The invention discloses a self-resetting redundant anti-collision sensor, which comprises a shell and a steel wire rope, a resetting mechanism for accommodating the steel wire rope is arranged on the shell, the resetting mechanism comprises a rotating shaft, a reel is arranged on the rotating shaft, and the steel wire rope is wound on the reel; a detection mechanism is arranged in the shell, the detection mechanism comprises a microswitch and a detection wheel, and the rotating shaft is connected with the detection wheel through a transmission mechanism; when the sensor is in a use state, the steel wire rope is pulled out of the shell, the end of the steel wire rope is fixed, the steel wire rope drives the rotating shaft to rotate through the reel under the condition that the steel wire rope is pulled by external force, the rotating shaft drives the detection wheel to rotate through the transmission mechanism, and the elastic piece of the microswitch is separated from the concave part of the detection wheel and generates a protection signal. The anti-collision sensor can be automatically reset, meanwhile, protection signals can be continuously formed along with the fact that the steel wire rope can be pulled out, and the safety of operators is effectively protected.
本发明公开了一种自复位冗余型防碰撞传感器,包括壳体、钢丝绳、壳体上设有收纳钢丝绳的复位机构,复位机构包括转动轴,所述转动轴上设置有卷盘,所述钢丝绳缠绕于卷盘上;所述壳体内设有检测机构,所述检测机构包括微动开关和检测轮,所述转动轴与所述检测轮通过传动机构连接;当传感器处于使用状态时,钢丝绳由壳体内拉出并对钢丝绳端部进行固定,钢丝绳受到外力牵扯的情况下通过卷盘带动转动轴转动,转动轴通过传动机构带动检测轮转动,所述微动开关的弹片脱离所述检测轮的凹陷内并生成保护信号,本发明能够实现防碰撞传感器的自动复位,同时随着钢丝绳可拉出可以连续形成保护信号,有效保护了操作人员的安全。
