12、;<p>　　在后來(lái)，天車(chē)一詞進(jìn)入人類的眼中。橋式起重機(jī)是橋架在高架軌道上運(yùn)行的一種橋架型起重機(jī)，又稱天車(chē)。橋式起重機(jī)的橋架沿鋪設(shè)在兩側(cè)高架上的軌道縱向運(yùn)行，起重小車(chē)沿鋪設(shè)在橋架上的軌道橫向運(yùn)行，構(gòu)成一矩形的工作范圍，就可以充分利用橋架下面的空間吊運(yùn)物料，不受地面設(shè)備的阻礙。 </p><p>　　橋式起重機(jī)廣泛地應(yīng)用在室內(nèi)外倉(cāng)庫(kù)、廠房、碼頭和露天貯料場(chǎng)等處。橋式起重機(jī)可分為普通橋式起重機(jī)、簡(jiǎn)易粱橋

13、式起重機(jī)和冶金專用橋式起重機(jī)三種。</p><p>　　普通橋式起重機(jī)一般由起重小車(chē)、橋架運(yùn)行機(jī)構(gòu)、橋架金屬結(jié)構(gòu)組成。起重小車(chē)又由起升機(jī)構(gòu)、小車(chē)運(yùn)行機(jī)構(gòu)和小車(chē)架三部分組成。起升機(jī)構(gòu)包括電動(dòng)機(jī)、制動(dòng)器、減速器、卷筒和滑輪組。電動(dòng)機(jī)通過(guò)減速器，帶動(dòng)卷筒轉(zhuǎn)動(dòng)，使鋼絲繩繞上卷筒或從卷筒放下，以升降重物。小車(chē)架是支托和安裝起升機(jī)構(gòu)和小車(chē)運(yùn)行機(jī)構(gòu)等部件的機(jī)架，通常為焊接結(jié)構(gòu)。 </p><p>　　起

14、重機(jī)運(yùn)行機(jī)構(gòu)的驅(qū)動(dòng)方式可分為兩大類：一類為集中驅(qū)動(dòng)，即用一臺(tái)電動(dòng)機(jī)帶動(dòng)長(zhǎng)傳動(dòng)軸驅(qū)動(dòng)兩邊的主動(dòng)車(chē)輪；另一類為分別驅(qū)動(dòng)、即兩邊的主動(dòng)車(chē)輪各用一臺(tái)電動(dòng)機(jī)驅(qū)動(dòng)。中、小型橋式起重機(jī)較多采用制動(dòng)器、減速器和電動(dòng)機(jī)組合成一體的“三合一”驅(qū)動(dòng)方式，大起重量的普通橋式起重機(jī)為便于安裝和調(diào)整，驅(qū)動(dòng)裝置常采用萬(wàn)向聯(lián)軸器。 </p><p>　　起重機(jī)運(yùn)行機(jī)構(gòu)一般只用四個(gè)主動(dòng)和從動(dòng)車(chē)輪，如果起重量很大，常用增加車(chē)輪的辦法來(lái)降低輪壓。當(dāng)車(chē)

15、輪超過(guò)四個(gè)時(shí)，必須采用鉸接均衡車(chē)架裝置，使起重機(jī)的載荷均勻地分布在各車(chē)輪上。 </p><p>　　橋架的金屬結(jié)構(gòu)由主粱和端粱組成，分為單主粱橋架和雙粱橋架兩類。單主粱橋架由單根主粱和位于跨度兩邊的端粱組成，雙粱橋架由兩根主粱和端粱組成。 </p><p>　　主粱與端粱剛性連接，端粱兩端裝有車(chē)輪，用以支承橋架在高架上運(yùn)行。主粱上焊有軌道，供起重小車(chē)運(yùn)行。橋架主粱的結(jié)構(gòu)類型較多比較典型的有

18、桁架表面鋪有走臺(tái)板，起重機(jī)運(yùn)行機(jī)構(gòu)及電氣設(shè)備裝在橋架內(nèi)部，自重較輕，整體剛度大，這在中國(guó)是較為廣泛采用的一種型式。 </p><p>　　普通橋式起重機(jī)主要采用電力驅(qū)動(dòng)，一般是在司機(jī)室內(nèi)操縱，也有遠(yuǎn)距離控制的。起重量可達(dá)五百噸，跨度可達(dá)60米。簡(jiǎn)易梁橋式起重機(jī)又稱粱式起重機(jī)，其結(jié)構(gòu)組成與普通橋式起重機(jī)類似，起重量、跨度和工作速度均較小。橋架主粱是由工字鋼或其他型鋼和板鋼組成的簡(jiǎn)單截面粱，用手拉葫蘆或電動(dòng)葫蘆配上簡(jiǎn)

19、易小車(chē)作為起重小車(chē)，小車(chē)一般在工字粱的下翼緣上運(yùn)行。橋架可以沿高架上的軌道運(yùn)行，也可沿懸吊在高架下面的軌道運(yùn)行，這種起重機(jī)稱為懸掛粱式起重機(jī)。</p><p><b>　　外文原文</b></p><p>　　The winch is also known as the winch, mainly used in construction, water conserv
