For the loading and unloading work in Chinese container ports, we usually choose the coastal container crane and the tyred lift (which is the first choice for the rear yard). The track lift was only used some yards for it was much fallen behind the present port machinery requirements, such as work level, electric control system, handing system, so it can not meet the requirements of container loading and unloading in modern ports. 軌跡吊與輪胎吊的對(duì)比 Comparison between track lift and tyred lift 2.1 外形尺度 Outline Dimension 受輪胎的承載力、整機(jī)跑偏等疑問(wèn)的約束,在現(xiàn)在條件下,輪胎吊的外型尺度已不太也許再有大的打破,通?缇嗖怀23.47
m(6列集裝箱加1條車道),堆高不超越18. 2 m(堆5過(guò)6)。而軌跡吊的跨距可達(dá)40
m(12列集裝箱)以上,只需堆場(chǎng)承載才能滿足,堆高可超越7一8層,且軌跡吊還可有外伸。因而軌跡吊的場(chǎng)所利用率要高于輪胎吊。 For the limits of carrying capacity of tires, machine deviation,etc, the outline dimension of tyred lift can not be improved at present , the general parameters are:span≦23.4m,( 6 containers plus 1lane), pile height≤18.2(5-6). But the span of track lift can be above 40 meters(12containers), and pile height can be above 7-8 layers, and extension included, so the place utilization rate of track lift is much higher that of tyred lift. 2.2 本錢剖析 Cost analysis 現(xiàn)在,在軌距、速度等技能參數(shù)相一起,2種設(shè)備的收購(gòu)報(bào)價(jià)相差不大,軌跡吊略低。關(guān)于碼頭的請(qǐng)求,軌跡吊可選用較多車輪,與現(xiàn)在通常為8個(gè)車輪的輪胎吊相比,輪壓低些,但軌跡吊需建配套變電站,鋪設(shè)電纜、軌跡等,堆場(chǎng)建造出資較高. For combing the technological parameters together, such as: gauges,speeds, the bid prices for these two kinds of cranes are more or less. According to requests from the port, the track lift can select more wheels ,compared with the tyred lift( usually 8 tyres), it has less wheel pressure. But the track lift needs supported transformer substation,cable laying,track, so the yard construction cost is comparatively higher. 在運(yùn)轉(zhuǎn)中,軌跡吊通過(guò)電網(wǎng)直接用電,而輪胎吊則必須用自帶柴油機(jī)發(fā)電,在完結(jié)一樣動(dòng)作、耗費(fèi)一樣能量的狀況下,直接從電網(wǎng)用電比自行發(fā)電本錢低。別的,
輪胎吊處于等待狀況時(shí),柴油機(jī)還需損耗部分額外的油料,而軌跡吊在起升組織降低時(shí)還有部分能量反饋到電網(wǎng)。因而,軌跡吊的能耗顯著要低得多,在運(yùn)轉(zhuǎn)本錢上
有較大優(yōu)勢(shì)。 During operation, the power of the track lift is from the electricity grid, but the tyred lift needs an attached diesel electrical machine, so for the same action and power consumption, the cost of power from grid is much less than that supplied by oneself. While the tyred lift is on standby, the diesel electrical machine is still consuming extra diesel, but the track lift could repay some power to the grid while its lifting mechanisms are lowing. So the energy consumption of track lift is much lower and thus a good advantage in operation cost. 輪胎吊選用柴油機(jī),即便是進(jìn)口的柴油機(jī)組也有較高的毛病率,還需求定時(shí)進(jìn)行保護(hù)和大修、小修等,而軌跡吊選用的是電纜卷筒供電,進(jìn)口電纜卷筒廠家通常能夠確保其3 -5年無(wú)毛病運(yùn)轉(zhuǎn)。軌跡吊選用鋼制車輪,壽命基本上能夠確保和整機(jī)一樣,而輪胎吊的輪胎需定時(shí)替換。 The tyred lift selects diesel machinery which needs regular maintenance, reparation,overhaul, and there always be somethings wrong with it even for imported ones. The track lift selects cable drum for power supply which can work without trouble for 3-5years. The track lift selects steel wheel whose life is as long as the whole machinery, while the tyres need replacement if necessary. 