GBT 15-88 hombe semicircular musoro ine tenon bolt tower crane bolt loose ndoita sei kugadzirisa dambudziko rebhaudhi rakasununguka.

GBT 15-88 hombe yakatenderera musoro ine mortise bolt
Countersunk head screws anoshandiswa kubatanidza zvinhu zviviri kana kupfuura uye akakosha muhupenyu hwezuva nezuva kana kugadzirwa kwemaindasitiri.
Fastener ine musoro nescrew (cylinder ine shinda dzekunze), inoshandiswa nenzungu pakusunga zvidimbu zviviri zvine maburi.
Mhando yekubatanidza iyi inonzi bolt connection. Kana iyo nati isina kuvharwa kubva kubhaudhi, zvikamu zviviri izvi zvinogona kupatsanurwa, saka iyo dowel bhaudhi yekubatanidza ndeye inodzikwa.
Tower crane bolt sunungura maitiro ekugadzirisa dambudziko re bolt loose
Chii chinokonzera kusunungura tower crane bolt? Nzira yekuita sei nekusunungurwa kweshongwe crane bolts? Imwe mukana ndeyekuti nekuda kwekufamba kwemuchina, bhaudhi haina kusununguka zvakakwana kuti iite kusunungura; Panewo mukana wekusava nehanya kwevanhu uye kutadza kuomesa mabhaudhi. Uye iyo bolt anti loose kazhinji haina kunaka neiyo bhaudhi yekugadzira kurongeka haina kukwirira, anti loose dhizaini kukanganisa kunokonzerwa; Zvichida bhaudhi rinoiswa uye rinoparadzaniswa kakawanda, uye zino reshinda rinotsvedza.
Inowanzo shandiswa tm 60, 80 tm's tower crane slewing bearing under the above is slewing bearing, jib, balance arm, tower caps, cab, etc., huremu hwayo pa20 ~ 30 t, in the working state of tower crane, uye yakatwasuka. simba rinogadzirwa nemutoro une simba uye nguva yekukotama, torque, saka iyo vice ye bhoti yekubatanidza zvinodiwa inofanirwa kunyatso kuenderana nezvinopihwa, iyo nguva yekusimba, isina kuomesesa kana kusununguka zvakanyanya, yakanyanya kusimba, Iyo bhaudhi ichashanda kwenguva yakareba. nguva panguva kana pedyo nekupa simba, kuitira kuti bhaudhi ichakurumidza kuneta uye kuputika, zvichikonzera kuputsika; Kunyanya kuregedzera, mabhaudhi uye zvidimbu zvekubatanidza zvehama kufamba, bhaudhi musoro pasi pekudzokororwa kukanganisa uye kukuvara, zvichikonzera tsaona dzakakomba dzeshongwe.
Mubasa reshongwe crane, inowanzoiswa pasi pekuzununguka, kukanganisa uye kuchinjika mutoro, uye kune zvakare mwaka ine huru tembiricha shanduko. Neiyi nzira, simba rekukwenya pakati pe screw inclined surfaces mu bolt connection rinogona kupera kana kudzikira ipapo. Kuitika kwakadzokororwa kwechiitiko ichi kuchaita kuti kuwirirana kusununguke zvishoma nezvishoma, kunokanganisa kusimba uye kuoma kwekubatanidza Izvi zvinogona kuitika mune chero chikamu chechimiro chemuviri weshongwe, uye bhaudhi rinosunungurwa muzvikamu zviri pamusoro rinoonekwa sechinhu chevanhu. Kuzvikwirira shongwe crane lift tower, pamberi peshongwe yega yega crane jack-up, ese ekubatanidza mabhaudhi kuti asunungure mana kana masere, kumusoro kumagumo, suma shongwe dzakajairika, chikamu chakajairwa chinosuma chikamu chakajairwa, pasi pekutenderera kwepamusoro nepasi. mabheya pakati pebhaudhi, uye chikamu chezasi chekusimbisa bhaudhi yekubatanidza hachiwanzo kuregeredza, yakasimbisa iyo pakarepo, uye pasi pekutenderera kweyepamusoro bhengi pakati pebhaudhi Mukushanda kwekusimbisa, kazhinji haina kusimbiswa nekukurumidza nekuti kune inopfuura imwe jacking. chikamu plus standard chikamu uye jacking inoenderera. Nenzira iyi, zvinogoneka kuti mabhaudhi ekubatanidza emutsetse uyu haana kusimbiswa mushure mekunge jacking yapera. Muenzaniso unowanikwa mukuongorora ndiyo muenzaniso.
