Mu buryo bw'icyuma bugezweho, imashini zitwara imizigo zimeze nk'amaboko atagira umuvuduko, zitwara akazi gakomeye ko gucunga ibikoresho. Nk'"aho imashini nini" ikorera, imikorere y'impeta zitwara imizigo zikoresha insinga ifitanye isano itaziguye n'imikorere myiza n'umutekano wa crane. Uhuye n'ubwoko bwinshi bw'impeta zitwara imizigo ku isoko, ni gute wahitamo "umufatanyabikorwa w'izahabu" ukwiye crane? Binyuze muri iyi nkuru, tuzagufasha gusubiza ibibazo biri mu mutwe wawe.
Ⅰ. Sobanura imikorere y'imashini zikora (cranes) kandi umenye icyerekezo cyo kuzihindura
Hari abanyamuryango benshi mu muryango wa crane, kandi gantry cranes, broad cranes, na tower cranes buri imwe ifite "umwihariko wayo". Gantry cranes ni nk'"ibihangange by'icyuma" mu bikorwa bya "terminals" z'ibyambu n'ububiko bunini bw'ibikoresho, zigenda hagati y'amakontenari n'imizigo buri munsi. Ntabwo zigomba guhangana n'imitwaro myinshi yo guhaguruka no kugwa kenshi, ahubwo zigomba no kurwanya isuri ry'umunyu n'umukungugu utwarwa n'umuyaga wo mu nyanja, ndetse no "kubatizwa" kw'imvura itunguranye; tower cranes ni "Optimus Prime" aho bubaka. Uko hasi hakomeza kwiyongera, zigomba gukora kenshi ibikorwa byo guterura, kuzunguruka no gukurura, kandi buri kuzunguruka biherekezwa no gutigita gukomeye n'ingaruka. Ibi bintu bidasanzwe bikora bigaragaza ko bifite ibisabwa bitandukanye cyane ku rwego rwo kurinda, ubushobozi bwo gutwara imizigo no kuramba kw'impeta yo gusimbuka y'insinga. Kubwibyo, mbere yo guhitamo impeta yo gusimbuka, iperereza ryimbitse kandi rirambuye ku hantu crane ikorera, inshuro ikora, n'imiterere y'imizigo ni nko gushushanya "ikarita yo kugenzura" nyayo kugira ngo hamenyekane ibindi bizakurikiraho.
Ⅱ. Ibande ku bipimo by'amashanyarazi kandi ukomeze umutekano mwiza w'amashanyarazi n'amashanyarazi
(I) Ibipimo by'ubu
Ubushobozi bwo gutwara umuriro ni cyo kimenyetso cy’ingenzi cy’impeta y’amashanyarazi. Muri rusange, kuri cranes nto z’amashanyarazi zikora akazi ko gukurura umuriro, amashanyarazi angana na 50-100A ashobora kuzuza ibisabwa by’ibanze mu mikorere; mu gihe kuri cranes nini zo mu muhanda, bitewe n’imbaraga nyinshi za moteri itwara, moteri itwara trolley, na moteri itwara trolley, amashanyarazi asabwa ni 200-630A. Iyo amashanyarazi nyayo y’impeta y’amashanyarazi arenze agaciro kagenwe igihe kirekire, ubushyuhe bw’ibice bitwara amashanyarazi buziyongera. Urugero, kuri brushes z’umuringa, iyo ubushyuhe burenze 80°C, amashanyarazi yayo aragabanuka, ubushobozi bwo guhangana na yo buriyongera, kandi ibishashi by’amashanyarazi bishobora guterwa no kwangirika kw’amaburashi n’impeta zitwara amashanyarazi.
(II) Ibipimo by'amashanyarazi
Ingufu zisanzwe zikoreshwa kuri cranes ni 380V, 400V, 690V, nibindi. Mu rwego rw'inganda, amashanyarazi ahinduka hagati ya ± 10%, bityo impeta ihindagurika igomba kugira ubushobozi bwo guhindura amashanyarazi. Urugero, cranes zikoreshwa mu nganda zikora ibyuma zifite uburyo bwinshi bwo guhuza imikorere. Ni ngombwa guhitamo impeta ihindagurika ifite voltage ya 690V ifite ubushobozi bwo kurinda surge, ishobora kwihanganira impanuka ya voltage ihita yikuba inshuro 1.2 kugira ngo ihamye ko umuriro uhoraho.