2.3 作業(yè)功率 Work efficiency 因?yàn)檐壽E和集裝箱方位相對(duì)固定,軌跡吊節(jié)省了對(duì)箱時(shí)間,功率稍高;輪胎吊的大車常常跑偏,車道和集裝箱方位無(wú)法固定,需求有經(jīng)歷的司機(jī)常常進(jìn)行吊具反轉(zhuǎn)和大車糾偏動(dòng)作,影響作業(yè)功率。現(xiàn)在沒(méi)有呈現(xiàn)很有用的主動(dòng)糾偏體系。 For the positions of the track and containers are comparatively fixed, the track lift saves time in operation on containers with a higher work efficiency. There always be deviation for the tyred lift trolley, and the positions of track and containers are not fixed, all above need an experienced driver operate reverse and correction, thus affects whole work efficiency. There has not been very usually automatic correction system yet. 2.4 主動(dòng)操控和碼頭辦理體系 Automatic operation and port handing system 因?yàn)樵谲壽E上運(yùn)轉(zhuǎn),軌跡吊較簡(jiǎn)略完成整機(jī)狀況的監(jiān)測(cè)定位,可完成多種主動(dòng)、半主動(dòng)操控,進(jìn)步功率。在電控體系進(jìn)一步開(kāi)展的狀況下,將來(lái)軌跡吊有也許開(kāi)展
為不需求駕駛員的無(wú)人堆場(chǎng)體系;而輪胎吊的整機(jī)狀況定位艱難,難以完成主動(dòng)操控;軌跡吊可選用光纖與碼頭中控室通訊,帶廣大,抗干擾才能好,現(xiàn)在技能也比
較老練,輪胎吊只能選用無(wú)線通訊,帶寬窄,抗干擾才能差,現(xiàn)在大都只能單向接納一些箱位等簡(jiǎn)略信息,還難以完結(jié)像岸邊集裝箱起重機(jī)那樣的RCMS體系。另
外,無(wú)線通訊還存在必定的傳輸死角。 單臺(tái)軌跡吊對(duì)應(yīng)的集裝箱密度較大,堆高也較高,需求較高的辦理水平,以避免頻頻翻箱。 For operation on tracks, the track lift can briefly finish position monitoring, active operation, semi-active operation with high efficiency. With the development of electric control system, there would be no man yard system for track lift, the optical fiber can be used between the track lift and the control room for communication with wild bandwidth and anti-interference quality, while the tyred lift can only select wireless communication with narrow bandwidth and worse anti-interference quality for only single direction brief information transmission, so it is hard to install RCMS system used in container cranes. Otherwise there is blind area for wireless communication. For a single track lift , the container density is large, the pile height is higher, thus a higher handing level without turning over is needed. 2.5 安全性和環(huán)境保護(hù) 軌跡吊在軌跡上運(yùn)轉(zhuǎn),不會(huì)跑偏碰箱,而輪胎吊運(yùn)用柴油機(jī)發(fā)電,發(fā)生較大污染和噪聲。 雖然以上疑問(wèn)現(xiàn)在對(duì)港口的影響還不顯著,但從久遠(yuǎn)來(lái)看,這些疑問(wèn)不得不仔細(xì)思考。 2.5 saety and environment protection The track lift travels on tracks without devition while the tyred lift would make more pollution and noise consuming diesel for power. Although all infulueances caused by these problems are not necessaryly worth of attention,they do deserve careful consideration in future. 2.6 轉(zhuǎn)場(chǎng)靈活性 軌跡吊轉(zhuǎn)場(chǎng)艱難,雖然現(xiàn)在大大都軌跡吊技能都對(duì)比老練,但作業(yè)中仍不能掃除發(fā)作毛病的也許性,因而在一條軌跡上至少要裝備2臺(tái)軌跡吊。別的,雖然能夠在
堆場(chǎng)安置上做出組織,但不能徹底掃除因同一條軌跡上發(fā)作突發(fā)事件而需求多臺(tái)軌跡吊一起作業(yè)的狀況。依據(jù)國(guó)外的經(jīng)歷,通常在同一軌跡上都要裝備多臺(tái)軌跡吊。
