DLK2-15B-H Bidirectional Rope Switch (English Introduction)
Product Overview
The DLK2-15B-H bidirectional rope switch, also known as an "emergency stop switch," is a critical safety device for belt conveyors and bulk material handling systems. It enables immediate equipment shutdown by activating a pull-wire mechanism at any point along the conveyor line. Constructed with aluminum alloy housing, the switch offers durability and lightweight performance, complemented by corrosion-resistant finishes for harsh environments. Its dual reset modes (manual or automatic) cater to diverse operational requirements.1517
Key Features
Equipped with a robust cam-driven mechanism, the switch ensures reliable signal triggering upon rope actuation. The IP67-rated enclosure provides dustproof and waterproof protection, while bidirectional operation allows flexible installation. Manual reset models feature a locking function to prevent unintended restarts, whereas auto-reset variants streamline frequent use. Installation guidelines recommend 4mm diameter steel ropes with tension adjusters and support brackets to minimize sagging interference. Compatible with conveyors, elevators, and cranes, it serves as a versatile safety solution.31221
Technical Specifications
Operating within -40°C to 60°C and ≤85% humidity, the switch spans 30-50m intervals (shorter for inclined sections). Mounting on accessible frame sides ensures swift emergency access. Wiring utilizes a 4-core rubber cable with NO/NC contacts for seamless control integration. The optimized cam structure enhances longevity, while sealed components resist vibration, chemicals, and moisture.51320
Applications
Ideal for mining, cement, and logistics sectors, this switch safeguards long-distance conveyors, stackers, and similar machinery. Instant circuit interruption mitigates risks during emergencies, aligning with industrial safety protocols. Optional accessories like coated cables and mounting kits further enhance system stability.11524

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)間距及拉繩長度。)
