Description

Pipe straightener {pipe straightener}

The present invention relates to a pipe straightening device, and more specifically, to minimize the joint (flange) connection of pipes such as hydraulic lines, power transmission pipes, oil pipelines, gas pipes, etc. to a predetermined length in large industrial sites such as shipyards and semiconductors. The present invention relates to a pipe straightening device that enables a single pipe to be installed in a length of tens/hundreds of meters while reducing cost, and which can quickly perform on-site arrangement required for installation.

Generally, a separate calibration procedure is required to straighten for use with coiled or deformed pipe.

In particular, in the case of a Sus single core pipe used in a control system for shipbuilding, it is difficult to correct only by the manpower of a worker due to the stainless material and plastic coating.

Therefore, at the work site, it goes through the process of making a straight line by tapping and spreading without a jig, but if it is done entirely by hand, there is a problem in that work efficiency decreases and the number of man-hours increases.

In order to solve the conventional problems, Patent Document 1 provides a pipe straightener that can not only straighten a bent pipe and remove concrete at the same time, including a body, a chuck rotating means, an impact member, and a conveying means, but also make pipe straightening more reliable. However, it relates to a pipe straightening device capable of removing concrete adhering to a pipe, and as a device for straightening bent pipes mainly used in construction sites, there is a problem that is not suitable for straightening a suspipe used in shipbuilding.

On the other hand, Patent Document 2 is a body portion provided with a driving device; a pipe supply unit provided on one side of the body unit, on which a pipe drum around which pipes are wound is seated to continuously supply pipes; a guide portion provided on the front of the upper surface of the body portion and guiding the pipe to move it backward; A moving unit installed at the rear of the guide unit, having a plurality of rollers having a distance between them and guiding the pipe in, and moving the pipe backward; A horizontal correction unit installed at the rear of the guide unit and provided with a plurality of rollers along the horizontal surface of the path of the pipe to correct the bending on the horizontal surface of the pipe; and a vertical straightening unit installed behind the horizontal straightening unit and provided with a plurality of rollers along the vertical surface of the path of the pipe to correct the bending on the vertical surface of the pipe. pipe was provided.

However, Patent Document 2 has a problem in that efficiency is reduced due to cost increase as movement efficiency to the required work site is reduced because it constitutes a vertical correction unit and a horizontal correction unit in one body.
