Ibhuloho laseZhongtang elisemgwaqweni onguthelawayeka u-xx linesikhathi esiyinhloko esingu-32.5 + 4 × 45 + 32.5m kanye nesigaba esilinganayo ibhida lebhokisi likakhonkolo eliqinisiwe eliqinile (indlela yangemuva kwe-tension), enobude obuphelele obungu-245.9m. Ibhande lebhokisi liyigumbi elilodwa, ukuphakama kwe-beam phakathi nendawo kungu-308.25cm, ububanzi bophahla bungu-1100cm (ububanzi bedekhi yebhuloho bungu-12m), kanti ububanzi bepuleti eliphansi ngu-480cm. Iwebhu ithambekele, futhi ibanga eliphakathi nendawo phezulu lingama-570cm. Iziphetho zemishayo futhi phakathi kwayo yonke imishayo kuhlinzekwa ngemishayo, kanti okunye kuhlinzekwa ngama-diaphragms njalo nge-15m.
Isisekelo se-pier sebhuloho elikhulu yizinqwaba ezi-4 eziboshiwe eziphonswe endaweni enobubanzi obungu-120cm, ezishumekwe edwaleni elingaphezu kuka-50cm. Umzimba we-pier wamukela isakhiwo esinamakholomu amabili kakhonkolo oqinisiwe nobubanzi obungu-180cm.
Lapho ibhuloho lakhiwe, kusetshenziswa indlela ye-SSY, okungukuthi, indlela yokuphusha enamaphuzu amaningi isetshenziselwa ukumisa ugongolo. Izici zale ndlela yilezi: amandla okusabela avundlile lapho usunduza (udonsa) umzimba wogodo uyahlakazwa futhi usebenze endaweni ngayinye, futhi ukusebenza kokusunduza (ukudonsa) kungalawulwa phakathi nendawo. Njengoba zingekho izinsimbi zesikhashana phakathi nomsebenzi, ingxenye engaphambili yebhande lebhokisi ixhunywe ku-truss yensimbi eyakhiwe ngobude obungu-30m njengenduku yomhlahlandlela.
Uma ibhande lebhokisi elakhiwe ngaphambilini liphushelwa phezulu, lenziwa ngomjikelezo ngokwezinqubo zokuqhubekela phambili→uhlaka lokuphakamisa→uhlaka lokuwisa→ukuqhuma. Umfanekiso 1 ubonisa isimo somjikelezo.
Umdwebo wenqubo ye-push-up
1——Isilinda Esiqondile;2——Hudula Ikhanda;3——Slideway;4——PuRod;5——HIsilinda sasempumalanga
Kungabonakala ukuthi ukuze uqaphele lo mjikelezo wohlelo, isilinda esivundlile siqedela isenzo sokuphusha ibhande lebhokisi ngomshini wokuslayida, futhi isilinda esime mpo siqedela isenzo sokuphakamisa nokuwisa ugongolo. Okusho ukuthi, isilinda esivundlile kanye nesilinda esime mpo kwenziwa ngokushintshana.
1. Uhlelo lwe-Hydraulic lwe-multi-point pusher beam nokulawula kwalo
Kokubili isilinda esivundlile kanye nesilinda esime mpo zishayelwa ngamanzi futhi zilawulwa ugesi. Ubude obuphelele bebhande lebhokisi elizodudulwa ibhuloho lingama-225m, futhi imitha yomugqa ngamunye inesisindo esingu-16.8t, nesisindo esiphelele esingaba ngu-3770t. Ngakho-ke, ingqikithi yamasilinda avundlile ayi-10 namasilinda aqondile angama-24 (ingcindezi kawoyela ingu-320kg/cm2 kanye nokuphumayo okungama-250t) ahlelwa. Kunezinsika ezi-5 ezinamasilinda avundlile, ezi-2 zomgodi ngamunye; kukhona 6 pier for amasilinda mpo, 4 pier ngamunye.
Ujeke omile uqedela ukuphakamisa nokwehliswa kwe-beam. Enqubweni yokwakha, ibhuloho lonke alidingeki ukuba livumelaniswe, futhi izinsimbi ziyadingeka ukuba zihlukaniswe, ngakho-ke ayikho inkinga yokulawula okuphakathi. Ukulawula kwayo ngogesi kungaqedela ukuphakamisa noma ukwehlisa ujeke okuqhubekayo, futhi kungagcwalisa nefomu lokugijima.
Ujeke ovundlile uqedela isenzo sokuphusha ugongolo. Inqubo yokwakha idinga ukuthi lonke ibhuloho livumelane, okungukuthi, ukukhipha noma ukumisa ngesikhathi esifanayo, ngakho ukulawulwa okumaphakathi kwejekhi evundlile kuyasethwa, futhi ibhokisi likagesi lokulawula eliphakathi nendawo limiselwe le njongo.
