南昌航空大學科技學院學位論文 2噸單軌抓斗起重機設計 學生姓名：賀偉 班級：088105412 指導老師：封立耀 摘要：起重機是一種作循環(huán)、間歇運動的機械。一個工作循環(huán)包括：取物裝置從取物地把物品提起，然后水平移動到指定地點降下物品，接著進行反向運動，使取物裝置回到原位。以便進行下一次循環(huán)。通常，起重機械由起升機構（是物品能夠上下運動）、運動機構（使起重機械移動）、變幅機構和回轉機構（使物品作水平移動），加上金屬機構，動力裝置，操縱控制及必要的輔助裝置組合而成。 橋式抓斗起重機是橋架在高架軌道上運行，由起重小車帶動抓斗抓取物料的一種橋架型起重機。橋架沿鋪設在兩側高架上的軌道縱向運行，起重小車沿鋪設在橋架上的軌道橫向運行，構成矩形的工作范圍，就可以充分利用橋架下面的空間吊運物料，不受地面設備的阻礙。橋式抓斗起重機廣泛應用于電廠、煤廠等需要散料裝卸的場合，由于該設備笨重，運輸安裝困難，對其產(chǎn)品質(zhì)量檢測一般需要在現(xiàn)場進行。所以要求控制設備接線方便，體積小便于攜帶。又由于使用現(xiàn)場條件不動，還要求檢測設備有隨機手動控制功能，以保證運行時的安全。隨著對起重運輸機械控制要求的不斷提高,控制手段也越來越先進。目前國內(nèi)的橋式起重機控制系統(tǒng)都需要人在現(xiàn)場進行控制，控制方式都比較落后。在中小型起重機中, 大都采用控制器直接控制大、小車運行, 主、副鉤提升、下降重物及調(diào)速。 關鍵字：橋式抓斗起重機 運行機構 減速器 控制器 動力裝置 指導老師簽名： Design Of 2-Ton Monorail Crane Grab Sdudent: Wei He Class: 088105412 Adviser: Liyao Feng Abstract: the derrick is a kind of machine that make circulation ,intermittent sport .A work includes circulary:Take the thing device from take the thing ground to bring up the product,then the level move to specify the location to decline product carry on immediately after anti-to sport,make the thing device to return the home position ,in order to carry on next circulate.Usually , the derrick from rise the organization (make product exercised up and down),circulate the organization (make the derrick move) and become an organization and turn round the organization (make the product make the level ambulation),and the metal organization,the motive equip,the assistance that manipulate the control and necessities equips to combine. Grab bridge bridge crane is running on the elevated track, the car driven by the lifting of materials crawl grab a bridge-crane. Bridge laying on both sides along the elevated track on the vertical run, lifting trolley along the bridge in laying the track on the horizontal run, a rectangular scope of work, you can make full use of space below the bridge lifting material from Ground equipment hindered. Grab bridge cranes widely used in power plants, Mei Chang, and other needs of bulk material handling of the occasion, because of the heavy equipment, transportation difficulties installation, testing the quality of their products in general need in the field. Therefore, control equipment requirements for wiring, small size and portability. And the use of fixed-site conditions, also called a random testing equipment manual control functions to ensure the safety of operation. With the lifting of the transport requirements of the mechanical control continuously improve, more and more advanced means of control. At present the domestic bridge crane control system requires people at the scene to control, control methods are backward. In small and medium-sized crane, the most direct control over the use of controllers, car running, Lord, vice hook upgrade, dropped weights and speed.
