The invention belongs to the field of vertical supporting legs playing a supporting role, and particularly relates to a safety clamping device for a vertical supporting leg, the safety clamping device comprises a U-shaped safety clamping structural body, the U-shaped bottom of the safety clamping structural body is provided with a U-shaped groove, and the safety clamping structural body is provided with hinge holes in two side plates at the opening end of the U-shaped groove. A U-shaped supporting plate is arranged at the supporting end, away from the hinge holes, of the safety clamping structural body, and the outer supporting face of the supporting plate is not lower than the end face of the supporting end of the safety clamping structural body. After the vertical supporting leg is provided with the safety clamping device, when the vertical supporting leg plays a supporting role, the safety clamping device is erected and placed below a fixed supporting leg, once the vertical supporting leg is soft due to oil leakage of an oil cylinder or internal unloading and the like between a movable supporting leg and the fixed supporting leg, the fixed supporting leg and the safety clamping device are clamped, so that the fixed supporting leg can be prevented from continuously falling off, and the gravity center shift and the side tipping of mechanical equipment are avoided.

    本发明属于起到支撑作用的垂直支腿领域,具体涉及一种用于垂直支腿的安全卡装置,该安全卡装置包括U型的安全卡结构体,安全卡结构体的U型底部设有U型槽,安全卡结构体在U型槽开口端的两侧板上设有铰接孔,安全卡结构体远离铰接孔的支撑端设有U型的支撑板,支撑板的外支撑面不低于安全卡结构体支撑端的端面。垂直支腿安装有安全卡装置后,在垂直支腿起支撑作用时,将安全卡装置竖起放在固定支腿的下方,活动支腿与固定支腿间一旦出现油缸漏油或内卸等导致垂直支腿软腿时,固定支腿和安全卡装置卡死,能够防止固定支腿继续下落,避免机械设备出现重心偏移,发生侧面倾翻。
