f the highrise building needs, while Jiangsu Haimen third machinery factory the introduction of patented technology developed a series of multiple rows of hoist rod peristaltic transmission is divided into three series: control, hand control and puter control three kinds big, its performance is better than the international advanced training platform Pacific Seibu type hoist, building hoist technology in China cross the advanced ranks in the world. Expert opinion in 1991 October through the provincial science and Technology Commission, the anization: the product bination is reasonable, pact structure, light weight, strong overload capacity, safe and reliable work, pared with similar products, the domestic advanced level, the design of transmission part of the unique, novel, uniform stress, reasonable, is the first at home and abroad.Hoist for monly used in domestic and abroad building, posed of motor, brake, generally have independent gear box, cable reel, chassis etc.. Gear box they usually adopts the heavy gear or worm gear reducer, motor and reducer, the installation form of rope drum are generally n, J, etc.. The mon problems are: large volume, poor overload capacity, large noise, low efficiency, short service life, work is not safe, some products have been included in the national phaseout products. Hoist design at home and abroad are trying to reduce the volume, reduce weight, improve the bearing capacity, saving energy, work safety Rely on, but are not the ideal choice of the reel internal accumulation 西京學(xué)院本科畢業(yè)設(shè)計(論文)35speed reducer drive, and make the design, trial production difficulties. Stocky series hoist adopts multiple rows of push rods wriggling reducer, and the reducer is directly arranged on the reel, make the design of the winch to small size, light weight, high overload capacity, energy saving, safe and reliable. Its structure is: by the decelerating device hidden in the cable reel the rope drum, left and right bracket, the chassis and the conical braking motor was a font settings, convenient installation and transportation, and strive to the best shape structure. The world today is science and technology make a spurt of progress of the times, technology updates is change rapidly.We should seize the favorable opportunity, aiming at the international advanced level, from the macro to revise the new construction hoist the national standards, to replace the 86 standard. The main manifestations of technological progress is gradually developed a set of advanced standards for design, production guidance of hoist, the quality of the products is increasing day by day, and the formulation of standards, modify to walk in the design of the front, close to the world advanced level, in order to promote constantly update our construction hoisting machine technology, continuous development. The manufacturers should timely grasp of market dynamics, the timely introduction of advanced technology. Market petition is actually the petition of science and technology, Deng Xiaoping Theory and the science and technology is the first productivity is being tested by the practice, and confirmed by practice. Our pany only has to update existing technology, can remain invincible, no longer let like the old J type hoist rule all the land for decades behind again.