146m is linked together by 12 section steel pipes by ring flange, and the alignment formed between 12 section steel pipes of vacuum tube is pacified in construction
Error is certainly existed during dress, such as: during 1. carrying out vacuum test, air pressure may result in vacuum tube production
Change shape, this will lead to each section short tube and shifts, and may cause the center of circle of each round tube not point-blank；2. steel pipe
In process, there is also certain errors for machining accuracy, that is, there are problems that the straightness error of vacuum tube.In order to verify vacuum
Whether pipeline respectively saves point-blank needs the concentricity to each section vacuum tube center of circle to measure, to analyze each section vacuum
The size of pipe center of circle off-axis.
Utility model content
The utility model provides a kind of detection device for measuring circular pipe concentricity, for the coaxial of circular pipe
Degree is detected.
In order to solve the above technical problems, the technology employed by the present utility model is
A kind of detection device measuring circular pipe concentricity, the central circular including prism can be placed；Multiple telescopic rods
It is set to central circular in the radial direction evenly dispersedly；One end of telescopic rod is fixedly connected on the outer surface of central circular, separately
One end is connected with the contact pedestal for being against inner wall of the pipe；Same position in telescopic rod is equipped with the ranging unit of infrared distance sensor
Part, and the directions of rays of infrared distance sensor is parallel with the axis direction of telescopic rod；The contact pedestal is equipped with for infrared
The through-hole that the ray of distance measuring sensor passes through.
According to above scheme, the telescopic rod includes outer bar and interior bar；One end of outer bar is fixedly connected on central circular
Outer surface, interior bar are inserted into from the other end of outer bar and can be free to slide in outer bar；Outer bar is equipped with the spiral shell for locking interior bar
Nail；The distance member of the infrared distance sensor is set in outer bar.
According to above scheme, the contact surface of the contact pedestal and inner wall of the pipe is the circular arc to match with inner wall of the pipe
Face.
Compared with prior art, the utility model has the beneficial effects that simple structure, versatility are good, installation requirement is low, make
With easy to operate, cooperation total station survey can obtain the three-dimensional coordinate in the circular pipe center of circle, analyze and provide for its concentricity
Accurate data basis.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure
Are as follows: central circular 1, outer bar 2, infrared distance sensor 3, interior bar 4 contact pedestal 5.
The utility model includes that 1, three angle of circular metal central circular that can inlay master prism is mutually 120
Degree and the Telescopic metal bar of retractable, the infrared distance sensor 3 that is mounted in telescopic rod and arc-shaped contact bottom
Seat 5.
Specifically, telescopic rod is connected to the outer surface of central circular 1 evenly dispersedly.One end of telescopic rod is along central circular
1 radial direction is welded in the outer surface of central circular 1, and the other end of telescopic rod is welded with the contact pedestal 5 for being against inner wall of the pipe.It connects
The contact surface for bottoming out seat 5 and inner wall of the pipe is the arc surface to match with inner wall of the pipe, to improve contact stabilization and precision.It stretches
The distance member of infrared distance sensor 3, and the axle center of the directions of rays of infrared distance sensor 3 and telescopic rod are equipped in contracting bar
Direction is parallel.The contact pedestal 5 is equipped with the through-hole passed through for the ray of infrared distance sensor 3.
The telescopic rod includes outer bar 2 and interior bar 4, and outer bar 2 and interior bar 4 are stainless-steel seamless pipe, the internal diameter of outer bar 2
It is identical with the outer diameter of interior bar 4.One end of outer bar 2 is fixedly connected on the outer surface of central circular 1, the other end of the interior bar 4 from outer bar 2
Insertion and can be free to slide in outer bar 2.Outer bar 2 is equipped with the screw for locking interior bar 4.The infrared distance sensor 3
Distance member be set to outer bar 2 in, the other component of infrared distance sensor 3 is then installed on outside outer bar 2, three outer bars 2
The distance member of interior infrared distance sensor 3 is set to identical position, i.e., each infrared distance sensor 3 is and center circle
The circle center distance of ring 1 is equal.
When using the utility model, user first holds telescopic rod, so that one of telescopic rod is located at vertical direction and incites somebody to action
The contact pedestal 5 of its bottom is against inner wall of the pipe, and then equal proportion extends the interior bar 4 of three telescopic rods, makes three 4 ends of interior bar
Contact pedestal 5 be close to inner wall of the pipe.Due to 120 degree of angles each other between three telescopic rods, then when three contact pedestals 5 are equal
When being close to inner wall of the pipe, the center of circle of central circular 1 is meant that when the center of circle of preceding pipeline.Use the infrared of infrared distance sensor 3
The distance between the measurement of flight time distance measuring method and inner wall of the pipe, range measurements change with the collapsing length of interior bar 4,
As the result is shown on external display or computer.If the machining accuracy of circular pipe is good, three infrared distance sensors 3
Reading should be identical.Measurement is placed in the center of central circular 1 with master prism, sets up a whole station in orbit
Instrument can measure the centre coordinate of circular pipe by the position of measuring prism.
Behind the pipeline center of circle for having measured a position, mobile the utility model repeats the above steps, can measure pipeline
Multiple sections central coordinate of circle, later by interior industry handle the concentricity of circuit orbit can be analyzed.
