中國地質(zhì)大學(xué)長城學(xué)院 本科 畢業(yè)設(shè)計 外文資料翻譯 系 別 ： 工程技術(shù)系 專 業(yè) ： 機械設(shè)計制造及其自動化 姓 名 ： 劉旭鵬 學(xué) 號 ： 05211522 2015 年 1 月 20 日 1 外文資料翻譯譯文 全封閉單托輥帶式輸送機是有撓性輸送帶作為物料承載件和牽引件的連續(xù)輸送全封閉設(shè)備，根據(jù)摩擦原理，由傳動滾筒帶動輸送帶，可以再水平方向和傾斜不大的方向運送散碎物 品，其特點是結(jié)構(gòu)全封閉、輸送能力大、功耗小、結(jié)構(gòu)簡單、維修方便、費用低、對物料實用性強、用途廣泛，是一種理想的輸送機械，在糧食流通，倉儲領(lǐng)域里有大量的應(yīng)用。根據(jù)輸送工藝要求，單托輥全封閉帶式輸送機可以單臺輸送，也可多臺組成或與其他輸送設(shè)備組成水平或傾斜的輸送系統(tǒng)，以滿足不同布置形式的作業(yè)線需要。該設(shè)備可在環(huán)境溫度 -20至 +40范圍內(nèi)使用，輸送物料的溫度在 50以下。 全封閉單托輥帶式輸送機由機頭部分、機身部分、機尾部分、輸送帶和現(xiàn)場安全裝置組成。（ 1）、機頭部分是進行運輸作業(yè)的核心部位，主要包括電動機、 減速機、液力耦合器、聯(lián)軸器、主傳動滾筒、清掃器和機頭架等裝置。皮帶機頭部主要為物流運輸提供動力，通過滾筒來作為運輸動力來完成物料的運送。 （ 2）、機身部分包括托輥、機架等，用于帶動和支撐輸送皮帶。在帶式輸送機中，托輥的作用是支撐輸送帶、減少輸送帶運動阻力，并使輸送帶的垂度不超過一定限度，以保證運送帶平穩(wěn)運行。機架是運輸機的支撐架，用于支撐托輥、輸送帶，以保證膠帶運輸機的正常運行。輸送機的機架類型由輸送機的類型決定。（ 3）、皮帶運輸機機尾一般由殼體、軸承、無擋邊空心筒式從動輥和張緊裝置 4大部分組成。 針 對普通托輥輸送機在實際使用過程中的缺點，我們重點在單托輥的設(shè)計、喂料斗的設(shè)計、清掃回料裝置的設(shè)計、張緊裝置的設(shè)計以及密封結(jié)構(gòu)的設(shè)計等方面做了優(yōu)化創(chuàng)新，以延長皮帶機配件的使用壽命、增加皮帶機運行的穩(wěn)定性以及強化整機的密封性。傳統(tǒng)的皮帶輸送機設(shè)計理念是皮帶和托輥的線速度一致，皮帶和托輥摩擦力小，因此，傳統(tǒng)皮帶輸送機在同一軸上的托輥直徑是一致的，新的單托輥皮帶輸送機設(shè)計理念認(rèn)為在同一軸上的托輥直徑可以不一致，這種設(shè)計理念的創(chuàng)新帶來了皮帶輸送機的革命。 單托輥旋轉(zhuǎn)所需的力量通過皮帶和托輥的摩擦傳遞給托輥，皮帶和托輥 摩擦力的大小決定單托輥皮帶機的性能。在一定的速度下，皮帶和托輥摩擦力越小，產(chǎn)量越小。在最理想的狀態(tài)下，輸送帶的運行阻力會較小，產(chǎn)量最大。因此，單托輥的創(chuàng)新設(shè)計時間上就是在一定的帶速下合理的選擇托輥的參數(shù)，以達(dá)到最佳的效果。 張緊裝置的設(shè)計也是重點，張緊裝置的作用一是保證輸送帶有足夠的張力，使?jié)L筒與輸送帶之間產(chǎn)生必要的的摩擦力；二是限制輸送帶在各支撐托輥間的垂度，使膠帶輸送機能正常工作。密封裝置的主要作用是防風(fēng)、雨、防止揚塵和物料流失。在改進后的單托輥皮帶機設(shè)計中，采取了全封閉式結(jié)構(gòu)，極大地改善了現(xiàn)場工作環(huán)境 ，配合外部除塵風(fēng)網(wǎng)的設(shè)置，全封閉型單托輥皮帶機可適應(yīng)露天作業(yè)環(huán)境及對環(huán)境污染要求很高的作業(yè)區(qū)域。 輸送機的運行過程中，要及時檢查托輥，發(fā)現(xiàn)托輥損壞或者轉(zhuǎn)動不靈活要及時更換，保證輸送機完好的工作狀態(tài)；發(fā)現(xiàn)輸送機輸送帶跑偏時要及時糾正，使帶式輸送機保持良好的運行狀態(tài)。加強現(xiàn)場管理，嚴(yán)格作業(yè)機制，認(rèn)真執(zhí)行設(shè)備維護規(guī)范中的檢查要求。 我國帶式輸送機應(yīng)用范圍較廣，可用于多種干濕粉狀，粒狀，塊狀物料的運輸傳送，運送量達(dá)，運送距離較長，運行阻力小，能量消耗地，受地形條件限制小，在途中可裝卸貨物，操作簡單，運行平穩(wěn)，易維修 ；但膠帶易受磨損，且坡度不能太大，摩擦力大 ，且運送粉粒狀物料易污染環(huán)境，所以這個設(shè)計能減少環(huán)境的污染，并 減少摩擦避免膠帶的過 2 度磨損。 同時我國的輸送機發(fā)展水平有了明顯的提高，大功率，長距離的帶式運輸機的新產(chǎn)品開發(fā)和新技術(shù)的研究都取得了不錯的成就。所以帶式輸送機是最理想的高效連續(xù)運輸設(shè)備，與其他設(shè)備相比具有明顯的優(yōu)勢。故不僅可以在短距離運輸內(nèi)使用，也可以在長距離輸送中使用。所以在生產(chǎn)環(huán)節(jié)的連續(xù)性和自動化中起到了極其重要的作用，提高了勞動生產(chǎn)率。 近年來我國帶式輸送機有很大發(fā)展，在新產(chǎn)品開發(fā)上取得了不錯的成績。輸 送機系列產(chǎn)品越來越多，產(chǎn)量多，批次大，并對輸送機 的關(guān)鍵技術(shù)及其主要部件進行了理論研究和產(chǎn)品開發(fā) 。但在很多方面還有不足，跟國外相比，裝機功率小，運輸能力差，并且最大輸送帶寬度小，工作面運輸長度僅為國外的一半，可靠性和壽命上也有不小的差距，所以本次設(shè)計不能解決輸送機的所有問題，但能在一定程度上改善輸送機現(xiàn)狀。 隨著我國帶式輸送機的發(fā)展，以廣泛應(yīng)用于各個部門。我國對普通帶式輸送機進行改進，完善相應(yīng)結(jié)構(gòu)，首先用單托輥固定皮帶防止跑偏。同時，在運輸機外加防護罩，防止對環(huán)境造成污染。再次螺旋加緊裝置保證機器運行的可靠性 和平穩(wěn)性。這些能在一定程度上保證帶式輸送機的性能，使其帶速快，運送量達(dá)，高效節(jié)能環(huán)保。使輸送物料種類更加廣泛，輸送能力范圍更加寬廣，輸送的適應(yīng)性更強，裝卸更加靈活，可靠性安全性高，有良好的發(fā)展前景。 全封閉單托輥帶式輸送機優(yōu)點是全封閉結(jié)構(gòu)、防雨性能良好、粉塵不外揚、環(huán)保性能好，運動部件包括托輥的軸承全部外露易于檢修維護，尾部回料裝置能自動收集散落在下皮帶上的物料自動返回到上皮帶中。由于皮帶機的輸送帶根據(jù)摩擦傳動原理運動，具有輸送量大、輸送距離長、輸送平穩(wěn)、物料與輸送帶沒有相對運動、噪音較小、結(jié)構(gòu)簡單、維修方 便、能量消耗少、部件標(biāo)準(zhǔn)化等優(yōu)點，因而皮帶機廣泛應(yīng)用于采礦、冶金、化工、鑄造、建材等行業(yè)的輸送和生產(chǎn)流水線以及水電站建設(shè)工地和港口等部門，用來輸送松散物料。通過以上各個部件的創(chuàng)新設(shè)計，將大大提高工作效率，減低損耗，提高設(shè)備運行穩(wěn)定性，改善作業(yè)環(huán)境。通過不斷完善和創(chuàng)新，有利于提升全封閉單托輥皮帶輸送機的產(chǎn)品檔次和應(yīng)用范圍。 