Description

Automatic butt joint hydraulic machine for PCCP (prestressed concrete cylinder pipe) pipelines

Technical Field

The invention relates to the technical field of hydraulic presses, in particular to a PCCP (prestressed concrete cylinder pipe) automatic butt joint hydraulic press.

Background

In the traditional PCCP pipeline installation, steel cross beams are mainly arranged at an outer opening of a pipeline to be installed and an installed pipeline interface respectively, a chain block and a guide chain (or a steel strand) are adopted to connect the two cross beams, and the pipeline to be installed is pulled into an installed pipeline socket by manually pulling the guide chain to complete the installation of the pipeline. The traditional installation method has low installation efficiency and has the hidden danger that the chain block is broken by chain inversion and hurts people. The chain block is used as an inner tension, so that the problem of uneven tension on two sides is easily caused during pipeline installation, and further, the sealing performance of a pipeline joint is poor and the rework rate is high due to the fact that a rubber ring is extruded; the steel wire rope or the guide chain is used as a connecting piece, and the dead weight of the chain block is added, so that the pendant of the chest expander is large, the installation gap is large, and the installation time is long; when the large-caliber PCCP is installed, 15-20 persons are needed for operation, the personnel investment is large, the construction cost is high, and the production efficiency is low; the chain block and the steel wire rope are both easy-to-wear components, so that the construction cost is increased indirectly; the steel wire rope is used as a flexible connecting piece, and is easy to snap when bearing a large tensile force, so that safety accidents occur.
