English Introduction
The JY3/PK-12-30 pull cord switch is a safety protection device widely used in industrial conveying systems. It is primarily designed to quickly stop conveying equipment in emergency situations to ensure the safety of both equipment and personnel. This switch features a robust cast aluminum housing with an IP65 protection rating, which effectively guards against dust and moisture ingress. This makes it suitable for long-term use in harsh industrial environments.
The working principle of the JY3/PK-12-30 pull cord switch involves triggering the switch action by pulling the cord. When an abnormal situation occurs in the conveying system, operators can pull the cord to activate the switch, thereby cutting off the power supply or sending an alarm signal. This pull cord switch has a bidirectional triggering function and can be installed either in the middle of the conveyor or at its ends. Its universal installation design allows for flexible adaptation to different installation requirements. Additionally, the integral cover design makes wiring and switch adjustment convenient and simple without the need to disassemble the switch.
The JY3/PK-12-30 pull cord switch is suitable for a variety of industrial applications, such as material conveying systems in mining, metallurgy, ports, and power generation industries. It provides reliable protection by quickly stopping the equipment in case of failure or when an emergency stop is required by personnel, reducing accident losses and enhancing the safety and reliability of the system.

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。)
