A precise centering device and centering method for installation of pipes in holes

Abstract

The invention discloses a precise centering device for installation of pipes in holes, which comprises two base tubes, the heads of the two base tubes are respectively inserted into the two ends of the installation hole, and the two base tubes are equipped with accommodating cavity, so that pipes of different diameters can be inserted into the base tube, the peripheral surface of the tail of the two base tubes is provided with a plurality of threaded holes in the circumferential direction, and each threaded hole is equipped with a threaded adjustment limit Position rod; also includes two adjustable size correction plate assemblies, which are used for the two ports of the capped pipe respectively. To adjust the position of the pipeline and fix the limit of the pipeline so that the laser emitted by the laser total station passes through the collimation of the two calibration plate assemblies at the same time. The invention also discloses a centering method. The invention has the advantages of simple and compact structure, easy processing and manufacture, convenient and flexible operation, high centering precision, good stability and strong adaptability.

Description

technical field [0001] The present invention mainly relates to the field of construction equipment, in particular to a precise centering device for installation of pipes in holes, and also to a centering method based on the precise centering device. Background technique [0002] In today's industrial construction and urban construction, a method of operation is involved: that is, first punch a mounting hole on the wall, and then insert a pipe into the mounting hole. After the pipe is centered in place, use cement to place it The pipe is fixed in the mounting hole. There are following technical problems in this construction operation process: [0003] First, with the development of society, the requirements for precise construction are getting higher and higher. However, the current alignment methods of pipelines are primitive and rough (for example, many rely entirely on visual alignment), the alignment time is long, and the alignment accuracy is not high, which cannot ens...

Problems solved by technology

This centering fixing method is very unstable. During the pouring process, the pouring work parts will inevitably touch the pipe, which will cause the original centered pipe to shift again, and then the poured and fixed pipe will not achieve accurate centering.

[0005] Third, in order to overcome the stability problem of the above-mentioned second point, some centering fixtures (such as wooden wedge pads) are used to repeatedly fix the pipeline, and these centering fixtures are blocked between the pipeline and the installation hole, so that The cement pouring operation is not easy to operate, so that the cement pouring inside the installation hole is not in place, which seriously affects the subsequent stability and safety of the pipeline and even the building

Moreover, these centering fixtures are not easy to take out after pouring, and cannot be reused

[0006] Fourth, in existing operations, multiple pipes with different diameters may be installed at the same construction site

Not only does it result in a large number of centering fixing parts and many models, it is not easy to make and carry, but also makes the centering fixing operation cumbersome
