Crane beams xav tau rau kev ua haujlwm ntawm cov khoom nqa nqa. Lawv yuav tsum muaj kev ntseeg siab thiab ruaj khov li sai tau. Reinforced qhob crane beams yog mounted rau ntawm lub taub hau ntawm txhua kab ntawm lub tsev ntau lawm, tab sis kuj yuav raug ncua los ntawm lub ru tsev trusses.

Cov pob zeb siv pob zeb siv tau siv rau hauv cov chaw ua haujlwm kub thiab tsis muaj cua sov nrog cov pob zeb ua kom muaj zog thiab qhov ntev ntawm 18 thiab 24 m rau kev teeb tsa ntawm cov khoom siv hluav taws xob siv hluav taws xob ua haujlwm hauv lub teeb thiab nruab nrab lub ntiajteb txawj nqus nrog lub peev xwm nqa txog li 32. Lawv kuj tuaj yeem siv rau ntawm cov hla hla, nyob sab nraum zoov. Cov qauv no tuaj yeem tiv taus seismic shocks mus txog qhov loj 9. Lawv yog ua los ntawm tee-section pob zeb nrog ib ncua ntawm 6 m thiab I-section rau spans ntawm 12 m. -stressed reinforcement nyob rau hauv lub longitudinal kev taw qhia yuav steel thiab muaj ib txoj kab uas hla ntawm 6 -18 mm.

Installation

Mount lawv ncaj qha los ntawm tsheb. Pab neeg installation yuav tsum yogtsawg kawg tsib tus neeg.

Ua ntej kev teeb tsa, cov khoom lag luam tau muab tso rau ntawm cov ntoo tshwj xeeb raws li qhov ntev ntawm cov kab hauv tsev siv lub jib crane. Crane beams 6 m ntev yog ntsia rau hauv txoj hauj lwm uas yuav tsum tau nrog ib tug pa traverse nrog hooks (yog hais tias cov khoom yog ntev, ces ib tug traverse nrog tongs yog siv). Thaum lub nce toj, nws yog tuav los ntawm tshwj xeeb braces kom tsis txhob tsoo lub tsev txhua. Tom qab ntawd lub beam yog leveled nyob rau hauv qhov siab thiab nyob rau hauv txoj kev npaj siv ib tug jack. Txhim kho gaskets ntawm qhov xav tau thickness, uas yog tom qab ntawd tsau nrog thauj tog rau nkoj bolts. Ua ntej, qhov fastening tau ua ib ntus, tom qab ntawd qhov kev sib tw geodetic ntawm txoj haujlwm tau ua tiav, thiab tsuas yog tom qab ntawd cov qauv thaum kawg kho.

Crane beams ua los ntawm cov hlau, ua los ntawm vuam, qhov ntev yog 6 thiab 12 m, nyob rau hauv cross section yog I-beam. Lawv yog ua los ntawm peb daim ntawv. Cov qauv zoo li no tau nruab rau ntawm cov kab ntawm cov tsev uas ua los ntawm cov hlau lossis cov pob zeb ua kom muaj zog, nrog rau cov kab ntawm cov hla hla nyob rau hauv qhov qhib huab cua. Lawv tiv taus frosts mus rau -65 ° C thiab seismic shocks mus txog 9 ntsiab lus (suav nrog).

Ntawm cov kab teeb crane no, cov khoom siv hluav taws xob siv hluav taws xob zoo ib yam nrog lub peev xwm nqa txog li 50 tons raug teeb tsa, tsim rau kev ua haujlwm nruab nrab thiab hnyav. Hlau crane beams yog ua los ntawm ob hom: zoo tib yam thiab qhov kawg, uas nyob ib sab ntawm qhov kawg ntawm cov tsev thiabkub seams. Cov hlau uas lawv tau ua yog cov qauv welded los ntawm C29 txog C44. Butt welds yuav tsum tau welded tag nrho (tsis muaj voids). Lawv yog primed thiab pleev xim rau. Cov qauv no yuav tsum tuaj txog cim. Lub cim qhia txog tus lej xaj, tus lej kos duab, kab cim cim thiab tus lej xov tooj ntau lawm. Cov khoom yuav tsum tau muab ua tiav nrog mounting gaskets nyob rau hauv ib tug npaum li cas sib npaug zos rau tus naj npawb ntawm tau txais designs. Daim ntawv thov ntawm cov ntaub ntawv technical yog yuav tsum tau.
