Embodiment Construction

[0020] The present invention is described in detail below in conjunction with the examples, and the purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0021] see figure 1 , this pipe installation center positioning device adopts a three-jaw chuck structure, and its main part is a positioning disc 1, which is a φ50 disc made of steel plate. A center hole 7 is arranged in the middle of the positioning disc 1, and the positioning circle Three jaws 2 are connected around the disk 1, and the scale line on the jaws 2 is subdivided. There is a long slot 6 in the center of the jaw 2, and a movable positioning pin is embedded in the long slot 6. The positioning pin is a bolt structure. 4 passes through the long slot 6 on the claw 2 and is positioned on the claw 2 by the lock nut 3, and the upper part of the nut of the bolt 4 is vertically fixed with a positioning plate 5...

Abstract

The invention relates to a centralized positioning device and a positioning method thereof for aligning the center of a pipe and the center of a preformed hole when the pipe is installed. The centralized positioning device comprises a positioning disc and clamping jaws, wherein a center hole is formed in the center of the positioning disc, clamping jaws which are radially and uniformly arranged are fixed at the periphery of the disc, and each clamping jaw is provided with scales and a movable positioning pin. When the centralized positioning is performed, the centralized positioning device is fixed in the preformed hole of a wall, and the positioning disc of the centralized positioning device is located in the center of the preformed hole; a straight pipe is inserted from the center hole of the positioning disc, a level gauge is arranged on the straight pipe, after a pipe to be hoisted has a horizontal relationship with the straight pipe, the parallel position deviation of the pipe to be hoisted and the straight pipe is directly measured, the height of the pipe to be hoisted is calculated, and the centralized positioning of the pipe is finished. The centralized positioning device is adopted to finish the alignment of the pipe center, the operation is quick and simple, the crowding phenomenon caused by more installation staffs is avoided, and the pipe installation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a method for installing a pipeline through a wall or an overhead pipeline, in particular to a center positioning device and a positioning method for aligning the center of a pipeline and the center of a reserved hole during pipeline installation. Background technique [0002] In the pipeline installation construction, when the pipeline passes through the wall or the overhead pipeline is connected with the fixed pipe fitting, it is necessary to align the center of the hole or the fixed pipe fitting in advance. The traditional leveling method adopts the conventional leveling method, which requires a long working time, and it is impossible to build a measurement platform due to conditions. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems of pipeline center alignment in existing pipeline installation and construction, and provides a pipeline installation center positioning device...
