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

Embodiment 1

[0041] Embodiment 1: During construction, first insert the heads of the two base tubes 1 into the two ends of the installation holes, that is, on the left and right sides of the wall, and then insert the pipes into the accommodating chambers 12 of the two base tubes 1 . Then two correction plate assemblies 3 are respectively capped on the ports at the left and right ends of the pipeline. Turn on the laser total station to determine the installation axis of the pipeline, and turn on the laser total station to emit laser light. Then, the plurality of adjustment limit rods 2 are rotated to push the pipeline to move in multiple directions in the accommodation cavity 12 to adjust the position of the pipeline. For example, when an adjustment limit rod 2 on the left side of the base pipe 1 is tightened clockwise, the adjustment limit rod 2 on the left side gradually extends into the accommodation cavity 12, and gradually pushes the pipeline in the accommodation cavity 12 to the right...

Embodiment 2

[0042] Embodiment 2: The difference from Embodiment 1 is that under certain construction conditions, pipes may have been inserted into the installation holes in advance, and then centered. At this time, the two base tubes 1 can be sleeved on the tubes from both ends of the tubes, so that the tubes can be inserted into the accommodation chambers 12 of the two base tubes 1 at the same time. Then move the two base tubes 1 and insert the heads of the two base tubes 1 into the two ends of the mounting holes respectively; then perform subsequent position adjustment and centering operations.

[0043] Through the above special scientific design, it has the following technical advantages:

[0044] One is the precise centering device of the present invention, which has a simple and compact structure and is easy to process and manufacture. Through the mutual support and mutual cooperation of the base tube 1, multiple adjustment limit rods 2, and two correction plate assemblies 3, it can ...

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...
