Efficient assembly equipment for bridge prestress tensioning equipment

Abstract

The invention discloses efficient assembly equipment for bridge prestress tensioning equipment. The efficient assembly equipment comprises a rack; the lifting table is movably mounted on the rack in a lifting manner; the horizontal movable table is horizontally and movably mounted on the lifting table; the alignment frame is installed on the horizontal movable table, the upper end face of the alignment frame is provided with an arc-shaped alignment plate and an alignment disc installation base, the inner wall of the arc-shaped alignment plate is an arc face and used for supporting and placing a prestress tensioning jack, the alignment disc installation base is used for placing an alignment disc, and the arc-shaped alignment plate is aligned with the alignment disc installation base; and the traveling crane is used for hoisting the prestress tensioning jack to the arc-shaped alignment plate. The steel strands are pre-threaded through the alignment disc, so that the relative position of each steel strand is stable, and then the pre-stress tensioning jack is aligned with the alignment disc to move, so that one-time threading of all the steel strands is achieved; automatic alignment of the prestress tensioning jack and the alignment disc is achieved through the arc-shaped alignment plate and the alignment disc installation base, and operation is convenient.

Description

Technical field [0001] The present invention relates to the field of prestressed tensile construction, in particular to a high-efficiency assembly device for a bridge prestressed bellows. Background technique [0002] At present, the field current pouring bridge prestressed Zhangli needs to be artificially set up a bracket, artificially transported tensile equipment, especially Zhang Leung's top, the jack is relatively heavy, and some areas cannot be effective in effective machinery, so that the construction progress is slow, no safe, and wearing steel When straded, the working anchor is often used for the number of steel stranders, the position is unstable, and the moving jack is difficult to carry all the steel stranded. Inventive content [0003] The present invention is intended to address at least one of the technical problems present in the prior art. To this end, the present invention proposes a high-efficiency assembly apparatus for bridge prestressing tensile devices to...

AI Technical Summary

Problems solved by technology

[0002] At present, the prestressed tensioning of cast-in-place bridges requires manual erection of supports and manual transfer of tensioning equipment, especially tensioning jacks. The jacks are relatively heavy, and effective machinery cannot be used in some areas, which makes the construction progress slow, unsafe, and wears steel. When stranding wires, the installation of working anchors is often difficult due to the large number of steel strands and the unstable position, so it is difficult for the mobile jack to align all the steel strands at one time.
