水泥拉绳开关_双向_LXA-34T1-A底价包邮俗称紧急停机开关。作用于带式输送机现场需要停机时，通过开关动作使输送机停机。双向拉绳开关广泛用于钢铁、水泥厂、电厂矿山等具有带式输送机的矿厂，该产品安装在胶带输送机两侧，是用于胶带输送机紧急事故的一种保护开关。
双向拉线开关LXA-34T1-A是带式输送机必备的安全保护装置，防止事故的扩大而带来重大损失，当胶带运输机现场发生紧急事故时，可拉动系于摆臂上的钢丝绳，使摆臂旋转而带动机内凸轮并感应微动开关，发出停机信号。

•内藏性能微动开关和无需加油的滚珠轴承
•内藏停止用和报警2个接点
•可附动作指示杆产品
•采用旋转式凸轮结构，动作行程大，灵敏度且不易卡死。
•耐久性卓越主要组成部分
双向拉绳开关主要是由拉杆、凸轮、复位柄、锁槽、微动开关等部件组成。拉绳开关安装于皮带式输送机两侧机架之上，采用钢丝绳沿着输送机设备两侧将开关连接起来。在输送带设备发生紧急事故情况下时，在输送机沿线任意处拉动钢丝绳，钢丝绳将会牵动驱动臂开始旋转，通过传动轴从而带动扭力弹簧使精密的凸轮发生位移，驱动双向拉绳开关切断控制线路，使得输送机快速的停止运行。

安装和调整
拉绳开关应安装在输送机两边具有检修通道的地方，安装位置应确保检修人员在紧急情况下操作方便。
1、将拉绳开关固定在机架上。
2、一侧的两台开关之间距离为50m左右，采用直径为Φ4的钢丝绳连接，松紧应适度。
3、为减小钢丝绳自重对开关启动的影响，每隔3m在机架上装一个托环，以支撑钢丝绳。
4、钢丝绳的另一端系在拉簧上(用绳扣固定),在不影响正常使用下用紧线器将两侧拉绳张紧,并确保两侧张力均衡。
Two-way pull rope switch commonly known as emergency stop switch. The conveyor will be shut down by the switch action when it needs to stop at the site of belt conveyor. Two-way stretching wire switch is widely used in iron ａnd steel, ment plants, power plants, mining, etc have mine belt conveyor, this product is installed on both sides of belt conveyor, is a kind of protection to the belt conveyor emergency switch.
34 t1 - A two-way pull switch LXA - is essential safety devi of belt conveyor, prevent accident expanding ａnd bring great losses, when the belt conveyor on-site emergency accidents, can pull on the rope on the swing arm, ａnd with motivation in CAM rotary swing arm ａnd induction micro switch, signal downtime.
The performan characteristics of
• the shell is made of high pressure cast stainless steel with light weight.
• high strength surfa with electrostatic coating, strong adhesion ａnd uniform coating.
• protection grade IP67.
• high performan micro switch ａnd no refueling ball bearings.
• stop using ａnd alarm 2 contacts.
• production of attached motion indicator bar products.
• adopt rotary CAM structure, with large movements, high sensitivity ａnd easy to die.
• exllent durability.
Main component
The two - way pull - rope switch is mainly composed of pull rod, CAM, reset handle, slot, micro - switch ａnd so on. The pull cord switch is mounted on the rack on both sides of the belt conveyor, ａnd the wire rope is used to connect the switch on both sides of the conveyor. In conveyor equipment emergency accident cases, at any position along the conveyor pull wire rope, wire rope will affect driving arm begins to spin, through the drive shaft to drive the torsion spring displament in the precision of the CAM, drive the two-way stretching wire switch to cut off the control circuit, makes the conveyor quickly stop running.
