Pull Cord Switch SPS-2D: A Reliable Safety Solution
The Pull Cord Switch SPS-2D is a safety device specifically designed for industrial conveying systems. It plays a crucial role in ensuring the safety of both equipment and personnel. In a conveyor belt system, if any abnormal situations occur, such as material blockage or belt misalignment, the operator can simply pull the cord of the switch to immediately cut off the power supply of the equipment, bringing the conveyor to a halt. This action helps prevent further escalation of accidents, reducing the risk of equipment damage and personal injury.
This pull cord switch features a robust and durable housing, making it suitable for various harsh industrial environments, including dusty, humid, and high-temperature conditions. The internal mechanical structure of the switch is meticulously designed to ensure sensitive and reliable operation. Even with frequent use, it maintains stable performance.
The length of the pull cord can be customized according to the actual length of the conveyor. This ensures that the switch can be triggered conveniently from any location along the conveyor. In terms of installation and usage, the Pull Cord Switch SPS-2D is extremely user-friendly. It can be easily mounted on the sides of the conveyor using simple brackets. The pull cord is arranged along the length of the conveyor, allowing operators to quickly operate the switch in emergencies. Additionally, the electrical connection of the switch is straightforward. It can be easily integrated into the control system of the conveyor to achieve emergency stop control of the equipment.
The Pull Cord Switch SPS-2D is a practical and efficient safety device. It provides a reliable safety solution for industrial conveying systems and is an essential safety component for various types of conveyors. Whether in mines, ports, factories, or logistics centers, the Pull Cord Switch SPS-2D can safeguard your conveying system, ensuring the safety and stability of the production process.

拉绳开关(Pull Cord Switch)俗称“紧急停机开关”。作用于带式输送现场需要停机时,通过开关动作使输送机停机。
适用范围:
拉绳开关广泛用于冶金、煤炭、水泥、采矿、电力、港埠、化工等域的各种专门从事散料输送的输送设备。
简介
拉绳开关分为手动复位和自动复位两种,需要达到国家规定IP等级。
自动复位:动作后后能自动回到初始位置,可能会造成误差启动。
手动复位:动作后有自锁装置能保持在操作位置上,需要手动操作复位手柄可使其返回初始位置。
拉绳开关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。由于安装方便,开关转换可靠,在带式运输现场得到广泛的应用。
结构和基本原理
拉绳开关由拉杆、复位柄、凸轮、锁槽及微动开关等组成。
拉绳开关安装于皮带输送机的两侧的机架上,用钢丝绳沿着输送机两侧把开关连接起来。当输送带设备发生紧急事故时,在现场沿线任意处拉动钢丝绳,钢丝绳牵动驱动臂旋转,通过传动轴带动扭力弹簧使精密凸轮发生位移,驱动微动开关切断控制线路,使得输送机停止运行。
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。
(注:对于爬坡段输送机机.应尽量缩短开关间距及拉绳长度。)
