The invention relates to a traction elevator roof rushing detection device which comprises a rack, an installation frame and a supporting cover are vertically installed on the rack in a sliding mode, an elastic bearing mechanism is arranged on the installation frame, the installation frame abuts against the supporting cover through the bearing mechanism, an elevator counterweight is hung on the installation frame, and an alarm elastic piece is installed in the supporting cover. The two ends of the alarm elastic piece abut against the supporting cover and the rack respectively, the minimum pressure of the bearing mechanism on the supporting cover is larger than the thrust of the alarm elastic piece on the supporting cover, a trigger switch connected with an alarm system is installed on the top wall of the rack, and a trigger rod of the trigger switch abuts against the top wall of the supporting cover. When the elevator runs normally, the bearing mechanism abuts against the supporting cover, the supporting cover is static when the elevator runs normally, when the elevator rushes to the top, the counterweight pier bottom weightlessness is achieved, the pulling force of the counterweight on the bearing mechanism disappears, the supporting cover bounces upwards under the thrust of the alarm elastic piece, the trigger rod starts the trigger switch, and the trigger switch starts the alarm system to give an alarm.
本申请涉及一种曳引电梯冲顶检测装置,包括机架,机架上竖直滑移安装有安装架和支撑罩,安装架上设有弹性承重机构,安装架通过承重机构抵紧支撑罩,电梯对重挂在安装架上,支撑罩内安装有警报弹性件,警报弹性件的两端分别抵紧支撑罩和机架,承重机构对支撑罩的最小压力大于警报弹性件对支撑罩的推力,机架顶壁上安装有连接警报系统的触发开关,触发开关的触发杆抵紧支撑罩的顶壁。电梯正常运行时,承重机构抵紧支撑罩,支撑罩在电梯正常运行时静止,电梯冲顶时,对重墩底失重,对重对承重机构的拉力消失,支撑罩在警报弹性件的推力下向上弹起触发杆启动触发开关,触发开关启动警报系统报警。
