GBT 15-88 mutu waukulu wozungulira wokhala ndi bawuti yakufa
Zomangira zamutu za Countersunk zimagwiritsidwa ntchito kulumikiza zinthu ziwiri kapena zingapo ndipo ndizofunikira kwambiri pamoyo watsiku ndi tsiku kapena kupanga mafakitale.
Chomangira chokhala ndi mutu ndi wononga (silinda yokhala ndi ulusi wakunja), yogwiritsidwa ntchito ndi nati pomangira magawo awiri ndi mabowo.
Kulumikizana kwamtunduwu kumatchedwa kulumikizana kwa bawuti. Ngati natiyo ili yosasunthika kuchokera ku bawuti, magawo awiriwa amatha kupatukana, kotero kulumikizana kwa dowel ndi kulumikizana komwe kumatha.
Tower crane bolt imamasula momwe mungathanirane ndi vuto la bawuti lotayirira
Kodi choyambitsa kumasulidwa kwa bawuti ya tower crane ndi chiyani? Kodi mungathane bwanji ndi kumasulidwa kwa mabawuti a tower crane? Chotheka chimodzi ndi chakuti chifukwa cha kayendedwe ka makina, bawutiyo simamasuka mokwanira kuti isungunuke; Palinso kuthekera kwa kunyalanyaza kwaumunthu ndi kulephera kumangitsa mabawuti. Ndipo bawuti anti loose nthawi zambiri si yabwino ndi kulondola kwa bawuti sikukwera, zosokoneza zolimbana ndi kapangidwe kake; Mwina bawutiyo imayikidwa ndikuphwanyidwa nthawi zambiri, ndipo dzino la ulusi limatsika.
Nthawi zambiri amagwiritsidwa ntchito tm 60, 80 tm's tower crane slewing under the above is slewing bear, jib, balance arm, tower caps, cab, etc., kulemera kwake pa 20 ~ 30 t, pogwira ntchito ya tower crane, ndi yoyima. mphamvu yopangidwa ndi katundu wosunthika ndi mphindi yopindika, torque, kotero kuti zofunikira zolumikizira bawuti ziyenera kukhala molingana ndi zomwe zimaperekedwa, mphindi yolimba, osati yolimba kwambiri kapena yotayirira, yolimba kwambiri, bawutiyo idzagwira ntchito kwa nthawi yayitali. nthawi kapena kuyandikira kutulutsa mphamvu, kotero kuti bawuti posachedwa kutopa ndi kusweka, zomwe zimabweretsa kusweka; Zotayirira kwambiri, mabawuti ndi zolumikizira zolumikizana, bolt mutu pansi pa kukhudzidwa mobwerezabwereza ndi kuwonongeka, zomwe zimapangitsa ngozi zazikulu za nsanja.
Pogwira ntchito ya tower crane, nthawi zambiri imakhala ndi kugwedezeka, kukhudzidwa ndi katundu wosiyanasiyana, komanso pamakhala nyengo zokhala ndi kusintha kwakukulu kwa kutentha. Mwanjira imeneyi, mphamvu yolimbana pakati pa malo okhotakhota pamaboti imatha kutha kapena kuchepa nthawi yomweyo. Kuchitika mobwerezabwereza kwa chodabwitsa ichi kudzapangitsa kugwirizanako pang'onopang'ono kumasuka, kukhudza kukhwima ndi kulimba kwa kugwirizana Izi zikhoza kuchitika mu gawo lililonse la thupi la nsanja, ndipo kumasulidwa kwa bawuti m'zigawo zapamwambazi kumaonedwa kuti ndi chinthu chaumunthu. Self-climbing tower crane lift tower, pamaso pa nsanja iliyonse ya crane jack-mmwamba, mabawuti onse olumikizira kuti amasule anayi kapena asanu ndi atatu, kumapeto kwapamwamba, yambitsani nsanjazo ndizokhazikika, gawo lokhazikika lidzayambitsa gawo lokhazikika, pansi pa kuzungulira kwapamwamba ndi kumunsi. mayendedwe pakati pa bawuti, ndi m'munsi gawo la kumangitsa bawuti kugwirizana si kawirikawiri kunyalanyazidwa, kukhwimitsa nthawi yomweyo, ndipo pansi kasinthasintha wa kumtunda kunyamula pakati pa bawuti Mu ntchito yolimbitsa, nthawi zambiri osati omangika nthawi yomweyo chifukwa pali jacking oposa mmodzi. gawo kuphatikiza gawo muyezo ndi jacking akupitiriza. Mwanjira iyi, ndizotheka kuti ma bolts olumikizira a wosanjikiza awa salimbitsidwa pambuyo poti jacking ikamalizidwa. Chitsanzo chopezeka pakuwunika ndi chitsanzo.
