The invention discloses a detachable long-stroke jack for lowering a rapid steel support, which relates to the technical field of foundation pit construction, and comprises a bottom plate, a heavy frame, two jacks detachably mounted between the bottom plate and the heavy frame, and jack displacement sensors for detecting the stroke of the jacks, the heavy frame is connected and fixed to the extending ends of piston rods of the two jacks, a movable clamping mechanism is installed on the heavy frame, a fixed clamping mechanism is installed on the bottom plate, the movable clamping mechanism and the fixed clamping mechanism coaxially clamp a rigid cylinder, and a clamping displacement sensor is installed beside the clamping conveying path of the movable clamping mechanism and the fixed clamping mechanism; and the heavy frame and the bottom plate are provided with penetrating holes of the rigid column body. The problems that an existing steel support hoisting device is large in occupied area, high in cost and large in safety risk when hoisting a rapid steel support are solved.

    本发明公开了一种用于下放快速钢支撑可拆卸长行程千斤顶,涉及基坑施工技术领域,它包括底板、承力架和可拆卸安装在底板、承力架之间的两个千斤顶和用于检测千斤顶行程的千斤顶位移传感器,承力架连接固定于两个千斤顶的活塞杆伸出端,承力架上安装有运动夹持机构,底板上安装有固定夹持机构,运动夹持机构和固定夹持机构同轴夹持刚性柱体,运动夹持机构和固定夹持机构的夹持传送路径旁安装有夹持位移传感器;承力架和底板开设有刚性柱体的穿装孔。本发明解决了现有钢支撑吊装设备吊装快速钢支撑存在占地大、成本高、安全风险大的问题。
