The bridge crane imhando yecrane inoshandiswa munzvimbo dzemaindasitiri. Iyo crane yekumusoro ine nzira dzekumhanya dzakafanana nezambuko rinofamba rinotenderera pakakoromoka. Chikwiridzo, chikamu chinosimudza chekreni, chinofamba pazambuko. Kusiyana nemakoroni enhare kana ekuvaka, macranes epamusoro anowanzo shandiswa mukugadzira kana kugadzirisa maapplication uko kushanda zvakanaka kana kudzika pasi chinhu chakakosha. Izvi zvinotevera zvinounza mamwe maitiro akachengeteka ekushandisa epamusoro cranes.
(1) Zvose zvinodiwa
Vashandi vanofanirwa kupasa bvunzo yekudzidzira uye kutora "gantry crane driver" (code-inonzi Q4) chitupa vasati vatanga kushanda (kusimudza mashini epasi maopareta uye maopareta eremote control havafanirwe kuwana chitupa ichi uye vanozodzidziswa nechikamu ivo pachavo. ) . Mushandi anofanirwa kujairana nemagadzirirwo uye kuita kwecrane uye anofanirwa kunyatso kutevedzera mirairo yekuchengetedza. Izvo zvinorambidzwa zvachose kune varwere vane chirwere chemwoyo, varwere vane kutya kwepamusoro, varwere vane high blood pressure, uye varwere vane zvinonyadzisira kuti vashande. Vashandi vanofanira kuva nekuzorora kwakanaka uye zvipfeko zvakachena. Izvo zvinorambidzwa zvachose kupfeka slippers kana kushanda usina shangu. Zvinorambidzwa zvachose kushanda wakadhakwa kana wakaneta. Izvo zvinorambidzwa zvachose kupindura uye kufona panharembozha kana kutamba mitambo uchishanda.
(2) Mhoteredzo inoshanda
Kushanda level A5; ambient tembiricha 0-400C; hunyoro husingapfuuri 85%; haikodzeri nzvimbo dzine corrosive gas media; haikodzeri kusimudza simbi yakanyungudutswa, chepfu uye zvinhu zvinopisa.
(3) Kusimudza nzira
1. Double-beam trolley mhandopamusoro crane: Iwo makuru uye anobatsira ekusimudza masisitimu anoumbwa ne (variable frequency) mota, mabhureki, ekudzikisa magiya mabhokisi, reels, nezvimwe. Muganho switch inoiswa pamagumo edhiramu shaft kudzikamisa kusimudza nekudzika. Kana muganho uchiitwa mune imwe nzira, kusimudza kunogona kungoenda kune yakatarisana nzira yemuganhu. Frequency conversion control hoisting inoshongedzerwawo nedeceleration limit switch isati yapera, kuitira kuti ikwanise kudzikisira otomatiki kusati kwaitwa. Kune matatu magiya ekudzikisa iyo isiri-frequency control mota hoisting mechanism. Iyo yekutanga giya ndeye reverse braking, iyo inoshandiswa kune inononoka kudzika kwemitoro yakakura (pamusoro pe70% yakatarwa mutoro). Yechipiri giya i-single-phase braking, iyo inoshandiswa kudzikisa zvishoma. Inoshandiswa kune inononoka kudzika nemitoro midiki (pazasi pe50% yakayerwa mutoro), uye yechitatu giya uye pamusoro ndeyekudzika kwemagetsi uye regenerative braking.
2. Single beam hoist type: Iyo yekusimudza michina ndeye yemagetsi hoist, iyo yakakamurwa kuita inokurumidza uye inononoka magiya. Iyo ine mota (ine cone brake), bhokisi rekudzikisa, reel, tambo yekuronga mudziyo, nezvimwe. Iyo cone brake inogadziriswa neinogadzirisa nati. Tenderedza nati wachi kudzikisa kufamba kweaxial yemota. Yese 1/3 kutendeuka, iyo axial kufamba inogadziriswa zvinoenderana ne 0.5 mm. Kana iyo axial movement inopfuura 3 mm, inofanira kugadziriswa munguva.
(4) Mota inoshanda nzira
1. Double-beam trolley type: The vertical involute gear reducer inotyairwa nemagetsi emagetsi, uye yakaderera-speed shaft ye reducer yakabatanidzwa kune vhiri rekutyaira rakasungirirwa pane trolley frame in centralized drive way. Iyo mota yemagetsi inotora yakapetwa kaviri inobuda shaft, uye imwe mugumo weshaft ine bhureki. Miganhu yakaiswa kumativi ose etrolley frame. Kana muganho uchifamba munzira imwe, kusimudza kunogona kungofamba nenzira yakatarisana yemuganhu.
2. Single-beam hoist type: Iyo trolley yakabatana kune inosimudza michina kuburikidza neinotenderera inotakura. Hupamhi pakati pemavhiri maviri seti yetrolley inogona kugadziriswa nekugadzirisa pad denderedzwa. Inofanira kuve nechokwadi kuti pane gaka re 4-5 mm kune rumwe rutivi pakati pevhiri revhiri uye nechepasi reI-beam. Kumira kwerabha kunoiswa kumigumo yese yedanda, uye zvimiso zverabha zvinofanirwa kuisirwa kumagumo evhiri.