(III) Ubudahangarwa bw'ubushyuhe n'imbaraga zihangana n'amashanyarazi
Ubudahangarwa bw'amashanyarazi bugaragaza imikorere y'amashanyarazi y'impeta inyerera, muri rusange isabwa kuba iri hejuru ya 500MΩ; ikizamini cy'amashanyarazi yo kwihanganira amashanyarazi kigomba kuba gifite voltage ya 1500V, kandi ntihagomba kubaho kwangirika cyangwa gushya mu gihe cy'umunota 1 kugira ngo impeta inyerera ikore neza mu buryo butekanye mu kirere cy'amashanyarazi kigoye.
Ⅲ. Uruvange rw'impeta ipfundikiye n'ibipimo by'insinga
Isano iri hagati y'impeta y'insinga n'insinga ni nk' "ibikoresho n'umunyururu". Ni mu bufatanye bwa hafi gusa, imikorere myiza ishobora kugerwaho. Mu guhitamo impeta y'insinga, umurambararo w'inyuma w'insinga, umubare w'impeta n'ibikoresho ni byo by'ingenzi. Umwobo w'impeta y'insinga ugomba kuba munini kuri mm 1-2 ugereranije n'umurambararo w'inyuma w'insinga kugira ngo insinga zishyirwemo neza; umubare w'imiyoboro ugenwa hakurikijwe umubare w'impeta y'insinga, kandi muri rusange imiyoboro 1-2 y'insinga irahari.
Ku nsinga zo kugenzura zifite ibice byinshi, niba ubuso bw'ibanze ari 0.75-2.5mm², ubushobozi bwo guhangana n'impeta zinyura bugomba kugenzurwa muri 50mΩ kugira ngo hamenyekane ko uburyo bwo kohereza ikimenyetso budahinduka. Dufashe urugero rw'insinga ya YC ifite umugozi ukomeye, ikunze gukoreshwa mu guhuza moteri ya crane. Ubusanzwe umurambararo wayo ukubye inshuro 6-8 z'umurambararo w'insinga. Kubwibyo, igomba guhuzwa n'impeta inyura ifite uburoso bworoshye cyane. Umuvuduko w'uburoso uguma kuri 0.15-0.25N/cm² kugira ngo ugabanye kwangirika hagati y'insinga n'impeta inyura.
Ⅳ. Kongera urwego rwo kurinda no kunoza uburyo bwo guhuza ibidukikije
Ahantu ho gukorera imashini zikora imashini akenshi haba hari imbogamizi nyinshi, kandi ubushyuhe bwinshi, ubushyuhe buke, ubushuhe, ivumbi, imyuka yangiza n'ibindi bintu ni ibintu bisanzwe. Ibi bintu bikomeye bibangamira ibidukikije, nk' "abanzi batagaragara", bihora bibangamira imikorere n'ubuzima bw'impeta zikoreshwa mu gusimbuka ingoma. Kubwibyo, guhitamo impeta ifite urwego rukwiye rwo kurinda hakurikijwe imiterere y'aho ikorera ni nko kwambara "intwaro yo kurinda" ikomeye ku mpeta ikoreshwa mu gusimbuka.
Ku cyambu cyo hanze gifite umuyaga mwinshi wo mu nyanja n'imiraba, ni ngombwa guhitamo impeta yo kunyuramo ifite urwego rwo kurinda rwa IP67, ishobora kubuza burundu ivumbi kwinjira kandi ishobora kwinjizwa mu mazi afite ubujyakuzimu bwa metero 1 mu gihe cy'iminota 30 amazi atararenga inkombe; mu nganda zikora ibyuma bishyushye n'inganda zikora ibyuma, ubushyuhe mu iduka bushobora kugera kuri dogere 60, kandi impeta zo kunyuramo zidashobora gushyuha cyane, zifite ubushyuhe bungana na -40℃ -120℃, kandi hakoreshwa ibikoresho byo gufunga bya silikoni, bifite ubushobozi bwo kudashaza neza.