Bolt yekubatanidza zvinodiwa kune tower crane standard chikamu:
* * *, tower crane work, seti yekubatanidza kana iyo imwechete yejoint pre-tightening simba yakakura kwazvo, mutevedzeri we axial force ye bolt yekubatanidza inogona kusiyanisa zvakanyanya, hombe bhaudhi pretightening pasi pemutoro unorema kwenguva yakareba, nyore kugadzira. kuneta kutyoka, kwakawanikwawo muongororo chaiyo sere hwaro hwebhaudhi yekutyoka, ndeyechiitiko ichi. Kuchenjerera kunofanirwa kubhadharwa kune kuenderana kweiyo pre-kusimbisa torque mukuisa. Mukushanda kwemunda, nekuda kwesimba rakasiyana revashandi, pre-tightening torques yechina column bolts ingangove yakasiyana, saka kushandiswa kwema torque wrenches kunogona kudzorwa zviri nani. Kutaura zvishoma, inofanirwawo kuongororwa uye kugadziridzwa nevanoziva shift masters.
Chechipiri, mamiriro ekusungirira ezvese mabhaudhi ekubatanidza anofanirwa kutariswa kamwechete mushure mekugadzwa kwekutanga kweiyo shongwe crane kwave kushanda kwemashift maviri. Muhafu inotevera mwedzi kana zvakadaro, mabhoti muzvikamu zviri pamusoro anofanira kuongororwa kunyanya mushure mokunge shongwe yasimudzwa. Nzvimbo yeruoko rweshongwe inofanirawo kutenderedzwa kana uchitarisa. Mabhoti anofanirwa kutariswa akananga pasi pechinzvimbo chesimba ruoko, kuitira kuti ive yakavimbika uye inobudirira kutarisa kana mabhoti akasimbiswa.
Chechitatu, kana shongwe crane yatamiswa, ese shongwe muviri inobatanidza mabhaudhi inofanirwa kuongororwa zvakadzama, derusting uye lubrication. Kutsemuka, kupfeka, ngura yakakomba, deformation yepurasitiki yakazara kana yemunharaunda uye zvimwe zvisizvo zvinofanirwa kutsiviwa. Inokurudzirwa kuishandisa kwete kanopfuura kaviri kudzivirira kuneta kukanganisa. Ichi chinodiwa, iyo iripo tower crane inogona kusasangana neruzhinji. Kana zvikaonekwa kuti pane kushayikwa, haifaniri kugadziriswa uye kugadzirwa pachayo. Nokuti chikwata chekuvaka hachisi nyore kudzora hutano hwekugadzirisa uye zvinhu zvebhoti yakakwana, zvinofanira kunge zviri nani kuitenga kubva kune yekutanga tower crane production factory. Iyo bhaudhi yakakwana inofanirwa kucherechedzwa nemugadziri uye giredhi.
Tower crane kuchengetedza yekutarisa uye anti-collision system inoshandiswa kune akawanda-tower crane operation kuchengetedza anti-collision alarm system munzvimbo yakaoma yekuvaka, inogona kudzivirira shongwe crane kubonderana, kudzivirira uye kuderedza kudhumhana mukushanda kwekubatana kweboka remichina, vandudza kuchengetedzwa kwekuvaka kwenzvimbo! Iyo sisitimu iri nyore kuisa uye kushanda, uye inogona kuridza nekudzivirira akawanda tower cranes munzvimbo yakati yesaiti. Panguva imwecheteyo, iyo anti-collision system ye tower crane yakachengeteka uye inoshanda ine simba yekutarisa sisitimu, iyo inogona kubatsira shongwe crane vanoshanda kudzivirira njodzi dzakakomba uye dzinouraya dzinokonzerwa nekukanganisa kushanda.