Zofunikira polumikizira bolt pagawo lokhazikika la Tower crane:
* * *, ntchito ya nsanja ya crane, kugwirizana pamene mphamvu yolumikizirana isanakwane ndi yayikulu kwambiri, wachiwiri kwa axial mphamvu yolumikizira bawuti imatha kusiyanasiyana, kuwongolera kokulirapo pansi pa katundu wolemetsa kwa nthawi yayitali, kosavuta kupanga. kutopa fracture, anapezekanso kwenikweni mayeso asanu ndi atatu bawuti maziko a fracture, ndi chodabwitsa ichi. Chisamaliro chiyenera kulipidwa ku kusasinthika kwa ma torque omwe amawunikiridwa kale pakuyika. Pogwira ntchito m'munda, chifukwa cha mphamvu zosiyana za ogwira ntchito, ma torque omwe amawongoleredwa kale azitsulo zinayi zazitsulo amatha kukhala osiyana, kotero kuti kugwiritsa ntchito ma wrenches amatha kuyendetsedwa bwino. Kunena zocheperako, iyeneranso kuyang'aniridwa ndikusinthidwa ndi akatswiri odziwa kusintha.
Chachiwiri, kukhazikika kwa mabawuti onse olumikizira kuyenera kuyang'aniridwa kamodzi mutangokhazikitsa koyambirira kwa crane ya nsanja yakhala ikugwira ntchito kwa masinthidwe awiri. Mu theka lotsatira la mwezi kapena apo, ma bolts omwe ali pamwambawa ayenera kuyang'aniridwa makamaka nsanjayo ikadzakwezedwa. Malo a mkono wa nsanja ayeneranso kuzunguliridwa poyang'ana. Maboti oti afufuzidwe ali pansi pa malo a mkono wokhazikika, kuti akhale odalirika komanso ogwira mtima kuti awone ngati ma bolts ali olimba.
Chachitatu, crane ya nsanja ikasamutsidwa, ma bolt onse olumikizira nsanja amayenera kuwunikiridwa mwatsatanetsatane, kuwononga ndi kuthira mafuta. Ming'alu, kuvulazidwa, dzimbiri lalikulu, kupindika kwa pulasitiki wamba kapena m'deralo ndi zina zolakwika ziyenera kusinthidwa. Ndibwino kuti mugwiritse ntchito kwa zosaposa kawiri kuti mupewe kuwonongeka kwa kutopa. Chofunikira ichi, crane ya nsanja yomwe ilipo mwina siyingakwaniritse ambiri. Zikapezeka kuti pali kusowa, siziyenera kukonzedwa ndikuzipanga zokha. Chifukwa gawo lomanga silikhala losavuta kuwongolera kuwongolera ndi zinthu za bawuti yabwino kwambiri, ziyenera kukhala zabwino kugula kuchokera ku fakitale yoyambira yopanga crane. Bolt yabwino iyenera kuzindikirika ndi wopanga ndi kalasi.
Tower crane kuwunika chitetezo ndi odana ndi kugunda dongosolo ntchito Mipikisano nsanja crane ntchito chitetezo odana ndi kugunda alamu m'malo zovuta zomangamanga, angathe kuteteza nsanja crane kugunda, kuteteza ndi kuchepetsa kugunda mu ntchito yogwirizana ya gulu la makina, sinthani chitetezo chomanga pamalopo! Dongosololi ndi losavuta kukhazikitsa ndikugwiritsa ntchito, ndipo limatha kuwopseza ndi kuteteza ma cranes angapo a nsanja pamalo enaake. Nthawi yomweyo, anti-collision system ya tower crane ndi njira yowunikira yotetezeka komanso yothandiza, yomwe ingathandize oyendetsa nsanja kuti apewe ngozi zazikulu komanso zakupha zomwe zimachitika chifukwa cha zolakwika za opareshoni.