輪胎吊因?yàn)槟軌蝾l頻轉(zhuǎn)場(chǎng),就沒(méi)有這方面的疑問(wèn)。因而,關(guān)于某些軌跡較短而跨數(shù)較多的堆場(chǎng),軌跡吊并不合適。 2.6 Transition flexibility It is hard for track lift to operate transition easily even of comparitively advanced technology and for the uncertainty of something wrong in operation ,there should be at least 2 spare track lifts ready for use in case of need.Else although there could be alteration to stack yard organization,it is still necessary for some track lifts working together in case of some unavoidable accidents.For experiences abroad, there usually be some track lifts working on the same track.While the tyred lift can operate transition easily thus no problems mentioned above for it.So the track lift is not suitable in conditions of short track and more transitions. 為了增強(qiáng)轉(zhuǎn)場(chǎng)靈活性,軌跡吊也可有幾種轉(zhuǎn)場(chǎng)計(jì)劃,這也是軌跡吊研討的一個(gè)方向。別的,國(guó)外也有在大跨距的軌跡吊跨距內(nèi)再裝備一小跨距軌跡吊的計(jì)劃。 For improving the transition flexibility,there could be some transition plans for track lift thus a discussion direction.There be a foreign plan namely to set a smaller track lift within the track gauge of a big one. 該機(jī)有如下特色: (1)32 m軌距,可放置8列集裝箱和2條車道。 (2)跨距較大,經(jīng)剖析和計(jì)算機(jī)模擬作業(yè)狀況,現(xiàn)選用的兩邊剛性腿的金屬結(jié)構(gòu)方法有對(duì)比好的平衡性。 (3)選用自行式小車驅(qū)動(dòng)方法,即小車的驅(qū)動(dòng)電動(dòng)機(jī)、減速箱、制動(dòng)器等均安裝于小車架上,通過(guò)萬(wàn)向節(jié)傳動(dòng)來(lái)驅(qū)動(dòng)前后4個(gè)車輪。選用這種驅(qū)動(dòng)方法能夠削減保護(hù)替換鋼絲繩的作業(yè)量。 (4)小車軌跡選用進(jìn)口的A65矮軌,它踏面寬、高度低、側(cè)向剛性好,能非常好地接受因?yàn)樾≤嚻笨熊壈l(fā)生的側(cè)向力。 (5)大車運(yùn)轉(zhuǎn)速度較高,選用電動(dòng)機(jī)、減速箱、制動(dòng)器三合一驅(qū)動(dòng)組織,盡量削減傳動(dòng)環(huán)節(jié),從而削減高速運(yùn)轉(zhuǎn)中的磨損和噪聲。車輪是特別設(shè)計(jì)的,增大了踏面寬度和輪緣強(qiáng)度,以應(yīng)對(duì)也許呈現(xiàn)的啃軌疑問(wèn)。 (6)裝備了機(jī)械防搖體系等裝置,以替代原來(lái)場(chǎng)橋上通用的液壓式減搖體系,減小了本錢和保護(hù)作業(yè)量。 (7)選用由專門PLC操控的電纜卷筒,確保卷筒與大車運(yùn)轉(zhuǎn)速度的同步性。還通過(guò)過(guò)電纜坑時(shí)減速的方法來(lái)減緩對(duì)龜纜的沖擊。 (8)選用AB百電氣公司的全變頻溝通調(diào)速驅(qū)動(dòng)體系,確?煽窟\(yùn)轉(zhuǎn)。 Features of the crane: (1) Track gauge for 32m which capable of 8 containers and 2 lanes. (2)For larger span and after analysis and computer simulation of working conditions,a metal structure with rigid legs chosen now has a better balance quality. (3)Seletion of self-propelled driving method manely the driving motor,gearbox,brakes are all installed on the trolley frame, which drives the four wheels by the universal joint.This driving method can reduce the amount of work to protect and replace steel wire rope. (4) A65 short track imported is selected as trolley track ,with wider width,low height,good lateral rigidity,can afford the lateral force caused by trolley skew. (5) The crane tranverses in higher speed, adopted with 3(motor,gearbox,brakes)in 1 driving mechanisums,be trying to reduce transmission process, thus reducing wear and noise in high speed tranversing.The wheels are specially designed with enhanced width and rim strength to deal skew. (6) The hydraulic anti-rolling system on bridge has been replaced by mechanical anti-shake system to reduce the costs and protection work amount. (7)The cable drums contrilled by dedicated PLC are selected to the synchronization tranversing speed of drums and crane. Cable pit deceleration is also used to reduce the impact to cables. (8)Full frequency communication speed drive system by AB company is applied to realise reliable tranversing.
