摘 要
6.3噸隨車起重機屬于架型起重機,它將起重和運輸相結合,不僅節(jié)省勞動力,而且極大的減小了工作強度、提高了工作效率。本次畢業(yè)設計在6.3噸隨車起重機上首次采用了伸縮臂型結構,并對起重機臂進行了優(yōu)化設計。它具有結構緊湊、易于操作的特點,可廣泛用于交通運輸、港口、倉庫、以及所有中小型工業(yè)貨物裝卸與遠距離運輸之中。
本文主要內容如下:
起升機構設計 起升機構包括液壓馬達、減速機、棘輪停止器和卷筒。減速機用來降低液壓馬達驅動速度,卷筒用于繞進或放出鋼絲繩。機構工作時,液壓馬達驅動減速機,減速機的低速軸帶動卷筒,將鋼絲繩卷上或放出,經過滑輪組系統(tǒng)使載荷實現(xiàn)上升或下降,其升降由馬達的旋轉方向而定,通過棘輪停止器實現(xiàn)制動。
起重臂設計 起重臂采用伸縮式、箱形結構。箱形結構內裝有伸縮油缸,臂的每個外節(jié)段內裝有滑塊支座,因此起重機的變幅可通過液壓缸實現(xiàn)。為了減輕吊臂自重,充分發(fā)揮鋼材的作用,吊臂的不同部位采用不同強度的鋼材。
回轉機構設計 回轉機構由回轉支承裝置和回轉驅動裝置組成。即一對脂潤滑的回轉支承裝置、蝸輪旋桿減速機和液壓馬達。這種結構自重輕、受力合理、運行平穩(wěn),可以使機構在水平面內運輸貨物。

Abstract
6.3Truck Mounted Crane (abbreviation TMC) belongs to boom-Crane .It combines the advantages .So it can greatly decrease labor intensity, increase working I use flexible boom in TMC for the first time and have a optimization design. This product has features of compact structure, easy operation. It is suitable for wide use in traffic transportantion,dock warehouse and all small-sized industries for goods loading loading and unloading and long distance transportation. Its main content includes the following aspects:
The design for winch mechanism The winch mechanism consists of hydraulic motor, reducer, ratchet wheel stop and winch drum.Reducer lowers the speed of hydraulic motor for driving the winch drum to wind or unwind the load hoisting wire rope. When working, the motor drives reducer and bring along winch drum rotation, then the wire rope is wound or unwound ,the load will be lift or lowered through pulley block system. Lifting or lowering of the load will be controlled by the rotation direction of the motor. Ratchet wheel stop is used to stop the motion of the drum, holding the load in the air.
The design of boom The boom adopts flexible type and box-shaped structure.Cylinder bodies are fitted on the boom. There are slide supports at outsides of every section of booms. The working range of TMC can outsides of every are fitted on the boom.There are slide supports at outsides of every section of booms. The working range of TMC can be realized by the extension or retraction of cylinder body. It uses different steel products in different positions for decrcasing boom’s weight and fully developing steel products’ function.
The design of swing mechanism Swing mechanism contains swing bearing and swing driver, the same is, no-oil lubricated bearings, worm-and-wheel steering gear and gydraulic motor. This structure has the advantages of light weight, reliable force on it and smooth action. It can make the load transported in the horizontal plane.
