Product Overview
The YH25-1 pull cord switch is a bidirectional emergency stop device designed for belt conveyor systems, widely used in industries such as metallurgy, power, cement, and mining for bulk material handling. Its durable cast aluminum housing combines high strength with lightweight properties, featuring an IP65 protection rating for reliable operation in harsh environments. The switch s distinctive arm design ensures clear visibility of operational status, while the manual lever reset function allows quick recovery after emergency shutdowns.
Connected via steel cables along conveyor sides, the switch activates immediately upon pulling the cable at any point, cutting off control circuits to halt equipment operation, safeguarding both personnel and machinery. The universal mounting design accommodates installation on conveyor beams (top or sides), adapting to diverse structural requirements. 131518

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,通過開關(guān)動作使輸送機(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)分為手動復(fù)位和自動復(fù)位兩種,需要達(dá)到國家規(guī)定IP等級。
自動復(fù)位:動作后后能自動回到初始位置,可能會造成誤差啟動。
手動復(fù)位:動作后有自鎖裝置能保持在操作位置上,需要手動操作復(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,在現(xiàn)場沿線任意處拉動鋼絲繩,鋼絲繩牽動驅(qū)動臂旋轉(zhuǎn),通過傳動軸帶動扭力彈簧使精密凸輪發(fā)生位移,驅(qū)動微動開關(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開關(guān)啟動的影響,每隔3m在機(jī)架上裝一個托環(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。)
