English Introduction:
The LS-II Pull Cord Switch is a highly efficient emergency stop device designed for bulk material conveying systems, widely used in industries such as metallurgy, coal, cement, power, and chemical plants. Featuring a bidirectional trigger mechanism, it allows immediate shutdown from either side of the conveyor via a steel rope, ensuring rapid response during emergencies to safeguard equipment and personnel. Its compact design enables flexible installation on belt conveyors, bucket elevators, and stacker-reclaimer systems.
Constructed with stainless steel dual bearings, the LS-II reduces mechanical wear for extended durability. The housing is treated with anti-corrosion coating, suitable for harsh environments. Equipped with a high-sensitivity microswitch, it achieves a response time of just 2 milliseconds for reliable signal transmission. Available in auto-reset (Type I) and manual-reset (Type II) versions to meet diverse operational needs.

Key Advantages:
The LS-II stands out for its robust construction, featuring die-cast aluminum or stainless steel housing with IP67 protection against water and dust. Its rotary cam mechanism prevents jamming, with an actuation angle of 30° and maximum limit of 75° for smooth operation. Pre-assembled with plastic-coated steel ropes and mounting brackets, it supports installations up to 40 meters apart, while adjustable loops simplify tension management.
應(yīng)用場景
該產(chǎn)品適用于輸送機(jī)沿線緊急停機(jī)保護(hù),尤其在傾斜段或長距離輸送系統(tǒng)中表現(xiàn)優(yōu)異。例如,在礦山和水泥廠中,LS-II可快速切斷故障設(shè)備電源,避免物料堆積或機(jī)械損壞。其模塊化設(shè)計(jì)也便于集成到自動(dòng)化控制系統(tǒng),提升整體安全性。
Applications:
Ideal for emergency stops along conveyors, the LS-II excels in inclined or long-distance systems. In mining or cement plants, it swiftly cuts power during failures to prevent material spills or equipment damage. Its modular design also facilitates integration into automated control systems for enhanced safety.

拉繩開關(guān)(Pull Cord Switch)俗稱“緊急停機(jī)開關(guān)”。作用于帶式輸送現(xiàn)場需要停機(jī)時(shí),通過開關(guān)動(dòng)作使輸送機(jī)停機(jī)。
適用范圍:
拉繩開關(guān)廣泛用于冶金、煤炭、水泥、采礦、電力、港埠、化工等域的各種專門從事散料輸送的輸送設(shè)備。
簡介
拉繩開關(guān)分為手動(dòng)復(fù)位和自動(dòng)復(fù)位兩種,需要達(dá)到國家規(guī)定IP等級(jí)。
自動(dòng)復(fù)位:動(dòng)作后后能自動(dòng)回到初始位置,可能會(huì)造成誤差啟動(dòng)。
手動(dòng)復(fù)位:動(dòng)作后有自鎖裝置能保持在操作位置上,需要手動(dòng)操作復(fù)位手柄可使其返回初始位置。
拉繩開關(guān)是帶式輸送機(jī)必備的安全保護(hù)裝置,防止事故的擴(kuò)大而帶來重大損失。由于安裝方便,開關(guān)轉(zhuǎn)換可靠,在帶式運(yùn)輸現(xiàn)場得到廣泛的應(yīng)用。
結(jié)構(gòu)和基本原理
拉繩開關(guān)由拉桿、復(fù)位柄、凸輪、鎖槽及微動(dòng)開關(guān)等組成。
拉繩開關(guān)安裝于皮帶輸送機(jī)的兩側(cè)的機(jī)架上,用鋼絲繩沿著輸送機(jī)兩側(cè)把開關(guān)連接起來。當(dāng)輸送帶設(shè)備發(fā)生緊急事故時(shí),在現(xiàn)場沿線任意處拉動(dòng)鋼絲繩,鋼絲繩牽動(dòng)驅(qū)動(dòng)臂旋轉(zhuǎn),通過傳動(dòng)軸帶動(dòng)扭力彈簧使精密凸輪發(fā)生位移,驅(qū)動(dòng)微動(dòng)開關(guān)切斷控制線路,使得輸送機(jī)停止運(yùn)行。
安裝和調(diào)整
拉繩開關(guān)應(yīng)安裝在輸送機(jī)兩邊具有檢修通道的地方,安裝位置應(yīng)確保檢修人員在緊急情況下操作方便。
1、將拉繩開關(guān)固定在機(jī)架上。
2、一側(cè)的兩臺(tái)開關(guān)之間距離為50m左右,采用直徑為Φ4的鋼絲繩連接,松緊應(yīng)適度。
3、為減小鋼絲繩自重對(duì)開關(guān)啟動(dòng)的影響,每隔3m在機(jī)架上裝一個(gè)托環(huán),以支撐鋼絲繩。
4、鋼絲繩的另一端系在拉簧上(用繩扣固定),在不影響正常使用下用緊線器將兩側(cè)拉繩張緊,并確保兩側(cè)張力均衡。
(注:對(duì)于爬坡段輸送機(jī)機(jī).應(yīng)盡量縮短開關(guān)間距及拉繩長度。)