Ukusetshenziswa kojekhi abavundlile kanye namajekhi aqondile kuyanda kancane kancane, futhi ibhande lebhokisi lenziwe ngaphambili libe ngu-15m umjikelezo ngamunye. Ngokukhula okuqhubekayo kwebhokisi lebhokisi, inani lama-jacks asetshenziswa kancane kancane liyakhula. Emijikelezweni embalwa yokugcina yokwenziwa, wonke amasethi ayi-10 ojeke abavundlile kanye namajekhi aqondile angama-24 asetshenziswa.
Ukuze kuxhunywe indawo ngayinye negumbi lokulawula eliphakathi nendawo, sifake isistimu yokudlulisa umsindo ye-intercom. Ukuzijwayeza kufakazele ukuthi uhlelo lokudluliswa kwe-hydraulic nezindlela zokulawula ezibalwe ngenhla zinokwethenjelwa ukusetshenziswa.
Ake sikhulume ngokuhlangenwe nakho okuthile kwezinkinga ezimbalwa zokudluliselwa kwe-hydraulic ye-push frame beam indlela yokubhekisela.
1. Inkinga yokulawulwa kwengcindezi esezingeni le-hydraulic system. Inkinga yokulawulwa kwengcindezi yesinyathelo ngesinyathelo ibekwa phambili ngenxa yokucatshangelwa okuhlukile kokumelana nokungqubuzana okuqinile kanye nokumelana nokuqina kwe-dynamic lapho ibhande lebhokisi lihamba. Esikhathini esedlule, kwakuhlale kukholakala ukuthi uhlelo lwe-hydraulic kufanele lube nezingcindezi zamafutha ezimbili noma ezintathu: lapho ukumelana nokuqina kwe-static kunqotshwa, kusetshenziswa ingcindezi enkulu yamafutha; futhi umfutho kawoyela omncane usetshenziswa lapho ugongolo lwebhokisi lushelela. Indlela yokushintsha i-hydraulic system ngokuxhuma ama-valve okusiza ahlukene asethiwe. Ngale ndlela, i-hydraulic system kanye nokulawula kwayo kuyinkimbinkimbi kakhulu. Umkhuba wethu ufakazele ukuthi ukucindezelwa kwamafutha kwesistimu ye-hydraulic akuxhomeki kuwo ngokwawo, kodwa ekuphikisweni kwangaphandle kwe-jack. Okusho ukuthi, lapho uhlelo lwe-hydraulic lusebenza, ukucindezela kukawoyela akunqunywa inani elibhalwe igama lepompo likawoyela, kodwa ngokumelana okuphelele okuhlangatshezwane nakho ngesikhathi sokugeleza kwamafutha ebuyela ethangini likawoyela ngemuva kokushiya iphampu. . Uma i-jack ingenakho ukumelana (umthwalo), ingcindezi yepompo yamafutha inqunywa kuphela ukumelana kwepayipi; uma amafutha avela ku-oil pump ngokushesha angena emkhathini noma ku-tank yamafutha, ukucindezela kwepompo yamafutha kuyoba zero; uma ukumelana (umthwalo) R we-jack kwanda, ukucindezela kwepompo yamafutha nakho kwanda. Lapho i-jack ilayishwa, ukucindezela kwepompo yamafutha kunqunywa i-valve yendlela eyodwa; lapho i-jack ilayishiwe, ukucindezela kwepompo yamafutha, okungukuthi, ukucindezela kwamafutha kwesistimu, kuzonqunywa ukumelana kwe-jack. Ukucindezela kwamafutha emsebenzini kunqunywa umthwalo wejack. Okusho ukuthi, ukucindezela kwamafutha esistimu ye-hydraulic kuzozishintsha ngokwawo ngokumelana kwangaphandle, ngakho-ke ukulawulwa kwesinyathelo ngesinyathelo akudingekile.