3 外文原文 Single roller belt conveyor is totally enclosed with flexible conveyor belt as material ChengZaiJian and drawing a continuous conveyor totally enclosed equipment, according to the principle of friction, driven by drive roller conveyor belt, horizontal direction and the direction of the tilt is again shipping bulk items, its characteristic is fully enclosed structure, large conveying capacity, low consumption, simple structure, easy maintenance, low cost, strong practicability, widely used for the material, is a kind of ideal conveying machinery, in the grain circulation, storage areas have a large number of applications. According to the conveying process requirements, single roller closed belt conveyor can be a single delivery, can also be more than one component or with other conveying equipment to form horizontal or inclined conveyor system, in order to satisfy different layout of production line. The device can be in the environment temperature from 20 to + 40 within the scope of use, the temperature of the conveying material under 50 . Fully enclosed by the single roller belt conveyor head part, fuselage, tail section, conveyor belt and site safety device. (1), the nose section is the core part of transport operations, including motor, reducer, hydraulic coupling, coupling, main drive roller, sweeper and headstock gear. Belt nose department is mainly to provide power for logistics, transportation by drum as a driving force to complete the material delivery. (2), body parts including roller, frame, etc., used to drive and support the conveyor belt. In belt conveyor, roller conveyor belts role is to support, to reduce drag conveyor belt movement, and makes the conveyor belt of the sag does not exceed a certain limit, to ensure the transport belt running smoothly. Rack is conveyor support frame, used to support roller, conveyor belt, to ensure the normal operation of belt conveyor. Conveyor frame type determined by the type of conveyor. (3), general by shell, bearing, the belt conveyer tail no guard hollow cylinder driven roller and tensioning device. For common faults in the process of roller conveyor in actual use, we focus on single roller design, the design of the feeding hopper, cleaning device back design, the design of the tensioning device, and the design of the sealing structure has been optimized in aspects of innovation, in order to prolong the service life of belt conveyor accessories, increase belt chance the stability and reinforcement of sealing machine. The traditional belt conveyor design concept is belt and rollers linear velocity is consistent, belt and roller friction small, therefore, the traditional belt conveyor roller on the same shaft diameter is consistent, the new single roller belt conveyor design idea think on the same shaft roller diameter can be inconsistent, the design concept of innovation has brought the revolution of belt conveyor. Single roller rotation of power needed by the belt and roller friction is passed to the roller, the size of the belt and roller friction decides the performance of the single roller belt conveyor. Under a certain speed, belt and roller friction is smaller, the smaller the output. Under the ideal condition, the conveyor belt running resistance will be smaller, the largest output. Therefore, the innovation of the single roller design in time is the reasonable choice under the certain tape speed of roller parameters, in order to achieve the best effect. Tensioning device design is the key, the role of the tensioning device is a guaranteed supply with enough tension, to produce the necessary friction between roller and the conveyer belt; Second is to limit the conveyor belt between the supporting roller sag, make tape transfer function to work properly. The main purpose of the sealing device is wind, rain, prevent dust emission and material 4 loss. In the improved design of the single roller belt conveyor, adopted