產品詳情 Product details

雙向拉(la)繩(sheng)開關(guan)廣泛應用于(yu)鋼鐵、水泥、電廠、礦山等具有帶(dai)(dai)式輸送機(ji)(ji)(ji)的廠礦﹔該產品(pin)安裝在股帶(dai)(dai)輸送機(ji)(ji)(ji)兩側，是用于(yu)媵帶(dai)(dai)輸送機(ji)(ji)(ji)緊急事故(gu)停(ting)機(ji)(ji)(ji)的一種(zhong)保護開關(guan)，在開關(guan)操作(zuo)距離內任何一點拉(la)動(dong)鋼絲繩(sheng)，切斷運行(xing)電路使全線停(ting)機(ji)(ji)(ji)，實現(xian)對膠帶(dai)(dai)機(ji)(ji)(ji)及(ji)人(ren)身安全的保護。

2.工作原理
當膠帶運輸(shu)現(xian)場發(fa)生緊急事故(gu)時，可拉動系在(zai)拉繩開關吊(diao)耳上的(de)銅絲縮(suo)，使機內的(de)滑塊與開關作用，發(fa)出(chu)停機信號。松(song)開鋼絲繩后自動復位(wei)。

3.使用與安裝
1、開(kai)關平衡地(di)按在機架的固定(ding)支架上(shang);
2、將(jiang)鋼絲○系在(zai)兩端的拉(la)環上,每側(ce)繩(sheng)不(bu)超過40M目有被度時應當縮(suo)短為(wei)25M} ;
3、拉(la)繩動(dong)作力應適宜(yi)，以確(que)保開關可靠復位;
4、鋼絲繩(sheng)沿膠帶(dai)平行(xing)方向設置,每3NM加一(yi)個(ge)吊環;

4.主要技術參數

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.
