Description
Technical field
The utility model relates to the technical fields of calibration system, more particularly, to examination wind apparatus on-line calibration system.
Background technique
Train, i.e., vehicle group in column, is divided into two major classes type, railroad train: i.e. train, this is gross morphology.Road train:
Column automobile, automobile group column, highway car group body are organized, has the Mine haul vehicle group of Australia, there is the intelligence rail train of China.
Train is most important traffic machine tool in human history, and early stage is known as steam locomotive, is also train.There is independence
Rail running.Railroad train presses load object, can be divided into the lorry of cargo transport and the car of carrying；Also both there is together passenger-cargo
Vehicle.Numerous continuous vehicles.Refer generally to train, is espespecially hung in column by the company that the compartment of traction locomotive and cargo transport or carrying forms
Train.Train definition: train refer to because certain purpose with hang over a train of vehicles together.It is different from car team.Form train
Vehicle be divided into locomotive and vehicle, the effect of locomotive is power to be provided for train, and the effect of vehicle is to realize the function of train.
EMU is also train.Locomotive and vehicle are not distinguished in train, and a smallest complete functional unit is only regarded as a permutation
Vehicle.Then corresponding train is different for railway types difference.Lu Tie (land surface railway), subway, empty iron (empty iron train), Ba Tie；Lu Tiefen
For heavy rail.Lu Tie heavy rail be railway starting type and consistent mainstream, corresponding train, Train be divided into general fast train,
Rapid series, bullet train (CRH) series, these concepts are divided into narrow sense broad sense, with three-level Chinese Railway (general iron, fastly
Iron, high-speed rail) it is not corresponding relationship.
Train will receive very big wind-force in the process of running, now for the calibration of examination wind apparatus, using will be in pipeline
Portion's sensor disassembles the mode for carrying out measurement and calibration.It needs to disassemble sensor carry out measurement and calibration, there is equipment event
The risk of situations such as barrier or seal failure, and a steady pressure environmental condition can not be provided.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides examination wind apparatus on-line calibration system
System solves the problems, such as to need removal sensor in examination wind apparatus pressure measurement calibration.Working efficiency is improved, disassembly is avoided to influence to set
Standby leakproofness.
The technical solution of the utility model is: examination wind apparatus on-line calibration system, wherein including standard, examination wind fixture,
Portable heating pressure device, pipeline；
Pipeline one end connection examination wind fixture, the other end connect portable heating pressure device, and the examination wind fixture is also
Connect standard.
In the utility model, the purpose for trying wind is safety in order to guarantee train operation.In order to effectively prevent train Fang Yang
The generation of accident.The maintenance calibration situation of test monitoring device is the important link of column inspection work.
In the utility model, examination wind fixture can be connected with examination wind apparatus, measure pipeline internal pressure force signal by standard.
Pressure condition is stablized in the control calibration of portable heating pressure device.
Further, the examination wind fixture include jig main body, set on jig main body top through-hole, be set to fixture master
The interconnecting piece of body lower part.
In the utility model, jig main body is the column structure of strip, and the through-hole on top is connected with examination wind apparatus.And
Described interconnecting piece one end connects standard, other end connecting pipe.The inside of jig main body is the communicating structure of cavity, gas
It can be flow in jig main body from interconnecting piece.
Further, the pipeline is hose.The adaptability of hose is preferable, can facilitate the installing and dismounting of calibration.
Further, the through-hole is circular through hole.Circular through hole can facilitate and the connection that tries wind apparatus.
Compared with prior art, beneficial effect is: the utility model can carry out measurement and calibration to examination wind apparatus pressure, mention
High working efficiency avoids disassembly from influencing equipment leakproofness.It realizes examination wind apparatus on-line metering calibration, tries in wind apparatus calibration process
Pressure regulation provides a stable pressure environment.
