Abstract

The invention discloses a segment girder pre-stressed pipeline positioning device. The segment girder pre-stressed pipeline positioning device comprises a first mounting plate and positioning mechanisms, wherein the multiple positioning mechanisms are mounted on the upper surface of the first mounting plate in a spaced mode; each positioning mechanism comprises a second mounting plate, a rotary ring, a fixed ring, a first connecting rod, a mounting rod, a positioning reinforcing steel bar and a limiting assembly for limiting the rotary ring; each limiting assembly comprises a pawl, a ratchet and a spring; the bottom of each first mounting plate is equipped with a lifting assembly; and the lifting assembly comprises a bottom plate, a two-way lead screw, an inner threaded sleeve and a secondconnecting rod. The positioning mechanisms are arranged, the rotary rings are rotated clockwise, the rotary rings drive the connecting rods to move, and the connecting rods drive multiple positioningreinforcing steel bars to synchronously move towards pipelines through the mounting rods, so that quick pipeline positioning is realized, the pipelines are guaranteed to be concentric with through holes, operations are simple, convenient and quick, and working efficiency is improved; and lifting assemblies can be arranged to regulate height of pipelines to be positioned.

Description

technical field [0001] The invention relates to a positioning device, in particular to a segmental beam prestressed pipeline positioning device. Background technique [0002] The segmental prefabricated assembly method is a construction method in which the beam body of the bridge is prefabricated in segments in the prefabricated field, and then assembled into a whole at the bridge position. Can guarantee and other advantages, the construction method has gradually been widely used at home and abroad. With the development of construction technology, long-span sea and river bridges are gradually being constructed using this method. [0003] The prestressed pipe needs to be preset in the segmental beam. When the segmental beam is prefabricated, the prestressed pipe needs to be positioned. The existing segmental beam prestressed pipe positioning device requires a lot of manual operations, which is troublesome to operate and takes a long time to locate. , reducing work efficienc...
