The utility model discloses a test device for detecting the vertical bearing capacity of a bridge tower climbing cone. The device comprises an enlarged foundation bottom plate arranged at the bottom of a climbing cone to be measured, wherein an n-shaped frame is arranged on the expanded foundation bottom plate, a climbing cone force bearing piece is arranged on the climbing cone to be measured, aclimbing cone bearing base is arranged on the climbing cone force bearing piece, a jack is arranged on the climbing cone bearing base, the climbing cone bearing base is arranged in the n-shaped frame,and the jack abuts against the inner top surface of the n-shaped frame. The device has the advantages that the automation level can be improved, a tester does not need to record data in real time onsite, the requirement of real-time monitoring can be met, and fault diagnosis can be carried out on the device without detecting state parameters in real time.
