Internal structure of the lifting device the lifting device is mainly composed of a gear mechanism, the bracket, the worm, the guide body, the arm, the upper and lower casing components.Gear mechanism gear mechanism including large and small gear, wrapped around a pulley, the central axis and the stopper buckle, safety device consisting of a torsion spring.

 
選用閉式齒輪傳動(dòng)，大、小齒輪均選用鋼，經(jīng)調(diào)質(zhì)處理，屬于軟齒面，由于閉式軟齒面齒輪傳動(dòng)常見(jiàn)的失效形式為齒面點(diǎn)蝕，故設(shè)計(jì)時(shí)按齒面接觸疲勞強(qiáng)度計(jì)算，按齒根彎曲疲勞強(qiáng)度進(jìn)行校核。支架支架用于固定、支承升降貨梯箱體內(nèi)部所有的機(jī)械零件和部分電器元件，主要由側(cè)板、連接管和連接片等零件焊接而成，材料均選 用，其中兩側(cè)板的厚度，同時(shí)為了減輕支架的重量，在兩側(cè)板上設(shè)計(jì)了很多工藝孔。蝸輪蝸桿由于蝸輪蝸桿機(jī)構(gòu)具有傳動(dòng)比大、結(jié)構(gòu)緊湊、沖擊載荷小、傳動(dòng)平穩(wěn)和 噪聲低等優(yōu)點(diǎn)，并具有反向自鎖的特性。可以保證搬運(yùn)患者過(guò)程中，電動(dòng)機(jī)斷電時(shí)傳動(dòng)機(jī)構(gòu)能夠自鎖，故選用蝸輪蝸桿減速器。采用漸開(kāi)線蝸桿，材料為鋼，對(duì)其螺 旋面進(jìn)行淬火處理，以提高傳動(dòng)效率和增加耐磨性，蝸輪材料選用聚甲醛。塑料蝸輪具有加工經(jīng)濟(jì)性好、傳動(dòng)平穩(wěn)、吸振降噪、質(zhì)量輕、耐磨和自潤(rùn)滑等優(yōu)點(diǎn)，使得 升降貨梯的設(shè)計(jì)更加人性化。
Selection of enclosed gear drives, large and small gears are made of steel, after quenching, are soft tooth surface, due to the closed soft tooth surface gear common failure mode for the tooth surface pitting, so by the time the tooth surface contact fatigue design strength calculation, according to the tooth root bending fatigue strength to be checked. Bracket Bracket for fixing,supporting cargo lift all the mechanical parts inside the box and some electrical components, mainly by side, connecting pipes and welded parts such as connecting pieces, materials are selected,the thickness of which both sides of the plate, and in order reduce the weight of the stent, on both sides of the board designed a lot of craft holes. Since the worm worm mechanism having a transmission ratio, compact, impact load is small, smooth transmission and low noise advantages, and has a reverse self-locking feature. You can ensure that the process handling patients, when the motor is de-energized transmission mechanism can be self-locking, so the selection of worm gear reducer. Involute worm, materials for steel, quenching its helical surface, in order to improve transmission efficiency and increase wear resistance, worm material selection POM. Plastic Worm has processed the economy is good, smooth transmission, absorbing vibration noise, light weight,wear-resistant and self-lubricating, etc., so that cargo lifter design more humane.

升降貨梯http://www.jntr168.com/導(dǎo)向機(jī)構(gòu)主要由導(dǎo)向塑料管、導(dǎo)向支架、壓縮彈簧、安全塞、導(dǎo)向外殼和導(dǎo)向軸等零件組成，為導(dǎo)向機(jī)構(gòu)的半剖視，兩個(gè)導(dǎo)向塑料管之間形成一個(gè)窄縫，升 降布帶從這個(gè)窄縫中伸出箱體，防止布帶卷亂，起到導(dǎo)向的作用。安全塞由導(dǎo)向支架和壓縮彈簧支承，為了防止壓縮彈簧受力后失去穩(wěn)定性，在安全塞上設(shè)計(jì)了一個(gè) 小導(dǎo)桿，小導(dǎo)桿與彈簧間的間隙參照表進(jìn)行設(shè)計(jì)。吊臂軸焊接而成，兩端分別安裝一個(gè)吊臂掛鉤，材料選用，進(jìn)行調(diào)質(zhì)處理，與箱體下殼的掛鉤一起構(gòu)成三個(gè)懸吊 點(diǎn)，通過(guò)軟支承吊具將被升降者吊起，吊臂的承重量，為了使被升降者在乘坐時(shí)能夠處于舒適狀態(tài)，兩吊臂掛鉤間距參照表列出了水平尺寸的相關(guān)數(shù)據(jù)作為設(shè)計(jì)參考，平衡桿用來(lái)保持升降裝置的平衡，材料設(shè)計(jì)成空心管狀，減輕了吊臂整體的重量。
Guiding mechanism mainly consists of a plastic tube guide, guide bracket, compression springs, safety plug, guide housing and the guide shafts and other parts for the semi-sectional view of the guide mechanism is formed between the two guide a narrow plastic tube, lifting the cloth belt from this narrow protrude box, cloth strap to prevent chaos, play a guiding role. Safety plug from the guide bracket and the compression spring is supported, in order to prevent the destabilization of the force of the compression spring, the safety plug is designed in a small guide bar, a small gap between the guide bar and the spring is designed with reference to the table. Boom shaft welded ends were to install a crane hook, material selection, quenching and tempering treatment, with the hook under the shell casing together constitute the three suspension points, supported by soft lift spreader who will be lifted , bearing the weight of the boom, in order to be able to lift those at the ride in a comfortable state, two crane hook spacing data reference table lists the horizontal dimension as a design reference, balance bar lifting device used to maintain balance, materials designed as a hollow tube, to reduce the overall weight of the boom.
