English Product Description
Product Overview
The XTD-PK pull-wire switch is an emergency stop protection device designed for conveyor systems, including belt conveyors, bucket elevators, and stacking/reclaiming systems. In case of emergencies, pulling the installed wire rope along the equipment will immediately trigger the switch to halt operation, ensuring personnel safety and preventing mechanical damage. Its bidirectional activation allows flexible installation at both intermediate or terminal positions of the conveyor. The durable cast aluminum housing provides weather resistance for long-term use in harsh environments.
Design & Features
Equipped with a dual-bearing transmission mechanism and stainless steel lever, the XTD-PK ensures responsive actuation and wear resistance. It integrates self-cleaning micro-switches with contacts rated at 16A/250V AC (2NO+2NC). The IP65-rated housing effectively blocks dust and water ingress, suitable for temperatures ranging from -20℃ to +60℃. Complete accessories include galvanized wire ropes, clamps, and support bolts. Installation requires rope supports every 3 meters, with max span distances of 40m (horizontal) or 30m (inclined).
Applications
Ideal for bulk material handling in industries like metallurgy, mining, cement, and power plants, this switch is compatible with diverse equipment such as shuttle conveyors and ship loaders. Its bidirectional trigger enables emergency stops from any point along the conveyor line, making it critical for long-distance transport safety. For example, multiple XTD-PK units can be deployed along both sides of conveyors in mining sites to create a comprehensive safety network.
Installation & Maintenance
Mount the switch on accessible brackets near conveyor walkways. Use Φ4mm plastic-coated wire ropes tensioned via turnbuckles. Regular maintenance involves cleaning the housing to prevent dust accumulation exceeding 3mm. For inclined conveyors, closer switch spacing is recommended to offset rope sag. The tool-free cover design simplifies wiring adjustments without disassembly.
Key Advantages
The XTD-PK offers exceptional reliability with a mechanical lifespan exceeding 500,000 cycles and adjustable actuation angles (15°~75°). The lightweight yet corrosion-resistant aluminum housing features high-visibility color coding (black arm/yellow body) for status identification. Manual lever reset functionality locks the stop position to prevent accidental restarts during maintenance.

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(guó)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。）
