Abstract

The invention provides a bridge support height adjustment system. It includes a base, a jacking device arranged on the base, an adjustment backing plate assembly and a telescopic mechanism; the base is provided with a bridge support connection part and a backing plate accommodation part, and the bridge support connected to the bridge is detachably arranged on the bridge support On the connecting part, one side of the connecting part of the bridge support is provided with an opening communicating with the backing plate receiving part; the end of the jacking device away from the base is against the bottom of the bridge; the adjusting backing plate assembly is located in the backing plate receiving part, and the adjusting backing plate assembly It includes a plurality of adjustable backing plates arranged in layers; the telescopic mechanism is located on the side of the backing plate accommodation part away from the bridge support connection part, and is used to push the adjustment backing plates from the backing plate accommodation part to the bridge support connection part. Through the cooperation of the jacking device and the telescopic mechanism, the present invention can automatically add an adjustment backing plate at the bottom of the bridge support after it is jacked up, realize the automatic adjustment of the height of the bridge support, and improve the adjustment efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a height adjustment system for a bridge support. Background technique [0002] High-speed railway is a major public infrastructure and lifeline project related to national security, national economic lifeline, 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 bridge mileage accounts for a very high proportion of line mileage, with an average proportion of more than 50% and a maximum proportion of 94.2%. [0003] With the increase of operation time, under the combined action of complex and multi-source loads such as train load and temperature, high-speed rail bridges will experience cumulative deformation and subsidence of the track bed, which will cause serious damage to the high smoothness of the line, structural durability and traffic safety on the bridge. Negativ...
