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.
