Girder crane: imininingwane harateristiki

Kuwo wonke amazinga abantu umsebenzi girder crane ingasetshenziswa ukuhambisa imithwalo esindayo. Kuyinto indlela ephakamisa ngokufanele ku ugibelisa (inqola), okuyinto ezinwabuzelayo girder ibhuloho. Lolu hlobo imishini ingenye ezivame kakhulu. Ekuqaleni kwekhulu lama-21 ensimini ka ezweni elaliyiSoviet Union, ngokusho kombiko ahlukahlukene, ngonyaka ukukhiqiza amakhophi 1 kuya kwezingu-1.5 e 17 izitshalo ezikhethekile.

kudivayisi Jikelele

Ngokuvamile, isakhiwo crane ugongolo siqukethe imishayo span, ovame ukubizwa ngokuthi ibhuloho, nesokuphela isekela. Imishayo futhi izisekelo benziwe ngendlela nezibhebhe elingunxande. Ngaphakathi kuwo ngokulinganayo ukusabalalisa izingcindezi zizinze izindonga mpo beso kuyinto - amapuleti steel ashiselwe ngokuphambeneyo ukuba evele kwangaphakathi. Crane girder has ibhande yasenhla nemithombo yasenzansi. Izoni engenhla efakwe wesitimela ithrekhi, okuyinto sincika span imishayo. Yabeka usuthule umkhawulo ukunyakaza ovundlile. Ohlangothini ubuso imishayo zinikezwa platform encane nge handrail ngoba inkonzo crane. On the zokuthutha umphakathi ugongolo ukukhwezwa inqola. Ngesikhathi kwakhiwa ukunyakaza ihlangabezana idrayivu ekhethekile, yazalelwa ngaphansi amaqhinga ahlukahlukene.

Drive ne-ukuphakamisa crane uvumelanise

A crane ezosetshenziswa ezihambayo kuyinto drive kagesi nge cylindrical noma amasondo oyindilinga asekelayo. amasondo Cylindrical asetshenziswa esimweni lapho ezokuthutha wezimpahla Kwenziwa kuphela emgceni locondzile. eziveza tapered girder crane yayigxile komzila futhi wasebenzisa uma izindlela baye engonxantathu wesitimela izingxenye. I actuator ingase amisiwe ngokuhambisana design amaqhinga ahlukahlukene. Inqola isakhiwo Uhlaka okusekelwa egijima amasondo span imishayo. It kusungulwa Lifting indlela - kagesi noma mathupha, futhi ihlinzeka limiter usebenza hook block. Ekukhanyeni-duty crane Sibona njengoba lisetshenziswe ugibelisa kagesi, iziphi isandla nasezinsikeni uzimele bogie.

Izinhlobo ugongolo Cranes

Kuye netimphawu teluhlakasimo lweSitatimende Cranes girder kungaba asekelayo, uhlanganyela futhi gantry. Uhlobo lokuqala isakhiwo ogibele overground wesitimela ithrekhi - okuthunyelwe mpo ukwenza njenge isekela ku zazo ogibele wesitimela ngentambo. Ngokuvamile, crane ukwesekwa girder esetshenziswa endaweni evulekile for zokuhamba of imithwalo emikhulu futhi ezisindayo. Cranes Okuza asetshenziswa endlini futhi isethwe kusengaphambili ecacisiwe ekuklanyweni yokuntwela isakhiwo. inzuzo ngokuyinhloko usayizi elincane ukuphakama, futhi kungenziwa ogibele ahlukene amasayithi esitolo. ithrekhi yabo ungaba ukuma curvilinear.

Gantry imiklamo zisetshenziselwa kuphela ukuthuthwa multi-ton imithwalo. Zinikeza isakhiwo izisekelo mpo (uyakwazi ezihambelayo indiza ovundlile) kanye imishayo ovundlile. Ububanzi yabo - wezimpahla ukuphatha ukwakhiwa kwemisebenzi.

Girder Cranes nge boom

Indawo ekhethekile esakhiweni sikahulumeni esikuso crane umbhotjhongo nisebenzisa girder boom. Kuyinto design ezivamile ukulayisha futhi athula, inhlangano umsebenzi wokwakha ezizindeni ezihlukahlukene. Kowezi-crane onjalo truss elingunxantathu, ukuma unxande noma isikwele.

I boom isehlane ibhande yasenhla nemithombo yasenzansi. On phansi ubuso ipulazi Sibona uhamba nge actuator. Kwezinye izimo, lokho kungase kube abethela uvalwe ngenduku. Kulokhu, ukuhamba wezimpahla indiza ovundlile senzeka yokuhamba boom kanye umhlahlandlela uqobo.

Ugongolo ingabekwa nendawo noma i-engela ^mayelana 30-45. Crane girder nge boom has eziningi eziwusizo. Okokuqala, kuba ukunyakaza okusheshayo izimpahla ohlangothini ovundlile. Okwesibili, endaweni engaba Ukusabalala endaweni enkulu. Ekugcineni, ukungabi Bheka izindawo ezingabonakali ezibukweni - crane ungathola izimpahla, ngisho eduze ngokushesha ukusekelwa.

Izici ugongolo Cranes

Kuye ugongolo umthamo crane angabelwa ukuba ngowokuqala (kufika ku 5 m), wesibili (50 m) noma wesithathu (amathani 320) iqembu. I indophi nge drive kagesi isetshenziswa njengoba indlela ephakamisa. Uma ugongolo sinezici wesibopho crane ngempela high, yona ifakwe izindlela ephakamisa ezimbili: zamabanga aphansi naphezulu. Esinye isici esibaluleke iyona ububanzi span crane uvumelanise. Ngaphezu kwalokho - umklamo omkhulu nakakhulu ukuthi ngenxa ubukhulu okwamanje eguqa futhi ekucindezelekeni ezivukayo ngesikhathi midspan. Kukhona multi-span izakhiwo, okuyinto efakwe lapho amagceke amakhulu. Asekelwe ngqo inombolo lwemishayo - egama futhi phakathi.

girder uhlelo lokulawula crane

Crane control ngokuvamile kutsho. isilawuli Analog etholakala eduze ngokushesha opharetha, zixhunywe izintambo ukuze bephakamisa nokusingatha izindlela. Remote - Enye indlela evame lokulawula. Yekuchumana girder crane kuncike computer, okuyinto yena, kulawulwa opharetha. Cranes elawulwa kusukela gumbi asetshenziswa izindawo elikhulu lezimboni. Umshayeli, ise-cab, uphatha yonke inqubo yezokuthutha. Lokhu crane ifakwe amasignali alamu usinika Slinger, kanye nesigcawu ekhethekile obandayo.