西京學(xué)院本科畢業(yè)設(shè)計(論文)36翻譯原文:卷揚(yáng)機(jī)又稱之為絞車。工作原理:由人力或機(jī)械動力驅(qū)動卷筒、卷繞繩索來完成牽引工作的裝置。垂直提升、水平或傾斜曳引重物的簡單起重機(jī)械。分手動和電動兩種,主要以電動為主。 電動卷揚(yáng)機(jī)由電動機(jī)、聯(lián)軸節(jié)、制動器、齒輪箱和卷筒組成,共同安裝在機(jī)架上。電動卷揚(yáng)機(jī)又可稱為電動葫蘆。對于起升高度和裝卸量大,工作繁忙的情況下,要求調(diào)速性能好,特別要空鉤能快速下降。對安裝就位或敏感的物料,要能以微動速度下降。卷揚(yáng)機(jī)包括快速卷揚(yáng)機(jī)和慢速卷揚(yáng)機(jī),僅能在地上使用,它以電動機(jī)為動力,經(jīng)彈性聯(lián)軸節(jié),三級封閉式齒輪減速器,牙嵌式聯(lián)軸節(jié)驅(qū)動卷筒,采用電磁制動。該產(chǎn)品通用性高、結(jié)構(gòu)緊湊、體積小、重量輕、起重大、使用轉(zhuǎn)移方便,被廣泛應(yīng)用于建筑、水利工程、林業(yè)、礦山、碼頭等的物料升降或平拖,還可作現(xiàn)代化電控自動作業(yè)線的配套設(shè)備。我國的建筑卷揚(yáng)機(jī)生產(chǎn)已有近 40 年的歷史,而真正定型生產(chǎn)是在 70 年代初的事。80 年代初我國的建筑卷揚(yáng)機(jī)動技術(shù)的研究才活躍起來,但和國外的建筑卷揚(yáng)機(jī)技術(shù)相比落生至少 30 年,我國目前生產(chǎn)使用的建筑卷揚(yáng)機(jī)還是 70 年代定型的產(chǎn)品。在 80 后代以前,我國還沒有制定有關(guān)建筑卷揚(yáng)機(jī)的國家標(biāo)準(zhǔn),也缺少建筑卷揚(yáng)機(jī)的設(shè)計、試驗、生產(chǎn)、使用規(guī)范。全國處于無標(biāo)準(zhǔn)可循,呈現(xiàn)出放任自流狀態(tài),產(chǎn)品規(guī)格五花八門,結(jié)構(gòu)與技術(shù)基本上維持根據(jù)日本 JIS800l 等 40 年代落后標(biāo)準(zhǔn)及按蘇聯(lián)圖紙制造的 1011012 等落后機(jī)型,進(jìn)展十分緩慢。80 年代以后,各種競爭機(jī)制的引入,科技是第一生產(chǎn)力的概念逐漸被人們所認(rèn)識,所接受。是我國建筑卷揚(yáng)機(jī)設(shè)計制造技術(shù)發(fā)展最快的時期。國家也制定了有關(guān)建筑卷揚(yáng)機(jī)的配套標(biāo)準(zhǔn)、規(guī)范。新產(chǎn)品種數(shù)近十個,其中最具有代表性的產(chǎn)品有福建省建筑機(jī)械廠的行星傳動卷揚(yáng)機(jī)、昆明建筑機(jī)械廠的少齒差傳動卷揚(yáng)機(jī)、長沙建筑機(jī)械研究所與福州市建筑機(jī)械廠聯(lián)合開發(fā)的仿日本 Seibu 公司采用立式齒輪傳動的電控卷揚(yáng)機(jī).廣州市一建公司機(jī)械廠的高速卷揚(yáng)機(jī)適應(yīng)高層建筑的多功能需要,而江蘇海門第三機(jī)械廠引進(jìn)專利技術(shù)開發(fā)的系列多排頂桿蠕動傳動的卷揚(yáng)機(jī)分為三西京學(xué)院本科畢業(yè)設(shè)計(論文)37大系列:即電控、手控和微機(jī)程控三大類,其練臺性能優(yōu)于代表國際先進(jìn)承平的Seibu 一字型卷揚(yáng)機(jī),使我國的建筑卷揚(yáng)機(jī)技術(shù)跨人世界先進(jìn)行列。1991 年 10 月通過的省科委組織的專家鑒定意見:該產(chǎn)品整機(jī)組合合理、結(jié)構(gòu)緊湊、重量輕、過載能力強(qiáng)、工作安全可靠,與同類產(chǎn)品相比,居國內(nèi)先進(jìn)水平,其中傳動方式部分的設(shè)計構(gòu)思獨(dú)特、新穎,受力均勻、合理,屬國內(nèi)外首創(chuàng)。 目前國內(nèi)外廣泛使用的建筑用卷揚(yáng)機(jī),一般均有電機(jī)、制動器、獨(dú)立的減速箱、鋼繩卷筒、底架等組成。它們的減速箱通常采用笨重的齒輪減速箱或蝸輪蝸桿減速箱,電機(jī)與減速箱、鋼繩卷筒的安裝形式一般有“n 型、 J”型、型等。普遍存在的不足是:體積大、過載能力差、噪音大、效率低、使用壽命短、工作不夠安全可靠等,有些產(chǎn)品還已列入國家淘汰產(chǎn)品。國內(nèi)外的卷揚(yáng)機(jī)設(shè)計都在致力于縮小體積、減輕重量,提高承載能力,節(jié)省能源,工作安全可靠,但都沒有理想的可供選擇的卷筒內(nèi)藏減速傳動裝置,而使設(shè)計、試制工作遇到困難。Stocky 系列卷揚(yáng)機(jī)采用多排頂桿蠕動減速裝置,并將該減速裝置直接設(shè)置于卷筒內(nèi),使設(shè)計的卷揚(yáng)機(jī)達(dá)到體積小、重量輕、過載能力大、節(jié)省能源、工作安全可靠。它的結(jié)構(gòu)是:由減速裝置內(nèi)藏于鋼繩卷筒內(nèi)的鋼繩卷筒、左右支架、底架及錐形制動電機(jī)呈一字型設(shè)置,便于安裝運(yùn)輸,力求最佳外型結(jié)構(gòu)形式。當(dāng)今世界是科技突飛猛進(jìn)的時代,技術(shù)的更新更是日新月異。 我們應(yīng)該把握有利時機(jī),瞄準(zhǔn)國際先進(jìn)水平,從宏觀上及時修訂新的建筑卷揚(yáng)機(jī)國家標(biāo)準(zhǔn),以替代 86 標(biāo)準(zhǔn)。技術(shù)進(jìn)步的主要表現(xiàn)是逐步制訂一整套先進(jìn)標(biāo)準(zhǔn),用于指導(dǎo)卷揚(yáng)機(jī)的設(shè)計生產(chǎn),使產(chǎn)品質(zhì)量日益提高,且標(biāo)準(zhǔn)的制訂、修改盡量地走在設(shè)計的前頭,向世界先進(jìn)水平靠攏,以促進(jìn)我國的建筑卷揚(yáng)機(jī)技術(shù)不斷更新,不斷發(fā)展。生產(chǎn)廠家應(yīng)該及時掌握市場動態(tài),及時引進(jìn)先進(jìn)技術(shù)。市場的競爭實際上是科技的競爭,鄧小平的“科學(xué)技術(shù)是第一生產(chǎn)力”的理論越來越被實踐所檢驗,并由實踐得到證實。我們的企業(yè)只有不斷更新現(xiàn)有技術(shù),才能立于不敗之地,再也不能讓像老式“J”型卷揚(yáng)機(jī)一統(tǒng)天下幾十年的落后狀態(tài)重現(xiàn)。西京學(xué)院本科畢業(yè)設(shè)計(論文)38附錄二The widely applied in construction, water conservancy, metallurgy, lifting operation.

Electric hoist is posed of motor, coupling, brake, gear box and reels, mounted on the frame. Electric hoist is also known as electric hoist. For lifting height and loading amount is large, busy with work, request good speed performance, especially to the empty hook to the rapid decline in.
