Technical field
The utility model relates to a kind of sensor fastening devices.More particularly to a kind of novel pipeline on-line positioned thickness gauging
Sensor fastening device.
Background technique
Traditional pipeline spot thickness measurement is mostly offline manual thickness measuring.There are many drawbacks for manual thickness measuring：
1, thickness measuring data accuracy is poor：Repeatedly craft thickness measuring is difficult to measure on the same point, and measurement comparativity is poor, can only
Measured value is chosen in compromise；Coupling dynamics, the angle difference of hand dipping directly affect the accuracy of measurement data.
2, online high-temperature thickness measuring performance difficulty：Operating difficulties, probe cannot measure on high-temperature pipe for a long time.
3, high-altitude scene thickness measuring performance difficulty：Need to set up scaffold measurement.
4, high temperature and the security risk of high altitude operation are all very big.
In view of offline manual thickness measuring problems, pipeline spot thickness measurement is changed to on-line positioned thickness gauging more at present, is divided into two
Kind pattern：One kind is that pipeline directly welds pattern；Another is anchor ear installation approach.
The direct welding form of pipeline, that is, thickness measurement online sensor fixed bolt and measurement point pipeline directly weld, sensor
It is fixed on pipeline by welding screw, this form causes other problem：When sensor fixed bolt and pipeline weld, to pipeline
Damage is big, and especially the higher high temperature chrome molybdenum steel pipeline of welding requirements, the bad pipeline of welding quality are easy to produce crack, cause two
Secondary accident；Welding is generally required after device is stopped work and is carried out, and the replacement of measurement point position, installation and maintenance is influenced big.
Current anchor ear installation approach is the fixed bolt of the preparatory soldered sensor on anchor ear, passes through steel band or steel plate
It is stuck on pipeline, the method can solve the problem of directly welding pattern, but on-line positioned thickness gauging needs thickness measurement sensor and pipe
Road is in long-term good coupling state.Field pipes vibration is big, expands with heat and contract with cold caused by pipe temperature variation etc. will be to coupling
It directly has an impact, so as to cause measurement inaccuracy or does not acquire measurement data.
Summary of the invention
Technical problem to be solved by the utility model is to provide one kind adjusted by a dedicated spring pipeline with
The swollen deviation of line caused by anchor ear expands with heat and contract with cold, and avoid the novel pipe of defective coupling phenomenon caused by causing to loosen because of pipe vibration
Road on-line positioned thickness gauging sensor fastening device.
Technical solution used by the utility model is：A kind of fixed dress of novel pipeline on-line positioned thickness gauging sensor
It sets, it is described including the upper anchor ear and lower anchor ear for blocking process pipe, and for upper anchor ear and lower anchor ear to be fastened on
Two groups of bolt arrangements on process pipe are provided with sensor base, the middle part of the sensor base on the upper anchor ear
Perforative up and down to be fixedly installed thickness measurement sensor, the both ends of the sensor base respectively pass through a group welding bolt arrangement respectively
It is fixed on the upper anchor ear, the corresponding thickness measurement sensor of upper anchor ear is provided with through hole, the thickness measurement sensor
Lower end is to be of coupled connections with the process pipe through the through hole.
Two groups of bolt arrangements are identical, include：Through pair of upper anchor ear and lower anchor ear side fixed part
Hook bolt, the both ends for being threaded in the stud are used to that anchor ear and lower anchor ear to be made to be fastened on the process pipe
On hex nut, wherein hex nut on the fixed part of the upper anchor ear and between the fixed part of the upper anchor ear
It is provided with Rectangular Spring.
Two groups of bolt arrangements are identical, include the weld bolt that bottom end is welded on the upper anchor ear,
Cover the weld bolt top and be located at the sensor base upper surface on disk spring, and with the welding spiral shell
Bolt threaded upper ends connect the nut for positioning the sensor base.
The novel pipeline on-line positioned thickness gauging sensor fastening device of one kind of the utility model, gets angry without carry out scene
Operation can be installed and be replaced online, and reduction scene is got angry security risk；Thickness measurement sensor fixed bolt and pipeline is avoided to weld
Shi Zaocheng Pipeline damage problem, especially high-temperature pipe；The utility model have automatic tensioning function, avoid because pipe vibration,
Expanding with heat and contract with cold etc. causes to contact defective coupling phenomenon；The utility model installation, maintenance, replacement are convenient, reduce the high vacant duct of high temperature
Operation；Flexibility ratio is high, and favorably the confined space is installed on site.The use process of the utility model is very simple：Directly thickness measuring is passed
Sensor fixed bolt is welded on pipeline hoop in advance, and adjustment anchor ear is to installation point, by pre-tightening anchor ear and thickness measurement sensor
The nut of two sides come guarantee install thickness measurement sensor required by spring tension, thus guarantee thickness measurement sensor contact coupling.This
Utility model can motionless fire behavior condition at the scene, any installation point for adjusting thickness measurement sensor, and guarantee that thickness measurement sensor is long
Phase good contact coupling, is widely used on the process pipes such as petrochemical enterprise.
