Rapid positioning device used during installation of large-pipe-diameter PCCP

Abstract

A rapid positioning device used during installation of a large-pipe-diameter PCCP is composed of a platform framework, a supporting frame and a bearing frame and is mainly composed of angle iron, steel pipes and steel plates. The platform framework is composed of angle iron. The supporting frame is mainly composed of angle iron and steel pipes. The bearing frame is composed of steel pipes and steel plates. The steel pipes are connected through internal threads and external threads, can be freely stretched out and drawn back, and ejects the steel plates in pipe gaps of the PCCP tightly. By means of the positioning device, tubular products can be rapidly positioned in the axis direction, it can be ensured that the tubular products synchronously move forwards, and the device is safe, reliable, effective, high in construction speed, low in manufacturing cost, easy to manufacture, not prone to damage and high in utilization rate, thereby increasing the construction speed and saving cost.

Description

technical field [0001] The invention relates to a fast positioning device for the installation of large-diameter PCCP pipes, especially when the construction work area is narrow, the installation and positioning are difficult, and the construction quality is difficult to guarantee, which directly leads to low installation efficiency of PCCP pipes. Therefore, a positioning device is required. device for quick positioning. Background technique [0002] When installing large-diameter PCCP pipes, after the crane lifts the pipes into place, it is necessary to use conventional methods such as chain reversing to move the pipes to be installed into the pipes in place for installation. Due to the narrow working surface of some pipe grooves and large slopes, And without effective support, the construction personnel need a large number of personnel and consume a lot of time when operating, and it is difficult to guarantee the running speed of both sides of the pipe during synchronous o...
