Hydraulic climbing device and supporting falling protector thereof

The utility model relates to a hydraulic climbing device and a supporting falling protector of the hydraulic climbing device. The supporting falling protector comprises a box body and a one-way jaw. The one-way jaw can stretch and can be rotationally installed in the box body in the axial direction of the one-way jaw. The stretching direction of the one-way jaw is perpendicular to the motion direction of the hydraulic climbing device. An ejector part which can make contact with a fixing structure is arranged at one end of the one-way jaw, and a slope and a plane which can make contact with the fixing structure are arranged on the two sides, in the motion direction of the hydraulic climbing device, of the ejector part respectively. In the initial state, the ejector part is exposed out of the box body. The hydraulic climbing device and the one-way jaw of the supporting falling protector of the hydraulic climbing device are installed in the box body in a stretchable mode, the occupied space of the box body is sm
