↵Rail Fishplate Fastening System

Ib lub tsheb ciav hlau Fishplate, lub npe hu ua kev sib koom ua ke lossis splice bar, yog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau sib koom ua ke tsim los txuas ob txoj kev tsheb ciav hlau uas nyob ib sab kawg ntawm lub pob tw. Feem ntau yog tsim los ua ib khub ntawm cov hlau tuav, lawv tau bolted ruaj khov rau hauv lub vev xaib ntawm cov ntsia hlau ntawm ob sab, hla qhov sib txawv ntawm txoj kev tsheb ciav hlau. Lawv lub luag haujlwm tseem ceeb yog xa mus rau lub sijhawm khoov thiab lub zog shear hla kev sib koom ua ke, tswj kev tsheb ciav hlau thiab kev txuas ntxiv thaum tso cai rau kev tswj xyuas thermal expansion. Fishplates yog engineered kom phim cov rail profile precisely thiab yog ib qho tseem ceeb rau kev tswj txoj kev ncaj ncees nyob rau hauv qhov chaw uas tsis tu ncua welded rail (CWR) tsis siv, xws li ntawm insulated pob qij txha, expansion pob qij txha, thiab nyob rau hauv ib ntus los yog kho scenarios.

Functional & Engineering Perspective

Kev ntsuam xyuas hnav thiab deformation:Kev tshuaj xyuas rau kev hnav ntawm cov kabmob qhov chaw tiv thaiv lub vev xaib tsheb ciav hlau, deformation (bending) ntawm daim hlau, thiab elongation lossis "ovaling" ntawm lub qhov ntsia hlau, uas qhia tias muaj ntau lub load thiab yuav tsum tau hloov.

Insulated Joint Integrity Checks:Rau insulated fishplates, kev saib xyuas suav nrog kev tshuaj xyuas cov khoom tawg lossis degraded insulating Cheebtsam, kuaj cov hluav taws xob tiv thaiv, thiab xyuas kom tsis muaj hlau-rau-hlau tiv tauj tsim ib qho kev taw qhia luv luv.

Kev tiv thaiv kev hloov pauv raws li kev thauj mus los:Fishplates nyob rau hauv mainline cov kev pab cuam feem ntau yog hloov nyob rau hauv ib tug tiv thaiv lub sij hawm raws li nyob rau hauv cumulative Megatonnes (MGT) ntawm lub tsheb, raws li lub neej qaug zog yog zoo sib xws nrog load cycles, txawm ua ntej pom cov kab nrib pleb.

Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm

Qhov Drilling thiab Counterboring Precision:Bolt qhov chaw yog drilled nrog high precision los xyuas kom meej kev sib raug zoo ntawm ob daim hlau thiab cov tsheb ciav hlau pre-drilled qhov. Counterbores yog machined kom haum rau lub taub hau ntsia liaj qhov rooj thiab cov txiv ntseej nrog los yog hauv qab ntawm lub phaj nto.
Khoom Qib thiab Toughness Specification:Ua los ntawm nruab nrab -carbon lossis micro- alloyed steel nrog cov ntsiab lus tawm los thiab cuam tshuam cov khoom muaj zog, feem ntau dhau ntawm lub hauv paus rail steel lub toughness kom ntseeg tau tias qhov sib koom ua ke tsis yog qhov sib txuas tsis muaj zog tshaj plaws.
Thaum tshav kub kub kho rau Durability:Nyob rau hauv kev tswj quenching thiab tempering kom ua tiav qhov zoo tshaj plaws hardness profile- nyuaj txaus los tiv thaiv hnav thiab deformation ntawm cov ntsia liaj qhov rooj qhov thiab cov kabmob nto, tseem tawv txaus los tiv thaiv kev puas tsuaj.
