The invention relates to the technical field of bridge support extraction, and discloses a bridge support extraction device which comprises a bottom plate and six sets of supporting legs fixedly mounted on the lower surface of the bottom plate, a jack is fixedly connected to the left side of the upper surface of the bottom plate, and the output end of the jack is fixedly connected with a top plate. The right side of the upper surface of the bottom plate is fixedly connected with a first electric push rod. According to the bridge support extracting device, by arranging a first electric push rod and a servo motor, two sets of arc-shaped clamping plates on the left side and the right side can fix a new bridge support and a bridge support needing to be replaced correspondingly, and then lifting motion and rotation can be conveniently and effectively conducted; according to the bridge support replacing device, the position of a new bridge support and the position of a bridge support needing to be replaced can be conveniently exchanged, the bridge support needing to be replaced can be conveniently and effectively extracted and replaced, labor is saved in use, the working intensity of workers is reduced, and the replacing safety of the bridge support is also improved.
Description
technical field [0001] The invention relates to the technical field of bridge bearing extraction, in particular to a bridge bearing extraction device. Background technique [0002] The bridge bearing is a device that supports the upper structure of the bridge. Under the action of load, temperature, concrete shrinkage and creep, the bearing can adapt to the corner and displacement of the upper structure, so that the upper structure can be freely deformed without generating additional additional internal force. [0003] In order to ensure the driving safety of the bridge and the smooth traffic, the old supports need to be replaced. The existing replacement method is to use jacks to lift the bridge, manually use tools to clamp the bridge supports, and then replace the supports. The labor intensity is high and the safety is low. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] In view of the deficiencies of the prior art, the present invention provide...
