橋式起重機總體方案及起升裝置的設計 學生姓名：祝耀欣 班級：088105441 指導老師：劉文光 摘 要：本論文課題是設計由電力驅動的50/10t橋式起重機中的機構。這些機構是起重機的主要組成部分。正是這些機構，使起重機能夠實現(xiàn)其價值，取代人力搬運貨物，既減輕勞動者的勞動強度，降低裝卸或搬運的費用，減少貨物的破損，又能提高生產(chǎn)率，在生產(chǎn)過程中進行某些特殊的工藝操作，從而提高了經(jīng)濟效益。 橋式起重機主要由金屬結構、機械部分（機構）和電氣設備三大部分組成。機械部分主要包括起升機構和運行機構等。起升機構是最重要和最基本的機構，沒有起升機構就不能稱其為起重機，其工作的好壞直接影響整臺起重機的工作性能；運行機構包括小車運行機構和大車運行機構，它是實現(xiàn)起重機將貨物橫向和縱向移動的機構。 本次設計是按照起升機構部分進行的。起升機構的設計包括起升機構布置方案的選擇、卷筒的設計、鋼絲繩的選擇，以及電動機、減速器、制動器、制動輪和聯(lián)軸器的選用和設計計算；利用AutoCAD按照確定好的各機構布置方案和設計的尺寸生成裝配平面圖，可以初步的檢查出各個零件設計是否合理，是否影響裝配。通過生成裝配平面圖，可以直觀的確定設計的正確性，從而實現(xiàn)當初的設想。 關鍵詞：橋式起重機；起升機構 指導教師簽名： I Design of Overall Program of Bridge Crane and Hosting Mechanism Student name:Zhu Yaoxin Class: 088105441 Supervisor: Liu Wenguang Abstract ：The design of some organizations in the electric drive 50/10t bridge crane is designed in this paper. These organizations are the main constituents of this crane. Because of these organizations, the hoist crane enables to realize its value, instead manpower transporting cargo, both reduces worker's labor intensity, reduces loading and unloading or the transporting expense, reduces the breakage of the cargo, and can enhance the productivity, carries on certain special craft operation in the production process, thus enhanced the economic efficiency. The bridge crane mainly consists of the metal structure, the machine part (organization) and the electrical equipment. The machine part mainly includes the lifting mechanism and the movement organization. The lifting mechanism is the most important and the most basic organization, if not these organization ,it was not able to call the hoist crane, its work quality direct influence the operating performance of the crane; The movement organization including the car movement organization and the large cart movement organization, which can realizes the cargo crosswise and the longitudinal shift. This design defers to the lifting mechanism. About designing the lifting mechanism, which includes the organization scheme of arrangement choice, the reel design, the steel wire choice, as well as electric motor, reduction gear, brake, brake pulley and shaft coupling selection with design calculation. According to determined using AutoCAD various organizations scheme of arrangement and the design size production assembly horizontal plan, may preliminary inspection each components design whether reasonably, whether affects the assembly. Through the production assembly horizontal plan, may the direct-viewing determination design accuracy, thus realized the initial tentative plan.
