Description
Technical field
The present invention relates to pipeline inspection technology fields, specially based on the Concentricity tolerance monitoring device of pendulum method.
Background technique
Heating network and water supply network the junction of pipeline can because pipeline expand with heat and contract with cold or the shadow of other external force
It rings, leads to that Concentricity tolerance occurs between pipeline, when deviation is excessive, will cause pipeline junction leakage, the attached of pipeline sets
Standby damage, and the detection of existing pipeline concentricity is mainly radially monitored by radial multipoint resistance type monitoring, current vortex sensor
Deng, and the structure of radial multipoint resistance type monitoring is relative complex, is not suitable for doing non-cpntact measurement；The monitoring of current vortex sensor is inclined
It is small to move range, is not suitable for the on-line monitoring of pipeline
Hot duct uses metal structure more, and pipeline transmission medium is mostly hot water, the expansion and contraction property of pipeline, and hot water makes pipeline
It expands and compensator is driven to do telescopic displacement, because there is the trueness error of installation, it cannot be guaranteed that two pipes being connected
The center in road is absolutely consistent, can be with the Concentricity tolerance between two pipelines in thermal expansion, and Concentricity tolerance is excessive and surpasses
It can cause pipeline breaking, compensator damage etc. when piping load, cause pipe leakage accident；And at pipeline turning, heat expansion
Shrinkage influences the telescopic displacement of pipeline bigger, and due to Impact direction difference, the phenomenon that Concentricity tolerance is easier to occur.
Summary of the invention
The purpose of the present invention is to provide the Concentricity tolerance monitoring devices based on pendulum method, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the present invention provides the following technical solutions：Concentricity tolerance monitoring device based on pendulum method,
Including the transmission guide rod being mounted in first pipe, and the rotating stand being mounted on second pipe, the transmission guide rod
The other end slidably connects the swing rod being arranged on rotating stand, is equipped on the swing rod and slides vertically for detecting transmission guide rod
The linear displacement detecting sensor of offset is moved, is equipped on the rotating stand for detecting swing rod along second pipe circumferential direction
The angle/placement detection sensor of deviation angle.
The guide hole mobile for transmission guide rod vertical direction is offered on the swing rod.
The first fixed bracket for being fixedly connected with transmission guide rod, and the first fixed bracket are installed in the first pipe
It can circumferentially rotating along first pipe.
The second fixed bracket for being fixedly connected with rotating stand, and the second fixed bracket are installed on the second pipe
It can circumferentially rotating along second pipe.
As shown from the above technical solution, the present invention by can vertical displacement and along pipeline circuit oscillation transmission guide rod come real
Now to the real-time monitoring of pipeline offset, and design structure is monitored suitable for pipelines, is easily installed simultaneously.
Detailed description of the invention
Fig. 1 is scheme of installation of the present invention；
Fig. 2 is swing rod structure schematic diagram of the present invention；
Fig. 3 is inventive pipeline offset function relation figure.
In figure：1 first pipe, 2 sealing rings, 3 second pipes, 4 second fixed brackets, 5 first fixed brackets, 6 transmissions are led
Bar, 7 swing rods, 8 rotating stands, 9 guide holes, 10 linear displacement detecting sensors, 11 angle/placement detection sensors.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing：
Concentricity tolerance monitoring device based on pendulum method as shown in Figs. 1-2, by sealing ring 2 by first pipe 1 when installation
It is tightly connected with second pipe 3, and guarantees that the position of first pipe 1 and second pipe 3 is horizontal, and Concentricity tolerance is zero,
Transmission guide rod 6 is equipped with by the first fixed bracket 5 and the second fixed bracket 4 respectively in first pipe 1 and second pipe 3 and is turned
Dynamic support 8, and the other end of transmission guide rod 6 is arranged in the guide hole 9 for upper and lower displacement, transmission guide rod 6 and swing rod 7 are vertically set
It sets, the angle/placement detection sensor 11 for swing rod 7 along the circuit oscillation of second pipe 3 is installed on rotating stand 8.
When the Concentricity tolerance of vertical direction occurs, transmission guide rod 6 can move up and down in guide hole 9, can't occur
The angular displacement of swing rod 7；Transmission guide rod 6 can be detected by linear displacement detecting sensor 10 along 9 straight-line displacement of guide hole and be calculated,
And the angle that angle/placement detection sensor 11 detects is zero, the Concentricity tolerance occurred at this time can be inclined upwards according to Y direction
Difference and the downward deviation of Y direction calculate, as shown in Figure 3.
When the Concentricity tolerance on nonumeric direction occurs, swing rod 7 not only can along 9 straight-line displacement of guide hole, while
It will drive swing rod 7 and generate angular displacement, straight-line displacement is calculated by the detection of linear displacement detecting sensor 10, and angular displacement is by angle position
The detection of detection sensor 11 is moved to calculate；
A is the home position that Concentricity tolerance is zero；
Location of C：Assuming that first pipe 1 shifts to the right, cause the Concentricity tolerance of first pipe 1 and second pipe 3, straight line
The distance that displacement detecting sensor 10 can measure OC is L, and angle/placement detection sensor 11 can be with the deviation angle of measuring oscillating bar 7
For θ, according to the parameter of trigonometric function total Y1, X1；
Y1=L×sinθ；
X1=L×cosθ;
It is X1 and Y1-Y0 that relative to A point concentric offset, which occurs, for C point;
The position D：Assuming that first pipe 1 shifts to the right and downwards, cause first pipe 1 and the concentricity of second pipe 3 inclined
Difference, the distance that linear displacement detecting sensor 10 can measure OD is L, and angle/placement detection sensor 11 can be with measuring oscillating bar 7
Deviation angle is θ, according to the parameter of trigonometric function total Y2, X2；
Y2=L×sinθ；
X2=L×cosθ;
It is X2 and Y2-Y0 that relative to A point concentric offset, which occurs, for C point;
Similarly, it is assumed that first pipe 1 is to the left, to the left and when shifting upwards, can also calculate the offset of opposite X, Y.
It originally is that embodiment uses transmission guide rod 6, swing rod 7 and rotating stand 8 to be arranged at first pipe 1, second pipe 3
Top, in actual use, transmission guide rod 6 can be rotatably installed in the underface of first pipe 1, pendulum by the first fixed bracket 5
Bar 7 and rotating stand 8 can be rotatably installed in the underface of second pipe 3 by the second fixed bracket 4, and using effect is identical.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
