connected with a bridge is detachably arranged on the bridge support connecting part, and an opening communicated with the base plate accommodating part is formed in one side of the bridge support connecting part; the end, away from the base, of the jacking device abuts against the bottom of the bridge; the adjusting base plate assembly is located in the base plate containing part and comprises a plurality of adjusting base plates which are arranged in a stacked mode; and the telescopic mechanism is located on the side, away from the bridge support connecting part, of the base plate containing part and used for pushing the adjusting base plate to the bridge support connecting part from the base plate containing part. Through cooperation of the jacking device and the telescopic mechanism, the adjusting base plate can be automatically added to the bottom of the bridge support after the bridge support is jacked, automatic adjustment of the height of the bridge support is achieved, and the adjusting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge support height adjustment system. Background technique [0002] High-speed railway is a major public infrastructure and lifeline project related to national security, national economic lifeline and national economy and people's livelihood. At present, the operating mileage of high-speed railways in my country has exceeded 40,000 kilometers, of which the bridge mileage accounts for a very high proportion of the line mileage, with an average proportion of more than 50%, and the highest proportion can reach 94.2%. [0003] With the increase of operation time, under the joint action of complex multi-source loads such as train load and temperature, the accumulative deformation and subsidence of the ballast bed will occur on the high-speed railway bridge, which will affect the high ride comfort of the line, the structural durability and the safety of traffic on the ...
