Isakhiwo sohlaka lwe-crane yesondo
Ubuchwepheshe obunelungelo lobunikazi buhlobene nomkhakha wemishini yobunjiniyela, ikakhulukazi uhlaka lohlaka lukakreni wamasondo.
Isingeniso Sezobuchwepheshe
Njengamanje, ukwakheka kwe-chassis ye-crane enamasondo kuvame ukwakhiwa ngama-outrigger angashintshi angaphambili nangemuva kanye nezingxenye zangaphambili nezangemuva zohlaka.Isibonelo, isakhiwo se-chassis sohlaka lwe-crane enamasondo eboniswe kuMfanekiso 1 yisakhiwo esiphuma ngaphandle esimise oku-H, okuhlanganisa ingxenye engaphambili yohlaka 1', ingxenye engemuva yohlaka 2', i-outrigger elungisiwe yangaphambili engu-3' , kanye ne-outrigger elungisiwe yangemuva.4', ukusekelwa kwe-swivel 5'nomlenze wokusekela onyakazayo ongu-6'.Umfanekiso 2 ubonisa isakhiwo se-chassis sohlaka lwe-crane yamasondo amakhulu kakhulu.Kuyisakhiwo esingaphandle esimise okuka-X, okuhlanganisa ingxenye engaphambili yozimele ongu-7', ingxenye engemuva yohlaka 8', i-fixed outrigger 9'nosekelo lwe-slewing 10' , Isigaba sangemuva esingu-8'sohlaka sihlukanisiwe. zibe izingxenye ezimbili, okuyisakhiwo esihlukene, futhi ukwesekwa kokubulala 10' kuhlelwe phakathi kwezigaba ezingemuva 8' zezingxenye ezimbili zohlaka.Ingxenye engemuva yohlaka yingxenye eyinhloko ethwala amandla ye-crane ngesikhathi sokuphakamisa umsebenzi noma ukushayela.Amandla makhulu uma kuqhathaniswa, futhi angaphansi kwesikhashana sokusikisela, ukuphakamisa umthwalo noma ukushaqeka kokushayela lapho ushayela endaweni yokusebenza eyinkimbinkimbi nezimo zomgwaqo eziyinkimbinkimbi.Ngenxa yalokho, izingxenye ezibuthakathaka zesigaba sangemuva sefreyimu zijwayele ukuqhekeka, ukuguqulwa nokungazinzi.Ngakho-ke, ukuthuthukisa ukugoba kanye nokumelana nokuhlukunyezwa kwesigaba sangemuva sohlaka kuyisihluthulelo sokuthuthukisa umthamo wokuthwala umthwalo we-crane.Ingxenye engemuva yohlaka kubuciko bangaphambili ngokuvamile ithatha isakhiwo esimise okwebhokisi esakhiwe yimishayo namapuleti.Isigaba esiphambanayo sesakhiwo esimise okwebhokisi ngokuvamile singunxande.Njengoba kuboniswe ku-Figure 3, umzuzu wokugoba we-inertia nokumelana nohlaka lwama-rectangular ngokwalo Umzuzu we-torsional we-inertia mncane, futhi kunezinkinga ezilandelayo.1) Idizayini engasindi yozimele ongunxande ifinyelele umkhawulo wayo.Ukwanda komthamo wokuthwala umthwalo womkhiqizo kuzokwandisa nakanjani isisindo sohlaka ngokwalo.Ngokukhula okuqhubekayo kwesisindo sokuphakamisa i-crane, umzuzu wokugoba kanye ne-torque yefreyimu ngesikhathi sokusebenza kokuphakamisa nakho kuyanda, futhi isakhiwo esine-cross-section enkulu siyamukelwa.Ingakwazi ukuthuthukisa ngempumelelo ukugoba nokumelana nohlaka kohlaka, kodwa ingxenye ephambanayo yomzimba ayikwazi ukunyuswa ngesisindo sokuphakamisa ngenxa yemikhawulo yokushayela.Ngesikhathi esifanayo, isisindo somzimba kufanele sihlangabezane nezimo zomgwaqo kanye nezimo zokushayela.Idizayini yokuthuthukisa yesakhiwo sozimele ongunxande isifinyelele Isimo somkhawulo asikwazi ukuhlangabezana nezidingo zomthamo womthwalo owengeziwe.2) Isakhiwo esithuthukisiwe samandla nokuqina kozimele ongunxande kuyaqedwa.Uhlaka oluwunxande lwehlisa isisindo noma alukhulisi isisindo salo...
