產(chǎn)品詳情 Product details

雙向拉繩開關(guān)廣泛應(yīng)用于鋼鐵、水泥、電廠、礦山等具有帶式輸送機(jī)的廠礦﹔該產(chǎn)品安裝在股帶輸送機(jī)兩側(cè)，是用于媵帶輸送機(jī)緊急事故停機(jī)的一種保護(hù)開關(guān)，在開關(guān)操作距離內(nèi)任何一點(diǎn)拉動鋼絲繩，切斷運(yùn)行電路使全線停機(jī)，實(shí)現(xiàn)對膠帶機(jī)及人身安全的保護(hù)。

2.工作原理
當(dāng)膠帶運(yùn)輸現(xiàn)場發(fā)生緊急事故時，可拉動系在拉繩開關(guān)吊耳上的銅絲縮，使機(jī)內(nèi)的滑塊與開關(guān)作用，發(fā)出停機(jī)信號。松開鋼絲繩后自動復(fù)位。

3.使用與安裝
1、開關(guān)平衡地按在機(jī)架的固定支架上;
2、將鋼絲○系在兩端的拉環(huán)上,每側(cè)繩不超過40M目有被度時應(yīng)當(dāng)縮短為25M} ;
3、拉繩動作力應(yīng)適宜，以確保開關(guān)可靠復(fù)位;
4、鋼絲繩沿膠帶平行方向設(shè)置,每3NM加一個吊環(huán);

4.主要技術(shù)參數(shù)

The two-way pull rope switch is widely used in steel, cement, power plants, mines and other factories with belt conveyors.Thisproduct is installed on both sldes of the belt conveyor.Pull the wire rope at any point within the operating distance, cut off therunning circuit to stop the whole line, and realize the protection of the belt conveyor and personal satety.

2.Working Principle
When an emergency occurs at the tape transportation site , the steel wire rope attached to the liting ears of the rope switch canbe puled to make the allder and switch in the machine act and issue a shutdown signal. Automatically reset after loosening thewire rope.

3.Use & Installation
1.Press the switch in a balanced manneron the fixed bracket of the rack.
2.Tie the steel wire rope to the pullrings at both ends, and the rope on each side should not exceed 40M (it should be shortenedto 25M when there is a slope).
3.The pulling force should be appropriale to ensure the reliable reset of the switch.
4.The steel wire rope is set along the parallel direction of the tape,and a lifting ring is added every 3M.
