Abstract

The invention relates to a lifting system for a precast pier cap, in particular to a lifting system for lifting a precast pier cap composed of a main segment and an auxiliary segment, wherein the lifting system includes: a crane, the crane There is a horizontal support platform arranged on the upper part of the main section, and a pair of transportation tools are arranged on the horizontal support platform; a plurality of clamps are arranged on the horizontal support platform of the crane and moved by the transportation vehicle of the crane, and the clamps will assist the section fixed on the horizontal support platform; and an operation vehicle, which is set on the horizontal support platform of the crane and moves along the horizontal support platform by its own power. According to the present invention, the finished main section is set on the uppermost part of the pier body, and after a crane is set on the main section, the crane is used to lift more than one auxiliary section on the side of the main section, and then a clamp is used on the track of the crane The segments are fastened one after the other on the same line, so that the segments can be tensioned and fixed at the same time.

Description

technical field [0001] The invention relates to a lifting system for pre-casting pier caps, and in detail, it includes arranging a manufactured main section block on the uppermost part of a bridge pier main body; arranging a crane on the main section block, and using the crane to lift the side of the main section block After more than one auxiliary segment block is lifted, the segment blocks are sequentially fixed on the same line by means of clamps on the track of the crane, so that each segment block can be tensioned and fixed at the same time. Background technique [0002] In the upper part of the bridge pier, in order to support the girder, a pier cap with a width corresponding to the lateral width of the bridge is formed at the upper end of the main body. In the past, the piers were constructed on site from the bottom in sequence, and the upper part of the pier was assembled and cast, and then concrete was poured. [0003] On the one hand, if the bridge construction is...
