Product Overview
The GYLS-I pull-wire switch is an emergency stop protection device specifically designed for belt conveyors. Featuring a bidirectional triggering mechanism, it can be installed at any point along the conveyor line. During emergencies, pulling the connected wire rope activates the stop signal, safeguarding both equipment and personnel. Its die-cast aluminum housing combines high strength with lightweight properties, supplemented by anti-corrosion surface treatment for durability in harsh industrial conditions including dust and moisture. 2324
Key Features
Available in manual-reset and auto-reset variants: the manual type maintains position via a self-locking mechanism requiring manual intervention, while the auto type returns to default state upon tension release. Equipped with precision micro-switches and copper tube transmission, it achieves high sensitivity with 2ms response time. IP65-rated protection ensures reliable operation amid vibration, oil exposure, or temperature fluctuations. Dual rope arms enable bidirectional emergency activation. 4617
Applications
Widely adopted in bulk material handling systems across steel, cement, power, and port industries, including standard belt conveyors, bucket elevators, and ship-loading equipment. Particularly suitable for automated production lines requiring centralized control, it interfaces with control systems via switch signals to optimize operational efficiency. Provides rapid response for conveyor misalignment, material blockage, or mechanical failures. 91623
Specifications
Operates at 220V/380V AC with ≤5A load current, functioning within -20℃ to +60℃. Trigger force is 50±10N with >100,000 mechanical cycles. Includes 1.2m 4-core cable and configurable NO/NC contacts. Recommended installation spacing is 30-50m using 3-5mm plastic-coated wire ropes supported by guide rings every 3m. For inclined conveyors, reduce spacing to 25m. 51425
Installation & Support
Mounts via bolts on conveyor side beams, with detailed diagrams provided. Optional accessories include coated wire ropes and clamps. Rigorous aging tests and scenario simulations ensure reliability. Maintenance involves checking lever position, cam status, and terminal tightness. Customized solutions like explosion-proof or high-temperature models are available. 71826

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(chǎng)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(jiǎn)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(chǎng)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(chǎng)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(zhǎng)度。)