2. Vumelanisa udaba lwama-jack avundlile. Inqubo yokuphusha idinga ukuthi ojeke abavundlile kwesokunxele nakwesokudla kufanele baphushele ugongolo phambili ngesivinini esifanayo, ngaphandle kwalokho ugongolo luzochezukiswa lapho lushibilika. Yiqiniso, into yokuqala abantu abayicabangelayo ukuthi amandla asetshenziswa ama-jack avundlile kwesokunxele nakwesokudla emzimbeni we-beam kufanele alingane, okulungile. Lapho i-symmetry yesokunxele nesokudla ye-boam body inhle kakhulu, futhi ukumelana kufinyelela kwesokunxele nakwesokudla, yiqiniso, amandla asetshenziswa ama-jacks avundlile kwesokunxele nakwesokudla kufanele futhi alingane. Okwesibili okucatshangwayo ukuthi isivinini sokuya kwesokunxele nesokudla kufanele futhi silingane. Ngale ndlela, i-beam ingahamba kahle futhi iqonde. Kodwa-ke, kunzima ngomzimba we-beam ukuqinisekisa ukuthi isigaba ngasinye kufanele silingane kwesokunxele nakwesokudla, futhi ukumelana kwesokunxele nakwesokudla kufanele kulingane. Ukucindezela kwamafutha okuhlobene nesistimu okukhulunywe ngayo ngenhla kunqunywa ukumelana kwangaphandle. Kungacatshangwa ukuthi ama-jacks angakwesokunxele nangakwesokudla kumele asebenze ngaphansi kwezimo ezihlukene zokucindezela kwamafutha, ngakho-ke ingabe ijubane lamajack kwesokunxele nakwesokudla lizovumelaniswa ngalesi sikhathi? Ukuze uthole umzekeliso, kucatshangwa ukuthi yipheya elilodwa kuphela likajeke elisebenzayo. Njengoba sisetha iphampu eyodwa ngejekhi eyodwa, lokhu kuxazulula inkinga yokuvumelanisa isivinini kahle kakhulu. Ngenxa yokuthi iphampu kawoyela esiyisebenzisayo iyiphampu yokufuduka elungile, ngokombono, kungakhathaliseki ukuthi ukumelana nokukhiqizwa kukawoyela kuhlangana nepompo kawoyela (okungukuthi, kungakhathaliseki ukuthi umfutho kawoyela wohlelo uphezulu kangakanani), izinga lokugeleza kwawo liphakeme. engaguquki. Ngakho-ke, ama-jacks angakwesokunxele nangakwesokudla kufanele avumelaniswe. Kunjalo, lesi siphetho singaphinde siqondiswe esimweni sezinkambo ezimbili ezineziqongo ezine, izinsika ezintathu ezineziqongo eziyisithupha, izinsika ezine ezineziqongo eziyisishiyagalombili, noma izinsika ezinhlanu ezineziqongo eziyishumi. Ngakho-ke, indlela yethu yepompo eyodwa kanye nephezulu ingabona kangcono inkinga yokuvumelanisa kwesokunxele nakwesokudla. Ukuzijwayeza kuphinde kwafakazela ukuthi ku-push beam, umugqa omaphakathi womugqa webhokisi awushintshiwe (uma sikhuluma ngokuqinile, kufanele ususwe kancane ukusuka kwesokunxele kuye kwesokudla kodwa ungahlala ugcinwe ebangeni elithile). Inqubo yokwakha idinga ukuqapha ngokucophelela ukuchezuka komugqa ophakathi nendawo. Uma idlula u-2cm, idinga ukulungiswa (ngesiqondiso esiseceleni). Phakathi nenqubo ye-push-up, inani lokulungiswa lincane kakhulu. Isikhathi esisodwa noma ezimbili kuphela ekusunduzeni okungamashumi amathathu (ibhande lebhokisi elingu-15m). Lokhu kungabhekwa njengomphumela ohlangene wezinto eziningi ezihlosiwe, ngoba mayelana nemishini ye-hydraulic, iphampu kawoyela inephutha lokugeleza, i-jack inezinkinga zangaphakathi zokuvuza (i-jack ngayinye ihlukile, futhi i-piston ingase ibe nezikhundla ezahlukene. ), kanye nesistimu Ukuvuza kwamanye amadivaysi ngaphakathi, njll., okungangqubuzani nesiphetho sethu esingenhla.
3. Vumelanisa udaba lojeke abame mpo. Ama-jack ethu aqondile asebenza ngepompo enamajekhi amane, futhi i-valve yokuvumelanisa kufanele imiswe, ngoba i-valve yokuvumelanisa (noma i-diverter valve) ingenza ama-jacks amaningana ngaphansi kwemithwalo ehlukene (ukumelana) isathola isilinganiso esinqunyiwe noma ukunikezwa kukawoyela okulinganayo ukuze kuzuzwe. ukuvumelanisa. Kodwa uma ucabangela ukuthi i-valve yokuvumelanisa inezindawo ezimbili kuphela. Ukuze kwenziwe lula ukwakheka kohlelo, akukho valvu yokuvumelanisa efakiwe. Uma kucatshangelwa ukuthi izisindo zesokunxele nezilungile zebhande lebhokisi zinokulinganisa, akuyona inkinga enkulu ukwenza kanjalo. Ukuzijwayeza kufakazele ukuthi isilinganiso silungile, ujeke ome mpo ngokuyisisekelo uyakhuphuka futhi awe ngokuhambisanayo, futhi ayikho inkinga ekuphakamiseni nasekuweni kwenduku.
