Imingcele yezobuchwepheshe eyinhloko ye-tower crane

Imingcele yezobuchwepheshe eyinhloko ye Tower Cranes ihlanganisa umthamo omkhulu wokuphakamisa, umthwalo wokuphakamisa ukuphela (i-torque ephakamisayo), ubukhulu obukhulu/ubuncane be-amplitude, ukuphakama okuphezulu kokuphakama, uhlobo lwesakhiwo, indlela yokuguqula i-amplitude, ubukhulu be-tower cross-sectional, njll.

 Izici zokuphakamisa i-Tower crane

① I-boom ifakwe engxenyeni engenhla yombhoshongo, ngakho ukuphakama okusebenzayo kokuphakamisa kanye nobubanzi bokusebenza kukhulu uma kuqhathaniswa, okuyisici esivamile sezinhlobo ezihlukahlukene zama-cranes ombhoshongo.

② Ukusebenza kahle kokuphakamisa kanye nokusebenza okuzinzile.

③ Isikhathi sokusebenzisa ama-cranes e-tower cranes endaweni yokwakha ngokuvamile side. Ngemva kokuba iphrojekthi isiqediwe, idinga ukuhlakazwa, idluliswe, ihanjiswe, bese ifakwa endaweni entsha yokwakha. Inzima kakhulu kunemishini yokwakha ejwayelekile futhi inezidingo eziqinile.

④ Ama-cranes e-tower ngokuvamile aqhutshwa ngaphandle ezindaweni zokwakha. Izimo zihlukile kulezo zasendlini, futhi umshini kufanele ugcotshwe, uhlanzwe futhi unakekelwe.
5.1.2 Indlela yokufaka i-Tower crane

(1) Ukufakwa kokuzungezisa

Le ndlela isebenzisa iwintshi yokuphakamisa i-tower crane kanye ne-boom ukuyifaka ngokuzishintshanisa nokuphakamisa (uma uphakamisa umbhoshongo, i-boom isetshenziswa njengensika yokufaka).

①Sebenzisa i-crane yeloli ukuze usethe izingxenye zokufakwa ze-tower crane kuthrekhi, bese uhlanganisa umzimba wombhoshongo kanye ne-boom, futhi ukuxhume kuhlaka lokuhamba (gantry).

②Setha ihange eliphansi kanye nezinsimbi, bese uphakamisela i-boom endaweni yokufaka.

③Qinisa intambo yokuphakamisa i-boom ukuze uzungezisa umzimba wombhoshongo i-engeli ethile, bese ufake i-cantilever ephikisayo engxenyeni engenhla yomzimba wombhoshongo.

④Qhubeka uqinisa intambo yokuphakamisa i-boom ukuze umise umzimba wombhoshongo ngokuqondile uphinde uwulungise kuhlaka lokuhamba (i-gantry) (ngesikhathi sokumisa umzimba wombhoshongo, umzimba wombhoshongo udinga ukuqiniswa ngentambo).

⑤Faka i-ballast kuhlaka lokuhamba (gantry) kanye ne-counterweight.

⑥Susa i-boom bese uyiphakamisela endaweni eqondile.

⑦ Phakamisa i-boom endaweni yokusebenza bese ufaka intambo yocingo ephakamisayo.

(2) Indlela yokufaka ephephile

Sebenzisa i-crane enenjini ukuze uhlanganise ifreyimu yesisekelo (noma i-gantry), ubeke isisindo, bese ufaka umzimba wombhoshongo (okuhlanganisa uhlaka lomkhono, isigaba soguquko samakhreni abazakhela wona), ingalo yebhalansi, ingalo ephakamisayo, njll.

(3) Ukuphakama komzimba wombhoshongo wokhreni ozimelayo

Lapha sethula kuphela inqubo ye-jacking ye-crane enamathiselwe e-self-erecting tower crane. Ukuphakanyiswa kwe-crane yombhoshongo onamathiselwe ozimele wenziwa ngokuya ngezinqubo ezimbalwa eziboniswe kuMfanekiso 5-2 kusetshenziswa uhlelo lwe-hydraulic.

①Ukulungiselela ngaphambi kokugetshengwa. Nquma ubude be-jacking, phakamisa isigaba esijwayelekile ungene ku-trolley yesikebhe engu-8, susa amabhawodi axhuma umzimba wombhoshongo wangempela kanye nohlaka lomkhono, hlola futhi ulungise indawo yesilinda esisebenza ngehydraulic, i-roller, njll., xhuma ukunikezwa kwamandla we-hydraulic pump motor, bese ulungiselela ukugqekeza.

②Jack uhlaka lwemikhono kanye nesakhiwo esingaphezulu sombhoshongo. Qala ipompo likawoyela ukuze uvumele uwoyela onengcindezi ephezulu ukuthi ungene engxenyeni engenhla yesilinda esisebenza ngehydraulic. Isekhethi kawoyela engxenyeni engezansi yesilinda esisebenza nge-hydraulic ixhunywe kumjikelezo kawoyela wethangi lokubuyisela uwoyela. Umkhono kanye nesakhiwo esingaphezulu kuyaphakanyiswa futhi kuphakanyiswe kubude obudlula ingxenye eyodwa evamile (ngokuvamile u-3.3m). Umkhono ukhiywe ngephini lokubeka indawo. Ngalesi sikhathi, sonke isisindo esingaphezu komkhono sidluliselwa emzimbeni wombhoshongo ngephini lokubeka indawo.

③ Yethula isigaba esijwayelekile emzimbeni wombhoshongo. Okokuqala uhoxise i-piston rod ye-hydraulic jack ukuze wakhe indawo yesethulo, bese ushayela i-trolley yesikebhe 8 nesigaba esijwayelekile sesi-7 endaweni yesingeniso.

④ Faka umzimba wombhoshongo bese uxhuma isigaba esijwayelekile. Sebenzisa ujeke we-hydraulic ukuze uphakamise kancane isigaba esijwayelekile, uphume ku-trolley yesikebhe, bese ucindezela isigaba esijwayelekile nge-piston rod ukuze uyiwise kahle emzimbeni wombhoshongo ngezansi, futhi uwaxhume ngamabhawudi.

⑤ Khipha iphinikhodi yokumisa engu-6, wehlise umkhono wokuphakamisa 1, xhuma isigaba soguquko nesigaba esisha esijwayelekile kanye nomzimba wombhoshongo uwonke, bese ungenza umsebenzi omusha wokuphakamisa nokuphakamisa.

Uma ufuna ukuxhuma izigaba ezimbalwa ezijwayelekile ngesikhathi, phinda inqubo yokuphakamisa ukusuka ku-① ukuya ku-⑤
