The invention provides a gantry crane cable-stayed protection device which comprises an insulating part, a cable-stayed protection part, a cable-stayed protection part and a cable-stayed protection part. The middle of the insulating part is provided with a center hole for a gantry crane steel wire rope to penetrate through. The limiting protection frame comprises limiting rings fixed below the insulating part at intervals, and the steel wire rope is arranged in the limiting rings in a penetrating mode; the protector is configured to be capable of shutting down the gantry crane when being triggered; the steel wire rope and the limiting ring form a normally-open switch, and the normally-open switch and the protector are electrically connected to a control loop. In response to determining that the steel wire rope is separated from the limiting ring, the control loop is open; in response to determining that the steel wire rope inclines to be in contact with the limiting ring, the control loop is conducted to trigger the protector. According to the gantry crane cable-stayed protection device provided by the utility model, when the gantry crane is cable-stayed, the normally-open switch is in a closed state, and the control loop conduction protector is triggered to stop the gantry crane at the moment, so that greater potential safety hazards caused by continuously cable-stayed lifting of goods are avoided.
本申请提供一种龙门吊斜拉保护装置,包括:绝缘件,中部设有用于穿设龙门吊钢丝绳的中心孔,以使绝缘件随钢丝绳水平移动;限位保护架,包括间隔固定于绝缘件下方的限位环,钢丝绳穿设于限位环内;保护器,被配置为触发时能够关停龙门吊;钢丝绳和限位环形成常开开关,常开开关与保护器电性连接于控制回路;响应于确定钢丝绳与限位环分离,控制回路为断路;响应于确定钢丝绳倾斜至与限位环接触,控制回路导通触发保护器。本申请提供的龙门吊斜拉保护装置,当龙门吊发生斜拉时,该常开开关为闭合状态,此时控制回路导通保护器被触发致使龙门吊关停,避免继续斜拉提升货物而造成更大的安全隐患。
