前移式手動(dòng)液壓裝卸叉車設(shè)計(jì)

摘要

前移式手動(dòng)液壓叉車是一種無(wú)污染，無(wú)動(dòng)力的裝卸產(chǎn)品，該產(chǎn)品具有結(jié)構(gòu)緊湊，運(yùn)輸靈活，操作簡(jiǎn)單，回轉(zhuǎn)半徑小等特點(diǎn)。適用于工廠，車間，倉(cāng)庫(kù)，車站，碼頭等處的貨物搬運(yùn)與堆垛。對(duì)于那些有防火，防爆要求的場(chǎng)地（如印刷車間，油庫(kù)，碼頭，倉(cāng)庫(kù)等）更為適用。若配合托盤裝箱，集裝箱等及可實(shí)現(xiàn)單元化運(yùn)輸，有效減少了零部件的碰撞，劃傷和堆放面積，減少搬運(yùn)工作量，提高搬運(yùn)效率。本說(shuō)明書(shū)是在對(duì)市場(chǎng)調(diào)查的情況下，發(fā)現(xiàn)手動(dòng)液壓叉車比較常見(jiàn)，前移式叉車也比較常見(jiàn)，唯獨(dú)缺少的就是前移式手動(dòng)液壓叉車，前移式手動(dòng)液壓叉車是集各種叉車的優(yōu)點(diǎn)于一身，但造價(jià)偏貴，市場(chǎng)上庫(kù)存不多。本設(shè)計(jì)主要內(nèi)容包括了對(duì)底盤、垂直升降裝置、前移裝置貨叉、門架以及液壓系統(tǒng)的設(shè)計(jì)。由剪刀工作原理聯(lián)想到剪式叉架的前移，由梯形螺紋絲杠的自鎖性，設(shè)計(jì)出只有手搖能控制貨叉前進(jìn)后退，松手并不移動(dòng)的前移方式。通過(guò)提出方案并加以論證，選出最優(yōu)設(shè)計(jì)方案的原則，闡述了前移式手動(dòng)液壓叉車的結(jié)構(gòu)設(shè)計(jì)和工作原理，論證了它的適用性，可行性。

ABSTRACT
Forward type manual hydraulic forklift is a pollution-free, no power handling products, the product has the advantages of compact structure, flexible transportation, simple operation, small turning radius etc.. Apply to factory, workshop, warehouse, station, dock and cargo handling and stacking. For those with fire, explosion-proof requirements of the site ( such as printing workshop, oil depots, docks, warehouses and other ) is more applicable. If match tray packing, container and can realize the transport units, effectively reduce the parts of the collision, scratch and stacking area, reduce the workload of material handling, improve handling efficiency. This statement is on the market investigation, found the manual hydraulic forklift are relatively common, type forklift is also common, but is the lack of forward type manual hydraulic forklift, reach manual hydraulic forklift is a forklift various merit in a body, but the cost is expensive, the market inventory is not much. The design of the main contents include the chassis, the vertical lifting device, advancement device fork, door frame and the design of hydraulic system. Composed of scissors principle to associate scissor fork movement, by trapezoidal screw self-locking, designed only hand can control the fork back and forward, let go does not move forward mode. The proposed scheme tries to prove, the optimal design principle, elaborated reach type manual hydraulic forklift structure design and work principle, demonstrates its applicability, feasibility.
