Abstract

The utility model relates to a pipeline positioning pedestal and belongs to the field of construction equipment technology. The pipeline positioning pedestal comprises a cooperation portion sleeved in a pipeline opening. One end of the cooperation portion is stuck out of the pipeline and is fixedly connected with a pedestal circular plate. A prism supporting rod is extended from the center of the pedestal circular plate and is coaxial with the cooperation portion. The free end of the prism supporting rod is equipped with an annular groove. The pipeline positioning pedestal has advantages of easy use and high measuring precision.

Description

The location of pipeline base
Technical field
The utility model relates to a kind of location of pipeline base, belongs to the preparation of construction technical field.
Background technology
Along with the development of national economy, more and more higher to the demand of the energy, make Construction of Nuclear Electricity in China, wide development space and development scale arranged.Pipeline is as the link that connects each generating set of nuclear power station, because its quantity in nuclear power construction is many, the locus state is various, cause the center of different angles rigid body pipeline under any vacant state is difficult to the location, can only pass through the measuring channel outer wall at present, by the similarity measure method of wall thickness, internal diameter size inverse pipeline center position, precision is relatively poor, and waste time and energy, poor stability has affected quality and the progress of constructing.
The utility model content
The technical problems to be solved in the utility model is, proposes a kind of easy to use, location of pipeline base that measuring accuracy is high.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of location of pipeline base, comprise the auxiliary section that is placed in pipeline tapping, the auxiliary section is stretched out the outer end of pipeline and is fixedly connected with the base plectane, the center of base plectane extends outward the prism support bar coaxial with the auxiliary section, and the free end of prism support bar is shaped with annular recess.
Preferably, the diameter of base plectane is greater than the external diameter of pipeline.
Preferably, the free end of prism support bar is shaped with chamfering.
Location of pipeline base of the present utility model adopts and coordinates to install the structure of prism with pipeline tapping, and the beneficial effect that has is:
1, the precision of measuring is high, and the prism support bar is coaxial with the base auxiliary section, and the pipeline that namely is mated is coaxial, by the accurate position of measuring channel center line of the prism that is mounted thereon.
2, easy installation and removal, safe, pipeline as long as the location of pipeline base is inserted pipeline, inserts prism on prism supports under any location status, just can measure the three-dimensional coordinate of pipeline center.
3, simple in structure, easy to process, only comprise auxiliary section, base disk and three ingredients of prism support bar, adopt the method for welding to get final product rapid processing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Embodiment one
The part drawing of the location of pipeline base of the present embodiment as shown in Figure 1, comprise the auxiliary section 1 that is placed in pipeline 6 openings, auxiliary section 1 is stretched out pipeline 6 outer ends and is fixedly connected with base plectane 2, the center of base plectane 2 extends outward the prism support bar 3 coaxial with auxiliary section 1, and the free end of prism support bar 3 is shaped with annular recess 4.
During use, the auxiliary section 1 of the location of pipeline base of the present embodiment is inserted in the opening of pipeline 6, because the prism support bar 3 on base plectane 2 is coaxial with auxiliary section 1, namely also coaxial with pipeline 6, prism is installed on prism support bar 3, rear prism also just is on the center line of pipeline 6, be the position coordinates of pipeline 6 center lines after the position coordinates of the prism that the employing all-station instrument accurate measurement obtains, realized the quick and precisely measurement to pipeline 6 positions.
Embodiment two
The location of pipeline base of the present embodiment is the improvement on embodiment one basis, and as shown in Figure 2, its improvements are: the diameter of base plectane 2 is greater than the external diameter of pipeline 1, and the free end of prism support bar 3 is shaped with chamfering 5.
Base plectane 2 greater than pipeline 1 external diameter can so that the location of pipeline base is easier after measuring end be taken off from pipeline, be formed on the free-ended chamfering 5 of prism support bar 3 and make prism more convenient when mounted.
The above is only preferred embodiment of the present utility model, as long as adopt the technical solution of the utility model, perhaps modification or the equivalent variations made based on conventional means on it of those skilled in the art, all drop in the protection domain of the utility model requirement.

Claims (3)

1. location of pipeline base, it is characterized in that: comprise the auxiliary section that is placed in pipeline tapping, described auxiliary section is stretched out the outer end of pipeline and is fixedly connected with the base plectane, the center of described base plectane extends outward the prism support bar coaxial with the auxiliary section, and the free end of described prism support bar is shaped with annular recess.