V. Isuzuma ryimbitse ry'imiterere y'imashini kugira ngo habeho imikorere ihamye
(I) Umuvuduko n'imbaraga
Iyo crane irimo gukora, umuvuduko w'impeta ihindagurika uratandukanye cyane. Umuvuduko w'impeta ihindagurika ya crane yo mu kiraro muri rusange ni 10-30r/min; umuvuduko w'impeta ihindagurika itwarwa n'uburyo bwo gukata crane yo mu munara ushobora kugera kuri 50-80r/min. Mu guhitamo impeta ihindagurika, umuvuduko wayo ugenwe ugomba kuba uri hejuru ya 20% ugereranije n'umuvuduko nyawo w'imikorere kugira ngo habeho urwego rw'umutekano. Muri icyo gihe, torque yo gutangira igomba kwitabwaho. Muri rusange, torque yo gutangira ya crane ihindagurika igomba kuba itarenze inshuro 1.5 z'impeta igenwe kugira ngo hirindwe kwangirika kw'imbere bitewe n'impeta nyinshi mu gihe cyo gutangira.
(II) Ubuzima bwa mekanike n'uburyo idashira
Igihe cy'imikorere y'impeta izunguruka gipimwa n'umubare w'izunguruka, kandi ibicuruzwa byiza bishobora kugera kuri miliyoni 50 kugeza kuri miliyoni 100. Imbere yayo ikoresha imigozi y'umupira ifite umutwaro udasanzwe wa 10-50kN; ibikoresho by'uburoso bigizwe ahanini n'icyuma cya karuboni-grafiti, kandi ubukana bwacyo bugenzurwa kuri 40-60HA Shore hardness kugira ngo harebwe ko idashira neza kandi igabanye imikorere yo kubungabunga.
(III) Ibipimo by'ihindagurika ry'ingufu n'ihungabana
Ahantu ho kubaka, kwihutisha umuvuduko uterwa n'imizingo y'iminara mu gihe cyo gukora bishobora kugera kuri metero 5 - 10 / s², naho kwihutisha umuvuduko ukagera kuri metero 50 - 100 / s². Impeta zigwa zigomba gutsinda ibizamini byo guhindagurika (inshuro 10 - 500Hz, amplitude 0.75mm) n'ibizamini byo guhungabana (half-sine wave, peak acceleration 50g, 11ms) kugira ngo habeho imikorere ihamye mu gihe cy'akazi gakomeye.
Ⅵ. Hitamo uruganda rukora impeta zo gupfunyika rufite ibirango byiza kandi rufite ubushobozi bwo gutanga serivisi nyuma yo kugurisha.
Ku isoko ry’impeta z’urukiramende, ubwiza bw’ibicuruzwa buratandukanye. Guhitamo ikirango cyizewe ni nko gushaka itara ry’urumuri mu nyanja nini. Ingiant Technology ifite izina ryiza, uburambe bwinshi n’imbaraga z’umwuga mu nganda z’urukiramende z’urukiramende za DHK038, kandi akenshi ifite amahame akomeye mu gukora no kugenzura ubuziranenge. Kuva ku kugura ibikoresho fatizo kugeza ku kugenzura inzira zo gukora, kugeza ku igenzura ry’ibicuruzwa mu ruganda, buri huza riranonosorwa kugira ngo buri pfundo ry’urukiramende rishobore kuzuza ibisabwa mu rwego rwo hejuru. Serivisi nziza yo gusezeranya nyuma yo kugurisha ni "icyizere" ingiant itanga ku bakoresha. Mu gihe cyo gukoresha pfundo ry’urukiramende, iyo habayeho ikosa, itsinda ry’inzobere nyuma yo kugurisha rishobora gusubiza vuba no gutanga ubufasha na serivisi bya tekiniki ku gihe, kimwe n’ "imvura igwa ku gihe", kugabanya igihe ibikoresho bihagarara no kugabanya igihombo cy’ubukungu giterwa n’ibura ry’ibikoresho ku kigo.
