Unogona Kudhiraivha Railroad Rail? - A Complete Safety & Technique Guide

Kuchera muzvikamu zvenjanji - ingava njanji, matai, masipikisi, kana masimbi ari pedyo - ibasa rinowanzogadziriswa, asi rinoda kunyatsojeka, maturusi akakodzera, uye kuteedzera kuchengetedzeka nemitemo yemutemo. Zvikaitwa zvisiri izvo, zvinogona kukanganisa kutendeseka kwechimiro kana kutyora mutemo wemubatanidzwa. Mugwaro rino, tinotyora sainzi, nzira, uye mirau iri seri kwezvikamu zvenjanji - kuitira kuti uzviite zvisina njodzi, zviri pamutemo, uye nemazvo.

1. Unogona Kudhiraivha Railroad Rail? - Nzira Yakarurama

Kuchera kuburikidza nenjanji ibasa rakasarudzika rinowanzoitwa panguva yekugadzirisa kana kuvaka. Zvinoda kushandiswa kwemichina inorema-uye kutevedzera mitemo yekuchengetedzwa kwakasimba. Iyo nzira inosanganisira:

Kumaka iyo Drill Nzvimbo: Kuyera kwakaringana kunotorwa kuve nechokwadi kuti gomba rakadhirwa munzvimbo chaiyo. Kusarongeka kunogona kutungamirira kukusagadzikana kwepfungwa uye kukundikana kwenjanji nguva isati yakwana.
Kushandisa Specialized Equipment: Chibooreso chenjanji, chakanyatsogadzirirwa chinangwa ichi, chakakosha. Madhiri aya anobata ukobvu hwakanyanya nekuoma kwesimbi yenjanji - kazhinji inodarika 350 HB (Brinell Hardness).
Kutonhodza uye Kuzora: Kupisa kwakanyanya kunogadzirwa panguva yekuchera kunogona kuvharira simbi kana kudzima zvishoma. Masisitimu anotonhodza (kazhinji oiri-yakavakirwa kana kuti akagadzirwa) anosungirwa kuchengetedza zvinhu zvesimbi. Dzidza zvakawanda kubvaASM International's Machining Data Handbook.
Post-Kuongorora Kuchera: Mushure mekucherwa, njanji dzinofanirwa kutariswa nekuona uye neultrasonically kuona madiki{{0}kutsemuka kana deformation. TheUS Federal Railroad Administration (FRA)inoraira izvi kune vese Kirasi I njanji.

2. Ndeipi Giredhi reSimbi iRailroad Track?

Njanji dzenjanji dzakagadzirwa kubva kugiredhi chaiyo yesimbi inozivikanwa sesimbi yenjanji - yakagadziridzwa kuti igare yakasimba zvakanyanya pasi pekuiswa mabhasikoro. Magiredhi akafanana anosanganisira:

AISI 1085: Yakakwirisa{{0}kabhoni simbi (~0.85% C) inopa kusakara kwakanaka uye kuoma. Yakanakira-mitsara yekutakura zvinhu zvinorema.
UIC60: YeEuropean standard njanji mbiri uye simbi giredhi, inozivikanwa nekuyema kwayo kwesimba, kuomarara, uye kuramba kune rolling kuonana kuneta.

Aya mamakisi anosarudzwa kuti amirire mitoro yeaxle inodarika matani makumi matatu uye mamirioni ekutenderera kwekushushikana. Kuti uwane kutsanangurwa kwezvinhu, tarisa kuneISO 500-1:2022 - Zvishandiso zveNjanji - Njanji.

3. Hazvitenderwi Kuisa Zvinhu Panjanji?

Hongu - kuisa zvinhu panjanji hazvisi pamutemo munzvimbo dzese. Izvi zvinosanganisira mari, zvinhu zvako, kana midziyo yekuchera isina mvumo. Sei?

Zviri afederal mhosvapasi peUS Code Title 49, yakasimbiswa neFRA.
Inoisa pangozi vashandi vezvitima, vafambi, uye veruzhinji.
Inogona kukonzera kuparara, kudhura mamiriyoni uye kuisa upenyu pangozi.

TheNational Transportation Safety Board (NTSB)inoongorora zviitiko zvese zvekukanganisa track. Gara uchibatana nevakuru vezvitima usati washanda chero pedyo nemitsetse inoshanda.

4. Unogona Kudhiraivha muSimbi Railing?

Hongu - asi maitiro ane basa. Simbi njanji padyo nenjanji (semuenzaniso, zvipingamupinyi zvepuratifomu, mabhuraketi echiratidzo) kazhinji anogadzirwa kubva kualuminium, simbi yakapfava, kana simbi inopfurwa. Kuboora zvakachengeteka:

Sarudza Right Drill Bit: Shandisa HSS (Yakakwira-Simbi Yekumhanya) kana kuti carbide-tip bits. Nesimbi isina tsvina, shandisa cobalt-mabhiti arumwe.
Chengetedza Railing: Batanidza kana simbisa iyo workpiece - vibration inogona kukonzera kutsvedza kana kukuvara.
Isa Chiedza Chekumanikidza: Tanga pakaderera RPM, zvishoma nezvishoma wedzera kumhanya. Rega chidimbu chichekwe - usachimanikidza. Kupisa zvakanyanya kunogona kukanganisa hasha. Kuti uwane maitiro akanaka, onaNIST's Engineering Laboratory Guidelines.

5. Best Drill Bits yeTies & Spikes

Railroad Ties (Vakarara):

Wooden Ties: Standard twist drill bits (HSS) inoshanda zvakanaka. Shandisa brad-mapoinzi mabhiti kumakomba anochenesa.
Concrete Ties: Shandisa SDS-pamwe chete masonry bits kana diamond-tipped core bits. Kutonhora kwemvura kunokurudzirwa kuderedza guruva uye bhiti kupera.

Railroad Spikes:

Maspikes ane nyaya-yakaomeswa - yakaoma zvakanyanya pamusoro.
Shandisasolid carbide micro -zvibhoraniine peck drilling uye yekucheka fluid.
Gara uchisunga spike zvakachengeteka. Nezvezviyero zvekusarudza zvishandiso, bvunzaANSI B94.11M - Drill Bit Standards.

Mhedziso

Kudhirowa njanji - njanji, matai, masipikisi, kana njanji - haisi chirongwa cheDIY. Zvinoda ruzivo rwezvishandiso, midziyo yakakodzera, matekiniki ekutonhodza, uye pamusoro pezvose, kutevedzera zviri pamutemo. Kunyangwe iwe uri vashandi vekuchengetedza track kana kondirakiti, kutevedzera aya madhiraivha mashanu kunovimbisa kuchengetedzeka, hupenyu hurefu hwezvivakwa, uye kuomerera kumazinga einjiniya epasi rose. Usambofa wakakanganisa pane chaiyo kana protocol - hupenyu uye zvivakwa zvinoenderana nazvo.