a fully enclosed structure, greatly improved the working environment, with external wind dust network Settings, full enclosed the single roller belt conveyor can meet the requirements for open working environment and pollution to the environment very high operational areas. Conveyor are running, to check the roller in time, found that the roller damage or rotation is not flexible to change in time, ensure the conveyor in good working condition; Found to rectify the conveyor belt running deviation, make the belt conveyor to keep good running state. Strengthen field management, strict operation mechanism, seriously implement equipment maintenance inspection requirements in the specification. Belt conveyor in our country has a wide application range, can be used for a variety of wet and dry powder, granule, block material transportation, transport volume, transport distance is long, little resistance during operation, energy consumption, small restricted by terrain conditions, on the way to loading and unloading of goods, simple operation, stable operation, easy maintenance; But tape are susceptible to wear and tear, and the slope is not too big, high friction, easy to pollute the environment and transporting powdery and granular materials, so this design can reduce the environment pollution, and reduce the friction to avoid excessive wear of belt. At the same time in developing the conveyor level have obvious improve, high power, long distance belt conveyor of new technology and new product development research have made great achievements. The belt conveyor is one of the most ideal efficient continuous transportation equipment, compared with other equipment has obvious advantages. Therefore, not only can be used in short distance transportation, also can be used in long distance transmission. So in the continuity of production and has played a very important role in automation, improve the labor productivity. Conveyor series products is becoming more and more production, more batch is big, and the key technologies of conveyor and its main part has carried on the theoretical research and product development. But there are still insufficient in many ways, compared with abroad, installed power is small, transport capacity is poor, and the largest conveyor belt width is small, face only half as much as that of the foreign transport length has a big gap between the reliability and life expectancy, so the design cant solve all problems of conveyor, but it does to a certain extent, improve the state of conveyor. With the development of belt conveyor in our country, is widely applied in each department. To improve the ordinary belt conveyor in our country, perfect the corresponding structure, first of all with a single roller fixed belt prevent running deviation. At the same time, the conveyor plus a shield to prevent damage to the environment. Again, screw tightening device ensure machine operation reliability and stability. To some extent, these can guarantee the performance of the belt conveyor, the belt speed is fast, transport volume, high efficiency and energy saving environmental protection. Make more widely conveying material sort, wider scope of transmission capacity, transmission of stronger adaptability, loading and unloading is more flexible, high safety reliability, with good prospects for development. Totally enclosed the single roller belt conveyor is fully enclosed structure, the waterproof performance is good, dust not in public, environmental protection performance is good, the moving parts including roller
