產(chǎn)品詳情 Product details

本機(jī)用于膠帶運(yùn)輸機(jī)發(fā)生事故時(shí)緊急停機(jī)。開(kāi)關(guān)為雙向觸動(dòng)式，一端固定在拉繩螺栓，另一端固定在開(kāi)關(guān)臂上，開(kāi)關(guān)到固定點(diǎn)距離不超過(guò)25米，開(kāi)關(guān)間距離不超過(guò)30米，當(dāng)外力促使開(kāi)關(guān)臂桿，轉(zhuǎn)動(dòng)到報(bào)警（停機(jī)）位置時(shí)，開(kāi)關(guān)鎖定，本機(jī)為手動(dòng)復(fù)位機(jī)型，在故障排除后按下限位桿方能復(fù)位。

2.工作原理
當(dāng)膠帶運(yùn)輸現(xiàn)場(chǎng)發(fā)生緊急事故時(shí)，可拉動(dòng)系在拉繩開(kāi)關(guān)吊耳上的鋼絲繩，時(shí)機(jī)內(nèi)的滑塊控制內(nèi)部微動(dòng)開(kāi)關(guān)動(dòng)作，發(fā)生停機(jī)或警報(bào)信號(hào)。自動(dòng)復(fù)位機(jī)型在松開(kāi)鋼絲繩后自動(dòng)復(fù)位，手動(dòng)復(fù)位機(jī)型需操作復(fù)位手柄后方可復(fù)位。

3.使用與安裝
1、開(kāi)關(guān)平衡地按在機(jī)架的固定支架上;將鋼絲繩系在兩端的拉環(huán)上，每側(cè)繩不超
2、過(guò)30M（有坡度時(shí)應(yīng)當(dāng)縮短〕;
3、拉繩動(dòng)作力應(yīng)適宜，以確保開(kāi)關(guān)可靠復(fù)位;
4、鋼絲繩沿膠帶平行方向設(shè)置，每10M加一個(gè)吊環(huán);

4.主要技術(shù)參數(shù)

The switch is bi-directional, one end is fixed to the drawstring bolt, and the other end is fixed to the switch arm. The distancebetween the switch and the fixed point is not more than 25 meters, and the distance between the switches is not more than 30meters. In the stop position, the switch is locked.The machine is a manual reset model.After the fault is removed, the limit levercan be reset.

2.working Principle

When an emergency occurs at the tape transportation site, the steel wire rope attached to the rope switch liting ears can bepulled, and the slider in the timing controls the internal micro-switch action, and a shutdown or alarm signal occurs.Automaticreset models automatically reset after loosening the wire rope, manual reset models can only be reset after operating the resethandle.

3.Use & Installation

1.Press the switch in a balanced manner on the fixed bracketof the rack.Tie the steel wire rope to the pull rings at both ends,and the rope on each side should not exceed 30M(it should beshortened when there is a slope).

2.The pulling force should be appropriate to ensure the reliablereset of the switch.

3.The steel wire rope is set along the parallel direction of thetape,and a lifting ring is added every 10M.
