雙向拉繩開關(guān)WZHB-GKXJ-20防爆

雙向拉繩開關(guān)WZHB-GKXJ-20防爆原理

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。

雙向拉繩開關(guān)WZHB-GKXJ-20防爆安裝調(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。）