Isakhiwo sohlaka lwe-crane yesondo
【Iphoyinti lokuvikela lobuchwepheshe】
Isakhiwo sefreyimu ye-crane enamasondo, ehlanganisa ingxenye engaphambili yohlaka, ingxenye engemuva yohlaka kanye nokwesekwa kokugwaza, okuphawulwe ngokuthi: ingxenye engemuva yohlaka isakhiwo esimise okwebhokisi le-trapezoid ehlanekezelwe, Ububanzi bengxenye engaphezulu inkulu kunobubanzi bengxenye engezansi;ingxenye engemuva yohlaka iyisakhiwo esibalulekile, usekelo lokuhlaba luwuhlobo olusekelayo olungaphezulu lokusekela lokubulala, futhi usekelo oluphezulu lokugenca luhlelwa endaweni ephakathi nendawo ephezulu yengxenye engemuva yohlaka.
【Abstract yezici zobuchwepheshe】
1. Isakhiwo sohlaka lohlaka lwe-crane yohlobo lwesondo, oluhlanganisa ingxenye engaphambili yohlaka, ingxenye engemuva yohlaka kanye nosekelo lokugwaza, oluphawulwe ngokuthi: ingxenye engemuva yohlaka iyisakhiwo esimise okwebhokisi le-trapezoidal, futhi isakhiwo esimise okwebhokisi le-trapezoidal ehlanekezelwe Ububanzi bengxenye engaphezulu yesakhiwo bukhulu kunobubanzi bengxenye engezansi;ingxenye engemuva yohlaka iyisakhiwo esibalulekile, ukusekelwa kokugwaza kuwuhlobo olusekelayo olungaphezulu lokusekela ngokubulala, futhi ukwesekwa kohlaka olungaphezulu kuhlelwa phezulu kwengxenye engemuva yohlaka Endaweni emaphakathi, ipuleti lekhava elingaphezulu isakhiwo esimise okwebhokisi sisethwe ngohlobo oluhlukaniswe izingxenye, uhlobo losekelo olungaphezulu lokusekela lokubulala luhlelwa phakathi kwezingxenye ezimbili zepuleti lekhava engenhla, futhi ukusekelwa kohlobo oluphezulu lokusekelwa kutholakala ngaphezu kohlaka lulonke , Futhi ukusekela- uhlobo lokusekela lokuhlikihla lubanzi kunozimele.2. Isakhiwo sohlaka lukakreni onamathayela eraba ngokwesimangalo 1, esibonakala ngokuthi: ingxenye ephukile yengxenye engemuva yohlaka ithatha uhlobo lwesigaba esiphambanayo esiguquguqukayo, futhi ubude bengxenye engemuva yohlaka kuncishiswe ukwenza Indawo ephambanayo yengxenye engemuva yengxenye engemuva yohlaka incane kunendawo ephambanayo yezingxenye ezingaphambili nezimaphakathi zengxenye engemuva yohlaka.3. Isakhiwo sohlaka lwe-crane yohlobo lwesondo ngokuya ngesimangalo esingu-2, lapho ingxenye engemuva yohlaka yakhiwe ngokuhlanganisa nokushiselwa kwepuleti lekhava elingaphezulu, ipuleti eliphansi eliphansi, namawebhu nhlangothi zombili ukwenza umumo we-trapezoidal ohlanekezelwe. .Isakhiwo sebhokisi.4. Isakhiwo sozimele wesondo lesondo ngokuya ngesimangalo esingu-2, lapho ingxenye engemuva yohlaka ishiselwa khona ukuze kwakheke umumo webhokisi le-trapezoid ehlanekezelwe ngepuleti lekhava engaphezulu kanye nepuleti eligobile elibunjwe ngokuhlangene u-"U".isakhiwo.
