Abstract

The invention belongs to the technical field of construction equipment and relates to prestressed pipe pile automatic tensioning equipment. The prestressed pipe pile automatic tensioning equipment provided by the invention comprises a base. A hydraulic station, a control console, a mobile lifting platform, a tensioning machine floating device, a tensioning butting locking device, a cylinder nut automatic tightening device and a pipe pile nut automatic tightening device are mounted on the base. The mobile lifting platform can move front and back on light rails of the base. The tensioning machine floating device is fixedly mounted on the mobile lifting platform and can move up and down or hover. The cylinder nut automatic tightening device, the tensioning butting locking device and the pipepile nut automatic tightening device are all mounted on the tensioning machine floating device and can move front and back along the same center line. The prestressed pipe pile automatic tensioning equipment can automatically realize pipe pile prestress tensioning and is high in automation integration degree and butting precision and capable of effectively reducing the probability of occurrence ofaccidents and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an automatic tensioning equipment for multi-type prestressed pipe piles. Background technique [0002] At present, concrete pipe piles, as a cement product, are widely used in various infrastructure engineering fields. Prestressed tensioning is an important production link of concrete pipe piles. Its function is to apply pre-tension stress to the internal steel cage before the concrete pipe piles bear the external load, so as to improve the bending resistance and stiffness of the pipe piles and delay The time for cracks to appear increases the durability of concrete pipe piles. [0003] At present, in the production process of pipe piles, the tensioning is mainly carried out by manually operating the tensioning machine. The detailed steps are: 1. The equipment moves the pipe pile mold to the tensioning position, and manually inserts the nut auxiliary gear and the ...
