The invention provides an elevator lifesaving safety platform. The elevator lifesaving safety platform comprises a base plate, an upper plate, a plurality of oil columns, an oil tank, a fixing device, an oil port adjusting device and a linkage device. The lower side of the fixing device is provided with an oil cavity. The oil cavity is communicated with the oil columns through oil pipes. An oil outlet is formed in the bottom of the oil cavity and communicated with the oil tank. The bottom of the oil port adjusting device is matched with the oil outlet. The oil port adjusting device is provided with a first position and a second position, wherein the oil port adjusting device does not make contact with the oil outlet at the first position and makes contact with the oil outlet at the second position. The fixed end of the linkage device is fixedly connected with the upper plate, and the movable end of the linkage device is in linkage fit with the oil port adjusting device. Due to the fact that the oil port adjusting device is arranged inside the fixing device, and the linkage device is in linkage with the upper plate, when an elevator falls down to the ground, the upper plate is driven through the inertia effect to move downwards; when the pressure reaches the set value, a safety film is fractured, the upper plate moves downwards, the linkage device is driven to move and the oil port adjusting device is driven to adjust the size of the oil outlet; and buffering is provided, meanwhile, the falling speed of the elevator can be decreased, and it is ensured that the elevator can stably reach the ground when falling.
